Article Sustainable visible-light-induced degradation of antibiotic and dye pollutants in water bodies using a 2D Ti3C2 MXene-supported CoAl-LDH/ Bi2MoO6 ternary heterostructure with a synergistic 2D/2D/2D hybrid configuration and S-scheme charge transfer Environmental remediation requires the development of advanced photocatalysts for the removal of persistent organic pollutants, including antibiotics and dyes. In the present study, we report the design and fabrication of a novel ternary hybrid photocatalyst consisting of a CoAl layered double hydroxide (LDH), Bi2MoO6 (BMO), and the MXene Ti3C2 (TC) for the effective degradation of the antibiotic sulfamethoxazole (SLF) and the organic dyes Congo red and indigo carmine under visible light illumination. Characterization of the ternary photocatalyst revealed a well-integrated 2D/2D/2D heterostructure with optimized interfacial interactions, enhanced light-harvesting capabilities, and superior charge-carrier dynamics. The optimized LDH/BMO20/TC photocatalyst achieved exceptionally high degradation rates for the antibiotic and dyes with high mineralization rates, significantly outperforming the binary photocatalyst and individual components. This enhanced photocatalytic activity was attributed to an S-scheme mechanism that promoted selective recombination at the interface while preserving the strong reducing ability of CoAl-LDH and the strong oxidizing capacity of BMO. Electron spin resonance analysis confirmed the production of O2 center dot- and center dot OH radicals, while in-situ light-irradiated X-ray photoelectron spectroscopy identified charge redistribution, providing compelling evidence for the proposed Sscheme mechanism. Ti3C2 also served as an electron mediator, enhancing charge separation, accelerating electron transport, and stabilizing the heterostructure. The developed ternary catalyst exhibited exceptional reusability and robust activity across varying pH conditions and water matrices, demonstrating its potential as a versatile and sustainable photocatalyst for advanced environmental remediation and wastewater treatment.

Article Synthesis of a photocrosslinkable polyimide with a chalcone side chain and its properties as a coating material for a secondary battery separator A carboxyl-containing polyimide (PI) was synthesized with a flexible main chain. Then, a polymer reaction was conducted to introduce a chalcone side chain. The polymer reaction occurred stoichiometrically, and a high yield of the resulting photocrosslinkable polyimide (PI-Ch) polymer was obtained (91 %) along with a high molecular weight of 9.4 x 104 g/mol. The PI-Ch had a density of 1.15 g/cm3, a fractional free volume of 0.20, and a solubility parameter of 18.8 MPa1/2. Due to its low polarity, the PI-Ch was very soluble in a moderately polar, low-boiling-point solvent of THF. Moreover, the temperature required to promote 5 % weight loss was quite high at 383 degrees C, while the glass transition temperature was relatively low at 146 degrees C. The THF solution was considered to be optimal for the dip-coating method and was applied to PE separator coating. The ATR-mode FTIR analysis of the separator coated with a 1 wt% PI-Ch solution showed that the PI-Ch was coated extensively on the surface of the PE separator. Further, the photodimerization reaction of the chalcone side chain via UV irradiation was successful. The PE separator had a thermal shrinkage of 46 % before coating, which decreased to 29 % after coating and UV treatment. When coated with a 3 wt% PI-Ch solution, some of the pores in the separator were blocked, while the air permeability and average pore size also decreased. All the pores appeared blocked after coating with the 5 wt% PI-Ch solution.

Article Direct conversion process for enhancing biodiesel production from insect biomass waste This study aimed to ascertain the viability of silkworm pupae as a biodiesel (BD) feedstock. The silkworm pupal extract (31.98 wt% based on the pupae) contains impurities, including free fatty acids (FFAs) and hydrocarbons (HCs). These impurities hindered the conversion of lipids into BD using conventional methods (alkali/acidcatalysed transesterification). The BD yield via conventional transesterification was below 70 wt% due to side reactions such as saponification and hydrolysis. In response to the technical constraints inherent in conventional methods, non-catalytic transesterification was introduced. Owing to the high tolerance of non-catalytic method toward the impurities, the BD yield (91.6 wt%) was significantly higher than conventional methods. This indicated that over 99 wt% of lipids in the extract were converted into BD. The reaction time of non-catalytic method (within a minute) was also shorter than acid-(24 h)/alkali-(100 min) catalysed transesterification. To enhance the BD production, silkworm pupae were directly converted to BD, yielding 103.5 wt% (lipid basis). This implied incomplete lipid extraction or lipid loss during the extraction step. This study presents a new pathway for the valorisation of waste in the textile industry, with the potential to make a significant contribution to the establishment of a circular economy. The direct conversion method would not be limited to silkworm pupae; it has the potential to be adapted for a variety of insect-based feedstocks. By expanding its application, this method would contribute to more sustainable biofuel production and also contribute to the achievement of Sustainable Development Goal: 7 (Affordable and clean energy).

Article Improving Fault Localization with External Oracle by Using Counterfactual Execution We present FLEX, a new approach to improve fault localization with external oracles. Spectrum-based fault localization techniques estimate suspicious statements based on the execution trace of the test suite. Stateof-the-art techniques rely on test oracles that internally exist in the program. However, programs often have external oracles that observe their behavior from outside. This in turn hinders fine-grained and accurate estimation of suspicious statements in practice because the correctness of each execution can only be observed at termination. In this article, we aim to address this problem by observing counterfactual execution traces, which enable fine-grained estimation even without precise internal oracles. We observe two types of counterfactual scenarios related to different types of test cases: When the branch condition is set to a Boolean constant, (1) if most of the passing test cases still pass, we consider the newly executed statements in the branch statement as unrelated to the failure; (2) if failing test case still fails, we also consider the originally executed statements as unrelated to the failure. We evaluated the performance on widely used C and Java programs. FLEX improves the accuracy of state-of-the-art SBFL techniques on C and Java programs by 24% and 22% on average, respectively.

Article Method for estimating physical interaction forces using human-exoskeleton kinematic modelling and energy optimization Exoskeleton robots mimic the structure of the human body and are physically connected to the wearer through attachment parts such as cuffs or straps. Nevertheless, misalignment between the human body and the robot can occur due to improper wearing of the exoskeleton, the elasticity of human skin, and the geometric complexity of human joint movements. Such misalignment increases unnecessary physical interaction forces, causing discomfort and pain to the wearer. Therefore, these interaction forces should be considered when designing exoskeleton robots to ensure wearability. In this study, we propose a method for estimating human-exoskeleton interaction forces through posture prediction. The human-robot connection is modeled as an elastic element, and posture is predicted using an energy optimization algorithm. The predicted posture is then used to calculate the interaction forces. Since this method considers only the physical characteristics of the exoskeleton robot and wearer, it enables objective evaluation of the robot without the need to manufacture actual prototypes. We performed quantitative experiments using prototypes of a sensor-equipped dummy and an exoskeleton to confirm the effectiveness of the modeling method. Consequently, the proposed method is expected to reduce the time and costs associated with developing exoskeleton robots and obviate the need for human subject testing.

Article Non-Flaky and Nearly Optimal Time-Based Treatment of Asynchronous Wait Web Tests Asynchronous waits are a common root cause of flaky tests and a major time-influential factor of Web application testing. We build a dataset of 49 reproducible asynchronous wait flaky tests and their fixes from 26 open source projects to study their characteristics in Web testing. Our study reveals that developers adjusted wait time to address asynchronous wait flakiness in about 63% of cases (31 out of 49), even when the underlying causes lie elsewhere. From this, we introduce TRaf, an automated time-based repair for asynchronous wait flakiness in Web applications. TRaf determines appropriate wait times for asynchronous calls in Web applications by analyzing code similarity and past change history. Its key insight is that efficient wait times can be inferred from the current or past codebase since developers tend to repeat similar mistakes. Our analysis shows that TRaf can statically suggest a shorter wait time to alleviate async wait flakiness immediately upon the detection, reducing test execution time by 11.1% compared to the timeout values initially chosen by developers. With optional dynamic tuning, TRaf can reduce the execution time by 16.8% in its initial refinement compared to developer-written patches and by 6.2% compared to the post-refinements of these original patches. Overall, we sent 16 pull requests from our dataset, each fixing one test, to the developers. So far, three have been accepted by the developers.

Article Clinical features of secondary BPPV: A nation-wide multicenter study Background Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, and its prevalence is substantial. While primary BPPV has been well studied, the understanding of secondary BPPV is still limited.Objective To investigate the prevalence and clinical characteristics of secondary BPPV in a national multicenter retrospective analysis.Methods The study involved a retrospective analysis of medical records from 17 institutions across South Korea, between January and June 2022. We evaluated clinical features, presumed etiologies, involvement of semicircular canals, response to canalith repositioning procedures (CRPs), presence of residual dizziness, recurrence, and results of auditory and vestibular function tests for both primary and secondary BPPV cases.Results Of the total 1363 BPPV cases, 14.5% (198 patients) were categorized as secondary BPPV. The most prevalent etiology for secondary BPPV was head trauma. Secondary BPPV was associated with a higher prevalence of comorbidities including diabetes and inner ear diseases. Patients with secondary BPPV demonstrated more frequent involvement of multiple semicircular canals, necessitated a greater number of CRPs for resolution, and experienced a higher incidence of residual dizziness compared to primary BPPV cases. Furthermore, secondary BPPV patients exhibited more frequent abnormalities in auditory and vestibular function tests.Conclusions Secondary BPPV accounts for a significant proportion of BPPV cases, with distinct clinical characteristics compared to primary BPPV.

Article Neural fractional differential networks for modeling complex dynamical systems Neural fractional differential equations offer an innovative approach to modeling complex dynamical systems by integrating Caputo fractional derivatives into deep neural networks. This integration effectively captures memory effects and long-range dependencies, which are essential for analyzing irregular time series and fractal-like signals. In this study, we employ a predictor-corrector method for solution approximation, along with the Adam optimization algorithm for parameter tuning, significantly enhancing the neural networks' ability to model intricate non-local dynamics and anomalous behaviors. Our findings demonstrate that neural fractional differential equations outperform traditional models in representing the complexities of data, leading to improved predictive accuracy. By extending neural ordinary differential equations to fractional orders, this research broadens the applicability of neural networks, addresses the limitations of existing methods, and establishes a robust framework for real-world applications across diverse dynamical systems.

Article A multicriteria decision analysis for the selection and ranking of crop residue for sustainable energy generation in West Africa West Africa faces significant energy access challenges, particularly in rural areas, where limited energy supply exacerbates poverty and insecurity. Renewable energy from agricultural residues has emerged as a promising solution to address energy shortages and climate change. However, while 18 African countries, including Mauritius, utilize agricultural residues such as sugarcane bagasse for electricity generation, West African nations remain underdeveloped in this area. This study explores the potential of using alternative crop residues to alleviate energy stress and poverty in the region. Given the complexities of factors such as availability, moisture content, and energy content in crop selection, multicriteria decision analysis (MCDA) was employed to identify the most suitable crop residues for bioenergy production in West Africa. Expert consultations were conducted to define assessment criteria and evaluate various residues, including straws, peels, husks and shells, fibers, and stalks. The findings indicate that straw residues, particularly from cereals, are the most suitable for energy production, followed by husks and shells, stalks, fibers, and peels. The study estimates that West Africa could annually harvest approximately 402 million metric tons (Mt) of biomass, with an energy content of 6,960 Petajoules (PJ). Key crops such as cassava, maize, rice, and sorghum contribute significantly to this biomass potential, with cassava accounting for 35% of the total energy. Nigeria and Ghana emerge as the leading countries in terms of energy potential. The techno-economic assessment for 2021 estimates that 614 PJ, equivalent to 170 Terawatt hours (TWh), could be realized. With total energy consumption in West Africa reaching 3.05 EJ (3050 PJ) in 2022, agricultural residues alone could meet approximately 20.13% of the region's total energy demand. This research underscores the importance of strategic crop residue selection and biomass utilization as a key driver for sustainable energy production, offering a viable solution to energy poverty and fostering the adoption of renewable energy in West Africa.

Postoperatively, the EZE/ATZ group rats received a combination of EZE (10 mg/kg/d) and ATZ (20 mg/kg/d) for 4 weeks, after which they were sacrificed. Oil Red O staining was used to assess FI in the supraspinatus muscle. The expression of biomarkers related to muscle atrophy and FI was measured using quantitative real-time polymerase chain reaction. For the qualitative and quantitative analysis of FI-related biomarkers, immunohistochemical staining was performed. Biomechanical and histological analyses were performed to evaluate the quality of BTI healing after RC repair. Results: The EZE/ATZ group showed significantly lower FI compared with the control group (P < .001) and significantly downregulated expression of gene markers related to muscle atrophy and FI. On histological analysis, the EZE/ATZ group exhibited increased collagen type I contents, consistent collagen arrangement (P = .005), and significantly higher collagen density (P = .003) compared with the control group. Biomechanical analysis of the BTI healing revealed that the EZE/ATZ group had significantly increased ultimate strength (P = .006) compared with the control group. Conclusion: Systemic EZE/ATZ administration suppressed supraspinatus FI by downregulating muscle atrophy-related and FI-related genes after RC repair. Additionally, EZE/ATZ use improved collagen biosynthesis, density, and arrangement at the BTI and significantly increased tensile strength. Clinical Relevance: The results of the current study strongly advocate the use of EZE/ATZ to improve shoulder function and tendon healing after RC repair.

Article Overexpression of Syndecan-4 inhibits myogenesis by regulating the expression of myogenic regulatory factors Syndecan-4, a type of heparan sulfate proteoglycan, plays an important role in muscle development, regeneration, and maintenance. Although the important effects of Syndecan-4 on the regulation of myogenesis in mice, turkeys, and bovines have been consistently reported, the molecular mechanisms of Syndecan-4 in myogenesis are not well understood. In this study, the role of Syndecan-4 in regulating myogenesis was investigated in quail myoblast (QM7) cells, which constituting a quail myogenic cell line. Overexpression of Syndecan-4 inhibited myogenesis, resulting in reduced myoblast fusion and shorter myotubes than in the control group. Therefore, the cells overexpressing Syndecan-4 showed a smaller total myotube area than did the control cells. Furthermore, these cells had lesser myosin heavy chain proteins, suggesting that muscle differentiation is inhibited by Syndecan-4. To investigate the inhibitory effect of Syndecan-4 on myogenic differentiation, the mRNA expression levels in several genes known to regulate myoblast proliferation and differentiation were compared. Myogenic regulatory factors, including myogenic factor 5, myogenic differentiation 1, and myogenin, showed significantly different expressions between the groups during myogenesis. Myostatin, a negative regulator of muscle growth, showed significantly higher expression on day 4 in cells overexpressing Syndecan-4. In conclusion, Syndecan-4 could delay and inhibit muscle differentiation by regulating the expression levels of myogenic factors and muscle growth regulator in quail myocytes. This study provides valuable information regarding the role of Syndecan-4 in myogenesis, which may aid in improving the production of poultry meat.

Article Regulation of tick attachment and rapid engorgement via dopamine receptors in the Asian longhorned tick Haemaphysalis longicornis Dopamine plays multifaceted roles in the physiology of insects and ticks, acting as a key neurotransmitter and modulator of various biological processes. In ticks, it plays a particularly important role in regulating salivary gland function, which is essential for successful tick feeding on hosts. Salivary secretion in ticks is orchestrated by the collection of saliva in the acinar lumen mediated by the dopamine receptor (D1) and the expulsion of collected saliva into the salivary duct mediated by the invertebrate specific D1-like dopamine receptor (InvD1L). However, the function of dopamine receptors in different feeding stages and other tissues remains unclear. In this study, D1 and InvD1L of Haemaphysalis longicornis (Haelo-D1 and Haelo-InvD1L, respectively) were found to be involved in tick attachment and the rapid phase of blood feeding. Both receptors were identified and profiled in the synganglion, salivary glands, and midgut of H. longicornis females across different feeding stages. Functional analyses revealed that both receptors were activated by dopamine in a concentration-dependent manner with distinct sensitivities. RNA interference (RNAi) targeting these receptors significantly reduced dopaminemediated salivation and delayed tick attachment and blood feeding. Furthermore, RNAi prolonged rapid engorgement phases and reduced the final body weight of replete ticks. These results highlight the crucial roles of D1 and InvD1L in regulating salivary secretion in ixodid ticks and facilitating their attachment and rapid engorgement, thereby offering potential targets for novel tick control strategies aimed at disrupting feeding and reducing pathogen transmission.

Article The role of urban forests in mitigation of particulate air pollution: Evidence from ground observations in South Korea The effects of forests in mitigating urban air pollution have not been fully evaluated due to limited observational data. This study assesses the role of urban forests in reducing particulate matter (PM) using data from the recently installed ground PM observation network across South Korean forests, known as the Asian Initiative for Clean Air Networks (AICAN). Results show that urban forests are more effective at reducing coarse PM (with PM decrease efficiencies of 4.5 % to 24.4 % for PM2.5-10) than fine PM (1.5 % to 11.4 % for PM0.25-1.0), particularly in summer due to increased biomass growth. The diminished removal effects observed for fine PM may result from elevated physiological activities within forests, which can enhance the accumulation of fine PM. Buffering forests, planted as belts between pollution sources and residential areas, effectively mitigate PM pollution only when sufficiently wide (at least 200 m) and aligned with the prevailing wind direction. Tower measurements reveal PM deposition onto the forest canopy, while fine PM increases through turbulent diffusion under the canopy. This study underscores the importance of urban planning and reforestation strategies in reducing PM levels and highlights the significant role of urban forests in mitigating air pollution.

Article Assessment of forest fire vulnerability prediction in Indonesia: Seasonal variability analysis using machine learning techniques Forest fires significantly threaten Indonesia's tropical forests, driven by complex interactions between human activity, environmental conditions and climate variability. This research aims to identify and analyze the factors influencing forest fires in Kalimantan, Sumatra, and Papua during the rainy, dry and all-season conditions using machine learning techniques and create vulnerability prediction maps and categorize risk zones. Eight years (2015-2022) of forest fire data were combined with 15 forest fire susceptible factors that consider of human, environmental, meteorological, and land use/land cover conditioning factors. Random forest (RF) and eXtreme Gradient Boosting (XGB) machine learning models were used to train and validate the dataset through hyperparameter tuning and 10-fold cross-validation for accuracy assessment. The XGB model was selected as the best performer based on accuracy, recall, and F1-score and was used to generate probability values. The evaluation showed that the accuracies and AUC values for the nine models were greater than 0.7, with AUC values ranging from 0.71 to 0.95, indicating good performance. Papua had the highest accuracy, with 90.5%, 91.6%, and 92.5% for all, rainy, and dry seasons, respectively. Population density, elevation, precipitation, soil moisture, NDMI, NDVI, distance from roads and settlements, land surface temperature and peatlands are the key contributing factors of forest fire occurrences. Vulnerability maps categorized into five risk zones, identifying high-risk areas that aligned with observed fire occurrences. This research highlighted the diverse characteristics of factors that determine forest fires and examined their impact on fire occurrences. The findings provide actionable insights for targeted fire management strategies, though future research should incorporate additional variables to improve predictive accuracy and address long-term environmental changes.
