A sharp threshold for a modified bootstrap percolation with recovery [PDF]
Journal of Statistical Physics, Volume 157, Issue 3 (2014), pp
531-570, 2015 Bootstrap percolation is a type of cellular automaton on graphs, introduced as a simple model of the dynamics of ferromagnetism. Vertices in a graph can be in one of two states: `healthy' or `infected' and from an initial configuration of states, healthy vertices become infected by local rules.

An age-of-infection model with both symptomatic and asymptomatic infections [PDF]
arXiv, 2021 We formulate a general age-of-infection epidemic model with two pathways: the symptomatic infections and the asymptomatic infections. We then calculate the basic reproduction number $\mathcal{R}_0$ and establish the final size relation. It is shown that the ratio of accumulated counts of symptomatic patients and asymptomatic patients is determined by ...
