Sparse Code Shrinkage: Denoising of NonGaussian data by MLE

Trace concentrations of oil are measured by mixing the sample with an emulsifier to distribute the oil uniformly throughout the sample, transferring a measured portion of the emulsified sample to a reservoir of a bottle having a capillary neck, equilibrating the temperature of the sample portion to over 135 DEG F, adding a demulsifier to the bottle, while keeping the liquid level therein below the neck, whirling the bottle in a heated centrifuge to separate out the oil, adding liquid to the bottle to raise the liquid level to form a column of separated oil wholly within the neck, equilibrating the temperature of the contents of the bottle, and measuring the length of the column of oil.
