The present invention relates to a method of qualifying ovarian cancer status in a subject comprising: measuring at least one biomarker in a sample from the subject and correlating the measurement with ovarian cancer status. Next, a resist mask selectively covering the rear surface of the n\u2212 semiconductor wafer is formed. The instant invention is also directed to a method for polymerizing at least one olefinic monomer comprising the step of contacting a feed containing the olefinic monomer under polymerization conditions with the transition metal-free catalyst composition.
