Fibrosis is a hallmark of human white adipose tissue (WAT) during obesity-induced chronic inflammation. The functional impact of increased interstitial fibrosis (peri-adipocyte fibrosis) on adjacentâ€¦ (More)

We consider a model of random walk in Z with (fixed or random) orientation of the horizontal lines (layers) and with non constant iid probability to stay on these lines. We prove the transience ofâ€¦ (More)

We study a branching system of random walks in random environment. Particles reproduce with a fixed reproduction law, and move as one-dimensional random walks in a common random environment. Ourâ€¦ (More)

We are interested in Sinaiâ€™s walk (Sn)nâˆˆN. We prove that the annealed probability that âˆ‘n k=0 f(Sk) is strictly positive for all n âˆˆ [1, N ] is equal to 1/(logN) 3âˆ’ âˆš 5 2 , for a large class ofâ€¦ (More)

We consider a one-dimensional diffusion process in a drifted Brownian potential. We are interested in the maximum of its local time, and study its almost sure asymptotic behaviour, which is proved toâ€¦ (More)

In this paper, we are interested in some questions of Greven and den Hollander [3] about the rate function I Î· of quenched large deviations for random walk in random environment. By studying theâ€¦ (More)

We study persistence probabilities for random walks in correlated Gaussian random environment first studied by Oshanin, Rosso and Schehr [27]. From the persistence results, we can deduce propertiesâ€¦ (More)
