Change and variability: A framework in studies on the first year of life
(Universidad Catolica de Colombia, 2013)
This article presents empirical evidence of variability and change in the performance of young children in causality tasks, highlighting the relevance of nonlinear perspective in studies about the first year of life. Using ...
Conformastatic disk-haloes in Einstein-Maxwell gravity
(2013)
We present a relativistic model describing a thin disk surrounded by a halo in the presence of an electromagnetic field. The model is obtained by solving the Einstein-Maxwell equations on a particular conformastatic spacetime ...
Fractional Fourier analysis of random signals and the notion of α -Stationarity of the Wigner-Ville distribution
(2013)
In this paper, a generalized notion of wide-sense α-stationarity for random signals is presented. The notion of stationarity is fundamental in the Fourier analysis of random signals. For this purpose, a definition of the ...
International technology adoption, R&D, and productivity growth
(Walter de Gruyter GmbH, 2013)
International knowledge diffusion is considered an important source of productivity growth. However, direct observations on such diffusion have not been available at the macro level. We analyze novel data on international ...

Extension of the B3LYP-dispersion-correcting potential approach to the accurate treatment of both inter-and intra-molecular interactions
(2013)
We recently demonstrated that dispersion-correcting potentials (DCPs), which are atom-centered Gaussian-type functions that were developed for use with B3LYP (Torres and DiLabio in J Phys Chem Lett 3:1738-1744, 2012), ...
Density-functional theory with dispersion-correcting potentials for methane: Bridging the efficiency and accuracy gap between high-level wave function and classical molecular mechanics methods
(2013)
Large clusters of noncovalently bonded molecules can only be efficiently modeled by classical mechanics simulations. One prominent challenge associated with this approach is obtaining force-field parameters that accurately ...
Leveraging speculative architectures for runtime program validation
(2013)
Program execution can be tampered with by malicious attackers through exploiting software vulnerabilities. Changing the program behavior by compromising control data and decision data has become the most serious threat in ...
Blind restoration of retinal images degraded by space-variant blur with adaptive blur estimation
(2013)
Retinal images are often degraded with a blur that varies across the gield view. Because traditional deblurring algorithms assume the blur to be space-invariant they typically fail in the presence of space-variant blur. ...
Development and/or change of the notion of permanent object and operative causality: Empirical evidence in the frst year of life
(Fundacion para el Avance de la Psicologia, 2013)
This study examines the notion of permanent object during the first year of life, taking into account the controversy of two approaches about the nature of change: developmental change and cognitive change. Using a ...
