Fuzzy logic has become an important tool for a number of different applications ranging from the control of engineering systems to artificial intelligence. In this concise introduction, the author presents a succinct guide to the basic ideas of fuzzy logic, fuzzy sets, fuzzy relations, and fuzzy reasoning, and shows how they may be applied. The book culminates in a chapter which describes fuzzy logic control: the design of intelligent control systems using fuzzy if-then rules which make use of human knowledge (...) and experience to behave in a manner similar to a human controller. Throughout, the level of mathematical knowledge required is kept basic and the concepts are illustrated with numerous diagrams to aid in comprehension. As a result, all those curious to know more about fuzzy concepts and their real-world application will find this a good place to start. (shrink)

Molecular and biochemical analysis of the biogenesis of peroxisomes has made rapid progress in recent years. Research on the mechanism of targeting of peroxisomal proteins has revealed that many, but not all, peroxisomal proteins have a conserved tripeptide motif in their carboxy‐terminal portions which is required for entry into peroxisomes; the topogenic signal mechanism thus differs in these instances from those employed in mitochondria and endoplasmic reticulum. Other factors involved in peroxisome biogenesis are also coming to light.

The Common Anatomy Reference Ontology (CARO) is being developed to facilitate interoperability between existing anatomy ontologies for different species, and will provide a template for building new anatomy ontologies. CARO has a structural axis of classification based on the top-level nodes of the Foundational Model of Anatomy. CARO will complement the developmental process sub-ontology of the GO Biological Process ontology, using it to ensure the coherent treatment of developmental stages, and to provide a common framework for the model organism communities (...) to classify developmental structures. Definitions for the types and relationships are being generated by a consortium of investigators from diverse backgrounds to ensure applicability to all organisms. CARO will support the coordination of cross-species ontologies at all levels of anatomical granularity by cross-referencing types within the cell type ontology (CL) and the Gene Ontology (GO) Cellular Component ontology. A complete cross-species CARO could be utilized in other ontologies for cross-product generation. (shrink)

解きやすい離散最適化問題に対して統一的な枠組を与える「離散凸解析」の全体像を平易に解説.

We consider a spatial bargaining model where players collectively choose a facility location on a two-dimensional rectilinear distance space through bargaining using the unanimity rule. We show that as players become infinitely patient, their stationary subgame perfect equilibrium utilities converge to the utilities that satisfy the lexicographic maximin utility criterion introduced by Sen.

本書は、生活者のハピネス(豊かさや幸せ)の視点から科学技術や社会の変革を考える『因果関係から相関へ、個別技術からシステムへ』と題した『武田シンポジウム2018』の内容をまとめたものです。昨今最も注目を 浴びている科学技術である「AI」、「免疫システム研究」、「民間宇宙ロケット開発」の3つと異なる切り口から、ビッグデータと言われる時代の科学の方法論、個の集積以上の意味をもつシステムとしてのアプローチに ついて立体的に考察します。.
