Markerless motion capture-based machine learning models for low back pain classification: a proof of concept investigation

Low back pain affects up to 70% of individuals globally, posing significant health and economic challenges. Traditional methods for classifying low back pain, including radiological imaging and functional tests, are limited by the substantial costs and limited utility via radiolo...

Local Fréchet Regression With Toroidal Predictors

ABSTRACT We provide the first regression framework that simultaneously accommodates responses taking values in a general metric space and predictors lying on a general torus. We propose intrinsic local constant and local linear estimators that respect the underlying geometries of...

Assessing 3D shape cognition using BVH-based hierarchical geometric disclosure

Assessing human 3D shape cognition in a controlled and quantifiable manner remains challenging, as existing approaches often rely on visual cues influenced by prior experience. We introduce a geometry-based experimental paradigm in which 3D objects are progressively disclosed usi...

The loss of COP1 delays senescence and inhibits root growth through modulation of sucrose allocation and availability.

CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) participates in diverse signaling pathways that regulate plant growth and development, but its role in sucrose-mediated signaling remains unclear. Here, we show that COP1 contributes to leaf senescence and root growth by modulating sucrose a...

Composition Engineering of Mn-Based Disordered Rocksalt for Understanding Electrode Degradation Behavior

Cation-disordered rocksalt (DRX) cathodes have emerged as promising candidates owing to their high theoretical capacity and use of earth-abundant transition metals (TMs), such as Mn, Ti, and Fe. Li+ transport occurs through a three-dimensional percolation network of 0-TM diffusio...

Soil-transmitted helminthiasis prevalence and infection intensity among school-going children in Timor-Leste after the prolonged interruption of deworming: a cross-sectional survey (2025)

Background Timor-Leste reduced soil-transmitted helminth (STH) prevalence from 29% to 18% by 2020 through mass drug administration (MDA) in 2015–2019. School-based deworming was interrupted for nearly four years during the COVID-19 pandemic and resumed in 2022 in 3 municipalities...

Physics-informed lithium-ion battery end-of-life prediction model for data-efficient deployment

Accurate prediction of the end-of-life (EOL) is essential for safe and efficient deployment of lithium-ion batteries. While numerous models have been proposed for such prediction, they mostly rely on either extensive cycling data or refined health indices which are difficult to o...

Symptom-Based Hospitalization Risk Differs Between Ulcerative Colitis and Crohn’s Disease: A Nationwide Emergency Department Study

Presenting symptoms guide emergency department (ED) triage and admission decisions in inflammatory bowel disease (IBD), but whether symptoms have similar predictive value in ulcerative colitis (UC) and Crohn’s disease (CD) remains unclear. We examined disease-specific association...

Fast Electronic Memristors with Improved Retention and Synaptic Functionality Enabled by Tri-TaOx Engineering

Artificial synaptic memristors require fast switching, stable retention, low variability, and linear conductance modulation, but achieving these properties simultaneously is difficult in electronic bipolar resistive switching (e-BRS) devices. In this study, a tri-TaOx memristor i...

Stacking Offset Significantly Enhances the Magnetic-Field Modulation of Charge Transfer Spin States in Isomeric Organic Crystals

Abstract Organic functional crystals with specific responses to external stimuli have attracted increasing interest for applications in biomedicine, information encryption, and sensing technologies. Modulating the offset of intermolecular provides an effective strategy for design...

Optimizing the Hinge Length of Chimeric Antigen Receptor with a DdFP-Based Immunological Synapse Biosensor

Abstract Chimeric antigen receptor (CAR)-T cell therapy has emerged as a transformative cancer immunotherapy, employing genetic engineering to express CARs in patient T cells. CARs are composed of a single-chain variable fragment (scFv), hinge, transmembrane, and intracellular si...

International variation in neuropsychological test use practices: Implications for test adaptation and fair assessment

Neuropsychological test selection varies substantially across countries and languages, yet which instruments clinicians use internationally remains poorly documented. Using a survey of International Neuropsychological Society members (INSConnect, 2023), we examined instrument end...

Host-specific effects of a pandemic H1N1 M gene on canine H3N2 influenza virus replication and immune responses

Abstract The emergence of novel influenza strains through reverse-zoonotic transmission poses potential risks to both animal and human health. This study characterized a naturally isolated reassortant canine H3N2 virus carrying the matrix (M) gene of 2009 pandemic H1N1 virus. In...

Layer-by-Layer Electrode Design Integrating a Macroporous Carbon-Nanotube Skeleton for an Anion-Exchange Membrane Water Electrolyzer

Abstract Three-dimensional porous electrodes (anodes and cathodes) using only non-noble-metal electrocatalysts are important for enhancing the performance of anion-exchange membrane water electrolysis (AEMWE), contributing to reduced green-hydrogen production costs. This study de...

Radiative cooling: a decade of progress and the decade ahead

Abstract The accelerating rise in global temperatures and growing demand for cooling underscore the urgent need for sustainable thermal management solutions. Conventional cooling systems depend on energy-intensive processes and refrigerants that exacerbate atmospheric warming, cr...

PLLA–ZnO nanowire nano-vaccine orchestrates balanced Th1/Th2 immunity and confers prophylactic antitumor protection

Cancer vaccines require both cellular and humoral immunity for optimal therapeutic efficacy. We previously demonstrated that carcinoembryonic antigen (CEA)-coated poly- l -lactic acid-zinc oxide (PLLA-ZnO) nanocomposites induce strong cellular immunity and therapeutic antitumor e...

Understanding auto-photography in coaching research: A reflexive account

Drawing upon auto-photography as a research method, this article offers a reflexive account of how the visual method was negotiated and analysed with participants in a study of sport coaching in a semi-professional football club in the UK. When engaging with Henri Lefebvre’s (199...

Toward AI Virtual Cells for Hepatology: Representation, Generation, Dynamics, and Intervention in Single-Cell Models

``Single-cell and spatial atlases describe the healthy and diseased liver at high resolution, including lobular hepatocyte zonation, fibrotic macrophage-stellate niches, cholangiocyte reactions, immune remodeling, and hepatocellular carcinoma ecosystems. These maps show where cel...

Association of oral health with incident pancreatic cancer among individuals with atrial fibrillation: a population-based cohort study

Modifiable factors associated with pancreatic cancer risk in atrial fibrillation (AF) populations remain poorly defined. We aimed to evaluate the associations of oral health status and oral hygiene behaviors with incident pancreatic cancer in individuals with AF. Using the Korean...

Avoid wasted annotation costs in open-set active learning with pre-trained vision–language model

Active learning (AL) aims to improve model performance by selectively collecting highly informative data and reducing annotation costs. In practice, however, unlabeled data may include out-of-distribution (OOD) samples that are not used for training, which can lead to wasted anno...
