In this paper we present a cosmological model arising from a non-conservative gravitational theory proposed in [PRD 95, 101501(R) (2017)]. The novel feature where comparing with previous implementations of diss
gravity theory, where t is the trace of the energy-momentum tensor. for a recent review of the generalized \(f\left( r,l_{m}\right) \) and f ( r , t ) type gravitational theories with non-minimal curvature-matter coupling see [ 27 ]. several other gravitational theories ...
This result is expectable, because Rastall gravity is equivalent to GR in the vacuum case. 3 Noncommutative geometry inspired black holes Considering the noncommutativity of spacetime, the matter source can be diffused throughout a region, instead of locat- ing at a point. For the smeared ...
There is a great need to have the possibility of a near weightlessness environment for scientific and sometimes commercial or future tourist activities. A plausible configuration of a future space station should then be one with a rotating outer part to generate AG while the center remains non-...
The use of 3.5 median deviations here is a conservative choice, as it is expected that for some small lakes the water height change between timesteps (91 days for ICESat-2) could be large. It is important to note here that this running median does not account for the differences in ...
Most of Gravity's fundamental indicators, such as Revenue, are part of a valuation analysis module that helps investors searching for stocks that are currently trading at higher or lower prices than their real value. If the real value is higher than the market price, Gravity Co is considered ...
In a “conservative approach”, the two masses are coupled via Newtonian potential. As seen from our calculations and those in refs. 16,17 this indeed leads to gravitationally induced entanglement. In this picture, gravity is a direct interaction and hence it is difficult to draw conclusions ...
aggressive: Tc is the larger of 0.1·Tp or 0.8·Өp moderate:Tc is the larger of 1·Tp or8·Өp conservative:Tc is the larger of 10·Tp or 80·Өp Because the popular PID forms perform the same if properly tuned, the observations and conclusions we draw from any one algorithms...
The problem of describing the quantum behavior of gravity, and thus understanding quantum spacetime, is still open. Loop quantum gravity is a well-develope
The non- minimal coupling function Y (R) is dimensionless. Conse- quently every term in our Lagrangian has the dimension of (energy)(length). Finally we notice that the dimension of λa must be energy because torsion has the dimension of l engt h. After substituting the connection varied...
