Abstract: A system and method for authenticating users of a data processing platform stores a mapping of a unique user platform identifier to multiple user identity provider identifiers associated with multiple realms for a same user. In some examples, the method includes receiving a request from a client device to establish an access session to perform one or more actions on data of the data processing platform and receiving, from at least one of the first external identity provider of the first realm or the second external identity provider of the second realm, a user identity provider identifier associated with the request. In certain examples, the method includes granting permission to perform the one or more actions on the data of the data processing platform based at least in part on the received user identity provider identifier.

Abstract: Glucose and ketones may be dysregulated singularly or concurrently in certain physiological conditions and may be advantageously assayed together using an analyte sensor capable of detecting both analytes. Certain analyte sensors capable of dual detection may comprise a first working electrode and a second working electrode, a ketones-responsive active area disposed upon a surface of the first working electrode, a glucose-responsive active area comprising a glucose-responsive enzyme disposed upon a surface of the second working electrode, a membrane having a first portion overcoating the ketones-responsive active area and a second portion overcoating the glucose-responsive active area, in which the first portion and the second portion have different compositions. The ketones-responsive active area comprises an enzyme system comprising at least two enzymes that are capable of acting in concert to facilitate detection of ketones.

Abstract: Systems and methods generate a first security node hash identifier by performing a first hash operation, such as a one-way hash, on a first data resource identifier associated with a first data resource, such as a data set, produced by a data resource platform. The systems and methods generate a dependent second security node hash identifier by performing a second hash operation on a second data resource identifier associated with a dependent second data resource produced by the data resource platform and on the first security node hash identifier, receive an access request for access to the dependent second data resource; and in response to the access request, grant permission to access the dependent second data resource to a user associated with the access request based on the dependent second security node hash identifier.

Abstract: An in vivo apparatus for determining activity of an enzyme including a reservoir, a predetermined quantity of a reactant contained with the reservoir, and a working electrode having at least one aperture. The reactant is configured to be released from the reservoir through the at least one aperture of the working electrode. The working electrode is configured to detect a product of a reaction of the reactant with an enzyme and produce a signal proportional to the activity of the enzyme.
