A classroom-tested book addressing key issues of electrical noiseThis book examines noise phenomena in linear and nonlinear high-frequency circuits from both qualitative and quantitative perspectives. The authors explore important noise mechanisms using equivalent sources and analytical and numerical methods. Readers learn how to manage electrical noise to improve the sensitivity and resolution of communication, navigation, measurement, and other electronic systems.Noise in High-Frequency Circuits and Oscillators has its origins in a university course taught by the authors. As a result, it is thoroughly classroom-tested and carefully structured to facilitate learning. Readers are given a solid foundation in the basics that allows them to proceed to more advanced and sophisticated themes such as computer-aided noise simulation of high-frequency circuits.Following a discussion of mathematical and system-oriented fundamentals, the book covers:* Noise of linear one- and two-ports* Measurement of noise parameters* Noise of diodes and transistors* Parametric circuits* Noise in nonlinear circuits* Noise in oscillators* Quantization noiseEach chapter contains a set of numerical and analytical problems that enable readers to apply their newfound knowledge to real-world problems. Solutions are provided in the appendices.With their many years of classroom experience, the authors have designed a book that is ideal for graduate students in engineering and physics.

Inventor and futurist Ray Kurzweil examines the next step in the evolutionary process of the union of human and machine. He foresees the dawning of a new civilization where we will be able to transcend our biological skills with the vastly greater capacity, speed and knowledge-sharing abilities of our creations. In practical terms, human aging and illness will be reversed; pollution will be stopped and world hunger and poverty will be solved. There will be no clear distinction between human and machine, real reality and virtual reality. The Singularity is Near offers a view of the coming age that is both a dramatic culmination of centuries of technological ingenuity and a genuinely inspiring vision of our ultimate destiny.

High Price by Carl Hart is a groundbreaking work on neuroscience and addiction
As a youth, Carl Hart didn't see the value of school, studying just enough to keep him on the basketball team. At the same time, he was immersed in street life, dealing drugs and committing petty larceny. Today, he is a cutting-edge neuroscientist whose landmark, controversial research is redefining our understanding of addiction.
In this provocative and eye-opening memoir, he recalls his journey of self-discovery, how he escaped a life of crime and drugs and avoided becoming one of the crack addicts he now studies. Interweaving past and present, Hart goes beyond the hype as he examines the relationship between drugs and pleasure, choice, and motivation, both in the brain and in society. His findings shed new light on common ideas about race, poverty, and drugs and explain why current policies are failing. But while Hart escaped the ghetto, he has not turned his back on it. Determined to make a difference, he tirelessly applies his science to help save real lives. But balancing his former street life with his achievements today has not been easy-a struggle he reflects on publicly for the first time.
Homocide (the inspiration for The Wire) meets Oliver Sacks' The Man Who Mistook His Wife for A Hat, this book applies neuroscience to crime, addiction and the most urgent and destructive issues of our times.
Carl Hart is an Associate Professor in the Departments of Psychology and Psychiatry at Columbia University. He is also a Research Scientist in the Division of Substance Abuse at the New York State Psychiatric Institute. He and his work are featured in Eugene Jarecki's acclaimed documentary The House I Live In. The film examines the war on drugs and highlights some of the research that Hart includes in High Price. He lives in New York City.

From a brilliant new literary voice comes a groundbreaking exploration of how trails help us understand the world--from tiny ant trails to hiking paths that span continents, from interstate highways to the Internet.In 2009, while thru-hiking the Appalachian Trail, Robert Moor began to wonder about the paths that lie beneath our feet: How do they form? Why do some improve over time while others devolve? What makes us follow or strike off on our own? Over the course of the next seven years, Moor traveled the globe, exploring trails of all kinds, from the miniscule to the massive. He learned the tricks of master trail-builders, hunted down long-lost Cherokee trails, and traced the origins of our road networks and the Internet. In each chapter, Moor interweaves his adventures with findings from science, history, philosophy, and nature writing--combining the nomadic joys of Peter Matthiessen with the eclectic wisdom of Lewis Hyde's The Gift. Throughout, Moor reveals how this single topic--the oft-overlooked trail--sheds new light on a wealth of age-old questions: How does order emerge out of chaos? How did animals first crawl forth from the seas and spread across continents? How has humanity's relationship with nature and technology shaped world around us? And, ultimately, how does each of us pick a path through life? Moor has the essayist's gift for making new connections, the adventurer's love for paths untaken, and the philosopher's knack for asking big questions. With a breathtaking arc that spans from the dawn of animal life to the digital era, On Trails is a book that makes us see our world, our history, our species, and our ways of life anew.
Abstract The habitat of the four extant hyena species covers all of Africa and large parts of Asia. Hyenas living in this enormous area have been described by local and western observers for more than 2000 years. Many names have been given to the hyenas in the wide range of languages in which they have been described and several legends and wrong ideas about hyenas have also been spread. In the present study we want to retrace how the wrong perceptions about the hyena, the 'histoires absurdes' as Comte de Buffon has called them, developed and how they were overcome by several scholars in a protracted process. Due to their research work we know today that the mysterious animal 'hyaena' comprises four species which together build up the Hyaenidae family. We will start by introducing these species shortly (chap. 2). Thereafter we return to the beginning of the hyena history and outline the classical Greco-Roman reports on the hyena and how until the Renaissance and beyond these modelled the occidental perceptions of this animal (chap. 3). Then we examine how the single members of the Hyaenidae family were discovered, described and named by later naturalists and zoologists. In chronological order these were the striped hyena (Hyaena hyaena), the spotted hyena (Crocuta crocuta), the brown hyena (Parahyaena brunnea) and finally the aardwolf (Proteles cristatus) (chap. 4 and 5). Special attention is paid to the first zoological description of the striped hyena by the traveller and naturalist Engelbert Kaempfer from the end of the 17th century. The value of this widely unknown report lies in the fact that it actually made the breakthrough to overcome the confused and puzzling ideas about the hyena which had prevailed up to that time (chap. 4). We conclude our survey with a chapter on 'imaginary' hyenas in which we deal with animals that have been mistaken for real hyenas. In one of these cases the imagined hyena was apparently nothing but a fantasy creature, comprising nevertheless characteristic traits of two real hyena species (chap. 6). The descriptions of the discovery, naming and localisation of the hyena species are followed by two appendices which contain extensive original source texts (some of which are available in translation for the first time) and pictorial material....
