Recombinant VSV viral particles and the use thereof as vaccines for immunization are described. The ECGI proteins and nucleic acid sequence encoding them are useful in the diagnosis and treatment of epithelial cell cancers, for example prostate, ovarian, colon cancer, and the like. The digital signal processor may be located at a ground station to which communication is made via a telemetry link. Each of the plurality of representative samples has a plurality of dynamic instructions, wherein dynamic instructions from the plurality of representative samples represents only a subset of a stream of dynamic instructions generated when the application program is executed against the input dataset. According to the invention, the element comprises a metallized sheet disposed between said set of layers and said protective sleeve, together with a moisture-absorbing swelling layer disposed between said set of layers and said metallized sheet. A layer may cause some of the processing of a request to be handled by another service.
