Yang–Baxter Deformation of 2D Non-Linear Sigma Models: Towards Applications to AdS/CFT (SpringerBriefs in Mathematical Physics #40)
by Kentaroh YoshidaIn mathematical physics, one of the fascinating issues is the study of integrable systems. In particular, non-perturbative techniques that have been developed have triggered significant insight for real physics. There are basically two notions of integrability: classical integrability and quantum integrability. In this book, the focus is on the former, classical integrability. When the system has a finite number of degrees of freedom, it has been well captured by the Arnold–Liouville theorem. However, when the number of degrees of freedom is infinite, as in classical field theories, the integrable structure is enriched profoundly. In fact, the study of classically integrable field theories has a long history and various kinds of techniques, including the classical inverse scattering method, which have been developed so far. In previously published books, these techniques have been collected and well described and are easy to find in traditional, standard textbooks. One of the intriguing subjects in classically integrable systems is the investigation of deformations preserving integrability. Usually, it is not considered systematic to perform such a deformation, and one must study systems case by case and show the integrability of the deformed systems by constructing the associated Lax pair or action-angle variables. Recently, a new, systematic method to perform integrable deformations of 2D non-linear sigma models was developed. It was invented by C. Klimcik in 2002, and the integrability of the deformed sigma models was shown in 2008. The original work was done for 2D principal chiral models, but it has been generalized in various directions nowadays. In this book, the recent progress on this Yang–Baxter deformation is described in a pedagogical manner, including some simple examples. Applications of Yang–Baxter deformation to string theory are also described briefly.
Yanzhuang Meteorite: Mineralogy and Shock Metamorphism
by Xiande Xie Ming ChenThis book investigates the mineralogy and shock effects of Yanzhuang chondrite, using modern micro-mineralogical experimental techniques, including SEM, TEM, EPMA, Raman microprobe spectroscopy, instrumental neutron activation analysis, X-ray micro-diffraction analysis, micro-PIXE analysis and laser ablation ICP-MS. The micro-structural and micro-morphological characteristics as well as chemical composition of minerals were studied in details. Based on the studies in the shock effects of rocks and minerals, and the detailed study in the shock-produced melt, the book concludes that Yanzhuang chondrite is the most heavily shocked ordinary H group chondrite ever found and that it contains the most abundant shock induced melt among all known shock-melt-bearing chondritic meteorites.

A Year of Living Simply: The joys of a life less complicated (Kate Humble)
by Kate Humble'Simply wonderful.' - BEN FOGLE'Kate's book has the warmth and calming effect of a log fire and a glass of wine. Unknit your brow and let go. It's a treat.' - GARETH MALONE'Kate Humble pours her enviable knowledge into attainable goals. It's a winning combination and the prize - a life in balance with nature - is definitely worth claiming.' - LUCY SIEGLE'As ever, where Kate leads, I follow. She has made me reassess and reset.' - DAN SNOW'Kate Humble's new book is a lesson in moving on from a tragedy and finding our place in the world' - WOMAN & HOME'A Year of Living Simply is timely, given that the pandemic has forced most of us, in some way to simplify our lives, whether we planned to or not. Kate wrote it before any of us were aware of the upcoming crisis, but it captures the current moment perfectly... It's not necessarily a "how to" book, more of a "why not try?" approach.' - FRANCESCA BABB, MAIL ON SUNDAY YOU'What I particularly love is her philosophy for happiness, which is the subject of her new book, A Year of Living Simply. The clue is in the title. Remember the basics. Instead of barging through the day on autopilot, really stop to think about the tiniest little things that added a moment of joy. No, of course stopping and smelling the flowers won't cure all our ills and woes. But taking the time to savour the things that bring pleasure, really being in that moment and appreciating it, can remind you that most days have moments that buoy your mood.' - JO ELVIN, MAIL ON SUNDAY YOUIf there is one thing that most of us aspire to, it is, simply, to be happy. And yet attaining happiness has become, it appears, anything but simple. Having stuff - The Latest, The Newest, The Best Yet - is all too often peddled as the sure fire route to happiness. So why then, in our consumer-driven society, is depression, stress and anxiety ever more common, affecting every strata of society and every age, even, worryingly, the very young? Why is it, when we have so much, that many of us still feel we are missing something and the rush of pleasure when we buy something new turns so quickly into a feeling of emptiness, or purposelessness, or guilt?So what is the route to real, deep, long lasting happiness? Could it be that our lives have just become overly crowded, that we've lost sight of the things - the simple things - that give a sense of achievement, a feeling of joy or excitement? That make us happy. Do we need to take a step back, reprioritise? Do we need to make our lives more simple? Kate Humble's fresh and frank exploration of a stripped-back approach to life is uplifting, engaging and inspiring - and will help us all find balance and happiness every day.

Yellow Tourism: Crime and Corruption in the Holiday Sector (Tourism, Hospitality & Event Management)
by Alexis Papathanassis Stavros Katsios Nicoleta Ramona DinuThis book presents the latest research and novel case studies on crime and corruption in the tourism and hospitality industry. It approaches tourism as both a globalised business impacting the livelihood of millions of people, and a highly challenging field of action for national legislators and law enforcement agencies. The global nature and ubiquity of tourism, as well as the core elements of the holiday experience - such as interactions with unknown environments and places, a care-free mind-set, novelty-seeking behaviour and anonymity - render it highly susceptible to victimisation, crime and corruption. Accordingly, the book addresses a comprehensive set of emerging issues, including: conflict and fraud during holidays; criminal and negligence offences at tourists’ expense; exploitation and mistreatment of service workers; deterioration of heritage, cultural and natural resources; and securitisation of tourism.
Yellowstone Cougars: Ecology before and during Wolf Restoration
by Toni K. Ruth Polly C. Buotte Maurice G. HornockerYellowstone Cougars examines the effect of wolf restoration on the cougar population in Yellowstone National Park—one of the largest national parks in the American West. No other study has ever specifically addressed the theoretical and practical aspects of competition between large carnivores in North America. The authors provide a thorough analysis of cougar ecology, how they interact with and are influenced by wolves—their main competitor—and how this knowledge informs management and conservation of both species across the West. Of practical importance, Yellowstone Cougars addresses the management and conservation of multiple carnivores in increasingly human-dominated landscapes. The authors move beyond a single-species approach to cougar management and conservation to one that considers multiple species, which was impossible to untangle before wolf reestablishment in the Yellowstone area provided biologists with this research opportunity. Yellowstone Cougars provides objective scientific data at the forefront of understanding cougars and large carnivore community structure and management issues in the Greater Yellowstone Ecosystem, as well as in other areas where wolves and cougars are reestablishing. Intended for an audience of scientists, wildlife managers, conservationists, and academics, the book also sets a theoretical precedent for writing about competition between carnivorous mammals.

Yellowstone's Destabilized Ecosystem: Elk Effects, Science, and Policy Conflict
by Frederic H. WagnerWagner, one of our most distinguished wildlife biologists, is a strong critic of ecological practices in the national parks. This book provides an assessment of the ecological history of Yellowstone's northern range, since before the park existed, showing the impact of US Park Service policies on the health of the areas they oversee. He demonstrates that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area. This is a major contribution to reconstructing the ecology of this region over the course of the past 500 years. It is also a critique of US Park Service management policies and their stewardship of the nation's most cherished natural areas. Wagner's book will generate substantial attention and debate both in the scientific and policy/management communities.

The Yosemite: Illustrated Edition (Mobi Classics Series)
by John MuirAn essential companion for visitors, this book by the famed conservationist offers informed appraisals of Yosemite's plant and animal life and exudes an almost mystical love for its natural beauty.
The Yosemite: John Muir's quest to preserve the wilderness (John Muir: The Eight Wilderness-Discovery Books #3)
by John Muir‘All these colours, from the blue sky to the yellow valley smoothly blending as they do in a rainbow, making a wall of light ineffably fine.’Having spent significant time obsessively exploring and learning about the Sierra, John Muir’s passion for and belief in preserving the wilderness steadily grew. He believed that excessive grazing and logging would result in its eventual destruction, and so campaigned to designate the area as a protected national park.In 1890, the US Congress passed the National Park Bill, and the Yosemite and Sequoia national parks were established. At the time of writing, Muir’s views on conservation of the wilderness were totally radical; today, environmental activists are too often brushed aside in favour of something faster, easier, and cheaper.Muir not only educates us in the particulars of the botanicals of this spectacular landscape, but also inadvertently traps us in his web of enthusiasm for the beauty and significance of Mother Nature. The Yosemite gives us the tools to construct a detailed mental map of the Sierra, and leaves us with the resolution to be more compassionate and environmentally mindful.First published in 1912, and with a new introduction from Muir authority Terry Gifford, the message in The Yosemite is perhaps more pertinent now than it ever was. There is a lot to thank Muir for, not least opening our eyes to the earth beneath our feet.

You Are Here: A Brief Guide to the World
by Nicholas CraneOne word binds us all: geography. We are all geographers, human beings who care about the places we think of as 'home' - our habitat. And yet we have lost touch with the connection between our actions and the state of the planet that we all share. We need a new narrative that restores the connections between humanity and the Earth.We are being confronted by a daily barrage of geographical stories on climate change, geopolitics, population growth, migration, dwindling resources, polluted oceans and natural hazards. These are planetary concerns affecting all people and all places. They are challenges which can be addressed through geography.In this distillation of a lifetime's work, Nicholas Crane makes the compelling case that never has geography been so important. On this finite orb, with its battered habitat, sustained in dark space by a thin, life-giving atmosphere, we have reached a point in our collective geographical journey where knowledge is the best guarantor of the future.
You Are Here: Around the World in 92 Minutes
by Chris HadfieldIn You Are Here, celebrated astronaut Chris Hadfield gives us the really big picture: this is our home, as seen from space. The millions of us who followed Hadfield's news-making Twitter feed from the International Space Station thought we knew what we were looking at when we first saw his photos. But we may have caught the beauty and missed the full meaning. Now, through photographs – many of which have never been shared – Hadfield unveils a fresh and insightful look at our planet. He sees astonishing detail and importance in these images, not just because he's spent months in space but because his in-depth knowledge of geology, geography and meteorology allows him to reveal the photos' mysteries.Featuring Hadfield's favourite images, You Are Here is divided by continent and represents one (idealized) orbit of the ISS. Surprising, thought-provoking and visually delightful, it opens a singular window on our planet, using remarkable photographs to illuminate the history and consequences of human settlement, the magnificence of never-before-noticed landscapes, and the power of the natural forces shaping our world and the future of our species.
