We discuss a recently introduced real space renormalization group (RSRG) approach. Unlike other RSRGs, it does not depend upon weight functions arisen from particular recipes like majority rule or others. Instead, it is formulated assuming only the validity of Fisher's finite size scaling...

We propose an experimental way to test theories concerning DNA evolution mechanisms, through computer simulations.

The finite size scaling renormalisation group (FSSRG) was introduced in Europhysics Letters 20 (1992) 621. Based only on the finite size scaling hypothesis, with no further assumptions, it differs from other real space renormalisation groups (RSRGs) in the following essential point: one does not...

Human history leaves fingerprints in human languages. Little is known about language evolution and its study is of great importance. Here we construct a simple stochastic model and compare its results to statistical data of real languages. The model is based on the recent finding that language...

Street demonstrations occur across the world. In Rio de Janeiro, in June/July 2013, they reach beyond one million people. A wrathful reader of O Globo, a leading newspaper in the same city, published a letter (Ferreira (2011)  [10]) where many social questions are stated and answered Yes or No....

In the ±J Edwards-Anderson spin glass, we find by Monte Carlo simulation the (approximate) ground state energy. Also we check how in the relaxation towards this ground state the fraction of never flipped spins diminishes with time.
