Statistical Analysis of Global Connectivity and Activity Distributions in Cellular Networks (2010)

Beg, Qasim K., De Fabritiis, G., Villà-Freixa, Jordi

Various molecular interaction networks have been claimed to follow power-law decay for their global connectivity distribution. It has been proposed that there may be underlying generative models that...

A Semi-Supervised Method for Predicting Transcription Factor–Gene Interactions in Escherichia coli

Ernst, Jason, Beg, Qasim K., Kay, Krin A., Balázsi, Gábor, Oltvai, Zoltán N., Bar-Joseph, Ziv

While Escherichia coli has one of the most comprehensive datasets of experimentally verified transcriptional regulatory interactions of any organism, it is still far from complete. This presents a...
