A method for determining the type of a digital versatile disc so that a DVD+ can be distinguished from a DVD\u2212. Also disclosed are methods for utilizing SIP-1 polypeptides and polynucleotides in diagnostic assays. The IO circuit provides a data path between the IO pins and the resident IC. The legs of the interconnect assembly extend from the passage on an end of the jacket, where the legs are continuations of or extensions from the sub-units such that the optical fibers further extend through the legs. The extensible apertured nonwoven web produced has a plurality of apertures each having a hole size greater than 2 mm2, and a hole aspect ratio less than 6, the nonwoven web having an open area greater than 15% and being capable of at least 70% extension in the cross machine direction at a loading of 10 gcm.
