Stability for Degenerate Wave Equations with Drift Under Simultaneous Degenerate Damping

Mohammad Akil, Genni Fragnelli, Ibtissam Issa

In this paper we study the stability of two different problems. The first one is a one-dimensional degenerate wave equation with degenerate damping, incorporating a drift term and a leading operator in non- divergence form. In the second problem we consider a system that couples degenerate and non-...

Biomatériaux céramiques et lutte contre les infections nosocomiales en chirurgie ostéo-articulaire, Ceramic biomaterials and fight against nosocomial in joint and bone surgery

Franck Bouchart

Depuis plusieurs décennies, les céramiques à base de phosphate de calcium (hydroxyapatite et phosphate tricalcique β) ont été utilisées comme substitut afin de remplacer les défauts osseux en chirurgie ostéo-articulaire du fait de leur composition minérale similaire à celle de l'os et de leur..., For several decades, the calcium phosphate based ceramics (hydroxyapatite and β-tri-calcium phosphate) are used as substitutes for replacing bone defects in bone and joint surgery because their mineral composition is similar to bone and exhibit a very good bio-activity. Currently, two problems...

Metric subregularity and ω(•)-normal regularity properties

Florent Nacry, Vo Anh Thuong Nguyen, Juliette Venel

In this paper, we establish through an openness condition the metric subregularity of a multimapping with normal ω(•)-regularity of either the graph or values. Various preservation results for prox-regular and subsmooth sets are also provided.

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...
