Self-reported sports participation is associated with Y-Balance performance and centre-of-pressure measures in young adults

Abstract This exploratory cross-sectional study examined associations between a study-specific self-reported sports-participation category and balance measures in 65 healthy young adults, including 32 participants in the sports-participation group and 33 in the non-sports-partici...

Mortality and morbidity consequences of particulate matter in South Korea: evidence from transboundary air pollution

Abstract Background: Exposure to fine particulate matter (PM 2.5 ) is harmful to people, leading to respiratory disease and even death. The association between PM 2.5 pollution and health outcomes has become a key foundation for public health policy development. This study aims t...

Targeting the Candida albicans agglutinin-like sequence 3 adhesin to disrupt oral polymicrobial bacterial–fungal biofilms: mechanisms and therapeutic strategies

glucosyltransferases is examined in detail. Emergent properties of Als3-dependent oral co-biofilms, including elevated antimicrobial tolerance, architectural complexity, metabolic interdependence, and interkingdom signaling amplification, are analyzed. Therapeutic strategies revi...

Unravelling the Atomic‐Scale Surface Chemistry for Intrinsically Bright and Stable Luminescence in CdSe Quantum Platelets

Two-dimensional colloidal CdSe quantum platelets (QPLs) represent a promising class of next-generation luminescent materials, yet the atomic-level surface chemistry that governs their optoelectronic properties remains poorly understood. In this study, we combine ligand passivatio...

Directionally Aligned, Defect-Suppressed Non-oxidatively Exfoliated Graphene Flakes for High EMI Shielding Performance

Abstract In this study, we report the development of high-performance electromagnetic interference (EMI) shielding composites incorporating directionally aligned non-oxidatively exfoliated graphene flakes (NOGF) within a polydimethylsiloxane (PDMS) matrix. The NOGF was synthesize...

Shedding Kinetics and Infection Stage-Dependent Horizontal Transmission of Infectious Spleen and Kidney Necrosis Virus (ISKNV) in Angelfish (Pterophyllum scalare)

Infectious spleen and kidney necrosis virus (ISKNV), a member of the genus Megalocytivirus, threatens ornamental and farmed aquaculture because of its broad host range and environmental persistence. This study investigated ISKNV infection dynamics and stage-dependent horizontal t...

An h-likelihood approach to fitting accelerated failure time models for clustered heavily censored data

Motivated by oral health time-to-event outcomes, we focus on the analysis of clustered (tooth within subjects), heavily right-censored, survival data, where the event of interest is tooth failure. The generalized extreme value (GEV) distribution is widely used for analyzing extre...

Deep learning-based burned area mapping of California wildfires using Sentinel-2 and Landsat-8 imagery enhanced with super-resolution techniques

The increasing frequency of wildfires under a changing climate has led to extensive ecosystem destruction, highlighting the need for reliable burned area assessment using satellite imagery. Single-satellite data are constrained by observation gaps and interference from smoke and...

Feasibility Assessment of SAM-Assisted Pseudo-Oriented Bounding Box Generation from Ship Point Annotations in KOMPSAT-3/3A Optical Satellite Imagery

Satellite-image-based ship detection is important for maritime traffic management, search and rescue, illegal fishing surveillance, and maritime security.However, constructing oriented bounding box (OBB) annotations requires manual delineation and verification of object boundarie...

Data-driven enhancement of ocean surface forcing for accurate floating debris transport modelling in the East/Japan Sea

Abstract. Floating debris transport in marginal seas is controlled by a combination of geostrophic currents, wind-driven currents, wave-induced drift, and direct wind forcing, but the relative importance of these processes remains difficult to quantify without in-situ trajectory...

Coffee brewing trajectories from recipe-level records: a conservation-constrained framework for filter coffee

Abstract Filter coffee recipes specify brewing operations and selected beverage outcomes but do not resolve the extraction trajectory within the coffee bed. Here, we develop a reduced-order, conservation-constrained framework that reconstructs conditional water and dissolved-soli...

Hydrodynamic Implications of Levee Breach Width Variation on Turbulence Structures and Discharge Efficiency

Abstract This study investigates the effects of levee breach width on flow and turbulence structures, as well as on the discharge coefficient, under river-type flow conditions using the open-source computational fluid dynamics (CFD) software OpenFOAM. A three-dimensional (3D) Rey...

Field-Deployable Paper-Based Detection of Vibrio vulnificus via Mechanically Automated Sequential RPA/CRISPR-Cas12a

Vibrio vulnificus (V. vulnificus) is a highly virulent marine pathogen that causes severe infections, including sepsis and necrotizing fasciitis, with high fatality rates in susceptible individuals. Rapid and sensitive on-site detection is therefore essential, yet existing method...

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

ABSTRACT Photodetectors sensitive to the near‐infrared (NIR) range are of great importance for applications in machine vision, autonomous driving, and three‐dimensional (3D) imaging under low‐light or adverse weather conditions. Recently, two‐dimensional (2D) semiconductors have...
