Compounds having the formulaare apoptosis promoters. The method includes determining a data value from one of more than two data values to be stored in the memory cell, and applying a gate voltage to the control gate at one of a predetermined set of gate voltage levels selected in response to the determined data value. The screw shaft and a chassis holding a turntable are oscillated by a driving motor pivoting on the first connecting plate. The center of a largest such shape is mapped back into the units of the original eye diagram as optimum sampling parameters for data analysis equipment that uses the receiver to sample the signal once per unit interval to discover logical value.
