Abstract: Disclosed are a method, a device and a non-transitory storage medium. The method includes: deploying a detection satellite to fly in one detection orbital plane opposite to the satellites in the large-scale constellation, to sequentially detect satellites flying in one target orbital plane of the large-scale constellation in a manner that an approach distance between the detection satellite and a satellite being detected is within a set detection distance, transmitting the detection satellite from the one detection orbital plane to another detection orbital plane in virtue of Earth oblateness perturbation, so as to sequentially detect satellites flying in another target orbital plane of the large-scale constellation in a manner that the approach distance between the detection satellite and a satellite being detected is within the set detection distance, and stopping the detection satellite from detecting until all satellites of the large-scale constellation have been detected.

Abstract: The present disclosure belongs to the technical field of biological products for veterinary medicine, and specifically relates to a recombinant foot-and-mouth disease virus (FMDV) with a reduced immunosuppressive activity, a preparation method and use thereof, and a recombinant vaccine strain. According to the present disclosure, it is firstly discovered that FMDV 3B protein has an immunosuppressive function, and key sites for exerting the immunosuppressive function are found. A recombinant FMDV vaccine strain with a lost immunosuppressive function in FMDV 3B protein is constructed by introducing amino acid mutations into three repeated copies of FMDV 3B protein.

Abstract: Disclosed are a method, a device, an apparatus for capturing a non-cooperative target using a space robotic arm, and a non-transitory storage medium, and relates to the technical field of on-orbit servicing. The method is applied to a space robotic arm with a magnetic capture device as an end actuator. The method includes: establishing a magnetic attractive force model for the magnetic capture device, determining a magnetic attractive force characteristic of the magnetic capture device based on the magnetic attractive force model, determining a capture strategy for the non-cooperative target based on the magnetic attractive force characteristic of the magnetic capture device, capturing the non-cooperative target according to the capture strategy, and determining whether the non-cooperative target is captured based on a preset determination condition.

Abstract: An embodiment includes identifying, during a video conference attended by a first attendee, other attendees of the video conference. The embodiment renders a virtual meeting environment including virtual representations of the other attendees, where the rendering includes accessing relationship characteristic data indicative of relationships between the first attendee and other attendees. The embodiment calculates positions for virtual representations of the other attendees in the first attendee's virtual field of view based on the relationship characteristic data. The embodiment also detects simultaneous speech from two of the other attendees and, in response, directs the individual speech from each of the other attendees to respective audio channels.

Abstract: A prediction method, including: creating a candidate list corresponding to a coding mode for the coding mode used by a coding block in an original picture, wherein the coding mode includes a first affine motion mode or a second affine motion mode, a reference block in the candidate list is spatially adjacent to the coding block, and the reference block is coded using the first affine motion mode or the second affine motion mode; performing affine motion estimation on the coding block according to the candidate list corresponding to the coding mode to obtain coding parameters corresponding to the coding block; and performing predictive coding on the coding block on the basis of the coding parameters corresponding to the coding block.
