Placing World War I in the History of Mathematics David Aubin and Catherine Goldstein Abstract. In the historical literature, opposite conclusions were drawn about the impact of the First World War on mathematics. In this chapter, the case is made that the war was an important event for the history of mathematics. We show that although mathematicians' experience of the war was extremely varied, its impact was decisive on the life of a great number of them. We present an overview of some uses of mathematics in war and of the development of mathematics during the war. We conclude by arguing that the war also was a crucial factor in the institutional modernization of mathematics. Les vrais adversaires, dans la guerre d'aujourd'hui, ce sont les professeurs de math´ematiques`aleur table, les physiciens et les chimistes dans leur laboratoire. -
Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

Lähdekirjallisuudesta kerättyä tietoa käsiteltiin tutkielman teoriaosuudessa, minkä jälkeen empiirinen osuus selvitti, kuinka kyseisiä menetelmiä sovelletaan käytännössä nykyenglannissa. Tämän selvittämiseksi käytiin manuaalisesti läpi korpusaineisto, joka koostui isobritannialaisen Total Film -elokuvalehden yhden vuoden aikana julkaistuista numeroista. Elokuvajournalismissa käytettävä kieli valittiin tutkimuksen kohteeksi kirjoittajan henkilökohtaisen kiinnostuksen vuoksi sekä siksi, että elokuva on paitsi merkittävä, myös jatkuvasti kehittyvä taiteen ja populaarikulttuurin muoto. Niinpä tämän tutkielman tarkoitus on myös tutustuttaa lukija sellaiseen sanastoon, jota alaa käsittelevä lehdistö nykypäivänä Isossa-Britanniassa käyttää.

SCREENING RACE ALEXANDRA MCCALLA The “hood” spaces of South Central in Los Angeles and — North Kensington in West London—known as Grove, Boyz n the Hood (1991) short for the area’s main road Ladbroke Grove—both Kidulthood (2006) experienced an influx of black migrant workers in the first half of the 20th century. The films Boyz n the Hood (1991) and Kidulthood (2006) explore the current problems of the South Central and Grove hoods respectively, while presenting the effects of the historical construction of these spaces. Both are written and directed by black men, set and shot in the areas in which they grew up, John Singleton’s Boyz n the Hood (Boyz) and Noel Clarke’s Kidulthood intimately reveal the nuances of their hoods. Through analysing the two hood films’ depiction of race and space, the socio-economic effects on race relations in London and LA can be examined. The “Great Migration” in the US, out of the South from 1910-1930, due to obtainable wealth in factory jobs, caused a shift in the African American identity; black people were not simply associated with the South’s con- 4 notations of slavery.

Discrete Element Modelling of Pit Crater Formation on Mars
geosciences Article Discrete Element Modelling of Pit Crater Formation on Mars Stuart Hardy 1,2 1 ICREA (Institució Catalana de Recerca i Estudis Avançats), Passeig Lluís Companys 23, 08010 Barcelona, Spain; [email protected]; Tel.: +34-934-02-13-76 2 Departament de Dinàmica de la Terra i de l’Oceà, Facultat de Ciències de la Terra, Universitat de Barcelona, C/Martí i Franqués s/n, 08028 Barcelona, Spain Abstract: Pit craters are now recognised as being an important part of the surface morphology and structure of many planetary bodies, and are particularly remarkable on Mars. They are thought to arise from the drainage or collapse of a relatively weak surficial material into an open (or widening) void in a much stronger material below. These craters have a very distinctive expression, often presenting funnel-, cone-, or bowl-shaped geometries. Analogue models of pit crater formation produce pits that typically have steep, nearly conical cross sections, but only show the surface expression of their initiation and evolution. Numerical modelling studies of pit crater formation are limited and have produced some interesting, but nonetheless puzzling, results. Presented here is a high-resolution, 2D discrete element model of weak cover (regolith) collapse into either a static or a widening underlying void. Frictional and frictional-cohesive discrete elements are used to represent a range of probable cover rheologies. Under Martian gravitational conditions, frictional-cohesive and frictional materials both produce cone- and bowl-shaped pit craters. For a given cover thickness, the specific crater shape depends on the amount of underlying void space created for drainage. -

Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971.

The Very Forward CASTOR Calorimeter of the CMS Experiment
EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH (CERN) CERN-EP-2020-180 2021/02/11 CMS-PRF-18-002 The very forward CASTOR calorimeter of the CMS experiment The CMS Collaboration* Abstract The physics motivation, detector design, triggers, calibration, alignment, simulation, and overall performance of the very forward CASTOR calorimeter of the CMS exper- iment are reviewed. The CASTOR Cherenkov sampling calorimeter is located very close to the LHC beam line, at a radial distance of about 1 cm from the beam pipe, and at 14.4 m from the CMS interaction point, covering the pseudorapidity range of −6.6 < h < −5.2. It was designed to withstand high ambient radiation and strong magnetic fields. The performance of the detector in measurements of forward energy density, jets, and processes characterized by rapidity gaps, is reviewed using data collected in proton and nuclear collisions at the LHC. ”Published in the Journal of Instrumentation as doi:10.1088/1748-0221/16/02/P02010.” arXiv:2011.01185v2 [physics.ins-det] 10 Feb 2021 © 2021 CERN for the benefit of the CMS Collaboration.

Edwards University of Western Ontario Abstract No abstract provided. Keywords African-American cinema, Hughes Brothers, Allen Hughes, Albert Hughes, hood film Recommended Citation Edwards, Timothy J. (2011) "Realer than Reel: Menace II Society and the 1990’s Hood Film Cycle," Kino: The Western Undergraduate Journal of Film Studies: Vol. 2 : Iss. 1 , Article 3. Edwards: Realer than Real Realer than Reel: Menace II Society and the 1990s Hood Film Cycle by Timothy J. Edwards The convergence of numerous industrial and social factors in the late 1960s saw Hollywood studios for the first time invest in films produced with African-Americans as the target audience. This wave of Black-focused product eventually became known as ‘Blaxploitation’ Cinema. Blaxploitation films use cinematic devices like: location shooting, hand held camera, and sync-sound along with a showcasing of distinctly Black cultural imagery, featuring urban fashion, slang, Black nationalist politics, and of course Black popular music to create a Black ghetto chronotope which is common to all Blaxploitation films (Massood 117). While the Black ghetto chronotope has its roots in Blaxploitation, it has since become an important tool which New Black Cinema directors like the Hughes brothers further develop to depict the streets of Watts with a sharp and uncompromising sense of realism. Allen and Albert Hughes spoke of being “outraged by the Hollywood sentimentality” of the hugely successful Boyz n the Hood (1991), which was released two years before Menace II Society (1993) (Massood 162).
