An autotesting method of a cells matrix of a memory device includes the steps of reading the values contained in a plurality of the memory cells, comparing the read values with reference values, signaling mismatch of the read values with the reference values as an error situation, and storing the error situations. Shifting can be carried out with a low-output drive, particularly in the parked shifting position \u201cP\u201d, also when very large forces are required such as those occurring when the vehicle is parked on a hill. Power supply to the dimming control section is performed by an insulated auxiliary power supply. Some electrochemical cells may also further comprise a contact member in between the first container and the second container. Methods for regulating the expression of a gene encoding a protein isoform characterized as an apparent target of NMD comprise biasing expression of the isoform by modulating transcript splicing or modulating NMD activity. This is accomplished by means of an operational amplifier which compares the common mode voltage of the second differential drive circuit to a reference voltage.
