Harvesting Reshapes Dynamical Populations
R. K. Singh, Michael Assaf, Jason R. Green +1
Harvesting -- the periodic removal of individuals above or below a threshold trait value -- reshapes heterogeneous populations without altering their underlying stochastic dynamics…
Non-Markovian gene expression
Ohad Vilk, Ralf Metzler, Michael Assaf
We study two non-Markovian gene-expression models in which protein production is a stochastic process with a fat-tailed non-exponential waiting time distribution (WTD). For both mo…
Heterogeneity can markedly increase final outbreak size in the SIR model of epidemics
Alexander Leibenzon, Michael Assaf
We study the SIR model of epidemics on positively correlated heterogeneous networks with population variability, and explore the dependence of the final outbreak size on the networ…
SIS model of disease extinction on heterogeneous directed population networks
Elad Korngut, Jason Hindes, Michael Assaf
Understanding the spread of diseases through complex networks is of great interest where realistic, heterogeneous contact patterns play a crucial role in the spread. Most works hav…
Fluctuations and first-passage properties of systems of Brownian particles with reset
Ohad Vilk, Michael Assaf, Baruch Meerson
We study stationary fluctuations in two models involving Brownian particles undergoing stochastic resetting to the origin in 1d. We start with the basic reset model where the p…
Classification of anomalous diffusion in animal movement data using power spectral analysis
Ohad Vilk, Erez Aghion, Ran Nathan +3
The field of movement ecology has seen a rapid increase in high-resolution data in recent years, leading to the development of numerous statistical and numerical methods to analyse…
