subject: Cartilage Boundary Lubrication

description: Proteoglycan 4 (PRG4) is a mucin-like glycoprotein found in synovial fluid (SF) and at the articular cartilage surface, where it is required for joint lubrication and health. Hyaluronan (HA), a glycosaminoglycan polymer, is another SF constituent that contributes to SF’s viscosity and cartilage lubrication properties. PRG4 and HA function effectively as friction reducing boundary lubricants at a cartilage-cartilage interface, though both have been studied at other interfaces with varying results. PRG4 can exist in SF as disulfide-bonded multimers, a structurally determinant characteristic of mucins, which may be necessary for its cartilage adsorption and boundary lubricating ability. A recently developed full-length recombinant human PRG4 (rhPRG4) has demonstrated appropriate higher order structure, O-linked glycosylations, and boundary lubricating ability at the ocular surface. However, it remains unclear if this rhPRG4 is able to adsorb to and function as a cartilage boundary lubricant. The objectives of this thesis were to (1) determine the effect of different sliding interface materials on the lubricating ability of PRG4 and HA by measuring the kinetic coefficient of friction, (2i) assess the cartilage adsorption and boundary lubricating ability of disulfide-bonded PRG4 multimers and PRG4 monomers, (2ii) evaluate the cartilage boundary lubricating ability of PRG4 multimers and PRG4 monomers with HA, and (3) assess the cartilage adsorption of rhPRG4 and the in vitro cartilage boundary lubricating properties of rhPRG4, with and without HA. PRG4 demonstrated boundary lubricating function at both cartilage-cartilage and cartilage-glass interfaces, while HA demonstrated friction reducing ability only at the cartilage-cartilage interface. The inter-molecular disulfide-bonded multimeric structure of PRG4 was important for its ability to adsorb to a cartilage surface and function as a boundary lubricant. Finally, rhPRG4 demonstrated cartilage adsorption and boundary lubricating function, with and without HA, equivalent to native PRG4. Collectively, these results demonstrate the effectiveness of putative cartilage boundary lubricants can be affected by the counterface, contribute to a greater understanding of the molecular basis of articular cartilage boundary lubrication of PRG4, and provide the foundation and motivation for future clinical evaluation of rhPRG4 as a biotherapeutic treatment for osteoarthritis.

description: The well-known piezoelectric constitutive equations are applicable to piezoceramics driven by low to moderate fields and therefore representing linear behavior. However, these materials are also known for their ferroelectric and ferroelastic nonlinearities particularly when input fields exceed coercive strength. Such nonlinearities are caused mainly by micro-structural changes in the material known as domain switching. Therefore, a constitutive model that can accommodate the domain switching process can help capture the nonlinear behavior of the material. The past two decades have seen increasingly intensive activities in the attempt to build constitutive models to describe the piezoceramics nonlinearities. One of such models takes the advantage of existing linear constitutive equations. By decomposing the state variables into linear and internal components, the existing piezoelectric constitutive equations are augmented to include internal variables in describing the linear behavior while additional attention is devoted to dealing with the internal states pertinent to material's nonlinearities. The latter requires the modeling of the domain switching process. Together, the augmented linear constitutive equations and a domain switching model provide a complete nonlinear constitutive description. Although very successful in qualitatively capturing the polarization hysteresis and strain butterfly phenomena, a major shortcoming of this approach has been that it cannot match quantitatively with experimental data. The objective of this research is to establish a constitutive model for piezoceramics that can not only qualitatively capture the material's nonlinear behavior over a large loading range, but also quantitatively match key characteristics from experimental data. In doing so, we have made three major contributions: 1) we discovered a flaw in the augmentation of linear constitutive equations for the use of materials in nonlinear regime and proposed a correct form of augmentation; 2) we proposed new domain switching rules based on the observations from single crystal experimental data; and 3) in the pursuit of model accuracy with quantitative description, we proposed the use of creep experiments to capture key characteristics related to time-dependent and rate-dependent responses. A finite element approach is taken to carry out numerical modeling at the microscopic level. Experimental data available in literature have been used to help with model development and validation.

description: A Standard Model-like Higgs near 125 GeV in the MSSM requires multi-TeV stop masses, or a near-maximal contribution to its mass from stop mixing. We investigate the maximal mixing scenario, and in particular its prospects for being realized it in potentially realistic GUT models. We work out constraints on the possible GUT-scale soft terms, which we compare with what can be obtained from some well-known mechanisms of SUSY breaking mediation. Finally, we analyze two promising scenarios in detail, namely gaugino mediation and gravity mediation with non-universal Higgs masses.

description: Recently, writer-director John Carpenter’s work has been read increasingly through a philosophical lens, as evidenced by the works of scholars such as Dylan Trigg, Anna Powell, and Eugene Thacker. However, the critical material on Prince of Darkness (1987) remains somewhat limited, especially considering the film’s explicitly philosophical narrative and themes. This project takes up Darkness’s dealings with epistemophobia, defined broadly as the fear of knowledge, before revealing more nuanced and complex meanings therein. We also consider the film’s deconstruction of human subjectivity, engaging extensively with Trigg, Powell and Thacker’s work while also affording necessary space to horror writer H. P. Lovecraft, a seminal influence on Carpenter’s oeuvre. By reading Darkness within the context of both philosophy and literature, this thesis demonstrates that Carpenter’s cinema deeply interrelates with these other disciplines, necessitating acknowledgment of their connections. The concept of epistemophobia provides the project’s primary philosophical intervention: how does one extract knowledge from that which is horrifically unthinkable?

description: Abstract This work looks at the determinants of youth acceptance or decline of Human Immunodeficiency Virus (HIV) Voluntary Counselling and Testing (VCT) offered in Kumasi, Ghana. All data are primary, and were gathered from the field through questionnaire surveys, semi-structured in-depth interviews and observation. The determinants identified had socio-cultural, structural, economic, and spatio-temporal dimensions. Some of the socio-cultural barriers identified are stigma, fear, ignorance, suspicion, gossiping, silence, belief and gender of youth. The attitudes of healthcare providers, inadequate hospital staff, minimal political commitment, and less influential media campaigns were some of the structural barriers revealed. Poverty was the main economic barrier identified, whilst the architectural design of hospital, hospital codes, and the physical layout of VCT centre, constitute the major spatial-temporal barriers to VCT. The socio-cultural incentives to VCT revealed were belief of negativity, adequate social capital and gender. The structural incentives identified included the availability of free testing and treatment, and positive provider attitude. Recommendations such as intensive campaigning and education, creation of social network pages, free, anonymous and rapid testing, political commitment, and legal protection of seropositive people against discrimination are made.

description: This thesis examines the impact of strategic tools and their understanding on both team and individual levels within Mastodon C. A qualitative approach was chosen, consisting of interviews with the team members of Mastodon C to gain a better understanding of their familiarity and use of strategic tools. Through the analysis of the results, it was found that while some team members were familiar with certain strategic tools, there was room for improvement when it comes to their understanding and utilization of other tools. Recommendations were made based on the results of the interviews, in order to improve Mastodon C's strategic planning and make informed decisions for the company's future steps.

description: We perform a global linear perturbative analysis, and investigate the oscillation properties of relativistic, non-selfgravitating tori orbiting around neutron stars in the slow rotation limit approximation. Extending the work done in Schwarzschild and Kerr backgrounds, we consider the axisymmetric oscillations of vertically integrated tori in the Hartle-Thorne spacetime. The equilibrium models are constructed by selecting a number of different non-Keplerian distributions of specific angular momentum, allowing for disc sizes $L \sim 0.5 - 600$ gravitational radii. Our results, obtained after solving a global eigenvalue problem to compute the xisymmetric $p$-modes, indicate that such oscillation modes could account with most observed lower ($ν_L$) and upper ($ν_U$) high frequency quasi-periodic oscillations for Sco X-1, and for some Z sources and Atoll sources with $ν_L\ gtrsim 500$ Hz. However, when $ν_L \lesssim 500$ Hz, $p$-modes oscillations do not account for the linear relation $ν_U = A ν_L + B$, $B \neq 0$ between the upper and the lower high frequency quasi-periodic oscillations that are observed in neutron star low-mass X-ray binaries.

description: This thesis explores how a “prototypical” process of planning and designing school buildings in the Province of Alberta, Canada, has evolved since the implementation of new procedures in the early years 2000, and assesses how aspects related to the built environment have been addressed. This has been done by examining architectural drawings as well as data-based documents, by conducting interviews with specific architects and members of school administration, by distributing questionnaires to teachers, and by visiting three schools designed through this new approach. The literature review, looked into the most relevant architectural design principles used around the world to develop successful educational buildings, and the impact of design on the school environment and its users. This allowed, by comparison with the design principles for successful educational buildings, for the success of Alberta’s standardized design for new public schools to be evaluated, and to recommend necessary architectural adaptations that will benefit users and school planning processes in Alberta, and throughout the globe.

description: We study CP asymmetries in rare B decays within supersymmetry with a U(2)^3 flavour symmetry, motivated by the SUSY flavour and CP problems, the hierarchies in the Yukawa couplings and the absence so far of any direct evidence for SUSY. Even in the absence of flavour-blind phases, we find potentially sizable CP violating contributions to b -> s decay amplitudes. The effects in the mixing-induced CP asymmetries in B ->phi K(S) and B -> eta' K(S), angular CP asymmetries in B -> K* mu+ mu- and the direct CP asymmetry in B -> X(s) gamma can be in the region to be probed by LHCb and next generation B factories. At the same time, these effects in B decays are compatible with CP violating contributions to meson mixing, including a non-standard B(s) mixing phase hinted by current tensions in the CKM fit mostly between S(psi K(S)), epsilon(K) and Delta M(B(s))/Delta M(B(d)).

description: Serious mental disorders (schizophrenia, bipolar disorder and major depressive disorder (MDD)) have been associated with an excess risk of mortality. However, most datasets used to study these associations have been limited by small sample sizes, use of specialized clinical samples, and few covariates recorded, thereby impeding proper assessments of mortality risks. Electronic medical records databases such as The Health Improvement Network (THIN) directly address these limitations by offering a large primary care population for study, with inclusion of numerous clinically-relevant covariate data over a long follow-up period. To date, THIN has not been used to study mortality in serious mental illness. As such, this thesis had the following objectives: i) estimate annual prevalence of serious mental illness; ii) determine the covariate-adjusted and unadjusted risk of all-cause mortality in serious mental illness and iii) demonstrate the feasibility of using THIN to study the excess mortality associated with serious mental illness. THIN was used to define schizophrenia, bipolar disorder and MDD cohorts between the years of 1986-2012, where annual prevalence estimates in 2012 were 0.23%, 0.26% and 9.49% respectively. Survival analyses adjusted for important covariates revealed that in the schizophrenia cohort (n=6,056), the risk of all-cause mortality was more than double (HR=2.36, 95%CI: 1.83 – 3.04) the risk in the referent cohort (n=6,137,760). Similarly, patients with bipolar disorder (n=9,425) were found to have twice the risk of all-cause mortality (HR=2.00, 95%CI: 1.70-2.34) compared to the referent cohort (n=6,131,373). Patients with MDD (n=405,866) were also found to have a significantly greater risk of all-cause mortality (HR=1.28, 95%CI: 1.21-1.36) compared to the referent cohort (n=5,337,098). Annual prevalence estimates for schizophrenia and MDD were similar to previous reports, but estimates were lower for bipolar disorder, possibly due to issues in correctly identifying these patients in primary care. This study was the first to confirm the excess mortality associated with serious mental disorders using THIN, highlighting that studying mortality among patients with serious mental illness is feasible in THIN. As such, the work presented in this thesis can pave the way for future research using THIN to improve the health of patients with serious mental disorders.

description: Graphene is an attractive material for spintronics due to theoretical predictions of long spin lifetimes arising from low spin-orbit and hyperfine couplings. In experiments, however, spin lifetimes in single layer graphene (SLG) measured via Hanle effects are much shorter than expected theoretically. Thus, the origin of spin relaxation in SLG is a major issue for graphene spintronics. Despite extensive theoretical and experimental work addressing this question, there is still little clarity on the microscopic origin of spin relaxation. By using organic ligand-bound nanoparticles as charge reservoirs to tune mobility between 2700 and 12000 cm2/Vs, we successfully isolate the effect of charged impurity scattering on spin relaxation in SLG. Our results demonstrate that while charged impurities can greatly affect mobility, the spin lifetimes are not affected by charged impurity scattering.

description: The CMB anisotropies in spherical 3-spaces with a non-trivial topology are analysed with a focus on lens and prism shaped fundamental cells. The conjecture is tested that well proportioned spaces lead to a suppression of large-scale anisotropies according to the observed cosmic microwave background (CMB). The focus is put on lens spaces L(p,q) which are supposed to be oddly proportioned. However, there are inhomogeneous lens spaces whose shape of the Voronoi domain depends on the position of the observer within the manifold. Such manifolds possess no fixed measure of well-proportioned and allow a predestined test of the well-proportioned conjecture. Topologies having the same Voronoi domain are shown to possess distinct CMB statistics which thus provide a counter-example to the well-proportioned conjecture. The CMB properties are analysed in terms of cyclic subgroups Z_p, and new point of view for the superior behaviour of the Poincaré dodecahedron is found.
Evaluating epidemiologic associations between occupational whole body vibration and Parkinson's disease
Creators: name: Harris, Margaret Anne
Publisher: name: University of British Columbia
Year: 2010

description: Parkinson’s disease is a chronic degenerative illness, the ultimate causes of which remain largely unknown. This thesis aims to test a new etiological hypothesis: that whole body vibration exposure may be associated with Parkinson’s disease. The thesis comprises three studies relevant to a test of this hypothesis. The first study concerns the methods by which cases of Parkinson’s disease can be defined at a population level and the prevalence of Parkinson’s disease in British Columbia. Levodopa (a drug typically used for Parkinson’s treatment) was increasingly used by people without a Parkinson’s diagnosis between 1996 and 2005, with non-Parkinson’s users outnumbering physician diagnosed cases among women and those under the age of 65 in 2005. These changes in levodopa use could mean that relying on use of levodopa to define Parkinson’s disease cases will be less efficient. The second study developed a method for retrospectively assessing occupational whole body vibration from a detailed interview conducted in a case control sample. I combined self-reported exposure with estimates of vibration intensity (acceleration) derived from the literature to construct metrics of exposure. I concluded that three of the metrics (duration, most intense equipment exposure, and a dose calculation that combined intensity and duration in a cumulative measure after raising vibration acceleration values to the fourth power) captured sufficiently different aspects of occupational exposure for individual tests of their associations with Parkinson’s disease. The third study tested these associations using logistic regression. The metrics were categorized to enable the detection of nonlinear effects. Ever being occupationally exposed to whole body vibration was inversely associated with Parkinson’s disease, as was the lowest category of most intense equipment exposure. However, the highest values of most intense equipment exposure were associated with increased odds of Parkinson’s disease. Effects were strongest when exposures that occurred more recently than 20 years prior to diagnosis were excluded. A protective effect of low intensity vibration could be due to correlation with a confounding protective factor such as physical activity, while an increased risk associated with high intensity exposures could be due to mechanical stress imposed by the repetitive shocks incurred.

We also review f(T) theories, a different approach to modified gravity consisting in a deformation of the teleparallel equivalent of General Relativity. We show some applications to cosmology and cosmic strings. As f(R)'s, f(T) theories are not exempted from additional degrees of freedom; we also discuss this still open issue.

description: The problem guiding this doctoral research is that present-day science education does not always promote the action or ‘citizenry’ required to address local and global environmental problems. The question guiding this research, presented across three manuscripts, is how can environmental identity development be fostered in students learning within the classroom context? A theoretical review of the environmental identity literature revealed that multiple interpretations of environmental identity exist, which varied in the significance given to the social context within which identities develop. Social network analysis revealed that Clayton's (2003) interpretation of environmental identity, emphasizing emotional connections to nature and the physical context, has greatly influenced the research. However, this interpretation of environmental identity may be inappropriate for the highly social classroom context. A case study of an in-school sustainability program called Trash to Treasure (T2T) was used to qualitatively explore environmental identity development in students. Participant observations, group interviews, reflective journals, and student artifacts from 35 focus participants were collected. Eight dimensions of student environmental identity development were identified during the T2T program: the opportunity to be an environmental actor with peers, awareness of environmental threat, emotion, personal meaning, social and self-recognition for environmental action, perceived individual agency, and changed behaviour across social contexts. A framework is offered to represent how these dimensions might interact if the desired outcome is fostering a student’s capacity to take environmental action learned at school into other social contexts. The key element appears to be designing activities that provide time and space for reflection on environmental identity actions. A second case study focused more closely on how three students reflected on the T2T experiences. Inquiry reflection, emotional reflection and critical reflection all contributed to environmental identity, however critical self-reflection was notably absent. Five design strategies are offered to support educators: (1) class participation in citizen science to extend the reach of environmental action beyond school, (2) extending inquiry reflection to include problem solving, (3) creating ‘safe learning spaces’ for emotional reflection and identity navigation, (4) extending critical reflection/thinking to include critical self-reflection, and (5) supporting the ‘thickening’ of student environmental identities beyond the classroom.

description: Long baseline laser interferometers used for gravitational wave detection have proven to be very complicated to control. In order to have sufficient sensitivity to astrophysical gravitational waves, a set of multiple coupled optical cavities comprising the interferometer must be brought into resonance with the laser field. A set of multi-input, multi-output servos then lock these cavities into place via feedback control. This procedure, known as lock acquisition, has proven to be a vexing problem and has reduced greatly the reliability and duty factor of the past generation of laser interferometers. In this article, we describe a technique for bringing the interferometer from an uncontrolled state into resonance by using harmonically related external fields to provide a deterministic hierarchical control. This technique reduces the effect of the external seismic disturbances by four orders of magnitude and promises to greatly enhance the stability and reliability of the current generation of gravitational wave detector. The possibility for using multi-color techniques to overcome current quantum and thermal noise limits is also discussed.

description: This thesis deals with the creation of campus culture in one of Canada’s first universities to be formed as a co-educational university. Using predominantly primary source material derived from university, student, alumni, professor, and administrative accessions at the University of Alberta, this thesis explores how men and women managed to create a campus culture at a time when women were just being introduced to college campuses in Canada. Certain difficulties such as maintaining respectability while in close proximity to men, finding a place for women on campus, and exploring roles for educated women in Canadian society are some of the challenges the female students faced while trying to create an educational environment that was both instructive and meaningful. The solution for the women at the University of Alberta was the formation of the Wauneita Society. The Wauneitas gave women a voice and a presence on campus that as a distinct minority, they would have otherwise been without.
School failed coyote so fox made a new school : Indigenous Okanagan knowledge transforms educational pedagogy

Year: 2010

description: This project examines how Indigenous Okanagan knowledge embedded in traditional stories, life histories and people’s practices, responsibilities and relationships are relevant and applicable to current and future Okanagan people’s educational and cultural aspirations. Okanagan language proficiency, cultural and territorial knowledge and practice, provincial curriculum and world knowledge are all important elements in creating Okanagan identity. The focus of this thesis is to identify, understand and theorise the transforming potential of Okanagan pedagogy through the development of an Okanagan cultural and language immersion school where language and cultural knowledge recovery are key elements, and express a new and current understanding, through a Sqilxw-Okanagan, children centred, extended family pedagogical approach and curriculum structure for current application in schooling projects and communities. Indigenous and world knowledge that improves, complements, and is compatible with evolving Okanagan knowledge and practice is included to generate an interconnected web; a convergence that may be useful in Okanagan, Indigenous and world educational contexts.

description: Inflammatory bowel disease (IBD) is a heterogeneous group of chronic, relapsing inflammatory gastrointestinal diseases for which there is no cure. Many models of IBD exist, owing to the complex disease pathophysiology. Although immunosuppressants are mainstay treatments, antibiotics are frequently prescribed to decrease harmful bacteria, which can exacerbate immune responses. Azithromycin is a macrolide antibiotic with immunomodulatory functions that has been extensively studied in the airways, but few have examined its role in IBD. This project investigated several clinical, pathological, and immunomodulatory effects of azithromycin in a murine dextran sulfate sodium model of colitis. Azithromycin substantially mitigated clinical disease presentation, as assessed by animal behaviour, weight change, and gross pathology. However, these effects were not reflected on a microscopic, hematologic, or biochemical level, and no mechanism was found to explain them. The results highlight the importance of clinical assessment as a tool to determine therapeutic efficacy in colitis research.

description: Hand function after stroke is clinically assessed by using observation and coarse, ordinal scales to classify impairment severity. Researchers have postulated that these assessment tools may be unable to detect small but clinically relevant differences in impairment. The purpose of this study was to develop an assessment tool, the Dextrometer, that accurately measures and identifies aberrant multi-digit force production patterns produced by stroke patients. To address this goal, acute stroke patients were asked to produce maximum voluntary force with their stroke-affected and unaffected hands in both the extension and flexion directions while forces were recorded from all digits. The results show that the Dextrometer successfully identified unique patterns of digit interactions in the affected hand and also distinguished between different levels of impairment. This study provides justification for the use of the Dextrometer and force production measures for discriminating impairments in hand function.

description: In this paper we present simulated solar coronal X-ray observations to verify the sensitivity of a new hypothetical instrument design. These simulations are folded through this X-ray spectrometer having a moderate size circular field of view of 1.6 degrees. This SCXM (Solar Coronal X-ray Mapper) is designed to compose of a single pixel silicon PIN detector equipped with a single reflection double frustum X-ray optics. A moderate FoV would enable a morphological study of the expanded X-ray emission from the solar corona during a high activity of the Sun. The main scientific task of SCXM would be the mapping of the coronal X-ray emission, i.e. to resolve the radial distribution of the X-ray surface brightness around the Sun. These kind of off-limb observations would help to interpret the coronal plasma diagnostics as a function of the elongation angle. Direct solar full disc observations could be also performed with SCXM. In this work we have applied real solar coronal X-ray data obtained by the SMART-1 XSM (X-ray Solar Monitor) to simulate on-solar observations at different flux levels to derive full disc sensitivity and performance of SCXM. A challenging attempt for SCXM would also be to distinguish the X-ray spectrum of the decaying axions around the Sun. These axions are assumed to be created as side products of fusion reactions in the core of the Sun. These axions are predicted to be gravitationally trapped to orbit the Sun forming a halo-like X-ray emitting object. No signature of an axion X-ray emission around the Sun has been observed to this day. This simple X-ray spectrometer with an optical concentrator would be an inexpensive instrument with low mass and telemetry budgets compared with more accurate X-ray instruments of imaging capability. Hence SCXM would be an advanced choice as an auxiliary instrument for solar coronal X-ray observations.

description: Spatially-explicit capture-recapture (SCR) methods can be used for estimating animal density and testing biogeographic hypotheses about the influence of landscape heterogeneity on animal space use. I used SCR to estimate the density of grizzly bears inhabiting the tundra of the central Canadian Arctic and extended the SCR framework to estimate their multi-scale habitat selection in relation to the spatiotemporal variation of food sources. Grizzly bear density was estimated to be 4.56 bears/1,000km2, which is slightly higher than estimates from 15-20 years ago. Berries and the spatial distribution of migratory caribou had the largest effect on the large scale selection patterns of bears. Food abundance had less of an effect on the resource selection of grizzlies within their home ranges. The results of this thesis indicate that grizzly bear density in the tundra is dependent upon food sources, with other factors such as intraspecific competition governing finer-scale selection patterns.

description: Anterior cruciate ligament (ACL) tears increase the risk of osteoarthritis (OA) leading to degradation of cartilage and bone. While the contribution of bone in OA development is unclear, evidence suggests that bone changes accompany cartilage degradation. This study aims to explore the relationship between subchondral compact bone thickness and cartilage thickness by comparing women with ACL reconstructions (ACLR) 5 years post-injury to uninjured controls using magnetic resonance imaging (MRI) and high resolution peripheral quantitative computed tomography (HR-pQCT). We found that ACLR knees had thicker subchondral compact bone in the lateral femur than contralateral knees (12.9% thicker, p=0.013) and injured participants had more subchondral compact bone thickness side-to-side variation than controls (>6.4 times increase, p<0.004). We did not detect cartilage thickness differences (p>0.06). This study demonstrates that subchondral compact bone thickness differences are prominent following injury, as measured by HR-pQCT, which may provide novel insight into OA pathogenesis.

description: In a recent letter [Chatterjee R, Mohanty P K, and Basu A, 2011 {\em J. Stat. Mech.} L05001], it was claimed that a four-state predator-prey (4SPP) model exhibits critical behavior distinct from that of directed percolation (DP). In this Letter, we show that the 4SPP in fact belongs to the DP universality class.

description: Quantum information science is at the interface of physics and information theory, with applications including quantum computing and communication. Within this science, a resource theory is a detailed study of a particular class of physical processes, under which the possible state transitions are restricted. Given any initial physical state, the possible final states are also restricted. Initial states with a wealth of possible final states can then be considered more valuable than less versatile initial states, leading to a notion of "resourcefulness" of states. The broad goals of a resource theory include (1) to identify, characterize, and quantify resources; (2) to find an efficient way to determine whether an arbitrary instance of resource conversion is possible; and (3) to relate practical applications to resource conversion. In this thesis, we will take the resource-theoretic approach to understanding thermodynamics. The mathematical methods used in this work will enable us to also develop resource theories for measurement uncertainty and reference frames; in fact, the resource-theoretic treatment of thermodynamics is a combination of these two. Our approach is based on a model called thermal operations, applicable on individual quantum-mechanical systems out of thermal equilibrium. We study this model in detail, resulting in a better understanding of the resource of thermal inequilibrium. In a simplified version of the model where quantum coherence is neglected, we find that the conditions for state transitions are already more complex than the classical second law of thermodynamics. We extend the model to quantum systems controlled by classical circuitry. We also extend it to incorporate quantum coherence in the low-temperature limit. Measurement uncertainty is an important element in quantum mechanics. But its current understanding is through particular measures of uncertainty, such as the variance. We apply the resource theory approach to develop a measure-independent formalism for uncertainty, even in the case where the measurement is on part of a composite system with quantum correlations. Under physical processes restricted by some symmetry (e.g. rotational symmetry), asymmetric states act as resourceful reference frames. In this resource theory, we find the rate at which large quantities of resources can be interconverted through measurements.

description: The goal of this thesis is to attempt to provide a classification of multidimensional per sistence. We present two main attacks on this problem. First, we examine the relationship between multidimensional persistence and one dimensional persistence. Second, we attempt to classify the module by a certain linear map obtained by taking a free resolution of the multipersistence module. In both cases, we examine the pro’s and con’s of the approach by providing an illuminating example.
