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...

Inclined gabion drops improve hydraulic performance relative to conventional USBR stilling basins under variable flow conditions

This study experimentally and numerically investigates the hydraulic performance of the Inclined Gabion Drop (IGD) as a sustainable energy dissipator compared with conventional USBR stilling basins. Laboratory experiments were conducted under varying flow conditions, drop heights...

Privacy-Preserving Ambient Sensing for Activities of Daily Living: Multimodal Radar–Thermal Human Activity Recognition and Smart Plug Appliance Recognition

Continuous monitoring of Activities of daily living (ADLs) requires sensing systems that are privacy-preserving, low-power, and robust to environmental variation. Ambient sensing technologies provide an alternative to RGB video and wearable devices, but individual sensing modalit...

Recent synthetic strategies for N-heterocyclic β-carboline derivatives in drug discovery: chemical and biological perspectives

β-Carboline derivatives are important nitrogen-containing heterocycles widely studied in medicinal chemistry because of their diverse biological activities and flexible chemical properties. This mini-review summarises recent progress reported from 2013 to 2025 in the synthesis an...

Reduction in Nutrients, Fecal Coliform Bacteria, and Antibiotic Concentration in a Constructed Wetland

Constructed wetland has evolved into an effective treatment method of effluent, an important consideration in mitigating the escalating problem of antibiotic resistance in environmental and human health contexts. This study evaluated the performance of a 21-acre horizontal flow c...

Electroantennographic and Behavioral Evidence Identifies Carvone and IR3535 as Biting Deterrents Against Rhodnius prolixus (Stål, 1872)

Electroantennography (EAG) is a valuable approach for monitoring insect antennal responses to insecticidal and test compounds and may provide a preliminary screening method for identifying compounds with potential activity against medically important insect vectors. The objective...

Disentangling the Interplay Among Genetics, Feeding and Production System Characteristics on Methane Emissions in Holstein Friesian Dairy Cows

Methane (CH4) emissions from dairy cattle contribute substantially to agricultural greenhouse gas production and are influenced by genetic, physiological, environmental and management-related factors. The present study investigated CH4-related traits and genotype–system interacti...

NonlinearSynergistic Coupling of Poisson Deformationand Crack Engineering Enables Linear Mechanosensing up to 4 MPa

Abstract Reliable and accurate physiological mechanosensing requires tactile sensors that maintain linearity across ultrawide ranges, yet most reported devices saturate below 500 kPa due to strain hardening and deformation saturation of elastic microstructures. Balancing this lon...

Genomic traits, transcriptional responses, and metabolic activities determine functional divergence in mineral dissolution between Priestia megaterium PMA2-2 and Priestia flexa PMD1-1

ABSTRACT Priestia strains are gram-positive bacteria and globally distributed in mineral-rich environments. However, the functional divergence in mineral dissolution and its molecular drivers among Priestia strains remains poorly understood. Here, we employ comparative phenotypic...
