Integration of genomics into clinical care : methods for economic evaluation
Creators: name: Najafzadeh, Mehdi
Publisher: name: University of British Columbia
Year: 2012

description: Background: As genomic technologies become more affordable, the demand for having these data will increase. Decision-makers must anticipate the increasing influence of genomics on heath care systems and take into account the expectations of patients, the public, health care providers, and industry in this regard. This thesis demonstrates applications of several methods for evaluation of genomic technologies in medicine. Using four case studies, I have highlighted the advantages that each method can offer given the nature and scope of the research question in each case study. Objectives: My specific objectives in the case studies were: 1) To elicit the preferences of cancer patients as well as the public for a hypothetical, genetically-guided treatment for cancer (a discrete choice experiment ); 2) To estimate the relative importance of attributes which influence physicians’ decisions for using personalized medicine in their practice (a Best Worst Scaling choice experiment); 3) To evaluate the impact of three potential genomic/proteomic tests on the long term burden of COPD in Canada (a system dynamics model); 4) To measure the cost-effectiveness of adding a new molecular diagnostic test (DX) to the current diagnostic strategy for thyroid cancer (using a discrete event simulation). Methods: Through these case studies, I have demonstrated the particular advantages of using discrete choice experiment (DCE), best-worst scaling (BWS) experiment, system dynamics simulation, and discrete event simulation (DES) for evaluations of genomic technologies. Results: Using four case studies I exemplified the questions that emerge in the process of integrating genomics into clinical care. In addition to bridging the methodological gaps by incorporating several novel methods (BWS, dynamic systems, and DES), the selected case studies illustrated the practical issues regarding the integration of genomics into clinical care from the perspective of patients, the public, health care providers, and decisionmakers. Conclusion: Although the methods previously developed for health technology assessment can be applied to the evaluation of genomic technologies as well, methodological challenges in the evaluation of genomic applications entail utilizing more diverse and more sophisticated analytical tools.

description: Energy demand is still in the rising, as well as the environmental concerns related to the use of fossil fuels to meet it. Hence, the transition to alternative and renewable energy sources has become a priority. The production of tire pyrolysis oil (TPO) to eliminate waste tires and produce atmospheric distillates (IBP343°C) has great potential to reduce the amount of waste material and contribute to the energy transition. This work aimed to study the TPO atmospheric distillates upgrading capabilities using the hydrotreating (HDT) process and a new proprietary group of catalysts. First, catalyst Mo2C/Zeolite (P-1) was tested on a synthetic feedstock composed of model molecules emulating TPO atmospheric distillates. Results proved that the highest conversion of nitrogen and sulfur was achieved at 350°C and 0.3 h-1. Additionally, high conversion selectivity of the nitrogenated compounds was observed based on 100 % conversion of the quinoline model molecule. The previous experiment was followed by testing catalyst P-1 and another catalyst Mo2C/γ-Al2O3 (M-3) using a TPO naphtha/kero fraction (IBP-280°C). This test demonstrated that the acidity of the support was key to achieving higher levels of upgrading, nevertheless, it needed to be balanced with a higher hydrogenating function. Later, another set of experiments was performed using a TPO atmospheric distillates (IBP-343°C) fraction and catalysts M-3, P-2 and P-3, the last two with increasing hydrogenation functions. Results showed that catalyst P-3 reached sulfur and nitrogen levels conversion of 90% and 89%, respectively. Additionally, a study of the HDT products obtained in the last experiment was performed based on the distillation of the product into heavy naphtha (IBP-220°C) and diesel (220-343°C). Characterizing these cuts indicated that aromatic and polar compounds initially present in the heavy naphtha are easier to hydrogenate than those in the diesel fraction. Additionally, partial hydrogenation was observed in both cases due to the reduction of polyaromatic compounds and an increase in the tetralin family. Finally, a study on the reaction severity revealed that temperatures of 350°C, weight hourly space velocity of 0.1 h-1, pressure of 1,500 psig and Vol. H2/Oil of 1,200 are preferred for higher hydrogenation.

description: We suggest a new indicator of quantum chaos based on the logarithmic out-of-time-order correlator. On the one hand, this indicator correctly reproduces the average classical Lyapunov exponent in the semiclassical limit and directly links the definitions of quantum chaos and classical K-system. On the other hand, it can be analytically calculated using the replica trick and the Schwinger-Keldysh diagram technique on a $2n$-fold Keldysh contour. To illustrate this approach, we consider several one-dimensional systems, including the quantum cat map, and three paradigmatic large-$N$ models, including the Sachdev-Ye-Kitaev model. Furthermore, we find that correlations between replicas can reduce the magnitude of the Lyapunov exponent compared to estimates based on conventional out-of-time-order correlators.

description: We propose an analysis technique for the exceptional points (EPs) occurring in the discrete spectrum of open quantum systems (OQS), using a semi-infinite chain coupled to an endpoint impurity as a prototype. We outline our method to locate the EPs in OQS, further obtaining an eigenvalue expansion in the vicinity of the EPs that gives rise to characteristic exponents. We also report the precise number of EPs occurring in an OQS with a continuum described by a quadratic dispersion curve. In particular, the number of EPs occurring in a bare discrete Hamiltonian of dimension $n_\textrm{D}$ is given by $n_\textrm{D} (n_\textrm{D} - 1)$; if this discrete Hamiltonian is then coupled to continuum (or continua) to form an OQS, the interaction with the continuum generally produces an enlarged discrete solution space that includes a greater number of EPs, specifically $2^{n_\textrm{C}} (n_\textrm{C} + n_\textrm{D}) [2^{n_\textrm{C}} (n_\textrm{C} + n_\textrm{D}) - 1] $, in which $n_\textrm{C}$ is the number of (non-degenerate) continua to which the discrete sector is attached. Finally, we offer a heuristic quantum phase transition analogy for the emergence of the resonance (giving rise to irreversibility via exponential decay) in which the decay width plays the role of the order parameter; the associated critical exponent is then determined by the above eigenvalue expansion.

description: Reducing methane (CH4) emissions from anthropogenic activities is critical to climate change mitigation efforts. But there is still considerable uncertainty over the amount of fugitive CH4 emissions due to large-scale area sources and heterogeneous emission distributions. To improve the accuracy, a new hybrid method with high spatial and temporal resolutions is developed by combining optical remote sensing (ORS), computed tomography (CT), and inverse-dispersion modeling techniques. A multi-path scanning system is also developed using the horizontal radial plume mapping (HRPM) path geometry. The method adapts a Lagrangian stochastic (LS) dispersion model into CT reconstruction to derive emission distribution. Forward and backward LS models are developed and comprehensively compared to increase the model accuracy by supporting time-varying inputs. Controlled-release experiments of CH4 show this approach improves the accuracy by 5%-20% compared to the method using constant inputs. To address the challenges posed by limited path number and uneven sampling of HRPM path configuration, it uses a smooth algorithm of low third derivative (LTD) coupled with high-resolution grid division to improve the performance. By adapting the interpolation technique into CT reconstruction, a new minimal curvature (MC) algorithm based on the variational interpolation technique is formulated, showing significant improvement to the non-negative least squares (NNLS) algorithm and requiring approximately 65% computation time of LTD. To reconstruct realistic plume shape, a new Gaussian dispersion transformation algorithm is developed by introducing dispersion-related information. Numerical studies and controlled-release experiments show approximately 16% better performance on nearness than the NNLS and LTD algorithms. The combined method was evaluated through two controlled-release experiments of CH4, showing relative errors of only 2% and 3% compared to 5% - 175% for the single-path method. Field measurements of landfill CH4 emissions were first conducted in a scale-up site. Hotspots are successfully identified. The relative emission rate is 12.5%. Then, a test in a landfill biowindow area shows that more hotspots are successfully identified than the flux chamber method. The average emission rate over the site is 0.84 mg.m-2.s-1. The outcome of this research would bring broad application of the ORS-CT and inverse-dispersion techniques to other gases and sources.

description: Out-of-time-order correlators are widely used as an indicator of quantum chaos, but give false-positive quantum Lyapunov exponents for integrable systems with isolated saddle points. We propose an alternative indicator that fixes this drawback and retains all advantages of out-of-time-order correlators. In particular, the new indicator correctly predicts the average Lyapunov exponent and the Ehrenfest time in the semiclassical limit, can be calculated analytically using the replica trick, and satisfies the bound on chaos.

A new formulation of the local c-map based on the Hesse potential and special real coordinates is presented. Other recent developments include the Euclidean version of special geometry, and generalizations of special geometry to non-supersymmetric theories. As applications we disucss the proof that the local r-map and c-map preserve geodesic completeness, and the construction of four- and five-dimensional static solutions through dimensional reduction over time. The shared features of the real, complex and quaternionic version of special geometry are stressed throughout.

description: Our work presents a novel approach to shape optimization, with the twofold objective to improve the efficiency of global optimization algorithms while promoting the generation of high-quality designs during the optimization process free of geometrical anomalies. This is accomplished by reducing the number of the original design variables defining a new reduced subspace where the geometrical variance is maximized and modeling the underlying generative process of the data via probabilistic linear latent variable models such as factor analysis and probabilistic principal component analysis. We show that the data follows approximately a Gaussian distribution when the shape modification method is linear and the design variables are sampled uniformly at random, due to the direct application of the central limit theorem. The degree of anomalousness is measured in terms of Mahalanobis distance, and the paper demonstrates that abnormal designs tend to exhibit a high value of this metric. This enables the definition of a new optimization model where anomalous geometries are penalized and consequently avoided during the optimization loop. The procedure is demonstrated for hull shape optimization of the DTMB 5415 model, extensively used as an international benchmark for shape optimization problems. The global optimization routine is carried out using Bayesian optimization and the DIRECT algorithm. From the numerical results, the new framework improves the convergence of global optimization algorithms, while only designs with high-quality geometrical features are generated through the optimization routine thereby avoiding the wastage of precious computationally expensive simulations.

description: The explosive growth of the mobile Internet, and the increasing diversity of use cases that enabled by this, forces network providers to concurrently support a large variety of applications and services. This introduces the need to transform traditional closed, static and inelastic network infrastructures into open, scalable and elastic ecosystems. At the same time, new and emerging services impose enormous capacity requirements that exceed 1000 times the currently installed capacity. Furthermore, tenths of billions of end devices will require connectivity in a scalable and sustainable manner. To address these needs, a more efficient utilization of the radio frequency spectrum is necessary.

description: We have fabricated PbTiO$_{3}$/SrRuO$_{3}$ superlattices with ultra-thin SrRuO$_{3}$ layers. Due to the superlattice geometry, the samples show a large anisotropy in their electrical resistivity, which can be controlled by changing the thickness of the PbTiO$_{3}$ layers. Therefore, along the ferroelectric direction, SrRuO$_{3}$ layers can act as dielectric, rather than metallic, elements. We show that, by reducing the concentration of PbTiO$_{3}$, an increasingly important effect of polarization asymmetry due to compositional inversion symmetry breaking occurs. The results are significant as they represent a new class of ferroelectric superlattices, with a rich and complex phase diagram. By expanding our set of materials we are able to introduce new behaviors that can only occur when one of the materials is not a perovskite titanate. Here, compositional inversion symmetry breaking in bi-color superlattices, due to the combined variation of A and B site ions within the superlattice, is demonstrated using a combination of experimental measurements and first principles density functional theory.

Confronting global 21-cm signal with $\mathbb{Z}_3$ symmetric dark matter models

description: While the $\mathbb{Z}_3$ symmetric dark matter models have shown tremendous prospects in addressing a number of (astro-)particle physics problems, they can leave interesting imprints on cosmological observations as well. We consider two such promising models: semi-annihilating dark matter (SADM) and Co-SIMP $2\rightarrow 3$ interaction, and investigate their effects on the global 21-cm signal. SADM alone cannot address the EDGES dip but can perform better with the aid of an excess radio background, whereas Co-SIMP can naturally explain the EDGES absorption feature by virtue of an intrinsic cooling effect without invoking any such excess radiation. Hence, the latter model turns out to be a rare model within the domain of CDM, that uses leptophilic interaction to achieve the EDGES dip. Further, keeping in mind the ongoing debate between EDGES and SARAS 3 on the global 21-cm signal, we demonstrate that our chosen models can still remain viable in this context, even if the EDGES data requires reassessment in future. We then extend our investigation to possible reflections on the Dark Ages, followed by a consistency check with the CMB and BAO observations via Planck 2018(+BAO) datasets. This work thus presents a compelling case of exploring these interesting particle physics models in the light of different cosmological observations.

description: In an approach to noncommutative gauge theories, where the full noncommutative behavior is delimited by the presence of the UV and IR cutoffs, we consider the possibility of describing a system at a temperature T in a box of size L. Employing a specific form of UV/IR relationship inherent in such an approach of restrictive noncommutativity, we derive, for a given temperature T, an upper bound on the parameter of spacetime noncommutativity Lambda_NC ~ |theta|^{-1/2}. Considering such epochs in the very early universe which are expected to reflect spacetime noncommutativity to a quite degree, like the reheating stage after inflation, or believable pre-inflation radiation-dominated epochs, the best limits on Lambda_NC are obtained. We also demonstrate how the nature and size of the thermal system (for instance, the Hubble distance versus the future event horizon) can affect our bounds.

description: Various autonomous applications rely on recognizing specific known landmarks in their environment. For example, Simultaneous Localization And Mapping (SLAM) is an important technique that lays the foundation for many common tasks, such as navigation and long-term object tracking. This entails building a map on the go based on sensory inputs which are prone to accumulating errors. Recognizing landmarks in the environment plays a vital role in correcting these errors and further improving the accuracy of SLAM. The most popular choice of sensors for conducting SLAM today is optical sensors such as cameras or LiDAR sensors. These can use landmarks such as QR codes as a prerequisite. However, such sensors become unreliable in certain conditions, e.g., foggy, dusty, reflective, or glass-rich environments. Sonar has proven to be a viable alternative to manage such situations better. However, acoustic sensors also require a different type of landmark. In this paper, we put forward a method to detect the presence of bio-mimetic acoustic landmarks using support vector machines trained on the frequency bands of the reflecting acoustic echoes using an embedded real-time imaging sonar.

description: We have investigated the low-temperature local magnetic properties in the bulk of molten salt-flux (MSF) grown single crystals of the candidate odd-parity superconductor UTe2 by zero-field muon spin relaxation (muSR). In contrast to previous muSR studies of UTe2 single crystals grown by a chemical vapour transport (CVT) method, we find no evidence of magnetic clusters or electronic moments fluctuating slow enough to cause a discernible relaxation of the zero-field muSR asymmetry spectrum. Consequently, our measurements on MSF-grown single crystals rule out the generation of spontaneous magnetic fields in the bulk that would occur near impurities or lattice defects if the superconducting state of UTe2 breaks time-reversal symmetry. This result suggests UTe2 is characterized by a single-component superconducting order parameter.

description: Magnetic fields play an important role in star formation by regulating the removal of angular momentum from collapsing molecular cloud cores. Hall diffusion is known to be important to the magnetic field behaviour at many of the intermediate densities and field strengths encountered during the gravitational collapse of molecular cloud cores into protostars, and yet its role in the star formation process is not well-studied. We present a semianalytic self-similar model of the collapse of rotating isothermal molecular cloud cores with both Hall and ambipolar diffusion, and similarity solutions that demonstrate the profound influence of the Hall effect on the dynamics of collapse. The solutions show that the size and sign of the Hall parameter can change the size of the protostellar disc by up to an order of magnitude and the protostellar accretion rate by fifty per cent when the ratio of the Hall to ambipolar diffusivities is varied between -0.5 <= eta_H / eta_A <= 0.2. These changes depend upon the orientation of the magnetic field with respect to the axis of rotation and create a preferred handedness to the solutions that could be observed in protostellar cores using next-generation instruments such as ALMA. Hall diffusion also determines the strength and position of the shocks that bound the pseudo and rotationally-supported discs, and can introduce subshocks that further slow accretion onto the protostar. In cores that are not initially rotating Hall diffusion can even induce rotation, which could give rise to disc formation and resolve the magnetic braking catastrophe. The Hall effect clearly influences the dynamics of gravitational collapse and its role in controlling the magnetic braking and radial diffusion of the field merits further exploration in numerical simulations of star formation.

After establishing that the Arkadian settlements in question were indeed poleis, and reviewing all previous scholarship on the sites, the fortification circuit of each polis is explored through the local history, the geographical/topographical setting, the architectural components of the fortifications themselves, and finally, the overall defensive planning inherent in their construction. Based an understanding of all of these factors, including historical probability, a chronology of construction for each site is provided. The synthesis made possible by the data gathered from the published literature and collected during the field reconnaissance of every site, has confirmed a number of interesting and noteworthy regionally specific patterns. Related to chronology, it is significant that there is no evidence for fortified poleis in Arkadia during the Archaic period, and when the poleis were eventually fortified in the Classical period, the fact that most appeared in the early fourth century BCE, strategically distributed in limited geographic areas, suggests that the larger defensive concerns of the Arkadian League were a factor. Regarding the construction and architecture of the city walls, not only where the fortifications of every polis comprised of a mudbrick superstructure, but in all periods, polygonal masonry and trapezoidal masonry were equally viable options for the stone foundations. In this regard, it is established that when used alone, the type of masonry is not a reliable stylistic indicator for establishing the relative date of a circuit. Moreover, it is interesting to note that the location of every single site chosen was provided with protection in the form of some sort of watercourse. Finally, concerning innovations in siege warfare and offensive artillery, the defensive responses of the Arkadian fortifications follow the same general developments observable in the circuits found throughout the Greek world.

description: The ZFC and FC magnetization dependence on temperature was measured for BiFeO3 ceramics at the applied magnetic field up to H=10T in 2K-1000K range. The antiferromagnetic order was detected from the hysteresis loops below the Neel temperature TN=646K. In the low magnetic field range there is an anomaly in M(H), probably due to the field-induced transition from circular cycloid to the anharmonic cycloid. At high field limit we observe the field-induced transition to the homogeneous spin order. From the M(H) dependence we deduce that above the field Ha the spin cycloid becomes anharmonic which causes nonlinear magnetization, and above the field Hc the cycloid vanishes and the system again exhibits linear magnetization M(H). The anomalies in the electric properties, which are manifested within the 640K-680K range, coincide to the anomaly in the magnetization M(T) dependence, which occurs in the vicinity of TN. We propose to ascribe this coincidence to the critical behaviour of the chemical potential, related to the magnetic phase transition.

description: We demonstrate the control of entanglement in a hybrid optomechanical system comprising an optical cavity with a mechanical end-mirror and an intracavity Bose-Einstein condensate (BEC). Pulsed laser light (tuned within realistic experimental conditions) is shown to induce an almost sixfold increase of the atom-mirror entanglement and to be responsible for interesting dynamics between such mesoscopic systems. In order to assess the advantages offered by the proposed control technique, we compare the time-dependent dynamics of the system under constant pumping with the evolution due to the modulated laser light.

description: We will investigate if the non-technical skill performance of medical emergency personnel differ between two different real-life scenarios, using an event-based observational sheet. The participants are randomized to one of two simulated real-life emergency scenarios. We will do a manipulation check to see if the simulated real-life emergency scenarios do differ in their stressfulness in the first place. Additionally, we want to investigate whether the psychological (e.g., state anxiety, perceived stress) or physiological data (IV) (e.g., cortisol, alpha-amylase) explain variations of the non-technical skills (DV) (in total and/or sub-category scores).

Psy-Knowledge and the Problem of ‘Pain Without Lesion’

description: This thesis examines the two most significant responses to the problem of pain without lesion by the Western psy-complex in the last 150 years. Through a close reading of disciplinary discourses, it specifically examines the differential techniques and vocabularies deployed by expert practitioners of psychoanalytic psychiatry (1895 – 1961) and cognitive psychology (1963 – 1995) in their efforts to render pain without lesion, a definitionally intangible and subjective phenomenon, into an identifiable, knowable, and workable entity. In doing so, I examine the way that the mind was brought into the question of pain by influential psychiatrists and psychologists: Freud, H.S. Sullivan, and Szasz in psychiatry, and Ellis, Beck, and M.J. Sullivan in cognitive psychology. In psychoanalytic psychiatry, pain without lesion was understood as a symptom of hysteria, which was caused by the unconscious conversion of emotional suffering into physical pain. The goal of psychoanalytic treatment was to increase patients’ self-knowledge and help them experience a broader range of emotions. Addressing chronic pain, cognitive psychology focussed instead on “pain cognitions,” peoples’ mental and emotive reactions to pain. The goal of their treatment was to teach patients how to monitor their thoughts so that they could identify and change cognitions that made pain worse. In this thesis, I consider the implication of these discourses in shaping the range of possible experience for those in pain, the assumptions they reveal about human nature and responsibility, and the degree to which they do and do not consider those in pain as socially positioned. I argue that the cognitive approach to pain without lesion is less equipped to consider aspects of the patient’s lifeworld that were once important in psychoanalytic considerations of pain, and that revisiting psychoanalytic ideas regarding the relationships between mind, pain, and the lifeworld may benefit contemporary pain researchers.
Peer PPP-RTK: toward an affordable real-time high accuracy service

description: The objective of this thesis is to develop, test and analyze the performance of a high accuracy GNSS PPP-RTK (Precise Point Positioning- Real Time Kinematic) operational framework based on a dense network of peer users, through the exchange of precise Ionospheric and Tropospheric estimates between peers. The PPP-AR (PPP Ambiguity Resolution) technique, based on the use of precise satellite orbit and clocks, needs satellite biases estimates provided to receivers by external sources. It also usually requires a long convergence time for fixing carrier phase ambiguities to their correct integer values. The novel approach developed herein reduces convergence time in a network of closely spaced (on the order of a few km or less) user receivers performing PPP-RTK with the addition of sharing precise STEC (Slant Total Electron Content) and ZTD (Zenith Tropospheric Delay) estimates. These are applied by the users as constraints for faster convergence to sub-decimetre accuracies. This approach is named Peer PPP-RTK. Peer solutions are processed through a decentralized Federated Kalman Filter approach, where all peers are considered as independent local filters, deriving autonomously their own federated solutions and integrating closer peer ionospheric and tropospheric estimations. The resulting processing engine is tested first through simulations and then in a real GNSS network of permanent reference stations densified through VRS (Virtual Reference Station) representing kinematic users. A performance analysis to assess the impact of network receiver spacing with different scales of ad-hoc networks is carried out in order to simulate possible application scenarios (e.g. cadastral surveying, car information sharing and crowdsourcing in a Collaborative – Intelligent Transportation System perspective). To evaluate the performance of a dense network of peers in a city, a Monte Carlo simulation over 500 randomly distributed networks and different application scenarios is carried out and convergence time statistics are derived through Minimum Spanning Tree analysis. Analysis of these tests shows a percentage convergence time improvement of the Peer PPP-RTK approach with respect to the PPP-AR case for a network of 50 close peers in an area of 100 km2 of 37% (in harsh scenarios with high shadowing and relevant convergence time increase) to 43% (in nominal scenario with nominal PPP-AR convergence times), while preserving an accuracy of at least 5 cm after convergence. This is a highly significant improvement as it has the potential to result in minor operating costs for scores of applications. The PPP-RTK collaborative approach paves the way for the development of a Global PPP-RTK development for a host of large scale applications while reducing the number of Reference Stations required and associated infrastructure costs.

description: English Language Learners (ELLs) are an increasing presence in Canadian schools. However, little research has been done to examine certain skills of ELL students, such as written expression. The purpose of this study was to explore contributing factors to ELL students’ writing quality. The present study gathered written samples from ELL students from Western Canadian elementary charter schools. Students’ expressive vocabulary was also assessed using a norm-referenced measure. Writing samples were Factors such as vocabulary, printing quality, and spelling skills will were considered in this study. It was determined that vocabulary was a significant contributor to overall writing quality of ELL students. More specifically, lexical reach and vocabulary diversity were the greatest contributors. These findings have important implications for educators and school districts to consider when teaching written expression to ELL students, ensuring they receive equitable education.
