Veneration of the saints is one of the defining characteristics of early medieval society and culture. This important book by a group of distinguished experts adopts for the first time an interdisciplinary approach to examine the innumerable local cults which developed in western Europe between about 400 and 1000, concentrating especially on Celtic and Anglo-Saxon saints. The volume combines wide-ranging surveys with crucial reference material, including a handlist of all known Anglo-Saxon saints.

The seminal 1970 Moscow thesis of Grigoriy A. Margulis, published for the first time. Entitled "On Some Aspects of the Theory of Anosov Systems", it uses ergodic theoretic techniques to study the distribution of periodic orbits of Anosov flows. The thesis introduces the "Margulis measure" and uses it to obtain a precise asymptotic formula for counting periodic orbits. This has an immediate application to counting closed geodesics on negatively curved manifolds. The thesis also contains asymptotic formulas for the number of lattice points on universal coverings  of compact manifolds of negative curvature. The thesis is complemented by a survey by Richard Sharp, discussing more recent developments in the theory of periodic orbits for hyperbolic flows, including the results obtained in the light of Dolgopyat's breakthroughs on bounding transfer operators and rates of mixing.

There is considerable interest in thermophile microorganisms, in their environments, their ability to survive at temperatures which normally denature proteins, but more importantly, as a valuable resource for bio technology. The first reported isolation of Thermus by Tom Brock was in 1969. This initiated the present era of thermophilic research with the realization that where liquid water is available, there may be no limits to the temper ature at which microorganisms can grow. Considerable research into the ecology, physiology, metabolism, and thermostable enzymes of thermo philes has led to their evaluation for a range of industrial and commercial processes. The past fifteen years have been an explosive period of dis covery of many new genera and species, including the descriptions of a new fundamental kingdom-the Archaea. Much of the current research has been focused on the Archaea; but it is significant that during this period, the original type strain YT-l of Thermus aquaticus described by Brock has provided a major step forward in molecular biology. DNA polymerase from strain YT-I has proved to be the major success in the commercialization of enzymes from thermophilic microorganisms to date. The ease with which Thermus strains can be handled in laboratories without specialized equipment, together with the large investment in de scribing their structure, metabolism, and genetics, should ensure a con tinuing effort in Thermus research.

In the mid 1960s, when a single chip contained an average of 50 transistors, Gordon Moore observed that integrated circuits were doubling in complexity every year. In an in?uential article published by Electronics Magazine in 1965, Moore predicted that this trend would continue for the next 10 years. Despite being criticized for its unrealistic optimism, Moore s prediction has remained valid for far longer than even he imagined: today, chips built using state-- the-art techniques typically contain several million transistors. The advances in fabrication technology that have supported Moore s law for four decades have fuelled the computer revolution. However, this exponential increase in transistor density poses new design challenges to engineers and computer scientists alike. New techniques for managing complexity must be developed if circuits are to take full advantage of the vast numbers of transistors available. In this monograph we investigate both (i) the design of high-level languages for hardware description, and (ii) techniques involved in translating these hi- level languages to silicon. We propose SAFL, a ?rst-order functional language designedspeci?callyforbehavioralhardwaredescription, anddescribetheimp- mentation of its associated silicon compiler. We show that the high-level pr- erties of SAFL allow one to exploit program analyses and optimizations that are not employed in existing synthesis systems. Furthermore, since SAFL fully abstracts the low-leveldetails of the implementation technology, we show how it can be compiled to a range of di?erent design styles including fully synchronous design and globally asynchronous locally synchronous (GALS) circuits."

This is a study of three important late medieval collections of saints' Lives. The manuscripts, written in Latin and, for the most part, relating to the lives of Irish saints, have never before been subject to critical examination. Richard Sharpe's pioneering analysis addresses such questions as when and where the Lives were compiled, and from what sources they derive. Dr Sharpe sets his own treatment of the collections within the wider context of Irish hagiographical studies. Formidable research underpins his lucid exposition and resolution of complex problems of historical and linguistic evidence.

Although related to one of the ruling families of Ireland, Columba (c 521-97) became a central figure in the 'Age of Saints' by setting out from his native land and founding his famous monastery on the island of Iona.

It was from here that priests and monks played a key role in converting the Picts of Scotland, here that countless penitents came on pilgrimages and that the King of Dalriada (Argyll) came to be consecrated. Adomnán's Life, writes Richard Sharpe, is the fullest early account, offering a 'vivid depiction of the abbot among his own monks, written on the spot by the saint's successor one hundred years after Columba's death'.

Drawing on extensive written and oral traditions, Adomnán presents Columba as a man distinguished for his prophetic and miraculous powers, whose life was filled with angelic apparitions and whose dying days were spent preparing for his departure. A stimulating Introduction sketches in the background, the archaeological evidence from Iona and the legends that grew up around Columba in medieval and more recent times. The result is an ideal new edition, equally suitable for readers seeking spiritual insight or the hard core of historical fact.

Medieval England was full of books, many times the number that have survived. The great moment of loss was when the country’s religious houses were suppressed by King Henry VIII and their libraries scattered and destroyed. Twentieth-century scholarship has been enterprising in establishing what survives and in discovering what libraries once held. To understand that evidence, and to be able to reconstruct the transmission of culture in the Middle Ages, we need to employ with care the evidence of the surviving books and what medieval library catalogues can tell us about these lost collections. Libraries and Books in Medieval England paints a new picture of the circulation of books, from the totality of the available evidence. It seeks to move away from the modern conceptualization of the monastic library as the only venue for medieval book provision, and to broaden awareness of the wider book economy, including private ownership and the birth of the book trade. The result, by one of the country’s leading experts and based on his Lyell Lectures in the University of Oxford, is an unparalleled work offering a new view of the field.
