Abstract This study presents a numerical analysis of the steady-state solution for transient magnetohydrodynamic (MHD) dissipative and radiative fluid flow, incorporating an induced magnetic field (IMF) and considering a relatively high concentration of foreign mass (accounting for Soret and Dufour effects) over a vertically oriented semi-infinite plate. The governing equations were normalized using boundary layer (BL) approximations. The resulting nonlinear system of partial differential equations (PDEs) was discretized and solved using an efficient explicit finite difference method (FDM). Numerical simulations were conducted using MATLAB R2015a, and the developed numerical code was verified through comparison with another… More >

Abstract As the penetration rate of distributed energy increases, the transient power angle stability problem of the virtual synchronous generator (VSG) has gradually become prominent. In view of the situation that the grid impedance ratio (R/X) is high and affects the transient power angle stability of VSG, this paper proposes a VSG transient power angle stability control strategy based on the combination of frequency difference feedback and virtual impedance. To improve the transient power angle stability of the VSG, a virtual impedance is adopted in the voltage loop to adjust the impedance ratio R/X; and the… More >

Abstract Background: Although previous studies indicate that perceived social support might be associated with adolescent psychological problems, the specific mechanism has not been thoroughly discussed. Based on theoretical and empirical research on problematic Internet use (PIU) and sleep quality, this study explored whether they play a mediating role between perceived social support and symptoms of depression and anxiety among adolescents. Furthermore, we investigated whether these relationships varied by place of residence. Methods: A sample of 2115 Chinese adolescents was included, and analyzed data related to perceived social support, PIU, sleep quality, symptoms of depression and anxiety,… More >

Abstract Sweet potato leaves are consumed globally for their nutritional and functional properties, with their taste characteristics significantly influencing their market value and consumer acceptance. However, the metabolic factors determining the taste of sweet potato leaves remain unclear. This study evaluated the taste and metabolic profile of sweet potato leaves cultivated in soil and hydroponic systems, revealing that hydroponic culture improved the taste of the leafy sweet potatoes. Using gas chromatography system (GC)-ToF-MS, 200 metabolites were identified, encompassing most plant metabolic pathways. A comparison of good-tasting vs. poor-tasting sweet potato leaves identified 71 metabolites associated with taste More >

Abstract Existing glass segmentation networks have high computational complexity and large memory occupation, leading to high hardware requirements and time overheads for model inference, which is not conducive to efficiency-seeking real-time tasks such as autonomous driving. The inefficiency of the models is mainly due to employing homogeneous modules to process features of different layers. These modules require computationally intensive convolutions and weight calculation branches with numerous parameters to accommodate the differences in information across layers. We propose an efficient glass segmentation network (EGSNet) based on multi-level heterogeneous architecture and boundary awareness to balance the model performance… More >

Abstract The generalized finite difference method (GFDM), which cooperated with the fictitious-nodes technique, is proposed in this study to accurately analyze three-dimensional boundary value problems, governed by high-order partial differential equations. Some physical applications can be mathematically described by boundary value problems governed by high-order partial differential equations, but it is non-trivial to analyze the high-order partial differential equations by adopting conventional mesh-based numerical schemes, such as finite difference method, the finite element method, etc. In this study, the GFDM, a localized meshless method, is proposed to accurately and efficiently solve boundary value problems governed by… More >

Abstract Heat transport has been significantly enhanced by the widespread usage of extended surfaces in various engineering domains. Gas turbine blade cooling, refrigeration, and electronic equipment cooling are a few prevalent applications. Thus, the thermal analysis of extended surfaces has been the subject of a significant assessment by researchers. Motivated by this, the present study describes the unsteady thermal dispersal phenomena in a wavy fin with the presence of convection heat transmission. This analysis also emphasizes a novel mathematical model in accordance with transient thermal change in a wavy profiled fin resulting from convection using the… More >

Abstract Background: Youth emerge as an essential period in forming lifelong health and well-being. During adolescence, physical activity (PA) improves cardiovascular health, fitness levels, and the prevention of chronic illnesses, and the positive effect is also extended to the mental realm, as PA reduces symptoms of anxiety and depression. Therefore, the current study aims to enhance our understanding of the correlation between sports participation and depressive symptoms. Additionally, it seeks to explore how demographics such as gender, age, and race can shape these connections. Methods: The research sample was established by utilising the U.S. Youth Risk… More >

Abstract Background: With the decline of birth population and the development of medical technology in China, studies assessing how these changes have affected the adoption of congenital heart disease surgery at the national or regional scale are lacking. Methods: We investigated the status of congenital heart surgery in China in the period from 2017–2022, through investigation of the total rates of cardiac surgeries, cardiopulmonary bypass (CPB), adult congenital heart surgeries (CHS), and pediatric CHS (<18 years old), as recorded by the Extracorporeal Circulation Branch of the Chinese Society of Biomedical Engineering. Subsequently, we evaluated correlations between… More >

Abstract Spontaneous droplet transport has broad application prospects in fields such as water collection and microfluidic chips. Despite extensive research in this area, droplet self-transport is still limited by issues such as slow transport velocity, short distance, and poor integrity. Here, a novel cross-hatch textured cone (CHTC) with multistage microchannels and circular grooves is proposed to realize ultrafast directional long-distance self-transport of multi-scale droplets. The CHTC triggers two modes of fluid transport: Droplet transport by Laplace pressure difference and capillary suction pressure-induced fluid transfer in microchannels on cone surfaces. By leveraging the coupling effect of the… More >
