A Test of Association between Qualitative Trait and a Set of SNPs [PDF]
, 2007 2000 Mathematics Subject Classification: 62P10, 92D10, 92D30, 62F03In this article, we propose a novel candidate-gene association test that utilizes a set of tightly linked single nucleotide polymorphisms (SNPs).

A stochastic epidemic model of COVID-19 disease [PDF]
arXiv, 2020 To model the evolution of diseases with extended latency periods and the presence of asymptomatic patients like COVID-19, we define a simple discrete time stochastic SIR-type epidemic model. We include both latent periods as well as the presence of quarantine areas, to capture the evolutionary dynamics of such diseases.

Effect of awareness and saturated treatment on the transmission of infectious diseases
Computational and Mathematical BiophysicsIn this article, we study the role of awareness and its impact on the control of infectious diseases. We analyze a susceptible-infected-recovered model with a media awareness compartment. We find the effective reproduction number R0{R}_{0}.

SIR epidemics on a scale-free spatial nested modular network with a non-trivial threshold [PDF]
arXiv, 2011 We propose a class of random scale-free spatial networks with nested community structures and analyze Reed-Frost epidemics with community related independent transmissions. We show that the epidemic threshold may be trivial or not depending on the relation among community sizes, distribution of the number of communities and transmission ...

Mathematical modelling of COVID-19 dynamics using SVEAIQHR model
Computational and Mathematical BiophysicsIn this study, we formulate an eight-compartment mathematical model with vaccination as one of the compartments to analyze the dynamics of COVID-19 transmission.

Modeling Stochastic Anomalies in an SIS and SIRS System [PDF]
arXiv, 2012 I propose a stochastic SIS and SIRS system to include a Poisson measure term to model anomalies in the dynamics. In particular the positive integrand in the Poisson term is intended to model quarantine. Conditions are given for the stability of the disease free equilibrium for both systems.

On the error of incidence estimation from prevalence data [PDF]
arXiv, 2014 This paper describes types of errors arising in a recently proposed method of incidence estimation from prevalence data. The errors are illustrated by a simulation study about a hypothetical irreversible disease. In addition, a way of obtaining error bounds in practical applications of the method is proposed.

State model for partly undetected non-communicable diseases (NCDs) [PDF]
arXiv, 2014 This article proposes an age-structured compartment model for irreversible diseases with a pre-clinical state of undiagnosed cases that precedes the diagnosis. The model is able to cope with mortality rates differing between the pre-clinical and the clinical state (differential mortality).
