A data slicing circuit that receives a demodulated signal including a known data pattern followed by unknown data generates at least two different threshold potentials intermediate between the peak and bottom levels of the demodulated signal. Sensor quantity and location is optimized for maximum sensitivity to known process variations. The compounds specified are tetra-cyclic derivatives and have been shown to be antiproliferative against human estrogen-dependent cancer cells and to have good binding affinity for the estrogen receptor. A spatial differentiator in a block distortion evaluator makes a spatial derivative calculation of the original image data, and a spatial differentiator makes a spatial derivative calculation of the decoded image. Trucks are located within the mounting tracks to move therein. The second interconnect device is capable of routing the first data set to the destination.
