Map Use: Reading, Analysis, Interpretation, seventh edition, is a comprehensive, foundational textbook designed for the college curriculum. Now updated with a new section on map interpretation, Map Use provides students with the knowledge and skills to read and understand maps, and offers professional cartographers a thorough reference resource. Nearly 600 full-color maps, photographs, and graphs illustrate the concepts behind communicating with maps, while an extensive glossary and resource DVD for instructors (lecture slides, lab exercises, and answer keys) further support use of the text in the classroom. The book renders basic cartographic principles accessible to all, from students of cartography and map design to those without a formal education in geography. Accommodating new developments in GPS and geographic information system technology, this newest edition could serve as an introductory GIS text as well.
Today, increasing demands and expectations are being placed on GPS systems. Assisted GPS (A-GPS) has been developed to provide greatly improved capabilities, helping GPS work better and faster in almost any location. Offering a detailed look at all the technical aspects and underpinnings of A-GPS, this unique book places emphasis on practical implementation. The book reviews standard GPS design, helping professionals understand why GPS requires assistance in the first place. Readers discover how A-GPS enables the computing of a position from navigation satellites in the absence of precise time - a topic not covered in any other book. Moreover, engineers learn how to design and analyze a high sensitivity GPS receiver and determine the achievable sensitivity of a GPS receiver.
This book provides an update and detailed review of our knowledge about the newly identified diverse functions of semaphorins, including their potential therapeutic applications. Although semaphorins were originally identified as repulsive axon guidance molecules that were required to direct neuronal axons to their appropriate targets, more than 20 types of semaphorin have since been discovered. Several members of semaphorins, so-called "immune semaphorins," are critical to various phases of the immune response by regulating immune cell-cell contacts or cell migration. In recent years it has also become apparent that semaphorins perform multiple functions in a range of physiological processes, including cardiogenesis, angiogenesis, vasculogenesis, osteoclastogenesis, and immune regulation. In addition, we now know that semaphorins and their receptors can be a potential therapeutic target for various human diseases, including tumorigenesis/tumor metastasis and, neuroregenerative diseases, sudden death and immune disorders. Comprehensive functions of semaphorins have been discovered in many biological mechanisms.
