Investigating Alfvénic wave propagation in coronal open-field regions
Nature Communications, 2015 The physical mechanisms behind accelerating solar and stellar winds are a long-standing astrophysical mystery, although recent breakthroughs have come from models invoking the turbulent dissipation of Alfvén waves.

Physics‐Informed Neural Networks (PINNs) for Wave Propagation and Full Waveform Inversions [PDF]
Journal of Geophysical Research: Solid Earth, 2021 We propose a new approach to the solution of the wave propagation and full waveform inversions (FWIs) based on a recent advance in deep learning called physics‐informed neural networks (PINNs).

Wave Propagation in Granular Materials [PDF]
, 2005 Wave propagation is a fundamental property of all physical systems. The wave speed is directly related to the compressibility of the system and determines the rate at which local disturbances are propagated into the bulk of the material.

Wave Propagation of Porous Nanoshells [PDF]
Nanomaterials, 2018 This study aims at investigating the wave propagation of porous nanoshells. The Bi-Helmholtz non-local strain gradient theory is employed in conjunction with a higher-order shear deformation shell theory, in order to include the size-dependent effects.

Generation of equations for shell models of turbulence in the Maple system [PDF]
EPJ Web of Conferences, 2021 The paper describes a technology for the automated compilation of equations for shell models of turbulence in the computer algebra system Maple. A general form of equations for the coefficients of nonlinear interactions is given, which will ensure that ...

Operative center of the geophysical prognosis in Izmiran [PDF]
Annales Geophysicae, 2005 IZMIRAN was founded about 65 years ago with one of the goals of carrying out geomagnetic prognoses. More or less, this activity has been developed during its entire history, but about 6 years ago this aim became sufficiently feasible due to the ...
