My introduction to copulas - An interview with Roger Nelsen
No full textRoger Nelsen is Professor Emeritus of Mathematics at Lewis & Clark College in Portland, Oregon, USA. He studied mathematics at DePauw University (BA, 1964) and Duke University (PhD, 1969). Roger joined the faculty at Lewis & Clark in the fall of 1969, and retired in 2009. Prior to Lewis &
Clark, Roger spent a year with the Biostatistics Unit of the Centre International de Recherche sur le Cancer in Lyon, France. He has had visiting appointments at the University of Massachusetts in Amherst and Mount Holyoke College in South Hadley, Massachusetts. In addition to his monograph
"An Introduction to Copulas", Roger has authored or co-authored eleven books published by the Mathematical Association of America. He has served on the editorial boards of two MAA journals and several of their book series.
The fifth interview of this series features a conversation with Roger Nelsen. His Springer book An Introduction
to Copulas is eponymous for a mathematical precise and well written entrance into the fascinating field of copulas. Moreover, it serves as a classical reference book, a large number of citations bear witness to this. He collaborated with seminal researchers in our field, and kindly shares his view and memories with us. Roger’s second strand of research – a combination of mathematical puzzles, art, and visualization – are “Proofs Without Words.” He published several books, containing elegant visual justifications of mathematical
statements. In the following, our questions to Roger Nelsen are typeset in bold-face
All the mighty world: The photographs of Roger Fenton, 1852–1860
No full textRoger Fenton was the most significant photographer of the mid-19th century whose work covered a wide range of genres, though perhaps best regarded for his photographic studies of the Crimean War in 1855. As the principal curators of the exhibition were American I was asked to join the team because of my specialist knowledge of Fenton, photographic exhibitions and the culture of Victorian Britain. Working with the notes prepared by Baldwin of the Getty, I prepared a detailed and footnoted chronology, researching into many new aspects of Fenton’s life using the local history archives in Lancashire, London and other primary sources. The resulting chronology was circulated to the authors as an aide-memoir for their essay writing. It is the only chronology in the field to benefit from footnotes. My two essays relied extensively on primary source material. In the Royal Archives, Windsor I was granted generous access to the photographic collections, archives and Royal Library. The extensive research into 19th century photographic exhibitions I undertook when preparing Photographs Exhibited in Britain (PEIB) allowed me to offer the first detailed account of Fenton’s exhibiting activities. The PEIB website was used by every author, making it the most frequently cited work in the exhibition catalogue.
A website was created to present faithful transcriptions of the letters sent by Fenton to his family during his time in the Crimea tour. Other than a poorly transcribed and willfully edited publication of letters from 1954 this important collection remained largely unknown. It was a collaborative project that drew of the manuscript collections of the University of Texas at Austin and the National Media Museum, Bradford.

Equivariant homology for SL(2) of a p-adic field
No full textLet F be a p-adic field and let G = SL(2) be the group of unimodular 2 × 2 matrices over F. The aim of this paper is to calculate certain equivariant homology groups attached to the action of G on its tree. They arise in connection with a theorem of M. Pimsner on the K-theory of the C∗-algebra of G [12], and our purpose is to explore the representation theoretic content of Pimsner’s result. The outcomes of our calculations are given in Theorems 5.4 and 6.1. In Sections 8 and 9 of the paper we re-examine Pimsner’s theorem in the light of these new results. The first author and A. Connes have formulated a very general conjecture [1] describing the K-theory of the reduced C∗-algebra of any locally compact group. For a semisimple group over a p-adic field it asserts, roughly speaking, that the cohomology of the space of tempered representations of G is isomorphic to the equivariant homology of the affine Bruhat-Tits building of G. For SL(2) and other split rank one groups the conjecture amounts to Pimsner’s theorem, but for groups of higher rank the conjecture is not yet proved. In a sequel to this article we shall study the representation theoretic aspects of the conjecture for p-adic groups (we note that the arguments in Sections 5 and 8 readily extend to this general case). Our homology groups are very closely related to the cyclic homology groups of the convolution algebra of smooth compactly supported functions on G, and the results of our calculations are similar to some of P. Blanc and J-L. Brylinski in [3]. But the methods we employ are different, and we hope they complement rather than duplicate those of Blanc and Brylinski. The connection between the two will be explored elsewher
The tumble mode - where test pilots fear to tread
No full textFollowing a fatal accident in 1997 and identification of common patterns in several (usually fatal) previous accidents the AAIB (United Kingdom Air Accidents Investigation Branch) asked the BMAA (British Microlight Aircraft Association) to pursue a course of investigation into the tumble mode, which had been attributed as the primary cause of that fatal accident.
The tumble mode is a peculiarity of weightshift controlled aircraft - that is flexwing microlights and hang-gliders. It is a departure from controlled flight leading to a nose-down pitch autorotation: pitch rates of 400°/s are known. When a tumble occurs in a microlight aeroplane, it is rare for the crew to survive and loss of the aircraft is universal
Design and synthesis of G-quadruplex selective macrocyclic polyoxazoles
No full textNucleic acid sequences that can form stable G-quadruplex structures have been implicated in numerous biological functions. G-quadruplexes are thought to play a vital role in telomere maintenance and regulating gene expression. The majority of cancer cells over-express telomerase, an enzyme that bypasses the aging process by adding telomeric repeats to chromosome ends. Also about 65% of oncogenes have a potential G-quadruplex forming sequence in their promoter region. It is believed that stabilized G-quadruplexes can indirectly inhibit telomerase and decrease oncogene expression resulting in cancer cell death. These observations have led to the development of small molecules that stabilize G-quadruplexes as a new class of anticancer agents. Several research groups have developed such molecules but most lack selectivity over other forms of DNA. A unique molecule among these is telomestatin, a macrocyclic natural product with 70-fold selectivity for G-quadruplex DNA over duplex and low micromolar cytotoxicity. Although telomestatin has exceptional activity, it is difficult to synthesize and hard to formulate because it lacks water-solubilizing groups. Initial studies utilized telomestatin as a lead structure to develop a novel class of macrocyclic hexaoxazoles with the most active compound being HXDV. It was shown to stabilize G-quadruplex DNA with no detectable interaction with duplex DNA and had comparable cytotoxic activity to telomestatin. Unfortunately, HXDV had limited aqueous solubility and required a lengthy synthesis. Efforts to modify the structure of HXDV to enhance water solubility and simplify the synthetic process are described in this dissertation. While this was generally successful, a shorter synthesis was needed to rapidly assess structure-activity relationships. This led to the development of a second class of compounds called macrocyclic pyridyl polyoxazoles (PyPX). These compounds utilize a molecular scaffold that is readily accessed in few synthetic steps to form numerous macrocyclic analogs. This enables quick assessment of structure-activity relationships. Several members of this class are excellent G-quadruplex stabilizers and do not interact with duplex DNA. These compounds also possess low nanomolar cytotoxicity and one was active in an in vivo bioassay. Structure-activity studies utilizing the PyPX scaffold continue in an effort to identify clinical candidates.Ph.D.Includes bibliographical referencesIncludes vitaby Suzanne G. Rzucze
