Speed of complex network synchronization
Complex systems Synchronization coupled oscillators Synchronization in the nervous system
2011/9/14
Synchrony is one of the most common dynamical states emerging on networks. The speed of convergence towards synchrony provides a fundamental collective time scale for synchronizing systems. Here we st...
The Swiss Board Directors Network in 2009
Boards of directors Complex networks Corporate governance
2011/9/28
We study the networks formed by the directors of the most important Swiss boards and the boards themselves for the year 2009. The networks are obtained by projection from the original bipartite graph....
Robust network community detection using balanced propagation
community detection propagation
2011/9/6
Label propagation has proven to be an extremely fast method for detecting communities in large complex networks. Furthermore, due to its simplicity, it is also currently one of the most commonly adopt...
Sybil accounts are fake identities created to unfairly increase the power or resources of a singlemalicious user. Researchers have long known about the existence of Sybil accounts in online communitie...
Abstract—We show a simple method for constructing an infinite family of graph formation games with link bias so that the resulting games admits, as a pairwise
stable solution, a graph with an arbitra...
Composite Social Network for Predicting Mobile Apps Installation
Social Network Mobile Apps
2011/9/9
We have carefully instrumented a large portion of the population living in a university graduate dormitory by giving participants Android smart phones running our sensing software. In this paper, we p...
Network Diversity and Economic Development: a Comment
Network Diversity Economic Development
2010/11/16
Network diversity yields context-dependent benefits that are not yet fully-understood. I elaborate on a recently introduced distinction between tie strength diversity and information source diversity...
Genuine Tripartite Entanglement in a Spin-Star Network at Thermal Equilibrium
Genuine Tripartite Entanglement Spin-Star Network Thermal Equilibrium
2010/10/29
In a recent paper [M. Huber {\it et al}, Phys. Rev. Lett. {\bf 104}, 210501 (2010)] new criteria to find out the presence of multipartite entanglement have been given. We exploit these tools in order ...
Parameter Degeneracy in Neutrino Oscillation -- Solution Network and Structural Overview
Parameter Degeneracy Neutrino Oscillation Solution Network
2010/3/15
It is known that there is a phenomenon called "parameter degeneracy" in neutrino oscillation measurement of lepton mixing parameters; A set of the oscillation probabilities, e.g., P(nu_mu --> nu_e) an...
Experimental evidence for the interplay between individual wealth and transaction network
transaction networks dynamics of wealth accumulation
2010/4/27
We conduct a market experiment with human agents in order to explore the structure of transaction networks and to study the dynamics of wealth accumulation. The experiment is carried out on our platfo...
Nonextensivity in a memory network access mechanism
Consciousness-unconsciousness Neuroses Self-organized neural networks Boltzmann machine
2010/7/5
We have previously described neurotic psychopathology and psychoanalytic working-through by an associative memory mechanism, based on a neural network. Memory was initially modelled by a Boltzmann mac...
