Biomanipulation has been employed in numerous locations throughout the world as a means for reducing phytoplankton biomass; however, it has not been employed very often in Japan. A common approach involves the introduction of piscivorous fish to reduce the abundance of planktivorous fish. In our study, to first apply biomanipulation, we stocked Lake(More)
The idea of combining the network of HMMs and the dynamic programming-based search is highly relevant to online handwriting recognition. The word model of HMM network can be systematically constructed by concatenating letter and ligature HMM's while sharing common ones. Character recognition in such a network can be defined as the task of best aligning a(More)
A number of risk assessments of the adverse effects of Cu and its compounds have been conducted since it is one of the leading substances responsible for water contamination. However, with the exception of standard organisms, ecotoxicological knowledge is still scarce. Here, we examined the influence of Ca2+ and Mg2+ concentrations on acute toxicity of Cu(More)
Understanding functional roles of prey defense in biological interactions remains a major task in food web ecology. We investigated the role of an inducible defense as a factor that influences the trophic pathway in an aquatic food web. Quantitative information on food web structure in Lake Suwa (a eutrophic lake in Japan) was provided by carbon and(More)
—A critical weak point of Solid State Drives (SSDs) is the limited lifespan which stems from the characteristics of NAND flash memory. In this paper, we propose a new deduplication scheme called block-level content-aware chunking to extend the lifetime of SSDs. The proposed scheme divides the data within a fixed-size block into a set of variable-sized(More)
