  • Patent number: 11960459
    Abstract: Systems and methods are described for merging customer profiles, such as may be implemented by a computer-implemented contact center service. In some aspects, a subset of profiles may be determined that satisfy merging criteria, where individual profiles include a plurality of data fields. At least one value in a first data field that conflicts between at least two profiles may be identified. Next a merged value may be selected for the first data field based on data deduplication criteria, where the data deduplication criteria includes at least one indicator of accuracy of values of the plurality of data fields. As a result of a determination that at least the subset of profiles of the group of profiles meet the merging criteria, at least the subset of profiles may be combined into a combined profile using the merged value.

  • Publication number: 20240052037
    Abstract: The present invention provides an anti-PD-L1/anti-CD47 bispecific antibody and a preparation method therefor. The antibody has characteristics of a natural IgG, and is a highly stable heterodimeric form without heavy and light chain mismatching. The bispecific antibody can bind two target molecules at the same time and has a smaller side effect.

  • Publication number: 20240034801
    Abstract: Provided are an anti-PD-L1/anti-4-1BB natural antibody structure-like heterodimeric form bispecific antibody and a preparation thereof. Specifically, provided are an anti-PD-L1/anti-4-1BB bispecific antibody that has natural IgG features, that has no mismatch between heavy and light chains and that is in the form of a highly stable heterodimer, as well as a preparation method therefor. The bispecific antibody can simultaneously bind two target molecules and is more effective in treating complex diseases and has fewer side effects.

  • Publication number: 20220327128
    Abstract: A method for querying in a candidate vector set candidate vectors similar to object vectors is disclosed, wherein the candidate vector set comprises a plurality of candidate vectors each being quantized as having a central vector portion and a residual vector portion, and the candidate vector set comprises a plurality of candidate vector subsets, the method comprising: acquiring a set of object vectors; querying, for each object vector of the set of object vectors, a first number of candidate vector subsets that are closest to the object vector; generating and storing a plurality of common calculation results based on a set of central vector portions and a set of residual vector portions of candidate vectors of the first number of candidate vector subsets; generating and storing pre-calculation results based on the set of object vectors and the set of residual vector portion; and determining, for each object vector of the set of object vectors, a second number of candidate vectors that are similar to the obje

  • Patent number: 7045477
    Abstract: A process for continuously regenerating catalyst particles comprising: passing deactivated catalyst particles downwards in sequence through the first coke-burning zone, second coke-burning zone, oxychlorination zone, and calcination zone in the regenerator, wherein the catalyst particles are contacted with the regeneration gas from the second coke-burning zone, the supplemented dry air, and an inert gas in the first coke-burning zone; introducing an oxygen-containing regeneration gas from the second coke-burning zone into the regenerator, wherein said gas is contacted with the catalyst particles from the first coke burning zone; withdrawing the regeneration gas from the regenerator through the first coke-burning zone and, after the recovery system, recycling it to the second coke-burning zone. The regeneration gas may pass the catalyst bed in either a centrifugal or centripetal way.
