Hydrologic investigations of waste rock test piles in a permafrost environment
Creators: name: Zak, Jordan
Publisher: name: University of British Columbia
Year: 2017

description: Three 14 m tall waste rock test piles were constructed at the Diavik Diamond Mine, NWT, located in a region of continuous permafrost. Since 2006, instrumentation in the piles has been used to develop datasets characterizing the long-term geochemical, hydrologic, and thermal evolution of the waste rock. This thesis focuses on the hydrologic behaviour of two of the waste rock test piles; the Type III pile, considered as PAG material, and the Type I pile which was deconstructed in 2014, considered as NAG material. Complexity in the dataset is added by freeze-thaw processes occurring in this climate. The distribution of ice was mapped during the deconstruction of the Type I pile. Ice was found primarily in the batter regions, the cause of this was related to the infiltration profile across the crest and batters. Wind redistribution of snow results in a substantial snowpack on the batters with little on the crest. Infiltration through the crest occurs from rainfall alone, which is often low frequency and low magnitude. Snowmelt infiltration to the batters of the Type III pile was determined using an isotopic mass balance (𝛿D and 𝛿¹⁸O)- an estimated 77 mm/year representing a significant component of the water budget, about 74% of the annual outflow. Evidence of ice formation in this pile was provided by evaluating the storage of rainwater and trends in deuterium excess. A bromide tracer test on the Type III pile exhibited a breakthrough curve with a long tail and 46% mass recovery after ten years. The average pore water velocity was estimated to be 2-3 cm/day. Hypotheses were examined to explain low recovery of the tracer and the observed tailing, including the possibility of multirate mass transfer which assumes tailing is related to diffusion. Comparison of late time bromide behaviour to the migration of conservative blasting residuals suggests that tailing may also be influenced by low velocity flow paths. Concentration/mass loading histories from the two basal drains and basal collection lysimeters were highly variable, suggesting the solute transport system in the heterogeneous waste rock pile is complex and is potentially influenced by the presence of ice.
Quasi-bound states in the continuum: a dynamical coupled-channel calculation of axial-vector charmed mesons

description: Masses and widths of the charmed axial-vector mesons $D_1(2420)$, $D_1(2430)$, $D_{s1}(2536)$, and $D_{s1}(2460)$ are calculated nonperturbatively in the Resonance-Spectrum-Expansion model, by coupling various open and closed meson-meson channels to the bare $J^P=1^+$ $c\bar{q}$ ($q=u,d$) and $c\bar{s}$ states. The coupling to two-meson channels dynamically mixes and lifts the mass degeneracy of the spectroscopic $^3P_1$ and $^1P_1$ states, as an alternative to the usual spin-orbit splitting. Of the two resulting $S$-matrix poles in either case, one stays very close to the energy of the bare state, as a quasi-bound state in the continuum, whereas the other shifts considerably. This is in agreement with the experimental observation that the $D_1(2420)$ and $D_{s1}(2536)$ have much smaller widths than one would naively expect. The whole pattern of masses and widths of the axial-vector charmed mesons can thus be quite well reproduced with only two free parameters, one of which being already strongly constrained by previous model calculations. Finally, predictions for pole positions of radially excited axial-vector charmed mesons are presented.

description: We study a double quantum dot system coherently coupled to an electromagnetic resonator. A current through the dot system can create a population inversion in the dot levels and, within a narrow resonance window, a lasing state in the resonator. The lasing state correlates with the transport properties. On one hand, this allows probing the lasing state via a current measurement. On the other hand, the resulting narrow current peak allows resolving small differences in the dot properties, e.g., a small difference in the Zeeman splittings of the two dots. For realistic situations relaxation processes have pronounced consequences. Remarkably, they may even enhance the resolution between different spin states by releasing a trapped population in the off-resonant spin channel.

description: Theoretical predictions for the dynamic structure factor of a harmonically trapped Fermi superfluid near the BEC-BCS crossover are compared with recent Bragg spectroscopy measurements at large transferred momenta. The calculations are based on a random-phase (or time-dependent Hartree-Fock-Gorkov) approximation generalized to the strongly interacting regime. Excellent agreement with experimental spectra at low temperatures is obtained, with no free parameters. Theoretical predictions for zero-temperature static structure factor are also found to agree well with the experimental results and independent theoretical calculations based on the exact Tan relations. The temperature dependence of the structure factors at unitarity is predicted.

description: The one-dimensional Bose gas is an unusual superfluid. In contrast to higher spatial dimensions, the existence of non-classical rotational inertia is not directly linked to the dissipationless motion of infinitesimal impurities. Recently, experimental tests with ultracold atoms have begun and quantitative predictions for the drag force experienced by moving obstacles have become available. This topical review discusses the drag force obtained from linear response theory in relation to Landau's criterion of superfluidity. Based upon improved analytical and numerical understanding of the dynamical structure factor, results for different obstacle potentials are obtained, including single impurities, optical lattices and random potentials generated from speckle patterns. The dynamical breakdown of superfluidity in random potentials is discussed in relation to Anderson localization and the predicted superfluid-insulator transition in these systems.

description: We study the dynamics of individual agents in some kinetic models of wealth exchange, particularly, the models with savings. For the model with uniform savings, agents perform simple random walks in the "wealth space". On the other hand, we observe ballistic diffusion in the model with distributed savings. There is an associated skewness in the gain-loss distribution which explains the steady state behavior in such models. We find that in general an agent gains while interacting with an agent with a larger saving propensity.

Disentangling correlations in Multiple Parton Interactions

description: Multiple Parton Interactions are the tool to obtain information on the correlations between partons in the hadron structure. Partons may be correlated in all degrees of freedom and all different correlation terms contribute to the cross section. The contributions due to the different parton flavors can be isolated, at least to some extent, by selecting properly the final state. In the case of high energy proton-proton collisions, the effects of correlations in the transverse coordinates and in fractional momenta are, on the contrary, unavoidably mixed in the final observables. The standard way to quantify the strength of double parton interactions is by the value of the effective cross section and a small value of the effective cross section may be originated both by the relatively short transverse distance between the pairs of partons undergoing the double interaction and by a large dispersion of the distribution in multiplicity of the multi-parton distributions. The aim of the present paper is to show how the effects of longitudinal and transverse correlations may be disentangled by taking into account the additional information provided by double parton interactions in high energy proton-deuteron collisions.

Joint Unitary Triangularization for MIMO Networks

Year: 2010
Subjects: subject: Information Theory (cs.IT)

description: This work considers communication networks where individual links can be described as MIMO channels. Unlike orthogonal modulation methods (such as the singular-value decomposition), we allow interference between sub-channels, which can be removed by the receivers via successive cancellation. The degrees of freedom earned by this relaxation are used for obtaining a basis which is simultaneously good for more than one link. Specifically, we derive necessary and sufficient conditions for shaping the ratio vector of sub-channel gains of two broadcast-channel receivers. We then apply this to two scenarios: First, in digital multicasting we present a practical capacity-achieving scheme which only uses scalar codes and linear processing. Then, we consider the joint source-channel problem of transmitting a Gaussian source over a two-user MIMO channel, where we show the existence of non-trivial cases, where the optimal distortion pair (which for high signal-to-noise ratios equals the optimal point-to-point distortions of the individual users) may be achieved by employing a hybrid digital-analog scheme over the induced equivalent channel. These scenarios demonstrate the advantage of choosing a modulation basis based upon multiple links in the network, thus we coin the approach "network modulation".

Birational models of geometric invariant theory quotients
Creators: name: Cheung, Elliot
Publisher: name: University of British Columbia
Year: 2017

description: In this thesis, we study the problem of finding birational models of projective G-varieties with tame stabilizers. This is done with linearizations, so that each birational model may be considered as a (modular) compactification of an orbit space (of properly stable points). The main portion of the thesis is a re-working of a result in Kirwan's paper "Partial Desingularisations of Quotients of Nonsingular Varieties and their Betti Numbers", written in a purely algebro-geometric language. As such, the proofs are novel and require the Luna Slice Theorem as their primary tool. Chapter 1 is devoted to preliminary material on Geometric Invariant Theory and the Luna Slice Theorem. In Chapter 2, we present and prove a version of "Kirwan's procedure". This chapter concludes with an outline of some differences between the current thesis and Kirwan's original paper. In Chapter 3, we combine the results from Chapter 2 and a result from a paper by Reichstein and Youssin to provide another type of birational model with tame stabilizers (again, with respect to an original linearization).
Evolution of the differential transverse momentum correlation function with centrality in Au+Au collisions at $\sqrt{s_{NN}} = 200$ GeV

description: We present first measurements of the evolution of the differential transverse momentum correlation function, {\it C}, with collision centrality in Au+Au interactions at $\sqrt{s_{NN}} = 200$ GeV. {\it C} exhibits a strong dependence on collision centrality that is qualitatively similar to that of number correlations previously reported. We use the observed longitudinal broadening of the near-side peak of {\it C} with increasing centrality to estimate the ratio of the shear viscosity to entropy density, $η/s$, of the matter formed in central Au+Au interactions. We obtain an upper limit estimate of $η/s$ that suggests that the produced medium has a small viscosity per unit entropy.

This opens the possibility of electrical control of the intensity of light reflected inside a prism placed on top of the graphene layer, by switching between the regimes of total reflection and total absorption. The predicted effect can be used to build graphene-based opto-electronic switches.

The role of registered nurses in primary care and public health collaboration : a scoping review
Creators: name: Swanson, Monica Eleana
Publisher: name: University of British Columbia
Year: 2017

description: PURPOSE: As the British Columbia (BC) government works to improve primary care (PC) performance, attention to collaboration between PC and Public Health (PH) has been studied, especially improving health promotion in PC. Human resources and role optimization considerations are needed to operationalize this strategy. Nurses are the largest health care provider in BC, and yet nurses are an underutilized resource in the PC system in BC. This research aims to identify the roles of registered nurses (RN) in PC and PH collaboration and confirm if the BC RN scope of practice sufficiently covers the identified roles. METHODS: A scoping review of the current literature from North America, Western Europe and Australia/New Zealand from Jan. 2009 to Jan. 2016 was conducted. RESULTS: Twenty-three articles were obtained. Various nursing roles were identified that benefit PC/PH collaboration including: relationship builder, outreach professional, program facilitator and care coordinator. Through these roles, nurses supported vertical and horizontal transitions in chronic disease, communicable disease care and maternity care. Nurse’s roles were enacted at various levels from intrapersonal to organizational and systemic levels. The BC RN scope of practice supports the roles identified in this review, reaffirming that nurses are qualified to enact the roles. CONCLUSIONS: Based on their ability to work in a variety of roles and settings to promote collaboration between PC and PH, nurses could be more optimally utilized to support health care system change. Recommendations include political directives that support using nurses in system change. Health authorities could operationalize this by supporting more team-based nurses with an outreach role, especially for vulnerable populations, and utilizing nurses in inter-organization (such as PH to PC) program facilitation in chronic disease management. Education institutions need to ensure RN students are exposed to outreach experiences, and have practice working in the PC system, as well inter-organizational collaborative skills.

This algorithm is based on the numerical integration of the radial null geodesics and a local analysis of their behavior close to the singularity. As an application, we consider a collapsing spherical dust cloud, generate the corresponding conformal diagram and analyze the structure of the resulting singularity. A new bound on the initial data which guarantees that the singularity is visible from future null infinity is also obtained.

description: The recent Belle and BaBar measurements of the branching ratio of $B^+ \to τ^+ ν_τ$ indicate a significant deviation from the Standard Model prediction. We demonstrate that this measurement has a serious impact on models with minimal flavor violation involving a charged Higgs boson, ruling out a large portion of the currently-allowed parameter space. In the constrained minimal supersymmetric standard model, this creates a tension between the measurements of $B^+ \to τ^+ ν_τ$ and the anomalous magnetic moment of the muon, unless $\tanβ$ is small, $μ> 0$, and $A_0$ takes a large negative value. In fact, a very small region of the parameter space of this model, with small values of $m_0$ and $m_{1/2}$, survives all the constraints at 95% C.L.. It is remarkable that this specific region is still consistent with the lightest supersymmetric particle as the dark matter. Moreover, it predicts observable SUSY signals in the early runs of the LHC, even perhaps at 7 TeV. We also show that a consistent explanation for the deviation of the $B^+ \to τ^+ ν_τ$ branching ratio from the Standard Model can be achieved in a non-universal Higgs mass model, which could also predict early signals of supersymmetry at the LHC.

description: We determine the form of the complex shear modulus $G^*$ in soft sphere packings near jamming. Viscoelastic response at finite frequency is closely tied to a packing's intrinsic relaxational modes, which are distinct from the vibrational modes of undamped packings. We demonstrate and explain the appearance of an anomalous excess of slowly relaxing modes near jamming, reflected in a diverging relaxational density of states. From the density of states, we derive the dependence of $G^*$ on frequency and distance to the jamming transition, which is confirmed by numerics.

description: We use an analytic model to investigate the theoretical uncertainty on the thermal Sunyaev-Zel'dovich (SZ) power spectrum due to astrophysical uncertainties in the thermal structure of the intracluster medium. Our model accounts for star formation and energy feedback (from supernovae and active galactic nuclei) as well as radially dependent non-thermal pressure support due to random gas motions, the latter calibrated by recent hydrodynamical simulations. We compare the model against X-ray observations of low redshift clusters, finding excellent agreement with observed pressure profiles. Varying the levels of feedback and non-thermal pressure support can significantly change both the amplitude and shape of the thermal SZ power spectrum. Increasing the feedback suppresses power at small angular scales, shifting the peak of the power spectrum to lower ell. On the other hand, increasing the non-thermal pressure support has the opposite effect, significantly reducing power at large angular scales. In general, including non-thermal pressure at the level measured in simulations has a large effect on the power spectrum, reducing the amplitude by 50% at angular scales of a few arcminutes compared to a model without a non-thermal component. Our results demonstrate that measurements of the shape of the power spectrum can reveal useful information on important physical processes in groups and clusters, especially at high-redshift where there exists little observational data. Comparing with the recent South Pole Telescope measurements of the small-scale cosmic microwave background power spectrum, we find our model reduces the tension between the values of sigma_8 measured from the SZ power spectrum and from cluster abundances.

Special education administrators and workload determination for teachers of students with visual impairments : a Delphi study
Creators: name: Wilton, Adam
Publisher: name: University of British Columbia
Year: 2017

description: Itinerant teachers of students with visual impairments (TSVIs) support access to the curriculum for students with visual impairments by promoting the use of adaptive tools, materials, and strategies to mitigate the impact of visual impairment on learning and development. Traditionally, the number of students served by the TSVI is referred to as a “caseload” and is used as an indicator of the breadth of the TSVI’s professional responsibilities. This study uses “workload” as a more inclusive term that encompasses the full scope of the itinerant TSVIs’ professional practice, including direct, consultative, and indirect service to students with visual impairments and their educational teams. Given the low incidence of visual impairment among children and youth, many special education administrators responsible for staffing TSVI positions do not have an awareness of the specialized educational programming needs of these learners that factor into TSVI workload. Resources targeted to special education administrators that consider a broad scope of educational programming, personnel, and policy factors are required to support data-driven workload determinations for itinerant TSVIs. The purpose of the study was to develop a set of factors that experts rate as important considerations in the process of TSVI workload determination. This study was conducted using the Delphi approach, an iterative process through which consensus is built among a panel of knowledgeable experts on a topic of specialized interest. Panelists rated the importance of 45 initial educational programming, personnel, and policy-level factors with 22 panelist-nominated factors added in the second survey round. Four survey rounds were required to arrive at a set of 45 confirmed factors. Each factor included in the final set of confirmed factors had a rating at a high level of importance, strong consensus among panelists, and stability across survey rounds. After adjusting for the total number of initial and nominated factors in each thematic cluster, educational programming factors accounted for the greatest proportion of confirmed factors, followed by personnel-level factors and policy-level factors. The results of the study are intended to provide special education administrators with a set of evidence-based factors to inform the process of workload determination for itinerant TSVIs.

description: We experimentally investigate the mode characteristics of multimode radiation fields propagating through frequency dependent Gaussian channels. After manipulating the twin beams emitted from a conventional parametric down-conversion source via spectral filtering, we study the changes in their mode characteristics, utilizing the joint normalized correlation functions. While filtering reduces the number of spectral modes, it also leads to an apparent mode mismatch, which destroys the perfect photon-number correlation between the twin beams, and influences the mode properties of heralded states.

description: For years, the quantum/reversible circuit community has been convinced that: a) the addition of auxiliary qubits is instrumental in constructing a smaller quantum circuit; and, b) the introduction of quantum gates inside reversible circuits may result in more efficient designs. This paper presents a systematic approach to optimizing reversible (and quantum) circuits via the introduction of auxiliary qubits and quantum gates inside circuit designs. This advances our understanding of what may be achieved with a) and b).

description: It is known that the number of different classical messages which can be communicated with a single use of a classical channel with zero probability of decoding error can sometimes be increased by using entanglement shared between sender and receiver. It has been an open question to determine whether entanglement can ever increase the zero-error communication rates achievable in the limit of many channel uses. In this paper we show, by explicit examples, that entanglement can indeed increase asymptotic zero-error capacity, even to the extent that it is equal to the normal capacity of the channel. Interestingly, our examples are based on the exceptional simple root systems E7 and E8.

Resistance in and of the university : neoliberalism, empire, and student activist movements
Creators: name: Carey, Kristin
Publisher: name: University of British Columbia

description: In a time of global neoliberal precarity that follows from perpetual war, uncontracted labour, and heightened forced global migration to name a few contemporary violences, there has been a noticeable rise of protest both nationally and also localized to university campuses in the United States. Experiencing the historical weight of racism, classism, sexism, ableism, and nationalism on college campuses, students are claiming public and digital spaces as sites of resistance. These movements trace connections to the accomplishments of the civil and academic rights movements of the 1960s, by again and still asking for institutional responses to white supremacy and systems of oppression (Ferguson, 2012) while realizing they take different shapes due to the international, national, and local forces that call them into being. This paper provides some preliminary mapping of the student activist and institutional responses to student movements. Necessarily, my work also historicizes the how the university is shaped by national and global political and economic violence and structures—namely, neoliberalism and empire. Using feminist, queer, and critical race theory as my theoretical and methodological frameworks, I examine two case studies of student protest: The University of California, San Diego of 2009 and the University of Missouri in 2015. I ask questions about the production of student political subjectivity, as both process and product. Using what Guattari and Rolnik (2008) term capitalist subjectivity, I am particularly interested in analyzing how a particular, perhaps alternate kind of student (activist) political subject(ivity) emerges in/out of confrontation with the university’s normative student subjectivity, but nonetheless constituted in relation to it. This thesis works within a historico-political moment (2009-2015), and hopes to both interrogate and understand the university, its strategic gains for social justice, and what we make of its role in the here and now.
Density response of a trapped Fermi gas: a crossover from the pair vibration mode to the Goldstone mode

description: We consider the density response of a trapped two-component Fermi gas. Combining the Bogoliubov-deGennes method with the random phase approximation allows the study of both collective and single particle excitations. Calculating the density response across a wide range of interactions, we observe a crossover from a weakly interacting pair vibration mode to a strongly interacting Goldstone mode. The crossover is associated with a depressed collective mode frequency and an increased damping rate, in agreement with density response experiments performed in strongly interacting atomic gases.

Dynamics-based centrality for general directed networks

description: Determining the relative importance of nodes in directed networks is important in, for example, ranking websites, publications, and sports teams, and for understanding signal flows in systems biology. A prevailing centrality measure in this respect is the PageRank. In this work, we focus on another class of centrality derived from the Laplacian of the network. We extend the Laplacian-based centrality, which has mainly been applied to strongly connected networks, to the case of general directed networks such that we can quantitatively compare arbitrary nodes. Toward this end, we adopt the idea used in the PageRank to introduce global connectivity between all the pairs of nodes with a certain strength. Numerical simulations are carried out on some networks. We also offer interpretations of the Laplacian-based centrality for general directed networks in terms of various dynamical and structural properties of networks. Importantly, the Laplacian-based centrality defined as the stationary density of the continuous-time random walk with random jumps is shown to be equivalent to the absorption probability of the random walk with sinks at each node but without random jumps. Similarly, the proposed centrality represents the importance of nodes in dynamics on the original network supplied with sinks but not with random jumps.

description: We review two novel techniques used to calculate tree-level scattering amplitudes efficiently: MHV diagrams, and on-shell recursion relations. For the MHV diagrams, we consider applications to tree-level amplitudes and focus in particular on the N=4 supersymmetric formulation. We also briefly describe the derivation of loop amplitudes using MHV diagrams. For the recursion relations, after presenting their general proof, we discuss several applications to massless theories with and without supersymmetry, to theories with massive particles, and to graviton amplitudes in General Relativity. This article is an invited review for a special issue of Journal of Physics A devoted to "Scattering Amplitudes in Gauge Theories".

description: We have carried out the first general submillimeter analysis of the field towards GRSMC 45.46+0.05, a massive star forming region in Aquila. The deconvolved 6 deg^2 (3\degree X 2\degree) maps provided by BLAST in 2005 at 250, 350, and 500 micron were used to perform a preliminary characterization of the clump population previously investigated in the infrared, radio, and molecular maps. Interferometric CORNISH data at 4.8 GHz have also been used to characterize the Ultracompact HII regions (UCHIIRs) within the main clumps. By means of the BLAST maps we have produced an initial census of the submillimeter structures that will be observed by Herschel, several of which are known Infrared Dark Clouds (IRDCs). Our spectral energy distributions of the main clumps in the field, located at ~7 kpc, reveal an active population with temperatures of T~35-40 K and masses of ~10^3 Msun for a dust emissivity index beta=1.5. The clump evolutionary stages range from evolved sources, with extended HII regions and prominent IR stellar population, to massive young stellar objects, prior to the formation of an UCHIIR.The CORNISH data have revealed the details of the stellar content and structure of the UCHIIRs. In most cases, the ionizing stars corresponding to the brightest radio detections are capable of accounting for the clump bolometric luminosity, in most cases powered by embedded OB stellar clusters.

description: The metal-poor, fundamental-mode (P0) and first-overtone (P1) Cepheids in the dwarf galaxies IC 1613, WLM, Pegasus, Sextans A, Sextans B, and Leo A are compared with the about equally metal-poor Cepheids of the Small Magellanic Cloud (SMC). The period-color (P-C) and period-luminosity (P-L) relations of the seven galaxies are indistinguishable, but differ distinctly from those in the Large Magellanic Cloud (LMC) and the solar neighborhood. Adopting (m-M)^{0}_{SMC}=18.93 from independent evidence, one can determine reliable distance moduli for the other dwarf galaxies of (m-M)^{0} = 24.34+/-0.03, 24.95+/-0.03, 24.87+/-0.06, 25.60+/-0.03 (mean for Sextans A & B), and 24.59+/-0.03, respectively.

description: We study the contribution of antisymmetric tensor unparticle mediation to the charged lepton electric dipole moments and restrict the free parameters of the model by using the experimental upper bounds. We observe that the charged lepton electric dipole moments are strongly sensitive to the the scaling dimension d_U and the fundamental scales M_U and Λ_U. The experimental current limits of electric dipole moments are reached for the small values of the scaling dimension d_U.
