Indication of stochastic photothermal dynamics around a topological defect in a chiral magnet

Chiral magnets host topologically protected spin textures whose nonequilibrium dynamics are crucial in phase transitions and domain evolution, yet ultrafast defect-mediated processes remain poorly understood. Here, we investigate a photothermally induced helical-to-paramagnetic p...

B lur D riving : Investigating How Personalized Blur Techniques Impact Drivers' Performance in Virtual Reality

Distracted driving remains a major safety concern, motivating approaches that aim to reduce visual overload before attention breaks down. However, visual overload varies across individuals, making it difficult to determine appropriate interventions for each driver. We investigate...

Two Modes of Reflection: How Temporal, Spatial, and Social Distances Affect Reflective Writing in Family Caregiving

Therapeutic writing offers significant benefits for well-being; however, for family caregivers, conventional fixed or user-initiated schedules often fail to align with their dynamic, high-stress reality. We conducted a three-week field study with 47 caregivers using a chatbot tha...

Resistance as climate change mitigation: Contested emissions from Japan's anti-coal movement

Grassroots resistance increasingly shapes sustainability transformations, yet its implications for climate change mitigation remain difficult to identify and quantify. This paper introduces the concept of ‘contested emissions’ to make visible the climate significance of such stru...

Central visual field defect patterns and progression in glaucoma: a multicentre 10-year study

Background/aims To determine whether baseline central visual field defect (CVFD) distribution and archetypal 10–2 patterns are associated with subsequent central visual field (VF) progression in glaucoma. Methods This retrospective multicentre longitudinal cohort included 127 eye...

Impact of third-party accreditation and general medicine in-training examination participation on residency program popularity: a nationwide matching data analysis in Japan

Abstract Background Third-party accreditation and the visibility of educational outcomes may influence medical students’ choice of training sites; however, national evidence of their effect in Japan is limited. This study examined whether hospital characteristics—especially Japan...

Substrate tuning of the structural and electronic transition in thin flakes of the excitonic insulator candidate Ta2NiSe5

Abstract Ta 2 NiSe 5 continues to draw interest for its T c = 326 K phase transition, whose dual electronic and structural nature reflects a complex interplay of electron-hole (excitonic) and electron-lattice interactions. The majority of studies that have attempted to decipher t...

A Well-Being-Centric Walkable Tourism Platform Using AI Agent

We propose a Well-Being-Centric Walkable Tourism Platform Using AI Agent that fuses heterogeneous urban data—an OSM pedestrian graph, a city-scale microclimate field, and a walkability layer for Sofia, Bulgaria—with an AI agent that converts freetext user requests into a constrai...

Hydrogen-bonded supramolecular assembly of didodecylmelamine and thymine at the air/water interface studied by heterodyne-detected vibrational sum frequency generation

Langmuir monolayers of didodecylmelamine (2C12mela) on thymine aqueous solutions were studied by in situ heterodyne-detected vibrational sum frequency generation (HD-VSFG) spectroscopy. The HD-VSFG spectrum of the monolayer on a 10 mM thymine aqueous solution exhibited a positive...

Evaluating a service-learning program: benefits of integrating medical students into school cancer education on teaching skills and cancer knowledge

Abstract Background Integrating medical students into school cancer education programs as service-learning is a promising strategy. This study assessed the impact of such programs and evaluated their effectiveness in improving students’ teaching self-efficacy and understanding of...

Interpretable substructure-based screening of multi-property polymer dielectrics with prompt-ready rules for rational design

Abstract High-performance polymer dielectrics remain difficult to discover because transparent connections between molecular substructures and macroscopic properties are lacking. Existing machine-learning approaches often rely on black-box representations that obscure the chemica...

Connections between the Föllmer process and the denoising diffusion probabilistic model

Abstract The Föllmer process is a Brownian motion conditioned to have a pre-specified distribution at time 1. This process can be interpreted as an “augmented” time-compressed version of the reverse stochastic differential equation (SDE) corresponding to the denoising diffusion p...

Gamma-ray signatures of thermal misalignment dark matter

A bstract Thermal misalignment is a viable dark matter scenario where the misalignment of a dark matter scalar, feebly coupled to the Standard Model particles, is generated through thermal effects from the primordial plasma. In this framework, the scalar is generically metastable...

Pharmacological management of knee and hip osteoarthritis stratified by oral nonsteroidal anti-inflammatory drugs safety status

INTRODUCTION: Knee and hip osteoarthritis are treated with oral nonsteroidal anti-inflammatory drugs (NSAIDs); however, pharmacological management by NSAID safety status remains unclear. We characterized pharmacological treatment patterns across safety strata. MATERIALS AND METHO...

World model for robot learning: A comprehensive survey

World models, which are predictive representations of how environments evolve under actions, have become a central component of robot learning. They support policy learning, planning, simulation, evaluation, data generation, and have advanced rapidly with the rise of foundation m...

Nanopore-Induced Thickness Independence of In-Plane Thermal Transport in Few-Layer Graphitic Carbon Nitride

Abstract Although in-plane thermal transport in many two-dimensional (2D) materials exhibits pronounced thickness dependence, it remains unclear whether this behavior persists in intrinsically porous 2D systems. In this work, we employ a scalable, high-accuracy atomistic simulati...

Dabrafenib plus trametinib in BRAF V600E-mutant Erdheim–Chester disease: a case series including CNS involvement

Abstract Background Erdheim–Chester disease (ECD) is a rare clonal non-Langerhans cell histiocytosis characterized by the infiltration of foamy, CD68-positive/CD1a-negative histiocytes into multiple organ systems. Activating MAPK/ERK pathway mutations, most commonly BRAF V600E, r...

From Instruction to Inheritance: Scaling Robot Learning Through Knowledge Circulation

Robot learning, particularly through vision–language–action (VLA) models, has rapidly improved the ability of robots to execute instructed tasks. However, the current mainstream paradigm of robot learning largely depends on one‐way instruction from humans to robots, lacking a cyc...

Phase-Programmed Charge Routing Governs Kinetic and Thermodynamic Molecular Selectivity for Chemiresistive Sensors

Abstract Controlling molecular selectivity in chemiresistive gas sensors remains a fundamental challenge, particularly for chemically analogous analytes that generate indistinguishable electronic responses. Here, we demonstrate that polymorph-engineered MoS2/SnO2 heterointerfaces...

A repurposed pseudoenzyme enables redox- and acetylation-dependent control of CoA transferase

CoA transferases play essential roles in short-chain fatty acid and acyl-CoA metabolism, yet how their activities are regulated in response to metabolic signals remains unclear. Here, we show that a CoA transferase from Thermus thermophilus is controlled by a two-layer mechanism...
