  • Patent number: 10289710
    Abstract: Embodiments of the present invention provide a method for modifying a root node, and a modification apparatus. The method for modifying a root node of the present invention includes: receiving a root node modification request; modifying a root node in a data area of a database according to the modification information; replicating the modified root node to the general area of the database; finding, in the general area of the database, that an identifier of an active mapping page is the identifier of the first mapping page, and determining that the first mapping page is the active mapping page; and replacing the second mapping page with the modified root node according to the modified root node that is replicated to the general area, and modifying the identifier of the active mapping page to the identifier of the second mapping page. The present invention improves concurrent processing efficiency of indexing.

  • Patent number: 9157112
    Abstract: Nucleic acid detection probes that comprise a pair of complementary, fluorophore/quencher labeled oligonucleotides, one of which is shorter than the other, are able to detect single-stranded and double-stranded targets in hybridization reactions and amplification reactions with real-time detection. Double-stranded probes of equal length are useful in PCR amplification reactions with real-time detection.

  • Patent number: 7799522
    Abstract: Double-stranded nucleic acid hybridization probes comprise a longer strand perfectly complementary to a preselected target sequence in an assay and a shorter second strand complementary to the longer strand. The strands are labeled with interactive labels such as a fluorophore and a quencher. The probes may be used in real-time amplification assays to distinguish among alleles.
