This extensively revised second edition provides a comprehensive overview of transient global amnesia (TGA). First, it deals with the history of TGA before moving on to clinical and diagnostic features and differential diagnosis. Subsequent chapters then discuss the investigation and predisposing and precipitating factors for TGA before attempting to synthesise these many strands in order to formulate ideas about the pathogenesis of TGA. Each of the chapters is devoted to a practical and structured overview of the particular topic, with use of case studies to illustrate the material. Based in part on the author¿s experience of TGA cases over 20 years and in part on a review of the published literature, this book will hopefully enlighten clinicians from a broad range of medical backgrounds on the clinical features, investigation, and pathogenesis of TGA.Transient Global Amnesia is aimed at any clinician with an interest in, or who encounters patients with, acute amnesia: neurologists, general physicians, old age psychiatrists, geriatricians, clinical neuropsychologists, and primary care physicians, as well as other professions allied to medicine with similar interests, such as members of memory assessment teams.

This book provides readers with an introduction to the materials and devices necessary for flexible sensors and electronics, followed by common techniques for fabrication of such devices and system-level integration. Key insights into fabrication and processing will guide readers through the tradeoff choices in designing such platforms. A comprehensive review of two specific, flexible bioelectronic platforms, related to smart bandages for wound monitoring and thread-based diagnostics for wearable health, will demonstrate practical application at the system level. The book also provides a unique electrical engineering perspective by reviewing circuit architectures for low noise signal conditioning of weak signals from sensors,, and for low power analog to digital converters for signal acquisition. To achieve energy autonomy, authors provide several example of CMOS energy harvesting front end circuits and voltage boosters. Beyond circuit architectures, the book also provides a review of the modern theory of sampling and recovery of sparse signals, also known as compressed sensing. They then highlight how these principles can be leveraged for design and implementation of efficient signal acquisition hardware and reliable processing of acquired data for flexible electronic platforms.

This textbook explores the mystery of human origins in the Arabian Peninsula, the lost Southern Crescent where humanity took its first steps toward civilization. Under Arabiäs surface of sand and stone lies a primordial realm of rolling grasslands, freshwater lakes, and river floodplains. This book aims to restore a critical missing chapter in the prehistory of our species that played out in this forgotten place of plenty.The author has carried out more than twenty years of fieldwork in Yemen and Oman, weaving his research together into an unorthodox tapestry of archaeology, environmental science, genetics, and Middle Eastern mythology. This volume peers beneath Arabiäs abandoned deserts, revealing a land that once served as a bridge between prehistoric worlds. This textbook is suitable for undergraduate and graduate students as well as all readers who are interested in learning about Arabian prehistory.

The textbook acquaints the reader with the architecture of receivers of analog and digital radio systems, helps to study the stages of designing a modern radio receiver and reveals the reasons and methods for its effective operation in networks for various purposes. Particular attention is paid to the methods of generating and processing signals in the receivers of digital systems with multiple access, which make it possible to provide data transfer rates close to the maximum possible (according to Shannon). As a textbook for students studying methods of optimal signal reception, the book will also be useful to specialists in the field of telecommunications involved in the development of radio receivers. The book shows how the development of theoretical, circuitry and integrated technologies led to the active introduction of algorithmic methods for signal processing changed both the design of receivers and the methods of forming the information flow in free space (MIMO, beamforming). The creation of a global 5G network based on heterogeneous networks puts forward new requirements for the architecture of receivers, which are determined by the requirements to achieve high data rates, low time delays or use in networks with coordinated multipoint transmission and reception (CoMP). To consolidate the knowledge gained, the book includes a complete set of materials for online classes, including questions and answers, a guide to solving problems for each chapter, and computer modeling units of receivers in the MicroCAP environment, based on preliminary calculations.

This book introduces the novel artificial intelligence technique of polymodels and applies it to the prediction of stock returns. The idea of polymodels is to describe a system by its sensitivities to an environment, and to monitor it, imitating what a natural brain does spontaneously. In practice this involves running a collection of non-linear univariate models. This very powerful standalone technique has several advantages over traditional multivariate regressions. With its easy to interpret results, this method provides an ideal preliminary step towards the traditional neural network approach. The first two chapters compare the technique with other regression alternatives and introduces an estimation method which regularizes a polynomial regression using cross-validation. The rest of the book applies these ideas to financial markets. Certain equity return components are predicted using polymodels in very different ways, and a genetic algorithm is described which combines these different predictions into a single portfolio, aiming to optimize the portfolio returns net of transaction costs. Addressed to investors at all levels of experience this book will also be of interest to both seasoned and non-seasoned statisticians.

The book provides a holistic review, presenting a multi-stakeholder, multi-disciplinary, international, and evidence-based approach to Information and Communications Technology (ICT) in migration. The book brings together different views and multifaceted responses to ICT-based migration management, examining their overlap, conflict, and synergies. The book is a major addition to the field, tackling important debates concerning humanitarianism and securitization in the reception of migrants, as well as exploring the role of digital technology in aiding migrant integration. The authors explore contentious areas such as the use of new technologies deployed on borders for migration management and border security under the umbrella of smart border solutions including drones, AI algorithms, and face recognition, which are widely criticized for ignoring the fundamental human rights of migrants. The research presented will depart from the euphoric appraisals that technology has made things easier for migrants and those who assist them, to critically examine the bane and boon, benefits and afflictions, highlighting the barriers, as well as the solutions, including several under-researched aspects of digital surveillance and the digital divide.This edited volume has been developed by the MIICT project, funded under the EU Horizon 2020 Action and Innovation programme, under grant agreement No 822380.Provides a positive approach to the integration of migrants, asylum seekers, and refugees using Information and Communications Technology (ICT) solutionsOffers a strategic approach to providing digital services for migrants at an EU, national and local levelBridges the gap between academia and front-line practitioners¿ work by providing theoretical, policy, ethical, and methodological recommendations
