description: Complex oxide interfaces have been one of the central focuses in condensed matter physics and material science. Over the past decade, aberration corrected scanning transmission electron microscopy and spectroscopy has proven to be invaluable to visualize and understand the emerging quantum phenomena at an interface. In this paper, we briefly review some recent progress in the utilization of electron microscopy to probe interfaces. Specifically, we discuss several important challenges for electron microscopy to advance our understanding on interface phenomena, from the perspective of variable temperature, magnetism, electron energy loss spectroscopy analysis, electronic symmetry, and defects probing.

On the nonlinear behaviour of population dynamics in electric demand forecasting
Creators: name: Hook, Chris
Publisher: name: University of British Columbia
Year: 2010

description: The problem of electric demand forecasting is analyzed for behavioral traits in the hope that an underlying dynamical process may be revealed. It is assumed that since electric demand is closely related to population growth, the iterative chaotic quadratic difference equation should yield a deeper level of insight toward the understanding of such a process. In particular, the topic of mathematical dynamical systems is developed and then applied, first to problems of constrained population growth, and then to the pertinent issue of per capita electric power demand. A new, randomized quadratic difference model is developed whose behavior appears both predictable and unexpected. Of primary significance, it was found that the hypothesized underlying dynamical system was sensitive to both the level or rate of population growth and the mean level of a randomly distributed (where a gaussian distribution was assumed) per capita electric demand. This was concluded with suggestions on relevant analytical models to be used for forecasting under differing parametric situations.

description: Metallographic examination of improved structures of Avinit С multilayer nitride-based coatings, particularly coatings of Ti-Al-N system and Mo-N system-based coating have been carried out. Use of effective methods of surface cleaning and three-level arc control system in the techniques under development for prevention of surface damaging, caused by micro arcs, allows to apply coatings of precision and high finish class surfaces up to 12 – 13 grade of finish without deterioration of surface finish class. The experimental findings confirm a possibility of low-temperature deposition of very hard Avinit С coatings based on nitrides of metals under the conditions providing good adhesion to the parent material (steel DIN 1.2379 (Х12Ф1) without decrease in strength properties of the steel (<200 °C) and without distortion of the coated surfaces. Tribological examination of advanced constructions of multicomponent multilayer Avinit coatings under aviation fuel ТS-1 for the purpose of selection of coating materials for friction parts of precision couples used in aggregate building. Deposition of coatings effectively raises durability of friction pairs to scoring. Advanced coatings have low friction coefficients (0.75 − 0.095) at loadings up to 2.0 kN and have shown high wear resistance. The received results allow to develop software products for obtaining of multicomponent multilayer coatings of required composition using Avinit equipment and tryout stable techniques for deposition of functional coatings to be used in friction parts of precision couples of standard aircraft units. Keywords: Plasma-vacuum deposited multicomponent multilayer, nanolayer coatings; tribology.

description: The fundamental understanding of crystallization, in terms of microscopic kinetic and thermodynamic details, remains a key challenge in the physical sciences. Here, by using in situ graphene liquid cell transmission electron microscopy, we reveal the atomistic mechanism of NaCl crystallization from solutions confined within graphene cells. We find that rock salt NaCl forms with a peculiar hexagonal morphology. We also see the emergence of a transitory graphite-like phase, which may act as an intermediate in a two-step pathway. With the aid of density functional theory calculations, we propose that these observations result from a delicate balance between the substrate-solute interaction and thermodynamics under confinement. Our results highlight the impact of confinement on both the kinetics and thermodynamics of crystallization, offering new insights into heterogeneous crystallization theory and a potential avenue for materials design.

Competence as "good management practice" : a study of curriculum reform in the community college
Creators: name: Jackson, Nancy S.
Publisher: name: University of British Columbia
Year: 2010

description: In the last decade, the concept of competence has become a powerful ideological force as a component of public policy in the post-compulsory sector of vocational/technical education in Canada. It has served as a device for articulating vocational policy and practice to the changing conditions for capital accumulation in the context of economic and social restructuring. This process of articulation is most readily visible at the level of broad public policy statements and political rhetoric calling for reform of the relation between education and work. Less clear is how competency measures give practical expression to these broad policy objectives at the level of routine curricular and institutional arrangements. These issues form the central empirical focus of the thesis, through an investigation of the work process of teachers and administrators involved in implementing competency measures in the college setting. The central argument is that competency measures effect a fundamental transformation in the organization of curriculum decision making in the college setting. They accomplish the suppression of broad, long-term educational goals in favour of narrow, short-term ones, as a means to increase "flexibility" in labour supply. They limit the use of educational theory as the basis of curriculum decisions and replace it with a set of ideological procedures for constituting "needs" and "requirements" related to job performance. These changes are brought about in part through the imposition of formal, documentary information systems to replace the discretionary judgment and interpretive practices of instructors, making the instructional process accountable within a centrally determined policy process. Through this re-organization of educational decision-making, learning is displaced by managing as the form of praxis which gives shape to curricular organization. The form of competence that is brought into being is not a feature of the performance ability of individuals but an aspect of "good management practice" in educational settings.
Noise driven current reversal and stabilisation in the tilted ratchet potential subject to tempered stable Lévy noise

description: We consider motion of a particle in a one-dimensional tilted ratchet potential subject to two-sided tempered stable Lévy noise characterised by strength $Ω$, fractional index $α$, skew $θ$ and tempering $λ$. We derive analytic solutions to the corresponding Fokker-Planck Lévy equations for the probability density. Due to the periodicity of the potential, we carry out reduction to a compact domain and solve for the analogue there of steady-state solutions which we represent as wrapped probability density functions. By solving for the expected value of the current associated with the particle motion, we are able to determine threshold for metastability of the system, namely when the particle stabilises in a well of the potential and when the particle is in motion, for example as a consequence of the tilt of the potential. Because the noise may be asymmetric, we examine the relationship between skew of the noise and the tilt of the potential. With tempering, we find two remarkable regimes where the current may be reversed in a direction opposite to the tilt or where the particle may be stabilised in a well in circumstances where deterministically it should flow with the tilt.

Manipulator inverse kinematics based on recursive least squares estimation
Creators: name: Hutchinson, Derek Charles Glenn
Publisher: name: University of British Columbia
Year: 2010

description: The inverse kinematics problem for six degree of freedom robots having a separable structure with the wrist equivalent to a spherical joint is considered and an iterative solution based on estimating the inverse Jacobian by recursive least squares estimation is proposed. This solution is found to have properties similar to Wampler's Damped Least Squares method and provides a stable result when the manipulator is in singular regions. Furthermore, the solution is more computationally efficient than Wampler's method; however, its best performance is obtained when the distances between the current end effector pose and the target pose are small. No knowledge of the manipulator's geometry is required provided that the end effector and joint position data are obtained from sensor information. This permits the algorithm to be readily transferable among manipulators and circumvents detailed analysis of the manipulator's structure.

Flux erosion of magnetic clouds by reconnection with the Sun's open flux

description: Magnetic clouds (MCs) are flux-rope magnetic structures forming a subset of solar coronal mass ejections which have significant space weather impacts. The geoeffectiveness of MCs depends on their properties which evolve during their interplanetary passage. Based on an analysis of observations spanning two solar cycles we establish that MCs interacting with the ambient solar wind magnetic field (i.e., heliospheric open flux) lose a substantial amount of their initial magnetic flux via magnetic reconnection, which in some cases, reduce their geoeffectiveness. We find a linear correlation between the eroded flux of MCs and solar open flux which is consistent with the scenario that MC erosion is mediated via the local heliospheric magnetic field draping around an MC during its interplanetary propagation. The solar open flux is governed by the sunspot cycle. This work therefore uncovers a hitherto unknown pathway for solar cycle modulation of the properties of MCs.

In the beginning of 2020, the coronavirus disease 2019 (COVID-19) has caused a pandemic disease in over 200 countries, affecting billions of humans. Identifying and separating the infected people during the early stage is the most important step in controlling
the pandemic. However, the main diagnostic tool, i.e., RT-PCR test, does not have high sensitivity for diagnosing COVID-19.  However, chest CT is a valuable complementary tool in the early stage that offers high sensitivity. But chest CT test requires 21.5 minutes even for experienced radiologists that were severely lacking in the pandemic. Designing an automatic diagnosis system is highly desirable in solving this issue.

Based on the above motivation, we developed a novel Joint Classification and Segmentation (JCS) system to perform a real-time and explainable COVID-19 chest CT diagnosis. To enable the training of our system, we collected a large-scale COVID-19 classification and segmentation (COVID-CS) dataset, with 144K chest CT images of 400 COVID-19 patients and 350 uninfected cases. We annotated 3,855 chest CT images of 200 patients with fine-grained pixel-level labels of opacifications, which are increased attenuation of the lung parenchyma. We also have annotated lesion counts, opacification areas, and locations that benefit various diagnosis aspects. Extensive experiments demonstrate that the proposed JCS diagnosis system is very efficient for COVID-19 classification and segmentation. It obtains an average sensitivity of 95.0% and a specificity of 93.0% on the classification test set, and 78.5% Dice score on the segmentation test set of our COVID-CS dataset. The COVID-CS dataset and code are available at https://github.com/yuhuan-wu/JCS.

description: Coverage control has been widely used for constructing mobile sensor network such as for environmental monitoring, and one of the most commonly used methods is the Lloyd algorithm based on Voronoi partitions. However, when this method is used, the result sometimes converges to a local optimum. To overcome this problem, game theoretic coverage control has been proposed and found to be capable of stochastically deriving the optimal deployment. From a practical point of view, however, it is necessary to make the result converge to the global optimum deterministically. In this paper, we propose a global optimal coverage control along with collision avoidance in continuous space that ensures multiple sensors can deterministically and smoothly move to the global optimal deployment. This approach consists of a cut-in algorithm based on neighborhood importance of measurement and a modified potential method for collision avoidance. The effectiveness of the proposed algorithm has been confirmed through numerous simulations and some experiments using multiple aerial robots.

description: In this work, we have studied the crystal defectiveness and doping activation subsequent to ion implantation and post-annealing by using various techniques including photoluminescence (PL), Raman spectroscopy and transmission electron microscopy (TEM). The aim of this work was to test the effectiveness of double step annealing to reduce the density of point defects generated during the annealing of a P implanted 4H-SiC epitaxial layer. The outcome of this work evidences that neither the first, 1 hour isochronal annealing at 1650 - 1700 - 1750 °C, nor the second one, at 1500 °C for times between 4 hour and 14 hour, were able to recover a satisfactory crystallinity of the sample and achieve dopant activations exceeding 1%.
Speech recognition in a harsh environment
Creators: name: Pullman, Susan
Publisher: name: University of British Columbia
Year: 2010

description: Speech Recognition is a rapidly expanding field with many useful applications in man-machine interfacing. One of the main benefits of speech control is the flexibility and ease of use allowed an operator for any number of specific applications. Speech recognition units (SRU) are currently at a high level of accuracy for user dependent, pretrained, isolated word recognition. However, if uncontrollable noise is added to the speech input, recognition degrades rapidly. If the application requires a vast set of control words to be used by many operators, then, there can be inconsistencies in recognition. The specific application of this study is the secondary control (ie. non-critical control) of heavy machinery (in particular a caterpillar tractor) using an operator - speech interface. The inherent problem of this application is the environmental background noise due to the tractor. It is also important that a robust vocabulary is selected so that no misrecognition occurs between critical control words. In order to add speech input for control of machines in a harsh environment there are two considerations: 1. The reduction of noise from the input speech signal. 2. The selection of a robust vocabulary dependent upon the specific operator and the specific SRU. This study investigates many different types of noise reduction filters, including traditional Wiener, Power Spectral Subtraction and Gaussian filters. The results show that the best types of noise reduction filters are adaptive optimization filters which use two input signals or the Power Spectral Subtraction (PSS) filter. It is possible to reduce the noise to a level within the range of the SRU's capacity for noise. An algorithm for selecting an accurate vocabulary is proposed. This algorithm determines weaknesses for the specific SRU, vocabulary and speaker; and selects the control words around those weaknesses. Testing of this algorithm showed that it was possible to achieve closed to 98% recognition and 0% misrecognition.

description: In this paper, we first define the complexification of a real analytic map between real analytic Koszul manifolds and show that the complexified map is the holomorphic extension of the original map. Next we define an anti-Kaehler metric compatible with the adapted complex structure on the complexification of a real analytic pseudo-Riemannian manifold. In particular, for a pseudo-Riemannian homogeneous space, we define another complexification and a (complete) anti-Kaehler metric on the complexification. One of main purposes of this paper is to find the interesting relation between these two complexifications (equipped with the anti-Kaehler metrics) of a pseudo-Riemannian homogeneous space. Another of main purposes of this paper is to show that almost all principal orbits of some isometric action on the first complexification (equipped with the anti-Kaehler metric) of a semi-simple pseudo-Riemannian symmetric space are curvature-adapted isoparametric submanifolds with flat section in the sense of this paper.

description: We develop a theory of entanglement distillation that exploits a convolutional coding structure. We provide a method for converting an arbitrary classical binary or quaternary convolutional code into a convolutional entanglement distillation protocol. The imported classical convolutional code does not have to be dual-containing or self-orthogonal. The yield and error-correcting properties of such a protocol depend respectively on the rate and error-correcting properties of the imported classical convolutional code. A convolutional entanglement distillation protocol has several other benefits. Two parties sharing noisy ebits can distill noiseless ebits ``online'' as they acquire more noisy ebits. Distillation yield is high and decoding complexity is simple for a convolutional entanglement distillation protocol. Our theory of convolutional entanglement distillation reduces the problem of finding a good convolutional entanglement distillation protocol to the well-established problem of finding a good classical convolutional code.

A priority scheme composed of 1-persistent and non-persistent CSMA protocols is proposed. The throughput and delay characteristics of this protocol are evaluated by mathematical analysis and simulation, respectively. The approach of throughput analysis is further extended to another more general case, p-persistent CSMA with two persistency factors, the throughput performance of which had not been analyzed before. Simulations are carried out to study the delay characteristics of this protocol. After careful consideration of the features of the priority schemes studied, two protocols are proposed for integrated voice and data transmission. While their ultimate purpose is for integrated services, they have different application. One of them is applied to local area network; the other is suitable for packet radio network. The distinctive features of the former are simplicity and flexibility. The latter is different from other studies in that collision detection is not required, and that it has small mean and variance of voice packet delay. Performance characteristics of both of these protocols are examined by simulations under various system parameter values.

description: Low magnetic field scanning tunneling spectroscopy of individual Abrikosov vortices in heavily overdoped Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ unveils a clear d-wave electronic structure of the vortex core, with a zero-bias conductance peak at the vortex center that splits with increasing distance from the core. We show that previously reported unconventional electronic structures, including the low energy checkerboard charge order in the vortex halo and the absence of a zero-bias conductance peak at the vortex center, are direct consequences of short inter-vortex distance and consequent vortex-vortex interactions prevailing in earlier experiments.

description: Could John Kerry have gained votes in the 2004 Presidential election by more clearly distinguishing himself from George Bush on economic policy? At first thought, the logic of political preferences would suggest not: the Republicans are to the right of most Americans on economic policy, and so in a one-dimensional space with party positions measured with no error, the optimal strategy for the Democrats would be to stand infinitesimally to the left of the Republicans. The median voter theorem suggests that each party should keep its policy positions just barely distinguishable from the opposition. In a multidimensional setting, however, or when voters vary in their perceptions of the parties' positions, a party can benefit from putting some daylight between itself and the other party on an issue where it has a public-opinion advantage (such as economic policy for the Democrats). We set up a plausible theoretical model in which the Democrats could achieve a net gain in votes by moving to the left on economic policy, given the parties' positions on a range of issue dimensions. We then evaluate this model based on survey data on voters' perceptions of their own positions and those of the candidates in 2004. Under our model, it turns out to be optimal for the Democrats to move slightly to the right but staying clearly to the left of the Republicans' current position on economic issues.

description: We investigate the structure of conformal Regge trajectories for the maximally supersymmetric (2,0) theories in six dimensions. The different conformal multiplets in a single superconformal multiplet must all have similarly-shaped Regge trajectories. We show that these super-descendant trajectories interact in interesting ways, leading to new constraints on their shape. For the four-point function of the stress tensor multiplet supersymmetry also softens the Regge behavior in some channels, and consequently we observe that 'analyticity in spin' holds for all spins greater than -3. All the physical operators in this correlator therefore lie on Regge trajectories and we describe an iterative scheme where the Lorentzian inversion formula can be used to bootstrap the four-point function. Some numerical experiments yield promising results, with OPE data approaching the numerical bootstrap results for all theories with rank greater than one.

description: Electron correlation is crucial for the description of a wide range of phenomena in physics, chemistry and biology. Due to their delocalisation and ease of extrapolation to the basis-set limit, plane waves would be ideally suited for the calculation of basis-set limit correlation energies. Alas, the routine use of correlated wavefunction approaches in a plane-wave basis is hampered by a prohibitive scaling due to a number of virtual continuum states which quickly reaches the tens of thousands. However, it is also the presence of these very states that has been shown to substantially facilitate extrapolation to the basis-set limit [1]. Among correlated wavefunction methods, second-order Møller-Plesset perturbation theory (MP2) is one of the most expedient approaches and exhibits a comparably flat formal scaling of O(N^5). Still, so far, MP2 calculations in plane waves have not been feasible for all but the smallest systems. We present a method that is able to overcome the current limitations of MP2 theory in plane waves by introducing a stochastic sampling based on Monte-Carlo summation over continuum orbitals, which allows for speedups of up to a factor of 1000. Given a fixed number of sampling points, the resulting algorithm is dominated by a flat scaling of ∼O(N^2). The resulting, absolute correlation energies are accurate to <0.1 kcal/mol or <0.1 meV/electron, respectively. Overall, the method outlined here allows for the calculation of basis-set limit correlation energies with unprecedented gains of efficiency and allow for the treatment of large systems intractable so far. Plane-wave basis-set limit values for correlation energies therefore become within reach for periodic or isolated systems containing several hundreds of electrons. [1] Shepherd, J.

description: The joint cumulative distribution function for order statistics arising from several different populations is given in terms of the distribution function of the populations. The computational cost of the formula in the case of two populations is still exponential in the worst case, but it is a dramatic improvement compared to the general formula by Bapat and Beg. In the case when only the joint distribution function of a subset of the order statistics of fixed size is needed, the complexity is polynomial, for the case of two populations.

description: We consider the modification of the Cahn-Hilliard equation when a time delay process through a memory function is taken into account. We then study the process of spinodal decomposition in fast phase transitions associated with a conserved order parameter. The introduced memory effect plays an important role to obtain a finite group velocity. Then, we discuss the constraint for the parameters to satisfy causality. The memory effect is seen to affect the dynamics of phase transition at short times and has the effect of delaying, in a significant way, the process of rapid growth of the order parameter that follows a quench into the spinodal region.

description: Superfield methods can be used to determine the precise way the self-dual five-form couples to the metric in the first non-trivial $α'$ corrections to type IIB supergravity. We explicitly compute the exact tensor structure of these terms. This requires extensive use of computing algorithms to reduce the complicated expressions that appear to a surprisingly simple form. Along the way we show a new method of computing Schouten identities. With this result we clarify under which conditions one may neglect the five-form higher derivative terms. We comment on corrections to the thermodynamics of charged black holes.

description: In previous work we showed that a semi-empirical model in which galaxies in host dark matter haloes are assigned stellar masses via a stellar mass-halo mass (SMHM) relation and sizes ($R_e$) via a linear and tight $R_e-R_h$ relation, can faithfully reproduce the size function of local SDSS central galaxies and the strong size evolution of massive galaxies (MGs, $M_{\rm star}>10^{11.2}M_\odot$). In this third paper of the series, we focus on the population of satellite MGs. We find that without any additional calibration and irrespective of the exact SMHM relation, fraction of quenched galaxies or level of stellar stripping, the same model is able to reproduce the local size function of quiescent satellite MGs in SDSS. In addition, the same model can reproduce the puzzling weak dependence of mean size on host halo mass for both central and satellite galaxies. The model also matches the size function of starforming satellite MGs, after assuming that some of them transform into massive lenticulars in a few Gyr after infalling in the group/cluster environment. However, the vast majority of satellite lenticulars is predicted to form before infall. The $R_e-R_h$ appears to be fundamental to connect galaxies and their host haloes.

description: We investigate the results of recently published experiments on the quantum behavior of Josephson circuits in terms of the classical modelling based on the resistively and capacitively-shunted (RCSJ) junction model. Our analysis shows evidence for a close analogy between the nonlinear behavior of a pulsed microwave-driven Josephson junction at low temperature and low dissipation and the experimental observations reported for the Josephson circuits. Specifically, we demonstrate that Rabi-oscillations, Ramsey-fringes, and spin-echo observations are not phenomena with a unique quantum interpretation. In fact, they are natural consequences of transients to phase-locking in classical nonlinear dynamics and can be observed in a purely classical model of a Josephson junction when the experimental recipe for the application of microwaves is followed and the experimental detection scheme followed. We therefore conclude that classical nonlinear dynamics can contribute to the understanding of relevant experimental observations of Josephson response to various microwave perturbations at very low temperature and low dissipation.
