Abstract: Typically, when a user switches sessions between devices, the user authenticates the sessions by providing user account information, password, and/or pin code input or other credentials. However, when the user is frequently switching sessions between devices, authenticating sessions may result in the user reducing or even stopping switching across mobile devices. Systems and methods according to this disclosure provide automatic session roaming across mobile devices using proximity authentication. Upon detecting an indication to initiate session roaming, the source device automatically roams the session on the source device to a target device based on a proximity of the source device to the target device. The session is handed off from the source device to the target device as an authenticated user session.

Abstract: Systems and method for performing X-ray computed tomography (CT) that can improve spectral separation and decrease motion artifacts without increasing radiation dose are provided. The systems and method can be used with either a kVp-switching source or a single-kVp source. When used with a kVp-switching source, an absorption grating and a filter grating can be disposed between the X-ray source and the sample to be imaged.

When used with a single-kVp source, a combination of absorption and filter gratings can be used and can be driven in an oscillation movement that is optimized for a single-kVp X-ray source. With a single-kVp source, the absorption grating can also be omitted and the filter grating can remain stationary.

Abstract: A service may provide an e-commerce platform through which users may search for, view, and purchase products. To ensure users receive relevant results when querying for particular products or product classes, a list of ranked classes may be generated, from which the query results are based. For example, products may be classified into classes and particular text from search data may be associated with one or more of the products based on click log data. For instance, input text from previously performed queries may be associated with products interacted with following those queries (e.g., products clicked on to view/purchase). Training data that associates the particular text with the respective one or more classes into which the clicked on products are classified may be generated, and in response to receiving a query including the particular text as input, the list of ranked classes may be generated based on the training data.

Abstract: Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for blockchain-based service source tracing are provided. A blockchain stores service certificates of multiple service dimensions which constitute multiple service certificate linked lists. A service system maintains a mapping relationship between a last node of each service certificate linked list and a service index of a service dimension that each service certificate linked list belongs to.

A service certificate of the target service dimension stored on the blockchain is queried based on a linked list pointer recorded in the last node. The identified service certificate is returned to the client.

Abstract: In some embodiments, a method obtains raw data from one or more packets received over a wireless channel via an antenna. The raw data comprises raw amplitude values and raw phase values. Each raw amplitude value and raw phase value corresponds to a respective OFDM symbol and subcarrier of a respective packet. The method further comprises processing the raw data according to an interference mitigation process and using the resulting calibrated amplitude values and calibrated phase values to determine weighted phase values. Each weighted phase value corresponds to a respective subcarrier. The method determines a phase variance for the antenna based on comparing the plurality of weighted phase values across the plurality of subcarriers. The method determines whether the wireless channel experiences line-of-sight propagation or non-line-of-sight propagation based at least in part on the phase variance.
