Basic properties of real-world multiplex collaboration networks.

We report the number of nodes N, the average degree 〈k〉 and the clustering coefficient C for each layer of a subset of the APS and IMDb data sets. In particular, we focus on the multiplex collaboration network of all scientists active in Nuclear, Particle, Condensed Matter I and Interdisciplinary physics, and the multiplex collaboration network of all actors starring in Action, Crime, Romance and Thriller movies. All the layers of APS have a clustering coefficient C in the range [0.24, 0.30]. Conversely, the values of C of all the IMDb layers are in the range [0.56, 0.61].
