Abstract: The present disclosure relates to data transmission methods, systems, and apparatuses. In one example method, a first device sends first information of a first data block to a second device. The second device searches, based on the first information, a first index for a second data block similar to the first data block, and sends second information of the second data block to the first device. The first device locally obtains, based on the second information, a reference block that is the same as the second data block, compresses a difference part of the first data block relative to the reference block to obtain first compressed information, and sends the first compressed information to the second device. The second device obtains the first data block based on the first compressed information and the second data block.

Abstract: This application provides a data processing method and a storage device, and belongs to the field of storage technologies. In this application, the storage device performs deduplication and compression based on different granularities, deduplicates data based on a large granularity, and compresses the data based on a small granularity. Therefore, a limitation that a deduplication granularity and a compression granularity need to be the same is removed. A deduplication ratio decrease caused by an excessively large granularity and a compression ratio decrease caused by an excessively small granularity are avoided to some extent, to improve an overall reduction ratio of deduplication and compression.

Abstract: The disclosure relates to the technical field of medicine and in particular to a polyethylene glycol conjugated drug of formula I or a pharmaceutically acceptable salt thereof. The disclosure further relates to a method for preparation and an intermediate of the polyethylene glycol conjugated drug or a pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the polyethylene glycol conjugated drug or a pharmaceutically acceptable salt thereof, and use of the polyethylene glycol conjugated drug or a pharmaceutically acceptable salt thereof in preparation of a medicament.

Abstract: This application discloses a data compression method and a computing device. The disclosed method is applied to the computing device. The method includes receiving, by the computing device, to-be-compressed data, and identifying a data type of the to-be-compressed data. The method further includes selecting one or more data compression models based on the identified data type and compressing the to-be-compressed data based on the selected one or more data compression models.

Abstract: A data transmission method, a data transfer device, and a system, where the data transmission method may include receiving, by a first device using a first Ethernet interface, packet data sent by a first packet handling switching (PHS) network device, receiving, using a first common public radio interface (CPRI) port, in-phase/quadrature (I/Q) data sent by a first component, where a format of the I/Q data conforms to a CPRI protocol, converting, by the first device, the packet data into conversion data whose format conforms to the CPRI protocol, carrying, by the first device, the conversion data and the I/Q data in transmission resources on a CPRI channel, and sending the conversion data and the I/Q data carried in the transmission resources to a second device.
