Abstract: A steel ladle drainage method is achieved by using a steel ladle structure. Vacuum interlayers are provided within an upper nozzle, an upper fixed plate, a lower fixed plate and a sliding plate of the steel ladle structure respectively. In the steel ladle drainage method provided by the present invention, a metal drainage agent is used to replace the drainage sand in the prior art, the metal drainage agent is melted by the liquid steel and deposited in the upper nozzle, the sliding plate with the vacuum interlayer and the upper nozzle with the vacuum interlayer have the insulation effect on the melted metal drainage agent. Moreover, through moving the sliding plate, the two pouring holes of the upper and lower fixed plates are connected with each other, the metal drainage agent enters the tundish through the pouring holes and the lower nozzle under the action of gravity.

Abstract: A method may include obtaining an image of an object; obtaining a target artifact identification model; determining target artifact feature information by inputting the image into the target artifact identification model, the target artifact feature information indicating a feature of one or more artifacts in the image; obtaining a target artifact extent determination model; determining target artifact extent indication information by inputting the image and the target artifact feature information into the target artifact extent determination model, the target artifact extent indication information indicating an influence extent of the one or more artifacts on an image quality of the image; in response to determining that the influence extent is greater than or equal to the extent threshold, outputting a notice of the one or more artifacts of the image.

Abstract: The present invention relates to the field of cell therapy, and specifically relates to a method for producing a mesenchymal stem cell population, the mesenchymal stem cell population and a culture supernatant thereof produced by the method, and a pharmaceutical composition containing such cells or the culture supernatant thereof. The present invention further relates to use of the mesenchymal stem cell population and the culture supernatant thereof for preventing and treating diseases.

Abstract: The present invention provides an electronic device and a method for adjusting a touch-control area thereof. The touch-control area of a touch-control display unit of the electronic device has a first touch-control area. The method for adjusting a touch-control area includes receiving a touch-control area adjustment command; adjusting the touch-control area of the electronic device to a second touch-control area in response to the touch-control area adjustment command; and displaying a tag used for representing the second touch-control area; wherein, when an input from the second touch-control area is received, an operation corresponding to the input is executed; when an input from outside of the second touch-control area is received, an operation corresponding to the input is not executed.

Abstract: Disclosed are an application management method and device, applied to a first device connected to a second device. The method includes mapping at least one application in the second device, to obtain at least one corresponding application identifier; detecting a first operation; when the first operation satisfies a first preset condition, determining an application identifier of a first application according to the at least one application identifier; detecting a second operation; when the second operation satisfies a second preset condition, obtaining a corresponding application management command according to the second operation; and sending the application management command to the second device, so that the second device manages the first application according to the application management command.
