Much mathematical modelling has involved the assumption that physical systems are approximately linear, leading to the construction of equations which, although relatively easy to solve, are unrealistic and overlook significant phenomena. Models assuming nonlinear systems, however, lead to the emergence of new structures that reflect reality much more closely. This second edition of Nonlinear Science, covers several important areas of nonlinear science, and places a strong emphasis on applications to realistic problems. It includes numerous new topics such as empirical results in molecular dynamics, solid-state physics, neuroscience, fluid dynamics, and biophysics; numerous new exercises and solutions; updated sections on nerve impulse dynamics, quantum-theory of pump-probe measures, and local modes on lattices. With over 350 problems, including hints and solutions, this is an invaluable resource for graduate students and researchers in the applied sciences, mathematics, biology, physics and engineering.This is the latest title in the Oxford Texts in Applied and Engineering Mathematics, which includes a range of texts from the undergraduate through to the graduate level. Most titles should be based on taught courses which explain the mathematical or computational techniques required for the resolution of fundamental applied problems. Other books in the series include: D. W. Jordan and P. Smith: Nonlinear ordinary differential equations: an introduction to dynamical systems 3rd Edition; I. J. Sobey: Introduction to interactive boundary layer theory; A. B. Tayler: Mathematical Models in Applied Mechanics (reissue); Ramdas Ram-Mohan: Finite Element and Boundary Element Applications in Quantum Mechanics; Lapeyre et al: Introduction to Monte-Carlo Methods for Transport and Diffusion Equations; Isaac Elishakoff & Yong Jin Ren: Finite Element Methods for Structures with Large Stochastic Variations

Arguably the most intricate dynamic object in the universe, the human brain is an unsounded source of wonder for the scienti?c community. The primary aim of this book is to provide both students and established - vestigators in the growing area of neuroscience with an appreciation of the roles that mathematics may play in helping to understand this en- maticorgan. Alongwithdiscussionsofresultsobtainedbytheneuroscience community, emphasis is placed on suggesting fruitful research problems for those planning to embark on mathematical studies in neuroscience. To make the overall perspectives understandable to philosophers and psychologists, essential features of the discussions are presented in ordinary English, with more detailed mathematical comments in appendices and footnotes. Although it attempts to maintain both clarity and biological relevance, this is not a text on the anatomy of nerve systems; thus readers should bring some knowledge of neurophysiology through other courses, associated studies, or laboratory research. It is a guiding theme throughout the book that the brain is organized into several quite di?erent levels of dynamic activity. As will be seen, these levels are hierarchically structured, beginning with the molecular dynamics ofintrinsicmembraneproteinsandproceedingupward,throughtheswit- ing properties of active membrane patches and synapses, the emergence of impulses on active ?bers, overall properties of individual neurons, and the growth of functional assemblies of interacting neurons, to the global - namics of a brain. At each level of description, reality turns di?erent facets of her mystery to us, and diverse phenomena make their contributions to the brain’s collective behavior.

Stairway to the Mind explores one of the most exciting and controversial areas of modern science: consciousness and the nature of the mind. The book proposes that consciousness emerges from hierarchical layers of mental reality, in the same way that life emerges from layers of biological reality. The book is aimed at general readers with an interest in the mind and neuroscience, as well as a wide range of scientists whose work is related to the rapidly-growing field of neuroscience and consciousness research.

This book is book aims to provide the beginner with a concise, practical and systematic guide to interpreting ECGs. It will serve not only as a starter text but also as an immediate bedside reference manual. Starting to Read ECGs: The Basics begins with fundamentals such as how to perform, record and interpret a normal ECG before progressing onto more complex topics, including what effects anatomical abnormalities of the heart, cardiac and non-cardiac conditions can have on the ECG. Each chapter has been supplemented with a multitude of images and diagrams to illustrate points and ease understanding, and concludes with both a summary of key points to reinforce knowledge and a quiz for reflective learning.Starting to Read ECGs: The Basics is an updated version of that previously published by CriticAir and an essential resource for medical students, junior doctors, nurses, paramedics and other health care professionals involved in the recording and interpretation of ECGs who wish to build their knowledge and confidence.

​​​The ECG is one of the most widely available diagnostic tests used in clinical practice today. This book is intended to build upon the topics covered in Starting to Read ECGs: The Basics thus allowing the reader to enhance their previous knowledge. Additional topics covered include a detailed look at calculating cardiac axis, an area often considered difficult to grasp, and alternative methods such as the various ways the heart rate can be calculated, the different criteria for determining LVH. Technical details about specific cardiac conditions, how to interpret pediatric ECGs, and the effect of medical devices on the ECG will also be discussed. Plentiful diagrams, tables and colour images used throughout to illustrate complex points in a simple and easy to understand way. The key facts section at the end of each chapter highlights the most important information and summary tables are provided to allow the book to be used as a quick reference guide. Each chapter will contain a mind map for revision and to aid dyslexic learners, practice questions and a few practice ECGs to consolidate the readers knowledge.The book tells the practitioner what they need to know clinically and doesn't assume any prior knowledge. It is ideal for junior doctors and clinicians, nurses, paramedics, students and health care professionals involved in the recording of 12-lead ECGs.
