GRAVITY, BILATERAL AGREEMENTS, AND TRADE DIVERSION IN THE AMERICAS

Metric-scalar gravity with torsion and the measurability of the non-minimal coupling
(World Scientific Publ Co Pte Ltd, 2007-04-30)
The measurability of the non-minimal coupling is discussed by considering the correction to the Newtonian static potential in the semiclassical approach. The coefficient of the gravitational Darwin term (GDT) gets redefined ...
Straight spinning cosmic strings in Brans-Dicke gravity
(2018-03-21)
An exact solution of straight spinning cosmic strings in Brans-Dicke theory of gravitation is presented. The possibility of the existence of closed time-like curves around these cosmic strings is analyzed. Furthermore, the ...
Addition of torsion to chiral gravity
(American Physical Society, 2011-06)
Three-dimensional gravity in anti-de Sitter space is considered, including torsion. The derivation of the central charges of the algebra that generates the asymptotic isometry group of the theory is reviewed, and a special ...
Accretion disks around black holes in scalar-tensor-vector gravity
(American Physical Society, 2017-05)
Scalar-tensor-vector gravity (STVG) is an alternative theory of gravitation that has successfully explained the rotation curves of nearby galaxies, the dynamics of galactic clusters, and cosmological data without dark ...
Observational constraints on a phenomenological f (R, partial derivative R)-model
(Springer, 2015-03-01)
This paper analyses the cosmological consequences of amodified theory of gravity whose action integral is built from a linear combination of the Ricci scalar R and a quadratic term in the covariant derivative of R. The ...
Holographic renormalization in teleparallel gravity
(Springer, 2017-01-24)
We consider the problem of IR divergences of the action in the covariant formulation of teleparallel gravity in asymptotically Minkowski spacetimes. We show that divergences are caused by inertial effects and can be removed ...
Estimation of gravity wave parameters to alleviate the delay in the Antarctic vortex breakup in general circulation models
(John Wiley & Sons Ltd, 2017-05-19)
The impact of optimal parameters in a non-orographic gravity wave drag parameterization on the middle atmosphere circulation of the Southern hemisphere is examined. Optimal parameters are estimated using a data assimilation ...
Estimation of optimal gravity wave parameters for climate models using data assimilation
(John Wiley & Sons Ltd, 2011-09)
There is a current need to constrain the parameters of gravity wave drag schemes in climate models using observational information instead of tuning them subjectively. In this work, an inverse technique is developed using ...
Scalar fluctuations of the scalar metric during inflation from a non-perturbative 5D large-scale repulsive gravity model
(Springer, 2013-10-16)
We develop a non-perturbative formalism for scalar metric fluctuations from a 5D extended version of General Relativity in vacuum. In this work we concentrate our efforts on calculations valid on large cosmological ...
