Branching processes in correlated random environment
Electronic Communications in Probability, 2019 We consider the critical branching processes in correlated random environment which is positively associated and study the probability of survival up to the n-th generation. Moreover, when the environment is given by fractional Brownian motion, we estimate also the tail of progeny as well as the tail of width.

Journal of Imaging, 2023 Radiomic analysis allows for the detection of imaging biomarkers supporting decision-making processes in clinical environments, from diagnosis to prognosis. Frequently, the original set of radiomic features is augmented by considering high-level features,

Extended Void Merging Tree Algorithm for Self-Similar Models [PDF]
, 2013 In hierarchical evolution, voids exhibit two different behaviors related with their surroundings and environments, they can merge or collapse. These two different types of void processes can be described by the two-barrier excursion set formalism based ...

Multivariate analysis of functional metagenomes
Frontiers in Genetics, 2013 Metagenomics is a primary tool for the description of microbial and viral communities. The sheer magnitude of the data generated in each metagenome makes identifying key differences in the function and taxonomy between communities difficult to elucidate.

The stability of conditional Markov processes and Markov chains in random environments
, 2009 We consider a discrete time hidden Markov model where the signal is a stationary Markov chain. When conditioned on the observations, the signal is a Markov chain in a random environment under the conditional measure.

Comparative study of the critical behavior in one-dimensional random and aperiodic environments
, 1998 We consider cooperative processes (quantum spin chains and random walks) in one-dimensional fluctuating random and aperiodic environments characterized by fluctuating exponents omega>0.

Stochastic characterization of navigation strategies in an automated variant of the Barnes maze
eLifeAnimals can use a repertoire of strategies to navigate in an environment, and it remains an intriguing question how these strategies are selected based on the nature and familiarity of environments.

Jump-diffusion processes in random environments
Journal of Differential Equations, 2014 In this paper we investigate jump-diffusion processes in random environments which are given as the weak solutions to SDE's. We formulate conditions ensuring existence and uniqueness in law of solutions. We investigate Markov property. To prove uniqueness we solve a general martingale problem for \cadlag processes.
