description: We have compared the TeV gamma-rays with the new 12CO J=2-1 data toward HESS J1745-303 in the Galactic center and confirmed that the molecular gas MG358.9-0.5 toward (l, b)=(358.9, -0.5 at VLSR=-100-0 km s-1 shows a reasonable positional agreement with the primary peak (northern part) of the gamma-ray source. For the southern part of HESS J1745-303, we see no CO counterpart, whereas the HI gas in the Parkes 21 cm HI dataset shows a possible counterpart to the gamma-ray source. This HI gas may be optically thick as supported by the HI line shape similar to the optically thick 12CO. We estimate the total mass of interstellar protons including both the molecular and atomic gas to be 2x10^6 Mo and the cosmic-ray proton energy to be 6x10^{48} ergs in the hadronic scenario. We discuss possible origins of the cosmic-ray protons including the nearby SNR G359.1-0.5. The SNR may be able to explain the northern gamma-ray source but the southern source seems to be too far to be energized by the SNR. As an alternative, we argue that the second-order Fermi acceleration in the inter-clump space surrounded by randomly moving high-velocity clumps may offer a possible mechanism to accelerate protons. The large turbulent motion with velocity dispersion of ~15 km s-1 has energy density two orders of magnitude higher than in the solar vicinity and is viable as the energy source.

Total economy : the Artist Placement Group (1969-1976)
Creators: name: Jackson, Katherine
Publisher: name: University of British Columbia
Year: 2024

description: This dissertation examines the Artist Placement Group’s (APG) artist placements within industry and government in the U.K. and Western Europe from 1969-1976 and brings to light correspondence letters, corporate contracts, proposals and artist statements that have not been previously published. I consider the APG’s placements as prototypes that sought to juxtapose and critically question what they perceived as artificial divisions within society. These included art versus society, left versus right political affiliations, the working class versus management, perceptions of use versus uselessness in capitalist production and the organization versus the individual. I specifically examine Garth Evans’s placement with the British Steel Corporation (1968), Stuart Brisley’s placement with Hille & Co (1971), John Latham’s placement with the Scottish Office (1974) and the APG group exhibition titled, inn7o: Art and Economics (1972). These case studies form chapters that investigate the specific socio-political conditions of each placement’s organization, artist and the artwork produced under the umbrella of the APG mission. I adopt a localized social art history approach that considers these placements within the divisions of the British Marxist Left and the changes in the U.K.’s economic and labor policy that occurred against a backdrop of paradigm shifting events, such as the U.K.’s acceptance into the EEC (the predecessor to the EU). Within this politically sensitive and complex context, I argue that the APG’s refusal of political party and class affiliations was representative of a complete disavowal of their contemporary political options; a political position that for artistic practice meant foregoing class and political loyalties in favor of focusing on art’s relationship to ideology itself. Exploring themes of class, labor, time and the political potential of a work of art, I argue for the broader importance of the APG within histories of art and interdisciplinary practice, and propose an alternative perspective of the relationship between art and politics during the 1960s and 70s.

description: Because of an old quasar APM 08279+5255 at $z=3.91$, some dark energy models face the challenge of the cosmic age problem. It has been shown by Wei and Zhang [Phys. Rev. D {\bf 76}, 063003 (2007)] that the holographic dark energy model is also troubled with such a cosmic age problem. In order to accommodate this old quasar and solve the age problem, we propose in this Letter to consider the interacting holographic dark energy in a non-flat universe. We show that the cosmic age problem can be eliminated when the interaction and spatial curvature are both involved in the holographic dark energy model.

description: We derive the three-loop dilatation operator of the flavor SU(2) subsector of N=4 supersymmetric Yang-Mills theory in the planar limit by a direct Feynman diagram calculation in N=1 superspace. The transcendentality three contributions which appear in intermediate steps cancel among each other, leaving a rational result which confirms the predictions from integrability. We derive finiteness conditions that allow us to avoid the explicit evaluation of entire classes of Feynman graphs and also yield constraints on the D-algebra manipulations. Based on these results, we discover universal cancellation mechanisms. As a check for the consistency of our result, we verify the cancellation of all higher-order poles.

description: We use sub-parsec resolution hydrodynamic resimulations of a Milky Way (MW) like galaxy at high redshift to investigate the formation of the MW satellite galaxies. More specifically, we assess the impact of supernova feedback on the dwarf progenitors of these satellite, and the efficiency of a simple instantaneous reionisation scenario in suppressing star formation at the low-mass end of this dwarf distribution. Identifying galaxies in our high redshift simulation and tracking them to z=0 using a dark matter halo merger tree, we compare our results to present-day observations and determine the epoch at which we deem satellite galaxy formation must be completed. We find that only the low-mass end of the population of luminous subhalos of the Milky-Way like galaxy is not complete before redshift 8, and that although supernovae feedback reduces the stellar mass of the low-mass subhalos (log(M/Msolar) < 9), the number of surviving satellites around the Milky-Way like galaxy at z = 0 is the same in the run with or without supernova feedback. If a luminous halo is able to avoid accretion by the Milky-Way progenitor before redshift 3, then it is likely to survive as a MW satellite to redshift 0.

description: The behavior of the hadron scattering amplitude determined by the gravitation interaction of hadron at high energies with impact of the KK-modes in d-brane models of gravity is examined. The possible periodic structure of the scattering amplitude and its dependence on the number of additional dimensions are analyzed. The effects of the gravitational hadron form factors obtained from the hadron eneralized parton distributions (GPDs) on the behavior of the interaction potential and the scattering amplitude are analyzed. It is shown that in most part the periodic structure comes from the approximation of our calculations.

description: The Lorentz-violating isotropic modified Maxwell theory minimally coupled to standard Dirac theory is characterized by a single real dimensionless parameter which is taken to vanish for the case of the standard (Lorentz-invariant) theory. A finite domain of positive and negative values of this Lorentz-violating parameter is determined, in which microcausality and unitarity hold. The main focus of this article is on isotropic modified Maxwell theory, but similar results for two anisotropic nonbirefringent cases are presented in the appendices.

The regulation of erythroid progenitors and T cells by CD45
Creators: name: Shim, Yaein Amy
Publisher: name: University of British Columbia
Year: 2021

description: The immune system plays a crucial role in the protection of the host against infection and the maintenance of homeostasis under normal conditions. This is achieved by cooperative work amongst a diverse population of immune cells. The pan-leukocyte marker CD45 is a receptor-type tyrosine phosphatase expressed on all nucleated hematopoietic cells. While the function of CD45 on adaptive immune cells has been well described, the role of CD45 on innate immune cells and erythroid progenitors is less understood. CD71⁺TER119⁺ erythroid progenitors are prevalent in neonates; in addition to generating mature erythrocytes, they create an immunosuppressive environment. Here, I show that CD45 regulates late erythroid development as CD45-deficient mice maintained a high level of CD71⁺TER119⁺ progenitor cells in the spleen into adulthood. Despite the increase, CD45-deficient mice had normal numbers of mature red blood cells (RBCs) due to increased sensitivity of erythroid progenitors to erythropoietin (EPO) and an increased number of EPO-producing red pulp macrophages (RPMs). Increased CD71⁺TER119⁺ cells in CD45-deficient RAGKO mice (CD45RAGKO) had an impact on the outcome of T cell transfer colitis. CD45RAGKO had delayed systemic wasting and reduced TNFα production by splenic myeloid cells despite having an equal level of inflammation in the colon. Adoptive transfer of erythroid progenitors from CD45RAGKO donor into RAGKO attenuated the weight loss and reduced TNFα expression by RPMs. Co-culturing of erythroid cells suppressed TNFα expression from RPMs in a phagocytosis-dependent manner. These findings implicate CD45 as a positive regulator of systemic inflammation and suggest erythroid progenitors are an anti-inflammatory agent in colitis.
Gravitational Quenching by Clumpy Accretion in Cool Core Clusters: Convective Dynamical Response to Overheating

description: Many galaxy clusters pose a "cooling-flow problem", where the observed X-ray emission from their cores is not accompanied by enough cold gas or star formation. A continuous energy source is required to balance the cooling rate over the whole core volume. We address the feasibility of a gravitational heating mechanism, utilizing the gravitational energy released by the gas that streams into the potential well of the cluster dark-matter halo. We focus here on a specific form of gravitational heating in which the energy is transferred to the medium thorough the drag exerted on inflowing gas clumps. Using spheri-symmetric hydro simulations with a subgrid representation of these clumps, we confirm our earlier estimates that in haloes >=10^13 solar masses the gravitational heating is more efficient than the cooling everywhere. The worry was that this could overheat the core and generate an instability that might push it away from equilibrium. However, we find that the overheating does not change the global halo properties, and that convection can stabilize the cluster by carrying energy away from the overheated core. In a typical rich cluster of 10^{14-15}solar masses, with ~5% of the accreted baryons in gas clumps of ~10^8 solar masses, we derive upper and lower limits for the temperature and entropy profiles and show that they are consistent with those observed in cool-core clusters. We predict the density and mass of cold gas and the level of turbulence driven by the clump accretion. We conclude that gravitational heating is a feasible mechanism for preventing cooling flows in clusters.

description: A hyperbolic BC(n) Sutherland model involving three independent coupling constants that characterize the interactions of two types of particles moving on the half-line is derived by Hamiltonian reduction of the free geodesic motion on the group SU(n,n). The symmetry group underlying the reduction is provided by the direct product of the fixed point subgroups of two commuting involutions of SU(n,n). The derivation implies the integrability of the model and yields a simple algorithm for constructing its solutions.

description: In questo lavoro di ricerca si è voluto studiare da un punto di vista qualitativo l’impiego dei connettivi all’interno dei temi argomentativi di una classe di prima liceo, mettendo a frutto un itinerario didattico predisposto per accompagnare gli allievi verso una scrittura più coesa e coerente dei loro testi. Sul piano didattico, oltre a circoscrivere una casistica ragionata di connettivi impiegati dagli studenti, i risultati hanno confermato il valore nell’educazione alla scrittura di percorsi formativi pensati con una prospettiva testuale e sviluppati con l’obiettivo di risolvere una problematica puntuale. Sul piano pedagogico, benché la ricerca, per sua impostazione, non sia generalizzabile, ha dato utili indicazioni sul campione di riferimento, in particolare riguardo al processo di acquisizione dei traguardi formativi nel campo della scrittura di un testo argomentativo coeso e coerente, avvalorando dunque indirettamente il profilo del “docente-ricercatore”.

By mapping the problem onto a statistical-mechanical three-dimensional disordered Ising lattice gauge theory, we estimate via large-scale Monte Carlo simulations that color codes are stable against 4.5(2)% errors. Furthermore, by evaluating the skewness of the Wilson loop distributions, we introduce a very sensitive probe to locate first-order phase transitions in lattice gauge theories.

description: The recently discovered universal thermodynamic behaviour of dilute, strongly interacting Fermi gases also implies a universal structure in the many-body pair-correlation function at short distances, as quantified by the contact ${\cal I}$. This quantity is an excellent indicator of the presence of strong correlations in these systems, which provide a highly accessible physical model for other strongly correlated quantum fluids. Here we theoretically calculate the temperature dependence of this universal contact for a Fermi gas in free space and in a harmonic trap. At high temperatures above the Fermi degeneracy temperature, $T\gtrsim T_{F}$, we obtain a reliable non-perturbative quantum virial expansion up to third order. At low temperatures we compare different approximate strong coupling theories. These make different predictions, which need to be tested either by future experiments or advanced quantum Monte Carlo simulations. We conjecture that in the universal unitarity limit, the contact or correlation decreases monotonically with increasing temperature, unless the temperature is significantly lower than the critical temperature, $T\ll T_{c}\sim0.2T_{F}$. We also discuss briefly how to measure the universal contact either in homogeneous or harmonically trapped Fermi gases.

Higgs production in CP-violating supersymmetric cascade decays: probing the `open hole' at the Large Hadron Collider
Creators: name: Bandyopadhyay, Priyotosh
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A benchmark CP-violating supersymmetric scenario (known as 'CPX-scenario' in the literature) is studied in the context of the Large Hadron Collider (LHC). It is shown that the LHC, with low to moderate accumulated luminosity, will be able to probe the existing `hole' in the $m_{h_1}$-$\tanβ$ plane, which cannot be ruled out by the LEP data. We explore the parameter space with cascade decay of third generation squarks and gluino with CP-violating decay branching fractions. We propose a multi-channel analysis to probe this parameter space some of which are background free at an integrated luminosity of 5-10 fb$^{-1}$. Specially, multi-lepton final states ($3ł,\, 4ł$ and like sign di-lepton) are almost background free and have $5σ$ reach for the corresponding signals with very early data of LHC for both 14 TeV and 7 TeV center of mass energy.

description: Negli ultimi anni il numero dei passeggeri transitati dall’aeroporto di Lugano è pressappoco rimasto invariato se non leggermente diminuito. Il susseguirsi dei fallimenti dei partner commerciali, come Darwin Airlines e Skywork, sicuramente non ha migliorato la situazione economica portando l’aeroporto di Lugano a ricercare nuove idee di business. In questo contesto nasce l’idea di dare nuovo slancio allo scalo aeroportuale aumentando l’offerta commerciale con l’introduzione di voli regolari, stagionali e charter, operati con cosiddetti jet-privati, per il pubblico “business” in partenza dal terzo polo finanziario elvetico: Lugano
Large-scale flow dynamics and radiation in pulsar gamma-ray binaries

description: Several gamma-ray binaries show extended X-ray emission that may be associated to interactions of an outflow with the medium. Some of these systems are, or may be, high-mass binaries harboring young nonaccreting pulsars, in which the stellar and the pulsar winds collide, generating a powerful outflow that should terminate at some point in the ambient medium. This work studies the evolution and termination, as well as the related radiation, of the shocked-wind flow generated in high-mass binaries hosting powerful pulsars. A characterization, based on previous numerical work, is given for the stellar/pulsar wind interaction. Then, an analytical study of the further evolution of the shocked flow and its dynamical impact on the surrounding medium is carried out. Finally, the expected nonthermal emission from the flow termination shock, likely the dominant emitting region, is calculated. The shocked wind structure, initially strongly asymmetric, becomes a quasi-spherical, supersonically expanding bubble, with its energy coming from the pulsar and mass from the stellar wind. This bubble eventually interacts with the environment on ~pc scales, producing a reverse and, sometimes, a forward shock. Nonthermal leptonic radiation can be efficient in the reverse shock. Radio emission is expected to be faint, whereas X-rays can easily reach detectable fluxes. Under very low magnetic fields and large nonthermal luminosities, gamma rays may also be significant. We conclude that the complexity of the stellar/pulsar wind interaction is likely to be smoothed out outside the binary system, where the wind-mixed flow accelerates and eventually terminates in a strong reverse shock. This shock may be behind the extended X-rays observed in some binary systems. For very powerful pulsars, part of the unshocked pulsar wind may directly interact with the large-scale environment.

White feminist fragility : from part of the problem to radical allyship
Creators: name: MacIntyre, Tessa Mae
Publisher: name: University of British Columbia
Year: 2020

description: Feminism has a whiteness problem. Feminists of colour such as Audre Lorde, Angela Davis, and Kimberlé Crenshaw have been talking about this problem since the 1970’s, and the term ‘white feminism’ emerged to describe the predominantly white, upper-middle class, academic, heterosexual women who had taken control of mainstream feminist discourses. The problem being, after the early grassroots feminist consciousness raising of the 19th century, the feminist movement turned academic, an arena where radical feminists, lesbians, women of colour, and poor women were largely underrepresented. The result of this is decades of feminist theorizing, philosophy, and activism became focused on the problems of the privileged few. While feminists of colour started speaking out about this problem over 50 years ago, in 2017 the viral #MeToo movement brought to light the continued indifference towards women of colour and those who experience intersection systems of oppression. #MeToo was overwhelming focused on elite Hollywood actresses, and when it was later revealed that the phrase ‘Me Too’ had been in use by African American activist and community organizer Tarana Burke since 2007 to show solidarity to young, socioeconomically oppressed women and girls of colour, there were renewed calls to examine why the women in our society who hold the most privileged were also gaining the most attention for their causes. The purpose of this work is to define white feminism, understand the structures and strategies that support it, and explain how white supremacy functions to prevent advancement and maintain divisions between feminists. I will use concepts from writers like Audre Lorde, Layla Saad, and Marilyn Frye to analyse feminist discourses, past and present, in order to establish a pattern within feminism to centre whiteness. As a feminist who is white, I will call upon other white feminists to challenge institutional racism, decentre whiteness in feminist practice, and commit to radical anti-racism work as a main tenant of feminist activism.

description: We report significant influence of electric current on the orbital order-disorder transition in LaMnO3. The transition temperature T_OO, thermal hysteresis in the resistivity (rho) versus temperature (T) plot around T_OO, and latent heat L associated with the transition decrease with the increase in current density. Eventually, at a critical current density, L reaches zero. The transition zone, on the other hand, broadens with the increase in current density. The states at ordered, disordered, and transition zone are all found to be stable within the time window from ~10^-3 to ~10^4 seconds.

No extension of quantum theory can have improved predictive power

description: According to quantum theory, measurements generate random outcomes, in stark contrast with classical mechanics. This raises the question of whether there could exist an extension of the theory which removes this indeterminism, as suspected by Einstein, Podolsky and Rosen (EPR). Although this has been shown to be impossible, existing results do not imply that the current theory is maximally informative. Here we ask the more general question of whether any improved predictions can be achieved by any extension of quantum theory. Under the assumption that measurements can be chosen freely, we answer this question in the negative: no extension of quantum theory can give more information about the outcomes of future measurements than quantum theory itself. Our result has significance for the foundations of quantum mechanics, as well as applications to tasks that exploit the inherent randomness in quantum theory, such as quantum cryptography.

description: Dense particle packings acquire rigidity through a nonequilibrium jamming transition commonly observed in materials from emulsions to sandpiles. We describe athermal packings and their observed geometric phase transitions using fully equilibrium statistical mechanics and develop a microscopic many-body mean-field theory of the jamming transition for soft repulsive spherical particles. We derive analytically some of the scaling laws and exponents characterizing the transition and obtain predictions for microscopic correlation functions of jammed states that are amenable to experimental verifications, and whose accuracy we confirm using computer simulations.

description: Using the theory of optimal rocket trajectories in general relativity, recently developed in arXiv:1105.5235, we present a candidate for the minimum total integrated acceleration closed timelike curve in the Godel universe, and give evidence for its minimality. The total integrated acceleration of this curve is lower than Malament's conjectured value (Malament, 1984), as was already implicit in the work of Manchak (Manchak, 2011); however, Malament's conjecture does seem to hold for periodic closed timelike curves.

Direct Numerical Simulation of decaying two-dimensional turbulence in a no-slip square box using Smoothed Particle Hydrodynamics

Publisher: name: arXiv
Year: 2011
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: This paper explores the application of SPH to a Direct Numerical Simulation (DNS) of decaying turbulence in a two-dimensional no-slip wall-bounded domain. In this bounded domain, the inverse energy cascade, and a net torque exerted by the boundary, result in a spontaneous spin up of the fluid, leading to a typical end state of a large monopole vortex that fills the domain. The SPH simulations were compared against published results using a high accuracy pseudo-spectral code. Ensemble averages of the kinetic energy, enstrophy and average vortex wavenumber compared well against the pseudo-spectral results, as did the evolution of the total angular momentum of the fluid. However, while the pseudo-spectral results emphasised the importance of the no-slip boundaries as generators of long lived coherent vortices in the flow, no such generation was seen in the SPH results. Vorticity filaments produced at the boundary were always dissipated by the flow shortly after separating from the boundary layer. The kinetic energy spectrum of the SPH results was calculated using a SPH Fourier transform that operates directly on the disordered particles. The ensemble kinetic energy spectrum showed the expected k-3 scaling over most of the inertial range. However, the spectrum flattened at smaller length scales (initially less than 7.5 particle spacings and growing in size over time), indicating an excess of small-scale kinetic energy.

description: The theory of classical realizability is a framework in which we can develop the proof-program correspondence. Using this framework, we show how to transform into programs the proofs in classical analysis with dependent choice and the existence of a well ordering of the real line. The principal tools are: The notion of realizability algebra, which is a three-sorted variant of the well known combinatory algebra of Curry. An adaptation of the method of forcing used in set theory to prove consistency results. Here, it is used in another way, to obtain programs associated with a well ordering of R and the existence of a non trivial ultrafilter on N.

description: This paper constructs cellular resolutions for classes of noncommutative algebras, analogous to those introduced by Bayer-Sturmfels in the commutative case. To achieve this we generalise the dimer model construction of noncommutative crepant resolutions of toric algebras in dimension three by associating a superpotential and a notion of consistency to toric algebras of arbitrary dimension. For consistent algebras $A$, the coherent component of the fine moduli space of $A$-modules is constructed explicitly by GIT and provides a partial resolution of $\Spec Z(A)$. For abelian skew group algebras and algebraically consistent dimer model algebras, we introduce a cell complex $Δ$ in a real torus whose cells describe uniformly all maps in the minimal projective bimodule resolution of $A$. We illustrate the general construction of $Δ$ for an example in dimension four arising from a tilting bundle on a smooth toric Fano threefold to highlight the importance of the incidence function on $Δ$.
