Transition times and stochastic resonance for multidimensional diffusions with time periodic drift: A large deviations approach

, 2006
We consider potential type dynamical systems in finite dimensions with two meta-stable states. They are subject to two sources of perturbation: a slow external periodic perturbation of period $T$ and a small Gaussian random perturbation of intensity ...

Urbanization drives riverine bacterial antibiotic resistome more than taxonomic community at watershed scale

Environment International, 2020
Although the occurrence and distribution of antibiotic resistance genes (ARGs) in various aquatic ecosystems are well explored, understanding of the ecological processes and mechanisms governing the composition and dynamics of bacterial ARGs still ...

Cell shape analysis of random tessellations based on Minkowski tensors

, 2016
To which degree are shape indices of individual cells of a tessellation characteristic for the stochastic process that generates them? Within the context of stochastic geometry and the physics of disordered materials, this corresponds to the question of ...

Powers of the Stochastic Gompertz and Lognormal Diffusion Processes, Statistical Inference and Simulation

Mathematics, 2020
In this paper, we study a new family of Gompertz processes, defined by the power of the homogeneous Gompertz diffusion process, which we term the powers of the stochastic Gompertz diffusion process.

On Stochastic Equations with Measurable Coefficients Driven by Symmetric Stable Processes [PDF]

International Journal of Stochastic Analysis, 2012
We consider a one-dimensional stochastic equation , , with respect to a symmetric stable process of index . It is shown that solving this equation is equivalent to solving of a 2-dimensional stochastic equation with respect to the semimartingale and corresponding matrix .

Path integral for multiplicative noise: Generalized Fokker-Planck equation  and entropy production rate in stochastic processes with threshold

Physical Review Research
This paper introduces a comprehensive extension of the path-integral formalism to model stochastic processes with arbitrary multiplicative noise. To do so, the Itô diffusive process is generalized by incorporating a multiplicative noise term [η(t)] that ...

Reservoir ecological operation by quantifying outflow disturbance to aquatic community dynamics

Environmental Research Letters, 2021
Reservoir operation causes spatiotemporal variations in outflow, which influence the dynamics of downstream aquatic communities. However, empirical evidence of community responses to hydrological alteration remains limited for dam-regulated rivers.
