Abstract: Embodiments of this application provide a video shooting method and an electronic device, and relate to the field of terminal technologies. The method is applied to an electronic device including a display, a first camera, and a second camera. The method includes: displaying, in a first region of the display, a first image collected in real time by the first camera, and displaying, in a second region of the display, a second image collected in real time by the second camera; responding to a detected user operation, displaying a third image in a third region of the display, and displaying a fourth image in a fourth region of the display, where the third region is different from the first region, and the fourth region is different from the second region.

Abstract: This application provides a photographing method and an electronic device. The electronic device can display a photographing preview interface, where the photographing preview interface includes a first image collected by a first camera and a second image collected by a second camera. If the first camera detects a first gesture, the electronic device displays a first identifier; and if the first camera detects a second gesture within a preset time after the first identifier is displayed, the electronic device continues to display the first image in the photographing preview interface, and stops displaying the second image.

Abstract: A large-scale MIMO (Multiple-Input Multiple-Output) wireless transmission method for millimeter wave/Terahertz networks is provided. In order to reduce the interruption of propagation in the millimeter wave/Terahertz band, a plurality of cells are combined into a wireless transmission network, the base station in each cell is equipped with a large-scale antenna array, and a unitary transformation matrix is used to achieve large-scale beam coverage for user terminals in the entire network. Moreover, in order to reduce the influence of the multipath and Doppler effects on transmission performance, received signals are synchronized for time and frequency in each receiving beam of a user terminal. The method allocates power for signal transmission according to the statistic information of synchronized equivalent channels, and gives an optimal power allocation matrix by iterative solution based on the CCCP (concave-convex procedure) and the deterministic equivalent method.

Abstract: Methods and systems for modifying software programs are disclosed. For instance, an example method for modifying a software program may include extracting, from a configuration program file, a future list of one or more future active entries relating to a future version of the software program and a future list of one or more future ghost entries relating to the future version of the software program, comparing the future lists of future active and ghost entries to current lists of current active entries and current ghost entries of a current version of the software program. Then, at least one upgrade or at least one downgrade of the current version of the software program is performed in response the comparison of the current and future lists.

Abstract: Examples include a network device to filter a packet for a packet type. The network device includes a filter to receive the packet and to determine whether the packet is a defined packet type. The network device also includes a Bloom filter to receive the packet from the filter based on the determination that the packet is a defined packet type and to determine whether the packet is a matched packet or an unmatched packet. A processing resource of the network device may receive the packet from the Bloom filter based on the determination that the packet is a matched packet and to determine whether the packet is an exact match.

Abstract: Suture dispensers for retaining armed sutures are disclosed. The dispenser disclosed is comprised of two flat panels of material that each have a central opening. A needle park is provided so that the needle is visible in and accessible though the central openings. In preferred embodiments, the needle park is made of a thin sheet of clear material. Several alternate needle park designs are also disclosed. The two panels are preferably locked together using edge locks in the form of corresponding slits and tabs formed on the panels themselves. In addition to being inexpensive, easy to manufacture and easy to fill, the disclosed dispensers is much thinner than current designs and thus requires less storage and shipping space. Methods of loading dispensers are also disclosed.
