Tumor-containing CEA in Colon Cancers

Carcinoembryonic antigen (CEA) in serum and fresh cancer tissue taken at surgery was measured and analyzed in terms of the disease stage. The CEA level in serum (s-CEA ) has become higher with advance in the disease stage. However, in stage V it was lowered as well as CEA level in cancer mass (ca-CEA). It is suggested that S-CEA is influenced by cancer invasion into the vessel wall, tumor necrosis and/or degeneration which ca-CEA may well be migrated from the tumor cells

Development of Special Purpose Processor for Molecular Orbital Calculations

筆者らは,非経験的分子軌道計算を高速に処理する専用並列計算機システムに搭載する,二電子積分計算専用プロセッサ,Ericの開発を行っている.二電子積分計算のアルゴリズムとして採用する小原のアルゴリズムの特徴を活かすことで高速処理が可能となる.本稿では,Ericの全体構成および動作について述べる.そして,現段階でのEricの性能評価を行う.We are developing Eric which is a special-purpose processor built in special-purpose computer system for ab initio Molecular orbital calculations to reduce the calculation time. Using characterization of two-electron integrals in the \u22Obara method,\u22 it is possible to reduce the calculation time. In this paper, we describe outline and operation of Eric for Molecular orbital Calculations. Also, we evaluate the performance of Eric
