    摘要: Systems and methods for generating proposed search queries based on sequence semantics. The method includes receiving clickstream data from a database. The method also includes generating for each user a digital timeline based on the clickstream data. The method further includes determining for each user event pairs based on the digital timeline. The method also includes generating a vector matrix including the event pairs for each user. The method further includes receiving an initial search query from a user. The method also includes determining an intended user activity based on the initial search query. The method further includes generating proposed search queries based on the vector matrix, the intended user activity, and the initial search query.

    摘要: The present invention provides, among other things, methods of purifying messenger RNA (mRNA) including the steps of (a) precipitating mRNA from an impure preparation; (b) subjecting the impure preparation comprising precipitated mRNA to a purification process involving membrane filtration such that the precipitated mRNA is captured by a membrane; and (c) eluting the captured precipitated mRNA from the membrane by re-solubilizing the mRNA, thereby resulting in a purified mRNA solution. In some embodiments, a purification process involving membrane filtration suitable for the present invention is tangential flow filtration.

    摘要: Methods and systems are described herein for incremental bidding for electronic advertisements. A computing device generates, for a user during a first time period, first randomized bids for available impression opportunities, the first randomized bids based upon an estimated value and a first random factor and using a context of bid requests. The computing device transmits the first randomized bids to a remote device. The computing device determines whether interaction events associated with impression opportunities occurred. The computing device estimates second randomized bids based upon an estimated value and a second random factor and using the context. The computing device estimates a relative incrementality of a bidding policy based upon the second randomized bids over a bidding policy based upon the first randomized bids, and optimizes the bidding policy based upon second randomized bids. The computing device changes a production bidding policy based upon the optimized policy.

    摘要: A plasma chamber of a plasma processing system is provided. The plasma chamber defines a plasma channel having a first side and a second side oppositely disposed along a length of the plasma channel. The plasma chamber comprises a first section and a second section constructed from a dielectric material and an interface that bonds together the first and second sections at between a first flange of the first section and a third flange of the second section and between a second flange of the first section and a fourth flange of the second section.

    摘要: A system is provided for visualizing data in a computerized visual environment. The system comprises (i) a viewing device that displays, to a user of the viewing device, a graphical user interface within a virtual three-dimensional space, (ii) a handheld device configured to allow the user to customize the display of a three-dimensional data visualization within the graphical user interface using hand motions made by the user, and (iii) a computing device coupled to the viewing device and the handheld device. The computing device is configured to cause to display to the user on the viewing device a filter plane overlaying the three-dimensional data visualization, detect a position of the filter plane that is movable by the user in the graphical user interface, and alter the three-dimensional visualization in the graphical user interface based on the detected position of the filter plane.

    摘要: Methods and apparatuses are described for generating a recommended conversation topic flow. A server executes a topic modelling algorithm on voice call transcripts to determine a distribution of topics present in the transcripts. The server generates a historical topic flow for each transcript by determining topic-related words in text blocks in the transcript and assigning a score to each text block. The server categorizes each topic flow as positive or negative based upon outcomes associated with the transcript. The server trains a classification model using the categorized topic flows as input. The server captures a bitstream corresponding to a current voice call and converts the bitstream into unstructured text. The server executes the classification model on the unstructured text to determine whether a call topic flow is positive or negative. The server generates topic recommendations and transmits the recommendations to a second client device.
