This monograph gives a comprehensive treatment of spectral (linear) stability of weakly relativistic solitary waves in the nonlinear Dirac equation. It turns out that the instability is not an intrinsic property of the Dirac equation that is only resolved in the framework of the second quantization with the Dirac sea hypothesis. Whereas general results about the Dirac-Maxwell and similar equations are not yet available, we can consider the Dirac equation with scalar self-interaction, the model first introduced in 1938. In this book we show that in particular cases solitary waves in this model may be spectrally stable (no linear instability). This result is the first step towards proving asymptotic stability of solitary waves. The book presents the necessary overview of the functional analysis, spectral theory, and the existence and linear stability of solitary waves of the nonlinear Schrödinger equation. It also presents the necessary tools such as the limiting absorption principle and the Carleman estimates in the form applicable to the Dirac operator, and proves the general form of the Dirac-Pauli theorem. All of these results are used to prove the spectral stability of weakly relativistic solitary wave solutions of the nonlinear Dirac equation.

A personal and cultural exploration of silence and its value in our lives—“[an] artful book, mixing autobiography, travel writing, meditation, and essay” (Independent, UK). In her late forties, after a noisy upbringing as one of six children and adulthood as a vocal feminist and mother, Sara Maitland found herself living alone in the country and, to her surprise, falling in love with silence. In this fascinating, intelligent, and beautifully written book, Maitland describes how she began to explore this new love, spending periods of silence in the Sinai desert, the Scottish hills, and a remote cottage on the Isle of Skye. Maitland also delves deep into the rich cultural history of silence, exploring its significance in fairy tale and myth, its importance to the Western and Eastern religious traditions, and its use in psychoanalysis and artistic expression. Her story culminates in her building a hermitage on an isolated moor in Galloway. “Her book is probably unique in its subject, and timely, because good, healing silence is becoming hard to find, and we may not know we need it” (Guardian, UK).

An eye-opening short book by the international bestselling writer of Born on a Blue Day and Thinking in Numbers. Have you ever wondered how neurotypicals - so called 'normal' people - come across to those who are on the autistic spectrum? What would an instruction manual about being an average human being look like to them? And actually, would it be that different, fundamentally, to a field guide about autistic people (were such a thing to exist)? Daniel Tammet is an essayist, poet, novelist and translator. In 2004, he was diagnosed with high-functioning autistic savant syndrome. In this eye-opening and fascinating book, he takes readers on a tour around nightclubs, ponders the significance of tattoos, delves into anti-age creams and puzzles over playing the lottery, all from the perspective of someone who approaches everything in life from a unique angle. After all, this is a man for whom Wednesdays are always blue, who sees numbers as shapes and who learned conversational Icelandic from scratch in seven days. These short essays come together in a beautifully written, sometimes humorous but always refreshing narrative that focuses on the eccentricities of modern life as seen through the eyes of someone always on the outside. Rather wonderfully, it illustrates the eccentricity inherent in every kind of mind, reminding us of the little-noticed strangeness of our common humanity, while subtly questioning what it means to be thought 'normal'.

During the past decade a significant international research effort has been directed towards understanding the composition and regulation of the preocular tear film. This effort has been motivated by the recognition that the tear film plays an essential role in maintaining corneal and conjunctival integrity, protecting against microbial challenge and preserving visual acuity. In addition, research has been stimulated by the knowledge that alteration or deficiency of the tear film, which occurs in countless individuals throughout the world, may lead to desiccation of the ocular surface, ulceration and perforation of the cornea, an increased incidence of infectious disease, and potentially, pronounced visual disability and blindness. 7 To promote further progress in this field of vision research, the International Conference on the Lacrimal Gland, Tear Film and Dry Eye Syndromes: Basic Science and Clinical Relevance was held in the Southampton Princess Resort in Bermuda from November 14 to 17, 1992. This meeting was designed to assess critically the current knowledge and 'state of the art' research on the structure and function of lacrimal tissue and tears in both health and disease. The goal of this conference was to provide an international exchange of information that would be of value to basic scientists involved in eye research, to physicians in the ophthalmological community, and to pharmaceutical companies with an interest in the treatment of lacrimal gland, tear film or ocular surface disorders (e. g. Sjogren's syndrome).
