Valvular interstitial cell transformation : implications for aortic valve calcification
Creators: name: Boroomand, Seti
Publisher: name: University of British Columbia
Year: 2014

description: Aortic valve stenosis (AVS) involves the transformation of valvular interstitial cells (VIC) into an osteoblastic phenotype. Such valvular disease is mostly associated with both thickening and calcification of the valve cusps, which is accompanied by inflammation and remodeling of the tissue. This process is mediated by the VIC that carry out an impressive array of functions throughout the calcification process. For this dissertation, I hypothesized that in AVS, VIC transform from a myofibroblast phenotype to osteoblast-like cells and that the canonical Wnt and TGFβ pathways and vitamin D3 interactively and collaboratively contribute to these phenomena. In order to test this hypothesis, I established an in vitro model of calcification by culturing human primary VIC in a pro-calcification conditioned medium. Calcified cells display several molecular characteristic features of human AVS, including increased levels of alkaline phosphatase and the formation of calcium nodules. These changes increased over time and peaked at 28 days of treatment. To define possible mechanisms of AVS, I first characterized human VIC in regards to the process of calcification. I showed for the first time in vitro that these VIC express bone specific markers, the characteristic of normal osteoblasts. To determine the factors involved in osteoblastic transformation in this model, I examined WNT3A and TGFβ, known to be involved in normal bone formation. Both calcified human aortic valve tissues and VIC express excess WNT3A and TGFβ1. Adding WNT3A and TGFβ1 to the VIC cultures increased the levels of cell mineralization. Further, the addition of DKK1, the WNT3A antagonist, decreased VIC calcification in vitro. By using various combinations of WNT3A, TGFB1 and DKK1, I made the novel observation that the suppression of DKK1 by TGFB1 allowed WNT3A to drive calcification in VIC in vitro. Finally, I examined the role vitamin D3 that is associated with vascular calcification in rats. Vitamin D3 can up-regulate VIC calcification in vitro, however its mechanism of action appears to be independent of the Wnt and TGFβ pathways. In conclusion, the canonical Wnt and TGFβ pathways function interactively through DKK1 to transform VIC to osteoblast-like cells and vitamin D3 promotes this process in an independent manner.

description: Universalgreifer sind flexibel einsetzbar und können sich an verschiedene Situationen und Objekte anpassen. Aktuelle formvariable Universalgreifer bestehen überwiegend aus monolithischen polymeren Werkstoffen, deren maximale Einsatztemperaturen bei 300 °C liegen. Somit kann von der Formflexibilität nicht in Bereich profitiert werden in denen höhere Temperaturen vorherrschen und die zu handhabenden Objekte Umformungsprozesse durchschreiten. Solch ein Bereich ist der Schmiedesektor, bei dem die Objekte Temperaturen von bis zu 1250 °C erreichen. Die vorliegende Diskrepanz zwischen der Formvariabilität der Greifer und den Prozesstemperaturen im Schmiedesektor versuchen wir zu schließen. In dieser Arbeit stellen wir das von uns entwickelte Konzept eines formvariablen hochtemperaturbeständigem Handhabungssystem und deren praktische Umsetzung vor, sowie die noch zu lösenden Herausforderungen.
description: Universal grippers are flexible and can adapt to different situations and objects. The shape variability has limitations, for example, the temperature. For manufacturing such shape variable grippers, elastic polymer materials are used. The material has an upper limit of the operating temperature of 300 °C. In the forging sector, the manufactured object change their geometry during the process and reaches temperature up 1250 °C. Here, we see the potential of the utilization of shape variable grippers. Therefore, we developed a system that overcomes the gap between the temperature limitation of current shape variable grippers and the high temperature in forging environments. This paper presents our gripper and the task to be solved in future works.

description: The question of stability against diffusional mixing at the prototypical LaAlO3/SrTiO3(001) interface is explored using a multi-faceted experimental and theoretical approach. We combine analytical methods with a range of sensitivities to elemental concentrations and spatial separations to investigate interfaces grown using on-axis pulsed laser deposition. We also employ computational modeling based on the density function theory as well as classical force fields to explore the energetic stability of a wide variety of intermixed atomic configurations relative to the idealized, atomically abrupt model. Statistical analysis of the calculated energies for the various configurations is used to elucidate the relative thermodynamic stability of intermixed and abrupt configurations. We find that on both experimental and theoretical fronts, the tendency toward intermixing is very strong. We have also measured and calculated key electronic properties such as the presence of electric fields and the value of the valence band discontinuity at the interface. We find no measurable electric field in either the LaAlO3 or SrTiO3, and that the valence band offset is near zero, partitioning the band discontinuity almost entirely to the conduction band edge. Moreover, we find that it is not possible to account for these electronic properties theoretically without including extensive intermixing in our physical model of the interface. The atomic configurations which give the greatest electrostatic stability are those that eliminate the interface dipole by intermixing, calling into question the conventional explanation for conductivity at this interface - electronic reconstruction. Rather, evidence is presented for La indiffusion and doping of the SrTiO3 below the interface as being the cause of the observed conductivity.

description: In the insurance industry, spreadsheets have emerged as an invaluable tool to for product pricing, because it is relatively straightforward to create and maintain complex pricing models using Excel. In fact, Excel is often preferred to "hard-code" whenever there are frequent changes to the calculations and business logic which under-pin the pricing of an insurance product. However, problems arise as soon as spreadsheets are deployed to end-users: version control, security of intellectual property, and ensuring correct usage are obvious issues; frequently, integration with other systems is also a requirement. Zurich Financial Services Group is a leading financial services provider; several possible solutions to these problems have been evaluated, and EASA has been selected as the preferred technology. Other spreadsheet collaboration approaches which were considered include Excel Services, and/or custom-built software; however, EASA has provided clear benefits over these strategies.

description: Environmental scientists often face the challenge of predicting a complex phenomenon from a heterogeneous collection of datasets that exhibit systematic differences. Accounting for these differences usually requires including additional parameters in the predictive models, which increases the probability of overfitting, particularly on small datasets. We investigate how Bayesian hierarchical models can help mitigate this problem by allowing the practitioner to incorporate information about the structure of the dataset explicitly. To this end, we look at a typical application in remote sensing: the estimation of leaf area index of white winter wheat, an important indicator for agronomical modeling, using measurements of reflectance spectra collected at different locations and growth stages. Since the insights gained from such a model could be used to inform policy or business decisions, the interpretability of the model is a primary concern. We, therefore, focus on models that capture the association between leaf area index and the spectral reflectance at various wavelengths by spline-based kernel functions, which can be visually inspected and analyzed. We compare models with three different levels of hierarchy: a non-hierarchical baseline model, a model with hierarchical bias parameter, and a model in which bias and kernel parameters are hierarchically structured. We analyze them using Markov Chain Monte Carlo sampling diagnostics and an intervention-based measure of feature importance. The improved robustness and interpretability of this approach show that Bayesian hierarchical models are a versatile tool for the prediction of leaf area index, particularly in scenarios where the available data sources are heterogeneous.

description: This demo brings together multiple perspectives to decolonising design into the Pluriversal Design Exhibition. The exhibition explores how we might design and engage audiences in virtual environments as alternative spaces to decolonise design practice and shared knowledge production. The collaborative exhibition brings together design research projects from Australia, Denmark, Ecuador, Finland, Ghana, Greenland, Italy, Malaysia and Namibia. For each exhibition space, we ask: How can we create virtual spaces for pluriversal dialogue and engagement? What can a virtual exhibition on decoloniality teach us about designing for the pluriverse? We package our perspectives and artefacts through Mozilla Hubs as a platform to harness our practices. We aim to shift perspectives and push the discussion on decoloniality to the fore within the C&T community, especially concerning different topics of interest at the CT conference, such as; community engagement, knowledge, urban technologies, and designing in pandemic times.

description: We observe apparent hole pockets in the Fermi surfaces of single-layer Bi-based cuprate superconductors from angle-resolved photoemission (ARPES). From detailed low-energy electron diffraction measurements and an analysis of the ARPES polarization-dependence, we show that these pockets are not intrinsic, but arise from multiple overlapping superstructure replicas of the main and shadow bands. We further demonstrate that the hole pockets reported recently from ARPES [Meng et al, Nature 462, 335 (2009)] have a similar structural origin, and are inconsistent with an intrinsic hole pocket associated with the electronic structure of a doped CuO$_2$ plane. The nature of the Fermi surface topology in the enigmatic pseudogap phase therefore remains an open question.

description: Nonlinear periodic systems, such as photonic crystals and Bose-Einstein condensates (BECs) loaded into optical lattices, are often described by the nonlinear Schrödinger/Gross-Pitaevskii equation with a sinusoidal potential. Here, we consider a model based on such a periodic potential, with the nonlinearity (attractive or repulsive) concentrated either at a single point or at a symmetric set of two points, which are represented, respectively, by a single δ-function or a combination of two δ-functions. This model gives rise to ordinary solitons or gap solitons (GSs), which reside, respectively, in the semi-infinite or finite gaps of the system's linear spectrum, being pinned to the δ-functions. Physical realizations of these systems are possible in optics and BEC, using diverse variants of the nonlinearity management. First, we demonstrate that the single δ-function multiplying the nonlinear term supports families of stable regular solitons in the self-attractive case, while a family of solitons supported by the attractive δ-function in the absence of the periodic potential is completely unstable. We also show that the δ-function can support stable GSs in the first finite gap in both the self-attractive and repulsive models. The stability analysis for the GSs in the second finite gap is reported too, for both signs of the nonlinearity. Alongside the numerical analysis, analytical approximations are developed for the solitons in the semi-infinite and first two finite gaps, with the single δ-function positioned at a minimum or maximum of the periodic potential. In the model with the symmetric set of two δ-functions, we study the effect of the spontaneous symmetry breaking of the pinned solitons. Two configurations are considered, with the δ-functions set symmetrically with respect to the minimum or maximum of the potential.
A relational geography of heritage in post-1997 Hong Kong
Creators: name: Barber, Lachlan
Publisher: name: University of British Columbia
Year: 2014

description: The central question of this dissertation is: what can Hong Kong teach us about the geography of heritage? The study considers the discursive transformation of cultural heritage as a feature of Hong Kong’s transition since the 1997 retrocession to Chinese sovereignty. Specifically, it traces the contradictory growth of interest in heritage as an urban amenity on the part of the government, and its simultaneous framing as a socio-political critique of neoliberal governance on the part of actors in civil society. The study analyses these dynamics from a perspective attentive to the relationships – forged through various forms of mobility and comparison – between Hong Kong and other places including mainland China, Great Britain, and urban competitors. The project relies on data gathered through English-language research conducted over a period of two and a half years. Sixty in-depth interviews were carried out with experts, activists, professionals and politicians in Hong Kong. Extensive surveys of government documents, the print and online media, and archival materials were undertaken. Other methods employed include site visits and participant observation. The methodology was oriented around the analysis of processes of heritage policy and contestation over a number of sites in Central, Hong Kong and surrounding districts where contradictory visions of the meaning of heritage have played out materially. The dissertation connects with debates in critical heritage studies, urban geography, and Hong Kong studies. A distinctly geographical contribution to heritage studies is made with the application of relational theory, drawn from the emerging literature on urban policy mobilities and urban studies more generally, to the study of the politics of heritage. The consideration of heritage policy, an important feature of the cultural economy and collectively produced and contested, adds to understandings of globalizing urban cultural policy. Finally, the study of these processes – at this particular moment in Hong Kong – provides a new frame for understanding post-handover politics in an era of increasing agitation about the future of the SAR’s relationship with the Mainland and ongoing struggles for democratization.

description: The fractal structure and scaling properties of a 2d slice of the 3d Ising model is studied using Monte Carlo techniques. The percolation transition of geometric spin (GS) clusters is found to occur at the Curie point, reflecting the critical behavior of the 3d model. The fractal dimension and the winding angle statistics of the perimeter and external perimeter of the geometric spin clusters at the critical point suggest that, if conformally invariant in the scaling limit, they can be described by the theory of Schramm-Loewner evolution (SLE_κ) with diffusivity of κ=5 and 16/5, respectively, putting them in the same universality class as the interfaces in 2d tricritical Ising model. It is also found that the Fortuin-Kasteleyn (FK) clusters associated with the cross sections undergo a nontrivial percolation transition, in the same universality class as the ordinary 2d critical percolation.

description: Fast coronal mass ejections (CMEs) generate standing or bow shocks as they propagate through the corona and solar wind. Although CME shocks have previously been detected indirectly via their emission at radio frequencies, direct imaging has remained elusive due to their low contrast at optical wavelengths. Here we report the first images of a CME-driven shock as it propagates through interplanetary space from 8R_Sun to 120R_Sun (0.5AU), using observations from the STEREO Heliospheric Imager (HI). The CME was measured to have a velocity of ~1000 km/s and a Mach number of 4.1\pm1.2, while the shock front stand-off distance (Delta) was found to increase linearly to ~20 R_Sun at 0.5 AU. The normalised standoff distance (Delta/DO) showed reasonable agreement with semi-empirical relations, where D_O is the CME radius. However, when normalised using the radius of curvature, Delta/R_O did not agree well with theory, implying that R_O was under-estimated by a factor of ~3-8. This is most likely due to the difficulty in estimating the larger radius of curvature along the CME axis from the observations, which provide only a cross-sectional view of the CME.

description: The problem of rate control in multi-user multiple-input multiple-output (MIMO) interference systems is formulated as a multicriteria optimization (MCO) problem. The Pareto rate region of the MCO problem is characterized. It is shown that for the convexity of the Pareto rate region it is sufficient that the interference-plus-noise covariance matrices (INCMs) of multiple users with conflicting objectives approach identity matrix. The latter can be achieved by using either orthogonal signaling, time-sharing, or interference cancellation strategies. In the case of high interference, the interference cancellation is preferable in order to increase the Pareto boundary and guarantee the convexity of the Pareto rate region. The Nash bargaining (NB) is applied to transform the MCO problem into a single-objective one. The characteristics of the NB over MIMO interference systems such as the uniqueness, existence of the NB solution, and feasibility of the NB set are investigated. When the NB solution exists, the sufficient condition for the corresponding single-objective problem to have a unique solution is that the INCMs of users approach identity matrix. A simple multi-stage interference cancellation scheme, which leads to a larger convex Pareto rate region and, correspondingly, a unique NB solution with larger user rates compared to the orthogonal and time-sharing signaling schemes, is proposed. The convexity of the rate region, effectiveness of the proposed interference cancellation technique, and existence of the NB solution for MIMO interference systems are examined by means of numerical studies. The fairness of the NB solution is also demonstrated. Finally, the special cases of multi-input single-output (MISO) and single-input single-output (SISO) interference systems are also considered.

description: Many key invariants in the representation theory of classical groups (symmetric groups $S_n$, matrix groups $GL_n$, $O_n$, $Sp_{2n}$) are polynomials in $n$ (e.g., dimensions of irreducible representations). This allowed Deligne to extend the representation theory of these groups to complex values of the rank $n$. Namely, Deligne defined generically semisimple families of tensor categories parametrized by $n\in \mathbb{C}$, which at positive integer $n$ specialize to the classical representation categories. Using Deligne's work, Etingof proposed a similar extrapolation for many non-semisimple representation categories built on representation categories of classical groups, e.g., degenerate affine Hecke algebras (dAHA). It is expected that for generic $n\in \mathbb{C}$ such extrapolations behave as they do for large integer $n$ ("stabilization"). The goal of our work is to provide a technique to prove such statements. Namely, we develop an algebro-geometric framework to study categories indexed by a parameter $n$, in which the set of values of $n$ for which the category has a given property is constructible. This implies that if a property holds for integer $n$, it then holds for generic complex $n$. We use this to give a new proof that Deligne's categories are generically semisimple. We also apply this method to Etingof's extrapolations of dAHA, and prove that when $n$ is transcendental, "finite-dimensional" simple objects are quotients of certain standard induced objects, extrapolating Zelevinsky's classification of simple dAHA-modules for $n\in \mathbb{N}$. Finally, we obtain similar results for the extrapolations of categories associated to wreath products of the symmetric group with associative algebras.

description: Ground state properties of the repulsive Hubbard model on a cubic lattice are investigated by means of the auxiliary-field quantum Monte Carlo method. We focus on low-density systems with varying on-site interaction $U/t$, as a model relevant to recent experiments on itinerant ferromagnetism in a dilute Fermi gas with contact interaction. Twist-average boundary conditions are used to eliminate open-shell effects and large lattice sizes are studied to reduce finite-size effects. The sign problem is controlled by a generalized constrained path approximation. We find no ferromagnetic phase transition in this model. The ground-state correlations are consistent with those of a paramagnetic Fermi liquid.

Effects of full-body mirror exposure on eating pathology, body image and emotional states: Comparison between positive and negative verbalization

description: Mirror exposure (ME) is an effective technique to improve body image. However, evidence on the underlying mechanisms and the optimal verbalization instruction during ME is lacking. Therefore, this experimental study analyzed mechanisms of ME and therapeutic outcomes by comparing positive (PV) and negative (NV) full-body verbalization. N = 73 healthy females were randomized to a PV or an NV condition. PV participants verbalized positively while NV participants verbalized negatively about their whole body. Each participant underwent three standardized ME sessions. Before and after each ME session, positive affect, negative affect and body satisfaction were assessed. Before the first and after the third ME, participants completed questionnaires on cognitive-affective and behavioral aspects of body image, eating pathology and self-esteem. Regarding within-ME changes, the results indicate that positive affect and body satisfaction decreased while negative affect increased in the NV group but not in the PV group. In contrast, regarding between-ME changes, decreased negative affect as well as positive affect and increased body satisfaction were observed in both groups. However, eating pathology remained stable, whereas body-checking behavior increased and the PV condition was followed by higher levels of self-esteem compared to the NV condition. These findings suggest that both PV and NV improve negative affect and body satisfaction between-ME, and thus seem to be effective ME instructions. Given that NV led to increased negative affect within-ME and did not influence self-esteem, PV might represent the favorable instruction during ME for body-satisfied women.

description: We report on the simultaneous observation, by delayed Bragg diffraction, of four- and six-wave mixing processes in a coherently prepared atomic ensemble consisting of cold cesium atoms. For each diffracted order, we observe different temporal pulse shapes and dependencies with the intensities of the exciting fields, evidencing the different mechanisms involved in each process. The various observations are well described by a simplified analytical theory, which considers the atomic system as an ensemble of three-level atoms in Λ configuration.

description: Refactoring is a change made to the internal structure of software to make it easier to understand and cheaper to modify without changing its observable behaviour. A database refactoring is a small change to the database schema which improves its design without changing its semantics. This paper presents example 'spreadsheet refactorings', derived from the above and taking into account the unique characteristics of spreadsheet formulas and VBA code. The techniques are constrained by the tightly coupled data and code in spreadsheets.

description: We discuss an experiment underway at Imperial College London to measure the permanent electric dipole moment (EDM) of the electron using a molecular beam of YbF. We describe the measurement method, which uses a combination of laser and radiofrequency resonance techniques to detect the spin precession of the YbF molecule in a strong electric field. We pay particular attention to the analysis scheme and explore some of the possible systematic effects which might mimic the EDM signal. Finally, we describe technical improvements which should increase the sensitivity by more than an order of magnitude over the current experimental limit.

description: In this study, the protection motivation theory (PMT) was used to investigate factors influencing self-reported willingness to donate and actual donations to conserve endangered bird species. The PMT was extended to include sociodemographic factors (gender, age, education, and income), as well as knowledge about and attitudes toward birds. Data were collected in Germany through an online questionnaire (N = 579, MAge = 49.15, SD = 16.93, women = 51.6 %). Regression analyses showed that the cognitive assessment processes of the PMT, (1) threat appraisal of endangered bird species, and (2) coping appraisal of threat toward endangered bird species were significant predictors of an individual’s willingness to donate. An individual’s attitudes toward birds strengthened willingness to donate, but not actual donations. Knowledge about birds had no influence on willingness to donate or actual donation behavior. Women were more likely to donate and higher perceived barriers were associated with lower rates of actual donations. A discrepancy between willingness to donate and actual donations is evident, which indicates an intention-behavior gap. The results suggest that conservation and education campaigns should be used to increase the population's awareness of existing threats toward endangered bird species, including the constructs of PMT, which could positively influence both willingness to donate and actual donations. Similarly, engagement initiatives could target individuals' self-efficacy to engage in bird conservation and possible coping measures should be made transparent and tangible by stakeholders looking to foster bird conservation.

description: We use tropical geometry to compute the multidegree and Newton polytope of the hypersurface of a statistical model with two hidden and four observed binary random variables, solving an open question stated by Drton, Sturmfels and Sullivant in "Lectures on Algebraic Statistics" (Problem 7.7). The model is obtained from the undirected graphical model of the complete bipartite graph $K_{2,4}$ by marginalizing two of the six binary random variables. We present algorithms for computing the Newton polytope of its defining equation by parallel walks along the polytope and its normal fan. In this way we compute vertices of the polytope. Finally, we also compute and certify its facets by studying tangent cones of the polytope at the symmetry classes vertices. The Newton polytope has 17214912 vertices in 44938 symmetry classes and 70646 facets in 246 symmetry classes.
