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.

Gear Accuracy: A Treatise on Gear Noise Excitation, Vibration Generation, and Dynamics of Operation (Mechanical Engineering Series)
by Stephen P. RadzevichThis book provides a comprehensive profile the range of developments in gear science and gear engineering mainly those related to noise emission and vibration generation. The problem of noise emission and vibration generation is a challenging one. This scientific and engineering problem requires efforts of gear experts of different areas, and it got no satisfactory solution yet. Gear experts of different countries (USA, Israel, Poland, and Ukraine) have contributed to this volume. The latest accomplishments in scientific theory of gearing, gear design, production, inspection, and application are covered by this volume. The readers’ attention is focused mainly on the achievements in the field that lead to a significant reduction of gear noise excitation and vibration generation in gearing of all designs, namely, in parallel-axes gearing, in intersected-axes gearing, and in crossed-axes gearing. The concept of geometrically-accurate gearing (parallel-axes gearing, intersected-axes gearing, and crossed-axes gearing) is lays in the foundation of the undertaken research on gear noise emission and vibration generation. To the best possible extent, the kinematical and geometrical components of the problem under consideration are outlined at the beginning of this volume of the book when the accuracy of gears are discussed. The illustration of the various aspects of the problem is provided in the rest sections of the book volume. In particular, the readers’ attention is focused here also on the key problems, the poor knowledge of the scientific theory of gearing may lead to. This latter issue arouses even in leading gear manufacturing companies. The bottom line is as follows: In order to succeed in solving the noise excitation, and the vibration generation problem in gearing, high level of proficiency in the scientific theory of gearing is a must, as this theory provides the user with an in-depth understanding of meshing of the gear teeth, as well as with powerful tools to solve gear problems of this sort in cases when something goes wrong.

Gears: Volume 1: Geometric and Kinematic Design (Springer Series in Solid and Structural Mechanics #10)
by Vincenzo VulloThe book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

Geeks, Genes, and the Evolution of Asperger Syndrome
by Dean Falk Eve Penelope SchofieldIn this unusual book an evolutionary anthropologist and her coauthor/granddaughter, who has Asperger syndrome, examine the emergence and spread of Asperger syndrome and other forms of high-functioning autism. The authors speak to readers with autism, parents, teachers, clinicians, psychologists, psychiatrists, other health-care providers, autism researchers, evolutionary biologists, geneticists, paleoanthropologists, and people who simply enjoy reading about science.Using the latest findings regarding brain evolution and the neurological, genetic, and cognitive underpinnings of autistic individuals at the high end of the spectrum, Falk theorizes that many characteristics associated with Asperger syndrome are by-products of the evolution of advanced mental processing. She explores the origins of autism, whether it is currently evolving, how it differs in males and females, and whether it is a global phenomenon. Additionally, Eve Schofield, who was diagnosed with Asperger syndrome as a child, provides firsthand accounts of what it is like to grow up as an &“Aspie.&”
