Near-Surface Temperature Biases in Regional Climate Models over Complex Orography: A Physically Grounded Diagnosis

Regional climate models (RCMs) remain affected by limited spatial resolution and systematic biases relative to observations, posing a major challenge for the provision of actionable climate information at the local scale. Bridging the gap between coarse, biased model outputs and...

Stable biomass accumulation driven by conservative traits in Brazil’s tropical montane forests

While tropical forests are key CO2 sinks, local drivers of aboveground biomass (AGB) dynamics in diverse systems like the Brazilian Atlantic Forest remain uncertain, constraining ecological references for restoration and long-term carbon sequestration. This study evaluates how bi...

Crack-localization in elastomeric self-healing enabled by one supermolecule-analogous molecule

Residual invisible cracks make perfect material self-healing difficult to achieve. In principle, cracks could be visualized by luminescent indicators; however, high-energy fluctuations associated with rapid healing kinetics interfere with the electronic transitions of luminophore...

COVID-19-Related Knowledge and Health Literacy Among Village Heads (Muhtars) and Their Relatıves: A Pre-Test–Post-Test Study

Objective: This study aimed to evaluate COVID-19-related knowledge and health literacy levels among village heads and their relatives in the Çarşamba district of Samsun, Türkiye, and to assess the effectiveness of a structured educational intervention.Methods: This descriptive st...

Vinylene‐Linked Covalent Organic Frameworks With Multi‐Intramolecular Coupling‐Promoted Photocatalytic CO 2 ‐to‐CO Conversion

ABSTRACT Covalent organic frameworks (COFs) offer significant potential for solar energy conversion, but their sluggish intrinsic charge‐transfer kinetics inherently restrict the activation of stable CO 2 . Herein, we developed a new electron‐deficient monomer 6,6′‐dimethyl‐3,3′‐...

Adaptive Spatial–Frequency Information Fusion for SAR Ship Detection

Synthetic-aperture radar (SAR) ship detection is a fundamental task in maritime remote sensing, supporting wide-area surveillance, traffic monitoring, and emergency response under all-weather imaging conditions. Existing deep detectors mainly rely on spatial cues such as intensit...

Image segmentation method with improved boa and scheduling processing

Image segmentation is a key step in image processing and analysis. However, traditional segmentation methods suffer from slow convergence and low segmentation accuracy. Deep learning methods, such as mask region-based convolutional neural networks, can segment medical images with...

Analytical and symbolic characterization of nonlinear dynamics for a class of energy supply demand system versus time delay

This paper investigates the nonlinear dynamic behavior of a three-dimensional energy supply–demand system with government regulation and time delay. A mathematical model is first established. By employing the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inlin...

Sexual Behaviors and Reproductive Responsibility Among Young Black Men at an HBCU: A Qualitative Study

Sexual and reproductive health research has often centered women’s contraceptive and pregnancy-related experiences, while young men’s perspectives on sexual behavior, STI prevention, and reproductive responsibility remain less visible. This qualitative study explored how young Bl...

Meaning in Religious Contexts: Examining Beliefs in Free Will and Determinism (or Divine Sovereignty and/or Providence) as Christian Meaning Frameworks With Religious Commitment as Moderator in a Moderated Mediation Model

This study examined the associations among beliefs in free will and determinism (or divine sovereignty and/or providence), meaning in life (MIL), and meaning judgment, as well as whether religious commitment moderates these associations. Guided by the Tripartite Meaning in Life M...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

Origami-inspired robotic grippers have shown promising potential for object manipulation tasks due to their compact volume and mechanical flexibility. However, robust capture of objects with random shapes in dynamic working environments often comes at the cost of additional actua...

Recent Advances in Comprehending Endothelial Dysfunction and Diabetic Cardiomyopathy: From Molecular Mechanisms to Clinical Applications

Diabetic cardiomyopathy (DCM) is a cardiac condition characterized by various structural and functional abnormalities that are associated with diabetes mellitus. Its development involves multiple factors, among which endothelial dysfunction plays a significant role. To fully desc...

Ethics in the crossfire: politicised patient care, cultural authority, and nurses’ constrained moral agency

Abstract Background Socio-political polarisation increasingly shapes health decisions and clinical encounters, yet little is known about how nurses in low- and middle-income countries navigate conflicts among formal patient rights, family authority, cultural obligations, and poli...

Analytical performance evaluation of commercially available hepatitis A virus IgM immunoassays: ELISA, ICTs, and chemiluminescence immunoassay

Objectives: The objective of the study is to evaluate the diagnostic performance of commercially available hepatitis A virus (HAV) immunoglobulin M (IgM) index tests, specifically enzyme-linked immunosorbent assays (ELISA) and rapid immunochromatographic tests (ICTs), against a c...

Population turnover and food-web reorganization sustain acetoclastic methanogenesis at 45 °C in tropical paddy soil

Moderately thermophilic temperatures (45 °C) are widely expected to suppress acetoclastic methanogenesis in paddy soils because thermodynamic constraints favor syntrophic acetate oxidation coupled with hydrogenotrophic pathways. However, tropical paddy soils often deviate from th...

Real-Time Vision-Based Fall Detection Systems for the Elderly: A Systematic Review

Falls represent a threat to older adults, overload healthcare systems, and reduce quality of life. Vision-based fall detection has advanced recently through deep learning, yet most proposed models lack validation on physical hardware and do not report inference-time metrics. This...

How Healthy Are Community Health Workers: Findings from a Chicago-Area Survey

Community health workers (CHWs) are a growing and essential component of the U.S. healthcare workforce, yet little is known about their own health and well-being. The CHWs Our Work + Our Health Pilot Study administered a cross-sectional survey to a convenience sample of CHWs livi...
