An apparatus is described to provide multi-channel bulk optical power detection. The sequence-dependent immunostimulatory RNA motifs and the polymers incorporating such motifs are potent and selective inducers of TLR7 and the TLR7-associated cytokine IFN-\u03b1. Once the deduplication procedure has been completed, the active file system of the storage system has been deduplicated, however, the target PCPI remains un-deduplicated. Additionally, the isolator system includes refresh timers and watchdog mechanisms to support persistent operation but manage possible communication errors that can arise between the isolated circuit systems.
