description: In R.D. Sorkin's framework for logic in physics a clear separation is made between the collection of unasserted propositions about the physical world and the affirmation or denial of these propositions by the physical world. The unasserted propositions form a Boolean algebra because they correspond to subsets of an underlying set of spacetime histories. Physical rules of inference, apply not to the propositions in themselves but to the affirmation and denial of these propositions by the actual world. This physical logic may or may not respect the propositions' underlying Boolean structure. We prove that this logic is Boolean if and only if the following three axioms hold: (i) The world is affirmed, (ii) Modus Ponens and (iii) If a proposition is denied then its negation, or complement, is affirmed. When a physical system is governed by a dynamical law in the form of a quantum measure with the rule that events of zero measure are denied, the axioms (i) - (iii) prove to be too rigid and need to be modified. One promising scheme for quantum mechanics as quantum measure theory corresponds to replacing axiom (iii) with axiom (iv) Nature is as fine grained as the dynamics allows.

description: This paper investigates the effect of network topology on the fair allocation of network resources among a set of agents, an all-important issue for the efficiency of transportation networks all around us. We analyse a generic mechanism that distributes network capacity fairly among existing flow demands. The problem can be solved by semi-analytical methods on a nearest neighbour graph with one source and sink pair, when transport occurs over shortest paths. For this setup, we uncover a broad range of patterns of intersecting shortest paths as a function of the distance between the source and the sink. When the number of intersections is the maximum and the distance between the source and the sink is large, we find that a fair allocation implies a decrease of at least 50% from the maximum throughput. We also find that the histogram of the flow allocations assigned to the agents decays as a power-law with exponent -1. Our semi-analytical framework suggests possible explanations for the well-known reduction of the throughput in fair allocations. It also suggests that the combination of network topology and routing rules can lead to highly uneven (but fair) distributions of resources, a remark of caution to network designers.

description: The body of literature surrounding interactions between the microbiota, T cells and B cells has grown substantially in recent years, but several questions remain. This thesis worked towards filling knowledge gaps in this field. Research from the Geuking lab has shown that mice primed with E. coli_gp61 produced a significantly greater E. coli-specific immunoglobulin (Ig) response compared to mice challenged with wild-type (WT) E. coli. My research has shown these antimicrobial antibodies to be T cell dependent with Class Switch Recombination (CSR) increasing bacterial specific IgM on day 7 and bacterial specific IgG on day 14. Following this finding, it was determined that in vitro fitness of E. coli is comparable between WT E. coli, E. coli_gp61 and E. coli_OmpC KO, but these bacteria display unique metabolic profiles with E. coli_gp61 and E. coli_OmpC KO displaying the most similarities. To test the effect of bacterial antigens in the thymus as well as the effect of metabolites on selection in the thymus, an organotypic thymic culture system was then utilized. Thymic slices were able to recognize pure peptide but were unable to independently process and present bacterial antigens. Intestinal-derived bacterial metabolites were able to reach the thymus and modulate negative selection and nTreg generation shown by GF mice producing more nTregs and having less CD4+CD8+ cells in response to self-peptide compared to sDMDMm2 or SPF mice. Finally, Recent Thymic Emigrants (RTEs) showed comparable thymic output in vivo between GF and SPF mice. Overall, these results show important differences between both thymic development of microbe-specific T cells and their effects on systemic antimicrobial antibody responses in GF and SPF mice, adding to our body of knowledge surrounding microbiota, T cell and B cell interactions.

description: The regular \Z^r-covers of a finite cell complex X are parameterized by the Grassmannian of r-planes in H^1(X,\Q). Moving about this variety, and recording when the Betti numbers b_1,..., b_i of the corresponding covers are finite carves out certain subsets Ω^i_r(X) of the Grassmannian. We present here a method, essentially going back to Dwyer and Fried, for computing these sets in terms of the jump loci for homology with coefficients in rank 1 local systems on X. Using the exponential tangent cones to these jump loci, we show that each Ω-invariant is contained in the complement of a union of Schubert varieties associated to an arrangement of linear subspaces in H^1(X,\Q). The theory can be made very explicit in the case when the characteristic varieties of X are unions of translated tori. But even in this setting, the Ω-invariants are not necessarily open, not even when X is a smooth complex projective variety. As an application, we discuss the geometric finiteness properties of some classes of groups.

"The problems of sickness follow me" : embodied structural violence and social suffering among singlemothers in post-socialist Tanzania
Creators: name: Houmphan, Rachel
Publisher: name: University of British Columbia
Year: 2013

description: This thesis seeks to better understand the pervasiveness of suffering amongst poor single Tanzanian mothers in times of severe economic austerity following the implementation of IMF/World Bank neoliberal structural adjustment policies. These policies, which restructured the economy through liberalization, were implemented due to economic crises and external pressure from donors in the late 1980s and continue today. Based on six months of ethnographic research, I draw on participant observation of everyday life in Mbande, a village on the outskirts of Dar es Salaam, oral life history interviews and focus group discussions with single mothers and the broader community. Focusing mainly on Tanzania’s postcolonial context, this thesis relies on the unique capacities of ethnography and oral life histories to show the impacts of radical economic restructuring, and its intersections with gender and other markers of social difference. The thesis examines how these have impacted the livelihoods and health of poor single mothers. While there is sufficient literature to suggest that many people in Tanzania live in conditions of severe poverty, little research that has been done to understand the ways in which suffering in people’s everyday lives is locally manifested as a result of economic, social and medical inequalities. Conditions of poverty and suffering are too often conveyed with a sense of timeless essence, often locating the “fate” and “doom” of Africa in discourses of backwards or unenlightened “African” cultural practices and various corrupt perpetrators. Departing from such an approach, and using a theoretical framework of structural violence and social suffering, I illustrate how the conditions of viscerally experienced suffering, especially by poor single mothers, are perpetuated by long term and systemic pathologies which “follow them” and in seemingly quotidian ways. By analyzing excerpts from two detailed oral life history interviews, I demonstrate the ways in which multiple factors align in harmful and unfavorable ways for single mothers in Mbande: I show how the suffering the people speak of in their lives is not the result of ill intention or will of any one person or governing body, but arises from a more everyday violence of systematic neglect and limits of care.

description: LHC experiments have placed strong bounds on the production of supersymmetric colored particles (squarks and gluinos), under the assumption that all flavors of squarks are nearly degenerate. However, the current experimental constraints on stop squarks are much weaker, due to the smaller production cross section and difficult backgrounds. While light stops are motivated by naturalness arguments, it has been suggested that such particles become nearly impossible to detect near the limit where their mass is degenerate with the sum of the masses of their decay products. We show that this is not the case, and that searches based on missing transverse energy (MET) have significant reach for stop masses above 175 GeV, even in the degenerate limit. We consider direct pair production of stops, decaying to invisible LSPs and tops with either hadronic or semi-leptonic final states. Modest intrinsic differences in MET are magnified by boosted kinematics and by shape analyses of MET or suitably-chosen observables related to MET. For these observables we show that the distributions of the relevant backgrounds and signals are well-described by simple analytic functions, in the kinematic regime where signal is enhanced. Shape analyses of MET-related distributions will allow the LHC experiments to place significantly improved bounds on stop squarks, even in scenarios where the stop-LSP mass difference is degenerate with the top mass. Assuming 20/fb of luminosity at 8 TeV, we conservatively estimate that experiments can exclude or discover degenerate stops with mass as large as ~ 360 GeV and 560 GeV for massless LSPs.

description: Abstract: The environmental impacts of packaging have been discussed in scientific literature (e.g. Civancik-Uslu et al. 2019) and among political authorities (e.g. European Commission (EC)) alike. Concerns regarding environmental impacts of packaging and overall efficiency in material use have led to numerous regulations and strategies, for instance the Packaging and Packaging Waste Directive (European Union 1994), as well as the Strategy for Plastics in a Circular Economy (EC 2018). However, in most cases, the function of packaging (e.g. product protection) can be fulfilled using alternative solutions, like using different materials (e.g. glass or plastics) or other business models (e.g. refund, refill systems), which would also support the circularity of products in use (Lofthouse et al. 2017). To date, there have not been many empirical studies approaching a comparison of the environmental impacts associated with these distinct solutions. This study presents a comparative LCA of various packaging materials (glass, PE, PLA) as well as different business model solutions (single-use, refill system) for a standard packaging of a cosmetic product. A streamlined LCA analysis from cradle to grave has been performed. The environmental impacts of a refill system were compared with the impacts of the single-use packaging solution. Due to the low level of technological maturity of the refill station, the environmental break-even point was calculated in comparison with a single-use packaging for a cosmetic product. The results show that switching the material to a more sustainable alternative can provide several environmental benefits. However, alternative business models have a stronger influence on the environmental impacts than material selection. This does not necessarily imply that they always provide environmental advances, but that factors such as user frequency, customer loyalty and behavior are decisive. Accordingly, we propose to integrate these factors into the environmental assessment of packaging solutions in the future.

description: Using dynamical Monte-Carlo simulations we observe the occurrence of an unexpected shock wave in driven diffusive systems with two conserved species of particles. This U-shock is microscopically sharp, but does not satisfy the usual criteria for the stability of shocks. Exact analysis of the large-scale hydrodynamic equations of motion reveals the presence of an umbilical point which we show to be responsible for this phenomenon. We prove that such an umbilical point is a general feature of multi-species driven diffusive systems with reflection symmetry of the bulk dynamics. We argue that an U-shock will occur whenever there are strong repulsive interactions such that the current-density relation develops a double-well and the umbilical point becomes isolated.

Accuracy Assessment and Enhancement of TOF-based UWB RTLS and Improvement on Auto-positioning

Publisher: name: Schulich School of Engineering
Year: 2021
Subjects: subject: Engineering--Civil

description: Studies in the past decades have shown Real Time Location Systems (RTLS) have great potential in reducing possible injuries and enhancing productivity. Ultra-Wide Band (UWB), among all the RTLS, has demonstrated the best suitability for construction site conditions due to its higher accuracy, lower dependency on the Line-Of-Site, less signal attenuation and multipath effect. The objective of this study is to investigate and enhance the feasibility of a TOF-based UWB RTLS on construction site applications. The three subobjectives are:1.To assess the performance of the TOF-based UWB under LOS. 2.To develop a new auto-positioning approach: (1) with high accuracy; (2) without BLE or WLAN requirements; (3) without configuration angle and height requirements; (4) without complex input requirements; and (5) has the capability to compute 3D (X, Y, and Z) locations of the anchors. 3.To assess and enhance the accuracy of the TOF-based UWB RTLS under NLOS in construction sites.Through the feasibility assessments conducted in this study, the TOF-based UWB RTLS is verified with high reliability for the performance of the tags, high static and dynamic accuracy, low time latency, and low multiple tags effect. The proposed auto-positioning methodology improved the accuracy by more than 70% and overcame the application barriers of the inherent auto-positioning. The accuracy assessment under NLOS confirmed that large bias rather than noise is induced when multi-path effect exists. Moreover, the proposed residual analysis approach improved the location estimation accuracy by more than 60%.
Improving Steam-Assisted Gravity Drainage using Conformance Control Agents: Oil-in-Water Emulsion and Steam Foam

description: Steam-assisted gravity drainage (SAGD) is a commercially successful thermal recovery method for extracting bitumen in the deep oil sands reservoirs. Over the years, many modifications of the original SAGD process have been proposed to improve the performance, yet the results of these modifications remain unsatisfactory. In addition, the efficiency of SAGD is significantly impacted by the intrinsic heterogeneity of the oil sands reservoir. In this study, we investigate the feasibility of improving SAGD with conformance control agents; namely oil-in-water (O/W) emulsion and steam foam. We first studied the effect of oil phase viscosity on the plugging performance of O/W emulsion using sandpack flow test. A comprehensive experimental investigation was then conducted to understand the steam foam propagation and its potential for conformance control. In particular, the effect of liquid drainage on steam foam behavior in the porous media was studied. Finally, numerical investigation was carried out to evaluate FA-SAGD performance under different injection strategies and reservoir heterogeneities. Experimental results show that oil viscosity of O/W emulsion considerably affects its plugging ability. Frictional resistance increases as oil viscosity increases, but the rate of increment tapers down significantly. Stable steam foam can be generated in high permeability sandpacks, while the foam behind the moving foam front quickly coarsens in low permeability packs. The effect of liquid drainage is more significant when weak steam foam is present in the porous media. Successful profile control is achieved in parallel-sandpack flow tests and a detailed multi-cycle diversion of flow is identified. Simulation results further demonstrate that application of steam foam generally improves the energy efficiency and oil production of SAGD. For a homogeneous reservoir, slug injection when the steam chamber is fully developed yields the largest increment in oil recovery relative to SAGD. A 365-day foam slug injection results in 11.2% increment in oil recovery with satisfactory production rate. In contrast, early slug injection after preheating is recommended for heterogeneous reservoir with permeability variation in the horizontal direction. To conclude, O/W emulsion and steam foam can be applied at different stages of SAGD operation and both show great potential for improving SAGD performance.

description: We find strong relationships between the zero-divisor graphs of apparently disparate kinds of nilpotent-free semigroups by introducing the notion of an \emph{Armendariz map} between such semigroups, which preserves many graph-theoretic invariants. We use it to give relationships between the zero-divisor graph of a ring, a polynomial ring, and the annihilating-ideal graph. Then we give relationships between the zero-divisor graphs of certain topological spaces (so-called pearled spaces), prime spectra, maximal spectra, tensor-product semigroups, and the semigroup of ideals under addition, obtaining surprisingly strong structure theorems relating ring-theoretic and topological properties to graph-theoretic invariants of the corresponding graphs.

Citizen science in conservation biology : best practices in the geoweb era
Creators: name: Parfitt, Ian
Publisher: name: University of British Columbia
Year: 2013

description: Conservation biology emerged as an activist discipline in the 1980s in response to increasing evidence that Earth is undergoing a biodiversity crisis. Building on foundations of biological science and applied resource management methods, this new discipline called upon its practitioners to both undertake scientific research to improve understanding of all species and ecosystems, and to take social and political action to protect and enhance endangered biodiversity. In the current era of declining budgets for biodiversity research and management, volunteer citizen science is gaining recognition as an important strategy for expanding and extending the work of embattled professional conservation biologists. New technologies such as handheld computers, GPS, GIS, interactive map services, and the internet, and the wide-spread availability, adoption and adaptation of these technologies by the general public, have created an environment where citizens can be rapidly mobilized to gather, process, and communicate data in support of conservation biology’s twin goals. In this thesis I explore citizen science within conservation biology and within the concept of the GeoWeb. I trace the history of citizen science in biology since the late 1800s to the current day, to better understand the practice and its contribution to conservation science. I find that citizen science is often employed to undertake research at large spatial scales, and that often location is a key attribute of the data citizens gather; as a result, the infrastructure and methods of the GeoWeb are fundamental to many citizen science projects. In the spirit of conservation biology, I pair my research of citizen science with the assembly of a set of best practices for increasing the impact of the practice on the conservation agenda, and then evaluate twelve current citizen science projects currently underway in British Columbia against these practices. I conclude that citizen participation in biological science furthers both of conservation biology’s goals: it both increases our body of knowledge about biodiversity, and helps to develop an informed and empowered constituency for conservation action and ecologically sustainable stewardship.
title: Needs and Motivations Underlying Collective Narcissism and In-group Identification
Creators: name: Eker, Irem
Publisher: name: University of Kent
Year: 2021

description: Collective narcissism reflects a belief in the greatness of one's in-group requiring recognition from other groups and has been linked to outgroup hostility, while in-group identification free of collective narcissism (secure in-group identity) has been linked to positive attitudes. Since the underpinning mechanisms of either are less well understood, this project investigates the needs and motives underlying each form of in-group identity. Chapter 1 suggests that while collective narcissism is likely to emanate from thwarted personal needs, secure in-group identity might be rooted in satisfied needs. The empirical chapters (chapters 2-4) examine individual and group needs as well as different types of motivations as psychological mechanisms underlying collective narcissism versus secure in-group identity. Studies 1-4 (Chapter 2), testing relationships between the need to belong and collective narcissism and secure in-group identity, yielded non-significant results. In the longitudinal Study 5 (Chapter 3), frustrated competence and dissatisfaction with personal relationships predicted higher collective narcissism over time. Satisfied personal autonomy and less competence frustration predicted higher secure in-group identity over time. In Study 6 (Chapter 3), frustrated group needs were related to higher collective narcissism both among advantaged and disadvantaged groups. Chapter 4 builds on self-determination theory and literature on religious orientations to examine types of motivations associated with the two types of in-group identity. In Studies 7, 8, and 10, self-determined motivations were associated with secure in-group identity whereas non-self-determined motivations were related to collective narcissism. In Studies 9 and 10, while intrinsic religiosity was associated with both collective narcissism and secure in-group identity, extrinsic religiosity was related to collective narcissism only. I conclude in Chapter 5. This dissertation provides evidence that frustrated needs and non-self-determined motives to identify are associated with collective narcissism while less frustrated needs and self-determined motives to identify are related to a more secure in-group identity.

description: The evolution of different magnetic structures of non-centrosymmetric Ba2CuGe2O7 is systematically studied as function of the orientation of the magnetic field H. Neutron diffraction in combination with measurements of magnetization and specific heat show a virtually identical behaviour of the phase diagram of Ba2CuGe2O7 for H confined in both the (1,0,0) and (1,1,0) plane. The existence of a recently proposed incommensurate double-k AF-cone phase is confirmed in a narrow range for H close to the tetragonal c-axis. For large angles enclosed by H and the c-axis a complexely distorted non-sinusoidal magnetic structure has recently been observed. We show that its critical field Hc systematically increases for larger canting. Measurements of magnetic susceptibility and specific heat finally indicate the existence of an incommensurate/commensurate transition for H /sim 9 T applied in the basal (a,b)-plane and agree with a non-planar, distorted cycloidal magnetic structure.

description: We study the problem of conformal deformation of Riemannian structure to constant scalar curvature with zero mean curvature on the boundary. We prove compactness for the full set of solutions when the boundary is umbilic and the dimension $n \leq 24$. The Weyl Vanishing Theorem is also established under these hypotheses, and we provide counter-examples to compactness when $n \geq 25$. Lastly, our methods point towards a vanishing theorem for the umbilicity tensor, which is anticipated to be fundamental for a study of the nonumbilic case.

FUTURE PATHWAYS FOR THE UTILIZATION OF 2,5-FURANDICARBOXYLIC ACID IN PACKAGING APPLICATIONS

description: Abstract: Plastics make up an integral part of everyday life, with the packaging market representing by far the largest end-use sector. Yet, these materials have been under environmental scrutiny for some time, with the fossil origin of plastics, biodegradability, single-use applications and plastic pollution being major areas of criticism. For these reasons, more sustainable solutions are being investigated. To address the issue of fossil resources, biomass-derived 2,5-furandicarboxylic acid (FDCA) is seen as having potential for the packaging market as it is the precursor of poly(ethylene furanoate) (PEF), which in turn is considered a suitable substitute for poly(ethylene terephthalate) (PET). FDCA as the precursor of a potentially more sustainable alternative to PET is emphasized, especially by industry experts, who even refer to it as a “sleeping giant”. Nevertheless, FDCA-based products have not yet made it to the market on a commercial scale, and efforts in this area currently don’t go much beyond R&D activities. Thus, this study attempts to determine how this potential attributed to FDCA might be unfolded in the future, and what challenges and opportunities might be expected along the way. For this purpose, 42 experts from different areas along the potential value chain of FDCA/PEF participated in a backcasting workshop and were surveyed about their future visions regarding the utilization of this molecule. The results show that academics and practitioners see great potential for FDCA-based products in the future, particularly as a replacement for PET. Economic aspects, such as costs, but also challenges in production and technology development are mentioned as the main barriers to FDCA market introduction. Interestingly, experts from FDCA synthesis and material development mainly refer to market applications for FDCA in their vision of the future. In turn, the future vision of FDCA application experts mainly covers developments in the areas of production, technology, and research, as well as increased environmental sustainability. To overcome these barriers, political regulations and the roles of society and consumers are considered to be the most important factors. These results demonstrate the importance of cross-disciplinary collaboration among stakeholders and coordinated innovation and research activities along the entire value chain to develop a shared vision for the future of FDCA and, accordingly, to successfully bring FDCA-based products to the market. Subsequent research activities could contribute to more sustainable packaging solutions in the future by performing, for example, technology roadmapping techniques and sustainability assessments of FDCA product candidates.

description: When a probe qubit is coupled to a quantum register that represents a physical system, the probe qubit will exhibit a dynamical response only when it is resonant with a transition in the system. Using this principle, we propose a quantum algorithm for solving discrete mathematical problems based on the circuit model. Our algorithm has favorable scaling properties in solving some discrete mathematical problems.

A role of humic matter and ore oxidation in rheology of oil sand slurries and in bitumen extraction
Creators: name: Gutierrez, Leopoldo
Publisher: name: University of British Columbia
Year: 2013

description: Eight oil sands ores were tested in order to quantify the levels of humic acids in these samples through the alkali extraction test originally developed to determine the oxidation of bituminous metallurgical coals. The test gives a concentration of humic acids released from ores, which in combination with the measurement of the total organic carbon content in the alkali extracts provides a measure of ore/bitumen weathering. It was found that poor ores exhibited the highest tendency to leach large amounts of humic acids per gram of bitumen in the samples which was quantified using the absorbance at 520 nm obtained from the UV/visible spectra. The results of contact angle measurements of water on bitumen showed that bitumen became more hydrophilic as pH increased, and that the hydrophobicity of bitumen drastically decreased when the sample was artificially oxidized. Additionally, the results suggested that humic acids make bitumen hydrophilic only if they are part of the internal/surface bitumen structure. Slurries of good ores displayed higher yield stresses than slurries of poor ores. This result is explained by the higher bitumen concentration existing in slurries of good ores which leads to more aggregation. Additionally, it was shown that bitumen oxidation/hydrophobicity also affected the rheology of oil sands slurries which also explains that slurries of poor ores displayed lower cohesion/aggregation than slurries of good ores. Yield stress data agreed with data obtained from power draw measurements that showed that good processing ores required more power for mixing. Extraction data obtained from flotation experiments indicated that the role of humic acids naturally present in the ores was basically that of a depressant of bitumen since poor ores contained the highest proportion of humic acids per gram of bitumen. Overall, it is possible to assess the processability of oil sand ores by quantifying the occurrence of humic acids in the ores, and to correlate ore processability with the rheology of oil sands slurries. Although poor ores are characterized by lower viscosities and lower power requirements during mixing, the presence of humic acids in these ores and their depressing action also contribute to lower bitumen recoveries.
