In signal processing, white noiseis a random signal with a flat (constant) power spectral density. In otherwords, it is a signal that contains equal power within any frequency band witha fixed width.The parameter μ in this formula is the mean orexpectation of the distribution (and also its median a...

Traditional single particle reconstruction methods use either the Fourier or the delta function basis to represent the particle density map. We propose a more flexible algorithm that adaptively chooses the basis based on the data. Because the basis adapts to the data, the reconstructi...
