description: Using a generalized parton model approach including spin and intrinsic parton motion effects, and assuming the validity of factorization for large p_T jet production in hadronic collisions, we study the azimuthal distribution around the jet axis of leading pions, produced in the jet fragmentation process. We identify the observable leading-twist azimuthal asymmetries for the unpolarized and single-polarized case related to both quark and gluon-originated jets. We account for all physically allowed combinations of the transverse momentum dependent (TMD) parton distribution and fragmentation functions, with special attention to the Sivers, Boer-Mulders, and transversity quark distributions, and to the Collins fragmentation function for quarks (and to the analogous functions for gluon partons).

description: The aim of this study was to determine the strengths of the coupling of electrons with the polar long-wavelength transverse optical (TO) vibrations from infrared spectroscopy data. This determination is made by means of a simple relationship between the electron-TO-phonon interaction constant and material parameters, based on a parametrization of the electron-TO-phonon coupling in terms of the long-range dipole-dipole interaction. The combination of experimental data employed here allowed us to calculate directly the relevant constants for a number of representative polar insulators and to show that in ferroelectrics the interband electron-TO-phonon interaction at the Gamma point is essentially strong. In these calculations, infrared spectroscopy methods proved to be an effective tool for study of the main properties of electron interaction with polar long-wavelength TO phonons.

description: The Knapsack Problem is a classic problem in combinatorial optimisation. Solving these problems may be computationally expensive. Recent years have seen a growing interest in the use of deep learning methods to approximate the solutions to such problems. A core problem is how to enforce or encourage constraint satisfaction in predicted solutions. A promising approach for predicting solutions to constrained optimisation problems is the Lagrangian Dual Framework which builds on the method of Lagrangian Relaxation. In this paper we develop neural network models to approximate Knapsack Problem solutions using the Lagrangian Dual Framework while improving constraint satisfaction. We explore the problems of output interpretation and model selection within this context. Experimental results show strong constraint satisfaction with a minor reduction of optimality as compared to a baseline neural network which does not explicitly model the constraints.
Elucidating the neurobiology and individual differences of cost/benefit decision making using a novel rat task of cognitive effort
Creators: name: Hosking, Jeremy G.
Publisher: name: University of British Columbia
Year: 2014

description: Amotivational states and insufficient recruitment of mental effort have been observed in a variety of clinical populations, including depression, traumatic brain injury, post-traumatic stress disorder, and attention-deficit/hyperactivity disorder. Previous animal models of effort-based decision making have utilized physical costs whereas human studies of effort have been primarily cognitive in nature, and it is unclear whether the two types of effortful decision making are underpinned by the same neurobiological processes. We therefore validated a novel rat Cognitive Effort Task (rCET) based on the five-choice serial reaction-time task, a well-established measure of attention and impulsivity. Within each rCET trial, rats were given the choice between an easy or hard visuospatial discrimination, and successful hard trials were rewarded with double the number of sugar pellets. Similar to previous human studies, stable individual variation in choice behaviour was observed, with “workers” choosing hard trials significantly more than their “slacker” counterparts. We used a variety of pharmacological agents as well as temporary inactivation of select brain regions, and showed that the effects of these manipulations often interacted with animals’ baseline preferences. Amphetamine and caffeine caused workers to “slack off”, whereas slackers “worked harder” under amphetamine but not caffeine. Dopamine antagonism had no discernible effects on animals’ choice, contrary to the physical-effort literature. The cholinergic drug nicotine decreased slackers’ willingness to expend effort, whereas scopolamine more substantially decreased workers’ choice of the high-effort option. Temporary inactivation of the basolateral amygdala caused workers to slack off and slackers to work harder, whereas anterior cingulate and medial prefrontal cortex inactivations caused all animals to slack off. In sum, we have shown for the first time that rats are differentially sensitive to cognitive effort when making decisions, independent of other processes such as impulsivity, and these baseline differences appear to be reflected by differences in underlying neurobiology. Further, we demonstrate that mental and physical effort are in part dissociable, both behaviourally and in terms of neurochemistry and neural circuitry. Such findings could inform our understanding of the neurobiological basis of decision making as well as impairments in effort-based decision making, and may contribute to novel therapeutic interventions.

description: We compare, through first-principles pseudopotential calculations, the structural, electronic and optical properties of different size silicon nanoclusters embedded in a SiO2 crystalline or amorphous matrix, with that of free-standing, hydrogenated and hydroxided silicon nanoclusters of corresponding size and shape. We find that the largest effect on the opto-electronic behavior is due to the amorphization of the embedded nanocluster. In that, the amorphization reduces the fundamental gap while increasing the absorption strength in the visible range. Increasing the nanocluster size does not change substantially this picture but only leads to the reduction of the absorption threshold, following the quantum confinement rule. Finally, through the calculation of the optical absorption spectra both in a indipendent-particle and many-body approach, we show that the effect of local fields is crucial for describing properly the optical behavior of the crystalline case while it is of minor importance for amorphous systems.

description: Quantum control of individual spins in condensed matter systems is an emerging field with wide-ranging applications in spintronics, quantum computation, and sensitive magnetometry. Recent experiments have demonstrated the ability to address and manipulate single electron spins through either optical or electrical techniques. However, it is a challenge to extend individual spin control to nanoscale multi-electron systems, as individual spins are often irresolvable with existing methods. Here we demonstrate that coherent individual spin control can be achieved with few-nm resolution for proximal electron spins by performing single-spin magnetic resonance imaging (MRI), which is realized via a scanning magnetic field gradient that is both strong enough to achieve nanometric spatial resolution and sufficiently stable for coherent spin manipulations. We apply this scanning field-gradient MRI technique to electronic spins in nitrogen-vacancy (NV) centers in diamond and achieve nanometric resolution in imaging, characterization, and manipulation of individual spins. For NV centers, our results in individual spin control demonstrate an improvement of nearly two orders of magnitude in spatial resolution compared to conventional optical diffraction-limited techniques. This scanning-field-gradient microscope enables a wide range of applications including materials characterization, spin entanglement, and nanoscale magnetometry.

description: Macroscopic quantum phenomena (MQP) is a relatively new research venue, with exciting ongoing experiments and bright prospects, yet with surprisingly little theoretical activity. What makes MQP intellectually stimulating is because it is counterpoised against the traditional view that macroscopic means classical. In this series of papers we report on a systematic investigation into some key foundational issues of MQP, with the hope of constructing a viable theoretical framework for this new endeavour. The three major themes discussed in these three essays are the large N expansion, the correlation hierarchy and quantum entanglement for systems of `large' sizes, with many components or degrees of freedom. In this paper we use different theories in a variety of contexts to examine the conditions or criteria whereby a macroscopic quantum system may take on classical attributes, and, more interestingly, that it keeps some of its quantum features. The theories we consider here are, the O(N) quantum mechanical model, semiclassical stochastic gravity and gauge / string theories; the contexts include that of a `quantum roll' in inflationary cosmology, entropy generation in quantum Vlasov equation for plasmas, the leading order and next-to-leading order large N behaviour, and hydrodynamic / thermodynamic limits. By examining different representative systems where detailed theoretical analysis has been carried out, we find that there is no a priori good reason why quantum phenomena in macroscopic objects cannot exist.

description: We study the stellar response in a spectrum of potentials describing the barred spiral galaxy NGC 1300. These potentials have been presented in a previous paper and correspond to three different assumptions as regards the geometry of the galaxy. For each potential we consider a wide range of $Ω_p$ pattern speed values. Our goal is to discover the geometries and the $Ω_p$ supporting specific morphological features of NGC 1300. For this purpose we use the method of response models. In order to compare the images of NGC 1300 with the density maps of our models, we define a new index which is a generalization of the Hausdorff distance. This index helps us to find out quantitatively which cases reproduce specific features of NGC 1300 in an objective way. Furthermore, we construct alternative models following a Schwarzschild type technique. By this method we vary the weights of the various energy levels, and thus the orbital contribution of each energy, in order to minimize the differences between the response density and that deduced from the surface density of the galaxy, under certain assumptions. We find that the models corresponding to $Ω_p\approx16$\ksk and $Ω_p\approx22$\ksk are able to reproduce efficiently certain morphological features of NGC 1300, with each one having its advantages and drawbacks.

description: The creation of multilayer graphene (Gr), while preserving the brilliant properties of monolayer Gr derived from its unique band structure, can expand the application field of Gr to the macroscale. However, the energy-favorable AB stacking structure in the multilayer Gr induces a strong interlayer interaction and alters the band structure. Consequently, the intrinsic properties of each monolayer are degraded. In this work, we insert carbon nanotubes (CNTs) as nanospacers to modulate the microstructure of multilayer stacking Gr. Nanospacers can increase the interlayer distance and reduce the interlayer interaction. The Gr/CNT stacking structure is experimentally fabricated using a dry transfer method in a layer-by-layer manner. Raman spectroscopy verifies the reduction in the interlayer interaction within the stacking structure. Atomic force microscopy shows an increase in the interlayer distance, which can explain the weakening of the interlayer interactions. The microstructure of the stacked Gr and CNTs is studied by molecular dynamics simulation to systematically investigate the effect of CNT insertion. We found that the distribution distance, size, and arrangement of the CNT can modulate the interlayer distance. These results will help us to understand and improve the properties of the composite systems consisting of Gr and CNTs.

description: After irradiation, double stranded DNA leaked into the cytoplasm activates the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway, leading to the production of type I interferon (IFNI). In this study, we sought to probe the effect of ionizing radiation on activity of cGAS-STING-IFNI pathway in normoxic or hypoxic glioma cells and explore a more effective method to activate the signaling pathway, thereby activating the anti-tumor immune response and improving the therapeutic effect of radiotherapy for glioma. Human glioma cells U251 and T98G cultured in normoxia or hypoxia (1% O2) were irradiated with different doses of X ray. The relative expressions of cGAS, IFN-I stimulated genes (ISGs) and three-prime repair exonuclease 1 (TREX1) were detected by qPCR. The expression levels of interferon regulatory factor 3 (IRF3) and p-IRF3 proteins were detected by Western blot. The production of cGAMP and IFN-β in the supernatant was detected by ELISA assay. U251 and T98G cell lines with stable knockdown of TREX1 were established after transfection with lentivirus vectors. EdU cell proliferation assay was used to screen suitable metal ions concentrations. The phagocytosis of DCs was observed by immunofluorescence microscope. The phenotype of DCs was detected by flow cytometry. The migration ability of DCs was detected by transwell experiment. We found that cytosolic dsDNA, 2`3`-cGAMP, cGAS and ISGs expression, and IFN-β in cell supernatant were all increased with the doses of X-ray in the range of 0-16 Gy in normoxic glioma cells. Nevertheless, hypoxia significantly inhibited the radiation-induced dose-dependent activation of cGAS-STING-IFNI pathway. Furthermore, manganese (II) ion (Mn2+) significantly improved cGAS-STING-IFNI pathway activation induced by X-ray in both normoxic and hypoxic glioma cells, thereby promoting the maturation and migration of DCs. The responses of cGAS-STING-IFNI pathway to ionizing radiation were mainly investigated under normoxic condition, but the experiments described here indicated that hypoxia could hinder the pathway activation. However, Mn2+ showed radiosensitizing effects on the pathway under either normoxic or hypoxic condition demonstrating its potential as a radiosensitizer for glioma through activating anti-tumor immune response.

description: We discuss the finite-temperature phase diagram in the three-dimensional Bose-Hubbard (BH) model in the strong correlation regime, relevant for Bose-Einstein condensates in optical lattices, by employing a quantum rotor approach. In systems with strong on site repulsive interactions, the rotor U(1) phase variable dual to the local boson density emerges as an important collective field. After establishing the connection between the rotor construction and the the on--site interaction in the BH model the robust effective action formalism is developed which allows us to study the superfluid phase transition in various temperature--interaction regimes.

description: We use techniques from soft-collinear effective theory (SCET) to derive renormalization-group improved predictions for single-particle inclusive (1PI) observables in top-quark pair production at hadron colliders. In particular, we study the top-quark transverse-momentum and rapidity distributions, the forward-backward asymmetry at the Tevatron, and the total cross section at NLO+NNLL order in resummed perturbation theory and at approximate NNLO in fixed order. We also perform a detailed analysis of power corrections to the leading terms in the threshold expansion of the partonic hard-scattering kernels. We conclude that, although the threshold expansion in 1PI kinematics is susceptible to numerically significant power corrections, its predictions for the total cross section are in good agreement with those obtained by integrating the top-pair invariant-mass distribution in pair invariant-mass kinematics, as long as a certain set of subleading terms appearing naturally within the SCET formalism is included.

description: Problem statement: Clustering has a number of techniques that have been developed in statistics, pattern recognition, data mining, and other fields. Subspace clustering enumerates clusters of objects in all subspaces of a dataset. It tends to produce many over lapping clusters. Approach: Subspace clustering and projected clustering are research areas for clustering in high dimensional spaces. In this research we experiment three clustering oriented algorithms, PROCLUS, P3C and STATPC. Results: In general, PROCLUS performs better in terms of time of calculation and produced the least number of un-clustered data while STATPC outperforms PROCLUS and P3C in the accuracy of both cluster points and relevant attributes found. Conclusions/Recommendations: In this study, we analyze in detail the properties of different data clustering method.

Dynamic distribution of ryanodine receptors in cardiac muscles
Creators: name: Asghari, Parisa
Publisher: name: University of British Columbia
Year: 2014

description: The focus of this thesis is to address the location and distribution of the type 2 Ryanodine Receptor (RyR2) in mammalian cardiac myocytes with respect to their function. These integral membrane proteins function as Ca²⁺-activated Ca²⁺ ion channels as well as a scaffold for a large number of signaling molecules that modulate the release of Ca²⁺ through the channel. The relative position of the RyR2 tetramers is therefore a critical determinant of their function. To study this question, I have used a combination of immunofluorescence microscopy, transmission electron microscopy, and tomography to map the position of the tetramers in whole cells and in cell sections and have used tissue obtained from both rat and human hearts. Biochemical and physiological techniques were used to correlate structure with function. I have found that RyR2s are located only in three regions: in couplons on the surface, transverse tubules and on most of the axial tubules. In all regions, most but not all of the RyR2s colocalize with the voltage-gated Ca²⁺ channel (Cav1.2), suggesting that they play a role in excitation-contraction coupling. Some RyR2 are colocalized with cavelin-3 and not with Cav1.2 and hypothesized that these ‘extra-couplonic’ RyR2 might be regulated by the multitude of signaling molecules associated with caveolin-3 to modulate Ca²⁺ release. Dual-tilt electron tomography produced en face views of both rat and human dyads, enabling a direct examination of RyR2 arrangement. Both species showed that tetramer packing was non-uniform containing a mix of checkerboard and side-by-side arrangements as well as isolated tetramers. Finally, I showed that the tetramers’ arrangement depended on the Mg²⁺ concentration and on their phosphorylation status; in low Mg²⁺ and after phosphorylation RyR2s were positioned in largely checkerboard arrangements while in response to high Mg²⁺ the tetramers were positioned largely side by side. These tetramer arrangements: side by side, mixed and checkerboard were associated with progressively increasing spark frequencies. The correlation between tetramer arrangement and spark frequency suggests that tetramer rearrangement may be another mechanism whereby physiological processes operate and provides potential new mechanisms by which the activity of RYR2, the dyad and cardiac contractility may be regulated.

Applied drama as engaging pedagogy : critical multimodal literacies with street youth
Creators: name: Wager, Amanda Claudia
Publisher: name: University of British Columbia
Year: 2014

description: This critical ethnography investigates the pedagogical spaces constituted within a youth-led, participatory theatre production, Surviving in the Cracks (Wager et al., 2009). The popular theatre production documented the lived experiences of eight street-youth, including their struggles to survive in the face of cuts to public health resources in Vancouver. As an applied theatre study, this theatre project is defined as a messy and rich site of pedagogical inquiry that is examined through multiple theoretical and methodological frameworks. It draws on critical feminist pedagogy, critical youth studies and theatre and literacy research with the purpose of revealing how drama and theatre spaces provide “anomalous” (Ellsworth, 2005) learning places, or out-of-the-ordinary learning spaces, that youth and researchers collectively embodied during the applied drama and theatre process and production. Analysis of ethnographic data generated before, during, and after the theatrical production of Surviving in the Cracks suggests how drama and theatre with street youth opens up embodied pedagogical spaces. Two different methods of analysis bring multiple perspectives to this work through exploring how meaning was collectively constructed, how multimodal literacy practices were used in critical ways, how power was negotiated, how desire was manifested through imaginaries, and how safe spaces were generated by this community of youth within selected pedagogical moments of resistance during the theatre process. Specifically, the script is analyzed with a youth participant, followed by the analysis of particular moments of resistance during performance creation and production. This research advances knowledge of how informal learning spaces and youth resistances within education become crucial parts of pedagogy and should be considered as future foundations and expansions of education. Implications include using multiple methodological lenses in order to work alongside, for and with youth, as well as being able to reach larger audiences of youth, communities, educators, and scholars through different analytical perspectives. By examining how theatre provides a space for marginalized youth to engage in dialogues about complex social issues, this research contributes to the fields of critical and feminist pedagogy, language and literacy education, drama in education, critical youth studies, and collaborative methodological studies in qualitative research.

description: Despite recent advances in uncovering the quantitative features of stationary human activity patterns, many applications, from pandemic prediction to emergency response, require an understanding of how these patterns change when the population encounters unfamiliar conditions. To explore societal response to external perturbations we identified real-time changes in communication and mobility patterns in the vicinity of eight emergencies, such as bomb attacks and earthquakes, comparing these with eight non-emergencies, like concerts and sporting events. We find that communication spikes accompanying emergencies are both spatially and temporally localized, but information about emergencies spreads globally, resulting in communication avalanches that engage in a significant manner the social network of eyewitnesses. These results offer a quantitative view of behavioral changes in human activity under extreme conditions, with potential long-term impact on emergency detection and response.
Random matrix model for QCD_3 staggered fermions

description: We show that the lowest part of the eigenvalue density of the staggered fermion operator in lattice QCD_3 at small lattice coupling constant beta has exactly the same shape as in QCD_4. This observation is quite surprising, since universal properties of the QCD_3 Dirac operator are expected to be described by a non-chiral matrix model. We show that this effect is related to the specific nature of the staggered fermion discretization and that the eigenvalue density evolves towards the non-chiral random matrix prediction when beta is increased and the continuum limit is approached. We propose a two-matrix model with one free parameter which interpolates between the two limits and very well mimics the pattern of evolution with beta of the eigenvalue density of the staggered fermion operator in QCD_3.

description: The motion of a gas-liquid interface along a solid wall is influenced by the capillary forces resulting from the interface's shape and its interaction with the solid, where it forms a dynamic contact angle. Capillary models play a significant role in the management of cryogenic propellants in space, where surface tension dominates the behaviour of gas-liquid interfaces. Yet, most empirical models have been derived in configurations dominated by viscous forces. In this study, we experimentally investigate the wetting of a low-viscosity, highly wetting fluid in a reduced gravity environment. Our setup consisted of a transparent and diverging U-tube in which capillary forces sustain the liquid motion. Combining Particle Image Velocimetry (PIV) and high-speed backlighting visualization, the experimental campaign allowed for measuring the interface evolution and the velocity field within the liquid under varying gravity levels. This work reports on the preliminary results from the image velocimetry and shows that the velocity profile within the tube is close to parabolic until a short distance from the interface. Nevertheless, classic 1D models for capillary rise face difficulties reproducing the interface dynamics, suggesting that the treatment of the surface tension in these problems must be reviewed.

description: The Wigner-Weisskopf-type model describing the energy transfer between two centers mediated by a continuum of energy levels is studied. This work is motivated by the recent interest in transport phenomena at nanoscale in biology and quantum engineering. The analytical estimation for the energy transfer efficiency is derived in the weak coupling regime and the conditions for the almost perfect transfer are discussed. The embedding of the standard tight-binding model into Wigner-Weisskopf one which includes the environmental noise is presented.

description: Probabilistic broadcast has been widely used as a flooding optimization mechanism to alleviate the effect of broadcast storm problem (BSP) in mobile ad hoc networks (MANETs). Many research studies have been carried-out to develop and evaluate the performance of this mechanism in an error-free (noiseless) environment. In reality, wireless communication channels in MANETs are an error-prone and suffer from high packet-loss due to presence of noise, i.e., noisy environment. In this paper, we propose a simulation model that can be used to evaluate the performance of probabilistic broadcast for flooding in noisy environment. In the proposed model, the noise-level is represented by a generic name, probability of reception (pc) (0<=pc<=1), where pc=1 for noiseless and <1 for noisy environment. The effect of noise is determined randomly by generating a random number ζ(0<=ζ<1); if ζ<=pc means the packet is successfully delivered to the receiving node, otherwise, unsuccessful delivery occurs. The proposed model is implemented on a MANET simulator, namely, MANSim. The effect of noise on the performance of probabilistic algorithm was investigated in four scenarios. The main conclusions of these scenarios are: the performance of probabilistic algorithm suffers in presence of noise. However, this suffering is less in high density networks, or if the nodes characterized by high retransmission probability or large radio transmission range. The nodes' speed has no or insignificant effect on the performance.

description: Both regular (the zero-momentum ghost dressing function not diverging), also named decoupling, and critical (diverging), also named scaling, Yang-Mills propagators solutions can be obtained by analyzing the low-momentum behaviour of the ghost propagator Dyson-Schwinger equation (DSE) in Landau gauge. The asymptotic expression obtained for the regular or decoupling ghost dressing function up to the order ${\cal O}(q^2)$ fits pretty well the low-momentum ghost propagator obtained through the numerical integration of the coupled gluon and ghost DSE in the PT-BFM scheme. Furthermore, when the size of the coupling renormalized at some scale approaches some critical value, the PT-BFM results seems to tend to the the scaling solution as a limiting case.

description: Structure functions are a measure of the partonic structure of hadrons, which is important for any process which involves colliding hadrons. They are a key ingredient for deriving partons distributions in nucleons. In recent years dramatic progress has been made in the understanding of the nucleon structure and the precision of its partonic content, due to vast theoretical progress, and the availability of new high precision measurements. This review gives an overview on present structure function and related data, and on the most recent techniques used to extract parton distribution functions to describe the structure of the proton. Special attention is given to the determination of the uncertainties on the parton distributions.
