Forms of vitality play and symbolic play during the third year of life
(Elsevier, 2015-08)
This article focuses on the development of forms of vitality play, a recently described type of play, and links it to the development of symbolic play, one of the most studied types of play in developmental psychology. Two ...

(2016)
In January 2016, the first publicized decision made by the president of the newly installed Venezuelan parliament, Henry Ramos Allup, was the removal of pictures from the legislative premises. In what transpired as a ...
Symbolic analysis of heart rate variability and its interaction with p-value of normality tests applied on RR intervals
(Mavera Edições Técnicas e Científicas Ltda, 2016-04-01)
OBJECTIVE: A previous study suggested that the p-value of normality test applied to RR intervals is an index able to quantify Heart Rate Variability (HRV) through correlation of traditional time and frequency domain indices. ...
Central extensions of the algebra of formal pseudo-differential symbols via Hochschild (co)homology and quadratic symplectic Lie algebras
(2017)
We describe the space of central extensions of the associative algebra Ψn of formal pseudo-differential symbols in n≥1 independent variables using Hochschild (co)homology groups: we prove that the first Hochschild (co)homology ...

Symbolic algebra development for higher-order electron propagator formulation and implementation
(2014)
Through the use of symbolic algebra, implemented in a program, the algebraic expression of the elements of the self-energy matrix for the electron propagator to different orders were obtained. In addition, a module for the ...
