The theory of automorphic forms is formulated in terms of reductive algebraic groups. This is sometimes a serious obstacle for mathematicians whose background does not include Lie groups and Lie algebras. The monograph is by no means intended to exclude such mathematicians, even though the theory of reductive groups was an informal prerequisite for the Summer School. Some modest familiarity with the language of algebraic groups is often sufficient, at least to get started. For this reason, we have generally resisted the temptation to work with specific matrix groups. The short article of Murnaghan contains a summary of some of the basic properties of reductive algebraic groups that are used elsewhere in the monograph. |

The importance of specific antibodies for the clearance of and long-term resistance to many infectious pathogens has long been appreciated. Moreover, the role in these processes of the different antibody heavy chain isotypes, each tailored to induce diverse effector pathways such as those mediated by complement and Fc receptors and to promote antibody localization in distinct regions of the body, is well established. Insights into the molecular mechanism of isotype class switching showed that during an immune response B cells could change the heavy chain of the antibody they produced, without influencing the structure and specificity of the antigen-binding variable regions of this antibody (Honjo 1983). More recently, the germinal center pathway of B cell development was elucidated, in which antibody variable regions undergo extensive structural alteration via hypermutation followed by stringent phenotypic selection (Berek 1992; Kelsoe 1995). Emerging from this pathway are memory B cells and long-lived antibody-forming cells that express antigen receptors and secrete antibodies, respectively, with increased affinity and specificity for the foreign antigen. |

In Secrets of Cold War Technology, Gerry Vassilatos reveals that "Death Ray" technology has been secretly researched and developed since the turn of the century. Included are chapters on H. C. Vion, the developer of auroral energy receivers; Dr. Selim Lemstrom's pre-Tesla experiments; the early beam weapons of Grindell-Mathews; John Hettenger and his early beam power systems. |

The Deep Space Communications and Navigation Systems Center of Excellence (DESCANSO) was established in 1998 by the National Aeronautics and Space Administration (NASA) at the California Institute of Technology’s Jet Propulsion Laboratory (JPL). DESCANSO is chartered to harness and promote excellence and innovation to meet the communications and navigation needs of future deep-space exploration. DESCANSO’s vision is to achieve continuous communications and precise navigation—any time, anywhere. In support of that vision, DESCANSO aims to seek out and advocate new concepts, systems, and technologies; foster key technical talents; and sponsor seminars, workshops, and symposia to facilitate interaction and idea exchange. The Deep Space Communications and Navigation Series, authored by scientists and engineers with many years of experience in their respective fields, lays a foundation for innovation by communicating state-of-the-art knowledge in key technologies. The series also captures fundamental principles and practices developed during decades of deep-space exploration at JPL. |

Tetanus is a frequently fatal disease caused by the bacterium Clostridium tetani. The disease is characterized by intense, painful muscle contractions, sometimes strong enough to break even the strongest bones in the body. Reflecting the symptoms of the disease, the word tetanus is derived from the Greek term tetanos, meaning “to contract.” Historically, tetanus had a high mortality rate. With the limited medical treatment available in the 1940s in the United States, for example, the death rate for tetanus was estimated to be over 90 percent.2 Even with intensive medical treatment, the death rate is still 5 to 10 percent. |

Did you know that both electricity and light move in waves, like water does? What does electricity have to do with magnets? From Benjamin Franklin and Charles de Coulomb to Georg Ohm and James Joule, readers will be introduced to the basic principles of light, electricity, and magnetism in an illuminating way. Secrets of the Universe uses the basic principles of the scientific laws of physics to explain how and why things happen the way they do. Experiments and diagrams printed in special metallic inks illustrate each law and make the complex ideas simple and appealing. Also includes timelines of great discoveries and short bios of extraordinary scientists. |

Since its introduction by Tswett in 1901 as column chromatography for the separation of plant pigments, separation science has developed many diversified branches, each of which has its advantages, limitations, and fields of application. This book explores many aspects of separation science. For example, Dr. Leslie Ettre discusses the development of chromatography in the twentieth century, a period that witnessed the emergence, development, and dominance of separation science as an analytical technique. Today, chromatography and electrophoresis are ‘‘must’’ techniques in the analytical laboratory, a topic further explored in Professor Johan Roeraade’s chapter, ‘‘From Crushed Bricks to Microchips,’’ which delineates the major developments in separation science. |

The new digital radio system DAB (Digital Audio Broadcasting), developed within the Eureka 147 project in close cooperation with the EBU, is a very innovative and universal multimedia broadcast system that is just being introduced, and which has the potential to replace existing AM and FM audio broadcast services in many parts of the world in the near future. In several countries in Europe and overseas, broadcasting organisations, network providers and receiver manufacturers are already implementing digital broadcasting services using the DAB system. DAB is very different from conventional analogue broadcasting systems. Most of the system components such as perceptual audio coding (MPEG-1/2), OFDM channel coding and modulation, the provision of a multiplex of several services and data transmission protocols (MOT), are new concepts typical of digital broadcasting. Even experts in analogue transmission systems will feel less familiar with these new elements of broadcasting technology. Therefore, the aim of this book is to inform the expert reader about the basic concepts of the DAB system. |

The aim of this book is to provide reliable information not only on the science of crystallization from solution and from melt but also on the basic design methods for laboratory and especially industrial crystallizers. Up to now the niche between scientific results and practical design and operation of large-scale crystallizers has scarcely been filled. A work devoted to this objective has to take into account relevant crystallization phenomena as well as chemical engineering processes such as fluid dynamics, multiphase flow, and heat and mass transfer. |
