  • Patent number: 12223080
    Abstract: This disclosure describes a natural language question (NLQ) query service within a service provider network that provides row level security (RLS) for autocomplete during entry of NLQs and fuzzy matching in NLQ answering. The rules take the form of per-user predicates such as Tim can only see rows with region=US. In configurations a complex extraction and preprocessing pipeline to extract distinct combinations of values against RLS predicate “rule keys” is used. Those distinct values are indexed along with grouped rule keys to enable pushing down predicates at auto-complete time. This enables pushing part of RLS rule handling to ingestion time of a dataset rather than handling all RLS rule handling at query time, enabling meeting of latency goals. In configurations, a single logical document of unique cell values is split into multiple documents with a subset of rule keys to handle scalability limits.

  • Publication number: 20240226226
    Abstract: The present disclosure provides compositions, methods and kits for treatment of pruritus (itch) in an individual. The compositions, methods, and kits are for administering an implant comprising a kappa-opioid receptor agonist to an individual, where the implant comprises a sustained release composition comprising a kappa-opioid receptor agonist and a biocompatible polymeric matrix. Implantation of the device allows a controlled release of kappa-opioid receptor agonist for an extended period of time. The implant may be implanted subcutaneously in an individual in need of continuous treatment with a kappa-opioid receptor agonist for treatment and relief of pruritus.

  • Patent number: 11852701
    Abstract: A defect centre-based sensor is disclosed. The sensor comprises instrumentation which includes a generator for causing excitation in an active element, for example a diamond, and a detector for measuring a transition in the active element. The generator is an optical source and/or the detector is an optical detector. The sensor further comprises an optical waveguide and a sensor head in communication with the source and/or the detector via the optical waveguide. The sensor head houses the active element having at least one defect centre, for example, a nitrogen vacancy, responsive to an applied magnetic field, electric field or temperature and a signal delivery arrangement, for example at least one lens, arranged to optically couple the optical waveguide to the active element.
