Higher-Derivative Gravity and the AdS/CFT Correspondence [PDF]
, 2001 We investigate the AdS/CFT correspondence for higher-derivative gravity systems, and develop a formalism in which the generating functional of the boundary field theory is given as a functional that depends only on the boundary values of bulk fields.

Anomalies in covariant W-gravity
Physics Letters B, 1991 Abstract We consider free scalar matter covariantly coupled to background W-gravity. Expanding to second order in the W-gravity fields, we study the appropriate anomalous Ward-Takahashi identities and find the counterterms which maintain diffeomorphism invariance and its W-analogue. We see that a redefinition of the vielbein transformation rule under

Correlation between the Bouguer gravity anomaly and the TAIGER tomography of the Taiwan region
Terrestrial, Atmospheric and Oceanic Sciences, 2018 The Bouguer gravity anomaly derived from observed gravity data and calculated from a 3-D P-wave velocity model were used to investigate the compatibility between the two to understand the crust structure of the Taiwan region.

Sum Vector-Difference-Based Matching Area Selection Method for Underwater Gravity-Aided Navigation
IEEE Access, 2019 For underwater gravity matching navigation, matching area selection has a significant impact on navigation accuracy. Since the changes of gravity anomaly between grids of gravity background map is different, when the underwater vehicle passes through the

Non‐Newtonian gravity or gravity anomalies? [PDF]
Eos, Transactions American Geophysical Union, 1988 We emphasize the importance of gravity anomalies in interpreting geophysical data, which has indicated a deviation from the Newtonian inverse square law. In particular, we point out that gravity anomalies, if not accounted for properly, mimic non‐Newtonian behavior. On the other hand, omitting them provides a false signal contributing to the “fifth” or

Structural map of Sulawesi derives from gravity data and its implications for geothermal systems [PDF]
E3S Web of Conferences, 2023 Gravity satellites are one of the alternatives to conducting preliminary surveys because the cost of exploring a large area using conventional gravity methods is very expensive and takes a lot of time.

Bouguer Anomaly of Central Cebu, Philippines
Journal of Maps, 2020 Cebu Island in Central Philippines consists of a Cretaceous basement complex capped by mostly Tertiary sedimentary units. Recent mapping conducted in Central Cebu revealed limited exposures of lithologies, especially those comprising the basement complex.
