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 ...

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

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) ...
