Relativistic viscous effects on the primordial gravitational waves spectrum
(IOP Publishing, 2021-06)
We study the impact of the viscous effects of the primordial plasma on the evolution of the primordial gravitational waves (pGW) spectrum from Inflation until today, considering a self-consistent interaction that incorporates ...
Perturbative treatment of the non-linear q-schrödinger and q-Klein-Gordon equations
(Molecular Diversity Preservation International, 2017-01)
Interesting non-linear generalization of both Schrödinger's and Klein-Gordon's equations have been recently advanced by Tsallis, Rego-Monteiro and Tsallis (NRT) in Nobre et al. (Phys. Rev. Lett. 2011, 106, 140601). There ...
Substitutional Ta-doping in Y2O3 semiconductor by sol-gel synthesis: Experimental and theoretical studies
(IOP Publishing, 2017-07)
The Pechini sol-gel method has been employed for the synthesis of pure and (181Hf→)181Ta-doped Y2O3 nanopowders. We performed a structural characterization from the micro to the subnanoscopic scale by means of scanning ...
Plausible binding mode of the active α4β1 antagonist, MK-0617, determined by docking and free energy calculations
(World Scientific, 2012-12)
In the last years, the development of small molecule antagonists of VLA-4 for the treatment of diseases, where cell tra±cking and activation are important, has increased considerably. Among them, the MK-0617 ligand has ...
On vacuum density, the initial singularity and dark energy
(Springer Verlag, 2009)
Standard cosmology poses a number of important questions. Apart from
its singular origin, it possesses early and late accelerating phases required to account
for observations. The vacuum energy has been considered as a ...
The position of the double bond in monounsaturated free fatty acids is essential for the inhibition of the nicotinic acetylcholine receptor
(Elsevier B.V., 2012)
Abstract: Free fatty acids (FFAs) are non-competitive antagonists of the nicotinic acetylcholine receptor (AChR). Their site of action is supposedly located at the lipid-AChR interface. To elucidate the mechanism involved ...
When the Casimir energy is not a sum of zero-point energies
(American Physical Soc, 2014)
Free-fall in a uniform gravitational field in noncommutative quantum mechanics
(AMER INST PHYSICS, 2010)
We study the free-fall of a quantum particle in the context of noncommutative quantum mechanics (NCQM). Assuming noncommutativity of the canonical type between the coordinates of a two-dimensional configuration space, we ...
