The nucleic acid detection system provided in this application includes a Cas protein, a first RNA portion, and a second RNA portion. The first and second RNA portions can interact to form a functional crRNA in the presence of the target nucleic acid. This functional crRNA can form a complex with the Cas protein and activate the trans-cleavage activity of the Cas protein. This invention creatively separates the crRNA into independent first and second RNA portions, whose binding affinity to Cas12a is significantly weaker than that of the full-length crRNA, thereby reducing the cis and trans-cleavage activity of Cas12a. This low-activity state provides a sufficient time window for the nucleic acid amplification reaction, allowing the amplification products to accumulate. When the target amplification product accumulates to a sufficient concentration, it can induce the separated crRNA to assemble with Cas12a into an active complex, thereby activating trans-cleavage and achieving an intelligent response of amplification-driven cleavage. The entire process requires no physical isolation, chemical inhibition, or programmed temperature control, truly achieving closed-tube, unmanned detection.

For scheduling background processes in a data storage system, feature data is continually collected for activity-indicating performance features over regular multi-hour sample periods, and collected feature data is provided to a model-based workload analyzer having (i) a features input layer employing weighted feature learning to generate a stream of feature vectors and (ii) a variational autoencoder (VAE) operable in response to the stream of feature vectors to generate a latent-space representation of the collected feature data having a normalized distribution. The latent-space representation is compared against a normalized threshold to identify periods of low activity, and based on the comparing the background processes are initiated during the identified periods of low activity.
