This paper investigates the time-space fractional diffusion equation with an absorption term. The Green's function of the time-space fractional diffusion equation obtained by using Fourier transform, ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Specifically, the diffusion model is first pretrained with unlabeled HSI patches to mine the connotation of unlabeled data, and then is used to extract the multi-timestep multi-stage diffusion ...
