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…

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…

Discontinuous Transition of a Multistage Independent Cascade Model on Networks

Takehisa Hasegawa, Koji Nemoto

We propose a multistage version of the independent cascade model, which we call a multistage independent cascade (MIC) model, on networks. This model is parameterized by two probab…

Robustness of correlated networks against propagating attacks

Takehisa Hasegawa, Keita Konno, Koji Nemoto

We investigate robustness of correlated networks against propagating attacks modeled by a susceptible-infected-removed model. By Monte-Carlo simulations, we numerically determine t…
