A Transient Left Atrial Appendage Filling Defect During Anticoagulation Interruption After Ischemic Stroke with Progressive Hemorrhagic Transformation: A Case Report

Background and Clinical Significance: Anticoagulation timing after atrial fibrillation (AF)-related ischemic stroke is uncertain when hemorrhagic transformation (HT) is progressive. Although early direct oral anticoagulant (DOAC) initiation is supported in selected patients, evid...

WACA-UNet: Weakness-Aware Channel Attention for Static IR-drop Prediction

Accurate spatial prediction of power-integrity issues such as IR drop is critical for reliable VLSI design, yet traditional simulation-based solvers do not scale efficiently to modern designs. We formulate static IR drop estimation as a pixel-wise regression problem over heteroge...

Reduced dietary electrolyte balance affects growth performance and fecal odor compounds in growing pigs

Objective: Dietary electrolyte balance (dEB), which influences growth performance, has recently been suggested as a cost-effective acidification strategy for odor mitigation in swine production, yet its effects on fecal volatile fatty acids and volatile organic compounds remain p...

Uncertainty-aware active-learning design of high-strength, corrosion-resistant as-extruded Mg–Al–Zn–Mn–Ca–Y alloys using Bayesian neural networks

The present study proposes an uncertainty-aware design framework for as-extruded Mg–Al–Zn–Mn–Ca–Y alloys by integrating Bayesian neural network (BNN)-based property prediction, uncertainty-driven active learning (AL), and experimental validation. In the present AL cycle, tensile-...

Novel Thermostabilizing Formulation for Enhanced Stability of Foot-and-Mouth Disease Virus During Storage and Environmental Stress

Among the seven-foot-and-mouth disease virus (FMDV) serotypes, serotype O is relatively thermolabile, posing significant challenges for virus preservation and vaccine manufacturing. Therefore, this study aimed to develop an effective thermostabilizing formulation to enhance the t...

Joint Power Allocation and Power-Splitting Optimization for Underlay D2D Communications in SWIPT-Enabled DF Relay Networks

This paper investigates underlay device-to-device (D2D) communication in a simultaneous wireless information and power transfer (SWIPT)-enabled two-hop decode-and-forward cellular relay network. The D2D transmitter transmits both information and cancelable energy signals, with th...

Solitary Indeterminate Cell Histiocytosis Presenting as a Reddish Nodule on the Abdomen of a 4‐Year‐Old Boy: Clinicopathologic Correlation and Electron Microscopy Findings

ABSTRACT Indeterminate cell histiocytosis (ICH) is a clonal proliferative disorder of mononuclear phagocyte cells that shows features of both dendritic and histiocytic cells. Only around 100 cases of ICH were reported, and among them, only 24% of reported cases involve pediatric...

Benchmarking Core-Level X-ray Absorption with MRSF-TDDFT, RASPT2, and Stochastic GAS Using the XABOOM Set

Abstract Rapid advances in X-ray free-electron laser facilities are producing X-ray absorption spectra (XAS) with unprecedented detail, creating a pressing need for theoretical methods that are both accurate and computationally efficient to interpret subtle spectral features. In...

Anomaly Localization and Classification of Jaw Cysts and Tumours Using Anatomy-Conditioned Diffusion on Panoramic Radiographs

Objectives Accurate localization and classification of jaw cysts and tumours on panoramic radiographs are important for timely referral and treatment planning but remain challenging due to overlapping anatomy, heterogeneous lesion appearances, and dental restorations. This study...

Multi-Year Molecular Survey of Trypanosoma spp. in Wild Micromammals at 18 Surveillance Sites in the Republic of Korea: First Molecular Evidence of a Trypanosoma lewisi-like Genotype

Rodent-associated Trypanosoma spp. are widely distributed in wild rodents, but their epidemiology in the Republic of Korea remains incompletely characterized. This study investigated the prevalence, spatiotemporal distribution, and genetic characteristics of Trypanosoma spp. in 1...

Thermal-Time-Based Analysis of Garlic Growth and Yield Formation Under Contrasting Field Management

Garlic bulb yield formation depends on thermal-time availability, source–sink coordination, and field management, but their integrated effects under field-scale conditions remain unclear. This study evaluated garlic growth and final bulb weight (BW) during the 2024–2025 season ac...

A Solid-Phase Approach for the Synthesis of N 6-, N 7-, and C8-Substituted Adenine Derivatives

Abstract Adenine derivatives have been widely utilized as biologically active compounds owing to their diverse pharmacological properties. Although numerous synthetic approaches have been developed to access structurally diverse adenine analogues, their preparation is often hampe...
