Physics Letters B, 1987 Abstract We look for a relation between the Christodoulakis-Zanelli Schwinger term in the commutators of the constraints and the Weyl diffeomorphism cocycle. We discuss the problem of anomalies in pure Quantum Gravity. We underline the particular role of the Weyl degree of freedom in all approaches to Quantum Gravity.

Combined use of the GGSFT data base and on Board Marine Collected Data to Model the Moho Beneath the Powell Basin, Antarctica [PDF]
, 2007 The Powell Basin is a small oceanic basin located at the NE end of the Antarctic Peninsula developed during the Early Miocene and mostly surrounded by the continental crusts of the South Orkney Microcontinent, South Scotia Ridge and Antarctic Peninsula ...

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Upward continuation of surface gravity anomalies [PDF]
, 1984 Investigations on the upward continuation of gravity anomalies given on the surface of the earth's visible topography are reported. Results are compared for three upward continuation procedures: first, the direct Poisson integration of the original ...

Inversion of Gravity Anomalies by a Hybrid Metaheuristic Algorithm [PDF]
In this work, we introduce application of a hybrid algorithm (DE/PSO) to estimate the model parameters from residual gravity anomalies due to some simple geometrical bodies.

Geological Journal, EarlyView.Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Statistical analysis of gravity anomalies [PDF]
, 1962 In the first part of this paper the author continues his research on the statistics of gravity anomalies. New and independent methods for computing the statistical functions Es and Gs are described.

Journal of the Chinese Chemical Society, EarlyView.While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Accurate gravity anomaly interpolation: a case-study in Cameroon, Central Africa
Earth Sciences Research Journal, 2007 Many treatments in geodesy and geophysics require regularly gridded gravity anomalies. The gridding of gravity data needs interpolation. For the predicted data to be accurate, the smoothest type of<br />gravity anomaly should be used along with the
