Counterexamples to Rational Dilation on Symmetric Multiply Connected Domains
We show that if R is a compact domain in the complex plane with two or more
holes and an anticonformal involution onto itself (or equivalently a
hyperelliptic Schottky double), then there is an operator T which has R as a
spectral set, but does not dilate to a normal operator with spectrum on the
boundary of R.Comment: Post-refereed versio
Brotherton Collection MS 501 : a Middle English anthology reconsidered
Brotherton Collection MS 501, in Leeds University Library, is a fifteenth-century
anthology of Middle English religious verse and prose, best known for the Prick of
Conscience with which it begins. It received its first proper description in 1952,'
and it has recently been described in detail by Ralph Hanna (1982) and N. R. Ker
(1983).2 Nevertheless the published descriptions are unsatisfactory in one way or
another, and the manuscript's special character has not been brought out

Auguste Comte: An Intellectual Biography
On November 17, 2010 Mary Pickering spoke in the University Scholar Series hosted by Provost Gerry Selter at the Dr. Martin Luther King, Jr. Library. Mary Pickering discussed her three-volume Pulitzer Prize nominated work entitled Auguste Comte: An Intellectual Biography. Comte was a French Philosopher and the father of sociology. Professor Pickering teaches courses at SJSU in French history, German history, European women\u27s history, and urban history.https://scholarworks.sjsu.edu/uss/1005/thumbnail.jp
Analogue to Digital and Digital to Analogue Converters (ADCs and DACs): A Review Update
This is a review paper updated from that presented for CAS 2004. Essentially,
since then, commercial components have continued to extend their performance
boundaries but the basic building blocks and the techniques for choosing the
best device and implementing it in a design have not changed. Analogue to
digital and digital to analogue converters are crucial components in the
continued drive to replace analogue circuitry with more controllable and less
costly digital processing. This paper discusses the technologies available to
perform in the likely measurement and control applications that arise within
accelerators. It covers much of the terminology and 'specmanship' together with
an application-oriented analysis of the realisable performance of the various
types. Finally, some hints and warnings on system integration problems are
given.Comment: 15 pages, contribution to the 2014 CAS - CERN Accelerator School:

Determinism in the mountains: The ongoing belief in the bellicosity of 'mountain people'
It has long been argued that mountains have an effect on wars. While some research understands this chiefly in physical terms, other research looks at the effect that mountains have on human nature. This article looks at the two thousand year history of the term 'mountain people.' It explores how the belief has emerged that living in mountainous regions changes people to the degree that it makes them more likely to engage in conflict. It also explores how mountain people can be seen in a more positive light, but this perspective is often ignored by both popular media and conflict research. It makes the case that the foundations upon which perceptions of 'mountain people' are based are rather shaky and somewhat misleading for empirical conflict research
âWaiting for Chronicâ: Time, cannabis and counterculture in Hawaiâi
What does it mean not to wait? It is possible to live in ways which do not entail waiting? Through close examination of time and its articulations among a group of US 1960s-generation âhippiesâ and younger âdrop outsâ in a rural backwater of Hawaiâi, I argue in this paper that it is possible to live without waiting. Drawing on Beckettâs Waiting for Godot (1953) and Baba Ram Dassâ countercultural invocation to âremember, be here nowâ, I explore unexpected interruptions to anticipated temporal flows. Structured around three vignettes on failing to hitchhike, learning to do ethnographic fieldwork through stopping trying to do ethnographic fieldwork and an unexpected interruption in the supermarket, this paper builds up a picture of non-waiting in action. Located against a backdrop of waiting as temporal interruption and affective mode, I argue that this group sought to collectively disrupt the affective modes of indifference and/or frustration they grew up with in urban mainland America. Through new forms of affective engagement they became able to collectively reframe temporal interruption as existing within rather than without local temporal flows, interruptions ceased to be ruptures to temporal textures but part of their very fabric. Located within temporal flows, they did not force individuals out of a moral community of (time is money) efficient, productive citizens but reframed productivity itself in terms of producing sociality, positive affective experience and communitas. Out of a multitude of moments of not waiting, a temporal texture of American counterculture emerges
Some new methods for planetary exploration
For many centuries the planets of our solar system have been objects of study by astronomers. Before the invention of the telescope, these studies were restricted to an attempt to understand and predict their motion. Telescopes and accurate clocks allowed more precise observations to be made. By the 19th century, minor perturbations of the motions of the planets were being analyzed. By the end of this century, however, astronomers were becoming more interested in stellar and galactic problems, and the group interested in celestial mechanics and planetary observations appeared to be decreasing to a vanishing point in the mid-20th century. Then came the space program, and the possibility of performing experiments on, or at least near, other planets encouraged interest in the solar system to a remarkable degree
