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…

Sintering of Ceramics: An Overview

Anne Leriche, Francis Cambier, Stuart Hampshire

This article gives an overview of surface and bulk matter transport processes occurring during the densification of ceramic powder compacts. Starting from purified or chemically synthesized raw materials, sintering takes place by either solid state or liquid phase mechanisms during heat treatment…

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-…

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…

Facile synthesis of fluorine-free, hydrophobic, and highly transparent coatings for self-cleaning applications

Abderrahmane Hamdi, Julie Chalon, Pascal Laurent, Benoit Dodin, El Hadj Dogheche, Philippe Champagne

Non-fluorinated coatings have recently emerged as a new approach to avoid contamination on transparent surfaces. This research work concerns the synthesis of highly transparent, hydrophobic, durable, and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The…

The 2d-directed spanning forest converges to the Brownian web

David Coupier, Kumarjit Saha, Anish Sarkar, Viet Chi Tran

The two-dimensional directed spanning forest (DSF) introduced by Baccelli and Bordenave is a planar directed forest whose vertex set is given by a homogeneous Poisson point process $\mathcal{N}$ on $\mathbb{R}^2$. If the DSF has direction $-e_y$, the ancestor $h(u)$ of a vertex $u \in \mathcal{N}$…
