Characterization of extremal epidemic networks with diffusion characters
2008
2008 IEEE Symposium on Computational Intelligence in Bioinformatics and Computational Biology
Preserved Fulltext
These networks represent extremal cases of network behavior. ...
The diffusion character matrix analysis allows us to place several metric-like dissimilarity measure on the space of graphs with a fixed number of nodes. ...
Diffusion character based measures of the difference between pairs of networks are computed by first sorting the diffusion character matrices in some fashion. ...

We study the dynamics of epidemic and reaction-diffusion processes in metapopulation models with heterogeneous connectivity pattern. ...
We provide an explicit expression of the threshold that sets a critical value of the diffusion/mobility rate below which the epidemic is not able to spread to a macroscopic fraction of subpopulations. ...
The ratio hki 2 =hkk ÿ 1i is extremely small in heavy-tailed networks, and it is vanishing in the limit of infinite network size. ...
