Abstract Modifications in fuel spray characteristics fundamentally influence fuel–air mixing dynamics in diesel engines, thereby significantly affecting combustion performance and emission profiles. This study explores the operational behavior of RP-5 aviation kerosene/diesel blended fuels in marine diesel engines. A spray visualization platform based on Mie scattering technology was developed to comparatively analyze the spray characteristics, ignition behavior, and soot emissions of RP-5 aviation kerosene, conventional-35# diesel, and their blends at varying mixing ratios (D100H0, D90H10, D70H30, D50H50, D30H70, D0H100). The findings demonstrate that, under constant injection pressure, aviation kerosene combustion results in a more uniform temperature More >

Abstract The present study investigates the dynamic behavior of a ternary-hybrid nanofluid within a tapered asymmetric channel, focusing on the impact of unsteady oscillatory flow under the influence of a magnetic field. This study addresses temperature-sensitive water transport mechanisms relevant to industrial applications such as thermal management and energy-efficient fluid transport. By suspending nanoparticles of diverse shapes-platelets, blades, and spheres in a hybrid base fluid comprising cobalt ferrite, magnesium oxide, and graphene oxide, the study examines the influence of both small and large volume fraction values. The governing equations are converted into a dimensionless form. With More >

Abstract The local overheating issue is a serious threat to the safe operation of data centers (DCs). The chip-level liquid cooling with pool boiling is expected to solve this problem. The effect of nano configuration and surface wettability on the boiling characteristics of copper surfaces is studied using molecular dynamics (MD) simulation. The argon is chosen as the coolant, and the wall temperature is 300 K. The main findings and innovations are as follows. (1) Compared to the smooth surface and fin surface, the cylindrical nano cavity obtains the superior boiling performance with earlier onset of… More > Graphic Abstract

Abstract The rigidity of the resin matrix is a critical factor affecting the impact resistance of composites [1]. However, the intrinsic relationship between resin matrix rigidity and ballistic performance remains insufficiently understood. To reveal the influence mechanisms of resin matrix rigidity on ballistic performance, this study compares the ballistic limits of PBO-140, PBO-200, Aramid III, and Aramid II fiber reinforced composites with resin matrices of different rigidities (epoxy resin, PX90, and PX30) through ballistic impact tests. The experimental results show that, the ballistic limit of composites with PX90 resin is higher than that of composites with… More >

Abstract Background: It has been broadly witnessed that a large number of adolescents are suffering emotional and mental health problems after COVID-19, and such adverse experiences in early life often extend into adulthood, resulting in serious long-term implications. However, it is accepted that the literature examining the relationship between mental health problems in adolescents and their underlying psychological factors is limited. The purposes of the current study were to identify mental health problems of Korean adolescents and to investigate the possible influence of self-esteem, self-efficacy, and health locus of control on mental health problems. Methods: A… More >

Abstract Background: Fundamental internal factors like self-construal and its influence on problematic online game use (POGU) remain underexplored. Hence, this study aims to investigate the effects of independent and interdependent self-construal on POGU, with the mediation of basic psychological needs satisfaction. Methods: The study surveyed 418 Chinese junior high school students (50.24% male; Mean_age = 12.68, SD = 0.65), assessing their levels of self-construal, basic psychological needs satisfaction, and POGU. A parallel mediation model was tested. Results: The findings showed that autonomy and competence needs satisfaction fully mediated the negative impact of independent self-construal on POGU (B… More >

Abstract Polymeric materials have emerged as a promising alternative to electrolytic solutions in energy storage applications. However, high crystallinity and poor ionic conductivity are the main barriers restricting their daily application. In this study, we propose a polymer electrolyte system consisting of methylcellulose-polyvinyl alcohol (MC-PVA) blend as host material and lithium trifluoromethanesulfonate (LiCF₃SO₃) as dopant, which was prepared using the solution-casting method. The electrochemical impedance spectroscopy (EIS) analysis revealed a maximum conductivity of 5.42 × 10⁻⁶ S cm⁻¹ with 40 wt.% LiCF₃SO₃. The key findings demonstrated that the variation in the dielectric loss (ε_i) and dielectric constant (ε_r) was… More >

Abstract Ice accretion on structures such as aircraft wings and wind turbine blades poses serious risks to aerodynamic performance and operational safety, particularly in cold and humid environments. This study conducts numerical simulations of ice formation on thin flat plates using CFD and FENSAP-ICE, exploring how air temperature, wind velocity, and angle of attack (AOA) affect icing behavior and aerodynamic characteristics. Results indicate that ice thickness increases linearly over time. Rime ice forms at low temperatures due to immediate droplet freezing, whereas glaze ice develops at higher temperatures when a water film forms and subsequently refreezes… More >

Abstract License plate recognition in haze-affected images is challenging due to feature distortions such as blurring and elongation, which lead to pixel displacements. This article introduces a Displacement Region Recognition Method (DR2M) to address such a problem. This method operates on displaced features compared to the training input observed throughout definite time frames. The technique focuses on detecting features that remain relatively stable under haze, using a frame-based analysis to isolate edges minimally affected by visual noise. The edge detection failures are identified using a bilateral neural network through displaced feature training. The training converges bilaterally… More >

Abstract In the production process of silicone sealant, mineral oil is used to replace methyl silicone oil plasticizer in silicone sealant to reduce costs and increase efficiency. However, the silicone sealant content in mineral oil is prone to premature aging, which significantly reduces the mechanical properties of the silicone sealant and severely affects its service life. At the same time, there are few reports on the simulation research of the performance of silicone sealant. In this study, three mixed system models of crosslinking silicone sealant/plasticizer are constructed by the molecular dynamics simulation method, and the effect… More >
