Stochastic Epigenetic Mutations Influence Parkinson’s Disease Risk, Progression, and Mortality
Journal of Parkinson’s Disease, 2022 Background: Stochastic epigenetic mutations (SEM) reflect a deviation from normal site-specific methylation patterns. Epigenetic mutation load (EML) captures the accumulation of SEMs across an individual’s genome and may reflect dysfunction of the ...

Dynamic Behavior of an Interactive Mosquito Model under Stochastic Interference
Mathematics, 2022 For decades, mosquito-borne diseases such as dengue fever and Zika have posed serious threats to human health. Diverse mosquito vector control strategies with different advantages have been proposed by the researchers to solve the problem.

Variance and Interest Rate Risk in Unit-Linked Insurance Policies
Risks, 2020 One of the risks derived from selling long-term policies that any insurance company has arises from interest rates. In this paper, we consider a general class of stochastic volatility models written in forward variance form.

Risks, 2022 We construct a new age-specific mortality framework and implement an exemplar (DLGC) that provides an excellent fit to data from various countries and across long time periods while also providing accurate mortality forecasts by projecting parameters ...

Stochastic Mortality, Macroeconomic Risks, and Life Insurer Solvency [PDF]
SSRN Electronic Journal, 2009 Motivated by a recent demographic study establishing a link between macroeconomic fluctuations and the mortality index k t in the lee–carter model, we develop a dynamic asset-liability model to assess the impact of macroeconomic fluctuations on the solvency of a life insurance company. Liabilities in this stochastic simulation framework are driven by a

Mortality Projections for Small Populations: An Application to the Maltese Elderly
Risks, 2019 In small populations, mortality rates are characterized by a great volatility, the datasets are often available for a few years and suffer from missing data.

Journal of Mathematics, 2022 In view of a time lag between the time that the prey perceive predator signals and make some changes or behavior responses, we establish a predator–prey system with direct and indirect predation in this paper.

Stability of positive equilibrium of a Nicholson blowflies model with stochastic perturbations
Electronic Journal of Qualitative Theory of Differential Equations, 2020 This paper is concerned with the stability problem of the positive equilibrium of a Nicholson's blowflies model with nonlinear density-dependent mortality rate subject to stochastic perturbations.
