Before revision: In recent years, there is an increased interest in the role of static properties of and dynamics on signed graphs in physical, biological, and social networks.
After revision: Detecting and evaluating regions of brain under various circumstances is one of the most interesting topics in computational neuroscience. However, the majority of the studies on detecting communities of a functional connectivity network of the brain is done on networks obtained from coherency attributes, and not from correlation. This lack of studies, in part, is due to the role of static properties of and dynamics on signed graphs in physical, biological, and social networks.
