  • Patent number: 11944910
    Abstract: A system and method for providing virtual items to users of an online game operated in a virtual space. Multiple users may participate in affiliations or alliances of discrete groups of users in an online game and may access the online game through client computing platforms associated with the users. The affiliations may have affiliation game units associated with affiliations which provide a benefit to the members of the online game. Affiliation members may cumulatively obtain affiliation game units and/or upgrade affiliation game units by providing one or more virtual items. Upgrading affiliation game units may require the cooperation of multiple members of the affiliation.

  • Publication number: 20240015006
    Abstract: A hashing system (e.g., including a message expander) receives word data associated with a message. The hashing system identifies a plurality of message expansion computations that are configured to use the word data to generate a hash for the message. The hashing system pre-computes at least one message expansion computation of the plurality of message expansion computations using the word data to generate at least one constant. The hashing system executes a modified plurality of message expansion computations to generate the hash of the message. Executing the modified plurality of message expansion computations includes replacing the at least one message expansion computation of the plurality of message expansion computations with the at least one constant.

  • Publication number: 20230295741
    Abstract: Aspects of the present disclosure includes methods to quantify methylation in a DNA sample, where the method includes treating the sample to encode the presence or absence of DNA methylation, adding to the sample a set of synthetic molecules e.g., quality control template (QCT) molecules), generating a co-amplification mixture, sequencing the co-amplification mixture, determining a number of methylated molecules in the sample based on the number of methylated reads from the sample and a number of reads from the set of synthetic molecules.
