Time variation of fundamental constants in nonstandard cosmological models
(American Physical Society, 2017-10)
In this work we have studied the lithium problem in nonstandard cosmological models. In particular, by using the public code alterbbn, we have included in the computation of the primordial light nuclei abundances, the ...
A FIRST-ORDER TIME CONSTANT ESTIMATION FOR NONLINEAR DIFFUSION PROBLEMS
(TAYLOR & FRANCIS INC, 2014-06-03)
A Laplace transform-based procedure was proposed to calculate the effective time constant for a class of nonlinear diffusion problems. The governing mathematical representation was first estimated with a linear model by ...
Constant-random practice and the adaptive process in motor learning with varying amounts of constant practice
(AMMONS SCIENTIFIC, LTD, 2010)
The adaptive process in motor learning was examined in terms of effects of varying amounts of constant practice performed before random practice. Participants pressed five response keys sequentially, the last one coincident ...
The effect of a constant or a declining discount rate on optimal investment timing
(Pontificia Universidad Católica de Chile, Instituto de Economía., 2002)
Formally verified countermeasures against cache based attacks in virtualization platforms
(UR.FI.INCO, 2016)
Cache based attacks are a class of side-channel attacks that are particularly effective in virtualized or cloud-based environments, where they have been used to recover secret keys from cryptographic implementations. One ...
Hypoprolactinemic rats under conditions of constant darkness or constant light. Effects on the sleep-wake cycle, cerebral temperature and sulfatoxymelatonin levels
(Elsevier B.V., 1999-07-24)
In genetic hypoprolactinemic rats under light-dark (LD) conditions, the circadian rhythms of slow-wave (SWS) and paradoxical (PS) sleep display an alteration of their phase relationship. the aim of our study was to investigate ...
On the effusion time of drugs from the open pore of a spherical vesicle
(ELSEVIER SCIENCE BV, 2016-06-01)
Solute permeation through a spherical liposomal vesicle was analyzed using Fick's second law and a mixed Neumann-Dirichlet boundary condition. The first-principles approach was necessary to help calculate the effusion time ...
