A Simple Model of Epidemics with Pathogen Mutation
Michelle Girvan, Duncan S. Callaway, M. E. J. Newman +1
We study how the interplay between the memory immune response and pathogen mutation affects epidemic dynamics in two related models. The first explicitly models pathogen mutation a…
Are randomly grown graphs really random?
Duncan S. Callaway, John E. Hopcroft, Jon M. Kleinberg +2
We analyze a minimal model of a growing network. At each time step, a new vertex is added; then, with probability delta, two vertices are chosen uniformly at random and joined by a…
Network robustness and fragility: Percolation on random graphs
D. S. Callaway, M. E. J. Newman, S. H. Strogatz +1
Recent work on the internet, social networks, and the power grid has addressed the resilience of these networks to either random or targeted deletion of network nodes. Such deletio…
