  • Patent number: 11825788
    Abstract: A method for promoting the accumulation of secondary metabolites of cannabis is disclosed. The method comprises the step of adding an irradiation of green-yellow light, which has a peak wavelength at 505-590 nm, into the indoor growing environment of cannabis to improve the level of cannabidiol (CBD), secondary metabolites in cannabis. While maintaining the light intensity and other growth conditions, the yield and/or level of CBD, secondary metabolites in cannabis, can be increased by up to 11.04%.

  • Publication number: 20230104005
    Abstract: A catalyst may include a base material, a precious metal, and a metal oxide. At least a portion of the precious metal may form catalytically active sites on a surface of the metal oxide. The catalytically active sites may be formed by depositing the precious metal on the base material to form a catalyst structure, performing a first calcination on the catalyst structure, depositing the metal oxide on the catalyst structure, wherein the precious metal is at least partially encapsulated by the metal oxide, performing a second calcination on the catalyst structure, and reducing the catalyst structure with a reductive material, where at least a portion of the precious metal diffuses to a surface of the metal oxide to form the catalytically active sites.

  • Publication number: 20220347668
    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.

  • Publication number: 20200104398
    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.
