A Python Toolbox for Data-Driven Aerodynamic Modeling Using Sparse Gaussian Processes, Une boîte à outils Python pour la modélisation aérodynamique basée sur les données à l'aide de processus gaussiens creux

Hugo Valayer, Nathalie Bartoli, Mauricio Castaño-Aguirre, Rémi Lafage, Thierry Lefebvre, Andrés López-Lopera, Sylvain Mouton

In aerodynamics, characterizing the aerodynamic behavior of aircraft typically requires a large number of observation data points. Real experiments can generate thousands of data points with suitable accuracy, but they are time-consuming and resource-intensive. Consequently, conducting real…

Virome release of an invasive exotic plant species in southern France

Oumaima Moubset, Denis Filloux, Hugo Fontes, Charlotte Julian, Emmanuel Fernandez, Serge Galzi, Laurence Blondin, Sélim Ben Chehida, Jean-Michel Lett, François Mesléard, Simona Kraberger, Joy M Custer, Andrew Salywon, Elizabeth Makings, Armelle Marais, Frédéric Chiroleu, Pierre Lefeuvre, Darren P Martin, Thierry Candresse, Arvind Varsani, Virginie Ravigné, Philippe Roumagnac

The increase in human-mediated introduction of plant species to new regions has resulted in a rise of invasive exotic plant species (IEPS) that has had significant effects on biodiversity and ecosystem processes. One commonly accepted mechanism of invasions is that proposed by the enemy release…

Densification of hydroxyapatite through cold sintering process: Role of liquid phase chemistry and physical characteristic of HA powder

Muthusundar Kumar, Mohamed Aymen Ben Achour, Marie Lasgorceix, Paulo Quadros, Rosica Mincheva, Jean-Marie Raquez, Anne Leriche

Hydroxyapatite is a well-known bioactive material widely employed in bone regeneration applications. Densifying hydroxyapatite at the nanoscale remains challenging with conventional sintering methods. This investigation focuses on the densification of commercially available nano-hydroxyapatite…

Discrete Gagliardo-Nirenberg inequality and application to the finite volume approximation of a convection-diffusion equation with a Joule effect term

Caterina Calgaro, Clément Cancès, Emmanuel Creusé

A discrete order-two Gagliardo–Nirenberg inequality is established for piecewise constant functions defined on a two-dimensional structured mesh composed of rectangular cells. As in the continuous framework, this discrete Gagliardo–Nirenberg inequality allows to control in particular the $L^4$ norm…

On G1 and G2 Hermite interpolation by spatial Algebraic-Trigonometric Pythagorean Hodograph curves with polynomial parametric speed, Interpolation de Hermite G1 et G2 par des courbes spatiales Algébrique-Trigonométrique à Hodographe Pythagorien

Thierry Bay, Isabelle Cattiaux-Huillard, Lucia Romani, Laura Saini

In this paper we focus on the class of Algebraic-Trigonometric Pythagorean Hodograph curves (ATPH for short) that is characterized by a purely polynomial parametric speed. Within such a class of ATPH curves, we first construct interpolants to spatial G1 Hermite data equipped with curvature values.…, Dans cet article, nous nous concentrons sur la classe des courbes Algébrique-Trigonométrique à Hodographe Pythagorien (ATPH) qui est caractérisée par une vitesse paramétrique purement polynomiale. À partir de ces courbes ATPH, nous construisons tout d'abord des interpolants pour résoudre le…

Emergence of the Dickeya genus involved duplication of the OmpF porin and the adaptation of the EnvZ-OmpR signaling network

Clémence Cochard, Marine Caby, Peggy Gruau, Edwige Madec, Michael Marceau, Iulia Macavei, Jérôme Lemoine, Chrystelle Le Danvic, Franck Bouchart, Brigitte Delrue, Sébastien Bontemps-Gallo, Jean-Marie Lacroix

Genome evolution, and more specifically gene duplication, is a key process shaping host–microorganism interaction. The conserved paralogs usually provide an advantage to the bacterium to thrive. If not, these genes become pseudogenes and disappear. Here, we show that during the emergence of the…

A Residue Formula for Meromorphic Connections and Applications to Stable Sets of Foliations

Masanori Adachi, Séverine Biard, Judith Brinkschulte

We discuss residue formulae that localize the first Chern class of a line bundle to the singular locus of a given holomorphic connection. As an application, we explain a proof for Brunella’s conjecture about exceptional minimal sets of codimension one holomorphic foliations with ample normal bundle…

Exponential stability and exact controllability of a system of coupled wave equations by second-order terms (via Laplacian) with only one non-smooth local damping

Mohammad Akil, Zayd Hajjej

The purpose of this work is to investigate the exponential stability of a second-order coupled wave equations by Laplacian with one locally internal viscous damping. The strong stability is established by combining a unique con- tinuation result and a Carleman estimate. Besides, the exponential…

A N-dimensional elastic$$\backslash $$viscoelastic transmission problem with Kelvin–Voigt damping and non smooth coefficient at the interface

Mohammad Akil, Ibtissam Issa, Ali Wehbe

We investigate the stabilization of a multidimensional system of coupled wave equations with only one Kelvin–Voigt damping. Using a unique continuation result based on a Carleman estimate and a general criteria of Arendt–Batty, we prove the strong stability of the system in the absence of the…
