Optimal control of multiple Markov-switching stochastic systems with numerical applications

open access: yesResults in Control and Optimization, 2022
In this article the authors set up an optimal control framework for a hybrid stochastic system with dual or multiple Markov switching diffusion processes, while Markov chains governing these switching diffusions are not identical as assumed in the ...

Over two decades of research on the marine RNA virosphere

open access: yesiMeta, Volume 1, Issue 4, December 2022., 2022
Advances in meta‐omics provide a surge of marine RNA virus information. Deep marine virus discovery contributes greatly to the megataxonomy of RNA viruses. Understanding diversity and biogeography helps reveal the significance of marine RNA viruses, including evolutionary trajectories, hierarchical taxonomy, and ecological importance.

Analyzing the profit-loss sharing contracts with Markov model

open access: yesCommunications in Science and Technology, 2016
The purpose of this paper is to examine how to use first order Markov chain to build a reliable monitoring system for the profit-loss sharing based contracts (PLS) as the mode of financing contracts in Islamic bank with censored continuous-time ...

Fully Coupled Forward-backward Stochastic Differential Equations on Markov Chains [PDF]

open access: yesarXiv, 2015
We define fully coupled forward-backward stochastic differential equations on spaces related to continuous time, finite state Markov Chains. Existence and uniqueness results of the fully coupled forward-backward stochastic differential equations on Markov Chains are obtained.

Regional Shopping Objectives in British Grocery Retail Transactions Using Segmented Topic Models

open access: yesApplied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Understanding the customer behaviours behind transactional data has high commercial value in the grocery retail industry. Customers generate millions of transactions every day, choosing and buying products to satisfy specific shopping needs.

A Markov – Chain Model for the Tuberculosis in Salah Aldeen City (1991-1999) [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2006
This paper studies a time series for the number of infection of Tuberculosis of the lungs as a Markov – chain. We have made hypotheses concerning the number of infections in order to set the problem according to Markov-chain.

Model Bias Identification for Bayesian Calibration of Stochastic Digital Twins of Bridges

open access: yesApplied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Simulation‐based digital twins must provide accurate, robust, and reliable digital representations of their physical counterparts. Therefore, quantifying the uncertainty in their predictions plays a key role in making better‐informed decisions that impact the actual system.

Bayesian estimation of multivariate panel probits with higher‐order network interdependence and an application to firms' global market participation in Guangdong

open access: yesJournal of Applied Econometrics, Volume 37, Issue 7, Page 1356-1378, November/December 2022., 2022
Summary This paper proposes a Bayesian estimation framework for panel data sets with binary dependent variables where a large number of cross‐sectional units are observed over a short period of time and cross‐sectional units are interdependent in more than a single network domain.
