Abstract: A lipid delivery system, a virus-like structure (VLS) vaccine constructed therefrom, and a lipid particle capable of encapsulating an mRNA molecule encoding a SARS-CoV-2-specific antigen are provided. After the lipid particle encapsulates an mRNA molecule encoding a SARS-CoV-2 antigen, a SARS-CoV-2 S1 antigen protein can be embedded on a surface of an envelope structure of the lipid under specific buffer conditions to produce a VLS vaccine with an antigen-encoding mRNA molecule encapsulated inside and an outer membrane presenting a required viral antigen protein. The vaccine has a superior specific antibody-inducing ability to a SARS-CoV-2 mRNA vaccine and a polypeptide vaccine, can maintain a long-lasting high antibody level, and can also exhibit excellent immune binding abilities for the emerging different variants.

Abstract: The present disclosure discloses a method and system for controlling an autonomous mobile robot, and the autonomous mobile robot. The method includes: when cleaning in a current region, recognizing, by the autonomous mobile robot, information of a line object appearing in a cleaning path, where the information at least includes one of pose information of the line object, a length of the line object, and a cross-sectional radius of the line object; and determining a target control strategy matched with the recognized information from preset control strategies, and causing the autonomous mobile robot to execute the target control strategy.

Abstract: Provided are dynamic region division and region passage identification methods and a cleaning robot. The dynamic region division method includes: acquiring environment information collected by a robot when working in a first region; determining whether the robot has completed a work task in the first region, when a presence of a passage entering a second region is determined based on the environment information; and complementing a boundary at the passage to block the passage, when the work task is not completed. According to the technical solution provided by the embodiment of the present application, the occurrence probability of repeated sweeping and miss sweeping is reduced, and the cleaning efficiency is high. In addition, the technical solution provided by the embodiment of the present application relies on the environment information collected during the work, rather than relying on historical map data, so that the environmental adaptability is high.

Abstract: A computing resource monitoring service obtains a request from a third-party partner system to generate a first bus. In response to the request, the computing resource monitoring service updates an account associated with a customer of a remote service to indicate presence of the first bus. The computing resource monitoring service activates the first bus to establish an association with a second bus, obtain a set of events generated by a resource of the third-party partner system, and provides the set of events to the first bus. The computing resource monitoring service publishes the set of events to cause the second bus to distribute the set of events to another remote service.

Abstract: Embodiments of this application provide a link restoration method and apparatus, and a device. The method includes: if quality of a link between a first communications device and a second communications device does not meet a preset condition, detecting, by the first communications device within timing duration of a first timer, whether the link is restored, and obtaining a detection result, where the timing duration of the first timer is blockage duration of a link blockage resulting from a user movement; and determining, by the first communications device based on the detection result, whether to perform a link restoration operation, where the link restoration operation includes at least one of a beam tracking operation, a beam refinement operation, or a redo-beamforming operation.

Abstract: The present disclosure discloses an advertisement display method, a terminal device and a non-transitory computer-readable storage medium, wherein the method comprises sending an advertisement data request to a server in a power-on state; receiving the advertisement data returned by the server, wherein the advertisement data includes the advertisement data of the day when the advertisement data request is sent and of a predetermined number of days after the day; downloading advertisement materials according to the advertisement data; selecting an advertisement material for display upon the next power-on event.

Abstract: A set of one or more terms can be derived from the voiced user input. It can be determined that the set of one or more terms corresponds to a specific digital document in a computer system, and that the set of one or more terms corresponds to at least one computer-executable command. The determination that the set of one or more terms corresponds to the at least one command can include analyzing the set of one or more terms using a document-specific natural language translation data structure. The translation data structure can be a computer-readable data structure that is identified in the computer system with the specific digital document in the computer system. It can be determined that the set of one or more terms corresponds to an element in the document, and the at least one command can be executed on the element in the document.

Abstract: A switch is provided which is dynamically configurable via a network port thereon. One switch is employed to establish point-to-point electrical connections between devices under test (DUTs) and host devices coupled to upstream ports and downstream ports on the switch respectively. Two switches coupled to a network are employed to facilitate a distributed test lab. DUTs are coupled to upstream ports on a first switch which, based on communication with a test controller over the network, establishes a logical connection between the upstream port coupled to a particular DUT and the network. Host devices are coupled to downstream ports on a second switch which, based on communication with the test controller over the network, establishes a logical connection between the downstream port coupled to a particular host device and the network. A logical connection is also established across the network between the particular DUT and host device.
