Non-concussive head impacts sustained during American football correlate with changes in gut microbiome diversity and composition
Non-concussive head impacts (NHIs) are a significant health concern among at-risk groups, including athletes and military personnel. NHIs are hits to the head or head acceleration events (HAEs) that do not generate clinically detectable symptoms and are unlikely to meet diagnostic criteria for mild…

A citizen scientist’s survey provides insights into the movements of Atlantic and Gulf states’ populations of Black Skimmers ( Rynchops niger )
Ornithologists are increasingly using field readable bands—plastic rings with alphanumeric codes that are visible from a distance—to study bird populations. Because of this advance, a member of the public can now readily engage in research. On one level, such a citizen scientist can report hundreds…

Predicting corporate management performance using AI: Incorporating CEO strategy insights from sustainable management reports
This study proposes an AI-based model to predict corporate management performance by combining financial data with strategic information extracted from CEO messages in sustainability reports. Using a dataset of 1,271 listed companies on Korea’s KOSPI and KOSDAQ markets (2016–2023), we applied eight…

Machine learning-based unified models for predicting drug clearance from pharmacokinetic animal and study design variables
Clearance (CL) is a primary pharmacokinetic (PK) parameter crucial to determine how quickly a drug is eliminated from the body, which guides the appropriate dosing interval to maintain a consistent concentration in blood. Given the importance of CL, this study aimed to use machine learning (ML)…

ScaleDefrag: Design and implementation of a scalable file defragmentation tool for flash-based SSDs
We propose ScaleDefrag, a parallel and asynchronous defragmentation tool that reduces defragmentation time by up to 3.8× compared to e4defrag, while improving scalability on multi-core systems. Flash-based solid-state drives (SSDs) have been widely adopted in various large-scale storage systems…

AOW-YOLO: An efficient and lightweight model for smoking behavior detection on construction sites
We propose AOW-YOLO, a novel model designed to address the challenge of detecting smoking behavior in complex construction site environments, which is particularly difficult due to the typically small size of objects and cluttered backgrounds. AOW-YOLO is built upon YOLO11n through the following…

Surface anticoagulation of mechanical heart valves using electrically induced biomimetic glycocalyx: An in-vitro study to assess hemocompatibility and optimal voltage
Mechanical heart valves (MHVs) remain the most durable option for valve replacement, but they are highly thrombogenic and therefore necessitate life-long anticoagulation. We designed a novel MHV assembly based on “Surface Anticoagulation by Electrically induced Biomimetic Glycocalyx” (SAEBG) that…

Physicochemical, spectral, medicinal, and toxicological studies of Ketoprofen, Ibuprofen, and their major degradants: A quantum-chemical and in silico approach
Nonsteroidal Anti-inflammatory drugs (NSAIDs) are significantly consumed all over the world to treat pain, inflammation, and fever. Despite their ability to reduce pain and inflammation, they and their degradants can be toxic to both human organisms and the environment. This in-silico investigation…

Climatic niche properties shape treefrog diversity
A suite of ecological hypotheses has been proposed to explain why more species are found in the tropics. Most of these hypotheses consider the geography of climate as a major determinant of richness, while ignoring the relationships between organisms and climate, in other words, their climatic…
