High-Temperature Superconductivity in Cuprates

High-Temperature Superconductivity in Cuprates



The main purpose of the book is to present a description of the mechanism of high-temperature superconductivity and to discuss the physics of high-temperature superconductors, both entirely based on experimental facts. The pairing mechanism of this remarkable phenomenon is based on an anomaly found in tunneling (V) characteristics of some cuprates. By using the soliton theory, it is then shown that this anomaly is caused by pairs of quasi-one dimensional excitations – bisolitons – bound due to a moderately strong, nonlinear electron-phonon interaction. At the same time, analysis of experimental data unambiguously shows that magnetic (spin) fluctuations mediate the phase coherence in cuprates. The mechanism of superconductivity in quasi-one dimensional organic superconductors and heavy fermions is discussed too. In cuprates, the origins of five different energy/temperature scales are identified. Finally, three main principles of superconductivity are introduced at the end of the book. Analysis of tunneling and angle-resolved photoemission measurements is presented in the last chapter. The book which contains 300 pages with 180 illustrations is addressed to researchers and graduate students in all branches of exact sciences.

Molecular Imaging of the Brain

Molecular Imaging of the Brain



This book examines multi-quantum magnetic resonance imaging methods and the diagnostics of brain disorders. It consists of two Parts. The part I is initially devoted towards the basic concepts of the conventional single quantum MRI techniques. It is supplemented by the basic knowledge required to understand multi-quantum MRI. Practical illustrations are included both on recent developments in conventional MRI and the MQ-MRI. This is to illustrate the connection between theoretical concepts and their scope in the clinical applications. The Part II initially sets out the basic details about quadrupole charge distribution present in certain nuclei and their importance about the functions they perform in our brain. Some simplified final mathematical expressions are included to illustrate facts about the basic concepts of the quantum level interactions between magnetic dipole and the electric quadrupole behavior of useful nuclei present in the brain. Selected practical illustrations, from research and clinical practices are included to illustrate the newly emerging ideas and techniques. The reader should note that the two parts of the book are written with no interdependence. One can read them quite independently.

Sociology

Sociology



Drawing on studies of social class, crime and deviance, work in bureaucracies, and changes in religious and political organizations, this Very Short Introduction explores the tension between the individual’s role in society and society’s role in shaping the individual, and demonstrates the value of sociology as a perspective for understanding the modern world. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

The De-Mathematisation of Logic

The De-Mathematisation of Logic



This book collects together several articles by the author, to which a certain recent RATIO paper of his relates, with that paper as an introduction to the whole. It displays a major failure in the disposition of the logicians who have followed on from Frege, principally through their attachment to mathematics, and their subsequent neglect of natural language, and its basic grammar. Thus these logicians as a whole have confused, in substantial ways, categories like use with mention, identity with equivalence, predicates with functions, predicates with their nominalisations, sentences with nominals, sentences with propositions, propositions with functions, propositions with sets, properties with states of affairs, direct speech with indirect speech, reference with description, objects with facts, pronouns with nouns, mereological sums with (mathematical) sets, numbers with sets, count terms with mass terms, amounts with numbers, and also units of measure with objects, amongst other things. The book consists in fourteen chapters, with eleven of them being as they have been, or will be, when published in central journals, and other collections. Two further chapters extend the work in another two published papers, while one chapter is quite new. The chapter titles are: ‘Logic and Grammar’, ‘Completing Russell’s Logic’, ‘Logic and Arithmetic’, ‘Natural Language Sets’, ‘Namely Riders: an Update’, ‘Concept and Object in Frege’, ‘Frege’s Hidden Assumption’, ‘A Poor Concept Script’, ‘Motivation by De Se Beliefs’, ‘Out of the Liar Tangle’, ‘Ramseying Liars’, ‘Proving that 2+3=5′, ‘Harmonising Natural Deduction’, and ‘Dialetheias are Mental Confusions’.

Equivariant Degree Theory

Equivariant Degree Theory



This book presents a new degree theory for maps which commute with a group of symmetries. This degree is no longer a single integer but an element of the group of equivariant homotopy classes of maps between two spheres and depends on the orbit types of the spaces. The authors develop completely the theory and applications of this degree in a self-contained presentation starting with only elementary facts. The first chapter explains the basic tools of representation theory, homotopy theory and differential equations needed in the text. Then the degree is defined and its main abstract properties are derived. The next part is devoted to the study of equivariant homotopy groups of spheres and to the classification of equivariant maps in the case of abelian actions. These groups are explicitely computed and the effects of symmetry breaking, products and composition are thorougly studied. The last part deals with computations of the equivariant index of an isolated orbit and of an isolated loop of stationary points. Here differential equations in a variety of situations are considered: symmetry breaking, forcing, period doubling, twisted orbits, first integrals, gradients etc. Periodic solutions of Hamiltonian systems, in particular spring-pendulum systems, are studied as well as Hopf bifurcation for all these situations.

The Book of PF

The Book of PF



OpenBSD’s stateful packet filter, PF, offers an amazing feature set and support across the major BSD platforms. Like most firewall software though, unlocking PF’s full potential takes a good teacher. Peter N.M. Hansteen’s PF website and conference tutorials have helped thousands of users build the networks they need using PF. The Book of PF is the product of Hansteen’s knowledge and experience, teaching good practices as well as bare facts and software options. Throughout the book, Hansteen emphasizes the importance of staying in control by having a written network specification, using macros to make rule sets more readable, and performing rigid testing when loading in new rules.
