Abstract: The disclosed embodiments include computer-implemented processes that, using a distributed notarized ledger, constrain an ability of multiple parties to simultaneously, or near simultaneously, update or modify elements of reference data maintained within a centralized data store. For example, an apparatus may receive, from a first computing system, a request to modify reference data maintained at a second computing system. The apparatus may approve the first requested modification to the reference data based on a notarization criterion maintained within an element of a notarized distributed ledger, and perform operations that record notarization data characterizing the approved modification within an additional element of the notarized distributed ledger. The apparatus may also transmit the notarization data to the first computing system, and the notarization data causing an application program executed by the first computing system to modify local reference data in accordance with the notarization data.

Abstract: Systems and methods for identifying one or more master tables of a datalake are described. A system may obtain a plurality of computer readable tables of a datalake (with each computer readable table including one or more features). The system may also group the plurality of computer readable tables into a plurality of groups based on a number of features of each computer readable table of the plurality of computer readable tables. The system may further generate, for each of one or more groups of the plurality of groups, one or more neighborhoods based on a similarity of features between computer readable tables of the group. The system may also identify, for each neighborhood, one or more master tables from the one or more computer readable tables of the group. The system may further provide an indication of one or more master tables identified in the datalake.

Abstract: The present invention provides a novel beta glucosidase and a process for extraction of a beta-glucosidase from Rauvolfia serpentine useful for the cleaving of beta-1,4 linkage of PNPG and to convert other gluco-conjugates such as strictosidine and raucaffricine into their corresponding aglycon such as vomilenine, commercially through immobilizing the enzyme. The ? glucosidase enzyme has shown maximum activity in the acid pH range, with high optimum temperature using PNPG as substrate. The crude enzyme, when stored at 4° C., was quite stable for 6 days with 50% loss of activity. The enzyme was activated in presence of FeSO4 in the assay mixture.
