Large language model–assisted scoring of physician-administered parent interviews for autism screening in young children: a retrospective diagnostic case-control and agreement study

Large language models (LLMs) may assist clinicians in scoring narrative parent-report interviews, but diagnostic discrimination, score agreement, output repeatability, and clinical utility are distinct claims. We evaluated an LLM-assisted workflow for scoring a physician-administ...

Training-free post-disaster damage estimation with incomplete satellite images by integrating open data and fractional hot deck imputation

Abstract Analyzing satellite imagery is an essential step after a severe natural disaster for monitoring the level of damage and making the best decision. The current study proposes a fast post-disaster damage framework incorporating the remote sensing of imagery, entropy calcula...

Magnetic graphs for cavity quantum electrodynamics

Strengthening light-matter coupling has become a central challenge in cavity quantum electrodynamics (QED), enabling ultrafast gate operations, qubit protection, and deterministic nonlinear optics. As the coupling increases, even the simplest configuration—an atom interacting wit...

Asymptotic stability and cut-off phenomenon for the underdamped Langevin dynamics

In this article, we provide a detailed analysis of the long-time behavior of the underdamped Langevin dynamics. We first provide a necessary condition guaranteeing that the zero-noise dynamical system converges to its unique attractor. We also observed that this condition is shar...

Dual Effects of β‐TrCP2 Deletion in Bone Homeostasis: Suppression of Osteoclastogenesis and Enhancement of Osteoblast Activity

OBJECTIVES: To elucidate role of beta-transducin repeat-containing protein 2 (β-TrCP2) in bone homeostasis for its potential as a therapeutic target for osteoporosis. METHODS: ) mice. Bone microarchitecture was assessed by micro-computed tomography, and osteoclast and osteoblast...

Seroprevalence of Toxoplasma gondii among animal-associated workers and companion animals in South Korea

Abstract Toxoplasma gondii is a widely distributed zoonotic parasite at the human–animal interface. However, studies simultaneously evaluating animal-associated workers and companion animals remain limited in South Korea. This multi-regional cross-sectional study aimed to estimat...

pH-responsive supramolecular vesicles based on a pillar[5]arene–cuminaldehyde inclusion complex with enhanced antibacterial properties

A pH-responsive delivery system based on supramolecular vesicles was fabricated via a novel host–guest inclusion complex between water-soluble pillar[5]arene (WP5) and cuminaldehyde (CUM). This CUM-WP5 inclusion complex was studied using 1 H NMR, UV-vis, and FT-IR spectroscopy. T...

Ligand-Mediated Control of Zn x Se y Intermediates for Defect-Free ZnSe Heteroepitaxy on Quantum Dots

Abstract ZnSe is a cornerstone shell material for enhancing the efficiency and stability of quantum dots (QDs). However, the chemical mechanisms governing detrimental zinc vacancy (VZn) formation remain unclear, limiting the predictive synthesis of high-quality heterostructures....

Prognostic associations of anthropometric indices with major health outcomes: A nationwide cohort study of 1.1 million adults

Background and Aims The global escalation of obesity necessitates precise tools for assessing diverse health risks. This study aimed to compare the prognostic associations of body mass index (BMI), waist circumference (WC), and the body roundness index (BRI) across multiple cardi...

Personalized deep learning for short-term forecasting of impending atrial fibrillation from continuous wearable ECG signals

Abstract Continuous wearable electrocardiogram (ECG) monitoring is increasingly used for ambulatory arrhythmia surveillance, yet forecasting impending atrial fibrillation (AF) remains challenging because of inter-patient ECG variability. We investigated whether personalizing a gl...

An IMM Extension of RBPMF for Terrain-Referenced Navigation Under Radar Return Ambiguity

Terrain-referenced navigation (TRN) relies on nonlinear terrain matching, which can produce multimodal position uncertainty that should be retained during estimation. Accuracy can deteriorate when the relative probabilities of ground and canopy returns vary over time because a fi...

Exact four-parameter rotating NS-NS vacuum in double field theory

A bstract We construct an exact rotating vacuum of the NS-NS sector, equivalently a Double Field Theory vacuum. The construction applies compact SO (2) S-duality to a rotating Einstein-scalar seed. The solution has four independent parameters $$ \left\{\mathfrak{m},j,\mathfrak{q}...
