Barium titanate-enhanced mixed matrix membranes for dye removal: photocatalytic membrane regeneration

Fabrication of mixed matrix membranes (MMMs) with effective tuning of interfacial interactions between the nano additives and the polymer matrix is crucial for enhanced membrane filtration applications. In present work, the nano additive barium titanate (BTO) was blended with Pol...

Oxygen Vacancy Engineering for Enhanced Remanent Polarization and Memory Window in a-IGZO/HZO Ferroelectric Field-Effect Transistors

Abstract HfO2-derived ferroelectric field-effect transistors (FeFETs) are promising for nonvolatile memory and logic-in-memory applications owing to CMOS compatibility and low-voltage polarization switching. Amorphous InGaZnO (a-IGZO) is attractive for back-end-of-line compatible...

Korean Buddhist Temple Food: A Traditional Plant-Based Dietary Pattern Linking Gut Microbiota, Metabolic Health, and Mindful Living

Korean Buddhist temple food represents a traditional plant-based dietary practice rooted in Korean Buddhist monastic traditions and characterized by an emphasis on seasonal and minimally processed plant foods. Traditional temple-food practices generally exclude pungent vegetables...

Temperature-Associated Differences in Mortality Timing in WSSV-Exposed Penaeus monodon Under Additional AHPND and WSSV Challenge

Water temperature can affect the clinical expression of white spot syndrome virus (WSSV) disease. However, mortality patterns under the influence of directional temperature change remain unclear. Here, we evaluated 576 specimens of Penaeus monodon from a WSSV-positive cohort in a...

GSD-Conditioned Generalization of UAV-Trained Oriented Vehicle Detectors Toward Satellite-Relevant Spatial Sampling

This study examines how train–test ground sampling distance (GSD) mismatch affects UAV-based oriented vehicle detection under controlled source-scene and network-input conditions. Five datasets at 10, 15, 20, 25, and 30 cm/pixel were generated by direct downsampling from the same...

Synergistic Insecticidal Efficacy of the Natural Fumigant Methyl Benzoate Against Phosphine-Resistant Sitophilus oryzae

The widespread emergence of phosphine-resistant populations of stored-product pests, such as the rice weevil (Sitophilus oryzae), poses a significant challenge to effective grain protection. This study investigated the fumigation toxicity of methyl benzoate (MBe), an eco-friendly...

Time-step level sleep apnea detection using LSTM with adaptive thresholding in polysomnography

Sleep apnea is a prevalent disorder linked to severe health risks. Current diagnosis relies on manual polysomnographic (PSG) analysis, which is time-consuming and subjective. This study aims to develop an objective, automated framework for time-step level apnea detection. We prop...

Association of Estimated Arterial Stiffness with Collateral Status and Functional Outcome after Endovascular Thrombectomy: A Secondary Analysis of the OPTIMAL-BP Trial

PURPOSE: Estimated pulse wave velocity (ePWV) is a surrogate of arterial stiffness that may influence stroke outcomes and potentially affect collateral circulation. We examined the association of ePWV with collateral status and 3-month functional outcome after successful endovasc...

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...

Effect of Y addition on microstructure, tensile properties, and corrosion behavior of high-speed-extruded Mg–5Bi–3Al alloy

This study investigates the effect of Y addition on the microstructure, tensile properties, and corrosion behavior of high-speed-extruded Mg–5Bi–3Al (BA53) alloy. Y-free BA53 and Y-containing BAW53 x alloys ( x = 0.2, 0.5, and 1.0 wt.%) are extruded at a die-exit speed of 67 m/mi...

Spontaneous Reduction in Mitral Valve Regurgitation in Three Dogs With Severe Myxomatous Mitral Valve Disease: An Unusual Case Report

ABSTRACT Background Myxomatous mitral valve disease (MMVD), the most common heart disease in small‐breed dogs, is characterized by mitral regurgitation (MR) resulting from valvular degeneration, which may progress to left‐sided heart failure. This report describes the cases of th...

MuSC cultivation for cultured meat production: recent advances, current limitations, and future directions

Abstract Cultured meat is being investigated as a potential alternative to conventional livestock production by cultivating animal cells under controlled conditions to reproduce key components and structural characteristics of meat. Muscle stem cells (MuSCs), which proliferate, d...

Complete genome sequence of Cupriavidus sp. PB-02, a potential new species with putative ability to degrade PBAT, isolated from soil

Abstract Objectives Poly(butylene adipate-co-terephthalate) (PBAT) is a biodegradable copolyester increasingly used in agricultural mulch films, yet genomic resources for PBAT-degrading bacteria remain limited. This study reports the complete genome sequence of Cupriavidus sp. PB...

Combination strategy of photothermal therapy and targeted IFN-β mutein priming elicits a durable abscopal effect

Metastatic tumors remain difficult to cure due to frequent dissemination and recurrence. While photothermal therapy (PTT) can trigger abscopal effects, PTT monotherapy often fails to sustain systemic immunity. Here, we investigated a tripartite strategy combining PTT, a tumor-tar...
