Interfacial engineering of sulfur-modified g-C3N5/V2O5 heterostructures for enhanced overall water splitting and sonophotocatalytic tetracycline degradation

Electrochemical water splitting (EWS) and photocatalytic advanced oxidation processes (AOPs) are promising approaches for clean hydrogen production and environmental remediation; however, their efficiency is often limited by high overpotentials, rapid charge recombination, and po...

Orientation-dependent ballistic response of textured Mg alloy plates: From deformation mechanisms to macroscopic fracture

α -Mg alloys inherently exhibit pronounced plastic anisotropy owing to the limited slip systems of their hexagonal close-packed lattice; this anisotropy is amplified by the crystallographic texture developed during thermomechanical processing. Despite extensive studies on quasi-s...

Seroprevalence of Toxoplasma gondii among animal-associated workers and companion animals in South Korea

Abstract Toxoplasma gondii is a widely distributed zoonotic parasite at the human–animal interface. However, studies simultaneously evaluating animal-associated workers and companion animals remain limited in South Korea. This multi-regional cross-sectional study aimed to estimat...

CPD nth Roots of Subnormal Operators are Subnormal

We investigate the nth-root problem for bounded operators on a Hilbert space within the class of conditionally positive definite (CPD) operators determined by the Lévy–Khintchine formula. This class contains subnormal operators, complete hypercontractions of order 2, and 3-isomet...

Spatial mixed models for assessing environmental exposure effects on the microbiome

Environmental exposures such as air pollution may influence human health partly through microbiome, but statistical modeling is challenged by spatial dependence across regions and ecological correlations among taxa. We propose SpaMixed, a novel spatial mixed modeling framework fo...

Small Rotation Blocks and the Order-Six Stable Marriage Problem

We prove that a finite poset with at most fifteen elements, width at most three, and the following common-incomparability property has at most 48 antichains: for every x < y, the elements incomparable with both x and y form a chain of size at most two. An explicit fifteen-element...

From stem cell therapy to precision regenerative cardiology: integrating the gut microbiota and multi-omics in myocardial infarction

Myocardial infarction (MI) remains a major cause of heart failure because extensive cardiomyocyte loss exceeds the limited regenerative capacity of the adult heart. Adult progenitor cell- and mesenchymal stem cell-based therapies promote cardiac repair predominantly through parac...

HERMES: Experience replay and operator plasticity in evolutionary UAV path planning

Evolutionary algorithms are effective for UAV path planning in complex environments, yet they typically operate as amnesic search processes. Even when coupled with local heuristic repair, they repeatedly reconstruct similar obstacle-avoidance maneuvers without retaining reusable...

Fabrication and Characterization of Hydrogels From NaOH ‐Dissolved Lignocellulose and Carboxymethyl Cellulose

ABSTRACT Carboxymethyl cellulose (CMC) has been developed as a renewable material for highly absorbent hydrogels, but excessive swelling and insufficient network stability have limited its practical applications. Here, organosolv bamboo pulp containing approximately 20 wt% residu...

Prognostic implications of the duration of continuous kidney replacement therapy in 3-month survivors of acute kidney injury: findings from the LINKA cohort

The duration of continuous kidney replacement therapy (CKRT) represents a complex clinical surrogate reflecting the severity of systemic illness, the rate of metabolic recovery, and clinical decision-making regarding treatment discontinuation. The effect of CKRT duration on long-...

Beyond hypoxia: Context‐dependent transcriptional reprogramming by ERFVIIs

This Commentary highlights the finding that an increased post-submergence oxidative burst reprograms plant cysteine oxidase (PCO)-group VII ethylene response factor (ERFVII) oxygen sensing, inhibiting PCO activity and transcriptionally rewiring ERFVIIs toward oxidative stress rec...

The loss of COP1 delays senescence and inhibits root growth through modulation of sucrose allocation and availability.

CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) participates in diverse signaling pathways that regulate plant growth and development, but its role in sucrose-mediated signaling remains unclear. Here, we show that COP1 contributes to leaf senescence and root growth by modulating sucrose a...

Small Rotation Blocks and the Order-Six Stable Marriage Problem

We prove that a finite poset with at most fifteen elements, width at most three, and the following common-incomparability property has at most 48 antichains: for every x < y, the elements incomparable with both x and y form a chain of size at most two. An explicit fifteen-element...

Incorporating spatio-temporal population dynamics into deep learning models for small-area population forecasting

Small-area population forecasting has become increasingly critical for establishing localized policies to address regional demographic disparities. Due to its minimal data requirements and methodological simplicity, trend extrapolation offers a practical approach given the limite...

Thalamic projections from the cerebellar nuclei receiving proprioceptive signals from the jaw muscles in rats

The neural mechanisms involved in transmission of proprioceptive information from muscles are not fully understood. Proprioceptive signals from jaw-closing muscle spindles (jcms) are relayed to the supratrigeminal nucleus (Su5), and, then, from the Su5 to the thalamus including t...

Association between Glycemic Control and Survival in Patients with Type 2 Diabetes on Peritoneal Dialysis

Background: Diabetes is the leading cause of kidney failure globally affecting 40% of people receiving peritoneal dialysis (PD). High quality data on the potential impact of improving glycemic control is needed to inform the current recommendations to individualise HbA 1C targets...

Modular Control of Glass Transition and Transparency in ROMP-Derived Oxanorbornene Polymers

Abstract Achieving both high optical transparency and high glass-transition temperature (Tg) remains challenging in cyclic olefin polymers. Here, ring-opening metathesis polymerization (ROMP)-derived oxanorbornene polymers enable modular tuning of these competing properties throu...

Patient-Derived Transcriptomics Reveals Distinct Associated IFNγ-Myeloid States and Mitochondrial Complex I Programs in Rheumatoid Arthritis and Osteoarthritis

Background/Objectives: Macrophages are key contributors to the pathogenesis of rheumatoid arthritis (RA) and osteoarthritis (OA), but their disease-associated immunometabolic states remain incompletely understood. Methods: Here, we comparatively analyzed patient-derived transcrip...

Physicomechanical Properties and Crown Fracture Load of 3D-Printed Resins, a Milled Resin Composite, and Lithium Disilicate Glass-Ceramic: An In Vitro Comparative Study

This in vitro study compared the physicomechanical properties and crown fracture load (CFL) of three additively manufactured (AM) resins for definitive crowns (C&B Permanent [CB], CROWNTEC [CT], and VarseoSmile Crown plus [VS]), a milled resin composite (SHOFU HC [HC]), and lithi...

A Transient Left Atrial Appendage Filling Defect During Anticoagulation Interruption After Ischemic Stroke with Progressive Hemorrhagic Transformation: A Case Report

Background and Clinical Significance: Anticoagulation timing after atrial fibrillation (AF)-related ischemic stroke is uncertain when hemorrhagic transformation (HT) is progressive. Although early direct oral anticoagulant (DOAC) initiation is supported in selected patients, evid...
