Fundamental statistical features and self-similar properties of tagged networks (2008)

Palla, Gergely, Farkas, Illes J., Pollner, Peter, Derenyi, Imre, Vicsek, Tamas

We investigate the fundamental statistical features of tagged (or annotated) networks having a rich variety of attributes associated with their nodes. Tags (attributes, annotations, properties,...

Centrality properties of directed module members in social networks (2008)

Pollner, Peter, Palla, Gergely, Abel, Daniel, Vicsek, Andras, Farkas, Illes J., Derenyi, Imre, ...

Several recent studies of complex networks have suggested algorithms for locating network communities, also called modules or clusters, which are mostly defined as groups of nodes with dense internal...

Directed network modules (2007)

Palla, Gergely, Farkas, Illes J., Pollner, Peter, Derenyi, Imre, Vicsek, Tamas

A search technique locating network modules, i.e., internally densely connected groups of nodes in directed networks is introduced by extending the Clique Percolation Method originally proposed for...

Weighted network modules (2007)

Farkas, Illes J., Abel, Daniel, Palla, Gergely, Vicsek, Tamas

The inclusion of link weights into the analysis of network properties allows a deeper insight into the (often overlapping) modular structure of real-world webs. We introduce a clustering algorithm...

Topological basis of signal integration in the transcriptional-regulatory network of the yeast, Saccharomyces cerevisiae (2006)

Farkas, Illes J., Wu, Chuang, Chennubhotla, Chakra, Bahar, Ivet, Oltvai, Zoltan N.

BACKGROUND. Signal recognition and information processing is a fundamental cellular function, which in part involves comprehensive transcriptional regulatory (TR) mechanisms carried out in response...

CFinder: Locating cliques and overlapping modules in biological networks (2006)

Adamcsek, Balazs, Palla, Gergely, Farkas, Illes J., Derenyi, Imre, Vicsek, Tamas

Summary: Most cellular tasks are performed not by individual proteins, but by groups of functionally associated proteins, often referred to as modules. In a protein assocation network modules appear...

Initiating a Mexican wave: An instantaneous collective decision with both short and long range interactions (2006)

Farkas, Illes J., Vicsek, Tamas

An interesting example for collective decision making is the so-called Mexican wave during which the spectators in a stadium leap to their feet with their arms up and then sit down again following...

Spectra of "Real-World" Graphs: Beyond the Semi-Circle Law (2001)

Farkas, Illes J., Derenyi, Imre, Barabasi, Albert-Laszlo, Vicsek, Tamas

Many natural and social systems develop complex networks, that are usually modelled as random graphs. The eigenvalue spectrum of these graphs provides information about their structural properties....
