Emergence of communities in weighted networks
J. M. Kumpula, J. -P. Onnela, J. Saramaki +2
Topology and weights are closely related in weighted complex networks and this is reflected in their modular structure. We present a simple network model where the weights are gene…
The International Trade Network: weighted network analysis and modelling
K. Bhattacharya, G. Mukherjee, J. Saramaki +2
Tools of the theory of critical phenomena, namely the scaling analysis and universality, are argued to be applicable to large complex web-like network structures. Using a detailed…
Limited resolution and multiresolution methods in complex network community detection
J. M. Kumpula, J. Saramaki, K. Kaski +1
Detecting community structure in real-world networks is a challenging problem. Recently, it has been shown that the resolution of methods based on optimizing a modularity measure o…
Anomalous lifetime distributions and topological traps in ordering dynamics
X. Castello, R. Toivonen, V. M. Eguiluz +3
We address the role of community structure of an interaction network in ordering dynamics, as well as associated forms of metastability. We consider the voter and AB model dynamics…
Emergence of self-sustained patterns in small-world excitable media
Sitabhra Sinha, Jari Saramaki, Kimmo Kaski
Motivated by recent observations that long-range connections (LRC) play a role in various brain phenomena, we have observed two distinct dynamical transitions in the activity of ex…
