    A world that is as creative and complex as it is dangerous and disturbing. A world that is much closer than you think.The dark net is an underworld that stretches from popular social media sites to the most secretive corners of the encrypted web. It is a world that frequently appears in newspaper headlines, but one that is little understood, and rarely explored. The Dark Net is a revelatory examination of the internet today, and of its most innovative and dangerous subcultures: trolls and pornographers, drug dealers and hackers, political extremists and computer scientists, Bitcoin programmers and self-harmers, libertarians and vigilantes.Based on extensive first-hand experience, exclusive interviews and shocking documentary evidence, The Dark Net offers a startling glimpse of human nature under the conditions of freedom and anonymity, and shines a light on an enigmatic and ever-changing world.

    

    

    The most current information on the mechanisms, manifestations, and treatments of disease are clearly and concisely presented. Accessible writing, numerous illustrations in full-color, and complete and separate treatment of pediatric pathophysiology are the hallmarks of this popular and respected text. The new third edition features extensively revised and updated content and an enhanced art program.The book is divided into two parts. Part One presents the general principles of pathophysiology, including cell injury and repair; genetics; fluids and electrolytes, acids and bases; immunity, inflammation, and infection; stress; and cancer. Part Two is organized by body system, and for each system it covers normal anatomy and physiology, alterations of function in adults, and alterations of function in children.• Complete but concise coverage provides a thorough discussion of general pathophysiology and specific disease processes. • Outstanding full-color art program illustrates normal anatomy and physiology, disease processes, and clinical manifestations of disease. • Pediatric content is presented in 9 separate chapters to provide thorough coverage of how disease processes specifically affect children. • Health Alert boxes present brief discussions of new research, diagnostic studies, preventative care, treatments, or other developments related to health or specific diseases. • Quick Check questions appear at the end of major sections of text and are designed to promote critical thinking. Suggested answers to the questions are found on the CD companion included with the text. • Risk Factor boxes illustrate how certain risk factors are associated with specific diseases. • Did You Understand? chapter summaries provide students with a comprehensive review of the major concepts presented in each chapter. • Aging content is identified with a special icon within the adult chapters. • Algorithms are used throughout the text to illustrate normal and compensatory physiology and pathophysiology. • Key terms are boldface in text and listed with page numbers at the end of each chapter for easy reference and chapter review.• Approximately 250 new full-color drawings have been added. • An Introduction to Pathophysiology included in the front matter defines pathophysiology — and related terms such as etiology and epidemiology — and explains why it is important. • Extensive updates, based on the most current research, have been made throughout the book. • To reflect the latest developments, the Biology of Cancer chapter has been completely rewritten. • Several chapters, including Fluids and Electrolytes, Acids and Bases and Alterations of the Reproductive Systems have been extensively edited.

    It can be used as a course book for students who are first encountering systems analysis and design at any level.

    To understand it fully, we must look beneath the surface. The positive side is that technology is making machines smarter. However, the deeper view explained in this book shows that AI is also making a growing number of people cognitively and psychologically dependent on digital networks. Whether you are a social media fanatic, a diehard AI aficionado, or a paranoid sceptic, it is impossible to escape the ubiquitous impact of AI. Artificial Intelligence is the brains bringing together quantum computing, nanotechnology, medical technology, brain-machine interface, robotics, aerospace, 5G, Internet of Things, and more. It is amplifying human ingenuity and disrupting the foundations of healthcare, military, entertainment, education, marketing and manufacturing.Artificial Intelligence and The Future of Power argues that this AI-driven revolution will have an unequal impact on different segments of humanity. There will be new winners and losers, new haves and have-nots, resulting in an unprecedented concentration of wealth and power. After analyzing society’s vulnerabilities to the impending tsunami, the book raises troubling questions that provoke immediate debate: Is the world headed toward digital colonization by USA and China? Will depopulation become eventually unavoidable?Artificial Intelligence and The Future of Power is a wakeup call to action, compelling public intellectuals to be better informed and more engaged. It educates the social segments most at risk and wants them to demand a seat at the table where policies on Artificial Intelligence are being formulated.

    Building on the field of mathematical statistics, probabilistic robotics endows robots with a new level of robustness in real-world situations. This book introduces the reader to a wealth of techniques and algorithms in the field. All algorithms are based on a single overarching mathematical foundation. Each chapter provides example implementations in pseudo code, detailed mathematical derivations, discussions from a practitioner's perspective, and extensive lists of exercises and class projects. The book's Web site, www.probabilistic-robotics.org, has additional material. The book is relevant for anyone involved in robotic software development and scientific research. It will also be of interest to applied statisticians and engineers dealing with real-world sensor data.

    "Machine learning," the process of automating tasks once considered the domain of highly-trained analysts and mathematicians, is the key to efficiently extracting useful information from this sea of raw data. Machine Learning in Action is a unique book that blends the foundational theories of machine learning with the practical realities of building tools for everyday data analysis. In it, the author uses the flexible Python programming language to show how to build programs that implement algorithms for data classification, forecasting, recommendations, and higher-level features like summarization and simplification.
