This textbook details the architecture of a digital coherent optical system and describes its main digital signal processing (DSP) algorithms. The authors first show how the combination of advanced modulation techniques, DSP and coherent detection has led to significant gains in capacity and ease of operation. The authors follow the path of the information from its generation in the transmitter, to propagation through the fiber and processing by the DSP algorithms in the receiver. The work summarizes academic results and presents them in a didactic way to students and practitioners working on the area of optical communications. A full suite of classroom materials is included for easy integration into a curriculum, containing theoretic and simulation problems, and off-the-shelf Matlab/Octave functions.
This book constitutes the thoroughly refereed post-proceedings of the International Workshop on Mobile and Ubiquitous Information Access held in Udine, Italy in September 2003 during Mobile HCI 2003. Besides selected and revised workshop papers, several papers were specially invited to complete coverage of all relevant issues and extend the volume to a more representative survey of the state of the art in the area. The 21 articles in the book are organized in topical sections on - foundations: concepts, models, and paradigms; - interactions; - applications and experimental evaluations; - context and location.
Chaos: from simple models to complex systems aims to guide science and engineering students through chaos and nonlinear dynamics from classical examples to the most recent fields of research. The first part, intended for undergraduate and graduate students, is a gentle and self-contained introduction to the concepts and main tools for the characterization of deterministic chaotic systems, with emphasis to statistical approaches. The second part can be used as a reference by researchers as it focuses on more advanced topics including the characterization of chaos with tools of information theory and applications encompassing fluid and celestial mechanics, chemistry and biology.The book is novel in devoting attention to a few topics often overlooked in introductory textbooks and which are usually found only in advanced surveys such as: information and algorithmic complexity theory applied to chaos and generalization of Lyapunov exponents to account for spatiotemporal and non-infinitesimal perturbations.The selection of topics, numerous illustrations, exercises and proposals for computer experiments make the book ideal for both introductory and advanced courses.
Wound Healing, and the Myofibroblast: A Historical and Biological Perspective is the fruit of an interdisciplinary and international collaboration involving a historian of medicine (Dr. Zampieri), a physician (Dr. Coen), and a researcher (Prof. Gabbiani, world-renowned for his discovery of the myofibroblast). This book aims to draw a concise yet complete description of the conceptual evolution of wound healing, fibrosis and fibrosis-related pathologies from antiquity to present time, as well as commenting on the role of the myofibroblast and the key cell type essential for tissue repair and fibrosis (from its identification in 1971 throughout its 50-years-old history). By viewing this complex and century-long history from different perspectives, the book's authors aim to draw an exhaustive overview, with the hope of inspiring new and fruitful basic and clinical research. Interdisciplinary collaboration: complementary views from medical historian, a physician and a researcher A concise but detailed history of fibrosis, readers can discover the major scientific breakthroughs along this history Includes the pathophysiology of various fibrotic diseases Explores the role of myofibroblast in fibrosis development
This volume presents a collection of courses introducing the reader to the recent progress with attention being paid to laying solid grounds and developing various basic tools. It presents new results on phase transitions for gradient lattice models.
In genetically susceptible individuals, the ingestion of gluten and related proteins triggers an immune-mediated enteropathy known as celiac disease (CD). Recent epidemiological studies have shown that 1 in 100 people worldwide suffers from CD—a rate that establishes CD as one of the most common food intolerances. CD patients that eat wheat or related proteins, such as hordeins (barley) and secalins (rye), undergo an immunological response, localized in the small intestine, that destroys mature absorptive epithelial cells on the surface of the small intestine. Currently, the only way to treat CD is the total life-long avoidance of gluten ingestion. Therefore, people that have CD must follow a very strict diet and avoid products that contain wheat, rye, and barley. Avoiding cereals leads to a recovery from the disease and significant improvement of the intestinal mucosa and its absorptive functions. Celiac patients are not in the position to eat some of the most common foods, such as breads, pizzas, and biscuits, or to drink beer and whiskey. Because of the unique properties of gluten, producing good-quality gluten-free products is a big challenge for scientists. Science of Gluten-Free Foods and Beverages covers the work presented at the First International Conference on Gluten-Free Cereal Products and Beverages. The area of gluten-free foods and beverages is becoming more and more important, since the number of people with CD and gluten allergies is rising. In the United Kingdom, 10% of the population claims to have food allergies. This book will be extensively referenced. It is meant to give an overview of the work being carried out in the area of gluten-free science. Covers the work presented at the First International Conference on Gluten-Free Cereal Products and Beverages Provides an overview of the work being carried out in the area of gluten-free science Supports the production good-quality gluten-free products
As president of the Italian Liberal Party, Benedetto Croce was one of the most influential intellectuals involved in Italian public affairs after the fall of Mussolini. Placing Croce at the centre of historical events between 1943 and 1952, this book details his participation in Italy’s political life, and his major contributions to the rebirth of Italian democracy. Drawing on a great amount of primary material, including Croce’s political speeches, correspondences, diaries, and official documents from post-war Italy, this book illuminates the dynamic and progressive nature of Croce’s liberalism and the shortcomings of the old Liberal leaders. Providing a year-by-year account of Croce’s initiatives, author Fabio Fernando Rizi fills the gap in Croce’s biography, covering aspects of his public life often neglected, misinterpreted, or altogether ignored, and restores his standing among the founding fathers of modern Italy.
The novel aim of this book is to illustrate the MR imaging features of the fetal and the neonatal brain by matching prenatal and postnatal images for a wide range of neurological abnormalities. The focus is on both conventional and advanced MR imaging techniques, including high-resolution MR autopsy of the fetal brain. During the past ten years, neuroradiological evaluation of the neonatal and the prenatal brain has advanced tremendously. However, even though they are intrinsically related, these two critical stages in brain development are usually studied and presented separately. In order to have a sound understanding of neonatal brain diseases, detailed knowledge of prenatal brain pathology is immensely helpful; conversely, knowledge of neonatal brain disease is a prerequisite for understanding many fetal brain lesions. Written by experts in the field, Perinatal Neuroradiology will be of value for neuroradiologists and pediatric radiologists, as well as obstetricians and neonatologists.
