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...

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...

High Coverage Does Not Guarantee Regression Detection: A Target-Blind Audit of Representative Task Panels for Versioned AI Coding Agents

Re-evaluating versioned artificial intelligence (AI) coding agents is expensive, motivating small task panels that represent a full benchmark. We audit whether such representativeness predicts regression-screening value (a regression is a task the previous configuration solved an...

Effect of Auricular Acupoint Stimulation on Weight in Adults with Overweight or Obesity: A Systematic Review and Meta-Analysis

Objectives: To systematically evaluate the effectiveness of auricular acupoint stimulation for weight reduction and metabolic outcomes in adults with overweight or obesity. Design: Systematic review and meta-analysis of randomized controlled trials. Methods: Six electronic databa...

Molecular Mechanism of AtCAX3-Induced BPA Tolerance in Plants

Cation/H+ Exchangers (CAXs) are involved in the sequestration of cations such as Ca2+, Mn2+, Li+, Zn2+, and Cd2+ from the cytosol into the vacuole using proton gradients. Our previous studies demonstrated the involvement of AtCAX3 in Cd2+ tolerance. In this study, we investigated...

A multi-scale analysis of spatiotemporal variability and environmental influences on urban noise

Urban noise has emerged as a critical environmental stressor affecting public health in densely populated cities. Most existing studies, however, rely on temporally aggregated approaches that obscure how noise-environment relationships vary across seasons and times of day, limiti...

Long- and short-run determinants of metro ridership in Seoul: A vector error correction model approach

The metro system is essential infrastructure underpinning urban sustainability and citizen mobility. The Seoul metro system has experienced continuous infrastructure expansion, multiple policy changes, and major external shocks over the past 25 years. This study examined the shor...

Old-age poverty, basic pension policy periods, and late-life suicide in South Korea: a descriptive ecological analysis, 2012–2024

South Korea has exceptionally high old-age poverty and late-life suicide rates. Both declined during a period spanning the 2014 introduction of the Basic Pension and subsequent benefit changes. We described their national trajectories from 2012 to 2024 and compared late-life suic...

Diagnosing public transport disadvantage in multi-activity accessibility: Opportunity-side and service-side signals

Multi-activity daily travel requires access to several everyday opportunities within limited time budgets. Public transport (PT), however, often provides less effective door-to-door access to such opportunity combinations than private cars. Using scheduled PT and private-car trav...

Quantifying informational illiquidity in corporate bond markets

We develop a structural credit-risk model to quantify the impact of information asymmetry on corporate bond pricing. In the model, bondholders (i) sell their bonds either to meet liquidity needs or to exploit informational advantages and (ii) have the option to credibly reveal th...

Deployment-Oriented Evaluation of Lightweight IMU-Based Human Activity Recognition: On-Device Efficiency and Streaming Feasibility

On-device Human Activity Recognition (HAR) requires balancing accuracy and deployment efficiency on constrained hardware. We present Lightweight Human Activity Recognition (L-HAR), a controlled comparison of Baseline and Lightweight Temporal Convolutional Network (TCN), Transform...

Nanocube-size-dependent Fermi level positioning in Cu2O/TiO2 S-scheme heterojunctions for optimized VOC photodegradation

Precise tuning of the Cu 2 O Fermi-level position is achieved by tailoring its crystal size (30, 55, and 315 nm). The Fermi-level position of Cu 2 O and the resulting interfacial electronic structure of Cu 2 O/TiO 2 S-scheme heterojunctions (CT-x: x= edge length in nm) have been...
