Table 3 Variables defining the metapopulation model with one class of individuals in the degree-block approximation
From: Age-specific contacts and travel patterns in the spatial spread of 2009 H1N1 influenza pandemic
Variable | Definition |
|---|---|
k | Degree of a subpopulation, i.e. number of airline connections to other subpopulations |
V, V k | Total number of subpopulations, number of subpopulations with degree k |
N k | Population size of subpopulations with degree k |
w kk ' = w 0(kk ')θ | Number of passengers flying from a subpopulation with degree k to a subpopulation with degree k’ |
w 0 | Mobility scale |
d kk ' = w kk '/N k | Diffusion rate of passengers flying from a subpopulation with degree to a subpopulation with degree k’ |
