The widespread relevance of increasingly complex networks requires methods to extract meaningful coarse-grained representations of such systems. For undirected graphs, standard community detection met...
The Moran model as a dynamical process on networks and its implications for neutral speciation
dynamical process networks implications
2011/1/5
In genetics the Moran model describes the neutral evolution of a bi-allelic gene in a population of haploid individuals subjected to mutations. We show in this paper that this model can be mapped into...
Information capacity and transmission are maximized in balanced cortical networks with neuronal avalanches
Information capacity transmission balanced cortical networks
2011/1/5
The repertoire of neural activity patterns that a cortical network can produce constrains the network's ability to transfer and process information. Here, we measured activity patterns obtained from m...
Some thoughts on the ontogenesis in B-cell immune networks
Some thoughts the ontogenesis B-cell immune networks
2011/1/5
We are interested in modeling theoretical immunology within a statistical mechanics flavor: focusing on the antigen-independent maturation process of B-cells, in this paper we try to revise the proble...
A network observed in a particular context may appear to have "unusual" properties. To quantify this, it is appropriate to randomize the network and test the hypothesis that the network is not statist...
Flows in complex biochemical networks: Role of low degree nodes
Flows complex biochemical networks low degree nodes
2011/1/5
Metabolic networks have two properties that are generally regarded as unrelated: One, they have metabolic reactions whose single knockout is lethal for the organism, and two, they have correlated sets...
Quantification and Minimization of Crosstalk Sensitivity in Networks
Quantification Minimization Crosstalk Sensitivity
2011/1/5
Crosstalk is defined as the set of unwanted interactions among the different entities of a network. Crosstalk is present in various degrees in every system where information is transmitted through a m...
A statistical method for revealing form-function relations in biological networks
statistical method revealing form-function relations biological networks
2011/1/5
Over the past decade, a number of researchers in systems biology have sought to relate the function of biological systems to their network-level descriptions -- lists of the most important players and...
The role of asymmetric interactions on the effect of habitat destruction in mutualistic networks
asymmetric interactions effect habitat destruction mutualistic networks
2010/11/15
Plant-pollinator mutualistic networks are asymmetric in their interactions: specialist plants are pollinated by generalist animals, while generalist plants are pollinated by a broad involving speciali...
Dynamic reconfiguration of human brain networks during learning
Dynamic reconfiguration human brain networks learning
2010/11/15
Human learning is a complex phenomenon requiring flexibility to adapt existing brain function and precision in selecting new neurophysiological activities to drive desired behavior. These two attribut...

Spatial Networks
2010/11/15
Complex systems are very often organized under the form of networks where nodes and edges are embedded in space. Transportation and mobility networks, Internet, mobile phone networks, power grids, so...
