Cerebral blood flow in heart transplant recipients at rest and during incremental exercise
Creators: name: Smirl, Jonathan David
Publisher: name: University of British Columbia
Year: 2012

description: Pathological impairments to cardiac output may impact cerebral blood flow (CBF). Prior studies on heart transplant recipients (HTR) have reported increases of 25-53% in CBF, 1-6 months following transplant. It is currently unknown if CBF is chronically altered in the years following transplant or during progressive exercise stress, when compared with aged-matched controls (AM). Donor population controls (DC) were included to determine if the responses observed in HTR are related to the age of the donor rather than the individual. The aim of this thesis was to examine the influence of long-term heart transplantation on the regulation of CBF velocity (CBFv) at rest and during incremental exercise. Two hypotheses were tested: 1) CBFv would be similar in HTR when compared to AM, but lower than DC; 2) that during incremental exercise, the HTR would have reduced elevations in CBFv compared with AM and DC. To address these hypotheses, HTR were tested who have a reported inability to acutely increase cardiac output during exercise. Seven male clinically stable HTR (62 ± 9 yrs of age, 9 ± 7 yrs post-transplant), seven male AM (62 ± 7 yrs), and seven male DC (22 ± 3 yrs) were recruited for this study. Bilateral middle cerebral arteries were insonated using transcranial Doppler ultrasound to obtain an index of CBFv. Data were obtained while seated and during an incremental cycling test to volitional exhaustion. A repeated measures ANOVA was applied to identify differences across exercise intensity. Comparisons between groups were performed with Fisher's LSD post hoc test. The main findings were: 1) Rest: CBFv was comparable between HTR and AM (40 vs. 41 cm/s), as expected, CBFv was 68% higher in the DC compared with the HTR and AM groups (P<0.05). 2) Incremental exercise: mean CBFv was not significantly different between the HTR and AM groups across any of the exercise intensities. In conclusion, the CBFv of long-term HTR are comparable to AM both at rest and during incremental exercise that despite a suppressed VO₂ Peak (and likely Q) CBFv is well maintained during incremental exercise in long – term HTR.
Introduction: What do we mean by 'transbordering Latin Americas'

Publisher: name: Columbia University

Subjects: Latin Americans

description: This book, Transbordering Latin Americas: Liminal Places, Cultures, and Powers (T)Here, explores transbordering/transnational Latin American sociocultural and spatial conditions across the globe and across scales—from the gendered and racialized body to the national and transnational arena. What do we mean by “transbordering Latin Americas”? When we use the plural Latin Americas, we purposefully implode the notion of a unified, cohesive, and static Latin America and a corresponding singular identity—a way of being or being perceived as Latin American. The phrase “transbordering Latin Americas” thus comprises instances of that which can be defined as “Latin American” (which is, in turn, open to debate and transformation), which occurs through plurilocal societal relations—existing within, between, and above the traditional container spaces of national and continental societies without clear or stable “motherlands” (Pries 2004; Irazábal, 2012). Latin Americas in plural aims to push further the problematization of “methodological nationalism,” or the tendency to liken society to the nation-state. Indeed, despite its continuous undeniable importance in framing social dynamics, the nation-state has been debunked as the “natural” unit of the modern world and particularly as a useful one for the study of migration and diasporic phenomena (Duany 2011; Wimmer and Glick Schiller 2002). This book suggests the need to go beyond not only “methodological nationalism” but also “methodological continentalism” to effectively deconstruct and reconstruct the notion of multiple and fluxing Latin Americas.
Search for decays of stopped, long-lived particles from 7 TeV pp collisions with the ATLAS detector

description: New metastable massive particles with electric and colour charge are features of many theories beyond the Standard Model. A search is performed for long-lived gluino-based R-hadrons with the ATLAS detector at the LHC using a data sample corresponding to an integrated luminosity of 31 pb^-1. We search for evidence of particles that have come to rest in the ATLAS detector and decay at some later time during the periods in the LHC bunch structure without proton-proton collisions. No significant deviations from the expected backgrounds are observed, and a cross-section limit is set. It can be interpreted as excluding gluino-based R-hadrons with masses less than 341 GeV at the 95% C.L., for lifetimes from 10^-5 to 10^3 seconds and a neutralino mass of 100 GeV.

description: The electrostatics properties of composite materials with fractal geometry are studied in the framework of fractional calculus. An electric field in a composite dielectric with a fractal charge distribution is obtained in the spherical symmetry case. The method is based on the splitting of a composite volume into a fractal volume $V_d\sim r^d$ with the fractal dimension $d$ and a complementary host volume $V_h=V_3-V_d$. Integrations over these fractal volumes correspond to the convolution integrals that eventually lead to the employment of the fractional integro-differentiation.
Effect of magnetocrystalline anisotropy on magnetocaloric properties of AlFe$_{2}$B$_{2}$ compound

description: It is well known that the temperature dependence of the effective magnetocrystalline anisotropy energy obeys the $l(l+1)/2$ power law of magnetization in the Callen-Callen theory. Therefore, according to the Callen-Callen theory, the magnetocrystalline anisotropy energy is assumed to be zero at the critical temperature where the magnetization is approximately zero. This study estimates the temperature dependence of the magnetocrystalline anisotropy energy by integrating the magnetization versus magnetic field ($M$--$H$) curves, and found that the magnetocrystalline anisotropy is still finite even above the Curie temperature in the uniaxial anisotropy, whereas this does not appear in the cubic anisotropy case. The origin is the fast reduction of the anisotropy field, which is the magnetic field required to saturate the magnetization along the hard axis, in the case of cubic anisotropy. Therefore, the magnetization anisotropy and anisotropic magnetic susceptibility, those are the key factors of magnetic anisotropy, could not be established in the case of cubic anisotropy. In addition, the effect of magnetocrystalline anisotropy on magnetocaloric properties, as the difference between the entropy change curves of AlFe$_{2}$B$_{2}$ appears above the Curie temperature, which is in good agreement with a previous experimental study. This is proof of magnetic anisotropy at slightly above Curie temperature.

description: For the thousands of refugee women who arrive in Canada annually speaking a language other than English, the language barrier is one of the most significant obstacles to integrating into Canadian society that they will face. To help facilitate the process, the Government of Canada offers free English classes called Language Instruction for Newcomers to Canada (LINC) to all newcomers. However, it has only been recently acknowledged that those who arrive might have little to no prior formal educational experience and as such will be largely illiterate in their mother tongues. This demographic will arrive needing help with both language and literacy and due to the nature of their situation, have been classified as ESL literacy students. Despite the seemingly daunting task of simultaneously having to acquire a new language along with first-time literacy skills, there are women who are working their way through LINC programs in Calgary, but little is known of them as a demographic. In this study, a methodology of narrative inquiry was used along with semi-structured interviews to gather the stories of seven women and from the interviews three main themes emerged: 1) The influence of past experiences; 2) Navigating new surroundings through language acquisition and literacy learning; and 3) Who am I now? Results of the study provide an overview of the motivations, challenges, perspectives and triumphs that these women have experienced and gained through engaging in classes as well as suggestions for improved practice in the developing field of ESL literacy.
The interaction between a spatially oscillating jet emitted by a fluidic oscillator and a cross-flow

description: This experimental study investigates the fundamental flow field of a spatially oscillating jet emitted by a fluidic oscillator into an attached cross-flow. Dominant flow structures, such as the jet trajectory and dynamics of streamwise vortices, are discussed in detail with the aim of understanding the interaction between the spatially oscillating jet and the cross-flow. The oscillating jet is ejected perpendicular to the cross-flow. A moveable stereoscopic particle image velocimetry (PIV) system is employed for the plane-by-plane acquisition of the flow field. The three-dimensional, time-resolved flow field is obtained by phase averaging the PIV results based on a pressure signal from inside the fluidic oscillator. The influence of velocity ratio and Strouhal number is assessed. Compared to a common steady wall-normal jet, the spatially oscillating jet penetrates to a lesser extent into the cross-flow’s wall-normal direction in favour of a considerable spanwise penetration. The flow field is dominated by streamwise-oriented vortices, which are convected downstream at the speed of the cross-flow. The vortex dynamics exhibits a strong dependence on the Strouhal number. For small Strouhal numbers, the spatially oscillating jet acts similar to a vortex-generating jet with a time-dependent deflection angle. Accordingly, it forms time-dependent streamwise vortices. For higher Strouhal numbers, the cross-flow is not able to follow the motion of the jet, which results in a quasi-steady wake that forms downstream of the jet. The results suggest that the flow field approaches a quasi-steady behaviour when further increasing the Strouhal number.

description: At least one neutrino has a mass of about 50 meV or larger. However, the absolute mass scale for the neutrino remains unknown. Furthermore, the critical question: Is the neutrino its own antiparticle? is unanswered. Studies of double beta decay offer hope for determining the absolute mass scale. In particular, zero-neutrino double beta decay (\BBz) can address the issues of lepton number conservation, the particle-antiparticle nature of the neutrino, and its mass. A summary of the recent results in \BBz, and the related technologies will be discussed in the context of the future \BBz\ program.

description: We discuss the coupled dynamics of the ghost dressing function and the ghost-gluon vertex through the Schwinger-Dyson equations that they satisfy. In order to close the system of equations, we combine recent lattice data for the gluon propagator and an approximate STI-derived Ansatz for the general kinematics three-gluon vertex. The numerical solution of the resulting coupled system exhibits excellent agreement to lattice data, for both the ghost dressing function and the ghost-gluon vertex, and allows the determination of the coupling constant. Next, in the soft gluon limit the full three-gluon vertex appearing in the ghost-gluon equation reduces to a special projection that is tightly constrained by lattice simulations. Specializing the ghost-gluon Schwinger-Dyson equation to this limit provides a nontrivial consistency check on the approximations employed for the three-gluon interaction and shows that the latter has an important quantitative effect on the ghost-gluon vertex. Finally, our results stress the importance of eliminating artifacts when confronting lattice data with continuum predictions.

description: Photonic integrated circuits (PICs) are expected to play a significant role in the ongoing second quantum revolution, thanks to their stability and scalability. Still, major upgrades are needed for available PIC platforms to meet the demanding requirements of quantum devices. In this paper, we present a review of our recent progress in upgrading an unconventional silicon photonics platform towards such goal, including ultra-low propagation losses, low fibre coupling losses, integration of superconducting elements, Faraday rotators, fast and efficient detectors, as well as phase modulators with low loss and/or low energy consumption. We show the relevance of our developments and of our vision in two main applications: quantum key distribution - to achieve significantly higher key rates and large-scale deployment - and cryogenic quantum computers - to replace electrical connections to the cryostat with optical fibres.

description: Determining the meaning or relevance of effort or exertion is a challenging endeavor for any field. The present research examined the relationship between a learner’s perceived level of mental exertion and the corresponding physiological responses. For the present study we measured physiological responses of cerebral blood velocity in the right middle cerebral artery, as well as respiration changes via measurement of end-tidal CO2 during learning tasks using static and dynamic images. The results from the present study show an overall difference in perceived mental effort between high and low spatial ability learners during learning with different types of digital media. Results suggest that there is an effect occurring between perceived mental effort and physiological response based on spatial ability. Patterns emerging from this research may be indicative of the need for a wider field of measurement in the brain. This study contributes to the understanding of cognitive load theory and the impact of digital learning materials on the learner. The use of subjective rating scales is strengthened with the inclusion of physiological data. We have also contributed to the development of theorizing how high and low spatial ability brains function during learning. Our results would help future studies that use more advanced neuroimaging make conclusions about what they may discover. Our results help to support the justification for using more advanced and costly methods as we have demonstrated the potential for some interaction occurring based on learner spatial ability.

description: Using the gauge/gravity correspondence, we study the properties of 2-point correlation functions of finite-temperature strongly coupled gauge field theories, defined on a curved space of general spatial topology with a dual black hole description. We derive approximate asymptotic expressions for the correlation functions and their poles, supported by exact numerical calculations, and study their dependence on the dimension of spacetime and the spatial topology. The asymptotic structure of the correlation functions depends on the relation between the spatial curvature and the temperature, and is noticeable when they are of the same order. In the case of a hyperbolic topology, a specific temperature is identified for which exact analytical solutions exist for all types of perturbations. The asymptotic structure of the correlation functions poles is found to behave in a non-smooth manner when approaching this temperature.

description: On any Reflection Equation algebra corresponding to a skew-invertible Hecke symmetry (i.e. a special type solution of the Quantum Yang-Baxter Equation) we define analogs of the partial derivatives. Together with elements of the initial Reflection Equation algebra they generate a "braided analog" of the Weyl algebra. When $q\to 1$, the braided Weyl algebra corresponding to the Quantum Group $U_q(sl(2))$ goes to the Weyl algebra defined on the algebra $\Sym((u(2))$ or that $U(u(2))$ depending on the way of passing to the limit. Thus, we define partial derivatives on the algebra $U(u(2))$, find their "eigenfunctions", and introduce an analog of the Laplace operator on this algebra. Also, we define the "radial part" of this operator, express it in terms of "quantum eigenvalues", and sketch an analog of the de Rham complex on the algebra $U(u(2))$. Eventual applications of our approach are discussed.

description: Audio sources frequently concentrate much of their energy into a relatively small proportion of the available time-frequency cells in a short-time Fourier transform (STFT). This sparsity makes it possible to separate sources, to some degree, simply by selecting STFT cells dominated by the desired source, setting all others to zero (or to an estimate of the obscured target value), and inverting the STFT to a waveform. The problem of source separation then becomes identifying the cells containing good target information. We treat this as a classification problem, and train a Relevance Vector Machine (a probabilistic relative of the Support Vector Machine) to perform this task. We compare the performance of this classifier both against SVMs (it has similar accuracy but is not as efficient as RVMs), and against a traditional Computational Auditory Scene Analysis (CASA) technique based on a noise-robust pitch tracker, which the RVM outperforms significantly. Differences between the RVM- and pitch-tracker-based mask estimation suggest benefits to be obtained by combining both.

description: The intersections of topology, geometry and strong correlations offer many opportunities for exotic quantum phases to emerge in condensed matter systems. Weyl fermions, in particular, provide an ideal platform for exploring the dynamical instabilities of single-particle physics under interactions. Despite its fundamental role in relativistic field theory, the concept of causality and the associated spacetime light cone and event horizon has not been considered in connection with interacting Weyl fermionic excitations in quantum matter. Here, by using charge-density wave (CDW) as an example, we unveil the behavior of interacting Weyl fermions and show that a Weyl fermion in a system can open a band gap by interacting only with other Weyl fermions that lie within its energy-momentum dispersion cone. In this sense, causal connections or interactions are only possible within overlapping dispersion cones and each dispersion cone thus constitutes a solid-state analogue of the more conventional `event horizon' of high-energy physics. Our study provides a universal framework for considering interacting relativistic quasiparticles in condensed matter by separating them into energy-like and momentum-like relationships in analogy with the time-like and space-like events in high-energy physics. Finally, we consider two different candidate materials for hosting the Weyl CDW phase: (TaSe$_4$)$_2$I and Mo$_3$Al$_2$C. Our study greatly enriches the phenomenology and unveils new connections between condensed matter and high-energy physics.

description: Simultaneous EEG-fMRI has been an effective technique for identification of the seizure onset zone (SOZ) in patients with refractory epilepsy. Recent studies have shown that using intracranial electrodes (iEEG) combined with fMRI offers unique insight into changes in blood oxygen-level dependent (BOLD) responses associated with interictal epileptiform discharges (IEDs). However, the concordance level between SOZ and IED-related BOLD clusters has not been quantitatively investigated for different brain structures. This thesis aims to identify patient-specific concordance levels between spike-associated BOLD clusters and IED/SOZ originating from temporal and extra-temporal structures. The distances between the BOLD clusters to IED/SOZ locations were measured for 15 patients with focal refractory epilepsy. The results showed that the spike-generating network was better delineated in patients with temporal discharges compared to those with extra-temporal discharges. Also, we observed shorter distances between the BOLD clusters and the SOZ for mesial temporal lobe seizures compared to frontal lobe seizures. Further investigation into the differences between mesial temporal and frontal structures showed that patients with focal impaired awareness seizures had significantly higher concordance for mesial temporal lobe seizures. This key finding suggests that mesial temporal structures limit spike-associated BOLD activation to the SOZ more than the frontal lobe in patients who have spread of ictal activity to subcortical arousal systems. This mechanistic difference was also complemented by our findings pertaining seizure frequency. Specifically, concordance levels in temporal lobe structures were significantly higher for patients with weekly seizures compared to extra-temporal structures. Based on these findings, we suggest that iEEG-fMRI is a useful technique for identifying seizure onset zone for patients with epileptic spikes and seizures originate in the mesial temporal structures. The work presented in this thesis may assist clinicians to better determine the seizure onset zone, guide epilepsy surgery, and improve post-surgical outcomes for epilepsy patients.

By building upon work in grounding free text against audio signals we invent an "automatic record review" system that labels new music audio with maximal semantic value for future retrieval tasks. In effect, we grow an unbiased music editor trained from the consensus of the online reviews we have gathered.

description: We study the boundary free energy of the XXZ spin-$\tf{1}{2}$ chain subject to diagonal boundary fields. We first show that the representation for its finite Trotter number approximant obtained by Bortz, Frahm and Göhmann is related to the partition function of the six-vertex model with reflecting ends. Building on the Tsuchiya determinant representation for the latter quantity we are able to take the infinite Trotter number limit. This yields a representation for the surface free energy which involves the solution of the non-linear integral equation that governs the thermodynamics of the XXZ spin-1/2 chain subject to periodic boundary conditions. We show that this integral representation allows one to extract the low-$T$ asymptotic behavior of the boundary magnetization at finite external magnetic field on the one hand and numerically plot this function on the other hand.

description: Chord sequences are a compact and useful description of music, representing each beat or measure in terms of a likely distribution over individual notes without specifying the notes exactly. Transcribing music audio into chord sequences is essential for harmonic analysis, and would be an important component in content-based retrieval and indexing, but accuracy rates remain fairly low. In this paper, the existing 2008 LabROSA Supervised Chord Recognition System is modified by using different machine learning methods for decoding structural information, thereby achieving significantly superior results. Specifically, the hidden Markov model is replaced by a large margin structured prediction approach (SVMstruct) using an enlarged feature space. Performance is significantly improved by incorporating features from future (but not past) frames. The benefit of SVMstruct increases with the size of the training set, as might be expected when comparing discriminative and generative models. Without yet exploring non-linear kernels, these improvements lead to state-of-the-art performance in chord transcription. The techniques could prove useful in other sequential learning tasks which currently employ HMMs.

Iwasawa theory of Heegner points on abelian varieties of GL_2 type
Creators: name: Howard, Benjamin
Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: In an earlier paper the author proved one divisibility of Perrin- Riou's Iwasawa main conjecture for Heegner points on elliptic curves. In the present paper, that result is generalized to abelian varieties of GL2-type (i.e. abelian varieties with real multiplication defined over totally real fields) under the hypothesis that the abelian variety is associated to a Hilbert modular form via a construction of Zhang.

description: Technical debt refers to taking shortcuts to achieve short-term goals while sacrificing the long-term maintainability and evolvability of software systems. A large part of technical debt is explicitly reported by the developers themselves; this is commonly referred to as Self-Admitted Technical Debt or SATD. Previous work has focused on identifying SATD from source code comments and issue trackers. However, there are no approaches available for automatically identifying SATD from other sources such as commit messages and pull requests, or by combining multiple sources. Therefore, we propose and evaluate an approach for automated SATD identification that integrates four sources: source code comments, commit messages, pull requests, and issue tracking systems. Our findings show that our approach outperforms baseline approaches and achieves an average F1-score of 0.611 when detecting four types of SATD (i.e., code/design debt, requirement debt, documentation debt, and test debt) from the four aforementioned sources. Thereafter, we analyze 23.6M code comments, 1.3M commit messages, 3.7M issue sections, and 1.7M pull request sections to characterize SATD in 103 open-source projects. Furthermore, we investigate the SATD keywords and relations between SATD in different sources. The findings indicate, among others, that: 1) SATD is evenly spread among all sources; 2) issues and pull requests are the two most similar sources regarding the number of shared SATD keywords, followed by commit messages, and then followed by code comments; 3) there are four kinds of relations between SATD items in the different sources.

description: Human norovirus (NV) and hepatitis C virus (HCV) are two major and related human pathogens belonging to the positive-strand RNA virus superfamily. NV belongs in the Caliciviridae family and is a major cause of gastroenteritis outbreaks throughout the world. Although there is substantial interest in the development of vaccines and antiviral therapeutics for norovirus infections, there are currently no effective antiviral treatments. Using a fluorescence-based primer extension assay, I have identified a series of structurally-related compounds that inhibit norovirus polymerase at micromolar concentrations. Previous work in our group has helped to structurally characterize human norovirus polymerase complexes with RNA, nucleoside triphosphates, and divalent metal ions. These structures have revealed the enzyme trapped indifferent conformations that are likely important for the catalytic cycle. Several enzyme-inhibitor complexes with alendronic acid and medronic acid inhibitors have been crystallized, and the structure determination of NV Pol complexes has been undertaken. This thesis presents new results correlating enzyme inhibition kinetics with crystallographic structure determination for several novel inhibitor complexes. In the second part of this thesis, work is described on characterizing interactions between RNA and HCV non-structural protein NS5B, the RNA-dependent RNA Polymerase (RDRP) central to HCV replication. HCV NS5B is highly-conserved and forms the core of the catalytic site of the replicase complex. I have determined the structure of a novel polymerase-RNA complex that shows the binding of a short RNA oligonucleotide to a region of the enzyme near a commonly-targeted site for the binding of allosteric inhibitors.

description: Compost is used worldwide as a soil conditioner for crops, but its functions have still been explored. Here, the omics profiles of carrots were investigated, as a root vegetable plant model, in a field amended with compost fermented with thermophilic Bacillaceae for growth and quality indices. Exposure to compost significantly increased the productivity, antioxidant activity, red color, and taste of the carrot root and altered the soil bacterial composition with the levels of characteristic metabolites of the leaf, root, and soil. Based on the data, structural equation modeling (SEM) estimated that L-2-aminoadipate, phenylalanine, flavonoids and / or carotenoids in plants were optimally linked by exposure to compost. The SEM of the soil estimated that the genus Paenibacillus, L-2-aminoadipate and nicotinamide, and S-methyl L-cysteine were optimally involved during exposure. These estimates did not show a contradiction between the whole genomic analysis of compost-derived Paenibacillus isolates and the bioactivity data, inferring the presence of a complex cascade of plant growth-promoting effects and modulation of the nitrogen cycle by compost itself. These observations have provided information on the qualitative indicators of compost in complex soil-plant interactions and offer a new perspective for chemically independent sustainable agriculture through the efficient use of natural nitrogen.
