Racial gap in attitudes on support for military actions

Research on public support for military force has documented recurring Black–White differences, but less is known about Hispanic and Asian respondents or how racial gaps vary across military missions. Using Cooperative Election Study (CES) data from 2008 through 2024, the analysi...

Dual‐Timescale–Based Cache and Bandwidth Control Scheme in Integrated Satellite‐Terrestrial Networks

ABSTRACT Recently, the integrated satellite‐terrestrial network (ISTN) system offers a promising solution for extending wireless communication services to remote and underserved areas. To effectively provide a variety of services, it is essential to cache the corresponding servic...

Exact four-parameter rotating NS-NS vacuum in double field theory

A bstract We construct an exact rotating vacuum of the NS-NS sector, equivalently a Double Field Theory vacuum. The construction applies compact SO (2) S-duality to a rotating Einstein-scalar seed. The solution has four independent parameters $$ \left\{\mathfrak{m},j,\mathfrak{q}...

Nanolayer-Confined Strain Waves in Femtosecond-Optical-Vortex-Excited Multiferroic BiFeO3

Abstract Strain waves provide a route to reshape nanoscale order in functional materials, where lattice deformation couples to charge and spin degrees of freedom. Real-space tracking of these transient strain fields is critical for connecting acoustic excitation to functionality,...

Review and optimization of image classification models for edge AI applications

Image classification on edge devices requires models that maintain accuracy while reducing inference cost. This paper reviews the development of image classification models from convolutional neural networks to Vision Transformer models and examines their relevance to edge artifi...

Antimony-contact MoS2 FET gas sensors for reinforcement-learning–driven hazard perception at room temperature

Two-dimensional van der Waals semiconductors promise low-power chemical perception at room temperature, yet contact-limited on-currents and slow recovery impede closed-loop decision making in hazardous environments. Here we propose antimony (Sb)-contact two-dimensional (2D) monol...

Improving OER performance in alkaline water electrolysis with a Zn-doped NiFe LDH electrode developed via self-growth precipitation

Developing cost-effective, scalable non-noble-metal electrocatalysts for the oxygen evolution reaction (OER) is essential for alkaline water electrolysis (AWE). Zn-doped NiFe layered double hydroxide (LDH) was synthesized via self-growth precipitation. Zn-incorporated NiFe LDH ex...

Quantum Dot-Induced Kinetic Bottleneck in Singlet Exciton Relaxation of Conjugated Polymer Aggregates

Abstract We designed hybrid aggregate model systems with cascade energy alignment from conjugated polymers (CPs) to quantum dots (QDs) to investigate the effects of QDs on CP singlet (S1) excitons. Radiative recombination of S1 excitons occurs within 1 ps in the chlorinated CP/QD...

When market orientation backfires: the asymmetric effects of proactive and responsive orientation on marketing capabilities and performance

Purpose This study aims to examine how proactive and responsive market orientations (RMOs) are associated with the development of digital and traditional marketing capabilities (TMCs) in business-to-business (B2B) small and medium-sized enterprises (SMEs), and how those capabilit...

WACA-UNet: Weakness-Aware Channel Attention for Static IR-drop Prediction

Accurate spatial prediction of power-integrity issues such as IR drop is critical for reliable VLSI design, yet traditional simulation-based solvers do not scale efficiently to modern designs. We formulate static IR drop estimation as a pixel-wise regression problem over heteroge...

Reversing the Readability Paradigm: A Systematic Literature Review and Visual Comprehension Framework for AI-Generated Cloud Backend Code

The history of software engineering tools has been oriented toward a singular direction: translating human intent into machine-executable form. The emergence of AI-powered coding agents capable of autonomously generating production-grade backend infrastructure code has inverted t...

Administrative district reforms, Land Transaction Permission System, and land market dynamics: Evidence from South Korea

Abstract This study examines how administrative jurisdictional reform affects land market dynamics by analyzing the 2023 incorporation of Gunwi County into Daegu Metropolitan City, South Korea. We develop a supply‐and‐demand framework in which administrative reclassification rais...

Deterministic Switching‐Path Engineering of CMOS‐Integrated 2D Memristors for Neuromorphic Computing

ABSTRACT Two‐dimensional (2D) memristors are promising for low‐power and high‐speed neuromorphic hardware. However, their performance under circuit‐level constraints remains limited because resistive switching relies on native defects, hindering precise control of filament format...

Designing an MR-Based Educational System for Open-Storage Art Museums: A Case Study of MMCA Cheongju

Open storage museums offer a distinctive mode of exhibition by publicly displaying collections within storage environments. However, high-density displays without sufficient interpretive support often confine visitors to passive observation, giving rise to what has been described...

Scalarized Extremal Black Holes in the Einstein–Maxwell-Scalar Theory with Two U(1) Fields

We study scalarized extremal black holes in the Einstein–Maxwell-scalar (EMS) theory with two different scalar couplings to two U(1) fields. This theory is inspired by the dyonic EMS theory. Two scalarized extremal black holes are found with constant scalar hair. We confirm that...

Metal- and polymer-assisted SEM imaging of protein-bound DNA molecules: a protocol

Abstract Direct mapping of protein positions along long, stretched DNA molecules requires simultaneous visualization of the DNA backbone and associated protein signals. We recently established a heavy-metal- and polymer-assisted scanning electron microscopy (SEM) approach for ima...

Reasoning-Driven Design of Single-Atom Catalysts via a Multiagent Large Language Model Framework

Abstract Large language models (LLMs) are becoming increasingly applied beyond natural language processing, demonstrating strong capabilities in complex scientific tasks that traditionally require human expertise. This progress has extended into materials discovery, where LLMs in...
