Abstract: A high-precision multi-pole magnetoelectric encoder includes a mounting seat, a rotating shaft, a single-pole magnet ring, a single-pole signal processing board, a shielding shell, an n-pole magnet ring, an n-pole signal processing board, a housing, a conductive rubber pad, an aviation plug, bearings, copper columns, Hall components, and assembly screws. The magnetoelectric encoder improves the environmental adaptability and replaceability of the high-precision multi-pole magnetoelectric encoder by redesigning the structure of the multi-pole encoder. It eliminates errors caused by changes in the position of magnets and Hall sensors during the replacement process, reduces interference caused by the multi-pole magnet encircling the single-pole magnet, enhances resistance to electromagnetic interference, thereby increasing the detection accuracy of the magnetoelectric encoder, and improves the performance and competitiveness of the product.

Abstract: The present invention provides a cycloyl formyl and cycloyl ketone compounds, a preparation method therefor, and a pharmaceutical use. The present invention finds that the compounds shown in formula (I) better inhibits Zika virus and dengue virus infection and replication, may be used as a drug for treating and preventing diseases caused by Zika virus and dengue virus, and may also become a drug for treating and preventing diseases caused by other flaviviruses, such as yellow fever, West Nile virus infection, Japanese encephalitis, AIDS caused by HIV etc., and diseases caused by hand, foot and mouth virus infection etc. The compounds may treat disease caused by bacterial infections, including inflammatory bowel disease ulcerative colitis and Crohn's disease, diseases caused by Escherichia coli, diseases caused by Staphylococcus aureus etc., and diseases caused by Acinetobacter baumannii.

Abstract: Embodiments of the present invention disclose a method and an apparatus for data preheating, which relate to database technologies, so as to increase a responding speed of a database system, reduce frequent IO on a magnetic disk, and improve overall performance of the database system. The method includes: when a database is started, reading hit ratio information from a flash memory device and reading user configuration information from a hard disk; obtaining a union set of a preset hot data table in the user configuration information and a hot data table in the hit ratio information; determining the total number of to-be-loaded hot data blocks from the union set; according to the storage proportions, determining the to-be-loaded hot data block to be stored into a shared buffer and the flash memory device; and separately storing the to-be-loaded hot data block into the shared buffer and the flash memory device.

Abstract: The present invention provides a method and a system for configuring a storage device in a hybrid storage environment. The method includes: acquiring a plurality of attribute parameters of each storage device; performing calculation according to the attribute parameters to obtain a priority of each storage device; acquiring a storage priority of each data object; and performing matching according to the storage priority of each data object and the priority of each storage device, so as to store each data object into a storage device with a priority corresponding to the storage priority of the data object. Accordingly, configuration of a plurality of storage devices and a plurality of data objects in a hybrid storage environment can be implemented, which avoids manual involvement, thereby reducing security risks, improving performance of the system, and reducing energy consumption of the system.
