Multiphysics-Based Numerical Prediction of the Electromagnetic and Thermal Performance of a 160 kW SSDR Axial-Flux Motor

Axial-flux motor (AFM) can achieve high torque and power density; however, integrated electromagnetic and thermal design is required to manage losses and heat generation during high-power operation. In this study, an AFM with a target output power of 160 kW for electric vehicles...

Nondestructive prediction of textural properties of model plant-based meat analogs prepared with sesame seed meal protein isolate using hyperspectral imaging

Abstract Texture, a key quality attribute in plant-based meat analogs (PMAs), is conventionally evaluated using destructive methods. This study evaluated the use of hyperspectral imaging (HSI) coupled with partial least squares regression (PLSR) for the nondestructive prediction...

The relationship between political YouTube news use and affective polarization in election vs. non-election contexts: mediation by hostile expression and moderation by political rumor acceptance

User-generated political YouTube channels often disseminate conspiracy narratives and partisan information, potentially reinforcing echo-chambers and intensifying hostility toward political outgroups. Against this backdrop, this study examines the interplay among political YouTub...

Robust link prediction in heterogeneous graphs via diffusion-based generative fusion and relation-aware guidance

Link prediction in heterogeneous graphs, which captures both topological and semantic information in graph structures helps the discovery of meaningful relationships. However, several fundamental challenges of link prediction remain insufficiently addressed. First, real-world dat...

Factors Associated with Health-Promoting Behaviors among Late Middle-Aged Women: Focusing on Aging Anxiety, Social Support, Self-Efficacy, and Physiological Indicators

Purpose: The purpose of this study was to identify the relationships between aging anxiety, social support, and self-efficacy, and to determine the factors influencing health-promoting behaviors among late middle-aged women. Methods: This study utilized a descriptive research des...

Effects of autoclave holding duration and nano-SiO2/TiO2 replacement on hydration products and pore structure of pressed reactive powder concrete

This study investigated the effects of autoclave holding duration and nano-inorganic powder modification on the mechanical and microstructural development of pressure-formed reactive powder concrete (RPC). Nano-silica (NS) and nano-TiO 2 (NT) were incorporated at replacement leve...

Integrated physical property measurements of titanium-bearing and host rocks for mineral exploration

Titanium is a critical mineral whose growing demand requires efficient methods for resource characterization and exploration. This study presents integrated physical property measurements of titanium-bearing ores and associated host rocks from the Myeonsan titanium ore deposit, S...

Automatic and User-Centered Evaluation of an AI-Driven Korean Recipe RAG Chatbot: Alignment, Mismatch, and Actionability

Users with limited cooking experience must simultaneously consider multiple factors, including available ingredients, cooking time, cooking equipment, health conditions, personal preferences, and practical feasibility. Therefore, simple keyword-based recipe searches make it diffi...

Qualitative analysis of improved order Hilfer fractional feedback control differential inclusions with Volterra-integral

This work primarily aims to investigate the existence of feedback control for a class of Hilfer fractional integro-differential inclusions of order 1<η<2. Initially, we establish sufficient conditions using fractional calculus, cosine families, multivalued mappings, Volterra inte...

Bifurcation analysis of continuous and discrete time predator-prey models with habitat complexity

This paper investigates a predator-prey model with a Holling Type II functional response in the presence of habitat complexity. The model is formulated in continuous time and discretized using the forward Euler scheme to obtain its discrete counterpart. Fundamental dynamical prop...

Mechanical performance of polyvinyl alcohol macrofiber‐reinforced very‐early‐strength latex‐modified concrete for early‐opening pavement repair

Abstract Very‐early‐strength latex‐modified concrete (VES‐LMC) is widely used for emergency pavement repairs requiring rapid opening to traffic; however, improving mechanical performance while maintaining early‐age strength remains a challenge. This study evaluates the effectiven...

Cudrania tricuspidata Leaf-Derived Polysaccharides Attenuate Cisplatin-Induced Cytotoxicity in HEK 293T Cells via the Nrf2/HO-1 Pathway

Prolonged administration of cisplatin, a widely used chemotherapeutic agent, induces nephrotoxicity. Identifying natural compounds that attenuate cisplatin’s adverse effects on renal tissues would be of clinical value. Thus, the present study aimed to evaluate the cytoprotective...

LLM-Assisted Initial Population Generation for Multi-Objective Joint Service Placement and Traffic Routing in 6G Networks

In forthcoming 6G networks beyond 5G, services with increasingly stringent performance requirements are expected to emerge, requiring dynamic and flexible service placement and traffic routing. Furthermore, the integration of non-terrestrial networks for global coverage introduce...

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

ABSTRACT We investigate the physical origins of resonance effects in one‐dimensional periodic photonic lattices (PhL), focusing on the relative roles of Fabry–Perot (FP), Mie, and guided‐mode resonance (GMR) mechanisms. Using rigorous numerical simulations and modal analysis, we...
