Methods for pre-processing video sequences prior to compression to provide data reduction of the video sequence. First, a semiconductor wafer that includes a semiconductor layer and a semiconductor element layer, which is located on the semiconductor layer, is formed. Accordingly, such compositions have use in the treatment and prevention of malaria. On both upper and lower surfaces of the circuit base, a first and a second semiconductor chip are mounted. A data-signal bus interconnects the unpowered and powered sockets.
