Nine-quadrant diagram analysis showed that 95, 335, 116, 494, 12220, 486, 110, 334, and 158 genes were distributed in quadrants 1-9, respectively (Figure 2E). Further analysis revealed no correlation ...

A four-quadrant current multiplier circuit is presented. It is based on the current-mode approach and the square-law characteristics of a MOS transistor in saturation. The analog multiplier is ...
