Discrete molecular dynamics studies of the folding of a protein-like model
Nikolay V. Dokholyan, Sergey V. Buldyrev, H. Eugene Stanley +1
Background: Many attempts have been made to resolve in time the folding of model proteins in computer simulations. Different computational approaches have emerged. Some of these ap…
Spontaneous Stratification in Granular Mixtures
Hernan A. Makse, Shlomo Havlin, Peter R. King +1
Granular materials size segregate when exposed to external periodic perturbations such as vibrations. Moreover, mixtures of grains of different sizes spontaneously segregate in the…
Mechanisms of Granular Spontaneous Stratification and Segregation in Two-Dimensional Silos
Pierre Cizeau, Hernan A. Makse, H. Eugene Stanley
Spontaneous stratification of granular mixtures has been reported by Makse et al. [Nature 386, 379 (1997)] when a mixture of grains differing in size and shape is poured in a quasi…
Dynamics of Granular Stratification
Hernan A. Makse, Robin C. Ball, H. Eugene Stanley +1
Spontaneous stratification in granular mixtures has been recently reported by H. A. Makse et al. [Nature 386, 379 (1997)]. Here we study experimentally the dynamical processes lead…
Possible Stratification Mechanism in Granular Mixtures
Hernan A. Makse, Pierre Cizeau, H. Eugene Stanley
We propose a mechanism to explain what occurs when a mixture of grains of different sizes and different shapes (i.e. different repose angles) is poured into a quasi-two-dimensional…
Universality in sandpiles
Alessandro Chessa, H. Eugene Stanley, Alessandro Vespignani +1
We perform extensive numerical simulations of different versions of the sandpile model. We find that previous claims about universality classes are unfounded, since the method prev…
