Electrical‐Programming‐Free Neural Crossbars Enabled by Photochemical Weight Patterning

ABSTRACT Hardware neural networks based on crossbar architectures require reliable implementation of multilevel synaptic weights, yet conventional electrical programming often suffers from programming interference, device variability, and write–verify overhead. Here, we present e...

Quantifying informational illiquidity in corporate bond markets

We develop a structural credit-risk model to quantify the impact of information asymmetry on corporate bond pricing. In the model, bondholders (i) sell their bonds either to meet liquidity needs or to exploit informational advantages and (ii) have the option to credibly reveal th...

Electrolyte Lubricants for Solid-State Batteries

Abstract Solid-state batteries (SSBs) promise higher energy density and improved safety, but interparticle voids and unstable solid–solid interfaces still limit their performance. Here, we translate the concept of lubrication into an electrolyte-lubrication strategy for SSBs. We...

Thermal management and cycle life enhancement of Lithium-ion Battery packs using low-fin tubes: Electrochemical-thermal-aging modelling and geometric optimization

Air cooling remains the most widely adopted thermal management strategy for lithium battery packs due to its simplicity and reliability. Thus, improving cooling efficiency and temperature homogeneity remains critical for such methods. Herein, this study proposes a low fin tube (L...

Expanding super‐resolution microscopy to semiconductor materials through fluorescence contrast engineering

Abstract Super‐resolution microscopy (SRM) has revolutionized biological imaging by overcoming the diffraction limit. However, its application to semiconductor materials has remained limited owing to the lack of effective strategies for generating material‐selective fluorescence...

Effects of transfer learning on seedling detection from drone imagery: a layer freezing study with faster R-CNN

Effective decision-making in forest management relies on accurate and timely data, yet conventional manpower-based methods often fail to provide sufficient coverage. This study develops a cost-effective, deep learning–based monitoring technique for assessing replanted areas follo...

Laboratory Stewardship: Improving Quality of Care by Linking Clinical Outcomes to Appropriate Test Utilization in Clinical Chemistry Laboratories

Stewardship of laboratory services aims to ensure appropriate test utilization and improve patient outcomes. However, clinical chemistry initiatives have largely focused on reducing test volumes and costs rather than linking interventions to clinical outcomes. This review examine...

Deployment-Oriented Evaluation of Lightweight IMU-Based Human Activity Recognition: On-Device Efficiency and Streaming Feasibility

On-device Human Activity Recognition (HAR) requires balancing accuracy and deployment efficiency on constrained hardware. We present Lightweight Human Activity Recognition (L-HAR), a controlled comparison of Baseline and Lightweight Temporal Convolutional Network (TCN), Transform...

Emerging Post‐CMOS Hardware Neurons for Brain‐Inspired Computing: Devices, Circuits, and System Integration

ABSTRACT The fundamental energy and latency limitations of the von Neumann architecture have necessitated a paradigm shift toward neuromorphic systems. This approach addresses the “memory wall” bottleneck by emulating the brain's event‐driven and massively parallel processing cap...

From Stigma to Spectacle: The Sociocultural Transformation of DanceSport in South Korea, 1900s–2020s

Social dance in Korea evolved from a stigmatized and heavily regulated activity into the institutionalized form of DanceSport. This transformation was not a straightforward process of diffusion or legal recognition but a contested historical trajectory through which cultural legi...

Nanocube-size-dependent Fermi level positioning in Cu2O/TiO2 S-scheme heterojunctions for optimized VOC photodegradation

Precise tuning of the Cu 2 O Fermi-level position is achieved by tailoring its crystal size (30, 55, and 315 nm). The Fermi-level position of Cu 2 O and the resulting interfacial electronic structure of Cu 2 O/TiO 2 S-scheme heterojunctions (CT-x: x= edge length in nm) have been...

Passivation-Dependent Device-Level Thermal Robustness of Indium Gallium Oxide Thin-Film Transistors under Dynamic Random-Access Memory Relevant 600 °C Nitrogen Annealing

As conventional silicon-based dynamic random-access memory (DRAM) approaches its physical and electrical scaling limits, oxide semiconductors have emerged as promising channel materials for next-generation memory devices because of their low off-state current and process compatib...

Structural hybridization of polydiacetylene-based composites: From molecular Signaling to multifunctional sensing architectures

Abstract Polydiacetylenes (PDAs) are widely studied stimuli-responsive materials owing to their characteristic chromatic transition originating from conformational changes in the conjugated backbone. However, practical applications are limited by structural instability, weak sign...

Integrating Environmental Value Into Mobility‐as‐a‐Service: Behavioral Insights for Sustainable Mobility Strategy

ABSTRACT Mobility‐as‐a‐Service (MaaS) offers an integrated solution for sustainable urban transport. However, user adoption remains limited, and individuals' valuation of environmental performance is poorly understood. This study empirically examined sustainability‐oriented prefe...

Clinical Setting-Based Medical Care of Transgender and Gender-Diverse Individuals in East Asia: A Scoping Review

Purpose:Transgender and gender-diverse (TGD) individuals in East Asia face significant structural barriers in health care utilization, yet systematic evidence focusing on clinical delivery remains scarce. This scoping review mapped available evidence on clinical setting-based med...

Understanding the determinants influencing middle-aged and elderly users’ continuous use intention of mobile news apps

Optimized Cas9‐Enriched Nanopore Sequencing and Analysis Workflow for Clinical Diagnosis of Repeat Expansion Disorders

Short tandem repeat (STR) expansion is a major genetic mechanism underlying numerous neurogenetic disorders. However, traditional PCR amplification and short-read next-generation sequencing-based methods often fail to detect large-scale, complex expansions and to capture methylat...

Weak Cross-Assemblage Concordance of Survey-Round Community Dissimilarity in Korean Lotic Waters: A Matched National Biomonitoring Analysis

National biomonitoring programs increasingly survey multiple biological assemblages, but whether one biological element can serve as a surrogate for the magnitude or ranking of repeated-survey compositional displacement remains unresolved under strict site-year-round matching. We...

Geographic and perceptual bias in multimodal LLMs: evidence from a global dataset spanning more than 200 cities

Multimodal large language models (MLLMs) are increasingly deployed for urban informatics applications, from objective built environment attribute extraction to subjective assessments. However, do MLLMs apply the same standards across regions while executing these urban-related ta...
