In this paper we show thatusing Discrete Prolate SpheroidalSequences, rather than sine functions, it is possible to derive a sampling andreconstruction methodwhich is similar to CS.

Assuming non-uniform sampling our procedure can be connected with compressive sensing without complex reconstruction methods.

Dissociating neuronal gamma-band activity from cranial and ocular muscle activity in EEG

(seems like they are trying to reduce the amount of "noise" using PSWF, focusing in on the EEG nodes by only capturing the wave function of the human head???? is this right ?)

If the prolate spheroid is a better and more accurate model of the human head and the wave-function of a prolate spheroid is being sought/ used, is the wave-function of a brain then being utilized with this "medical" technology ?

Could this be a method of data acquisition for mind uploading/ brain mapping ?

The focus of mind uploading, in the case of copy-and-transfer, is ondata acquisition

Spheroidal Wave Functions

is data acquisition the reason they are using the wave-function of a prolate spheroid ?

because..

The result of every possible measurement on a quantum system is coded in its wave function,

& Might it be possible to combine the PSWF method withthiswave-function measurement method ?

The new method, calledcompressive direct measurement,allowed the team toreconstructa quantum state at 90 percent fidelity(a measure of accuracy) using only a quarter of the measurements required by previous methods.

both DO seem to deal with data acquisition and reconstruction techniques....

AND.. both "COMPRESSIVE DIRECT MEASUREMENT" and "COMPRESSIVE SENSING" are used...
