  • Patent number: 12174830
    Abstract: Computer technology for use in a computer system including a database system including a database management sub-system, a primary database and a secondary database, with the secondary database being maintained at least approximately in synchronization with the primary database over time as changes are made to data of the primary database (for example, a database system that includes disaster recovery (DR) features). A statistics update is performed first on a standby database to determine whether query efficiency and/or query optimization really will be substantially improved by performance of the statistics update. If not, then statistics update on the primary database is postponed until a future time.

  • Patent number: 12117998
    Abstract: Machine-learning-based, adaptive updating of quantitative data in a database system is provided, which includes training one or more machine learning models to facilitate adaptively updating quantitative data in the database system, and ascertaining an update urgency index for updating the quantitative data for one or more data structures of the database system. The update urgency index is representative of an urgency for updating the quantitative data for the data structure(s) and is based, at least in part, on real-time query metrics. The machine learning model(s) is used to adaptively update the quantitative data, where the adaptively updating is based, at least in part, on the ascertained update urgency index. Processing of a database query is optimized in the database system using the adaptively updated quantitative data.

  • Publication number: 20240263097
    Abstract: A lubricating oil friction modifier and a preparation method therefor and use thereof are provided. The lubricating oil friction modifier has a chemical formula of AxBy+(C?)y. In the formula, A is a perfluoropolyether acyl group, By+ represents a cationic group having x amino groups and y ammonium ions, C? is BF4?, PF6?, AsF6?, FAP?, TFSI?, Mn2O4 or ClO4?, x is an integer greater than or equal to 1, y is an integer greater than or equal to 1, and x+y?2. The lubricating oil friction modifier has a good solubility with fluorine oil and fluorine grease, will not precipitate in the fluorine oil and the fluorine grease after being added, and can significantly improve the wear resistance of a lubricating oil such as the fluorine oil and the fluorine grease.

  • Publication number: 20240107398
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more threshold criteria are satisfied, wherein the one or more threshold criteria include at least one of a first value for an uplink grant rate, a second value for a buffer size, or a third value for a packet data convergence protocol discard rate, wherein the one or more threshold criteria relate to a network condition with less than a reference uplink throughput and greater than a reference downlink throughput. The UE may transmit information identifying one or more adjusted measurement values based at least in part on the determination of the one or more threshold criteria. Numerous other aspects are described.

  • Patent number: 8196106
    Abstract: Real-time statistical analysis is used to perform autonomic self-healing within the context of a 3-tier regression system for analysis of a computer system design component. Throughout the system, there are mechanisms for implementing self-healing if breakage is detected. The regression layer with the highest throughput is maintained in a much cleaner state than otherwise, thereby creating a more efficient environment for identifying and removing defects in the design.

  • Patent number: 6372239
    Abstract: Compositions and methods are provided for killing and controlling pests by using cocktails of plant alkaloids. In one embodiment, the pesticidal composition comprises: anabasine; and one or more plant alkaloids selected from the group consisting of toosendanin, azadirachtin, tomatine, nicotine, matrine, oxymatrine, sophocarpine, N-oxysophocarpine, cytisine, and aloperine. The pesticide can be used to protect crop plants, wood structures and animals from damages by harmful pests, overcome resistance of pests to current commercial pesticides, and reduce contamination to the environment.
