Rosvall (1 and 2), ( NORDITA, Copenhagen, Denmark, Department of Theoretical Physics, Umea University, Sweden | | Abstract: | Signaling pathways and networks determine the ability to communicate in systems ranging from living cells to human society. We investigate how the network structure constrains communication in social-, man-made and biological networks. We find that human networks of governance and collaboration are predictable on teat-a-teat level, reflecting well defined pathways, but globally inefficient. In contrast, the Internet tends to have better overall communication abilities, more alternative pathways, and is therefore more robust. Between these extremes the molecular network of Saccharomyces cerevisea is more similar to the simpler social systems, whereas the pattern of interactions in the more complex Drosophilia melanogaster, resembles the robust Internet. | | Source: | arXiv, cond-mat/0407055 | | Services: | Forum | Review | PDF | Favorites | |
