LIGHT QUANTUM PHASE MODULATING SYSTEM

Using a high-speed serial data transceiver (1130) to generate two paths of high-speed electric pulse signals (P1, P2). After the signals pass through a gain-control network (1200), the signals are used for driving an electro-optic phase modulator (PM) to realize the phase modulation of light quantum signals.

The scheme discloses a method for realizing DeltaLake data lake index based on Elasticsearch, during lake entering, Spark extracts source data, Schema analysis is performed on an extracted data set, meanwhile, data storage address information is added to form an index structure, in the lake entering process, for data of different data sources, if a user does not select a column for creating an index, the index of the DeltaLake data lake is created, and the index of the DeltaLake data lake is created. An index structure is automatically deduced by the system, and natural classification based on data source types is achieved. During search, different source data have different index structures, so that the source data are classified, and in the query process, query is performed in a certain type or several types of data range according to the designation of a user, and a certain type of data is designated for quick query. According to the scheme, the Elasticsearch is introduced for a Delta ...

Preparation, recombinant expression method and medical application of antibacterial substance gibberellin

The invention discloses a preparation and recombinant expression method of an antibacterial substance gemmectin and medical application of the antibacterial substance gemmectin, a novel bacteriocin antibacterial substance gemmectin is obtained by purifying paenibacillus jilin culture supernatant, and amino acid sequence characteristics and coding genes of the novel bacteriocin antibacterial substance gemmectin are determined. The recombinant gibberellin with antibacterial activity is obtained by using an escherichia coli prokaryotic expression system. The gibberellin has the advantages of strong antibacterial activity, wide antibacterial spectrum, excellent stability, extremely low cytotoxicity and hemolytic activity, and no drug resistance. Milk fresh-keeping application analysis shows that the gemmectin can efficiently kill enterococcus faecium in milk, the storage life of the milk is prolonged, and the quality of the milk is not influenced. Animal anti-infection experiments show that ...

Method for realizing interconnection between data lake and Ceph RGW based on swift protocol

The invention relates to a method for realizing interconnection between a data lake and a Ceph RGW based on a swift protocol. The method solves the problems of long time consumption and high hardware cost when Delta Lake performs systematic operation on data stored in Ceph RGW in the prior art. The method comprises the following steps: S1, creating a Hadoop-Cenh RGW file system module; s2, constructing a transmission interface and performing adaptation; s3, creating a class inheritance and realizing a FileSystem abstract class; s4, the Ceph RGW and the Delta Lake are connected through an adaptive interface; and S5, performing access and systematization operation on the data stored in the Ceph RGW storage warehouse through a FileSystem abstract class. The method has the advantages that the working efficiency is effectively improved, and the hardware cost is reduced.

Deployment method and device for chip storage requirements, equipment and storage medium

The embodiment of the invention discloses a chip storage demand deployment method and device, equipment and a storage medium. According to the method, under the condition that the performance of a preset array is not changed, namely a first data access mode is kept unchanged, an access result obtained on the basis of the first access mode is converted into an access result corresponding to a second data access mode by utilizing an association relationship between the first data access mode and the second data access mode; the data access precision of the second data access mode is higher than the data access precision of the first data access mode, so that the accuracy of the converted access result is higher, the accuracy of the deployment result is improved, and the deployment efficiency is improved. And the deployed chip can better meet the requirements of a hardware architecture, so that the design time of the hardware architecture is saved.
