The purpose of this note is to give a “coordinate free” construction and prove the uniqueness of the vertex algebroid which gives rise to the chiral de Rham complex of [GMS]. In order to do that, we adapt the strategy of [BD] to the setting of vertex agebroids. To this end we show that the stack EVAX of exact vertex algebroids on X is a torsor under the stack in Picard groupoids ECAX of exact C...

Caltech neuroscientist Paul Patterson, whose career spanned developmental neurobiology, behavioral neuroscience, and neuroimmunology, passed away on June 25 at the age of 70 from an aggressive brain tumor. Patterson was a pioneer and an iconoclast who was not afraid to work outside of the scientific mainstream; consequently, he made a number of important and seminal contributions that opened up...

Central bank talk has been a topic of debate and empirical analysis within the central bank community and the economics profession for at least the thirty years that span Chuck’s career as a central banker. And what many regard as the seminal work in this area has a particularly Canadian connection. The work on bureaucratic theory and the choice of central bank goals by Acheson and Chant (1973)...

In the spring of 1965, Dr. Beeson decided to leave the chairmanship of Internal Medicine at Yale for the Nuffield Chair in Internal Medicine at Oxford. With this decision he brought to an end a fruitful and exciting period in the development of the Yale Medical School. In recognition of his contributions to the institution in which he played so important a part, the editors of the YALE JOURNAL ...

Introduction Imaging genetics is a rapidly emerging field that is opening up a new landscape of discovery in medicine and neuroscience. The field is a hybrid effort that merges methods anddiscoveries in both imaging and genetics; its power has recently taken a quantum leap for a number of reasons. First, many groups worldwide are scanning thousands of individuals with structural and functional ...

came in 1985 when he, Andrej Joachimiak, and others Paul Sigler, who died in January of a cardiac arrest while published the structure of the dimeric trp repressor of walking to work, embarked on protein crystallography E. coli. Comparisons of the structures of the repressor only two years after the first two structures had been with and without tryptophan and of the tryptophansolved, when it w...

In the following, S is a finite set but later we’ll deal with infinite sets. Think of S as the set of “outcomes” of some “experiment.” The outcomes are elementary indivisible results of the experiment; we’ll make this more precise through examples below. The set S must be nonempty. Let S 6= ∅ be a finite set. A function P which maps the subsets of S to real numbers will be called probability pr...

This document describes a framework for preparing Unicode text strings in order to increase the likelihood that string input and string comparison work in ways that make sense for typical users throughout the world. The stringprep protocol is useful for protocol identifier values, company and personal names, internationalized domain names, and other text strings. This document does not specify ...
