Fe 3 d Electron Delocalization in Asymmetric Fe Single Atoms Enables Nonradical Peroxymonosulfate Activation for Micropollutant Degradation

Abstract Nonradical peroxymonosulfate (PMS) activation provides a selective route for micropollutant degradation, yet the orbital-level origin of oxidant speciation at single-atom sites remains unclear. Herein, an asymmetric Fe single-atom catalyst (Fe–N3–VN–C) is synthesized via...

From graph Laplacian to ring polymer dynamics: part I

Abstract A graph-theoretic formulation of overdamped Langevin dynamics and constitutive equations for ring polymers is developed. The polymer molecule is represented as a bead–spring network whose connectivity is described by a graph Laplacian. Starting from overdamped stochastic...

A Cache Modeling Framework for Accelerator Systems

Modern hardware accelerators increasingly rely on cache-based memory systems to improve modularity and tolerate irregular memory behavior in sparse and data-dependent workloads. However, configuring accelerator caches remains challenging: designers must choose cache capacity, Mis...

The global cardiovascular-kidney-liver-metabolic burden from 1990 to 2023

Background The cardiovascular-kidney-liver-metabolic (CKLM) framework represents the multi-organ interplay of systemic metabolic disorders that drive the global burden of cardiovascular diseases (CVD). Methods This study is a descriptive epidemiological analysis of the Global Bur...

Implementing telemedicine under polycrisis: a mixed-methods case study from Myanmar using the RE-AIM framework

Myanmar’s March 2025 7.7-magnitude earthquake intersected with conflict, governance breakdown, and economic collapse, leaving 12.9 million people needing health assistance, yet evidence on how telemedicine functions under such polycrisis conditions remains limited. We conducted a...

Highly Tunable Schottky Barrier to 2D Semiconductors Enabled by an Inorganic‐Molecular‐Crystal Tunneling Layer

ABSTRACT Effective tuning of the Schottky barrier, which determines charge transport across the metal‐semiconductor interface, is essential for optimizing the performance of electronics and optoelectronic devices. However, interfacial disorders and orbital overlap between metals...

Engineering Biomimetic Tumor Organoids Inspired by Janus Stiffness–Driven Cell Stemness

ABSTRACT Organoids become powerful platforms for modeling cancer biology but poorly preserve stemness due to inadequate biophysical cues. Cancer stem cells (CSCs), crucial for tumor growth, are rare and lose stemness under conventional in vitro conditions, limiting drug screening...

A Simple and Adaptive Confidence Interval when Nuisance Parameters Satisfy an Inequality

Inequalities may appear in many models. They can be as simple as assuming a parameter is nonnegative, possibly a regression coefficient or a treatment effect. This paper focuses on models with one inequality and proposes an inequality-imposed confidence interval (IICI) that has p...

On additive averaging kernels for finite Markov chains

Abstract We study additive mixtures of Markov kernels of the form $$A_\alpha = \alpha P + (1-\alpha )G$$ A α = α P + ( 1 - α ) G , where $$\alpha \in [0,1]$$ α ∈ [ 0 , 1 ] , P is a baseline sampler and G is a Gibbs kernel induced by a partition of the state space. We first motiva...

Uncovering the Associations between Human Big Five Personality Traits and Built Environment Characteristics from Street View Imagery

Human–environment interactions, a classic topic in geography, suggest that individuals and their environments might shape each other. Yet the specific mechanisms underlying these interactions regarding human personality traits have not been explored. This study examines the assoc...

Surface-Charge-Regulated MoS2 Membrane for Induced Agglomeration and Efficient Removal of Nanopollutants

Abstract Conventional membranes for nanopollutant removal are constrained by the permeability–selectivity trade-off inherent in size-exclusion mechanisms. Here, we report a surface-charge-regulated MoS2 membrane engineered by anchoring copper nanoparticles and quaternary ammonium...

Motion enhances camouflage: Retinal evidence for flicker fusion camouflage in jumping spiders

Camouflage is often assumed to fail once prey move, yet theory predicts that rapid motion can reduce detectability through flicker fusion camouflage (FFC), where high-contrast patterns blur into perceptual uniformity. We tested this prediction using retinal tracking in the jumpin...

Small-Molecule-Directed RNA Modification via Proximity-Driven Catalysis

Abstract Selective chemical modification of RNA is essential for RNA functionalization, probing RNA structure–function relationships and developing RNA-targeted therapeutics. Existing chemical strategies often rely on guanine accessibility or multiple helper DNA strands, restrict...

Atomically thin amorphous carbon with an ultralow dielectric constant

Two-dimensional (2D) materials could replace conventional electronic components. Key advances have already been made in applying 2D materials to integrated circuits, but a robust, atomically thin ultralow-k dielectric remains crucial for further circuit scaling. Minimizing parasi...

Proteomic Profiling of Human Sweat Reveals Molecular Adaptations to Heat Acclimatization Induced by Isothermic Conditioning

Introduction: Prolonged physical exertion in hot and/or humid environments can induce physiological strain and increase the risk of heat exhaustion or exertional heat stroke (EHS). Heat acclimatization (HA) optimizes an individual’s ability to tolerate heat and is therefore widel...

Engineering Hidden Ferroelectric‐Like Distortion for Ultralow Thermal Conductivity in Polar van der Waals Tetradymite

ABSTRACT Ferroelectric‐like polar structures enable diverse functionalities through coupling with charge and phonon transport. Although effective in modulating thermal conductivity, the rational design of novel polar materials with intrinsically low thermal conductivity via ferro...

From “Caring for the home” to “Caring for the environment”: Migrant Domestic Workers and Circular Household Waste Management in Singapore

This article advances a relational feminist approach to better understand the roles that migrant domestic workers play in their everyday handling of household waste in Singapore. Despite emerging scholarly emphasis on the feminization of waste work in circular transitions, the ou...
