We study the dynamics of information propagation in environments of low-overhead
personal publishing, using a large collection of weblogs over time as our example domain …

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 …

We address the problem of link reciprocity, the nonrandom presence of two mutual links
between pairs of vertices. We propose a new measure of reciprocity that allows the ordering …

Using data from computer databases of scientific papers in physics, biomedical research,
and computer science, we have constructed networks of collaboration between scientists in …

We present a study of information flow that takes into account the observation that an item
relevant to one person is more likely to be of interest to individuals in the same social circle …

527 process? Many MHC class I–binding peptides have been isolated and sequenced, and
no spliced peptides have previously been described. One could therefore argue that splicing …

Web caches, content distribution networks, peer-to-peer file sharing networks, distributed file
