The SDUST2022GRA global marine gravity anomalies recovered from radar and laser altimeter data: contribution of ICESat-2 laser altimetry [PDF]
Earth System Science DataThe global marine gravity anomaly model is predominantly recovered from along-track radar altimeter data. Despite significant advances in gravity anomaly recovery, the improvement of the gravity anomaly model remains constrained by the absence of cross ...

Predicting Performance of Hall Effect Ion Source Using Machine Learning
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

Mitigating errors in marine gravity recovery induced by sea level variability in SWOT observations
International Journal of Applied Earth Observations and GeoinformationThe Surface Water and Ocean Topography (SWOT) mission has significantly advanced marine gravity recovery, yet its wide-swath measurements reveal the effects of strong sea level variability, emphasizing the need for effective correction methods.

On Adler-Bell-Jackiw Anomaly in 3-brane Scenario
, 2002 We investigate the ABJ anomaly in the framework of an effective field theory for a 3-brane scenario and show that the contribution from induced gravity on the brane depends on both the topological structure of the bulk space-time and the embedding of the

Anomalies of the Vertical Gradient of Gravity Associated with Anomalies of Gravity.
Journal of Physics of the Earth, 1952 The gravity anomaly is necessarily associated with the anomaly of the vertical gradient of gravity. The relation between the two kinds of anomaly has been invest gated. The anomaly of the vertical gradient is sometimes too large to be neglected in the free air reduction of gravity.

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

Quantum irreversibility in arbitrary dimension [PDF]
, 1999 Some recent ideas are generalized from four dimensions to the general dimension n. In quantum field theory, two terms of the trace anomaly in external gravity, the Euler density G_n and Box^{n/2-1}R, are relevant to the problem of quantum irreversibility.
