Avalanche dynamics driven by adaptive rewirings in complex networks
K. Rho, S. R. Hong, B. Kahng
We introduce a toy model displaying the avalanche dynamics of failure in scale-free networks. In the model, the network growth is based on the Barabási and Albert model and each no…
Lethality and synthetic lethality in the genome-wide metabolic network of Escherichia coli
C. -M. Ghim, K. -I. Goh, B. Kahng
Recent genomic analyses on the cellular metabolic network show that reaction flux across enzymes are diverse and exhibit power-law behavior in its distribution. While one may guess…
Evolution of scale-free random graphs: Potts model formulation
D. -S. Lee, K. -I. Goh, B. Kahng +1
We study the bond percolation problem in random graphs of weighted vertices, where each vertex has a prescribed weight and an edge can connect vertices and wi…
Sandpile avalanche dynamics on scale-free networks
D. -S. Lee, K. -I. Goh, B. Kahng +1
Avalanche dynamics is an indispensable feature of complex systems. Here we study the self-organized critical dynamics of avalanches on scale-free networks with degree exponent …
On the evolution of scale-free graphs
D. -S. Lee, K. -I. Goh, B. Kahng +1
We study the evolution of random graphs where edges are added one by one between pairs of weighted vertices so that resulting graphs are scale-free with the degree exponent . We…
Evolution of the Protein Interaction Network of Budding Yeast: Role of the Protein Family Compatibility Constraint
K. -I. Goh, B. Kahng, D. Kim
Understanding of how protein interaction networks (PIN) of living organisms have evolved or are organized can be the first stepping stone in unveiling how life works on a fundament…
