  • Patent number: 12102993
    Abstract: Methods for fabricating thermally stable reducible metal oxide catalyst support structures on a base material using a multi-step incipient wetness impregnation (IWI) process are disclosed. For example, reducible metal oxide catalyst support structures having high surface area and high thermal stability may be formed using a multi-step IWI process, where the support structure is generated through high-temperature calcination between IWI steps. The metal or metal oxide catalysts fabricated using the methods are also disclosed. The generation of engineered surface defects on reducible metal oxides using a gas reduction process to serve as anchoring sites for metal or metal oxide catalysts is also disclosed. Generating engineered defects through a gas reduction process may be a relatively low-cost and scalable process suitable for fabricating efficient catalysts using a wide range of materials.

    Abstract: The disclosed embodiments provide a system for performing unified management of targeting attributes in A/B tests. During operation, the system obtains attribute configurations for attributes to be used in subsequent targeting of users by A/B tests. Next, the system configures, based on the attribute configurations, onboarding of the attributes from an offline environment, a near-real-time environment, and an online environment. During an A/B test, the system retrieves values of one or more of the attributes for a user from locations specified in the attribute configurations. Finally, the system outputs the values with targeting conditions for the A/B test for use in selecting a treatment assignment for the user in the A/B test.

  • Publication number: 20190095828
    Abstract: The disclosed embodiments provide a system for managing an A/B test. During operation, the system calculates a first risk associated with ramping up exposure to a first A/B test by a first ramp amount. Next, the system uses a first sequential hypothesis test to compare the first risk with a first risk tolerance for the first A/B test. When the first sequential hypothesis test indicates that the first risk is within the first risk tolerance, the system automatically triggers a ramp-up of exposure to the first A/B test by the first ramp amount.
