Abstract: Provided are immunoconjugate probes useful for detecting hepatocellular carcinoma (HCC) lesions. The probes comprise a glypican-3 (GPC3)-specific monoclonal antibody or fragment thereof conjugated to a radionuclide such as 89Zr, 64Cu, and the like. The probes are useful for obtaining PET images with high tumor-to-liver ratios and targeting for diagnostic imaging of HCC lesions or cells in vitro and in vivo.

Abstract: A method, computer program product, and computer system for disk management in a distributed storage system, the distributed storage system comprises a plurality of disks within a main disk ring, and store target data. In one embodiment, the method comprises dividing the target data into cold target data and hot target data, and grouping one or more disks within the main disk ring into a cold data disk ring and the remaining one or more disks within the main disk ring into a hot data disk ring. The method further comprises migrating the cold target data on disks not within the cold data disk ring onto disks within the cold data disk ring while migrating the hot target data on disks not within the hot data disk ring onto disks within the hot data disk ring, and reducing a spinning rate of disks within the cold data disk ring.

Abstract: A method, computer program product, and computer system are disclosed for disk management in a distributed storage system, wherein the distributed storage system comprises a plurality of disks within a main disk ring, and the disks store target data. In one embodiment, the method comprises dividing the target data into cold target data and hot target data, and grouping one or more disks within the main disk ring into a cold data disk ring and the remaining one or more disks within the main disk ring into a hot data disk ring, based on the cold target data's and the hot target data's positions on disks. The method further comprises migrating the cold target data on disks not within the cold data disk ring onto disks within the cold data disk ring while migrating the hot target data on disks not within the hot data disk ring onto disks within the hot data disk ring, and reducing a spinning rate of disks within the cold data disk ring.

Abstract: Provided are techniques for optimized content object storage service for large scale content. A content object file is created. An index entry for the content object file is created with a content object key and a content object location. The content object file is appended to an aggregated file on a storage node. In response to a request to retrieve the content object file from the aggregated file, the content object key is used to access the content object location that describes the storage node, a name of the aggregated file, an offset into the aggregated file, and a size of the content object file to retrieve the content object file.

Abstract: The invention provides a method and devices for disk management in distributed storage system, wherein the distributed storage system comprises a plurality of disks within a main disk ring, the disks store target data, the method comprising: dividing the target data into cold target data and hot target data; grouping on or more disks within the main disk ring into a cold data disk ring and the remaining one or more disks into a hot data disk ring, based on the cold target data's and the hot target data's positions on disks; migrating the cold target data on disks not within the cold data disk ring onto disks within the cold data disk ring while migrating the hot target data on disks not within the hot data disk ring onto disks within the hot data disk ring; and reducing spinning rates of disks within the cold data disk ring.

Abstract: A method and system for storage of an aggregation file and method and system for compression of the same. The method for compressing an aggregation file includes: acquiring the aggregation file to be compressed; copying remaining files in the acquired aggregation file into a new aggregation file based on metadata of a deleted object stored in a deletion file corresponding to the acquired aggregation file; and removing the acquired aggregation file. The present invention also provides a system for compressing an aggregation file and a method and system for storing an aggregation file.

Abstract: A latest status record of an object in a local storage node is obtained as a local status record of the object. The status record includes a name of an operation changing the object, a timestamp of the operation changing the object, a first status flag, and a second status flag. The first status flag indicates whether a synchronization of the object from current object storage node to another object storage node is executed. The second status flag indicates whether a synchronization of the object from another object storage node to the current object storage node is executed. The latest status record of the object is obtained of the object in from a remote object storage node as a remote status record of the object. A synchronization of the object is executed based on the local status record and the remote status record.
