We present a non-commutative algorithm for the multiplication of a 2x2-block-matrix by its transpose using 5 block products (3 recursive calls and 2 general products) over C or any finite field.We use geometric considerations on the space of bilinear forms describing 2x2 matrix products to obtain this algorithm and we show how to reduce the number ...
Due to large outbreaks observed worldwide, Candida auris has emerged as a major threat to healthcare facilities. To prevent these phenomena, a systematic screening should be performed in patients transferred from regions where the pathogen is highly endemic. In this study, we recorded and analyzed French mycologists' current knowledge and practice ...
ObjectivesThis study aims to understand a major result of ComCor, an online epidemiological study conducted to identify the circumstances of COVID-19 infection in France from 2020 to 2022: One third of respondents reported ignoring the circumstances of their infection.MethodsWe conducted a qualitative study through semi-structured interviews, diagn...
Flexible working time arrangements (FWTA) have increased over the last decades, favored by labor market deregulation, the decentralization of collective bargaining and the development of new technologies. The negative impact of some non-standard working hours on health (like night work, shift work) is quite well-known but other forms of FWTA have b...
Introduction: Urological consultations for erectile dysfunction (ED) are increasing worldwide. Penile prosthesis (PP) implantations are performed when other treatments are unsuccessful. However, there is no data regarding PP implantations in France beyond the year 2016.Objectives: This study aimed to describe the changes in the number and type of P...
En Hongrie, ils sont majoritaires au pouvoir. En Croatie, en Finlande, en Italie, aux Pays-Bas et en République tchèque, ils font partie de coalitions qui dirigent le pays. En Suède, en Allemagne, en Flandre, ils ont le vent en poupe. « Ils », ce sont les partis d’extrême droite. La façade est de plus en plus lisse, mais derrière elle se cache une ...
Botryosphaeriaceae species are the major causal agents of walnut dieback worldwide, along with Diaporthe species. Botryosphaeria dothidea and Neofusicoccum parvum are the only two Botryosphaeriaceae species associated with this recently emergent disease in France, and little is known about their diversity, structure, origin and dispersion in French...

The economic development of societies in Gaul during the Second Iron Age and the Roman period relied on agricultural system transformations. Hundreds of carpological studies carried out in the northern half of France over the last four decades have thoroughly documented the evolution of crop production and farming practices during this period. The ...
Après une première étude réalisée en 2013 (Boccarossa 2013 et Figuet et al. 2015), PatriNat assure le suivi de la satisfaction des usagers de l'INPN via une enquête chaque année depuis 2015 (hors 2021). Les objectifs principaux de ce suivi annuel sont de mieux cerner et de suivre l’évolution au fil des années des profils des utilisateurs de l’INPN,...

Global changes in climate are contributing to modified Phlebotomine sand fly presence and activity, and the distribution of the pathogens they transmit (e.g., Leishmania and Phlebovirus), and are leading to their possible extension toward northern France. To predict the evolution of these pathogens and control their spread, it is essential to ident...
