This second edition is a corrected and extended version of the first. It is a textbook for students, as well as a reference book for the working mathematician, on cohomological topics in number theory. In all it is a virtually complete treatment of a vast array of central topics in algebraic number theory. New material is introduced here on duality theorems for unramified and tamely ramified extensions as well as a careful analysis of 2-extensions of real number fields.

Understanding Complex Urban Systems takes as its point of departure the insight that the challenges of global urbanization and the complexity of urban systems cannot be understood - let alone 'managed' - by sectoral and disciplinary approaches alone. But while there has recently been significant progress in broadening and refining the methodologies for the quantitative modeling of complex urban systems, in deepening the theoretical understanding of cities as complex systems, or in illuminating the implications for urban planning, there is still a lack of well-founded conceptual thinking on the methodological foundations and the strategies of modeling urban complexity across the disciplines. Bringing together experts from the fields of urban and spatial planning, ecology, urban geography, real estate analysis, organizational cybernetics, stochastic optimization, and literary studies, as well as specialists in various systems approaches and in transdisciplinary methodologies of urban analysis, the volume seeks to advance the discussion on multidisciplinary approaches to urban modeling. While engaging with the 'state of the art' in their respective fields, the contributions are specifically written for both experts from a broad range of disciplines as well as for urban practitioners who feel the need for new approaches given the uncertainty of current developments.

Various applications in the field of pulmonary image analysis require a registration of CT images of the lung. For example, a registration-based estimation of the breathing motion is employed to increase the accuracy of dose distribution in radiotherapy. Alexander Schmidt-Richberg develops methods to explicitly model morphological and physiological knowledge about respiration in algorithms for the registration of thoracic CT images. The author focusses on two lung-specific issues: on the one hand, the alignment of the interlobular fissures and on the other hand, the estimation of sliding motion at the lung boundaries. He shows that by explicitly considering these aspects based on a segmentation of the respective structure, registration accuracy can be significantly improved.

The present manuscript is an improved edition of a text that first appeared under the same title in Bonner Mathematische Schriften, no.26, and originated from a series of lectures given by the author in 1965/66 in Wolfgang Krull's seminar in Bonn. Its main goal is to provide the reader, acquainted with the basics of algebraic number theory, a quick and immediate access to class field theory. This script consists of three parts, the first of which discusses the cohomology of finite groups. The second part discusses local class field theory, and the third part concerns the class field theory of finite algebraic number fields.

Volume 2 of massive work by a leading Shakespeare scholar and lexicographer, a standard in the field, provides full definitions, locations, and shades of meaning in every word in Shakespeare's plays and poems. The two volumes contain more than 50,000 exact quotations, each precisely located. There is no other word dictionary comparable to this work.

This book constitutes the proceedings of the Second International Workshop on Thoracic Image Analysis, TIA 2020, held in Lima, Peru, in October 2020. Due to COVID-19 pandemic the conference was held virtually. COVID-19 infection has brought a lot of attention to lung imaging and the role of CT imaging in the diagnostic workflow of COVID-19 suspects is an important topic. The 14 full papers presented deal with all aspects of image analysis of thoracic data, including: image acquisition and reconstruction, segmentation, registration, quantification, visualization, validation, population-based modeling, biophysical modeling (computational anatomy), deep learning, image analysis in small animals, outcome-based research and novel infectious disease applications.

Still often used today, German schoolmaster and philologist ALEXANDER SCHMIDT's (1816-1887) Shakespeare Lexicon is the source for elucidating the sometimes cryptic language of Shakespeare and tracking down quotations. Volume 1 covers A through L, from "a: the first letter of the alphabet" to "Lysimachus," a proper name. Every word from every play and poem is cataloged, referenced, and defined in this exhaustive two-volume work, the result of arduous research and stalwart dedication. Serious scholars and zealous fans will find the Lexicon the ultimate guide to reading and decoding the Bard.

Die vorliegende Festschrift wurdigt die wissenschaftliche Karriere von Hans-Jurgen Andress, wahrend der er die Methodenentwicklung im Bereich langsschnittlicher Analysemethoden gepragt und einflussreiche empirische Studien zu Armut, Ungleichheit und den Folgen kritischer Lebensereignisse vorgelegt hat. Der Band vereint nun diese Aspekte und versammelt empirische Studien, welche auf Basis langsschnittlicher analytischer Designs verschiedene Formen sozialer Ungleichheit in Deutschland untersuchen. In unterschiedlichen thematischen Feldern erarbeiten die Beitrage Erklarungen fur Ungleichheitspositionen und untersuchen insbesondere deren Einbettung in den Lebensverlauf. Neben ihrem konkreten empirischen Forschungsbeitrag demonstrieren die Studien damit gleichzeitig die analytischen Potentiale langsschnittlicher Designs und der vorhandenen langsschnittlichen Dateninfrastruktur in Deutschland. Die Herausgeber Prof. Dr. Marco Giesselmann ist Juniorprofessor an der Universitat Bielefeld und Mitarbeiter des DIW Berlin.Prof. Dr. Katrin Golsch ist Professorin fur Quantitative Methoden der empirischen Sozialforschung und Sozialstrukturanalyse am Institut fur Sozialwissenschaften der Universitat Osnabruck.Prof. Dr. Henning Lohmann ist Professur fur Soziologie am Fachbereich Sozialoekonomie der Universitat Hamburg.Dr. Alexander Schmidt-Catran ist akademischer Rat am Institut fur Soziologie und Sozialpsychologie (ISS) an der Universitat zu Koeln.

Der Klassiker zum Thema bietet Lesern, die mit den Grundlagen der algebraischen Zahlentheorie vertraut sind, einen raschen Zugang zur Klassenkoerpertheorie. Die Neuauflage ist eine verbesserte Version des 1969 in der Reihe B. I.-Hochschulskripten (Bibliographisches Institut Mannheim) erschienenen gleichnamigen Bandes. Das Werk besteht aus drei Teilen: Im ersten wird die Kohomologie der endlichen Gruppen behandelt, im zweiten die lokale Klassenkoerpertheorie, der dritte Teil widmet sich der Klassenkoerpertheorie der endlichen algebraischen Zahlkoerper.
