Abstract: A computer-implemented method is described which comprises generating a representation of a digital space and a representation of the physical space using an audiovisual feed received from a camera proximate to a display located in the physical space. The representation of the digital space is generated using user information identifying a remote user associated with the display and presence information relating to the remote user and the digital representation comprises an avatar of the remote user. The representation of the digital space is output to the display located in the physical space and the representation of the physical space it output to a computing device associated with the remote user. The method further comprises dynamically updating the representation of the digital space and/or physical space in response to changes in the user information and presence information.

Abstract: Embodiments of this disclosure disclose a method for data security check in an integrated circuit, and a medium. The method includes: determining, according to an address corresponding to a write pointer, a first address segment in which a first set of data is written into a first memory located in the integrated circuit; storing the first set of data into a storage space of the first address segment in the first memory; determining target encoded data based on the first set of data; storing the target encoded data into a second memory located in the integrated circuit, where the first memory is different from the second memory; and performing, based on the target encoded data, security check on a second set of data that is read from the first memory.

Abstract: The present invention relates to a tetrahydrocarbazole compound, and a pharmaceutical composition and the use thereof. The tetrahydrocarbazole compound is a compound as represented by formula (I), an optical isomer or a pharmaceutically acceptable salt thereof. The provided tetrahydrocarbazole compound, on one hand, can jointly inhibit OCT4 at the transcriptional and functional levels by means of targeting OCT4 and JAK to promote CSC differentiation, and on the other hand, inhibits differentiated tumor cells by means of inhibiting a JAK/STAT pathway. The compound provided in the present invention acts on two drug targets of OCT4 and JAK/STAT in tumor cells, therapy synergistically inhibiting tumor proliferation and metastasis by means of a dual-targeting effect, and can be used for preparing a drug for treating and/or preventing of cancers.

Abstract: A multifunctional rotating control device (RCD) is provided. The multifunctional RCD includes an RCD assembly and a flow detection module. Further, the RCD assembly includes a body and a rotating sealing assembly.

Abstract: A computer-implemented conditional network embedding method to map nodes of a given network, comprises a set of links between the nodes, onto points in a d-dimensional Euclidean space wherein d is equal to 1 or larger. The method comprises identifying and modeling information about structural properties of the network related to the nodes and the set of links between them, and searching an embedding which maps information of the network which is not part of or implied by these structural properties onto points in the d-dimensional Euclidean space.

Abstract: A wireless sensor network including a plurality of Smart Sensors coupled to a wide area network such as the Internet via a Wireless Sensor Coordinator. Each wireless sensor network comprises a plurality of Smart Sensors, each operable to measure one or more physical quantities. Each wireless sensor communicates the measured data to a Wireless Sensor Coordinator which then stores the collected data in memory. The Wireless Sensor Coordinator further includes a web server operable to post a web site on a network that is accessible by a common web browser. Upon receiving a request for sensed data via the web site, the Wireless Sensor Coordinator retrieves the appropriate measured and stored data and converts it into HTML format pages which are then posted on the web site for review by the requestor.
