A probe into dynamic measures for h-core and h-tail

Using the concepts of h-core and h-tail, shape descriptors and shape centroids, k-index and k′-index, dynamic measures are probed, with practical data in the fields of Physics and sociology. It is revealed that there are obvious differences between natural sciences (Physics, particles & fields) and social sciences (sociology) when c-descriptor, h-core centroid and k-index are applied as dynamic measures, while few differences exist when using t-descriptor, h-tail centroid and k′-index, following a time span from 1 to 10 years.

► Characterizing the dynamic structure of h-core and h-tail by using c-descriptor, t-descriptor, h-core centroid (cx, cy), h-tail centroid (tx, ty), k-index and k′-index. ► Integrating the dynamic measures for describing the evolutionary characteristics of h-core and h-tail. ► A special case study on the differences between natural sciences (physics) and social sciences (sociology) in evolutionary h-core and h-tail among time spans from one to ten years.
