Studies from University of Bologna Have Provided New Information about Life Science Research (Weighted multiplex networks)

August 26, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Life Science Research is the subject of a report. According to news originating from Bologna, Italy, by NewsRx correspondents, research stated, "One of the most important challenges in network science is to quantify the information encoded in complex network structures. Disentangling randomness from organizational principles is even more demanding when networks have a multiplex nature."

Our news journalists obtained a quote from the research from the University of Bologna, "Multiplex networks are multilayer systems of [Formula: see text] nodes that can be linked in multiple interacting and co-evolving layers. In these networks, relevant information might not be captured if the single layers were analyzed separately. Here we demonstrate that such partial analysis of layers fails to capture significant correlations between weights and topology of complex multiplex networks. To this end, we study two weighted multiplex co-authorship and citation networks involving the authors included in the American Physical Society. We show that in these networks weights are strongly correlated with multiplex structure, and provide empirical evidence in favor of the advantage of studying weighted measures of multiplex networks, such as multistrength and the inverse multiparticipation ratio."

According to the news editors, the research concluded: "Finally, we introduce a theoretical framework based on the entropy of multiplex ensembles to quantify the information stored in multiplex networks that would remain undetected if the single layers were analyzed in isolation."

The news correspondents report that additional information may be obtained from G. Menichetti, Dept. of Physics and Astronomy and INFN Sez Bologna, Bologna University, Bologna, Italy. Additional authors for this research include D. Remondini, P. Panzarasa, R.J. Mondragon and G. Bianconi (see also Life Science Research).
