To investigate the geography of human relationships, a […]

Topologies of Linux and E. coli Control Networks

Comparing genomes to computer operating systems in terms of the topology and evolution of their regulatory control networks

A comparison of the Linux call graph hierarchy with the E. coli regulatory network. Researchers at Yale discovered that the Linux control structure is top-heavy, with a few common modules reused often. E coli, by contrast, has limited central control with many specialized “workers” at the bottom of the hierarchy.
