—It is important to use cache efficiently for the content deployment in the aspect of reducing load of server and latency, especially in content-oriented networks such as ICN (Information Centric Networking). Since the capacity of cache on each network node is limited, numbers of cache replacement algorithm have been proposed. However, because of previous(More)
To elucidate further the genetic mechanism underlying anthocyanin accumulation in the storage roots of recent Japanese purple-fleshed sweetpotato cultivars, we compared the structure of the IbMYB1 gene in cultivar Ayamurasaki and its spontaneous mutant, AYM96, whose storage roots do not accumulate anthocyanin. Amplification of the IbMYB1 genomic fragment(More)
To integer programming, a ideals have been problems, which Hiroshi Imai jases and standard pairs via toric ilgebraic approaches using Grobner k studied in recent years. In this paper, we consider a unimodular case, e.g., network flow enables us to analyze primal and dual problems in an equal setting. By combining existing results in an algebraic approach,(More)
