  • Publication number: 20240346270
    Abstract: Molecular anti-counterfeiting taggants are made from a plurality of synthetic polynucleotides that collectively encode a bit sequence using the sequences and hybridization states of the polynucleotides. The polynucleotide taggant is placed on an item as a molecular identifier of authenticity. The bit sequence encoded by the polynucleotide taggant is read out using a substrate which has bound polynucleotides complexes that hybridize with the synthetic polynucleotides in the polynucleotide taggant. A detectable signal is present where hybridization occurs. To prevent a bad actor from reverse engineering and creating a copy of the polynucleotide taggant using the results of hybridization to the substrate, multiple versions of the substrate are created. Each version hybridizes to different subsets of the synthetic polynucleotides in the polynucleotide taggant. A detectable pattern on the substrate that is present when exposed to the polynucleotide taggant is used for validating authenticity of the item.

  • Patent number: 12101887
    Abstract: In an embodiment, a method of manufacturing (100) is described. The method comprises providing (102) a first layer defining a first inner surface (203a) and a first outer surface (203b), a second layer defining a second inner surface (205a) and a second outer surface (205b), and an electrical component (206) positioned on the first inner surface or the second inner surface. The method further comprises attaching (104) the first and second layers together to create a device (200) comprising the first and second layers, wherein the first outer surface and the second outer surface define an external surface of the device. The device further comprises a sealed portion (208) defined by liquid-tight attachment between the first and second inner surfaces. In use of the device, the sealed portion prevents liquid ingress into the device between the first and second layers towards the electrical component.

  • Publication number: 20240304302
    Abstract: A system is provided that employs a machine learning (ML) decision tree to provide a treatment analysis for an arrhythmia. The ML decision tree includes decision nodes (non-leaf nodes) and treatment analysis nodes (leaf nodes). Each decision node corresponds to a feature derived from electronic health records and has branches corresponding to feature values. A treatment analysis node corresponds to a treatment analysis based on feature values of a path from the root node to that treatment analysis node. To provide a treatment analysis for a candidate, the system identifies a path from the root node to a treatment analysis node based on a candidate feature vector derived from an electronic health record of the candidate and outputs the treatment analysis of the treatment analysis node of the identified path.

  • Publication number: 20240265011
    Abstract: A multi-cluster computing system which includes a query result caching system is presented. The multi-cluster computing system may include a data processing service and client devices communicatively coupled over a network. The data processing service may include a control layer and a data layer. The control layer may be configured to receive and process requests from the client devices and manage resources in the data layer. The data layer may be configured to include instances of clusters of computing resources for executing jobs. The data layer may include a data storage system, which further includes a remote query result cache Store. The query result cache store may include a cloud storage query result cache which stores data associated with results of previously executed requests. As such, when a cluster encounters a previously executed request, the cluster may efficiently retrieve the cached result of the request from the in-memory query result cache or the cloud storage query result cache.
