New Findings from Queen Mary University in the Area of Physics Research Reported (Structural measures for multiplex networks)

July 8, 2014

By a News Reporter-Staff News Editor at Physics Week -- Investigators discuss new findings in Physics Research. According to news reporting out of London, United Kingdom, by VerticalNews editors, research stated, "Many real-world complex systems consist of a set of elementary units connected by relationships of different kinds. All such systems are better described in terms of multiplex networks, where the links at each layer represent a different type of interaction between the same set of nodes rather than in terms of (single-layer) networks."

Our news journalists obtained a quote from the research from Queen Mary University, "In this paper we present a general framework to describe and study multiplex networks, whose links are either unweighted or weighted. In particular, we propose a series of measures to characterize the multiplexicity of the systems in terms of (i) basic node and link properties such as the node degree, and the edge overlap and reinforcement, (ii) local properties such as the clustering coefficient and the transitivity, and (iii) global properties related to the navigability of the multiplex across the different layers."

According to the news editors, the research concluded: "The measures we introduce are validated on a genuinely multiplex data set of Indonesian terrorists, where information among 78 individuals are recorded with respect to mutual trust, common operations, exchanged communications, and business relationships."
