Abstract: A model predictive decomposition control method and device for an open-winding five-phase permanent magnet synchronous motor is provided. The method includes obtaining the voltage component in the stationary coordinate system under the orientation of the rotor magnetic field, synthesizing the virtual voltage vector that can eliminate the voltage vector in harmonic space according to the vector distribution of the five-phase permanent magnet synchronous motor under the voltage source inverter. The open winding permanent magnet synchronous motor topology is equivalent to the superposition of the independent actions of two inverters. The voltage vector generated by a single inverter is predicted through the mathematical model of the motor. The expected increment is a judgment condition to determine whether the open winding system uses one of the two inverters to maintain the normal operation of the open winding system, or the first inverter is clamped and the second inverter generates the remaining increment.

Abstract: A storage system is provided. The storage system includes a plurality of non-volatile memory modules a storage controller operatively coupled to the plurality of non-volatile memory modules, the storage controller comprising a processor. The process is to receive a set of data blocks to be stored in the plurality of non-volatile memory modules. The processor is further to program the set of data blocks at a first location of the plurality of non-volatile memory modules. The processor is further to determine whether a failure occurred while programming the set of data blocks in the plurality of non-volatile memory modules. The processor is further to reprogram a subset of the data blocks at a second location of the plurality of non-volatile memory modules, a number of blocks in the subset of data blocks based on durabilities of the set of data blocks, in response to determining that a failure occurred while programming the set of data blocks at the first location.

Abstract: A video processing method and apparatus, an electronic device and a storage medium are provided. The method includes: displaying an identifier of a target video in a session interface, the target video being a video sent or received by a current user; displaying a preset control in an associated position of the identifier; and in response to a triggering of the preset control, executing a target action on the basis of the target video.

Abstract: The robust dispatch method for flexibility resources of large-scale data center microgrid clusters characterizes overall scheduling capacity of multiple flexibility resources in each data center microgrid by establishing a virtual battery model, constructs an equivalent model of scheduling capacity of data center microgrid cluster based on constraint space superposition methods of Minkowski summation, and fully exploits flexibility of output power regulation of distributed generator sets and energy storage of the data center microgrid cluster as well as demand response characteristics of loads, so as to obtain regulation domain of aggregate power of the data center microgrid cluster.

Abstract: The present invention discloses an application of chebulinic acid in preparation of anti-rotavirus drugs, which belongs to the technical field of anti-rotavirus drugs. Chebulinic acid has the effect of resisting rotavirus biosynthesis, has no effect of resistance to rotavirus adsorption and direct killing, and can inhibit the gene expression of VP6 to play an anti-RV role. Network pharmacology analysis indicates that chebulinic acid acts on rotavirus-related genes. Compared with the prior art, the present invention has the beneficial effects that: the present invention relates to an application of chebulinic acid in preparation of anti-rotavirus drugs.

Abstract: Provided are an unread message display method, an electronic device, and a storage medium. The method includes the following: A message list page is displayed, and an unread message thumbnail is displayed on the message list page. A first trigger operation acting on a target unread message thumbnail is received. In response to the first trigger operation, an unread message display area is displayed; and a target unread message corresponding to the target unread message thumbnail is displayed in the unread message display area. A second trigger operation for switching the current unread message displayed in the unread message display area is received. In response to the second trigger operation, the current unread message displayed in the unread message display area is switched to an unread message sent by a target sending user other than the current unread message.
