Bio-hydrophilic chain extenders with amphiphilic character for waterborne polyurethane derived from castor oil/tea seed oil: separation, synthesis, and application

Unsaturated vegetable fatty acids, as a renewable resource, are abundantly present in vegetable oils, exhibiting significant potential for the synthesis of bio-polyols and bio-based polyurethanes (PUs). Herein, castor oil (CO) and tea seed oil (TSO) were selected as feedstocks to...

Strabismus-Net mobile application for nine-gaze photograph-based strabismus diagnosis using dual-stream cross-attention and adaptive feature aggregation

Early detection and intervention of strabismus are crucial for effective treatment, yet traditional diagnostic methods require extensive expertise, often causing diagnostic delays in underserved areas. In this study, we propose and validate a “two-tier” stratified diagnostic syst...

Multistage analysis of quality in pit-and-fissure sealant programs for first permanent molars: a real-world study

This study examined the associations of operator routine procedural exposure and children’s residential setting (urban vs. rural) with quality indicators across three stages—diagnostic attribution, operational execution, and long-term retention—in a pit-and-fissure sealant progra...

Continuous Heterodyne Microwave Sensing With van der Waals Spin Defects

ABSTRACT Quantum sensing with solid‐state spin defects provides a powerful approach for microwave‐field detection, but conventional sensing protocols are often limited by narrow detection bandwidths. Here, we demonstrate continuous heterodyne microwave sensing using spin defects...

Bias‐Free Tactile Synaptic Ionogel With Viscoelastic Memory for Biomechanical Monitoring

ABSTRACT Endowing artificial skins with adaptation and sensory memory is essential for intelligent tactile perception. However, conventional transistor‐based neuromorphic systems rely on energy‐intensive, decoupled architectures that fundamentally constrain their structural flexi...

Ultrasound-defined hepatic steatosis and clustering of cardiometabolic abnormalities: endpoint-dependent performance of seven metabolic indices in 356,197 adults

Hepatic steatosis commonly coexists with cardiometabolic abnormalities, but the extent to which an ultrasound finding identifies their clustering in routine health-examination populations remains unclear. We quantified the association between hepatic steatosis and cardiometabolic...

Astragaloside IV improves MASLD via GCN5-LXRα/SREBP1c signaling pathway-mediated hepatic de novo lipogenesis

BACKGROUND: Astragaloside IV (AS-IV), a bioactive saponin from Astragalus membranaceus, shows promise for treating metabolic dysfunction-associated steatotic liver disease (MASLD), though its mechanisms remain unclear. PURPOSE: This study aimed to elucidate how AS-IV alleviates h...

AI-Assisted Speaking Practice and Human-Directed Communicative Readiness: Survey and Scenario Evidence on Anxiety, Self-Efficacy, and Evaluation Pressure

Generative artificial intelligence (GenAI) voice tools create low-risk opportunities for second-language (L2) speaking practice, but it remains unclear whether AI-assisted speaking practice is associated with human-directed communicative readiness and how this relationship varies...

A Resilience Enhancement Method for Distribution Networks Under Extreme-Event Scenarios Considering Flexible Interconnection via Energy Routers

An energy router (ER), featuring flexible multi-port access, bidirectional power regulation, and cross-regional energy exchange, provides versatile control capabilities for fault isolation, critical-load supply, and post-disaster restoration in distribution networks under extreme...

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

ABSTRACT 3D bioprinting is known for its high precision and reproducibility in fabricating complex and customized biomedical constructs. However, its applications are limited by their static nature; i.e., unlike native tissues, they cannot change shape or functionality over time....

Raised to Relate: How Parenting Quality Is Associated With Citizenship and Deviance at Work?

ABSTRACT Objective This study examined whether perceived moral awareness (PMA) and perceived empathic concern (PEC) explain associations between parenting quality (PQ) and workplace behaviors, namely organizational citizenship behavior toward individuals (OCBI) and interpersonal...

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

ABSTRACT To overcome the poor bioavailability and environmental instability of physical polyphenol co‐assemblies while maximizing their preventive efficacy, the authors engineered carrier‐free, metal–phenolic coordination nanoparticles (ZnCA NPs) utilizing divalent zinc (Zn 2+ )...

The Host‐Guest Assemblies of Metal–Organic Frameworks and Protic Ionic Liquids With ZIF‐8 and [Dema][TfO] – Structural Response and Ionic Conductivity

ABSTRACT The synergy between ionic liquids (ILs) and metal–organic frameworks (MOFs) has attracted considerable attention because of future applications as a tailor‐made hybrid ionic conductor. The incorporation of ILs into MOFs cages has led to the development of a novel type of...

Freeze–thaw-induced evolution of erosion mechanisms in cementitious materials under high-altitude environments

Concrete hydraulic structures in cold, high-altitude regions are subjected to coupled freeze–thaw deterioration and sediment-laden flows, leading to progressive surface degradation. However, the influence of freeze–thaw damage on the governing erosion mechanism remains poorly und...

Hierarchical microbial distribution organized by ordered river structure explains why GHG emission favors small streams

In river networks, small streams usually emit the largest proportion of greenhouse-gases (GHGs). However, the associated microbial mechanisms affected by the hierarchy of river systems are unclear. To address this, we measured N 2 O, CH 4 and CO 2 fluxes at 22 sites selected from...

Early-life famine exposure and advanced cardiovascular-kidney-metabolic syndrome in Chinese adults: an apparent critical window explained by a birth-cohort gradient

Abstract Background Famine studies repeatedly report window-specific effects on adult disease risk, but because exposure windows are defined by date of birth, window-specific estimates are structurally confounded by birth cohort and by chronological age. We examined whether expos...

Tightly Coupled FeNi Alloy/NiO Interface Derived from an LDH Precursor Promotes Deep Hydrodeoxygenation of p -Cresol

Abstract Hydrodeoxygenation (HDO) of lignin derivatives is a promising strategy for biomass utilization, but its catalytic performance is often unsatisfactory for non-noble metal catalysts. This hinders the industrialization process of biomass utilization. Herein, we obtained a F...

Unexplained intra-abdominal hemorrhage: a case report and literature review

Spontaneous intra-abdominal hemorrhage is a life-threatening emergency with high mortality, often linked to vascular pathologies or visceral organ rupture. This case report details a rare instance of recurrent hemorrhage and reviews etiological insights. A 72-year-old hypertensiv...

Study on the impact of meditation intervention on the white matter structure in schizophrenia

Schizophrenia is associated with abnormal white matter structural connectivity, and meditation has been investigated as an adjunctive intervention for clinical symptoms. This study examined whether an 8-month meditation intervention was associated with longitudinal changes in cli...

Floor response spectra–oriented acceleration mitigation of base-isolated structures with rate-independent damping

Engineering structures accommodating acceleration-sensitive non-structural equipment exhibit an intrinsic incompatibility in seismic demand control, as base isolation effectively suppresses inter-story drift, whereas the introduction of linear viscous dampers to restrain isolator...
