On the consistency conditions to braneworlds in scalar-tensor gravity for arbitrary dimensions
(2009-12-01)
We derive an one-parameter family of consistency conditions to braneworlds in the Brans-Dicke gravity. The General Relativity case is recovered by taking a correct limit of the Brans-Dicke parameter. We show that it is ...

Learning processes and the neural analysis of conditioning
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2010)
Classical and operant conditioning principles, such as the behavioral discrepancy-derived assumption that reinforcement always selects antecedent stimulus and response relations, have been studied at the neural level, ...
The effects of environmental enrichment and social isolation and their reversion on anxiety and fear conditioning
(2019-01)
Animal models of fear and anxiety provide important insight into anxiety-related symptoms in humans.
Environmental physical conditions and social contact influence behavior and brain plasticity particularly at early ...

Second order necessary and sufficient optimality conditions for singular solutions of partially-affine control problems
(2017-03-02)
In this article we study optimal control problems for sys- tems that are affine with respect to some of the control variables and nonlinear in relation to the others. We consider finitely many equality and inequality ...
Health indices of green turtle (Chelonia mydas) along the pacific coast of Baja California Sur, Mexico. II. Body condition index
(Chelonian Conservation and Biology, 2010)
Body condition index is used as a measure for an individual’s condition, usually with reference to its nutritional status and the energy reserves. Reproductive success, survival, and thus, population dynamics, depend on ...
