Understanding ion channel gating has been a goal of researchers since Hodgkin and Huxley's classic publication in 1952, but the gating mechanism has remained elusive. In this book, it is shown how electrons can control gating. Introducing the electron as a gating agent requires amplification, but until now there has been no appropriate mechanism for amplification.The new approach to gating, based on the electron and quantum mechanics, elucidates mechanisms important to cellular function and signaling. A greater understanding of the quantum-mechanical mechanisms and the role of the electron will likely bring benefits to human health, including improvements in drug therapy and treatments for ion channel related diseases.Ion channel gating influences many cellular processes and is at the center of electrical and calcium signaling in the nervous system. The gating of ion channels has been intensively investigated over the past 15-20 years and a number of models have been proposed for gating.For the first time, this book presents a comprehensive analysis, based on electrons controlling the ion channel gates. The theory and gating model are extensively linked to published experimental observations. The intrinsic simplicity of electron gating elucidates mechanisms important to the functions of nerve cells.A NEW APPROACHThe new approach to gating, based on the electron and quantum mechanics, elucidates mechanisms important to cellular functioning and signaling. A greater understanding of the quantum-mechanical mechanisms and the role of the electron will likely bring benefits to human health, including improvements in drug therapy and treatments for ion channel related diseases, such as: 1. Cardiac arrhythmias, Long QT syndrome and Brugada syndrome may result from genetic mutations in sodium, potassium or L-type calcium channels that alter gating and timing. Electron-Gated Ion Channels explains long time intervals between open and closed states. A model for L-type calcium oscillators (Chapter 8), based on voltage-sensitive electron tunneling, show how burst mode oscillations can occur in pacemaker cells. This may help to understand a variation in timing intervals caused by some genetic mutations. 2. Hypokalemic periodic paralysis (HypoPP) is a muscle disorder reported to be caused by inherited mutations in the voltage sensor (S4) of a sodium or calcium channel. Electron-Gated Ion Channels suggests how a shift in the activation curve or change in inactivation time may result from S4 mutations that alter voltage sensitivity or the electron tunneling distance between arginine and lysine sites. 3. Epilepsy, schizophrenia and Alzheimer s disease are reported to have changes in the theta rhythm (4 - 12 Hz). Electron gating models show how theta and alpha waves in the brain are likely produced by electron tunneling oscillations in the voltage sensor of calcium or sodium ion channels. An L-type calcium oscillator model (Chapter 8) provides a 4 - 12 Hz oscillation frequency with an 8-residue tunneling distance between arginine and lysine sites at the cytoplasmic end of S4 in domain IV.KEY FEATURES A comprehensive analysis of ion channel gating, based on amplified single-electron tunneling. Microwave Thermal Fluorescence Spectroscopy experiments show, for the first time, spectra for quantum states of inverting NH3 on arginine s side chain. Amplification of 25 fold, based on NH3 inversion, provides the voltage sensitivity for 4 tunneling electrons to control all sodium, potassium and calcium channel gates. Explains long time-constants for ion channel inactivation and the immobilization of gating charge. Single-electron tunneling with long time-constant inactivation provides a simple mechanism for producing burst-mode oscillations in L-type calcium channels."

Personal multimedia communication is "the" major growth area in
engineering today with many people across the world in industry and
academia working on the design of future generations of mobile
radio systems and source coding methods. Before multimedia
applications can be truly successful in mobile environments, many
technologically demanding problems must be resolved. In order to
provide the user with a suitable end-to-end service for multimedia
applications, complex systems, interfaces and coding schemes need
to be developed. In mobile multimedia, the air interface bandwidth
requirements are likely to be dominated by the needs of one key
service: video. Even with today's most aggressive compression
algorithms, the needs of video exceed the bandwidth available with
existing mobile connections. Although available bandwidth will
increase, with the introduction of UMTS and local services based on
wireless LANs (such as HiperLan), it is clear that advances in
radio technology and air interface design must go hand in hand with
innovations in source and channel coding.

The theory of complex Ginzburg-Landau type phase transition and its applica tions to superconductivity and superfluidity has been a topic of great interest to theoretical physicists and has been continuously and persistently studied since the 1950s. Today, there is an abundance of mathematical results spread over numer ous scientific journals. However, before 1992, most of the studies concentrated on formal asymptotics or linear analysis. Only isolated results by Berger, Jaffe and Taubes and some of their colleagues touched the nonlinear aspects in great detail. In 1991, a physics seminar given by Ed Copeland at Sussex University inspired Q. Tang, the co-author of this monograph, to study the subject. Independently in Munich, K.-H. Hoffmann and his collaborators Z. Chen and J. Liang started to work on the topic at the same time. Soon it became clear that at that time, groups of mathematicians at Oxford and Virginia Tech had already studied the subject for a couple of years. They inspired experts in interface phase transition problems and their combined effort established a rigorous mathematical framework for the Ginzburg-Landau system. At the beginning Q. Tang collaborated with C.M. Elliott and H. Matano."

The protection which is installed on an industrial power system is likely to be subjected to more difficult conditions than the protection on any other kind of power system. Starting with the many simple devices which are employed and covering the whole area of industrial power system protection, this book aims to help achieve a thorough understanding of the protection necessary. Vital aspects such as the modern cartridge fuse, types of
relays, and the role of the current transformer are covered and the
widely used inverse definite-minimum time overcurrent relay, the
theory of the Merz-Price protection system and the development of
the high-impedance relay system are critically examined. This new
edition has come about in response to the dramatic change from the
use of electro-magnetic relays to electronic and micro-processor
relays which figure in practically all new installations.
Therefore, although the theory and usage are the same, the
application can be much improved owing to the increased range and
accuracy and the added facilities provided with the modern relays.
This book reflects the change and explains the technical
advantages.
Recent years have brought substantial developments in electrical

This book focuses on near-zero energy buildings (NZEBs), smart communities and microgrids. In this context, demand response (DR) is associated with significant environmental and economic benefits when looking at how electricity grids, communities and buildings can operate optimally. In DR, the consumer becomes a prosumer with an important active role in the exchange of energy on an hourly basis. DR is gradually gaining ground with respect to the reduction of peak loads, grid balancing and dealing with the volatility of renewable energy sources (RES). This transition calls for high environmental awareness and new tools or services that will improve the dynamic as well as secure multidirectional exchange of energy and data. Overall, DR is identified as an important field for technological and market innovations aligned with climate change mitigation policies and the transition to sustainable smart grids in the foreseeable future. Smart Buildings, Smart Communities and Demand Response provides an insight into various intrinsic aspects of DR potential, at the building and the community level.

Intelligent agents are one of the most promising business tools in our information rich world. An intelligent agent consists of a software system capable of performing intelligent tasks within a dynamic and unpredictable environment. They can be characterised by various attributes including: autonomous, adaptive, collaborative, communicative, mobile, and reactive. Many problems are not well defined and the information needed to make decisions is not available. These problems are not easy to solve using conventional computing approaches. Here, the intelligent agent paradigm may play a major role in helping to solve these problems. This book, written for application researchers, covers a broad selection of research results that demonstrate, in an authoritative and clear manner, the applications of agents within our information society.
