Comparative Study on Predicting Topography from Gravity Anomaly and Gravity Gradient Anomaly [PDF]

open access: yesRemote Sensing, 2023
Owing to the dependence of algorithms on the measurement of ship soundings and geophysical parameters, the accuracy and coverage of topography still need to be improved. Previous studies have mostly predicted topography using gravity or gravity gradient,

Altered orientation and flight paths of pigeons reared on gravity anomalies: a GPS tracking study. [PDF]

open access: yesPLoS ONE, 2013
The mechanisms of pigeon homing are still not understood, in particular how they determine their position at unfamiliar locations. The "gravity vector" theory holds that pigeons memorize the gravity vector at their home loft and deduct home direction and

GRAVITY ANOMALIES OF THE MOON [PDF]

open access: yesInterCarto. InterGIS, 2015
The source of gravity anomalies of the Moon are large mascons with a high mass concentration at a depth of volcanic plains and lunar Maria. New data on the gravitational field of the Moon were obtained from two Grail spacecrafts. The article presents the

Refining satellite Altimetry-Derived gravity anomaly model with shipborne gravity using multilayer perceptron neural networks [PDF]

open access: yesScientific Reports
This study refines the gravity anomaly model derived from altimetry data by employing a multilayer perceptron (MLP) neural network to integrate multi-source geophysical data (longitude, latitude, gravity anomaly, geoid height, bathymetry, and sediment ...

Gravity dual of the chiral anomaly [PDF]

open access: yesPhysical Review D, 2002
We study effects associated with the chiral anomaly for a cascading $SU(N+M)\times SU(N)$ gauge theory using gauge/gravity duality. In the gravity dual the anomaly is a classical feature of the supergravity solution, and the breaking of the U(1) R-symmetry down to ${\bf Z}_{2M}$ proceeds via the Higgs mechanism.

Probing depth origin of gravity anomalies in Taiwan through 3-D coherent velocity model

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2021
We constructed a 3-D coherent velocity model by extracting the common features from recent tomographic models and utilized the forward gravity modeling and wavelength filtering method to explore the depth origin of the gravity anomalies, such as the long-
