Impact of Observation Density of Next-Generation GeoHIS on Global Numerical Model Performance: A KIM-OSSE Study

The geostationary hyperspectral infrared sounder (GeoHIS) provides atmospheric variables at high spatiotemporal resolution. Consequently, GeoHIS can provide valuable information for improving real-time forecasting and enhancing the performance of numerical weather prediction (NWP...

Synergetic Enhancement in Thermoelectric Performance via Localized Magnetic Moments and Lattice Softening

ABSTRACT Magnetism‐assisted transport is achieved in Mn‐containing SnSe magnetic nanocomposites, where superparamagnetic MnSe nanoprecipitates are introduced to modulate both carrier and phonon scattering. Transmission electron microscopy reveals well‐dispersed 5–10 nm MnSe inclu...

Data-driven personalization of just-in-time adaptive mental health intervention via two-stage reinforcement learning approach

Most digital mental health interventions still deliver uniform content, without accounting for how a user’s fluctuating psychological state interacts with their stable individual characteristics. We propose a two-stage offline reinforcement learning (RL) framework, trained on dat...

Reflex Charging for Anion‐Derived Solid Electrolyte Interphase Formation

ABSTRACT Lithium (Li) metal offers exceptional energy density but suffers from unstable interphases that lead to dendrite growth and poor reversibility. Because the interphase is established during the earliest stages of operation, controlling its formation is critical for stabil...

Prenatal PM2.5 exposure drives epigenetic reprogramming of fetal macrophages linked to atopic dermatitis

Abstract Prenatal environmental exposures are increasingly recognized as contributors to atopic dermatitis (AD), yet the underlying mechanisms remain unclear. Fine particulate matter (PM 2.5 ), a complex mixture of airborne pollutants, has been associated with elevated risk of al...

Reflex Charging for Anion‐Derived Solid Electrolyte Interphase Formation

ABSTRACT Lithium (Li) metal offers exceptional energy density but suffers from unstable interphases that lead to dendrite growth and poor reversibility. Because the interphase is established during the earliest stages of operation, controlling its formation is critical for stabil...

Dynamic load transfer behaviour of piled raft foundations in saturated sand

This study investigates the dynamic response and load-sharing mechanism of a piled raft foundation subjected to earthquake loading. A series of 1g shaking table tests was conducted to analyse the dynamic behaviour of soil–structure interaction. The experimental setup involved mod...

Interpretable machine learning models for classifying lateral epicondylitis based on wrist range of motion and strength in assembly line workers

Background Lateral epicondylitis (LE) is a prevalent overuse injury among workers performing repetitive wrist movements. Altered wrist range of motion (ROM) and reduced muscle strength occur in individuals with LE; however, their combined utility for classifying LE remains unclea...

Regional CO 2 and CH 4 inversion system using WRF-Chem (v4.4)/DART (v9.8.0) and continuous high-precision observations over the Korean Peninsula

Abstract. Quantifying greenhouse gas (GHG) emissions over complex terrain remains a significant challenge for conventional inversion systems due to the high sensitivity of tracer transport to surface heterogeneity. We develop a high-resolution dual-species GHG top-down inversion...

Instability control and emission characteristics of methane/hydrogen non-premixed flames under DC electric fields

This study experimentally investigated the Kelvin–Helmholtz instability in methane/hydrogen non-premixed flames induced by velocity differences between the fuel jet and co-flow. Using a co-flow burner, various fuel and co-flow velocity conditions were tested to identify the regim...

MODEL-informed nivolumab less frequent dosing using virtual patients with solid tumors

Less frequent nivolumab dosing has been assessed for more efficient dosing, but there is no conclusive evidence. In this research, we suggested an appropriate model-informed drug dosing using virtual patients collected from the results of multiple clinical studies to provide a ra...

Chirality-Matched Cyclopropenimine–Thiourea Organocatalysis for Regiocontrolled Ring-Opening Polymerization of Methyl Glycolide

Abstract Poly(lactic-co-glycolic acid) (PLGA) is widely used in biomedical applications owing to its high biodegradability and biocompatibility. Although the ring-opening polymerization (ROP) of methyl glycolide (MeG) offers a route to synthesizing alternating PLGA, the comparabl...

Initial High-Frequency Amplification Accuracy Predicts Long-Term Hearing Aid Fitting Outcomes: A Real Ear Measurement-Based Study

Background: To investigate whether the accuracy of initial hearing aid amplification verified by real ear measurement (REM) predicts long-term fitting outcomes after one year, and to identify frequency-specific predictors associated with sustained fitting precision. Methods: This...

Integrative Genomic Analysis Reveals Molecular and Clinical Disparities between Bladder and Upper Tract Urothelial Carcinoma in K-MASTER Program

Purpose: The clinical outcome of urothelial carcinoma presents significant variability, reflecting its molecular composition, epidemiologic attributes, and primary site of origin. Despite histological similarities, upper tract urothelial carcinoma (UTUC) and bladder urothelial ca...

The Traumatic Event Checklist for North Korean Defectors

Objective This study aimed to develop and validate a trauma checklist specifically designed to capture the complex and culturally unique potentially traumatic events (PTEs) experienced by North Korean defectors (NKDs), in alignment with International Classification of Diseases, 1...

Development of an artificial intelligence model for predicting cardiovascular disease in MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with cardiovascular disease (CVD). Conventional CVD risk scores often fail to reflect MASLD-specific factors. We aimed to develop and validate an artificial intelligence (AI) model for 10-year CVD risk...

Population Pharmacokinetic Comparability of CT-P16 Versus EU-Avastin® and US-Avastin® in Healthy Subjects and Patients with Non-Squamous Non-Small Cell Lung Cancer

CT-P16 (Vegzelma ® ) is a bevacizumab biosimilar approved for indications including non-squamous non-small cell lung cancer. We developed an integrated population pharmacokinetic model pooling data from two phase I studies in healthy subjects and one phase III study in patients w...

Factors associated with the health-related quality of life of adolescents with atopic dermatitis in South Korea: a cross-sectional study

PURPOSE: Atopic dermatitis (AD) in adolescents has received less attention than AD in infants and children. However, AD can persist or worsen after school age and affect health-related quality of life (HRQoL) beyond adolescence. This study aimed to examine HRQoL and its associate...
