Universal tradeoff relation between speed, uncertainty, and dissipation in nonequilibrium stationary states

SciPost Physics, 2022
We derive universal thermodynamic inequalities that bound from below the moments of first-passage times of stochastic currents in nonequilibrium stationary states of Markov jump processes in the limit where the thresholds that define the first ...

On the simulation technique of stochastic processes and nonlinear vibrations

Vietnam Journal of Mechanics, 1994
In this paper the procedure and program for simulation of stochastic processes are represented. The program is applied to nonlinear mechanical systems subjected to stochastic stationary excitation.

Stochastic metrology and the empirical distribution

Physical Review Research, 2023
We study the problem of parameter estimation in time series stemming from general stochastic processes, where the outcomes may exhibit arbitrary temporal correlations.

On nonnegative solutions of SDDEs with an application to CARMA processes

Modern Stochastics: Theory and Applications, 2021
This note provides a simple sufficient condition ensuring that solutions of stochastic delay differential equations (SDDEs) driven by subordinators are nonnegative.

Generalized speed limits for classical stochastic systems and their applications to relaxation, annealing, and pumping processes

Physical Review Research, 2023
We extend the speed limit of a distance between two states evolving by different generators for quantum systems [K. Suzuki and K. Takahashi, Phys. Rev. Res.

Permutation Complexity and Coupling Measures in Hidden Markov Models

Entropy, 2013
Recently, the duality between values (words) and orderings (permutations) has been proposed by the authors as a basis to discuss the relationship between information theoretic measures for finite-alphabet stationary stochastic processes and their ...

Summing Modulo 2 of Stationary Binary Stochastic Processes

IEEE Access
In the paper, we analyze the properties of the stochastic process obtained as the result of summing modulo 2 without carry of a finite number of stationary binary stochastic processes, some of which do not satisfy the independence condition.

Universal Kriging Prediction of nonstationary Spatial Stochastic Process [PDF]

المجلة العراقية للعلوم الاحصائية, 2010
Spatial Stochastic processes are often divided into two types that are stationary spatial stochastic processes and other nonstationary. In most practical applications the processes are nonstationary .Prediction of these processes are performed by ...

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,
