Extinction time for a random walk in a random environment [PDF]
, 2015 We consider a random walk with death in [-N, N] moving in a time dependent environment. The environment is a system of particles which describes a current ?ux from N to -N.

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Random walks in a random environment
Proceedings Mathematical Sciences, 2004 Random walks as well as diffusions in random media are considered. Methods are developed that allow one to establish large deviation results for both the `quenched' and the `averaged' case.

RANDOM WALK IN QUASI-PERIODIC RANDOM ENVIRONMENT [PDF]
Stochastics and Dynamics, 2009 We consider a one-dimensional random walk with finite range in a random medium described by an ergodic translation on a torus. For regular data and under a Diophantine condition on the translation, we prove a central limit theorem with deterministic centering.

Branching processes in random environment
, 2011 In der folgenden Arbeit werden Eigenschaften von Verzweigungsprozessen in zufälliger Umgebung (engl. branching processes in random environment, kurz BPREs) untersucht. Das Modell geht auf Smith (1969) und Athreya (1971) zurück. Ein BPRE ist ein einfaches

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Large Deviations for a Random Walk in Random Environment
The Annals of Probability, 1994 Let \(\omega = (p_ x)_{x \in \mathbb{Z}}\) be a sequence of i.i.d. r.v.s taking values in (0,1). Given \(\omega\), let \((X_ n)_{n\geq 0}\) be a Markov chain with \(X_ 0 = 0\) and \(X_{n + 1} = X_ n + 1\) (resp. \(X_ n - 1\)) with probability \(p_{X_ n}\) (resp. \(1 - p_{X_ n}\)). It is shown that \(X_ n/n\) satisfies \[ \lim_{n \to \infty} {1\over n} \
