Abstract: Systems and methods for integrating computer applications is disclosed. The method includes receiving, at a primary client associated with a primary server, a request to interact with an object hosted by a secondary server independent of the primary server; initializing, by the primary client, an embedded component associated with the secondary server that is embedded in the primary client; and passing, by the primary client, a content identifier of the object to the embedded component. The embedded component configured to: request the secondary server to provide the object based on the content identifier; receive the object from the secondary server; and render the object for display in the primary client.

Abstract: A method and system for calibrating a PET scanner are described. The PET scanner may have a field of view (FOV) and multiple detector rings. A detector ring may have multiple detector units. A line of response (LOR) connecting a first detector unit and a second detector unit of the PET scanner may be determined. The LOR may correlate to coincidence events resulting from annihilation of positrons emitted by a radiation source. A first time of flight (TOF) of the LOR may be calculated based on the coincidence events. The position of the radiation source may be determined. A second TOF of the LOR may be calculated based on the position of the radiation source. A time offset may be calculated based on the first TOF and the second TOF. The first detector unit and the second detector unit may be calibrated based on the time offset.

Abstract: A computer device receives a user input to specify a natural language command. In response to receiving the user input, the computer device generates a semantic interpretation for the natural language command using a trained word similarity model, based on semantic annotations for a published data source. The computer device queries the published data source based on the semantic interpretation, thereby retrieving a dataset. The computer device generates and displays a data visualization based on the retrieved dataset.

Abstract: A method processes natural language commands (e.g., for data visualization). The method includes obtaining word embeddings (e.g., word vectors) for a set of words (or phrases) of a natural language. In some implementations, the set of words includes high-frequency or common words of the natural language. The method also includes training a word similarity model to identify similar words based on the word embeddings and a synonym database (a large lexical database, such as a thesaurus). The method also includes generating semantic annotations for a published data source using the trained word similarity model, based on the synonym database, and the word embeddings. The method also includes generating a semantic interpretation for a natural language command based on the semantic annotations for the published data source. The method also includes querying the published data source based on the sematic interpretation, thereby retrieving a dataset.

Abstract: There are provided a network identity authentication method, a network identity authentication system, a user agent device used in the network identity authentication method and the network identity authentication system, and a computer-readable storage medium. The network identity authentication method includes: acquiring, by a user agent, identity information and a registration rule of a target website via a network terminal; acquiring registration information for the target website based on the identity information or generating registration information for the target website according to the registration rule; transmitting the identity information and the registration information to a server agent and sending, by the server agent based on the identity information and the registration information, an authentication request to a website server to complete an authentication process.

Abstract: The invention relates to an SNP molecular marker tightly linked to weeping trait of Mei (Prunus mume Sieb.et Zucc.), and a detection method and use thereof. The present invention provides an SNP molecular marker tightly linked to weeping trait of Mei, which is located at 11182911 bp of chromosome 7 of Mei with a polymorphism of A/C. The present invention develops an SNP molecular marker tightly linked to weeping trait of Mei through the combination of GWAS analysis with the population selection method. The SNP molecular marker has good reproducibility and high accuracy in the identification of weeping/upright traits in the segregation population of filial generation of Mei, and achieves an accuracy of 96% or more in the single-molecule marker identification of weeping/upright traits.
