—Now high-throughput sequencing technologies can yield a huge volume of sequence data with affordable price, the explosion rate of sequence data is outpacing the performance improvement of CPU, which means trivial sequence analysis task may challenge existing serial programs running purely on CPU. This paper depicts a highly parallel sequence translation(More)
This research is to investigate study the flavonoids from stems of Nelumbo nucifera and the cytotoxic activities of iso- lated compounds. The constituents were separated by column chromatography,and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for cytoxic activities by MTT method. Twelve compounds(More)
In this paper, the potential sensitivity in Kelvin probe force microscopy (KPFM) was investigated in frequency modulation (FM) and heterodyne amplitude modulation (AM) modes. We showed theoretically that the minimum detectable contact potential difference (CPD) in FM-KPFM is higher than in heterodyne AM-KPFM. We experimentally confirmed that the(More)
This study is to study is to investigate the coumarins from Fruit of Cnidium monnieri and their cytotoxic activities. The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for their cytoxic activities by MTT method. Eleven compounds were isolated(More)
