Consistency landscape of network communities
Daekyung Lee, Sang Hoon Lee, Beom Jun Kim +1
The concept of community detection has long been used as a key device for handling the mesoscale structures in networks. Suitably conducted community detection reveals various embe…
On structural and dynamical factors determining the integrated basin instability of power-grid nodes
Heetae Kim, Mi Jin Lee, Sang Hoon Lee +1
In electric power systems delivering alternating current, it is essential to maintain its synchrony of the phase with the rated frequency. The synchronization stability that quanti…
Relational flexibility of network elements based on inconsistent community detection
Heetae Kim, Sang Hoon Lee
Community identification of network components enables us to understand the mesoscale clustering structure of networks. A number of algorithms have been developed to determine the…
Generalized gravity model for human migration
Hye Jin Park, Woo Seong Jo, Sang Hoon Lee +1
The gravity model (GM) analogous to Newton's law of universal gravitation has successfully described the flow between different spatial regions, such as human migration, traffic fl…
Network nestedness as generalized core-periphery structures
Sang Hoon Lee
The concept of nestedness, in particular for ecological and economical networks, has been introduced as a structural characteristic of real interacting systems. We suggest that the…
Geometric properties of graph layouts optimized for greedy navigation
Sang Hoon Lee, Petter Holme
The graph layouts used for complex network studies have been mainly been developed to improve visualization. If we interpret the layouts in metric spaces such as Euclidean ones, ho…
