In practice, replicating portfolios are seldom, if ever, "exact" replications. Humphrey counts them as implicit replications of PK experiments in which PK fails to appear. Within the California two-spot octopus genome there are substantial replications of two gene families. The story created "hundreds of identical Internet replications" according to Snopes. Bringing the replications into synchrony requires making their internal stored states the same. The outputs of the replications are compared using a voting circuit. Fewer than half of the attempted replications were successful. After many replications where the viral gene stays latent tumours begin to grow. Two replications of this result have been attempted. A machine with two replications of each element is termed dual modular redundant (DMR). A machine with three replications of each element is termed triple modular redundant (TMR). This model can be applied to any larger number of replications. At any time, all the replications of each element should be in the same state. The Collaborative Replications and Education project recruits undergraduate students as citizen scientists by offering funding.
