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...

Integrated adipose tissue transcriptomic and miRNA remodeling identifies molecular pathways associated with residual cardiovascular risk after weight loss

Abstract Background Weight loss improves cardiometabolic health, yet substantial inter-individual variability remains in residual cardiovascular risk. Here, we investigated whether post-weight loss adipose tissue (AT) molecular remodeling is associated with this variability. Meth...

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...

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...

Another regularizing property of the 2D eikonal equation

A weak solution of the two-dimensional eikonal equation amounts to a vector field m:Ω⊂R2→R2 such that |m|=1 a.e. and divm=0 in D′(Ω). It is known that, if m has some low regularity, e.g., continuous or W1/3,3, then m is automatically more regular: locally Lipschitz outside a loca...

Ontogenic dynamics of phenotypic diversity in savanna mahogany (Khaya senegalensis) across three sites in Côte d’Ivoire

This study aimed to assess the morphological variability of savanna mahogany ( Khaya senegalensis ) through an ontogenic approach across three natural stands Kouassi-N’Dawa, Koumokro, and Pouniakele subjected to contrasting environmental conditions in Côte d’Ivoire. On each site,...

Swarming by curvature control in arbitrary dimension

We consider an interacting particle system proposed in the literature to model fish behavior. In this model, the agents move at constant speed and control the curvature of their trajectory (i.e. the time-derivative of their velocity) so as to align their velocity with that of the...

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate...

Use of cardiac magnetic resonance imaging after hospitalization for acute heart failure: insights from the French nationwide OFICA-2 cohort

Abstract Background Cardiac magnetic resonance (CMR) has a central role in the management of patients with acute heart failure (AHF), but timely access remains heterogeneous. We investigated real-world CMR use in patients hospitalized for AHF and its associations with demographic...

Ground states on a fractured strip and one-dimensional reduction

We consider the nonlinear Schrödinger equation on a strip with Neumann boundary conditions and a delta condition at x = 0 . We first show the existence of ground states as minimizers of the action or of the energy under suitable constraints. We then prove that the energy minimize...

Fast and Scalable Air Quality Neural Emulator for High‐Resolution Predictions on Very Large Domains

Abstract This research explores the development and implementation of SIRANet, an advanced deep learning‐based emulator designed for fine‐scale air quality modeling. Leveraging the computational efficiency of neural networks, SIRANet builds upon the established SIRANE atmospheric...

Refinements on higher order Weil–Oesterlé bounds via a Serre type argument

Abstract Weil's theorem gives the most standard bound on the maximum number of points of a curve of genus over a finite field . This bound was improved by Ihara and Oesterlé for larger genus. A recent point of view allows one to recover these bounds by solving a sequence of semi‐...

Convergence Rates for Polynomial Optimization on Set Products

Abstract. We consider polynomial optimization problems on Cartesian products of basic compact semialgebraic sets. The solution of such problems can be approximated as closely as desired by hierarchies of semidefinite programming relaxations, based on classical sums of squares cer...

One‐Year Transcutaneous Tibial Nerve Stimulation Treatment Persistence in Lower Urinary Tract Dysfunction: Clinical and Urodynamic Associated Factors in a Prospective Observational Study

AIMS: To assess 1-year Transcutaneous Tibial Nerve Stimulation (TTNS) treatment persistence in routine clinical care and to explore clinical and urodynamic factors associated with treatment persistence in patients with lower urinary tract dysfunction (LUTD). METHODS: A prospectiv...
