Local Acidity as a Corrosiveness Descriptor of Fluorinated Ether Solvents in Lithium–Metal Batteries

ABSTRACT Electrolyte engineering based on solvent fluorination has proven effective for stabilizing lithium (Li) metal batteries by weakening the Li + ‐solvent interaction. However, the influence of fluorination on the chemical reactivity of an electrolyte toward Li metal remains...

De-familialization of care and the emerging crisis of unmet needs among older adults in South Korea

Unmet long-term care (LTC) needs are a critical policy indicator for aging societies. Using repeated cross sectional data from the nationally representative National Survey of Older Koreans (2014 and 2023), we examined changes in unmet LTC needs among community-dwelling older adu...

Fast All‐Sky Hyperspectral Infrared Radiative Transfer With Physically Recursive Cloud Treatment

Abstract Clouds strongly modify thermal infrared radiances through absorption, emission, and multiple scattering, yet rigorous line‐by‐line (LBL) gas absorption coupled with multi‐stream scattering remains too expensive for large ensembles of all‐sky hyperspectral simulations. We...

Malignant melanoma in an African penguin (Spheniscus demersus): a case report

This report describes malignant melanoma in a 21-year-old African penguin (Spheniscus demersus) maintained under captive management. The penguin exhibited a rapid decline in clinical condition, characterized by lethargy and anorexia, and despite 5 days of supportive fluid therapy...

Ultra-processed food intake, genetic polymorphisms, and the risk of obesity in a pooled analysis of three prospective cohorts

Obesity is a major risk factor for non-communicable diseases and mortality. This study aimed to examine the associations between ultra-processed food intake and the risks of obesity and weight gain, and to evaluate whether these associations differed by polygenic scores for obesi...

Structural barriers to knowledge co-production in the context of public health crisis

Abstract Knowledge translation (KT) is widely recognized as essential for evidence-informed policymaking, yet the research-policy gap persists. Co-production, namely collaborative knowledge production among researchers, policymakers, and practitioners, has emerged as a promising...

Engineered nanocomplex for targeted delivery of Beclin1 peptide enables autophagy-mediated tumor suppression and immune activation

Although autophagy is a central regulator of cellular homeostasis, its potential to reprogram the immunosuppressive tumor microenvironment (TME) remains largely unexplored. Within the TME, the dysregulated deposition of Tenascin-C (TNC) establishes a formidable extracellular matr...

Patterns of failure after primary treatment and prognostic factors in stage I, grade 2-3 endometrial cancer

Purpose: This study aimed to characterize recurrence patterns and identify prognostic factors in patients with stage I, grade 2-3 endometrioid endometrial cancer. Materials and Methods: We retrospectively analyzed 298 patients with 2009 International Federation of Gynecology and...

Assessment of urban green space in Suwon special city: focusing on everyday nature spaces in neighborhood level

Abstract Urban green spaces are essential resources directly linked to citizens’ quality of life, providing a wide range of ecosystem services. However, existing policies and research have primarily focused on quantitative indicators such as area, while overlooking the qualitativ...

Weak Cross-Assemblage Concordance of Survey-Round Community Dissimilarity in Korean Lotic Waters: A Matched National Biomonitoring Analysis

National biomonitoring programs increasingly survey multiple biological assemblages, but whether one biological element can serve as a surrogate for the magnitude or ranking of repeated-survey compositional displacement remains unresolved under strict site-year-round matching. We...

Variation in meningioma recurrence risk estimates across observational cohorts: the influence of calendar time, WHO classifications, geographical settings, and healthcare systems

Abstract Purpose Recurrence risk estimates underpin meningioma research, including molecular classification and clinical trial benchmarking, yet are often based on retrospective or historical data. The aim of this study was to assess the variation of recurrence risk estimates acr...

Random-noise denoising for turnaround-fibre DAS-VSP data via the Noise2Noise framework

Summary In this study, we develop a deep learning-based approach for denoising raw distributed acoustic sensing (DAS)-vertical seismic profiling (VSP) data. The data were acquired using vibroseis sources at borehole sites in Dangu-ri and Janghang-ri, Gyeongju, Republic of Korea....

Domain-Specific Cognitive Concordance in Older Married Couples

Importance Spousal similarity in late-life cognition has been reported, but whether concordance differs across cognitive domains remains unclear. Objective To examine whether cognitive concordance among older married couples is domain specific by comparing real couples with demog...

ODIN: Confirmation and 3D Reconstruction of Six Massive Protoclusters at Cosmic Noon

Abstract Protoclusters represent sites of accelerated galaxy formation and extreme astrophysical activity characteristic of dense environments. Identifying massive protoclusters and mapping their spatial structures are therefore crucial for understanding how large-scale environme...

Longitudinal Analysis of Mandibular Condylar Growth Trajectories in Growing Patients

This study aimed to analyze the continuous morphological changes of the mandibular condyle during growth using longitudinal panoramic radiographic data and visualize these changes as growth trajectories. A total of 100 growing patients with 564 panoramic radiographs obtained betw...

Clinical, Enamel, and Radiographic Features of Amelogenesis Imperfecta in Pediatric Patients: A Multicenter Study

This study aimed to characterize the clinical, enamel, and radiographic features of amelogenesis imperfecta (AI) in pediatric patients in Korea and to compare these features across AI phenotypes. This multicenter retrospective study reviewed records of 39 patients aged < 18 years...

Impact of Concomitant Grade I Degenerative Spondylolisthesis on Clinical and Radiographic Outcomes Following Biportal Endoscopic versus Microscopic Laminectomy for Lumbar Spinal Stenosis: A Post Hoc Analysis of a Multicenter Randomized Clinical Trial

Study DesignPost hoc analysis.ObjectiveTo determine whether Meyerding grade I degenerative spondylolisthesis (DS1) modifies 12-month clinical or radiographic outcomes after biportal endoscopic laminectomy (BE-L) versus microscopic laminectomy (M-L) for lumbar spinal stenosis, and...

Building digital business ecosystem resilience through orchestration capability: The sequential roles of ecosystem knowledge integration and ecosystem service innovation

This study examines how digital business ecosystem orchestration capability enhances ecosystem resilience through sequential mediation by ecosystem knowledge integration and ecosystem service innovation, while accounting for the moderating effect of ecosystem dynamism. Data were...

Minimal rank of primitively n-universal integral quadratic forms over local rings

Abstract Let F be a local field and let R be its ring of integers. For a positive integer n , an integral quadratic form defined over R is called primitively n -universal if it primitively represents all quadratic forms of rank n . It was proved in [7] that the minimal rank of pr...

Civil Servants' Compliance with Conflict‐of‐Interest Regulation: Evidence from a List Experiment

ABSTRACT While regulatory governance scholarship has paid significant attention to the normative importance of ethics reform in government, empirical evidence on compliance remains scant. Drawing on insights from the social value activation model and behavioral ethics, this study...
