Graph-based transforms have been shown to be powerful tools for image compression. However, ... The approach relies on a separable spatio-angular transform and derives low frequency spatio-angular ...

The angular frequency-dependence suggests that a cell’s ability to sense the changing gravity vector is governed by the rate of perturbation. ... whereas faster clinorotation (lower graph) ...

Here, we realize angular multiplexing switchable nanoprinting functionality with independent amplitude encryption based on visible-frequency metasurfaces. By screening a large number of structural ...
