Explosive synchronization enhanced by time-delayed coupling
Thomas Kauê Dal'Maso Peron, Francisco Aparecido Rodrigues
We study the emergence of synchronization in scale-free networks by considering the Kuramoto model of coupled phase oscillators. The natural frequencies of oscillators are assumed…
Collective behavior in financial market
Thomas Kauê Dal'Maso Peron, Francisco Aparecido Rodrigues
Financial market is an example of complex system, which is characterized by a highly intricate organization and the emergence of collective behavior. In this paper, we quantify thi…
Automatic Network Fingerprinting through Single-Node Motifs
Christoph Echtermeyer, Luciano da Fontoura Costa, Francisco A. Rodrigues +1
Complex networks have been characterised by their specific connectivity patterns (network motifs), but their building blocks can also be identified and described by node-motifs---a…
A Complex Networks Approach for Data Clustering
Francisco A. Rodrigues, Guilherme Ferraz de Arruda, Luciano da Fontoura Costa
Many methods have been developed for data clustering, such as k-means, expectation maximization and algorithms based on graph theory. In this latter case, graphs are generally cons…
