Species Abundances Distribution in Neutral Community Models
Z. Neda, M. Ravasz
An analytical approximation is derived for the Zero Sum Multinomial distribution which gives the Species Abundance Distribution in Neutral Community Models. The obtained distributi…
The Species Abundances Distribution in a new perspective
M. Ravasz, A. Balog, V. Marko +1
Studies on distribution, abundance and diversity of species revealed fascinating universalities in macroecology. Many of these patterns, like the species-area and range-abundance r…
Percolation-like behavior of some optimal coalition formation models
Z. Neda, R. Florian, M. Ravasz +2
The ground-state of an infinite-range Potts glass-type model with +/- J bonds and unrestricted number of states is used to investigate coalition formation. As a function of the q p…
Improved percolation thresholds for rods in three-dimensional boxes
R. Florian, Z. Neda
We improve our previous results for the percolation thresholds of isotropically oriented rods in three dimensional boxes. We prove again the applicability of the excluded volume ru…
Spiral cracks without twisting
K-t. Leung, L. Jozsa, M. Ravasz +1
A fascinating class of patterns, often encountered in nature as meandering cracks on rocks, dried-out fields and tectonic plates is produced by the fracture of solids. Here we repo…
Computer simulation of the microstructure and rheology of semi-solid alloys under shear
M. Perez, J-C. Barbe, Z. Neda +2
The rheological behavior of metallic alloys containing both solid and liquid phases is investigated in the low solid fraction range (<50%). This behavior depends on both the solid…
