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...

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...

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-...

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...

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 $u \in \mathcal{N}$...

Linear hyperbolic systems on networks: well-posedness and qualitative properties

Marjeta Kramar Fijavž, Delio Mugnolo, Serge Nicaise

We study hyperbolic systems of one-dimensional partial differential equations under general, possibly non-local boundary conditions. A large class of evolution equations, either on individual 1-dimensional intervals or on general networks, can be reformulated in our rather flexible formalism, which...

Affine hypersurfaces with constant sectional curvature

Miroslava Antić, Haizhong Li, Luc Vrancken, Xianfeng Wang

We use a new approach to study locally strongly convex hypersurfaces with constant sectional curvature in the affine space (Formula presented). We prove a nice relation involving the eigenvalues of the shape operator S and the difference tensor K of the affine hypersurface. This is achieved by...

Piezoelectric and Electromechanical Characteristics of Porous Poly(Ethylene-co-Vinyl Acetate) Copolymer Films for Smart Sensors and Mechanical Energy Harvesting Applications

Chouaib Ennawaoui, Abdelowahed Hajjaji, Cédric Samuel, Erroumayssae Sabani, Abdelkader Rjafallah, Ikrame Najihi, El Mehdi Laadissi, El Mehdi Loualid, Mohamed Rguiti, Abdessamad El Ballouti, Azeddine Azim

This paper investigates energy harvesting performances of porous piezoelectric polymer films to collect electrical energy from vibrations and power various sensors. The influence of void content on the elastic matrix, dielectric, electrical, and mechanical properties of porous piezoelectric polymer...
