Auxetic two-dimensional lattice with Poisson's Ratio arbitrarily close to -1

open access: yes, 2014
In this paper we propose a new lattice structure having macroscopic Poisson's ratio arbitrarily close to the stability limit -1. We tested experimentally the effective Poisson's ratio of the micro-structured medium; the uniaxial test has been performed ...

Calibration and discrimination ability of the Dat'AIDS score in people living with HIV aged 70 years and older from the Dat'AIDS cohort

open access: yesHIV Medicine, EarlyView.
Abstract Objective The Dat'AIDS score was developed to predict 5‐year mortality risk in people living with HIV aged 60 and older. However, its validity in people living with HIV aged 70 years and older needed confirmation. Methods This was a multicentre prospective cohort study in the Dat'AIDS French cohort.

Posterior propriety in Bayesian extreme value analyses using reference priors [PDF]

open access: yes, 2015
The Generalized Pareto (GP) and Generalized extreme value (GEV) distributions play an important role in extreme value analyses, as models for threshold excesses and block maxima respectively. For each of these distributions we consider Bayesian inference
