Cook's Theorem [Cormen, T.H., Leiserson, C.E., Rivest, R.L., 2001. Introduction to Algorithms, second ed., The MIT Press; Garey, M.R., Johnson, D.S., 1979. Computer and Intractability, Freeman, San Fransico, CA] is that if one algorithm for an NP-complete or an NP-hard problem will be developed, then other problems will be solved by means of reduction to that problem. Cook's Theorem has been de...

A correlation between diversity levels and rates of recombination is predicted both by models of positive selection, such as hitchhiking associated with the rapid fixation of advantageous mutations, and by models of purifying selection against strongly deleterious mutations (commonly referred to as "background selection"). With parameter values appropriate for Drosophila populations, only the f...

1 はじめに 並列計算機システムへの汎用性(マルチユーザ・ マルチジョブ)導入による保護機能の実現や実資源 の仮想化は並列処理性能の大幅な低下の原因となる ため、現状の並列計算環境および並列計算機は基本 的にバックエンドプロセッサとしてバッチ処理で使 用されることが多い。つまり、ソフトウェアによる 様々な最適化方式の適用および軽い通信同期手法が システムの独占的使用を要求し、システムの柔軟か つ汎用的な使用形態と相容れないのである。 このような状況を改善するため、我々は 1989年 よりすべての CPUから等距離でアクセス可能な 集中共有メモリを持つ Uniform Memory Access (UMA)型並列計算機を対象にして、ユーザによ る最適化を支援する汎用オペレーティングシステム 核 SS{CORE [1]を研究開発してきた。 SS{CORE の研究においては議論を単純化する...

j j j k z T z T z = = ∑ where T is a 2D similarity transformation. Proof: Similarity transformations can be represented using a linear polynomial over the complex plane in the following way. If the similarity transformation T consists of rotation by positive angle θ, uniform scale s and a translation t = tx + ity, then according to the rules of complex numbers: ( ) ( ) i T x iy T z se z t z θ +...

In their recent paper, Barker and Howell reviewed some of the more recent literature on the reliability and validity of the penile plethysmograph in the assessment of male sex offenders. Although Barker and Howell recognized that the test has not been standardized and that the results are susceptible to faking, they nevertheless maintained that the plethysmograph is useful in the evaluation and...
