Universal patterns in sound amplitudes of songs and music genres
R. S. Mendes, H. V. Ribeiro, F. C. M. Freire +2
We report a statistical analysis over more than eight thousand songs. Specifically, we investigate the probability distribution of the normalized sound amplitudes. Our findings see…
Polycyclic Aromatic Hydrocarbon and Emission Line Ratios in Active Galactic Nuclei and Starburst Galaxies
Dinalva A. Sales, M. G. Pastoriza, R. Riffel
We study the Polycyclic Aromatic Hydrocarbons (PAH) bands, ionic emission lines, and Mid-infrared continuum properties, in a sample of 171 emission line galaxies taken from literat…
Gravitational constraints of dS branes in AdS Einstein-Brans-Dicke bulk
J. M. Hoff da Silva, Roldao da Rocha
We derive the full projected Einstein-Brans-Dicke gravitational equations associated with a n-dimensional brane embedded in a (n+1)-dimensional bulk. By making use of general condi…
Comment on "Wave functions for a Duffin-Kemmer-Petiau particle in a time-dependent potential"
L. B. Castro, A. S. de Castro
It is shown that the paper "Wave functions for a Duffin-Kemmer-Petiau particle in a time-dependent potential", by Merad and Bensaid [J. Math. Phys. 48, 073515 (2007)] is not correc…
Dynamics of tournaments: the soccer case
H. V. Ribeiro, R. S. Mendes, L. C. Malacarne +2
A random walk-like model is considered to discuss statistical aspects of tournaments. The model is applied to soccer leagues with emphasis on the scores. This competitive system wa…
