摘要:
A method and system for specifically detecting perfectly matched probe-target hybrids by annealing a hairpin-based probe to a nucleic acid target under conditions favoring the formation of perfectly matched targets over mismatched targets, and electrochemically detecting the annealed probe. Sensitivity of detection can be enhanced by catalyzed reporter deposition of probe signal prior to electrochemical detection. Specificity can be enhanced by including hairpin-based competitor probes in the annealing step. The detection assay is particularly applicable to typing single nucleotide polymorphisms by DNA sandwich hybridization.

As uses of interne based social networks have become broader, the potential for collaborative interaction has remained restricted by the effectiveness of voting methods. The application of cross-inhibitive-voting in social networks enables improved quality in the outcome of voting processes, and inclusion of greater numbers of voters by employing repetitive voting, quorum detection, reciprocal-time-weighting of votes, and the determination of a single best-of-N, or top-x-of-N ranking of alternatives determined by the number of in-favor votes minus the number of in-opposition votes.
