Efficiency of prompt quarantine measures on a susceptible-infected-removed model in networks
Takehisa Hasegawa, Koji Nemoto
This study focuses on investigating the manner in which a prompt quarantine measure suppresses epidemics in networks. A simple and ideal quarantine measure is considered in which a…
Sudden spreading of infections in an epidemic model with a finite seed fraction
Takehisa Hasegawa, Koji Nemoto
We study a simple case of the susceptible-weakened-infected-removed model in regular random graphs in a situation where an epidemic starts from a finite fraction of initially infec…
Local cluster-size statistics in the critical phase of bond percolation on the Cayley tree
Tomoaki Nogawa, Takehisa Hasegawa, Koji Nemoto
We study bond percolation of the Cayley tree (CT) by focusing on the probability distribution function (PDF) of a local variable, namely, the size of the cluster including a select…
Outbreaks in susceptible-infected-removed epidemics with multiple seeds
Takehisa Hasegawa, Koji Nemoto
We study a susceptible-infected-removed (SIR) model with multiple seeds on a regular random graph. Many researchers have studied the epidemic threshold of epidemic models above whi…
Critical Phase in Complex Networks: a Numerical Study
Takehisa Hasegawa, Tomoaki Nogawa, Koji Nemoto
We compare phase transition and critical phenomena of bond percolation on Euclidean lattices, nonamenable graphs, and complex networks. On a Euclidean lattice, percolation shows a…
Hierarchical scale-free network is fragile against random failure
Takehisa Hasegawa, Koji Nemoto
We investigate site percolation in a hierarchical scale-free network known as the Dorogovtsev- Goltsev-Mendes network. We use the generating function method to show that the percol…
