Percolation in real Wildfires
Guido Caldarelli, Raffaella Frondoni, Andrea Gabrielli +3
This paper focuses on the statistical properties of wild-land fires and, in particular, investigates if spread dynamics relates to simple invasion model. The fractal dimension and…
Statistical properties of fractures in damaged materials
A. Gabrielli, R. Cafiero, G. Caldarelli
We introduce a model for the dynamics of mud cracking in the limit of of extremely thin layers. In this model the growth of fracture proceeds by selecting the part of the material…
Branching Processes and Evolution at the Ends of a Food Chain
G. Caldarelli, C. Tebaldi, A. L. Stella
In a critically self--organized model of punctuated equilibrium, boundaries determine peculiar scaling of the size distribution of evolutionary avalanches. This is derived by an in…
Memory and Self Organization
Matteo Marsili, Guido Caldarelli
The main result of this letter is that SOC naturally arises as a result of memory effects. We show that memory effects provide the mechanism for self organization. A general proced…
