The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Improving vehicle re‐identification using CNN latent spaces: Metrics comparison and track‐to‐track extension

open access: yesIET Computer Vision, 2021
Herein, the problem of vehicle re‐identification using distance comparison of images in CNN latent spaces is addressed. First, the impact of the distance metrics, comparing performances obtained with different metrics is studied: the minimal Euclidean ...

Gallium‐Catalyzed Tandem Carbonyl–Olefin Metathesis/Dehydrogenative Coupling Enables Rapid Access to Cyclopentenes

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
A cationic gallium(III) catalyst enables rapid construction of substituted cyclopentenes via tandem carbonyl‐ene metathesis/Friedel–Crafts coupling. Electronic tuning of alcohol electrophiles allows access to diverse, densely functionalized rings in a single operation.

Conformal Metrics to a Product or Doubly Warped Product on S2×S2 and the Hopf Conjecture

open access: yesJournal of Mathematics, 2022
Hopf’s well-known conjecture states that there exists no metric of positive sectional curvature in the product manifold S2×S2. In this paper, we show that the Hopf conjecture is true for conformal metrics to the product metric or doubly warped products ...

La formalisation du discours savant La formalisation du discours savant

open access: yesDigithum, 1999
Les sciences de I’homme sont-elles en crise? Beaucoup l’affirment, périodiquement, au fil des décennies. Je n’ai quant á moi aucune opinion tranchée sur ce point: mon domaine de recherche se limitant á l’archéologie, je ne me sens guére armé pour traiter

Convection‐Permitting Regional Climate Simulations Reveal Stronger Drying and Snow Loss in Semi‐Arid Mountainous Basins of Morocco

open access: yesHydrological Processes, Volume 40, Issue 6, June 2026.
Convection‐permitting simulations (WRF3, 3 km) better represent mountain precipitation and snow processes than coarser regional simulations (WRF20, 20 km). Hydrological simulations forced by WRF3 improve streamflow seasonality and snow‐related hydrological signatures compared to WRF20.

Changing trends in prenatal screening and treatment of cytomegalovirus infection in France: 7‐year national cohort study (2017–2023)

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 756-763, June 2026.
ABSTRACT Objectives Cytomegalovirus (CMV) is the leading cause of congenital infectious neurosensory impairment. We aimed to present national epidemiological data on maternal CMV infection during pregnancy in France, focusing in particular on primary infection in the periconceptional period or first trimester, and to assess the impact of changes in ...
