This brief explores the utilization of large antenna arrays in massive multiple-input-multiple-output (MIMO) for both interference suppression, where it can improve cell-edge user rates, and for wireless backhaul in small cell networks, where macro base stations can forward data to small access points in an energy efficient way. Massive MIMO is deemed as a critical technology for next generation wireless technology. By deploying an antenna array that has active elements in excess of the number of users, massive MIMO not only provides tremendous diversity gain but also powers new aspects for network design to improve performance. This brief investigates a better utilization of the excessive spatial dimensions to improve network performance. It combines random matrix theory and stochastic geometry to develop an analytical framework that accounts for all the key features of a network, including number of antenna array, base station density, inter-cell interference, random base station deployment, and network traffic load. The authors explore the impact from different network parameters through numerical analysis.Researchers in wireless network design will find this to be an exceptional resource, as will advanced-level students or professionals working in networking and information systems design.
Chemometrics in Spectroscopy, Revised Second Edition provides the reader with the methodology crucial to apply chemometrics to real world data. The book allows scientists using spectroscopic instruments to find explanations and solutions to their problems when they are confronted with unexpected and unexplained results. Unlike other books on these topics, it explains the root causes of the phenomena that lead to these results. While books on NIR spectroscopy sometimes cover basic chemometrics, they do not mention many of the advanced topics this book discusses. This revised second edition has been expanded with 50% more content on advances in the field that have occurred in the last 10 years, including calibration transfer, units of measure in spectroscopy, principal components, clinical data reporting, classical least squares, regression models, spectral transfer, and more. - Written in the column format of the authors' online magazine - Presents topical and important chapters for those involved in analysis work, both research and routine - Focuses on practical issues in the implementation of chemometrics for NIR Spectroscopy - Includes a companion website with 350 additional color figures that illustrate CLS concepts
Escherichia coli, commonly referred to as E. coli, has been the organism of choice for molecular genetics for decades. Its machinery and mobile behavior is one of the most fascinating topics for cell scientists. Scientists and engineers, not trained in microbiology, and who would like to learn more about living machines, can see it as a unique example. This cross-disciplinary monograph covers more than thirty years of research and is accessible to graduate students and scientists alike.
Nucleotide Sequences 1986/1987, Volume VII: Structural RNA, Synthetic, and Unannotated Sequences presents data that reflect the information found in GenBank Release 44.0 of August 1986. This book provides information pertinent to the unique international collaboration between two leading nucleotide sequence data libraries, one based in Europe and one in the United States. Organized into three sections, this volume begins with an overview of the sequences, some basic identifying information, and some of the biological annotations. This text then discusses the EMBL Nucleotide Sequence Data Library, an international center of fundamental research with its main focus in the fields of cell biology, molecular structures, instrumentation, and differentiation. This book discusses as well the GenBank database established in 1982 by the National Institute of General Medical Sciences (NIGMS) of the U.S National Institutes of Health (NIH). This book is a valuable resource for molecular biologists and other investigators collecting the large number of reported DNA and RNA sequences and making them available in computer-readable form.
Issues relating to the high-K gate dielectric are among the greatest challenges for the evolving International Technology Roadmap for Semiconductors (ITRS). More than just an historical overview, this book will assess previous and present approaches related to scaling the gate dielectric and their impact, along with the creative directions and forthcoming challenges that will define the future of gate dielectric scaling technology. Topics include: an extensive review of Moore's Law, the classical regime for SiO2 gate dielectrics; the transition to silicon oxynitride gate dielectrics; the transition to high-K gate dielectrics (including the drive towards equivalent oxide thickness in the single-digit nanometer regime); and future directions and issues for ultimate technology generation scaling. The vision, wisdom, and experience of the team of authors will make this book a timely, relevant, and interesting, resource focusing on fundamentals of the 45 nm Technology Generation and beyond.

The book will also benefit individuals in environmental, regulatory, and registration affairs, as well as academicians and students.
As the theoretical foundations of multiple-antenna techniques evolve and as these multiple-input multiple-output (MIMO) techniques become essential for providing high data rates in wireless systems, there is a growing need to understand the performance limits of MIMO in practical networks. To address this need, MIMO Communication for Cellular Networks presents a systematic description of MIMO technology classes and a framework for MIMO system design that takes into account the essential physical-layer features of practical cellular networks. In contrast to works that focus on the theoretical performance of abstract MIMO channels, MIMO Communication for Cellular Networks emphasizes the practical performance of realistic MIMO systems. A unified set of system simulation results highlights relative performance gains of different MIMO techniques and provides insights into how best to use multiple antennas in cellular networks under various conditions. MIMO Communication for Cellular Networks describes single-user, multiuser, network MIMO technologies and system-level aspects of cellular networks, including channel modeling, resource scheduling, interference mitigation, and simulation methodologies. The key concepts are presented with sufficient generality to be applied to a wide range of wireless systems, including those based on cellular standards such as LTE, LTE-Advanced, WiMAX, and WiMAX2. The book is intended for use by graduate students, researchers, and practicing engineers interested in the physical-layer design of state-of-the-art wireless systems.
