The present invention relates to a first group of novel genes, here identified as genomic address messenger or GAM genes, and a second group of novel operon-like genes, here identified as genomic record or GR genes. Each arm has a supporting surface pointing outside and configured to contact an adjacent vertebral body, a groove pointing inside and extending along a transverse direction, and a channel pointing inside and extending along a longitudinal direction. The memory cell comprises MOS transistors whose gate electrodes are connected with a word line. The violation recording unit determines a violation recording resource allocation schedule. Upwardly inclined guides are provided on the underside of the hull for upwardly guiding the skis out of the water onto the ice floating on the water as the vehicle exits the water and moves onto the ice.
