How Nodes Pull Strings in Complex Networks (1 of 2) (IMAGE)
Caption
To control complex systems, Professors Ruths and Ruths identify levers -- parts of the system (e.g., proteins in cells and companies in markets) -- that can be used to influence the rest of the system. Control profiles, imaged here as triangular heatmaps, depict the breakdown of these leverage points based on three elements of network architecture. Despite the diversity of control profile signatures arising from real world systems, clusters form around these same three components and provide insight into the organization of these systems. This image relates to a paper that appeared in the 21 March, 2014, issue of Science, published by AAAS. The paper, by Justin Ruths, at Singapore University of Technology and Design in Singapore, and Derek Ruths, at McGill University in Montreal, QC, Canada, was titled, "Control Profiles of Complex Networks."
