Learning Popularity-Aware User Representations for Sequential Recommendation via Retrieval-Augmentation

Sequential recommendation methods are important in recommender systems, as they capture users’ dynamic interests from their historical behavior sequences. However, most existing methods have two limitations. First, they heavily rely on semantics from only a target user's interact...

Integrative clinical–genomic modeling evaluates exploratory Non-APOE candidate signals in Alzheimer’s disease

Alzheimer’s disease (AD) is characterized by a genetic architecture dominated by APOE , while predictive modeling in clinically enriched cohorts is often driven by neuropsychological and clinical variables. This combination limits the interpretability of secondary genetic signals...

All‐Sputtered Oxide n‐p Heterojunction Anti‐Ambipolar Transistors for Semantic Segmentation Networks

ABSTRACT Neuromorphic vision provides an efficient route for extracting meaningful information from visual inputs and supporting intelligent perception in dynamic environments. However, visual scenes acquired under excessive or insufficient illumination often contain distorted co...

Fairness begins at recruitment: a multilevel analysis of procedural selection fairness, union participation, reward fairness, and job satisfaction

Purpose Grounded in Applicant Attribution-Reaction Theory (AART), this research investigates the psychological mechanisms by which procedural fairness during hiring influences post-entry employee attitudes. By extending AART to the context of upward mobility, this study offers a...

Non-typhoon extreme waves in the Northeast Asian Marginal Seas: Observation-based identification, synoptic conditions, and classification

This study presents an observation-based approach for identifying, characterizing, and classifying non-typhoon extreme waves in the Northeast Asian Marginal Seas using in-situ wave and wind measurements, with reanalysis data used to interpret the associated synoptic conditions. E...

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...

Charge‐Domain In‐Memory Computing With NAND‐Compatible Ferroelectric Memcapacitor Crossbar

ABSTRACT Rapid growth in artificial intelligence has intensified the need for energy‐efficient computing architectures beyond the conventional von Neumann paradigm. While memristive in‐memory computing has attracted significant attention, its low cell resistance causes static pow...

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...

Comparative metabolomic characterization of secondary metabolites in Gnaphalium affine D. Don considering the influence of growth stages and cultivation systems

Gnaphalium affine has long been consumed as a food and medicinal plant due to its nutritional and bioactive properties. This study comprehensively examined variation in metabolites and antioxidant activities across growth stages and between two cultivation environments of G. affi...

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,...

Simulation-guided SiOx–graphite anode design for mitigating reaction heterogeneity and enhancing fast-charging performance in lithium-ion batteries

SiO x –graphite composite anodes offer high energy density and improved rate capability owing to the high theoretical capacity of SiO x (∼1400 mAh g −1 ); however, their cycle life under fast-charging conditions remains severely limited. This study presents a simulation-guided de...

Hydration channel engineering in Tröger’s base-POP membranes for mono/multivalent cation and anion discrimination

Sustainable recovery of critical resources from complex aqueous streams is constrained by membranes that fail to combine rapid ion transport with precise mono/multivalent discrimination. Here, we report Tröger’s base-derived porous organic polymer (POP) membranes with rigid, cova...

Thermal optimization of an air-cooling system of 2 kAh battery module for energy storage systems

Effective thermal management is crucial for ensuring the safety and longevity of lithium-ion battery energy storage systems (ESSs) by preventing localized heat accumulation and thermal runaway. In this study, an optimized air-cooling strategy was investigated for a 2 kAh commerci...

Multi-tracer evaluation of cesium-137 bioaccumulation and trophic transfer in marine organisms off Jeju Island, Korea

Radionuclides accidentally released from nuclear facilities into the marine environment may affect ecosystems far from their original sources, yet their ecological behavior in such regions remains poorly understood. Using a multi-tracer approach, we evaluated 137 Cs bioaccumulati...

Estimated small dense low-density lipoprotein cholesterol and incident myocardial infarction in patients undergoing dialysis: a nationwide cohort study

Background Small dense low-density lipoprotein cholesterol (sdLDL-C) is an atherogenic LDL subfraction that may reflect lipid-related coronary risk beyond conventional cholesterol levels. Estimated sdLDL-C (E-sdLDL-C) is calculated from a standard lipid panel, but its prognostic...

Clarifying the Concept of “Unanticipated Transfer to the ICU”: A Scoping Review

Unanticipated transfer to the intensive care unit (ICU), typically defined as an unscheduled escalation of care from inpatient general wards, is widely used in clinical research as a marker of adverse events, clinical deterioration, and system failure. However, its conceptual mea...

Exploring the potential of AI-driven brain–computer interfaces for Alzheimer’s disease: an integrated framework for diagnosis and therapeutic intervention

Early diagnosis and timely intervention are critical in Alzheimer's disease (AD), yet conventional assessments fail to capture longitudinal neural dynamics. Although traditional biomarker frameworks offer essential pathological insights, they remain constrained by high costs and...
