Gasotransmitters: Physiology and Pathophysiology
by Guzel F. Sitdikova Thomas M. Weiger Anton HermannSince the epochal discovery of the radical and highly toxic gas nitric oxide (NO) as a signaling molecule, two other no less toxic gases - carbon monoxide (CO) and hydrogen sulfide (H2S) - have been found to also be involved in a plethora of physiological and pathophysiological functions. The gases termed gasotransmitters play an increasingly important role in understanding how signalling into and between cells is modulated and fine-tuned. The advent of gasotransmitters has profoundly changed our way of thinking about biosynthesis, liberation, storage and action mechanisms in cellular signaling. In recent years an impressive amount of new data, distributed throughout the existing literature, has been generated. For this book the editors have recruited distinguished colleagues in the field to summarize and review important biological, pharmacological and medical functions and their implications, as well as methods for the detection of gasotransmitters.
Gaston Bachelard: Critic of Science and the Imagination (Routledge Studies in Twentieth-Century Philosophy #Vol. 9)
by Cristina ChimissoIn this new study, Cristina Chimisso explores the work of the French Philosopher of Science, Gaston Bachelard (1884-1962) by situating it within French cultural life of the first half of the century. The book is introduced by a study - based on an analysis of portraits and literary representations - of how Bachelard's admirers transformed him into the mythical image of the Philosopher, the Patriarch and the 'Teacher of Happiness'. Such a projected image is contrasted with Bachelard's own conception of philosophy and his personal pedagogical and moral ideas.This pedagogical orientation is a major feature of Bachelard's texts, and one which deepens our understanding of the main philosophical arguments. The primary thesis of the book is based on the examination of the French educational system of the time and of French philosophy taught in schools and conceived by contemporary philosophers. This approach also helps to explain Bachelard's reception of psychoanalysis and his mastery of modern literature. Gaston Bachelard: Critic of Science and the Imagination thus allows for a new reading of Bachelard's body of work, whilst at the same time providing an insight into twentieth century French culture.

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.

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.
