Abstract: A machine vision-based sheet defect labeling method and apparatus, a device and a medium are provided. The method includes: performing a defect inspection on a target sheet conveyed to a preset defect inspection position, specifically, the target sheet continues to be conveyed towards a preset labeling position after passing the preset defect inspection position by being conveyed; generating a defect label of the target sheet when a defect present in the target sheet is determined, specifically, the defect label carries defect information represented by a two-dimensional barcode symbol including discontinuous dots; and labeling the defect of the target sheet at the preset labeling position with the defect label of the target sheet.

Abstract: In one aspect, composite nanoparticles are provided. In some embodiments, a composite nanoparticle comprises a host matrix comprising A4BX6-ZYZ and ABX3-PYP inclusions dispersed within the host matrix of the composite nanoparticle, wherein A is an alkali metal, B is an element selected from the group consisting of transition metals, Group IVA elements and rare earth elements and X and Y are independently selected from Group VIIA elements, 0?z?6, and 0?p<3.

Abstract: Metadata may be stored in, and retrieved from, a scalable, fault-tolerant metadata service. In one example, metadata is divided into partitions, and each partition is served by one or more nodes. For each partition, a first one of the nodes may handle read and write requests, and the other nodes may handle read requests in the event that the first node is down or is experiencing high load. When a request is made with respect to metadata, a metadata server may identify a node, in the partition to which the metadata is assigned, to which the request is to be made. The entity that is making the request then contacts that node, and requests the read or write on the metadata. In a partition, metadata may be replicated between the first node and the other nodes using a log-based replication protocol.
