Abstract: Techniques manage a storage system. In accordance with certain techniques, respective response times of multiple storage devices associated with the storage system are obtained. An extent whose workload satisfies a predefined condition is selected as a source extent from multiple extents on a source storage device in response to a response time of the source storage device among the multiple storage devices being above a predefined threshold. A destination storage device is selected from the multiple storage devices, the destination storage device having a lower workload than the source storage device. Data on the source extent are moved to a free extent on the destination storage device. Additionally, a balance may be stricken between workloads of various storage devices in a resource pool, and then the overall response speed of the resource pool may be increased.

Abstract: The present disclosure relates to methods and systems for using elastocaloric materials in subterranean formations. A variety of downhole packages, for example, electronic packages and instrumentation packages, are utilized in subterranean formations during hydrocarbon exploration and production operations. Downhole packages are typically designed to operate below a maximum temperature. When a downhole package is placed in the subterranean formation, its temperature may increase as a result of the natural temperature of the subterranean formation in which it is being used. Additionally, many of these downhole packages used downhole generate heat during operation which may raise the temperature of the downhole package. Reaching or exceeding the maximum temperature of a downhole package may result in ineffective operation and/or complete destruction of the downhole package. As a result, the downhole package may need to be frequently replaced.

Abstract: A method and system of detecting abnormalities captured in a medical image are provided. A medical image is received having one or more lesions and one or more interferences. One or more convolution layers are applied to the medical image to create one or more feature maps, respectively.
