Three-dimensional experimental investigation of the interaction between a rising bubble and a vortex ring

The interaction between turbulent flows and bubbles is a complex phenomenon ubiquitous in natural and industrial settings. In this work, we experimentally investigate, from a fundamental perspective, the interaction between a rising bubble and a vortex ring in counterflow. Using...

Drug allergy de-labelling with a direct oral challenge in outpatient hospital visits

Abstract Although direct oral challenge has been adopted by numerous clinicians worldwide in the context of drug hypersensitivity, drug allergy de-labelling remains largely confined to inpatient or outpatient hospital-based care,mostly for penicillins. In this study, we aim to pe...

Adsorption at Interfaces and Contact Lines: From Molecular Oversolubility to Macroscopic Wetting

Abstract Interfaces between two phases and contact lines between three phases are the locus of complex phenomena that govern the thermodynamic and dynamic behavior of such systems─both at the microscopic and macroscopic scales. Yet, despite the abundant literature on the topic, t...

A cytidine deaminase biodegrader sensitises multiple cancer types to deoxycytidine analogue-based chemotherapies

Abstract Deoxycytidine (dC) analogues are widely used to treat solid tumours and blood cancers. However, their clinical efficacy is often limited by resistance mediated by cytidine deaminase (CDA), which converts these drugs into inactive metabolites. Existing CDA inhibitors have...

Violence and vulnerability among women attending a hospital forensic medical unit in France: a cross-sectional study using hierarchical cluster analysis

Violence against women remains a global public health priority. Forensic Medical Units (FMUs) offer a critical setting to examine vulnerability profiles among victims, yet few studies have characterised the interplay between violence types, perpetrator relationships, and associat...

Semaglutide for Treating Paediatric Craniopharyngioma‐Related Obesity: A Multicentre Case Series

ABSTRACT Aims Obesity is a complication of childhood craniopharyngioma that remains difficult to treat. We investigated whether semaglutide was associated with a decrease in BMI among adolescents with craniopharyngioma‐related obesity. Material and Methods This multicentre retros...

Soft-Templated Carbon Models Elucidate the Anomalous Increase of Capacitance in Nanopores

Abstract Supercapacitors are electrochemical energy-storage devices distinguished by rapid charge–discharge and high power density. The observation of anomalously enhanced capacitance in nanoporous carbons challenged classical descriptions of double-layer charging and stimulated...

Uncertainties of GRACE/GRACE-FO Satellite Gravimetry Data and Thereof Derived Products

Abstract Inter-satellite ranging by space gravimetry missions, such as from the Gravity Recovery And Climate Experiment (GRACE) mission and its successor mission GRACE Follow-On, has been established to observe mass variations in the Earth system from space globally. A complex pr...

Mechanism‐Guided Engineering of Upconversion Nanoparticles for Antibacterial Phototherapy: From Photonic Principles to Translational Nanosystems

The emergence of multidrug-resistant (MDR) bacteria necessitates the development of next-generation antimicrobial strategies beyond conventional antibiotics. Upconversion nanoparticles (UCNPs), owing to their anti-Stokes luminescence under near-infrared (NIR) excitation, offer a...

Serum GFAP and Age Accurately Distinguish AQP4 ‐ IgG Positive and Double Seronegative NMOSD From MOGAD After a Recent Attack

BACKGROUND: Serum neurofilament-light chain (sNfL) and glial fibrillary acidic protein (sGFAP) are associated with multiple sclerosis (MS) activity. This study aimed to identify patient- and disease-level determinants of sNfL and sGFAP and to evaluate their ability to support dif...

Exposure to Guideline-Recommended Quadruple Therapy after First Hospitalisation for HFrEF in France

Abstract Introduction In 2021, the European Society of Cardiology updated its guidelines for managing heart failure with reduced left ventricular ejection fraction (HFrEF), recommending a four-drug regimen combining an SGLT2 inhibitor, a beta-blocker, a mineralocorticoid receptor...

Incorporating sliding and local rigidity constraints in neural-based image registration

Image registration is widely used in various applications to estimate the deformations of moving structures in image pairs acquired at different times. Spatial regularization strategies often take a one-size-fits-all approach by imposing uniform deformation constraints across the...

Mechanisms of Cyclonic Meander Formation in the Western Yucatan Channel

Cyclonic meanders in the western Yucatan Channel generate intense frontal conditions associated with strong isopycnal uplift, enhanced vertical shear, and local transformation of Caribbean waters into Yucatan Gulf Common Water. Observational composites further show that strong me...

AI Consciousness and Existential Risk

In AI, existential risk denotes the hypothetical threat posed by an artificial system that would possess both the capability and the objective, either directly or indirectly, to eradicate humanity. This issue is gaining prominence in scientific debate due to recent technical adva...

Grape yield estimation using on-the-fly MIMO millimeter-wave radar at operational field speed: A variety-dependent proof of concept

Accurate pre-harvest grape yield estimation is a critical challenge in precision viticulture, yet current optical approaches (RGB cameras, LiDAR) are fundamentally limited by foliage occlusion and sensitivity to ambient lighting conditions. This paper presents a ground-based grap...

Mechanical Thrombectomy Versus Medical Management for Large Ischemic Core Stroke Identified before Inter‐Hospital Transfer: A Post Hoc Analysis of the LASTE Trial

Objective This study assessed the efficacy of thrombectomy in acute ischemic stroke because of large‐vessel occlusion (AIS‐LVO) initially admitted to primary stroke centers (PSC) and subsequently transferred to a comprehensive stroke center (CSC), with a large ischemic core ident...

A predictive coding framework for safe and versatile control of supernumerary robotic limbs

Supernumerary robotic limbs (SLs) have the potential to extend human sensorimotor capabilities by increasing effective degrees of freedom. However, current systems are designed for a single task and cannot flexibly coordinate with natural limbs (NLs). Here we propose a hierarchic...
