  • Publication number: 20220213464
    Abstract: A hierarchical catalyst composition comprising a continuous or particulate macroporous scaffold in which is incorporated mesoporous aggregates of magnetic nanoparticles, wherein an enzyme is embedded in mesopores of the mesoporous aggregates of magnetic nanoparticles. Methods for synthesizing the hierarchical catalyst composition are also described. Also described are processes that use the recoverable hierarchical catalyst composition for depolymerizing lignin, remediation of water contaminated with aromatic substances, polymerizing monomers by a free-radical mechanism, epoxidation of alkenes, halogenation of phenols, inhibiting growth and function of microorganisms in a solution, and carbon dioxide conversion to methanol.

  • Publication number: 20210224750
    Abstract: The disclosed embodiments provide a system for performing quality-based scoring. During operation, the system determines, based on data retrieved from a data store in an online system, features related to a completeness of attributes in an opportunity posted in the online system and a source of the opportunity. Next, the system performs one or more operations that apply a first machine learning model to the features to generate a quality score representing a prediction of user engagement with the opportunity. The system then adjusts calculation of a relevance score representing a likelihood of a positive outcome between a user and the opportunity based on the quality score. Finally, the system modifies content outputted in a user interface of the online system based on the adjusted calculation of the relevance score.

  • Publication number: 20200136818
    Abstract: A system may include registration devices configured to generate, in a trusted environment, respective fully homomorphic encryption (FHE) biometric image registration records for first users. A registration data storage device may, in a non-trusted environment, store the FHE biometric image registration records and associated service context data. Capture devices may, in a less-trusted environment, generate respective FHE biometric image recognition records for second users at least partially overlapping the first users. A recognition data storage device may, in a non-trusted environment, store the FHE biometric image recognition records, and a recognition device, in a non-trusted environment, calculates encrypted distances between each FHE biometric image recognition and registration records, and retrieves respective service context data based upon the encrypted distances.

  • Publication number: 20200007634
    Abstract: A historical online user behavior-based approach is used to make a recommendation of a cross-online service vertical entity for a primary online service vertical entity with which a user is currently interacting online. The recommendation is made based on the similarity of historical online user behavior between the vertical entities. To do this, historical online user behavior of each of the vertical entities is represented as a respective vector. Each dimension of a vector represents a historical level of interaction between a separate user or a separate group of related users and the vertical entity represented by the vector. A similarity measure is used to measure the similarity between the vectors for the vertical entities. The recommendation of the cross-online service vertical entity is then made for the primary online service vertical entity based on the extent of the similarity between the vectors according to a similarity measure.
