The present invention provides a simple and direct method for the simultaneous correction of steady-state polarized fluorescence intensities, depolarized by the effects of applied hydrostatic pressure without having to first determine the scrambling factors from a separate experiment. Given a document, summarization can be defined as picking k sentences from the original document D such that the constructed summary exhibits two key properties: coverage and orthogonality. The top frame includes a plurality of operatively associated ball screw assemblies that enable movement of the top frame with respect to a bottom frame of the leveler. The pair of pole elements and the at least one shunt element are formed from a material that consists essentially of ferrous metal having an overall carbon content of less than 0.
