[the_novelty] => In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of "Single Energy Interval Value (SEIV)" and "Energy Spectrum Total Value (ESTV)", which significantly improved the production efficiency of isotopes such as 252Cf (by 15.08 times), 244Cm (by 65.20 times), 242Cm (by 11.98 times), and 238Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.
[the_background] => The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as 252Cf, 244Cm, 242Cm, and 238Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.
[the_sdg_impact] => The limited production rate of transplutonium isotopes poses a significant challenge in meeting the growing demand for sustaining the nuclear industry (i.e. energy and military). This research provides a sustainable solution to improve the efficiency of transplutonium isotope production through a novel rapid diagnostic method. Thus, it fulfils UNSDG 7 (Affordable and Clean Energy) by providing a sustainable source of energy, as well as UNSDG 9 (Industry, Innovation and Infrastructure) by promoting technological innovation in the nuclear industry, especially for military use.

[video] =>
[the_novelty] => This study thoroughly proposed the design of Megahertz cavIty eNhanced x-ray Generation (MING) which was meant to be set up in China’s first hard X-ray free-electron laser (XFEL) facility i.e. SHINE. The proposal covers crucial topics like principles and performance of MING, key components of MING, as well as X-ray transport and diagnostics. MING will be equipped with an undulator of period 26 mm and crystal cavity, covering the energy range of 6–15 keV. Moreover, MING will be able to generate X-ray with pulse bandwidth of a few tens of meV, while the pulse energies can achieve 300 µJ, corresponding to the spectral brightness increased by 2-3 orders of magnitude. Besides producing high-intensity fully coherent X-rays, MING allows for full control of the polarization of X-rays and can also deliver orbital angular momentum (OAM) light, indicating its superb scalability. To-date, the first cavity-based XFEL facility is yet to be completed. Therefore, the proposal of MING would definitely broaden scientists’ horizon on cavity-based XFEL’s potential and applications, leading to groundbreaking discoveries.
[the_background] => X-ray free-electron laser (XFEL) is a new generation X-ray source which facilitates the rapid progress of multiple research areas. SHINE (China’s first hard XFEL facility), an 8 GeV high-repetition-rate XFEL facility equipped with a continuous-wave (CW) superconducting radio frequency linear accelerator (RF linac), was proposed to be set up in Shanghai in 2017 and estimated to be complete in 2025. Despite being foreseen to deliver brilliant, nearly fully transversely coherent, and ultra-short X-ray pulses, scientists are also aware of its low longitudinal coherence and poor stability. Although the self-seeding technique (for hard X-ray regime) could overcome the problems, high intensity jitter might take place because self-seeding schemes are based on self-amplified spontaneous emission (SASE). Nonetheless, since SHINE will be providing 8 GeV electron bunches at ∼ 1 MHz, it bears the potential to operate a cavity-based XFEL (e.g. XFELOs and RAFELs) which produces fully coherent laser-like X-ray pulses. In order to materialize that within the context of SHINE, this study planned and proposed the design of Megahertz cavIty enhanced X-ray generation (MING) for generating X-rays in the energy range of 6–15 keV. With the optimum design and parameters, MING was predicted to be the key to push the performance of SHINE to a new level.
[the_sdg_impact] => One of the ultimate goals of XFEL is to generate fully coherent pulses and the cavity-based FEL is a promising candidate to achieve this goal. Thus, cavity-based FELs could potentially bring tremendous advancement to various research fields including atomic and molecular science, photon science, and advanced materials. The realization of MING@SHINE will be a remarkable milestone in the evolution of XFELs and, hence, this study is well-aligned with UNSDG 9: Industry, Innovation & Infrastructure.

[video] =>
[the_novelty] => To pursue the exploration of drip line nuclides, this study performed multiple-models predictions to predict the cross-sections of extremely rare isotope (ERI) produced in typical projectile fragmentation (PF) reactions in the Facility for Rare Isotope Beam (FRIB), namely 78,86Kr + 9Be, 58,64Ni + 9Be, and 40,48Ca + 9Be reactions at 140 MeV/u. The multiple-models predictions comprised the EPAX3, FRACS, Bayesian neural network technology (BNN), and BNN + FRACS models. Results showed that both neutron and proton drip lines can be reached for elements of atomic number ≤ 11 with the lowest cross-section of 10−15 mb. The newly created most neutron-rich 39Na verifies the high precision of BNN prediction. Based on the promising results, future studies may apply the proposed methods to enhance the feasibility of creating a larger variety of ERIs in the newly commissioned FRIB factory, leading to more advanced experimental research.
[the_background] => Short-life, unstable, radioactive nuclei are exotic when they develop unusual structures. In order to facilitate the advancement of research, modern rare isotope beam (RIB) factories were set up to enhance the production of extremely rare isotopes (ERI) at or near drip lines. The ERI can be produced more effectively via a higher-level understanding on the projectile fragmentation reactions. As an effort to achieve that, this study performed multi-models predictions of cross-sections for ERIs in typical reactions using EPAX3, FRACS, BNN, and BNN + FRACS models, of which the BNN and BNN + FRACS models were newly developed massive learning models using Bayesian Neural Networks. The output of the study confirmed the feasibility to create a significantly large number of new isotopes in FRIB, leading to a richer knowledge base for nuclear structure, nuclear reaction, and nuclear astrophysics.
[the_sdg_impact] => The new rare isotope factories provide unique technology to extend the boundaries on the chart of nucleus in experiments. This study shows how far from the β-stability line the ERI can reach within the lowest detecting limitations in the newly commissioned FRIB in Michigan State University, USA. By supporting future research related to nuclear science, its output is very well-aligned with UNSDG 9: Industries, Innovation & Infrastructure.

[the_novelty] => This study presents the first commissioning results of the coherent scattering and imaging (CSI) endstation (first of five) at the Shanghai soft X-ray Free-Electron Laser (SXFEL). Nanoscale imaging was reconstructed successfully based on the single-shot holograms and coherent diffraction patterns recorded. During the test on gold nanocubes, the diffraction signals extended to the edge of the CCD detector attributing to the ultrahigh peak brilliance of the SXFEL. Besides that, the missing central area was lesser than the central speckle. The reconstructed image allowed accurate estimation of the edge length of the cubic particles. For gold nanospheres, clear interference speckles were observed and they indicated the presence of multiple nanosphere. Moreover, the test on mitochondria proved the high feasibility of the CSI endstation for “diffraction before destruction” experiments. High-contrast mitochondria structures could be observed (without sectioning) due to the penetration depth and unique imaging opportunities for high contrast in the “water window” energy range (wavelength between 4.40 to 2.33nm). Upon performing a fast Fourier transform of a gold film hologram, both the Fourier transform holography (FTH) image and the reconstructed image (using phase retrieval techniques) were consistent with the scanning electron microscope (SEM) results. Other than commissioning the remaining four endstations in year 2022, the cryogenic sample environment, aerosol sample injector, high-performance detector with a large dynamic range, and optical pump lasers will also be commissioned for in situ and time-resolved experiments at the CSI endstation.
[the_background] => X-ray-based microscopes have been used for high-resolution nanoscale imaging to study extremely fine structures. Following the progressive maturity of both coherent X-ray light sources and novel X-ray imaging methods, coherent diffraction imaging (CDI) (i.e. a novel lensless imaging method) has been developed to examine fine structures at nanoscale. Meanwhile, X-ray free-electron lasers (XFELs) are powerful X-ray sources which produce ultra-bright and highly coherent femtosecond pulses. Its advantages include spatial and temporal coherence as well as gigawatt peak power. Taking advantage of the excellent properties of XFEL and CDI, the single-shot diffraction patterns can be recorded with the femtosecond pulses before the radiation damage occurs. Thus, the radiation damage-free structures of samples can be achieved at nanoscale. The Shanghai Soft X-ray Free-Electron Laser Facility (SXFEL) is the first X-ray FEL facility in China. Built on the Shanghai Synchrotron Radiation Facility (SSRF) campus, its X-ray achieves an energy range of 100 – 620 eV while comprising 1.5 GeV linear accelerator, two undulator lines, two beamlines, and five endstations. In Phase 1, the SXFEL consists of 5 proposed endstations meant for different scopes of study, i.e. dynamic scattering and high spatial and temporal imaging, ultrafast physical phenomena, surface and ultrafast chemical processes, as well as atomic and molecular physics. The high temporal and spatial resolution falls under the role of coherent scattering and imaging (CSI) endstation. This study chose the CSI endstation as the first endstation to be commissioned. The successful commissioning of CSI endstation unvealed its high efficiency in high-resolution radiation damage-free imaging at nanoscale.
[the_sdg_impact] => Ultrafast high-resolution nanoscale imaging is an essential characterization technique for studies focusing on functional materials, biological cells, and organelles. The successful commissioning of CSI endstation of SXFEL and its future effort could significantly enhance the advancement of research of various fields. With easier access to the state-of-the-art facilities, limitless achievement can be realized within shorter time frame. Hence, the output of this study fulfils UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => This study revealed a two-step decellularization (TSD) strategy which effectively led to ultra-low in vivo calcification in bovine pericardial bioprosthetic heart valves (BHVs). After the traditional decellularization and glutaraldehyde (GA) cross-linking, the BHV was introduced to a second-step decellularization by employing a mild biosurfactant n-dodecyl-β-D-maltoside. In pre-clinical studies, the TSD strategy remarkably lowered the in vivo calcification from 138.6 to 1.1 μg/mg, while rendering low cytotoxicity and superior mechanical properties in vitro. Based on the outcome, future studies may explore the feasibility to improve the overall properties of bioprosthetic products by using similar types of mild biosurfactants.
[the_background] => Among the common artificial heart valves, bioprosthetic heart valves (BHVs) are preferred over mechanical heart valves for their impressive hemodynamic performance, independence of lifelong anticoagulation, and superior level of anti-infection. The commercial BHVs are usually made of either porcine pericardium (PP) or bovine pericardium (BP) treated by glutaraldehyde (GA). The BHVs’ main cause of failure is calcification which is very likely to be given rise by phospholipids in plasma membranes and intracellular membranes. To overcome calcification, past studies attempted to employ non-glutaraldehyde cross-linking agents and anticalcification treatments but the outcomes were not ideal. In order to pursue further, this study developed a two-step decellularization (TSD) strategy which involved the use of n-dodecyl-β-D-maltoside (DDM) in the mixture of isopropanol (IPA) and phosphate-buffered saline (PBS). The promising output verified the potential of the biosurfactant employed and, thus, created a new research avenue for improving and enhancing the existing interventional bioprosthetic products.
[the_sdg_impact] => In the US, there are 25,000 deaths each year due to heart valve disease. This alarming figure indicates that interventional bioprosthetic products with higher reliability will contribute to the longevity of humans. Hence, by developing effective strategies to enhance the performance and lifespan of BHV, this study shows a good alignment with UNSDG 3: Good Health & Well-being.

[the_novelty] => What are the fundamental features that determine the unique properties of polymers? This review thoroughly discussed the significance of chain flexibility and connectivity in the crystallization of polymers. With regards to chain flexibility, it has been verified that conformational ordering can occur before crystallization. This was assisted by a local interchain order such as bond-orientation order. Furthermore, the mechanism underlying the occurrence of conformational ordering without the assistance of crystal packing has been elucidated. Chain connectivity is crucial for the formation of semicrystalline lamellar stack structure and also for intrachain nucleation. Compared to crystallization of small molecules, polymer crystallization is harder due to chain entanglement which brings in entanglement pressure and leads to higher nucleation barrier. Meanwhile, the entanglement free energy has a major influence in determining crystallization behavior. Based on the review, the author proposed several potential directions to further pursue the investigation in chain flexibility and connectivity.
[the_background] => Chain flexibility and connectivity play pivotal roles in the unique properties of polymer materials, including crystallization, mechanics, and rheology. Nonetheless, the existing theories of polymer crystallization were established based on those of small molecules crystallization without considering the peculiar features of polymer. In order to achieve a better understanding of polymer crystallization, quantitative prediction with molecular details is necessary. Thus, chain flexibility and connectivity must be considered in the molecular theory of polymer crystallization. As an effort to realize that, this review focused on the impact of chain flexibility and connectivity in polymer materials. The output of the review paved a path as part of the critical steps to develop the theory of polymer crystallization.
[the_sdg_impact] => Polymers are indispensable in the facilitation of human life and are crucial for medication, communication, transportation, urbanization and more. The theory of polymer crystallization is listed as one of the top ten challenges in polymer science. Therefore, by revealing why and how polymer chains assemble into semicrystalline state, this study materialized UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => This study demonstrated that the Circular Electron Positron Collider (CEPC) 650 MHz single-cell superconducting radio-frequency (SRF) cavities could achieve ultrahigh accelerating gradient (Eacc) by applying a combination of buffered chemical polishing (BCP) and electropolishing (EP). The values of Eacc achieved were above 40 MV/m. Besides, after medium-temperature furnace baking, the SRF cavities achieved an ultrahigh Q0 of 8 × 1010 at 22 MV/m and an extremely low BCS resistance (RBCS) of ~1.0 nΩ at 2.0 K. Two 650 MHz SRF cavities were involved throughout the process of validating the effect of the combination of BCP and EP. By showing the pivotal roles of surface treatments on the performance of SRF cavities, the research output paved a clear path for future research on large SRF cavities.
[the_background] => The superconducting radio-frequency (SRF) cavity is a crucial component of particle accelerators, such as high-energy colliders, proton/neutron sources, free electron lasers and synchrotron light sources. The Circular Electron Positron Collider (CEPC) is a high-energy collider of the Higgs factory. The collider ring of the CEPC is equipped with hundreds of 650 MHz SRF cavities. To meet the high requirements of accelerators, the SRF cavities must exhibit high accelerating gradient (Eacc) and high intrinsic quality factor (Q0). The cavities are commonly treated by either buffered chemical polishing (BCP) or electropolishing (EP). However, SRF cavities processed by BCP face challenge in achieving high Eacc, owing to the high surface roughness brought about by BCP. On the other hand, although EP could render higher Eacc, it is a complicated process which also involves higher cost. As such, it was speculated that the combination of BCP and EP could be a feasible way for large SRF cavities to achieve high Eacc. To validate the feasibility of the combination of BCP and EP, this study applied the combined treatment on two 650 MHz SRF cavities and excellent results were obtained. Since the treatment procedures can be replicated easily, the output facilitates the advancement of future studies related to SRF.
[the_sdg_impact] => Particle accelerators play an important role in the advancement of high-energy and nuclear physics. The performance of SRF cavities is very critical as they greatly affect the scale and cost of particle accelerators. In order to contribute to the advancement of research related to SRF, this study developed a highly-feasible and remarkable technique which significantly enhanced the performance of 650 MHz SRF cavities. Therefore, its output showed good alignment with UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => The JMCT3.0 (Joint Monte Carlo Transport 3.0) (latest version) has been coupled with depletion, thermal-hydraulics and fuel property for the simulation of reactor nuclear-hot feedback effects. Besides conducting multiphysics coupled calculations, one of JMCT3.0’s latest features is being able to work with the functions of proton, atmosphere and molecule transport. Since JMCT3.0 was developed based on the combinatorial geometry parallel infrastructure, JCOGIN, and the adaptive structured mesh infrastructure, JASMIN, it supports the geometry bodies, structured and unstructured meshes. Besides that, advanced algorithms (e.g. DD, UTD, OTF, and FCSBC) have been developed for JMCT3.0. Therefore, it is capable of simulating high-complexity device problems such as reactor physics, criticality safety analysis, radiation shielding, detector response, nuclear well logging, dosimetry calculations, and reactor nuclear-hot feedback effects. Moreover, high consistency was obtained by comparing JMCT3.0’s results and those from other state-of-the-art Monte Carlo programs like MC21, OpenMC, and KENO-VI. Future effort is being strategized to enhance the computing efficiency. The complication of uncertainty quantification and propagation of errors is an essential area to consider in the future. Furthermore, new algorithms need to be developed to reduce computing fees and JMCT is evolving progressively towards this goal.
[the_background] => The Monte Carlo method has given rise to the development of multiple physical programs for the study of nuclear science engineering, statistical physics, biomedicine, quantum mechanics, molecular dynamics, petroleum geophysical exploration, finance, information, operational research, polymer chemistry and more. Meanwhile, a general high-performance numerical simulation program JMCT was used to simulate neutron, photon, electron, proton, light radiation, atmosphere, and molecule transport. Especially for those problems which the memory exceeds the limit of a single core or node, JMCT can easily simulate by domain decomposition. At present, JMCT can simulate extremely complicated nuclear system problems and the high-precision numerical simulation results have been obtained. JMCT serves as a crucial complement to the existing numerical simulations for nuclear science studies. It will expand continuously and enhance the facilities as well as speed up the advancement of nuclear research.
[the_sdg_impact] => Via Monte Carlo numerical simulation, the physical quantities can easily obtain both measurable and immeasurable values, especially for some extreme conditions which are inaccessible by experiments. This indicates the necessity to keep enhancing the functions and capabilities of JMCT. Besides, the high upgradability of JMCT shows great potential to fill in the demand gap between numerical simulations and experiments. Hence, by developing JMCT3.0, this study fulfils UNSDG Goal 9: Industry, Innovation & Infrastructure.

[the_novelty] => Is there any room to improve the existing dehydrogenation catalysts? The research of the Energy and Catalysis Adventure Team (ECAT) from Tianjin University shows comprehensively how metal and metal oxide nanostructured catalysts (NCs) can be controlled to enhance the efficiency of propane dehydrogenation (PDH). The efficiency is tackled from three main aspects i.e. the NC’s composition, defects, and confinement. The introduction of promoters and supports contributes to higher PDH efficiency. For metal NCs (e.g. Pt-based), the increase of geometric separation and charge density of surface active sites have successfully increased the PDH efficiency, attributing to the prevented coke deposition and nanoparticles sintering (which can also be inhibited by zeolite framework confinement). The ECAT group has demonstrated that single-atom/intermetallic alloys with higher isolation degree and electron density could be potentially employed for highly efficient PDH processes. For metal oxide NCs (e.g. VOx-based), inducing intrinsic defect sites has increased the PDH efficiency. Dispersion as well as confinement of NC in nanoporous materials could result in higher oxide activity and stability. The feasibility of catalysts based on lower-cost transition metals (e.g. nickel, iron, and cobalt) has been investigated as replacements. The ECAT group has further developed novel processes such as chemical looping oxidative dehydrogenation technology to break the thermodynamic equilibrium limitation of conversion in conventional PDH. The ECAT group currently focuses on the scale-up of the nanostructured catalyst manufacturing and the optimization of PDH process to promote the industrial production of propylene.
[the_background] => The existing commercial-grade Pt- and CrOx-based catalysts have been showing promising performance in the mass production of propylene. However, the need for high working temperature (>500 °C) is causing adverse effects on the overall efficiency of propane dehydrogenation (PDH). Due to the limitations, nanostructured catalysts (NCs) have received attention for their tunable properties to achieve better PDH efficiency. Since the PDH efficiency is held back by the instability of the NCs, this research focuses on optimizing the performance through controllable regulation of metal- and oxide-based NCs. Beyond demonstrating the effective methods to obtain higher PDH efficiency, the outcomes of this research also serve as a significant reference for future studies related to PDH.
[the_sdg_impact] => Propylene, with its global annual production approaching 100 million tonnes, is essential in chemical manufacturing. If its production efficiency can be further enhanced, this will help to maintain the affordability of a wide range of chemicals. In order to realize this goal, this study has come up with feasible and effective methods for more efficient PDH. Thus, by enhancing the research on propylene production, their achievement is very well-aligned with UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => A team of researchers successfully constructed nanofiltration membranes with superior quality using the mussel-inspired deposition methods. Such was achieved via a two-part approach to fabricate the thin-film composite (TFC) nanofiltration membranes. Firstly, the substrate surface was coated through fast and novel deposition to form a dense, robust, and functional selective layer. Then, the structure controllability of the selective layer was enhanced by optimizing the interfacial polymerization (IP) process. As a result, the properties of nanofiltration membranes produced are with high durability and added functionality. When put into a bigger perspective, these high-performance TFC nanofiltration membranes are potential solutions to a number of fields, including water softening, wastewater treatment, and pharmaceutical purification. Hence, there is a need to further explore and expand the application in an industrial scale instead of being bound within the walls of the laboratories.
[the_background] => Membrane-based technologies, especially enhanced nanofiltration systems, have been highly explored due to their myriad of distinct properties, primarily for their high efficiency, mild operation, and strong adaptability. Among these, the TFC nanofiltration membranes are favoured for their smaller molecular weight cutoff, and narrower pore size distribution which lead to higher divalent and multivalent ion rejection ability. Moreover, these membranes show better designability owing to their thin selective layer make-up and porous support with different chemical compositions. However, the interfacial polymerization (IP) rate of reaction is known to affect the permeability and selectivity of the TFC nanofiltration membranes by weakening the controllability of the selective layer structure. Therefore, this study was designed to improve the structural quality of the TFC nanofiltration membranes through surface and interface engineering, and subsequently, increase the functionality.
[the_sdg_impact] => It is one of the ambitions of the United Nations to ensure availability and sustainable management of water and sanitation for all (SDG 6: Clean water and sanitation). A report by the United Nations’ Water for Life initiative stated that one in four people do not have access to safe drinking water, and up to 50% of the global population are at risk of living in water stressed areas by 2025. With such concerns looming close, undoubtably, there is a demand for advanced and efficient wastewater treatment technology to be put in place. Thus, the successful designing of improved and highly functional TFC nanofiltration membranes through innovative approaches portrayed in this study could be the much-needed solution in addressing these issues.

[the_novelty] => This research designed polymersomes with inhomogeneous membranes capable of programmed drug release with accurate control by modifying the molecular architecture and photo-cross-linking degree of the polymer. The process involved introduced crystalline PCL moiety as part of the membrane’s molecular structure via the synthesis of three polymersomes with different hydrophobic chains, PEO43-b-P(CL45-stat-CTCL25), PEO43-b-P(CL108-stat-CTCL16), and PEO43-b-PCTCL4-b-PCL79. As a result of the amorphous PCTCL moieties in the membranes, high permeability with finely tunable drug release rate was achieved. A series of mesoscopic dynamics (MesoDyn) simulations and doxorubicin release tests affirmed that the membrane permeability is indeed related to the membrane phase separation of the polymersome. In conclusion, membrane phase separation technique used for the modification of polymersomes improved programmed drug release rate; thus, promising great significance in the field of drug delivery.
[the_background] => In the field of biomedicine, small molecules relied on membranes such as polymersomes as carriers for drug delivery. Thus, the effectiveness and efficiency of drug delivery become key focus points when considering treatment development for a range of diseases, including cancer. Despite being heavily researched and among the promising choice as drug delivery vessels, conventional polymersome membranes lack efficiency due to its homogeneity, making it harder for the drug to be released. This led to recent research centering their attentions in modifying and customizing polymersome membranes to allow programmed release of small molecular drugs to meet the demands of biomedical practices. As a continuation of past efforts, this research intends to overcome the challenge of high permeability of the PCTCL-based polymersomes caused by their amorphous nature, rendering it efficient to deliver small molecules for broader applications.
[the_sdg_impact] => As the global population continues to expand along with longevity, the importance and use of medicines are expected to increase. However, this will lead to a greater impact on the ecosystem and our health in the long term. Hence, there is a growing need to support precision medicine and to reduce ineffective medicine use which could burden patient, society and environment in the long run. The outcome of this research, the enhanced capability of programmed drug release via the modification of polymersomes, meets such demand. (SDG 3: Good health and well-being)

[the_novelty] => Based on the study, the Convolution Neural Network (CNN) model, which is a deep learning-based model optimized through the proposed methodology, can successfully detect COVID-19 cases and distinguish chest X-ray images of viral pneumonia patients and COVID-19 apart from healthy individuals. Two datasets of chest X-ray images consisting of normal, COVID-19 and viral pneumonia were used for training and testing the CNN model. The model was tested with dataset 1 and optimized through automatic tuning of hyper parameters. Then, dataset 2 was used to train and test the model with the parameters being constant from the previous testing. The results indicated that the proposed deep learning-based model showed 98% and 96% classification accuracy for datasets 1 and 2, respectively. However, further testing of the efficiency of the model should be carried out using a robust dataset consisting of images of various respiratory diseases.
[the_background] => The study is carried out to develop an optimized Convolution Neural Network (CNN) model that could be potentially used as an automated diagnostic tool for screening COVID-19 patients using chest X-ray scans. The study indicated that other diagnostic techniques designed using CNN showed limitations, such as the accuracy of the models in classifying COVID-19 was affected by the images used for training. This is because the changes in the image pixels caused by rotation and resize actions were not considered during the model's optimization procedure. As a result, the models fail to classify COVID-19 affected chest X-ray scans apart from normal and viral pneumonia chest X-ray scans. The proposed deep learning-based model aims to address the limitations demonstrated by previous deep learning-based models to increase the accuracy of COVID-19 detection.
[the_sdg_impact] => The COVID-19 outbreak, which was declared a global pandemic has resulted in a major global crisis and has taken more than 6 million lives worldwide as reported by World Health Organization (WHO). In the study, the optimized deep learning-based model is a potential diagnostic tool for COVID-19 detection due to its higher accuracy compared to existing gold standard diagnostic tools. The UN’s Sustainable Development Goal (SDG) strongly associated with the study is “Goal 3: Good Health and Well-Being”. The study is also linked with “Goal 9: Industry, Innovation and Infrastructure” as the innovation of using chest X-ray images to train and optimize a deep learning-based model can be used to replace the existing diagnostic tool and prevent any misclassification among patients.

[the_novelty] => In the study, the pre-trained model, VGG16, demonstrated the most consistent performance compared to other deep-learning-based models. This was concluded by the results that indicated the validation accuracy of VGG16 was 76.6% and 87.76% for CT and X-ray images, respectively. The study was conducted by training, testing, and validating several models with CT and X-ray images from COVID-19 and non-COVID-19 patients, followed by quantifying various parameters. In the study, the validation accuracy of Xception was the highest when trained with X-ray images, whereas the validation accuracy of VGG19 was highest when trained with CT images. Furthermore, the use of X-ray images for training has indicated better outcomes among models than CT images for training. However, further testing of the models with more epochs during training can improve the existing accuracy of the models. Moreover, larger datasets should be used to further improve the training of the models.
[the_background] => The reverse transcription-polymerase chain reaction (RT-PCR), the gold standard for COVID-19 detection, has drawbacks, such as false positive or false negative, and has an average accuracy rate of 63%. As a result, the study aimed to develop deep learning-based models as potential alternatives for existing COVID-19 diagnostic tools. The deep learning-based models are effective diagnostic tools due to the high accuracy in detecting COVID-19 patients based on radiological images. Moreover, deep learning techniques can identify underlying features in the radiological images, which contributes to the accuracy of diagnosis. In the study, the impact of using CT and X-ray images on the performance of models was compared for the first time as no previous studies carried out a comparative study between CT and X-ray images.
[the_sdg_impact] => The use of deep learning techniques with radiological images is a potential diagnostic tool due to its higher accuracy for COVID-19 detection as compared to the current gold standard of COVID-19 detection. The UN Sustainable Development Goal (SDG) addressed by this study is “Goal 3: Good Health and Well-Being”. The World Health Organization (WHO) declared the COVID-19 outbreak a global pandemic on 11 March 2020. A diagnostic tool with high accuracy is important for COVID-19 detection to prevent false identification among patients and help curb the spread of the disease. Another UN Sustainable Development Goal (SDG) strongly associated with the study is “Goal 9: Industry, Innovation and Infrastructure”. The outcome of this study can create a huge impact on the medical industry as the potential diagnostic tool can aid doctors and researchers in stopping the spread of the virus.

[research_footprints] => Shared transformational leadership; Team performance; Team reflexivity, Workplace spirituality
[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => For the first time, shared transformational leadership and workplace spirituality have been proven to be essential to higher team reflexivity. Besides, this study shows that both workplace spirituality and team reflexivity play an important role in mediating the relationship between shared transformational leadership and team performance. Meanwhile, workplace spirituality also mediates the relationship between shared transformational leadership and team reflexivity. 130 ongoing teams working in India’s information technology sector were involved in the data-collection process. The data on shared transformational leadership were collected by adopting the referent-shift consensus method. Since the impact of trust among team members is not considered, future research may examine the mediating influence of team trust in the relationship between shared transformational leadership and workplace spirituality.
[the_background] => In an organization, shared transformational leadership is valuable in building linkages between the team’s mission and the values of associates. The result is crucial in inspiring a shared vision, raising team members’ awareness of their team’s objectives, and creating a conducive space for reflection on the team’s work. Hence, this form of shared leadership could potentially be the main driving force behind team performance. Past studies imply that higher team reflexivity can be achieved by creating a sense of community among team members. This gives rise to the idea that workplace spirituality is an antecedent of team reflexivity. To date, the influence of workplace spirituality on team performance remains ambiguous. To fill up the existing knowledge gap, this study investigates the relationship between the constructs of shared transformational leadership and team performance. Furthermore, it examines the mediating roles of workplace spirituality and team reflexivity in various relationships involving shared transformational leadership. The outcomes are potential indicators for managerial staff to develop managing methods that emphasize shared transformational leadership and workplace spirituality.
[the_sdg_impact] => Team performance and effectiveness are the critical determinants for the success of a business unit. On the other hand, upholding team performance has been the main challenge not only for a team leader but also for the organization involved. This research managed to determine several factors that significantly influence team performance both directly and indirectly. By promoting the importance of decent management styles and a positive workplace for work performance., this research achieves UNSDG 8: Decent Work & Economic Growth.

[video] =>
[the_novelty] => This study provided theoretical insights on the impact of mandatory corporate social responsibility (CSR) on the costs of debt (COD) and equity (COE) of non-financial firms in India. It was determined that higher CSR leads to lower COD and higher COD. However, following the 2014 policy on mandatory CSR spending and reporting, findings indicated an increase in COD and COE. Unlike voluntary CSR, policy intervention in mandating CSR creates a negative signal among socially responsible investors, especially where the intention is of concern. As a whole, the outcome of the study contributes significantly to the extant literature in terms of policy intervention effects on the relationship between CSR, COD, and COE.
[the_background] => In 2014, India became the first nation to announce mandatory CSR legislation as an effort to boost philanthropic giving culture across all sectors. Past literature reported that firms with superior voluntary CSR performance, more often than not, gain favorable treatment in capital markets due to an optimistic investor attitude. However, active participation in CSR activities is not received in the same manner globally as investors in some countries may view CSR negatively. Moreover, making CSR mandatory could influence the nature and impact of signal intentionality on investors. Therefore, this study aims to understand the impact of policy intervention with regard to CSR performance and its relationship with COD and COE.
[the_sdg_impact] => Practicing corporate social responsibility (CSR) voluntarily incorporates economic, social, and environmental responsibilities into business operations to foster sustainable business growth while positively impacting the environment and the community. Clearly, mandating such practice across all business sectors would significantly impact the business and economic development. Therefore, the findings of this study could benefit economists and policymakers in understanding these impacts as well as further stimulate industry-driven R&D.

[figures] =>
[video] =>
[the_novelty] => In order to commercialize the high-temperature gas-cooled reactor pebble-bed module (HTR-PM) demonstration project, this study developed the HTR-PM600, i.e. a 600 MWe high temperature gas-cooled reactor nuclear power plant. With a nuclear island size that is comparable to a domestic pressurized water reactor (PWR) of the same power level, the HTR-PM600 comprises six reactors modules directly replicated from HTR-PM. All of the modules are connected to a single steam turbine. Notably, the six reactor modules are accommodated by a large circular ventilated low-pressure containment (VLPC) which lowers the overall volume of the reactor building, optimizes the arrangement of the steam and feedwater pipes, provides close references of industrial foundations as well as experiences from PWR nuclear power plants, and achieves improved capacity of radioactive retention. The safety features of HTR-PM600 are identical to those of the HTR-PM whereby each reactor module is physically independent and isolated by its own concrete cavity. In addition, six separated reactor cavity cooling system (RCCS) are placed on the outer surface of the upper part of the containment. With the adoption of proven technology from HTR-PM, reference to layout practices of the PWR, and improved efficiency as well as cost, the HTR-PM600 is an economically competitive Generation IV nuclear energy technology.
[the_background] => The remarkable pebble-bed high-temperature gas-cooled reactor (HTGR) invented by Professor R. Schulton has led to the materialization of the 45 MWt AVR pebble HTG experimental reactor and 750 MWt THTR HTGR demonstration power station. Meanwhile, the concept of a ‘modular’ HTGR technology with inherent safety features gave rise to the development of a 200 MWt modular pebble-bed HTGR (i.e. HTR-Module) which has not been constructed to date. Following the rapid advancement in HTGR technology, scientists in China have successfully developed the HTR-10 and HTR-PM (i.e. a 200 MWe pebble-bed modular HTGR nuclear power demonstration plant) in the 1990’s and 2000’s, respectively. The achievement of HTR-PM indicated the readiness for the commercialization phase. Therefore, the HTR-PM600, an enhanced version of HTR-PM, was planned and executed primarily for commercialization purpose. The triumphant implementation of HTR-PM600 marks a significant milestone in the global development of Generation IV nuclear power technology.
[the_sdg_impact] => Nuclear energy is the second-largest source of low-carbon electricity behind hydropower. The high-energy density of nuclear energy is essential in addressing the existing energy gap, implying the need for extensive research to develop an economically competitive nuclear energy technology. The materialization of HTR-PM600 paves a path to the implementation of commercial Generation IV nuclear power plants and, thus, this study realizes UNSDG 9: Industry, Innovation & Infrastructure.

[figures] =>
[video] =>
[the_novelty] => The state-of-the-art Shanghai Laser Electron Gamma Source (SLEGS) has officially completed its commissioning which lasted from July to December 2021. Other than a back-scattering mode, for the first time, a slant-scattering mode is adopted in the SLEGS beamline to generate powerful quasi-monoenergetic gamma-ray beams systematically. With an energy spread of 2 – 15 %, a gamma-ray beam with energy ranging from 0.25 to 21.1 MeV in slant-scattering at collision angles ranging from 20 – 160° is generated. In back-scattering at 180°, the beam achieves maximum energy of 21.7 MeV. Notably, a 2 % energy resolution can achieved with a 1-mm or smaller collimator. The SLEGS beamline primarily comprises four components: i) a 100-W CO2 laser and laser transport; ii) an interaction chamber (slant-scattering) and a multi-function chamber (back-scattering); iii) two-stage coarse and fine collimators and a gamma flux attenuator; and iv) an experimental hutch, an experimental detector, a gamma absorber, and a data acquisition system. In order to establish a more in-depth understanding of the energy resolution, more realistic Geant4 simulations can be deployed to carry out a thorough analysis in the future.
[the_background] => The laser Compton scattering (LCS) gamma source is currently the most advanced quasi-monoenergetic gamma-ray source supporting photonuclear physics research. Meanwhile, slant-scattering is an essential technology to produce gamma-ray beams with tunable energy at synchrotron radiation facilities which operate at fixed electron beam energy. Hence, in an attempt to establish a world-class high-energy laser electron gamma source, scientists in China have recently commissioned the Shanghai Laser Electron Gamma Source (SLEGS) which adopt both slant- and back-scattering mode to yield MeV gamma-ray beams. By doing so, a new milestone has been achieved by the Shanghai Synchrotron Radiation Facility (SSRF) for having a total of 16 beamline stations in its Phase II Project. With the readiness of SLEGS in facilitating both basic and applied research in nuclear physics, scientists will have more space and opportunity to contribute to the advance of the nation’s nuclear technology.
[the_sdg_impact] => To-date, the number of facilities with high-energy laser electron gamma sources dedicated to nuclear science studies remains scanty globally. Since SLEGS is a high-potential multi-functional experimental platform, the addition of SLEGS to the Shanghai Synchrotron Radiation Facility will be of significant impact to the expansion of nuclear research, especially in China. By supporting the advancement of nuclear technology, this study shows good alignment with United Nations Sustainable Development Group (UNSDG) 9: Industry, innovation & infrastructure.

[the_novelty] => By implementing the 24-h urine creatinine excretion rate (U-CER) adjustment method, this study has successfully eliminated the paradoxical mortality in patients with high estimated glomerular filtration rate (eGFR). In other words, the 24-h U-CER–adjusted eGFR allowed a more accurate evaluation of mortality risk. The inclusion of muscle mass in the estimations was able to correct the bias. These results also served as the first empirical evidence proving the impact of sarcopenia on the paradoxical mortality pattern in the patients. For validation, future study may examine the effectiveness of this approach by implementing it in different ethnic populations and health care systems. Moreover, the feasibility of 24-h U-CER in monitoring excessive muscle loss over the course of chronic kidney disease (CKD) should be investigated in the future.
[the_background] => The GFR indicates how much blood our kidneys clean every minute based on our body size. The methods to evaluate GFR include measured glomerular filtration rate (mGFR), estimated glomerular filtration rate (eGFR), and 24-h creatinine clearance (CrCl). Although mGFR is known to be the gold standard for measuring kidney function, it is costly and inefficient. Meanwhile, 24-h creatinine clearance (CrCl) faces several setbacks, such as inaccurate estimation of GFR and being inconvenient, even though it has higher applicability for patients with sarcopenia or malnutrition. Estimated GFR (eGFR) based on equations (i.e. Modification of Diet in Renal Disease [MDRD] and Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) have shown discrepancies and low feasibility. Moreover, a paradoxically increased risk of mortality was also reported. Nonetheless, the calculation of eGFR based on CKD-EPI is recognized as a good practice since 2012. Despite having various locally-derived eGFR equations, they are not systematically compared with 24-h CrCl-adjusted equation-based eGFR in terms of mortality prediction. Moreover, since decreased muscle mass is the main factor giving rise to the high eGFR–high mortality paradox, the 24-h urine creatinine excretion rate (24-h U-CER) (i.e. a 24-h CrCl method) is suitable for adjusting the equation-based eGFR for its effectiveness in measuring muscle mass. Therefore, this study compared the performance of equation methods for predicting 5-year all-cause mortality by applying 24-h CrCl, equation-based eGFRs, and 24-h U-CER. The reversal of paradoxically high mortality achieved by applying 24-h U-CER is a significant milestone towards more accurate kidney diagnosis.
[the_sdg_impact] => 10% of the global population is affected by CKD. Thus, a technique for high-precision eGFR is crucial for early diagnosis and treatment of CKD. The 24-h U-CER–adjusted eGFR developed by this study exhibits high accuracy in mortality risk evaluation and, more importantly, it is ready to be adopted by health care systems. By contributing to the enhancement of health care, this study shows good alignment with UNSDG 3: Good Health & Well-Being.

[the_novelty] => Upon identifying two complex crystal structures of bacterial STING/c-di-GMP, this study reveals the precise binding mode of c-di-GMP to the bacterial STING. The findings clarify how bacterial STING differentiates c-di-GMP second messengers from other cyclic dinucleotides during viral infections. Besides that, the interaction between bacterial STING and c-di-GMP is found to be accountable for the oligomerization of the former into long filament. According to the oligomerization mechanism and ligand specificity, the bacterial STING is categorized into Class I and II. Since mammalian STING protein originated in bacteria, the output of this study provides valuable insights in the innate immunity of human.
[the_background] => Stimulator of interferon gene (STING) is a crucial immune sensor which, during viral infection, triggers self-destruction of infected cells in order to contain the infection. Although the signaling pathway is initiated by the binding between STING and c-di-GMP, the exact binding mode of c-di-GMP to bacterial STING and the specific recognition mechanism remain vague. Thus, this study is carried out to investigate the mechanism by determining the crystal structures of bacterial STING/c-di-GMP. It also proposes that Class II bacterial STING, which recognizes 3’3’-cGAMP more favorably, is in the evolutionary transition from c-di-GMP-dependent signaling in bacteria to 2’3’-cGAMP-dependent signaling in eukaryotes. Other than facilitating future STING-related studies, this research complements the existing knowledge base for human’s innate immune signaling.
[the_sdg_impact] => STING plays an important role in innate immunity as an essential mediator and inducer. Thus, to speed up the advance of research related to human immune system, a more in-depth understanding of mammalian STING protein (which originated in bacteria) is required. By shedding light on the crucial mechanisms involved in human immune system, this study fulfils UNSDG 3: Good Health & Well-Being.

[the_novelty] => This study discovered the potential of exosomal membrane-bound PD-1 (Exo-PD-1) in enhancing the cytotoxic activity of T cells against tumor cells and, simultaneously, attenuating immune suppression in triple-negative breast cancer (TNBC). Upon activation, Exo-PD-1 released by T cells were actively involved in two modes of PD-L1-blockade anti-tumor action, i.e. remotely binding to exosomal PD-L1 and directly binding to PD-L1 on tumor-cell surface. The Exo-PD-1 binding on the tumor-cell surface induced clathrin-mediated endocytosis (CME) of PD-L1. Other than creating an entry point for Exo-PD-1 to enter the TNBC cells, CME of PD-L1 also reduced the amount of surface PD-L1 available during subsequent direct interaction between T cells and tumor cells. The protective role of Exo-PD-1 against the anti-tumor immune dysfunction induced by PD-L1 in TNBC has been confirmed by in vitro and in vivo studies. As part of the expansion of research scope, future studies ought to examine whether the tumor-infiltrating lymphocytes (TILs) markers of T cell apoptosis and exhaustion are contained by T cell-derived exosomes, and whether they bear similar immune function to that of Exo-PD-1 in fighting tumor.
[the_background] => Programmed cell death protein 1 (PD-1) is a protein on the surface of T and B cells. Although PD-1 is essential in preventing autoimmune diseases, it also prevents cancer cells from being killed. In contrast, the expression of PD-1 showed positive correlation to the survival rate of patients with triple-negative breast cancer (TNBC). These contradicting yet intriguing observations made scientists wondered if the PD-1 on T cells comprises uncovered potential associated to the inhibition of cancer cells. Meanwhile, past studies also reported that exosomes derived from T lymphocytes were involved in the regulation of immune reaction. Upon investigating the role of T cells-derived exosomes in suppressing TNBC, this research elucidated how exosomal PD-1 protects against the anti-tumor immune dysfunction induced by PD-L1 in TNBC. Notably, this discovery may lead to the development of therapeutic strategies which enhance cytotoxic activity against tumor cells and attenuate immune suppression simultaneously.
[the_sdg_impact] => As long as cancers exist, 10 million lives are lost globally each year and this number can be lowered only by more effective therapeutic strategies. With the proven potential of Exo-PD-1 in treating triple-negative breast cancer (TNBC), promising cancer therapies can be developed based on the modification of exosome surface. Moreover, the discovery of this study also proves the importance of immune suppression attenuation in fighting cancers (UNSDG 3: Good Health & Well-Being).

[the_novelty] => This study reported the pathway underlying how melatonin suppresses the metastatic potential of osteoblastic prostate cancer. The pathway started with the binding of melatonin to MT1 receptor which was crucial in conveying the downstream effects of melatonin. After that, the phosphorylation of FAK, c‐Src and NF‐κB was decreased, inhibiting the integrin α2β1 expression as well as osteoblastic prostate cancer migration. The pathway was revealed via in vitro studies using osteoblastic prostate cancer cell line C4‐2. Preclinical trials can be carried out in the future to explore the possibilities of developing a cancer therapy based on this discovery.
[the_background] => Prostate cancer has been identified as a cause of osteoblastic bone metastasis. This indicated that patients with prostate cancer are also facing a high risk of metastatic bone disease. Meanwhile, strong evidence implied the direct involvement of receptors integrins α2β1 in prostate cancer bone metastasis due to their potential in prostate cancer cell progression, migration, and invasion. On the other hand, besides exhibiting antitumor activity, melatonin was actively involved in antimetastatic activity in osteolytic prostate cancer cells as well as osteoclastogenesis inhibition. However, the potential and mechanism of melatonin in inhibiting the migratory and invasive properties of osteoblastic prostate cancer cells remain ambiguous. Thus, this study aimed to investigate the underlying mechanism of how melatonin hinders the motility human prostate cancer cells and the metastatic in osteoblastic prostate cancer cells. The findings confirmed the therapeutic potential of melatonin for prostate cancer bone metastases, paving a path to the design of high-efficacy therapeutic strategies.
[the_sdg_impact] => Metastatic bone disease is a severe collateral damage due to cancers and 84% of deaths were due to prostate cancer. There are approximately 268,000 new cases of prostate cancer reported yearly in United States, indicating the high risks of metastatic bone disease. Hence, while focusing on cancer therapies, attention should also be allocated to the treatment of metastatic bone. By demonstrating the efficacy of melatonin in inhibiting the metastatic potential of osteoblastic prostate cancer, this study fulfils UNSDG 3: Good Health & Well-Being.

[the_novelty] => Based on a cohort of 105,184 participants, this study disclosed the underlying mechanisms of the comorbidity between psychiatric disorders and type 2 diabetes. A family history of type 2 diabetes was associated with family history of all three common psychiatric disorders i.e. schizophrenia (SCZ), major depressive disorder (MDD) and bipolar disorder (BPD). Compared to paternal type 2 diabetes, maternal type 2 diabetes demonstrated a higher strength of association with SCZ family history, indicating that women demonstrate a more predominant effect of family history of type 2 diabetes on SCZ than men. Higher genetic loading for SCZ was associated with a lower risk of type 2 diabetes in women but not in men. This suggests that gender could potentially alter the genetic effect on human diseases. On the other hand, higher genetic loading for MDD was associated with a higher risk of type 2 diabetes. Although familial aggregation was reported between type 2 diabetes and BPD, there is a lack of a polygenic association between them probably due to a role of environmental factors in the mechanisms. Results also showed that the polygenic effect of SCZ on type 2 diabetes may be partly mediated by obesity and the polygenic effect of MDD on type 2 diabetes may be partly mediated by obesity or smoking. Future studies may replicate this approach on participants of other ancestries (besides Taiwanese) to explore the outcomes.
[the_background] => The comorbidity between psychiatric disorders and type 2 diabetes has been proven and this implied the importance to examine its underlying mechanism. Moreover, the familial aggregation of type 2 diabetes and common psychiatric disorders also suggested an influence of shared environmental factors or genetic background. Further studies showed that the association was mainly due to genetic background, especially in female. Meanwhile, the influence of sex differences was highlighted through the difference in prevalence of type 2 diabetes in the mothers and fathers of those with psychosis. Hence, this study investigated the underlying mechanisms of the comorbidity between psychiatric disorders and type 2 diabetes by examining familial aggregation and testing for polygenic overlap based on a molecular approach. For the first time, polygenic loading was applied for common psychiatric disorders to predict type 2 diabetes in Asia with the largest sample size to-date. The output provides crucial insights indicating the needs for therapies and preventive plans to address the initial development of type 2 diabetes and its comorbidity with psychiatric disorders.
[the_sdg_impact] => Comorbidity is associated with degrading health, higher complexity clinical management, and higher health care costs. Based on the proven comorbidity between psychiatric disorders and type 2 diabetes, depression should be diagnosed and treated proactively as the physical complications of diabetes that are commonly prioritized. This will directly lower the number of cases for both depression and type 2 diabetes. By understanding the underlying mechanisms of the comorbidity, high-efficacy therapeutic strategies can be planned to lower the risks for both diseases (UNSDG 3: Good Health & Well-Being).

[the_novelty] => Via in vitro and in vivo studies, this study discloses the underlying mechanism of DNA double-strand break (DSB) repair carried out by MRE11/RAD50/NBS1 (MRN) complex interacting protein (MRNIP). In intrinsically disordered region, the MRNIP forms condensates which then concentrates MRN complex into liquid-like droplets. When DSBs are formed and sensed, the MRNIP condensates proceed swiftly to the damaged DNA and promote the binding of damaged DNA to the concentrated MRN complex. This results in the autophosphorylation of ataxia telangiectasia mutated (ATM) followed by an accelerated DNA damage response and DSB end resection, promoting the homologous recombination (HR)-mediated DSB repair. Meanwhile, compared to normal rectum tissues, lower MRNIP expression is observed in radiation proctitis tissues. This implies that targeting MRNIP condensates could help to sensitize tumor cells to radiotherapy and lead to the development of radiation proctitis. In order to complement the existing findings, the authors are looking forward to the direct uncovering of the pathway underlying the impact of MRNIP condensates on MRN-mediated DSB sensing.
[the_background] => The repair of DNA double-strand breaks (DSBs) is no doubt a critical process to maintain the sustainability of organisms. Defective DSBs repair is very likely to cause devastating consequences such as cancer, embryonic death, and neurological disorders. In DSBs repair, the MRE11/RAD50/NBS1 (MRN) complex acts as a sensor towards DSBs and also an initiator of DNA damage responses. However, when DSBs is formed, it is still elusive with regards to how the MRN complex senses and binds to DNA rapidly. In the mean time, liquid-liquid phase separation (LLPS) is a process whereby molecules condense into a dense phase (high concentrated liquid droplets) whilst the remaining solution forms a dilute phase. Various studies associated LLPS to the repair of DNA damage and this indicated that LLPS might play a crucial role in DSBs repair. Therefore, an international collaboration with Sun Yat-sen University Cancer Center (China) and Sun Yat-sen University (China) took place to conduct an in-depth investigation on the role of MRNIP condensate in regulating HR-mediated DSB repair as well as the impact of LLPS on the function of MRNIP. The output of this study is an essential reference for future research which target to overcome diseases related to defective DSBs repairs.
[the_sdg_impact] => DNA DSBs, the most severe type of DNA damage, leads to apoptosis, gene mutation, and carcinogenesis if left unattended. As an effort to overcome defective DNA DSBs repair, a strong fundamental understanding about the relevant underlying mechanisms must be acquired. The pathway unveiled in this study provides significant insights on the pathway of DSBs repair and, thus, this study is very well-aligned with UNSDG 3: Good Health & Well-Being.

[the_novelty] => This study reveals the signaling pathway underlying how pridopidine acts as an agonist in promoting autophagy for neuron protection. When a motor neuron is under pathological threats, pridopidine dissociates chaperone protein SIGMAR1 from HSPA5, allowing SIGMAR1 to proceed to the nuclear pore to chaperone nucleoporin POM121. Then, POM121 recruits KPNB1 so as to create an effective in-bound transportation of TFEB (from cytosol into nucleus), which is crucial for the initiation of autophagy. For the first time, the impact of SIGMAR1 agonists and antagonists on the chaperone activity of SIGMAR1 is elucidated, proving that the SIGMAR1 is a ligand-regulated chaperone. Results indicate that, with the presence of chaperone, the structural nucleoporin POM121 also serves as a signaling molecule which enables TFEB-mediated autophagy. Notably, pridopidine is able to effectively protect motor neuron NSC34 against H2O2-induced toxicity expressing the pathogenic (G4C2)288 repeat. In the absence of pridopidine in transfected NSC34 motor neuron, hexanucleotide (G4C2)RNA expansion (HRE) disrupts TFEB transport by hindering the interaction between SIGMAR1 and POM121. By complementing these discoveries with the ongoing clinical development of pridopidine, future studies may focus on designing a higher-efficacy therapy to treat neurodegenerative diseases.
[the_background] => Neurodegenerative diseases, such as Alzheimer’s disease (AD) and amyotrophic lateral sclerosis (ALS), are closely related to impairments in autophagy. In ALS-frontotemporal lobar degeneration (ALS-FTD), autophagy is disrupted due to the defective transportation of transcription factor TFEB from the cytosol into the nucleus. Hexanucleotide (G4C2)RNA expansion (HRE) is accountable for the impairment but the exact molecular pathway involved has not been reported yet. Meanwhile, although the chaperone protein SIGMAR1 plays a pivotal role in autophagy, the underlying mechanism was ambiguous. Thus, this research aims to answer these uncertainties and also to examine the mechanism underlying the neuroprotective effect of pridopidine. The study outcome indicates that, by targeting the SIGMAR1, a pharmacological approach could potentially be designed to overcome diseases related to autophagy impairment.
[the_sdg_impact] => Millions of people suffer from neurodegenerative diseases globally. In United States, approximately 6 million and 1 million people are reported to be the victims of Alzheimer’s disease and Parkinson’s disease, respectively. These alarming figures can possibly be reduced by therapies which target the chaperone protein SIGMAR1. By explaining how pridopidine activates SIGMAR1, this research paves a clear direction which facilitates the development of therapies to treat neurodegenerative diseases (UNSDG 3: Good Health & Well-Being).

[graphic_abstract] =>

[video] =>
[the_novelty] => This study reports a novel signalling pathway which converts IL-17-producing CD8+ T cells (Tc17) to IFN-γ producers, leading to enhanced antitumour activity and cytotoxicity of Tc17 cells. The pathway is initiated by IL-4 followed by PI3K/AKT signalling which induces the expression of Eomes and upregulates T-cell receptor-associated transmembrane adaptor 1 (TRAT1) in Tc17 cells. The upregulation of TRAT1 then promotes IL-4-induced T-cell receptor (TCR) stabilization and Tc17 cytotoxicity. IL-4, besides acting as an inducer, is capable of promoting Tc17 cells expansion to achieve higher antitumour potential. On top of these findings, a novel ex vivo procedure is proposed to reprogramme Tc17 extracted from human peripheral blood mononuclear cells (PBMC) in order to be applied in adoptive cell therapy (ACT) for cancer patients. By having enhanced cytotoxicity, the novel ACT could potentially treat a wide spectrum of cancers.
[the_background] => Immune effector cell (IEC) therapy primarily involves the use of one’s immune system to treat cancer in his/her own body. Despite its proven potential, there is a huge room for development as the recently applied IEC strategies induce acute but short responses. IL-17-producing CD8+ T cells (Tc17) has been identified as a promising candidate for IEC therapy for its ability to be reprogrammed as cytotoxic anti-tumour effectors. However, Tc17-based IEC is yet to be ready due to the limited knowledge on the factors affecting Tc17 reprogramming and the mechanisms underlying its cytotoxicity promotion. Thus, upon discovering the answers to these uncertainties, this study has taken extra miles to establish a feasible procedure to expand Tc17 from peripheral blood of cancer patients. The research outcome creates a profound impact in oncology by enhancing the applicability and efficacy of Tc17-based IEC therapy.
[the_sdg_impact] => With more than 100 types of cancer reported, the continuous development of immunotherapy is crucial to uphold the survival rate of cancer patients. The discovery of a potent Tc17-based adoptive cell therapy (ACT) serves not only as a possible cure, but also as robust knowledge base for future research. By disclosing the signalling pathway involved, this study facilitates the development of new cancer therapies (UNSDG 3: Good Health & Well-Being).

[graphic_abstract] =>

[video] =>
[the_novelty] => This study provides strong evidence that glucose metabolic re-wiring may contribute to the development of acquired resistance of non-small cell lung cancer (NSCLC) to epidermal growth factor receptors tyrosine kinase inhibitor (EGFR TKIs). The findings suggest that NSCLC cells with acquired EGFR TKI resistance are more tolerant to low glucose-induced autophagy following a metabolic shift to higher glucose uptake and glycolysis activity due to upregulation of active sodium/glucose co-transporter 1 (SGLT1) by Thr678-phosphorylated EGFR, in a protein kinase C delta (PKCδ)- dependent manner. Therefore, the combination of SGLT1 inhibitor with EGFR TKIs shows a synergetic effect in reducing tumor growth and glucose uptake in vitro and in vivo. Future studies can be conducted to determine if hormone receptors are involved in the regulation of SGLT1 expression in lung cancer tissues.
[the_background] => EGFR, a membrane-bound tyrosine kinase receptor, has been found to be a critical oncogene in promoting tumorigenesis, mitogenesis, and tumor progression of various cancer types, including NSCLC. Small molecule tyrosine kinase inhibitors (TKIs) targeting the ATP-binding pocket of the EGFR kinase domain were developed and approved for NSCLCs. However, the secondary EGFR mutations and activations of alternative receptor tyrosine kinases (RTKs) created a bypass track, leading to the failed responses to EGFR TKIs, yet fail to fully account for the development of acquired resistance to these drugs in NSCLC patients. Mounting evidence has proved that EGFR impacts the rewiring of the glucose metabolic network to promote tumor progression in NSCLC. Therefore, this study aims to understand the glucose metabolic re-wiring pathway in NSCLC patients with acquired EGFR TKI resistance. The findings would potentially be used to explore an effective treatment strategy against EGFR TKI resistance.
[the_sdg_impact] => Approximately 85% of lung cancers are recognized as NSCLC. Mutations lead to EGFR amplification and overexpression and have been associated with NSCLC progression. Inhibitors targeting EGFR tyrosine kinase activity were used to block the downstream signaling pathway and showed promising therapeutic efficacy. Unfortunately, most patients with NSCLC who are treated with these drugs develop resistance. Much evidence has proved that EGFR promotes tumor progression by rewiring glucose metabolic networks in NSCLC. By identifying the biological mechanisms that associate glucose metabolic re-writing pathway with NSCLC treatment resistance, this study expands the possibility of increasing the effectiveness of the existing treatment. Ultimately, the proposed combination of SGLT1 inhibitor with EGFR TKIs would serve as a new therapeutic strategy to reduce the mortality rate of patients with NSCLC (UNSDG 3: Good Health & Well-Being).

[the_novelty] => This study unveils an immunotherapeutic approach to treat cancer by avoiding the phosphorylation of programmed cell death ligand 1 (PD-L1) through casein kinase 2 (CK2) inhibition. The inhibition of CK2 leads to degradation of PD-L1 in cancer and dendritic cells (DCs) followed by the activation of T cells by DCs which, in turn, enhances the antitumor activity. In other words, CK2 hinders the antigen-specific T-cell function through phosphorylation of PD-L1. Meanwhile, in preclinical trial, mouse mammary tumor exhibits suppressed growth when treated by a CK2 inhibitor combined with an antibody against T-cell immunoglobulin mucin-3 (Tim-3). Collectively, the outcome indicates that the approach is not only effective on triple-negative-breast-cancer (TNBC), but also applicable for other cancer types, such as lung cancer, prostate cancer, and melanoma. In order to validate this approach, future clinical studies can be conducted to focus on its anti-tumor efficacy in different types of cancer tissues.
[the_background] => Casein kinase 2 (CK2) has been proven to be a potential target in treating cancers. Although CK2 is crucial for cell sustainability, its upregulation in all cancers has shown consistent trend in promoting tumor cell growth, leading to poor prognosis. During the inhibition of CK2, significant improvement was observed in the antitumor activity of immune checkpoint receptor blockade using anti–CTLA-4 antibody. This suggests that CK2 inhibition could potentially overcome the ineffectiveness of anti–PD-1/PD-L1 immune checkpoint blockade (ICB) treatment experienced by a substantial amount of cancer patients. Hence, in an international collaboration with the Department of Molecular and Cellular Oncology from The University of Texas MD Anderson Cancer Center (USA), this study aims to investigate the mechanism of PD-L-1 regulation by CK2 and have successfully demonstrated CK2–PD-L1 pathway blockage as a high potential tumor treatment. Since this approach is applicable for various cancer types, it is likely to increase the chances for human to survive cancers.
[the_sdg_impact] => Cancer-related researches have been progressing dramatically but many of the potential therapies are effective to only limited types of cancer and patients. Since CK2 inhibition is a high-potential treatment for multiple cancer types, it can be coupled with other effective therapies to achieve better outcome. The output of this study creates a significant milestone in cancers treatment, realizing UNSDG 3: Good Health & Well-Being.

[the_novelty] => In an international collaboration with the Department of Experimental Radiation Oncology from The University of Texas MD Anderson Cancer Center (USA), this study discovers that glucocorticoid receptor (GR) is a promising target for overcoming pancreatic cancer. Based on animal trials, GR inhibition results in downregulation of programmed death-ligand 1 (PD-L1) and upregulation of major histocompatibility complex class I (MHC-I) in tumor cells. These effects then improve both anti-tumor immunity and response to immune checkpoint blockade (ICB) therapy. Consistent outcomes are also observed in patients with pancreatic ductal adenocarcinoma (PDAC). Meanwhile, clinical GR antagonist mifepristone is able to produce similar results although its anti-tumor effect is not as profound as that of GR inhibition. Nonetheless, the efficacy of the combined therapy of GR inhibition and mifepristone is worth to be tested clinically. In order to move towards materialization, future studies should focus on several scopes including: to determine whether targeting GR sensitizes pancreatic cancer to chemotherapies through immune regulation, to investigate the outcome of applying the same therapy on other types of cancer, and to optimize the dosage of GR antagonist mifepristone so as to enhance its efficacy with minimum toxicity.
[the_background] => To date, an effective treatment for pancreatic cancer has yet to be developed. Although chemotherapy and radiotherapy are the common therapies being used to treat patients of pancreatic cancer, they are very likely to cause severe deterioration in patients. Furthermore, major driver genes for pancreatic cancer (e.g. KRAS, TP53, CDKN2A, and SMAD4) have not been approved by FDA to be applied as clinical therapies yet. Despite showing positive effects on other cancer types, immune checkpoint blockade (ICB) therapies were not effective for pancreatic cancer, regardless of whether being applied alone or combined with other therapies (i.e. chemotherapy, radiotherapy, targeted therapy, and vaccination). Glucocorticoid receptor (GR) is the receptor to which cortisol and other glucocorticoids bind. The GR is expressed in almost every cell in the body and regulates genes controlling the development, metabolism, and immune response. Since the anti-tumor potential of GR has been demonstrated in past research, this study examines how GR can be part of the strategy to overcome pancreatic cancer. The output of this study show that GR inhibition is effective in treating pancreatic cancer and a feasible therapy can be derived based on that.
[the_sdg_impact] => Pancreatic cancer is projected to become the second leading cause of cancer-related death by 2030. Pancreatic ductal adenocarcinoma (PDAC) patients in the United States show a 5-year survival rate of as low as 6%. These alarming figures imply the urgent need for more effective therapies. As there is a huge room of improvement for the existing therapies of pancreatic cancer, the findings of this study are essential for the development of relevant therapies. By identifying GR as a target, this research contributes to the realization of breakthrough strategies to treat PDAC patients (UNSDG 3: Good Health & Well-being).

[the_novelty] => To better understand microsatellite-instable (MSI) tumours as a key to overcoming colorectal cancers (CRCs), this study shows that the inhibition of protein phosphatase 2A (PP2A) could lead to the loss of DNA mismatch repair (MMR) genes (i.e. causing MMRd), resulting in the conversion of microsatellite-stable (MSS) into MSI tumours. The PP2A inhibition brings about the conversion via two different pathways, i.e. by increasing retinoblastoma protein phosphorylation and by increasing histone deacetylase (HDAC)2 phosphorylation. Moreover, the inactivation of PP2A also enhances MSI tumours’ response to immune checkpoint blockade (ICB). In short, PP2A inhibition initiates neoantigen production, increases cytotoxic T cell infiltration and improves response to ICB. These results were obtained from animal models as well as human cancer cell lines and tissue array. In order to materialise an effective therapy based on the findings, future studies should investigate the effect of mRNA dysregulation or mutations of the genes on the adaptive and acquired resistance to ICB.
[the_background] => 15% of sporadic colorectal cancers (CRCs) are closely associated to microsatellite-instable (MSI) tumours with defective DNA mismatch repair (MMR). Compared to microsatellite-stable (MSS) tumours, focusing on the mechanism of MSI tumours development is a more practical strategy as MSI tumours exhibit better prognosis and response to immune checkpoint blockade (ICB) (i.e. a type of immunotherapy drug). Studies show that both CRC and non-CRC patients with MMR deficiency (MMRd) have better responses to programmed death 1 (PD-1) ICB therapy. These findings support the need to focus on MSI tumours even though the molecular mechanisms have yet to be confirmed. Meanwhile, although protein phosphatase 2A (PP2A)-targeted anti-tumour therapies have received significant attention, the anti-tumour effects of activating or inhibiting PP2A activity is uncertain. Furthermore, the number of studies on PP2A’s tumour-intrinsic signaling and response to ICB are still scanty. Therefore, this research aims to achieve two goals, i.e. to investigate the mechanism of MMRd and to examine the effect of PP2A inhibition on the conversion of MSS to MSI tumours. Other than solving the previously unanswered questions, the output of this study provides valuable insights to the possible feasible ways to overcome cancers by focusing on PP2A.
[the_sdg_impact] => In 2020, CRC was the second most common cause of cancer death worldwide, causing almost 1 million deaths. It was the third most common cancer in men but the second most common cancer in women, after breast cancer. The in-depth discussion on the potential of PP2A inhibition in fighting CRC opens up an avenue for the realisation of new treatments for CRC. With better knowledge base and more effective therapy, tremendous amount of CRC patients with will stand higher chance to survive (UNSDG 3: Good Health & Well-being).

[the_novelty] => As part of the effort to develop an effective therapy for liver cancer hepatocellular carcinoma (HCC), this study revealed the role of poly (ADP-ribose) glycohydrolase (PARG) enzyme in the development of HCC. PARG acted as a main culprit for the spread of HCC through the newly discovered PARG/DDB1/c-Myc signaling pathway which implies PARG as a potential biomarker for HCC treatment. More importantly, when PARG was inhibited, improved condition was observed in mice undergoing anti-PD-1 anticancer drug therapy. The results indicate that the inhibition of both PARG and PD-1 is a highly-effective dual-action therapy for HCC. With the promising output, future clinical trials can be conducted to determine and to optimize the efficacy of the dual-action therapy.
[the_background] => Despite being actively involved in various cellular activities (e.g. DNA replication, transcription, and apoptosis), PARG was also reported to cause tumor growth. Furthermore, positive outcomes were observed when PARG-targeted strategy was implemented in cancer therapies. All this led to unanswered questions related to the exact regulatory mechanism of PARG especially in the growth of cancer tissues. Hence, an international collaboration with the Department of Liver Surgery and Transplantation of Fudan University (Shanghai) took place to examine the physiological roles and signaling pathway of PARG in HCC progression. Co-inhibition of PARG and PD-1 was reported for the first time as an effective dual-action strategy for patients with HCC. These findings showed that other combination strategies involving PARG inhibition could possibly lead to effective treatment for other types of cancer.
[the_sdg_impact] => Within the wide spectrum of cancer, hepatocellular carcinoma (HCC) alone has caused more than 600,000 deaths each year globally. Since both chemotherapy and radiotherapy often cause relapse in patients, immunotherapy via PARG-inhibition could potentially minimize the side-effects while increasing the chance for recovery. Thus, this study contributes to the fulfilment of UNSDG 3: Good Health & Well-being by sharing profound discoveries in the research and development of cancer therapies.

[the_novelty] => In the context of religious tourism destinations, this study elucidated that the effect of visitors’ place attachment on destination loyalty is given rise by their on-site emotional experience (a mediator). Meanwhile, the extent of visitors’ religious affiliation (a moderator) determined how much place attachment and emotional experience would affect destination loyalty. Place dependence (a dimension of place attachment) showed an indirect effect on destination loyalty via emotional experience. In comparison to Hindu and Muslim visitors, this effect (moderated by religious affiliation) was strongest among Christian visitors. The data used in this study was obtained from a survey that involved 812 Attur Feast attendees, followed by a series of multiple regression analyses. Future studies may test the consistency of this experimental model by replicating it in contexts involving different religions. In addition, more dimensions of place attachment (e.g., place effect and place social bonding), extra psychological concepts (e.g., emotions and perceived authenticity), and reputation of religious destination can be included as part of the research.
[the_background] => Religious festivals are valuable occasions as they embrace customs and beliefs. Most of the festivals are being held at unique locations, fostering a sense of place attachment in the attendees. In turn, place attachment was shown to result in the development of emotional experience. However, an inadequate amount of studies have looked into the effect of place attachment on emotional experience and how this relationship leads to destination loyalty. Besides that, the effect of religious affiliation on those relationships has not been assessed yet. In order to complement the research gap, this study evaluated the role of visitors' place attachment and emotional experience on destination loyalty, with religious affiliation as a moderator within the model. The contribution of the outcome includes facilitating the planning for sustainability of religious events and providing constructive strategies to promote religious festivals and events.
[the_sdg_impact] => In 2019, India’s Travel & Tourism GDP contribution grew by 4.9%, the third highest after China and the Philippines. In the following year, it created 31.8 million jobs which contributed to 7.3% of the total employment in the country (source: ibef.org). These data indicate that tourism plays a major role in the livelihood of the people in India. Hence, the government should prioritize the industry by implementing policies to support and enhance tourism. This research sheds light on the influence of emotional experiences and religious affiliation on destination loyalty. Thus, its goal is perfectly aligned with UNSDG8: Decent Work & Economic Growth.

[the_novelty] => What keeps a visitor returning to a festival or tourist destination? In the context of a religious festival, this study demonstrated that visitors’ place attachment is a determinant for destination loyalty and emotional solidarity. Moreover, destination loyalty is positively affected by emotional solidarity. Place attachment also positively affected destination loyalty through emotional solidarity (a mediator). The strength of such effect relied on the visitor level of perceived safety (a moderator) at the festivals. The data collection and sampling involved 813 visitors during the Attur Church Fest in Karkala, India. Structural Equation Modelling (SEM) was used to test the hypotheses. The mediation and moderated mediation effects between the study constructs were tested using Process Macro 4.0. In order to go more in-depth, future studies can include obligatory religious motivations, shared behavior, and shared beliefs as antecedents of destination loyalty and emotional solidarity in a religious context. Furthermore, the influence of visitors’ perceived level of safety in the effect of antecedents on destination loyalty should also be emphasized. Destination managers should promote these festivals as an encounter momentum between host and guest and a sharing space of religious experiences that amplify the authenticity of the place. Publicising these aspects will definitely enhance the footfall (national and international) which in turn is beneficial to increase tourism potential of the region.
[the_background] => During religious festivals, place attachment is closely related to emotional solidarity (the degree of closeness between residents and tourists in a destination). Meanwhile, on-spot safety is a critical reason tourists return to the festivals. Although emotional solidarity contributes to a sense of safety, it remains obscure whether perceived safety may moderate the effect between place attachment and destination loyalty via emotional solidarity. Besides that, the effect of place attachment and emotional solidarity on destination loyalty is not investigated. To address the literature gap, this study disclosed how place attachment and emotional solidarity could influence destination loyalty and how perceived safety may moderate these relationships. The outcomes of this research serve as important guidelines for local authorities and festival organizers to implement necessary improvements to retain the loyalty of tourists and attendees.
[the_sdg_impact] => In 2020, the GDP contribution of the Indian travel & tourism industry was US$ 121.9 billion. Also, it accounted for 31.8 million jobs, which was 7.3% of the total employment in the country (source: ibef.org). These significant figures indicate that the Indian government should pay attention to enhancing and innovating the industry. By highlighting important theories that can promote development-oriented policies in supporting sustainable tourism, this study materialized UNSDG 8: Decent Work & Economic Growth. In the 2030 Agenda for Sustainable Development SDG target 8.9, aims to “by 2030, devise and implement policies to promote sustainable tourism that creates jobs and promotes local culture and products”. The importance of sustainable tourism is also highlighted in SDG target 12.b. which aims to “develop and implement tools to monitor sustainable development impacts for sustainable tourism that creates jobs and promotes local culture and products”.

[the_novelty] => In the context of the high-end restaurant business in India, this study demonstrated that the quality of relationships within the business team (internal social capital, ISC) positively affects the quality of relationships formed with outsiders (external social capital, ESC). This phenomenon was mainly due to the collectivist culture in India, whereby good relationships (cultivated internally and externally) give rise to social support and identity. Despite that, only ISC has a positive impact on the knowledge sharing index (KSI) which, in turn, acted as a driving force for new product development (NPD). The results were obtained by deploying partial least square structural equation modeling to analyze the input data collected from 523 participants from the managerial team of high-end restaurants in India. For future studies, the authors proposed to investigate other determinants of sharing behaviors (e.g., resilience-building capacities, employee engagement, psychological ownership), different types of capital (e.g., financial and human), and other outcomes of knowledge sharing (e.g., customer orientation, creativity performance, and job performance).
[the_background] => Innovation and new product development (NPD) are key elements in defining successful hospitality organizations, such as hotels, tour agencies, restaurants, and food and beverage providers. Meanwhile, both internal and external social capital (SC) were seen as reliable predictors of knowledge-sharing behaviors. Despite the confirmed influence of knowledge-sharing behaviors in facilitating service innovation in tourism firms and restaurants, researchers have yet to determine if SC is a determinant of knowledge-sharing intention (KSI) and new product development (NPD). In order to fill up the research gap, this study investigated the impact of both internal and external SC concurrently on restaurant innovation through KSI and NPD. The results acted as a valuable reference for the government to design policies for growing and supporting the restaurant sector.
[the_sdg_impact] => The hospitality industry has taken a brutal hit since the COVID-19 pandemic started, and countless restaurants and hotels were forced to close down. In the current recovering stage of this industry, innovative plans are crucial to catch up with the new norm that altered the demand and preferences of consumers. By examining the factors affecting innovation, this research strived to facilitate new product development in restaurants. Thus, it realized UNSDG 8: Decent Work & Economic Growth.

[graphic_abstract] =>

[the_novelty] => By applying modern research tools like remote sensing (RS) and geographic information system (GIS), this study showed that eight mid-sized Indian cities underwent a rapid outward expansion of built-up areas, with irregular shapes of built-up patches. Furthermore, secondary urban core and urban fringe showed an increasing trend. Despite the uptrends, there was a decline in population density in most cities. Urban sprawl index (USI) was formulated by combining eleven significant variables related to urban sprawl patterns and typologies from open source datasets. Such index can be used in developing and under developed countries where data availability is a major constraint. The urban sprawl index (USI) varied from 20.73 to 11.28 in Thiruvananthapuram Urban Agglomeration (UA) and Dehradun UA.
[the_background] => Urban sprawl refers to the expansion of poorly planned, low-density, auto-dependent development, creating high segregation between residential and commercial uses. It causes adverse effects on the environment and biodiversity in India. Although urban growth is likely to take place mainly in mid-sized cities, thorough research emphasizing urban sprawl assessment of mid-sized cities remains scarce. Hence, this study adopted several modern research tools to analyze the spatio-temporal urban sprawl in eight mid-sized Indian cities from regions with different physiography. Besides enriching the database of the urban sprawl index (USI) for future research, the output of this research served as a reliable reference for the local authorities to plan for sustainable urban development.
[the_sdg_impact] => Proper urbanization is crucial for the healthy development of the economy, society, and environment of any country. On the other hand, urban sprawl is known to bring the residents and the environment negative consequences, such as water and air pollution, increased traffic fatalities and jams, and loss of agricultural capacity. As the findings of the study serve as a reference to strengthen national and regional development planning, it indirectly contributes to the realization of UN SDG 11: Sustainable Cities & Communities.

[the_novelty] => This study provides an overview of the different applications of the aqueous two-phase system (ATPS) in recovering valuables and contaminants from industrial and domestic waste discharges. As a whole, ATPS is simple, efficient, rapid, flexible, economical, and biocompatible. Moreover, its selectivity, purity, and yield are up to the standards and sometimes even better than conventional waste discharge treatment technology, making it an ideal extraction and purification technology. Additionally, literature also proved that the superior capabilities of ATPS are fruits of continuous research and development of the system, ultimately transforming it into a versatile mechanism suitable across various industries to purify waste discharges. In light of its elaborate benefits, the study suggests that the system be made compatible with the industrial scale to improve the integration and application process, adding value to the respective waste streams.
[the_background] => A well-designed product manufacturing system depends on the efficiency of production and valuable product reclamation, and its downstream waste management strategy. Alas, conventional extraction and purification technologies incur high operational costs, produce lower yield, lack specificity and up-scalability, and use non-eco-friendly components. Alternatively, the aqueous two-phase system (ATPS) has been identified as a better option to overcome the limitations of existing technologies and tools. Therefore, this study aims to review the application of ATPS in diverse industries, emphasizing its capabilities and suggesting ways to improve its industrial-scale implementation.
[the_sdg_impact] => According to GAIA, a global network working towards a just and waste-free world without incineration, approximately 2.01 billion tons of waste are generated annually. Unless effective measures are put to work, it is projected that by 2050, the total amount of waste generation will increase by 70% to 3.4 billion tons. Accordingly, Zero Waste initiatives have been adopted in various regions as a sustainable solution to address such waste crisis. Based on the outcome of this review, the aqueous two-phase system (ATPS) could potentially contribute to achieving the targets of the UN’s 12th Sustainable Development Goal, Responsible consumption and production. The adoption of said system across various industries would lead to environmentally sound management of chemicals and wastes throughout the production life cycle while complying with the agreed international framework of Zero Waste.

[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => This study demonstrates that when dihalobenzoic acids and pyridyl units (both non-mesogenic) are mixed in an equimolar ratio, a hydrogen-bonded (HB) complex with liquid crystalline behavior (mesomorphism) will be formed. Compared to monohalobenzoic acid HB complexes (with the same pyridyl units), higher liquid crystallinity (mesomorphic thermal stabilities) is observed in dihalobenzoic acid HB complexes. When comparing the effect of different dihalobenzoic acids, 4-chloro-2-fluorobenzoic acid HB complexes exhibit higher liquid crystallinity than 2,4-dichlorobenzoic acid HB complexes. In addition, when a series of pyridyl units with increasing chain length are used, the HB complexes exhibit an increasing liquid crystalline thermal range initially but followed by a downtrend. These results are obtained by studying the samples using various characterization techniques, such as infrared spectroscopy, polarizing optical microscopy, and differential scanning calorimetry.
[the_background] => Studies related to liquid crystals (LC) formed through hydrogen bonds have been receiving attention due to their increasing demand in applications like electro-optical and laser devices. The thermal stability of liquid crystals (mesomorphs) relies on various factors, including dipole-dipole interactions, London dispersion forces, dipole-induced dipole interactions, polarity, and polarizability of different molecules. Meanwhile, terminal polar substituents on molecules could significantly change the polarity and polarizability of the system, giving rise to the enhancement or stabilization of mesomorphism. Due to the intriguing phenomena observed in hydrogen-bonded LC systems and the limited number of LC research focusing on mixtures of dihalobenzoic acid and pyridyl units exhibiting, this study aims to examine the effect of hydrogen bond interactions in non-mesomorphic binary systems (using dihalobenzoic acids) on liquid crystalline behavior. These results serve as a valuable complement to the existing knowledge base, specifically in the properties of liquid crystal synthesized using various dihalobenzoic acid and pyridyl units.
[the_sdg_impact] => Liquid crystals are a crucial material in applications such as smartphone cameras, device displays, hyperspectral imaging, semiconductors failure analysis, lasers, and pico-projectors. Therefore, an extensive study focusing on understanding and improving liquid crystal properties is necessary to catch up with the emerging applications. The outcomes of this research have successfully enhanced the research on liquid crystals, fulfilling the targets of UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => In the study, the proposed miniature reconfigurable multiple-input multiple-output (MIMO) antenna was developed using a switchable bandstop filter as a decoupling structure that can be used for wireless communication systems. The MIMO antenna can enhance channel capacity and reliability as well as integrate multiple communication standards. The antenna was developed through four major steps: creating a single antenna, followed by developing two-port antennas. Then, the reconfigurable decoupling network was developed, which finally led to reconfigurable MIMO antenna development. When the antenna was tested at two different modes, respectively, various parameters were observed, and the measured results of the antenna verified the simulation results. The study results indicated that the antenna efficiency was 86.8% and 91.47% in Mode 1 and Mode 2, respectively. The study indicated that larger reconfigurable MIMO antennas could be developed in the future, potentially consisting of more than two antenna elements through the proposed isolation technique.
[the_background] => The MIMO antenna with the proposed bandstop filter reconfiguration can enhance channel capacity and reliability as well as integrate multiple communications standards. This signifies that the bandstop filter reconfiguration proposed in the study succeeds. The goal of the study is to prevent mutual coupling between two closely spaced monopole antenna elements and reconfigure the antenna characteristics. In the study, the MIMO antenna with the proposed bandstop filter reconfiguration showed higher isolation at both operating frequencies than the other antennas reported. The bandstop filter decoupling technique contributed to the improvement in the isolation of the antenna. The study evaluated other antennas and indicated that the antenna proposed in the study has a better dimension than other antennas making it easier to integrate into compact wireless devices.
[the_sdg_impact] => Wireless communication systems are increasingly adopted in our everyday life due to flexibility and mobility. Soon, the 5G or fifth generation of cellular networks, one of the fastest wireless technologies to date, would be available globally. The study is strongly associated with “Goal 9: Industry, Innovation and Infrastructure” of the UN’s Sustainable Development Goals (SDG). In the study, the proposed multiple-input multiple-output (MIMO) antenna is regarded as a breakthrough in wireless communication research due to its ability of greater isolation and deeper resonance while integrating multiple communications standards. The antenna’s ability to enhance channel capacity and reliability is better than other antennas of a similar type.

[the_novelty] => This study developed a novel automated diagnostic system to detect and differentiate different stages of chronic kidney disease (CKD) using ultrasound (US) images of the heart. The proposed computer-aided diagnosis system combined image and feature fusion techniques under a graph embedding framework to characterize heart chamber properties of stage 3 to stage 5 CKD patients. Findings indicated an impressive 100% accuracy in differentiating healthy individuals from CKD patients and a 99.09% accuracy in distinguishing between multiple CKD stages with absolute specificity and sensitivity. Moreover, the utilization of non-invasive heart US imagery as part of a computer-aided diagnosis tool does not only provide a cost-effective approach for CKD staging but also would serve as reliable cardiac health surveillance among CKD patients. Thus, clinicians would be able to monitor the heart conditions of CKD patients effectively and propose early interventions as and when needed.
[the_background] => Although the widely available kidney US technique is a relatively low-cost approach to assessing CKD at all stages, it is also time-consuming. It is largely subjected to attending healthcare professionals’ interpretation. Therefore, it is necessary for an automated diagnostic tool to be utilized to improve the reliability of the assessment. Apart from that, CKD patients are known to face a higher risk of developing severe cardiovascular disease. Studies have shown that those with stage 5 CKD undergoing dialysis are 10 to 20 times more prone to the risk of cardiovascular mortality. Hence, continual cardiac assessment of CKD patients, regardless of the disease stage, is necessary to ensure timely intervention and reduce the severity of complications as well as mortality. As a result of such challenges, this study aims to improve the accuracy and sensitivity of CKD screening through automation.
[the_sdg_impact] => Globally, over 75 million people are affected by CKD, making it one of the leading public health problems. Studies have also shown that the mortality rate from CKD has increased up to 41.5% from 1990 to 2017. By developing an effective algorithm to screen for CKD progress using heart US imagery, this study improves the prevention rate of premature mortality from non-communicable diseases, mainly cardiovascular diseases. Additionally, the system is generalizable to other medical conditions, hence could potentially serve as a reliable diagnostic tool for the global burden of various other diseases.

[video] =>
[the_novelty] => This study discloses that the emission of oxides of nitrogen (NOx) from a biodiesel engine is minimal when running on Pongamia ester (PE) with 10% oleic acid at a compression ratio (CR) of 17.5 and engine load of 81%. Upon optimization, the NOx is reduced by 72% (100 ppm) at a 2% loss of brake thermal efficiency (BTE) (30.42%). A stationary single-cylinder, four-stroke, water-cooled, variable compression ratio (VCR) compression ignition engine is used in this study. Meanwhile, the optimization of operating conditions involves scientific methods such as the design of experiments (DOE), analysis of variance (ANOVA), regression analysis, and multiobjective particle swarm optimization (MOPSO). In order to fine-tune the current study, future research may use a biodiesel engine with higher flexibility in the variability of engine load as the current engine load can only be controlled at the steps of 25%.
[the_background] => Biodiesel is an excellent alternative for conventional combustion-based applications, such as automobiles and power plants. Pongamia oil (PE) (derived from inedible plants) is known as a highly potential source of biodiesel fuel. For better understanding, scientists compared the use of neat PE and PE blends containing diesel fuel. Although PE blends achieved higher brake thermal efficiency (BTE) and combustion duration, there was an increase in NOx emissions. To overcome that, various types of biodiesel additives and their effect have been studied. Despite that, the number of reported studies focusing on the effect of oleic acid additives (e.g., combustion performance, NOx emissions) on biodiesel is still scarce. Furthermore, no optimization study has been carried out to ascertain the optimum oleic acid concentration for the desired reduction in NOx emissions without compromising the combustion performance. Thus, this research strives to investigate the effect of oleic acid additives on the performance and NOx emissions in a PE fuel-operated biodiesel engine. Optimization of the controlling parameters is also conducted to maximize the engine efficiency and minimize NOx emission. The results of this study are valuable for the biotechnology field to provide optimal solutions in improving the efficiency of biofuel while minimizing NOx emissions.
[the_sdg_impact] => In the U.S., the burning of fossil fuels accounted for 74% of greenhouse gas emissions in 2019. This alarming scenario implies the urgent need for renewable energy before the environmental damages worsen. Despite the existence of biodiesel which is adequately efficient and less harmful, this study went the extra mile to optimize the performance and properties of biodiesel. Hence, it fulfills UNSDG 7: Affordable & Clean Energy and UNSDG 13: Climate action by increasing the share of renewable energy in the global energy mix.

[the_novelty] => This study reveals the effect of low-temperature annealing on the properties of tin-doped ZnO [Zn(1-x)Sn(x)O] polycrystalline thin films with a hexagonal wurtzite structure. After being annealed, significant improvement in the electrical parameters is observed. The changes in physical properties include a change in crystal orientation from (002) to (100), an increase in the crystallite sizes (when annealed at 100 °C), an enlargement of optical bandgap from 3.17 to 3.44 eV, an increase in donor-related defects such as oxygen vacancies and Zn interstitials, and an improved blue light emission. Meanwhile, the doping process brings about an increase in oxygen-related defects, a two-order decrement in the resistivity as well as a three-order increment in the carrier concentration. The thin films were grown on glass substrates using DC magnetron reactive co-sputtering techniques. The characterization techniques involved are such as X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), photoluminescence (PL) analysis, X-ray photoelectron spectroscopy (XPS), and van der Pauw resistivity measurement.
[the_background] => Zinc oxide (ZnO) is a reputable Transparent Oxide Semiconductors (TOS) for electronic and photonic applications. Its conductivity can be improved tremendously using tin (Sn) dopant, which does not cause any serious lattice distortion. Past studies show that optimized annealing could enhance the overall physical properties of Sn-doped ZnO thin film. Nevertheless, to date, the number of studies focusing on low-temperature annealed Sn-doped ZnO thin film fabricated by DC magnetron reactive co-sputtering remains scanty. Therefore, this study aims to investigate the physical properties of Sn-doped ZnO thin film prepared using the said technique and examine the effect of low-temperature air-annealing. The output of this research expands the knowledge base specifically in the potential application of Sn-doped ZnO thin film as optoelectronic devices (e.g., UV photosensors and thin-film transistors).
[the_sdg_impact] => The rapid advancement of technology has led to the designs of high-technology nano-electronic devices to cater to various industrial needs and end-consumer markets. Such phenomena have created a high demand for materials with superior properties. By introducing an effective way to prepare optoelectronic materials with enhanced properties, the outcome of this study is in line with innovative prospects envisioned by UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => This study investigated the abundance, size and type of magnetic minerals present in a 79-cm long sediment core from a land-locked lake (L-49) in Schirmacher Oasis (SO, East Antarctica). The sediment core spans the past 43,000-years. Apart from the abundance of iron oxide minerals traced through the magnetic susceptibility data, biological processes and wind activity were also found to be significant in contributing sediments to the lake across different timescales in the region. Notably, the findings showed that the SO lakes responded well to the changing climate throughout the last glacial period and the Holocene (11700 years BP to the Present). Such reconstruction of the L-49 sediments’ glacial-interglacial climatic and environmental changes would contribute to the expansion of literature and be useful when developing regional and global climate models.
[the_background] => Since the East Antarctic Ice Sheet (EAIS) is the largest ice sheet in Antarctica, understanding its response to the changing climate is crucial to prevent or be prepared for potential climate-change-triggered environmental catastrophe. However, there is a grave shortage of data on the past behavior of the EAIS throughout the changing timescales and climate. As linkers of continental ice cores and marine sediments, the study of coastal lake sediments would shed some light on ice sheet dynamics, sea-level changes, isostasy, deglaciation, and ice sheet decay. Therefore, this study uses the properties of magnetic minerals to reconstruct glacial-interglacial climatic and environmental changes from sediments of a land-locked lake.
[the_sdg_impact] => According to the data presented by Climate.gov, the global sea level has risen to a new record high in 2020, 91.3 mm (3.6 inches) above 1993 levels. Consequently, more high-tide flooding and other environmental catastrophe are to be expected, leaving behind massive damage to the infrastructure and disrupting the livelihood of many. By providing up-to-date and comprehensive data on the glacial conditions of the largest ice sheet and its role in the rising sea levels, the findings of this study allow scientists, environmentalists, and world leaders to devise urgent and strategic action to combat climate change and minimize its damages.

[the_novelty] => Using an optical vortex beam, this study proposed a novel method for optically immobilizing the red blood cells (RBCs) in a favorable orientation, improving Raman analysis sensitivity in cell membrane studies for higher cell volume. An extensive spectral analysis using the optical vortex beam was compared with the conventional Gaussian beam-based measurements to validate both efficiency and sensitivity of the method proposed. As a result, the optical trapping of RBC in a face-on orientation enabled physiological and biochemical properties of hemoglobin (Hb) molecules near RBC membrane as well as inside the bulk of the cell to be distinguished precisely. Such evidence is crucial to unravel the elaborate potentials of Raman spectroscopy in cellular studies and disease development.
[the_background] => Understanding the role of cell membranes in cellular homeostasis is vital to prevent the development of several non-communicable diseases. The conventional optical immobilization of single functional cell using Gaussian beam limits Raman spectroscopy's potential in efficiently analyzing cell membrane. Such is primarily due to the restrictions in cell orientation with regards to the beam direction and cell volume. Therefore, the study aims to provide a feasible replacement of the beam used in Raman spectroscopy to improve cell membrane analysis and understanding.
[the_sdg_impact] => Over the years, the usefulness of Raman spectroscopy as a non-invasive diagnostic tool for a range of diseases has been well established, not without its limitations. The new method proposed in this study, which utilizes an optical vortex beam instead of a Gaussian beam, enhances the performance of Raman spectroscopy in terms of cell membrane analysis. Based on the outcomes, it is apparent that such innovation could broadly impact the future development of medicines for communicable and non-communicable diseases as envisioned in the 3rd United Nations' Sustainable Development Goal, Good health and well-being.

[the_novelty] => To better understand investors’ buying decisions in life insurance, this study discloses how the investor-agent relationship affects the decision-making process. Trust is among the most influential prerequisites as it fully mediates the effect of agent disclosure and personal rapport on decision-making. Besides that, interaction intensity with agents, co-operative intentions of agents, and sharing of overt and covert information also significantly impact the decision-making process. These insights are derived from a questionnaire answered by 813 policyholders of life insurance companies operating in South India. A partial least square method of structural equation modeling is applied to analyze the data. Future research can expand the study scope of relational selling by focusing on adaptive and team selling behavior and diving into health insurance, auto insurance, and property insurance.
[the_background] => The chances of closing deals in the insurance industry depend mainly on the potential investors’ confidence and trust in the insurance agents responsible for providing valuable and accurate policy information. Although the ethical conduct of agents is known to be a primary determining factor, the effect of investor‒agent relationships on the decision-making process of acquiring insurance policy remains unclear. Hence, this study investigates the impact of relational selling behavior on insurance decision-making and explores the significance of trust in making such decisions. The outcome would provide valuable inputs to insurance companies by highlighting the key relational prerequisites to be emphasized while establishing and maintaining a fruitful long-term relationship with investors.
[the_sdg_impact] => The development of the insurance sector is crucial to the general economic growth of the nation by generating long-term financial resources and employment. Thus, the profitability of the insurance sector ought to be a main national financial agenda. This study has successfully identified the effect of relational selling on life insurance decision-making in India. As the ultimate focus is directed toward promoting sustainable economic growth, the study is well-aligned with UNSDG 8: Decent Work & Economic Growth.

[the_novelty] => Upon assessing the technical efficiency of traditional and corporate agents in the Indian life insurance industry, this study concludes that there is no significant difference between the efficiency scores of traditional and corporate agents. These findings also indicate that efficiency scores and market share are not necessarily negatively correlated, opposing the Quiet life hypothesis. The research is conducted by examining the sales efficiency of 12 traditional and corporate agency channels between 2012 and 2016 using the non-parametric approach of data envelopment analysis (DEA). By minimizing the non-availability of data and increasing the sample size, a more accurate and comprehensive outcome can be expected in future studies.
[the_background] => The profitability of the life insurance industry in India relies strongly on the efficiency of the distribution channels, such as traditional and corporate agencies. However, these agencies are bound to face difficulties like high turnover rate, increasing expenses, and unsatisfying sales figures. Thus, to confront these issues, this study is carried out to focus on the efficiency of insurance distribution channels. Based on the proven low efficiency of both the traditional and corporate media, this study suggests that insurance companies should reduce the number of agents and commission expenses. The output of this research serves as a solid reference for future strategizing and efficiency improvement of distribution channels, including leveraging digital insurance as an alternative distribution channel.
[the_sdg_impact] => The insurance industry is essential for the stability of financial systems because they are part of the prominent investors in financial markets and because the insurers safeguard the financial stability of households and firms by insuring their risks. Therefore, the sustainability and profitability of the insurance industry are critical to the economic growth of a country. By attempting to strengthen the capacity and improve the efficiency of the insurance industry, this study aligns with the targets of UNSDG 8: Decent Work & Economic Growth.

[the_novelty] => By learning form natural enzymes, artificial enzymes (i.e. nanozymes) synthesized using nanomaterials have high potential in achieving or even surpassing the catalytic effectiveness of natural enzymes. Based on the role of amino acids in the active sites of natural enzymes, a desirable catalytic microenvironment can be prepared for nanozymes via simulations. Besides, nanozymes could possess adjustable enzyme-like activities by having coordination structures which are developed according to natural enzymes’ chemical coordination principles. To realize a more ideal nanozyme, future studies could focus on improving the specificity of catalysis as well as the flexibility and variability of active sites.
[the_background] => Nanozymes are artificial enzymes prepared using nanomaterials. They exhibit outstanding properties such as high stability, adjustable catalytic activities, wide range of functionality, high recyclability, and highly feasible for large-scale production. Although there has been significant progress, further optimizations are necessary so as to put nanozymes into applications. With the hope to inspire and to gain more attention from researchers, this study discusses the omnidirectional simulation of natural enzymes from an amino acid microenvironment to metal-free architecture, and to a metal coordination structure. The research output boosts the materialization of highly effective and highly efficient nanozymes which will bring biomedicine and industrial catalysis to a whole new level.
[the_sdg_impact] => Despite the rapid advances of medical science, an effective cure is still in need to treat inherited metabolic disorders which result in a number of life-changing or life-threatening conditions. The achievement of this study paves a clear path and direction as well as creates a realistic hope for the future development of nanozymes research (UNSDG 9: Industry, Innovation & Infrastructure). By being proactive in optimizing the development of nanozymes, patients of inherited metabolic disorders would stand higher chance to recover and live like any other individuals (UNSDG 3: Good Health & Well-Being).

[the_novelty] => With the aim to realize state-of-the-art organic semiconductor (OSCs) via dip-coating, this study has comprehensively discussed the assembly strategy, underlying mechanism, critical factors, and applications of microstructured ultrathin organic semiconductor films (MUOSFs). The critical factors are such as pulling speed, molecular structures, and solution properties. The fundamental rule in preparing MUOSFs with different kinds of molecules (for different purposes) is to focus on the nucleation rate, assembly rate, and recession rate. Such rule will bring balance between the critical factors and, in turn, leads to fabrication of one-dimensional microstripes and two-dimensional films. By applying in-depth knowledge of dip-coating, this study has successfully prepared uniform, continuous, highly ordered, and large-area MUOSFs with monolayer precision. The expansion plan of this research includes dip-coating MUOSFs with face-on molecular orientations, growing continuous 2D molecular crystals over a large area, producing multiple component systems (e.g. cocrystals and heterojunctions), optimizing the overall morphology, and fabricating MUOSFs on wafers.
[the_background] => The potential of organic electronics is proven by the successful commercialization of active-matrix organic light-emitting diodes (OLEDs) for high-end smartphone displays. This milestone has gained OSCs tremendous attention which gave rise to the ambition of further enhancing the properties and performance of OSCs. As ultrathin OSC microstructures comprise one to several molecular layers (i.e. microstructured ultrathin organic semiconductor films (MUOSFs)), a highly controlled assembly method is in high demand to improve and design the OSCs’ properties for different applications. Aiming at the molecular-level precision of dip-coating technique, this study emphasizes on the assembly strategy, the underlying mechanism, and potential applications of MUOSFs. The output of this study plays a significant role in facilitating future research on optimizing the properties and performance MUOSFs.
[the_sdg_impact] => OSCs have promising prospects for use in various electrical and optoelectric devices such as solar cells, transistors, photodetectors, and lasers. With the advantages of being eco-friendly, lower-cost and flexible, the advances of OSCs will be a game-changer for the development of electronic devices. This study supports and enhances the research related to OSCs and, hence, it fulfils UNSDG 9: Industry, Innovation, and Infrastructure.

[the_novelty] => This study has revealed the crucial structural engineering to effectively develop Eu2+-doped silicates phosphors for LED applications. The distinctive luminescence properties of Eu2+ are attributed to the centroid shift of the 5d levels subshell, the energy difference between the lowest and highest 5d levels (crystal field splitting), the energy difference between the maximum of the lowest excitation band and that of the emission band (stoke shift), as well as the broad emission bandwidth. Therefore, the Eu2+ emission in silicates can possibly be tuned via various structural strategies, such as substitutions (to modify the chemical composition and crystal structure), identifying an optimal crystallographic site for Eu2+, and controlling crystalline phase transition. The results are diverse when different crystal structures and/or local structures are involved. The progress of recent research focusing on daily applications has been outlined comprehensively. These applications include white LED lighting, liquid-crystal displays (LCD) LED backlights, and near-infrared LEDs for medical and night-vision use. In order to keep advancing of Eu2+-doped silicates phosphors for emerging LED applications, future studies can focus on the deeper understanding on the relationship of structural rigidity and Eu2+ luminescence, as well as the discovery of new phosphor sytems.
[the_background] => Although phosphor-converted light-emitting diodes (pc-LEDs) have been commonly used, there is still room for improvement for its performance which mainly relies on the luminescence properties of phosphors used. Meanwhile, besides being low cost, Eu2+-doped earth abundant silicates phosphors are excellent luminescent materials for optoelectronic applications. With tunable bandwidth, their emission colors can cover near-ultraviolet (n-UV) to near-infrared (NIR). Due to its high potential, scientists are aspired to push the limits of Eu2+-doped silicate phosphors in materializing the state-of-the-art LED applications. This study contributes by shedding light on the significant structure−property relationships and the Eu2+ photoluminescence mechanism. Such effort would facilitate researchers in developing higher-performance Eu2+-doped phosphors to cater emerging applications.
[the_sdg_impact] => The global LED lighting market reached a value of US$ 84 Billion in 2020. The high global market demand indicates the importance of LED for diverse applications (both industrial- and consumer-use). By focusing on pushing the limits of LED using Eu2+-doped silicates phosphors, this study shows good alignment with UNSDG9: Industry, Innovation & Infrastructure. Cutting-edge LEDs will directly enhance the features and performance of countless devices and equipment.

[the_novelty] => This study highlights the adverse effects of opportunistic lung cancer screening promotion from the non-smoking Taiwanese women population perspective. Findings indicate that the rise of low dose computed tomography (LDCT) screening among low-risk women population led to 6 times higher early-stage lung cancer detection from 2004 to 2018 with no change in the incidence of late-stage lung cancer. Even with a consistent lung cancer mortality, the 5-year survival rate has more than doubled within the given period. This concludes the potential misleading feedback that follows unnecessary excessive cancer screening. Without dismissing the benefits of LDCT screening for lung cancer, the study suggests the target groups be heavy-smoker specific for better reliability instead of broad low-risk population screening.
[the_background] => Over the years, lung cancer screening criteria have expanded, and opportunistic screening for the disease has been actively promoted among lower-risk groups. Increased incidence of lung cancer has been reported even as the smoking population and other risk factors continue to decrease. Considering these observations, researchers find that it is crucial to understand the association of lung cancer incidence with the promotion of screening in a predominantly non-smoking population. Potentially, the findings would highlight the health and economic impacts as well as reliability of opportunistic screening among lower-risk groups, serving as an important reference for healthcare policymakers.
[the_sdg_impact] => According to WHO, in 2020 alone, out of 2.21 million lung cancer cases reported, there were approximately 1.80 million deaths. Apart from prevention efforts, early detection is believed to play a prominent role in reducing cancer mortality. Consequently, opportunistic screening has been heavily promoted, not just among heavy smokers, but also among those from the lower-risk population. However, this study’s findings elaborated on the adverse effects of such excessive screening and the economic impact on national insurance coverage as a result of overdiagnosis and downstream medical procedure expenses. Accordingly, healthcare policymakers could refer to these findings for a better decision-making process concerning health coverage, and quality and affordability of medical services.

[the_novelty] => This study has successfully developed a high-efficiency neutron detector array with an exceptionally low background to measure the cross-section of the 13C(α,n)16O reaction at the China Jinping Underground Laboratory (CJPL). Comprising 24 3He proportional counters embedded in a polyethylene moderator, and shielded with 7% borated polyethylene layer, the neutron background at CJPL was as low as 4.5 counts/h, whereby 1.94 counts/h was attributed to the internal α radioactivity. Remarkably, the angular distribution of the 13C(α,n)16O reaction was proven to be a primary variable affecting the detection efficiency. The detection efficiency of the array for neutrons in the range of 0.1MeV to 4.5 MeV was determined using the 51V(p, n)51Cr reaction carried out with the 3 MV tandem accelerator at Sichuan University and Monte Carlo simulations. Future studies can be planned to focus on further improvement of the efficiency accuracy by measuring the angular distribution of 13C(α,n)16O reaction.
[the_background] => Gamow window is the range of energies which defines the optimal energy for reactions at a given temperature in stars. The nuclear cross-section of a nucleus is used to describe the probability that a nuclear reaction will occur. The 13C(α,n)16O reaction is the main neutron source for the slow neutron capture process (s-process) in asymptotic giant branch (AGB) stars, in which the 13C(α,n)16O reaction occurs at the Gamow window spanning from 150 to 230 keV. Hence, it is necessary to precisely measure the cross-section of 13C(α,n)16O reaction in this energy range. A low-background and high detection efficiency neutron detector is the essential equipment to carry out such measurements. This study developed a low-background neutron detector array that exhibited high detection efficiency to address the demands. With such development, advanced studies, including direct cross-section measurements of the key neutron source reactions in stars, can be conducted in the near future.
[the_sdg_impact] => Low-background neutron detectors play a crucial role in facilitating research related to nuclear astrophysics, neutrino physics, and dark matter. By improving the efficiency and upgrading the technological capability of low background neutron detectors, this study indirectly contributes to the enhancement of scientific research. Additionally, fields involving material science and nuclear reactor technology would also benefit from the perfection of neutron detector technology. Taking into consideration the potential application and expansion of these findings, such innovative attempt aligns well with UNSDG9: Industry, Innovation & Infrastructure.

[the_novelty] => This study showed the significance of hadronic interactions in developing collective flow in the high-baryon-density region. The statement was derived from the finding whereby a mean-field mode with strong repulsive interaction is needed to reproduce the recent STAR results of 10–40% centrality at √sNN = 3 GeV. Besides that, the energy dependence of directed and elliptic flows was discussed comprehensively. The research was conducted based on Monte Carlo event samples of Au+Au collisions at center of mass energies of √ sNN = 2.11 – 4.9 GeV generated by version 3.4 of the UrQMD model (including both cascade and mean-field modes). These findings contribute to a richer knowledge base in particle physics.
[the_background] => High-energy (relativistic) heavy-ion collisions produce an enormous amount of subatomic particles in all directions. In such collisions, the term “flow” describes how energy, momentum, and number of these particles vary with direction. Collective flow describes a movement of a large number of subatomic particles either in a common direction or at a common magnitude of velocities. Meanwhile, elliptic flow measures how the flow is not uniform in all directions when viewed along the beamline. Besides proving the existence of quark-gluon plasma, elliptic flow is one of the most important observations measured at the Relativistic Heavy Ion Collider (RHIC). A recent study conducted by Solenoidal Tracker at RHIC (STAR) implied that the hadronic interactions dominated the equation of state in collisions at center of mass energies of √ sNN = 3 GeV (a region with a high baryon density baryon chemical potential of 750 MeV). As an effort to explore phase structure in the high baryon density region, this research deployed a hadronic transport model, known as the ultra-relativistic quantum molecular dynamics model (UrQMD), to study the directed and elliptic flows in the high baryon density region by using Monte Carlo event samples of Au+Au collisions. Other than marking a new milestone for the second phase of the beam energy scan at the RHIC (BES-II) program, the outcome paves the path to understanding experimental data from upcoming experimental facilities focused on the high baryon density region.
[the_sdg_impact] => A better understanding of the properties of the high baryon density region is essential in facilitating future research related to particle physics. This is crucial as the advancement of particle physics will directly impact the expansion of nuclear physics and other closely connected fields. In extension, such enhancement of advanced physics research contributes to the realization of 9th UNSDG: Industry, Innovation & Infrastructure.

[the_novelty] => The novelty of this research is observed in its contribution in enhancing the energy (biogas) production in the standard waste treatment of POME, highly polluted wastewater, through the ultrasonication pre-treatment. The standard waste treatment of POME involves the anaerobic digestion process that produces energy (biogas) as its main outcome. By incorporating the proposed pre-treatment method, the researchers found that POME particle size reduced while its organic surface matter increased for microbial degradation. Additionally, the metabolic activity of anaerobes involved in the digestion process is also reported to increase. These findings conclude that the ultrasonication pre-treatment is promisingly effective as it enhances anaerobic digestion and increases biogas production rates at 30 oC to 35oC. Therefore, this research not only enhances energy production from waste materials but also improves the standard waste treatment method, facilitating multiple stakeholders in strategizing the promotion and practice of generating energy from waste more effectively in the future.
[the_background] => To reduce dependence on fossil fuels, renewable energy sources are effective alternatives in overcoming this issue. While there are various forms of renewable energy, an upcoming clean and promising renewable energy is biogas obtained from the anaerobic digestion process. This same process is used to treat POME, making POME a high potential renewable energy source in Malaysia since it is one of the country’s primary commodities. The standard treatment of POME is also lower when compared to other alternatives, prompting a large amount of work focusing on the use of POME as a cheap source for biogas production. However, limited attention has been paid to enhancing the biogas production process itself, motivating the researchers to fill this gap by investigating the use of ultrasound as pre-treatment and identifying the optimum temperature range – an important parameter in the digestion process.
[the_sdg_impact] => The economy of a region is largely dependent on its energy reservoir, where fossil fuels remain the main source of energy. However, Shell International predicts that by 2050, 30% of global primary energy consumption will consist of renewable energy. Thus, the use of renewable energy is a future imperative, requiring relevant parties to ensure the production efficiency of these resources. In improving the conversion process of waste to energy, this research proposes a valuable, sustainable strategy, closely aligning with UNSDG 7: Affordable and Clean Energy. Centering on POME, a source of modern energy, this research further enables clean and efficient energy usage.

[the_novelty] => When it comes to solar power, the conventional generating system has evolved to include an increasingly popular alternative, the concentrator photovoltaic (CPV) system, as it is highly efficient in converting power (46%). CPV systems require an appropriate layout design that involves massive land utilization, thereby increasing the cost to function optimally. These consequences must be reduced if solar energy is to be implemented and adopted worldwide. Therefore, this study attempt to mitigate these consequences by developing a computational algorithm in the MATLAB platform capable of precisely estimating and optimizing the levelized cost of electricity (LCOE) of a CPV field layout using local meteorological data. As a result, the proposed computational method can facilitate various stakeholders such as researchers and engineers to reduce the cost of implementing optimal layout design for CPV, simultaneously increasing the efficiency of generating solar power. Unlike previous works, this study also accounts for various factors that can potentially influence energy generation and cost (e.g., land cost, local meteorological data, geographical location, the land aspect ratio of CPV farms, etc.)
[the_background] => Effective space allocations in solar farms are crucial since inappropriate space design of concentrator photovoltaic (CPV) systems can cause optical losses due to the shadowing between adjacent CPV systems. Thus, capable of leading to the deterioration of the overall electrical generation of solar power plants (SPP). Such an issue can be overcome by increasing the separation distance between the adjacent CPV systems, implying a possible increase in land-related costs due to ineffective land use. Therefore, this study focused on optimizing the layout design optimization in the SPP to attain the best trade-off between land usage and energy generation using a computational algorithm.
[the_sdg_impact] => According to the US government agency, Office of Energy Efficiency and Renewable Energy, the US solar power capacity has grown to an estimated 97.2 gigawatts (GW). The International Energy Agency also projects solar energy to provide 4% of the total global electricity demand by 2023. Hence, the growing popularity of solar energy calls to attention the need for effectively designed SPP layouts to cater to this demand. This research simultaneously demonstrates its impact on UNSDG 7: Affordable and Clean Energy in contributing to this solution. It enables the accessibility and affordability of solar power by reducing costs incurred during solar power installations. Furthermore, this research potentially improves solar power generation, thereby increasing the use of renewable energy and improving global energy efficiency.

[the_novelty] => This study proposed a new regularization technique known as batch contrastive regularization to address the overfitting issues in deep neural networks. When the system additionally learns to compare the similarity between similar images and dissimilarity between two unrelated images, it performs better on unseen samples, not only on training samples. The three contrastive losses involved in improving the generalization performance were centroid contrastive loss, sample contrastive loss, and multicenter loss. The two-headed network could speed up multi-task learning by having one head for classification and the other for regularization. Evaluation using the CIFAR-10 and CIFAR-100 datasets showed over 11% improvement for ResNet50 on CIFAR-100.
[the_background] => Overfitting happens whereby a system performs very well on the training set but poorly when deployed. Deeper neural networks have more parameters and would be overfitting, especially when training samples are insufficient. Previously, regularization techniques failed to enrich the model because the cross-sample information was not considered. Meanwhile, although contrastive-based regularization is promising, several limitations were identified. For the first time, an in-depth study was conducted to understand batch loss regularization for general classification tasks.
[the_sdg_impact] => Deep learning is a disruptive technology that revolutionizes many industries. It is estimated to improve 82% of the outcome metric of SDG, including manufacturing (SDG9), climate action (SDG13), and sustainable city (SDG11). There is a need to improve the way deep learning models are trained to build more effective DL systems.

[figures] =>
[video] =>
[the_novelty] => This research reported the beneficial effect of creativity on subjective well-being in two studies. The first study showed that undergraduate students and working adults with higher creativity had self-reported a higher level of well-being. Then, a subsequent study was conducted to further study the causal relationship between creativity and well-being. The second study indicated that participants who recalled their past creative achievement showed a higher level of well-being. Based on the proven bidirectional relationship between creativity and well-being, future research should consider the significance of a reciprocal relationship between two constructs.
[the_background] => Although well-being is known to promote creativity, there are insufficient in-depth studies on the effect of creativity on well-being. Meanwhile, subjective well-being focuses on both positive and negative aspects of life as well as satisfaction with life. It is different from proxies, like happiness, psychological/emotional well-being, which focuses on the positive dimension. Also, creativity is being perceived differently due to cultural differences, especially between the East and West. This study examined the positive effect of creativity on subjective well-being in the Malaysian context to address those differences.
[the_sdg_impact] => Subjective well-being is useful in appraising the well-being of populations. Meanwhile, there has been increasing acknowledgment of mental health's important role in achieving global development goals. In order to fulfill UNSDG 3 (Good health and well-being)'s vision of improving physical and psychological wellness, this study demonstrates that creativity is a promising factor to enhance well-being among young adults and working adults.

[video] =>
[the_novelty] => This study developed an approach to automatically track and distinguish various operation statuses of legacy manufacturing machines by analyzing the vibration data collected from a retrofitted wireless vibration sensor. To test its feasibility, the parameter-free Internet-of-Things (IoT) approach was deployed on a 3-speed industrial exhaust fan in a limestone processing factory. The operation status was successfully tracked with average accuracy and standard uncertainty of 98.6% and 1.06%, respectively. This promising approach could be applied to other factories, such as palm oil refineries and concrete plants.
[the_background] => While riding the wave of Industrial Revolution (IR) 4.0, data plays a crucial role in decision-making in every business sector. However, many small and medium enterprises (SME) factories still use manufacturing machines without any computing function, let alone internet connectivity. This implies that access to operational data is limited and painstaking. To help these SMEs catch up with the IR 4.0, this study designed an end-to-end wireless IoT and parameter-free approach to capture and analyze vibration data, which outputs critical operational status. By having these data, stakeholders of the business will have a clear understanding of their machines' productivity to make better business decisions.
[the_sdg_impact] => In manufacturing, big data can include data collected at every production stage, including data from machines, devices, and operators. The data serves as a reliable guide for business planning and strategy with proper analysis and interpretation. Besides getting prepared for IR 4.0, the sensor retrofitting solution developed by this study also helps SMEs attain better operation visibility (UNSDG 9: Industry, Innovation & Infrastructure).

[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => This study determined the factors that play vital roles in the consumers' decision-making to transition from cash to m-payment. This was done via a uniquely developed conceptual model that incorporated the push-pull-mooring (PPM) framework with the perspective of status quo bias (SQB). The studied parameters were monetary value, alternative attractiveness, trust, perceived security and privacy, switching costs, traditional payment habit, and inertia. Results suggest all but two of the developed hypotheses were statically supported. This could be because most respondents do not use mobile payments daily. Thus, the cumulative financial savings would be difficult to be noticed by mobile payment users in such a situation. In conclusion, with the increase in mobile payment adoption and decrease in cash usage, cash costs can be decreased. These costs include the printing, storing, and distributing cash spent by the banks and government. These savings can provide the government with excess funds, which can be diverted to develop other sectors of the country's economy.
[the_background] => The Malaysian government has consistently promoted mobile payment adoption due to its numerous benefits and advantages, including enhancing customers' checkout experience. However, consumers in Malaysia still find it more comfortable using cash to make payments for goods and services despite initiatives to shift Malaysia into a cashless society. Apparently, cash is still king among the payment methods available despite the urge from authorities. Hence, this study looks into the factors influencing switching intention from cash to mobile payment.
[the_sdg_impact] => In Malaysia, there is a solid foundation for m-payment to thrive as the number of mobile connections in terms of the total population is at 125% (We Are Social, 2019). In fact, the Central Bank of Malaysia has been trying to accelerate the promotion of m-payment adoption as it recognizes the numerous benefits of m-payment (Bank Negara Malaysia, 2018). However, consumers have a certain level of hesitancy concerning these initiatives. Therefore, the outcome of this study contributes to SDG9: Industry, Innovation, and Infrastructure as it explores means to understand consumer behavior and willingness to adapt to the shifting payment method initiatives.

[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => This study introduced a new path-finding strategy, known as Energy-efficiency Path-finding Strategy (EPS) in the Air-Ground Collaborative Wireless Sensor Network (AGCWSN), which could potentially enhance the efficiency of data collection for drones. Two phases were involved in this study, i.e., intermediate point selection phase and path selection phase. The intermediate points among the group sensor nodes allowed the drone to collect data rapidly (reduced flight distance). Generic Algorithm (GA) shortened the flight path generation time in the path selection phase. It archived the pre-set condition (e.g., maximized data collection and returned to the base station before its power was drained out). Compared to other existing data collection strategies, EPS achieved lower data delivery delay and better utilization of the mobile sink’s battery capacity, as simulations showed. These two major advantages could compensate for its higher packet loss percentage. By implementing this improvement, data collection efficiency in flight path generation and energy consumption for drones can be significantly enhanced.
[the_background] => Drones are being deployed into different industries to improve productivity and efficiency. For example, Amazon deploys drones in their delivery system to shorten the last-mile delivery process, while drones in sustainable agriculture can reduce the data collection delays. However, one of the main drawbacks is the limited battery capacity of the drone during its flight. In this study, the data collection process of a drone in agriculture will be further improved by optimizing the energy usage of the drones and by shortening the flight trajectory taken by the drones. Despite having several reported approaches which shortened the delays, the flight trajectory taken by the mobile sink has not been addressed yet. Thus, this study proposed a new path-finding strategy to overcome that.
[the_sdg_impact] => As industrialization advances rapidly, drones play essential roles in maximizing productivity. Their potential has been proven especially in goods delivery and sustainable agricultural activities. The solutions proposed by this research can boost the productivity and operating duration of drones. Therefore, it contributes to the materialization of UNSDG 9’s target, i.e., build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation.

This study adopted fully modified ordinary least squares, canonical cointegrating regression, and dynamic ordinary least squares in performing long-run estimations to test the EKC hypothesis on the role of corruption on transport CO2 emission from 1990 to 2017 in the country. The retrospective study showed that transport CO2 emission increases directly proportionally to corruption, demonstrating environmental degradation that corruption causes. The research also identified that the EKC hypothesis does not apply in Malaysia, suggesting that the country has yet to attain the level of economic growth required to reduce greenhouse gas (GHG) emissions. The outcome of this study will be a significant tool for developing effective government policies to reduce transport CO2 emission with proper governance of the sector.
[the_background] => The transport sector is one of the major contributors to global CO2 emission, accounting for 24% of the total. In Malaysia, road transport contributes to 85.2% of the total transport emission. The local transport industry is largely intertwined with the government predisposing it to undesirable corruption practices, contributing to harmful environmental policies and misallocation of environmental resources. The outcome of this study showed such practices provide the precarious impact on the environment. If corruption is left uncontrolled, it will lead to a more harmful outcome in the long run. The study also made aware that Malaysia is far from attaining economic growth that can support CO2 emission mitigation due to the lack of advanced technology and widespread corruption in the transport sector. Hence, sustainable long-term efforts are needed to mitigate CO2 emissions from the transport industry. The efforts will include introducing stringent anti-corruption policies and laws, enhancing research and development in the transportation sector, and implementing the latest environmental-friendly technologies to reduce GHG emissions. This study is the first in the country to explore the impacts of transport EKC locally with corruption as an impacting factor, which has proven the importance of better governance on this matter.
[the_sdg_impact] => This study resonates very well with the United Nation's Sustainable Development Goal (UNSDG) 13: Climate Action. The specific target involved under the UNSDG is Target 13.2: Integrate climate change measures into national policies, strategies, and planning. Despite the study being conducted locally, the intention is applicable globally, given that climate change is an issue that is getting more attention on the global pedestal by day. The atmospheric concentrations of the major GHG continue to increase worldwide. To limit global warming to 1.5°C above pre-industrial levels following Paris Agreement, the world would need to attain net-zero carbon dioxide emissions by 2050. Locally, Malaysia's intention to cut GHG emissions by 45% by 2030 can only be achieved if the government develops a sustainable transport policy that optimally controls the traffic rate, enhances environmental performances, and creates public awareness on the impact of transport emission on the environment. Hence, this study is a wake-up call to the authorized agencies and public to do the needful to cut down GHG emissions in general to save the planet that has been home and provided us with everything.

[the_novelty] => Using one of the most established technology adoption theories, UTAUT (Unified Theory of Acceptance and Use of Technology), this research examines the behavioral intention of potential consumers' in adopting solar power technology. From a social influence perspective, the researchers discovered that cost perception has a more significant positive effect than knowledge. Social influence is also revealed to have a more substantial effect on consumers' behavioral intention than other conditions supporting innovation. However, these conditions positively mediate the relationship between social influence and behavioral intention. This research provides valuable insights into consumers' perspectives on renewable solar energy, which is limited since previous studies do not specifically address the solar energy context. These insights guide multiple stakeholders such as the Malaysian government and relevant commercial suppliers on successfully promoting the use of solar energy. Some strategies highlighted by the researchers include providing financial support and sufficient information to potential consumers as well as creating favorable impressions of technology use. Additionally, this research also prompts the need for effective policies that cater to the needs of large corporations and small households, encouraging the use of renewable technology in Malaysia by allowing stakeholders at every level to contribute to the nation's sustainability plan.
[the_background] => The increase in global population and economic development has also contributed to the significant boom in electrical consumption worldwide. While non-renewable energy sources are still expected to constitute 77% of the energy consumption in 2040, renewable energy has been gaining fast traction recently, with solar power being one of the most popular sources. However, the adoption rate for solar photovoltaic technology among households remains low, prompting the researchers to focus on the reasons that influence Malaysian consumers' intention to adopt solar energy. The research accounts for the consumers' perspective and examines the influence of the price and knowledge dimensions on consumers' intention to use solar energy.
[the_sdg_impact] => Globally, fossil fuels (e.g., coal and oil) account for 70% of the increasing demand for energy (International Energy Agency, 2017), while in Malaysia, fossil fuels generate 90.6% of the nation's total electricity. This situation calls for the successful implementation of solar energy as an alternative energy source since it is considered one of the most viable forms of renewable energy. In terms of global sustainability, this research contributes to the achievement of UNSDG 7: Affordable and Clean Energy. By focusing on consumers' views on cost and information sharing on solar power, this research provides stakeholders with insights for future strategies to promote access to solar power's affordable and reliable use. These insights can also reduce the dependency on fossil fuels to ensure energy efficiency and a balanced global energy mix. Additionally, the impact of this research is also observed in relation to UNSDG13: Climate Action, where it improves the overall awareness of climate change mitigation.

[the_novelty] => Unlike previous phase change material (PCM), which could only store heat, this study fabricated a PCM capable of solar energy conversion and heat storage. The visible light-harvesting PCM could absorb an enormous amount of heat and store the heat in the form of latent heat. As a result, only a smaller tank is required and eliminates solar collectors' usage. The fabrication involved dip-coating myristic acid (MA) tablets into layers of polymer coating solution with reduced graphene oxide (RGO). The highest heat storage, solar energy conversion, and storage efficiency (21%) were achieved by the light absorptive polymeric form-stable composite phase change tablet (RGO-PARB/MA) when loaded with 1.5 wt% RGO. The 1.5 wt% RGO-PARB/MA recorded up to 1,000 thermal cycles with less than 2% change in thermal properties. The new PCM can be further optimized to enhance the efficiency of existing solar heating systems.
[the_background] => The current solar water heater system uses sensible heat storage that involves a large mass of water. Since most roofs are not meant to support such load, the storage has to be built on the ground instead. This setup will, in turn, require a circulation system which ends up lowering the energy-saving efficiency. Meanwhile, PCM is suitable for thermal energy storage in solar heating systems due to its high thermal storage density and minimal temperature variation. Despite various studies focusing on improving the light absorption of PCM via the addition of light absorptive materials, there was no quantitative measurement conducted to derive the solar energy conversion and storage efficiency. Hence, besides fabricating a PCM loaded with reduced graphene oxide (RGO), this study also built a new in-house experimental setup to carry out the crucial quantitative characterizations.
[the_sdg_impact] => Renewable energy is essential to reduce the emission of greenhouse gases and to overcome pollution. This implies the urgent need for a superior energy storage system. The PCM developed in this research could set new benchmarks for solar water heater systems, benefitting both the environment and its consumers. Therefore, it aligns with the targets of UNSDG 7: Affordable & Clean Energy.

[the_novelty] => This study disclosed a shrimp feed formulation, a seaweed-probiotic blend, which could help shrimps resist acute hepatopancreatic necrosis disease (AHPND). The seaweed-probiotic blend was a combination of Bacillus species and the red seaweed, Gracilaria sp. Through in vitro studies, the seaweed-probiotic blend exhibited a synergistic antimicrobial effect against the AHPND-causing V. parahaemolyticus strain. Consistent in vivo results were obtained whereby shrimps fed with the blend were able to survive under the presence of Vibrio parahaemolyticus strain. This environmentally-friendly shrimp feed showed promising potential as an alternative to the antibiotics used in shrimp cultivation.
[the_background] => The whiteleg shrimp (Litopenaeus vannamei) is a well-known cultured shrimp. However, shrimp production was greatly reduced when AHPND caused mass mortality in the shrimp culture. Although antibiotics and probiotics are commonly used in controlling this bacterial shrimp disease, excessive use of antibiotics could adversely affect human health and environment. In developing natural alternatives to replace antibiotics, probiotics are known to be a suitable candidate. On the downside, the probiotics used are generally not of shrimp origin and, thus, reduce the efficiency of the probiotics in protecting the shrimps from pathogen infection. Meanwhile, the red seaweed, Gracilaria is a popular feed additive in Asia owing to its antibacterial effect. To have the best of both, this study investigated the antimicrobial effect of the combination of probiotics and seaweed against AHPND-causing V. parahaemolyticus. This combination has been shown to increase the survival of shrimp when the pathogens are introduced in the laboratory culture.
[the_sdg_impact] => Seafood prices keep soaring due to the increasing consumer demand. Reducing shrimp mortality due to bacterial diseases can improve shrimp supply in the market and, hence, provide high-quality and safe proteins to people. By proposing a sustainable method to lower shrimp mortality, this study contributes to the realization of UNSDG 2: Zero Hunger.

[the_novelty] => This study has successfully identified two antioxidant peptide sequences from jackfruit seeds. Both peptides, JFS-1 and JFS-2, exhibited protein protection potentials, whereas only Peptide JFS-2 displayed antioxidant activity. The antioxidant properties of Peptide JFS-2 were further investigated against different pH, temperature, and gastrointestinal digestion. Results indicated that Peptide JFS-2 was a suitable candidate to be used as a food preservative agent. Future studies on the peptides may map their antioxidant properties to a wider range of industrial applications.
[the_background] => Jackfruit seeds contain higher protein contents compared to the pulp. However, the antioxidant peptides derived from jackfruit seeds have yet to be identified. On the other hand, bioactivities were observed in protein hydrolysates and bioactive peptides derived from natural sources. Therefore, this study attempted to identify and examine the bioactive peptides extracted from jackfruit seeds. Results indicated that the peptides were potential antioxidants. These findings paved the path for future studies exploring stronger natural antioxidants.
[the_sdg_impact] => Studies have shown that various serious diseases (e.g., cancers) could be prevented by having a diet rich in antioxidants, primarily provided by fruits and vegetables. Furthermore, such a diet is unlikely to cause any severe side effects. By highlighting the possibilities and feasible ways to benefit from antioxidants in fruits, this study well aligns with UNSDG 3: Good health & well-being.

[the_novelty] => The study identified several extracts from 8 plants with strong antiviral activity and different action modes against the Chikungunya virus. These include preventing virus entry, reducing or killing virus propagation, or even preventing further spread of the virus in the host. The modes of action were predicated by plant species and type of extractant. Infected African monkey kidney epithelial cells were used to conduct in vitro studies by applying concurrent and non-concurrent sample introduction modes. In the concurrent mode, it was observed that more extracts exhibited strong antiviral activity. Future studies should focus on the isolation of bioactive compounds as well as the mode of action.
[the_background] => Chikungunya virus spreads through the bite of infected Aedes mosquitoes. Despite being present in 114 countries and territories, there is still no effective remedy to fight the Chikungunya virus. Medicinal plants are valuable for their phytochemicals. Furthermore, they are well-known for their antiviral activities, which could tackle diseases including influenza, human immunodeficiency, and dengue virus. To address the urgent need for anti-chikungunya virus agents, this study aims to evaluate 132 extracts from 21 species of medicinal plants (from Malaysia) for antiviral activity against the Chikungunya virus. These findings implied that the full potential of medicinal plants has yet to be unveiled.
[the_sdg_impact] => Chikungunya virus was first described in the 1950s, but no licensed vaccine or specific drug has been developed to overcome the virus. Hence, there is no vaccine or specific antiviral treatment available to date. The output of this research serves as significant progress to meet the demand. Such an attempt to combat infectious diseases aligns well with the targets of UNSDG 3: Good health & well-being.

[the_novelty] => This study has successfully synthesized Z-scheme N-BiOBr/NiFe2O4 nanocomposites which acted as photocatalysts under visible light. The highest photocatalytic activity was achieved when the nanocomposite contained 15%wt of NiFe2O4. Upon 60-min irradiation, the N-BiOBr/ NiFe2O4-15 nanocomposite removed 95.9% phenol and 100% Cr(VI). Besides being magnetically separable, the nanocomposite photocatalyst could be reused up to five successive runs without compromising its catalytic efficiency. These results indicated that N-BiOBr/ NiFe2O4-15 is a new promising catalyst for environmental and energy applications.
[the_background] => Water pollution has been an alarming side-effect owing to rapid development and industrialization. The pollutants mainly comprise organic compounds and heavy metals. Past studies show that BiOBr semiconductor is a potential photocatalyst whereby its response range could be improved via nonmetallic species doping. Meanwhile, NiFe2O4 ferrite is a popular photocatalyst for which its photocatalytic efficiency can be enhanced via coupling with semiconductor materials to form Z-scheme heterojunction. Since there is no existing literature from the past that has focused on the coupling of NiFe2O4 with N-BiOBr, this study aimed to synthesize N-BiOBr/ NiFe2O4 nanocomposite and explore its potential in removing organic pollutants and heavy metals. This serves as a good reference for future studies related to advanced photocatalysis technology for environmental and energy applications.
[the_sdg_impact] => WHO foresees that, by 2025, half of the world’s population will be living in water-stressed areas. Therefore, it is of utmost importance to develop new technologies to facilitate water sanitation and ensure a sustainable supply of clean water, which is also a source of affordable and clean energy. With the newly developed photocatalyst, this study contributes to improving water quality via pollution reduction (UNSDG 6: Clean Water & Sanitation).

[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => This study demonstrated the extraordinary antibacterial effect of honeydew honey produced by Heterotrigona itama stingless bee. The honeydew honey exhibited antibacterial activity, including inhibitory and bactericidal effects against antibiotic-resistant strains, such as Staphylococcus aureus and Escherichia coli, in in vitro studies. Such prominent antibacterial effect of stingless bee honeydew honey was due to the interactive actions of hyperosmolarity, acidity, hydrogen peroxide, and phytochemicals together in honey. Compared to honey bee honey, stingless bee honey showed a higher success rate in bacteria inhibition, which can be further enhanced when combined with antibiotics. Due to its superior antibacterial properties, H. itama stingless bee honey is a promising natural remedy for treating bacterial infections. Hence, this product can be considered and promoted as a potential wound dressing in the health care sector.
[the_background] => Past studies reported that the antibacterial effects of honeydew honey are more superior to that of blossom honey. However, to date, the antibacterial potential of honeydew honey produced by Heterotrigona itama stingless bees from Malaysia is still ambiguous. Furthermore, only two types of honey (i.e., manuka honey and Revamil honey) are approved for medicinal use to treat infections. Thus, this study aimed to determine the potential of H. itama stingless bee honeydew honey as an antibacterial agent. So far, the studies on Malaysian stingless bee honey, especially honeydew honey, are rather limited. Hence, this investigation is useful to provide information about the antibacterial properties of this honey.
[the_sdg_impact] => As bacteria keep evolving to resist antibiotics, WHO has identified a list of bacteria for which new antibiotics are urgently needed. Honey is well-known for being an effective natural antibacterial food. Apart from being a sweetener, findings show that H. itama stingless bee honeydew honey can be promoted as a health-promoting food. With this achievement, this study supports the research and development of medicines for communicable and non-communicable diseases (UNSDG 3: Good health & well-being).

[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => This study introduced a multi-criteria decision-making (MCDM) method, known as the integrated entropy–fuzzy VIKOR model, which was feasible in assessing the financial performance of construction companies. Using this model, ECONBHD was identified as the best construction company in Malaysia in terms of financial performance. Current ratio (CR), debt to equity ratio (DER), and debt to asset ratio (DAR) were the most significant financial ratios which determined the financial performance. With its proven effectiveness, the integrated entropy–fuzzy VIKOR model could be applied in other economic sectors and be extended to other MCDM problems, such as supplier selection.
[the_background] => The construction industry in Malaysia has been making significant contributions to the country’s economic growth. However, the COVID-19 pandemic has caused major disruption to most construction projects, which in turn affected the financial performance of construction firms. Therefore, during this period, precise financial performance evaluation is essential to help the construction companies make proper decisions. The VIKOR model has been commonly used in evaluating financial performance. Despite that, it has drawbacks, especially in setting decision criteria weight. To date, there is no study conducted to investigate the financial performance among construction companies by integrating entropy and fuzzy approaches into the VIKOR model. To address the gap, this research proposed an MCDM model, known as entropy–fuzzy VIKOR model, to evaluate and compare the financial performance of several construction companies.
[the_sdg_impact] => Uncertainties, such as the COVID-19 pandemic, are influential in decision-making processes that directly affect the performance of businesses. Considering such uncertainties, a multi-criteria decision-making method is needed to accurately evaluate the financial performance of companies. The integrated entropy–fuzzy VIKOR model has been proven to be feasible for such a purpose. Thus, this study achieves UNSDG 9: Industry, Innovation & Infrastructure through enhancing scientific research

[video] =>
[the_novelty] => This study discovered the ability of seaweed (Gracilaria changii) extract in protecting the reproductive system of mammals from the potential adverse effects of bisphenol A (BPA). Aqueous extraction of G. changii exhibited superior antioxidant properties, surpassing that of methanol and ethanol extraction approaches. Through in vivo studies using mice exposed to BPA, improved uterine development and chances of conceiving were among the remarkable findings reported. Future studies should focus on identifying the specific bioactive compounds from this aqueous extract of G. changii to further explore its mechanism of action in counteracting the BPA at the molecular level.
[the_background] => Gracilaria changii is a type of seaweed that is often used in food production. Besides being rich in nutrients crucial for human reproduction, G. changii is also known as a strong antioxidant. Meanwhile, plasticizer bisphenol A (BPA) was proven to cause oxidative damage to the human reproductive system and pregnancy. Hence, this study was conducted to investigate the potential of G. changii extract in mitigating BPA-induced adverse effects on female reproductive function. The potential of G. changii extract as a protection against BPA was proved. These results are valuable in overcoming conceiving problems associated with plasticizer toxicity.
[the_sdg_impact] => The global fertility rate has halved over the past 50 years (ourworldindata.org). This phenomenon is partially attributed to a hostile environment. By developing an effective solution to counter the negative effect, this study fulfills UNSDG 3.9 in substantially reducing the number of illnesses from hazardous chemicals.

[the_novelty] => This study reported how refugee children perceived their family lives and coped with life as a refugee in Malaysia. The Collage Life-Story Elicitation Technique (CLET) and a discovery-oriented narrative approach were applied to interview 25 refugee children in Kuala Lumpur. Emotionally, these children felt isolated, lonely, and powerless. To them, a family carried the significance of both vulnerability as well as a source of strength. Besides receiving help from enabling adults and teachers, their coping mechanisms included self-empowerment by being brave and independent. Future studies could explore further insights by engaging these interviewees through focus groups and providing them with better welfare.
[the_background] => Refugees in Malaysia are marginalized and have no legal rights or protection. Furthermore, the majority of the refugee children have no access to education and are vulnerable to behavioral problems, mental health problems, and substance abuse. Meanwhile, research that focuses on the experiences and perceptions and the coping mechanisms of refugee children in Malaysia is rare. Thus, to improve the well-being of refugee children, this study was designed to fill up the existing knowledge gap. The research outcome proves that CLET is a potential eco-systematic approach to act as a key to better understanding the perception and emotion of refugee children in the process of rendering help.
[the_sdg_impact] => Refugee children in Malaysia are often marginalized in society, making them vulnerable and requiring special assistance in meeting their educational needs, mental health care, and socio-emotional well-being. Despite their status, the government should pay attention to their well-being to ensure healthy and inclusive development of the country. By sharing crucial insights about refugee children, this study aligns with UNSDG 3: Good health & well-being.

[the_novelty] => This study used biomass from oil palm empty fruit bunch (EFB) to produce a highly efficient solid acid catalyst for biodiesel production. Results proved that the activated carbon (AC) extracted from EFB, when sulfonated by 4-benzenediazonium sulfonate (4-BDS), provided the highest biodiesel yield when calcined at 200 oC. Under optimum esterification conditions of 7 hours and 20 wt.%, the proposed catalyst was able to churn out the highest biodiesel yield, 98.1%. Moreover, synthesizing such highly effective catalyst from low-cost biomass waste is an environmentally friendly solution. Potentially, the proposed technique would lower the production cost of biodiesel and, in the long run, reduce the energy cost in the country.
[the_background] => As fossil fuel reservoirs continue to deplete at an alarming rate, biodiesel is highly sorted after as an alternative energy source. Current biodiesel production is still relatively expensive compared to fossil fuels since existing biodiesel plants largely operate using ineffective catalysis technology with poor yield. To overcome these limitations, this study investigates the synthesis of a biomass-based heterogeneous acid catalyst. Ultimately, such an approach aims to be more cost-effective than the conventional methods and more environmentally friendly.
[the_sdg_impact] => In 2015, the bio-economy sector started to bloom with the production of second-generation biofuels finally achieving commercial scale. Following such progress, developing countries are faced with a new set of market opportunities and policy dilemmas to enhance their usage of biomass, which can be transformed into more valuable products. Coincidentally, in 2015, a set of 17 Sustainable Development Goals were announced by the United Nations addressing pressing issues of society, economy, and environment. The proposed biomass-based heterogeneous acid catalyst promises to expand existing low-efficient catalyst technology for supplying modern and sustainable energy services. At the same time, making the production of biodiesel more affordable with the environmentally friendly catalyst. (SDG 7: Affordable and clean energy)

[video] =>
[the_novelty] => This study proposed a new computational framework for cancer prediction and classification called Significant Directed Walk (SDW). The framework was developed to refine the search direction and parameters in the existing directed random walk (DRW). This new genetic network allows the algorithm to study the nodes by comparing the gene expression value among the genes. Results showed that the SDW is able to perform better in terms of cancer prediction and classification sensitivity, with its accuracy reaching 95.03%. By adopting this proposed framework, the rate of early cancer detection can be improved significantly, in the long run, increasing the survival rate of the patients.
[the_background] => At present, the cancer prediction and classification tools are less accurate and sensitive and time-consuming as the screening process is not targeted. Moreover, the poor reference data pool limits the ability of the existing directed random walk (DRW) tool. Therefore, there is a demand for an improved DRW framework to identify more cancerous genes with higher accuracy in cancer classification of gene expression data. Hence, this study designs an improved and novel framework to identify the exact genes within the genome that might turn into cancer carriers through the gene expression value.
[the_sdg_impact] => According to WHO, cancer is a leading cause of death worldwide, accounting for nearly 10 million deaths in 2020 alone. Early detection is among the most effective way to increase the survival rate of cancer patients. Thus, there is a dire need for technology upgrades and machine learning to shorten the time taken to screen for cancer markers, detection, and classification. This study addresses these needs and, upon implementation, would contribute to the long-term reduction of the premature mortality rate of cancer patients as envisioned in UN SDG 3: Good health and well-being.

[video] =>
[the_novelty] => Theoretically, psychological ownership (PO) is essential to motivate users to adopt technology through their beliefs such as perceived usefulness and perceived ease of use. However, this study showed that the influences on teachers' continued reliance on technology might be more complex than that. Nevertheless, the results indicated that perceived ease of use (PEU) is a stronger reason for teachers to embrace cloud-based virtual learning environments than perceived usefulness (PU) despite teachers having gained experience using it and the platforms being user-friendly. Therefore, the education ministry and school authorities should consider catering to the teachers' readiness and need to encourage the use of cloud-based virtual technology in classrooms and learning widely.
[the_background] => Malaysia invested over 13 years with an estimated cost of RM1.5 billion (about US$500 million). The country is also recognized as one of the pioneers in Asia to initiate a nationwide cloud-based learning environment. However, literature proved that such technology is underutilized despite the strategies and policies designed to drive the adoption. Moreover, most past literature focused on the adoption behavior among students, university educators, or pre-service teachers. Little is known from the perspective of practicing school teachers. Hence, this study examines the factors driving teachers to develop psychological ownership towards a cloud-based virtual learning environment and their intention to continue. The outcome intends to understand the underutilization of such technology in education for developing countries facing similar challenges.
[the_sdg_impact] => Education is among one of the significantly affected sectors amidst this COVID-19 pandemic. Teaching and learning experiences had to instantly adopt and adapt to virtual learning environment leaving students and teachers to struggle, especially in developing and under-developed countries. Apart from the readiness in terms of infrastructure, the willingness of teachers to utilize these facilities and continue using them even after physical classes resume needs to be understood. Therefore, the insights provided by this study would benefit policymakers and school authorities to re-evaluate teachers' training needs to embrace a virtual learning environment to provide the best 21st century learning experience for students.

[the_novelty] => Lignin extracted from empty fruit bunches (EFB) can undergo hydrothermal treatment with urea to produce a stable photocatalyst that degrades dye molecules. The study used this technique to develop photocatalysts, nitrogen-doped carbon quantum dots (NCQDs), to treat water sources polluted with harmful organic dyes. By including NCQDs, 97%-98% of methylene blue and malachite green dyes were degraded within 120-180 minutes of sunlight exposure compared to only 59% of degradation without the catalyst. Furthermore, findings also showed that the number of cycles to repeatedly used photocatalyst could go up to 15 cycles with approximately 70% decolorization efficiency. In conclusion, the proposed NCQDs are not just effective water treatment substances but are also a greener option to reduce oil palm waste.
[the_background] => Synthetic organic dyes used in textile industries are major sources of water pollution. Dyes such as methylene blue and malachite green are highly toxic and harmful for marine life and humans. Moreover, the presence of dye molecules in the water stream may prevent sunlight penetration into the water, affecting the photosynthesis of aquatic plants. Therefore, a stable and reliable catalyst is required to treat the wastewater before discharging. Separately, empty fruit bunch (EFB) are oil palm waste that is largely discarded. The rich molecular make-up of this waste has a huge potential to be converted into carbon-based nanoparticles and catalysts. Thus, this study proposed nano-photocatalyst derived from biomass as a safe solution to decolorize the dye molecules in the water streams.
[the_sdg_impact] => A 2020 article published by CNN highlighted devastating environmental and health effects caused by textile dyeing practices of the global fashion industry. Nations like Bangladesh, highly dependent on the garment sector as their source of income, face severe pollution threats as the industry’s wastewater largely gets dumped directly into their rivers and streams. Therefore, this study is useful to substantially reduce such water pollution threats and minimize their adverse impacts on human health and the environment through an environmentally sound management technique.

[graphic_abstract] => https://iesresearch.solutions/wp-content/uploads/2022/05/1-s2.0-S0944711321001665-ga1_lrg.jpg
[figures] =>
[video] =>
[the_novelty] => This study provides evidence of the counter-effect of a common botanical product when consumed by hypertension patients on medication. One of the major catechins found in green tea extract is known as epigallocatechin gallate (EGCG). Due to the established blood pressure lowering effects of green tea, it is not surprising that hypertension patients might consume highly concentrated or purified EGCG along with their medication with or without their physicians’ knowledge. However, based on a 14-day observation of continuous consumption of herbal supplement with EGCG content as low as 10 mg/kg b.w. showed that EGCG interfered with the effectiveness of nadolol, an antihypertensive drug commonly prescribed to hypertensive patients. Such reduced drug effect results from RNA expression dysregulation of the key nadolol transporters (Oatp 1a5, Oct1and P-gp). Thus, proving an unfavorable herb-drug interaction and outcome among the hypertension patients prescribed nadolol. Essentially, these insights are useful for physicians to advise their patients, adjust nadolol prescription dosage, or prescribe alternative drugs for green tea consumers with hypertension.
[the_background] => Statistics showed that less than 13% of hypertensive patients achieved blood pressure control (<140/90 mm Hg) while on treatment. Such a scenario results in physicians either prescribing more medication or increasing the dosage. In the long run, these actions would potentially contribute to medication and economic burden as well as increase the risk of drug side effects among the consumers. Meanwhile, herbal or ‘natural’ medicine has been gaining popularity among patients with various ailments. Particularly, green tea consumption is highly favored due to its extensive therapeutic effects. Although one of its medicinal properties is to lower blood pressure, its effect on hypertension patients on antihypertension medication is unclear. Therefore, this study investigates the effects of a widely available herbal supplement, EGCG, on the blood pressure of those given nadolol and the biological mechanisms involved.
[the_sdg_impact] => According to WHO, close to 1.3 billion adults aged 30-79 years worldwide have hypertension, and it is a major cause of premature death. Adopting a healthy lifestyle is among the most recommended hypertension management techniques, while many patients trust herbs or ‘natural’ medicine to do the trick. Therefore, it is crucial for physicians and healthcare personnel to advise patients on medication to monitor the supplements or herbs that are not prescribed yet being consumed. In extension, such effort would improve the drug effectiveness among hypertension patients on medication and, in extension, reduce premature mortality of hypertension-related cardiovascular diseases (SDG 3: Good health and well-being).

[research_footprints] => compressive strength; non-destructive test (NDT); elastic wave; air-entrained rubberized concrete

[figures] =>
[video] =>
[the_novelty] => This study suggested adopting the non-destructive test (NDT) as a more effective method to assess concrete strength during the hardening process. Among the significant improvement observed by adopting this testing method is the amount of time needed. Results indicate that the test is able to reduce the time taken to 1 day, as compared to the conventional process, which requires 28 days. Moreover, this approach is also resource-efficient as it does not involve the specimen being demolished during testing. Last but not least, the findings proved that wave amplitude and velocity are crucial to determining the compressive strength development of air-entrained rubberized concrete.
[the_background] => In recent years, there has been a steadily increasing demand for rubberized concrete due to its lightweight, strength, elasticity, ductility, and energy and force absorption potentials. Air-entraining agents have been introduced in rubberized concrete to further lengthen its lifespan and durability. However, there has been inconsistency in terms of the compressive strength of air-entrained rubberized concrete compared to conventional concrete. The test required to determine the compressive strength and properties is known to be tedious and time-consuming. Therefore, this study proposes a more efficient and reliable assessment of rubberized concrete specimens, particularly in completed buildings.
[the_sdg_impact] => Over the years, green construction has been receiving more attention. Concrete production is slowly being altered to be greener through the use of scrap tires to produce rubberized concrete. To ensure the shift to an environmentally sound material does not compromise the safety and durability of the buildings constructed, a reliable testing method is necessary. Hence, the findings of this study would serve as a reference to enhance and upgrade the technological capabilities of the construction industry. (SDG 9: Industry, innovation and infrastructure)

[the_novelty] => The study proposed using deep learning technology to design a highly accurate skin cancer diagnosis tool in the form of a smartphone app. In order to optimize the functions of the app, a thorough analysis was performed using different computational intelligence models on various models of smartphones, screen resolutions, and android versions. As a whole, the proposed technology is set to design a cheap, user-friendly, and reliable smartphone camera-based app capable of eliminating the need for sophisticated external sensor tools. Through such an app, the chances of early skin cancer detection can be improved, and physicians' inconsistent manual diagnosis could be avoided.
[the_background] => One of the most effective ways to battle cancer is through early detection. At present, early detection of skin cancer is highly reliant on experts such as doctors and dermatologists. However, past literature has proven that the conventional method such as manual inspection using ABCDE criteria has various limitations, namely subjectivity and inaccuracy, owing to the varying experience level of dermatologists and irregular characteristics of malignant skin lesions. Thus, leading to the condition being missed or misdiagnosed. Therefore, this study aims to replace the current skin cancer early detection method with object detection and deep learning technology by integrating the ABCDE criteria. Since smartphones or smart devices have seamlessly been integrated into our daily routine, this study proposes the development of a smartphone app as a potential early diagnostic tool.
[the_sdg_impact] => According to the World Health Organisation (WHO), there has been a significant rise in the cases of malignant skin cancer over the past decade. Early detection of skin cancer is required to classify symptoms so that attending dermatologists and clinicians can recommend effective disease control measures. Presently, the computational capability of smart handheld devices is feasible to be integrated with object detection technology. As a result, the coupling of smartphones and deep learning could aid in detecting and classifying skin lesions. A handy diagnostic tool with such capability would increase the chances of early detection, thus improving the survival rates of the patients by having the disease treated sooner.

[research_footprints] => obesity; risk factors; psychological; adults; Malaysia
[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => This study provided evidence of potential psychological determinants that cause obesity among men and women. Consistent with past literature, the results proved that women are more likely to be obese than men. More specifically, married, middle-aged Indian women with only school-level education face a higher risk of being obese. Among the contributing psychological factors in women for such an outcome is the stressful life events encountered and their quality of life. On the other hand, men facing perceived stress or having suicidal ideation have higher chances of being obese. To the authors’ knowledge, this study provides primary evidence of the association between psychological determinants and adult obesity. Potentially, policymakers could use the findings as a reference to address psychological needs when designing effective obesity prevention strategies in the community.
[the_background] => Obesity has been commonly linked to the risk of developing various major illnesses and psychological effects. However, the understanding of how psychological factors could lead to obesity remains unclear. In Malaysia, obesity prevalence among adults has shown a four-fold increase between 1996 and 2015. Being highly populated with working adults, the high incidence rate of obesity in Selangor is concerning as compared to other states. Therefore, this study aims to understand the underlying factors and psychological determinants causing adults of Selangor to be obese or overweight.
[the_sdg_impact] => According to Global Burden of Disease 2019, a high body mass index is among the top risk factors contributing to the development of non-communicable diseases (NCDs). In the global status report on NCDs, WHO recorded 39% of adults to be overweight, and the prevalence is expected to rise by 2025. In the Malaysian context, it recorded the highest obesity rate in adults compared to other Southeast Asian countries. Therefore, the findings of this study would benefit policymakers and healthcare personnel to understand the socio-demographic variables and psychological factors leading to poor health conditions among Malaysians. Such insights would contribute to effective prevention and treatment strategies when managing obesity-linked NCDs (SDG: Good health and well-being).

[the_novelty] => Unlike existing sensors that are limited to only detecting air pressure, this study designed a novel structure that combines the antenna and pressure sensing functionalities into a single piece. The proposed liquid dielectric resonator antenna (LDRA) can achieve high compactness as it uses an organic solvent, acetonitrintrile, with a low loss tangent at 2.4 GHz. Findings indicate that the antenna gain of the design is at least 2 dB higher than that of the commonly suggested water LDRA. Additionally, the soft-lithography technique used allows rapid prototyping. In short, this proposed design promises a dual-sensing functionality with improved sensitivity and circuit footprint. It also reduces material costs and can potentially be expanded into wearable devices that require higher power consumption.
[the_background] => Pressure sensors are essential for monitoring and controlling, particularly in biomedical technologies and auto industries. One of the limitations of presently available commercial sensors is the restricted mobility as they require wires and batteries to operate. Moreover, the existing rigid containers also limit the functions of the antenna structure as a pressure sensor. Hence, requiring a more flexible and stretchable material to improve the storage of electrical energy that can respond to the change of stimuli. As a solution, this study proposed a wireless power technology that combines both wireless receivers and sensors as an alternative.
[the_sdg_impact] => Pressure sensors play a huge role in the medical and healthcare sectors, especially among ventilator and respiratory manufacturers. Over the decade, there has been a noticeable need for flexible pressure sensors, preferably low-cost, portable, and light-weighted. Besides, the 9th UN SDG, Industry, Innovation and Infrastructure, also encourages the development of quality, reliable, sustainable, and resilient infrastructure to support the evolving community and technological needs. Hence, in alignment with such goals, the materials and design of the liquid dielectric resonator antenna (LDRA) proposed promises to improve the air pressure sensing capability by overcoming the limitations of existing models.

[figures] =>
[video] =>
[the_novelty] => While attempting to produce superheavy nuclei (SHN) with Z = 119 – 122 in the fusion-evaporation reactions within the dinuclear system (DNS) model, this study discovered that 44Sc+252Es was the optimal combination in the 3n channel with a cross-section of 3 pb. Maximum cross-sections of the evaporation residues (ER) were found in the (2-5)n evaporation channels, i.e., approximately 1 pb in the 3n evaporation channel. The results were in good agreement with the experimental data from Dubna. The SHN were produced by bombarding the actinide nuclides with the transition elements from Period 4. Since the orientations were the main determining factor of the ER cross-sections, all possible collision orientations were included by applying the Monte Carlo approach in the nucleon transfer process. Using these results as a reference, future investigations should be conducted to uncover other potentially promising reaction mechanisms to produce SHN.
[the_background] => SHN (Z ≥ 106) are given rise by the strong binding shell effect when the Coulomb repulsion is overcome. The initial synthesis of SHN nearly half a decade ago involved multinucleon transfer reactions in collisions of two actinide nuclei. Meanwhile, the formation dynamics of SHN in massive fusion and multinucleon transfer reactions have been the main focus. Hence, systematic studies on the production of SHN are needed to predict the reaction mechanism, including optimal projectile-target combinations. This study conducted a comprehensive study on the fusion dynamics of the formation of superheavy nuclei within the DNS model by adopting the Monte Carlo approach. The findings shed some light on the fusion-evaporation reactions applied for synthesizing SHN with Z = 119 – 122, bringing SHN research one step closer to discovering “island of stability.”
[the_sdg_impact] => Superheavy elements (SHE) are rare naturally and only exist briefly under highly controlled circumstances. Their common applications include smoke detectors (americium), neutron radiography and neutron interrogation (curium and californium), and nuclear weapons (plutonium). Thus, besides exploring the concept of “magic numbers” and “island of stability,” a better understanding of the formation mechanism of SHE could lead to a significant advancement of nuclear technology. By focusing on the synthesis of various SHN via fusion-evaporations reactions, the output of this in-depth study contributed to the progress of SHN synthesis. Therefore, it fulfilled UNSDG9: Industry, Innovation & Infrastructure.

[the_novelty] => As an initial step to fully leverage the available radioactive ion beam facilities and resources, this study developed a collinear laser spectroscopy (CLS) apparatus combined with an offline laser ablation ion source at Peking University. The CLS was commissioned using a bunched stable calcium ion beam being accelerated up to 20 keV, with a pulse width of approximately 10 µs. This CLS, integrated with the ion source and an anti-collinear laser system, has enabled high-resolution measurements of the hyperfine structure spectra of stable 40,42,44,48Ca isotopes. With its successful commissioning, the CLS is ready for laser spectroscopy measurement of unstable nuclei at radioactive ion beam (RIB) facilities in China, paving the way for further developing higher-sensitivity collinear resonance ionization spectroscopy techniques.
[the_background] => The fundamental properties of atomic nuclei, such as nuclear spins, magnetic dipole moments, electric quadrupole moments, and mean-squared charge radii, are the essential experimental observables in studying the exotic nuclear structure and nucleon-nucleon interactions. Despite having various experimental methods to measure these nuclear properties, CLS is one of the most sophisticated experimental techniques available to simultaneously measure these properties in a nuclear-model independent way. This is realized by probing the subtle hyperfine effects, only as small as one part in a million compared with the total atomic transition frequency, resulting from the interaction between the atomic nucleus and surrounding electrons. CLS system has been set up in various RIB facilities worldwide to explore the exotic structure of radioactive isotopes. Lanzhou's HIRFL-RIBLL and Beijing's BRIF are among the uprising RIB facilities with short-lived isotopes ready for in-depth nuclear structure studies. The CLS, however, has not yet been involved in nuclear physics research at the domestic RIB facilities so far. The CLS apparatus developed by this study thus represents new opportunities for advanced studies of the nuclear properties of unstable nuclei at the RIB facilities in China.
[the_sdg_impact] => The unexpected new phenomena of unstable nuclei have been continuously unveiled when the study reaches the exotic isotopes far from the beta-stability line. By exploring short-lived nuclei produced artificially at RIB facilities, this study helps scientists understand the rich, complex, and even unexplored exotic structure of atomic nuclei and the nucleon-nucleon interactions. Ultimately, this would unveil the puzzle: where and how heavy matter forms in the universe (UNSDG 9: Industry, Innovation & Infrastructure).

[the_novelty] => This study developed HOTCAP, a free, user-friendly, and interactive software, for simultaneous measurement of 3D bunch-by-bunch position and charge from the waveform of a high-speed oscilloscope. Being able to operate on Windows 10, HOTCAP could also output injection transient analysis, bunch response function reconstruction, and turn-by-turn beam analysis. Its visual interface was developed based on PyQT5. HOTCAP was coded using Python on the backend, and its architecture comprised the user interface (UI) module, the calculation module, and the input-output (IO) module. Future studies shall improve the algorithm to eliminate HOTCAP’s current need for a constant bunch length.
[the_background] => Bunch-by-bunch measurement includes transverse position measurements, longitudinal phase measurements, charge measurements, beam size measurements, and emittance. Among these, position measurement is the most important and common technique carried out via the random phase sampling method using a digital oscilloscope. However, since a large amount of input data and complex digital signal processing are involved, there is a high demand for comprehensive data processing algorithms or corresponding data processing software packages to be used in high-speed oscilloscope-based 3D bunch charge and position measurements. In order to fulfill the need, researchers from Shanghai Synchrotron Radiation Facility (SSRF) Beam Instrument Group have successfully developed HOTCAP (a visualization software package) to serve as an online measurement system that can simultaneously measure the bunch-by-bunch 3D position and strip the refilled charge signal. Other accelerators will benefit from this software as soon as the researchers share the source code in the near future.
[the_sdg_impact] => SSRF strives to uphold its potential and reputation as a world-class state-of-the-art beam facility. To help achieve that, this research developed the first mature and free software package for high-speed oscilloscope-based three-dimensional (3D) bunch charge and position measurement. The output contributes to the advancement of beam diagnosis technology, which enhances the operation of synchrotron radiation facilities, realizing UNSDG 9: Industry, Innovation & Infrastructure.

[the_novelty] => This research revealed the in-depth design (both hardware and firmware) of the first and second compact nanosatellite gamma-ray detectors built for the Gamma-Ray Integrated Detectors (GRID) mission. The detector comprised four Gd2Al2Ga3O12 : Ce (GAGG:Ce) scintillators coupled with four silicon photomultiplier (SiPM) arrays, and the detector’s gamma-ray detection efficiency ranged between 10 keV and 2 MeV. The first and second detectors were launched into Sun-synchronous orbits with an altitude and inclination of 500 km 97.5 ° and 97.3 °, on October 29, 2018, and November 6, 2020, respectively. The detectors managed to accumulate data for more than 300 hours of on-orbit observation. For further context, detailed calibration of the detector using both simulations and experiments will be reported elsewhere in the near future.
[the_background] => The GRID mission is a project which bears the main objective to involve students in monitoring the transient gamma-ray sky in the local universe and in accumulating a sample of gamma-ray bursts (GRBs) associated with gravitational waves (GWs). The first detector was launched into a Sun-synchronous orbit on October 29, 2018. After the on-orbit functional and performance tests of the first detector, fewer hardware modifications and improvements have been made in the second detector. This paper shows the detailed design of the GRID detector, and the functionality and performance of this design have been verified by two launches. By sharing these significant details of the compact CubeSat gamma-ray detector, this study encourages and attracts students from multi-disciplinary to participate in GRID so as to grow their hands-on experience in astrophysics.
[the_sdg_impact] => Astrophysics is a subject area that often involves multi-disciplinary collaboration in developing hardware and data. Hence, having a well-developed research facility and infrastructure is essential to let students and researchers deploy their output in a real environment. Besides sharing the detailed hardware and firmware design, this study also motivates students to participate in the GRID mission by describing how the latter empowered the study's progress. Therefore, the outcome of this study aligns well with UNSDG 9: Industry, Innovation & Infrastructure by supporting the development of research and technology.

[the_novelty] => This study explores a range of construction mechanisms with different conditions to improve present 2D material performance. As a breakthrough, a new strategy to construct Fe,N-codoped hierarchical porous carbon nanosheets (Fe-N-HP-CNS) by using 2D Fe-Zn layered double hydroxides (Fe-Zn-LDH) was developed. The proposed multifunctional templating strategy simplifies the synthetic route and yields well-defined 2D carbon nanosheets with a hierarchical porous structure and a functional carbon framework. Overall, the novel method promises an improved template functionality while eliminating the adverse effects and limitations of single-functioned conventional carbon nanosheet construction techniques.
[the_background] => 2D porous carbon nanosheets have desirable physical and chemical properties, including excellent electrical conductivity, superior chemical stability, and adjustable carbon framework. Hence, the materials have been widely used in electrochemical energy storage, catalysis, battery, water treatment, and many more. With that said, existing carbon nanosheet templates largely fit a single function. Moreover, the preparation processes are not only costly and complex, but also non-environmentally friendly. Therefore, this study looks into the synthesis process of carbon nanosheets by leveraging the 2D structure and potential multifunctional characteristics.
[the_sdg_impact] => 2D porous carbon nanosheets have become the recent most in-demand porous carbon due to the uniqueness of its structure and promising functionalities, potentially useful in various applications. Given the increasing requirements on applications in our current lifestyle, there’s a growing need for a simple and precise construction strategy of this ‘super’ material. Therefore, the novel approach developed in this study expands the functionality of 2D porous carbon nanosheets by improving resource-use efficiency and adopting a cleaner and greener construction mechanism (SDG 9: Industry, Innovation and Infrastructure).

[video] =>
[the_novelty] => This study developed an SP3-coupled global variance reduction (GVR) method, which brought the efficiency and accuracy of the Monte Carlo (MC) criticality calculation to a whole new level. The workflow of the SPN-based GVR involved MC global homogenization in determining global cross-sections, SP3 equation-solving to obtain the global flux distribution, and global weight windows approximation. Despite achieving a noteworthy milestone, this research aimed to enhance the GVR’s performance in the near future by involving rigorous SPN theory and an adjoint method for the SPN theory.
[the_background] => The design and performance of a reactor rely significantly on the reactor criticality calculation, which applies the MC method most of the time. Besides enhancing the overall efficiency and accuracy, variance reduction (VR) methods are crucial in maintaining the numerical stability of MC multi-physics simulations. The VR methods developed in the past (i.e. UFS, UTD, UVM) face limitations in terms of working principles, techniques, and validation. To fulfill the demand for a more superior reactor, this study proposed an SP3-coupled GVR that enhanced the overall precision of MC criticality calculation. This development could potentially improve the reactor shielding calculations, leading to a higher-performance reactor.

[the_novelty] => Is there any room to increase the accuracy of theoretical nuclear mass prediction? This study demonstrated that Light Gradient Boosting Machine (LightGBM) is a highly competent tool for improving the accuracy of theoretical nuclear mass and binding energy predicted. With respect to experimental binding energy, LightGBM’s refinement managed to reduce the root mean square deviations (RMSDs) by approximately 90%, 65%, 40%, and 60% in the liquid-drop model (LDM), Duflo–Zucker (DZ) mass model, Weizsäcker–Skyrme (WS4) model, and finite-range droplet model (FRDM) respectively. Consistent RMSD improvement was obtained compared to the 66 newly measured nuclei that appeared in the new atomic mass evaluation, AME2020. Besides that, the LightGBM-refined mass models also yielded single and two-neutron separation energies values that matched those derived experimentally. All it took for the LightGBM to work was the input of characteristic quantities like mass and proton numbers. Relevance analysis of input characteristic quantities for each mass model was carried out using SHapley additive exPlanations (SHAP) and valuable results were obtained for future improvement and development of various nuclear mass models.
[the_background] => Nuclear mass has been a crucial and challenging subject, especially for nuclei near the drip lines (i.e., the boundaries delimiting the zone beyond atomic nuclei decay). A Bayesian neural network (BNN) refinement is a promising approach for theoretical models to deduce nuclear mass with higher accuracy. On the other hand, a tree-based learning algorithm developed by Microsoft in 2016, known as LightGBM, shows upsides, including better learning capability, greater efficiency, and better accuracy. This puts LightGBM in an advantageous position to be applied in studies of nuclear mass. As an effort to verify the potentials of the LightGBM machine learning algorithm, this study deployed LightGBM in predicting the masses and binding energy of unknown nuclei. The reduced RMSDs obtained were an excellent validation of LightGBM’s value in nuclear mass studies, which could set a more refined direction for future research.
[the_sdg_impact] => The advancement of astrophysics and nuclear physics correlates with the level of knowledge in nuclear mass. Hence, a highly efficient machine learning method is needed to speculate the masses of unknown nuclides, especially superheavy and neutron-rich nuclides. This study validated LightGBM’s potential in nuclear mass studies and, consequently, indicated the importance of machine learning in the progress of astrophysics and nuclear physics. These fundamental findings are essential to facilitate future scientific research by leveraging the ever-evolving technological capability, which aligns with the visions of UNSDG 9: Innovation, industry, and infrastructure.

[the_novelty] => The distribution system of the power grid is affected by the high voltage fluctuation due to the solar PV systems. A grid-connected battery energy storage system is a potential solution. The study analyzed solar PV system voltage profiles and solar power output with four different module technologies at various locations in the free-standing installation method. The study concluded that voltage fluctuation is the highest during the day in both low and high load conditions. Future studies should evaluate the effects of weather and position of solar PV systems against the system’s voltage profile.
[the_background] => As more and more people adopt a greener lifestyle, the demand for solar panel reliance has increased in recent years. However, in the usage of solar panel-derived energy, voltage supply seems to fluctuate due to irregular sunlight availability. Such condition poses a negative effect on the power grid, especially the distribution network. Therefore, this study aims to quantify the voltage fluctuation for small-scale solar photovoltaic systems under different loading conditions, specifically voltage and solar power output. The potential solution for this would be a grid-connected battery energy storage system, which allows grid quality and reliability maintenance.
[the_sdg_impact] => The increasing adoption of solar power encourages the shift from the current system that uses fossil fuel, promoting cheaper and cleaner energy production. This study strongly associates with Goal 7: Affordable and Clean Energy and Goal 12: Responsible Consumption and Production of the UN’s Sustainable Development Goals (SDG) as the findings are useful for the relevant parties to take suitable actions in improving existing solar PV systems. Ultimately, serving as a good reference for institutions and countries intending to move towards sustainable energy and reduce their environmental impacts through solar power.

[the_novelty] => This study uses statistical and mathematical models to optimize cure characteristics of Natural Rubber/ EPDM (a type of synthetic rubber) blends. The proposed software identified the optimum mixing parameters (temperature, rotor speed, time) for adding maleic anhydride grafted EPM (MAH-g-EPM). As a result, the miscibility, and physical and rheological properties of the NR/EPDM blend were significantly improved. Thus, creating a more stable rubber blend by increasing the material resistance towards deformation. Such software and analytical technique enable future material characterization to be conducted efficiently across multiple parameters within a short period of time.
[the_background] => The blending of two or more elastomers (polymers with elastic properties) is common to obtain new materials with improved and superior properties compared to its original phases at a minimal cost. Applying a similar concept, rubber blends are frequently tested and created to produce newer and sturdier materials for various uses. Natural rubber/EPDM blends are by far the most prominent form of synthetic rubber in terms of performance and elasticity. However, the synthetic rubber blends have shown several mechanical property degradations due to poor compatibility. This study aims to provide suitable and effective cure characteristics of NR/EPDM blends for better miscibility and compatibility.
[the_sdg_impact] => Rubber is still widely used in automobile manufacturing along with many other industries for various purposes. According to a March 2021 BBC article, there still is a growing demand for rubber worldwide while there is a shortage in terms of supply. With lands being scarce to accommodate the expansion of rubber plantation, alternative methods are required to make up for the demand. As the use of synthetic rubber increasing, there is a need to constantly improve its quality and durability under minimum expenditure and production time. Thus, the findings of this study clearly promote the enhancement of scientific research to upgrade material production through a more sustainable and efficient use of resources (SDG 9: Industry, innovation and infrastructure).

[video] =>
[the_novelty] => This study demonstrated for the first time a spent coffee ground (SCG) film made of waste product from coffee beans as saturable absorber (SA) for wideband pulsed laser generations. The findings indicate that the fabricated SCG film modulator has a modulation depth, saturable intensity, and non-saturable absorption of 30%, 150 MW/cm2, and 28%, respectively. The fabricated SCG film modulator produced a highest pulse energy of 0.152 μJ and shortest pulse of 4.20 μs at the 1-μm region, which fits the expectations of pulsed laser performance. The SCG film modulator's ability to induce pulsed lasers at various regions, alongside its considerably simple fabrication process, may benefit diverse photonic applications.
[the_background] => Pulsed lasers have high pulse energy, with a pulse width that can be tuned up from a microsecond to hundreds of nanoseconds. The active method generation of pulsed lasers in the past is less desirable due to the size, cost, and handling challenges. Hence, passive techniques using modulators have been explored, and nanomaterials like graphene (a form of carbon) are highly preferred in producing such modulators. This study demonstrates the use of waste products from coffee grounds as bio-resources for carbon to synthesize graphene nanomaterials suitable for modulators.
[the_sdg_impact] => Global coffee production creates more than 23 million tons of waste per year. Coffee waste is an inexpensive and green alternative for nanomaterials production, which could be applied across various fields. As the pioneering study to utilize waste coffee grounds as bioresources to synthesize graphene nanomaterial for laser technology, it is a great example of enhancing and promoting environmentally sustainable material production with increased resource-use efficiency. Therefore, the study objectives align well with UN Sustainable Development Goal (SDG) 9, Industry, innovation and infrastructure.

[video] =>
[the_novelty] => In the past decade, the usage of stereoelectroencephalography (SEEG) to identify the epileptogenic zone in patients with drug-resistant epilepsy has increased. In this study, researchers used high-frequency oscillations (HFO) in SEEG to distinguish the common changes in the epileptic brain over the course of a seizure. The implementation involved the usage of 3D electrodes implant based on the SEEG methodology. As a result, the onset, propagation, and termination of seizure were identified by observing the high frequency brain waves. The overall change in wave frequency gives a complete map of HFO. Essentially, this HFO map could serve as a biomarker and improve surgical strategy to control/correct seizures with better accuracy and precision. Hence, these new insights would be useful references for researchers and physicians to advance existing epilepsy treatment outcomes.
[the_background] => To improve surgical outcomes, it is common to do a non-invasive evaluation prior to surgery to locate the epileptogenic zone (EZ). However, if the EZ is not readily identified, invasive electroencephalography is required. Therefore, it opens the possibility to produce biased data due to a lack of experience. In this study, researchers explore the usage of stereoelectroencephalography (SEEG) to identify ictal high-frequency oscillation (HFO) networks. The primary aim of the study is to develop a new approach for surgery or neuromodulation that may help physicians improve treatment modalities for epilepsy, including resection, cortical stimulation, and neuromodulations treatment that are responsive to network topologies.
[the_sdg_impact] => According to a 2019 report from the World Health Organization (WHO), an estimated 50 million people worldwide suffer from epilepsy, making it one of the most common neurological diseases globally. As presented in this study, it is notable that using high-frequency oscillations (HFO) in stereoelectroencephalography (SEEG) can identify the epileptogenic zone (EZ) in the brain. Resection of the areas of the brain where HFOs have been recorded gives a good postsurgical outcome. Thus, the finding of this study would help towards the realization of UNSDG 3: Good Health and Well-Being, which aims to ensure healthy lives and promote well-being for all ages, as well as UNSDG 9: Industry, Innovation and Infrastructure, for its application of research outcome to accelerate A.I.-based medical technology advancement.

[the_novelty] => This study verified the effectiveness of the upgraded CSNS Back-n neutron beamline detection system for neutron capture cross-section measurements using gold (197Au (n, γ)). The new setup included C6D6 detectors and Li-Si flux monitor, the pulse height weighting technique (PHWT) detection technology was used to analysis the data. The results proved that the 197Au (n, γ) reaction cross section measured with neutron energies ranging from 1 eV to 100 keV is consistent with the latest standard evaluations data. Meanwhile, the findings indicated a promising less than 2% statistical uncertainty for the 197Au (n, γ) reaction cross section measured. Therefore, it is evident that the CSNS Back-n neutron beamline facility enhancement proposed in this study would benefit future characterization and the study of synthesis of heavy elements.
[the_background] => Neutron-induced reactions have long been used to characterize and synthesize heavy elements. Such techniques have been inspired by the naturally occurring slow neutron capture process (s process) in stars. At present, most neutron capture cross section measurements only one capture criterion for the 197Au (n, γ) reaction with 2.5 MeV thermal neutron energy. Hence, this study proposed integrating C6D6 detectors and PHWT detection technology with the CSNS Back-n neutron beamline. The overall feasibility of the experimental setup was determined by cross-referencing the data with the standard neutron capture cross-section database.
[the_sdg_impact] => Neutrons have long played an essential role in engineering materials for nuclear reactors, along with material characterization. As the demand for electric energy grows, so does the demand for potential alternative energy production sources, one of which is nuclear power. Thus, there is a constant need to advance and enhance existing nuclear detection and imaging technology (UN SDG 9: Industry, innovation and infrastructure). The findings of this study could serve as a reference to improve the performance of the current Back-n neutron beamline facility for better heavy chemical elements characterization and data analysis.

[research_footprints] => Tungsten accumulation; Counter-NBI; Favorable B t; ELMy H-mode; EAST
[graphic_abstract] => https://iesresearch.solutions/wp-content/uploads/2021/11/NST_Article-15.jpg
[figures] => https://iesresearch.solutions/wp-content/uploads/2021/11/Tungsten-.png
[video] =>
[the_novelty] => Via experimental investigation on the Experimental Advanced Superconducting Tokamak (EAST), this study reported how the behavior of tungsten (in ELMy H-mode plasmas) could be controlled by neutral beam injection (NBI) and toroidal field (Bt). The concentration of tungsten in the plasma operation was successfully lowered by applying counter-NBI and favorable Bt. It’s crucial to prevent tungsten accumulation and keep tungsten concentration below 10–4 to avoid degradation of plasma confinement and periodic H–L transitions. Future in-depth studies could be carried out to better understand the implications of increased turbulent transport (during the co/counter-NBI phases) on the suppression of tungsten accumulation.
[the_background] => Despite being preferred for plasma-facing materials in fusion devices, tungsten tends to accumulate in EAST type-I ELMy H-mode plasmas. Among the adverse outcomes caused by such accumulation include disruption, loss of radiation, and degradation of energy confinement. Meanwhile, literature indicates that tungsten accumulation could be suppressed by controlling the neoclassical transport, inward pinch of high-Z impurities (PHZ), and radial electric field (Er). Furthermore, these three variables were associated with NBI. Thus, this study focused on the potential of NBI in manipulating tungsten behavior in the core of an EAST type-I ELMy H-mode plasma, a mode that led to strong impurity accumulation in EAST. By mastering the technique to avoid tungsten accumulation, the EAST will be able to perform more optimally.
[the_sdg_impact] => As the first Tokamak with superconducting toroidal and poloidal magnets, the EAST is valuable for nuclear fusion and plasma research. Thus, its performance stability and consistency are a top priority. By exploring effective methods to minimize tungsten accumulation in the EAST, this research showcased efforts that aligned with the targets of UNSDG 9: Industry, Innovation & Infrastructure.

[video] =>
[the_novelty] => In this study, we design a new lattice of the Shanghai Synchrotron Radiation Facility upgrade (SSRF-U), a low-emittance photon source designed with an emittance of 53.2 pm·rad (N-IBS), using 20 seven-bend achromat cells. This small emittance and high electron density will inevitably lead to non-negligible intra-beam scattering (IBS) and Touschek scattering. Therefore, to weaken the effect of IBS and Touschek scattering, emittance growth and beam lifetime in the SSRF-U storage ring were studied by particle simulation within a series of different machine configurations. After considering almost all the methods, the best configuration was obtained, contributing to the upgrade plan of the SSRF storage ring. The method proposed in this paper would serve as an important reference for transforming other light sources or designing and constructing new light sources.
[the_background] => The high-performance SSRF has contributed to significant scientific findings related to various research fields, including biomedicine, material science, environmental science, physics, and chemistry. Meanwhile, there is an increasing demand for synchrotron light sources with reduced beam emittance approaching or reaching X-ray diffraction limits. However, the properties (e.g., beam lifetime and brightness) of such light sources are bound to be degraded by IBS and Touschek scattering. While designing a new lattice of the storage ring, reaching soft-X ray diffraction limit, to upgrade the SSRF, this study has also run extensive simulations to overcome the adverse effects of IBS and Touschek scattering. By identifying the optimal parameters for yielding a beam with lower emittance and higher brightness. The SSRF-U would become one of the state-of-the-art research assets to facilitate scientists making exceptional scientific contributions.
[the_sdg_impact] => The SSRF is well-known as a necessary light source facility that contributes to multiple subjects of studies. Despite that, continuous upgrading and improving SSRF are essential to enhance its beam properties and performance to keep up with the rapid pace of scientific research. The candidate lattice of the storage ring for SSRF-U, reaching soft-X ray diffraction limit and Intra-beam scattering optimization, contribute to the upgrade plan of the SSRF storage ring. Hence, this study is well-aligned with the targets of UNSDG 9: Industries, Innovation & Infrastructure.

[the_novelty] => This study proposed a novel immunotherapy strategy to treat various solid tumors more effectively and safely. The proposed chimeric antigen receptor (CAR)-T therapy using natural killer (NK) cells, when used to target tumor-associated antigen (TAA), caused lesser damage to healthy tissues. The neoexpressed TAA of interest is known as human leukocyte antigen G (HLA-G). Results indicated that by targeting HLA-G, the proposed CAR-NK successfully triggers the cytotoxic killing response of the immune system when it recognizes the tumor cells. Moreover, the efficacy of the treatment is seen to increase when the tumors are pre-exposed to low-dose chemotherapy. Overall, the study showed promising results under laboratory conditions. However, further studies are suggested to validate the combined effects of chemotherapy and HLA-G CAR-NK cells and expand the application in clinical settings.
[the_background] => Among the greatest challenges when treating solid tumors is the immunosuppressive tumor microenvironment (TME), leading to low and ineffective immune responses. Although past attempts using CAR-T to target these immunosuppressive TME showed positive results, severe damages to non-tumor cells have been reported. Moreover, monotherapy of CAR through the conventional techniques have also presented limitation, thus, suggesting a need to explore combined therapies to increase the antitumor capability of the treatment. This study aims to improve the antitumor efficacy of CAR-T treatment strategy by identifying an accurate target and exploring potential combined strategy by understanding the synergistic mechanisms involved.
[the_sdg_impact] => In recent years, precision medicine has become a highly sort after area of cancer research. The concept primarily revolves around targeted care through individualized treatment approaches. One such treatment is immunotherapy, sometimes known as biological therapy, which uses the body’s natural defense mechanism to fight cancer. According to a statistic shared by John Hopkins, to date, approximately 15-20% of patients have achieved long-lasting results with the treatment. With most existing treatments still being in the trial phase or displaying a certain amount of limitation, clearly, there is room for further improvement. This study, therefore, could potentially serve as a significant breakthrough in the field by increasing cancer cell target precision and treatment efficacy. Such outcome also aligns with the visions of UN SDG 3: Good health and well-being in reducing the mortality rate of non-communicable diseases, like cancer, through prevention and treatment.

[the_novelty] => This study proved that disrupting tyrosine-211 phosphorylation of proliferating cell nuclear antigen (pY211-PCNA) is crucial to stopping the spread of breast cancer. By blocking the phosphorylation of the key DNA replication coordinator (PCNA), the replication mechanism collapses. Thus, a series of inflammatory responses outside the tumor cell is triggered. Such immune response is mediated by natural killer (NK) cells which then signal the stop of tumor from spreading any further. These findings provided valuable insights on the previously unclear tumor-promoting signaling pathway. Potentially, such understanding would benefit the development of effective anti-cancer immunotherapy strategies.
[the_background] => Cancer cells have a strong replication stress-coping capability, enabling them to divide and grow uncontrollably compared to normal cells. Such characteristic is a result of the ability of these cancer cells to promote DNA damages repair. With that said, much of the underlying signaling mechanisms are still poorly understood. Therefore, this study aims to investigate the mechanisms involved in the regulation of DNA replication within breast cancer cells and understand the impacts on tumor progression.
[the_sdg_impact] => According to the statistics provided by WHO, an estimated 2.3 million women were diagnosed with breast cancer, with close to 700 000 deaths reported globally in 2020 alone. Existing treatment often consists of a combination of surgical removal, radiation therapy, and medication to prevent further spreading of the tumor. Hence, to reduce the mortality rate among women with breast cancer, research should explore effective tumor biomarkers and target pathways. By providing significant insights on how cell proliferation mechanisms can be reprogrammed to inhibit tumor growth, this study serves as a good reference in developing future immunotherapy.

[video] =>
[the_novelty] => This study proved that non-small cell lung cancer (NSCLC) patients who smoke are less likely to respond to existing epidermal growth factor receptors tyrosine kinase inhibitor (EGFR TKI) treatment. The findings suggested that by including metformin, a drug for diabetes mellitus, the enzymatic activation of liver kinase B1 – AMP-activated protein kinase (LKB1-AMPK) will produce better response to EGFR TKI and clinical outcomes. This is primarily due to the effectiveness of the combination in improving treatment sensitivity and reducing tumor growth, as shown in both in vitro and in vivo attempts for patients with wild-type LKB1. Thus, confirming the proposed addition of AMPK activator metformin can overcome the treatment resistance experienced by a majority of wild-type EGFR NSCLC patients who smoke. Essentially, such insights are useful to design new therapeutic strategies for NSCLC patients who are least receptive to existing treatments.
[the_background] => The EGFR is among the key targets when treating NSCLC. Hence, EGFR TKI has been widely used as part of the initial treatment strategies. However, the clinical outcomes tend to vary in terms of effectiveness for NSCLC patients with wild-type EGFR. Increasingly, reports have associated smoking consequences with the development of lung cancer and the reduction of EGFR TKI treatment responsiveness in NSCLC patients. Therefore, this study aims to understand the EGFR TKI resistance mechanisms in NSCLC patients who smoke. The findings would potentially be used to explore an effective treatment strategy against NSCLC, especially for patients with wild-type EGFR.
[the_sdg_impact] => Approximately 80% to 85% of lung cancers are recognized as non-small cell lung cancer (NSCLC). According to the National Cancer Institute of the U.S., smoking cigarettes, pipes, or cigars are major risk factors leading to the development of the disease. By identifying the biological mechanisms that associate cigarette extracts with NSCLC treatment resistance, this study expands the possibility of increasing the effectiveness of the existing treatment. Ultimately, the proposed combination of metformin with EGFR TKI would serve as a new therapeutic strategy to promote treatment response and reduce the mortality rate of patients with NSCLC.

[the_novelty] => This in-situ study reported the crystal structure of EcCdnD, a CD-NTase from Enterobacter cloacae that produces cyclic AMP-AMP-GMP in apo and substrate-bound forms. Besides having two ATP binding sites, its overall structure was different from that of other CD-NTase. Furthermore, the relationships between its structure and activities were discussed in detail. Findings showed that EcCdnD is active when it binds to ATP or a combination of ATP and GTP. Moreover, Mg2+ is the cofactor that contributes the most to the activity of EcCdnD. Based on the results, a catalytic pathway for the CTN-producing EcCdnD is proposed. Further research is needed to confirm the exact catalytic pathway.
[the_background] => Cyclic nucleotides are intracellular second messengers that regulate cell function by controlling the activity of protein kinases. Some cyclic dinucleotides (CDNs), which play crucial roles in the immune system, are synthesized by mammalian cyclic GMP-AMP synthase (cGAS) and its homolog dinucleotide cyclase in Vibrio cholerae (VcDncV). Among the recently discovered cGAS/DncV-like nucleotidyltransferases (CD-NTases), only two cyclic-trinucleotides (CTN)-producing Type I CD-NTases had undergone analysis of crystal structure. Therefore, this study was conducted to complement the knowledge gap by determining the structure and activity of EcCdnD in apo-form and when bounded to various substrates and mutants. Along with the possible catalytic mechanisms that produce CTNs, the output of this research serves as a robust reference for future studies of CTN-producing CD-NTases.
[the_sdg_impact] => Cyclic nucleotide signaling is an essential cellular central relay system that translates primary signals (e.g., hormonal stimuli or changes in the cellular environment) to a cellular response. Since the structure of bacterial CD-NTases is similar to that of mammalian cGAS and oligoadenylate synthetase (OAS), a better understanding of the former’s properties and catalytic pathway would help advance biomedical sciences. In extension, the biochemical and biophysical studies of EcCdnD in this research potentially contribute to the realization of UNSDG 3: Good Health & Well-Being by expanding the knowledge base of cyclic nucleotides.

[the_novelty] => Is there an efficient way to simplify the workflows of lipidomic analysis and studies of lipid characteristics? This research develops the first web-based platform, LipidSig, which allows users to conduct in-depth and comprehensive lipidomic analysis efficiently. Users can upload up to four tables of different analysis sections. Based on the data uploaded, LipidSig can carry out five functions (i.e. Profiling, Differential Expression, Correlation, Network, and Machine Learning) to analyze lipidomic change thoroughly. In addition, LipidSig has a unique feature that enables the conversion between lipid species and characteristics according to a user-defined characteristics table. As a web-based tool, there is great potential for LipidSig to be improved and optimized continuously to meet the needs of users.
[the_background] => Different from general metabolites, lipids could exert distinct biological functions not only as an individual but also as a group defined by a variety of lipid characteristics (e.g., lipid classes, shapes, double bonds, chain lengths, and hydroxyl groups). To date, one of the bottlenecks faced by lipidomic studies is the lack of analysis tools to efficiently analyze both lipid species and lipid characteristics. Despite the readiness of several tools for analysis of lipid characteristics, some of them impose strict formatting requirements on lipid names, while some can hardly conduct characteristics analyses beyond lipid class, chain length, and double bonds. Hence, this study develops the first web-based tool, LipidSig, which shows high efficiency and flexibility in analyzing streamlined data mining of lipidomic datasets. Being a completely free tool with advanced features, LipidSig provides researchers in lipidomics to further develop and enhance their research.
[the_sdg_impact] => Lipids play multiple crucial roles ranging from storing energy to forming signaling molecules. Thus, a comprehensive knowledge base for the diversity and composition of lipids will contribute to more significant discoveries of lipids’ biological functions. The potential of LipidSig in the development of lipidomics has been proven by its features to bridge the existing gaps in the lipid-specific analysis. With that, this study serves as an epitome to enhance physiological and pathological research as well as encourage further scientific discoveries as envisioned in UNSDG9: Industry, Innovation & Infrastructure.

[graphic_abstract] =>
[figures] =>
[video] =>
[the_novelty] => Why is the battle against COVID-19 far from over? The coronavirus (SARS-CoV-2) is known to have a complex array of messenger RNA (mRNA) and share molecular similarities with human proteins. Thus, upon infection, extreme autoimmune and inflammatory reactions could be triggered. Based on a systematic review of existing case reports, this study summarized a list of potential triggers of autoimmune and rheumatic diseases following the COVID-19 infection. Among the rare but significant incidences associated are autoimmune cytopenia, cutaneous vasculitis, encephalitis, and Guillain-Barre syndrome. However, it should be noted that most of the literature analyzed was of short-term case reports or case series. For a more definitive conclusion, the study suggests future research to consider establishing a long-term follow-up mechanism.
[the_background] => At present, the only available method to defend ourselves from COVID-19 is through vaccination. However, there are rising concerns and hesitancy among vaccine recipients due to its potential to trigger autoimmune and rheumatic complications. Moreover, the rapidly piling up literature makes it even harder for information seekers to acquire reliable and recent resources. Therefore, this study aimed to compile existing evidence from peer-reviewed sources such as PubMed and EMBASE to verify and produce a list of autoimmune and rheumatic diseases potentially associated with COVID-19 infection. Such a thorough overview would benefit vaccine developers in terms of vaccine design and post-marketing surveillance.
[the_sdg_impact] => While the UN’s 3rd SDG, Good health and well-being, focused on increasing life expectancy and reducing mortality rates of some common diseases, more efforts are required to manage a wide range of other existing and emerging health issues. The 2020 COVID-19 pandemic has caused a global health crisis where the preparedness of healthcare systems of developed and under-developed nations is equally challenged to manage a threat of such scale. Hence, this study would serve as a good reference for healthcare authorities when handling the global immunization efforts against COVID-19.

[figures] =>
[video] =>
[the_novelty] => This study provided evidence that combined exposure to heavy metals (Pb with As, Cd, and Hg) during pregnancy and infancy periods could cause children to develop asthma in later stages. The findings primarily focused on understanding the effects of such exposure on the lung development mechanism and to recognize the sensitive time windows which lead to the risk of asthma development in children. Contrary to most occupational exposure to high levels of heavy metal exposure, even low levels of these components when inhaled during and post-pregnancy by the mother and infant could trigger the disease. The specific sensitive time windows identified are during gestational weeks 1 to 14 and 21 to 40, and 1 to 3 weeks after birth. These results serve as a warning to pregnant women and mothers to avoid getting themselves and their newborns exposed to serious outdoor air pollution.
[the_background] => Asthma is a common allergic respiratory disease among children and adults. Much of the causes of this disease are either genetic or environmental. Past studies have linked exposure to air pollution with numerous respiratory diseases development. However, most of these studies evaluate the effects of high levels of heavy metals exposure under working environment. To date, there are limited evidence on the effects of low-level exposures of such poor air quality on children with asthma. Therefore, this study focused on assessing the effects of inhaling traces of heavy metals during and post-pregnancy to determine accurate sensitive time windows.
[the_sdg_impact] => Globally, more than 300 million people suffer from asthma. According to the World Health Organization (WHO), the number of patients with asthma is expected to increase by 100 million by 2025. On the other hand, it is undeniable that the air quality has deteriorated over the years due to pollution and high levels of fine particulate matter in the air continue to impose greater health concerns. Thus, the study findings are essential for pregnant women and new mothers to take necessary precaution to avoid exposure to serious air pollution. Moreover, healthcare practitioners could use the findings are a reference to advise the groups at risk to take appropriate measures to ensure the healthy development of their children (SDG 3: Good health and well-being).

[the_novelty] => This research evaluated the risk of prolonged hospital stay as a result of high blood sugar levels recorded before non-critical surgeries regardless of patient diabetic status. A large retrospective cohort study was conducted by analyzing patients' medical records of appendectomy and laparoscopic cholecystectomy at China Medical University Hospital (CMUH), Taiwan, between 2003 and 2016. The findings proved that patients with higher preoperative blood glucose (POBG) level undergoing these standard procedures are more likely to have an extended hospitalization than those with lower POBG levels. To be precise, appendectomy patients with POBG levels of ≥123 mg/dL are 19% more likely to stay beyond 3 days in the hospital, while laparoscopic cholecystectomy patients with POBG levels of ≥128 mg/dL had a 17% higher risk. Thus, it was concluded that the optimal POBG level with reduced risks might be lower than the current standards for common surgeries. Such insight could improve existing clinical practice guidelines for patients undergoing surgery to ensure an effective recovery experience.
[the_background] => There is an ongoing debate on whether routine blood sugar levels before surgery are necessary for healthy or asymptomatic adults. To date, there are no fixed guidelines available for such assessment, especially for those undergoing elective non-critical surgical procedures. However, increasing evidence has shown that high preoperative blood sugar levels do harm surgical patients. Hence, this research aimed to assess the effect of POBG level on hospital length of stay in patients undergoing appendectomy or laparoscopic cholecystectomy, both of which are highly standardized and regulated non-critical procedures. The findings would serve as a potential basis for exploring the role of POBG levels in determining factors affecting patient recovery.
[the_sdg_impact] => The Lancet Commission on Global Surgery (LCoGS) 2030 report, supported by WHO, aims to strengthen global surgical ecosystems, especially by focusing on the integration of emergency and essential surgical care within universal health coverage (UHC) plans (Global Surgery 2030). From a broader perspective, these efforts are directed to enable economic growth, UHC, and the achievement of UN SDGs. When looked at closely, the findings of this research could potentially play an important role in improving under-addressed surgical issues and providing quality healthcare services for patients (SDG 3: Good health and well-being).

[the_novelty] => This study includes different proteomics, genomics, and imaging experiments conducted on in-vitro (cellular) and in-vivo (animal) models. The findings established the role of interleukin 17 receptor B (IL-17RB) in tumorigenesis and metastasis of pancreatic cancer via a distinct pathway. It revealed that the phosphorylation of tyrosine-447 (Y447) is highy important for IL-17 induced signaling IL-17RB, which associates with clinically aggressive pancreatic tumors. Upon discovering the importance of mixed-lineage kinase 4 (MLK4) in IL-17RB signal transduction, it was found that two identical subunits of IL-17RB need to form a complex, a homodimerize, to be able to recruit MLK4. Moreover, phosphorylation of IL-17RB at Y447 proved vital for the recruitment of other important proteins for its downstream signaling pathway. The significance of these findings was further validated when treatment with a loop peptide dampened the phosphorylation of Y447 and reduced metastasis progression in pancreatic cancer. By understanding the signaling mechanism of IL-17RB which triggers tumorigenesis, potential treatment strategies for pancreatic tumors can be further explored.
[the_background] => Unlike other IL-17 receptors, the role and physiological nuances of IL-17RB in inflammation or pancreatic cancer remain unclear in past studies. Similarly, the binding of ligand IL-17 to the homodimer or heterodimer complex of the receptor was unknown. This study has not just answered these questions but also demonstrated the signal transduction and mediators involved in binding IL-17 to IL-17RB to elicit its tumorigenicity. The findings proved that inhibiting IL-17RB activation diminishes tumorigenesis and metastasis, reducing pancreatic tumor development, especially in-vivo. One of the limitations of the study is the inability to assess the conformational change of the receptor to recruit related mediators, which opens avenue for future studies to validate this using cryo-electron microscopy. In addition, modification on the loop peptide to target critical steps involved in IL-17RB oncogenic signaling will potentially reveal new chemical entities as candidates for treatment in pancreatic cancer.
[the_sdg_impact] => The incidence of pancreatic cancer has been increasing by the year. In 2020, close to 500,000 new pancreatic cancer incidences were recorded globally, and an almost equal number of people died of the disease. Thus, making it the 7th most common cause of cancer-related death (WHO, 2020). It is worrying that high mortality and incidence of the malignancy are correlated to high prevalence of other comorbidities, implying compromised quality of life. Hence, it is highly crucial to invest in discovering more effective treatments for this cancer to support United Nations Sustainable Development Goal (UNSDG)3: Good health and well-being, to empower the health of the global community to improve the quality of human capital.

[the_novelty] => This study highlights the unique formation of medusa tentacles in jellyfish, C. pacificum, and the mechanisms involved. The formation of these tentacles followed a simple branching rule observed only in this species combined with a specific cell signalling, mitogen-activated protein kinase kinase (MEK) signalling. Findings indicated that tentacles branch through repeated addition of new branches to the proximal region of the main tentacle during the elongation process. Noticeably, the use of a simple rule to create complex branched structures is also found in branching morphogenesis of other animals such as Drosophila and mammals. In addition, receptor tyrosine kinase signalling could be required for the C. pacificum tentacle branch formation just like organ branch formation in Drosophila and mammals. Results also showed that changing functions of the branches from sticking to surfaces to hunting prey during the development process. As a whole, such an in-depth understanding of the unique branching features of a least studied species like the jellyfish could potentially benefit future animal development studies.
[the_background] => Branched structures are formed in certain organs of various species to carry out a range of functions. Previous literature showed the formation and functions in fruit flies’ trachea and mammalian organs such as lungs. Generally, branched tentacles are rare in jellyfishes except for jellyfishes in the Cladonematidae family. It is currently unclear how different or conserved mechanisms are involved in forming branched organs across the animal kingdom, as most available literature focused primarily on fruit flies and mammals. Therefore, this study aims to provide descriptive and functional information on the branching pattern of branched tentacles in jellyfishes.

[the_novelty] => What is the molecular mechanism underlying the potential of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) in treating depression and reducing neuron inflammation? Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found to have antidepressant, anti-inflammatory, and neuroprotective effects. For the first time, this study identified lipoxygenase (LOX) and cytochrome P450 (CYP450) EPA/DHA metabolites as the mediators of the protective effect of these ω-3 PUFAs. Lipid mediators hydroxyeicosapentaenoic acid (HEPE), hydroxydocosahexaenoic acid (HDHA), epoxyeicosatetraenoic acid (EpETE), and epoxydocosapentaenoic acid (EpDPA) were detected in the human brain after EPA and DHA were metabolized. Therefore, co-treatment with soluble epoxide hydroxylase (sEH) enzyme inhibitor, TPPU, was able to amplify the protective effects. Consistent results were obtained from both in vitro and clinical studies. As an extension, the research will involve a larger cohort of depressed patients and other forms of ω-3 PUFAs metabolites, such as endocannabinoids, in the future.
[the_background] => A correlation between severe depression and inflammation was reported in past studies. However, even though EPA and DHA were proven to exhibit anti-inflammatory and antidepressant properties, its mechanism remained obscure. Therefore, an effective anti-inflammatory treatment strategy is crucial. Meanwhile, there was no evidence from past literature that ω-3 lipid metabolites were produced in the human brain. For the first time, this study demonstrated that EPA and DHA were broken down in neurons into lipid mediators, which improved depressive symptoms. These findings are crucial in developing an effective therapeutic strategy for depression and other inflammation-associated brain disorders.
[the_sdg_impact] => Approximately 280 million people worldwide suffer from depression, the most common mental disorder leading to suicide. More importantly, to date, there is no effective treatment that is safe for daily use. Hence, by uncovering the mechanism in which EPA and DHA exhibit anti-inflammatory and antidepressant properties, an effective therapeutic supplement can be developed to curb depression with minimal adverse effects. In short, the output of this study contributes significantly to the development of medicines for inflammation-associated brain disorders, fulfilling UNSDG 3: Good Health & Well-Being.

[the_novelty] => The study identified an interaction between epidermal growth factor receptor (EGFR) and brain acid soluble protein-1 (BASP1) that contributes to EGFR signaling in brain metastatic lung cancer. The results demonstrated that BASP1 is associated with poorer outcomes, enhances cellular proliferation, and colony formation in lung cancer. The BASP1 role in tumorigenicity was proven via in-vitro and in-vivo by investigating the migration and metastatic potential of the protein of interest in this tumor. One of the most important discoveries of this research is the interaction between BASP1 and EGFR that enhances EGFR signaling, which activates a positive feedback loop by recruitment of BASP1 to lipid rafts. This finding enabled the researchers to identify the harmful impact of BASP1 in reducing drug sensitivity in lung cancer treatment. The light shed on the role of BASP1 via these discoveries encouraged the scientists to identify potential synergistic treatment options for lung cancer with arsenic trioxide and tyrosine kinase inhibitors (TKI) combination. Future studies exploring the functions of BASP1 based on its localization in different tumors can further reveal the universal role of the protein in various malignancies.
[the_background] => TKIs targeting EGFR are among the first-line treatment options for metastatic non-small cell lung cancer (NSCLC). However, the development of resistance over time eventually renders the treatment ineffective. Hence, it becomes crucial to discover therapeutic strategies that inhibit alternative tumor survival signaling pathways that maintain persistent oncogenic EGFR signaling. This study explored the interaction between BASP1 and EGFR, especially in lung cancer with brain metastasis, and investigated potential combination treatment that targets the BASP1-EGFR axis to overcome TKIs resistance. Contrary to the known function of BASP1 as a tumor suppressor, the study revealed that BASP1 is highly expressed and associated with poorer outcomes in brain metastasis. The findings highlighted a promising outcome through blockage of the positive feedback loop between EGFR and BASP1. Thus, paving the way for future research on potential treatment strategies using EGFR TKIs for lung cancer.
[the_sdg_impact] => According to WHO, lung cancer is the most common cause of cancer-related deaths in 2020, accounting for 1.8 million deaths with 2.21 million new cases recorded. The death to new cases ratio is the highest for lung cancer, urging the discovery of an effective therapeutic regimen for the disease, especially in brain metastatic lung cancer. This study focused on identifying the molecular basis behind therapeutic failure and poor prognosis in lung cancer. Ultimately, the findings would contribute to developing possible resistant-free and more effective treatment for lung cancer. Such a study is necessary to improve clinical management of the disease and potentially reduce mortality rates (SDG 3: Good health and well-being).

[the_novelty] => This study further affirms that exposures to fine particulate matter (PM2.5) during late pregnancy and early infancy increase the risk of allergic rhinitis (AR) development in a later stage. Despite the past association of PM2.5 exposure with the cause of AR, this is the first birth cohort study to identify the vulnerable time window, which is from gestation to early childhood. Potentially, such a scenario is triggered by the exposure of PM2.5 during critical stages of the sino-nasal development during late pregnancy and early infancy stages. The results would serve as a reference to determine the appropriate methods to decrease adverse effects of the condition. That said, further investigation on PM2.5 association with AR development is needed to verify the vulnerable time window suggested by this study.
[the_background] => Allergic rhinitis (AR), also called hay fever, is a series of inflammatory reactions triggered by environmental or indoor allergens, such as pollen, dust, skin flake, and mold. While AR is not a life-threatening disease, the array of symptoms associated with the condition is known to cause significant inconvenience to those diagnosed with it. Past studies have linked fine particulate matter (PM2.5) exposure with several allergic respiratory diseases, yet its role in AR development remains unclear. Moreover, there are conflicts between findings in Asian and Western countries regarding long-term PM2.5 exposure and AR incidence. Therefore, this study combined a large population-based birth cohort study with satellite data to identify the PM2.5 exposure period and evaluate its impact on the onset of AR.
[the_sdg_impact] => An article in Medscape highlighted that allergic rhinitis incidence had increased worldwide. Approximately 40% of children are affected, of which the highest prevalence of severe AR is found in Africa and Latin America. Similarly, the air quality has deteriorated over the years due to pollution and high levels of fine particulate matter in the air continue to impose greater health concerns. Thus, the study findings are essential to healthcare practitioners to advise expectant mothers and mothers of newborns to take appropriate measures to ensure the healthy development of their children (SDG 3: Good health and well-being).

[the_novelty] => This study constructed a windowless gas stripping room with two differential pipes in a neutral particle analyzer (NPA) with parallel electric and magnetic fields (E//B), a diagnosis device in Tokamak (toroidal device used in nuclear fusion research for magnetic confinement plasmas). As a result, the new design eliminated the replacement of stripping foils and eased the operation maintenance process. Moreover, multiple simulations, such as ANSYS Fluent, MolFlow+, and GEANT4, were applied to evaluate the design performance in terms of gas pressure distribution and stripping efficiency. It was identified that the optimum pressure for maximum global efficiency is 240 Pa. In the long run, the findings could improve the NPA diagnosis for the nuclear fusion study.
[the_background] => As a diagnosis device in the Tokamak, an NPA measures the charge exchange neutral particles escaping from plasma. Its functions include studying the energy distribution of fast ions and the isotopic ratio of the plasma. An NPA consists of a stripping unit that re-ionizes the neutral particles escaping from the Tokamak through charge exchange reactions. The stripping unit comprises stripping material in the form of either stripping foil or stripping gas. This study designs and simulates a windowless gas stripping room with two differential pipes in an E//B NPA to improve the device’s performance and maintenance, especially in terms of optimum pressure for maximum global efficiency. The simulation results would serve as a reliable reference for future practical applications.
[the_sdg_impact] => At present, power plants generate electricity and energy through fossil fuels, nuclear fission, or renewable energy sources. A Tokamak is an experimental machine designed to harness the energy of nuclear fusion, potentially serving as an alternative to future energy generation. To turn such experimental design into reality, it is crucial for researchers to constantly explore new ways to improve and maintain the performance of the Tokamak facility. Therefore, the findings of this study contribute to the efforts of the understanding and the betterment of the device. It would eventually be beneficial to advance the future of energy production.

[the_novelty] => This study proposed an improvement to the existing special nuclear materials (SNMs) detection models by combining two spectroscopy techniques, i.e., scattering nuclear resonance fluorescence (sNRF) and transmission-NRF-based computed tomography (tNRF-CT). The combination enabled the proposed detector to identify isotopic composition and spatial distribution of 235,238U when concealed in a 3-cm diameter iron rod. The outcome indicated a shortened interrogation time by one order of magnitude, making it a more rapid and sensitive option than the current tNRF-CT approach. Thus, the successful attempt of the proposed model in lowering the missed-detection rate within a realistic interrogation time would be of great value to upgrade national and global security systems.
[the_background] => The integrity of global security has constantly been threatened due to the potential smuggling of special nuclear materials (SNMs) across borders and through ports of entry. As a matter of fact, the Incident Trafficking Database developed by the International Atomic EnergyAgency has reported several hundred incidents of illicit trafficking and malicious use of certain nuclear and radioactive materials. Existing passive detection systems are ineffective when the interrogated SNMs are shielded, considering the low spontaneous radiation intensity and energy emitted in most cases. Therefore, this study proposed an active detection technique that uses external radiation sources to develop a more accurate, effective, and practical approach to non-destructively inspect SNMs, especially uranium.
[the_sdg_impact] => International organizations such as the Nuclear Threat Initiative (NTI) in the U.S. and the United Nations Office for Disarmament Affairs (UNODA) are constantly trying to strengthen global security against threats, one of which is nuclear terrorism. Hazardous nuclear materials falling into the wrong hands could lead to catastrophic events ranging from poisoning and radiation burns to nuclear attacks. To prevent such incidents, security systems need to be constantly upgraded, especially in terms of material inspections at borders, ports, and checkpoints. This study proposed a feasible technique to improve the non-destructive inspection capability of special nuclear material (SNM) through an innovative combination of imaging technologies. The outcome indicates that integration of such techniques could be beneficial to strengthening national and international security systems against nuclear smuggling, in extension, maintaining world peace.

[the_novelty] => This study has found that nitrogen doping/infusion could increase the intrinsic quality factor (Q0) of the 650 MHz cavities used in a circular electron-positron collider (CEPC). Adopting a buffered chemical polishing (BCP) surface baseline prior to the nitrogen infusion of a 650 MHz 2-cell cavity yielded a Q0 of 6 × 1010 at 22 MV/m in the vertical test and a maximum gradient of 25 MV/m. The Q0 exceeded the specification of CEPC, i.e., 4 × 1010 at 22 MV/m. By optimizing nitrogen infusion and BCP, the performance of the 650 MHz cavity can be further enhanced.
[the_background] => The CEPC is a high-energy collider of the Higgs factory. Constructed 100 m underground, two hundred and forty 650 MHz 2-cell cavities and ninety-six 1.3 GHz 9-cell cavities exist in the collider and the booster. The 650 MHz 2-cell cavities economically support the cryogenics system by operating in continuous wave mode with high-quality factor (Q). Electro-polishing (EP) is commonly adopted for the nitrogen doping/infusion of the cavities abroad. However, in China, buffered chemical polishing (BCP) is relatively more feasible to be adopted instead. This study conducted a nitrogen infusion and doping study on 650 MHz cavities BCP treated to confirm its feasibility. Results showed that the Q0 achieved exceeded the specifications of CEPC. Therefore, nitrogen doping/infusion of cavities BCP treated is effective and easy to promote.
[the_sdg_impact] => Superconducting cavities with high Q and gradient are advocated by many applications, such as wastewater and sludge treatment, safety, flue gas treatment, nuclear waste destruction, etc. The highly effective BCP surface baseline reported in this study offers an alternative option to researchers seeking a feasible surface baseline for nitrogen doping/infusion besides EP. Hence, this study aligns with the objectives of UNSDG 9: Industry, Innovation & Infrastructure, to enhance scientific research.

[the_novelty] => This study showed that the connections between fin rays and distal radials influence patterns exhibited by zebrafish's pectoral fin rays along the antero-posterior (AP) axis. Through detailed morphological observation, it was noted that the formation of the pattern relied on the developmental genes for AP patterning in the limb/fin bud. Such developmental mechanisms were similar to those of the distal element of the limb skeleton. The reported topological relationships and development processes serve as valuable literature to facilitate studies related to the skeletal patterns of fish.
[the_background] => Fin rays are rod-like support of the fin membrane. They are often observed in various fish and are attached to the distal radials to exhibit patterns. However, there were limited reports on pattern formation. Furthermore, the topological relationships, as well as the developmental process between the fin rays and distal radials, were ambiguous. This study intended to investigate the topological relationships, which are the structural organizations, and developmental mechanisms in forming patterns of fin rays along the antero-posterior axis. The findings also showed how different parts of zebrafish are closely related in the development to form important structures for supporting daily activities.
[the_sdg_impact] => Morphological studies contribute to a range of implications, be it to deepen the understanding of the biological evolution of organisms or design development of infrastructure. The techniques used in this study do not just provide deeper insights into the structures of zebrafish's fin ray and distal radials; instead, the findings could potentially be useful to marine researchers interested in exploring similar structures of other aquatic creatures. Directly and indirectly, such understanding could provide better solutions in sustaining marine resources (UN SDG 14: Life below water). Moreover, understanding fin design and development is crucial in diversifying hydrodynamics-related experiments and features needed to build resilient infrastructure and foster innovation (UN SDG 9: Industry, innovation, and infrastructure).

[the_novelty] => The study found that the general structural characteristics between Stephanella hina and other freshwater bryozoans (moss animals) were not too different. However, Stephanella hina did possess distinct cladistic traits, separating it from the rest of the freshwater bryozoans. The most distinctive feature of Stephanella hina, according to the in-vivo analysis, is their lophophore structure and neuromuscular intricacies, differing from other Phylactolaemate bryozoans. However, it remains unclear if these differences are biologically classified as non-ancestral (apomorphic) or ancestrally shared (plesiomorphic), suggesting a potential future expansion.
[the_background] => This research describes features that differentiate Stephanella hina from other Phylactolaemate bryozoans. Bryozoa are essentially a category or phylum comprising aquatic colonies that are especially diverse in marine areas. Phylactolaemata is a division within Bryozoa that describes colonies native to freshwater, such as Stephanella hina. There has not been much detailed research conducted on Stephanella hina to properly understand the structural characteristics of this species. Therefore this study performed a thorough in-vivo analysis to fulfill the research gap. This study suggests an analysis of the family Lophopodidae, the early branch in Phylactolaemate bryozoans, to truly understand if the differences found were ancestral (plesiomorphic) or non-ancestral (apomorphic).
[the_sdg_impact] => A quick observation of Stephanella hina distribution through NatureServe Explorer (see: https://explorer.natureserve.org/Taxon/ELEMENT_GLOBAL.2.119240/Stephanella_hina) will reveal that much about the species is a mystery aside from generic taxonomic information. Since the Phylactolaemate bryozoans are the early branch of the phylum Bryozoa, describing and understanding the structural characteristics of this group, as such, findings from this research would also contribute to increased scientific knowledge per Sustainable Developmental Goal 14.A to further advance marine health. Understanding the differences between Stephanella hina and other Phylactolaemate bryozoans allows effective enactment of SDG 14.5 to conserve at least 10 percent of coastal and marine areas based on reliable scientific information through means that complement the differences. Understanding the origin of these differences is crucial to determine if the differences are plesiomorphic or apomorphic to further enhance scientific and conservation efforts.

[the_novelty] => The CRISPR/Cas is a tool known for its targeted gene integration, yet there is room for overall efficiency enhancement. This study demonstrated that targeted gene integration events could be induced more efficiently using donor plasmids with longer homology arms than those with shorter homology arms. Besides that, linearization of circular donor plasmids and utilization of suitable bait sequences also increased the efficiency. The targeted gene integration events were attempted using CRISPR/Cas system and donor plasmids with homologous sequences in medaka (Oryzias latipes). The results implied that its efficiency was possible to be further increased via suitable techniques.
[the_background] => The CRISPR/Cas system is a powerful genome-editing tool. Despite being well-known for its potential, the number of reports on targeted gene integration using the CRISPR/Cas system was scarce. This implied the availability of room for optimization on the performance of this system. Therefore, via in vivo and in silico experiments, this study attempted to enhance the efficiency of targeted gene integration events in medaka. Such effort paves a path for related future research to be carried out more effectively using similar methods in other fish species.
[the_sdg_impact] => Gene-editing technology is capable of re-designing the genome of organisms and plants. Imperfections, such as inherited illness, are possible to be eliminated in the offsprings through this technology. Meanwhile, the techniques to increase the efficiency of the CRISPR/Cas system create higher possibilities to achieve better results in gene editing. By introducing these techniques, the outcome of this study is able to facilitate future studies which adopt the CRISPR/Cas system. Hence, this research is well-aligned with UNSDG 9: Industry, Innovation & Infrastructure by enhancing scientific research.

[the_novelty] => This study disclosed a ligand-receptor relationship that played a significant role in initiating the growth of breast tumors. Human antibody array studies identified hRNase1 as a ligand for EphA4 and that the hRNase 1-mediated EphA4 signaling led to breast cancer development. Moreover, the impact of RNase 1–EphA4 ligand-receptor relationship was consistent with those of hRNase 5–EGFR and hRNase 7–ROS1 in promoting tumor growth. Therefore, further studies focusing on RNase–RTK targeted inhibition would contribute to new therapeutic strategies for various cancers.
[the_background] => Despite the extensive studies on the biochemical properties of hRNase 1, the actual biological function of hRNase 1 has yet to be determined. Meanwhile, the ligand-receptor relationships of hRNase 5–EGFR and hRNase 7–ROS1 were proven to result in tumor growth. Based on those findings, there are reasons to believe that hRNase 1 has similar involvement in cancers. On the other hand, the upregulation of receptor EphA4 in breast cancer stem-like cells (CSCs) indicates the possibility of treating cancer via EphA4 inhibition. Thus, this study investigated the implication of the hRNase 1–EphA4 ligand-receptor relationship in breast cancers. Identifying the critical role of the hRNase 1–EphA4 pair in breast cancer initiation implied that the initiation of other cancers could be due to similar ligand-receptor relationships. Thus, setting a clear study scope for future anti-tumor research.
[the_sdg_impact] => In 2020, 2.3 million women were diagnosed with breast cancer globally. This suggests that there is an urgent need for the development of more promising therapies to treat breast cancer. Along with the findings derived from the studies of hRNase 5–EGFR and of hRNase 7–ROS1 pairs, this study established a firm validation associating RNase–RTK pairs to the root cause of cancers. By identifying the possible pathways for cancers, this study expands the possibility of deriving potentially effective cancer interventions in the near future (UNSDG 3: Good Health & Well-Being).

[video] =>
[the_novelty] => This study identified the potential of tannic acid (a compound found in fruits and plants) as a natural remedy for COVID-19. Results from in vitro experiments showed that tannic acid was able to inhibit the activity of coronavirus SARS-CoV-2’s main protease. Furthermore, tannic acid also prevented the entry of SARS-CoV-2 into cells by inhibiting the human cell surface protease TMPRSS2. By acting as an effective dual inhibitor of the two main proteases involved in coronavirus SARS-CoV-2 infection, the clinical trial of tannic acid in treating COVID-19 is highly anticipated. Meanwhile, since TMPRSS2 is also responsible for prostate cancer progression, future studies can be conducted to examine the potential of tannic acid in suppressing cancer progression through TMRPSS2 inhibition.
[the_background] => From the perspective of biological science, the COVID-19 pandemic can be overcome by deactivating the main protease of coronavirus SARS-CoV-2 and blocking the entry of SARS-CoV-2 into human cells. But, how? In order to prevent the cellular entry of SARS-CoV-2, human cell surface protease TMPRSS2 should be targeted as it was reported to form an ‘entrance’ for such invasion. Various natural compounds from fruits and plants exhibited anti-coronavirus properties. Hence, this study was carried out to determine the potential of tannic acid (a natural compound) in suppressing SARS-CoV-2. The outcome showed that tannic acid was able to deactivate the main protease of coronavirus SARS-CoV-2 and also managed to block the cellular entry of SARS-CoV-2 via inhibition of protease TMPRSS2. The dual action of tannic acid indicated its high potential in battling COVID-19.
[the_sdg_impact] => To date, scientists are still working towards effective remedies to deal with COVID-19 while the global death toll rises. Although numerous vaccination programs have been rolled out globally, the frequent mutation rate to generate viral variants of SARS-CoV-2 has raised the necessity to develop anti-Covid-19 drugs. Therefore, a possible treatment with minimal side-effect is needed as soon as possible. The discovery of tannic acid’s potential as a low-risk yet feasible compound for treating COVID-19 could inspire more magnificent research in a similar direction. Thus, by achieving significant milestones in the research and development of vaccines and medicines for COVID-19, this study contributes to the realization of UNSDG 3: Good Health & Well-being.

[the_novelty] => This novel study revealed the whitening activities of an antioxidant component in blueberries (Pterostilbene) in cells and animals. This was achieved by triggering the melanin cell autophagy mechanism (self-eating) and disabling UV (Ultraviolet)-damaged hormones in keratinocytes through an antioxidant pathway. The findings showed that Pterostilbene activated the Nrf2 antioxidant gene in keratinocytes, stimulating the HO-1 and γ-GCLC antioxidant enzymes. It also increased the autophagy-associated proteins, LC3-II and p62, while simultaneously decreasing the ATG4B protein in melanocytes. Thus, the cells produced their own antioxidants, leading to the inhibition of melanin production. This study can further expand by researching the mechanism involved in Pterostilbene interfering with the melanosome maturation process to better understand its whitening properties.
[the_background] => UV radiation such as UV-A and UV-B rays can penetrate the skin and increase melanin production, causing dark skin spots. Chinese herbal medicine has 13 approved whitening ingredients, which mainly inhibit melanin production and pigmentation. One such ingredient is Resveratrol. Unfortunately, most commercially available sunscreens are not able to resist UV-A rays. However, Pterostilbene is seen as a powerful natural antioxidant that can be applied onto the skin to achieve the whitening effect. Previous studies reported cell autophagy and deactivation of hormones in skin cells aid in Pterostilbene’s whitening effects in various cells and lab animals. However, this is one of the first studies to explain the molecular processes of Pterostilbene’s whitening effects in keratinocytes and melanocytes. In addition, the study uses Zebrafish embryos to prove Pterostilbene’s effectiveness as a whitening component in skin-whitening agents.
[the_sdg_impact] => According to past literature, it was found that the UV radiation in China decreased from 1961 to 1991. However, there seems to be an increase in UV radiation from 1991 to 2012. Similar could be observed with other parts of the world. With increasing UV radiation, more UV-A rays can penetrate the skin and trigger the melanocytes to increase melanin production, leading to dark spot formation on the skin. This can cause frustration and emotional stress in an individual. More research needs to be conducted to identify an effective whitening component to ensure that people can successfully treat these dark skin spots. The aim of this study is aligned with the “Goal 3: Good Health and Well-Being” of the UN’s Sustainable Development Goals. This research could allow the use of Pterostilbene in treating skin diseases caused by UV-A rays.

[the_novelty] => This study is a novel attempt to investigate receptor tyrosine kinase (RTKs) that could potentially contribute to the resistance of anti-programmed cell death protein 1/ programmed death-ligand 1 (anti- PD-1/ PD-L1) therapy in cancer. The outcome showed a significant association between tyrosine receptor kinase protein 3 (TYRO3) and anti-PD-1/ PD-L1 therapy resistance in different tumors. A series of comprehensive research designs, cellular (in-vitro), animal (in-vivo), and retrospective computer (in-silico) analysis on multiple databases, revealed that the high expression and phosphorylation status of TYRO3 correlates to poorer prognosis in anti- PD-1/ PD-L1 treatment and causes resistance. Furthermore, TYRO3 was also found to be suppressing ferroptosis, a nonapoptotic, iron-dependent form of cell death via the AKT/ NFR2 pathway, thus diminishing the sensitivity of cancer cells to anti- PD-1/ PD-L1 treatment. Overall, the study implicates the protein's role as a potential biomarker for patient stratification and therapeutic options.
[the_background] => Immunotherapy that involves blockade of PD-1/ PD-L1 has been clinically gaining interest in cancer treatment due to its anti-tumor potential. Nevertheless, the response rate of PD-1/PD-L1 antagonism as a single therapy in cancer treatment has been relatively low owing to resistance to the therapy and insufficient biomarkers to select patients for treatment. Although there has been emerging evidence of the TAM (TYRO3, AXL, and MerTK) family's role in host immune response, this study proved that TYRO3 participates in eliciting resistance in anti- PD-1/ PD-L1 treatment, and not AXL or MerTK. Following the recent success of RTK inhibitors in cancer treatment, the findings can potentially pave ways to develop therapeutic targets on TYRO3. Considering the structural similarity of TYRO3 to AXL and MerTK, more in-vivo studies should be done in the future to confirm the specificity of the protein's role in contributing to treatment resistance. The study must also be duplicated in different malignancies to understand the protein's universal function and therapeutic efficacy in other tumors.
[the_sdg_impact] => Global oncology spending has steadily increased from USD 56 billion to USD 187 billion from 2011 to 2021, close to a four-fold increase in just a decade (Statista). The economic toll is approximately 19% higher than heart disease, the second leading cause of economic loss following cancer (American Cancer Society). These staggering figures are continuous reminders of the urgent need for targeted therapies and biomarkers in improving the efficacy of cancer treatment. This study builds on the evidence and contributes towards the potential development of RTK inhibitor therapy and biomarkers in different cancers. Thus, it helps realize the United Nation's Sustainable Development Goal, UNSDG 3: Good health and well-being, by contributing to developing therapeutics for a disease that enormously costs the global economy and quality of life.

[the_novelty] => This study emphasizes the role of TET2 in breast cancer development. TET2 is shown to form a complex with transcription factor FOXP1 to mediate the expression of ESR1, GATA3, and FOXA1 genes that are responsible for the development of the mammary gland and response to hormones. Loss of TET2 leads to silenced estrogen receptors (ER) expression, consequently promoting intrinsic resistance to tamoxifen. These findings are of vast clinical significance, elucidating the potential for loss of TET2 expression as a biomarker to predict the resistance to anti-estrogen treatment. Additionally, these findings offer a new avenue of restoring TET2 activity to treat breast cancer patients exhibiting intrinsic resistance to hormone therapy.
[the_background] => TET2, a DNA demethylation enzyme, commonly found in the mammary gland, plays a pivotal role in regulating mammary stem cells' (MaSc) homeostasis. MaSC generates progeny cells responsible for the formation of the mammary gland. Past research has very much linked suppression of TET2 to impaired, cancer-like cell division through in-vitro studies. However, little is known of the role of TET2 in regulating MaSC homeostasis and tumor development in-vivo. CMU researchers have found that loss of TET2 expression could result in impaired differentiation from MaSC to the inner cell lining of the mammary gland, leading to the development of aggressive breast cancer using a mouse model. Therefore, findings from this study offer insight into a new role of TET2 in the development of breast cancer and resistance to anti-estrogen treatment.
[the_sdg_impact] => The past five years have seen approximately 7.8 million women diagnosed with breast cancer, with a staggering 685 000 deaths reported globally just last year (WHO, 2021). There is an urgent need for early detection, rapid diagnosis, and effective treatment methods considering how breast cancer accounts for the highest prevailing form of cancer. This study offers potential in fulfilling Sustainable Development Goals (SDG) 3.4, calling for reducing one-third of mortality caused by non-communicable diseases like breast cancer. Its findings on the role of TET2 can be regulated favorably to promote response towards tamoxifen. Likewise, it provides the potential for detecting hormone therapy resistance using the loss of TET2 as a biomarker.

[the_novelty] => This research revealed an antibiotics-induced cellular pathway that could effectively kill tumor tissues. The mechanism occurs when the cells are deprived of oxygen, whereby nuclear-programmed death-ligand 1 (nPD-L1) enables pyroptosis (instead of apoptosis) programmed death in cancer cells. Sequentially, it involves interactions between p-Stat3 and nPD-L1, transcription of the gasdermin C (GSDMC) gene, cleavage of GSDMC by caspase-8 (activated by TNFα), and, eventually, death of cancer cell due to pyroptosis. Unlike PD-L1, the role of nPD-L1 in this particular anti-tumor pathway did not involve any checkpoint inhibitor. Further investigation can be conducted to study its feasibility in treating different types of cancer.
[the_background] => PD-L1 is usually located in the cell surface and has been a common target for checkpoint inhibition immunotherapy. Meanwhile, little is known of the exact role and purpose of PD-L1 located in the nucleus (i.e., nPD-L1). Compared to apoptosis (a cell’s natural mechanism for programmed death), pyroptosis (an inflammatory programmed cell death) in cancer cells showed more promising results in killing tumor tissues. Upon determining the function of nPD-L1, this research demonstrated nPD-L1’s ability to mediate the switch from apoptosis to pyroptosis, which successfully killed tumor tissues under hypoxia. These significant findings show high potential in the development of a new anti-cancer therapy.
[the_sdg_impact] => There are more than 100 types of cancer, which implies humans' high vulnerability towards cancer. Hence, cancer-related studies are essential not only for increasing patients’ survival rates, but also to provide advanced knowledge of the human body, especially the immune system. The new method to kill cancer cells discussed in this study is a valuable effort to support the research and development of cancer treatment (UNSDG 3: Good Health & Well-being).

[the_novelty] => This study identified a molecular mechanism responsible for promoting the survival of exhausted T-cells, which resulted in higher antitumor activity. Apart from its commonly known functions, programmed cell death protein 1 (PD-1) was able to inhibit the induced death of exhausted T-cells by binding to galectin-9 ligand (Gal-9). While letting the exhausted T-cells sustain their role in immunity, the inhibition of Gal-9 could also be a high-potential antitumor therapy, as indicated by in vitro studies. Thus, further investigations emphasizing anti-Gal-9-based cancer therapy are very likely to lead to the development of various therapies for treating a broader spectrum of cancer.
[the_background] => T cells exhaustion occurs during chronic infections and cancer, whereby the optimal control of infection and tumors is prevented. The two T cell inhibitory receptors PD-1 and TIM-3 (T-cell immunoglobulin and mucin domain-3) are co-expressed in this state. Consequently, the binding of Gal-9 to TIM-3 will induce natural programmed death of T cells, resulting in lower immunity. However, in the tumor microenvironment (TME), the exhausted T-cells persist instead. Hence, this study was conducted with interest to verify the speculation stating that the persistence was due to the inhibition of Gal-9/TIM-3 by PD-1. Other than the successful verification, its conclusion also highlighted that Gal-9 was a crucial target for immunotherapy. This forms a robust foundation for future studies related to immunotherapy.
[the_sdg_impact] => Being known as the second leading cause of death, cancer has been studied extensively for decades with the sole purpose of ending it ultimately. Therefore, scientists have persevered in exploring the most feasible therapies from various biological aspects to address the entire spectrum of human malignancies. With richer knowledge of T-cells, the outcome of this study has established a new research direction for immunotherapy. The contributions of this study are well-aligned with UNSDG 3: Good Health & Well-being.

[the_novelty] => By identifying recombinant ribonuclease RNase7 as the ligand which activates receptor tyrosine kinase ROS1, this study introduces a potential treatment for hepatocellular carcinoma (HCC). As a result of ligand-receptor relationship establishment between RNase7 and ROS1 based on both in vitro and in vivo studies, the ROS1 pathway involved in tumor growth was inhibited. Thus, the mechanism promises a potential treatment for patients with high RNase7 expression. With that said, clinical trials should be conducted to better understand the effectiveness of RNase7-ROS1 targeted therapy in treating liver cancer and other cancers.
[the_background] => Cell surface receptor ROS1 is involved in the formation of tumor cells. Therefore, ROS1 is often part of the main subject in studies related to human cancers. However, the ligand responsible for the activation of the ROS1 pathway is still unknown. Thus, such a gap in knowledge poses a major hurdle in developing effective targeted therapy for HCC. With reference to recent studies indicating RNase as a possible ligand for ROS1, this study successfully demonstrates RNase7 as the ligand of interest and that anti-ROS1 inhibition could potentially be used to treat HCC. Hence, serving as a significant milestone that brings oncology closer to discovering more effective cancer prevention and cure.
[the_sdg_impact] => The number of death due to cancer in 2018 has reached 9.6 million worldwide, making this disease the second leading cause of death globally. In other words, countless lives can be saved if feasible cancer treatments are developed and made accessible to all cancer patients. The discovery of the ROS-1 inhibition mechanism and its relationship with tumor growth provides great insights into potential HCC treatment. Such progress aligns with the objectives of UNSDG 3: Good health & well-being by propelling cancer treatment research development forward.

[the_novelty] => Human platelet lysate (HPL) has been extensively explored for cell therapy and regenerative medicine as a suitable and effective substitute for fetal bovine serum (FBS). Hence, an internationally standardized quality control protocol is needed to manage the production, safety, and quality criteria. As an attempt, this study evaluated existing literature on HPL production and outlined necessary guiding steps to ensure the maximal safety of this ancillary material. It emphasized that there should be an evaluation at all stages, including blood donation, production of HPL, and risk assessment of viral safety. Above all, HPL manufacturers should ensure the quality of PC used in their production, and the HPL manufacturing facilities should meet the standards set by the Good Manufacturing Practice (GMP) protocols.
[the_background] => Until recently, FBS has been the go-to supplement medium for external experimentation to propagate stromal cell-based medicinal products. However, due to its animal-based origins, there are concerns about the immunological and infectious safety of FBS’s use in cell therapy and regenerative medicine. Given such circumstances, HPL is now emerging as the most viable alternative to FBS as it alleviates this concern. HPL-medium also proved to provide better cell expansion with a shorter doubling time in the expansion of mesenchymal stromal cells (MSCs) from various tissues compared to an FBS-medium and does not stimulate tumorigenicity in vivo. Therefore, the role of HPL in biotechnology and cell therapy is predicted to expand. With that, the need for a consensus on quality and safety criteria is crucial. This study reviews and highlights specific measures proposed to achieve this consensus.
[the_sdg_impact] => There have been growing concerns about FBS use in cell culture media, largely due to the biosafety aspect, the global demand, and an ethical standpoint. The FBS market is loosely regulated, and many cases of fraud have occurred. In 2015, GE Healthcare teamed up with a New Zealand-based company to detect the origin countries of FBS. This is crucial as different countries of origin pose different viral risks. Based on UNSDG 9: Industries, Innovation, and Infrastructure, which aims to promote economic growth through innovation, infrastructure, and industrialization, HPL provides an innovative alternative to FBS. It also appears to be more efficient when used in cell expansion comparatively, improving the production of stromal cell-based medicinal products. FBS depends on many factors that can reduce its production; hence, according to UNSDG 12: Responsible Consumption and Production, HPL is a better alternative as its supply is more sustainable in the long term, and it avoids the wastage of precious human blood resources.

[the_novelty] => Western epistemology has always been an integral part of modern society and constantly shapes the deeply-rooted ideology within the global community. Consequently, we have been dismissing the dissemination of knowledge based on different cultural and language entities, especially those of the indigenous people. Hence, this study reinstitutes an alternative mindset by pivoting on the “Millet Ark” initiative, a Tayal community’s millet biodiversity conservative endeavor that effortlessly connects the community, nature, and culture. This “indigeneity retrieval” effort began in 2013 and initiated the realization of the grassroot network involving two of the authors (Pagung and Yih-Ren Lin) and a few members of Taiwan indigenous people and mountain farmers from nine other countries in Bhutan through walking workshops. Inspired and influenced by this experience, Pagung decided to revive long-left millet cultivation in her village. The study assimilated the spirit of the indigenous community, wherein most of the findings were derived using the walking and storytelling culture of indigenous people. The success of Pagung in reinstating Tayal millets in the past five years is evident from the growth of the project from one plot of land to a remarkable landscape of the village, and the millet conservation movement is only continuing to expand by the day.
[the_background] => The main aspiration of this study is to revive the values and practices of the indigenous community of Taiwan, particularly the Tayal ethnic group, via exploring the indigenous resilience, which is so brilliantly elucidated via the “Millet Ark” conservation narration. Indigenous resilience is defined as a dynamic process of cultural and ecological adaptation and alteration in response to climate change that is imperative in ensuring the survival of human and non-human species without losing the ethos of a culture. The main limitation in the study is the possible loss of essence that happens in translating indigenous stories or songs into English or Chinese. To retain the gist of the native stories, the authors tried their best to translate the ideas instead of words and accepted a certain level of untranslatability as the power of the alternative ideology that challenges mainstream which is the very purpose of this study. This study is so uniquely crucial as it is proof that the indigenous practice like Tayal millet foodscape sustained the bio- and cultural diversity, enhanced human-nature connection, and fostered complex adaptive system thinking, which is all we need in facing the climate change issue.
[the_sdg_impact] => An undeniable but relegated truth is that the indigenous people are among the first to face the consequences of climate change due to their co-dependence on nature. The severity of this issue was proven when the special theme of the 7th session of the United Nations Permanent Forum on Indigenous Issue (New York, 2008) was “Climate change, bio-cultural diversity, and livelihoods: the stewardship role of indigenous peoples and new challenges.” Consistent efforts are needed to mitigate the continuous repercussions faced by the indigenous community in the face of climate change, which is why this study sets a precedent in this matter. Thus, this effort upholds not just one but three vital United Nations Sustainable Development Goals (UNSDG); Goal 13: Climate action, Goal 15: Life on land, and Goal 17: Partnership.

[the_novelty] => Non-hypophysiotropic gonadotropin-releasing hormone (GnRH) neurons are commonly found in vertebrates. This review concluded that the non-hypophysiotropic GnRH neurons play an essential role in modulating neural circuits, depending on the internal condition or the external environment. They are involved in regulating major activities, such as behavioral motivation, food intake, and sensory reception, rather than just reproduction. For future studies, the authors planned for in vivo studies to investigate the timing and functions of the non-hypophysiotropic release of GnRH and cotransmitter. Furthermore, they aim to study the significance of non-hypophysiotropic neurons projecting to broad brain regions release GnRH and other cotransmitter(s).
[the_background] => Neuromodulation is the function to modulate neural activities in regions to which the releasing hormone neurons project. In vitro studies of the brain showed that non-hypophysiotropic GnRHs were neuromodulating various sensory processing pathways. However, the functions of non-hypophysiotropic GnRH neurons in the daily activities of organisms were unclear. To understand those functions, this review summarized the anatomical and physiological properties of non-hypophysiotropic GnRH neurons and discussed their roles in vertebrates, mainly teleosts. The summary establishes an in-depth understanding of non-hypophysiotropic GnRH neurons. The analysis enhances the literature on vertebrates’ anatomy and physiology.
[the_sdg_impact] => New findings and reports related to vertebrates’ anatomy and physiology are valuable, especially for medicine and veterinary. The knowledge would contribute to improving the well-being of most living beings. Therefore, the output of this review helps to achieve UNSDG 14: Life Below Water and UNSDG 15: Life on Land by emphasizing the sustainability of vertebrates.

[the_novelty] => To date, several aspects of dicyemid mesozoans’ lifecycle remain uncertain. In this study, the gene expression profiles characterization conducted at different life stages reveals new information of various biological processes of the organism. More genes were expressed in free-living infusoriform larvae when compared across the four life-cycle stages, primarily due to its need to search for new hosts in the open ocean. Neurotransmitters and neuropeptides, as well as short cilia, served as sensory functions for detecting new hosts. With that said, the experimental techniques employed in this study would be beneficial to other research on simple organisms and understanding their biological mechanisms.
[the_background] => Despite having a bare 30-cell composition as an adult, the life-cycle of dicyemid mesozoans has yet to be fully understood. It is known that there are four stages in the entire lifecycle of dicyemids, namely nematogens, vermiform larvae, rhombogens, and infusoriform larvae. Since obtaining samples of infusoriform larvae from the ocean has been a great challenge, researchers were unable to grasp how the larvae search for new hosts. Besides that, the infusoriform larvae’s sensory mechanism is obscure since they do not have a nervous system. By characterizing the gene expression profiles of the four stages of Dicyema japonicum, the biological functions of the dicyemid stages and potential sensory functions for detecting new hosts were discussed in detail in this study. The study of gene expression profiles showed great potential in understanding the significance of different life-cycle stages of organisms.
[the_sdg_impact] => Dicyemida is a tiny parasite that lives in the renal appendages of cephalopods like squid, octopus, cuttlefish, and many more. Since these aquatic animals are crucial to maintain the balance of the marine ecosystem and serve as food sources, it is vital for the infection mechanism of the parasites they carry and the effects on the host to be clearly understood. Generally, research on parasites is challenging due to their simplified morphology and complex lifecycles. Therefore, the techniques adopted in this study could be useful in facilitating further exploration of parasitism in other organisms. Indirectly, it contributes to the realization of UN SDG 9: Industries, Innovation & Infrastructure by supporting technology development, research, and innovation.

[the_novelty] => This study proposed a potential novel type of self-marker protein involved in the self and non-self-cells distinguishing mechanism in Halocynthia roretzi (sea pineapple) hemocytes. By examining the contact reactions (CR) of sea pineapple hemocytes, the membrane proteins (HrSMLP1) have been identified as responsible for the hemocyte’s role in allorecognition. A monoclonal antibody (mAb11B16B10) was synthesized to induce CR in hemocytes. As a result, phenol oxidase (PO) was released, which served as an important indicator to identify the self-marker proteins. The findings provided comprehensive insights into the allorecognition mechanism of invertebrate H. roretzi.
[the_background] => Allorecognition is part of the immune response of an organism to distinguish its tissues from those of another individual. There are three commonly recognized allorecognition types in ascidians, self-incompatibility, fusion/non-fusion reactions, and contact reactions (CRs). Past studies have successfully classified hemocytes in sea pineapples (H. roretzi) to be able to differentiate into nine different cell types, among which were due to CR. Thus, this study hypothesized that self-marker molecules are present on the surface of hemocyte membranes, and that PO-inducing levels change in response to changes in the state of self-marker molecules. However, there is a lack of evidence in terms of genetic data to support such claims to date. Therefore, this study investigates the allorecognition mechanism of H. roretzi by exploring the hemocyte structure and trigger. The findings serve as good references to understand the evolution of the immune system and the roles of self-marker proteins in organisms.
[the_sdg_impact] => Comprehensive knowledge of organisms and their biological mechanisms is essential to maintain the balance and enhance the natural ecosystem. Understanding the immune system that aids the evolution and survival of vertebrates and invertebrates brings conservatory measures a step closer. The findings of this study, which revealed new information of biomarkers vital to self and non-self-cells distinguishing mechanisms in marine organisms, such as H. roretzi, would potentially contribute to the realization of UNSDG 14: Life Below Water.

[video] =>
[the_novelty] => For insects and other invertebrates, the spectral tuning mechanism of their color vision is largely unknown. To shed some light on this matter, this study adopted a methodology previously developed by the research group known as heterologous action spectroscopy. This technique revealed that two amino acids at positions 116 and 120 in helix III of butterfly Papilio xuthus long-wavelength-sensitive (LWS) opsins play a significant role in its spectral tuning mechanism. The helix III yielded a difference of about 15 nm in the wavelength of absorption maxima of PxRh1 and PxRh3 LWS opsins. With such detailed results, heterologous action spectroscopy has proven to be a promising method for examining invertebrates' visual systems, and its application could potentially be extended to understand other invertebrates.
[the_background] => Spectral tuning in visual systems of organisms is a crucial ability to sense a wider range of visible light wavelengths. This ability is closely related to opsins, a group of proteins made light-sensitive via the chromophore retinal found in photoreceptor cells of the retina. Past studies have indicated that distinct spectral tuning mechanisms are employed in the visual opsins of vertebrates and invertebrates. However, the tuning mechanism of invertebrates remains unclear due to the challenges in obtaining purified recombinant pigments. In fact, at present, there is no adsorption spectrum of the butterfly color-opsin available too. Therefore, this study adopts the heterologous action spectroscopy technique to obtain the absorption spectra of wild type PxRh1 and PxRh3 LWS opsins which share 81.7% amino acids. Besides confirming a spectral tuning mechanism different from primate LWS opsins, this method also reveals the potential spectral tuning mechanism in butterfly LWS opsins.
[the_sdg_impact] => Efficient research methodologies and equipment are the keys to the advancement of scientific research. This study proved the usefulness of heterologous action spectroscopy in understanding the visual system of invertebrates, which was initially challenging. Such development in research techniques does not just provide in-depth knowledge of previously unknown biological mechanisms of invertebrates, but also models an innovative future for scientific research methodologies.

[video] =>
[the_novelty] => The novelty of this study is attributed to its environmentally friendly method of controlling insect activity within public spaces in sub-arctic climate regions. An extensive field survey based in Hokkaido found that different wavelengths of light and weather conditions affected insect activity. In specific, aquatic insects and winged ants were drawn to broadband light wavelengths while moths and beetles were attracted to short light wavelengths. An examination of weather parameters among Gypsy moths and Japanese oak silkmoths revealed that Gypsy moths were positively correlated with the highest ambient temperature on the catch day. Especially, suitable range (22-24 ˚C) of dusk temperature promoted their synchronous mass flight. 380 nm LED, which is more cost-effective and energy-efficient than UV LEDs (<370 nm), was sufficient for capturing both moth species.
[the_background] => Insect outbreaks not only affect agriculture but can also be an aesthetically and practically unpleasant experience, especially within commercial spaces. Past studies neither tackled the influence of weather factors on insect activity nor were they applicable to commercial settings. Therefore, this study performed a 4-year long insect survey using light traps to observe different species of insects. The study then manipulated LED light wavelengths to observe light orientation among different species, besides weather variables. Findings from this study serve as an environmentally-friendly guide to manage insect outbreaks.
[the_sdg_impact] => The United States Department of Agriculture highlights the influence of climate change on forest insect outbreaks. Therefore, there is a need for sustainable measures that incorporate the climate to curb insect outbreaks without entirely relying on it. As proposed by the United Nations’ Sustainable Development Goal 15, specifically target 9, this study successfully integrates light technology and weather factors to curb insect outbreaks in local commercial spaces without known damage to the environment.

[video] =>
[the_novelty] => Would it be possible for a detector to accurately detect weak nuclear reactions signal in the HIL-induced plasma environments without being affected by the induced high electromagnetic pulse (EMP)? This study has developed a gated fiber detector (GFD) which was meant for that purpose. The main structure of the GFD included a reflective layer, a scintillating layer, a vacuum sealing glass window, a photon coupling cone, a fiber, and a gated photomultiplier tube (gPMT). Based on the results from numerical simulation, the optimal light-collecting efficiency was achieved in the development, which maximized the number of photons to be coupled by fiber and then transferred to a light detector (i.e., gPMT) located far away from the EMP source. Online tests confirmed that the detector was performing up to expectation and its response time was as short as 70 ns. Future optimization could be explored by collecting feedback from actual utilization.
[the_background] => The demand for studying nuclear reactions in laser-induced high-temperature plasma environments is increasing. Nevertheless, extremely high EMPs are commonly induced in such environments, thus crippling the functions of many traditional detectors. To overcome these complications caused by EMPs, this study has designed a detector that potentially avoids the effect of EMPs, yet still, be capable of identifying a single event of nuclear reaction products. By overcoming the EMPs, the detector was feasible to be utilized as time-of-flight (TOF) detector in high-intensity laser nuclear physics experiments. Such a development would help to achieve the goals of various studies related to laser nuclear physics.
[the_sdg_impact] => The potential of laser-induced nuclear physics has attracted a considerable amount of attention. With continuous progress and development, it is believed to be a window for new technologies in multidisciplinary. Apart from eliminating the hurdles caused by EMPs, this development also creates opportunities to widen the direction of studies related to laser nuclear physics. Hence, by enhancing the progress in peacefully using laser and nuclear techniques, this study materialized the UN SDG Goal 9: Industry, Innovation & Infrastructure.

[the_novelty] => Is it feasible to perform measurements at accelerators using the isotope separator on-line (ISOL) technique? This study confirmed the feasibility by performing the first-ever proof-of-principle experiment with a post-accelerated 23Na beam (using the ISOL technique). Such was primarily made possible by measuring the angular distribution of 23Na + 40Ca elastic scattering. The angular distribution measured showed consistency with the high-precision Q3D magnetic spectrograph measurements (using non-ISOL beam). Thus, this breakthrough enables researchers to explore the potential properties of non-stable Na isotopes by measuring the angular distribution of 21,22Na + 40Ca elastic scattering.
[the_background] => A nuclear drip line is a boundary delimiting the zone beyond which atomic nuclei decay by the emission of a proton or neutron. Nuclei with short life, unstable, radioactive are known to be exotic when they develop unusual structures. Meanwhile, the reaction dynamics of light exotic nuclei near the drip line have been getting significant attention, especially from the low-energy nuclear physics community. Several important properties of exotic nuclei include the size and surface diffusiveness which can be determined using elastic scattering. Such measurements were commonly performed at accelerators using the projectile fragmentation technique. However, reported studies that applied the ISOL technique for the same purpose were rare. By presenting the above-mentioned proof-of-principle experiment conducted at the Beijing Radioactive Ion Beam Facility (BRIF), the potential and feasibility of the technique were proven in this study. Furthermore, the output of this research gave validation for scientists to apply the ISOL technique in relevant investigations of the reaction dynamics of exotic nuclei.
[the_sdg_impact] => The properties of exotic nuclei can become very different from those of stable isotopes. That implies the existence of unexplored applications of exotic nuclei in nuclear technology. By introducing a highly reliable technique for the characterization of nuclei, this study established a strong foundation for future studies of exotic nuclei. Hence, it contributes to the realization of UNSDG 9: Industries, Innovation & Infrastructure by supporting future research related to nuclear science.

[the_novelty] => The mass measurements of short-lived nuclei require advanced facilities as well as high-level knowledge and skills. This study reports a new analysis method for isochronous mass spectrometry (IMS) experiments that led to significant improvements in charge resolution for ions. By considering the signal amplitudes, detection efficiencies, and the number of stored ions in the heavy-ion storage ring, ion pairs with nearly identical mass-to-charge (m/q) ratios can be resolved in terms of their revolution times. The new method enabled a complete resolution of 34Ar and 51Co in this study. Additionally, a consistent mass excess of 51Co was determined.
[the_background] => IMS of heavy-ion storage rings is a powerful technique to measure the mass of short-lived nuclei. Its working principle relies highly on its ability to measure the revolution times of ions precisely. Nonetheless, there was a limitation in the measurements for pairs of ion species with nearly identical m/q ratios. To address this, the researchers analyzed the amplitudes of the timing signals from the detector based on the emission of secondary electrons in a previous study. The introduction of a new analysis method was able to deduce revolution times with differences as low as 1.8 ps. This led to a higher charge resolution, enabling the complete resolution of 34Ar and 51Co (A/Z = 17/9). The new analysis method would facilitate the progress of other atomic and nuclear physics experiments using similar types of detectors.
[the_sdg_impact] => Nuclear technologies are useful to meet some of the fundamental needs of modern daily life. These include access to energy and proper medical care, food production, water resources management, and many more. Having effective methods to study exotic short-lived nuclei could open up endless possibilities for further exploring nuclear technology applications. The new analysis method reported by this study has enabled accurate characterizations of short-lived nuclei. Its contributions, aligned with UNSDG 9: Industries, Innovation & Infrastructure, promises the enhancement of scientific research necessary for upgrading existing and future nuclear technological capabilities.

[video] =>
[the_novelty] => This study highlights the development of a whole slide training method to train convolutional neural network (CNN) for pathological classification of lung cancers. This method is superior to the existing digital diagnosis methods, such as the multiple-instance learning (MIL) method. A total of 7003 slides were gathered, consisting of 2039 cases of non-cancer, 3876 of adenocarcinoma, and 1088 cases of squamous carcinoma. The slides were randomly assigned for training, validation, and testing purposes. The slides were then subjected to different model performance testing to study various parameters in image analysis in lung cancer. In this study, whole slide imaging (WSI) used recorded superior results to MIL in terms of visualization, small lesion diagnosis, image resolution (despite the impact of data size), and memory consumption. Provided that there’s a limitation on host memory when training larger images on CNN, future research to identify a more memory-efficient algorithm will further optimize the model in the digital diagnosis of diseases.
[the_background] => CNN is a deep neural network in artificial intelligence (AI) designed for image analysis. It is a deep learning algorithm representing image input, extracts the importance of every bit of the image (each neuron), and distinguishes one image from another. In nonsmall-cell lung cancer (NSCLC), proper pathological diagnosis to differentiate between adenocarcinoma and squamous cell carcinoma presents a challenge, as the difference in pathological features between them is subtle. Hence, CNN has been the primary method used in image recognition in distinguishing these two histologically different NSCLC subtypes. Despite its success in tumor type identification and classification, the path-based CNN method demands substantial annotations on the slides by experienced pathologists. MIL, another technique employed to reduce the annotation burden, is subject to incorrect selection of patches for diagnosis or classification in early training, leading to compromise in the model’s performance. To overcome the limitations of existing methods, this study proposes using WSI to train CNN utilizing slide-level labels, the outcome of which intends to prove the superiority of this approach.
[the_sdg_impact] => Since the introduction of WSI in 1991, it has achieved remarkable growth in technology and is recognized in various applications in pathological diagnosis. The approval of the US FDA to a WSI system for primary surgical pathology diagnosis in 2017 has paved the way for the acceptance of this technology for broader medical applications. Given that the health demand is increasing by the day, non-laborious, highly efficient technology is snatching importance in enhancing diagnosis and disease classification processes. Thus, the utilization of WSI to train CNN in the diagnosis and classification of lung cancer becomes imminently crucial and contributes to the realization of United Nations Sustainable Development Goal (UNSDG) 3, good health and well-being.

[video] =>
[the_novelty] => This study investigated the intricate relationship between cancers, anti-cancer treatments, and SARS-CoV-2 infection to understand possible modifications needed for the clinical management of cancer patients. Large-scale genome-wide transcriptional analysis revealed that RNA expression of three significant genes responsible for SARS-CoV-2 entry into cells, including ACE2, TMPRSS2, and CTSL, were upregulated in different cancer tissues assessed. These viral entry genes were also upregulated in male patients and those who smoke and transiently increased during radiotherapy. In addition, chemotherapy and radiotherapy both transiently dysregulated the immune system in cancer patients. These alterations possibly predisposed this cohort to higher susceptibility and severity of COVID-19. Findings from this study urge further investigation of the complex relationship between cancers and COVID-19 to optimize treatment strategies for both diseases in cancer patients.
[the_background] => Similar to the closely related SARS-CoV, SARS-CoV-2, the novel coronavirus responsible for COVID-19 mainly relies on the angiotensin-converting enzyme 2 (ACE2) type I membrane protein, host cell serine protease transmembrane protease serine 2 (TMPRSS2), and endosomal cysteine protease cathepsin L (CTSL) to enter target cells. The expression of these proteins allows SARS-CoV-2 infection, which then triggers host antiviral response. However, SARS-CoV-2 can also deregulate the immune system, leading to a hyperinflammatory reaction with cytokine over-production that contributes to COVID-19 progression and severity. Based on the increased prevalence and severity of COVID-19 in cancer patients reported in multiple previous cohorts, this study aimed to examine the expression of SARS-CoV-2 entry genes in various cancer tissues and the effect of radiotherapy and chemotherapy on these viral entry genes and host immune responses.
[the_sdg_impact] => COVID-19 pandemic has caused over 150 million cases and approximately 3 million deaths worldwide as of mid-2021. Cancer patients are four times more likely to be infected by SARS-CoV-2 than the general population, making it a big concern to both patients and oncologists. Hence, identifying risk factors of COVID-19 in cancer patients is vital to reducing morbidity and mortality in this group. In line with that, the findings of this study are imperative to guide clinicians and oncologists on the management of cancers during the COVID-19 pandemic to alleviate potential complications that could impose a huge health burden on the global health system. Ideally, such an endeavor is crucial to uphold the UNSGD 3: Good health and well-being, aiming to improve global health and, thus, global public health. With the pandemic being the current health emergency globally, every effort at improving its management becomes an integral part of fighting the battle.

[video] =>
[the_novelty] => This study elaborates the algorithms, implementations, and applications of a new computer-aided design (CAD) model to Monte Carlo geometry converter (CMGC). This newly developed conversion code promises highly efficient Monte Carlo simulations by generating appropriate constructive solid geometry (CSG) representation. As a result, this automatic conversion can produce heuristic strategies for solid splitting, reduce the time taken for particle transporting, provide low relative volume error, and has a friendly graphical user interface. At the end of the CMGC conversion, the converted models show high accuracy and improved efficiency in particle transport calculations.
[the_background] => The computer-aided design (CAD) model to Monte Carlo geometry conversion is recognized as the most effective automatic conversion method compared to the conventional boundary representation model. Recent researches have been heavily focused on improving the efficiency of large-scale and detailed Monte Carlo modeling. Among the areas of focus are to reduce manual work, increase conversion speed, and improve conversion accuracy. This study aims to provide an in-depth analysis of a new conversion method and demonstrate its improved Monte Carlo simulation efficiency.
[the_sdg_impact] => The Monte Carlo methods are very common and preferred when designing sophisticated nuclear systems due to their capability of dealing with complex problems with high accuracy. Radiation technology and computational medicine physics, among other fields, are known to benefit from an efficient and safe interface such as the CMGC model mentioned in this study. Therefore, the detailed description in this study would serve as a good reference for future infrastructure upgrading with increased resource-use efficiency and accuracy, as proposed in the 9th UN Sustainable Development Goal: Industry, Innovation and Infrastructure.

[the_novelty] => To meet the high requirements of sophisticated studies in condensed matter physics, this research has successfully designed and constructed a more advanced synchrotron angle-resolved photoemission spectroscopy (ARPES) beamline (BL03U) and an endstation at the Shanghai Synchrotron Radiation Facility (SSRF). The BL03U endstation consists of an ARPES system, a load-lock chamber, an oxide molecular beam epitaxy (OMBE) system, a scanning tunneling microscopy (STM) system, and a UFO-like transfer chamber. The beam spot produced by the ARPES system is as fine as 7.5 um (V) × 67 um (H) with the fundamental photon range of 7 to 165 eV. Photoemission with an energy resolution of 2.67 meV (at 21.2 eV photon energy) was achieved by the newly developed ARPES system. By equipping the ARPES system with a six-axis cryogenic sample manipulator (minimum temperature of 7 K), the BL03U endstation provides an essential platform to carry out in-situ characterization of the electronic structure of condensed matter. Such a development has demonstrated the versatility of an ARPES endstation to be enhanced to support future studies in condensed matter physics.
[the_background] => Conventional ARPES is well-known for its capability in characterizing the electronic properties of correlated materials and the electronic structure of correlated electron systems. Nonetheless, conventional ARPES faced several bottlenecks when it was applied in the recent development of quantum materials which has higher characterization requirements in terms of photon energy, flux, and beam spot. Besides that, quantum material samples with a flat surface along the desired crystalline orientation were difficult to be prepared for characterization under ARPES. To address these limitations, a more superior ARPES endstation has been developed by this study. Furthermore, with the OMBE system and connected growth chamber, epitaxial growth techniques are able to be applied to realize in-situ ARPES measurements without the need for tedious sample preparation. By having the state-of-the-art features, this facility will boost the advancement of studies in condensed matter physics.
[the_sdg_impact] => The improvement of ARPES will help condensed matter physicists to better understand the behavior of more exotic condensed phases include the superconducting phase exhibited by certain materials at low temperature. More experiments can be conducted using the improved facility to measure various material properties, and by applying the physical laws of quantum mechanics, electromagnetism, statistical mechanics, and other theories to develop mathematical models. Such innovative facility is a great contribution to the research infrastructure that supporting and aligning to the UNSDG 9: Industries, Innovation & Infrastructure.

[video] =>
[the_novelty] => This study provides evidence of the increase in digital dependency, usage, and literacy among the elderly community when seeking health information. The most common information searched online is on diseases and disease-related nutrition advice. Consistent with previous findings, elderly people prefer using the internet to search for health information because of accessibility and convenience. However, the amount of information presented can be overwhelming with risks of misinformation if they are uncertain of how to identify the right source. Therefore, health information providers should consider the internet as a source of knowledge dissemination and support the elderly population by directing them to official channels to seek information. Such behavioral understanding could potentially be expanded into monitoring and surveillance of the aged community.
[the_background] => The ‘Dr. Google’ phenomenon is widely observed with the growing internet accessibility. Apart from encouraging social interaction and collaboration, the internet has become a reliable channel for many to continuously learning about their health and seek advice to improve their conditions. As the elderly community is among those most prone to a range of diseases and illnesses, seeking quick and comprehensive information on their health becomes the priority when using the internet. Having said that, little is known of the Malaysian elderly behavior when it comes to internet dependency and online health information-seeking habits. Therefore, this study chose to profile residents of 23 Elderly Activity Centres across Malaysia to understand the online health information-seeking pattern of the elderly.
[the_sdg_impact] => Graceful and healthy aging could be supported with the right tools and systems in place. With health-related information being shared openly and rapidly on many online platforms, knowledge accessibility has certainly improved over the years. In order to protect and support the elderly population in having access to such valuable information and promote lifelong learning, health staff should encourage digital health literacy for older adults as foundations for learning and decision-making (SDG 4: Quality education). With that, the elderly community would not be left out in terms of accessing information on disease prevention, treatment, and rehabilitation to maintain their health and independence (SDG 3: Good health and well-being). However, to work on the mentioned areas, health information providers and policymakers should first understand the digital usage patterns and behaviors of the elderly community. The data offered by this study would be useful to design a more efficient and effective health information dissemination medium.

[video] =>
[the_novelty] => The findings of this study contribute to a regional understanding of how diabetic patients manage their medications and why they choose to opt for herbal medicine instead of relying on clinic prescription. Focused mainly on patients undergoing treatment for Type 2 Diabetic Mellitus (T2DM), it was found that these patients are more inclined to incorporate herbal medicine to complement their conventional treatment regimen. Some have even chosen to alter the dosage and consumption timing of conventional medication to cater to their herbal medicine consumption timing, while some even consider quitting their clinical prescription and relying entirely on herbal treatment. These decisions result from a lack of confidence towards the effectiveness of synthetic drugs, their side effects, and the influence of family and friends. By understanding the patient perception towards conventional and herbal medicine, healthcare providers and policymakers could improve diabetes management to ensure medication safety.
[the_background] => Living in a multi-cultured society and growing preference towards natural products, it is becoming challenging for healthcare personnel to restrict their patients from seeking alternative treatment. The long-term reliance on existing synthetic drugs, slow observable results, and negative side effects have led more T2DM patients to choose herbal medicines over conventional medicine. At present, there are limited qualitative research data available that elaborates the reasons for what triggers such choices among patients. Therefore, this study intends to generate a detailed understanding of the perception, beliefs, and values of the T2DM patients in deciding their preferred treatment. With this knowledge, pharmacists and doctors could cater their medical advice to meet the needs and beliefs of their patients accordingly.
[the_sdg_impact] => The rate at which people are being diagnosed with T2DM is alarming; even more concerning is the attitude of these patients towards managing their conditions post-diagnosis. Diabetes control is part of the UNSDG 3, Good health and well-being, target, to reduce premature mortality and disabilities due to non-communicable diseases by 2030. To combat this global epidemic, multisectoral population-based research is crucial to prevent and manage this disease. This study allows healthcare providers and policymakers to understand patients’ sentiment towards the treatment regimen to improve the monitoring and educating process.

[the_novelty] => This study delineates patients’ experience in receiving health education services given by healthcare providers (HCPs) in clinics that have adopted the Enhanced Primary Health Care (EnPHC) initiative. As a whole, patients recognize the intention of including such intervention components and are willing to engage with HCPs in educating themselves to cope with their illnesses. However, they wish to have certain concerns and challenges to be addressed before fully reaping the benefits of the service provided. Among the factors identified to have caused patient scepticism towards receiving health education at secondary triage are the prolonged waiting period, lack of privacy at waiting area, repetitive message delivery, interpersonal relationship between patient and the health educators and the confidence in their credibility. Therefore, to ensure the effectiveness of the EnPHC initiative in educating the patients and supporting them in coping with their medical conditions, these feedbacks should be considered and acted upon by clinic management and health educators.
[the_background] => The introduction of the Enhanced Primary Health Care (EnPHC) initiative by the Malaysian government is to assist patients in coping with the complexity of living with non-communicable diseases (NCDs). With patient-centric service delivery as the primary motive, providing comprehensive health education and increasing patient awareness are identified as key components for the successful implementation of the EnPHC initiative. Although the intentions of including these components are clearly to benefit the patients, there is little knowledge of how the patients are perceiving such changes. Therefore, this study aims to understand patient perception and experience as recipients of health education at secondary triage. These feedbacks could then be used by the clinic management, health educators, and policymakers to improve the service delivery mechanism.
[the_sdg_impact] => According to the World Health Organization (WHO), preventing premature deaths and disabilities from non-communicable diseases (NCDs) is possible, cost-effective, and necessary for human and economic development (SDG 3: Good health and well-being). As the Malaysian healthcare system is currently undergoing transformation to improve the country’s essential healthcare service delivery, equipping the patients with sufficient knowledge about their illnesses and coping mechanism is considered as one of the most cost-effective interventions. The feedback gathered from this study would, thus, be useful for healthcare service providers to improvise the intervention delivery approaches.

[the_novelty] => This study is part of a larger process evaluation study which intended to assess and report the effectiveness of the Enhanced Primary Health Care (EnPHC) initiative implementation in selected clinics through patient’s perception and experience. There were five main themes to which the assessment paid close attention to, namely health assessment in disease progress monitoring, patient-doctor relationship and continuity of care, professionalism in service delivery, ensuring compliance in achieving health targets, and communication skills. Based on the feedback received, although the patients were unaware of the EnPHC initiative implementation, positive responses towards the new changes were gathered. Overall, the government’s attempt to transform the existing clinic health care service delivery into more structured and detailed management by emphasizing patient-centered care is perceived as a success. However, future implementations and upgrades should focus on, first, increasing the level of awareness and improving the understanding of the intervention among patients to support their experience and increase acceptance.
[the_background] => In July 2017, the Ministry of Health Malaysia proposed implementing the Enhanced Primary Health Care (EnPHC) initiative to improve primary care intervention to cope with the rise in non-communicable diseases across the nation. The main focus of the initiative is to transform the existing clinic management into a more patient-centric system. Several changes have been put in motion to achieve the transformation, including redesigning work process in the clinic, improving community intervention through community enrolment and profiling, and smoothening the referral system between clinic and hospital. However, to ensure a favorable outcome, it is important to understand how these changes have benefited the patient experience. Therefore, this study aims to assess the effectiveness of the EnPHC implementation from the patient’s perception and experience.
[the_sdg_impact] => One of the targets of the 3rd United Nations’ Sustainable Development Goal, Good health and well-being, is to provide access to good-quality healthcare services as part of the attempt to ensure healthy lives and promote well-being for all. Accordingly, governments worldwide have pledged their commitments to meet the health needs of their people and improve the nation’s primary health care service delivery. The Enhanced Primary Health Care (EnPHC) initiative is Malaysia’s attempt to fulfil its pledge in putting the health needs of its people first. The findings of this study provide valuable information on patient experience and expectations, which could be used to ensure the continuous betterment of the nation’s healthcare system.

[the_novelty] => This research performed the first national-level cross-sectional study to determine the prevalence of psychological distress and its association with coping strategies among medical interns in Malaysia. The three major psychological distresses examined were stress, anxiety, and depression. Based on the data collected, the majority of interns experienced anxiety (39.9%) throughout their internship period, followed by stress (29.7%) and depression (26.2%). Noticeably, female and younger interns are highly susceptible to these conditions. Nevertheless, there has been an overall decline in anxiety and stress experiences compared to a previous study, which indicates the effectiveness of improvement strategies implemented during internship training in recent years. Moreover, most of these interns were found to have adopted healthy problem-focused coping strategies to get through the intense training process and psychological distress. As a whole, the data presented in this study would benefit healthcare institutions in incorporating the reinforcement of healthy coping strategies to ensure the effectiveness of medical internship programs.
[the_background] => The intensity in performing life-saving acts day-in and day-out is overwhelming for medical practitioners, especially the newbies and interns. Every now and then, Malaysian interns and HOs make headlines due to stress, depression, being bullied, etc. Most of the time, the mental strength of these interns are being challenged as they juggle between doing it right and adapting to the new pace and demands. Consequently, these medical interns experience psychological distress at one point or another and would need to learn to cope with it in a healthy manner. In Malaysia, most studies focused on a single psychological distress condition or based in a single center. Since there is a lack of national-level data on the prevalence of psychological distress, this study aims to collect the necessary data on this matter and examine the coping mechanisms used by the medical interns.
[the_sdg_impact] => Mental health issues have been identified as major public health problems affecting the health of the people not excluding the health professional themselves. Higher levels of psychological distress were seen among healthcare professionals where their poor mental health can compromise the quality of life and work performance and quality of care to patients. By addressing the psychological challenges faced by them and the importance of equipping the doctors, especially the young ones, with the right coping skills mechanism when dealing with stressful environments so that their mental well being is taken care of. This also contributes to the 3rd SDG - Good Health Well Being.

[video] =>
[the_novelty] => The primary aim of this study is to identify the factors influencing physicians’ intention to continue serving in government hospitals instead of seeking positions in the private sector. Based on the survey conducted, job satisfaction towards governance and work processes are among the leading triggers to cause resignation. One of the effective policies established by the Ministry of Health in Malaysia is the Full Paying Patient (FPP) services which did not just improve physician retention rate, but also the quality of patient care. In a way, this initiation also reduced the government’s financial burden by allocating medical subsidies only to those who can’t afford them. The evidence gathered through this study is, therefore, capable of providing policymakers with simple guidelines in implementing appropriate and flexible strategies to retain and meet the needs of the workforce.
[the_background] => Many public sector physicians consider themselves overworked and under-compensated for all the hard work that is required from them. Thus, taking up an offer at a private hospital becomes more tempting. In fact, scholars of full government scholarships would prefer to practice under private hospitals and opt-out of the bondage due to these reasons as well as the fancy work environment. In order to keep up with the growing demands in the healthcare sector, decision-makers are required to introduce effective measures to retain their rapidly depleting workforce. Therefore, studies on physicians’ motivation to stay need to be understood and incorporated into the initiatives for a better outcome.
[the_sdg_impact] => The growing medical “brain drain” and healthcare worker shortages are concerning, especially for public sectors, rural areas, and low-income countries. Public health standards and priorities are compromised due to the migration of health professionals to urban areas, private sectors, and high-income nations. Hence, human resource management decision makers must consider the factors causing such phenomena when drafting policies. The findings of this study provide evidence-based data to guide these policymakers to improve healthcare workforce job satisfaction, wages, resources, and working conditions, ultimately increasing the retention rate in the least developed countries as intended by UNSDG 3: Good health and well-being.

[the_novelty] => Based on the experience of Malaysian patients, this study highlights patient benefits from hospitals merging in the Cluster Hospital Initiative (CHI). The key benefits recognized are the changes in healthcare service, time spent on healthcare-related activities, and financial cost. After conducting interviews with Malaysian patients in these merged hospitals, researchers found that patients were satisfied with the increased availability of specialists and improved quality of care. Patients also complimented the shorter waiting time for medical procedures and consultation as well as reduced traveling time to the hospitals. Moreover, patients are pleased with the lower healthcare cost and higher financial savings as a result of this initiative. Nevertheless, this study can further expand by researching other features of this initiative, such as the healthcare personnel’s experience and assessing its efficiency.
[the_background] => Cluster Hospital Initiative (CHI), different from the conventional hospital mergers, focuses on integrating resources from a network of hospitals in the same region through a well-coordinated merger. Such practice has been widely adopted in many countries, more commonly in private healthcare systems. Malaysia only implemented the concept in 2010, inspired by evidence from other studies. Previous studies mainly focused on its impact on hospital efficiency, price and cost changes, clinical outcomes, and quality of care. However, this is one of the first studies to focus on the patients’ and caregivers’ experience after the establishment of CHI. This study intended to determine the patients’ and caregivers’ experience in the healthcare services of the CHI locations. This was done by conducting an in-depth interview with the patients and caregivers in these hospitals. This study could help create a comprehensive hospital merging system that allows all Malaysians access to quality hospital care.
[the_sdg_impact] => In an effort to support the Good Health and Well-being goal under the global Sustainable Development Goals, the Ministry of Health Malaysia aims to provide a more streamlined and cohesive healthcare delivery by utilising all facilities and shared resources. The merging of hospital services is a change in the existing way of healthcare being delivered to the people of Malaysia, therefore their acceptance and experience may provide useful insights to how the initiative can be improved for its longevity. With that in mind, this research looks into public acceptance and experience following the implementation of CHI. Ultimately, the findings could provide insights for policymakers to further strengthen the initiative towards its sustainability.
