Abstract: The present invention relates to an ethanol foam sclerosing agent for vascular anomalies and a preparation method thereof. The ethanol foam sclerosing agent includes absolute ethanol, water, Tween 80 and a stabilizer. The ethanol foam sclerosing agent further includes hyaluronic acid. The mass composition of the ethanol foam sclerosing agent includes 32-42% of absolute ethanol, 0.5-2% of Tween 80, 0-25% (excluding 0) of egg yolk lecithin, 0-2% (excluding 0) of hyaluronic acid, and the balance of water. The stabilizer is hyaluronic acid or glycerin. Foam is prepared by the Tessari method. While the original therapeutic effect of ethanol is not changed, the side effect of the ethanol is significantly reduced.

Abstract: A method is described, which includes receiving, by a memory subsystem controller from a host system, a host read memory command that references a set of logical block addresses associated with a set of transfer units of a memory device. The controller converts the set of logical block addresses to a set of physical block addresses for the set of transfer units; generates a set of device read memory commands based on the physical block addresses, wherein each device read memory command references at least one physical block address; and generates a first aggregated device read memory command based on a first device read memory command and a second read memory command in response to determining that the first device read memory command is associated with the second device read memory command. The controller thereafter transmits the first aggregated device read memory command to the memory device.

Abstract: The disclosed technology is generally directed to code transparency. In one example of the technology, raw input data that includes version information that is associated with code is received. The version information includes pull requests associated with the code. Extracted key phrases are provided by performing a key-phrase extraction on the raw input data. A list of documents and a list of people are determined based at least in part on the extracted key phrases. A relevance ranking is performed on the list of documents and the list of people. Based on the relevance ranking, relevant documents and relevant people are determined, such that the relevant documents and the relevant people are relevant to the code. To a developer environment that is associated with the code, information associated with the relevant documents and/or the relevant people is provided.

Abstract: A molding method for producing a screw drill stator using an elastomer material includes: S1. sequentially roughening, cleaning and drying an inner surface of the stator tube; mixing an adhesive and a diluent, coating the mixture obtained on the inner surface, and heating it for later use; S2, uniformly coating a mold release agent on a surface of a mandrel mold, and heating or drying it naturally for later use; S3. assembling the processed stator tube and the processed mandrel mold to obtain an assembled mold; S4. performing a vacuum defoaming under negative pressure on a mixture obtained by uniformly mixing a prepolymer of the elastomer material with a defoaming agent; S5. uniformly mixing the defoamed prepolymer of the elastomer material with a curing agent, and pouring the obtained mixture into the assembled mold, sealing and curing the poured assembled mold by hierarchical heating to obtain the stator.

Abstract: A prepolymer of elastomer material for screw drilling tools and a preparation method thereof are provided. The prepolymer includes component A and component B, wherein the component A includes hydroxyl-terminated liquid rubber, polytetrahydrofuran diol, and polyether polyol; the component B includes at least one of an isocyanate, a cyanate, and a cyano compound; the mass ratio of the hydroxyl-terminated liquid rubber, polytetrahydrofuran diol, and polyether polyol is (0.2-1.0): (0.2-1.0): (0.2-1.0). Different molecular segments of different proportions are introduced through structural design, such that the molecular structure of the prepolymer has both rigid and flexible segments, thus to achieve an adjustable and controllable structure of the prepolymer; and the introduction of active groups makes the prepolymer to show good reactivity and processability.

Abstract: Methods, systems, and devices for metadata indication are described herein. A method includes receiving, from a host system, a read command to retrieve information from a first block of a memory device, identifying a transfer unit associated with the first block indicated in the read command, identifying an indicator in metadata of the identified transfer unit indicating that at least one sector of the transfer unit has been altered based at least in part on identifying the transfer unit, validating data of the transfer unit stored in the memory device based at least in part on identifying the indicator in the metadata, and retrieving the information stored in the first block based at least in part on validating the data of the transfer unit.

Abstract: A method for managing storage performance consistency, where the method determines a target throughput for writes to a memory sub-system, increases a tracking variable with a granularity based on the target throughput at fixed intervals, decreases the tracking variable based on writes of host data received from a host system to the memory sub-system, and adjusts a priority of host data writes to the memory sub-system relative to writes of reclaimed data from the memory sub-system in response to the tracking variable indicating a deviation from the target throughput.
