An iterative Wiener filtering method based on the gravity gradient invariants
Geodesy and Geodynamics, 2015 How to deal with colored noises of GOCE (Gravity field and steady – state Ocean Circulation Explorer) satellite has been the key to data processing. This paper focused on colored noises of GOCE gradient data and the frequency spectrum analysis. According

An Expression for Gravity Generated by an Anomalous Geological Body and Its Application in Bathymetry Inversion [PDF]
Journal of Geodesy and Geoinformation Science, 2021 The gravity anomaly and vertical gravity gradient due to anomalous geological bodies are mainly computed by numerical methods, so it is difficult and time-consuming to use the gravity-geological method to invert seafloor topography.

Human gravity-gradient noise in interferometric gravitational-wave detectors [PDF]
, 1999 Among all forms of routine human activity, the one which produces the strongest gravity-gradient noise in interferometric gravitational-wave detectors (e.g. LIGO) is the beginning and end of weight transfer from one foot to the other during walking.

An Aided Navigation Method Based on Strapdown Gravity Gradiometer
Sensors, 2021 The gravity gradient is the second derivative of gravity potential. A gravity gradiometer can measure the small change of gravity at two points, which contains more abundant navigation and positioning information than gravity.

Generalized gravity-gradient mitigation scheme [PDF]
Physical Review A, 2021 A major challenge in high-precision light-pulse atom interferometric experiments such as in tests of the weak equivalence principle is the uncontrollable dependency of the phase on initial velocity and position of the atoms in the presence of inhomogeneous gravitational fields.

Nonlinear superhorizon perturbations in Horava-Lifshitz gravity
, 2011 We perform a fully nonlinear analysis of superhorizon perturbation in Ho\v{r}ava-Lifshitz gravity, based on the gradient expansion method. We present a concrete expression for the solution of gravity equations up to the second order in the gradient ...

Measurement of the SOC State Specific Heat in ^4He [PDF]
, 2006 When a heat flux Q is applied downward through a sample of liquid 4He near the lambda transition, the helium self organizes such that the gradient in temperature matches the gravity induced gradient in Tlambda. All the helium in the sample is then at the
