Abstract: Disclosed in the present application are a power grid real-time scheduling optimization method and system, a computer device and a storage medium. The method comprises: acquiring power grid model parameters and power grid operation data; and according to the power grid model parameters and the power grid operation data, obtaining a power grid real-time scheduling adjustment strategy by means of a preset power grid real-time scheduling reinforcement learning training model. Massive operation data of a power grid and load flow calculation simulation technologies can be fused by means of reinforcement learning, and unlike a conventional algorithm, a complex and difficult-to-solve calculation model does not need to be established, so that rapid optimization adjustment of power grid real-time scheduling is achieved, the optimization adjustment cost is reduced, and the matching degree of power grid real-time scheduling and actual operation is improved.

Abstract: A downlight with multiple installation methods includes a cover, a reflector cup, a light source, a housing, and two springs. The housing has a boss extending along a thickness direction of the housing, and an opening surface of the boss extends radially outward to form a skirt. The cover is disposed on the opening surface of the boss to be spliced to the housing to form a cavity for accommodating the reflector cup and the light source. The reflector cup is disposed on a light-emitting surface of the light source to enable light emitted by the light source to be reflected to be emitted out of the cover. The housing includes two slots symmetrically located on an outer side of the boss, and the two springs are detachably connected to the two slots.

Abstract: The present invention relates to the immunotherapy of cancer. The present invention relates to develop personalized tumor antigen specific T cell lines to treat all types of cancer. The tumor antigen specific T cell lines provide potent and abundant tumor antigen specific T cells that selectively recognize cancer cells and destroy the cancer cells to cure cancer. Personalized tumor antigen specific T cell lines are a safe and effective immunotherapy for cancer treatment. It provides a promise that cancer will be no longer an incurable disease.

Abstract: A servo control strategy and system eliminates CEMF and load torque disturbances. The total disturbance at electrical portion is estimated using extended state observer based on a nominal model of armature winding with measured voltage impressed across two endpoints of armature winding and the measured armature current. The total disturbance at electrical portion is partially counteracted by feed-forward compensation. The remaining CEMF disturbance is eliminated with the aid of armature current feedback regulation. The electrical disturbance can be totally eliminated at inner loop of the system by combining feed-forward control with current feedback control. The total disturbance at mechanical portion is estimated using extended state observer based on a nominal model of drive system with measured armature current and actual speed. The total disturbance at mechanical portion is partially counteracted by feed-forward compensation.

Abstract: A method for detecting cancer from a biological sample previously withdrawn from the subject, in a subject includes determining in vitro the level of at least one biomarker in the biological sample. The at least one biomarker includes a phospholipid or a free fatty acid. A level of the at least one biomarker that is 2-fold greater than the level of at least one biomarker in a control is indicative of cancer in the subject.
