Reconfigurable Intelligent Surface-Enabled Integrated Sensing and Communication in 6G (Wireless Networks)
Par Xiaoling Hu, Chenxi Liu, Mugen Peng, Caijun Zhong. 2024
As the main trend and key enabling technology for next-generation wireless networks (i.e., 6G), integrated sensing and communication (ISAC) can…
effectively improve spectrum efficiency, hardware efficiency, and information processing efficiency. However, it faces several deficiencies, including limited coverage due to high-frequency signals and limited communication-sensing performance due to uncontrollable wireless environments. Reconfigurable intelligent surface (RIS) provides novel dimensions to address these deficiencies by intelligently manipulating the wireless propagation environment in an energy- and hardware-efficient manner. RIS-enabled ISAC is expected to comprehensively promote the multi-dimensional performance of 6G, such as communication capacity, sensing accuracy, and coverage. Nevertheless, to fully realize its potential, one needs to figure out the impacts of RIS on joint communication and sensing performance and tackle new technical challenges in beamforming design and signal processing. The goal of this book, therefore, is to deliver a thorough understanding of RIS-enabled ISAC from three perspectives: performance analysis, beamforming design, and signal processing. Specifically, the authors provide a brief introduction to RIS-enabled ISAC, including basic concepts, motivations, potential application scenarios, and an overview of the state-of-the-art research on RIS-enabled ISAC. The theoretical performance analytical frameworks of RIS-enabled ISAC and their corresponding results are also discussed. Based on this, several critical issues are identified and elaborated on, including signal processing technologies such as angle and Delay-Doppler information acquisition, and air interface technologies such as beamforming designs. Finally, the book concludes with future trends and open issues for further research.The book would be beneficial for researchers, graduate students, and industry professionals who wish to gain a comprehensive understanding of the latest developments and challenges in RIS-enabled ISAC. By providing insights into the potential of RIS-enabled ISAC and the technical challenges that need to be addressed, the book can aid in the development of practical solutions for next-generation wireless networks and contribute to the advancement of the field of wireless communications.Unser Platz im Universum: Astronomie anhand alter Entdeckungen verstehen
Par Sun Kwok. 2023
Wenn Sie schon immer die Grundprinzipien der Astronomie und der Himmelsbewegungen verstehen wollten, sollten Sie dieses Buch lesen. Anhand von…
Bildern des Himmels, die von verschiedenen Orten der Erde aus beobachtet wurden, sowie von Zeichnungen alter astronomischer Methoden und Werkzeuge erzählt Prof. Sun Kwok diese Geschichte auf unterhaltsame und faszinierende Weise.Seit den Anfängen der menschlichen Zivilisation haben sich die Menschen Gedanken über die Struktur des Kosmos und unseren Platz im Universum gemacht. Vor mehr als 2.000 Jahren wussten unsere Vorfahren bereits, dass die Jahreszeiten ungleichmäßig verlaufen, dass die Erde frei im Raum schwebt, und dass es Sterne gibt, die sie nicht sehen können. Aus ihren Himmelsbeobachtungen schlossen sie, dass die Erde rund ist. Mit einfachen Werkzeugen und mathematischen Methoden bestimmten die Astronomen der Antike die Größe der Erde und des Mondes, die Entfernung zum Mond und die Länge der Monate und des Jahres genau.Mit einem raffinierten Gerät, der Armillarsphäre, konnten die griechischen Astronomen die Zeiten des Sonnenaufgangs und des Sonnenuntergangs an jedem Tag des Jahres und an jedem Ort der Erde vorhersagen. Sie entwickelten ausgeklügelte mathematische Modelle, um die Bewegungen des Mars für Hunderte von Jahren in die Zukunft vorauszusagen.Finden Sie heraus, wie die antiken Beobachter diese bemerkenswerten Leistungen vollbrachten. Mit minimalem Einsatz von Mathematik zeichnet dieses Buch die Spuren unserer Vorfahren nach, erklärt ihre intellektuelle Reise in einfachen Worten und erforscht die philosophischen Bedeutungen dieser Entdeckungen.Looking Inside the Brain: The Power of Neuroimaging
Par Denis Le Bihan. 2015
The remarkable story of how today's brain scanning techniques were developed, told by one of the field's pioneersIt is now…
possible to witness human brain activity while we are talking, reading, or thinking, thanks to revolutionary neuroimaging techniques like magnetic resonance imaging (MRI). These groundbreaking advances have opened infinite fields of investigation—into such areas as musical perception, brain development in utero, and faulty brain connections leading to psychiatric disorders—and have raised unprecedented ethical issues. In Looking Inside the Brain, one of the leading pioneers of the field, Denis Le Bihan, offers an engaging account of the sophisticated interdisciplinary research in physics, neuroscience, and medicine that have led to the remarkable neuroimaging methods that give us a detailed look into the human brain.Introducing neurological anatomy and physiology, Le Bihan walks readers through the historical evolution of imaging technology—from the x-ray and CT scan to the PET scan and MRI—and he explains how neuroimaging uncovers afflictions like stroke or cancer and the workings of higher-order brain activities, such as language skills. Le Bihan also takes readers on a behind-the-scenes journey through NeuroSpin, his state-of-the-art neuroimaging laboratory, and goes over the cutting-edge scanning devices currently being developed. Considering what we see when we look at brain images, Le Bihan weighs what might be revealed about our thoughts and unconscious, and discusses how far this technology might go in the future.Beautifully illustrated in color, Looking Inside the Brain presents the trailblazing story of the scanning techniques that provide keys to previously unimagined knowledge of our brains and our selves.Heavenly Mathematics: The Forgotten Art of Spherical Trigonometry

Par Geerat Vermeij. 2004
From humans to hermit crabs to deep water plankton, all living things compete for locally limiting resources. This universal truth…
unites three bodies of thought--economics, evolution, and history--that have developed largely in mutual isolation. Here, Geerat Vermeij undertakes a groundbreaking and provocative exploration of the facts and theories of biology, economics, and geology to show how processes common to all economic systems--competition, cooperation, adaptation, and feedback--govern evolution as surely as they do the human economy, and how historical patterns in both human and nonhuman evolution follow from this principle. Using a wealth of examples of evolutionary innovations, Vermeij argues that evolution and economics are one. Powerful consumers and producers exercise disproportionate controls on the characteristics, activities, and distribution of all life forms. Competition-driven demand by consumers, when coupled with supply-side conditions permitting economic growth, leads to adaptation and escalation among organisms. Although disruptions in production halt or reverse these processes temporarily, they amplify escalation in the long run to produce trends in all economic systems toward greater power, higher production rates, and a wider reach for economic systems and their strongest members. Despite our unprecedented power to shape our surroundings, we humans are subject to all the economic principles and historical trends that emerged at life's origin more than 3 billion years ago. Engagingly written, brilliantly argued, and sweeping in scope, Nature: An Economic History shows that the human institutions most likely to preserve opportunity and adaptability are, after all, built like successful living things.How the sciences of the mind can advance the study of religionThe essence of religion was once widely thought to…
be a unique form of experience that could not be explained in neurological, psychological, or sociological terms. In recent decades scholars have questioned the privileging of the idea of religious experience in the study of religion, an approach that effectively isolated the study of religion from the social and natural sciences. Religious Experience Reconsidered lays out a framework for research into religious phenomena that reclaims experience as a central concept while bridging the divide between religious studies and the sciences.Ann Taves shifts the focus from "religious experience," conceived as a fixed and stable thing, to an examination of the processes by which people attribute meaning to their experiences. She proposes a new approach that unites the study of religion with fields as diverse as neuroscience, anthropology, sociology, and psychology to better understand how these processes are incorporated into the broader cultural formations we think of as religious or spiritual. Taves addresses a series of key questions: how can we set up studies without obscuring contestations over meaning and value? What is the relationship between experience and consciousness? How can research into consciousness help us access and interpret the experiences of others? Why do people individually or collectively explain their experiences in religious terms? How can we set up studies that allow us to compare experiences across times and cultures?Religious Experience Reconsidered demonstrates how methods from the sciences can be combined with those from the humanities to advance a naturalistic understanding of the experiences that people deem religious.How Did the First Stars and Galaxies Form? (Princeton Frontiers in Physics #1)
Par Abraham Loeb. 2010
A concise introduction to cosmology and how light first emerged in the universeThough astrophysicists have developed a theoretical framework for…
understanding how the first stars and galaxies formed, only now are we able to begin testing those theories with actual observations of the very distant, early universe. We are entering a new and exciting era of discovery that will advance the frontiers of knowledge, and this book couldn't be more timely. It covers all the basic concepts in cosmology, drawing on insights from an astronomer who has pioneered much of this research over the past two decades.Abraham Loeb starts from first principles, tracing the theoretical foundations of cosmology and carefully explaining the physics behind them. Topics include the gravitational growth of perturbations in an expanding universe, the abundance and properties of dark matter halos and galaxies, reionization, the observational methods used to detect the earliest galaxies and probe the diffuse gas between them—and much more.Cosmology seeks to solve the fundamental mystery of our cosmic origins. This book offers a succinct and accessible primer at a time when breathtaking technological advances promise a wealth of new observational data on the first stars and galaxies.Provides a concise introduction to cosmologyCovers all the basic conceptsGives an overview of the gravitational growth of perturbations in an expanding universeExplains the process of reionizationDescribes the observational methods used to detect the earliest galaxiesIn brute-force struggles for survival, such as the two World Wars, disorganization and divisions within an enemy alliance are to…
one's own advantage. However, most international security politics involve coercive diplomacy and negotiations short of all-out war. Worse Than a Monolith demonstrates that when states are engaged in coercive diplomacy--combining threats and assurances to influence the behavior of real or potential adversaries--divisions, rivalries, and lack of coordination within the opposing camp often make it more difficult to prevent the onset of conflict, to prevent existing conflicts from escalating, and to negotiate the end to those conflicts promptly. Focusing on relations between the Communist and anti-Communist alliances in Asia during the Cold War, Thomas Christensen explores how internal divisions and lack of cohesion in the two alliances complicated and undercut coercive diplomacy by sending confusing signals about strength, resolve, and intent. In the case of the Communist camp, internal mistrust and rivalries catalyzed the movement's aggressiveness in ways that we would not have expected from a more cohesive movement under Moscow's clear control. Reviewing newly available archival material, Christensen examines the instability in relations across the Asian Cold War divide, and sheds new light on the Korean and Vietnam wars. While recognizing clear differences between the Cold War and post-Cold War environments, he investigates how efforts to adjust burden-sharing roles among the United States and its Asian security partners have complicated U.S.-China security relations since the collapse of the Soviet Union.Advances in Plant Biotechnology: In Vitro Production of Secondary Metabolites of Industrial Interest (Food Biotechnology and Engineering)

States dropped the bomb, and physicists were forced to contemplate disquieting questions about their roles and responsibilities. When the Cold War followed, they were confronted with political demands for their loyalty and McCarthyism's threats to academic freedom. By examining how J. Robert Oppenheimer and Hans A. Bethe—two men with similar backgrounds but divergent aspirations and characters—struggled with these moral dilemmas, one of our foremost historians of physics tells the story of modern physics, the development of atomic weapons, and the Cold War.Oppenheimer and Bethe led parallel lives. Both received liberal educations that emphasized moral as well as intellectual growth. Both were outstanding theoreticians who worked on the atom bomb at Los Alamos. Both advised the government on nuclear issues, and both resisted the development of the hydrogen bomb. Both were, in their youth, sympathetic to liberal causes, and both were later called to defend the United States against Soviet communism and colleagues against anti-Communist crusaders. Finally, both prized scientific community as a salve to the apparent failure of Enlightenment values.Yet their responses to the use of the atom bomb, the testing of the hydrogen bomb, and the treachery of domestic politics differed markedly. Bethe, who drew confidence from scientific achievement and integration into the physics community, preserved a deep integrity. By accepting a modest role, he continued to influence policy and contributed to the nuclear test ban treaty of 1963. In contrast, Oppenheimer first embodied a new scientific persona—the scientist who creates knowledge and technology affecting all humanity and boldly addresses their impact—and then could not carry its burden. His desire to retain insider status, combined with his isolation from creative work and collegial scientific community, led him to compromise principles and, ironically, to lose prestige and fall victim to other insiders.S. S. Schweber draws on his vast knowledge of science and its history—in addition to his unique access to the personalities involved—to tell a tale of two men that will enthrall readers interested in science, history, and the lives and minds of great thinkers.Seeds of Amazonian Plants (Princeton Field Guides #66)

Par Matthew M. Briones. 2012
Following Japan's attack on Pearl Harbor in 1941, the U.S. government rounded up more than one hundred thousand Japanese Americans…
and sent them to internment camps. One of those internees was Charles Kikuchi. In thousands of diary pages, he documented his experiences in the camps, his resettlement in Chicago and drafting into the Army on the eve of Hiroshima and Nagasaki, and his postwar life as a social worker in New York City. Kikuchi's diaries bear witness to a watershed era in American race relations, and expose both the promise and the hypocrisy of American democracy. Jim and Jap Crow follows Kikuchi's personal odyssey among fellow Japanese American intellectuals, immigrant activists, Chicago School social scientists, everyday people on Chicago's South Side, and psychologically scarred veterans in the hospitals of New York. The book chronicles a remarkable moment in America's history in which interracial alliances challenged the limits of the elusive democratic ideal, and in which the nation was forced to choose between civil liberty and the fearful politics of racial hysteria. It was an era of world war and the atomic bomb, desegregation in the military but Jim and Jap Crow elsewhere in America, and a hopeful progressivism that gave way to Cold War paranoia. Jim and Jap Crow looks at Kikuchi's life and diaries as a lens through which to observe the possibilities, failures, and key conversations in a dynamic multiracial America.Food Webs (Monographs in Population Biology #50)
Par Kevin S. McCann. 2012
Human impacts are dramatically altering our natural ecosystems but the exact repercussions on ecological sustainability and function remain unclear. As…
a result, food web theory has experienced a proliferation of research seeking to address these critical areas. Arguing that the various recent and classical food web theories can be looked at collectively and in a highly consistent and testable way, Food Webs synthesizes and reconciles modern and classical perspectives into a general unified theory. Kevin McCann brings together outcomes from population-, community-, and ecosystem-level approaches under the common currency of energy or material fluxes. He shows that these approaches--often studied in isolation--all have the same general implications in terms of population dynamic stability. Specifically, increased fluxes of energy or material tend to destabilize populations, communities, and whole ecosystems. With this understanding, stabilizing structures at different levels of the ecological hierarchy can be identified and any population-, community-, or ecosystem-level structures that mute energy or material flow also stabilize systems dynamics. McCann uses this powerful general framework to discuss the effects of human impact on the stability and sustainability of ecological systems, and he demonstrates that there is clear empirical evidence that the structures supporting ecological systems have been dangerously eroded. Uniting the latest research on food webs with classical theories, this book will be a standard source in the understanding of natural food web functions.
