Download or read book Diagram Groups written by Victor Guba and published by American Mathematical Soc.. This book was released on 1997 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagram groups are groups consisting of spherical diagrams (pictures) over monoid presentations. They can be also defined as fundamental groups of the Squier complexes associated with monoid presentations. The authors show that the class of diagram groups contains some well-known groups, such as the R. Thompson group F. This class is closed under free products, finite direct products, and some other group-theoretical operations. The authors develop combinatorics on diagrams similar to the combinatorics on words. This helps in finding some structure and algorithmic properties of diagram groups. Some of these properties are new even for R. Thompson's group F. In particular, the authors describe the centralizers of elements in F, prove that it has solvable conjugacy problems, etc.

Download or read book Catalytic Arylation Methods written by Anthony J. Burke and published by John Wiley & Sons. This book was released on 2015-02-09 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This "hands-on" approach to the topic of arylation consolidates the body of key research over the last ten years (and up to around 2014) on various catalytic methods which involve an arylation process. Clearly structured, the chapters in this one-stop resource are arranged according to the reaction type, and focus on novel, efficient and sustainable processes, rather than the well-known and established cross-coupling methods. The entire contents are written by two authors with academic and industrial expertise to ensure consistent coverage of the latest developments in the field, as well as industrial applications, such as C-H activation, iron and gold-catalyzed coupling reactions, cycloadditions or novel methodologies using arylboron reagents. A cross-section of relevant tried-and-tested experimental protocols is included at the end of each chapter for putting into immediate practice, along with patent literature. Due to its emphasis on efficient, "green" methods and industrial applications of the products concerned, this interdisciplinary text will be essential reading for synthetic chemists in both academia and industry, especially in medicinal and process chemistry.

Download or read book Directed Evolution of Selective Enzymes written by Manfred T. Reetz and published by John Wiley & Sons. This book was released on 2016-12-19 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authored by one of the world's leading organic chemists, this authoritative reference provides an overview of basic strategies in directed evolution and introduces common gene mutagenesis, screening and selection methods. Throughout the text, emphasis is placed on methodology development to maximize efficiency, reliability and speed of the experiments and to provide guidelines for efficient protein engineering. Professor Reetz highlights the application of directed evolution experiments to address limitations in the field of enzyme selectivity, substrate scope, activity and robustness. He critically reviews recent developments and case studies, takes a look at future applications in the field of organic synthesis, and concludes with lessons learned from previous experiments.

Download or read book Trafficking in Broken Hearts written by Edwin Sanchez and published by Broadway Play Publishing In. This book was released on 2014-12-15 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Papo, a tough-talking Puerto Rican hustler from the Bronx, meets Brian, a frightened young lawyer from the Midwest, Papo begins to glimpse the possibility of a romantic escape from his life on the streets. At the same time, Bobby, a 17-year-old runaway who has been repeatedly raped by his older brother, offers to take care of Papo and moves in with him in his fleabag hotel room. It is then when Papo suddenly finds his defenses melting and his heart torn in two directions. TRAFFICKING IN BROKEN HEARTS is a gritty, urban love story. "Playwright Edwin Sanchez makes a promising New York debut with TRAFFICKING IN BROKEN HEARTS, a grim, streetwise and bracingly compassionate work ... he convinces with the honesty of his writing and a canny, thoughtful grasp of his trio of characters. The playwright does an especially effective job in penning the gray shades of his characters ..." -Greg Evans, Variety
Download or read book Shape Theory written by J. M. Cordier and published by Courier Corporation. This book was released on 2013-12-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This in-depth treatment uses shape theory as a "case study" to illustrate situations common to many areas of mathematics, including the use of archetypal models as a basis for systems of approximations. It offers students a unified and consolidated presentation of extensive research from category theory, shape theory, and the study of topological algebras. A short introduction to geometric shape explains specifics of the construction of the shape category and relates it to an abstract definition of shape theory. Upon returning to the geometric base, the text considers simplical complexes and numerable covers, in addition to Morita's form of shape theory. Subsequent chapters explore Bénabou's theory of distributors, the theory of exact squares, Kan extensions, the notion of a stable object, and stability in an Abelian context. The text concludes with a brief description of derived functors of the limit functor theory—the concept that leads to movability and strong movability of systems—and illustrations of the equivalence of strong movability and stability in many contexts.

Download or read book Organometallic Chemistry and Catalysis written by Karl Kirchner and published by Springer Science & Business Media. This book was released on 2001-02-01 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the beginning of chemistry as an exact (natural) science - almost 200 years ago - there was a more or less distinct differentiation between its various branches such as organic, inorganic, physical, analytical, or biochemistry. With the increasing insight into the connections and governing laws it soon became obvious, however, that such a clear separation could be regarded as more or less obsolete; within almost any field of chemical research one has to deal with most of the branches mentioned. Especially organic and inorganic chemistry are significant examples for this statement, overlapping considerably within the important field of organome tallic chemistry. This regime of chemistry started its advance with the discovery of dimethylzinc 150 years ago, had a highlight with the introduction of Grignard reagents around 1900, developed further with the start of lithium organyls in 1925 and literally exploded after the discovery of the first transition metal cyclopenta dienyl complex ferrocene half a century ago. The chronological sequence of the important steps, i. e. 1850 (Zn) - 1900 (Mg) - 1925 (Li) - 1950 (Fe), seems rather remarkable. The increasing group of metallocenes is not only of high theoretical and, due to the potential chirality of its members, stereochemical interest, but offers also a wide variety of extremely useful catalysts, especially for stereoselective reactions. The Austrian Chemical Society took this development into account by organizing the Twelfth International Conference on Organometallic Chemistry held in Vienna in 1985.
Download or read book Artificial Intelligence and Natural Language Processing written by Sudhir K. Mishra and published by . This book was released on 2018-04 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial Intelligence and Natural Language Processing is designed for students of computer science and linguistics at graduate and post-graduate levels, who have an interest in Natural Language Processing (NLP). This book balances the theoretical aspects of computer science and linguistics with their applications in NLP, keeping in mind the background of the students from either direction. Theories of linguistics such as phonology, morphology, syntax, semantics and lexicography are covered in the first section of the book. In the second, focus is given to theoretical aspects of computer science including AI, concepts of probability theory and approaches of machine learning. These two parts will provide students with the foundations of the field. The third part discusses the applications/tasks of NLP covering the areas of machine translation (MT) and grammar formalism in an Indian Language scenario, as well as speech processing.
