Abstract: A method produces tantalum powder. The method includes: (1) uniformly mixing a tantalum powder raw material, metal magnesium and at least one alkali metal and/or alkaline earth metal halide, loading the mixture into a container, and putting the container in a furnace; (2) raising the temperature of the furnace to 600-1200° C. in the presence of inert gas, and soaking; (3) at the end of soaking, lowering the temperature of the furnace to 600-800° C., vacuumizing the interior of the furnace to 10 Pa or less, soaking under the negative pressure so that the excessive metal is separated; (4) thereafter, raising the temperature of the furnace to 750-1200° C. in the presence of inert gas, and soaking so that the tantalum powder is sintered in the molten salt after oxygen reduction; (5) then cooling to room temperature and passivating to obtain a mixed material containing halide and tantalum powder; and (6) separating the tantalum powder from the resulting mixture.

Abstract: Dynamic snapshot scheduling techniques are provided using storage system metrics. One method comprises obtaining a schedule for generating snapshots of a portion of a storage system; automatically adjusting snapshot generation parameters in the schedule based on: (i) a current storage pool usage metric, (ii) an input/output metric of at least one storage resource in the portion of the storage system, (iii) a measure of snapshots in a destroying state, and/or (iv) a measure of a number of created snapshots; and initiating a generation of a snapshot of the storage system portion in accordance with the adjusted schedule. A snapshot generation frequency may be increased in response to an increase of: the current storage pool usage metric, the number of snapshots in the destroying state, and/or the number of created snapshots. A snapshot generation frequency may be decreased in response to an increase of the I/O metric of the at least one storage resource.

Abstract: Automatic file system capacity management techniques are provided using file system utilization prediction. One method comprises obtaining input data representing a utilization of a storage capacity of a file system of a given storage system; predicting a future utilization of the storage capacity of the file system based on a portion of the obtained input data; and automatically adjusting the storage capacity of the file system based at least in part on a result of a comparison of the predicted utilization of the storage capacity to a current utilization of the storage capacity. The comparison of the predicted utilization to a current utilization of the storage capacity may comprise comparing the current utilization of the storage capacity to the predicted utilization of the storage capacity for at least first and second time periods following a current time period to determine a trend of the utilization of the storage capacity.

Abstract: The present invention relates to application of gossypol and its optical isomers to preparation of an anti-Coronavirus drug. Specifically disclosed is application of pharmaceutically acceptable salts, solvates, isotopes, stereoisomers, stereoisomer mixtures, and tautomers of the gossypol and its optical isomers to preparation of a drug for preventing and/or treating a disease caused by a Coronavirus. The Coronavirus is MERS-CoV, SARS-CoV, or SARS-CoV-2. It is found in the present invention for the first time that the gossypol and its optical isomers can inhibit the activity of Coronavirus 3CL proteases to achieve an anti-Coronavirus effect. The half maximal inhibitory concentrations of gossypol and (?)-gossypol to SARS-CoV proteases and SARS-CoV-2 3CL proteases are all lower than 10 ?M. The anti-Coronavirus 3CL protease effect is good. Therefore, the gossypol and its optical isomers have the potential for use in the preparation of a drug for preventing and/or treating novel Coronavirus infections.

Abstract: Fabrication and use of an X-ray detector scan interface having separate enable and reset lines for each line (e.g., row) of pixels is described. In certain implementations, the respective enable and reset lines are connected such that activation of an enable line for a given line of pixels is concurrent with activation of a reset line for a different (e.g., preceding) row of pixels. In this manner, readout of one row of pixels is performed in conjunction with resetting the row of pixels readout in the preceding operation. In another technical implementation, a non-rectangular detector is divided into quadrants, with alternating quadrants configured for scan module or data module operations such that no quadrant has overlapping scan and data interconnections at the connection finger regions.

Abstract: The effects of electromagnetic interference (EMI) on X-ray image data is corrected by characterizing the EMI and processing the image data to subtract the EMI effects from the image data. The X-ray image data, along with offset data, are collected in a conventional manner, affected by EMI if present, and EMI-characterizing data is immediately collected thereafter by disabling rows of a digital detector (FET off). The EMI-characterizing data, then, is not affected by the presence of image data, and can be used to characterize the amplitude and frequency of the EMI. The EMI-characterizing data is assured of being in phase with the collected image and offset data due to its collection in the same image acquisition sequence immediately following the collection of image and offset data. Artifacts due to the presence of EMI are thus eliminated from reconstructed images based upon the corrected data.
