Fractal properties of isolines at varying altitude reveal different dominant geological processes on Earth
Andrea Baldassarri, Marco Montuori, Olga Prieto-Ballesteros +1
Geometrical properties of landscapes result from the geological processes that have acted through time. The quantitative analysis of natural relief represents an objective form of…
Stochastic dynamics of a sheared granular medium
Alberto Petri, Andrea Baldassarri, Fergal Dalton +3
We experimentally investigate the response of a sheared granular medium in a Couette geometry. The apparatus exhibits the expected stick-slip motion and we probe it in the very int…
Vocabulary growth in collaborative tagging systems
Ciro Cattuto, Andrea Baldassarri, Vito D. P. Servedio +1
We analyze a large-scale snapshot of del.icio.us and investigate how the number of different tags in the system grows as a function of a suitably defined notion of time. We study t…
Self-Organized Percolation Power Laws with and without Fractal Geometry in the Etching of Random Solids
Agnes Desolneux, Bernard Sapoval, Andrea Baldassarri
Classically, percolation critical exponents are linked to the power laws that characterize percolation cluster fractal properties. It is found here that the gradient percolation po…
Non-equilibrium Monte Carlo dynamics of the Sherrington-Kirkpatrick mean field spin glass model
Andrea Baldassarri
We present a numerical study of the non-equilibrium dynamics of the Sherrington-Kirkpatrick model. We analize the overlap distribution between the configurations visited at the tim…
