  • Patent number: 9597393
    Abstract: The invention provides novel immunological adjuvants and methods for identification of such adjuvants. The invention further provides methods and compositions for eliciting an immune response to an immunogen using the novel adjuvants. The adjuvants can be employed with any suitable immunogen, including proteins, peptides, lipids, and carbohydrates. The immunogen can be derived from a virus, a cancer, or a diseased cell. The elicited immune response can be cellular, humoral, or both.

  • Publication number: 20140019128
    Abstract: Described herein are systems and methods for transforming a speech input into machine-interpretable structured data. In some embodiments, a system may include an automated speech recognition (ASR) engine configured to receive a live speech input and to continuously generate a text of the live speech input, a natural language processing (NLP) engine configured to transform the text into machine-interpretable structured data, and a user interface device configured to display the live speech input and a corresponding portion of the structured data in a predetermined order with respect to the structured data. In some embodiments, the method may include the steps of receiving a speech input with a speech capture component of a user interface device, generating a text from the speech input, identifying textual cues in the text, modifying the text based on the textual cues, and transforming the modified text into machine-interpretable structured data.
