Food-Related Online Media Viewing (Mukbang and Cookbang) and Sugar-Sweetened Beverage and Artificially Sweetened Beverage Consumption Among Korean Adolescents: Using the 2025 Korea Youth Risk Behavior Survey

Background/Objectives: Adolescents are increasingly exposed to food-related online media, with mukbang and cookbang representing prominent forms of such media. Mukbang refers to an online genre in which hosts consume food while interacting with viewers, whereas cookbang refers to...

Transform-to-thrust reactivation of a fossil back-arc spreading system: Evidence from marine magnetic anomalies in the East Sea (Japan Sea)

Transform faults contain rheological weaknesses that can be reactivated into either divergent or convergent boundaries, depending on tectonic stress regime. While rifting triggered from transform fault is well documented, geophysical evidence demonstrating compressional reactivat...

Residual-gated generative additive joint-bias identification and uncertainty-weighted fault compensation for quadruped robots with scarce data

Repeated actuator-fault injection on a physical quadruped is costly and can damage motors or gearboxes, which makes continuous fault-value identification difficult when only scarce sequences are available. This study targets command-equivalent additive joint bias. A temporal gene...

Apparent versus Cross-Validated Selectivity in Seawater Electrolysis: Linking Product Analysis to Catalyst–Electrolyte Interface Dynamics

Selectivity in seawater electrolysis is commonly evaluated by comparing the oxygen evolution reaction (OER) and chlorine evolution reaction (CER). However, the products measured after electrolysis do not always directly represent those initially formed at the catalyst-electrolyte...

A pair of chitosan receptors confer broad-spectrum fungal resistance

Chitosan, a major fungal cell wall component, activates plant immunity, yet the underlying perception mechanism remains unknown. In this study, we identified OsFID1, an apoplast-localized DUF26 domain protein, as a chitosan-binding receptor essential for chitosan-triggered immuni...

Effect of Local Intermediate Coating Thickness on Metastructure-Induced Guided-Wave Redistribution: A Two-Dimensional Finite-Element Study

Protective coatings change the cross-section through which guided waves travel, and metastructures redistribute those fields. When a metastructure is bonded through a coating rather than directly to its host, the coating enters the integration path. This two-dimensional finite-el...

Breathing chimera states from purely triadic interactions

Chimera states, characterized by the coexistence of synchronized and desynchronized dynamics in identical oscillators, are typically studied in systems with pairwise interactions. Recent studies have shown that purely higher-order interactions can support chimera states. Here, we...

Zingiberis Rhizoma Ethanol Extract Attenuates Recognition Memory Deficits and Neuroinflammation in a Mouse Model of Bilateral Common Carotid Artery Stenosis

Chronic cerebral hypoperfusion (CCH), a key contributor to vascular dementia (VaD), causes white matter injury and neuroinflammation. We evaluated the neuroprotective effects of 6-gingerol-rich Zingiberis Rhizoma ethanol extract (ZRex) in a mouse bilateral common carotid artery s...

Interactive effects of wheat cultivar and ultracentrifugal milling on purple whole‐wheat flour functionality, phytochemical properties, and noodle quality

Abstract BACKGROUND Purple whole‐wheat flour (WWF) contains anthocyanins and phenolics, but bran‐rich components and genotype‐dependent kernel and starch traits can impair noodle processing and texture. This study evaluated the effects of ultracentrifugal milling on flour functio...

Image-Based Quantitative Pore Analysis of Cementitious Materials: A Scale-Resolved Review of X-Ray CT Methods and Metrics

X-ray computed tomography (CT) has become the reference non-destructive technique for the three-dimensional characterization of the pore structures of cementitious materials. This review maps 140 application studies—spanning cement paste, mortar and concrete, from air-entrained,...

A Multi‐Objective Optimization and Decision‐Making Framework for Safety‐Critical Ground Vehicle Endurance Tests

ABSTRACT Accelerated endurance testing for safety‐critical ground vehicles requires reproducing field‐induced fatigue within limited time while maintaining stable and reliable evaluation conditions. However, conventional procedures rely on empirical rules or component‐level metri...

Bulky‐Group‐Functionalized Bidentate Pt(II) Complexes With Aggregation‐Induced Emission for Blue Phosphorescent Organic Light‐Emitting Diodes

Pt(II) metal complexes with aggregation‐induced emission (AIE) properties are creating new opportunities in the fields of optoelectronics and their applications. We synthesized a series of AIE‐active sky blue and bluish green Pt(II) complexes with varying structures, such as (Pt1...

Does forest management reduce wildfire severity? Evidence from 1050 plots in a South Korean Megafire

Increases in large wildfires are commonly attributed to climate change, an attribution well supported in summer-dry regions such as western North America. In the East Asian monsoon region, however, national fire trends have diverged under broadly similar warming: forest fire acti...

Unintended consequences of vaginal misoprostol use in a patient with hydatidiform mole

Rationale: Hydatidiform mole (HM) is usually managed by suction curettage, while misoprostol is not recommended as a method of medical evacuation for molar pregnancy because of concerns regarding incomplete evacuation and postmolar gestational trophoblastic neoplasia. The use of...

Association of Estimated Arterial Stiffness with Collateral Status and Functional Outcome after Endovascular Thrombectomy: A Secondary Analysis of the OPTIMAL-BP Trial

PURPOSE: Estimated pulse wave velocity (ePWV) is a surrogate of arterial stiffness that may influence stroke outcomes and potentially affect collateral circulation. We examined the association of ePWV with collateral status and 3-month functional outcome after successful endovasc...

The relationship between political YouTube news use and affective polarization in election vs. non-election contexts: mediation by hostile expression and moderation by political rumor acceptance

User-generated political YouTube channels often disseminate conspiracy narratives and partisan information, potentially reinforcing echo-chambers and intensifying hostility toward political outgroups. Against this backdrop, this study examines the interplay among political YouTub...

Cost-competitive design of sustainable urea production: Synergizing solid oxide electrolysis and oxy-fuel combustion-based carbon capture

Urea is a vital nitrogen fertilizer for global food security; however, its production remains carbon-intensive owing to heavy reliance on fossil fuel–based H 2 . To reduce the carbon emissions of the urea production process, capturing CO 2 from the flue gas has emerged as a promi...

Association of PTH1R Gene Polymorphisms with Three-Dimensional Mandibular Morphology Across Three Recruitment Cohorts

Parathyroid hormone 1 receptor (PTH1R) regulates chondrocyte differentiation and mandibular condylar cartilage development, but its contribution to adult mandibular morphology remains unclear. We investigated associations of two PTH1R single-nucleotide polymorphisms (SNPs), rs724...

Wind-Load Analysis of a Floating Structure with Different Levels of Geometric Resolution Using OpenFOAM

Wind loads acting on an offshore floating structure are important for the global performance analysis and mooring design. In early design stages, detailed topside geometry may not be fully available; therefore, a wind-load analysis should be performed using simplified geometries....

Activation of the MprBA two-component system in Mycobacterium smegmatis under acidic and respiration-inhibitory conditions and crosstalk between MprA and KdpD

ABSTRACT The MprBA two-component system (TCS) plays a critical role in Mycobacterium tuberculosis persistence and forms a signaling pathway with the alternative sigma factors SigE and SigB. Here, we demonstrate that the MprBA-SigE–SigB signaling pathway is activated in Mycobacter...
