1. Genetic programming: crossover operators, building blocks and semantic emergence / Programação genética: operadores de crossover, blocos construtivos e emergência semântica
Evolutionary algorithms are heuristic methods used to find solutions to optimization problems. These methods use stochastic search mechanisms inspired by Natural Selection Theory. Genetic Algorithms and Genetic Programming are two of the most popular evolutionary algorithms. These techniques make intensive use of crossover operators, a mechanism responsible

2. Neural activity during Stroop colour-word task performance in late proficient bilinguals: a functional magnetic resonance imaging study
The aim of this study was to identify which neural substrates are engaged during manual Stroop task performance and compare the activation between 8 late proficient Macedonian-English bilinguals and 10 matched English monolinguals. During functional magnetic resonance imaging (fMRI) adult participants performed four Stroop task conditions in a block design (

3. Entre a voz e a letra : a argumentação nos resumos dos depoimentos judiciais / Between the voice and the letter : argumentation in the summaries of judicial depositions
Based on the basic tenet of the Argumentative Semantics, according to which argumentation is enrolled in the language, this study investigates the presence of such argumentative marks in the summary produced by the judge, when converting into text the interrogatory by him conducted, following the rules of the Brazilian procedural system. As for the oral inte

4. A New Approach to Reduce Control Messages in Failure Detectors / UMA NOVA ABORDAGEM PARA REDUÇÃO DE MENSAGENS DE CONTROLE EM DETECTORES DE DEFEITOS
An unreliable failure detector is a basic building block widely used to implement fault tolerance techniques in asynchronous distributed systems. The use of failure detectors comes from the impossibility to implement deterministic agreement protocols in these environments, since it is not possible to distinguish a crashed process from a very slow process. Ho

5. Functional deactivations: Change with age and dementia of the Alzheimer type
Young adults typically deactivate specific brain regions during active task performance. Deactivated regions overlap with those that show reduced resting metabolic activity in aging and dementia, raising the possibility of a relation. Here, the magnitude and dynamic temporal properties of these typically deactivated regions were explored in aging by using fu
