  • Patent number: 11078502
    Abstract: A method and cell line for producing polyketides in yeast. The method applies, and the cell line includes, a yeast cell transformed with a polyketide synthase coding sequence. The polyketide synthase enzyme catalyzes synthesis of olivetol or methyl-olivetol, and may include Dictyostelium discoideum polyketide synthase (“DiPKS”). Wild type DiPKS produces methyl-olivetol only. DiPKS may be modified to produce olivetol only or a mixture of both olivetol and methyl-olivetol. The yeast cell may be modified to include a phosphopantethienyl transferase for increased activity of DiPKS. The yeast cell may be modified to mitigate mitochondrial acetaldehyde catabolism for increasing malonyl-CoA available for synthesizing olivetol or methyl-olivetol.

  • Patent number: 10891435
    Abstract: Machine translation is used to leverage the semantic properties (e.g., intent) already known for one natural language for use in another natural language. In a first embodiment, the corpus of a first language is translated to each other language of interest using machine translation, and the corresponding semantic properties are transferred to the translated corpuses. Semantic models can then be generated from the translated corpuses and the transferred semantic properties. In a second embodiment, given a first language for which there is a semantic model, if a query is received in a second, different language lacking its own semantic model, machine translation is used to translate the query into the first language. Then, the semantic model for the first language is applied to the translated query, thereby obtaining the semantic properties for the query, even though no semantic model existed for the language in which the query was specified.

  • Patent number: 10796100
    Abstract: A natural language processing system has a hierarchy of user intents related to a domain of interest, the hierarchy having specific intents corresponding to leaf nodes of the hierarchy, and more general intents corresponding to ancestor nodes of the leaf nodes. The system also has a trained understanding model that can classify natural language utterances according to user intent. When the understanding model cannot determine with sufficient confidence that a natural language utterance corresponds to one of the specific intents, the natural language processing system traverses the hierarchy of intents to find a more general user intent that is related to the most applicable specific intent of the utterance and for which there is sufficient confidence. The general intent can then be used to prompt the user with questions applicable to the general intent to obtain the missing information needed for a specific intent.

  • Publication number: 20200314461
    Abstract: Apparatus and methods for presentation of key frames. In one embodiment, an encoded video file is generated where one or more bits are assigned to key frames and minimizes the number of bits assigned to delta frames. Each key frame may be presented to a user during trick mode operation (e.g., fast forward, rewind, pause, or random seek operation). When the encoded video file is given to a packager, the packager generates a manifest file listing the byte information (byte offset and number of bytes) for each key frame in the encoded video file. When a user inputs a trick play mode command, the packager provides the manifest file to the client device of the user and the client device requests the bytes for the key frames of the video file from the content delivery network.
