Absorbing phase transition with a continuously varying exponent in a quantum contact process: A neural network approach

Autor: Minjae Jo, Jongshin Lee, K. Choi, B. Kahng

Publikováno v: Physical Review Research, Vol 3, Iss 1, p 013238 (2021)

Phase transitions in dissipative quantum systems are intriguing because they are induced by the interplay between coherent quantum and incoherent classical fluctuations. Here, we investigate the crossover from a quantum to a classical absorbing phase

Prediction and mitigation of nonlocal cascading failures using graph neural networks

Autor: Bukyoung Jhun, Hoyun Choi, Yongsun Lee, Jongshin Lee, Cook Hyun Kim, B. Kahng

Cascading failures in electrical power grids, comprising nodes and links, propagate nonlocally. After a local disturbance, successive resultant can be distant from the source. Since avalanche failures can propagate unexpectedly, care must be taken wh

Betweenness centrality of teams in social networks

Autor: Jongshin Lee, Soo Min Oh, Yongsun Lee, Byungnam Kahng

Publikováno v: Chaos (Woodbury, N.Y.). 31(6)

Betweenness centrality (BC) was proposed as an indicator of the extent of an individual's influence in a social network. It is measured by counting how many times a vertex (i.e., an individual) appears on all the shortest paths between pairs of verti
