  • Publication number: 20230022109
    Abstract: Provided is a novel coronavirus vaccine using replication-deficient human type 5 adenovirus as a vector. The vaccine takes the replication-deficient human type 5 adenovirus that is lack of E1 and E3 in a combined mode as a vector, and HEK293 cells that integrate adenovirus E1 genes serve as a packaging cell line, and protective antigenic genes carried are optimized COVID-19 (SARS-CoV-2) S protein genes (Ad5-nCoV). The vaccine has good immunogenicity in both mouse and guinea pig models and can induce the body to produce a strong cellular and humoral immune responses in a short time. Research on the protective effect of hACE2 transgenic mice shows that 14 days after a single Ad5-nCoV immunization, the viral load in lung tissues can be significantly reduced. It shows that the vaccine has a good immune protection effect against COVID-19.

  • Patent number: 11542913
    Abstract: A wave energy converter is provided which includes a central body including a nacelle, the nacelle housing at least one power take off. The wave energy converter also includes a first float and a first float arm coupled to the nacelle on a first side, and a second float and a second float arm coupled to the nacelle on a second side. The first float is rotatably coupled to the nacelle, the first float and the first float arm forming a first body configured to rotate, where the first body is operatively coupled to the at least one power take off such that relative motion between the first body and the central body generates energy in the at least one power take off. In one embodiment, the central body has a low reserve buoyancy, where the reserve buoyancy of the central body is lower than the reserve buoyancy of either of the first float and the second float, to minimize a heave response of the central body relative to the first float to increase output of the wave energy converter.

  • Patent number: 11539650
    Abstract: A method, system, and computer-usable medium are disclosed for identifying areas to improve an interactive conversational system, such as a chatbot. A stream of stream of conversational interactions C (C1, C2, . . . , Cn) between users and the interactive conversational system is received. An intent clustering model is periodically applied to the stream to form an incremental clustering based on a set of derived intents to form a mapping from a first set of conversational characteristics to a first set of intents and a second set of conversational characteristics to a first set of unclear intents. Information is provided related to the second set of conversation characteristics.

  • Patent number: 11521078
    Abstract: An approach is provided that receives a question at a question-answering (QA) system. A number of passages are identified that are relevant to the received question. A question knowledge graph is generated that corresponds to the question and a set of passage knowledge graphs are also generated with each passage knowledge graph corresponding to one of the identified passages. Each of the passage knowledge graphs are compared to the question knowledge graph with the comparison resulting in a set of knowledge graph candidate answers (kgCAs). A set of candidate answers (CAs) is computed by the QA with at least one of the CAs being based on one of the kgCAs.

  • Publication number: 20220375319
    Abstract: Disclosures relate to a sensor system and arrangements having different sized removable spacers. The spacers may be mixed and matched as needed or desired to compensate for misalignment conditions. Further, different spacer combinations and adjustments may be guided by a security management computing device. Variations in configurations of mounting surfaces, such as door and window assemblies, may be accommodated. Alignment of a transmitter or a receiving device, e.g., a magnetic device, with respect to a transmitter or receiving device despite misalignment of the components due to, for example, uneven surfaces of a door or a window, or a respective frame may be achieved.

  • Publication number: 20220315949
    Abstract: A single plasmid vector system for packaging recombinant human adenovirus type 4. The vector system contains an E3 region-deleted human adenovirus type 4 (HAdV-4 or Ad4) genome, a vector sequence for amplifying plasmids in bacteria, a pBR322 replication origin, a kanamycin resistance gene, and a replication control sequence; and an exogenous gene embedding site is located behind a packaging signal of the human adenovirus type 4 and in front of an E1 region. The present invention further provides a method for packaging the recombinant human adenovirus type 4 by the single plasmid vector system and an application in vaccine and drug preparation. The vector system can be used for rapidly and efficiently preparing a human adenovirus type 4 vector recombinant virus for stably expressing an exogenous gene, and has a good application prospect in the fields of preparation of a diagnostic kit, a vaccine, a gene therapy kit and/or a tumor therapy drug, etc.
