Gastroösophageale Refluxerkrankung: Differentialdiagnostik und Therapie
by Ahmed Madisch Joachim LabenzIn diesem Praxisbuch haben Experten auf diesem Gebiet das aktuelle Wissen zur Differenzialdiagnostik und zur Therapie - konservativ bis operativ - zusammengefasst.Das klinische Bild der Refluxkrankheit ist sehr vielfältig. Neben den klassischen Symptomen Sodbrennen und Schmerz hinter dem Brustbein können auch atypische Beschwerden wie Asthma, chronischerer Husten und Heiserkeit als Folge der Refluxerkrankung auftreten. Im schlimmsten Fall kann sich auch als Folge eines langjährigen Refluxes Speiseröhrenkrebs bilden. Insbesondere bei atypischen Symptomen ist aber die Diagnostik erschwert. Hier muss die klinische Expertise durch differenzierten Einsatz von apparativer Diagnostik ergänzt werden. Dieses Praxisbuch leistet eine Hilfestellung in der Funktionsdiagnostik und erläutert mögliche Diagnoseverfahren. Im Therapieteil werden konservative wie auch operative Optionen mit notwendigen Indikationen aufgezeigt. Kapitel zu den Besonderheiten bei Kindern mit Reflux und einem Auftreten bestimmter Symptome während der Schwangerschaft runden das Buch ab. Die Inhalte orientieren sich an der aktualisierten Leitlinie „Gastroösophageale Refluxkrankheit“.Neben der hohen Prävalenz und der deutlichen Einschränkung der Lebensqualität liegt die Bedeutung der Erkrankung im breiten klinischen Spektrum an Symptomen, Komplikationen und Folgeerkrankungen mit Relevanz für zahlreiche Fachdisziplinen auch außerhalb der Gastroenterologie. So bietet dieses Buch einen kompakten Wissenstranfer zum Krankheitsbild - nicht nur für Gastroenterologen.
Gated Communities and the Digital Polis: Rethinking Subjectivity, Reality, Exclusion, and Cooperation in an Urban Future (Advances in 21st Century Human Settlements)
by Kon Kim Heewon ChungThis edited collection provides an alternative discourse on cities evolving with physically and virtually networked communities—the ‘digital polis’—and offers a variety of perspectives from the humanities, media studies, geography, architecture, and urban studies. As an emergent concept that encompasses research and practice, the digital polis is oriented toward a counter-mapping of the digital cityscape beyond policing and gatekeeping in physical and virtual gated communities. Considering the digital polis as offering potential for active support of socially just and politically inclusive urban circumstances in ways that mirror the Greek polis, our attention is drawn towards the interweaving of the development of digital technology, urban space, and social dynamics. The four parts of this book address the formation of technosocial subjectivity, real-and-virtual combined urbanity, the spatial dimensions of digital exclusion and inclusion, and the prospect of emancipatory and empowering digital citizens. Individual chapters cover varied topics on digital feminism, data activism, networked individualism, digital commons, real-virtual communalism, the post-family imagination, digital fortress cities, rights to the smart city, online foodscapes, and open-source urbanism across the globe. Contributors explore the following questions: what developments can be found over recent decades in both physical and virtual communities such as cyberspace, and what will our urban future be like? What is the ‘digital polis’ and what kinds of new subjectivity does it produce? How does digital technology, as well as its virtuality, reshape the city and our spatial awareness of it? What kinds of exclusion and cooperation are at work in communities and spaces in the digital age? Each chapter responds to these questions in its own way, navigating readers through routes toward the digital polis.Chapter "Introduction - The digital polis and its practices: Beyond gated communities" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Gateway to the Heavens: How Geometric Shapes, Patterns and Symbols Form Our Reality (Gateway Series #1)
by Karen L. FrenchSimple geometric shapes and symbols combine to make the universal, powerful, sacred model Karen French calls Gateway to the Heavens. In this book, French explains the meaning and purpose of these shapes, how they mold our reality and perception of it and how they have a direct bearing on what you are and why you are here. These shapes and symbols contain messages that have been consistently represented in religion, philosophy, mythology, mysticism, the arts and sciences. Their messages are built into our genetic make-up and we recogniZe them instinctively. The book is divided up into 3 parts. Part 1 covers the properties of the basic geometric shapes and numbers. Part 2 describes how these, in turn, form layers of construction, creating principals that are fundamental to the purpose of the universe; the spiral sustains reality, the cross highlighting the central point of existence and the heart is where we weigh up our choices. Part 3 describes how we can use these principals to create positive change in our lives by helping us to expand our awareness of reality.

Gauge Field Theories: 100 Years After General Relativity
by Gunter ScharfOne of the main problems of theoretical physics concerns the unification of gravity with quantum theory. This monograph examines unification by means of the appropriate formulation of quantum gauge invariance. Suitable for advanced undergraduates and graduate students of physics, the treatment requires a basic knowledge of quantum mechanics.Opening chapters introduce the free quantum fields and prepare the field for the gauge structure, describing the inductive construction of the time-ordered products by causal perturbation theory. The analysis of causal gauge invariance follows, with considerations of massless and massive spin-1 gauge fields. Succeeding chapters explore the construction of spin-2 gauge theories, concluding with an examination of nongeometric general relativity that offers an innovate approach to gravity and cosmology.

Gauge Invariance Approach to Acoustic Fields
by Woon Siong GanThis book highlights the symmetry properties of acoustic fields and describes the gauge invariance approach, which can be used to reveal those properties. Symmetry is the key theoretical framework of metamaterials, as has been demonstrated by the successful fabrication of acoustical metamaterials. The book first provides the necessary theoretical background, which includes the covariant derivative, the vector potential, and invariance in coordinate transformation. This is followed by descriptions of global gauge invariance (isotropy), and of local gauge invariance (anisotropy). Sections on time reversal symmetry, reflection invariance, and invariance of finite amplitude waves round out the coverage.
Gauge Invariance and Weyl-polymer Quantization
by Franco StrocchiThe book gives an introduction to Weyl non-regular quantization suitable for the description of physically interesting quantum systems, where the traditional Dirac-Heisenberg quantization is not applicable. The latter implicitly assumes that the canonical variables describe observables, entailing necessarily the regularity of their exponentials (Weyl operators). However, in physically interesting cases -- typically in the presence of a gauge symmetry -- non-observable canonical variables are introduced for the description of the states, namely of the relevant representations of the observable algebra. In general, a gauge invariant ground state defines a non-regular representation of the gauge dependent Weyl operators, providing a mathematically consistent treatment of familiar quantum systems -- such as the electron in a periodic potential (Bloch electron), the Quantum Hall electron, or the quantum particle on a circle -- where the gauge transformations are, respectively, the lattice translations, the magnetic translations and the rotations of 2π. Relevant examples are also provided by quantum gauge field theory models, in particular by the temporal gauge of Quantum Electrodynamics, avoiding the conflict between the Gauss law constraint and the Dirac-Heisenberg canonical quantization. The same applies to Quantum Chromodynamics, where the non-regular quantization of the temporal gauge provides a simple solution of the U(1) problem and a simple link between the vacuum structure and the topology of the gauge group. Last but not least, Weyl non-regular quantization is briefly discussed from the perspective of the so-called polymer representations proposed for Loop Quantum Gravity in connection with diffeomorphism invariant vacuum states.
Gauge Theories Of Strong, Weak, And Electromagnetic Interactions: Second Edition
by Chris QuiggThis monograph presents a coherent and elementary introduction to Gauge theories of the fundamental interactions and their applications to high-energy physics. It deals with the logic and structure of local Gauge symmetries and Gauge theories, from quantum electrodynamics through unified theories of the interactions among leptons and quarks. Many explicit calculations provide the reader with practice in computing the consequences of these theories and offer a perspective on key experimental investigations. First published in 1983, this text is ideal for a one-semester course on Gauge theories and particle physics. Specialists in particle physics and others who wish to understand the basic ideas of Gauge theories will find it useful as a reference and for self-study.
Gauge Theories in Particle Physics, 40th Anniversary Edition: From Relativistic Quantum Mechanics to QED, Fifth Edition
by Anthony J.G. Hey Ian J AitchisonThe fifth edition of this well-established, highly regarded two-volume set continues to provide a fundamental introduction to advanced particle physics while incorporating substantial new experimental results, especially in the areas of Higgs and top sector physics, as well as CP violation and neutrino oscillations. It offers an accessible and practical introduction to the three gauge theories comprising the Standard Model of particle physics: quantum electrodynamics (QED), quantum chromodynamics (QCD), and the Glashow-Salam-Weinberg (GSW) electroweak theory.Volume 1 of this updated edition provides a broad introduction to the first of these theories, QED. The book begins with self-contained presentations of relativistic quantum mechanics and electromagnetism as a gauge theory. Lorentz transformations, discrete symmetries, and Majorana fermions are covered. A unique feature is the elementary introduction to quantum field theory, leading in easy stages to covariant perturbation theory and Feynman graphs, thereby establishing a firm foundation for the formal and conceptual framework upon which the subsequent development of the three quantum gauge field theories of the Standard Model is based. Detailed tree-level calculations of physical processes in QED are presented, followed by an elementary treatment of one-loop renormalization of a model scalar field theory, and then by the realistic case of QED. The text includes updates on nucleon structure functions and the status of QED, in particular the precision tests provided by the anomalous magnetic moments of the electron and muon.The authors discuss the main conceptual points of the theory, detail many practical calculations of physical quantities from first principles, and compare these quantitative predictions with experimental results, helping readers improve both their calculation skills and physical insight.Each volume should serve as a valuable handbook for students and researchers in advanced particle physics looking for an introduction to the Standard Model of particle physics.
Gauge Theories in Particle Physics, 40th Anniversary Edition: Non-Abelian Gauge Theories: QCD and The Electroweak Theory, Fifth Edition
by Anthony J.G. Hey Ian J AitchisonThe fifth edition of this well-established, highly regarded two-volume set continues to provide a fundamental introduction to advanced particle physics while incorporating substantial new experimental results, especially in the areas of Higgs and top sector physics, as well as CP violation and neutrino oscillations. It offers an accessible and practical introduction to the three gauge theories comprising the Standard Model of particle physics: quantum electrodynamics (QED), quantum chromodynamics (QCD), and the Glashow-Salam-Weinberg (GSW) electroweak theory.Volume 2 of this updated edition covers the two non-Abelian gauge theories of QCD and the GSW theory. A distinctive feature is the extended treatment of two crucial theoretical tools: spontaneous symmetry breaking and the renormalization group. The underlying physics of these is elucidated by parallel discussions of examples from condensed matter systems: superfluidity and superconductivity, and critical phenomena. This new edition includes updates to jet algorithms, lattice field theory, CP violation and the CKM matrix, and neutrino physics.New to the fifth edition: Tests of the Standard Model in the Higgs and top quark sectors The naturalness problem and responses to it going beyond the Standard Model The Standard Model as an effective field theory Each volume should serve as a valuable handbook for students and researchers in advanced particle physics looking for an accessible introduction to the Standard Model of particle physics.
Gauge Theories of Weak Decays
by Andrzej BurasThis is the first advanced, systematic and comprehensive look at weak decays in the framework of gauge theories. Included is a large spectrum of topics, both theoretical and experimental. In addition to explicit advanced calculations of Feynman diagrams and the study of renormalization group strong interaction effects in weak decays, the book is devoted to the Standard Model Effective Theory, dominating present phenomenology in this field, and to new physics models with the goal of searching for new particles and interactions through quantum fluctuations. This book will benefit theorists, experimental researchers, and Ph.D. students working on flavour physics and weak decays as well as physicists interested in physics beyond the Standard Model. In its concern for the search for new phenomena at short distance scales through the interplay between theory and experiment, this book constitutes a travel guide to physics far beyond the scales explored by the Large Hadron Collider at CERN.

Gauge/Gravity Duality: Foundations and Applications
by Martin Ammon Johanna ErdmengerGauge/gravity duality creates new links between quantum theory and gravity. It has led to new concepts in mathematics and physics, and provides new tools to solve problems in many areas of theoretical physics. This book is the first textbook on this important topic, enabling graduate students and researchers in string theory and particle, nuclear and condensed matter physics to get acquainted with the subject. Focusing on the fundamental aspects as well as on the applications, this textbook guides readers through a thorough explanation of the central concepts of gauge/gravity duality. For the AdS/CFT correspondence, it explains in detail how string theory provides the conjectured map. Generalisations to less symmetric cases of gauge/gravity duality and their applications are then presented, in particular to finite temperature and density, hydrodynamics, QCD-like theories, the quark-gluon plasma and condensed matter systems. The textbook features a large number of exercises, with solutions available online at www. cambridge. org/9781107010345.
Gauge/String Duality, Hot QCD and Heavy Ion Collisions
by Hong Liu Jorge Casalderrey-Solana David Mateos Krishna Rajagopal Urs Achim WiedemannHeavy ion collision experiments recreating the quark-gluon plasma that filled the microseconds-old universe have established that it is a nearly perfect liquid that flows with such minimal dissipation that it cannot be seen as made of particles. String theory provides a powerful toolbox for studying matter with such properties. This book provides a comprehensive introduction to gauge/string duality and its applications to the study of the thermal and transport properties of quark-gluon plasma, the dynamics of how it forms, the hydrodynamics of how it flows, and its response to probes including jets and quarkonium mesons. Calculations are discussed in the context of data from RHIC and LHC and results from finite temperature lattice QCD. The book is an ideal reference for students and researchers in string theory, quantum field theory, quantum many-body physics, heavy ion physics and lattice QCD.
Gay Shame
by David M. Halperin Valerie TraubEver since the 1969 Stonewall Riots, "gay pride" has been the rallying cry of the gay rights movement and the political force behind the emergence of the field of lesbian and gay studies. But has something been lost, forgotten, or buried beneath the drive to transform homosexuality from a perversion to a proud social identity? Have the political requirements of gay pride repressed discussion of the more uncomfortable or undignified aspects of homosexuality? Gay Shame seeks to lift this unofficial ban on the investigation of homosexuality and shame by presenting critical work from the most vibrant frontier in contemporary queer studies. An esteemed list of contributors tackles a range of issues--questions of emotion, disreputable sexual histories, dissident gender identities, and embarrassing figures and moments in gay history--as they explore the possibility of reclaiming shame as a new, even productive, way to examine lesbian and gay culture. Gay Shame constitutes nothing less than a major redefinition and revitalization of the field.
Gay Voluntary Associations in New York: Public Sharing and Private Lives
by Moshe ShokeidGay Voluntary Associations in New York is a sensitive and insightful ethnography of social groups that have gathered around common interests in an urban LGBT population from the time of the AIDS crisis to the present. Anthropologist Moshe Shokeid examines the social discourse of sex, love, friendship, and spiritual life in which these communities are passionately engaged.<P> Drawn from long-term anthropological research in New York City, Gay Voluntary Associations in New York uses participant observation to explore such diverse social associations and religious organizations as seniors groups, interracials, bisexuals, sexual compulsives, gay bears, and Catholic, Protestant, and Jewish gay congregations. As an outside observer--neither gay nor American-born--Shokeid examines the social discourse within these voluntary associations from a critical vantage point. In addition to the personal information and intimate expressions of empathy freely shared in the company of strangers at social gatherings, individual stories and experiences are woven into the narrative to illustrate the existential conditions and emotional template of gay life in the city. Shokeid's nuanced portrait of the affective relationships within these groups offers deeper comprehension of the social dynamics and emotional realities of gay urban communities in the United States.
Gay, Straight, And The Reason Why: The Science Of Sexual Orientation
by Simon LeVayWhat causes a child to grow up gay or straight? Neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay takes the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. In this second edition, LeVay adds a chapter on bisexuality, reviews some uncommon forms of sexuality, and considers whether there could be a biological basis for subtypes of gay people such as "butch" and "femme" lesbians.
