We continue the study of renewal contact processes initiated in a companion paper, where we showed that if the tail of the interarrival distribution $\mu$ is heavier than $t^{-\alpha}$ for some $\alpha 1$, then the critical value is positive in the o

Considering tangential contact compliance, material nonlinearity and contact nonlinearity, an efficient multi-timescale computational approach (MCA) is presented to analyse the contact forces and transient wave propagation generated by the frictional

Schloegl's second model (also known as the quadratic contact process) on a lattice involves spontaneous particle annihilation at rate $p$ and autocatalytic particle creation at empty sites with $n\ensuremath{\ge}2$ occupied neighbors. The particle cr

We consider critical oriented Bernoulli percolation on the square lattice $$\mathbb {Z}^2$$ . We prove a Russo–Seymour–Welsh type result which allows us to derive several new results concerning the critical behavior: The sub-linear polynomial flu

Propagation of contagion in networks depends on the graph topology. This article is concerned with studying the time-asymptotic behaviour of the extended contact processes on static, undirected, finite-size networks. This is a contact process with no

In this article, we consider an anisotropic finite-range bond percolation model on $\mathbb {Z}^2$. On each horizontal layer $\{ (x,i)\colon x \in \mathbb {Z}\}$ we have edges $\langle (x,i),(y,i)\rangle $ for $1 \le |x-y|\le N$. There are also verti

We consider a contact process on $Z^d$ with two species that interact in a symbiotic manner. Each site can either be vacant or occupied by individuals of species $A$ and/or $B$. Multiple occupancy by the same species at a single site is prohibited. T

We investigate a non-Markovian analogue of the Harris contact process in a finite connected graph G=(V,E): an individual is attached to each site x in V, and it can be infected or healthy; the infection propagates to healthy neighbors just as in the

We show that the quasi-stationary distribution of the subcritical contact process on $\mathbb{Z}^d$ is unique. This is in contrast with other processes which also do not come down from infinity, like stable queues and Galton-Watson, and it seems to b

International audience; The Fredrickson-Andersen one spin facilitated model (FA-1f) on Z belongs to the class of kinetically constrained spin models (KCM). Each site refreshes with rate one its occupation variable to empty (respectively occupied) wit
