Ultra

A young ultra-marathon runner is pushed to the breaking point and beyond in this gripping tale of physical endurance and emotional healing. Quinn has been called a superhero and a freak of nature. At age 13, he's an amazing distance runner. He takes on the second-hardest challenge of his life when he enters his first ultramarathon: a grueling 100-mile, 24-hour-long race that will push him to the very limit of his endurance. While Quinn struggles to go on -- up a mountain and through the night, as his muscles break down and he begins to hallucinate -- we learn why the ultra-marathon is only the second hardest thing he has endured in his young life. And maybe this devastating event from his past is exactly what Quinn has been running from . . . Framed as an interview with a media commentator after Quinn's newsmaking finish, this remarkable debut novel from ultra-marathon runner David Carroll reminds us that when we dare to challenge what is possible, the word impossible loses its meaning.

"Finding Ultra" recounts Roll's remarkable journey from an overweight 40-year-old to the starting line of the elite 320-mile Ultraman competition in a beautifully written portrait of what willpower can accomplish.

ULTRA WIDEBAND WIRELESS COMMUNICATION AN INTERNATIONAL PANEL OF EXPERTS PROVIDE MAJOR RESEARCH ISSUES AND A SELF-CONTAINED, RAPID INTRODUCTION TO THE THEORY AND APPLICATION OF UWB This book delivers end-to-end coverage of recent advances in both the theory and practical design of ultra wideband (UWB) communication networks. Contributions offer a worldwide perspective on new and emerging applications, including WPAN, sensor and ad hoc networks, wireless telemetry, and telemedicine. The book explores issues related to the physical layer, medium access layer, and networking layer. Following an introductory chapter, the book explores three core areas: Analysis of physical layer and technology issues System design elements, including channel modeling, coexistence, and interference mitigation and control Review of MAC and network layer issues, up to the application Case studies present examples such as network and transceiver design, assisting the reader in understanding the application of theory to real-world tasks. Ultra Wideband Wireless Communication enables technical professionals, graduate students, engineers, scientists, and academic and professional researchers in mobile and wireless communications to become conversant with the latest theory and applications by offering a survey of all important topics in the field. It also serves as an advanced mathematical treatise; however, the book is organized to allow non-technical readers to bypass the mathematical treatments and still gain an excellent understanding of both theory and practice.

THE #1 INTERNATIONAL BESTSELLER • LONGLISTED FOR THE BAILLIE GIFFORD PRIZE FOR NONFICTION • The bestselling and eye-opening investigation into the science, economics, history and impact of ultra-processed food. Named a Best Book of the Year by NPR • The Economist • The Times • The New Yorker • Smithsonian • Daily Mail • The Guardian • Financial Times • and more! It's not you, it's the food. How much of our daily caloric intake comes from ingesting substances that, technically speaking, do not meet traditional definitions of “food”? Chances are, if you’re eating something that came wrapped in plastic and contains a funky ingredient you don’t have in your kitchen, it's most likely—almost definitely—ultra-processed food, or UPF. More than the principal obstacle to “eating right,” UPF has been linked to metabolic disease, depression, inflammation, anxiety, and cancer, while the production, distribution, and disposal of UPF and related products globally is known to cause devastating environmental damage. At the same time, UPF represents the dominant, nigh-unavoidable food culture for millions upon millions of eaters. Medical doctor and broadcaster Chris van Tulleken has spent his career trying to reframe the conversation around eating right, balancing the hard (and sometimes shocking) facts about what we're putting into our bodies with empathy for the natural desire to keep eating what we like, have time for, and can afford. As he argues in this book, we are all participants in an experiment we didn't consent to, one to determine how to get us to buy as much ultra-processed food as possible. It’s not as simple as stumbling across the right diet trend, finding time to meal plan, or avoiding over-indulging in sugar, fat, or carbs or any other culprit. Nor is it a matter of individual will. It’s about learning to live in “the third age of eating”—defined by the overwhelming abundance of ultra-processed eating options—and arming yourself with the simple and not-so-simple facts that will help you make the choices that are right for you.

A comprehensive summary of the state of the art in Ultra Wideband system engineering, from components to system engineering aspects.

Ultra-wideband Radio Frequency Identification Systems describes the essentials of radio frequency identification (RFID)systems as well as their target markets. The book covers a study of commercially available RFID systems and characterizes their performance in terms of read range and reliability in the presence of conductive and dielectric materials. The capabilities and limitations of commercial RFID systems are reported followed by comprehensive discussions of the advantages and challenges of using ultra-wideband (UWB) technology for tag/reader communications. The book presents practical aspects of RFID system such as: EPC global and ISO standards, implementation, and target markets in a simple and easy to understand language.
