The present invention relates to an intracellular viral vector delivery method employing an iron ionviral vector composite. Techniques are described to modify such a display device to have the scanning capability and define a scanning region, where only the part of a scanning object falling into the scanning region is scanned. The circuit further includes a trace printed on the member, where the trace includes at least a longitudinal segment extending generally along at least a portion of the longitudinal axis and a transverse segment extending generally transverse to the longitudinal axis. The de-interleaver re-arranges the iterative decoded data samples in accordance with an inverse of the interleaver function before passing the decoded data samples to, for example, a second channel detector. The method further includes executing an Nth page programming operation, using the ISPP method, to program an Nth data page in the MLC memory cells. Each time the sampling point advances, the method detects which vertex and which face on a structural element the point of analysis is nearest.
