Download or read book First Signals written by John Tyler Bonner and published by Princeton University Press. This book was released on 2009-09-11 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enormous recent success of molecular developmental biology has yielded a vast amount of new information on the details of development. So much so that we risk losing sight of the underlying principles that apply to all development. To cut through this thicket, John Tyler Bonner ponders a moment in evolution when development was at its most basic--the moment when signaling between cells began. Although multicellularity arose numerous times, most of those events happened many millions of years ago. Many of the details of development that we see today, even in simple organisms, accrued over a long evolutionary timeline, and the initial events are obscured. The relatively uncomplicated and easy-to-grow cellular slime molds offer a unique opportunity to analyze development at a primitive stage and perhaps gain insight into how early multicellular development might have started. Through slime molds, Bonner seeks a picture of the first elements of communication between cells. He asks what we have learned by looking at their developmental biology, including recent advances in our molecular understanding of the process. He then asks what is the most elementary way that polarity and pattern formation can be achieved. To find the answer, he uses models, including mathematical ones, to generate insights into how cell-to-cell cooperation might have originated. Students and scholars in the blossoming field of the evolution of development, as well as evolutionary biologists generally, will be interested in what Bonner has to say about the origins of multicellular development--and thus of the astounding biological complexity we now observe--and how best to study it.

Book excerpt: First demonstrated in 1928, color television remained little more than a novelty for decades as the industry struggled with the considerable technical, regulatory, commercial, and cultural complications posed by the medium. Only fully adopted by all three networks in the 1960s, color television was imagined as a new way of seeing that was distinct from both monochrome television and other forms of color media. It also inspired compelling popular, scientific, and industry conversations about the use and meaning of color and its effects on emotions, vision, and desire. In Bright Signals Susan Murray traces these wide-ranging debates within and beyond the television industry, positioning the story of color television, which was replete with false starts, failure, and ingenuity, as central to the broader history of twentieth-century visual culture. In so doing, she shows how color television disrupted and reframed the very idea of television while it simultaneously revealed the tensions about technology's relationship to consumerism, human sight, and the natural world.

Download or read book Signals written by Joel Rothschild and published by New World Library. This book was released on 2011-02-20 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joel Rothschild and his friend Albert, both HIV positive, made a pact: whoever died first would attempt to "signal" the other from beyond. Joel wasn't sure he believed in psychic abilities, but from the day Albert died he began receiving messages. One message led Joel to a note Albert had left for him before he died. Another message told Joel to hang in there when he became sick, that he would get well - and he did.Albert's messages have changed not only Joel's life but the lives of many others who have been helped by messages Joel has delivered to them. Their stories and Joel's psychic awakening - a transformation from cynic to believer - are both amazing and reassuring.

This book was released on 2017-12-20 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: College Aspirations and Access in Working Class Rural Communities: The Mixed Signals, Challenges, and New Language First-Generation Students Encounter explores how a working class, rural environment influences rural students’ opportunities to pursue higher education and engage in the college choice process. Based on a case study with accounts from rural high school students and counselors, this book examines how these communities perceive higher education and what challenges arise for both rural students and counselors. The book addresses how college knowledge and university jargon illustrate the gap between rural cultural capital and higher education cultural capital. Insights about approaches to reduce barriers created by college knowledge and university jargon are shared and strategies for offering rural students pathways to learn academic language and navigate higher education are presented for both secondary and higher education institutions.
Download or read book Signals written by Tim Gautreaux and published by Vintage. This book was released on 2017-01-17 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: A widely celebrated novelist gives us a generous collection of exhilarating short stories, proving that he is a master of this genre as well. Once again, "he reminds us," wrote The Miami Herald, "that great writing is a timeless art." After the stunning historical novels The Clearing and The Missing, Tim Gautreaux now ranges freely through contemporary life with twelve new stories and eight from previous collections. Most are set in his beloved Louisiana, many hard by or on the Mississippi River, others in North Carolina and even in midwinter Minnesota. But generally it's heat, humidity, and bugs that beset his people as they wrestle with affairs of the heart, matters of faith, and the pros and cons of tight-knit communities--a remarkable cast of characters, primarily of the working class, proud and knowledgeable about the natural or mechanical world, their lives marked by a prized stereo or a magical sewing machine retrieved from a locked safe, boats and card games and casinos, grandparents and grandchildren and those in between, their experiences leading them to the ridiculous or the scarifying or the sublime; most of them striving for what's right and good, others tearing off in the opposite direction.
Download or read book The British Army and Signals Intelligence During the First World War written by John Ferris and published by Alan Sutton Publishing. This book was released on 1992 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Historians have paid little attention to the British Army's experience with signals intelligence during the First World War. However, this was one of the Army's most important sources of information about crucial matters such as the order of battle and intentions of the German and Turkish Armies. Britain's successes and failures in signals intelligence profoundly affected battles ranging from the race for the Channel Ports, first Somme, third Gaza and Amiens, among many others." "While efforts to weed the records on these topics have created major gaps in the sources, surviving evidence throws an entirely new light on the British Army in the Great War. It allows one to trace the evolution of the Army's signals intelligence organisations, to determine many of their successes and failures, to show how this intelligence affected various operations and, indeed, to demonstrate that signals intelligence influenced the operations of the British Army as much as those of the Royal Navy." "The material reproduced in this volume includes excerpts from reports by Army Headquarters in France, Italy and Mesopotamia and the Military Intelligence Directorate. It includes the memorandum "Enemy Codes and their Solution" by the G.H.Q. codebreaking section in January 1918, which is one of the two best sources known to exist about the techniques of "codebreaking"; surviving reports on the enemy radio networks in the Balkans and Anatolian Turkey, which are the most illuminating evidence from any theatre on the approach toward "traffic analysis" and a report on the breaking of German and Turkish Army ciphers in Mesopotamia during 1917, which is the best source known about the techniques of "cryptanalysis" used by an Army in the Great War."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book excerpt: SIGNALS INTELLIGENCE, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War.In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty’s famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers."SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." THE ST ERMIN'S HOTEL INTELLIGENCE BOOK OF THE YEAR AWARD 2014.

Download or read book Brain Signals written by Risto J. Ilmoniemi and published by MIT Press. This book was released on 2019-05-28 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unified treatment of the generation and analysis of brain-generated electromagnetic fields. In Brain Signals, Risto Ilmoniemi and Jukka Sarvas present the basic physical and mathematical principles of magnetoencephalography (MEG) and electroencephalography (EEG), describing what kind of information is available in the neuroelectromagnetic field and how the measured MEG and EEG signals can be analyzed. Unlike most previous works on these topics, which have been collections of writings by different authors using different conventions, this book presents the material in a unified manner, providing the reader with a thorough understanding of basic principles and a firm basis for analyzing data generated by MEG and EEG. The book first provides a brief introduction to brain states and the early history of EEG and MEG, describes the generation of electromagnetic fields by neuronal activity, and discusses the electromagnetic forward problem. The authors then turn to EEG and MEG analysis, offering a review of linear and matrix algebra and basic statistics needed for analysis of the data, and presenting several analysis methods: dipole fitting; the minimum norm estimate (MNE); beamforming; the multiple signal classification algorithm (MUSIC), including RAP-MUSIC with the RAP dilemma and TRAP-MUSIC, which removes the RAP dilemma; independent component analysis (ICA); and blind source separation (BSS) with joint diagonalization.

Download or read book Practical Signals Theory with MATLAB Applications written by Richard J. Tervo and published by John Wiley & Sons. This book was released on 2013-02-11 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical Signals Theory with MATLAB Applications is organized around applications, first introducing the actual behavior of specific signals and then using them to motivate the presentation of mathematical concepts. Tervo sequences the presentation of the major transforms by their complexity: first Fourier, then Laplace, and finally the z-transform. The goal is to help students who can’t visualize phenomena from an equation to develop their intuition and learn to analyze signals by inspection. Finally, most examples and problems are designed to use MATLAB, making the presentation more in line with modern engineering practice.
