Temporal Degree-Degree and Closeness-Closeness: A New Centrality Metrics for Social Network Analysis
Mathematics, 2021 In the area of network analysis, centrality metrics play an important role in defining the “most important” actors in a social network. However, nowadays, most types of networks are dynamic, meaning their topology changes over time.

The alterations of degree centrality in the frontal lobe of patients with panic disorder. [PDF]
Int J Med Sci, 2022 Objective: The brain network in panic disorder (PD) is still an intriguing issue for research. In this study, we hoped to investigate the role of DC (degree centrality) for the pathophysiology of PD, especially for the fear network.

Using network centrality measures to manage landscape connectivity [PDF]
, 2008 We use a graph-theoretical landscape modeling approach to investigate how to identify central patches in the landscape as well as how these central patches influence (1) organism movement within the local neighborhood, and (2) the dispersal of organisms ...
