Using symbolic regression to discover physical laws from observed data is an emerging
field. In previous work, we combined genetic algorithm (GA) and machine learning to …

Acoustic transversely isotropic (TI) media are defined by artificially setting the shear-wave
velocity in the direction of symmetry axis, VS 0, to zero. Contrary to conventional wisdom that …

Reverse time migration (RTM) in complex anisotropic media requires calculation of the
propagation of a single-mode wave, the quasi-P-wave. This was conventionally realized by …

Computation of first-arrival traveltimes for quasi-P waves in the presence of anisotropy is
important for high-end near-surface modeling, microseismic-source localization, and …

An orthorhombic velocity model covers anisotropy and vertical/horizontal heterogeneity in
the uniform 3D framework. It is important to define the azimuthal dependence of kinematic …

Two second-order wave equations for acoustic vertical transversely isotropic (VTI) media are
transformed to six first-order coupled partial differential equations for a more straighforward …

The resolution of a multiparameter full-waveform inversion (FWI) is highly influenced by the
parameterization used in the inversion algorithm, as well as the data quality and the …

Wavefield extrapolation in pseudoacoustic orthorhombic anisotropic media suffers from
wave-mode coupling and stability limitations in the parameter range. We use the dispersion …

Seismic-wave attenuation is an important component of describing wave propagation.
Certain regions, such as gas clouds inside the earth, exert highly localized attenuation. In …

Anelliptic approximations for phase and group velocities of qP waves in transversely
isotropic (TI) media have been widely applied in various seismic data processing and …
