Late Transition Metal-Carboryne Complexes

by Zaozao Qiu

Zaozao Qiu shows in this thesis that transition metals can mediate or catalyze the cycloaddition or coupling reactions of carboryne with alkynes or alkenes to afford benzocarboranes, alkenylcarboranes or dihydrobenzocarboranes. These results represent powerful strategies to assemble useful complex molecules from very simple precursors in a single operation. Carboranes have many applications in medicine. However, their unique structures make derivatization difficult and the limited efficient synthetic methods to obtain functional carborane materials have restricted applications of carboranes within a narrow scope. This work breaks a new ground in metal-carboryne chemistry and will have a significant impact on synthetic, cluster and materials chemistry.

Im Fokus: Entdecker

by Nadja Podbregar Dieter Lohmann

Während es heute auf der Landkarte unserer Erde kaum noch weißen Flecken gibt, waren im 13. Jahrhundert weite Teile "Terra incognita". Licht ins Dunkel brachten erst die Entdecker und Seefahrer - angetrieben von Forschergeist und vom Streben nach Macht und Reichtum. In dem Buch werden auf ebenso spannende wie amüsante Weise ihre wichtigsten Stationen geschildert: Leser begleiten Marco Polo ins alte China und Magellan, als er zum ersten Mal die Welt umsegelt; Kolumbus bei der (Wieder-)Entdeckung Amerikas und Robert Peary beim Wettlauf zum Nordpol.

Economics and the Interpretation and Application of U.S. and E.U. Antitrust Law: Volume II

by Richard S. Markovits

Volume 2 uses the economic and legal concepts/theories of Volume 1 to (1) analyze the U.S. and E.U. antitrust legality of mergers, joint ventures, and the pricing-technique and contractual/sales-policy distributor-control surrogates for vertical integration and (2) assess related positions of scholars and U.S. and E.U. antitrust officials. Its analysis of horizontal mergers (1) delineates non-market-oriented protocols for determining whether they manifest specific anticompetitive intent, would lessen competition, or are rendered lawful by the efficiencies they would generate, (2) criticizes the U.S. courts’ traditional market-share/market-concentration protocol, the HHI-oriented protocols of the 1992 U.S. DOJ/FTC Guidelines and the European Commission (EC) Guidelines, and the various non-market-oriented protocols the DOJ/FTC have increasingly been using, (3) argues that, although the 2010 U.S. Guidelines and DOJ/FTC officials discuss market definition as if it matters, those Guidelines actually reject market-oriented approaches, and (4) reviews the relevant U.S. and E.U. case-law. Its analysis of conglomerate mergers (1) shows that they can perform the same legitimate and competition-increasing functions as horizontal mergers and can yield illegitimate profits and lessen competition by increasing contrived oligopolistic pricing and retaliation barriers to investment, (2) analyzes the determinants of all these effects, and (3) assesses limit-price theory, the toe-hold-merger doctrine, and U.S. and E.U. case-law. Its analysis of vertical conduct (1) examines the legitimate functions of each type of such conduct, (2) delineates the conditions under which each manifests specific anticompetitive intent and/or lessens competition, and (3) assesses related U.S. and E.U. case-law and DOJ/FTC and EC positions. Its analysis of joint ventures (1) explains that they violate U.S. law only when they manifest specific anticompetitive intent while they violate E.U. law either for this reason or because they lessen competition, (2) discusses the meaning of an “ancillary restraint” and demonstrates that whether a joint-venture agreement would be illegal if it imposed no restraints and whether any restraints imposed are ancillary can be determined only through case-by-case analysis, (3) explains why scholars and officials overestimate the economic efficiency of R&D joint ventures, and (4) discusses related U.S. and E.U. case-law and DOJ/FTC and EC positions. The study’s Conclusion (1) reviews how its analyses justify its innovative conceptual systems and (2) compares U.S. and E.U. antitrust law as written and as applied.

Economics and the Interpretation and Application of U.S. and E.U. Antitrust Law: Volume I

by Richard S. Markovits

This volume (1) defines the specific-anticompetitive-intent, lessening-competition, distorting-competition, and exploitative-abuse tests of illegality promulgated by U.S. and/or E.U. antitrust law, (2) compares the efficiency defenses promulgated by U.S. and E.U. antitrust law, (3) compares the conduct-coverage of the various U.S. and E.U. antitrust laws, (4) defines price competition and quality-or-variety-increasing-investment (QV-investment) competition and explains why they should be analyzed separately, (5) defines the components of individualized-pricing and across-the-board-pricing sellers’ price minus marginal cost gaps and analyses each’s determinants, (6) defines the determinants of the intensity of QV-investment competition and explains how they determine that intensity, (7) demonstrates that definitions of both classical and antitrust markets are inevitably arbitrary, not just at their periphery but comprehensively, (8) criticizes the various protocols for market definition recommended/used by scholars, the U.S. antitrust agencies, the European Commission, and U.S. and E.U. courts, (9) explains that a firm’s economic (market) power or dominance depends on its power over both price and QV investment and demonstrates that, even if markets could be defined non-arbitrarily, a firm’s economic power could not be predicted from its market share, (10) articulates a definition of “oligopolistic conduct” that some economists have implicitly used–conduct whose perpetrator-perceived ex ante profitability depended critically on the perpetrator’s belief that its rivals’ responses would be affected by their belief that it could react to their responses, distinguishes two types of such conduct–contrived and natural–by whether it entails anticompetitive threats and/or offers, explains why this distinction is critical under U.S. but not E.U. antitrust law, analyzes the profitability of each kind of oligopolistic conduct, examines these analyses’ implications for each’s antitrust legality, and criticizes related U.S. and E.U. case-law and doctrine and scholarly positions (e.g., on the evidence that establishes the illegal oligopolistic character of pricing), and (11) executes parallel analyses of predatory conduct--e.g., criticizes various arguments for the inevitable unprofitability of predatory pricing, the various tests that economists/U.S. courts advocate using/use to determine whether pricing is predatory, and two analyses by economists of the conditions under which QV investment and systems rivalry are predatory and examines the conditions under which production-process research, plant-modernization, and long-term full-requirements contracts are predatory.

Notch Regulation of the Immune System

by Freddy Radtke

Notch signaling regulates many cell fate decision and differentiation processes during embryonic development and tissue homeostasis. Moreover, disregulation of the pathway is associated with human disorders and cancer. In the last 15 years it became evident that Notch plays important roles in the hematopoietic system as well as in the regulation of immune responses. This special issue on Notch regulation of the immune system summarizes recent advances and covers multiple aspects of Notch signaling within the hematopoietic and the immune system. This issue covers subjects including Notch function in embryonic and adult hematopoietic stem cells, lymphocyte development and function as well as in T cell leukemia.

Software Process Definition and Management

by Martin Kowalczyk Jürgen Münch Martín Soto Ove Armbrust

The concept of processes is at the heart of software and systems engineering. Software process models integrate software engineering methods and techniques and are the basis for managing large-scale software and IT projects. High product quality routinely results from high process quality. Software process management deals with getting and maintaining control over processes and their evolution. Becoming acquainted with existing software process models is not enough, though. It is important to understand how to select, define, manage, deploy, evaluate, and systematically evolve software process models so that they suitably address the problems, applications, and environments to which they are applied. Providing basic knowledge for these important tasks is the main goal of this textbook. Münch and his co-authors aim at providing knowledge that enables readers to develop useful process models that are suitable for their own purposes. They start with the basic concepts. Subsequently, existing representative process models are introduced, followed by a description of how to create individual models and the necessary means for doing so (i.e., notations and tools). Lastly, different possible usage scenarios for process management are highlighted (e.g. process improvement and software process simulation). Their book is aimed at students and researchers working on software project management, software quality assurance, and software measurement; and at practitioners who are interested in process definition and management for developing, maintaining, and operating software-intensive systems and services.

Nuclear Physics with Polarized Particles

by Hans Paetz gen. Schieck

The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory--a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear reactions. The book concludes with a brief review of modern applications in medicine and fusion energy research. For reasons of conciseness and of the pedagogical aims of this volume, examples are mainly taken from low-energy installations such as tandem Van de Graaff laboratories, although the emphasis of present research is shifting to medium- and high-energy nuclear physics. Consequently, this volume is restricted to describing non-relativistic processes and focuses on the energy range from astrophysical energies (a few keV) to tens of MeV. It is further restricted to polarimetry of hadronic particles.

Engineering Production Control Strategies

by Christoph Karrer

Identifying and customizing suitable control strategies is a challenging task, especially when production systems have to cope with variable demands, forecast error, and unstable processes. The focus of this book lies on helping companies with complex and discrete production systems to tailor a production control strategy to their needs. Thereby, the mutual merits of "push" and "pull" systems are taken into account, leading to hybrid strategies. Consequently, the book addresses practitioners who are interested in looking behind the scenes and into the physics of production control. A real-life case study demonstrates the practical applicability of the presented framework.

Studying Atomic Dynamics with Coherent X-rays

by Michael Leitner

Diffusion in solids at moderate temperatures is a well-known phenomenon. However, direct experimental evidence about the responsible atomic-scale mechanisms has been scarce, due to difficulties in probing the relevant length- and time-scales. The present thesis deals with the application of X-ray Photon Correlation Spectroscopy (XPCS) for answering such questions. This is an established method for the study of slow dynamics on length-scales of a few nanometres. The scattered intensity in the diffuse regime, i.e. corresponding to atomic distances, is very low, however, and so it has so far been considered impossible to use XPCS for this problem. Threefold progress is reported in this work: It proposes a number of systems selected for high diffuse intensity, it optimizes the photon detection and data evaluation procedures, and it establishes theoretical models for interpretating the results. Together these advances allowed the first successful atomic-scale XPCS experiment, which elucidated the role of preferred configurations for atomic jumps in a copper-gold alloy. The growth in available coherent X-ray intensity together with next-generation X-ray sources will open up a wide field of application for this new method.

Quantum Entanglement in Electron Optics

by Rama Ghosh Naresh Chandra

This monograph forms an interdisciplinary study in atomic, molecular, and quantum information (QI) science. Here a reader will find that applications of the tools developed in QI provide new physical insights into electron optics as well as properties of atoms & molecules which, in turn, are useful in studying QI both at fundamental and applied levels. In particular, this book investigates entanglement properties of flying electronic qubits generated in some of the well known processes capable of taking place in an atom or a molecule following the absorption of a photon. Here, one can generate Coulombic or fine-structure entanglement of electronic qubits. The properties of these entanglements differ not only from each other, but also from those when spin of an inner-shell photoelectron is entangled with the polarization of the subsequent fluorescence. Spins of an outer-shell electron and of a residual photoion can have free or bound entanglement in a laboratory.
