description: We study the transformation under the String Theory duality group of the observable charges (mass, angular momentum, NUT charge, electric, magnetic and different scalar charges) of four dimensional point-like objects whose asymptotic behavior constitutes a subclass closed under duality. The charges fall into two complex four-dimensional representations of the duality group. T duality (including Buscher's) has an O(1,2) action on them and S duality a U(1) action. The generalized Bogomol'nyi bound is an U(2,2)-invariant built out of one representations while the other representation (which includes the angular momentum) never appears in it. The bound is manifestly duality-invariant. Consistency between T duality and supersymmetry requires that primary scalar hair is included in the Bogomol'nyi bound. Four-dimensional supersymmetric massless black holes are the T duals in time of massive supersymmetric black holes. Non-extreme massless ``black holes'' are the T duals of the non-extreme black holes and have primary scalar hair and naked singularities.

Seals, Identity and Patronage in the Ancient Near East (ca. 1550-1050 BC)

description: Numerous art historians and anthropologists such as Rudolf Wittkower, Michael Baxandal and Alfred Gell have addressed the question of how art reflected the people by and for whom it was produced in the context of different cultures and periods. In my dissertation, I intend to contribute to this discussion through a study of two hundred and sixteen Mesopotamian and Syrian seals and seal impressions. Made of a variety of precious and semi-precious materials such as stones or metals, and carved with detailed designs and pictorial images, seals are some of the most distinctive types of ancient Near Eastern art, and were widely diffused in the society. The seals studied in this dissertation originally belonged to the individuals, from royalty to special cooks, representing different segments of the society, and are dated to the second half of the second millennium BC. I carried out a detailed analysis of the material, inscriptions, images on these objects and their context of use. This analysis shows that the seals that belonged to royal and non-royal individuals such as princes, priests/priestesses, scribes, doctors, singers, tax collectors and other temple and state officials may indicative of certain aspects of their owners' identity such as social class, profession and gender. Additionally, most of these seals were not mass-produced, but unique items created according to the choices of individual patrons. However, it was still possible to recognize the works of different craftsmen especially in the seals from Babylonia and Assyria through their distinctive styles. In this sense, Near Eastern seals were complex works of art in which the stylistic inputs of craftsmen were fused with the iconographic and compositional choices of the patrons, who commissioned them. These different choices, in return, might have signified the social class, gender, professional affiliation, and even political ambitions of the ancient seal owners.

description: Regioselective synthesis of three novel palmitates of 20(R)-ginsenoside Rg3 was accomplished via a facile strategy, along with complete assignment of their 1H and 13C NMR resonances by 1D and 2D NMR (1H-1H COSY, DEPT 135, HSQC, HMBC, and NOESY) techniques. The derivatives were tested for in vitro anti-proliferative activities against pancreatic cancer PANC-1 cells. Compounds 2, 3, and 4 exhibited more potent activity than did 20(R)-ginsenoside Rg3.

r-Matrix for the restricted KdV Flows with the Neumann constraints
Creators: name: Zhou, Ruguang
Publisher: name: arXiv
Year: 1998
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: Under the Neumann constraints, each equation of the KdV hierarchy is decomposed into two finite dimensional systems, including the well-known Neumann model. Like in the case of the Bargmann constraint, the explicit Lax representations are deduced from the adjoint representation of the auxiliary spectral problem. It is shown that the Lax operator satisfies the r-matrix relation in the Dirac bracket. Thus, the integrabilities of these resulting systems with the Neumann constraints are obtained.

description: Two dimensional semiconductors provide an ideal platform for exploration of linear exciton and polariton physics, primarily due to large exciton binding energy and strong light-matter coupling. These features, however, generically imply reduced exciton-exciton interactions, hindering the realisation of active optical devices such as lasers or parametric oscillators. Here, we show that electrical injection of itinerant electrons into monolayer molybdenum diselenide allows us to overcome this limitation: dynamical screening of exciton-polaritons by electrons leads to the formation of new quasi-particles termed polaron-polaritons that exhibit unexpectedly strong interactions as well as optical amplification by Bose-enhanced polaron-electron scattering. To measure the nonlinear optical response, we carry out time-resolved pump-probe measurements and observe polaron-polariton interaction enhancement by a factor of 50 ($0.5 μ$eV $μ$m$^2$) as compared to exciton-polaritons. Concurrently, we measure a spectrally integrated transmission gain of the probe field of $\gtrsim 2$ stemming from stimulated scattering of polaron-polaritons. We show theoretically that the non-equilibrium nature of optically excited quasiparticles favours a previously unexplored interaction mechanism stemming from a phase-space filling in the screening cloud, which provides an accurate explanation of the strong repulsive interactions observed experimentally. Our findings show that itinerant electron-exciton interactions provide an invaluable tool for electronic manipulation of optical properties, demonstrate a new mechanism for dramatically enhancing polariton-polariton interactions, and pave the way for realisation of nonequilibrium polariton condensates.

Planning, construction and operational challenges of Suncor’s 1st sand dump
Creators: name: Ali, Zulfiqar
Publisher: name: The University of British Columbia
Year: 2011

description: In 2009, Suncor Energy Inc.’s Oil Sands operation in Fort McMurray, AB, began the process of changing to a new technology for the treatment of the tailings streams coming from their water-based extraction process. This new treatment, known collectively as Tailings Reduction Operations (TRO™), is based on two primary technologies: Mature fine tailings (MFT) drying, and the construction of elevated and draining sand dumps. Most of the public information on TRO™ has been focused on the MFT drying components, with less attention paid to the technically simpler but operationally complex systems required to build stacks of tailings sand contained within sand dykes at the rates required to sustain production. This paper discusses the planning and operational challenges of constructing the sand dump rising at the rate of 20 meters per year while maintaining continuous oil sands production and structural integrity of the dump. [All papers were considered for technical and language appropriateness by the organizing committee.]

description: We investigate the superconducting mechanism and the transition temperature of heav y fermion superconductor UPd_2Al_3 on the basis of a single band two-dimensional Hubbard model on triangular lattice, whi ch represents the most heavy band of UPd_2Al_3. Both normal and anomalous self-energies are calculated up to third order with respect to the Coulomb repulsion U between itinerant electrons. The superconducting transition temperature is obtained by solving the Eliashberg's equation. Reasonable transition temperatures are obtained for moderately large U. It is fou nd that the momentum and frequency dependence of spin fluctuations given by RPA-like terms gives rise to the d-wave pairing state, while the vertex correction terms are important for obtaining reasonable transition tempe ratures. These results seem to show that the superconductivity in UPd_2Al_3 can be explained by the perturbation theory with respect to U.

Sculpture, Slavery, and Commerce in the Nineteenth-Century Atlantic World

Slavery in art
Sculpture

description: This dissertation investigates the intersection of nineteenth-century figurative sculpture with an American slave economy whose impact reverberated across time and transnational geographies. Scholars have long acknowledged how sculptural depictions of the enslaved body by Hiram Powers, John Bell, and Francesco Pezzicar played vital roles in dialogues about abolition and Emancipation on both sides of the Atlantic. Yet renewed examination of individual works of art, the terms of their circulation and display, and the markets and regimes of racialized value they occupied suggests that the production and consumption of these statues also unfolded in physical and conceptual proximity with systems of commerce and commodification formed under slavery. Working at the intersection of material culture studies, critical race theory, and legal and literary studies, this study conceives of sculpture as a transactional object that inhabited an interconnected world of art and commerce spanning merchants’ exchanges and cotton factorage houses in the American South, industrial manufacturing firms in Britain, sculptors’ studios and art academies in Italy, World’s Fairs, and private homes. Following an introductory discussion of the entanglement of art and the economy of slavery in nineteenth-century Atlantic spaces writ large, chapters examine the traveling exhibition of Hiram Powers’ Greek Slave in antebellum New Orleans, the manufacture and display of John Bell’s statues depicting enslaved black and mixed- race women in the abolitionist British Atlantic, and the circulation of Francesco Pezzicar’s sculptural commemoration of American slavery between post-Civil War Philadelphia and Risorgimento Italy. From these case studies it is argued that sculpture stood as a highly visible but deeply unstable site from which to interrogate the politics of slavery, on one hand because of the medium’s entanglement with trade and commerce, and on the other because of its relationship to considerations of the corporeal. Nineteenth-century concerns with the animacy of sculpture – long understood as measures of artistic virtuosity in making a statue appear as if it were living – were inextricable from the hierarchies of race and subjectivity that shaped the institution of slavery and its structures of bodily commodification. In raising questions about the motivation and management of subjects and objects in slavery’s wake, this study complicates discussions about the status of the object in art history and criticism while contributing to broader interdisciplinary dialogues concerning race, representation, and the body.

De nos jours, les téléphones intelligents ont changé notre façon de communiquer en utilisant tantôt la communication orale, tantôt les messages écrits ou les images, i.e. les émojis. Par le biais d’une méthodologie quantitative, en l’occurrence un sondage électronique suivi des quelques questions ouvertes, la présente thèse de maîtrise se penche sur le rôle et l’impact des émojis dans la réception de messages texte. Afin de procurer un nouveau regard sur l’influence des émojis dans la communication iconique, nous avons mesuré le confort des participants vis-à-vis six mises en situation provenant de contextes amoureux, amical et professionnel. Nos résultats indiquent que les émojis peuvent influencer la perception des messages texte et que le contexte de la communication joue un rôle important dans l’acceptabilité de ces images numériques.

description: This thesis contains two stand-alone articles for which the overall purpose is to learn from the experiences of a non-Indigenous SFD program designed for Indigenous youth, by exploring how the program has dealt with questions of Indigenous knowledge, culture, and worldviews. By looking at how the program officers and managers articulate their experiences and challenges within the different phases of designing, managing and implementing the SFD program, this study examines questions of decolonization, Indigenization, and resurgence. The first article utilizes an Indigenous resurgence lens to explore the challenges of running the Promoting Life Skills in Aboriginal Youth (PLAY) program through the reflective discourses of middle-upper level management staff members. The main objectives of the first article are to 1) explore the perception of the PLAY staff on challenges experienced within program design and development generally, 2) analyze those challenges in light of critical research on SFD, and 3) inform program development with Indigenous youth. In the second article, I examine the experiences and perceptions of the staff and in dealing more specifically with the question of culture and Indigenous knowledge and Indigenization. This article highlights the experiences that occurred during a two-year period of Indigenous leadership, two years after the piloting of the program. The objectives of this article are to 1) consider and examine the place of culture within SFD for Indigenous youth 2) highlight and learn from Indigenous leadership experience in a Western-based program 3) inform program development.

description: A search for displaced photons from exotic decays of the Higgs boson is presented, specifically targeting the relatively weak constraints on the branching ratio of Higgs boson decays to invisible particles imposed by other searches. 139 fb⁻¹ of 𝑝-𝑝 collision data at center-of-mass energy √𝑠 = 13 TeV, collected between 2015 and 2018, is analyzed. Exploiting the excellent timing performance and longitudinal segmentation of the ATLAS electromagnetic calorimeter, the photon arrival time and extrapolation to the beam axis, or pointing, can be used to extract the displaced photon signature from Standard Model background processes. The background photon timing and pointing distributions are predicted using carefully constructed, data-derived templates. Signal contributions are analyzed in the context of a Gauge-Mediated Supersymmetry Breaking model in which the Higgs boson decays into two, long-lived next-to-lightest supersymmetric particle neutralinos, which each subsequently decay into a photon and a gravitino. Agreement with background is observed with no significant excesses for any signal models considered. Limits at the 95% confidence level are placed on the branching ratio of the Higgs boson to two neutralinos in the context of the various signal models.

Search for Heavy Down-Type Vector-Like Quarks in the Lepton-Plus-Jets Final State in 8 TeV proton-proton Collisions Using the ATLAS Detector at the LHC
Creators: Hu, Diedi
Publisher: name: Columbia University
Year: 2015
Subjects: Physics

description: This dissertation presents a search for pair production of heavy down-type vector-like quarks (VLQ B) using the full 2012 data set of proton-proton collisions at the center of mass 8 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider, corresponding to an integrated luminosity of 20.3 1/fb. Events with a single charged lepton, which can be either an electron or muon, missing transverse energy, at least six jets, at least one tagged as a b-jet, and at least one reconstructed hadronically-decaying W/Z boson candidate are analyzed. No significant deviation from the Standard Model background prediction is observed. Under the assumption that only the B->Wt/Zb/Hb decay modes are allowed, 95% CL upper limits are derived in the two dimensional plane of the B->Wt branching ratio versus B->Hb branching ratio. In the specific case where the branching ratios are consistent with a SU(2) singlet scenario, the observed (expected) 95% CL lower limit on the VLQ B mass is 640 GeV (505 GeV). In the chiral B scenario with a 100% branching ratio of the decay B->Wt, the observed (expected) 95% CL lower limit on the B mass is 814 GeV (756 GeV).

description: This dissertation describes a search for resonant WW and WZ production in the lvjj decay channel using 4.701 fb-1 of sqrt(s) = 7 TeV LHC collision data collected by the ATLAS detector. Events with a single charged lepton, at least two jets and missing transverse energy are analyzed and no significant deviation from the Standard Model prediction is observed. Upper limits on the production cross section are interpreted as lower limits on the mass of a resonance and are derived assuming two warped extra-dimension production modes: the original Randall-Sundrum (RS1) model and the more recent "bulk" Randal-Sundrum (Bulk RS) model. The mass range for both models is excluded at 95% CL with a lower mass limit for an RS1 graviton of 936 GeV and 714 GeV for the Bulk RS graviton.

description: Text removal algorithms have been proposed for uni-lingual scripts with regular shapes and layouts. However, to the best of our knowledge, a generic text removal method which is able to remove all or user-specified text regions regardless of font, script, language or shape is not available. Developing such a generic text eraser for real scenes is a challenging task, since it inherits all the challenges of multi-lingual and curved text detection and inpainting. To fill this gap, we propose a mask-based text removal network (MTRNet). MTRNet is a conditional adversarial generative network (cGAN) with an auxiliary mask. The introduced auxiliary mask not only makes the cGAN a generic text eraser, but also enables stable training and early convergence on a challenging large-scale synthetic dataset, initially proposed for text detection in real scenes. What's more, MTRNet achieves state-of-the-art results on several real-world datasets including ICDAR 2013, ICDAR 2017 MLT, and CTW1500, without being explicitly trained on this data, outperforming previous state-of-the-art methods trained directly on these datasets.

description: Основой статьи послужили результаты мониторингового исследования, проведенного в Республике Татарстан в 2018 г. в рамках реализации проекта федеральной инновационной площадки Министерства просвещения Российской Федерации «Учитель 2.0». Данные по возрасту, уровню образования, квалификационной категории и месту работы позволили создать среднестатистический портрет современного молодого педагога общеобразовательной организации. Результаты исследования показывают осознанность выбора профессии и интересы педагогов в учебной и внеучебной деятельности, не всегда совпадающие с видом актуальной занятости. Основные методические затруднения педагогов связаны с ведением документации, проведением урока по современным требованиям и взаимодействием с обучающимися и их родителями. Современным молодым педагогам для продуктивной работы не хватает, в первую очередь, времени и опыта, а также умения планировать свою деятельность и распределять ресурсы. Кроме того, затронута проблема наставничества как ключевого фактора адаптации, развития и преодоления выявленных затруднений молодых специалистов. Чтение серьезной профессиональной литературы и конкретные запросы в образовательных мероприятиях показывают степень заинтересованности учителей в саморазвитии. Молодые педагоги уже не считают традиционные долгосрочные курсы повышения квалификации приоритетным способом профессионального развития, уделяя больше внимания более коротким и насыщенным образовательным мероприятиям, таким как семинар и конкурс, потому что они направлены на обретение определенных практических навыков. Тематика этих запросов, а также приоритетные направления развития и краткосрочные перспективы, выделенные самими молодыми педагогами, стали ориентирами при составлении плана мероприятий по реализации федерального инновационного проекта. В статье представлены рекомендации для закрепления, успешной адаптации, самореализации и профессионального развития молодых учителей в образовательных организациях.

description: We find strong numerical evidence for a new phenomenon in a binary black hole spacetime, namely the merger of marginally outer trapped surfaces (MOTSs). By simulating the head-on collision of two non-spinning unequal mass black holes, we observe that the MOTS associated with the final black hole merges with the two initially disjoint surfaces corresponding to the two initial black holes. This yields a connected sequence of MOTSs interpolating between the initial and final state all the way through the non-linear binary black hole merger process. In addition, we show the existence of a MOTS with self-intersections formed immediately after the merger. This scenario now allows us to track physical quantities (such as mass, angular momentum, higher multipoles, and fluxes) across the merger, which can be potentially compared with the gravitational wave signal in the wave-zone, and with observations by gravitational wave detectors. This also suggests a possibility of proving the Penrose inequality mathematically for generic astrophysical binary back hole configurations.

description: Brandenberger and Vafa have proposed the string cosmological model based on T-duality. In this model, they took the toroidal target space and introduced the new position \tilde{x} conjugate to the winding mode, in addition to the position x conjugate to the momentum mode. In this way they can describe a universe larger than the string scale with the coordinate x and one smaller with the coordinate \tilde{x}. Resultingly, they never encounter the singularity seen in the standard Big Bang scenario. The most interesting phenomenon in this model is the transition from \tilde{x}-space to x-space when the size of universe is nearly the string scale. Here, we define the dispersion of the momentum number m times the winding number w as the `correlation' of momentum modes and winding modes. Then using the statistical mechanics of strings on a torus, we calculate the correlation in low and high temperature limits, and we consider the possibility that we can observe this effect today, but we will see that this is unlikely.

Search for gravitons using merged jets from Z boson decays with the ATLAS experiment
Creators: Penson, Alexander Vincent
Publisher: name: Columbia University
Year: 2012
Subjects: Physics

description: A search is presented for anomalous production of a pair of gauge bosons (ZZ or WZ) from the decay of a narrow massive resonance. Data corresponding to 2.0 fb-1 of integrated luminosity collected by the ATLAS experiment from proton-proton collisions at 7 TeV. Events with two charged leptons and either two resolved jets or one merged jet are analyzed and found to be consistent with the Standard Model background expectation. In the absence of an excess, lower limits on the mass of a resonance are set using the original Randall-Sundrum (RS1) model as a benchmark. The observed (expected) lower limit on the mass of an excited graviton decaying to ZZ is 870 (950) GeV at 95% confidence level. Limits are also set on a more recent version of the Randall-Sundrum model where Standard Model particles are allowed to propagate in the five dimensional bulk. An excited graviton in this model is excluded for masses between 500 and 630 GeV.

description: Let K be a knot in the 3-sphere with 2-fold branched covering space M. If for some prime p congruent to 3 mod 4 the p-torsion in the first homology of M is cyclic with odd exponent, then K is of infinite order in the knot concordance group. As one application, recall that the n-twisted double of an arbitrary knot has order 4 in Levine's algebraic concordance group if and only if n is positive and some prime congruent to 3 mod 4 has odd exponent in 4n+1; we show that all such knots are of infinite order in the knot concordance group. As a second application, the 2-bridge knot K(r,s) has infinite order in the knot concordance group if some prime congruent to 3 mod 4 has odd exponent in r.

Search for R-parity violating supersymmetry in multilepton final states using the ATLAS detector

description: This thesis presents a search for R-parity violating supersymmetry at sqrt(s)=13 TeV, using approximately 13.3 fb-1 of data collected by ATLAS in 2015 and the first half of 2016. Events are required to contain at least four leptons (electrons or muons only) that are not the product of a Z boson decay, and this requirement results in a low Standard Model background and a high sensitivity to various physics models beyond the Standard Model. No significant deviations from the Standard Model are observed in data, and results are used to set upper limits on the event yields from processes beyond the Standard Model. In a simplified model of chargino production with indirect R-parity violating decays, limits are extended by approximately 400 GeV relative to the Run 1 search, excluding chargino masses below 1.1 TeV.

Search for Non-Pointing Photons in the Diphoton and Missing Transverse Energy Final State in 7 TeV pp Collisions Using the ATLAS Detector

Publisher: name: Columbia University
Year: 2014
Subjects: Particles (Nuclear physics)

description: A search for photons originating in the decay of a neutral long-lived particle produced in proton-proton collisions at sqrt(s) = 7 TeV is presented. The search was performed in the diphoton plus missing transverse energy final state, using the full data sample of 4.8  fb-1 of 7 TeV proton-proton collisions collected in 2011 with the ATLAS detector at the CERN Large Hadron Collider.  The analysis exploits the capabilities of the ATLAS electromagnetic calorimeter to make precise measurements of the flight direction of photons, and utilizes the excellent time resolution of the calorimeter as an independent cross-check of the results. The search was conducted in the context of Gauge Mediated Supersymmetry Breaking models, where the lightest neutralino is the next-to-lightest supersymmetric particle and has a finite lifetime. In the family of models investigated, supersymmetric particles are produced in pairs due to R-parity conservation, eventually decaying to a pair of neutralinos, each subsequently decaying to a photon and a gravitino. The gravitinos escape the detector, giving rise to missing energy, while the photons can appear not to originate from the primary vertex of the event, and are measured with a delay with respect to the collision time. No excess was observed above the background expected from Standard Model processes. The results were used to set exclusion limits at 95% CL in the two-dimensional parameter space defined by the supersymmetry breaking scale and the lifetime of the lightest neutralino.

description: Considering the coupled envelope equations in nonlinear couplers, the question of integrability is attempted. It is explicitly shown that Hirota's bilinear method is one of the simple and alternative techniques to Painlevé analysis to obtain the integrability conditions of the coupled nonlinear Schrödinger (CNLS) type equations. We also show that the coupled Hirota equation introduced by Tasgal and Potasek is the next hierarchy of the inverse scattering solvable CNLS equation. The results are in agreement with the known results.

description: We consider the closed orbit structure of generic gradient flows of Morse closed 1-forms. The torsion of a chain homotopy equivalence between the Novikov complex and the completed simplicial chain complex of the universal cover detects the eta function of the flow. We extend this result to arbitrary Morse closed 1-forms. The case of rational forms was considered by A. Pajitnov.

Search for a new resonance in the boosted di-Higgs to 4 bottom quarks final state at √s = 8 TeV using the ATLAS detector at the Large Hadron Collider
Creators: Zhou, Lei
Publisher: name: Columbia University
Year: 2015
Subjects: Physics

description: This thesis presents a search for a new, heavy particle decaying to a pair of Higgs bosons in the 4 bottom quarks final state at √s= 8 TeV using the ATLAS detector at the Large Hadron Collider. The full data collected by ATLAS in 2012 at √s = 8 TeV is used, corresponding to a total luminosity of 19.5 fb -1. A novel technique, using smaller radius track jet to tag bottom quarks in combination with two large radius calorimeter jets to fully reconstruct boosted event topologies, significantly improves the sensitivity up to the mass scale of 2 TeV. In the absence of an excess, upper limits on the production cross section are set with 95% confidence level, using Kaluza-Klein gravitons in the bulk Randall-Sundrum model with coupling c ≡ k √M pl = 1.0 and 2.0 as benchmarks.
