Published: January 2025

Indwelling medical devices, such as urinary catheters, often experience bacterial colonization, forming biofilms that resist antibiotics and the host’s immune defenses through quorum sensing (QS), a chemical communication system. This study explores the development of antimicrobial coatings by immobilizing acylase, a quorum-quenching enzyme, on sandblasted polydimethylsiloxane (PDMS) surfaces. PDMS, commonly used in medical devices, was sandblasted to increase its surface roughness, enhancing acylase attachment. FTIR analysis confirmed that acylase retained its three-dimensional structure upon immobilization, preserving its enzymatic activity. The antibacterial efficacy of the coatings was tested against Pseudomonas aeruginosa (P. aeruginosa) (a common biofilm-forming pathogen), Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli). The results showed that sandblasted PDMS surfaces had improved bacterial adhesion due to increased focal adhesion points, but acylase-functionalized surfaces had significantly reduced bacterial attachment and biofilm formation. Notably, the coatings inhibited P. aeruginosa growth by 40% under static conditions, demonstrating the potential of acylase-functionalized PDMS for medical applications. This approach offers a promising strategy for creating antimicrobial surfaces that prevent biofilm-related infections in urinary catheters and other medical devices. The findings highlight the dual role of surface roughness in enhancing enzyme attachment while reducing bacterial adhesion through effective QS inhibition.

Published: January 2025

Graphene’s incorporation into polymers has enabled the development of advanced polymer/graphene nanocomposites with superior properties. This study focuses on the use of a microcellular foamed polystyrene (PS)/graphene (GP) nanocomposite (3 wt%) for nickel (II) ion removal from aqueous solutions. Adsorption behavior was evaluated through FTIR, TEM, SEM, TGA, and XRD analyses. Key factors, including initial ion concentration, pH, temperature, and sorbent dosage, were examined. Results showed optimal nickel removal at specific pH levels with removal efficiency decreasing from 91 to 80% as Ni (II) concentrations increased from 10 to 100 mg/L. The adsorption capacity improved from 11 to 130 mg/g. Equilibrium data aligned with Langmuir and Freundlich isotherm models, while adsorption kinetics followed a second-order kinetic model. These findings highlight the potential of PS/GP nanocomposites for nickel ion removal, offering a promising solution for small-scale industrial applications.

Published: January 2025

The substantial waste generated during the processing of hides and skins as well as at other stages of manufacturing is a recurring issue in the leather industry that this article attempts to address. To investigate the mechanical and thermal characteristics of the resultant composites, this study suggests using leather waste from the bovine leather industry, analyzes the tanning process, and assesses the viability of mixing this waste with natural rubber (TSR-20). Without the inclusion of leather waste, the resulting composites had exceptional tensile strength, surpassing 100% of rubber’s strength. The effective interaction of the recycled leather particles with the natural rubber matrix was evidenced using the Lorentz–Park equation. This better performance points to a competitive relationship between rubber and leather waste. The samples’ density was 10% greater than that of polybutadiene elastomers and 10% greater than that of natural leather, while the hardness was comparable to that of PVC, which is frequently utilized in the design of general-purpose soles. This suggests that waste from the leather industry can be efficiently utilized in sustainable applications, particularly in the production of leather goods and shoes, helping to valorize waste that is typically discarded. Furthermore, by encouraging the use of recycled resources in the creation of new compounds, this plan provides the rubber sector with a sustainable option. To optimize this proposal, perhaps will be necessary to identify different vulcanization systems to improve the physical mechanical properties and other uses derived from the optimizations realized. This composite can be applied in the fashion industry in order to develop new trends around the application of waste and residues for a natural design line. Through the research process, it was possible to integrate the residues into the natural rubber matrix, as evidenced in the characterization process.

Published: January 2025

Bone tissue engineering aims to develop biomaterials that are capable of effectively repairing and regenerating damaged bone tissue. Among the various polymers used in this field, polycaprolactone (PCL) is one of the most widely utilized. As a biocompatible polymer, PCL is easy to fabricate, cost-effective, and offers consistent quality control, making it a popular choice for biomedical applications. However, PCL lacks inherent antibacterial properties, making it susceptible to bacterial adhesion and biofilm formation, which can lead to implant failure. To address this issue, this study aims to enhance the antibacterial properties of PCL by incorporating calcium phosphate composite (PCL_CaP) nanostructures onto its surface via hydrothermal synthesis. The resulting “PCL_CaP” nanostructured surfaces exhibited improved wettability and demonstrated mechano-bactericidal potential against Escherichia coli and Bacillus subtilis. The flake-like morphology of the fabricated CaP nanostructures effectively disrupted bacteria membranes, inhibiting bacterial growth. Furthermore, the “PCL_CaP” surfaces supported the adhesion, proliferation, and differentiation of pre-osteoblasts, indicating their potential for bone tissue engineering applications. This study demonstrates the promise of calcium phosphate composite nanostructures as an effective antibacterial coating for implants and medical devices, with further research required to evaluate their long-term stability and in vivo performance.

Published: January 2025

Crystallization-induced blockages in tunnel drainage systems pose significant challenges to their functionality and longevity. To address this issue, this study proposes a novel adaptive drainage pipe designed to prevent crystallization. By constructing an indoor experimental model for anti-crystallization tests, combined with scanning electron microscopy (SEM) and molecular dynamics simulations, this study investigates the mechanism and effectiveness of the proposed system. The findings reveal that flexible PVC pipes in dynamic flow and expansion states significantly reduce crystallization compared to conventional PVC pipes. Among tested materials, EVA and TPU demonstrate superior crystallization resistance, with EVA exhibiting the lowest crystallization accumulation (7.13 g/m). Molecular dynamics simulations further elucidated the influence of material properties on the diffusion coefficient and binding energy of calcium carbonate crystals, with EVA showing the lowest binding energy with calcium carbonate at 135.11 kcal/mol, ultimately confirming EVA as the optimal material for crystallization prevention. These results offer new strategies and valuable references for managing crystallization in tunnel drainage systems.

Published: January 2025

Green chemistry seeks to find alternative synthesis routes that are less harsh to living organisms and the environment. In this communication, a microwave-assisted hydrothermal technique and a thermal annealing method were used in the reduction of graphene oxide (GO) to make reduced GO (rGO). Graphite powder was oxidised using the Improved Hummers’ method, exfoliated, and freeze-dried. Thereafter, an aqueous suspension of GO was reduced under microwave (MW) irradiation for 10 min at 600 W with and without the help of a reducing agent (hydrazine hydrate). Thermal annealing reduction was also conducted under a nitrogen atmosphere at 300 °C for 1 h. Prepared samples were analysed using Raman laser spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), the Brunauer–Emmett–Teller (BET) method, and X-ray photoelectron spectroscopy (XPS). A successful reduction in the GO functional groups between the sheets was established using XRD. In the Raman analysis, the ratio of the intensity of the D and G band (ID/IG) in graphene sheets assisted in assessing the quality of the graphene films. An estimation of the number of structural defects was calculated using the ID/IG ratio. The Raman analysis showed an increase in the ID/IG ratio after both oxidation and reduction processes. The defect densities of both MW-treated samples were comparable while an increased defect density was evident in the thermally annealed sample. TEM micrographs confirmed the sheet-like morphology of the samples. The rGO sheets obtained from the MW-treated method appeared to be smaller when compared to the rGO ones obtained by thermal treatment. It was also evident from XRD analysis that thermal treatment promoted the coalition of graphitic layers, such that the estimated number of layers was larger than that of GO. The elemental analysis showed that the C/O ratio of GO increased from 2 to 7.8 after MW hydrazine reduction.

Published: January 2025

The antifungal efficacy of coffee residue extract (CRE) and chitosan nanoparticles (CNPs) alone and in combination (CNPs-CRE) against the growth of Rhizopus stolonifer was assessed. Two nanostructured edible coatings (ECs), one consisting of chitosan nanoparticles (CCNP) and another consisting of coffee residue extract encapsulated in chitosan nanoparticles (CCNP-CRE), were elaborated, characterized, and applied on inoculated Naples tomatoes to evaluate their fungicidal activity and their effect on fruit quality. The tests consisted of evaluating physicochemical variables in tomato previously sprayed with CCNP and CCNP-CRE for 30 days preharvest and 14 days at 10 °C postharvest. CNPs with a particle size of 2.4 ± 0.24 nm with a Z potential of −1.62 mV were observed, while CNPs-CRE showed a size of 3.9 ± 0.55 nm with a Z potential of −0.89 mV. The FTIR spectrum showed the integration of CRE into the CCNP-CRE. A synergistic effect between CNPs and 1% CRE was observed, obtaining the greatest inhibition of mycelial growth (43%). In the preharvest trials, both ECs showed differences with respect to the control in the variables of color, total carotenoids and ethylene. In the postharvest test, they showed differences in color and CO2 production. The severity of the infection decreased by 33% in tomatoes with coatings. The ECs evaluated represent a emergent technological advancement in the conservation of the tomato.

Authors: Chaher Nour El Houda , Nassour Abdallah , Nelles Michael
Published: January 2025

The current research work emphasizes the urgent need for a paradigm shift in Mediterranean tourism, advocating for the adoption of a comprehensive framework centered on sustainability in Tunisia. The establishment of an Inter-Ministerial Task Force is proposed to facilitate collaboration across governmental sectors, thereby enhancing governance and addressing the complexities of waste management within the tourism industry. Results reveal significant waste management inefficiencies and underscore the potential of integrated approaches that can lead to substantial environmental improvements. By fostering inter-ministerial collaboration, a strategic roadmap is provided that promotes effective resource recovery and sustainable waste management practices. Furthermore, the integration of the informal sector, exemplified by local recyclers, into formal waste management systems is anticipated to enhance social equity and bolster environmental stewardship. A comprehensive SWOT analysis identifies Tunisia’s intrinsic strengths, including its rich cultural heritage and significant eco-tourism potential, while simultaneously exposing shortcomings such as fragmented governance structures and insufficient infrastructure. It is posited that the creation of a centralized coordination body, coupled with the enhancement of public–private partnerships, could catalyze innovation in sustainable tourism practices, leading to increased investment opportunities and the successful implementation of circular economy principles. Drawing inspiration from Spain’s successful circular economy model, actionable recommendations for policymakers are offered, including the introduction of eco-certification programs aimed at incentivizing environmentally responsible practices within the tourism sector. Ultimately, the proposed framework aspires to position Tunisia as a regional leader in sustainable tourism, delivering long-term benefits to local communities through enhanced environmental protection and economic resilience.
Displacing the Christian Theodicy of Hell: Yi Kwangsu’s Search for the Willful Individual in Colonial Modernity
Authors: Kwak Jun-Hyeok , Huang Mengxiao
Published: January 2025

This article aims to offer Yi Kwangsu’s The Heartless (Mujŏng, 1917), the first modern Korean novel, as an emblem of hybrid religiosity in colonial modernity that sheds light on an ambivalent alterity in the problem of hell in non-Western cultures. To the extent that the problem of hell in Christianity pertains to the question of why God allows evil to exist eternally, God’s omnipotent authority with justice and fairness beyond the grave is placed at the center of the inquiry into the ultimate standard of moral goodness the religious feasibility of which justifies the existence of sinners suffering eternal damnation in hell. But the co-existence of the omnipotent God and unrepentant sinners is not always questioned in the religiosity of hell in non-Western cultures. The Christian imaginary of hell in non-Western cultures often demarcates the question of God’s sovereignty from the sufferings of sinners in the problem of hell. Based on these observations, this article will investigate Yi’s narratives of hell in The Heartless, which are associated with Christianity but intertwined with his ethical demands for shaping a new individuality beyond the traditional hybrid religiosity of hell. Specifically, first, we will show that Yi’s Christian imaginary of hell is reformulated through the traditional imaginaries of hell in which, regardless of the existence of God’s sovereignty over the created order, the sufferings of sinners in hell function to secure social norms and orders. In doing so, we claim that the Christian imaginary of hell in The Heartless is relegated to a rhetorical means to beget the need for the self-awakening of the inner-self through which individual desires can be freed from the influences of Confucian morality as well as Christian theodicy. Second, in comparison with Lu Xun’s sympathetic relocation of Christian spirituality within the traditional Chinese imaginaries of hell in his longing for modern subjectivity, we explore Yi’s hybrid religiosity within colonial modernity, the vitality of which cannot be confined within the simple dichotomy between Western and non-Western cultures. At this juncture, the upshot of Yi’s hybrid religiosity within colonial modernity is that the theodicy of hell in Christianity can be displaced and thereby disenfranchised from the centrality of the search for a new individuality.
Inclined Aerial Image and Satellite Image Matching Based on Edge Curve Direction Angle Features
Authors: Wang Hao , Liu Chongyang , Ding Yalin , Sun Chao , Yuan Guoqin , Zhang Hongwen
Published: January 2025

Optical remote sensing images are easily affected by atmospheric absorption and scattering, and the low contrast and low signal-to-noise ratio (SNR) of aerial images as well as the different sensors of aerial and satellite images bring a great challenge to image matching. A tilted aerial image and satellite image matching algorithm based on edge curve direction angle features (ECDAF) is proposed, which accomplishes image matching by extracting the edge features of the images and establishing the curve direction angle feature descriptors. First, tilt and resolution transforms are performed on the satellite image, and edge detection and contour extraction are performed on the aerial image and transformed satellite image to make preparations for image matching. Then, corner points are detected and feature descriptors are constructed based on the edge curve direction angle. Finally, the integrated matching similarity is computed to realize aerial–satellite image matching. Experiments run on a variety of remote sensing datasets including forests, hills, farmland, and lake scenes demonstrate that the effectiveness of the proposed algorithm shows a great improvement over existing state-of-the-art algorithms.

Published: January 2025

The time period around the Noachian–Hesperian boundary, 3.7 billionyears ago, was an epoch when great geodynamical and environmental changes occurred on Mars. Currently available remote sensing data are crucial for understanding the Martian heat loss pattern and its global thermal state in this transitional period. We here derive surface heat flows in specific locations based on the estimations of the depth of five large thrust faults in order to constrain both surface and mantle heat flows. Then, we use heat-producing element (HPE) abundances mapped from orbital measurements by the Gamma-Ray Spectrometer (GRS) onboard the Mars Odyssey 2001 spacecraft and geographical crustal thickness variations to produce a global model for the surface heat flow. The heat loss contribution of large mantle plumes beneath the Tharsis and Elysium magmatic provinces is also considered in our final model. We thus obtain a map of the heat flow variation across the Martian surface at the Noachian–Hesperian boundary. Our model also predicts an average heat flow between 32 and 50 mW m−2, which implies that the heat loss of Mars at that time was lower than the total radioactive heat production of the planet, which has profound implications for the thermal history of Mars.

Published: January 2025

Mastoidectomy is critical in acoustic neuroma surgery, where precise planning of the bone milling area is essential for surgical navigation. The complexity of representing the irregular volumetric area and the presence of high-risk structures (e.g., blood vessels and nerves) complicate this task. In order to determine the bone area to mill using preoperative CT images automatically, we propose an automated planning method using evolutionary multi-objective optimization for safer and more efficient milling plans. High-resolution segmentation of the adjacent risk structures is performed on preoperative CT images with a template-based approach. The maximum milling area is defined based on constraints from the risk structures and tool dimensions. Deformation fields are used to simplify the volumetric area into limited continuous parameters suitable for optimization. Finally, a multi-objective optimization algorithm is used to achieve a Pareto-optimal design. Compared with manual planning on six volumes, our method reduced the potential damage to the scala vestibuli by 29.8%, improved the milling boundary smoothness by 78.3%, and increased target accessibility by 26.4%. Assessment by surgeons confirmed the clinical feasibility of the generated plans. In summary, this study presents a parameterization approach to irregular volumetric regions, enabling automated milling area planning through optimization techniques that ensure safety and feasibility. This method is also adaptable to various volumetric planning scenarios.
Evaluating the Reliability and Consistency of Treadmill Gait Analysis Using an RGB-D Camera: Effects of Assistance and No Assistance
Authors: Hosoi Yuichiro , Sato Takahiko , Nagano Akinori
Published: January 2025

This study aimed to assess the intraday reliability of markerless gait analysis using an RGB-D camera versus a traditional three-dimensional motion analysis (3DMA) system with and without a simulated walking assistant. Gait assessments were conducted on 20 healthy adults walking on a treadmill with a focus on spatiotemporal parameters gathered using the RGB-D camera and 3DMA system. The intraday reliability of the RGB-D camera was evaluated using intraclass correlation coefficients (ICC 1, 1), while its consistency with the 3DMA system was determined using ICC (2, 1). The results demonstrated that the RGB-D camera provided high intraday reliability and showed strong consistency with 3DMA measurements regardless of the presence of an assistant. The Bland–Atman analysis indicated no significant systematic bias, with the minimum detectable change remaining within acceptable clinical ranges. These findings highlight the potential of the RGB-D camera for reliable markerless gait analysis in clinical environments in which walking assistance may be needed, thereby expanding its applicability in patients with various impairment degrees. Future research should validate these results in patient populations and explore their utility for measuring kinematic parameters.

Authors: Zhang Lei , Ma Xiaodong , Xu Weishuai , Wan Xiang , Chen Qiyun
Published: January 2025

Mesoscale eddies are pivotal oceanographic phenomena affecting marine environments. Accurate and stable identification of these eddies is essential for advancing research on their dynamics and effects. Current methods primarily focus on identifying Cyclonic and Anticyclonic eddies (CE, AE), with anomalous eddy identification often requiring secondary analyses of sea surface height anomalies and eddy center properties, leading to segmented data interpretations. This study introduces a deep learning model integrating multi-source fusion data with a Squeeze-and-Excitation (SE) attention mechanism to enhance the identification accuracy for both normal and anomalous eddies. Comparative ablation experiments validate the model’s effectiveness, demonstrating its potential for more nuanced, multi-source, and multi-class mesoscale eddy identification. This approach offers a promising framework for advancing mesoscale eddy identification through deep learning.
The Documentation Status Continuum and the Impact of Categories on Healthcare Stratification
Authors: Joseph Tiffany Denise
Published: January 2025

Public discourse on immigration and social services access has been contentious in immigrant-receiving countries. Scholars have examined immigrants’ marginalization as a form of civic stratification, where boundaries based on documentation status affect immigrants’ experiences and benefits granted by the state. This scholarship lacks a framework outlining existing documentation status categories and does not fully answer three research questions I pose in this article: (1) what is the alignment of documentation status categories relative to each other, (2) how does policy (re)configure those categories over time, and (3) how have documentation status categories shaped access to health care in the United States? This article answers those questions and argues that the documentation status continuum (DSC) framework fills these gaps. In the DSC, undocumented immigrants are at one end and citizens are at the other, with many documentation statuses in between. Public policy creates these statuses and generates stratification through allocating benefits based on one’s DSC position. Policy also shapes movement along the continuum, which shapes benefits eligibility. Using the 2006 Massachusetts Health Reform and national 2010 Affordable Care Act (ACA) Reform as policy examples and interviews conducted with 207 immigrants, healthcare professionals, and immigrant organization employees in Boston, this article demonstrates how healthcare access is stratified along the DSC between citizens and noncitizens. This has implications for various outcomes that social scientists examine amid increasing anti-immigrant sentiment in the US and beyond.

Published: January 2025

Physical inactivity is a major global public health concern, and table tennis offers a low-impact, engaging way to promote physical activity across various age groups. However, many beginners struggle to maintain effective participation due to their lower skill levels. Therefore, the development and reinforcement of stable grip techniques is crucial because it will help beginners achieve sustainable improvements in performance. This will provide additional opportunities to increase physical activity, and therefore overall health, across all age groups. Thus, in this study, we investigate the effects of a prototype table tennis handle on the racket angle and performance of beginners. The prototype handle features a 20° tilt to assist the player in maintaining a stable topspin forehand grip during play. The participants were randomized into three groups, Groups A, B, and C, which used the prototype handle, standard handle, and practiced with the prototype but performed tests with the standard handle, respectively. The participants executed topspin forehand strokes in approximately 30 min of practice, and data on racket angles, swing mechanics, success rates, and ball landing positions were collected. The results showed that Group A exhibited a larger racket open angle and a smaller racket face Angle than the other groups. However, the groups showed no significant differences in hit positions or overall success rates. Our results suggest that although the prototype handle can influence racket angles and some performance aspects, individual differences and swing mechanics should be considered.
Moral Imperative or Economic Necessity? The Role of Institutional Investors in the Corporate Social Responsibility—Financial Performance Relationship
Authors: Yeon Jihwan , Song Hyoung Ju , Kim Bora
Published: January 2025

This study examines how institutional ownership concentration, quantified by the Herfindahl-Hirschman Index (HHI), influences the financial consequences of CSR initiatives within the U.S. restaurant industry. This study distinguishes between CSR activities that are integral to core operations (operation-related CSR) and those that are not (non-operation-related CSR), analyzing their impacts on both market-based (ROA) and accounting-based performance (Tobin’s q) measures. Employing panel regression analysis, findings reveal that higher institutional ownership concentration enhances the alignment of operation-related CSR with improved financial performance. Conversely, the institutional ownership concentration does not significantly moderate the impact of non-operation-related CSR on both performance measures. Given the restaurant industry’s high consumer visibility and operational reliance on social and environmental factors, this study fills gaps in CSR literature by offering insights for aligning CSR strategies with institutional owners’ expectations. The results provide actionable guidance for policymakers and industry practitioners to optimize organizational outcomes from CSR activities.

Published: January 2025

Entry into the profession of archaeology generally requires the completion of an archaeological field school, which teaches proper field, laboratory, and curation methodologies. Archaeology as a discipline has been making strides towards integrating cross-disciplinary methods to increase the depth and breadth of the subject and enhancing inclusivity. These efforts have been mirrored in the approaches of some archaeological field schools, but not necessarily in a systematic fashion. This paper presents a cohesive framework for an archaeological field school that integrates cross-disciplinary training and inclusivity by model of the United Nations Sustainable Development Goals (UN SDGs), specifically SDGs 11: Sustainable Cities and Communities, 13: Climate Action, 4: Quality Education, and 11: Reduced Inequalities. Both how the framework could be implemented across a variety of archaeology field schools and how it has been implemented in the Florida Public Archaeology Network (FPAN) field school held in Jupiter, Florida, are discussed. Furthermore, we present preliminary survey data from field school participants to demonstrate how this field school supports SDG 10: Reduced Inequalities.

Published: January 2025

Optimizing offshore wind power technology and reducing the levelized cost of electricity throughout the lifecycle are key measures for the large-scale development of offshore wind power, contributing significantly to the transition toward sustainable energy systems. However, compared to onshore wind power, the internal flow dynamics of offshore wind farms are more complex, which poses challenges for operation and maintenance. Therefore, there is an urgent need for updated, smarter, more efficient, and economic offshore intelligent operation control technologies to facilitate the large-scale development and utilization of offshore wind power. This paper approaches the topic from two perspectives, offshore wind turbines and offshore wind farms, introducing popular research directions and technical bottlenecks in these two related fields. This includes offshore wind turbine capacity development and fundamental technologies, offshore wind power forecasting technology, and offshore wind power operation and control technology, offshore intelligent operation and maintenance technology, as well as offshore wind power and integrated marine area utilization technology. Firstly, the challenges faced by the intensive development of offshore wind resources and operational environments are analyzed. Secondly, the challenges encountered in the aforementioned technological areas and their potential solutions are summarized. Finally, a systematic reflection and outlook on the large-scale development of offshore wind power are provided, reinforcing its critical role in achieving global sustainability goals.
Analysis of Urban Rail Public Transport Space Congestion Using Graph Fourier Transform Theory: A Focus on Seoul
Authors: Li Cheng-Xi , Yoon Cheol-Jae
Published: January 2025

Urban transportation efficiency is critical in densely populated cities, such as Seoul, South Korea, where subway transfer stations are vital. This study investigates the spatial efficiency and passenger flow dynamics of multilayered transfer stations, using triangular Fourier transform as the primary analytical method. The research incorporates principal component analysis (PCA) and K-means clustering to classify stations based on structural characteristics and congestion patterns. Data derived from transportation card usage during peak hours and architectural layouts were analysed to identify critical bottlenecks. The results highlighted notable inefficiencies in transfer times and congestion. For example, the analysis revealed that optimising transfer corridors at Seoul Station could reduce average transfer times by over 10 min. Dongdaemun History & Culture Park Station would benefit from ground-level pathways to address inefficiencies caused by its extensive underground network. Sindorim Station’s reorganisation of above-ground and underground connectivity was found to enhance passenger flow. By introducing the concept of the ‘entry baseline for passenger flow in public buildings’, this study offers a novel framework for evaluating and improving urban transit infrastructure. The findings provide actionable insights into transfer station design, supporting strategies for addressing the challenges of urban mobility in megacities while contributing to transit-oriented development.

Authors: Shi Xiaohong , Zailani Suhaiza
Published: January 2025

Amidst rapid technological progress and increasing regulatory demands, the Chinese video game industry has undergone rapid changes that have provided a fruitful context for examining corporate competencies. Drawing on the Resource-Based View (RBV) and Dynamic Capability View (DCV) theories, this study investigates how firm capabilities (FC) and firm resources (FR) contribute to value creation (VC), which subsequently influences firm performance (FP) and sustainable competitive advantage (SCA). A quantitative research approach was employed, utilizing the data collected from a questionnaire survey of 241 video game firms. The data analysis was conducted using SmartPLS4 software, revealing that FC/FR has a significant effect on VC, which, in turn, mediates the relationship between FC/FR and FP. This study identifies three dimensions of VC—customer value (CV), employee value (EV), and shareholder value (SV)—with EV showing stronger mediating effects than CV and SV. It then uses the BSC framework to assess FP’s intermediary role in bridging VC with SCA through the integration of both financial and non-financial performance indicators relevant to the dynamic video game industry. These results have strong theoretical and practical implications, offering valuable guidance for fostering sustainable development. Specifically, they provide actionable insights for managers to enhance value creation and firm performance while also offering policy recommendations to support regulatory compliance and promote sustainable practices in China’s dynamic video game industry.
Low-Frequency Longitudinal Vibrations of a Fluid-Loaded Elastic Layer
Authors: Shamsi Sheeru , Prikazchikova Ludmila
Published: January 2025

This paper concerns the low-frequency symmetric (extensional) motions of a thin elastic layer submerged in a fluid. This problem is less investigated than that for antisymmetric motion corresponding to bending vibrations, partly because the classical theory for thin-plate extension is not oriented to model the transverse compression of the plate caused by the pressure of the fluid. It is also worth noting that, in contrast to a fluid-borne bending wave, the extensional wave radiates into the fluid, resulting in complex-valued terms in the associated dispersion relation. In this paper, we derive a refined asymptotic formulation for symmetric motion starting from the 2D plane strain problem regarding fluid–structure interaction. The obtained results have the potential to be implemented for interpreting numerical and experimental data for a variety of modern engineering setups.
A Systematic Method Combining Rotated Convolution and State Space Augmented Transformer for Digitizing and Classifying Paper ECGs
Authors: Wang Xiang , Yang Jie
Published: January 2025

Billions of paper Electrocardiograms (ECGs) are recorded annually worldwide, particularly in the Global South. Manual review of this massive dataset is time-consuming and inefficient. Accurate digital reconstruction of these records is essential for efficient cardiac disease diagnosis. This paper proposes a systematic framework for digitizing paper ECGs with 12 symmetrically distributed leads and identifying abnormal samples. This method consists of three main components. First, we introduce an adaptive rotated convolution network to detect the positions of lead waveforms. By exploiting the symmetric distribution of 12 leads, a novel loss is proposed to improve the detection model’s performance. Second, image processing techniques, including denoising and connected component analysis, are employed to digitize ECG waveforms. Finally, we propose a transformer-based classification method combined with a state space model. Our process is evaluated on a large synthetic dataset, including ECG images characterized by rotations, noise, and creases. The results demonstrate that the proposed detection method can effectively reconstruct paper ECGs, achieving an 11% improvement in SNR compared to the baseline. Moreover, our classification model exhibits slightly higher performance than other counterparts. The proposed approach offers a promising solution for the automated analysis of paper ECGs, supporting clinical decision-making.

Published: January 2025

Linear antenna arrays exhibit radiation patterns that are restricted to a half-space and feature axial radiation, which can be a significant drawback for applications that require omnidirectional coverage. To address this limitation, the synthesis method utilizing the Taguchi approach, originally designed for linear arrays, can be effectively extended to two-dimensional or planar antenna arrays. In the context of a linear array, the synthesis process primarily involves determining the feeding law and/or the spatial distribution of the elements along a single axis. Conversely, for a planar array, the synthesis becomes more complex, as it requires the identification of the complex weighting of the feed and/or the spatial distribution of sources across a two-dimensional plane. This adaptation to planar arrays is facilitated by substituting the direction θ with the pair of directions (θ,ϕ), allowing for a more comprehensive coverage of the angular domain. This article focuses on exploring various configurations of planar arrays, aiming to enhance their performance. The primary objective of these configurations is often to minimize the levels of secondary lobes and/or array lobes while enabling a full sweep of the angular space. Secondary lobes can significantly impede system performance, particularly in multibeam applications, where they restrict the minimum distance for frequency channel reuse. This restriction is critical, as it affects the overall efficiency and effectiveness of communication systems that rely on precise beamforming and frequency allocation. By investigating alternative planar array designs and their synthesis methods, this research seeks to provide solutions that improve coverage, reduce interference from secondary lobes, and ultimately enhance the functionality of antennas in diverse applications, including telecommunications, radar systems, and wireless communication.

Background/Objectives: The aim was to investigate the association between variations in the dorsal pancreatic artery (DPA) and intrapancreatic arcade anatomy with Whipple procedure outcomes and postoperative complications. Methods: This retrospective study was conducted with 362 patients who underwent a Whipple procedure at the Department of Gastroenterological Surgery of Adana City Training and Research Hospital between January 2018 and April 2024. All data collected from medical records were compared and statistically analyzed according to the patients’ survival status and arcade subtypes. Results: After excluding cases that did not meet the study criteria, a total of 284 patients were included in the study. DPA was visualized in 55.98% (159/284) of patients, while the intrapancreatic arcade was observed in 25% (71/284). The most common origin of the DPA was the splenic artery in 69.2% (n = 110) of patients, followed by the superior mesenteric artery in 17.6% (n = 28). The frequency of intrapancreatic arcade anatomy variations was as follows: type 1: 28.2% (n = 20), type 2: 49.3% (n = 35) and type 3: 22.5% (n = 16). Arcade type 4 anatomy was not detected. Postoperative pancreatic fistula (POPF) complication was found to be statistically significantly higher in patients with type 3 anatomy (p = 0.042). The 90-day mortality and long-term mortality rates did not differ among the groups based on the variations in both DPA and intrapancreatic arcade anatomy types. Conclusions: Patients with intrapancreatic arcade type 3 anatomy had a higher risk of POPF complications. Determination of preoperative arcade type by computed tomography (CT) angiography may help to predict the risk of POPF.

Aflatoxin B1 (AFB1) contamination of food crops pose severe public health risks, particularly in decentralized agricultural systems common in low-resource settings. Effective monitoring tools are critical for mitigating exposure, but their adoption is limited by barriers such as cost, infrastructure, and technical expertise. The objectives of this study were: (1) to evaluate common AFB1 detection methods, including enzyme-linked immunosorbent assays (ELISA) and lateral-flow assays (LFA), validated via high-performance liquid chromatography (HPLC), focusing on their suitability for possible applications in decentralized, low-resource settings; and (2) to conduct a barriers-to-use assessment for commonly available AFB1 detection methods and their applicability in low-resource settings. Among four ELISA kits, the AgraQuant Aflatoxin B1 2/50 ELISA Kit demonstrated the highest accuracy and precision, reliably quantifying AFB1 in maize and tortillas across 5–150 ppb with minimal cross-reactivity. For LFA, a smartphone-based algorithm achieved a high presence/absence accuracy rate of 84% but struggled with concentration prediction. The barriers-to-use analysis highlighted the practicality of low-cost tools like moisture readers for field screening but underscored their qualitative limitations. Advanced methods like HPLC and LC-MS offer greater precision but remain impractical due to their high costs and infrastructure requirements, suggesting a potential role for adapted ELISA or LFA methods as confirmatory approaches. These findings support the development of multi-tiered frameworks integrating affordable field tools with regional or centralized confirmatory testing. Addressing systemic barriers through capacity building, partnerships, and improved logistics will enhance AFB1 monitoring in decentralized systems, protecting public health in vulnerable communities.

Accurate rapid diagnostic tests (RDTs) are needed to diagnose lymphatic filariasis (LF) in global elimination programmes. We evaluated the performance of the new STANDARD Q Filariasis Antigen Test (QFAT) against the Bioline Filariasis Test Strip (FTS) for detecting W. bancrofti antigen (Ag) in laboratory conditions, using serum (n = 195) and plasma (n = 189) from LF-endemic areas (Samoa, American Samoa and Myanmar) and Australian negative controls (n = 46). The prior Ag status of endemic samples (54.9% Ag-positive) was determined by rapid test (ICT or FTS) or Og4C3 ELISA. The proportion of samples testing positive at 10 min was similar for QFAT (44.8%) and FTS (41.3%). Concordance between tests was 93.5% (kappa 0.87, n = 417) at 10 min, and it increased to 98.8% (kappa 0.98) at 24 h. The sensitivities of QFAT and FTS at 10 min compared to the prior results were 92% (95% CI 88.0–96.0) and 86% (95% CI 80.0–90.0), respectively, and they increased to 97% and 99% at 24 h. Specificity was 98% for QFAT and 99% for FTS at 10 min. Both tests showed evidence of cross-reaction with Dirofilaria repens and Onchocerca lupi but not with Acanthochilonema reconditum or Cercopithifilaria bainae. Under laboratory conditions, QFAT is a suitable alternative RDT to FTS.
