Fisher information of correlated stochastic processes

open access: yesNew Journal of Physics, 2023
Many real-world tasks include some kind of parameter estimation, i.e. the determination of a parameter encoded in a probability distribution. Often, such probability distributions arise from stochastic processes.

Performing Parallel Monte Carlo and Moment Equations Methods for Itô and Stratonovich Stochastic Differential Systems: R Package Sim.DiffProc

open access: yesJournal of Statistical Software, 2020
We introduce Sim.DiffProc, an R package for symbolic and numerical computations on scalar and multivariate systems of stochastic differential equations (SDEs). It provides users with a wide range of tools to simulate, estimate, analyze, and visualize the

Entropy Production in Stochastics

open access: yesEntropy, 2017
While the modern definition of entropy is genuinely probabilistic, in entropy production the classical thermodynamic definition, as in heat transfer, is typically used.

The neuronal response at extended timescales: a linearized spiking input-output relation

open access: yesFrontiers in Computational Neuroscience, 2014
Many biological systems are modulated by unknown slow processes. This can severely hinder analysis - especially in excitable neurons, which are highly non-linear and stochastic systems.

A review of entropy measures for uncertainty quantification of stochastic processes

open access: yesAdvances in Mechanical Engineering, 2019
Entropy is originally introduced to explain the inclination of intensity of heat, pressure, and density to gradually disappear over time. Based on the concept of entropy, the Second Law of Thermodynamics, which states that the entropy of an isolated ...

Approximate reduction of linear population models governed by stochastic differential equations: application to multiregional models

open access: yesJournal of Biological Dynamics, 2017
In this work we develop approximate aggregation techniques in the context of slow-fast linear population models governed by stochastic differential equations and apply the results to the treatment of populations with spatial heterogeneity.

Stochastic Acceleration in Weakly Turbulent Astrophysical Environments

open access: yesThe Astrophysical Journal
Turbulent magnetic fields are to some extent a universal feature in astrophysical phenomena. Charged particles that encounter this turbulence are typically accelerated according to the so-called second-order Fermi process.
