Abstract Natural rubber (NR) foams are widely used. However, further studies are required for preparing eco-friendly NR foam and determining the optimum physical properties appropriate for application. This study aims to create an NR foam from rubber reinforced with sugarcane bagasse ash (SCBA) and sodium alginate. The results showed that the SCBA was primarily composed of silica or silicon dioxide (87.52% by weight) and carbon (11.41% by weight). This study investigated the influence of the amount of sodium alginate (0–5 phr) used in the NR foam formation. The addition of SCBA on the NR foam affected More > Graphic Abstract

Abstract Furfurylation, a renowned chemical modification technique, uses furfuryl alcohol to enhance the properties of wood. This technology can be further refined by incorporating renewable tannins, which promote cross-linking with furfuryl alcohol. This study investigates the effects of furfurylation and tannin-modified furfurylation on the physical and mechanical properties of tropical Gmelina wood (Gmelina arborea Roxb.). Experiments involved impregnating Gmelina wood with aqueous solutions of furfuryl alcohol (FA) at 40% and 70% concentrations, as well as FA-tannin combinations (FA 40%-TA and FA 70%-TA), followed by polymerization at 103°C. The results demonstrated that both FA and FA-tannin treatments significantly… More > Graphic Abstract

Abstract Physical layer authentication (PLA) in the context of the Internet of Things (IoT) has gained significant attention. Compared with traditional encryption and blockchain technologies, PLA provides a more computationally efficient alternative to exploiting the properties of the wireless medium itself. Some existing PLA solutions rely on static mechanisms, which are insufficient to address the authentication challenges in fifth generation (5G) and beyond wireless networks. Additionally, with the massive increase in mobile device access, the communication security of the IoT is vulnerable to spoofing attacks. To overcome the above challenges, this paper proposes a lightweight deep More >

Abstract Cyber-Physical Systems (CPS) represent an integration of computational and physical elements, revolutionizing industries by enabling real-time monitoring, control, and optimization. A complementary technology, Digital Twin (DT), acts as a virtual replica of physical assets or processes, facilitating better decision making through simulations and predictive analytics. CPS and DT underpin the evolution of Industry 4.0 by bridging the physical and digital domains. This survey explores their synergy, highlighting how DT enriches CPS with dynamic modeling, real-time data integration, and advanced simulation capabilities. The layered architecture of DTs within CPS is examined, showcasing the enabling technologies and… More >

Abstract Background: Adolescents face increasing academic and social pressures, which significantly impact their mental well-being and coping strategies. Physical activity (PA) has been recognized as crucial in promoting psychological resilience and social development. This study investigates the relationship between PA and adolescents’ coping styles, with a particular focus on the mediating roles of friendship quality and psychological resilience. By examining these associations, the study aims to provide insights into how PA contributes to adolescents’ ability to navigate challenges and develop adaptive coping mechanisms. Methods: This study employed a cross-sectional design and was conducted in Suzhou, Jiangsu… More >

Abstract Objectives: The current study aimed to perform a meta-analysis to comprehensively investigate effect of physical activity on cognitive function in people with Mild Cognitive Impairment. The findings of this study can offer an important basis for identifying the significance of physical activity as an important factor in designing and implementing strategies to enhance cognitive function in mild cognitive impairment. Methods: 21 articles were selected through academic databases (EBSCOhost, PubMed, ScienceDirect, Web of Science), and 20 Montreal Cognitive Assessment (MoCA) data and 15 Mini-Mental State Examination (MMSE) data were obtained. The study was conducted using the… More >

Abstract Background: This study evaluated physical fitness and mental health in young and elderly women 3 months after mild COVID-19 infection, and examined the impact of infection and age on long COVID occurrence and trajectory. Methods: There were 213 eligible female volunteers (107 young, 106 elderly) recruited approximately three months after the significant outbreak of COVID-19 in China. Participants completed a fitness test and mental health assessment using the Post-Traumatic Stress Disorder Self-Assessment Scale (PTSD) and the Pittsburgh Sleep Quality Inventory (PSQI).

Abstract The deep potential (DP) is an innovative approach based on deep learning that uses ab initio calculation data derived from density functional theory (DFT), to create high-accuracy potential functions for various materials. Platinum (Pt) is a rare metal with significant potential in energy and catalytic applications, However, there are challenges in accurately capturing its physical properties due to high experimental costs and the limitations of traditional empirical methods. This study employs deep learning methods to construct high-precision potential models for single-element systems of Pt and validates their predictive performance in complex environments. The newly developed DP… More >

Abstract Background: Taking actions to maintain a healthy lifestyle, including regular engagement in physical activity (PA) and reducing sedentary behavior (SB), may protect against the development of internalizing problems among healthy youth. However, it remains unclear whether such associations exist among youth with chronic pain who often report symptoms of depression and anxiety. To this end, we aimed to investigate the associations between independent and combined PA and/or SB patterns with indicators of internalizing problems in this vulnerable population. Methods: Data used in this cross-sectional study were retrieved from the U.S. National Survey of Children’s Health… More >

Abstract Background: Restrained eating, often motivated by the desire to control weight, is prevalent among young female college students and is considered a risk factor for eating disorders. Negative evaluation fear, exacerbated by social pressure, peer comparison, and academic stress, has been identified as a potential contributor to restrained eating behavior. However, research exploring the relationship between negative evaluation fear and restrained eating, particularly in the context of self-esteem and physical appearance perfectionism, remains limited. This study aims to investigate these relationships and design an intervention program to reduce restrained eating behaviors in female college students.… More >
