Abstract Backgrounds The single-pass long reads generated by third-generation sequencing technology exhibit a higher error rate. However, the circular consensus (CCS) produces shorter reads. Thus, it is effective to manage rate of algorithmically with help homologous high-precision and low-cost short from Next Generation Sequencing (NGS) technology. Methods In this work, hybrid correction method (NmTHC) based on generative neural machine translation model proposed automatically capture...

Image acquisition and transmission in wireless sensor networks (WSN) are core issues for some resource-deficient multimedia sensing applications. Reducing sampling rates data lowers node costs energy, addressing communication bottlenecks. Block compressed (BCS) can meet the above requirements. For BCS, sparsity or smoothness of block signal is a crucial parameter, which determines setting range rate. side node, we cannot directly obtain complete digital signal. Therefore, it becomes...

After 1895 as the Manchu monarchy failed to deal with national crisis created by China's loss in first Sino–Japanese War, ideology of revolution won a foothold. A paradigm shift Chinese revolutionary discourse, radicalized way Japanese translations and symbolized Sun Yat-sen's self-proclaimed “revolutionary party,” embraced view rising masses masters history. It was during age world that Kang Youwei shaped his worldview. While juxtaposing French Revolution anti-Manchu revolution, he betrayed...

We report the experiments on using fuzzy clustering method for control system design. compare, in context of inverted pendulum problem, "exact" surface generated by numerical integration and modeled rules a controller. The are obtained applying to small random set learning points from exact surface. Small difference between surface, mostly less than 1%, indicates that is capable capturing essence inherently nonlinear unstable only set. controller also tested through simulation. results...

A stable 10 GHz pedestal-free short pulse generation scheme consisting of cascaded commercial LiNbO(3) modulators has been proposed and successfully demonstrated experimentally. Fiber-based compression reshaping stages have utilized to obtain a 1.38 ps optical train with very little pedestal 132 fs timing jitter. Excellent performance multiplexing from Gbits/s 160 using this method indicates good potential for application in ultrahigh-speed time-division-multiplexing systems.
