Abstract: The invention relates to a simple method for preparing an NADH and ethanol biosensing chip, applicable to NADH or ethanol detection in the fermentation field, clinical medicine and food engineering. The sensing material described in the present invention is simple in preparation and can be prepared in batches, the nanogold is uniformly distributed on the surface of nickel hexacyanoferrate, and the quality of the sensing chip prepared based on this material is controllable. The sensing chip uses ethanol dehydrogenase as a biorecognition element and is more selective. The sensor chip detects ethanol and NADH in a wide linear range without dilution at a single detection time of less than 30 s and can realize real-time monitoring of fermentation broth.

Abstract: A method of displaying secondary content is disclosed. The method receives historical behavior data and a search query for a user. The method extracts behavior features from the user's historical behavior and scores the user based on the behavioral features to create a user score specific to secondary content. The method uses the user score to display user specific secondary content to the user.

Abstract: Examples of the disclosure enable generating, maintaining, and/or updating a model configured to identify content for a segment. In some examples, a plurality of keywords associated with accessing webpages are retrieved. A plurality of keyword scores corresponding to the keywords are generated. Based on the keyword scores, a subset of keywords are identified as being associated with the segment. The subset of keywords are compared with content keywords associated with content to determine whether to include the content in a subset of content associated with the segment. Users associated with the subset of content are identified. Based on metrics associated with the users, the users are labeled for generating a training set associated with the segment. Aspects of the disclosure enable a predictive model to be generated, maintained, and/or updated in a calculated and systematic manner for increased performance.

Abstract: Systems, methods, and computer storage media having computer-executable instructions embodied thereon that maintain a targetable user inventory for digital advertising. In embodiments, a request is made for user data associated with a user identification. If the user data or user identification is not available, a list of alternative user identifications is ranked according to various criteria based on identification signals. A match is selected from the list of alternative user identifications and user data associated with the alternative user identification is communicated in response to the request.

Abstract: Methods and systems for maintaining user privacy preferences based on one or more user identifications across a plurality of applications are provided. Two or more user identifications are received with associated user privacy preferences. The received user identification is compared against other user identifications to determine if the user identifications relate to the same user. It may be determined that two user identifications are related if they have at least one browser property in common. A consolidated data stream of the user privacy preferences for the related user identifications is created. The consolidated data stream is communicated to one or more applications and propagated to maintain the user privacy preferences across the applications relating to the user identification.

Abstract: An implementation of the present invention provides a remote assistance method, system and terminal. The method comprises: establishing a connection between an assisted terminal and an assisting terminal through a communication protocol; designating a window that needs assistance and sending a screenshot of the window to the assisting terminal by the assisted terminal; displaying the screenshot of the window, executing an assistance operation on the screenshot of the window, and sending assistance operation information corresponding to the assistance operation to the assisted terminal by the assisting terminal; executing the assistance operation specified by the assisting terminal on the window that needs assistance by the assisted terminal, according to the assistance operation information. The implementation of the present invention improves operation accuracy and protects user's privacy.

Abstract: Large sets of unorganized data may provide little value in identifying useful observations from such data. For example, an online merchant may maintain a database of millions of user IDs (e.g., a cookie ID, a login ID, a device ID, a network ID, etc.) along with content viewed and/or actions taken with the user IDs, where minimal associations are known between user IDs. It may be advantageous to link together user IDs of respective users to capture a comprehensive view of respective users' activities. Accordingly, one or more systems and/or techniques for identifying a cluster of nodes based upon transforming a set of node pairings (e.g., pairings of related nodes) one or more times are disclosed herein. Iterative transformations may be performed until respective nodes are paired with merely their smallest neighboring node and are paired with no other node. In this way, node clusters may be identifiable.

Abstract: Systems, methods, and computer storage media having computer-executable instructions embodied thereon that utilize relevant user profile data for advertisement selection. An advertisement context string is referenced. One or more related context strings that are related to the advertisement context string are identified. The advertisement context string and the one or more related context strings are compared to user profile strings associated with a user. It is determined that at least one of the advertisement context string or the one or more related context keywords is similar to at least one of the user profile strings. Any of the similar strings can be utilized to select an advertisement to be presented to the user.

Abstract: Showing the most meaningful page as the first page of a book or content to the potential customer gives the customer a special first impression on the book or content. The present invention has significant impacts on the customer interest and purchase decision for the book or content. The present invention is disclosed, wherein by computing the historical statistics numbers for every page of the book or content as the pages meaningfulness measurements, selecting the page which has the largest statistics number and presenting the page to the customer first ahead of other less meaningful pages, and therefore giving the better customer's first impression on the book or content.
