Abstract: Embodiments of the present disclosure provides methods and systems for preparing a cathode component. The method may include obtaining a three-dimensional (3D) model of the cathode component; obtaining a predetermined parameter, wherein the predetermined parameter includes at least one of a scanning direction of laser, an energy distribution of laser, an output power of laser, or a scanning speed of laser; and controlling a 3D printer to perform, based on the 3D model and the predetermined parameter, a laser scanning on a raw material to obtain the cathode component.

Abstract: Embodiments of the present disclosure provide an X-ray tube. The X-ray tube may include a cathode assembly. The cathode assembly may include: a cathode configured to emit an electron beam; a cathode adjustment window disposed at a periphery of the cathode; and a controller configured to adjust emittance of the electron beams emitted from the cathode at different tube voltages by adjusting a potential difference between the cathode adjustment window and the cathode, so that a size of an electron beam spot formed by the electron beam matches a target focal point size.

Abstract: Provided are a compound as represented by formula I or a pharmaceutically acceptable salt thereof, and applications of the compound in preparing a medicament for preventing and/or treating a PDE-related disorder.

Abstract: A method is described, which includes receiving, by a memory subsystem, a memory command targeted at a memory array; determining, by the memory subsystem, if the memory command is a high priority memory command; and determining if the memory subsystem is processing any non-high priority memory commands. The memory subsystem enables a read page cache mode for processing the memory command in response to determining that (1) the memory command is a high priority memory command and (2) the memory subsystem is not processing any non-high priority memory commands Thereafter, the memory subsystem processes the memory command using the read page cache mode.

Abstract: Methods, systems, and devices for data stream processing for maintaining queues for memory sub-systems are described. A number of commands included in a queue of a plurality of queues of a memory die of a memory sub-system can be determined. Each queue can be associated with a respective priority level and can be configured to maintain a respective set of commands. A command can be assigned to the queue based on a number of commands included in the queue. One or more commands can be issued from the queues based on the respective priority levels of the queues.

Abstract: Methods, systems, and devices for managing queues of a memory sub-system are described. A first command can be assigned to a first queue of a memory die of a memory sub-system. The first queue can be is associated with a first priority level and the memory die can include a second queue associated with a second priority level different from the first priority level. The second queue can include a second command, where the first command and the second command are each associated with a respective operation to be performed on the memory sub-system. In some examples, the first command can be issued before the second command based on the first and second priority levels.

Abstract: Improved methods and compositions for safe and effective treatment of erythema or a symptom associated with erythema in a subject are described. The methods involve topically applying to an affected skin area a topical composition comprising about 0.3% to about 10% by weight of brimonidine and a pharmaceutically acceptable carrier.
