A computer readable medium encoded with computer readable code that includes a variant behavior object that includes a behavior code unit implemented in computer readable code, wherein the variant behavior object is associated with behavior code that effects a pattern for processing of a data set and that references another behavior object. Also disclosed are RNA vector replicons, alphavirus vector constructs, and eukaryotic layered vector initiation systems which contain the above-identified nucleic acid molecules. Information having an identifier is received at a first protocol layer from a higher protocol layer in the protocol stack. A steeply inclined surface step of detecting a steeply inclined surface in the shape of the protruding object is performed.
