This monograph provides the first up-to-date and self-contained presentation of a recently discovered mathematical structure—the Schrödinger-Virasoro algebra. Just as Poincaré invariance or conformal (Virasoro) invariance play a key rôle in understanding, respectively, elementary particles and two-dimensional equilibrium statistical physics, this algebra of non-relativistic conformal symmetries may be expected to apply itself naturally to the study of some models of non-equilibrium statistical physics, or more specifically in the context of recent developments related to the non-relativistic AdS/CFT correspondence. The study of the structure of this infinite-dimensional Lie algebra touches upon topics as various as statistical physics, vertex algebras, Poisson geometry, integrable systems and supergeometry as well as representation theory, the cohomology of infinite-dimensional Lie algebras, and the spectral theory of Schrödinger operators.

A fresh (in more than one sense) and honest new voice in fiction is extravagantly displayed in this first novel that candidly dissects modern romance. Plagued with weird parents, an underdeveloped body, and a mind on the verge of self-deconstruction, Phoebe Fine feels ill-equipped for a journey through the hardening chambers of the late twentieth-century heart. But from fifth grade and Roger Mancuso, equal parts baby Brando and court jester, through her early adult life with New Media executive Neil Schmertz, a babytalker who prefers spooning to sex, Phoebe trudges defiantly through guyland, armed with a tart tongue, and propelled by an insatiable desire to be loved.
The first comprehensive guide to Pelléas et Mélisande, Debussy’s only completed opera, this book is written by three of the leading authorities on French music of the period. As a background to the opera Richard Langham Smith discusses the play, by the Belgian dramatist Maeterlinck, and considers its literary roots. David Grayson then traces the genesis and composition of the opera, examining also the sketches and rejected versions in order to illuminate Debussy’s compositional strategies. A detailed synopsis by Roger Nichols, which considers carefully Debussy’s musical response to the text, forms a central chapter. The book then moves on to consider more detailed aspects of the style and language of the opera. The relationship between symbols and musical motives forms the basis of a chapter by Richard Langham Smith, and a subsequent chapter by him considers the themes of darkness and light and the key-schemes used to portray them. Two chapters by Roger Nichols on the various performances since 1902 and on the ideas of interpreters and commentators complete the text. The book concludes with a detailed bibliography and a discography.
Optimal filtering applied to stationary and non-stationary signals provides the most efficient means of dealing with problems arising from the extraction of noise signals. Moreover, it is a fundamental feature in a range of applications, such as in navigation in aerospace and aeronautics, filter processing in the telecommunications industry, etc. This book provides a comprehensive overview of this area, discussing random and Gaussian vectors, outlining the results necessary for the creation of Wiener and adaptive filters used for stationary signals, as well as examining Kalman filters which are used in relation to non-stationary signals. Exercises with solutions feature in each chapter to demonstrate the practical application of these ideas using MATLAB.

Inevitably, numerous international regulations and conventions pertaining to labour and social security have followed in the wake of the onrush of economic globalization, greatly augmenting the considerable legal regime developed by the International Labour Organisation (ILO) and the United Nations (UN) during the mid and late twentieth century. This book presents as complete and up-to-date a codification as possible of international labour and social security law, with texts of the most important documents and direct reference to print and online sources of all relevant conventions, regulations, recommendations, agreements, declarations and guidelines. The codification encompasses all pertinent promulgations of the UN, the ILO, the North American Free Trade Association (NAFTA), and the Organisation for Economic Cooperation and Development (OECD).Among the texts reprinted in full are the following: The Universal Declaration of Human Rights (UN); International Convention on the Elimination of All Forms of Racial Discrimination (UN); International Covenant on Economic, Social, and Cultural Rights (UN); International Covenant on Civil and Political Rights (UN); Convention on the Elimination of All Forms of Discrimination Against Women (UN); Convention on the Rights of the Child (UN); Constitution of the ILO; ILO Conventions covering such issues as forced labour, employment of children, maternity, protection against unemployment, freedom of association and protection of the right to organise and to bargain collectively, vocational guidance and training, and employment of indigenous peoples; ILO Conventions protecting workers against such workplace hazards as ionising radiation, carcinogenic substances and agents, air pollution, noise and vibration; Declaration of Principles Concerning Multinational Enterprises (ILO); Declaration on Fundamental Principles and Rights at Work (ILO); North American Agreement on Labor Cooperation; and OECD Guidelines for Multinational Enterprises.
