The two-way parabolic wave equation and reverberation from boundaries. [PDF]
The parabolic equation (PE) method has been generalized to handle backscattered energy with the single-scattering approximation. As with the two-way coupled mode method, range-dependent environments are approximated by a sequence of range-independent regions.

The current study deals with exact soliton solutions for Schrödinger-Hirota (SH) equation via two modified integration methods. Those methods are known as the improved (G′/G)-expansion method and the Kudryashov method. This model is a generalized version

Gravitational path integral from the T 2 deformation
We study a T 2 deformation of large N conformal field theories, a higher dimensional generalization of the T T ¯ $$ T\overline{T} $$ deformation. The deformed partition function satisfies a flow equation of the diffusion type.

Propagator and wave-equation inversion for near-receiver material properties [PDF]
Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections.
