Spatial omics technologies decipher functional components of complex organs at cellular and subcellular resolutions. We introduce Spatial Graph Fourier Transform (SpaGFT) and apply graph signal ...
The Fourier transform (FT) is a fundamental technique for analysing signals that are generally dependent on time or space, although any other parameters are possible. It transforms a signal from the ...
In this article we will study the spectral properties of a deterministic signal exponentially damped in the past and in the future (the damping in the future is controlled by a time constant). The ...
