Abstract: A dual-mode combined control method for a multi-inverter system based on a double split transformer is provided. For an extremely-weak grid, the method provides the dual-mode combined control method for a multi-inverter system based on a double split transformer. According to the method, the equivalent grid impedance at a point of common coupling (PCC) of one grid-connected inverter (GCI) in the multi-inverter system based on the double split transformer is obtained with a grid impedance identification algorithm, and the system sequentially operates in a full current source mode, a hybrid mode, and a full voltage source mode according to a gradually increasing equivalent grid impedance, thereby effectively improving the stability of the multi-inverter system based on the double split transformer during variation of the strength of the grid. The method ensures that the system can still operate stably in the extremely-weak grid.

Abstract: The present disclosure discloses an active perception system for a double-axle steering cabless mining vehicle. The adaptive perception system includes: an environment perception mapping module, a single-frame target detection module, a multi-frame data association module, a cloud control platform, a decision-making and planning module, and a vehicle control module. The double-axle steering autonomous driving mining vehicle can be actively adjusted to be in a forward advancing mode or a backward advancing mode according to the driving mode and comprehensive information of a sensor. The system improves working efficiency of mining area, and solves the problems of large perception blind area and high risk during turning, uphill and downhill of an existing autonomous driving perception system.

Abstract: An accelerator apparatus can include an interface to receive service requests from at least one processing core. The accelerator apparatus can include coprocessor circuitry coupled to the interface and comprised of multiple slices. The coprocessor circuitry can detect a performance type for the at least one processing core. The coprocessor circuitry can operate the plurality of coprocessor slices in at least one of a plurality of power modes based on the performance type detected for the at least one processing core. Some operations can be alternatively performed by an operating system on any processor coupled to the network.

Abstract: The present invention provides an inhibitor, an inhibitor composition, a drug and use thereof, and discloses that zkscan3 interacts with GATA1 and inhibits the transcription activity of GATA1, thereby affecting the production of red blood cells. Also, the invention also discloses that the zkscan3 gene can cause the denucleation obstacle of red blood cells by promoting the expression of KLF1. Based on this, the inhibitor of the present invention can affect the production and maturation of red blood cells by regulating the transcription of GATA1 and KLF1.

Abstract: A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.
