Some well-known age-related neurological diseases include Parkinson's disease, Alzheimer's disease, deafness, and blindness. Even more common are the problems of aging which are not due to disease but to more subtle impairments in neurobiological systems, including impairments in vision, memory loss, muscle weakening, and loss of reproductive functions, changes in body weight, and sleeplessness. As the average age of our society increases, diseases of aging continue to become more common, and conditions associated with aging need more attention by doctors and researchers. In 1991, patients over the age of 65 saw their doctors an average of eight times per year. Research funding is provided by the Neuroscience and Neuropsychology of Aging (NNA) Program, which is run by the National Institute on Aging. This book offers a comprehensive overview of all topics related to functional impairments which are related to the aging brain and nervous system. It is organized according to four general functions: movement, senses, memory, and neuroendocrine regulation. Written by the leading researchers in the field, this comprehensive work addresses both impairments associated with diseases and not associated with diseases, making it easier to understand the mechanisms involved. Functional Neurobiology of Aging is an important reference for professionals and students involved in aging research, as well as physicians who need to recognize and understand age-related impairments.
Key Features
* Organized by function, making it easy to find and understand the material
* Addresses impairments both associated with diseases and not associated with diseases
* Written by leading researchers in the field

In the thirty-seven years that have gone by since the first volume of Progress in Optics was published, optics has become one of the most dynamic fields of science. At the time of inception of this series, the first lasers were only just becoming operational, holography was in its infancy, subjects such as fiber optics, integrated optics and optoelectronics did not exist and quantum optics was the domain of only a few physicists. The term photonics had not yet been coined. Today these fields are flourishing and have become areas of specialisation for many science and engineering students and numerous research workers and engineers throughout the world. Some of the advances in these fields have been recognized by awarding Nobel prizes to seven physicists in the last twenty years. The volumes in this series which have appeared up to now contain nearly 190 review articles by distinguished research workers, which have become permanent records for many important developments. They have helped optical scientists and optical engineers to stay abreast of their fields. There is no sign that developments in optics are slowing down or becoming less interesting. We confidently expect that, just like their predecessors, future volumes of Progress in Optics will faithfully record the most important advances that are being made in optics and related fields.

Considerable evidence exists that visual sensory information is analyzed simultaneously along two or more independent pathways. In the past two decades, researchers have extensively used the concept of parallel visual channels as a framework to direct their explorations of human vision. More recently, basic and clinical scientists have found such a dichotomy applicable to the way we organize our knowledge of visual development, higher order perception, and visual disorders, to name just a few. This volume attempts to provide a forum for gathering these different perspectives.

This book contains 15 fully peer-reviewed Invited Papers which were presented at the 13th Biennial European Conference on Fracture and is a companion to the CD-ROM http: //www.elsevier.com/locate/isbn/008043701xProceedings.
The organisers of the ECF 13 opted from the very beginning for an application-orientated conference, and consequently, this book contributes to the understanding of fracture phenomena, and disseminates fracture concepts and their application to the solution of engineering problems to practitioners in a wide range of fields.
The fields covered in this book can be broadly classified into: elastic-plastic fracture mechanics, fracture dynamics, fatigue and interactive processes, failure, structural integrity, coatings and materials, with applications to the following industrial sectors: transport, aerospace engineering, civil engineering, pipelines and automotive engineering.

This book is divided into five sections dealing with various fundamental issues in current research: attention, information processing and eye movement control; the role of phonology in reading; syntax and discourse processing and computational models and simulations. Control and measurement of eye movements form a prominent theme in the book. A full understanding of the where and when of eye movement control is a prerequisite of any complete theory of reading, since it is precisely at this point that perceptual and cognitive processes interact.

Amongst the 'hot topics' included are the relation between parafoveal and foveal visual processing of linguistic information, the role of phonology in fluent reading and the emergence of statistical 'tuning' approaches to sentence parsing.

Also discussed in the book are three attempts to develop quantitative models of reading which represent a significant departure in theory-building and a quantum step in the maturation of reading research.

Much of the work reported in the book was first presented at the 5th European Workshop on Language Comprehension organised in April 1998 which was held at the CNRS Luminy Campus, near Marseilles. All contributions summarise the state-of-the-art in the relevant areas of reading research.

This book is a continuation of 'Acoustic and Elastic Wave Fields in Geophysics, Part I' published in 2000. The second volume is dedicated to propagation of linear plane, spherical and cylindrical acoustic waves in different media. Chapter 1 is devoted to principles of geometric acoustic in plane wave approximation. The eikonal and transport equations are derived. Ray tracing and wavefront construction techniques are explained. Chapter 2 deals with dynamic properties of wave fields. The behavior of pressure and displacements amplitudes in zero approximation is analysed in two ways: using Poynting vector and solving the transport equation. This chapter contains several examples related to shadow zones and caustics. In Chapter 3 using the results of analysis of high-frequency wave kinematics and dynamics some fundamental aspects of Kirchhoff migration are described. Chapters 4 and 5 are devoted to propagation of plane waves in media with flat boundaries in the case of normal and oblique incidence. Special attention is paid to the case when an incident angle exceeds the critical angles. Formation of normal modes in the waveguide is discussed. Chapter 6 deals with a spherical wave reflection and refraction. The steepest descent method is introduced to describe the behavior of reflected, transmitted, head and evanescent waves. In Chapter 7 propagation of stationary and transient waves in a waveguide formed by a flat layer with low velocity are investigated. Normal modes and waves related to the branch points of integrands under consideration are studied. Dispersive properties of normal modes are discussed. Chapter 8 describes wave propagation inside cylinder in acoustic media. Several appendices are added to help the reader understand different aspects of mathematics used in the book.

The collection of chapters in the "Handbook of Population and Family Economics" and their organization reflect the most recent developments in economics pertaining to population issues and the family. The rationale, contents, and organization of the "Handbook" evolve from three premises. First, the family is the main arena in which population outcomes are forged. Second, there are important interactions and significant causal links across all demographic phenomena. Third, the study of the size, composition, and growth of a population can benefit from the application of economic methodology and tools. The diversity and depth of the work reviewed and presented in the "Handbook" conveys both the progress that has been made by economists in understanding the forces shaping population processes, including the behavior of families, and the many questions, empirical and theoretical, that still remain.

The Seventh International Conference series on Vision in Vehicles was held in Marseilles in September 1997. This event was run in conjunction with the Applied Vision Association, the Ergonomics Society and with the participation of INRETS (Institut National de Recherche sur les Transports et leur Securite).
This volume presents the selected and edited proceedings. The papers at the conference were ordered into sessions, from driver-specific aspects to interfacing with the new in-vehicle systems. These sessions are mirrored in the ordering of the chapters. The conference is long established and regularly draws representatives from the key international research centres working in this popular and diverse transportation area.

The book focuses on a conceptual flaw in contemporary artificial intelligence and cognitive science. Many people have discovered diverse manifestations and facets of this flaw, but the central conceptual impasse is at best only partially perceived. Its consequences, nevertheless, visit themselves as
distortions and failures of multiple research projects - and make impossible the ultimate aspirations of the fields.

The impasse concerns a presupposition concerning the nature of representation - that all representation has the nature of encodings: encodingism. Encodings certainly exist, but
encoding"ism" is at root logically incoherent; any "programmatic" research predicted on it is doomed too distortion and ultimate failure.

The impasse and its consequences - and steps away from that impasse - are explored in a large number of projects and approaches. These include SOAR, CYC, PDP, situated cognition, subsumption architecture robotics, and the frame problems - a general survey of the current research in AI and Cognitive Science emerges.

Interactivism, an alternative model of representation, is proposed and examined.

This classic work has been fundamentally revised to take account of recent developments in general topology. The first three chapters remain unchanged except for numerous minor corrections and additional exercises, but chapters IV-VII and the new chapter VIII cover the rapid changes that have occurred since 1968 when the first edition appeared.
The reader will find many new topics in chapters IV-VIII, e.g. theory of Wallmann-Shanin's compactification, realcompact space, various generalizations of paracompactness, generalized metric spaces, Dugundji type extension theory, linearly ordered topological space, theory of cardinal functions, dyadic space, etc., that were, in the author's opinion, mostly special or isolated topics some twenty years ago but now settle down into the mainstream of general topology.

The present volume is the first in the advances in oncobiology series. It is meant to be useful not only to clinical and non-clinical oncologists but also to graduate students and medical students.

ICSAS '99 - The Fourth International Conference on Steel and Aluminium Structures was a sequel to ICSAS '87 held in Cardiff, UK, to ICSAS '91 held in Singapore and to ICSAS '95 held in Istanbul, Turkey. The objective of the conference was to provide a forum for the discussion of recent findings and developments in the design and construction of various types of steel and aluminium structures.

The conference was concerned with the analysis, modelling and design of light-weight or slender structures in which the primary material is structural steel, stainless or aluminium. The structural analysis papers presented at the conference cover both static and dynamic behaviour, instability behaviour and long-term behaviour under hygrothermal effects. The results of the latest research and development of some new structural products were also presented at the conference. A total of 76 papers and 30 posters were presented at the conference by participants from 36 countries in all 6 continents.

The most exciting development in parallel computer architecture is the convergence of traditionally disparate approaches on a common machine structure. This book explains the forces behind this convergence of shared-memory, message-passing, data parallel, and data-driven computing architectures. It then examines the design issues that are critical to all parallel architecture across the full range of modern design, covering data access, communication performance, coordination of cooperative work, and correct implementation of useful semantics. It not only describes the hardware and software techniques for addressing each of these issues but also explores how these techniques interact in the same system. Examining architecture from an application-driven perspective, it provides comprehensive discussions of parallel programming for high performance and of workload-driven evaluation, based on understanding hardware-software interactions.
