description: Radio-frequency ablation (rfa) is the standard of care for the treatment of cardiac arrhythmias; however, there are no direct measures of the successful delivery of ablation lesions. Optical coherence tomography (OCT) imaging has the potential to provide real-time monitoring of cardiac rfa therapy, visualizing lesion formation and assessing tissue contact in the presence of blood. A rfa-compatible forward-imaging conical scanning probe is prototyped to meet this need. The forward-imaging probe provides circular scanning, with a 2-mm scan diameter and 30-μm spot size. During the application of rf energy, dynamics are recorded at 20framespersecond with a 40-kHz A-line rate. Real-time monitoring of cardiac rfa lesion formation and imaging in the presence of blood is demonstrated ex vivo in a swine left ventricle with a forward, flexible, circular scanning OCT catheter.

description: We report on first-principles calculations of the side-jump contribution to the anomalous Hall conductivity (AHC) directly from the electronic structure of a perfect crystal. We implemented our approach for a short-range scattering disorder model within the density functional theory and computed the full scattering-independent AHC in elemental bcc Fe, hcp Co, fcc Ni, and L1o FePd and FePt alloys. The full AHC thus calculated agrees systematically with experiment to a degree unattainable so far, correctly capturing the previously missing elements of side-jump contributions, hence paving the way to a truly predictive theory of the anomalous Hall effect and turning it from a characterization tool to a probing tool of multi-band complex electronic band structures.

Sources of inductive signals patterning the x. laevis pronephros
Creators: name: White, Caroline
Publisher: name: University of Calgary
Year: 2011

description: Bibliography: p. 100-111
description: Despite a thorough understanding of the target genes and factors regulated in response to inductive signalling in the kidney, little is known about the identities or sources of the inductive signals themselves. Previously, most studies have focused on the pronephric tubules, overlooking the other two functional components of the embryonic kidney. The tubules, glomus and duct are capable of forming independently and their development involves different downstream signalling pathways, making it likely that these components respond to inductive signals from different sources. Here that possibility is tested by observing the formation of all three pronephric components in the presence or absence of potential inducing tissues. These data demonstrate the need to consider the functional components of the pronephros individually when researching the sources of inductive signals patterning this organ, and identify anterior neural tissue as a primary candidate source of signals responsible for induction of the duct and glomus.

description: Heterogeneity in cardiac tissue microstructure is a potential mechanism for the generation and maintenance of arrhythmias. Abnormal changes in fiber orientation increase the likelihood of arrhythmia. We present optical coherence tomography (OCT) as a method to image myofibers in excised intact heart preparations. Three-dimensional (3-D) image sets were gathered from the rabbit right ventricular free wall (RVFW) using a microscope-integrated OCT system. An automated algorithm for fiber orientation quantification in the plane parallel to the wall surface was developed. The algorithm was validated by comparison with manual measurements. Quantifying fiber orientation in the plane parallel to the wall surface from OCT images can be used to help understand the conduction system of the specific sample being imaged.

description: Theoretical studies of the production of real thermal photons in relativistic heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) are performed. The space-time evolution of the colliding system is modelled using MUSIC, a 3+1D relativistic hydrodynamic simulation, using both its ideal and viscous versions. The inclusive spectrum and its azimuthal angular anisotropy are studied separately, and the relative contributions of the different photon sources are highlighted. It is shown that the photon v2 coefficient is especially sensitive to the details of the microscopic dynamics like the equation of state, the ratio of shear viscosity over entropy density, eta/s, and to the morphology of the initial state.

Becoming a knowledge society: State of Qatar rationales for importation of a North American branch campus model of higher education in Qatar
Creators: name: Walsh, Pamela

Year: 2011

description: Bibliography: p. 231-253
description: Qatar is an Arab Islamic country, formerly poor and with a history of formal education that only dates back to the 1950s. Over the past two decades its economy has emerged as one of the fastest growing in the world and it has one of the highest per capita incomes in the world. This study looked the State of Qatar's rationales for choosing a North American transnational branch campus model of higher education for Qatar, as well as the challenges associated with the operations and governance of the model. Seven North American branch campuses were included in the study. Six of these were American university branch campuses within Education City in Qatar and one was a Canadian technical college branch campus located outside Education City in Qatar. The study employed constructivist grounded theory as the methodology for investigating the rationales for the establishment of the model as well as the challenges associated with the operations and governance of the model. Open-ended interviews as well as extant texts were used to generate data for the study. Six rationales for the branch campus model emerged from the data. These rationales fall within a typology of rationales that are academic, socio-cultural, economic, and political. Challenges that emerged from the participant data were English language proficiency of students, socio-cultural issues, and issues related to the operations and governance of the model itself. Factors deemed necessary for success of the model are also briefly discussed. A theory was generated in this study through systematic collection and an analysis of data regarding the nature of Qatar's rationales for importing a North American branch campus model of higher education for its people.

description: Electrical resistivity surveys were conducted of an unconfined fluvial aquifer in Columbus, MS. The aquifer consists of an upper 3 m thick clayey-silt flood plain facies containing clay and silty-clay filled channels and a lower 5 m thick braided stream facies consisting of sand and gravelly-sand. A survey conducted in 2002 imaged the aquifer in a drained state. It was re-surveyed in 2004 when saturated. The geometry and positions of the two surveys are identical, so changes in resistivity are a direct result of aquifer saturation. The data was inverted to produce cross sections of resistivity in the saturated and drained aquifer. The difference in resistivity shows that water saturation decreases resistivity in the upper flood plain facies by 0 to 600 ohm-m, with the creates change outside the channels in the clayey-silt flood plain deposits. In the channels, the resistivity remains approximately unchanged. This is attributed to the low permeability of the clay, which does not allow water to enter the channel fill. In the braided stream facies, resistivity increases with saturation by 0 to 1100 ohm-m. The largest increases are in the poorly sorted gravel-bearing deposits. Channels and major lithologic boundaries are well constrained in both the saturated and unsaturated state, indicating that resistivity images of drained outcrops provide a reliable analog that can be used for interpretation of data from buried, saturated aquifers.

description: We consider spinfoam quantum gravity on a spacetime decomposition with many 4-simplices, in the double scaling limit in which the Immirzi parameter $γ$ is sent to zero (flipped limit) and the physical area in Planck units ($γ$ times the spin quantum number $j$) is kept constant. We show that the quantum amplitude takes the form of a Regge-like path integral and enforces Einstein equations in the semiclassical regime. In addition to quantum corrections which vanish when the Planck constant goes to zero, we find new corrections due to the discreteness of geometric spectra which is controlled by the Immirzi parameter.

Publisher: name: University of Calgary
Year: 2011

description: Bibliography: p. 121-132
description: Some geomechanical properties of the Montney shale were investigated experimentally in this study. From the Brazilian and point load strength tests, the tensile strength in the horizontal direction was dominated by the bond strength of the intact structure (6 -15.3 MPa), whereas that in the vertical direction was controlled by the existing natural beddings (0.7-2.8 MPa). Compressive strength, compressive elastic modulus in the vertical direction and the Poisson' s ratio were measured from the unconfined compressive strength test as 99 MPa, 25 GPa, and 0.1, respectively. Tensile and compressive elastic moduli in the horizontal direction were measured from Brazilian test as 31 GPa and 40 GPa, respectively. From the shear test results, the cohesion was found as 2 MP a and the peak friction angle was about 40°. From this study it was found that the pre-existing planes of weakness play a major role in failure and anisotropic behavior of the Montney shale.

description: We propose a theoretical formalism to evaluate the entropy density and entropy flux that takes into account near-field effects, i.e., interference, diffraction, and tunneling of waves. Using the fluctuation-dissipation theorem, expressions for entropy density and entropy flux in a vacuum cavity between planar multilayered media are derived in terms of local density of photons, local density of accessible microscopic states, and velocity of energy transmission. The proposed method is used to determine the maximum work that can be extracted and a thermodynamic limit of the energy conversion efficiency that can be obtained in near-field thermal radiation.

description: We present details of the construction and characterization of the coaddition of the Sloan Digital Sky Survey Stripe 82 \ugriz\ imaging data. This survey consists of 275 deg$^2$ of repeated scanning by the SDSS camera of $2.5\arcdeg$ of $δ$ over $-50\arcdeg \le α\le 60\arcdeg$ centered on the Celestial Equator. Each piece of sky has $\sim 20$ runs contributing and thus reaches $\sim2$ magnitudes fainter than the SDSS single pass data, i.e. to $r\sim 23.5$ for galaxies. We discuss the image processing of the coaddition, the modeling of the PSF, the calibration, and the production of standard SDSS catalogs. The data have $r$-band median seeing of 1.1\arcsec, and are calibrated to $\le 1%$. Star color-color, number counts, and psf size vs modelled size plots show the modelling of the PSF is good enough for precision 5-band photometry. Structure in the psf-model vs magnitude plot show minor psf mis-modelling that leads to a region where stars are being mis-classified as galaxies, and this is verified using VVDS spectroscopy. As this is a wide area deep survey there are a variety of uses for the data, including galactic structure, photometric redshift computation, cluster finding and cross wavelength measurements, weak lensing cluster mass calibrations, and cosmic shear measurements.

description: The current understanding of the earthquake interevent times distribution (ITD) is incomplete. The Weibull distribution is often used to model the earthquake ITD. We link the earthquake ITD on single faults with the Earth's crustal shear strength distribution by means of a phenomenological stick - slip model. We obtain Weibull ITD for power-law stress accumulation, i.e., $σ(t) = αt^β$, where $β>0$ for single faults or systems with homogeneous strength statistics. We show that logarithmic stress accumulation leads to the log-Weibull ITD. For the Weibull ITD, we prove that (i) $m= βm_s$, where $m$ and $m_s$ are, respectively, the ITD and crustal shear strength Weibull moduli and (ii) the time scale $τ_s = (S_s/α)^{1/β}$ where $S_s$ is the scale of crustal shear strength. We generalize the ITD model for fault systems. We investigate deviations of the ITD tails from the Weibull due to sampling bias, magnitude selection, and non-homogeneous strength parameters. Assuming the Gutenberg - Richter law and independence of $m$ on the magnitude threshold, $M_{L,c},$ we deduce that $τ_s \propto e^{- ρ_{M} M_{L,c}},$ where $ρ_M \in [1.15, 3.45]$ for seismically active regions. We demonstrate that a microearthquake sequence conforms reasonably well to the Weibull model. The stochastic stick - slip model justifies the Weibull ITD for single faults and homogeneous fault systems, while it suggests mixtures of Weibull distributions for heterogeneous fault systems. Non-universal deviations from Weibull statistics are possible, even for single faults, due to magnitude thresholds and non-uniform parameter values.

Promoting reading skills of young adult EAL learners through voice recognition software
Creators: name: D'Silva, Reginald Arthur
Publisher: name: University of British Columbia

description: The growing international student population in post-secondary institutions in Canada calls for Academic Exchange Programs (AEPs) to focus on promoting reading skills of English as an Additional Language (EAL) students in order to help them read academic and non-academic texts more proficiently. The current study, conducted at a major western Canadian university, investigated the effectiveness of a computer-based software program called the Reading Tutor (RT) in enhancing the reading performance of EAL young adults. A survey determined the reading preferences of participants and reading materials related to news articles were incorporated into the software. Two experimental groups, one (n=16) that self-reported a preference and the other that self-reported a non-preference (n=12) for such reading materials used the software over a period of eight weeks. A control group (n=14) served as a comparison. Results showed that a preference for reading materials positively influenced the non-transfer and transfer of reading fluency skills for non-academic reading materials in a computer-based environment. These skills also transferred to academic texts. However, the gain in reading fluency did not result in gains in comprehension. There was also a positive gain in how students self-assessed their ability to read in English in both of the experimental groups when compared to the control group. The survey also probed reading habits and found that students were in concentric domains of ESL and EFL, spending a majority of their time mainly reading in English for academic purposes. Reading for pleasure in English was only a small part of the students’ reading repertoire. The model of Concentric Domains of Instructional Environments (CDIE) stemming from these results suggests that AEPs, such as the one in the current study, may benefit from reading programs that incorporate extensive reading of non-academic reading materials. There appears to be a small number of studies investigating the effectiveness of computer-based literacy tools in promoting reading skills, among university EAL learners. This study makes a unique and valuable contribution to the understanding of such tools in promoting reading skills with student-preferred materials. In addition, the study adds to the understanding of reading habits of Japanese students in AEPs.

description: We present and analyze a multigrid algorithm for the acoustic single layer equation in two dimensions. The boundary element formulation of the equation is based on piecewise constant test functions and we make use of a weak inner product in the multigrid scheme as proposed in \cite{BLP94}. A full error analysis of the algorithm is presented. We also conduct a numerical study of the effect of the weak inner product on the oscillatory behavior of the eigenfunctions for the Laplace single layer operator.

description: Seismostratigraphy, coring, and logging while drilling during Integrated Ocean Drilling Program Expeditions 319, 322, and 333 (Sites C0011/C0012) show three Miocene submarine fans in the NE Shikoku Basin, with broadly coeval deposits at Ocean Drilling Program Site 1177 and Deep Sea Drilling Project Site 297 (NW Shikoku Basin). The sediment dispersal patterns have major implications for paleogeographies at that time. The oldest, finer-grained (Kyushu) fan has sheet-like geometry; quartz-rich flows were fed mostly from an ancestral landmass in the East China Sea. During prolonged hemipelagic mud deposition at C0011-C0012 (~12.2 to 9.1 Ma), sand supply continued at Sites 1177 and 297. Sand delivery to much of the Shikoku Basin halted during a phase of sinistral strike slip to oblique plate motion, after which the Daiichi Zenisu Fan (~9.1 to 8.0 Ma) was fed by submarine channels. The youngest fan (Daini Zenisu; ~8.0 to 7.6 Ma) has sheet-like geometry with thick-bedded, coarse-grained pumiceous sandstones. The pumice fragments were fed from a mixed provenance that included the collision zone of the Izu-Bonin and Honshu Arcs. The shift from channelized to sheet-like flows was favored by renewal of relatively rapid northward subduction, which accentuated the trench as a bathymetric depression. Increased sand supply appears to correlate with long-term eustatic lowstands of sea level. The stratigraphic position and 3-D geometry of the sandbodies have important implications for subduction-related processes, including the potential for focused fluid flow and fluid overpressures above and below the plate boundary fault: In sheet-like sands, pathways for fluid flow have greater horizontal permeability compared with those in channel sands.

description: The knowledge of the propagation of flood waves, in natural channels, through Saint Venant's equations, has been object of studies on the part of engineers and scientists, along years. With the progress of the digital computers, the mathematical models become a great option, in the analysis of this class problem. In this context, the uses of numerical models, in the treatment of the hydrodynamic models, has allowed more select studies of the behavior of the flood routing to be accomplished. This work treats of the study of a flood wave, through a simplified methodology, for solution of the equations of the hydrodynamic that allows the use of a numerical model with explicit solution. The influence of hydraulic parameters, inherent to the natural river, it is considered. The results show that this methodology had a great acting and it constitutes in a good way for the study of this class of problem.

description: This work studies the association between welfare reform, broadly defined to include an array of social policy changes affecting low‐income families in the 1990s, and expenditure patterns of poor single‐mother families. The findings suggest that welfare reform is not associated with any statistically significant change in total expenditures in families headed by low‐educated single mothers. However, patterns of expenditure changed. The reform policy is associated with an increase in spending on transportation and food away from home, as well as on adult clothing and footwear. In contrast, it is not related to changes in expenditures on child care or learning and enrichment activities. The pattern of results suggests that welfare reform has shifted family expenditures toward items that facilitate work outside the home but, at least so far, does not allow low‐income families to catch up with more advantaged families in expenditures on learning and enrichment.
Assessing the accuracy of using biplanar radiography combined with computed tomography to estimate cartilage deformation in the hip

description: Excessive or abnormal joint loading that leads to cartilage degeneration has been associated with hip osteoarthritis (OA). Before preventative measures for OA can be designed, such as physiotherapy techniques, braces, or surgical interventions, the connection between load-bearing and cartilage degeneration needs to be validated experimentally. As a first step towards such a validation, a method of measuring the load distribution across the hip joint is needed; ideally that can be used in vivo and can detect changes in the load distribution during an applied load. The objective of this study was to assess the accuracy of using biplanar radiography combined with CT imaging to estimate hip cartilage strain across the joint as an indication of the load distribution. Estimating cartilage strain using biplanar radiography and CT imaging is a multi-device multi-step measurement protocol that has error associated with each step. While biplanar radiography systems are commonly assessed on their ability to measure radio-opaque bead locations, to the author’s knowledge no studies have quantified errors in the additional steps of estimating cartilage strain. The present study used a phantom hip joint to quantify the errors in measuring bone displacement with biplanar radiography, segmenting 3D joint surfaces from a CT image, and measuring the relative proximity of joint surfaces in the biplanar radiography coordinate frame. The quantified errors were much lower than ex vivo hip cartilage deformation results in the literature, which demonstrated the potential for using this technique to estimate cartilage strain in the hip. As a proof of concept, cartilage strain was estimated in the ex vivo hip joint during a compressive load. Two hemi-pelvis/proximal femur specimens, with radio-opaque beads inserted in each bone, were loaded in compression in a materials testing machine, with biplanar radiographs acquired throughout. A small amount of cartilage deformation (0.1mm) was detected across the hip joint; however, due to the low load applied the deformation results were not comparable to the literature. The largest cartilage strains were identified in the anterior and superior regions, which was consistent with the literature. Future studies using higher loads are needed to further assess the capabilities of our system.

Spherically Averaging Ellipsoidal Galaxy Clusters in X-Ray and Sunyaev-Zel'dovich Studies: I. Analytical Relations

description: This is the first of two papers investigating the deprojection and spherical averaging of ellipsoidal galaxy clusters. We specifically consider applications to hydrostatic X-ray and Sunyaev-Zel'dovich (SZ) studies, though many of the results also apply to isotropic dispersion-supported stellar dynamical systems. Here we present analytical formulas for galaxy clusters described by a gravitational potential that is a triaxial ellipsoid of constant shape and orientation. For this model type we show that the mass bias due to spherically averaging X-ray observations is independent of the temperature profile, and for the special case of a scale-free logarithmic potential, there is exactly zero mass bias for any shape, orientation, and temperature profile. The ratio of spherically averaged intracluster medium (ICM) pressures obtained from SZ and X-ray measurements depends only on the ICM intrinsic shape, projection orientation, and H_0, which provides another illustration of how cluster geometry can be recovered through a combination of X-ray and SZ measurements. We also demonstrate that Y_SZ and Y_X have different biases owing to spherical averaging, which leads to an offset in the spherically averaged Y_SZ - Y_X relation. A potentially useful application of the analytical formulas presented is to assess the error range of an observable (e.g., mass, Y_SZ) accounting for deviations from assumed spherical symmetry, without having to perform the ellipsoidal deprojection explicitly. Finally, for dedicated ellipsoidal studies, we also generalize the spherical onion peeling method to the triaxial case for a given shape and orientation.

description: Currently, cardiac radiofrequency ablation (RFA) is guided by indirect signals. We demonstrate optical coherence tomography (OCT) characterization of RFA lesions within swine ventricular wedges. Untreated tissue exhibited a consistent birefringence artifact within OCT images due to the organized myocardium, which was not present in treated tissue. Birefringence artifacts were detected by filtering with a Laplacian of Gaussian (LoG) to quantify gradient strength. The gradient strength distinguished RFA lesions from untreated sites (p=5.93×10-15) with a sensitivity and specificity of 94.5% and 86.7% respectively. This study demonstrates the potential of OCT for monitoring cardiac RFA, confirming lesion formation and providing feedback to avoid complications.
Stratégies matrimoniales et émigration vers l'Amérique au 18e siècle: la maison Berrio de La Bastide Clairence

description: Avant l'émigration de masse vers l'Amérique du Sud au 19e siècle, les communautés rurales des Pyrénées occidentales connurent un mouvement migratoire notable vers Saint-Domingue et les autres îles des Caraïbes. Cet article porte sur les rapports entre les mouvements migratoires et l'organisation de ces communautés en « sociétés à maisons » (Lévi-Strauss) où la continuité de la « maison » était essentielle, et aucune nouvelle maison ne pouvait être fondée. Etudiant de près le cas d'une maison, on analyse le rôle complexe des coutumes successorales dans la décision d'émigrer, et on reconstruit les réseaux qui permirent l'émigration. Loin de l'image traditionnelle du fils forcé de partir parce que privé de sa part d'héritage, on montre que l'émigration des cadets avait le soutien de l'ensemble du groupe familial. On fait voir aussi que vis-à-vis du « système à maisons », l'émigration était tout à la fois une conséquence du système et contraire à l'esprit du système.

description: Orbital observations of Mercury by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft provide new constraints on that planet's thermal and interior evolution. Specifically, MESSENGER observations have constrained the rate of radiogenic heat production via measurement of uranium, thorium, and potassium at the surface, and identified a range of surface compositions consistent with high-temperature, high-degree partial melts of the mantle. Additionally, MESSENGER data have placed new limits on the spatial and temporal variation in volcanic and tectonic activity and enabled determination that the planet's core is larger than previously estimated. Because Mercury's mantle layer is also thinner than previously thought, this result gives greater likelihood to the possibility that mantle convection is marginally supercritical or even that the mantle is not convecting. We simulate mantle convection and magma generation within Mercury's mantle under two-dimensional axisymmetry and a broad range of conditions to understand the implications of MESSENGER observations for the thermal evolution of the planet. These models demonstrate that mantle convection can persist in such a thin mantle for a substantial portion of Mercury's history, and often to the present, as long as the mantle is thicker than ~300 km. We also find that magma generation in Mercury's convecting mantle is capable of producing widespread magmas by large-degree partial melting, consistent with MESSENGER observations of the planet's surface chemistry and geology.

description: Using a stochastic differential equation (SDE) approach, we examine the dynamics of the continental-scale water balance in the central United States. White-noise and colored-noise versions of the model are developed based on analysis of atmospheric data from the National Center for Environmental Prediction (NCEP) re-analysis project and long-term records of precipitation and soil moisture. Improved correspondence to observations is achieved by inclusion of terms in the SDE representing both hydrodynamic and thermodynamic soil-moisture feedbacks. We show that temporally correlated (i.e., colored) atmospheric moisture flux removes the bimodality of the soil moisture probability distribution and that our colored-noise formulation successfully captures the water balance dynamics in the study region despite the absence of multiple soil moisture states. Specifically, the improved model reproduces both the autocorrelation structure and the inter-annual variability in the observations.
