Methods for genotyping polymorphisms using allele specific probes are disclosed. The assembly prevents relative rotation and substantially reduces eccentricity between a cutting tool and a tool holder. Addressing electrodes on an underlying metallization layer and addressing electrodes at the yoke level provide electrostatic forces that cause the mirrors to tilt and then to return to their flat state. The system may further include a voltage measuring device configured to detect a change in voltage at a terminal of the at least one capacitor in response to the selective coupling of the at least one capacitor to the second resistance. At least one of the heating or retaining parts has a first permanent magnet cooperating with a second, opposing permanent magnet belonging to its housing, the second permanent magnet being mounted in phase with the first. In addition, CBC structure may also include a MIM capacitor structure coupled to the MOM capacitor structure.
