Extended KAFR: a kinematic-adaptive paradigm for the efficient analysis of surgical video

Abstract Artificial Intelligence is increasingly applied to surgical video analysis for phase segmentation, skill assessment, and workflow optimization. A key challenge is the length of surgical recordings, often one to several hours, creating a substantial computational burden....

Association between respiratory phenotypes and successful ventilator liberation in early-onset and late-onset ARDS: a multicenter cohort study

Early-onset and late-onset acute respiratory distress syndrome (ARDS) differ in clinical course and outcomes, but their longitudinal respiratory trajectories remain unclear. We aimed to characterize respiratory trajectories in early- and late-onset ARDS and identify trajectory-ba...

Metabolic pathways are associated with increased estimated cardiovascular risk in major depressive disorder: a QRISK3-based analysis

Background Depression and anxiety are among the most commonly encountered disorders in psychiatric practice. Previous studies have shown that both cardiovascular disease and cardiovascular risk are increased in these disorders. This study aimed to investigate the potential relati...

Trends in Healthcare-Associated Infections and Antimicrobial Use in a Paediatric Hospital from Bucharest, Romania, Across the Pre-Pandemic, Pandemic, and Post-Pandemic Periods (2017–2024)

The COVID-19 pandemic and the broader epidemiological context may have affected healthcare-associated infections (HAIs) and antimicrobial use (AU), including among the paediatric population. This study used seven point prevalence surveys (PPSs) to characterise HAIs and AU and to...

Biofilm presence and substrate type influence oyster larval settlement and survival

ABSTRACT Marine invertebrates with a bipartite life cycle typically undergo a developmental transition from pelagic larvae to benthic juveniles. The success of this transition largely depends on appropriate habitat and substrate selection, which is crucial for completing metamorp...

Interest of luspatercept in treatment of anemia in lower-risk of myelodysplastic syndrome anemia: a single center study of 26 patients

Myelodysplastic syndromes (MDS) are heterogeneous clonal hematological disorders characterized by ineffective hematopoiesis resulting in peripheral cytopenias. Luspatercept, an erythroid maturation agent, represents a novel therapeutic option for the management of anemia associat...

A Virtual Resistance-Capacitance Control Strategy for Mitigating Consecutive Commutation Failures in Weak Receiving-End HVDC Systems

In view of the high susceptibility of weak receiving-end High-Voltage Direct Current (HVDC) systems to consecutive commutation failures during AC faults on the inverter side, a novel virtual resistance-capacitance control strategy is proposed. This strategy is designed to suppres...

Nonlinear dynamic modeling and parameter identification of air springs in the ultra-low frequency range considering thermal hysteresis

The nonlinear dynamic performance of a constrained rolling-lobe air spring (CRLAS) is measured using a servo-controlled hydraulic test rig. Experimental results indicate that in the ultra-low frequency range (0.002–1 Hz), the dynamic stiffness increases sharply, while the loss an...

Ageing in fear: unraveling the links between elder abuse, social isolation and mental health outcomes

Purpose The present study aims to examine the relationship between elder abuse and depressive symptoms among older adults. In addition, the study examines the mediating role of loneliness in explaining the above relationship. Design/methodology/approach The present study adopts c...

Selective Hydrogenation of Styrene to Ethylbenzene over a Pd/Cu(111) Single-Atom Alloy Surface

Abstract The hydrogenation of styrene (C6H5CH═CH2) to ethylbenzene (C6H5CH2CH3) over a 0.1 ML Pd/Cu(111) single-atom alloy (SAA) surface was investigated under ambient pressure conditions using polarization-dependent reflection absorption infrared spectroscopy (PD-RAIRS). Gas-pha...

In vitro activity of gepotidacin against baseline Neisseria gonorrhoeae phenotypes and genotypes recovered from a clinical trial for uncomplicated urogenital gonorrhea (EAGLE-1)

ABSTRACT There is an urgent need for novel antimicrobials to treat multidrug-resistant strains of Neisseria gonorrhoeae . In a phase III trial (EAGLE-1), gepotidacin, a first-in-class triazaacenaphthylene antibacterial, demonstrated non-inferiority to ceftriaxone plus azithromyci...

Observed Clinical and Operational Factors Are Associated with Biomarker Test Utilization in Respiratory Virus RT-PCR Testing: A Real-World Analysis of Inflammatory, Cardiac, and Thrombotic Biomarkers

Background/Objectives: Routinely collected biomarker data are generated through selective testing. We examined associations of observed clinical and operational factors with biomarker availability and explored the incremental discrimination provided by biomarker concentrations fo...

Integrated Upcycling of Rice Straw into Electrospun Nanocellulose Chemiresistors and Lignin Nanoparticles with Superior Photoprotection

Abstract Open-field burning of rice straw, an abundant source of renewable biomacromolecules, remains a major environmental and public health concern. Herein, we report an integrated upcycling strategy that simultaneously valorizes rice-straw-derived cellulose and lignin into hig...

Wafer-scale synthesis of WSe 2 for high-performance p-type top-gated transistors and logic circuits

Two-dimensional (2D) transition metal dichalcogenides (TMDs) offer a promising pathway for next-generation electronics due to their exceptional electrical characteristics at atomically thin thickness. Nevertheless, the realization of high-quality p-type 2D-FETs remains a signific...

The one-Layer Antarctic model for Dynamical Downscaling of Ice–ocean Exchanges (LADDIE) version 2.0

Projections of Antarctic mass loss and its contribution to sea-level rise are highly sensitive to the applied ocean-driven melting. As fully coupled continental-scale ocean–ice sheet models are scarce, ice sheet models are typically run in standalone configurations, forced with p...

A nuclear terrorism scenario: improvised nuclear weapons with 60%-enriched uranium

In this work we show that approximately 60–70 kg of 60%-enriched uranium can be used to build a crude nuclear weapon with a kiloton yield. While too large to fit on a missile, such a weapon could be delivered by a shipping container. This analysis is motivated by the June 2025 Is...

Preoperative Antibiotic Administration Before Distal Radius Fracture ORIF and Postoperative Outcomes: A Propensity-Matched Cohort Study

Purpose Surgical site infections following certain hand surgery procedures are inherently low; however, the utility of prophylactic antibiotics in such scenarios remains a point of controversy. This study aimed to evaluate postoperative infection rates among patients who were pre...

Characteristics of Clinical Profiles in Psoriatic Arthritis Patients Initiating Ustekinumab by a Dermatologist or Rheumatologist

Introduction Psoriatic Arthritis (PsA), an inflammatory disease, is primarily associated with Psoriasis (PsO). This study assesses the collaboration between rheumatologists and dermatologists in PsA diagnosis and disease management. It also describes the clinical profiles of pati...

Business environmental innovation and circular economy practices: global evidence from corporate waste recycling

This study examines the role of business environmental innovation in advancing circular economy practices, with a particular focus on corporate waste recycling. Using a large sample of publicly listed firms from 41 countries over the period of 2007–2024, we provide robust empiric...

A microeconomic perspective on the cash-flow endogeneity in terminal value models

Abstract This paper studies how treating free cash flow (FCF) as endogenous—shaped by a firm’s investment choices—changes terminal value calculations. In practice, analysts address the uncertainty and ambiguity of the perpetual growth rate g and the cost of capital r with sensiti...
