Songs of soldiers : decolonizing political memory through poetry and song
Creators: name: Okot Bitek, Juliane
Publisher: name: University of British Columbia
Year: 2019

description: In January 1979, a ship ferrying armed Ugandan exiles and members of the Tanzanian army sank on Lake Victoria. Up to three hundred people are believed to have died on that ship, at least one hundred and eleven of them Ugandan. There is no commemoration or social memory of the account. This event is uncanny, incomplete and yet is an insistent memory of the 1978-79 Liberation war, during which the ship sank. From interviews with Ugandan war veterans, and in the tradition of the Luo-speaking Acholi people of Uganda, I present wer, song or poetry, an already existing form of resistance and reclamation, as a decolonizing project. Drawing from political memory in postcolonial, African, Black, Indigenous and Diaspora studies, I argue that truth-telling, a fundamental aspect of reconciliation and restoration of justice among the Acholi, can be achieved through poetic expression. This dissertation extends the technical definition of Okot p’Bitek’s Song school of poetry to include form and content and the space for social and political commentary in various voices and landscapes. The poet as historian, and the artist as ruler, both Okot p’Bitek’s concepts, are illustrated through “Songs of Soldiers”. This work is deeply rooted in displacement and the desire to return – continuing factors in where and how I think about and articulate myself.

description: Fundamental parameters and time-evolution of mass loss are investigated for post-main-sequence stars in the Galactic globular cluster 47 Tucanae (NGC 104). This is accomplished by fitting spectral energy distributions (SEDs) to existing optical and infrared photometry and spectroscopy, to produce a true Hertzsprung--Russell diagram. We confirm the cluster's distance as 4611 (+213, -200) pc and age as 12 +/- 1 Gyr. Horizontal branch models appear to confirm that no more RGB mass loss occurs in 47 Tuc than in the more-metal-poor omega Centauri, though difficulties arise due to inconsistencies between the models. Using our SEDs, we identify those stars which exhibit infrared excess, finding excess only among the brightest giants: dusty mass loss begins at a luminosity of ~ 1000 Lsun, becoming ubiquitous above 2000 Lsun. Recent claims of dust production around lower-luminosity giants cannot be reproduced, despite using the same archival Spitzer imagery.

description: Usually, photons are described by plane waves with a definite 4-momentum. In addition to plane-wave photons, "twisted photons" have recently entered the field of modern laser optics; these are coherent superpositions of plane waves with a defined projection hbar*m of the orbital angular momentum onto the propagation axis, where m is integer. In this paper, we show that it is possible to produce high-energy twisted photons by Compton backscattering of twisted laser photons off ultra-relativistic electrons. Such photons may be of interest for experiments related to the excitation and disintegration of atoms and nuclei, and for studying the photo-effect and pair production off nuclei in previously unexplored experimental regimes.

Classical stability of BTZ black hole in new massive gravity

description: We study the stability of the BTZ black hole in the new massive gravity. This is a nontrivial task because the linearized equation around the BTZ black hole background is a fourth order differential equation. Away from the critical point of $m^2 l^2=1/2$, this fourth order equation is split into two second order equations: one describes a massless graviton and the other is designed for a massive graviton, which could be obtained from the Fierz-Pauli action. In this case, calculating quasinormal modes leads to confirm the stability of the BTZ black hole. At the critical point, we derive two left and right logarithmic quasinormal modes from the logarithmic conformal field theory. Finally, we identify two $s$-massive modes propagating on the black hole background through the conventional black hole stability analysis.

Experimental determination of the state-dependent enhancement of the electron-positron momentum density in solids

description: The state-dependence of the enhancement of the electron-positron momentum density is investigated for some transition and simple metals (Cr, V, Ag and Al). Quantitative comparison with linearized muffin-tin orbital calculations of the corresponding quantity in the first Brillouin zone is shown to yield a measurement of the enhancement of the s, p and d states, independent of any parameterizations in terms of the electron density local to the positron. An empirical correction that can be applied to a first-principles state-dependent model is proposed that reproduces the measured state-dependence very well, yielding a general, predictive model for the enhancement of the momentum distribution of positron annihilation measurements, including those of angular correlation and coincidence Doppler broadening techniques.
Iron and sulfur control during pressure leaching of sulfide concentrates in the presence of chloride ions at 150°C
Creators: name: Abdul, Baseer
Publisher: name: University of British Columbia
Year: 2019

description: TECK and Vale operate their medium temperature copper and nickel sulfide concentrate leaching processes at 150°C. “Medium temperature” is used to describe a variety of processes that operate above the melting point of sulfur (119°C) but below the temperature where sulfur become highly viscous (159°C). During leaching, and depending upon various process parameters, iron (Fe) may precipitate as hematite, goethite, jarosite or other oxyhydroxide compounds. Hematite is the favored precipitate because it is the most environmentally (thermodynamically) stable and does not ad/absorb as much copper (Cu), nickel (Ni), or other solution constituents during precipitation. A better understanding of the formation and structure of these iron precipitates may elucidate key factors that would ultimately result in lower valuable metal losses and more stable leach residues. This thesis details the experimental work performed to clarify the conditions under which the precipitation of highly crystalline hematite occurs during medium temperature leaching of copper sulfide concentrates. Various process parameters at the lab scale were studied and classical, as well as newly developed, methods to identify the optimal conditions for hematite precipitation were employed. Higher acid concentrations resulted in increased copper extractions and favor the formation of hematite during concentrate leaching, rather than other metastable phases. Seeding with synthetic hematite resulted in more crystalline residues. Furthermore, commercially available water displacement formula ‘WD40®’ and other novel reagents (benzene sulfonic acid, phenyl phosphonic acid, decane, mineral oil) affect Fe precipitation and sulfur chemistry, leading to very different process outcomes such as improved extractions (from 98.0 to 99.2%) and larger, more easily separated, sulfur particles (from 20 µm to 1 mm). The solubility of ferrihydrite (and its main transformation product, hematite) increased with increasing acid concentration. The solid-state transformation of ferrihydrite to hematite was found to be the major mechanism. These results indicate that the ferrihydrite formed in the CESL process will eventually transform into hematite, but that solution potential will play an important role in the nature of iron oxide residue. Ferrihydrite transformation was not complete within the time (60 min) that is typically used in medium temperature leaching for the simple system studied here.

Tunneling conductance in strained graphene-based superconductor: Effect of asymmetric Weyl-Dirac fermions

description: Based on the BTK theory, we investigate the tunneling conductance in a uniaxially strained graphene-based normal metal (NG)/ barrier (I)/superconductor (SG) junctions. In the present model, we assume that depositing the conventional superconductor on the top of the uniaxially strained graphene, normal graphene may turn to superconducting graphene with the Cooper pairs formed by the asymmetric Weyl-Dirac electrons, the massless fermions with direction-dependent velocity. The highly asymmetrical velocity, vy/vx>>1, may be created by strain in the zigzag direction near the transition point between gapless and gapped graphene. In the case of the highly asymmetrical velocity, we find that the Andreev reflection strongly depends on the direction and the current perpendicular to the direction of strain can flow in the junction as if there was no barrier. Also, the current parallel to the direction of strain anomalously oscillates as a function of the gate voltage with very high frequency. Our predicted result is found as quite different from the feature of the quasiparticle tunneling in the unstrained graphene-based NG/I/SG conventional junction. This is because of the presence of the direction-dependent-velocity quasiparticles in the highly strained graphene system.

Dust production and mass loss in the Galactic globular cluster 47 Tucanae

description: Dust production among post-main-sequence stars is investigated in the Galactic globular cluster 47 Tucanae (NGC 104) based on infrared photometry and spectroscopy. We identify metallic iron grains as the probable dominant opacity source in these winds. Typical evolutionary timescales of AGB stars suggest the mass-loss rates we report are too high. We suggest that this is because the iron grains are small or elongated and/or that iron condenses more efficiently than at solar metallicity. Comparison to other works suggests metallic iron is observed to be more prevalent towards lower metallicities. The reasons for this are explored, but remain unclear. Meanwhile, the luminosity at which dusty mass loss begins is largely invariant with metallicity, but its presence correlates strongly with long-period variability. This suggests that the winds of low-mass stars have a significant driver that is not radiation pressure, but may be acoustic driving by pulsations.

description: The Bullet Cluster is a massive galaxy cluster at z=0.297 undergoing a major supersonic (Mach 3) merger event. Using Spitzer 24um images, IRAC data, optical imaging, and optical spectroscopy, we present the global star formation rate (SFR) of this unique cluster. Using a 90% spectroscopically complete sample of 37 non-AGN MIPS confirmed cluster members out to R<1.7 Mpc, and the Rieke et al. (2009) relation to convert from 24um flux to SFR, we calculate an integrated obscured SFR of 267 Msolar/yr and a specific star formation rate of 28 Msolar/yr per 10^14 Msolar. The cluster mass normalized integrated SFR of the Bullet Cluster is among the highest in a sample of eight other clusters and cluster mergers from the literature. Five LIRGs and one ULIRG contribute 30% and 40% of the total SFR of the cluster, respectively. To investigate the origin of the elevated specific SFR, we compare the infrared luminosity function (IR LF) of the Bullet Cluster to those of Coma (evolved to z=0.297) and CL1358+62. The Bullet Cluster IR LF exhibits an excess of sources compared to the IR LFs of the other massive clusters. A Schechter function fit of the Bullet Cluster IR LF yields L*=44.68+/-0.11 ergs/s, which is ~0.25 and 0.35 dex brighter than L* of evolved Coma and CL1358+62, respectively. The elevated IR LF of the Bullet Cluster relative to other clusters can be explained if we attribute the "excess" star-forming IR galaxies to a population associated with the infalling group that have not yet been transformed into quiescent galaxies. In this case, the timescale required for quenching star formation in the cluster environment must be longer than the timescale since the group's accretion -- a few hundred million years. We suggest that "strangulation" is likely to be an important process in the evolution of star formation in clusters.

description: Various astrophysical studies have motivated the investigation of the transport of high energy particles in magnetic turbulence, either in the source or en route to the observation sites. For strong turbulence and large rigidity, the pitch-angle scattering rate is governed by a simple law involving a mean free path that increases proportionally to the square of the particle energy. In this paper, we show that perpendicular diffusion deviates from this behavior in the presence of a mean field. We propose an exact theoretical derivation of the diffusion coefficients and show that a mean field significantly changes the transverse diffusion even in the presence of a stronger turbulent field. In particular, the transverse diffusion coefficient is shown to reach a finite value at large rigidity instead of increasing proportionally to the square of the particle energy. Our theoretical derivation is corroborated by a dedicated Monte Carlo simulation. We briefly discuss several possible applications in astrophysics.

description: Anomalous X-ray Pulsars (AXPs) and Soft Gamma-Ray Repeaters (SGRs) are young neutron stars (NSs) characterized by high X-ray quiescent luminosities, outbursts, and, in the case of SGRs, sporadic giant flares. They are believed to be powered by ultra-strong magnetic fields (hence dubbed magnetars). The diversity of their observed behaviours is however not understood, and made even more puzzling by the discovery of magnetar-like bursts from "low-field" pulsars. Here we perform long-term 2D simulations that follow the evolution of magnetic stresses in the crust; these, together with recent calculations of the breaking stress of the neutron star crust, allow us to establish when starquakes occur. For the first time, we provide a quantitative estimate of the burst energetics, event rate, and location on the neutron star surface, which bear a direct relevance for the interpretation of the overall magnetar phenomenology. Typically, an "SGR-like" object tends to be more active than an "AXP-like" object or a "high-$B$ radio pulsar", but there is no fundamental separation among what constitutes the apparent different classes. Among the key elements that create the variety of observed phenomena, age is more important than a small variation in magnetic field strength. We find that outbursts can also be produced in old, lower-field pulsars (B ~ a few x 10^{12} G), but those events are much less frequent than in young, high-field magnetars.

description: We analyze $e^{+}e^{-}\rightarrow γγ$, $e^{-}γ\rightarrow e^{-}γ$ and $γγ\rightarrow e^{+}e^{-} $ processes within the Seiberg-Witten expanded noncommutative scenario using polarized beams. With unpolarized beams the leading order effects of non commutativity starts from second order in non commutative(NC) parameter i.e. $O(Θ^2)$, while with polarized beams these corrections appear at first order ($O(Θ)$) in cross section. The corrections in Compton case can probe the magnetic component($\vecΘ_B$) while in Pair production and Pair annihilation probe the electric component($\vecΘ_E$) of NC parameter. We include the effects of earth rotation in our analysis. This study is done by investigating the effects of non commutativity on different time averaged cross section observables. The results which also depends on the position of the collider, can provide clear and distinct signatures of the model testable at the International Linear Collider(ILC).

description: The fermion representation for S = 1/2 spins is generalized to spins with arbitrary magnitudes. The symmetry properties of the representation is analyzed where we find that the particle-hole symmetry in the spinon Hilbert space of S =1/2 fermion representation is absent for S > 1/2. As a result, different path integral representations and mean field theories can be formulated for spin models. In particular, we construct a Lagrangian with restored particle-hole symmetry, and apply the corresponding mean field theory to one dimensional (1D) S = 1 and S = 3/2 antiferromagnetic Heisenberg models, with results that agree with Haldane's conjecture. For a S = 1 open chain, we show that Majorana fermion edge states exist in our mean field theory. The generalization to spins with arbitrary magnitude S is discussed. Our approach can be applied to higher dimensional spin systems. As an example, we study the geometrically frustrated S = 1 AFM on triangular lattice. Two spin liquids with different pairing symmetries are discussed: the gapped px + ipy-wave spin liquid and the gapless f-wave spin liquid. We compare our mean field result with the experiment on NiGa2S4, which remains disordered at low temperature and was proposed to be in a spin liquid state. Our fermionic mean field theory provide a framework to study S > 1/2 spin liquids with fermionic spinon excitations.

Datenaktivismus wird beispielhaft für Datenpolitiken ‚von unten‘ eingeführt und in reaktive und proaktive Praktiken und Taktiken differenziert, die reaktiv auf verschiedenen Ebenen auf Datenschutz zielen und/oder proaktiv in thematisch weiterreichende politische Projekte eingebettet sind. Für datenaktivistische Praktiken erweisen sich zahlreiche Fähigkeiten als bedeutsam, die in unterschiedlichen Ausprägungen als (Critical Big) Data Literacy/-ies modelliert werden. Diese verweisen auf die Schnittstelle von Politischer und Medienbildung in datafizierten Gesellschaften und münden im Text mit Gert Biesta in der Skizze eines Ignorant Digital/Data Citizen als erstrebenswerte politische Subjektfigur, die es vermag, zwischen universellem Gleichheitsstreben und weitgehender Unbestimmtheit zu vermitteln.

Grid integration of renewable energy sources via virtual synchronous generator
Creators: name: Dong, Shuan
Publisher: name: University of British Columbia
Year: 2019

description: Ongoing efforts toward environmentally sustainable electricity generation give rise to gradual displacement of synchronous generators by renewable energy resources (RESs). This paradigm shift reshapes power system dynamics and presents numerous challenges to reliable and efficient grid operations. For example, our power system will have reduced inertia and be at higher risk of instability, since the RESs generally interconnect to the grid via power-electronic converters with less or no inertia. Motivated by these challenges arising from RES integration, the concept of virtual synchronous generator (VSG) has been proposed to provide virtual inertia by emulating the SG dynamics in the RES controller. Among all VSG designs, synchronverter is a representative one with concise structure. However, this dissertation finds that conventional synchronverter designs lack in control degrees of freedom, require trial-and-error tuning process, synchronize with the grid slowly, and suffer from output-power coupling. Also, their active-power transfer capacity has not been studied, especially under weak-grid conditions. In order to address these problems and integrate more RESs into our system, my dissertation has five major contributions ranging from control design to tuning method to operation characteristics. First, in order to improve the synchronverter control degrees of freedom, I augment the synchronverter with a damping correction loop, which freely adjusts its response speed without affecting the steady-state performance. In order to simplify the tuning process, I propose a tuning method that evaluates the feasible pole-placement region and directly computes synchronverter parameters to achieve desired dynamics. My proposed tuning method completely avoids the trial-and-error tuning process and thus has overwhelming advantages over conventional tuning methods. Next, in order to synchronize the synchronverter quickly to the grid and enable the flexible ``plug-and-play" operation of RESs, this dissertation proposes a self-synchronizing synchronverter design with both fast self-synchronization speed and easily tuneable parameters. Then, to further improve the tracking performance, I propose a design with reduced output-power coupling. Finally, in order to integrate synchronverter-based RESs in weak grid, this dissertation analytically studies its active power transfer capacity and proposes two countermeasures to improve it. All my proposed designs and analyses are verified through extensive numerical or experimental studies.

description: The gauge structure of the four dimensional effective theory (4DET) arising from a pure Yang-Mills theory in five dimensions compactified on the orbifold $S^1/Z_2$ is reexamined on the basis of the BRST symmetry. The two scenarios that can arise are analyzed: if the gauge parameters propagate in the bulk, the excited Kaluza-Klein (KK) modes are gauge fields, but they are matter vector fields if these parameters are confined in the 3-brane. In the former case, it is shown that the 4DET is gauge invariant only if the compactification is carried out by using curvatures instead of gauge fields as fundamental objects. It is shown that the 4DET is governed by two types of gauge transformations, one determined by the KK zero modes of the gauge parameters and the other by the excited KK modes. The Dirac's method and the proper solution of the master equation are employed to show that the theory is subject to first class constraints. A gauge-fixing procedure to quantize the KK modes, that is covariant under the first type of gauge transformations, is introduced. The ghost sector induced by these gauge-fixing functions is derived on the basis of the BRST formalism. The effective quantum Lagrangian that links the interactions between light physics and heavy physics is presented. Concerning the radiative corrections of the excited KK modes on the light Green functions, the predictive character of this Lagrangian is stressed. In the case of the gauge parameters confined to the 3-brane, the known result in the literature is reproduced with some minor variants, although it is emphasized that the excited KK modes are not gauge fields, but matter fields that transform under the adjoint representation of $SU_4(N)$. The Dirac's method is employed to show that this theory is subject to both first and second class constraints.

The role of salicylic acid receptors NPR1 and NPR3/4 in PAMP-triggered immunity and effector-triggered immunity
Creators: name: Radojicic, Ana
Publisher: name: University of British Columbia
Year: 2020

description: Plants are constantly exposed to different pathogens in their environment and they have evolved complex defense strategies to avoid potential disease. The two general layers of plant defense are pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) and effector-triggered immunity (ETI). PTI is activated upon recognition of PAMPs by plant’s pattern recognition receptors (PRRs) localized on plasma membrane, while ETI is triggered when the presence of bacterial effector proteins is detected by intracellular plant nucleotide-binding leucine-rich repeat (NLR) proteins. Salicylic acid (SA) is a major regulator of plant immunity. A new model of SA signaling in Arabidopsis thaliana was recently established. Non-expressor of Pathogenesis-Related (PR) genes 1 (NPR1), NPR3 and NPR4 are SA receptors that have opposite roles in transcriptional regulation of defense-related genes. NPR1 functions as a transcriptional co-activator, while NPR3 and NPR4 are redundant transcriptional co-repressors of defense-related genes. Binding of SA activates NPR1, while it blocks transcriptional repression activity of NPR3 and NPR4. Although general function of these proteins in plant defense is understood, their requirement for different regulatory pathways in plant immunity is not entirely explored. In this thesis I analyze how NPR1 and NPR3/4 are involved in regulation of PTI response, and ETI response mediated by different NLR proteins. Infection assays with different strains of Pseudomonas syringae pv. tomato DC3000 revealed that PTI is regulated through both NPR1- and NPR3/4-dependent signaling, and that basal levels of SA contribute to PTI and AvrRPS4- or AvrRpt2-triggered ETI. The knock-out mutant npr1-1 and a dominant gain-of-function mutant allele npr4-4D fully suppress expression of PR1 and resistance to H.a. Noco2, but partially suppress dwarf morphology and constitutive PR2 expression of autoimmune snc1 mutant. Similarly, npr1-8 and npr4-4D partially suppress autoimmune phenotype of mkk1/2 mutants. Results of ion-leakage assay suggest that SA serves as a negative regulator of AvrRpt2-triggered hypersensitive response through NPR1 and NPR4-mediated signaling. My results support the new model of SA-dependent signaling, confirming that NPR1 and NPR3/4 function in parallel pathways. Although SA is the major regulator of plant defense, not all aspects of immune response rely entirely on SA receptors NPR1 and NPR3/4, confirming existence of SA-independent signaling.
