Explores the impact of the latest breakthroughs in cluster SIMS technology Cluster secondary ion mass spectrometry (SIMS) is a high spatial resolution imaging mass spectrometry technique, which can be used to characterize the three-dimensional chemical structure in complex organic and molecular systems. It works by using a cluster ion source to sputter desorb material from a solid sample surface. Prior to the advent of the cluster source, SIMS was severely limited in its ability to characterize soft samples as a result of damage from the atomic source. Molecular samples were essentially destroyed during analysis, limiting the method's sensitivity and precluding compositional depth profiling. The use of new and emerging cluster ion beam technologies has all but eliminated these limitations, enabling researchers to enter into new fields once considered unattainable by the SIMS method. With contributions from leading mass spectrometry researchers around the world, Cluster Secondary Ion Mass Spectrometry: Principles and Applications describes the latest breakthroughs in instrumentation, and addresses best practices in cluster SIMS analysis. It serves as a compendium of knowledge on organic and polymeric surface and in-depth characterization using cluster ion beams. It covers topics ranging from the fundamentals and theory of cluster SIMS, to the important chemistries behind the success of the technique, as well as the wide-ranging applications of the technology. Examples of subjects covered include: Cluster SIMS theory and modeling Cluster ion source types and performance expectations Cluster ion beams for surface analysis experiments Molecular depth profiling and 3-D analysis with cluster ion beams Specialty applications ranging from biological samples analysis to semiconductors/metals analysis Future challenges and prospects for cluster SIMS This book is intended to benefit any scientist, ranging from beginning to advanced in level, with plenty of figures to help better understand complex concepts and processes. In addition, each chapter ends with a detailed reference set to the primary literature, facilitating further research into individual topics where desired. Cluster Secondary Ion Mass Spectrometry: Principles and Applications is a must-have read for any researcher in the surface analysis and/or imaging mass spectrometry fields.

Mucoadhesive Materials and Drug Delivery Systems
Mucoadhesion defined as attachment of synthetic or natural materials to mucosal tissues has been widely exploited in pharmaceutical forms. This multi-author book provides an up-to-date account of current research on mucoadhesive materials and drug delivery systems. The introductory section describes the structure and physiology of various mucosal surfaces (oral, nasal, ocular, gastrointestinal and vaginal mucosa). This is followed by chapters on the various methods used to study mucoadhesion and to characterise mucoadhesive properties of various dosage forms. The final section will summarise information on traditional and novel types of mucoadhesive materials, such as chitosan, thiomers, and liposome-based formulations. This book is unique as there is currently no modern book considering mucoadhesion – all other existing books on the topic are either narrowly focused or more than 10 years old. Furthermore, each contributor offers specialist perspectives from a variety of global locations in both industrial and academic research centres.
Geographical Information Retrieval in Textual Corpora
This book addresses the field of geographic information extraction and retrieval from textual documents. Geographic information retrieval is a rapidly emerging subject, a trend fostered by the growing power of the Internet and the emerging possibilities of data dissemination. After positioning his work in this field in Chapter 1, the author makes proposals in the following two chapters. Chapter 2 focuses on spatial and temporal information indexing and retrieval in corpora of textual documents. Propositions for both spatial and temporal information retrieval (IR) are made. Chapter 3 tackles the use of generalized spatial and temporal indexes, which are produced from there in the framework of multi-criteria IR. Geographic IR (GIR) is discussed at length, since this IR combines the criteria of spatial, temporal and thematic research. The author provides a rich bibliographical study of the current approaches focused on the modeling and retrieval of spatial and temporal information in textual documents, and similarity measures developed thus far in the literature. The book concludes with a broad perspective of the remaining scientific challenges. Several areas of research are discussed, such as integration of a domain-based ontology, modeling of spatial footprints from the interpretation of spatial relation, and parsing of relations between features deemed relevant within a document resulting from a GIR process. Contents Foreword, Christophe Claramunt. 1. Access by Geographic Content to Textual Corpora: What Orientations ? 2. Spatial and Temporal Information Retrieval in Textual Corpora. 3. Multicriteria Information Retrieval in Textual Corpora. 4. General Conclusion. About the Authors Christian Sallaberry is currently Assistant Professor at the Law, Economics and Management Faculty in Pau, France. His current research interests are in the fields of geographical information retrieval (GIR) in textual corpora: spatial, temporal and thematic information recognition, analyzing, indexing and retrieval. He is interested in spatial, temporal and thematic criteria combinations within a GIR process.

Fundamentals of the Physical Theory of Diffraction
The book is a complete, comprehensive description of the modern Physical Theory of Diffraction (PTD) based upon the concept of elementary edge waves. The theory is demonstrated with examples of the diffraction of acoustic and electromagnetic waves at perfectly reflecting objects. Readers develop the skills to apply PTD to solve various scattering problems. The derived analytic expressions clearly illustrate the physical structure of the scattered field. They additionally describe all of the reflected and diffracted rays and beams, as well as the fields in the vicinity of caustics and foci. Shadow radiation, a fundamental component of PTD, is introduced and proven to contain half the total scattered power. The equivalence relationships between acoustic and electromagnetic diffracted waves are established and emphasized. Throughout the book, the author enables readers to master both the theory and its practical applications. Plotted numeric results supplement the theory and facilitate the visualization of individual contributions of distinct parts of the scattering objects to the total diffracted field Detailed comments help readers understand and implement all the critical steps of the analytic and numeric calculations Problem sets in each chapter give readers an opportunity to analyse and investigate the diffraction phenomena
