Bright Peaks, Dark Shadows 20 February 2012, by Jason Major
Bright peaks, dark shadows 20 February 2012, by Jason Major Amaral's "blue" peaks seen in a color-enhanced global image acquired Jan. 14, 2008. Its central peaks also attracted astronomers' MESSENGER image of Mercury's Amaral crater interest, as they were seen to possess a striking blue hue in color-enhanced images that likely indicates rocks with different composition from the surrounding surface. The 68-mile (109-km) -wide Amaral crater on Mercury reveals its brightly-tipped central peaks in Amaral's peaks resemble those of the slightly larger this image, acquired by NASA's MESSENGER crater Eminescu, which is now known to contain spacecraft on Feb. 4, 2012. Long shadows are recently-discovered features called hollows. It's not cast by the crater's peaks and rugged rim (north is yet known if Amaral also contains hollows, but it's to the left.) suspected that they may be present on the tips of the peaks.

Evidence for Thermal-Stress-Induced Rockfalls on Mars Impact Crater Slopes

The presence of these Thermal stress tracks shows that these rocks have fallen relatively recently because aeolian processes are known to infill Ices topographic lows over time. Mapping of rockfall tracks indicate trends in frequency with orientation, which in Solar radiation � � turn depend on the latitudinal position of the crater. Craters in the equatorial belt (between 15 N and 15 S) Weathering exhibit higher frequencies of rockfall on their north-south oriented slopes compared to their east-west ones. � Craters >15 N/S have notably higher frequencies on their equator-facing slopes as opposed to the other ori entations. We computed solar radiation on the surface of crater slopes to compare insolation patterns with the spatial distribution of rockfalls, and found statistically significant correlations between maximum diurnal inso lation and rockfall frequency. -

Confinement of Fermions in Tachyon Matter at Finite Temperature Adamu Issifu,1, ∗ Julio C.M. Rocha,1, y and Francisco A. Brito1, 2, z 1Departamento de F´ısica, Universidade Federal da Para´ıba, Caixa Postal 5008, 58051-970 Jo~aoPessoa, Para´ıba, Brazil 2Departamento de F´ısica, Universidade Federal de Campina Grande Caixa Postal 10071, 58429-900 Campina Grande, Para´ıba, Brazil We study a phenomenological model that mimics the characteristics of QCD theory at finite temperature. The model involves fermions coupled with a modified Abelian gauge field in a tachyon matter. It reproduces some important QCD features such as, confinement, deconfinement, chiral symmetry and quark-gluon-plasma (QGP) phase transitions. The study may shed light on both light and heavy quark potentials and their string tensions. Flux-tube and Cornell potentials are developed depending on the regime under consideration. Other confining properties such as scalar glueball mass, gluon mass, glueball-meson mixing states, gluon and chiral condensates are exploited as well. The study is focused on two possible regimes, the ultraviolet (UV) and the infrared (IR) regimes. I. INTRODUCTION Confinement of heavy quark states QQ¯ is an important subject in both theoretical and experimental study of high temperature QCD matter and quark-gluon-plasma phase (QGP) [1]. The production of heavy quarkonia such as the fundamental state ofcc ¯ in the Relativistic Heavy Iron Collider (RHIC) [2] and the Large Hadron Collider (LHC) [3] provides basics for the study of QGP. Lattice QCD simulations of quarkonium at finite temperature indicates that J= may persists even at T = 1:5Tc [4] i.e. -

People Power: the Everyday Politics of Democratic Resistance in Burma and the Philippines
People Power: The Everyday Politics of Democratic Resistance in Burma and the Philippines Nicholas Henry A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy in International Relations Victoria University of Wellington 2011 ii ... the tale he had to tell could not be one of a final victory. It could be only the record of what had had to be done, and what assuredly would have to be done again in the never ending fight against terror and its relentless onslaughts, despite their personal afflictions, by all who, while unable to be saints but refusing to bow down to pestilences, strive their utmost to be healers. Albert Camus, The Plague This thesis is dedicated to all those who, resisting the terror of state violence, continue to do what has to be done. iii Abstract How do Community Based Organisations (CBOs) in Burma and the Philippines participate in the construction of political legitimacy through their engagement in local and international politics? What can this tell us about the agency of non-state actors in international relations? This thesis explores the practices of non-state actors engaged in political resistance in Burma and the Philippines. The everyday dynamics of political legitimacy are examined in relation to popular consent, political violence, and the influence of international actors and norms. The empirical research in this thesis is based on a grounded theory analysis of in-depth semi-structured interviews with a wide cross-section of spokespeople and activists of opposition groups from Burma, and with spokespeople of opposition groups in the Philippines. -
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. -

Apollonian Circle Packings: Dynamics and Number Theory
APOLLONIAN CIRCLE PACKINGS: DYNAMICS AND NUMBER THEORY HEE OH Abstract. We give an overview of various counting problems for Apol- lonian circle packings, which turn out to be related to problems in dy- namics and number theory for thin groups. This survey article is an expanded version of my lecture notes prepared for the 13th Takagi lec- tures given at RIMS, Kyoto in the fall of 2013. Contents 1.

Integral Apollonian circle packings 15 5. Expanders and Sieve 19 References 25 1. Counting problems for Apollonian circle packings An Apollonian circle packing is one of the most of beautiful circle packings whose construction can be described in a very simple manner based on an old theorem of Apollonius of Perga: Theorem 1.1 (Apollonius of Perga, 262-190 BC). Given 3 mutually tangent circles in the plane, there exist exactly two circles tangent to all three. Figure 1. Pictorial proof of the Apollonius theorem 1 2 HEE OH Figure 2. Possible configurations of four mutually tangent circles Proof. We give a modern proof, using the linear fractional transformations ^ of PSL2(C) on the extended complex plane C = C [ f1g, known as M¨obius transformations: a b az + b (z) = ; c d cz + d where a; b; c; d 2 C with ad − bc = 1 and z 2 C [ f1g. As is well known, a M¨obiustransformation maps circles in C^ to circles in C^, preserving angles between them.
