Liminal Lives: Imagining the Human at the Frontiers of Biomedicine
by Susan Merrill SquierEmbryo adoptions, stem cells capable of transforming into any cell in the human body, intra- and inter-species organ transplantation--these and other biomedical advances have unsettled ideas of what it means to be human, of when life begins and ends. In the first study to consider the cultural impact of the medical transformation of the entire human life span, Susan Merrill Squier argues that fiction--particularly science fiction--serves as a space where worries about ethically and socially charged scientific procedures are worked through. Indeed, she demonstrates that in many instances fiction has anticipated and paved the way for far-reaching biomedical changes. Squier uses the anthropological concept of liminality--the state of being on the threshold of change, no longer one thing yet not quite another--to explore how, from the early twentieth century forward, fiction and science together have altered not only the concept of the human being but the contours of human life. Drawing on archival materials of twentieth-century biology; little-known works of fiction and science fiction; and twentieth- and twenty-first century U. S. and U. K. government reports by the National Institutes of Health, the Parliamentary Advisory Group on the Ethics of Xenotransplantation, and the President's Council on Bioethics, she examines a number of biomedical changes as each was portrayed by scientists, social scientists, and authors of fiction and poetry. Among the scientific developments she considers are the cultured cell, the hybrid embryo, the engineered intrauterine fetus, the child treated with human growth hormone, the process of organ transplantation, and the elderly person rejuvenated by hormone replacement therapy or other artificial means. Squier shows that in the midst of new phenomena such as these, literature helps us imagine new ways of living. It allows us to reflect on the possibilities and perils of our liminal lives.

Limit States of Compressed Concrete Elements by Transverse Deformations
by Yuri Ribakov Iakov Iskhakov Ilya FrolovThe theoretical stress-strain model for compressed concrete (Iskhakov and Ribakov, 2018), is based on the structural phenomenon and requires no empirical coefficients. It includes such main parameters of concrete behavior as stresses and strains at the border between the elastic and non-elastic behavior, ultimate elastic strains and stresses and strains at the end of the post-peak region. Particular attention was focused on the descending branch of the stress-strain diagram and on concrete elastic and plastic potentials that are important for dynamic response of concrete element section and for concrete creep.The book presents experimental and numerical results confirming this model. It deals with experimental verification of theoretical models of cracking and failure scheme for cylindrical specimens. The importance of using transverse deformations for analysis of initiation and development of inelastic deformations under high loading rates is verified. The experimental and numerical results are in good agreement with the theoretical ones, which significantly reduces the number of empirical coefficients in compressed concrete elements design.
Limited Affordable Low-Volume Manufacturing: Summary of a Workshop
by Maureen Mellody"Limited Affordable Low-Volume Manufacturing" is the summary of a workshop convened by the National Materials and Manufacturing Board of the National Research Council in August 2013 to discuss affordable, low-volume manufacturing. The workshop focused on four critical issues relevant to manufacturing: low-volume manufacturing; use of commercial off-the-shelf equipment; short production runs; and commercial manufacturing services. The workshop discussion also considered variable-rate manufacturing and high-mix manufacturing, both aspects of low-volume manufacturing. This report examines the characteristics of low-volume manufacturing and considers future advances in limited affordable low-volume manufacturing in the United States.
Limited Boxed Set: Bill Gates, Big Pharma, and the Global War on Democracy and Public Health (Children’s Health Defense)
by Robert F. Kennedy Jr.#1 on AMAZON, and a NEW YORK TIMES, WALL STREET JOURNAL, USA TODAY and PUBLISHERS WEEKLY NATIONAL BESTSELLERPharma-funded mainstream media has convinced millions of Americans that Dr. Anthony Fauci is a hero. He is anything but.As director of the National Institute of Allergy and Infectious Diseases (NIAID), Dr. Anthony Fauci dispenses $6.1 billion in annual taxpayer-provided funding for scientific research, allowing him to dictate the subject, content, and outcome of scientific health research across the globe. Fauci uses the financial clout at his disposal to wield extraordinary influence over hospitals, universities, journals, and thousands of influential doctors and scientists—whose careers and institutions he has the power to ruin, advance, or reward. During more than a year of painstaking and meticulous research, Robert F. Kennedy Jr. unearthed a shocking story that obliterates media spin on Dr. Fauci . . . and that will alarm every American—Democrat or Republican—who cares about democracy, our Constitution, and the future of our children&’s health. The Real Anthony Fauci reveals how &“America&’s Doctor&” launched his career during the early AIDS crisis by partnering with pharmaceutical companies to sabotage safe and effective off-patent therapeutic treatments for AIDS. Fauci orchestrated fraudulent studies, and then pressured US Food and Drug Administration (FDA) regulators into approving a deadly chemotherapy treatment he had good reason to know was worthless against AIDS. Fauci repeatedly violated federal laws to allow his Pharma partners to use impoverished and dark-skinned children as lab rats in deadly experiments with toxic AIDS and cancer chemotherapies. In early 2000, Fauci shook hands with Bill Gates in the library of Gates&’ $147 million Seattle mansion, cementing a partnership that would aim to control an increasingly profitable $60 billion global vaccine enterprise with unlimited growth potential. Through funding leverage and carefully cultivated personal relationships with heads of state and leading media and social media institutions, the Pharma-Fauci-Gates alliance exercises dominion over global health policy. The Real Anthony Fauci details how Fauci, Gates, and their cohorts use their control of media outlets, scientific journals, key government and quasi-governmental agencies, global intelligence agencies, and influential scientists and physicians to flood the public with fearful propaganda about COVID-19 virulence and pathogenesis, and to muzzle debate and ruthlessly censor dissent.
Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Programs
by Aeronautics Space Engineering BoardDerelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

Limiting Global Warming to Well Below 2 °C: Energy System Modelling and Policy Development (Lecture Notes In Energy #64)
by George Giannakidis Maryse Labriet Kenneth Karlsson B. Ó GallachóirThis book presents the energy system roadmaps necessary to limit global temperature increase to below 2°C, in order to avoid the catastrophic impacts of climate change. It provides a unique perspective on and critical understanding of the feasibility of a well-below-2°C world by exploring energy system pathways, technology innovations, behaviour change and the macro-economic impacts of achieving carbon neutrality by mid-century. The transformative changes in the energy transition are explored using energy systems models and scenario analyses that are applied to various cities, countries and at a global scale to offer scientific evidence to underpin complex policy decisions relating to climate change mitigation and interrelated issues like energy security and the energy–water nexus. It includes several chapters directly related to the Nationally Determined Contributions proposed in the context of the recent Paris Agreement on Climate Change. In summary, the book collates a range of concrete analyses at different scales from around the globe, revisiting the roles of countries, cities and local communities in pathways to significantly reduce greenhouse gas emissions and make a well-below-2°C world a reality. A valuable source of information for energy modellers in both the industry and public sectors, it provides a critical understanding of both the feasibility of roadmaps to achieve a well-below-2°C world, and the diversity and wide applications of energy systems models. Encompassing behaviour changes; technology innovations; macro-economic impacts; and other environmental challenges, such as water, it is also of interest to energy economists and engineers, as well as economic modellers working in the field of climate change mitigation.
Limiting Modes of Aircraft Flight: Methods, Algorithms and Results (Springer Aerospace Technology)
by Dmitry Alexandrovich Zatuchny Vadim Vadimovich Vorobyov Alexander Nikolaevich AkimovThis book describes in detail a method of direct optimization, which makes it possible to choose the best trajectory of an aircraft in conditions of its limited resource. This can happen in the event of an emergency on board, associated with both a possible equipment failure and external influences, for example, when lightning strikes an aircraft or collides with a moving object. The highlight of this book is the fact that the results presented in it can be applied universally to the choice of the flight path of large and small aircraft, as well as helicopter technology. In addition, they take into account various conditions of aircraft flight, including a possible accident. The methods and algorithms presented here can be used as the basis for the creation of automatic collision avoidance systems, as well as the choice of the best aircraft trajectory for flights in different regions and in different conditions.

Limits of AI - theoretical, practical, ethical (Technik im Fokus)
by Klaus Mainzer Reinhard KahleArtificial intelligence is a key technology with great expectations in science, industry, and everyday life. This book discusses both the perspectives and the limitations of this technology. This concerns the practical, theoretical, and conceptual challenges that AI has to face. In an early phase of symbolic AI, AI focused on formal programs (e.g., expert systems), in which rule-based knowledge was processed with the help of symbolic logic. Today, AI is dominated by statistics-based machine learning methods and Big Data. While this sub-symbolic AI is extremely successful (e.g., chatbots like ChatGPT), it is often not transparent. The book argues for explainable and reliable AI, in which the logical and mathematical foundations of AI-algorithms become understandable and verifiable.
Limits of Life: Reflections on Life, Death, and the Body in the Age of Technoscience
by Martin Eggen Mogseth & Fartein Hauan NilsenNew technologies and scientific imagination rearrange the boundary that we identify as the beginning and end of life. New techno-social constellations, such as the ever-increasing presence of digital avatars and genetic screenings, implore us to reconsider and transcend the existing definitions of life and death. Through a multidisciplinary approach, this volume explores how the limitations and perceived finality of life and death are reconstituted through engagements with modern technology.
Limits of Stability and Stabilization of Time-Delay Systems
by Jie Chen Jing Zhu Tian Qi Dan MaThis authored monograph presents a study on fundamental limits and robustness of stability and stabilization of time-delay systems, with an emphasis on time-varying delay, robust stabilization, and newly emerged areas such as networked control and multi-agent systems. The authors systematically develop an operator-theoretic approach that departs from both the traditional algebraic approach and the currently pervasive LMI solution methods. This approach is built on the classical small-gain theorem, which enables the author to draw upon powerful tools and techniques from robust control theory. The book contains motivating examples and presents mathematical key facts that are required in the subsequent sections. The target audience primarily comprises researchers and professionals in the field of control theory, but the book may also be beneficial for graduate students alike.

Limnology, Climatology and Paleoclimatology of the East African Lakes
by Eric O. Odada Thomas C. JohnsonThe large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Line Groups in Physics
by Milan Damnjanovic Ivanka MilosevicThis volume gives a detailed and up-to-date overview of the line groups, the groups that describe the symmetry of quasi-one dimensional crystals. Nanotubes, nanowires, nanosprings, nanorods, and polymers are examples remarkable enough to have kept nanoscience as a leading field within material science and solid state physics for more than fifteen years now. The authors present the mathematical foundations, including classifications of the line groups, quasi one-dimensional crystals and quantum numbers, together with important applications. Extensive illustrations related to the physics of nanotubes make the book essential reading in this field above all. The book clearly demonstrates how symmetry is a most profound property of nature and contains valuable results that are published here for the first time.

Linear Algebra Based Controllers: Design and Applications
by Gustavo Scaglia Mario Emanuel Serrano Pedro AlbertosThis book summarizes the application of linear algebra-based controllers (LABC) for trajectory tracking for practitioners and students across a range of engineering disciplines. It clarifies the necessary steps to apply this straight-forward technique to a non-linear multivariable system, dealing with continuous or discrete time models, and outlines the steps to implement such controllers. In this book, the authors present an approach of the trajectory tracking problem in systems with dead time and in the presence of additive uncertainties and environmental disturbances. Examples of applications of LABC to systems in real operating conditions (mobile robots, marine vessels, quadrotor and pvtol aircraft, chemical reactors and First Order Plus Dead Time systems) illustrate the controller design in such a way that the reader attains an understanding of LABC.

The authors also focuses on design guidelines of the inductor's geometrical characteristics for power applications and covers their measurement and characterization. Additionally, a model is proposed which would facilitate designs in terms of transistor sizing, required inductor quality factors or minimum supply voltage. The model considers limitations that CMOS processes can impose on implementation. The book also provides different techniques and architectures that allow for optimization.
Linear CMOS RF Power Amplifiers for Wireless Applications
by Paulo Augusto Dal Fabbro Maher KayalThe RF power amplifier is a key component in a wireless transceiver and is considered by many as the design bottleneck in the transmitting chain. Linear CMOS RF Power Amplifiers for Wireless Applications addresses two fundamental aspects in RF power amplifier design for integration in CMOS technologies at 2.4, 3.7 and 5.2 GHz: efficiency enhancement and frequency agility. The well-known linearity-efficiency trade-off is circumvented by employing an efficiency-enhancement technique called the dynamic supply RF power amplifier. The design of this system is described with great detail and compared with other efficiency enhancement techniques. The frequency agility is achieved with a novel impedance matching network based on coupled inductors. The design of a dual-band RF power amplifier is shown, with a careful analysis of the tunable matching network and its interaction with the rest of the circuit. The considerations and conclusions drawn throughout this book are based on simulation as well as measurement results from the integrated circuit prototypes carefully built and respecting best practices in RF design.
