description: Fluorescence based biosensors, a methodology used to measure gluten concentrations, stillpresent challenges in the quality of the measurements. To overcome these limitations animprovement in the sol-gel based optical filter is proposed. In this thesis, we present thedevelopment of an optical filter employing a surfactant. Optical quality was explored basedon homogeneity and transparency, absorbance values and repeatability of measurements. Theaddition of surfactant showed better repeatability measurements over optical filters with nosurfactant. Additionally, we present a simplified gluten detection assay with the use of aquencher molecule. Instead of using a fluorophore as a signal generation molecule, a quencher molecule is used to absorb the light. For this approach, gliadin conjugate with the quencher molecule is developed. This complex is used as competitive reagent to bind to the unbound aptamer after it was incubated with the sample. We measured absorbance values leading to calculation of gluten concentration in the sample.

description: In this survey paper, we discuss the problem of characterizing the critical sets of bounded analytic functions in the unit disk of the complex plane. This problem is closely related to the Berger-Nirenberg problem in differential geometry as well as to the problem of describing the zero sets of functions in Bergman spaces. It turns out that for any non-constant bounded analytic function in the unit disk there is always a (essentially) unique "maximal" Blaschke product with the same critical points. These maximal Blaschke products have remarkable properties simliar to those of Bergman space inner functions and they provide a natural generalization of the class of finite Blaschke products.

description: This work is devoted to giving a geometric framework for describing higher-order non-autonomous mechanical systems. The starting point is to extend the Lagrangian-Hamiltonian unified formalism of Skinner and Rusk for these kinds of systems, generalizing previous developments for higher-order autonomous mechanical systems and first-order non-autonomous mechanical systems. Then, we use this unified formulation to derive the standard Lagrangian and Hamiltonian formalisms, including the Legendre-Ostrogradsky map and the Euler-Lagrange and the Hamilton equations, both for regular and singular systems. As applications of our model, two examples of regular and singular physical systems are studied.

The Role of Proteoglycan 4 in the Rheology of Synovial Fluid

description: The free motion of joints in the body is rendered safe by the biomechanical properties of articular cartilage and synovial fluid (SF). Cartilage is an elastic tissue capable of withstanding large compressive forces, whereas SF is a lubricating fluid with remarkable viscoelastic properties. The high molecular weight polysaccharide hyaluronan (HA) and the mucin-like glycoprotein proteoglycan 4 (PRG4 or lubricin) are crucial macromolecules in SF that lubricate cartilage synergistically; however, there is an ongoing debate on how their interactions in influence SF rheology. This thesis examined the relationship between the microstructure and the rheological properties of physiologically relevant formulations of HA and recombinant human PRG4 (rhPRG4) to elucidate on the interactions between them in SF. A succinct fractional framework was adapted to effectively describe the linear and nonlinear viscoelastic behaviour of HA+rhPRG4 solutions at both macroscopic and microscopic length scales. It was found that the bulk rheology of HA solutions increased with the addition of rhPRG4 in a dose-dependent manner, but the extent of these enhancements depended on the degree of rhPRG4 glycosylation. Afterwards, an optical tweezers-based methodology was modified using our fractional framework to characterize the rheology of the microstructure in our solutions. Contrary to previous studies, no evidence was found of a favourable physical interaction between HA and rhPRG4 which could functionally alter the macroscopic rheology of the solutions. At the microscopic level, rhPRG4 was shown to cluster into stiff gel-like aggregates that did not interact with the surrounding continuous phase of HA polymers. Furthermore, the interfacial adsorption of rhPRG4 molecules at the air-water interface of the rotational rheometer was shown to play a considerable effect in the interpretation of macrorheological data. Finally, clinically relevant non-ionic surfactants used in the stabilization of rhPRG4 formulations were shown to both suppress the interfacial adsorption of rhPRG4 in rotational rheometers and disrupt the aggregation behaviour of rhPRG4 in the bulk. Taken together, these results suggest that, in SF and potential HA+PRG4 biotherapeutic supplements designed for osteoarthritic joints, HA governs the bulk rheology of the fluid whereas the impact of PRG4 is restricted to its tribological performance.

description: In this paper, we develop a general existence theory for properly embedded minimal surfaces with free boundary in any compact Riemannian 3-manifold $M$ with boundary $\partial M$. The main feature of our result is that no convexity assumption is required on $\partial M$. Our proof uses a variant of the min-max construction first considered by Almgren and Pitts. Recently, Colding-De Lellis gave a simplified proof of the interior regularity and here, we prove the boundary regularity of the limiting embedded minimal surfaces at their free boundaries. In addition, we define a topological invariant, the filling genus, for compact 3-manifolds with boundary and show that we can bound the genus of the minimal surface constructed above in terms of the filling genus of the ambient manifold $M$.

Application of Machine Learning in Prostate Cancer External Beam Radiation Therapy to Improve Biochemical Failure-Free Survival Prediction
Creators: name: Sun, Lingyue

description: Curative external beam radiation therapy (EBRT) is a common treatment option for localized prostate cancer. The reported biochemical failure-free survival (BFFS) for prostate cancer patients post-EBRT varies significantly. The current, widely implemented clinical models that are used to predict treatment outcome for these patients have limited reliability. This thesis aims to examine the possible sources of influence on BFFS and improve EBRT treatment outcome prediction in terms of BFFS in particular using machine learning (ML) algorithms.Radiotherapy clinical trial protocols are adopted by different institutions due to their promising outcome(s) and/or superior efficiency. In this thesis, we first quantified the plan quality differences across four institutions in Alberta for PROstate Fractionated Irradiation Trial (PROFIT) plans. Despite the common guiding protocol, we observed statistically significant differences in dosimetric parameters between institutions; however, outcome modeling suggested such differences were of minimal clinical consequence.There is a need for more detailed understanding of the relationships between EBRT treatment planning and treatment delivery-related features and tumor control outcomes. We investigated the EBRT-related features that may be prognostic of BFFS using a random survival forest model. We found that the clinical target volume D99, pelvic irradiation, IGRT frequency, and planning target volume V98 were prognostic in addition to a set of tumor features.We then investigated whether ML-based models that incorporated additional EBRT treatment planning and delivery related features could perform better than the clinical models that were exclusively based on patient demographic and tumor features. We found that the two ML-based models outperformed the two clinical models on both the training and validation datasets, although all models’ performances deteriorated against the validation dataset.To further improve BFFS prediction, we investigated whether adding dosiomic features, which contains spatial information about the planned 3D dose distribution, could enhance the model performance. We did find improvement, and such improvement although relatively small was maintained when the model was validated with patients from other institutions. Additionally, we evaluated the impact of dose calculation variations on dosiomic features and found that most dosiomic features were stable against variations in dose calculation algorithms, versions, and dose grid.
Spin- and angle-resolved photoemission spectroscopy on unconventional superconductor strontium ruthenate
Creators: name: Veenstra, Christian Neil
Publisher: name: University of British Columbia
Year: 2013

description: This thesis represents two bodies of work: a detailed look at what angle- resolved photoemission spectroscopy (ARPES) measures, as well as ARPES and circularly polarized photon spin- and angle-resolved photoemission spectroscopy (CPS-ARPES) measurements on the unconventional superconductor Sr₂RuO₄. In the first part I present a study of both established methods of ARPES analysis and some new variations on model spectral functions. This modelling was done in a realistic regime, yet far from the limits often assumed. Away from these limits I show that any "effective coupling" inferred from quasiparticle renormalizations differs drastically and unpredictably from the true coupling. Conversely, I show that perturbation theory retains good predictive power where expected, that the momentum dependence of the self-energy can be revealed via the relationship between velocity renormalization and quasiparticle strength, and that it is often possible to infer the self-energy and bare electronic structure through lineshape analysis. In the second part I present experimental ARPES and CPS-ARPES data on Sr₂RuO₄. Newly discovered and unexplained ARPES features are characterized and compared with a variety of different possible structural distortions through bulk and slab local-density approximation (LDA) band structure calculations. I thereby rule out phases driven by electronic interaction, such as Dirac- or Rashba-type surface states, and instead find that there exists a progressive structural modulation whereby both the surface and (at a minimum) sub-surface layers exhibit a (√2 x √2)R45° reconstruction. Through CPS-ARPES on Sr₂RuO₄ I also directly demonstrate that the effects of spin-orbit (SO) coupling are not limited to a modification of the band structure, but fundamentally entangle the spin and spatial parts of the wave-function. This must drive the superconducting state in Sr₂RuO₄ to be even more unconventional than is generally assumed, with mixing between singlet and triplet states that varies around the Fermi surface, and thereby offers a possible resolution to a number of experiments that clash with the categorization of Sr₂RuO₄ as a hallmark spin-triplet chiral p-wave superconductor.

description: We present the results of a visual search for galaxy-scale gravitational lenses in nearly 7 square degrees of Hubble Space Telescope (HST) images. The dataset comprises the whole imaging data ever taken with the Advanced Camera for Surveys (ACS) in the filter F814W (I-band) up to August 31st, 2011, i.e. 6.03 square degrees excluding the field of the Cosmic Evolution Survey (COSMOS) which has been the subject of a separate visual search. In addition, we have searched for lenses in the whole Wide Field Camera 3 (WFC3) near-IR imaging dataset in all filters (1.01 square degrees) up to the same date. Our primary goal is to provide a sample of lenses with a broad range of different morphologies and lens-source brightness contrast in order estimate a lower limit to the number of galaxy-scale strong lenses in the future Euclid survey in its VIS band. Our criteria to select lenses are purely morphological as we do not use any colour or redshift information.The final candidate selection is very conservative hence leading to a nearly pure but incomplete sample. We find 49 new lens candidates: 40 in the ACS images and 9 in the WFC3 images. Out of these, 16 candidates are secure lenses owing to their striking morphology, 21 more are very good candidates, and 12 more have morphologies compatible with gravitational lensing but also compatible with other astrophysical objects. It is therefore insensitive to cosmic variance and allows to estimate the number of galaxy-scale strong lenses on the sky for a putative survey depth, which is the main result of the present work. Because of the incompleteness of the sample, the estimated lensing rates should be taken as lower limits. Using these, we anticipate that a 15 000 square degrees space survey such as Euclid will find at least 60 000 galaxy-scale strong lenses down to a limiting AB magnitude of I = 24.5 (10-sigma) or I = 25.8 (3-sigma).

description: Exhuming Animacy is a creative writing thesis about the lives of cephalopods, stone, bacteria, fungi, and other collectives of more-than-human beings. It is also a novel about the ecological implications of climate change, a crisis that encapsulates a planet’s-worth of disparate species and materials. Through these various perspectives, the interweaving narratives amalgamate past and present systems of human exploitation, instill a sense of shared experience amid ecological catastrophe, and depict moments of surreal transformation, all of which are fundamental facets of the unmaking of a planetary ecosystem. These stories also reflect the vital importance of so-called ‘alien’ ways of being, demonstrating how the inertia of unjust and unequal arrangements of power cannot eliminate productive, embodied connection, no matter how increasingly predetermined an apocalyptic end might seem. Such forms of storytelling might intercede in this urgent moment of climate response by instilling a sense of possibility. Speculative fiction is a means of thinking beyond the destructive arrangements driving the climate crisis, and a means of gesturing toward ever-present opportunities for collective transformation—an absolute necessity amid environmental collapse. Through these acts of creative speculation, possibility and opportunity can help instill a vital sense of hope, which might be used to theorize and enact ways of being that better reflect the ecological principles that give rise to Earth.

As a consequence the projection of a generic grafting ray to moduli space is dense. We also show that the set of points in Teichmüller space obtained by integer (2π-) graftings on any hyperbolic surface projects to a dense set, which implies that complex projective surfaces with any fixed Fuchsian holonomy are dense in moduli space.

We report that lasing of the bright negative-index mode is possible if the higher-Q dark mode is discriminated by gain, spatially or spectrally. The nonlinear competition during the transient phase is followed by steady-state emission where bright and dark modes can coexist. We analyze the influence of pump intensity and polarization and explore methods for mode control.

description: Mesenchymal stem cells (MSCs) have attracted research interest due to their ability to induce tissue repair and reduce inflammation. More recently, their therapeutic benefits have been attributed to small membrane bound vesicles called extracellular vesicles (EVs) that they release. The implantation of MSC-EVs offers significant advantages over the implantation of viable MSCs. Their nonliving nature eliminates many of the safety concerns related to cell therapies and enables them to be stored and transported more efficiently. There is a significant need to develop clinically applicable bioprocesses that can produce large numbers of therapeutically relevant MSC-EVs. This involves the translation of small-scale studies to large scale processes, which is limited by considerations such as the medium and platform in which the cells are cultured. Due to the novelty of the EV field, current research in this area is very limited, and thus the goal of this thesis was to evaluate the efficacy of producing MSC-EVs in a clinically relevant medium, and to gain insight into the impact of culture parameters needed for the scale-up of MSC-EVs. This thesis demonstrated, for the first time, that functional MSC-EVs could be produced using a clinically relevant serum-free culture medium for the applications of articular cartilage repair, cerebral ischemia, and intracranial aneurysm repair. Further, it was found that functional MSC-EVs could be produced in scalable stirred suspension bioreactors. These studies were among the first to evaluate the use of such a platform for EV production and were the first to present a scalable model for EV production specifically for the applications of articular cartilage repair and cerebral ischemia. In addition, the culture of MSCs at physiological oxygen conditions was evaluated and found to enhance their angiogenic potential, without damaging physiological function, in the application of cerebral ischemia. Finally, important considerations relevant to the upstream production of MSC-EVs were studied, including the confluence of cultured MSCs and the medium in which the EVs were isolated. This work enabled a proposed workflow for producing EVs in serum-free medium and will contribute highly to the development of clinically applicable bioprocesses aimed at producing MSC-EVs for applications in regenerative medicine.

description: It is well known that an information-rich environment needs to be developed where travelers and transit users have all the comprehensive and accurate information on travel options. The need is to capture, synthesize and deliver real time and up-to-date information, that is not only vehicle or infrastructure based but also environmentally relevant, that also supports building a transportation system that promotes environmental improvements. This work, Intelligent Transportation Application for Smarter and Greener Commute, gives all the useful and relevant pieces of information that the commuters seek, before starting their commute [travel time, cost, route comfort, trip's green level (emissions caused), current traffic situation], displayed in a comparative manner for all travel modes. Observed incidents can be reported and also searched, by commuters. Additionally, the work provides green performance rating to the user and the best mode suggestion for the journey entered by user, based on the relative importance of various journey characteristics, to the user. A sample of volunteer candidates were asked to use this in order to evaluate the work and a significant shift was seen in their travel mode choice from private to public transport. The idea to promote green transportation is also successfully executed through this work and the observations bolster this argument. With environmental concerns growing, the transportation system that a country needs should be one that improves the scene without affecting environment, something well implemented with this work. The impact of this work on future policy is that the information provided could also be used by the transportation agencies to see which areas are affected by incidents and restore normalcy at the earliest. Concisely speaking, smarter travel is guaranteed.

description: This project focused on studying photobleaching properties of erythrosine B in various environments. It was found that in an aqueous environment, at the same pH of 7.4, different photoproducts form, depending on the type of buffer used. The following aqueous solutions were tested: pure water, phosphate buffer, Tris and HEPES buffers. All of the aqueous systems examined yielded different results under photoirradiation, indicating that buffer selection is an important, often overlooked, parameter when investigating photo-biological systems. The photobleaching properties of erythrosine B coated onto solid substrates (silica and calcium sulfate) were explored in the presence of several additives, such as titanium dioxide and N-phenylglycine in order to control the rate of photobleaching. The former resulted in faster photobleaching rates, while the latter one in slower photobleaching rates. Lastly, the photobleaching of erythrosine B embedded in agarose gel was investigated as a thick gel, thin layer gel and dried out film. It was shown that titanium dioxide additives, both 325 mesh and nanoparticles, enhance the photobleaching rate of erythrosine B in the dried out film, whereas a tertiary amine additive promoted a dehalogenation reaction that converts EB to fluorescein, resulting in faintly yellow transparent films.

description: In this paper, we explore how the forthcoming generation of large-scale radio continuum surveys, with the inclusion of some degree of redshift information, can constrain cosmological parameters. By cross-matching these radio surveys with shallow optical to near-infrared surveys, we can essentially separate the source distribution into a low- and a high-redshift sample, thus providing a constraint on the evolution of cosmological parameters such as those related to dark energy. We examine two radio surveys, the Evolutionary Map of the Universe (EMU) and the Westerbork Observations of the Deep APERTIF Northern sky (WODAN). A crucial advantage is their combined potential to provide a deep, full-sky survey. The surveys used for the cross-identifications are SkyMapper and SDSS, for the southern and northern skies, respectively. We concentrate on the galaxy clustering angular power spectrum as our benchmark observable, and find that the possibility of including such low redshift information yields major improvements in the determination of cosmological parameters. With this approach, and provided a good knowledge of the galaxy bias evolution, we are able to put strict constraints on the dark energy parameters, i.e. w_0=-0.9+/-0.041 and w_a=-0.24+/-0.13, with type Ia supernovae and CMB priors (with a one-parameter bias in this case); this corresponds to a Figure of Merit (FoM) > 600, which is twice better than what is obtained by using only the cross-identified sources and greater than four time better than the case without any redshift information at all.

Atrial Electrophysiology and Arrhythmogenesis: Impacts of Diabetes Mellitus and Bruton's Tyrosine Kinase Inhibitors

description: Atrial fibrillation (AF) is the most common heart rhythm disorder and is highly prevalent in patients with diabetes mellitus (DM). Despite this, the mechanisms by which DM initiates and progresses AF are poorly understood. Accordingly, the initial aim of this thesis was to investigate atrial electrical remodeling in db/db mice, an obesogenic model of type 2 DM. Db/db mice were found to have increased susceptibility to AF in association with a unique pattern of atrial electrical remodeling. Glucagon-like peptide-1 (GLP-1) is an incretin hormone secreted by the gut that aids in glycemic control and has cardioprotective properties. Thus, additional studies were conducted to assess whether treating insulin-resistant db/db mice with GLP-1 or a GLP-1 mimetic (i.e., liraglutide) would prevent pathological atrial remodeling. In vivo studies showed that GLP-1 and liraglutide both significantly improved various aspects of atrial electrophysiology in the setting of DM. GLP-1 specifically improved atrial electrical remodeling in both intact atrial preparations and in atrial myocytes.The Bruton’s tyrosine kinase (BTK) inhibitor ibrutinib, used in the treatment of B-cell lymphomas, also leads to new-onset AF in patients; however, a thorough investigation of the effects of BTK inhibitors on atrial electrophysiology has not been conducted. BTK inhibition can modulate similar signaling pathways to insulin, suggesting the possibility of common mechanisms with DM. The second aim of this thesis was to measure the effects of the BTK inhibitors ibrutinib and acalabrutinib on atrial electrophysiology. Acute superfusion of ibrutinib on atrial preparations resulted in slowed conduction velocity and prolonged action potentials; moreover, ibrutinib had direct effects on ionic currents in atrial myocytes. However, the next-generation BTK inhibitor acalabrutinib had fewer effects on atrial electrophysiology both in isolated preparations and myocytes. These results suggest that ibrutinib causes AF via off-target effects. While BTK inhibitors were hypothesized to have similar effects on atrial electrophysiology to type 2 DM, these studies provide new insight into the distinct mechanisms that underlie AF mediated by type 2 DM and BTK inhibitors. Additionally, these data suggest GLP-1 can aid in the prevention of atrial electrical remodeling in type 2 DM.

description: Although a quantum computer is commonly modelled as a closed physical system, in practice the computer inevitably interacts with its environment and other systems. The aim of this thesis is to ascertain the advantages offered by controlled open-system phenomena and the limitations placed by unwanted system-environment interactions on quantum computation. This thesis is divided into two parts. The first part aims to ascertain whether a changing Hilbert-space inner product (IP), which is a controlled open-system phenomenon, enhances the power of quantum computers. The uniqueness of the IP associated to a quantum system has come under scrutiny following the advent of PT-symmetric quantum mechanics. A changing IP is valuable for quantum information processing applications; however, perfunctory use of this change can lead to counterfactual conclusions. In the first part of this thesis, we develop an operational framework for a changing IP, which is fully consistent with quantum mechanics. Next, to determine the utility of this change for computation, we construct a model of computation that uses IP changing operations along with unitary gates. We prove that the new model is equivalent to the quantum circuit model in terms of computational power. We also simulate the changing IP of a single qubit on Aspen-11 qubit and qutrit processors, and certify the quality of simulations. This experiment lays the foundation for simulating non-Hermitian dynamics on quantum computers. The second part of this thesis focuses on the effect of photon losses on certifiability of boson computers. Although improving the programmability of a boson computer is necessary for the demonstration of quantum advantage, it comes with the added challenge of increased photon losses. We develop a validation protocol that certifies the output of a lossy boson computer against an adversary with limited interferometer programmability. We also analyze the resource cost for validation with respect to two models of photon losses and show that validation becomes infeasible if each interferometer mode of the computer loses photons with a fixed probability. This work highlights the importance of accurately characterizing and suppressing photon losses in near-term boson computers.

description: We analyze the construction of conformal theories of gravity in the realm of teleparallel theories. We first present a family of conformal theories which are quadratic in the torsion tensor and are constructed out of the tetrad field and of a scalar field. For a particular value of a coupling constant, and in the gauge where the scalar field is restricted to assume a constant value, the theory reduces to the teleparallel equivalent of general relativity, and the tetrad field satisfies Einstein's equations. A second theory is formulated out of the tetrad field only, and is not equivalent to the usual Weyl Lagrangian. Therefore the latter is not the unique genuinely geometrical construction that yields a conformally invariant action. The teleparallel framework allows more possibilities for conformal theories of gravity.
description: 10 pages, no figures. We discuss the construction of the teleparallel version of the Weyl Lagrangian
