Candida albicans and Candida glabrata are opportunistic human pathogens that are the leading cause of fungal infections, which are increasingly becoming the leading cause of sepsis in immunosuppressed...
Nonnormal amplification in random balanced neuronal networks
Nonnormal amplification random balanced neuronal networks Neurons and Cognition
2012/4/28
In dynamical models of cortical networks, the recurrent connectivity can amplify the input given to the network in two distinct ways. One is induced by the presence of near-critical eigenvalues in the...
Selective pressure on metabolic network structures as measured from the random blind-watchmaker network
Selective pressure metabolic network structures measured random blind-watchmaker network
2010/11/15
A random null model termed the Blind Watchmaker network (BW) has been shown to reproduce the degree distribution found in metabolic networks. This might suggest that natural selection has had little i...
