Universality in the distribution of caustics in the expanding Universe

, 2003
We numerically investigate the long--time evolution of density perturbations after the first appearance of caustics in an expanding cosmological model with one--dimensional `single--wave' initial conditions.

VVV Survey Near-Infrared Photometry of Known Bulge RR Lyrae stars: the Distance to the Galactic Center and Absence of a Barred Distribution of the Metal-Poor Population

, 2013
We have combined optical and near-infrared data of known RR Lyrae (RRL) stars in the bulge in order to study the spatial distribution of its metal-poor component by measuring precise reddening values and distances of 7663 fundamental-mode RRL stars with ...

Large-scale periodicity in the distribution of QSO absorption-line systems

, 2010
The spatial-temporal distribution of absorption-line systems (ALSs) observed in QSO spectra within the cosmological redshift interval z = 0.0--4.3 is investigated on the base of our updated catalog of absorption systems.

Mapeando a fecundidade nordestina: 2000-2010

Confins, 2017
The results of the 2010 Demographic Census show that, among the three most populous Brazilian regions (representing more than 80% of the Brazilian population), the Northeast was the region registering the highest rate of population growth between 2000 ...

Individual-based lattice model for spatial spread of epidemics

, 2001
We present a lattice gas cellular automaton (LGCA) to study spatial and temporal dynamics of an epidemic of SIR (susceptible-infected-removed) type. The automaton is fully discrete, i.e. space, time and number of individuals are discrete variables.

Spatial Distribution of Competing Ions around DNA in Solution

, 2004
The competition of monovalent and divalent cations for proximity to negatively charged DNA is of biological importance and can provide strong constraints for theoretical treatments of polyelectrolytes.
