Occupation time theorems for one-dimensional random walks and diffusion processes in random environments [PDF]
, 2009 The long time asymptotics of the time spent on the positive side are discussed for one-dimensional diffusion processes in random environments. The limiting distributions under the log–log scale are obtained for the diffusion processes in the stable ...

Branching processes in near-critical random environments [PDF]
, 2004 Branching processes are studied in random environments that are influenced by the population size and approach criticality as the population gets large.

IEEE AccessThis study explores the potential to predict turbulent kinetic energy (TKE) from more readily acquired temperature data using temperature profiles and turbulence data collected concurrently at 10 Hz during a small experimental prescribed burn in the New ...

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,

Branching processes in a random environment with immigration stopped at zero [PDF]
Journal of Applied Probability, 2020 AbstractA critical branching process with immigration which evolves in a random environment is considered. Assuming that immigration is not allowed when there are no individuals in the population, we investigate the tail distribution of the so-called life period of the process, i.e. the length of the time interval between the moment when the process is

Random walks in random environments without ellipticity [PDF]
, 2013 We consider random walks in random environments on Z^d. Under a transitivity hypothesis that is much weaker than the customary ellipticity condition, and assuming an absolutely continuous invariant measure on the space of the environments, we prove the ...

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.

On the Survival Probability of a Branching Process in a Random Environment
Advances in Applied Probability, 1997 We derive a variety of estimates for the survival probability of a branching process in a random environment. There are three cases of interest, the critical, weakly and strongly subcritical. The large deviation result, first obtained by Dekking for the class of finite state space i.i.d. environments, is shown to hold in more general environments.

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.
