The coalescing colony model: mean-field, scaling, and geometry
Giulia Carra, Kirone Mallick, Marc Barthelemy
We analyze the coalescing model where a `primary' colony grows and randomly emits secondary colonies that spread and eventually coalesce with it. This model describes population pr…
Detecting Robust Patterns in the Spread of Epidemics: A Case Study of Influenza in the United States and France
Pascal Crépey, Marc Barthélemy
In this paper, the authors develop a method of detecting correlations between epidemic patterns in different regions that are due to human movement and introduce a null model in wh…
Global disease spread: statistics and estimation of arrival times
Aurelien Gautreau, Alain Barrat, Marc Barthelemy
We study metapopulation models for the spread of epidemics in which different subpopulations (cities) are connected by fluxes of individuals (travelers). This framework allows to d…
Arrival Time Statistics in Global Disease Spread
Aurelien Gautreau, Alain Barrat, Marc Barthelemy
Metapopulation models describing cities with different populations coupled by the travel of individuals are of great importance in the understanding of disease spread on a large sc…
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…
