Quantifying the taxonomic diversity in real species communities
C. Caretta Cartozo, D. Garlaschelli, C. Ricotta +2
We analyze several florae (collections of plant species populating specific areas) in different geographic and climatic regions. For every list of species we produce a taxonomic cl…
Resolution limit in community detection
Santo Fortunato, Marc Barthelemy
Detecting community structure is fundamental to clarify the link between structure and function in complex networks and is used for practical applications in many disciplines. A su…
Vulnerability of weighted networks
Luca Dall'Asta, Alain Barrat, Marc Barthelemy +1
In real networks complex topological features are often associated with a diversity of interactions as measured by the weights of the links. Moreover, spatial constraints may as we…
Epidemic variability in complex networks
Pascal Crépey, Fabián P. Alvarez, Marc Barthélemy
We study numerically the variability of the outbreak of diseases on complex networks. We use a SI model to simulate the disease spreading at short times, in homogeneous and in scal…
Optimal Traffic Networks
Marc Barthelemy, Alessandro Flammini
Inspired by studies on the airports' network and the physical Internet, we propose a general model of weighted networks via an optimization principle. The topology of the optimal n…
