The number of open paths in an oriented rho-percolation model
(SPRINGER, 2008)
We study the asymptotic properties of the number of open paths of length n in an oriented rho-percolation model. We show that this number is e(n alpha(rho)(1+o(1))) as n ->infinity. The exponent alpha is deterministic, it ...
Oriented Percolation in One-dimensional 1/vertical bar x-y vertical bar(2) Percolation Models
(SPRINGER, 2010)
We consider independent edge percolation models on Z, with edge occupation probabilities. We prove that oriented percolation occurs when beta > 1 provided p is chosen sufficiently close to 1, answering a question posed in ...
Percolation of polyatomic species on a simple cubic lattice
(Springer, 2013-09-25)
In the present paper, the site-percolation problem corresponding to linear k-mers (containing k identical units, each one occupying a lattice site) on a simple cubic lattice has been studied. The k-mers were irreversibly ...
Dependence of the percolation threshold on the size of the percolating species
(Elsevier Science, 2003-09-01)
Site and bond percolation of k-mers of different structures and forms deposited on 2-D regular lattices is studied. In addition, the percolation threshold for percolating k-mers on a Bethe lattice is analytically obtained. ...

Bootstrap percolation on homogeneous trees has 2 phase transitions
(SPRINGER, 2008)
We study the threshold theta bootstrap percolation model on the homogeneous tree with degree b + 1, 2 <= theta <= b, and initial density p. It is known that there exists a nontrivial critical value for p, which we call ...
Strict Majority Bootstrap Percolation in the r-wheel
(Elsevier, 2014)
In the strict Majority Bootstrap Percolation process each passive vertex v becomes active if at least [fórmula] of its neighbors are active (and thereafter never changes its state). We address the problem of finding graphs ...
Wall effects on the percolation of small grains in 2D ensembles
(Elsevier Science, 2004-06-15)
This work studies the dependence of percolation properties of bidimensional arrays of polydispersed disks on the distance separating the walls of the container holding them. Data for percolation probabilities using different ...
Selection of X chromosome of buffaloes sperm with Percoll gradients
(Pagepress Publ, 2007-01-01)
The aim of the present study was to evaluate the selection of X chromosome of buffaloes sperm with Percoll gradients. The stock solution of Percoll was prepared in the proportion of 1:11 (1 part of Percoll:11 parts of a ...
