description: Smad8 is a transcriptional regulator involved in many cellular processes, such as cell differentiation. During tissue regeneration, cell differentiation takes place. Particularly, it has been reported before that the combined effect of a truncated form of Smad8 (hcSmad8) and BMP2 induces the differentiation of mesenchymal stem cells (MSCs) into tenocytes (Hoffmann et al.,2006). Smad8 is therefore considered a promising molecule that can be used to enhance tendon regeneration. This can be achieved, for example, by loading implants with hcSmad8. Hence, there is an interest in producing cSmad8 in a recombinant way. Herein, it is reported the production, purification, and characterization of human cSmad8 produced in E. coli. To allow the internalization of cSmad8, the Transactivator Sequence (TAT) of the HIV was genetically attached. TAT-hcSmad was refolded from inclusion bodies, purified by heparin chromatography, characterized by physicochemical methods, and finally, the internalization and biological activity were tested in MSCs. The purified TAT-hcSmad8 displayed a hydrophobic core consisting of a mixture of α-helixes and β-sheets. TAT-hcSmad8 was also able to efficiently internalize into C3H10T1/2 cells. Luciferase-based reporter assays suggested that TAT-hcSmad8 is active as it interferes with the BMP signaling pathway. More research needs to be done around Smad8 to understand better its role in cells and with this fully exploit Smad8 potential.

description: We studied the abundance of HCN, H13CN, and HN13C in a sample of prestellar cores, in order to search for species associated with high density gas. We used the IRAM 30m radiotelescope to observe along the major and the minor axes of L1498, L1521E, and TMC 2, three cores chosen on the basis of their CO depletion properties. We mapped the J=1-0 transition of HCN, H13CN, and HN13C towards the source sample plus the J=1-0 transition of N2H+ and the J=2-1 transition of C18O in TMC 2. We used two different radiative transfer codes, making use of recent collisional rate calculations, in order to determine more accurately the excitation temperature, leading to a more exact evaluation of the column densities and abundances. We find that the optical depths of both H13CN(1-0) and HN13C(1-0) are non-negligible, allowing us to estimate excitation temperatures for these transitions in many positions in the three sources. The observed excitation temperatures are consistent with recent computations of the collisional rates for these species and they correlate with hydrogen column density inferred from dust emission. We conclude that HCN and HNC are relatively abundant in the high density zone, n(H2) about 10^5 cm-3, where CO is depleted. The relative abundance [HNC]/[HCN] differs from unity by at most 30 per cent consistent with chemical expectations. The three hyperfine satellites of HCN(1-0) are optically thick in the regions mapped, but the profiles become increasingly skewed to the blue (L1498 and TMC 2) or red (L1521E) with increasing optical depth suggesting absorption by foreground layers.

Distribution. Finland.—Westpalearctic: northern and central Europe (Linsenmaier 1959).
Remarks. The species is only known from a few localities in western Finland, where it occurs in warm sandy habitats, often close to the coast. It has been classified as vulnerable in Finland (Paukkunen 2010). Trautmann (1927, 1930) reported the species from southern Sweden, and later also Balthasar (1954), Noskiewicz & Pulawski (1958), Móczár (1967) and Banaszak (1980) mentioned the species from the country. We have considered these records as doubtful, as we have not seen any Swedish specimens in collections. The closest known records outside Finland are from Poland (Banaszak 1980), Belarus (Shljachtenok 2006) and northern Germany (Jakobs & Kornmilch 2007).

The Structure and Function of Task Conflict: An Investigation of Quality and Frequency
Creators: name: Derban, Genevieve
Publisher: name: Graduate Studies
Year: 2017
Subjects: subject: Psychology--Industrial
subject: team
subject: team conflict
subject: quality

description: The impact of task-focused discussions in teams should theoretically support innovative performance; yet, research has revealed mixed findings. The current research proposed that in addition to measuring Task Conflict (TC) frequency, researchers should concurrently measure the quality of TC, which would represent distinct constructs. Further, this research proposes that these emergent states are further distinguished by different trends over time and unique drivers. Results support quality and frequency being two distinct states; however, they both follow a similar positive trajectory over time. Although only marginally significant, quality appeared to be the stronger predictor of team performance. Additionally, initial psychological safety appears to drive both frequency and quality but relationship conflict only drives TC quality. The current findings demonstrate that considering the “quality” of task-focused discussion, and how it unfolds over time, is uniquely related to team performance and the importance of considering this new construct in future theoretical conflict frameworks.
Identification and mechanism of action of keratinocyte-releasable factors in regulation of extracellular matrix expression
Creators: name: Ghaffari, Abdi
Publisher: name: University of British Columbia
Year: 2010

description: The complexity of multi-cellular organisms demands a dynamic reciprocity between neighboring cells in any given tissue. The disruption in keratinocytes and fibroblasts cross-talk in skin has been linked to an imbalance in extracellular matrix (ECM) expression leading to the onset of fibrosis such as hypertrophic scarring. Our group has recently identified 14-3-3σ or stratifin (SFN) as a potent MMP-1 stimulatory factor in fibroblasts. In this doctoral research project, we hypothesized that SFN can modulate other ECM components and execute its transmembrane signaling through interaction with a receptor on the surface of fibroblasts. Three specific objectives were accomplished in this project. Under objective 1, ECM gene expression profile of fibroblasts treated with SFN or co-cultured with keratinocytes was characterized by an ECM-pathway specific gene array and revealed that SFN upregulates a wider range of MMPs such as MMP-3, 8, 10, and 24 other than MMP-1. As SFN was not responsible for the keratinocyte-mediated decrease in collagen expression, under objective 2 attempts were made to characterize the nature of a collagen inhibitory factor in keratinocyte-conditioned medium (KCM). Analysis of keratinocyte/fibroblast co-culture and KCM revealed a 30-50 kDa keratinocyte-derived collagen inhibitory factor with stable activity at high temperature (56 ºC) and acidic environment (pH=2, 30 min). Under objective 3, SFN’s transmembrane signaling mechanism was investigated by utilizing a combination of receptor ectodomain biotin labeling, serial affinity purification, and MS/MS to identify aminopeptidase N or CD13 (APN) as a potential SFN receptor in fibroblasts. APN/SFN binding was further confirmed by immunoprecipitation, cross-linking, and co-distribution studies. Expression of APN and SFN increased after wound closure in a rabbit ear fibrotic model as well as a longitudinal study in rats. The transient knockdown of APN blocked SFN-mediated p38 MAPK activation and MMP-1 expression. Collectively, the findings presented in this thesis provide further support for the importance of keratinocyte-releasable factors in the regulation of ECM and MMP expression in fibroblasts. We also identify APN as a novel cell surface receptor for SFN. Therefore, our findings may provide additional therapeutic tools for the regulation of MMP expression in dermal fibrosis and chronic wound healing disorders.

description: The O(4) supersymmetry of the hydrogen atom is utilized to construct a complete basis using only the bound state wave functions. For a large class of perturbations, an expansion of the electron (exciton) wave function into such a complete set reduces the perturbed Schroedinger equation to a standard eigenvalue problem with an equidistant unperturbed spectrum. A high-order polarizability of the ground state of the hydrogen atom in a static electric field is calculated via Rayleigh-Schroedinger perturbation theory for illustration of the new method.

Computational Modeling of Electrical Cell-to-cell Interactions in Cardiac Tissue: Applications to Model Parameter Selection and Pacemaker Function

description: Cell-to-cell interactions are important in determining the electrophysiological behavior of cardiac tissue. In this research, computer modeling is used to investigate the importance of these interactions in two different contexts: 1) how to adjust parameters in single cell models to accurately reproduce tissue behavior, and 2) determining requirements for successful conduction at the interface between different tissue types, specifically from the sinoatrial node (SAN) to the atrium. Membrane resistance (Rm), the inverse of the slope of the current-voltage (I/V) relationship for a cardiac myocyte, is an important determinant of electrical cell-to-cell interactions. Experimentally, Rm can be measured by applying a small current and measuring the resulting change in membrane voltage. To investigate the importance of Rm, a multi-objective genetic algorithm approach was developed for enhancing the fitting of action potentials (APs) in single cell models. Rm was fit at several points during the AP along with AP morphology. The results demonstrate that including Rm as a fitting criterion yields improved convergence, reduced variability in parameter estimates, and improved robustness, while specifically improving the ability of the model to reproduce tissue behavior. Bioengineered pacemakers are cellular constructs intended to replace the SAN pacemaker function. The interface between the SAN and atrium appears to have features designed to facilitate conduction. Depending on the species, these features involve gradual transitions (gradients) in ion channel densities and coupling conductance, or insulating boundaries with conduction at discrete exit points only. We used simulations to determine the importance of each of these features, with the aim to provide guidance to future development of bioengineered pacemakers. We found that gradients in ionic conductance (specifically ICaL) are required in rabbit SAN. There is narrow range of coupling for which the SAN is able to propagate towards atrium without coupling gradients. In canine SAN, these gradients support conduction. However, gradients are not required, provided conduction from SAN to atrium is restricted to discrete exit points. This suggests two possible strategies for successful conduction at the interface between a bioengineered pacemaker and the atrium: 1) engineer the construct to have appropriate ionic current and intercellular coupling gradients, or 2) functionally insulate a homogeneous construct from the atrium with conduction only at discrete points.

description: The internal dynamics of strongly interacting systems and that of biomolecules such as proteins display several important analogies, despite the huge difference in their characteristic energy and length scales. For example, in all such systems, collective excitations, cooperative transitions and phase transitions emerge as the result of the interplay of strong correlations with quantum or thermal fluctuations. In view of such an observation, some theoretical methods initially developed in the context of theoretical nuclear physics have been adapted to investigate the dynamics of biomolecules. In this talk, we review some of our recent studies performed along this direction. In particular, we discuss how the path integral formulation of the molecular dynamics allows to overcome some of the long-standing problems and limitations which emerge when simulating the protein folding dynamics at the atomistic level of detail.

description: Alexandre Grothendieck, through his groundbreaking work in the 1960s, helped bring algebraic geometry into the modern era. Among his vast work from this period, there is the notion of a Galois category - an example of one being the category of finite etale covers of a scheme. In this thesis we shall investigate Galois categories from a purely categorical perspective and construct examples. In particular, we investigate what it means to be a covering of an object and when such objects form a Galois category.

description: We theoretically predict and experimentally demonstrate that several different particle species can be separated from each other by means of a ratchet device, consisting of periodically arranged triangular (ratchet) shaped obstacles. We propose an explicit algorithm for suitably tailoring the externally applied, time-dependent voltage protocol so that one or several, arbitrarily selected particle species are forced to migrate oppositely to all the remaining species. As an example we present numerical simulations for a mixture of five species, labelled according to their increasing size, so that species 2 and 4 simultaneously move in one direction and species 1, 3, and 5 in the other. The selection of species to be separated from the others can be changed at any time by simply adapting the voltage protocol. This general theoretical concept to utilize one device for many different sorting tasks is experimentally confirmed for a mixture of three colloidal particle species.

description: The requirement of reliability and safety of hydraulic systems is always relevant: both in the design process, and in the operation, repair and monitoring processes. Currently, systems designed to support decision-making processes, in particular situational-advising systems, as a type of expert systems, are becoming particularly relevant. The main components of the formalization and construction of fuzzy situational models of correspondences of the type “situation — causes — actions” (S-C-A) for the processes of defect detection of a hydraulic unit are described.
Statistical properties of defect turbulence in two and three dimensions

subject: Pattern formation

description: Spatiotemporal chaos in oscillatory and excitable media is often characterized by the presence of phase singularities called defects. Understanding such defect mediated turbulence is an important challenge in nonlinear dynamics. This is especially true in the context of ventricular fibrillation in the heart, where the mechanism leading to ventricular fibrillation, and the importance of the thickness of the ventricular wall, is contentious. Here, we study defect mediated turbulence arising in many regimes of conceptual models of oscillatory and excitable media and investigate the statistical properties of the turbulent state that results. Two central ideas are put under scrutiny. First, that the turbulence is driven, and its observables influenced, by the mechanism of breakup and second, that the dimensionality of the medium leads to a different, potentially more complex, turbulence. We find evidences that support the idea of instability driven turbulence for different 2-dimensional instabilities. Furthermore, breakup from purely 3-dimensional instabilities offers a completely different mechanism. For 2D mechanisms in 3D media, we find that the thickness of the medium does not have a significant influence far from onset in fully developed turbulence while there is a clear transition in behavior if the system is close to a spiral instability. We further provide clear evidence that the observed transition is purely a consequence of the dimensionality of the medium. Using 3D defect tracking, we show that the statistical properties arising from 2D instability driven turbulence are different from those in turbulent regimes arising from 3D instabilities, but only close to onset. As a consequence of this study, we are lead to the counterintuitive conclusion that even in the absence of pure 3D instabilities, 3D simulations may be necessary to capture even the simplest statistical feature of the turbulent behaviour of real 3D systems. However, even if the 3D statistics are different from the 2D ones, they are not distinguishable in a general context, a conclusion that opposes a previous conjecture.

description: In the paper we develop the $p$-adic theory of discrete automata. Every automaton $\mathfrak A$ (transducer) whose input/output alphabets consist of $p$ symbols can be associated to a continuous (in fact, 1-Lipschitz) map from $p$-adic integers to $p$ integers, the automaton function $f_\mathfrak A$. The $p$-adic theory (in particular, the $p$-adic ergodic theory) turned out to be very efficient in a study of properties of automata expressed via properties of automata functions. In the paper we prove a criterion for finiteness of the number of states of automaton in terms of van der Put series of the automaton function. The criterion displays connections between $p$-adic analysis and the theory of automata sequences.

description: This thesis focuses on anticipating electricity prices, reliability of supply, and emissions in deregulated energy-only markets in the medium and long term considering both the large-scale integration of wind generation and other inflexible generation and the strategic behavior of other flexible generators. The first part of this thesis evaluates the effects of large-scale wind powered generation on the fixed cost recovery of existing conventional generators and the ability of existing conventional generators to profit from economically withholding energy. The anticipated impact on reliability of supply and prices in the medium term is also evaluated. In the second part of the thesis, a general model of long term equilibrium that allows for generation additions and retirements is developed and applied to determine the distribution of electricity prices and reliability of supply at equilibrium assuming competitive, inflexible, and strategic generator behaviors. The third part of the thesis applies Probabilistic Neural Networks (PNN) to model complex individual generator behaviors. The PNN are integrated in simulations of existing markets to anticipate prices, the likely entry of new generation, reliability of supply, and emissions in the medium term.

description: This study made use of postcolonial theory and the in depth interview to explore the teaching experience of Global North and Global South female social work instructors. Through active interviews from 2008 – 2010, 13 female academics; eight from the Global North and five from the Global South responded to the research question; What is the experience of teaching social work in the Global South? Participants report on the ways they teach and engage in community and cultural learning within their host/home country, providing information on their teaching practice, and use of educational resources. For many, this was their first opportunity for reflecting and sharing professional teaching experience and insights in a structured manner. This research offers three contributions. First, major findings reinforce that colonization continues to influence the delivery of social work education in the Global South. Second, despite this reality, there is also a movement toward collaboration and engagement among academics from the South and North that facilitates adaption and creation of culturally relevant curricula to suit the local context. Third, as one of few studies exploring the teaching experience of Global South and North academics, this scholarship provides some practical recommendations to dismantle the influence of postcolonialism on social work education. These recommendations include preparation training for internationally mobile social work academics, a community of practice for South and North academics, and a call for academic activism by individuals and institutions from both the Global North and South to foster mutual respect and develop inclusive educational partnerships.

description: Experimental implementations of quantum information processing have now reached a level of sophistication where quantum process tomography is impractical. The number of experimental settings as well as the computational cost of the data post-processing now translates to days of effort to characterize even experiments with as few as 8 qubits. Recently a more practical approach to determine the fidelity of an experimental quantum process has been proposed, where the experimental data is compared directly to an ideal process using Monte Carlo sampling. Here we present an experimental implementation of this scheme in a circuit quantum electrodynamics setup to determine the fidelity of two qubit gates, such as the cphase and the cnot gate, and three qubit gates, such as the Toffoli gate and two sequential cphase gates.

description: This thesis is an expansion of a Capstone Project where a set of portable sprint starting blocks that can be used for training was developed. For this thesis, two piezo-electric sensors were implemented in the blocks that transmitted data from each of the sprinter’s feet to a micro-controller. The sensors, after a series of impact hammer tests, offered a cost-efficient means of collecting valuable telemetric data during a sprint start, and crucially, were non-intrusive. Majority of the athletes demonstrated a consistent three-peak-force pattern in the data collected which was statistically correlated to qualitative performance scores given by a coach evaluating the start. The correlation helped develop a fuzzy method that estimated a performance score for sprint starts and detected false starts. The need to validate this method also helped produce a definitive coach’s sprint start evaluation checklist from the National Coaching Certification Program.

description: By demanding consistency of the Legendre transform construction of hyperkähler metrics in projective superspace, we derive the expression for the Darboux coordinates on the hyperkähler manifold. We apply these results to study the Coulomb branch moduli space of 4D, N=2 super-Yang-Mills theory (SYM) on R^3 x S^1, recovering the results by GMN. We also apply this method to study the electric corrections to the moduli space of 5D, N=1 SYM on R^3 x T^2 and give the Darboux coordinates explicitly.

description: This research focuses on the performance of GNSS receiver carrier phase tracking loops for earthquake monitoring systems. An earthquake was simulated using a hardware simulator; position, velocity and acceleration displacements were obtained to recreate the dynamics of the 2011 Tohoku earthquake, Japan. Using a software defined receiver, various tracking bandwidths and integration times were tested. Using the phase lock indicator and carrier-to-noise ratio as metrics, an adaptive carrier tracking loop was successfully designed and tested to maximize performance for this application. Four different simulations were done to assess the performance of the adaptive carrier tracking loop. Two simulations with carrier-to-noise ratios greater and less than 35 dB-Hz were done using the original dynamics of the 2011 Tohoku earthquake. The other two simulations tested were the dynamics of the same earthquake scaled by a factor of 10, with carrier-to-noise ratios greater and less than 35 dB-Hz.
Stream-catchment connectivity and streamflow dynamics in a montane landscape
Creators: name: Szeftel, Pascal
Publisher: name: University of British Columbia

description: The concept of hydrologic connectivity provides a temporally dynamic aspect to an otherwise static description of streamflow generation processes. The research presented in this dissertation focuses on the linkages between slopes, riparian zones and streams – the three main constitutive landscape elements of steep montane catchments – and the ways in which hydrologic connectivity affects hydrological processes. The research was conducted in Cotton Creek Experimental Watershed (CCEW), a snow-dominated meso-scale catchment located in the Kootenay Mountains, south-eastern British Columbia, Canada. First, the controls on slope water delivery to the stream were examined across a range of flow regimes. The spatial patterns and their dominant controls shifted from high to low flow. Catchment contributing area and slope length were good predictors of streamflow generation during high flow periods. At low flow, a new topographic index reflecting the spatial organization of flow pathways within a catchment was the dominant control on streamflow generation. Second, the dynamics of coupling between slopes, riparian zone and stream were examined through analysis of streamflow diel fluctuations. Periods representing high, intermediate and low baseflow were selected to investigate the dominant controls on diel fluctuations at nine stream gauges arranged in a nested design. Streamflow diel fluctuations were generated by evapotranspiration, the diurnal pattern of which was represented using vapour pressure deficit measured at a weather station within the catchment. Response times between climatic forcing and the various stream gauges revealed that both in-stream wave advection and dispersion processes, and transient storage processes in the riparian aquifers needed to be accounted for to explain spatio-temporal patterns of streamflow diel fluctuations. Last, the influence of slope water contributions to the stream on modelled solute transient storage and in-stream transport was examined. It was found that calibrated parameters representing transient storage vary systematically with the assumed magnitude and location of water fluxes to and from the stream.

description: An application of the equation proposed by the present authors, which is equivalent to the static field equation of the Faddeev model, is discussed. Under some assumptions on the space and on the form of the solution, the field equation is reduced to a non-linear ODE of second order. By solving this equation numerically, some solitonic solutions are obtained. It is discussed that the product of two integers specifying solutions may be identified with the Hopf topological invariant.
Le christianisme chez Corneille : Lumière sur la subversion morale

description: Avec l’écriture de ses tragédies chrétiennes Polyeucte (1643) et Théodore (1646), pièces qui relèvent de la question très sensible qui est celle de la religion chrétienne au théâtre, Pierre Corneille agite autant les gens de lettres que les hommes d’Église. En ajoutant le drame du martyre à sa plume, il rassemble deux concepts ; le théâtre et la religion, tous deux en conflit depuis des siècles déjà, ce qui pervertit rapidement la tragédie. À travers la combinaison de la période romaine avec la croyance catholique, Corneille met le péché mortel au premier plan et subvertit alors l’instruction morale au XVIIe siècle, bousculant la bienséance. Il ose donc s’opposer aux règles du théâtre, à la morale sociale et religieuse, ainsi qu’à l’autorité royale en traitant de sujets tels que la sexualité, les mœurs et le péché. C’est ainsi que ces deux tragédies chrétiennes constituent une étape importante de la carrière esthétique, dramaturgique et idéologique de Corneille.
