Discovery of Energy‐Localized Trap States via Opto‐Electrical Spectroscopy in UWBG Perovskite La:SrSnO 3 FETs

ABSTRACT Strontium stannate perovskite (SrSnO 3 ) is emerging as a promising material for next‐generation ultra‐wide bandgap (UWBG) semiconductors due to its high electron mobility and optical transparency. However, despite the critical importance of defect analysis to utilize La...

Adaptive Temporal Reallocation and Trajectory-Aware Modulation for Event-Level Segmentation of Small-Scale UAVs

Event-level segmentation of small-scale unmanned aerial vehicles (UAVs) is challenging because target-generated events are sparse and are easily mixed with background motion and sensor noise. This study extends EV-SpSegNet with Adaptive Temporal Reallocation (ATR), Trajectory-Awa...

An Action-Centric Zero Trust Maturity Model for Agentic AI Environments

Large language model–based agentic AI systems can independently interpret user goals, develop plans, and interact with external tools. These capabilities introduce security concerns that extend beyond traditional access control. However, existing Zero Trust Maturity Models, such...

Structural and electrochemical investigation of Fe-doped sheet-like ZnCo₂O₄ as battery-type electrode for high-performance hybrid supercapacitors

Multi-transition metal spinel oxides with nanostructures have become interesting options for improving the electrochemical performance of next-generation supercapacitors. By synthesizing pure ZCO, 5% Fe-doped ZCO, and 10% Fe-doped ZCO, the structural and electrochemical effects o...

Assessing diabetes risk factors using explainable AI and SMOTEENN: a nutrition-based analysis in South Korea

The coronavirus disease (COVID-19) pandemic has influenced diabetes risk and management at the population level, underscoring the need for interpretable and data-driven risk assessment approaches. We developed an explainable machine learning framework integrating the KNHANES and...

Culturally adapted wearable mobile health intervention for physical activity and cognitive function in middle-aged Koreans: a pilot feasibility study

BACKGROUND: Middle adulthood (45-64 years) represents a critical window for the primary prevention of cognitive decline and chronic diseases, with physical activity capable of reducing later cognitive decline by 20% to 35%. However, most evidence on mobile health (mHealth) interv...

Explainable Multi-Objective Quantum-Inspired Fuzzy Optimization of Rule Bases for Scalable Load Balancing in Multi-Factor Computing Environments

The rapid growth of cloud and distributed computing systems has increased the complexity of real-time request distribution under dynamic and multi-factor conditions. In such environments, load-balancing decisions must simultaneously consider uncertain and interdependent parameter...

Identification active compounds from Dregea volubilis that improve insulin secretion by regulating pancreatic β ‐cell metabolism

Abstract Type 2 diabetes (T2D) occurs due to a lack of insulin secretion by glucose stimulation, so high blood glucose levels predominate that associated with metabolic dysregulation. The exploration of bioactive compounds from natural sources has attracted considerable attention...

Rational Designof Pyrrole-Based Ionizable Lipidsfor mRNA Delivery

Abstract Ionizable lipids are key components of lipid nanoparticles for mRNA delivery. Inspired by the DLin-KC2-DMA ionizable lipid, we developed a series of pyrrole-based ionizable lipids to evaluate the feasibility of incorporating a rigid heterocyclic scaffold into ionizable l...

Synthesis and Comparative Electrochemical Evaluation of Polymer Cobalt Phthalocyanine and SWCNT-Modified Composite as High-Performance Anode Materials for Lithium-Ion Batteries

The development of high-performance anode materials remains a key challenge for advancing lithium-ion battery (LIB) technology. In this work, an oxy-bridged polymer cobalt phthalocyanine (Poly-CoPc) and its single-walled carbon nanotube-modified composite (Poly-CoPc/SWCNT) were s...

Integrative Genomic Analysis Reveals Molecular and Clinical Disparities between Bladder and Upper Tract Urothelial Carcinoma in K-MASTER Program

Purpose: The clinical outcome of urothelial carcinoma presents significant variability, reflecting its molecular composition, epidemiologic attributes, and primary site of origin. Despite histological similarities, upper tract urothelial carcinoma (UTUC) and bladder urothelial ca...

A Closed-Loop Measurement Study of Runtime Governance in AI-Driven Smart Building Climate Control

Which runtime governance mechanisms reduce physical risk when a learned controller drives a building’s climate, and under what conditions? We develop a closed-loop software-in-the-loop testbed in which a setpoint model trained on real occupancy data drives a physics-based thermal...
