Abstract: The present disclosure discloses a preparation method of an aluminum nitride (AlN) composite structure based on a two-dimensional (2D) crystal transition layer. The preparation method of the present disclosure includes: transferring the 2D crystal transition layer on a first periodic groove of an epitaxial substrate; forming a second periodic groove staggered with the first periodic groove on the 2D crystal transition layer; depositing a supporting protective layer; depositing a functional layer of a required AlN-based material; and removing the 2D crystal transition layer through thermal oxidation to obtain a semi-suspended AlN composite structure. The preparation method of the present disclosure has low difficulty and is suitable for large-scale industrial production.

Abstract: The present invention provides a joint optimization method and system for delay and spectrum occupation in a cloud-edge collaborative network. The method includes: initializing a cloud-edge collaborative network, and generating a set of user requests; establishing a target function of minimum average end-to-end delay and minimum spectrum slot occupation of a user request; during processing of each user request based on the target function, sequentially determining whether a node and path selection uniqueness constraint, a mobile edge computing (MEC) server load constraint, a spectrum resource occupation and uniqueness constraint, a spectrum continuity constraint, and a spectrum consistency constraint are satisfied, where if all constraints are satisfied, the user request is successfully processed, and the process turns to step S4; or if any constraint is not satisfied, the user request fails to be processed; and calculating average end-to-end delay and spectrum resource occupancy of the user request.

Abstract: Embodiments of the present disclosure discloses a method of information displaying, apparatus and an electronic device. The method comprises: displaying at least two session screening identifications in a first display area of a first message page, the at least two session screening identifications comprising: a first screening identification for indicating that a new message in a session is notified with a first notification strategy, and a second screening identification for indicating that a new message in the session is notified with a second notification strategy; and displaying information of each session corresponding to a currently selected session screening identification in a second display area of a second message page. The method may only display sessions that match user requests, reducing operations of users searching for required sessions in all sessions lists and saving time for users to browse required sessions.

Abstract: Disclosed in the embodiments of the present application are a method and apparatus for group management, an electronic device, and a storage medium. A specific embodiment of the method includes: presenting, in a first interface, a first control configured to perform a management setting for a first group, where the first interface is an interface other than an interface of the first group; and completing a corresponding group management setting for the first group in response to an operation for the first control in the first interface.

Abstract: Embodiments of the disclosure disclose a method, apparatus and electronic device for information display. The method comprises: displaying at least two session filtering identifiers, a session corresponding to each session filtering identifier satisfying a filtering condition corresponding to the session filtering identifier; displaying information of respective sessions corresponding to a first filtering identifier in a preset display area of a message page, the first filtering identifier being a currently selected filtering identifier; in response to a message of a session corresponding to a second filtering identifier satisfying a preset condition, displaying information of the session in the preset display area, the second filtering identifier being other filtering identifier than the first filtering identifier. The method makes it possible that a message satisfying the preset condition under a filtering identifier which is not selected currently can be displayed in time.

Abstract: Method and apparatus for information processing, information interaction, tag viewing and information display are provided. The method for information processing comprises: receiving a tag adding operation triggered by a user for a target object; and generating a correspondence relationship according to the tag adding operation, wherein the correspondence relationship comprises a correspondence relationship between a target tag and the target object.

Abstract: An information display method and apparatus, and an electronic device are provided. The method includes: receiving an instruction for displaying a page for instant messaging; displaying, in response to the instruction, a display page for the instant messaging, where the display page includes a first display area and a second display area; and displaying contactor information in the first display area and displaying filtered information in the second display area, where the contactor information includes an identifier of at least one contactor and interaction information with the contactor, the filtered information includes a filter identifier and information of a message corresponding to the filter identifier; and a message corresponding to a filter identifier is obtained by performing filtering on messages to at least one contactor under a preset filtering condition corresponding to the filter identifier.
