  • Publication number: 20240296909
    Abstract: A method of the present invention includes: performing clustering on a sample sequence, the clustering including the following: grouping base sequences having 100% similarity with each other, for the sample sequences thereby to generate a primary OTU (Operational Taxonomic Unit); and further performing the clustering on the sample sequences thereby to generate a secondary OTU composed of a sequence of a predetermined centroid, and sample sequences that have a similarity larger than or equal to a predetermined threshold value with the sequence of the centroid. Here, the predetermined threshold value is less than 100%. The method further includes: setting a sequence of a primary OTU having the largest number of sequences among the primary OTUs included in each secondary OTU, as a representative sequence of the secondary OUT; collating the representative sequence with a database; and thereby estimating a lineage of the secondary OTU.

  • Patent number: 6574150
    Abstract: A low power consumption type dynamic random access memory (DRAM) operable with reduced current consumption responsive to an external signal, without causing occurrence of malfunction during low current consumption. An input circuit for receiving signals, a memory array for holding data, and a peripheral circuit for controlling the memory array are driven by an internal voltage supplied by two groups of internal voltage receiving circuits, while an output circuit for outputting signals is driven by an external power supply. The two groups of internal voltage receiving circuits are deactivated in response to an externally provided power supply control signal, and the output circuit is controlled so as to be in a high impedance condition with voltage of the external power supply being applied thereto.
