Strained two-dimensional tungsten diselenide for mechanically tunable exciton transport.

Tightly bound electron-hole pairs (excitons) hosted in atomically-thin semiconductors have emerged as prospective elements in optoelectronic devices for ultrafast and secured information transfer. The controlled exciton transport in such excitonic devices requires manipulating potential energy gradient of charge-neutral excitons, while electrical gating or nanoscale straining have shown limited efficiency of exciton transport at room temperature. Here, we report strain gradient induced exciton transport in monolayer tungsten diselenide (WSe) across microns at room temperature via steady-state pump-probe measurement.

An Energy-Efficient Dynamic Feedback Image Signal Processor for Three-Dimensional Time-of-Flight Sensors.

With the recent prominence of artificial intelligence (AI) technology, various research outcomes and applications in the field of image recognition and processing utilizing AI have been continuously emerging. In particular, the domain of object recognition using 3D time-of-flight (ToF) sensors has been actively researched, often in conjunction with augmented reality (AR) and virtual reality (VR). However, for more precise analysis, high-quality images are required, necessitating significantly larger parameters and computations.

Facile Formation of Metallic Surface with Microroughness via Spray-Coating of Copper Nanoparticles for Enhanced Liquid Metal Wetting.

This paper presents a simple, fast, and cost-effective method for creating metallic microstructured surfaces by spray-coating a dispersion of copper nanoparticles (CuNPs) onto polymethyl methacrylate (PMMA) substrates, enabling the imbibition-induced wetting of liquid metal. The formation of these microstructured patterns is crucial for the spontaneous wetting of gallium-based liquid metals. Traditional techniques for producing such microstructures often involve complex and costly lithography and vacuum deposition methods.

Sex differences in lipid mediators derived from omega-3 fatty acids in older individuals with low-grade chronic inflammation.

The rate of cardiovascular disease (CVD) death is higher in men than women before age 50 y, but the gap between sexes significantly narrows after menopause. Lipid mediators derived from EPA, DHA and AA play a role in inflammation and CVD. The aim of our study was to assess whether plasma concentrations of these lipid mediators differ between postmenopausal women and men.

Determinants of quality of life and emotional well-being in a bariatric surgery seeking cohort of 1501 multi-ethnic Asian patients.

Objective: The relationship between ethnicity, obesity and health-related quality of life outcomes in a multi-ethnic population remains poorly understood. We aim to investigate the relationship between ethnicity, body mass index (BMI), obesity-associated diseases, as well as determinants of quality of life (QoL) in Southeast Asian patients with obesity. We aim to develop and validate a simple objective score to identify patients with obesity at high risk for major depression.

Aligning Large Language Models for Enhancing Psychiatric Interviews Through Symptom Delineation and Summarization: Pilot Study.

Background: Recent advancements in large language models (LLMs) have accelerated their use across various domains. Psychiatric interviews, which are goal-oriented and structured, represent a significantly underexplored area where LLMs can provide substantial value. In this study, we explore the application of LLMs to enhance psychiatric interviews by analyzing counseling data from North Korean defectors who have experienced traumatic events and mental health issues.

IQGAP3 signalling mediates intratumoral functional heterogeneity to enhance malignant growth.

Background: The elevation of IQGAP3 expression in diverse cancers indicates a key role for IQGAP3 in carcinogenesis. Although IQGAP3 was established as a proliferating stomach stem cell factor and a regulator of the RAS-ERK pathway, how it drives cancer growth remains unclear.

Objective: We define the function of IQGAP3 in gastric cancer (GC) development and progression.

Antibiotic stewardship bundle for uncomplicated gram-negative bacteremia at an academic health system: a quasi-experimental study.

Objective: To evaluate whether an antimicrobial stewardship bundle (ASB) can safely empower frontline providers in the treatment of gram-negative bloodstream infections (GN-BSI).

Intervention And Method: From March 2021 to February 2022, we implemented an ASB intervention for GN-BSI in the electronic medical record (EMR) to guide clinicians at the point of care to optimize their own antibiotic decision-making. We conducted a before-and-after quasi-experimental pre-bundle (preBG) and post-bundle (postBG) study evaluating a composite of in-hospital mortality, infection-related readmission, GN-BSI recurrence, and bundle-related outcomes.

Precision medicine in axial spondyloarthritis: current opportunities and future perspectives.

Axial spondyloarthritis (axSpA) is a complex disease characterized by a diverse range of clinical presentations. The primary manifestation is inflammatory lower back pain, often accompanied by other clinical manifestations such as peripheral arthritis, enthesitis, uveitis, psoriasis, and inflammatory bowel disease. However, the presentation of axSpA can vary widely among patients.

Forced air oscillations - pneumatic capacitance in microfluidic oscillators produces non-linear responses and emergent behaviors.

Pneumatic control mechanisms have long been integral to microfluidic systems, primarily using solenoid valves, pressurized gases, and vacuums to direct liquid flow. Despite advancements in liquid-driven self-regulated microfluidic circuits, gas-driven systems leveraging fluid compressibility remain underexplored. This study presents a mathematical and experimental investigation of gas-driven microfluidic circuits, focusing on forced-air oscillators.

Phase I PIANO trial-PIPAC-oxaliplatin and systemic nivolumab combination for gastric cancer peritoneal metastases: clinical and translational outcomes.

Introduction: Pressurized intraperitoneal aerosol chemotherapy-oxaliplatin (PIPAC-OX) induces direct DNA damage and immunogenic cell death in patients with gastric cancer peritoneal metastases (GCPM). Combining PIPAC-OX with immune checkpoint inhibition remains untested. We conducted a phase I first-in-human trial evaluating the safety and efficacy of PIPAC-OX combined with systemic nivolumab (NCT03172416).

Amentoflavone from inhibits SARS-CoV-2 RNA-dependent RNA polymerase.

The SARS-CoV-2 pandemic caused millions of deaths due to its prominent infectivity and mortality. Although the vaccines and medicines for SARS-CoV-2 are on the market, new coronavirus variants like influenza are expected to reemerge continuously. Therefore, effective and inexpensive medicines will be required to respond to SARS-CoV-2 variants.

DNA damage drives antigen diversification through mosaic Variant Surface Glycoprotein (VSG) formation in .

Antigenic variation, using large genomic repertoires of antigen-encoding genes, allows pathogens to evade host antibody. Many pathogens, including the African trypanosome , extend their antigenic repertoire through genomic diversification. While evidence suggests that depends on the generation of new variant surface glycoprotein (VSG) genes to maintain a chronic infection, a lack of experimentally tractable tools for studying this process has obscured its underlying mechanisms.

Purcell Enhancement and Spin Spectroscopy of Silicon Vacancy Centers in Silicon Carbide Using an Ultrasmall Mode-Volume Plasmonic Cavity.

Silicon vacancy (V) centers in 4H-silicon carbide have emerged as a strong candidate for quantum networking applications due to their robust electronic and optical properties, including a long spin coherence lifetime and bright, stable emission.
