Quasi-P-Wave Reverse Time Migration in TTI Media with a Generalized Fractional Convolution Stencil
In seismic modeling and reverse time migration (RTM), incorporating anisotropy is crucial for accurate wavefield modeling and high-quality images. Due to the trade-off between computational cost and simulation accuracy, the pure quasi-P-wave equation has

Periodic solutions to a class of distributed delay differential equations via variational methods
In this article, we study the existence of periodic solutions to a class of distributed delay differential equations. We transform the search for periodic solutions with the special symmetry of a delay differential equation to the problem of finding ...

Partial Differential Equations-Based Iterative Denoising Algorithm for Movie Images
Film video noise can usually be defined as the error information visible on the video image, caused by the digital signal system. This distortion is inevitably present in the video obtained by various camera equipment.
