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...

Synthesis and Direct Ink Writing of doped β-tricalcium phosphate bioceramics for bone repair applications

Marie Lasgorceix, Nicolas Somers, Florian Jean, Nicolas Preux, Cathy Delmotte, Laurent Boilet, Fabrice Petit, Anne Leriche

Introduction β-tricalcium phosphate (β-TCP, β-Ca3(PO4)2) is one of the most attractive biomaterials for bone regeneration and β-TCP macroporous scaffolds are highly promising for bone tissue engineering. Direct Ink Writing (DIW), an additive manufacturing process based on the extrusion of a...

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...

Stability results on the Kirchhoff plate equation with delay terms on the dynamical boundary controls

Mohammad Akil, Haidar Badawi, Serge Nicaise, Ali Wehbe

In this paper, we consider the Kirchhoff plate equation with delay terms on the dynam- ical boundary controls. We prove its well-posedness, strong stability, non-exponential stability, and polynomial stability under a multiplier geometric control condition.

Minimal δ(2)-ideal Lagrangian submanifolds and the quaternionic projective space

Kristof Dekimpe, Joeri van der Veken, Luc Vrancken

We construct an explicit map from a generic minimal δ(2)-ideal Lagrangian submanifold of Cn to the quaternionic projective space HPn−1, whose image is either a point or a minimal totally complex surface. A stronger result is obtained for n=3, since the above mentioned map then provides a one-to-one...
