Noninvasive characterization of oocyte deformability in microconstrictions

Lucie Barbier, Rose Bulteau, Behnam Rezaei, Thomas Panier, Gaëlle Letort, Elsa Labrune, Marie-Hélène Verlhac, Franck Vernerey, Clément Campillo, Marie-Emilie Terret

Oocytes naturally present mechanical defects that hinder their development after fertilization. Thus, in the context of assisted reproduction, oocyte selection based on their mechanical properties has great potential to improve the quality of the resulting embryos and the success rate of these…

Geometric theory of (extended) time-reversal symmetries in stochastic processes: I. Finite dimension

J O’byrne, M E Cates

Abstract In this article, we analyze three classes of time-reversal of a Markov process with Gaussian noise on a manifold. We first unveil a commutativity constraint for the most general of these time-reversals to be well defined. Then we give a triad of necessary and sufficient conditions for the…

Bridging Wright-Fisher and Moran models

Arthur Alexandre, Alia Abbara, Cecilia Fruet, Claude Loverdo, Anne-Florence Bitbol

The Wright-Fisher model and the Moran model are both widely used in population genetics. They describe the time evolution of the frequency of an allele in a well-mixed population with fixed size. We propose a simple and tractable model which bridges the Wright-Fisher and the Moran descriptions. We…
