Cancellous bone and theropod dinosaur locomotion. Part I-an examination of cancellous bone architecture in the hindlimb bones of theropods. [PDF]
PeerJ, 2018 This paper is the first of a three-part series that investigates the architecture of cancellous (‘spongy’) bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous bone architectural patterns to infer locomotor biomechanics in extinct ...

A Semi-Lagrangian scheme for a modified version of the Hughes model for pedestrian flow [PDF]
, 2016 In this paper we present a Semi-Lagrangian scheme for a regularized version of the Hughes model for pedestrian flow. Hughes originally proposed a coupled nonlinear PDE system describing the evolution of a large pedestrian group trying to exit a domain as

Propagation of chaos and Poincar\'e inequalities for a system of particles interacting through their cdf [PDF]
, 2008 In the particular case of a concave flux function, we are interested in the long time behaviour of the nonlinear process associated to the one-dimensional viscous scalar conservation law.

Long-time convergence of an adaptive biasing force method: Variance reduction by Helmholtz projection [PDF]
, 2015 In this paper, we propose an improvement of the adaptive biasing force (ABF) method, by projecting the estimated mean force onto a gradient. The associated stochastic process satisfies a non linear stochastic differential equation.

A formal view on 2.5 large deviations and fluctuation relations
, 2015 We obtain the rate function for the level 2.5 of large deviations for pure jump and diffusion processes. This result is proved by two methods: tilting, for which a tilted process with an appropriate typical behavior is considered, and a spectral method ...

On the spectral analysis of second-order Markov chains [PDF]
, 2012 36 pagesInternational audienceSecond order Markov chains which are trajectorially reversible are considered. Contrary to the reversibility notion for usual Markov chains, no symmetry property can be deduced for the corresponding transition operators ...
