Radio protocol for a next generation mobile communication system is disclosed including a radio link control layer for connecting to an upper layer through a service access point provided in advance and for connecting to a lower layer through a plurality of logic channels provided in advance. The planar films and substrates are: {1011} gallium nitride grown on a {100} spinel substrate miscut in specific directions, {1013} gallium nitride grown on a {110} spinel substrate, {1122} gallium nitride grown on a {1100} sapphire substrate, and {1013} gallium nitride grown on a {1100} sapphire substrate. The invention also relates to antibodies directed against these polypeptides and methods and kits for diagnosing viral infection. It is applicable to an industrial cracking process. The hybrid catalysts used in this invention comprise double metal cyanide complex catalysts and at least one co-catalyst.
