Odyssey of Light in Nonlinear Optical Fibers: Theory and Applications
by Kuppuswamy Porsezian Ramanathan GanapathyOdyssey of Light in Nonlinear Optical Fibers: Theory and Applications presents a collection of breakthrough research portraying the odyssey of light from optical solitons to optical rogue waves in nonlinear optical fibers. The book provides a simple yet holistic view on the theoretical and application-oriented aspects of light, with a special focus on the underlying nonlinear phenomena. <P><P>Exploring the very frontiers of light-wave technology, the text covers the basics of nonlinear fiberoptics and the dynamics of electromagnetic pulse propagation in nonlinear waveguides. It also highlights some of the latest advances in nonlinear optical fiber technology, discussing hidden symmetry reductions and Ablowitz–Kaup–Newell–Segur (AKNS) hierarchies for nonautonomous solitons, state-of-the-art Brillouin scattering applications, backpropagation, and the concept of eigenvalue communication—a powerful nonlinear digital signal processing technique that paves the way to overcome the current limitations of traditional communications methods in nonlinear fiber channels. <P><P>Key chapters study the feasibility of the eigenvalue demodulation scheme based on digital coherent technology by throwing light on the experimental study of the noise tolerance of the demodulated eigenvalues, investigate matter wave solitons and other localized excitations pertaining to Bose–Einstein condensates in atom optics, and examine quantum field theory analogue effects occurring in binary waveguide arrays, plasmonic arrays, etc., as well as their ensuing nonlinear wave propagation. Featuring a foreword by Dr. Akira Hasegawa, the father of soliton communication systems, Odyssey of Light in Nonlinear Optical Fibers: Theory and Applications serves as a curtain raiser to usher in the photonics era. The technological innovations at the core of the book form the basis for the next generation of ultra-high speed computers and telecommunication devices.
Oedipus Rex in the Genomic Era: Human Behaviour, Law and Society
by Yulia Kovas Fatos SelitaThis book explores the answers to fundamental questions about the human mind and human behaviour with the help of two ancient texts. The first is Oedipus Rex (Oedipus Tyrannus) by Sophocles, written in the 5th century BCE. The second is human DNA, with its origins around 4 billion years ago, and continuously revised by chance and evolution. With Sophocles as a guide, the authors take a journey into the Genomic era, an age marked by ever-expanding insights into the human genome. Over the course of this journey, the book explores themes of free will, fate, and chance; prediction, misinterpretation, and the burden that comes with knowledge of the future; self-fulfilling and self-defeating prophecies; the forces that contribute to similarities and differences among people; roots and lineage; and the judgement of oneself and others.Using Oedipus Rex as its lens, this novel work provides an engaging overview of behavioural genetics that demonstrates its relevance across the humanities and the social and life sciences. It will appeal in particular to students and scholars of genetics, education, psychology, sociology, and law.
The Oestrid Flies: Biology, Host-parasite Relationships, Impact and Management
by D. D. Colwell P. J. Scholl M. J. R. HallThis book provides an in-depth review and analysis of the biology of adults and larvae of the Family Oestridae (commonly known as botflies, or warble flies). Oestrid flies cause myiasis (invasion of living tissue by the larvae), and are a major pest of both domestic and wild animals worldwide. The book presents a comparative investigation of the life histories and adaptation to parasitism exhibited by this unique family of flies. It also gives a detailed survey of each genus and provides a synopsis of the taxonomy of the family. It contains chapters on morphology, life history, host-parasite relationships, taxonomy and behavior.
Of a Feather: A Brief History of American Birding
by Scott WeidensaulEuropeans were awestruck by a continent awash with birds. Today tens of millions of Americans birders have made a once eccentric hobby into something so mainstream its (almost) cool. Scott Weidensaul traces the colorful evolution of American birding.
Of a Fire on the Moon
by Norman MailerFor many, the moon landing was the defining event of the twentieth century. So it seems only fitting that Norman Mailer--the literary provocateur who altered the landscape of American nonfiction--wrote the most wide-ranging, far-seeing chronicle of the Apollo 11 mission. A classic chronicle of America's reach for greatness in the midst of the Cold War, Of a Fire on the Moon compiles the reportage Mailer published between 1969 and 1970 in Life magazine: gripping firsthand dispatches from inside NASA's clandestine operations in Houston and Cape Kennedy; technical insights into the magnitude of their awe-inspiring feat; and prescient meditations that place the event in human context as only Mailer could.
Of Apes and Ancestors
by Ian HeskethTell me, sir, is it on your grandmother's or your grandfather's side that you are descended from an ape?In June of 1860, some of Britain's most influential scientific and religious authorities gathered in Oxford to hear a heated debate on the merits of Charles Darwin's recently published Origin of Species. The Bishop of Oxford, "Soapy" Samuel Wilberforce, clashed swords with Darwin's most outspoken supporter, Thomas Henry Huxley. The latter's triumph, amid quips about apes and ancestry, has become a mythologized event, symbolizing the supposed war between science and Christianity. But did the debate really happen in this way? Of Apes and Ancestors argues that this one-dimensional interpretation was constructed and disseminated by Darwin's supporters, becoming an imagined victory in the struggle to overcome Anglican dogmatism. By reconstructing the Oxford debate and carefully considering the individual perspectives of the main participants, Ian Hesketh argues that personal jealousies and professional agendas played a formative role in shaping the response to Darwin's hypothesis, with religious anxieties overlapping with a whole host of other cultural and scientific considerations. An absorbing study, Of Apes and Ancestors sheds light on the origins of a debate that continues, unresolved, to this day.
Of Human Born: Fetal Lives, 1800–1950
by Caroline ArniA new history of the concept of fetal life in the human sciencesAt a time when the becoming of a human being in a woman&’s body has, once again, become a fraught issue—from abortion debates and surrogacy controversies to prenatal diagnoses and assessments of fetal risk—Of Human Born presents the largely unknown history of how the human sciences came to imagine the unborn in terms of &“life before birth.&”Caroline Arni shows how these sciences created the concept of &“fetal life&” by way of experimenting on animals, pregnant women, and newborns; how they worried about the influence of the expectant mother&’s living conditions; and how they lingered on the question of the beginnings of human subjectivity. Such were the concerns of physiologists, pediatricians, psychologists, and psychoanalysts as they advanced the novel discipline of embryology while, at the same time, grappling with age-old questions about the coming-into-being of a human person. Of Human Born thus draws attention to the fundamental way in which modern approaches to the unborn have been intertwined with the configuration of &“the human&” in the age of scientific empiricism.Arni revises the narrative that the &“modern embryo&” is quintessentially an embryo disembedded from the pregnant woman&’s body. On the contrary, she argues that the concept of fetal life cannot be separated from its dependency on the maternal organism, countering the rhetorical discourses that have fueled the recent rollback of abortion rights in the United States.
Of Ice and Men: How We've Used Cold to Transform Humanity
by Fred HoggeAn exploration of humanity&’s relationship with ice since the dawn of civilization, Of Ice and Men reminds us that only by understanding this unique substance can we save the ice on our planet—and perhaps ourselves.Ice tells a story. It writes it in rock. It lays it down, snowfall by snowfall at the ends of the earth where we may read it like the rings on a tree. It tells our planet&’s geological and climatological tale. Ice tells another story too: a story about us. It is a tale packed with swash-buckling adventure and improbable invention, peopled with driven, eccentric, often brilliant characters. It tells how our species has used ice to reshape the world according to our needs and our desires: how we have survived it, harvested it, traded it, bent science to our will to make it—and how in doing so we have created globe-spanning infrastructures that are entirely dependent upon it. And even after we have done all that, we take ice so much for granted that we barely notice it. Ice has supercharged the modern world. It has allowed us to feed ourselves and cure ourselves in ways unimaginable two hundred years ago. It has enabled the global population to rise from less than 1 billion to nearly 7½ billion—which just happens to cover the same period of time as humanity has harvested, manufactured, and distributed ice on an industrial scale. And yet the roots of our fascination with ice and its properties run much deeper than the recent past.
Of Matters Great and Small
by Isaac AsimovMy beautiful, blonde-haired, blue-eyed daughter had not been at college long when word reached her that a certain young man W.15 dying to meet her, presumably, she was given to understand, to feast his eyes on her beauty. After some ladylike show of reluctance, Robyn agreed to allow the meeting. In came the young man, eyes wide. "Tell me," he said, choking a bit, "are you really the daughter of Isaac Asimov?" Now, if I had started this essay with: "The two chief methods by which a radioactive nucleus can break down involve, one..." would you have plunged in quite as rapidly as you would with a beginning like: "My beautiful, blonde-haired, blue-eyed daughter "? Tell the truth...
Of Maybugs and Men: A History and Philosophy of the Sciences of Homosexuality
by Pieter R. Adriaens Andreas De BlockA much-needed exploration of the history and philosophy of scientific research into male homosexuality. Questions about the naturalness or unnaturalness of homosexuality are as old as the hills, and the answers have often been used to condemn homosexuals, their behaviors, and their relationships. In the past two centuries, a number of sciences have involved themselves in this debate, introducing new vocabularies, theories, arguments, and data, many of which have gradually helped tip the balance toward tolerance and even acceptance. In this book, philosophers Pieter R. Adriaens and Andreas De Block explore the history and philosophy of the gay sciences, revealing how individual and societal values have colored how we think about homosexuality. The authors unpack the entanglement of facts and values in studies of male homosexuality across the natural and human sciences and consider the extent to which science has mitigated or reinforced homonegative mores. The focus of the book is on homosexuality’s assumed naturalness. Geneticists rephrased naturalness as innateness, claiming that homosexuality is innate—colloquially, that homosexuals are born gay. Zoologists thought it a natural affair, documenting its existence in myriad animal species, from maybugs to men. Evolutionists presented homosexuality as the product of natural selection and speculated about its adaptive value. Finally, psychiatrists, who initially pathologized homosexuality, eventually appealed to its naturalness or innateness to normalize it. Discussing findings from an array of sciences—comparative zoology, psychiatry, anthropology, evolutionary biology, social psychology, developmental biology, and machine learning—this book is essential reading for anyone interested in what science has to say about homosexuality.

Of Men and Numbers: The Story of the Great Mathematicians (Dover Books On Mathematics Ser.)
by Jane MuirWhile mathematics itself may be a formidable subject for many, the lives and accomplishments of history’s greatest mathematicians—from Pythagoras to Cantor—offer fascinating reading.In this delightful and informative recounting, for example, we learn how Pascal’s life was abruptly changed by a family of fanatical bonesetters, how Descartes was influenced by three dreams, and how the scholarly Swiss Leonhard Euler (whose famous conjecture was finally disproved in 1959, after 177 years) almost ended up in the Russian navy.Here, too, are Cardano, the gambler who becomes the 16th century’s most fashionable doctor; Archimedes, Newton, and Gauss, often considered the three greatest mathematicians of all times; Lobatchevsky, the inventor of non-Euclidean geometry; and the tragic Galois, a founder of modern higher algebra.In addition to a wealth of interesting and informative anecdotes, presented in a delightfully conversational style, the author offers lucid, accessible explanations of these thinkers’ invaluable contributions to the edifice of modern mathematical thought and to man’s understanding of himself and his universe.—Print ed.
Of Monsters and Madness
by Jessica VerdayA romantic, historical retelling of classic Gothic horror featuring Edgar Allan Poe and his character Annabel Lee, from a New York Times best-selling author.Annabel Lee is summoned from Siam to live with her father in 1820's Philadelphia shortly after her mother's death, but an unconventional upbringing makes her repugnant to her angry, secretive father.Annabel becomes infatuated with her father's assistant Allan, who dabbles in writing when he's not helping with medical advancements. But in darker hours, when she's not to be roaming the house, she encounters the devilish assistant Edgar, who bears an uncanny resemblance to Allan, and who others insist doesn't exist. A rash of murders across Philadelphia, coupled with her father's strange behavior, leads Annabel to satisfy her curiosity and uncover a terrible truth: Edgar and Allan are two halves of the same person - and they are about to make the crimes detailed in Allan's stories come to life. Unless Annabel stops them.
Of Orcas and Men: What Killer Whales Can Teach Us
by David NeiwertA celebrated journalist's eye-opening history of orcas, and an exploration of their relationship with human beings, Of Orcas and Men does for whales what Barry Lopez did for wolves The orca--otherwise known as the killer whale--is one of earth's most intelligent animals. Remarkably sophisticated, orcas have languages and cultures and even long-term memories, and their capacity for echolocation is nothing short of a sixth sense. They are also benign and gentle, which makes the story of the captive-orca industry--and the endangerment of their population in Puget Sound--that much more damning. In Of Orcas and Men, a marvelously compelling mix of cultural history, environmental reporting, and scientific research, David Neiwert explores an extraordinary species and its occasionally fraught relationship with human beings. Beginning with their role in myth and contemporary popular culture, Neiwert shows how killer whales came to capture our imaginations, and brings to life the often catastrophic environmental consequences of that appeal. In the tradition of Barry Lopez's classic Of Wolves and Men, David Neiwert's book is a triumph of reporting, observation, and research, and a powerful tribute to one of the animal kingdom's most remarkable members.

Of Sheep, Oranges, and Yeast: A Multispecies Impression
by Julian YatesIn what senses do animals, plants, and minerals “write”? How does their “writing” mark our livesour past, present, and future? Addressing such questions with an exhilarating blend of creative flair and theoretical depth, Of Sheep, Oranges, and Yeast traces how the lives of, yes, sheep, oranges, gold, and yeast mark the stories of those animals we call “human.”Bringing together often separate conversations in animal studies, plant studies, ecotheory, and biopolitics, Of Sheep, Oranges, and Yeast crafts scripts for literary and historical study that embrace the fact that we come into being through our relations to other animal, plant, fungal, microbial, viral, mineral, and chemical actors. The book opens and closes in the company of a Shakespearean character talking through his painful encounter with the skin of a lamb (in the form of parchment). This encounter stages a visceral awareness of what Julian Yates names a “multispecies impression,” the way all acts of writing are saturated with the “writing” of other beings. Yates then develops a multimodal reading strategy that traces a series of anthropo-zoo-genetic figures that derive from our comaking with sheep (keyed to the story of biopolitics), oranges (keyed to economy), and yeast (keyed to the notion of foundation or infrastructure). Working with an array of materials (published and archival), across disciplines and historical periods (Classical to postmodern), the book allows sheep, oranges, and yeast to dictate their own chronologies and plot their own stories. What emerges is a methodology that fundamentally alters what it means to read in the twenty-first century.
Of Sound Mind: How Our Brain Constructs a Meaningful Sonic World
by Nina KrausHow sound leaves a fundamental imprint on who we are.Making sense of sound is one of the hardest jobs we ask our brains to do. In Of Sound Mind, Nina Kraus examines the partnership of sound and brain, showing for the first time that the processing of sound drives many of the brain's core functions. Our hearing is always on--we can't close our ears the way we close our eyes--and yet we can ignore sounds that are unimportant. We don't just hear; we engage with sounds. Kraus explores what goes on in our brains when we hear a word--or a chord, or a meow, or a screech. Our hearing brain, Kraus tells us, is vast. It interacts with what we know, with our emotions, with how we think, with our movements, and with our other senses. Auditory neurons make calculations at one-thousandth of a second; hearing is the speediest of our senses. Sound plays an unrecognized role in both healthy and hurting brains. Kraus explores the power of music for healing as well as the destructive power of noise on the nervous system. She traces what happens in the brain when we speak another language, have a language disorder, experience rhythm, listen to birdsong, or suffer a concussion. Kraus shows how our engagement with sound leaves a fundamental imprint on who we are. The sounds of our lives shape our brains, for better and for worse, and help us build the sonic world we live in.
Of Stars and Men: Reminiscences of an Astronomer
by Zdenek KopalThe twentieth century has been a remarkable epoch in the affairs of men, and this is no less true of astronomy, at once the oldest and most modern of the sciences. Sky watchers at the beginning of the century measured positions and predicted celestial motions in faithful but uninspired homage to the Muse Urania; nowadays, their descendents call on all the resources of modern science to probe the nature and evolution of a bewildering range of celestial objects. Man has even set out to call personally on his nearest neighbours in space. Professor Zdenek Kopal has lived and practised astronomy throughout this efflorescence of his subject. Born in Czechoslovakia just before the outbreak of the Great War, and educated in the classical European tradition, he knows well the days when scholars commanded such respect that astronomical congresses would be visited by Heads of State. Yet within his own lifetime, he has himself been recruited to play an important role in scientific preparations for a manned Moon landing. He has known and worked with some of the most highly respected practitioners of Modern Astromomy: Russell, Shapley, Urey in the United States, Eddington in Britain. His fine eye for detail, coupled with his strong sense of history, enable him to unfold through his personal recollections the development of his subject across the social changes of two world wars. Inspired by his grandfather, who would think nothing of walking sixty miles to theatrical performance, the young Kopal acquired a Wanderlust that has taken him in his career more than a dozen times rond the world. He has visited the most ancient observatories, observed solar eclipses in Japan and Java, helped to establish new institutions in Iraq and India, and commuted for many years between the Old and New Worlds. He has toiled in every corner of his chosen vinyard: as observer, outstanding theoretician, populariser, editor and teacher. During his thirty years as Professor of Astronomy at Manchester, he
Of Time and Turtles: Mending the World, Shell by Shattered Shell
by Sy MontgomeryNational Book Award finalist for The Soul of an Octopus and New York Times bestseller Sy Montgomery turns her journalistic curiosity to the wonder and wisdom of our long-lived cohabitants—turtles—and through their stories of hope and rescue, reveals to us astonishing new perspectives on time and healing.When acclaimed naturalist Sy Montgomery and wildlife artist Matt Patterson arrive at Turtle Rescue League, they are greeted by hundreds of turtles recovering from injury and illness. Endangered by cars and highways, pollution and poachers, these turtles—with wounds so severe that even veterinarians would have dismissed them as fatal—are given a second chance at life. The League’s founders, Natasha and Alexxia, live by one motto: Never give up on a turtle.But why turtles? What is it about them that inspires such devotion? Ancient and unhurried, long-lived and majestic, their lineage stretches back to the time of the dinosaurs. Some live to two hundred years, or longer. Others spend months buried under cold winter water. Montgomery turns to these little understood yet endlessly surprising creatures to probe the eternal question: How can we make peace with our time?In pursuit of the answer, Sy and Matt immerse themselves in the delicate work of protecting turtle nests, incubating eggs, rescuing sea turtles, and releasing hatchlings to their homes in the wild. We follow the snapping turtle Fire Chief on his astonishing journey as he battles against injuries incurred by a truck.Hopeful and optimistic, Of Time and Turtles is an antidote to the instability of our frenzied world. Elegantly blending science, memoir, philosophy, and drawing on cultures from across the globe, this compassionate portrait of injured turtles and their determined rescuers invites us all to slow down and slip into turtle time.Perfect gift for nature lovers.Includes a signature of photos plus stunning, photo-realistic full color paintings and black-and-white chapter opener art by wildlife artist Matt Patterson.Read more books by Sy Montgomery such as How to Be a Good Creature and The Soul of an Octopus.Don't miss The Book of Turtles for children.
Of Time, Passion, and Knowledge: Reflections On The Strategy Of Existence
by Julius Thomas Fraser"Only a wayfarer born under unruly stars would attempt to put into practice in our epoch of proliferating knowledge the Heraclitean dictum that `men who love wisdom must be inquirers into very many things indeed.'" Thus begins this remarkable interdisciplinary study of time by a master of the subject. And while developing a theory of "time as conflict," J. T. Fraser does offer "many things indeed"--an enormous range of ideas about matter, life, death, evolution, and value.
Of Walden Pond: Henry David Thoreau, Frederic Tudor, and the Pond Between
by Lesa Cline-RansomeFrom the award-winning author of Before She Was Harriet comes another work of lyrical beauty, the story of Henry David Thoreau and businessman Frederic Tudor—and a changing world.Thoreau and Tudor could not have been more different from each other. Yet both shared the bounties of Walden Pond and would change the course of history through their writings and innovations. This study in opposites contrasts the austere philosopher with the consummate capitalist (whose innovations would change commercial ice harvesting and home refrigerators) to show how two seemingly conflicting American legacies could be built side by side. Oddball/ tax dodger/ nature lover/ dreamer/ That&’s what they called/ Thoreau.Bankrupt/ disgrace/ good for nothing/ dreamer/ That&’s what they called/ Tudor. Celebrated author Lesa Cline-Ransome takes her magnificent talent for research and detail to plumb the depths of these two history-makers. The graceful text is paired with Ashley Benham-Yazdani&’s period accurate watercolor and pencil artwork. In winter, readers see Tudor&’s men sawing through the ice, the workhorses dragging the ice, and Thoreau observing it all; in spring, summer, and fall, the ice continues its journey across the globe with Thoreau and Tudor writing and reflecting in their respective diaries. An Author&’s Note, which explores how Thoreau&’s writings influenced such figures as Martin Luther King Jr., Robert Frost, and Mohandas Gandhi, is included.
Of Wolves and Men
by Barry LopezNational Book Award Finalist: A &“brilliant&” study of the science and mythology of the wolf by the New York Times–bestselling author of Arctic Dreams (The Washington Post). When John Fowles reviewed Of Wolves and Men, he called it &“A remarkable book, both biologically absorbing and humanly rich, and one that should be read by every concerned American.&” In this National Book Award–shortlisted work, literary master Barry Lopez guides us through the world of the wolf and our often-mistaken perceptions of another species&’ place on our shared planet. Throughout the centuries, the wolf has been a figure of fascination and mystery, and a major motif in literature and myth. Inspiring fear and respect, the creature has long exerted a powerful influence on the human imagination. Of Wolves and Men takes the reader into the world of the Canis lupus and its relationship to humankind through the ages. Lopez draws on science, history, mythology, and his own field research to present a compelling portrait of wolves both real and imagined, dispelling our fear of them while celebrating their place in our history, legends, and hearts. This ebook features an illustrated biography of Barry Lopez including rare images and never-before-seen documents from the author&’s personal collection.
Ofdm Based Relay Systems for Future Wireless Communications (River Publishers Series In Communications Ser.)
by Milica Pejanovic-Djurisic Enis Kocan Ramjee PrasadRelay systems have become a subject of intensive research interest over the recent years, as it is recognized that they can improve performances and extend the coverage area of wireless communication systems. Special attention has been dedicated to them since the proposal appeared for their implementation in mobile cellular systems. Numerous researches conducted after that proposal have enabled incorporation of OFDM based relay systems in both accepted standards for IMT-Advanced systems. Nowadays, researches are ongoing with the aim to define new solutions for performance improvement of the standardized OFDM relay systems for cellular networks and one of the interesting solutions is implementation of subcarrier permutation (SCP) at the relay (R) station.The book OFDM based relay systems for future wireless communications presents a comprehensive research results in analyzing behavior and performance of the OFDM based relay systems with SCP.
