Abstract: A method, belonging to the field of road disease prevention technologies, for constructing a simulation model for roadbed diseases, a test method, and a system, where a simulation model for roadbed diseases is first constructed, and based on the model, an experimental method is performed to simulate diseases such as roadbed settlement, cracks, loosening, and pipeline breakage. Data of multi-sensing devices is associated with different diseases in different control groups, data statuses of various roadbed diseases in complex scenarios are acquired, and data patterns are summarized through control tests, to obtain sensor thresholds when the diseases occur in actual roadbed conditions, thereby providing a basis for road disease prevention.

Abstract: Disclosed herein are a video processing method and apparatus, an electronic device and a storage medium. The video processing method comprises: receiving a detection operation for a video; in response to the detection operation, detecting invalid audio clips in the video, and displaying invalid audio clip information; receiving a deletion operation for a video clip corresponding to target invalid audio clip information; and in response to the deletion operation, deleting the video clip corresponding to the target invalid audio clip information in the video.

Abstract: Provided are a music extension method and apparatus, an electronic device, and a storage medium. The music extension method includes the following: receiving a target triggering operation of extending to-be-extended music; in response to the target triggering operation, determining a target music segment according to the music feature of the to-be-extended music; and splicing the target music segment to the target position of the to-be-extended music to obtain extended target music.

Abstract: A compound with anti-drug resistant bacteria activity having the following formula (I): is disclosed. A method of preparing the compound of formula (I) is also disclosed.

Abstract: The present invention provides a floor cleaner and a water sink structure thereof. In the present invention, a water sink is formed on a surface of a cleaning cylinder by a rotating roller, and a conventional water sink structure formed by a shell water sink and a filter screen is not required, so that the structure is simpler. Since a water outlet conduit and a water pumping conduit are arranged vertically to the surface of the cleaning cylinder, water is discharged and pumped on a surface of an outer sponge layer, the water supply and water pumping systems will not be blocked, and the water discharge effect and the water pumping effect are better.

Abstract: The present invention provides a calculation method for visual navigation integrity monitoring. With the method, by use of an appropriate visual positioning model, a mathematical algorithm and rich navigation measurements, the positioning accuracy and availability of positioning results are improved, and the problem of insufficient performance of satellite integrity algorithms caused by impossible guarantee of availability of a GNSS in complex environments is solved, which is helpful to realize aircraft accurate approach and automatic landing and of great significance to ensure the safety of aviation flight.

Abstract: The disclosed technology teaches catch-up replication, replicating to a target machine, a set of snapshots including replicated snapshots and un-replicated snapshots, stored in sequence at a source machine, that backup one or more virtual machines.

Abstract: A system, method, and set of protocols for dynamic group communication are provided for enabling dynamic process migration and dynamic group membership management. A process in a group receives and distributes a migration signal. Group communication continues while the processes in the group asynchronously reach a global superstep and then a synchronization point. The processes then spawn a new process on a new device and update group membership information. The new process operates in continuous execution with the new group.
