QED from six-dimensional vortex and gauge anomalies [PDF]
, 2003 Starting from an anomaly-free Abelian Higgs model coupled to gravity in a 6-dimensional space-time we construct an effective four-dimensional theory of charged fermions interacting with U(1) Abelian gauge field and gravity, both localised near the core ...

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.

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

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.

Mare Orientale Gravity Anomaly [PDF]
Nature, 1970 SJOGREN has reported that there is an annular negative gravity anomaly surrounding a small positive anomaly over the central basin of Mare Orientale (paper given at the NATO Advanced Study Institute on the Moon and Planets, Newcastle, April 1970). I should like to point out that outside this negative ring, there is a positive ring and perhaps further ...

Radar ranging and Doppler tracking in post-Einsteinian metric theories of gravity [PDF]
, 2006 The study of post-Einsteinian metric extensions of general relativity (GR), which preserve the metric interpretation of gravity while considering metrics which may differ from that predicted by GR, is pushed one step further.

International Journal of Geophysics, 2012 A new gravity data compilation for Venezuela was processed and homogenized. Gravity was measured in reference to the International Gravity Standardization Net 1971, and the complete Bouguer anomaly was calculated by using the Geodetic Reference System ...

Fault Strike Detection Using Satellite Gravity Data Decomposition by Discrete Wavelets: A Case Study from Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2019 Estimating the gravity anomaly causative bodies boundary can facilitate the gravity field interpretation. In this paper, 2D discrete wavelet transform (DWT) is employed as a method to delineate the boundary of the gravity anomaly sources.

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

Entanglement Entropy for Logarithmic Conformal Field Theory [PDF]
, 2014 We study holographic entanglement entropy for certain logarithmic conformal field theories by making use of their gravity descriptions. The corresponding gravity descriptions are provided by higher derivative gravity at critical points where the ...
