Gate Control Improves Routing Efficiency for Periodic Traffic
Hyunwook Song, Hoyun Choi, B. Kahng
Traffic movement on highways and data packet transmission across the Internet serve as prototypical examples of collective dynamical behavior in complex systems. Although enhancing…
Unified framework for hybrid percolation transitions based on microscopic dynamics
Hoyun Choi, Y. S. Cho, Raissa D'Souza +2
A hybrid percolation transition (HPT) exhibits both discontinuity of the order parameter and critical behavior at the transition point. Such dynamic transitions can occur in two wa…
Heterogeneous Mean First-Passage Time Scaling in Fractal Media
Hyun-Myung Chun, Sungmin Hwang, Byungnam Kahng +2
The mean first passage time~(MFPT) of random walks is a key quantity characterizing dynamic processes on disordered media. In a random fractal embedded in the Euclidean space, the…
-core decomposition of hypergraphs
Jongshin Lee, Kwang-Il Goh, Deok-Sun Lee +1
In complex networks, many elements interact with each other in different ways. A hypergraph is a network in which group interactions occur among more than two elements. In this stu…
Prediction and mitigation of nonlocal cascading failures using graph neural networks
Bukyoung Jhun, Hoyun Choi, Yongsun Lee +3
Cascading failures (CFs) in electrical power grids propagate nonlocally; After a local disturbance, the second failure may be distant. To study the avalanche dynamics and mitigatio…
Resolving mean-field solutions of dissipative phase transitions using permutational symmetry
Minjae Jo, Bukyoung Jhun, B. Kahng
Phase transitions in dissipative quantum systems have been investigated using various analytical approaches, particularly in the mean-field (MF) limit. However, analytical results…
