An image sequence captured at a first image rate is encoded as an encoded image sequence at a second image rate with information in the encoded image sequence indicative of images that are repeated when decoded. In accordance with some embodiments, a semiconductor memory has an array of non-volatile memory cells, and a control circuit which stores a first write command from a host to write data to said array. This relationship is used to establish the optical pathlength for samples containing an unknown concentration of analyte but having similar solvent composition. This invention further relates to the inbred and hybrid genetic complements of the inbred corn plant 89AHD12, and also to the SSR and genetic isozyme typing profiles of inbred corn plant 89AHD12.
