Threshold dynamics of a stochastic mathematical model for Wolbachia infections

open access: yesJournal of Biological Dynamics, 2023
A stochastic mathematical model is proposed to study how environmental heterogeneity and the augmentation of mosquitoes with [Formula: see text] bacteria affect the outcomes of dengue disease. The existence and uniqueness of the positive solutions of the

Ergodic BSDEs and Optimal Ergodic Control in Banach Spaces [PDF]

open access: yesSIAM Journal on Control and Optimization, 2009
In this paper we introduce a new kind of Backward Stochastic Differential Equations, called ergodic BSDEs, which arise naturally in the study of optimal ergodic control. We study the existence, uniqueness and regularity of solution to ergodic BSDEs. Then we apply these results to the optimal ergodic control of a Banach valued stochastic state equation.

Ergodic Subspace Analysis [PDF]

open access: yesJournal of Intelligence, 2020
Properties of psychological variables at the mean or variance level can differ between persons and within persons across multiple time points. For example, cross-sectional findings between persons of different ages do not necessarily reflect the development of a single person over time.

Wavelet Estimation of Partial Derivatives in Multivariate Regression Under Discrete-Time Stationary Ergodic Processes

open access: yesMathematics
This study introduces a wavelet-based framework for estimating derivatives of a general regression function within discrete-time, stationary ergodic processes. The analysis focuses on deriving the integrated mean squared error (IMSE) over compact subsets

Coexistence for a kind of stochastic three-species competitive models

open access: yesOpen Mathematics, 2019
The coexistence of species sustains the ecological balance in nature. This paper focuses on sufficient conditions for the coexistence of a three-species stochastic competitive model, where the model has non-linear diffusion parts.

Ergodicity-Breaking in Thermal Biological Electron Transfer? Cytochrome C Revisited

open access: yes, 2019
It was recently suggested that certain redox proteins operate in an ergodicity-breaking regime to facilitate biological electron transfer (ET).

Coefficients of ergodicity generated by non-symmetrical vector norms [PDF]

open access: yes, 1988
Explicit forms for ergodicity coefficients are known in the cases when the l1-norm or the l∞-norm are used [1], [2]. The purpose of this paper is the calculation of the maximal value of the ergodicity coefficient for an arbitrary vector norm. Connections

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

open access: yesAdvanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...
