High-Risk Immunization Strategies for Multiethnic Regions

Figure 4

The computer simulations of SIRS model with high-risk immunization on BA scale-free networks (𝑁=2000, ⟨𝑘⟩=6). (a) The changing of infected density 𝐼(𝜆) as a function of 𝜆, with 𝛿=0.3, 𝛿=0.5, and 𝛿=0.7. 𝜁_𝐴𝐵=𝜁_𝐵𝐶=𝜁_𝐴𝐶=0.7. (b) The changing of infected density 𝐼(𝜆) as a function of 𝜆, with 𝜁=0.2, 𝜁=0.4, 𝜁=0.6, 𝜁=0.8, and 𝜁=1 (𝜁_𝐴𝐵=𝜁_𝐵𝐶=𝜁_𝐴𝐶=𝜁). 𝛿=0.3.
