description: We investigate experimentally a two-dimensional rocking ratchet for cold atoms, realized by using a driven three-beam dissipative optical lattice. AC forces are applied in perpendicular directions by phase-modulating two of the lattice beams. As predicted by the general theory [S. Denisov et al., Phys. Rev. Lett. 100, 224102 (2008)], we observe a rectification phenomenon unique to high-dimensional rocking ratchets, as determined by two single-harmonic drivings applied in orthogonal directions. Also, by applying two bi-harmonic forces in perpendicular directions, we demonstrate the possibility of generating a current in an arbitrary direction within the optical lattice plane.
Nocturnality under the midnight sun: behavioural adaptations of the little brown bat (Myotis lucifugus) at 60°N latitude

description: Northern environments are highly dynamic with pronounced seasons and a large annual range in photoperiod. As latitude increases, summer ambient temperature is cooler and summer days lengthen. The goal of my research was to investigate how a hibernating, nocturnal mammal behaves at northern latitudes with the combination of short summers and short summer nights. I investigated the behaviour of Myotis lucifugus at 60°N in the Northwest Territories, Canada. I assessed the effects of cool ambient temperatures on the timing of hibernation and reproduction, nightly activity, and foraging efficiency compared to southern populations. I found that M. lucifugus exit hibernation at cool ambient temperatures, exhibit delayed parturition, adjust their foraging behaviour to capitalize on reduced night length, and have higher foraging rates (i.e. reduced prey search time) which allow them to gain sufficient pre-hibernation mass. I suggest these adaptations allow populations to persist at northern latitudes.

description: The two-dimensional $\mathcal{N}=(2,2)$ Wess-Zumino (WZ) model with a cubic superpotential is numerically studied with a momentum-cutoff regularization that preserves supersymmetry. A numerical algorithm based on the Nicolai map is employed and the resulting configurations have no autocorrelation. This system is believed to flow to an $\mathcal{N}=(2,2)$ superconformal field theory (SCFT) in the infrared (IR), the $A_2$ model. From a finite-size scaling analysis of the susceptibility of the scalar field in the WZ model, we determine $1-h-\Bar{h}=0.616(25)(13)$ for the conformal dimensions $h$ and $\Bar{h}$, while $1-h-\Bar{h}=0.666...$ for the $A_2$ model. We also measure the central charge in the IR region from a correlation function between conserved supercurrents and obtain $c=1.09(14)(31)$ ($c=1$ for the $A_2$ model). These results are consistent with the conjectured emergence of the $A_2$ model, and at the same time demonstrate that numerical studies can be complementary to analytical investigations for this two-dimensional supersymmetric field theory.

description: We report the results of an improved experiment aimed at determining whether the half-life ($T_{1/2}$) of $^{198}$Au depends on the shape of the source. In this experiment, the half-lives of a gold sphere and a thin gold wire were measured after each had been irradiated in the NIST Center for Neutron Research. In comparison to an earlier version of this experiment, both the specific activities of the samples and their relative surface/volume ratios have been increased, leading to an improved test for the hypothesized self-induced decay (SID) effect. We find T_1/2(sphere)/T_1/2(wire) = 0.9993+/-0.0002, which is compatible with no SID effect.

description: Semi-clathrates are ice like crystalline substance which are like that of gas hydrates. Like clathrate hydrates, the semi-clathrates can entrap gas molecules in its molecular framework. Since semi-clathrate are formed at much milder conditions when compared with the clathrate hydrate. Thus, in the recent years, there has been much interest in using semi-clathrate in applications such as gas storage and separation. The aim of the present study is to measure the dissociation condition of semi-clathrate formed from Tetra-n-butyl ammonium bromide in the presence of the gas mixtures using a developed thermodynamic model. The developed thermodynamic model the PSRK equation of state is used to describe the vapour phase, the LIFAC activity coefficient model is used to compute the activity coefficient in the liquid phase. The van der Waals and Platteeuw theory is employed to describe the semi-clathrate phase. In this model, the Langmuir constants are calculated using the Kihara potential, whereas most of the previously developed model uses the empirical correlation. The thermodynamic model is used in the present work to predict the dissociation condition of the semi-clathrate formed from Tetra-n-butyl ammonium bromide in the presence of the gas mixtures like carbon dioxide (CO2), carbon monoxide (CO), nitrogen (N2) and hydrogen (H2). A good agreement between the experimental and predicted values were observed using this model. The % ARD (average relative deviation) of the calculated and experimental values were in the range of 3.2% to 7.2%.

description: The paper presents a generalized Poisson-Nernst-Planck model of an yttria-stabilized zirconia electrolyte developed from first principles of nonequilibrium thermodynamics which allows for spatial resolution of the space charge layer. It takes into account limitations in oxide ion concentrations due to the limited availability of oxygen vacancies. The electrolyte model is coupled with a reaction kinetic model describing the triple phase boundary with electron conducting lanthanum strontium manganite and gaseous phase oxygen. By comparing the outcome of numerical simulations based on different formulations of the kinetic equations with results of EIS and CV measurements we attempt to discern the existence of separate surface lattice sites for oxygen adatoms and O2- from the assumption of shared ones. Furthermore, we discern mass-action kinetics models from exponential kinetics models.

description: This study is an intervention into a conversation, which began in the late 1990s, about the increasingly fragmented nature of international law. Within that discussion, relatively little is said of the relationship between the international trade and international investment law regimes. It is within this analytical space that my intervention is placed. The adjudicators in both systems play a crucial role in defining the relationship between these branches of international economic law. This thesis focuses on the role that adjudicators play in the continuing conversation about the relationship between the international trade and international investment law regimes. Unlike other studies on the intersection between these two regimes, this thesis examines the extent to which the international trade and international investment law regimes are uniting through the process of adjudication.
Convex Analysis in Quantum Information

description: Convexity arises naturally in the study of quantum information. As a result, many useful tools from convex analysis can be used to give important results regarding aspects of quantum information. This thesis builds up methods using core concepts from convex analysis, including convex optimization problems, convex roof constructions, and conic programming, to study mathematical problems related to quantum entanglement. In this thesis, I develop a method for solving convex optimization problems that arise in quantum information theory by analyzing the corresponding converse problem. That is, given an element in a convex set, I determine a family of convex functions that are minimized at this point. This method is used find explicit formulas for the relative entropy of entanglement, as well as other important quantities used to quantify entanglement, and allows one to show important relationships between them. I also construct a practical algorithm that can be used to compute these quantities. This thesis also presents a method to compute convex roofs of arbitrary entanglement measures evaluated on highly symmetric bipartite states. I also establish a framework for completely characterizing quantum resource theories that are convex. For resource theories with a simple mathematical structure, this gives rise to a complete set of resource monotones that can be computed in practice using semidefinite programs. This has applications to the study of entanglement transformations.

description: Spicules were recently found to exist as two types when a new class of so-called type II spicules was discovered at the solar limb with Hinode. The type II spicules have been linked with on-disk observations of Rapid Blue-shifted Excursions (RBEs) in the Ha and Ca 8542 lines. Here we analyze observations optimized for the detection of RBEs in both Ha and Ca 8542 simultaneously at a high temporal cadence taken with CRISP at the SST. This study used a high-quality time sequence for RBEs at different blue-shifts and employed an automated detection routine to detect a large number of RBEs in order to expand on the statistics of RBEs. We find that the number of detected RBEs is dependent on the Doppler velocity of the images on which the search is performed. Detection of RBEs at lower velocities increases the estimated number of RBEs to the same order of magnitude expected from limb spicules. This shows that RBEs and type II spicules are exponents of the same phenomenon. We provide evidence that Ca 8542 RBEs are connected to Ha RBEs and are located closer to the network regions with the Ha RBEs being the continuation, and show that RBEs have an average lifetime of 83.9 s when observed in both spectral lines with Doppler velocity ranges of 10-25 km/s in Ca 8542 and 30-50 km/s in Ha. In addition, we determine the transverse motion of a much larger sample of RBEs than previous studies and find that like type II spicules, RBEs undergo significant transverse motions, 5-10 km/s. Finally, we find that the intergranular jets discovered in BBSO are a subset of RBEs.

Canadian migrations : reading Canada in nineteenth-century American literature
Creators: name: MacLean, Alyssa Erin
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation contributes to the fields of Canadian literature, American literature, and transnational and hemispheric studies by examining Canada’s place in American Renaissance discussions about imperialism, citizenship, and racial and national identity. In the nineteenth-century US, Canada became symbolically important because of its perceived common origins with the US as well as its increasing resistance to forms of American imperialism. Canadian Migrations examines the significance of the Canada-US relationship by analysing literary representations of two population movements across the Canada-US border: the 1755 deportation of French Catholic Acadians from Canada to the American colonies and the antebellum flight of African Americans north to Canada. American authors gravitated towards these narratives of displacement to and from Canada in order to discuss the meaning of American citizenship and the treatment of racial minorities within US borders. I argue that both of these Canada-US movements prompted critical inquiries in US culture about forms of American imperialism. In Part One, I examine authors such as Nathaniel Hawthorne, Henry Wadsworth Longfellow, and Harriet Beecher Stowe, who portrayed the violent expulsion of Acadians by British troops justified the creation of the United States as a necessary defense against imperial rule. Yet the Acadian expulsion also prompted these authors to question the contemporary US government’s own displacement of racial and linguistic minorities through slavery and westward expansion. In Part Two, I examine the northward movement of fugitive slaves across Lake Erie to Canada. By crossing Lake Erie, Black migrants—and the iconic texts written about them—challenged the conceptual categories that sustained US slavery and imperialism. Authors such as Stowe, Josiah Henson, Lewis Clarke, and William Wells Brown described scenes of nautical transit and transformation across the Lake Erie Passage to contest US slavery and to develop notions of Black citizenship. By recovering this conversation about the significance of Canada-US cross-border movement, I position nineteenth-century Canada within the movement of people and ideas across the Black Atlantic world. Together, my chapters demonstrate how the imagined community of the United States emerged through a series of complex political, cultural, and literary negotiations with Canada.
title: Hydrothermal reconstruction and lithogeochemistry of the Argyle orogenic gold deposit, Baie Verte, Newfoundland
Creators: name: Pawlukiewicz, Maciej

description: The Argyle orogenic gold deposit (543,000 t @2.19 g/t Au indicated, and 517,000 t @1.82 g/t Au inferred resources) is located within Lower Ordovician Snooks Arm Group, Baie Verte Peninsula, Newfoundland. Gold mineralization is hosted as inclusions in secondary pyrite and at pyrite crystal boundaries in a ~50 m thick E-W striking, gently N-dipping tholeiitic gabbro sill. The short distance (200-300 m) from the Scrape thrust, rheological contrast within the heterogenous gabbro and a high content of coarse, reactive ilmenomagnetite were critical to the localization of gold mineralization. Two hydrothermal alteration events affected the gabbro: 1) early, pre-mineralization epidote-albite alteration; and 2) later, mineralization-related sericite-quartz-ankerite-(albite-chlorite-rutile-pyrite-gold) alteration. Within the mineralization-related alteration there are three assemblages: 1) distal chlorite-calcite-rutile ± epidote-albite (30-70 m); 2) intermediate chlorite-epidote-albite-calcite ± ankerite-rutile-hematite-sericite-pyrite (5-30 m); and 3) proximal sericite-quartz-ankerite ± albite-chlorite-rutile-sooty pyrite-gold (2-25 m). Lithogeochemistry, mineral chemistry and short-wave infrared (SWIR) spectroscopy were used to identify mineralogical, geochemical and spectral vectors to alteration and mineralization, which may aid in future mineral exploration.

description: The thought of Gabriel Marcel (1889-1973) and Emmanuel Mounier (1905-1950) deeply influenced the philosophy of Paul Ricoeur (1913-2005). Marcel’s existential, concrete, incarnate person and his theory of intersubjectivity were foundational for Ricoeur’s understanding of personal identity, including his theses of the hermeneutic and narrative selves and the ethical, capable self. Mounier’s affirmation of the absolute value of the human person and his emphasis on community informed Ricoeur’s ethics. This thesis offers an original contribution to the field insofar as I am unaware of any work published thus far in English that addresses this topic. I will argue that Ricoeur expanded and refined Marcel’s vision of hope and Mounier’s dream of a caring community, carrying their aspirations to a practical end. In this way, he offers a realistic interpretation of the human condition and a model that provides authentic hope towards a future with justice for all.

description: The surface bound electronic states of three-dimensional topological insulators, as well as the edge states in two-dimensional topological insulators, are investigated in the presence of a circularly polarized light. The strong coupling between electrons and photons is found t o give rise to an energy gap as well as a unique energy dispersion of the dressed states, different from both graphene and conventional two-dimensional electron gas (2DEG). The effects of electron-photon interaction, barrier height and width on the electron tunneling through a p-n junction and on the ballistic conductance in topological insulators are demonstrated by numerical calculations. A critical energy for an incident electron to tunnel perfectly through a barrier is predicted, where electrons behave as either massless Dirac-like or massive Schrodinger-like particles above or below this threshold value. Additionally, these effects are compared with those in zigzag graphene nanoribbons and a 2DEG. Both the similarities and the differences are demonstrated and explained.

description: We investigate the thermodynamics of rotating Lovelock-Lifshitz black branes. We calculate the conserved and thermodynamic quantities of the solutions and obtain a relation between temperature, angular velocity, energy density, entropy density and angular momentum density. We, also, obtain a Smarr-type formula for the energy density as a function of entropy and angular momentum densities, and show that the thermodynamic quantities calculated in this paper satisfy the first law of thermodynamics. Finally, we investigate the stability of black brane solutions in both canonical and grand-canonical ensemble. We find that the solutions are thermally stable for the solutions with $z\leq n-1$, while they can be unstable for $z>n-1$.

We describe a scalable quantum information architecture based on micro-fabricated optical elements, simultaneously targeting the important issues of single-site addressability and scalability. This approach provides flexible and integrable configurations for quantum state storage, manipulation, and retrieval. We present recent experimental results on the initialization and coherent one-qubit rotation of up to 100 individually addressable qubits, the coherent transport of atomic quantum states in a scalable quantum shift register, and discuss the feasibility of two-qubit gates in 2D microtrap arrays.

description: We model asset prices with stochastic volatilities driven by fractional Brownian motion. Price paths and their endpoints are used to obtain a Monte Carlo value estimate of vanilla european options, lookback options as well as variance swaps. Underlying models for price movements are driven by stochastic volatility models driven by fractional Brownian motion with H > 1/2 . These models exhibit a strong autocorrelation in volatility evolution. The models considered are fractional Ornstein Uhlenbeck, fractional Cox-Ingersoll-Ross, fractional Continuous GARCH(1,1) and fractional Heston.

Contributions due to bulk states in the loop are known, so we focus on the contributions due to states localized at intersections of orientifold images. We show that these quantum corrections vanish. This does not follow from the usual nonrenormalization theorems of supersymmetric field theory.

description: Identifying differentially expressed (DE) genes associated with a sample characteristic is the primary objective of many microarray studies. As more and more studies are carried out with observational rather than well controlled experimental samples, it becomes important to evaluate and properly control the impact of sample heterogeneity on DE gene finding. Typical methods for identifying DE genes require ranking all the genes according to a preselected statistic based on a single model for two or more group comparisons, with or without adjustment for other covariates. Such single model approaches unavoidably result in model misspecification, which can lead to increased error due to bias for some genes and reduced efficiency for the others. We evaluated the impact of model misspecification from such approaches on detecting DE genes and identified parameters that affect the magnitude of impact. To properly control for sample heterogeneity and to provide a flexible and coherent framework for identifying simultaneously DE genes associated with a single or multiple sample characteristics and/or their interactions, we proposed a Bayesian model averaging approach which corrects the model misspecification by averaging over model space formed by all relevant covariates. An empirical approach is suggested for specifying prior model probabilities. We demonstrated through simulated microarray data that this approach resulted in improved performance in DE gene identification compared to the single model approaches. The flexibility of this approach is demonstrated through our analysis of data from two observational microarray studies.

description: The Lyme spirochete Borrelia burgdorferi causes the most prevalent vector-borne infection in North America. In this study, the importance of DNA metabolizing genes for the infectivity, persistence and survival to DNA damage in B. burgdorferi was determined. During the infection of a vertebrate host, B. burgdorferi undergoes antigenic variation by DNA recombination at vlsE, which encodes for an immunogenic surface lipoprotein required for the persistence of the spirochete. In the present study, eight gene targets were disrupted and only the RuvAB Holiday junction branch migrase subunits affected the switching at vlsE and the persistence of B. burgdorferi in mice. The disruption of these eight genes was part of a wider study aiming to identify nucleic acid metabolizing genes involved in switching at vlsE. Although no other genes were found to strongly affect switching, the disruption of the DEAH-box RNA helicase HrpA abolished the infectivity of B. burgdorferi. Since the complementation of hrpA in trans could not be achieved, the restoration of the wild-type gene by allelic exchange was used as an alternate strategy for complementation. The restoration of the wild-type hrpA did restore infectivity, confirming the importance of hrpA. Point mutations were also introduced by allelic exchange in motifs required for either the RNA helicase or the ATPase activity of HrpA. To avoid an intial screen of a large number of clones by sequencing, a strategy was adapted to confirm by PCR the presence of the mutation in the gene. Infection of mice with these B. burgdorferi hrpA mutants confirmed that the RNA helicase activity, in addition of the ATPase activity, is required for the survival of B. burgdorferi in the mouse. Finally, a strategy was adapted to expediently compare the cell density of multiple cultures. This strategy was used to measure the importance of 25 nucleic acid metabolizing genes for survival of B. burgdorferi to DNA damage. Using this strategy, the nucleotide excision repair pathway was shown to be the sole repair pathway to be significantly involved in repair of UV-induced DNA damage in B. burgdorferi.
Metal-rich accretion and thermohaline instabilities in exoplanets-host stars: consequences on the light elements abundances

description: The early evolution of planetary systems is expected to depend on various periods of disk matter accretion onto the central star, which may include the accretion of metal-rich matter after the star settles on the main sequence. When this happens, the accreted material is rapidly mixed within the surface convective zone and induces an inverse mean-molecular-weight gradient, unstable for thermohaline convection. The induced mixing, which dilutes the metal excess, may also have important consequences on the light elements abundances. We model and analyze this process, and present the results according to various possible accretion scenarios. We give a detailed discussion of the different ways of treating thermohaline mixing, as proposed by previous authors, and we converge on a consistent view, including the most recent numerical simulations. We show how the observations of light elements in stars can be used as tracers of such events.

Visuomotor adaptation : contributions of awareness, online correction, and sense of agency
Creators: name: Cameron, Brendan D.
Publisher: name: University of British Columbia

description: Our sensorimotor system constantly monitors its performance, checking that movements unfold as intended, and modifying motor commands when error creeps in. When a systematic change in the environment is imposed, such as a shift in the visual feedback of the limb, the sensorimotor system adapts to this change, such that when the perturbation is removed the system initially responds as though the perturbation were still present (so-called ‘aftereffects’). The current project investigates some of the factors that influence how the motor system responds when a systematic perturbation is introduced: How do awareness, explicit control, online control, and our sense of agency affect motor adaptation? To address these questions I apply two types of perturbation: perturbation of the target (Studies 1-3) and perturbation of visual feedback of the effector (Study 4). In Study 1, I investigate how a person’s awareness that a target has been perturbed influences how they learn from the reach error that this perturbation introduces. The study shows that awareness of a target perturbation dramatically undermines adaptation. In Study 2, I investigate how explicit control of a reaching movement influences adaptation to an unperceived target perturbation. The study shows that adaptation occurs even when participants are engaged in the explicit task of undershooting the target, suggesting that implicit motor processing can proceed while the system is busy with an explicit motor task. In Study 3, I investigate the influence of online error processing on reach adaptation, and I show that people adapt to a target perturbation regardless of whether error occurs during (online) or at the end of their reach. In Study 4, I investigate how a person’s agency over their movement influences how they learn from perturbed feedback. The study shows that a small amount of adaptation occurs when people have their limbs passively moved – a result of a shift in perceived limb location. The four studies, together, suggest that both error processing and sensory recalibration can contribute to aftereffects, but they also suggest that sensory feedback prediction during active reaching is the most important component of adaptation.

description: In this study, the nonlinear analysis of the sunspot index is embedded in the non-extensive statistical theory of Tsallis. The triplet of Tsallis, as well as the correlation dimension and the Lyapunov exponent spectrum were estimated for the SVD components of the sunspot index timeseries. Also the multifractal scaling exponent spectrum, the generalized Renyi dimension spectrum and the spectrum of the structure function exponents were estimated experimentally and theoretically by using the entropy principle included in Tsallis non extensive statistical theory, following Arimitsu and Arimitsu. Our analysis showed clearly the following: a) a phase transition process in the solar dynamics from high dimensional non Gaussian SOC state to a low dimensional non Gaussian chaotic state, b) strong intermittent solar turbulence and anomalous (multifractal) diffusion solar process, which is strengthened as the solar dynamics makes phase transition to low dimensional chaos in accordance to Ruzmaikin, Zeleny and Milovanov studies c) faithful agreement of Tsallis non equilibrium statistical theory with the experimental estimations of i) non-Gaussian probability distribution function, ii) multifractal scaling exponent spectrum and generalized Renyi dimension spectrum, iii) exponent spectrum of the structure functions estimated for the sunspot index and its underlying non equilibrium solar dynamics.

description: The human pathogens Neisseria meningitidis and N. gonorrhoeae express a receptor capable of binding to, and removing iron from, the host glycoprotein lactoferrin. Similar to the transferrin binding protein complex, the lactoferrin receptor consists of an integral outer membrane protein, lactoferrin binding protein A (LbpA), and a surface exposed bi-lobed lipoprotein, lactoferrin binding protein B (LbpB). Human gonococcal infection models have shown that possession of either lactoferrin or transferrin binding proteins are essential for survival, while possession of both receptors provides a competitive advantage during co-infection. This thesis identifies a novel function for LbpB showing that LbpB is capable of providing protection against human lactoferricin, a short cationic peptide derived from human lactoferrin. It further demonstrates that the protection by LbpB is mediated by two clusters of negatively charged amino acids that localize to exposed loops in the C-terminal lobe of LbpB, a region with no previously experimentally demonstrated function. In addition, this thesis demonstrates that the protection provided by LbpB in our assay system is underestimated, due to the activity of NalP, an outer membrane protein mediating proteolytic release of LbpB from the surface. An isogenic mutant lacking NalP activity has substantially enhanced protection in our assay, which is likely more representative of the activity of LbpB in vivo. In this study the negatively charged capsular polysaccharide is shown to confer a modest degree of protection against lactoferricin at lower concentrations of lactoferricin. This thesis also includes preliminary experiments demonstrating that protection mediated by LbpB can extend to other cationic antimicrobial peptides. Thus this study indicates that LbpB provides substantial protection against the antimicrobial peptide derived from human lactoferrin and may provide effective protection against similar elements of the innate host defense mechanisms.

description: We present a numerical method for solving Weyl's embedding problem which consists of finding a global isometric embedding of a positively curved and positive-definite spherical 2-metric into the Euclidean three space. The method is based on a construction introduced by Weingarten and was used in Nirenberg's proof of Weyl's conjecture. The target embedding results as the endpoint of an embedding flow in R^3 beginning at the unit sphere's embedding. We employ spectral methods to handle functions on the surface and to solve various (non)-linear elliptic PDEs. Possible applications in 3+1 numerical relativity range from quasi-local mass and momentum measures to coarse-graining in inhomogeneous cosmological models.
