The present invention relates to a novel human K ion channel, to nucleic acid molecules encoding the same and to vectors comprising said nucleic acid molecules. Phase errors which otherwise occur when performing non-Cartesian scans are either prospectively reduced by offsetting the timing error or retrospectively offset by applying phase corrections to the acquired image data. Thereafter, the plurality of pieces of the first liner are removed from the plurality of pieces of the multilayer optical film while the pieces of multilayer optical film are supported by the second liner. The method may further include correlating the first and second messages in response to a match between the first and second identifiers. The compensation current and the equivalent capacitor are used for determining a compensation voltage, and when the dimming signal is disabled, a closed loop within the capacitance amplifying module is changed to an open loop to keep the compensation voltage at a fixed value. The method includes calculating a verification score that is based on the check scores.
