Stability properties of dissipative evolution equations with nonautonomous and nonlinear damping

Serge Nicaise

In this paper, we obtain some stability results of (abstract) dissipative evolution equations with a nonautonomous and nonlinear damping using the exponential stability of the retrograde problem with a linear and autonomous feedback and a comparison principle. We then illustrate our abstract…

MULTIPLE BOUNDED VARIATION SOLUTIONS FOR A PRESCRIBED MEAN CURVATURE EQUATION WITH NEUMANN BOUNDARY CONDITIONS

Alberto Boscaggin, Francesca Colasuonno, Colette De Coster

We prove the existence of multiple positive BV-solutions of the Neumann problem - (u'/\sqrt{1+{u'}^2})' = a(x)f (u) in (0, 1), u (0) = u (1) = 0, where a(x) > 0 and f belongs to a class of nonlinear functions whose prototype example is given by f (u) = −λu + u^p, for λ > 0 and…

Under pressure! Nudging electricity consumption within firms. Feedback from a field experiment

Christophe Charlier, Gilles Guerassimoff, Ankinée Kirakozian, Sandrine Selosse

Many economists and psychologists have studied the impact of nudges on households' pro-environmental behaviors. Interestingly, "private nudges'' can be imagined for companies. Yet, studies focusing on nudging employees' energy use are rare. The objective of our paper is to…

Bone-like ceramic scaffolds designed with bioinspired porosity induce a different stem cell response

Silvia Panseri, Monica Montesi, Dominique Hautcoeur, Samuele Dozio, Shaan Chamary, Eamonn de Barra, Anna Tampieri, Anne Leriche

Abstract Biomaterial science increasingly seeks more biomimetic scaffolds that functionally augment the native bone tissue. In this paper, a new concept of a structural scaffold design is presented where the physiological multi-scale architecture is fully incorporated in a single-scaffold solution…

Zirconia ceramics, structure and properties

Anne Leriche, Francis Cambier, Helen Reveron

This article gives an introductory review on zirconia by describing its crystallographic, physical and chemical properties. Developed since the 1980s following the discovery of stabilization at room temperature of its high temperature phases, zirconia has continued to fascinate scientists and…

Overview of Substitutes for Bone Replacement: Natural and Synthetic Products

Nicolas Somers, Marie Lasgorceix

This review provides an overview of materials from natural and synthetic origin, specifically in the field of bioceramics and bioglasses, applied to bone substitution. The different developmental approaches currently considered to improve the biological performance of these bone implants, mainly…

Every centroaffine Tchebychev hyperovaloid is ellipsoid

Xiuxiu Cheng, Zejun Hu, Luc Vrancken

We study locally strongly convex Tchebychev hypersurfaces, namely the centroaffine totally umbilical hypersurfaces, in the (n+1)-dimensional affine space Rn+1. We first make an ordinary-looking observation that such hypersurfaces are characterized by having a Riemannian structure admitting a…

On a class of recursive estimators for spatially dependent observations

Mohamed El Machkouri, Lucas Reding

We investigate the mean squared error and the asymptotic normality for a class of recursive kernel estimators based on a sample of spatially dependent observations. Our main result provides sufficient conditions for a spatial version of a recursive estimator introduced by Hall and Patil (1994) to…

Adaptation in a heterogeneous environment. I: Persistence versus extinction

François Hamel, Florian Lavigne, Lionel Roques

Understanding how a diversity of plants in agroecosystems affects the adaptation of pathogens is a key issue in agroecology. We analyze PDE systems describing the dynamics of adaptation of two phenotypically structured populations, under the effects of mutation, selection and migration in a two-…
