    “…We assess the value of machine learning as an accelerator for the parameterization schemes of operational weather forecasting systems, specifically the parameterization of nonorographic gravity wave drag. Emulators of this scheme can be trained to produce stable and accurate results up to seasonal forecasting timescales. …”

    “…In this paper, we investigated a new anisotropic solution for the strange star model in the context of [Formula: see text] Einstein-Gauss-Bonnet (EGB) gravity. For this purpose, we used a linear equation of state (EOS), in particular [Formula: see text] , (where [Formula: see text] and [Formula: see text] are constants) together with a well-behaved ansatz for gravitational potential, corresponding to a radial component of spacetime. …”

    “…CATEGORY: Ankle INTRODUCTION/PURPOSE: Diagnosis of mortise instability in the apparent isolated lateral malleolus fracture can be challenging and often relies on stress radiography. While the gravity stress view (GSV) is commonly utilized, it traditionally requires the patient to assume the lateral decubitus position for imaging of the ankle. …”

    “…A possible density contrast might have been discovered that could be consistent with the presence of water phase of potential terrestrial origin. Using novel gravity aspects (descriptors) derived from harmonic potential coefficients of gravity field of the Moon, we discovered gravity strike angle anomalies that point to water phase locations in the polar regions of the Moon. …”
