Increased autoimmune disease burden before multiple sclerosis and neuromyelitis optica spectrum disorder diagnosis: A nationwide Korean cohort study

Background: A prodromal phase is increasingly recognized in multiple sclerosis and neuromyelitis optica spectrum disorder, but the temporal patterns of autoimmune diseases remain poorly characterized. Objectives: To evaluate the risk and timing of autoimmune diseases before multi...

Analytical model for load-deformation relationship of interior slab-column connections subjected to unbalanced moment

Damage in flat-plate floor systems subjected to lateral loading is known to concentrate at interior slab–column connections, yet practical nonlinear modeling approaches for performance-based seismic design remain limited. In the present study, an analytical model is presented for...

Income Dynamics and Incident Esophageal Cancer: A Retrospective Cohort Study

BACKGROUND: Although socioeconomic status is a recognized risk factor for esophageal cancer (EC), most studies have examined socioeconomic status at a single time point. We investigated the association between income dynamics and incident EC. METHODS: We analyzed 3,361,091 Korean...

Role-Dependent Mission-Energy Reserve Control for Federated Learning in Solar-Powered Maritime Edge Networks

Federated learning (FL) enables collaborative maritime perception without transferring raw observations, but solar-powered clients must preserve energy for platform-specific duties. Existing energy-aware FL generally applies a common battery constraint and cannot jointly protect...

Body Weight Change and Dementia Risk in Young and Middle‐Aged Adults With Type 2 Diabetes and Depression: A Nationwide Cohort Study

ABSTRACT Aim Type 2 diabetes mellitus (T2DM) and depression are established risk factors for dementia, yet clinically observable markers of neurocognitive vulnerability in younger adults with these comorbidities remain poorly characterized. We examined whether longitudinal body w...

Investigating the association between osteoarthritis and cardiovascular disease using a standardized cardiovascular health assessment tool in a nationwide health survey

Osteoarthritis (OA) and cardiovascular disease (CVD) are thought to be interrelated, but the nature of their connection remains unclear. We examined the association between OA and cardiovascular health (CVH) using Life’s Essential 8 (LE8), a standardized CVH assessment tool. We c...

Depression as a Risk of Lung Cancer in Women: a Nationwide Cohort Study

BACKGROUND: Lung cancer is a leading contributor to global cancer incidence and mortality. While depression has been linked to adverse health behaviors, particularly tobacco smoking, that may elevate cancer risk, the direct relationship between depression and lung cancer remains...

Graph Canonical Coherence Analysis

We propose graph canonical coherence analysis (gCChA), a novel framework that extends canonical correlation analysis to multivariate graph signals in the graph frequency domain. The proposed method addresses challenges posed by the inherent features of graphs: discreteness, finit...

Comparative evaluation of statistical learning methods for polygenic prediction in UK Biobank

Polygenic risk scores (PRS), which are calculated from genetic variants, provide a measure of an individual’s genetic predisposition to disease. They are widely used to predict disease risk, identify at-risk populations, and advance personalized medicine. However, PRS performance...

Cumulative Lifestyle Profiles and Osteoporotic Fracture Risk in Older Women: A Nationwide Korean Cohort Study

Background/Objectives: Modifiable lifestyle behaviors may be relevant to osteoporotic fracture risk, but their cumulative association across different levels of skeletal health remains unclear. This study investigated the association between a cumulative lifestyle score and osteo...

A K-/Ka-Band Fully Integrated Stacked CMOS Power Amplifier with Capacitive Neutralization for 5G Millimeter-Wave Applications

This paper presents a fully integrated three-stage stacked power amplifier (PA) operating in the K-/Ka-band, fabricated using a TSMC 65 nm CMOS process for fifth-generation (5G) millimeter-wave applications. To improve the output power without sacrificing reliability, a two-stack...

Party membership motivations and political activism in a polarized new democracy: Evidence from South Korea

This study investigates party membership motivations in South Korea, a highly polarized new democracy, and how they distinctively shape intra-party and campaign participation. Using survey data from 1,410 Democratic and People Power Party members, we evaluate the General Incentiv...

Emerging Therapeutic Strategies in Small-Cell Lung Cancer: From Adaptive Resistance to Precision Therapy

Background/Objectives: Small-cell lung cancer (SCLC) remains one of the most therapeutically challenging malignancies despite recent advances in chemoimmunotherapy. Although platinum–etoposide combined with programmed death ligand 1 (PD-L1) blockade has modestly improved survival...
