Optimal non-reversible linear drift for the convergence to equilibrium of a diffusion
Tony Lelièvre, Francis Nier, Grigorios A. Pavliotis
We consider non-reversible perturbations of reversible diffusions that do not alter the invariant distribution and we ask whether there exists an optimal perturbation such that the…
Optimal scaling for the transient phase of Metropolis Hastings algorithms: The longtime behavior
Benjamin Jourdain, Tony Lelièvre, Błażej Miasojedow
We consider the Random Walk Metropolis algorithm on with Gaussian proposals, and when the target probability measure is the -fold product of a one-dimensional law…
A note on column subset selection
Pierre Youssef
Given a matrix U, using a deterministic method, we extract a "large" submatrix of U'(whose columns are obtained by normalizing those of U) and estimate its smallest and largest sin…
Analysis of Compatible Discrete Operator Schemes for Elliptic Problems on Polyhedral Meshes
Jerome Bonelle, Alexandre Ern
Compatible schemes localize degrees of freedom according to the physical nature of the underlying fields and operate a clear distinction between topological laws and closure relati…
On a variant of random homogenization theory: convergence of the residual process and approximation of the homogenized coefficients
Frederic Legoll, Florian Thomines
We consider the variant of stochastic homogenization theory introduced in [X. Blanc, C. Le Bris and P.-L. Lions, C. R. Acad. Sci. Serie I 2006 and Journal de Mathematiques Pures et…
Propagation of chaos for rank-based interacting diffusions and long time behaviour of a scalar quasilinear parabolic equation
Benjamin Jourdain, Julien Reygner
We study a quasilinear parabolic Cauchy problem with a cumulative distribution function on the real line as an initial condition. We call 'probabilistic solution' a weak solution w…
Properly embedded minimal annuli in
L. Hauswirth, M. Kilian, M. U. Schmidt
In there is a two-parameter family of properly embedded minimal annuli foliated by circles. In this paper we show that this family contains all pro…
Epigraphical splitting for solving constrained convex formulations of inverse problems with proximal tools
Giovanni Chierchia, Nelly Pustelnik, Jean-Christophe Pesquet +1
We propose a proximal approach to deal with a class of convex variational problems involving nonlinear constraints. A large family of constraints, proven to be effective in the sol…
Global existence for the critical dissipative surface quasi-geostrophic equation
Omar Lazar
In this article, we study the critical dissipative surface quasi-geostrophic equation (SQG) in . Motivated by the study of the homogeneous statistical solutions of t…
Rheology of sedimenting particle pastes
Abdoulaye Fall, Henri de Cagny, Daniel Bonn +4
We study the local and global rheology of non-Brownian suspensions in a solvent that is not density-matched, leading to either creaming or sedimentation of the particles. Both loca…
Role of electronic localization in the phosphorescence of iridium sensitizing dyes
Burak Himmetoglu, Alex Marchenko, Ismaila Dabo +1
In this work we present a systematic study of three representative iridium dyes, namely, Ir(ppy)3, FIrpic and PQIr, which are commonly used as sensitizers in organic optoelectronic…
Pathwise optimal transport bounds between a one-dimensional diffusion and its Euler scheme
A. Alfonsi, B. Jourdain, A. Kohatsu-Higa
In the present paper, we prove that the Wasserstein distance on the space of continuous sample-paths equipped with the supremum norm between the laws of a uniformly elliptic one-di…
Lagrangian flows for vector fields with gradient given by a singular integral
François Bouchut, Gianluca Crippa
We prove quantitative estimates on flows of ordinary differential equations with vector field with gradient given by a singular integral of an function. Such estimates allow…
A Note on Efficient Computation of All Abelian Periods in a String
Maxime Crochemore, Costas Iliopoulos, Tomasz Kociumaka +6
We derive a simple efficient algorithm for Abelian periods knowing all Abelian squares in a string. An efficient algorithm for the latter problem was given by Cummings and Smyth in…
Ultrafast spherulitic crystal growth as a stress-induced phenomenon specific of fragile glass-formers
Christiane Caroli, Anaël Lemaître
We propose a model for the abrupt emergence, below temperatures close to the glass transition, of the ultra-fast (GC) steady mode of spherulitic crystal growth in deeply undercoole…
Resilience of gas-phase anharmonicity in the vibrational response of adsorbed carbon monoxide and breakdown under electrical conditions
Ismaila Dabo
In surface catalysis, the adsorption of carbon monoxide on transition-metal electrodes represents the prototype of strong chemisorption. Notwithstanding significant changes in the…
A comparative study of crumpling and folding of thin sheets
Stephanie Deboeuf, Eytan Katzav, Arezki Boudaoud +2
Crumpling and folding of paper are at rst sight very di erent ways of con ning thin sheets in a small volume: the former one is random and stochastic whereas the latest one is regu…
The uniqueness property for networks with several origin-destination pairs
Frédéric Meunier, Thomas Pradeau
We consider congestion games on networks with nonatomic users and user-specific costs. We are interested in the uniqueness property defined by Milchtaich [Milchtaich, I. 2005. Topo…
A short proof of Paouris' inequality
Radosław Adamczak, Rafał Latała, Alexander E. Litvak +3
We give a short proof of a result of G. Paouris on the tail behaviour of the Euclidean norm of an isotropic log-concave random vector , stating that for every $t\ge…
Inelastic Mg+H collision data for non-LTE applications in stellar atmospheres
P. S. Barklem, A. K. Belyaev, A. Spielfiedel +2
Rate coefficients for inelastic Mg+H collisions are calculated for all transitions between the lowest seven levels and the ionic state (charge transfer). The rate coefficients are…
Scene Parsing with Multiscale Feature Learning, Purity Trees, and Optimal Covers
Clément Farabet, Camille Couprie, Laurent Najman +1
Scene parsing, or semantic segmentation, consists in labeling each pixel in an image with the category of the object it belongs to. It is a challenging task that involves the simul…
Concavification of free entropy
Philippe Biane, Yoann Dabrowski
We introduce a modification of Voiculescu's free entropy which coincides with the liminf variant of Voiculescu's free entropy on extremal states, but is a concave upper semi-contin…
