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).

A lower bound for $p_c$ in range-$R$ bond percolation in two and three dimensions [PDF]
arXiv, 2016 We use the connection between bond percolation and SIR epidemics to establish lower bounds for the critical percolation probability in $2$ and $3$ dimensions as the range becomes large. The bound agrees with the conjectured asymptotics for the long range critical probability, refines results of M. Penrose, and complements results of van der Hofstad and

A Note on the Extinction of a Stochastic Differential Equation SIS Epidemic Model [PDF]
arXiv, 2019 The aim of this note is to give a new proof to the conjecture, proposed by Gray et al. (2011), on the extinction of a stochastic differential equation SIS epidemic model. The conjecture was proved by Xu (2017). Our proof is much more direct and simpler.

A primer on stochastic epidemic models: Formulation, numerical simulation, and analysis
Infectious Disease Modelling, 2017 Some mathematical methods for formulation and numerical simulation of stochastic epidemic models are presented. Specifically, models are formulated for continuous-time Markov chains and stochastic differential equations. Some well-known examples are used

Determination in Galicia of the required beds at Intensive Care Units
Alexandria Engineering Journal, 2021 By using a recent mathematical compartmental model that includes the super-spreader class and developed by Ndaïrou, Area, Nieto, and Torres, a procedure to estimate in advance the number of required beds at intensive care units is presented.

Curtailing the spread of drug-abuse and violence co-menace: An optimal control approach
Alexandria Engineering Journal, 2022 This work presents an optimal control of intervention strategies for a drug abuse and violence co-menace model considering a mass campaign against drug abuse, a mass campaign against violence, effective policing and rehabilitation of drug-abusing and ...
