Cloud storage systems take advantage of distributed storage technology and virtualization technology, to provide virtual machine clients with customizable storage service. They can be divided into two types: distributed file system and block level storage system. Orthrus is a Light weighted Block-Level Cloud Storage System, which adopt multiple volume(More)
We established a red callus from the leaves of a red-fleshed apple individual, which was a hybrid offspring of the cross between Malus sieversii f. niedzwetzkyana and Malus domestica cv. ‘Fuji’. We analyzed callus growth and anthocyanin biosynthesis/metabolism under different combinations of temperature and light conditions. Incubation in darkness resulted(More)
Taking advantage of distributed storage technology and virtualization technology, cloud storage systems provide virtual machine clients customizable storage service. They can be divided into two types: distributed file system and block level storage system. There are two disadvantages in existing block level storage system: Firstly, Some of them are tightly(More)
We demonstrate the optical orbital angular momentum conservation during the transfer process from subwavelength plasmonic vortex lens (PVLs) to light and the generating process of surface plasmon polaritons (SPPs). Illuminating plasmonic vortex lenses with beams carrying optical orbital angular momentum, the SP vortices with orbital angular momentum were(More)
This study analyzes the duration and division of the flood season in the Fenhe River Basin over the period of 1957–2014 based on daily precipitation data collected from 14 meteorological stations. The Mann–Kendall detection, the multiscale moving t-test, and the Fisher optimal partition methods are used to evaluate the impact of climate change on flood(More)
AC bridge techniques commonly used for precision impedance measurements have been adapted to develop an eddy current sensor for rail defect detection. By using two detection coils instead of just one as in a conventional sensor, we can balance out the large baseline signals corresponding to a normal rail. We have significantly enhanced the detection(More)
