Dictionary mechanism is the basis of Chinese word segmentation, and its quality directly affects the speed and efficiency of Chinese word segmentation. In existing dictionary mechanisms, there are such shortages as space wasting, low efficiency, and difficult maintenance, and therefore, how to establish an effective mechanism is an urgent problem for(More)
PLLA fibrous tissue scaffolds with controlled fiber nanoscale surface roughness are fabricated with a novel centrifugal jet spinning process. The centrifugal jet spinning technique is a highly efficient synthesis method for micron- to nano-sized fibers with a production rate up to 0.5 g min(-1). During the centrifugal jet spinning process, a polymer(More)
