description: Bibliography: p. 166-176
description: As glaciers retreat world-wide and ice-related geomorphological features disappear in response to climate change, the importance of understanding the repercussions of their melt on the hydrology and geomorphology of Arctic basins increases. This thesis focuses on the conceptual and numerical modelling of Fountain Glacier proglacial icing located on Bylot Island, Nunavut. Emphasis is given to the understanding of the mechanisms involved in its annual regeneration and the glaciological and hydro-physical conditions responsible for its perennial preservation. Although it is known that glacial icings strongly interact with and depend on their adjacent glacier, there is still a lack of understanding concerning temporal relationships, hydrological feeding mechanisms and the glaciological conditions involved in their perennial preservation. The study of air photos, satellite imagery, topographical and geophysical surveys, ice coring and time lapse photogrammetry allowed a comprehensive understanding of the icing's hydrology and geomorphology, and their relationships with the glacier. Results suggest that there is a strong temporal relationship between Fountain Glacier and its proglacial icing. Glacial retreat has triggered important changes in the hydro-physical conditions of the proglacial valley and the icing. These have mainly resulted in thinning of the icing and relocation of the pro glacial springs through which the icing is fed by deep englacial and subglacial water. The morphology and hydraulics of the subglacial environment were also studied. Results point out that Fountain Glacier presents a well developed subglacial hydraulic network that allows the storage and effective conduction of water used in the regeneration of the icing. Evidence showed that the glacier has a favourable thermal regime which does not only allow the storage of pressurized water, but also its efficient conduction towards the outwash plain. Finally, the hydro-physical conditions of the proglacial valley and the icing were studied. Results show that the combination of an underlying buried body of glacier ice, surrounded by a proglacial talik, allows the flow of water from the deep englacial and subglacial environment onto the outwash plain, despite the Arctic winter and the frozen glacial margins. Additionally, it is suggested that the preservation of the icing depends on the balance between three systems; glacier, permafrost and proglacial valley. Currently, they present an unstable equilibrium, where changes in the behaviour of any of the components, specially the glacier, will bring important variations to the conditions of the 1cmg.

description: The board of directors plays a central role in the corporate governance system. All countries require that publicly listed companies have a board. While their attributes vary across nations, they universally share common responsibilities. This Quick Guide provides an introduction to the roles and responsibilities of the board of directors. It answers the questions: What is the purpose of a board? How does a board function? What does it mean to be “independent”? What are the legal and fiduciary requirements?

description: We discuss a marginal deformation of the SL(2,R) x SU(2) x U(1)^4 WZW model, which describes string theory on AdS_3 x S^3 x T^4, that corresponds to warping the S^3 factor. This deformation breaks part of the N=(4,4) supersymmetry of the undeformed dual CFT to N=(0,4) supersymmetry. In the spirit of work by Giveon, Kutasov, and Seiberg, we construct the asymptotic spacetime symmetry algebra from worldsheet operators and find a restoration of (4,4) supersymmetry at discrete values of the deformation parameter. We explain this result from various perspectives: the worldsheet, supergravity, and from the singular D1-D5 CFT. The supergravity analysis includes an asymptotic symmetry computation of the level of the affine SU(2) R-symmetry, which arises purely from B-field contributions.

description: Twenty-five years ago the world entered a new era. The Soviet Union had just collapsed, the United States had assumed the leadership of a proclaimed new world order, and liberal democratic capitalism no longer had a viable global challenger. The expectations these changes heralded now appear unfulfilled. Illiberalism is surging around the world, and the post-Cold War era is rapidly giving way to a post-liberal order. Moreover, the very post-Communist states that seemingly were at the epicenter of a liberal transformation have pioneered the counter-norms and tactics that now spread to the West itself.

description: Recent literature suggests that urban coyotes may have higher infection prevalence than rural inhabitants (Bradley and Altizer, 2006). This study was a comparative investiga­tion of differences in coyote gastrointestinal parasite prevalence, intensity, and diversity between urban and rural areas of Calgary, Alberta. Weekly sampling for coyote feces was conducted over one year along transects in independent urban and rural sites. 460 samples were analysed using common fecal flotation techniques. At least fifteen parasite species were recovered. No significant differences in species prevalence existed between ur­ban and rural areas, though some significant differences were identified seasonally among urban and rural sites. Toxascaris leonina had the highest prevalence and intensity in all sites. Parasite species richness was significantly higher in rural areas, while diversity was similar. Differences in parasite prevalence, intensity, diversity, and zoonotic potential were identified among individual sites. Zoonotic risks posed were low. Overall, the simi­lar parasitism patterns suggest presence of environmental reservoirs or range expansion of coyotes among sites.

description: Street vice (anonymous prostitution, gambling, and the sale of illicit drugs) is spatially concentrated, confined largely to black neighborhoods in central cities, even though demand is quite evenly distributed throughout the general population. We show how this pattern can arise through the interacting location decisions of sellers, buyers, and non-user households. Areas with high demand density (cities) have lower prices and more tightly packed sellers in equilibrium relative to areas with lower demand density (suburbs) under autarky. When trade between city and suburb is possible, competitive pressure from the city lowers suburban prices and seller density. Higher income households distance themselves from street vice, causing the exposed population to become poorer and disproportionately black. Even mild preferences over neighborhood racial composition can then induce lower income whites to exit, resulting in racial segregation. The relationship between segregation and exposure to vice can be non-monotonic and discontinuous: decreased segregation implies greater sorting by income, and hence larger wage disparities between city and suburb. If such disparities get too large, all sales can shift discontinuously to the city and result in higher overall black exposure even though more blacks now reside in the suburbs.

description: The ultimate solution for effective diagnosis and treatment of lung diseases is the research and development of a computer-based system, which automatically converts a stack of two-dimensional (2D) computed tomographic images of lungs into a three-dimensional (3D) visualization. Current segmentation systems are unsuitable for clinical use due to one or more of the following constraints: (1) lack of automation, (2) inability to deal with multiple lung diseases and (3) incompleteness of the segmentation in the 3D space. The objective of this thesis is to research and develop a prototype for 3D segmentation and visualization of diseased lung lobes that simultaneously addresses the above three constraints. The prototype employs novel methods of texture analysis, fissure region analysis and surface modeling based on ridge regression to segment diseased lung lobes. Combined with a custom developed application programming interface in the 3D visualization software Amira, the prototype automatically converts a stack of 2D CT images into a 3D visualization of lungs with a few clicks. Tested on CT image stacks from 24 patients with a variety of lung diseases (emphysema, small cell lung cancer, large cell lung cancer, and bronchiectasis), the system produced root-mean squared errors of 2.21 ± 1.21 mm, 2.51 ± 1.36 mm, and 2.38 ± 1.27 mm in segmenting the left oblique, right oblique and right horizontal fissures, respectively ( compared to manual segmentation of the same fissures). These results indicate the feasibility of developing a clinical system for 3D segmentation and visualization of diseased lung lobes.

 Synonymie. — Libellula. T. de Charpentier.  1825. Sous-genre epitheca . Id. MSS.
 Caractères. — Tète comme dans le genre Libellule, mais sur la tempe, en arrière de chaque oe il, on remarque un prolongement, ou second oeil à facettes, séparé du grand oeil par un petit sillon qui offre une dent.
 Abdomen à peu près triangulaire, un peu déprimé, finissant en pointe, de la longueur de l’aile inférieure. Les appendices anals au nombre de trois chez le mâle, l’inférieur manquant chez la femelle; les supérieurs forts, ayant presque la longueur des deux derniers segments de l’abdomen dans les deux sexes; l’inférieur du mâle large. Les parties génitales accessoires du mâle très-proéminentes au-dessous du deuxième segment. Le bord postérieur du huitième segment de la femelle, où se trouve la vulve, prolongé en deux appendices membraneux, sessiles. Jambes allongées.
 Ailes comme dans le genre L ibellula; mais la membranule accessoire très-grande, prolongée jusqu’à l’angle anal, qui est moins arrondi que dans le G. Libellula. (Voir à l’Appendice la note sur le triangle discoïda! de l’aile.)
 Je me suis vu forcé de créer ce genre, après avoir adopté celui de Cordulia de Leach, pour classer convenablement la Libellula bimaculata de Toussaint de Chapentier, qui a les parties génitales et les appendices anals conformés à peu près comme ceux des Cordulia, taudis que le système de coloration non métallique du corps et la forme arrondie du bord interne des secondes ailes, dans les deux sexes, la rapprochent en apparence des vraies Libellules, notamment de la Quadrimaculata, seule espèce dont le mâle ressemble à la femelle et ne change pas selon l’âge, ce qui a lieu aussi dans la Libella bimaculata; mais l’organisation de ces deux espèces est tout à fait différente. Les Libella offrent, comme les Cor - dulia, ce prolongement, ou second oeil postérieur, qui n’existe pas chez les Libellules.
 Plusieurs espèces exotiques semblent devoir entrer dans ce groupe. Celle d’Europe, par sa taille et ses ailes richement colorées, est un des plus beaux insectes de cette famille.

Inertial Frame Independent Forcing for Discrete Velocity Boltzmann Equation: Implications for Filtered Turbulence Simulation

description: We present a systematic derivation of a model based on the central moment lattice Boltzmann equation that rigorously maintains Galilean invariance of forces to simulate inertial frame independent flow fields. In this regard, the central moments, i.e. moments shifted by the local fluid velocity, of the discrete source terms of the lattice Boltzmann equation are obtained by matching those of the continuous full Boltzmann equation of various orders. This results in an exact hierarchical identity between the central moments of the source terms of a given order and the components of the central moments of the distribution functions and sources of lower orders. The corresponding source terms in velocity space are then obtained from an exact inverse transformation due to a suitable choice of orthogonal basis for moments. Furthermore, such a central moment based kinetic model is further extended by incorporating reduced compressibility effects to represent incompressible flow. Moreover, the description and simulation of fluid turbulence for full or any subset of scales or their averaged behavior should remain independent of any inertial frame of reference. Thus, based on the above formulation, a new approach in lattice Boltzmann framework to incorporate turbulence models for simulation of Galilean invariant statistical averaged or filtered turbulent fluid motion is discussed.

description: Randall Sundrum models provide a possible explanation of (gauge-gravity) hierarchy, whereas discrete symmetry flavor groups yield a possible description of the texture of Standard Model fermion masses. We use both these ingredients to propose a five-dimensional extension of the Standard Model where the mass hierarchy of the four-dimensional effective field theory is obtained only using localizations parameters of order 1. We consider a bulk custodial gauge symmetry group together with an Abelian $Z_4$ group: the model turns out to yield a rather minimal extension of the SM as it only requires two brane Higgs fields to provide the desired Yukawa interactions and the required spontaneous symmetry breaking pattern. In fact, the presence of an extra-dimension allows the use of the Scherk-Schwarz mechanism to contribute to the breaking of the bulk custodial group down to the SM gauge symmetry. Moreover, no right-handed neutrinos are present and neutrino masses are generated radiatively with the help of a bulk charged scalar field that provides the Lepton-number violation. Using experimental inputs from the Global Neutrino Analysis and recent Daya Bay results, a numerical analysis is performed and allowed parameter regions are displayed.

description: One of the many exciting revelations of the New Horizons flyby of Pluto was the observation of global haze layers at altitudes as high as 200 km in the visible wavelengths. This haze is produced in the upper atmosphere through photochemical processes, similar to the processes in Titan's atmosphere. As the haze particles grow in size and descend to the lower atmosphere, they coagulate and interact with the gases in the atmosphere through condensation and sticking processes that serve as temporary and permanent loss processes. New Horizons observations confirm studies of Titan haze analogs suggesting that photochemically produced haze particles harden as they grow in size. We outline in this chapter what is known about the photochemical processes that lead to haze production and outline feedback processes resulting from the presence of haze in the atmosphere, connect this to the evolution of Pluto's atmosphere, and discuss open questions that need to be addressed in future work.

description: This paper presents a simplified method for furrow irrigation system design for clay soils in arid regions. Field experiments were conducted for a furrow irrigations system at an experimental site in Egypt with clay soils, cultivated with cotton and irrigated by a three-turn crop rotation. Several parameters were measured including the furrow geometry, slope, furrow width, furrow length, infiltration characteristics, advance time, cut-off time, depletion time, and recession time. A volume balance model was applied to simulate water flow in the furrow system and the results were compared to those obtained from the field measurements. This study shows that a volume balance model can be satisfactorily applied to clay soils and the length of the furrow and its inlet discharge are the main factors affecting application efficiency. Also, this study indicates that in order to obtain high application efficiencies, one must use low discharge rates for small furrows and as the furrow length increases the discharge must also increase, and that furrow length can be increased with higher soil moisture contents.

description: Robbery is a serious, widespread and sometimes violent crime resulting each year in costs to victims of several billion dollars. Data on the incidence of robbery reveals certain striking racial disparities. African Americans are more likely to be victims, arrestees and prisoners than are members of other demographic groups, and while black-on-white robberies are very common, white-on-black robberies are extremely rare. The disparities for robbery are also much greater than those for other crimes of acquisition. We develop a model of robbery that attempts to address these and other stylized facts. The key insight underlying the model is that robberies are typically interactions between strangers which involve a sequence of rapid decisions with severely limited information. Potential offenders must assess the likelihood of victim resistance, and victims must assess the likelihood that resistance will be met with violence. Racial disparities in the distribution of income can cause such probability assessments to be race-contingent, affecting crime rates as well as rates of resistance and violence. We argue that this model helps account for several empirical regularities that appear puzzling from the perspective of alternative theories of crime.

description: We present a method to quantify the spin Hall angle (SHA) with spin pumping and microwave photoresistance measurements. With this method, we separate the inverse spin Hall effect (ISHE) from other unwanted effects for permalloy/Pt bilayers using out-of-plane microwave excitation. Through microwave photoresistance measurements, the in- and out-of-plane precessing angles of the magnetization are determined and enabled for the exact determination of the injected pure spin current. This method is demonstrated with an almost perfect Lorentz line-shape for the obtained ISHE signal and the frequency independent SHA value as predicted by theory. By varying the Pt thickness, the SHA and spin-diffusion length of Pt is quantified as 0.012 (0.001) and 8.3 (0.9) nm, respectively.

description: Scientific views on human variation and the relationship between humans and apes changed dramatically between 1700-1900. This paper traces the history of those changes from an initial consensus on the homogeneity of man and on casual models tied to environmental contrasts to the turn of the 20th century when "race was everything". Over the course of these two centuries new sciences were born and matured and vast quantities of data were collected, generated and digested. Yet, paradoxically, while the overwhelming majority of data indicated that discrete interpopulational contrasts among humans were elusive, the broader social constructs, likely among them economics, would rely on a scientific foundation that viewed the differences as innate and fixed. By the turn of the twentieth century Europeans and European-Americans would explain their economic and military superiority in biological terms, even if contradicted by the data. Through an analysis of changing perspectives on the key underlying constructs of essentialism, fixity and ranking, we try to understand these shifting views on the nature of human variation.

In this paper, we calculate AC Stark shift due to lattice trapping laser which dominates the frequency shift of clock transition in lattice trapped Rubidium four-level active optical clock. Several magic wavelengths are found that can form desired optical lattice trapping potential. By choosing a proper intensity and linewidth of trapping laser, the fractional frequency uncertainty of clock transition due to AC Stark shift of trapping laser, is estimated to be below 10^-18

Panorama ultrasound for navigation and guidance of epidural anesthesia
Creators: name: Rafii-Tari, Hedyeh
Publisher: name: University of British Columbia
Year: 2011

description: Epidural anesthesia is a common but challenging procedure in obstetrics and surgery, especially for the obese patient, and can result in complications such as dural puncture and nerve injury. Ultrasound has the potential to significantly improve epidural needle guidance, by being able to depict the spinal anatomy and the epidural space. An ultrasound guidance system is therefore proposed, using a transducer-mounted camera to create 3D panorama images of the spine relative to markings on the skin. Guidance will include depiction of the spinal anatomy, identification of individual vertebrae, and selection of a suitable puncture site, trajectory and depth of needle insertion. The camera tracks the transducer movement using a specialized strip of markers attached to the skin surface. This enables 6-DOF absolute position estimation of the transducer with respect to the patient over the full range of the spine. The 3D panorama image can then be resliced in various parasagittal planes to show either the target epidural spaces or the laminae. The overall accuracy of the panorama reconstruction is validated by measuring inter-feature distances of a phantom of steel beads against measurements obtained from an optical tracking system (Optotrak), resulting in an average error of 0.64 mm between camera and Optotrak. The algorithm is then tested in vivo by creating panorama images from human subjects (n=20), obtaining measurements for depth of insertion to the epidural space, intervertebral spacings, and registration of interspinous gaps to the skin, and validating these against independent measurements by an experienced sonographer. The results showed an average error of 1.69 mm (4.23%) for the depth measurements, average error of 4.44 mm (15.2%) for the interspinous distance measurements, and an average error of 6.65 mm for registering the interspinous gaps to the skin (corresponding to 18.5% of the interspinous distances). Tracking of ultrasound images with respect to the marker is implemented in real time and visualized using the 3D Slicer software package.

description: Between 2000 and 2006 the murder rate in Newark doubled while the national rate remained essentially constant. Newark now has eight times as many murders per capita than the nation as a whole. Furthermore, the increase in murders came about through an increase in lethality: total gun discharges rose much more slowly than the likelihood of death per shooting. In order to explain these trends we develop a theoretical model of murder in which preemptive killing and weapon choice play a central role. Strategic complementarity amplifies changes in fundamentals, so areas with high murder rates (war zones) respond much more strongly to changes in fundamentals than those with low murder rates (peaceable kingdoms). In Newark, the changes in fundamentals that set off the spiral were a collapsing arrest rate (and probably a falling conviction rate), a reduction in prisoners, and a shrinking police force.

description: Witness intimidation is a fundamental threat to the rule of law. It also involves significant strategic complexity and two-sided uncertainty: a criminal cannot know whether his threat will effectively deter a witness from testifying, and a witness cannot know whether the threat will in fact be carried out. We model this interaction and explore the manner in which equilibrium rates of intimidation, testimony, and conviction respond to changes in prosecutorial effectiveness, police-community relations, and witness protection programs. An increase in prosecutorial effectiveness raises the incentives for criminals to threaten witnesses but also makes these threats less credible. Sometimes the rise in threats will be large enough to drive down the rate of conviction, with the paradoxical outcome that better prosecutors may convict fewer criminals. Direct attempts to reduce witness tampering may also prove counterproductive. When the harm faced by a witness itself depends on whether or not the criminal is convicted, communities can be trapped in equilibria with collective silence: no witness testifies because none expects others to testify.

description: This essay rethinks the meanings and constituents of a film archive by examining private film scrapbooks as a mode of liminal historiography. In the face of institutional disregard, the 'kinetomaniac' or the obsessive, possessive lover of the movies offers the film historian some lessons in playful and libidinal logics of archiving and interpretation.

description: We have successfully synthesized FeSe films by the electrochemical deposition in the electrolyte containing FeCl_{2}\cdot4H_{2}O, SeO_{2} and Na_{2}SO_{4}. The composition ratio of Fe and Se was controlled by the synthesis voltage and pH value. The FeSe film with the composition ratio of Fe : Se = 1 : 1 is fabricated at a voltage of -0.9 V and pH 2.1 in our electrochemical deposition. This sample has a highly crystalline tetragonal FeSe structure and exhibits a superconducting transition at 8.1 K, comparable to FeSe synthesized by other methods.

Investigation of factors affecting the performance of roadside noise barriers
Creators: name: Daltrop, Shira Nicole Jones
Publisher: name: University of British Columbia

description: Roadside noise barriers are used to prevent traffic noise from reaching nearby residences. Two factors that may affect the acoustical performance of highway noise barriers - surface absorption and nearby vegetation - were investigated. Three experimental techniques were used: full-scale laboratory tests, field tests, and scale-model tests. Tests with a 1.2m high barrier on a hard surface were performed in an anechoic chamber, using source and receiver positions corresponding to different diffraction angles. Absorption was added to the wall in various configurations and the change in insertion loss (IL) was measured. IL's of 12-18 dBA behind and -1 dBA in front of the reflective wall were found. Surface absorption increased IL by up to 2 dBA behind the barrier and 1 dBA in front. For the field tests, traffic noise was measured behind reflective noise walls without and with nearby foliage. Effects were small, less than 5 dB, but suggest that vegetation can either attenuate sound, increasing the IL, or scatter sound into the barrier shadow zone, decreasing the IL. A 1:31.5 scale-model highway configuration was created and tested in an anechoic chamber. Scale-model materials were chosen by performing excess attenuation measurements and doing a best fit using flow resistivity. Absorption was tested on single and parallel noise barriers of varying heights, allowing for a comparison between adding absorption and increasing the height. Foliage tests were performed on single and parallel barriers with various configurations of model trees. Barrier absorption prevented the amplification of sound between parallel barriers and adding absorption was equivalent to increasing the height by 0.33 m. The foliage test results were similar to the field tests; the effects were small and dependent on frequency and the size of the foliage. Predicting these results was attempted using ray tracing, the method of images (MOI), and finite element methods (FEM). An existing ray tracing model, PRAY, was modified and used; however the predicted IL’s were 10-30 dB greater than those measured. FEM gave IL's 2-8 dB lower and MOI gave IL's 5-20 dB lower than measurements.

description: The work with digital data demands some form of version control. In its simplest and still common appearance version control consists of file naming conventions, and often some creative form of duplication of files. The rising degree of collaboration in data creation and complexity of data, however, brings these basic methods to their limits, which is one of many practical and theoretical reasons why explicit and structured version control with the help of a version control system (VCS) is required. The introduction and use of a VCS for research data in the humanities faces the obstacle of a steep learning curve and poses severe problems with regard to usability, since VCS implementations mostly originate from software engineering. To deal with this problem we discuss the open source script LAMA which is used to perform operations with the VCS Git. Using LAMA does not require in-depth knowledge of the VCS or additional technical expertise, so the focus of the individual researcher can remain on the creation of the research data itself. Additional advantages include messenger integration and the option to run consistency operations with pluggable tools.

description: There has been recent progress on computing real-time equilibrium 3-point functions in finite-temperature strongly-coupled N=4 super Yang-Mills (SYM). In this paper, we show an example of how to carry out a similar analysis for a 4-point function. We look at the stopping of high-energy "jets" in such strongly-coupled plasmas and relate the question of whether, on an event-by-event basis, each jet deposits its net charge over a narrow (~ 1/T) or wide (>> 1/T) spatial region. We relate this question to the calculation of a 4-point equilibrium correlator.
