Joint inversion of muon tomography and gravimetry - a resolving kernel approach [PDF]
, 2014 Both muon tomography and gravimetry are geophysical methods that provide information on the density structure of the Earth's subsurface. Muon tomography measures the natural flux of cosmic muons and its attenuation produced by the screening effect of the

Quantum mechanics of 4-derivative theories [PDF]
, 2015 A renormalizable theory of gravity is obtained if the dimension-less 4-derivative kinetic term of the graviton, which classically suffers from negative unbounded energy, admits a sensible quantisation.

Advances in techniques and applications of joint estimation by receiver function and gravity data
地球与行星物理论评, 2022 The joint inversion of receiver function and gravity data estimates the crustal thickness and VP/VS ratio. Since Lowry and Pérez-Gussinyé proposed it in 2011, this joint inversion method has been improved and refined by domestic and international ...

Temperature inversion in granular fluids under gravity
, 2002 We study, via hydrodynamic equations, the granular temperature profile of a granular fluid under gravity and subjected to energy injection from a base. It is found that there exists a turn-up in the granular temperature and that, far from the base, it ...

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]
, 2006 The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...
