Cell Traffic


Book Description

Cell Traffic presents new poems and uncollected prose poetry along with selected work from award-winning poet Heid Erdrich's three previous poetry collections. Erdrich's new work reflects her continuing concerns with the tensions between science and tradition, between spirit and body. She finds surprising common ground while exploring indigenous experience in multifaceted ways: personal, familial, biological, and cultural. The title, Cell Traffic, suggests motion and Erdrich considers multiple movements-cellular transfer, the traffic of DNA through body parts and bones, "migration" through procreation, and the larger "movements" of indigenousness and ancestral inheritance. Erdrich's wry sensibility, sly wit, and keenly insightful mind have earned her a loyal following. Her point of view is always slightly off center, and this lends a particular freshness to her poetry. The debunking and debating of the science of origins is one of Erdrich's focal subjects. In this collection, she turns her observational eye to the search for a genetic mother of humanity, forensic anthropology's quest for the oldest known bones, and online offers of genetic testing. But her interests are not limited to science. She freely admits popular culture into her purview as well, referencing sci-fi television series and Internet pop-up ads.

The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.




Transport And Diffusion Across Cell Membranes


Book Description

Transport and Diffusion across Cell Membranes is a comprehensive treatment of the transport and diffusion of molecules and ions across cell membranes. This book shows that the same kinetic equations (with appropriate modification) can describe all the specialized membrane transport systems: the pores, the carriers, and the two classes of pumps. The kinetic formalism is developed step by step and the features that make a system effective in carrying out its biological role are highlighted. This book is organized into six chapters and begins with an introduction to the structure and dynamics of cell membranes, followed by a discussion on how the membrane acts as a barrier to the transmembrane diffusion of molecules and ions. The following chapters focus on the role of the membrane's protein components in facilitating transmembrane diffusion of specific molecules and ions, measurements of diffusion through pores and the kinetics of diffusion, and the structure of such pores and their biological regulation. This book methodically introduces the reader to the carriers of cell membranes, the kinetics of facilitated diffusion, and cotransport systems. The primary active transport systems are considered, emphasizing the pumping of an ion (sodium, potassium, calcium, or proton) against its electrochemical gradient during the coupled progress of a chemical reaction while a conformational change of the pump enzyme takes place. This book is of interest to advanced undergraduate students, as well as to graduate students and researchers in biochemistry, physiology, pharmacology, and biophysics.




Fundamentals of 5G Mobile Networks


Book Description

Fundamentals of 5G Mobile Networks provides an overview of the key features of the 5th Generation (5G) mobile networks, discussing the motivation for 5G and the main challenges in developing this new technology. This book provides an insight into the key areas of research that will define this new system technology paving the path towards future research and development. The book is multi-disciplinary in nature, and aims to cover a whole host of intertwined subjects that will predominantly influence the 5G landscape, including the future Internet, cloud computing, small cells and self-organizing networks (SONs), cooperative communications, dynamic spectrum management and cognitive radio, Broadcast-Broadband convergence , 5G security challenge, and green RF. This book aims to be the first of its kind towards painting a holistic perspective on 5G Mobile, allowing 5G stakeholders to capture key technology trends on different layering domains and to identify potential inter-disciplinary design aspects that need to be solved in order to deliver a 5G Mobile system that operates seamlessly.




QoS and QoE Management in UMTS Cellular Systems


Book Description

This comprehensive volume provides state-of-the art guidance on Quality of Service (QoS) and Quality of end-user Experience (QoE) management in UMTS cellular systems, tackling planning, provisioning, monitoring and optimisation issues in a single accessible resource. In addition, a detailed discussion is provided on service applications, QoS concept, architecture and functions in access, packet & circuit switched core and backbone networks. Defines and explains the differences between QoS and QoE, and end-to-end concept, based on the premise that it is the end-user who is the ultimate beneficiary of QoS. Covers QoS and QoE issues related to present and forthcoming service applications, including multimedia messaging service (MMS), Video Sharing (VS), content download, business connectivity, Push to talk over Cellular (PoC), Voice over IP (VoIP), presence, instant messaging, gaming, streaming and browsing. Presents QoS concepts and architecture as defined in 3GPP Releases 97/98, 99, 5, 6, and 7, and provides a comprehensive description of protocols and packet data transfer across WCDMA evolved and (E)GPRS networks.

Understanding Mobilities for Designing Contemporary Cities


Book Description

This book explores mobilities as a key to understanding the practices that both frame and generate contemporary everyday life in the urban context. At the same time, it investigates the challenges arising from the interpretation of mobility as a socio-spatial phenomenon both in the social sciences and in urban studies. Leading sociologists, economists, urban planners and architects address the ways in which spatial mobilities contribute to producing diversified uses of the city and describe forms and rhythms of different life practices, including unexpected uses and conflicts. The individual sections of the book focus on the role of mobility in transforming contemporary cities; the consequences of interpreting mobility as a socio-spatial phenomenon for urban projects and policies; the conflicts and inequalities generated by the co-presence of different populations due to mobility and by the interests gathered around major mobility projects; and the use of new data and mapping of mobilities to enhance comprehension of cities. The theoretical discussion is complemented by references to practical experiences, helping readers gain a broader understanding of mobilities in relation to the capacity to analyze, plan and design contemporary cities.
