Multiaccess, Reservations & Queues
Reservation procedures constitute the core of many popular data transmission protocols. They consist of two steps: A request phase in which a station reserves the communication channel and a transmission phase in which the actual data transmission takes place. Such procedures are often applied in communication networks that are characterised by a shared communication channel with large round-trip times.In this book, we propose queuing models for situations that require a reservation procedure and validate their applicability in the context of cable networks.
MRI of the Heart and Vessels
In recent years magnetic resonance imaging (MRI) has enriched the technological potential available for the characterization of cardiovascular pathologies, adding substantial advantages to other non-invasive techniques. This technique, which is intrinsically digital and has reduced operator dependency, allows the performance of image analysis in a quantitative and reproducible manner. In virtue of its added diagnostic value and inherent refinements that allow construction of two- and three-dimensional images, MRI is gaining a primary role in the histopathological and physiopathological understanding of a large number of pathologies concerning the heart and vessels. This text is addressed both to MRI operators seeking specific technical information and to clinicians who wish to have a better understanding of the diagnostic and management advantages that MRI can offer.

Mono-Cycle Photonics and Optical Scanning Tunneling Microscopy : Route to Femtosecond Ångstrom Technology
"Mono-Cycle Photonics and Optical Scanning Tunneling Microscopy" deals with both the ultrashort laser-pulse technology in the few- to mono-cycle region and the laser-surface-controlled scanning-tunneling microscopy (STM) extending into the spatiotemporal extreme technology. The former covers the theory of nonlinear pulse propagation beyond the slowly-varing-envelope approximation, the generation and active chirp compensation of ultrabroadband optical pulses, the amplitude and phase characterization of few- to mono-cycle pulses, and the feedback field control for the mono-cycle-like pulse generation. In addition, the wavelength-multiplex shaping of ultrabroadband pulse is described. The latter covers the CW-laser-excitation STM, the femtosecond-time-resolved STM and atomic-level surface phenomena controlled by femtosecond pulses.

Molecular Markers of Brain Tumor Cells : Implications for Diagnosis, Prognosis and Anti-Neoplastic Biological Therapy
Childhood brain tumors are a diverse group of diseases characterized by the abnormal growth of tissue contained within the skull. Other than leukemia and lymphoma, brain tumors are the most common type of neoplasms that occur in children. The leading cause of death from childhood neoplasms among persons up to 19 years is brain tumors. As such, this book is a review of the most recent molecular biological research concerning brain tumors with references and comparisons to a variety of neoplastic disorders. The book then uses this information to foreshadow the direction that future anti-neoplastic therapies will take. Because of the wide spectrum of the objectives of the book, any individual involved in cancer research will greatly benefit from the work. Histopathologists, neuropathologists, clinical and research oncologists, and medical students will find this book to be an invaluable resource as a reference guide. Patients and their families will also find the book useful as it offers a comprehensive update on new, non-classical therapeutic modality options and contains a detailed description and analysis of brain tumors. Such an endeavor has yet to be undertaken by any other book and may prove to be the most comprehensive book on brain tumors thus far.
Molecular Imaging II
The aim of this textbook of molecular imaging is to provide an up to date review of this rapidly growing field and to discuss basic methodological aspects necessary for the interpretation of experimental and clinical results. Emphasis is placed on the interplay of imaging technology and probe development, since the physical properties of the imaging approach need to be closely linked with the biologic application of the probe (i.e. nanoparticles and microbubbles). Various chemical strategies are discussed and related to the biologic applications. Reporter-gene imaging is beeing addressed not only in experimental protocols, but also first clinical applications are discussed. Finally, strategies of imaging to characterize apoptosis and angiogenesis are described and discussed in the context of possible clinical translation.

Molecular Biology in Plant Pathogenesis and Disease Management : Disease Management ; Vol.3
Exclusion and eradication of plant pathogens by rapid and precise detection and identification of microbial pathogens in symptomatic and asymptomatic plants and planting materials by employing molecular methods has been practiced extensively by quarantines and certification programs with a decisive advantage. Identification of sources of resistance genes, cloning and characterization of desired resistance genes and incorporation of resistance gene(s) into cultivars and transformation of plants with selected gene(s) have been successfully performed by applying appropriate molecular techniques. Induction of resistance in susceptible cultivars by using biotic and abiotic inducers of resistance is a practical proposition for several crops whose resistance levels could not be improved by breeding or transformation procedures. The risks of emergence of pathogen strains less sensitive or resistant to chemicals have been reduced appreciably by rapid identification of resistant strains and monitoring the occurrence of such strains in different geographical locations.

Modern treatments for chronic blood diseases
Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloida osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). Thalassemias are inherited blood disorders characterized by decreased hemoglobin production Symptoms depend on the type and can vary from none to severe. Often there is mild to severe anemia (low red blood cells or hemoglobin). Anemia can result in feeling tired and pale skin. There may also be bone problems, an enlarged spleen, yellowish skin, and dark urine. Slow growth may occur in children.

Modern Differential Geometry in Gauge Theories : Maxwell Fields ; Vol. I
Differential geometry, in the classical sense, is developed through the theory of smooth manifolds. Modern differential geometry from the author’s perspective is used in this work to describe physical theories of a geometric character without using any notion of calculus (smoothness). Instead, an axiomatic treatment of differential geometry is presented via sheaf theory (geometry) and sheaf cohomology (analysis). Using vector sheaves, in place of bundles, based on arbitrary topological spaces, this unique approach in general furthers new perspectives and calculations that generate unexpected potential applications .Volume 1, the focus is on Maxwell fields. All the basic concepts of this mathematical approach are formulated and used thereafter to describe elementary particles, electromagnetism, and geometric prequantization. Maxwell fields are fully examined and classified in the language of sheaf theory and sheaf cohomology.
