Why social networks are different from other types of networks.
It is demonstrated that group structure in networks can also account for degree correlations and that the predicted level of assortative mixing compares well with that observed in real-world networks.
High-Quality Binary Protein Interaction Map of the Yeast Interactome Network
A comparative quality assessment of current yeast interactome data sets is carried out, demonstrating that high-throughput yeast two-hybrid (Y2H) screening provides high-quality binary interaction information.
Statistical mechanics of networks.
We study the family of network models derived by requiring the expected properties of a graph ensemble to match a given set of measurements of a real-world network, while maximizing the entropy of…

It is shown that when nodes in a network belong to two distinct classes, two independent parameters are needed to capture the detailed interplay between the network structure and node properties, and it is found that thenetwork structure significantly limits the values of these parameters.

This work derives expressions for a number of quantities of interest in the p-star model and shows that the degenerate region of the parameter space observed in computer simulations is a spontaneously symmetry-broken phase separated from the normal phase of the model by a conventional continuous phase transition.
The impact of cellular networks on disease comorbidity
By combining information on cellular interactions, disease‐‐gene associations, and population‐level disease patterns extracted from Medicare data, statistically significant correlations between the underlying structure of cellular networks and disease comorbidity patterns in the human population are found.
Origin of degree correlations in the Internet and other networks.
The results confirm that the conjectured mechanism does indeed give rise to correlations of the kind seen in the Internet, although only a part of the measured correlation can be accounted for in this way.
A network-based ranking system for US college football
American college football faces a conflict created by the desire to stage national championship games between the best teams of a season when there is no conventional play-off system for deciding…
Solution for the properties of a clustered network.
We study Strauss's model of a network with clustering and present an analytic mean-field solution which is exact in the limit of large network size. Previous computer simulations have revealed a…
