Structured Modeling and Analysis of Stochastic Epidemics with Immigration and Demographic Effects. [PDF]

open access: yesPLoS ONE, 2016
Stochastic epidemics with open populations of variable population sizes are considered where due to immigration and demographic effects the epidemic does not eventually die out forever.

Dependability Analysis of Bitcoin subject to Eclipse Attacks [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2021
The immense potential of the blockchain technology in diverse and critical applications (e.g., financial services, cryptocurrencies, supply chains, smart contracts, and automotive industry) has led to a new challenge: the dependability modeling and ...

Maximum Entropy Estimation of Transition Probabilities of Reversible Markov Chains

open access: yesEntropy, 2009
In this paper, we develop a general theory for the estimation of the transition probabilities of reversible Markov chains using the maximum entropy principle. A broad range of physical models can be studied within this approach.

Methodology for the Assessment of Imprecise Multi-State System Availability

open access: yesMathematics, 2022
Most existing studies of a system’s availability in the presence of epistemic uncertainties assume that the system is binary. In this paper, a new methodology for the estimation of the availability of multi-state systems is developed, taking into ...

Stochastic metrology and the empirical distribution

open access: yesPhysical 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.

Understanding Our Markov Chain Significance Test: A Reply to Cho and Rubinstein-Salzedo

open access: yesStatistics and Public Policy, 2019
The article of Cho and Rubinstein-Salzedo seeks to cast doubt on our previous paper, which described a rigorous statistical test which can be applied to reversible Markov chains.

Dynamic event‐based dissipative asynchronous control for singular Markov jump LPV systems with general transition rates

open access: yesIET Control Theory & Applications, 2021
In this article, the dissipative asynchronous control is investigated for a series of continuous‐time singular Markov jump linear parameter‐varying (SMJLPV) systems under a dynamic event‐triggered scheme, in which the system parameters depend on the ...

Healthy longevity from incidence-based models: More kinds of health than stars in the sky

open access: yesDemographic Research, 2021
Background: Healthy longevity (HL) is an important measure of the prospects for quality of life in ageing societies. Incidence-based (cf. prevalence-based) models describe transitions among age classes and health stages.

A Stochastic Maximum Principle for Markov Chains of Mean-Field Type

open access: yesGames, 2018
We derive sufficient and necessary optimality conditions in terms of a stochastic maximum principle (SMP) for controls associated with cost functionals of mean-field type, under dynamics driven by a class of Markov chains of mean-field type which are ...

On the Construction of Some Deterministic and Stochastic Non-Local SIR Models

open access: yesMathematics, 2020
Fractional-order epidemic models have become widely studied in the literature. Here, we consider the generalization of a simple SIR model in the context of generalized fractional calculus and we study the main features of such model.
