Coupled Dynamic Model of Resource Diffusion and Epidemic Spreading in Time-Varying Multiplex Networks

Figure 7

The heat maps of as a function of a pair of and (a–c) and and (b–d). (a, b) and are approximately uncorrelated with the outbreak threshold and effectively affect the spread of disease, which suggests that the dynamic social relationships of individuals in the resource layer cannot inhibit the outbreak of the disease but can effectively suppress the spreading of disease. (c, d) and significantly affect the outbreak threshold and the spread of disease, which suggests that the dynamic physical contacts of individuals in the epidemic layer have strong influences on the dynamic process of epidemic spreading. The other fixed parameters are  = 0.10,  = 0.64,  = 0.48, and  = 5 for (a), (c), and (d);  = 5 for (a), (b), and (c);  = 2.5 for (b), (c), and (d); and  = 2.5 for (a), (b), and (d).
