Adapting Zero Trust to University Laboratory Safety Governance in the Artificial Intelligence Era

In the artificial intelligence (AI) era, the structure of safety hazards in university laboratories is changing, with unconventional hazards making up a growing share. As AI evolves from an auxiliary tool into an autonomous research collaborator, interdisciplinary experiments are...

Wafer-scale low-symmetry graphene moiré superlattice for integrated quantum rectifiers

Low-symmetry materials unlock rich Berry curvature physics and anomalous transport phenomena that are forbidden in high-symmetry quantum systems through rigorous crystalline symmetry constraints. Current approaches rely on external fields or complex heterogeneous stacking to brea...

The effects of China's Major Function-Oriented Zoning on construction land expansion: The role of resource factors

Although strategic spatial planning is widely used to shape territorial development and protection, its effects on construction land expansion and the underlying mechanisms remain insufficiently examined. Using China's Major Function-Oriented Zoning (MFOZ) as a case, this study e...

Improved estimation of net ecosystem CO 2 exchange over North America using LSTM-based flux upscaling (2001–2021)

Accurate estimation of regional-scale terrestrial carbon budgets is of great importance but remains challenging. With particular advantages, the Long Short-Term Memory (LSTM) network method shows potential for improving regional carbon budget upscaling estimations. Here, using LS...

Strength in families: Parental resilience, marital dynamics, and adolescent anxiety and substance use

Abstract Drawing on Luthar’s relational framework of resilience, this study examines how parental resilience operates within marital dynamics to shape adolescent adjustment in Mexican-origin families. Using four waves of data from 604 families (M adolage = 12.41, SD = 0.97; 54.3%...

Fear of humans mediates spatiotemporal interactions between endangered large Asian felids

Abstract Species competitive interactions influence carnivore demography. Humans, as global ‘super predators,’ may mediate interactions among sympatric carnivores, although the effects of ecological fear on these interactions remain less understood. We used two years of camera tr...

A generalizable biopsychosocial risk score for stratifying disease vulnerability in healthy populations

Prospective risk stratification of future adverse health outcomes before clinical onset among ostensibly healthy individuals is an important goal of preventive and precision medicine, yet current tools remain largely disease-specific and do not provide an integrated measure of he...

Fenton-Mediated Surface Modulation of Microplastics: Effects and Mechanisms on the Fluorescence Response of Nile Red Staining

Abstract Nile Red (NR) fluorescence staining enables rapid microplastic (MP) screening, but weak dye affinity and matrix-derived false positives limit quantitative reliability. This study investigated whether controlled Fenton digestion can modulate microplastic surfaces to enhan...

Rethinking urban ecosystem service flow through human mobility: The neighborhood effect averaging problem

Daily exposure to ecosystem services (ES) plays an important role in improving urban residents' health; however, residents' actual contact with ES, referred to as ecosystem service flows, depends not only on local biophysical conditions of urban nature but also on human daily mob...

Extrapolating Molecular Correlation Energies to the Complete Basis Set Limit with Symbolic Regression

Abstract Basis set extrapolation is an important strategy for reducing basis set incompleteness error (BSIE) in correlation energy calculations. However, extrapolating correlation energies from double-ζ/triple-ζ (DZ/TZ) levels to the complete basis set (CBS) limit remains challen...

Existence and Hausdorff convergence of sliding phenomena in traveling waves for a fast-slow Keller-Segel equation

A one-dimensional Keller-Segel equation with a piecewise-defined reaction term depending on the density gradient gives rise to a nonsmooth fast-slow system. Using Filippov convexification and geometric singular perturbation theory, we prove the existence of sliding traveling wave...

Moral and perceptual conflict processing are implemented by distinct brain activation and functional connectivity patterns

While humans resemble other primates in terms of motor and perceptual abilities, our behavior is uniquely characterized by morality—the ability to choose our actions based on specific ethical values. The evolutionary origins and neurobiological basis of moral behavior are debated...

Information, goal setting and performance: Experimental evidence

We investigate how information about relative performance shapes goal setting and subsequent performance. Combining a field experiment in a university course with a complementary laboratory experiment, we exogenously vary whether individuals receive baseline relative-performance...

The Impact of Infectious Disease Severity on Stigma Associated With Affected Regions: A Facial Representation Perspective

ABSTRACT Individuals from regions affected by infectious disease outbreaks may be stigmatized because others hold negative mental images—or mental representations—of them. This study investigated whether such outbreaks lead to the formation of negative mental representations of r...

Dust Loading Increases During Topsoil Flash Droughts Under Rapid Surface Drying and Vegetation Stress

Abstract Using satellite‐derived dust optical depth (DOD), reanalysis meteorology, and a global topsoil flash drought (TSFD) inventory for 2003–2022, we find that TSFD events are associated with increased dust loading at the global scale. During TSFD events, 44.7% of land pixels...

Identifying recreation priority development zones in global wetland cities under wetland conservation considerations

Balancing recreation and wetland conservation requires identifying where recreational opportunities can be developed with limited ecological disturbance. Taking 43 globally Ramsar-certified Wetland Cities as the study area, this study integrates multi-source remote-sensing and ge...

Neural dynamics of reconstructing knowledge structure from temporally disordered inputs

Humans possess a remarkable ability to integrate fragmented experiences into coherent internal models. However, the neural dynamics supporting structure reconstruction from temporally disordered inputs remain poorly understood. Here, we show that knowledge reconstruction follows...

FCoral: A Framework for Fine-grained Concurrency Evaluation Across Programming Language Runtimes

Modern programming languages increasingly support lightweight concurrency abstractions (e.g., coroutines), which are managed by language-level runtimes to improve scalability and performance in highly concurrent applications. Compared with coarse-grained thread-level concurrency,...

The relationships among achievement motivation health related physical fitness and academic procrastination in adolescents from a multitheoretical perspective

Academic procrastination among adolescents is a complex phenomenon associated with multiple factors. This study aimed to examine the associations among achievement motivation, health-related physical fitness, and academic procrastination in adolescents. A cross-sectional study de...

Clifford Disentanglers for Entanglement Reduction in Molecular Electronic Structure Simulations

Abstract Entanglement is a key bottleneck limiting the efficiency of tensor-network and quantum simulations of molecular electronic structure. Here, we systematically assess and extend Clifford disentanglers as a structure-preserving approach to entanglement reduction: they can m...
