Pressure-Robust Staggered DG Methods for the Navier–Stokes Equations on General Meshes

Abstract In this paper, we design and analyze staggered discontinuous Galerkin methods of arbitrary polynomial orders for the stationary Navier–Stokes equations on polygonal meshes. The exact divergence-free condition for the velocity is satisfied thanks to the carefully designed...

Three-Year Outcomes of Drug-Eluting Stents, Drug-Coated Balloons, and Non-Drug-Eluting Devices in Native Femoropopliteal Artery Disease: An Analysis of the K-VIS ELLA Registry

Background: Although drug-eluting devices have demonstrated improved efficacy in femoropopliteal artery (FPA) disease, evidence on their long-term clinical outcomes in realworld practice remains limited.Methods: Using data from the multicenter Korean Vascular Intervention Society...

Chronic ER stress couples cellular senescence with pigment retention

Solar lentigines are characterized by persistent basal hyperpigmentation. We hypothesized that chronic IRE1α-mediated ER stress simultaneously increases melanocyte melanogenesis and impairs keratinocyte melanophagic clearance, generating a pigment-retention state. We analyzed pai...

Embedded CTAB enables depolymerization of PLA composite films under mild, household-compatible alkaline conditions

Polylactic acid (PLA) is considered a promising biodegradable material; however, its complete degradation is typically limited to industrial composting systems, making household-level end-of-life management challenging. In this study, we developed a simple and efficient PLA depol...

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

ABSTRACT Oxidative degradation of Ti 3 C 2 T x MXene in aqueous and biological environments remains a persistent obstacle to its long‐term use in biomedical applications, yet the role of the surrounding polymer matrix in governing this process has received little systematic atten...

Age- and sex-adjusted genomic differences between Korean and Beat AML cohorts

Genomic profiling plays a central role in risk stratification and therapeutic decision-making in acute myeloid leukemia (AML), yet the clinical implications of population-specific genomic architectures remain incompletely defined. We conducted a prospective, multicenter study of...

Tinnitus Practice Patterns in Korean University Hospitals: Findings from a 2025 Nationwide Survey and Comparison with 2013

Objectives.: A 2013 nationwide survey described tinnitus management in Korean university hospitals. Since then, conceptual frameworks have broadened, and new therapies have emerged. We aimed to investigate tinnitus practice patterns among Korean university hospital otologists in...

Robotic Palpation for Spatiotemporal Arterial Pulse Quantification and Mapping Using Multilevel Microdome‐Based Soft Pressure Sensors

ABSTRACT Humanoid robots have advanced capabilities through physical and physiological examinations, but their reliance on visual information limits biological‐object assessment, underscoring the need for tactile perception. Current tactile systems primarily detect basic contact...

Deterministic Switching‐Path Engineering of CMOS‐Integrated 2D Memristors for Neuromorphic Computing

ABSTRACT Two‐dimensional (2D) memristors are promising for low‐power and high‐speed neuromorphic hardware. However, their performance under circuit‐level constraints remains limited because resistive switching relies on native defects, hindering precise control of filament format...

Breaking of π‐Continuity by σ‐Linkers in Covalent Organic Frameworks for Efficient Photoreduction and Recovery of Gold From Electronic Waste

Photoreduction of metal ions plays a central role in the recovery of precious metals from electronic waste, yet its design is still largely governed by a semiconductor paradigm that links extended π-conjugation and long-range charge transport to superior performance. Herein, we c...

Transition of children with chronic gastrointestinal and liver disease to adult care: A multicentre Asian survey of paediatric gastroenterologists

OBJECTIVES: The rising incidence of chronic gastrointestinal conditions and better survival of children with life-limiting diseases have resulted in the need for continuity of care into adulthood. This study aimed to detail transition practices in paediatric gastroenterology and...

Repurposing irosustat for malaria: host-targeted antiplasmodial activity via cholesterol sulfate modulation against drug-resistant Plasmodium falciparum

Abstract Background The urgent global need for novel antimalarial drugs targeting Plasmodium falciparum has intensified due to rising mortality and drug resistance. This study examines a host-directed strategy targeting lipid metabolism by evaluating the antiplasmodial activity o...

Pre-Compressed Conductive Sponge Pressure Sensor with Reduced Hysteresis for Sustained Interface Pressure Monitoring

Abstract Skin-interface pressure monitoring is essential for preventing pressure injuries caused by sustained mechanical loading between the human body and support surfaces. However, porous structure-based pressure sensors often exhibit high mechanical hysteresis and unstable res...

Rapid progression of coronary atherosclerosis across glycemic status: a serial coronary computed tomography angiography study from the PARADIGM registry

Rapid progression of coronary atherosclerosis is associated with an increased risk of future adverse cardiovascular events. However, evidence regarding the association between glycemic status and rapid plaque progression (RPP) in the major epicardial coronary arteries remains lim...

Surface Reconstruction-Driven Insulating Behavior in Metallic Charge-Density-Wave 1T-TaSe2

Abstract Bulk 1T-TaSe2 is metallic, yet its surface consistently exhibits an insulating gap─a dichotomy long attributed to a surface Mott insulator driven by enhanced electron correlations. Using density functional theory calculations, we show that this insulating surface instead...

Utilisation and barriers to health check-ups among people living with human immunodeficiency virus in South Korea: a cross-sectional survey of clinic-attending patients

People living with human immunodeficiency virus (PLWH) continue to experience higher mortality rates than that in the general population. As this increased mortality is largely attributed to chronic comorbidities, regular health check-ups are required. This cross-sectional survey...

RGB-Sensitive TeOx/InZnO Heterojunction Phototransistor for Visible-Light-Driven Optoelectronic Synapses

Abstract Visible-light-responsive optoelectronic synapses are attracting increasing attention for neuromorphic vision systems because they integrate optical sensing and information processing within a single device. However, conventional oxide semiconductor phototransistors are g...
