, 2012 The aim of this work is to use the GOCE observations in a geologically unique part of the Himalayan orogen, which is the Kohistan arc. Here the entire section of the crust from the mantle-crust transition, to the volcanic deposits in the upper crust are ...

Modified Gravity and Coupled Quintessence [PDF]
, 2014 The distinction between modified gravity and quintessence or dynamical dark energy is difficult. Many models of modified gravity are equivalent to models of coupled quintessence by virtue of variable transformations. This makes an observational differentiation between modified gravity and dark energy very hard. For example, the additional scalar degree

Presentism and Quantum Gravity [PDF]
, 2001 There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics.

Gravitational wave memory in modified gravity theories
reservedAlthough the permanent distortions of spacetime after the passage of gravitational waves, a phenomenon predicted by Einstein’s General Relativity known as the gravitational wave memory effect, have not yet been observed, its detection is expected

Non-perturbative 3d Lorentzian quantum gravity [PDF]
, 2001 We have recently introduced a discrete model of Lorentzian quantum gravity, given as a regularized non-perturbative state sum over simplicial Lorentzian spacetimes, each possessing a uniqueWick rotation to Euclidean signature.

Quantum Gravity: Has Spacetime Quantum Properties? [PDF]
, 2009 The conceptual incompatibility between General Relativity and Quantum Mechanics is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - Quantum Mechanics gives a universally valid

Model selection for modified gravity
, 2011 In this article, we review model selection predictions for modified gravity scenarios as an explanation for the observed acceleration of the expansion history of the Universe.

International trade without CES : estimating translog gravity [PDF]
, 2010 This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more

Terrestrial water storage change from temporal gravity variation [PDF]
, 2009 Recent progress in accurately monitoring temporal gravity variations by means of superconducting gravimeters and satellite geodesy provides unprecedented opportunities in closing the water balance.
