1.1 組織標本を使用する定量解析が抱える諸問題 組織標本の解析は定性的な所見から始まる.顕微鏡を用いた丁寧な観察によって初めて得られる検体の 大きさや分布,形態などについての詳細な情報は,全ての研究の基礎となるべき重要なものである.しか しながら,定性的なデータだけでは,統計学的な検討が難しく,結果が主観的なものになりやすい.この ため,生理的組織と病的組織の比較など,さらなる研究を行う際には,定量的なデータが必要になる.定 量解析の基本的な命題は,いかにして検体の正確な数を客観的に求めることができるか,ということであ る.組織標本に基づく定量解析は単純に思われるが,正確なデータを得ることは実は容易ではない. 最大の問題は,サンプリングバイアスである(図1).これは,標本抽出の際に母集団を代表していない 検体が選ばれるために生じる偏りのことであり,2次元的な切片を使って定量解析を行...

متن کاملIntroduction to clarithmetic II
The earlier paper " Introduction to clarithmetic I " constructed an axiomatic system of arithmetic based on computability logic, and proved its soundness and extensional completeness with respect to polynomial time computability. The present paper elaborates three additional sound and complete systems in the same style and sense: one for polynomial space computability, one for elementary recurs...
متن کاملIntroduction to Circuits , II
This article is the last in a series of four articles (preceded by [23,22,21]) about modelling circuits by many sorted algebras. The notion of a circuit computation is defined as a sequence of circuit states. For a state of a circuit the next state is given by executing operations at circuit vertices in the current state, according to denotations of the operations. The values at input vertices ...
متن کاملIntroduction to Volume Ii
The writings that have been collected in this volume are closely related to Wilhelm Dilthey’s efforts to complete the second volume of the Introduction to the Human Sciences. Dilthey himself pub lished the first volume (Books One and Two) of his Einleitung in die Geisteswissenschaften in 1883. He never completed Books Three to Six. Drafts for Books Four to Six did exist, but were only publishe...
