Augmented Gravity Field Modelling by Combining EIGEN_6C4 and Topographic Potential Models
Remote Sensing, 2023 One of the key goals of geodesy is to study the fine structure of the Earth’s gravity field and construct a high-resolution gravity field model (GFM). Aiming at the current insufficient resolution problem of the EIGEN_6C4 model, the refined ultra-high ...

Macedonia's Exports and the Gravity Model [PDF]
SSRN Electronic Journal, 2013 This paper examines the export performance of the Republic of Macedonia to its main trading partners; hence we focus on the major importing countries which are most present in the Macedonian trade balance. The data used in this article are analyzed with gravity model, which has good characteristics and very stable performance.

A Fast Forward and Inversion Strategy for Three-Dimensional Gravity Field
Mathematics, 2023 Obtaining a three-dimensional (3D) density distribution within a reasonable time is one of the most critical problems in gravity exploration. In this paper, we present an efficient 3D forward modeling and inversion method for gravity data.

Kinematic-gravity model of geodynamo
Геофизический журнал, 2013 Based on the results of solving the inverse problem of magnetometry and analysis of some known models of the Earth magnetic field generation a model is proposed in which the current producing magnetic field is the vortex motion of positively charged ...

String-Generated Gravity Models [PDF]
Physical Review Letters, 1985 Expansion of supersymmetric string theory suggests that the leading quadratic curvature correction to the Einstein action is the Gauss-Bonnet invariant. We show that this model has both flat and anti-de Sitter space as solutions, but that the cosmological branch is unstable, because the graviton becomes a ghost there: The theory solves its own ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains
FEBS Open Bio, EarlyView.The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

SDUST2023GRA_MSS: the new global marine gravity anomaly model determined from mean sea surface model
Scientific DataThe global marine gravity anomalies are primarily recovered from geoid gradients in the along-track directions obtained through satellite altimetry. However, the accuracy of the gravity model is significantly constrained by the sparse geoid gradients in ...
