Book Description
Detailed descriptions of detection, direction-finding, and signal-estimation methods, using consistent formalisms and notation, emphasizing HF antenna array sensing applications. Adaptive antenna array technology encompasses many powerful interference suppression approaches that exploit spatial differences among signals reaching a radio receiver system. Today, worldwide propagation phenomenology occurring in the High Frequency (HF) radio regime has made such interference common. In this book, Jay Sklar, a longtime researcher at MIT Lincoln Laboratory, presents detailed descriptions of detection, direction-finding, and signal-estimation methods applicable at HF, using consistent formalisms and notation. Modern electronic system technology has made many of these techniques affordable and practical; the goal of the book is to offer practicing engineers a comprehensive and self-contained reference that will encourage more widespread application of these approaches. The book is based on the author's thirty years of managing MIT Lincoln Laboratory work on the application of adaptive antenna array technologies to the sensing of HF communication signals. After an overview of HF propagation phenomenology, communication signal formats, and HF receiver architectural approaches, Sklar describes the HF propagation environment in more detail; introduces important modulation approaches and signaling protocols used at HF; discusses HF receiver system architectural features; and addresses signal processor architecture and its implementation. He then presents the technical foundation for the book: the vector model for a signal received at an adaptive array antenna. He follows this with discussions of actual signal processing techniques for detection and direction finding, including specific direction-finding algorithms; geolocation techniques; and signal estimation.

Book Description
". . . every critical examination of HF therapy in the United States has documented that we are not using all the weapons in our arsenal. We know what works, yet we are not systematically applying these proven therapies." —from the Introduction If you are interested in a better way to treat heart failure, this book is for you. Dr. Michael McIvor – who has taught thousands of healthcare professionals how to effectively care for patients with chronic HF through CME symposia – takes a logical, step-by-step approach to setting up and operating the kind of program that reduces hospital admissions and improves patient care. Establishing a Heart Failure Program: The Essential Guide answers the different questions posed by physicians, nurse practitioners, nurses, and hospital administrators, all of whom need to work as a team to achieve success. The three major sections of the book address: Taking the first steps toward building your heart failure program - developing a business plan, choosing your model of care, and making accurate financial projections Assembling the pieces of your program – managers, front line staff, and the physical facility Day-to-day operations A companion website presents forms you can download and use in your own heart failure center. Drawing from experience, Dr. McIvor helps you avoid common problems by identifying potential problems and sharing advice that has proven effective to your colleagues. He gives you the essential tools – unavailable elsewhere – to set up and maintain a heart failure program that achieves superior clinical outcomes.

Book Description
Many people have experienced such unusual phenomena as dreams that later seem to correspond with unforeseeable events, thinking of a long-lost friend just before he or she unexpectedly calls, or the ability to "feel" the presence of deceased loved ones. What many do not realize is that these types of experiences have been researched for more than a century by eminent scientists, including Nobel laureates. Most of these researchers have concluded that some of these phenomena do occur, although we are far from explaining them to everyone's satisfaction. This book is the first in almost 40 years to provide a comprehensive scientific overview of research in the field of parapsychology, explaining what we know and don't know about so-called psi phenomena, such as "telepathy," "precognition" or "psychokinesis." Contributors evaluate the evidence for these phenomena, accounting for factors such as selective memory, wish fulfillment and incorrect methods or analyses, in some cases offering psychological, physical and biological theories. Instructors considering this book for use in a course may request an examination copy here.

Book Description
The role of intelligence in US government operations has changed dramatically and is now more critical than ever to domestic security and foreign policy. This authoritative and highly researched book written by Jeffrey T. Richelson provides a detailed overview of America's vast intelligence empire, from its organizations and operations to its management structure. Drawing from a multitude of sources, including hundreds of official documents, The US Intelligence Community allows students to understand the full scope of intelligence organizations and activities, and gives valuable support to policymakers and military operations. The seventh edition has been fully revised to include a new chapter on the major issues confronting the intelligence community, including secrecy and leaks, domestic spying, and congressional oversight, as well as revamped chapters on signals intelligence and cyber collection, geospatial intelligence, and open sources. The inclusion of more maps, tables and photos, as well as electronic briefing books on the book's Web site, makes The US Intelligence Community an even more valuable and engaging resource for students.

Book Description
Angiotensin: From the Kidney to Coronavirus, a new volume in the Molecular Mediators in Health and Disease series, presents the communication role of the hormone in both health and disease states. Beyond the most common conditions, the book also explores the role of Angiotensin in infectious diseases, like COVID-19. Sections provide background to its discovery and role in homeostasis, focus on molecular biology aspects, including genetics and measurements of its associated proteins, describe the specific actions of angiotensin in normal physiology with different organ systems, survey different classes of drugs that act on the Renin-angiotensin-aldosterone system, cover non-angiotensin II peptides, and more. The final part of the book is dedicated to angiotensin's role in disease states, making this the ideal reference for researchers in life sciences interested in understanding the physiological role of Angiotensin in a complete fashion. Research physicians will also benefit from the book's complete coverage of organ systems and diseases where Angiotensin plays a key role. - Covers the traditional disorders related to Angiotensin and new findings like its role in infectious diseases like COVID-19 - Offers an overview of all important aspects of angiotensin, from discovery to clinical application, from physical and chemical properties to the physiological/cellular interaction - Expands on the role of angiotensin beyond the individual system the researcher is focusing, providing a comprehensive coverage of the additional effects at cell, tissue, organ, and system levels
