Dynamics-aware hierarchical decision–control with egocentric perception for robust navigation of underactuated uncrewed surface vehicles

Reliable navigation of underactuated uncrewed surface vehicles (USVs) in complex waters depends on the consistency between adaptive decision-making and physically executable motion under nonlinear dynamics and environmental disturbances. Existing deep reinforcement learning metho...

Ultra-sensitive 2D Dion−Jacobson perovskite phototransistors for optoelectronic neuromorphic computing

Metal halide perovskite semiconductors demonstrate significant advantages over traditional semiconductor materials in next-generation weak-light-responsive devices, owing to their exceptional photoelectric conversion capabilities and outstanding charge transport properties. Under...

We need support! Examining hospitality employees’ AI anxiety and job insecurity: the moderating role of organizational support

Purpose The purpose of this study is to investigate the level of hospitality employees’ anxiety about AI technology and its impact on their job insecurity and turnover intention. Additionally, this study examines the direct impact of organizational support on job insecurity, affe...

Dynamic Hydrophobic Liquid Interphase Engineering: A New Paradigm for Advanced Aqueous Zinc Batteries

ABSTRACT The narrow electrochemical stability window of water, together with the interfacial instability at the Zn and electrolyte interface, continues to pose key barriers to the practical development of high‐energy aqueous zinc batteries. In a recent advance, Li et al. reported...

Beyond 2D land consumption: A scaling-law framework for evaluating 3D urban space consumption and population dynamics in fifteen East Asian megacities

As cities expand both outward and upward, assessing global urbanization requires a three-dimensional perspective that captures the complete picture of urban growth. However, conventional land-consumption metrics fail to capture vertical intensification, while large-scale building...

CCS deployment policy choices under regional heterogeneity: Economy-wide impacts and spillovers in China

Carbon capture and storage (CCS) is critical for decarbonizing the fossil-energy power sector, the world's largest source of greenhouse gas emissions. However, how deployment responsibilities should be allocated across heterogeneous regions to deliver economy-wide economic and en...

Kinetic-Controlled Ultrafast Synthesis of Ordered Intermetallic Nanoparticles

Abstract The disorder–order transition of metal alloys delivers ordered intermetallic nanoparticles (NPs) as efficient and stable catalysts. However, this transition is practically challenging due to the thermodynamically low driving force and the complex kinetic competition with...

Systematic Parameter‐Space Mapping Strategy for a Deep‐Subwavelength‐Thick Low‐Frequency Electromagnetic Metasurface Absorber

ABSTRACT Overcoming the intrinsic thickness–frequency trade‐off while simultaneously ensuring ultra‐thinness, wide‐angle absorption, and mechanical conformability remains a fundamental challenge in designing electromagnetic (EM) absorbers for next‐generation integrated systems. H...

The effects of repetitive transcranial magnetic stimulation on executive functions in healthy and at-risk older adults: a systematic review and meta-analysis

Cognitive flexibility, inhibitory control, and working memory are core executive functions and early vulnerable cognitive domains across the continuum from healthy aging to mild cognitive impairment, highlighting the need for preventive interventions before substantial neurodegen...

Within-person associations between fear of missing out and cyberbullying victimization: An ecological momentary assessment study

Several psychological factors (e.g., personality, mental health, and behavioral problems) have been linked to cyberbullying victimization. However, relatively little research has examined fear of missing out (FoMO) in relation to cyberbullying victimization. Existing studies have...

Flexural behavior and debonding mechanism of RC beams strengthened with FRP mini-bars embedded in geopolymer matrix

Carbon fiber-reinforced polymer (CFRP) offers an efficient strengthening solution, however, pursuing higher load capacities via high reinforcement ratios triggers premature interfacial debonding. Basalt FRP (BFRP) serves as a cost-effective alternative, inherently alleviating int...

Intranasal delivery of BDNF-enriched small extracellular vesicles ameliorates cognitive impairment and Alzheimer’s disease-like pathology in APP/PS1 mice

Alzheimer’s disease (AD), the leading cause of dementia, still lacks broadly effective disease-modifying therapies. Here, we engineered brain-derived neurotrophic factor (BDNF)-enriched small extracellular vesicles (BDNF-sEVs) from human induced pluripotent stem cell-derived mese...

Three-year Comparative Efficacy and Safety of Repeated Low-level Red-light Therapy and Orthokeratology for Myopia Control in Children

Repeated low-level red-light therapy (RLRL) has emerged as a noninvasive intervention for myopia control in children. This study compared the 3-year efficacy and safety of RLRL and orthokeratology (OK). This retrospective study included 86 children treated with RLRL ( n = 40) or...

On Realization of Back‐Action‐Evading Measurements and Quantum Non‐Demolition Variables via Linear Systems Engineering

ABSTRACT We establish a framework for realizing back‐action‐evading (BAE) measurements and quantum non‐demolition (QND) variables in linear quantum systems. The key condition, a purely imaginary Hamiltonian matrix with a real or imaginary coupling operator matrix, enables BAE mea...

Prediction of Joint Roughness Coefficient Using Metaheuristic-Optimized Random Forest Model

Reliable estimation of the joint roughness coefficient (JRC) is important for quantitative characterization of joint roughness and provides an important geometric parameter for subsequent joint shear strength assessment. However, single-parameter empirical models cannot fully cap...

Executive functions in Cantonese-English bilingual autistic and neurotypical children: The role of first and second language exposure across different communicative contexts

This study investigated the impact of first language (L1) and second language (L2) exposure on working memory and inhibitory control in 6- to 10-year-old Cantonese-English bilingual autistic children (N = 36, mean age = 8;05, SD = 1.02) and bilingual neurotypical children (N = 40...

Integrative plasma proteomic network analysis identifies physical activity-associated protein modules potentially mediating type 2 diabetes risk

Moderate-to-vigorous physical activity (MVPA) lowers the risk of type 2 diabetes (T2D). Identifying protein modules that mediate this association may help dissect these biological underpinnings, but they remain incompletely characterized. We studied 28,842 diabetes-free UK Bioban...

Chamber-to-Field Development and Validation of Integrated Filtration–Adsorption Air Cleaners for Particle and VOC Control in Shipboard Cabins

Shipboard cabins can contain both oil mist-dominated particulate matter and volatile organic compounds (VOCs), creating a need for compact air-cleaning systems capable of simultaneous particle and gas-phase removal. This study developed an integrated filtration–adsorption air cle...

Enhancing Healthy Longevity: Scoping Review of Practices and Interventions

BACKGROUND: Over the past two decades, concerns have arisen about the distinction between health span and lifespan, highlighting that longevity does not necessarily equate to good health, a concept often referred to as "healthy longevity." While various strategies have been explo...
