Quantum-well metasurface for free-space-accessible enhanced nonlinear polarization

Abstract Nonlinear frequency conversion underpins important technologies such as telecommunications and quantum computation; however, weak nonlinearities and architectures that resist miniaturization currently limit devices’ efficiency and widespread adoption. Here we combine a b...

Robust inference and correlates from genetic associations with personality

Personality traits describe stable differences in how people think, feel and behave, and how they interact with and experience their social and physical environments1,2. Many questions remain unanswered about associations between DNA and personality traits, such as their robustne...

Sex Bias in the Clinical Diagnosis of ADHD: A Critical Review

Background: Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder that manifests differently across sexes, potentially impacting symptomatology, diagnosis, and treatment. Nevertheless, these legitimate sex differences in ADHD are further shape...

Experimental and Machine Learning‐Based Parametric Study of Free‐Bending Dielectric Elastomer Actuators

Recent advances in electroactive polymers and smart materials have established dielectric elastomer actuators (DEAs) as a viable platform for lightweight, large‐deformation soft actuation. This study presents a parametric investigation of dielectric elastomer bending actuators, f...

Exploring the mediating role of working alliance in a peer support intervention for late-life depression

Objective: Peer support is an evidence-based intervention for depression, yet the mechanisms underlying its effectiveness remain understudied, particularly in randomized clinical trials. This study examined the mediating role of working alliance components (task, bond, and goal)...

LACSF framework deployment for fault detection and mitigation

AI-driven failure detection is becoming essential in industrial manufacturing systems where conventional diagnostic methods often fall short in reliability and live feedback. This paper presents the integration of a modular artificial intelligence framework adapted to overcome th...

Topology Optimization for Fracture Resistance using Differentiable Programming and Peridynamics

Abstract Fracture resistance is a critical consideration in engineering structures, particularly in applications where material failure can have catastrophic consequences. Traditional topology optimization methods often struggle to account for fracture propagation due to the inhe...

Benchmark Brown Dwarfs as Chemical Laboratories: Linking System Bulk Properties to Atmospheric Retrievals

Abstract We present the first atmospheric retrieval analysis of two compositional benchmark mid-L dwarfs – SDSSJ141659.78+500626.4 and GJ 499 C – using the Brewster retrieval framework, where the wide benchmark nature of these systems provides independent constraints on age and b...

Bonded Water Is an Integral Component of Dissolved Organic Matter in the Ocean

Abstract Dissolved organic matter (DOM) in the ocean, as one of the largest pools of reduced carbon on Earth, plays an important role in the global carbon cycle, yet its chemical structure remains largely unknown. Here we show that high molecular weight DOM (HMW‐DOM) contains app...

Structure-function analysis of the FCRL5–IgG1 Fc complex reveals an unappreciated pathway for B cell modulation by Fc-attenuated IgG

The Fc region of therapeutic IgG antibodies is often engineered to remove or “silence” Fc effector functions, but it remains unclear whether these mutations eliminate all Fc-mediated effector activity. Human Fc receptor-like 5 (FCRL5/FcRH5) is a low-affinity IgG Fc receptor expre...

Derivation of oligonucleotide barcodes that are absent from natural sequences

Abstract DNA barcodes are short synthetic sequences used to uniquely identify target molecules, samples, or objects, and are essential for a wide range of biotechnology applications including high-throughput sequencing, lineage tracing, genetic screens, massively parallel reporte...

Towards A Universal Analytical Model of Population III Star Formation: A Bridge Between Cosmological Scales and Protostars

Abstract We construct an analytical model of Population III star formation that connects the cosmological radiation background to sub-AU protostellar disk fragmentation, a dynamic range inaccessible to any single simulation. Our approach is based on combining separate models of t...

Forest Kernel Balancing Weights: Outcome‐Guided Features for Causal Inference

While balancing covariates between groups is central for observational causal inference, selecting which features to balance remains a challenging problem. Kernel balancing is a promising approach that first estimates a kernel that captures similarity across units and then balanc...

Hybrid SERS Platforms for Enhanced Biochemical Sensing

Surface-enhanced Raman scattering (SERS) is a powerful analytical technique for label-free, ultrasensitive biochemical detection, offering broad potential for biomedical, environmental monitoring, and defense applications. However, conventional noble-metal SERS substrates remain...

Crimean-Congo hemorrhagic fever virus protein GP38 from isolate M18-China confers broad immunological breadth

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne, negative-strand RNA virus that causes outbreaks of lethal hemorrhagic fever. No approved vaccines or specific antiviral treatments are available. CCHFV glycoprotein GP38 is an integral component of the pre-fusion glyc...

The Impact of Generative AI on Collaborative Open-Source Software Development: Evidence from GitHub Copilot

Generative artificial intelligence (AI) facilitates content production and enhances ideation, with potentially important implications for developer productivity and participation in software development. To explore its impact on collaborative open-source software (OSS) developmen...

Dry-hole analysis of exploratory wells in East Tiba-Natrun Area, NE Abu Gharadig Basin, Western Desert, Egypt: implications to petroleum exploration

Abstract Each non-productive or unsuccessful well is unique, tells its own story, and has distinctive reasons for being classified as a dry hole or lacking sufficient hydrocarbons. The objective of this study is to present a dry-hole analysis of three exploratory wells drilled in...

Multi-resolution enhancement for full-spectrum neural representations

Scientific data acquisition continues to outpace storage and analysis capabilities, making voxel-based representations increasingly intractable. Implicit neural representations (INRs) offer a promising solution by encoding signals through coordinate-based neural networks, serving...

Exercise addiction, social interaction, and the moderating effects of disordered eating among adults aged 18–35

Physical exercise is beneficial to physical health and social well-being. However, with extreme volumes, exercise may lead to addiction symptoms comparable with substance use and gambling disorders. Social dysfunction is a crucial element that constitutes exercise addiction (EA),...

Distinct Neural Signatures of Novel Word–Referent Mapping in Monolingual and Bilingual Toddlers

ABSTRACT Evidence suggests that bilingualism impacts children's lexical and brain development. Yet, the development of the brain's language network in early childhood–a period marked by rapid vocabulary growth–remains poorly understood, particularly with respect to differences be...
