28 Barbary Lane: "Tales of the City" Books 1-3

by Armistead Maupin

Armistead Maupin's uproarious and moving Tales of the City novels--the first three of which are collected in this omnibus volume--have earned a unique niche in American literature and are considered indelible documents of cultural change from the seventies through the first two decades of the new millennium."These novels are as difficult to put down as a dish of pistachios. The reader starts playing the old childhood game of 'Just one more chapter and I'll turn out the lights,' only to look up and discover it's after midnight."--Los Angeles Times Book Review Originally serialized in the San Francisco Chronicle, Armistead Maupin's Tales of the City (1978), More Tales of the City (1980), and Further Tales of the City (1982) afforded a mainstream audience of millions its first exposure to straight and gay characters experiencing on equal terms the follies of urban life. Among the cast of this groundbreaking saga are the lovelorn residents of 28 Barbary Lane: the bewildered but aspiring Mary Ann Singleton, the libidinous Brian Hawkins; Mona Ramsey, still in a sixties trance, Michael "Mouse" Tolliver, forever in bright-eyed pursuit of Mr. Right; and their marijuana-growing landlady, the indefatigable Mrs. Madrigal. Hurdling barriers both social and sexual, Maupin leads them through heartbreak and triumph, through nail-biting terrors and gleeful coincidences. The result is a glittering and addictive comedy of manners that continues to beguile new generations of readers.

The 30-Day Sobriety Solution

by Jack Canfield Dave Andrews

From the bestselling co-author of Chicken Soup for the Soul comes a revolutionary programme to help you cut back or quit drinking entirely - on your own and in the privacy of your own home. Existing established published resources have utterly failed to help most alcoholics. Only a tiny percentage of those with alcohol abuse issues ever receive any sort of treatment, including Alcoholics Anonymous, which provides a dated programme of recovery that many find difficult to accept or practical to implement. There has also been no dramatic decline in alcoholism over time, suggesting that we are desperately in need of a fresh approach. The 30-Day Sobriety Solutionoffers the answer to anyone who feels their drinking has become unmanageable. Inspired by Canfield's work in self-esteem and success training and developed into a programme by Dave Andrews, it integrates positive psychology, neurolinguistic programming, cognitive therapy, meditation, positive self-talk and the correction of negative self-perceptions, amongst numerous other techniques. At the core of this programme are the two concepts of a no alcohol '30-Day Reboot', with the option of a non-abstinence track after the first 30 days. This is a model of sobriety that you can achieve in the privacy of your own home in only a few minutes a day.

The 34th Rule (Star Trek: Deep Space Nine #23)

by David R. George III Armin Shimerman

For once, business is going well for Quark, not that anyone on Deep Space Nine truly appreciates his genius for finding profit in the most unlikely of circumstances. Quark is even looking forward to making the deal of a lifetime -- when he suddenly finds himself stuck right in the middle of a major dispute between Bajor and the Ferengi Alliance. It seems that the Grand Nagus is refusing to sell one of the lost Orbs of the Prophets to the Bajoran government, which has responded by banning all Ferengi activity in Bajoran space. With diplomatic relations between the two cultures rapidly breaking down, Quark loses his bar first, then his freedom. But even penniless, he still has his cunning and his lobes, and those alone may be all he needs to come out on top -- and prevent an interstellar war!

365 Days

by Ronald J. Glasser

The classic and heartrending account of the Vietnam War as seen through the eyes of an army doctorIn 1968, as a serviceman in the Vietnam War, Dr. Ronald Glasser was sent to Japan to work at the US Army hospital at Camp Zama. It was the only general army hospital in Japan, and though Glasser was initially charged with tending to the children of officers and government officials, he was soon caught up in the waves of casualties that poured in from every Vietnam front. Thousands of soldiers arrived each month, demanding the help of every physician within reach. In 365 Days, Glasser reveals a candid and shocking account of that harrowing experience. He gives voice to seventeen of his patients, wounded men counting down the days until they return home. Their stories bring to life a world of incredible bravery and suffering, one where "the young are suddenly left alone to take care of the young." An instant classic of war literature, 365 Days is a remarkable, ground-level account of Vietnam's human toll.

3D Biometrics: Systems and Applications

by Guangming Lu David Zhang

Automatic personal authentication using biometric information is becoming more essential in applications of public security, access control, forensics, banking, etc. Many kinds of biometric authentication techniques have been developed based on different biometric characteristics. However, most of the physical biometric recognition techniques are based on two dimensional (2D) images, despite the fact that human characteristics are three dimensional (3D) surfaces. Recently, 3D techniques have been applied to biometric applications such as 3D face, 3D palmprint, 3D fingerprint, and 3D ear recognition. This book introduces four typical 3D imaging methods, and presents some case studies in the field of 3D biometrics. This book also includes many efficient 3D feature extraction, matching, and fusion algorithms. These 3D imaging methods and their applications are given as follows: - Single view imaging with line structured-light: 3D ear identification - Single view imaging with multi-line structured-light: 3D palmprint authentication - Single view imaging using only 3D camera: 3D hand verification - Multi-view imaging: 3D fingerprint recognition 3D Biometrics: Systems and Applications is a comprehensive introduction to both theoretical issues and practical implementation in 3D biometric authentication. It will serve as a textbook or as a useful reference for graduate students and researchers in the fields of computer science, electrical engineering, systems science, and information technology. Researchers and practitioners in industry and R&D laboratories working on security system design, biometrics, immigration, law enforcement, control, and pattern recognition will also find much of interest in this book.

3D Future Internet Media

by Tasos Dagiuklas Ahmet Kondoz

This book describes recent innovations in 3D media and technologies, with coverage of 3D media capturing, processing, encoding, and adaptation, networking aspects for 3D Media, and quality of user experience (QoE). The main contributions are based on the results of the FP7 European Projects ROMEO, which focus on new methods for the compression and delivery of 3D multi-view video and spatial audio, as well as the optimization of networking and compression jointly across the Future Internet (www. ict-romeo. eu). The delivery of 3D media to individual users remains a highly challenging problem due to the large amount of data involved, diverse network characteristics and user terminal requirements, as well as the user's context such as their preferences and location. As the number of visual views increases, current systems will struggle to meet the demanding requirements in terms of delivery of constant video quality to both fixed and mobile users. ROMEO will design and develop hybrid-networking solutions that combine the DVB-T2 and DVB-NGH broadcast access network technologies together with a QoE aware Peer-to-Peer (P2P) distribution system that operates over wired and wireless links. Live streaming 3D media needs to be received by collaborating users at the same time or with imperceptible delay to enable them to watch together while exchanging comments as if they were all in the same location. The volume provides state-of-the-art information on 3D multi-view video, spatial audio networking protocols for 3D media, P2P 3D media streaming, and 3D Media delivery across heterogeneous wireless networks among other topics. Graduate students and professionals in electrical engineering and computer science with an interest in 3D Future Internet Media will find this volume to be essential reading.

The diverse challenges of 3D Geoinformation Science concern new approaches and the development of standards for above- and under-ground 3D modeling, efficient 3D data management, visualization and analysis. Finally, the integration of different 3D approaches and data models is seen as one of the most important challenges to be solved.

3D Imaging in Endodontics

by Bradford R. Johnson Mohamed Fayad

This book is designed to provide the reader with a full understanding of the role of cone beam computed tomography (CBCT) in helping to solve many of the most challenging problems in endodontics. It will shorten the learning curve in application of this exciting imaging technique in a variety of contexts: difficult diagnostic cases, treatment planning, evaluation of internal tooth anatomy prior to root canal therapy, nonsurgical and surgical treatments, early detection and treatment of resorptive defects, and outcomes assessment. The ability to obtain an accurate 3D representation of a tooth and the surrounding structures by means of noninvasive CBCT imaging is changing the approach to clinical decision making in endodontics. Clinicians long accustomed to working in very small, three-dimensional spaces are no longer constrained by the limitations of two-dimensional imaging. The challenges of mastering the new technology can, however, be daunting. The detailed guidance contained in this book will help endodontists to take full advantage of the important benefits offered by CBCT.

3D Imaging Technologies in Atherosclerosis

by Jasjit S. Suri Luca Saba Rikin Trivedi

Atherosclerosis represents the leading cause of mortality and morbidity in the world. Two of the most common, severe, diseases that may occur, acute myocardial infarction and stroke, have their pathogenesis in the atherosclerosis that may affect the coronary arteries as well as the carotid/intra-cranial vessels. Therefore, in the past there was an extensive research in identifying pre-clinical atherosclerotic diseases in order to plan the correct therapeutical approach before the pathological events occur. In the last 20 years imaging techniques and in particular Computed Tomography and Magnetic Resonance had a tremendous improvement in their potential. In the field of the Computed Tomography the introduction of the multi-detector-row technology and more recently the use of dual energy and multi-spectral imaging provides an exquisite level of anatomic detail. The MR thanks to the use of strength magnetic field and extremely advanced sequences can image human vessels very quickly while offering an outstanding contrast resolution.

3D Multiscale Physiological Human

by Hon Fai Choi Osman Ratib Nadia Magnenat-Thalmann

3D Multiscale Physiological Human aims to promote scientific exchange by bringing together overviews and examples of recent scientific and technological advancements across a wide range of research disciplines. As a result, the variety in methodologies and knowledge paradigms are contrasted, revealing potential gaps and opportunities for integration. Chapters have been contributed by selected authors in the relevant domains of tissue engineering, medical image acquisition and processing, visualization, modeling, computer aided diagnosis and knowledge management. The multi-scale and multi-disciplinary research aspects of articulations in humans are highlighted, with a particular emphasis on medical diagnosis and treatment of musculoskeletal diseases and related disorders. The need for multi-scale modalities and multi-disciplinary research is an emerging paradigm in the search for a better biological and medical understanding of the human musculoskeletal system. This is particularly motivated by the increasing socio-economic burden of disability and musculoskeletal diseases, especially in the increasing population of elderly people. Human movement is generated through a complex web of interactions between embedded physiological systems on different spatiotemporal scales, ranging from the molecular to the organ level. Much research is dedicated to the understanding of each of these systems, using methods and modalities tailored for each scale. Nevertheless, combining knowledge from different perspectives opens new venues of scientific thinking and stimulates innovation. Integration of this mosaic of multifaceted data across multiple scales and modalities requires further exploration of methods in simulations and visualization to obtain a comprehensive synthesis. However, this integrative approach cannot be achieved without a broad appreciation for the multiple research disciplines involved.

The 4400: Wet Work

by Kevin Dilmore Dayton Ward

1992: For nearly a decade, the international assassin known only as "the Wraith" has eluded authorities. Political leaders, powerful heads of business, terrorists known and suspected have numbered among the many victims until -- without explanation -- the Wraith disappears.... 2005: Tom Baldwin and Diana Skouris are investigating Jordan Collier's murder, but they're pulled off the case. Washington believes the Wraith -- a onetime freelance agent for the U.S. government -- is active again. A high-ranking CIA officer, who oversaw the rogue operator's activities, is killed. Evidence at the scene points to the Wraith and that this highly efficient killer is now a 4400. The NTAC agents only have thirteen-year-old leads to follow an assassin who was never caught. Suddenly, the Wraith kills another returnee. Why? What does this mean? Can the mounting fears of the 4400 be right? Or is this just one returnee who has gone off the track. Baldwin and Skouris need to know -- but will they find out before the Wraith completes this deadly covert objective?

4D Modeling and Estimation of Respiratory Motion for Radiation Therapy

by Jan Ehrhardt Cristian Lorenz

Respiratory motion causes an important uncertainty in radiotherapy planning of the thorax and upper abdomen. The main objective of radiation therapy is to eradicate or shrink tumor cells without damaging the surrounding tissue by delivering a high radiation dose to the tumor region and a dose as low as possible to healthy organ tissues. Meeting this demand remains a challenge especially in case of lung tumors due to breathing-induced tumor and organ motion where motion amplitudes can measure up to several centimeters. Therefore, modeling of respiratory motion has become increasingly important in radiation therapy. With 4D imaging techniques spatiotemporal image sequences can be acquired to investigate dynamic processes in the patient's body. Furthermore, image registration enables the estimation of the breathing-induced motion and the description of the temporal change in position and shape of the structures of interest by establishing the correspondence between images acquired at different phases of the breathing cycle. In radiation therapy these motion estimations are used to define accurate treatment margins, e.g. to calculate dose distributions and to develop prediction models for gated or robotic radiotherapy. In this book, the increasing role of image registration and motion estimation algorithms for the interpretation of complex 4D medical image sequences is illustrated. Different 4D CT image acquisition techniques and conceptually different motion estimation algorithms are presented. The clinical relevance is demonstrated by means of example applications which are related to the radiation therapy of thoracic and abdominal tumors. The state of the art and perspectives are shown by an insight into the current field of research. The book is addressed to biomedical engineers, medical physicists, researchers and physicians working in the fields of medical image analysis, radiology and radiation therapy.
