  • Patent number: 10308717
    Abstract: The invention provides compositions and methods for treating diseases associated with expression of EGFRvIII. The invention also relates to chimeric antigen receptor (CAR) specific to EGFRvIII, vectors encoding the same, and recombinant T cells comprising the anti-EGFRvIII CAR. The invention also includes methods of administering a genetically modified T cell expressing a CAR that comprises an anti-EGFRvIII binding domain.

  • Patent number: 10282237
    Abstract: Systems and methods for implementing an application programming interface (API) that controls operations of a machine learning tuning service for tuning a machine learning model for improved accuracy and computational performance includes an API that is in control communication the tuning service that: executes a first API call function that includes an optimization work request that sets tuning parameters for tuning hyperparameters of a machine learning model; and initializes an operation of distinct tuning worker instances of the service that each execute distinct tuning tasks for tuning the hyperparameters; executes a second API call function that identifies raw values for the hyperparameters; and generates suggestions comprising proposed hyperparameter values selected from the plurality of raw values for each of the hyperparameters; and executes a third API call function that returns performance metrics relating to a real-world performance of the subscriber machine learning model executed with the propose

  • Patent number: 9744937
    Abstract: The present invention is an improved safety harness for animals riding in a motor vehicle, wherein the harness prevents or greatly reduces the chance of the animal's lower quarters from being forced under the animal's head and shoulders, reduces the amount of rotational movement, reduces the side to side movement, reduces the chance for the dog to be forced off the car seat and reduces the amount of head excursion during a vehicle crash or a sudden stop.
