description: We establish a correspondence between Young diagrams and differential operators of infinitely many variables. These operators form a commutative associative algebra isomorphic to the algebra of the conjugated classes of finite permutations of the set of natural numbers. The Schur functions form a complete system of common eigenfunctions of these differential operators, and their eigenvalues are expressed through the characters of symmetric groups. The structure constants of the algebra are expressed through the Hurwitz numbers.

description: Digital twin has revolutionized optical communication networks by enabling their full life-cycle management, including design, troubleshooting, optimization, upgrade, and prediction. While extensive literature exists on frameworks, standards, and applications of digital twin, there is a pressing need in implementing digital twin in field-deployed optical networks operating in real-world environments, as opposed to controlled laboratory settings. This paper addresses this challenge by examining the uncertain factors behind the inaccuracy of digital twin in field-deployed optical networks from three main challenges and proposing operational guidance for implementing accurate digital twin in field-deployed optical networks. Through the proposed guidance, we demonstrate the effective implementation of digital twin in a field-trial C+L-band optical transmission link, showcasing its capabilities in performance recovery in a fiber cut scenario.

description: Quasi-Periodic Oscillations (QPOs) observed during Soft Gamma Repeaters giant flares are commonly interpreted as the torsional oscillations of magnetars. The oscillatory motion is influenced by the strong interaction between the shear modes of the crust and Alfven-like modes in the core. We study the dynamics which arises through this interaction, and present several new results: (1) We show that global {\it edge modes} frequently reside near the edges of the core Alfven continuum. (2) We compute the magnetar's oscillatory motion for realistic axisymmetric magnetic field configurations and core density profiles, but with a simplified model of the elastic crust. We show that one may generically get multiple gaps in the Alfven continuum. One obtains discrete global {\it gap modes} if the crustal frequencies belong to the gaps. (3) We show that field tangling in the core enhances the role of the core discrete Alfven modes and reduces the role of the core Alfven continuum in the overall oscillatory dynamics of the magnetar. (4) We demonstrate that the system displays transient and/or drifting QPOs when parts of the spectrum of the core Alfven modes contain discrete modes which are densely and regularly spaced in frequency. (5) We show that if the neutrons are coupled into the core Alfven motion, then the post-flare crustal motion is strongly damped and has a very weak amplitude. Thus magnetar QPOs give evidence that the proton and neutron components in the core are dynamically decoupled and that at least one of them is a quantum fluid. (6) We show that it is difficult to identify the high-frequency 625 Hz QPO as being due to the physical oscillatory mode of the magnetar, if the latter's fluid core consists of the standard proton-neutron-electron mixture and is magnetised to the same extent as the crust.

description: Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and Unmanned Aerial Vehicles (UAVs). The solution is to make use of so-called thermals, which are localized, warmer regions in the atmosphere moving upwards with a speed exceeding the descent rate of birds and planes. Saving energy by exploiting the environment more efficiently is an important possibility for autonomous UAVs as well. Successful control strategies have been developed recently for UAVs in simulations and in real applications. This paper first presents an overview of our knowledge of the soaring flight and strategy of birds, followed by a discussion of control strategies that have been developed for soaring UAVs both in simulations and applications on real platforms. To improve the accuracy of simulation of thermal exploitation strategies we propose a method to take into account the effect of turbulence. Finally we propose a new GPS independent control strategy for exploiting thermal updraft.

Regulation and transport of apolipoprotein A-I into the central nervous system and therapeutic potential in Alzheimer's disease
Creators: name: Stukas, Katrina Sophie Claire
Publisher: name: University of British Columbia
Year: 2014

description: Patients with Alzheimer’s Disease (AD) exhibit substantial cerebrovascular damage, including the accumulation of β-amyloid (Aβ) peptides within the vessel wall. Mid-life vascular risk factors increase the risk of AD potentially via the loss of beneficial or gain of toxic functions in circulating high density lipoprotein (HDL). Low plasma levels of apolipoprotein A-I (apoA-I), the primary protein component of HDL, increase AD risk and correlate with cognitive decline, and preliminary preclinical evidence supports a role of apoA-I in mediating removal of cerebrovascular Aβ, suppressing neuroinflammation, and enhancing cognitive function. Our strategy was to perturb peripheral and central nervous system (CNS) apoA-I levels through genetic modification of proteins known to regulate apoA-I metabolism and via indirect and direct pharmacological manipulation of apoA-I to delineate its CNS transport, regulation and therapeutic potential in AD. Loss of ATP binding cassette transporter A1 (ABCA1), which effluxes cholesterol onto lipid-poor apoA-I to generate immature pre-β-HDL, lead to significant parallel decreases of circulating and CNS apoA-I, while stimulation of ABCA1 activity with an Liver-X-Receptor (LXR) agonist substantially increased apoA-I levels selectively in the CNS, solubilized Aβ and improved cognitive function in AD mice. Although apoA-I was increased independent of ABCA1, ABCA1 was required to observe LXR-mediated cognitive benefits, suggesting lipidation of apolipoproteins is a critical regulator of their function. Pre-β-HDL appear to be the more biologically relevant species regarding CNS health, as loss of lecithin-cholesterol acetyl transferase (LCAT), which esterifies free cholesterol to generate mature α-HDL, does not impact AD pathology in vivo. Intravenously injected human apoA-I gains access to the CNS predominantly via the blood cerebrospinal fluid barrier, where it is bound, internalized, and transported by the epithelial cells of the choroid plexus in a specific receptor mediated fashion. Weekly injection of reconstituted HDL, formulated to enrich the pre-β pool, into symptomatic AD mice transiently decreased plasma Aβ levels but was unable to modulate brain Aβ, neuroinflammation, or endothelial activation in the experimental paradigm used. Collectively, these data identified ABCA1 generated apoA-I pre-β-HDL species as a key population of HDL subspecies for modulating AD pathology in vivo.
Brownian shape motion on five-dimensional potential-energy surfaces: Nuclear fission-fragment mass distributions

description: Although nuclear fission can be understood qualitatively as an evolution of the nuclear shape, a quantitative description has proven to be very elusive. In particular, until now, there exists no model with demonstrated predictive power for the fission fragment mass yields. Exploiting the expected strongly damped character of nuclear dynamics, we treat the nuclear shape evolution in analogy with Brownian motion and perform random walks on five-dimensional fission potential-energy surfaces which were calculated previously and are the most comprehensive available. Test applications give good reproduction of highly variable experimental mass yields. This novel general approach requires only a single new global parameter, namely the critical neck size at which the mass split is frozen in, and the results are remarkably insensitive to its specific value.

description: We discuss constraints from cosmology on the models with direct gauge mediation based on the ISS supersymmetry breaking models. It is a generic feature that the ISS models possess a U(1) symmetry which is eventually spontaneously broken, when the models are based on the gauge symmetries with complex representations. We show that the resultant pseudo Nambu-Goldstone boson causes problems in cosmology, which leads to severe constraints on the models. We also show that most parameter space of the models can be probed by observing gravitational waves emitted from the cosmic string network when the U(1) symmetry is a gauge symmetry.

description: The case study of a 32-atoms Si nanocrystallite (NC) embedded in a SiO2 matrix, both crystalline and amorphous, or free-standing with different conditions of passivation and strain is analyzed through ab-initio approaches. The Si32/SiO2 heterojunction shows a type I band offset highlighting a separation between the NC plus the interface and the matrix around. The consequence of this separation is the possibility to correctly reproduce the low energy electronic and optical properties of the composed system simply studying the suspended NC plus interface oxygens with the appropriate strain. Moreover, through the definition of an optical absorption threshold we found that, beside the quantum confinement trend, the amorphization introduces an additional redshift that increases with increasing NC size: i.e. the gap tends faster to the bulk limit. Finally, the important changes in the calculated DFT-RPA optical spectra upon inclusion of local fields point towards the need of a proper treatment of the optical response of the interface region.

description: A time-dependent potential barrier has been used to probe the arrival-time distribution of the wave packet of a hot electron by raising the barrier to block the packet upon arrival of the packet at the barrier. To see whether the barrier precisely detects the distribution, it is necessary to study an error caused by a finite rising speed of the barrier. For this purpose, we study transmission of an electron wave packet through the dynamical barrier, and identify two regimes, the semiclassical regime and the quasistatic regime. In each regime, we calculate the arrival-time distribution reconstructed by using the barrier and quantify the error in the detection, the difference of the temporal uncertainty between the wave-packet distribution and the reconstructed distribution. Our finding suggests that for precise detection, the time scale, in which the barrier height rises over the energy distribution of the wave packet and the tunneling energy window of the barrier, has to be much shorter than the temporal uncertainty of the wave packet. The analytical results are confirmed with numerical calculations.

description: Accurate fundamental parameters of stars are mandatory for the asteroseismic investigation of the Kepler mission to succeed. We will determine the atmospheric parameters for a sample of 6 well-studied bright K giants to confirm that our method produces reliable results. We then apply the same method to 14 K giants that are targets for the Kepler mission. We have used high-resolution, high signal-to-noise spectra from the FIES spectrograph on the Nordic Optical Telescope. We used the iterative spectral synthesis method VWA to derive the fundamental parameters from carefully selected high-quality iron lines and pressure-sensitive Calcium lines. We find good agreement with parameters from the literature for the 6 bright giants. We compared the spectroscopic values with parameters based on photometric indices in the Kepler Input Catalogue (KIC). We identify serious problems with the KIC values for [Fe/H] and find a large RMS scatter of 0.5 dex. The log g values in KIC agree reasonably well with the spectroscopic values with a scatter of 0.25 dex, when excluding two low-metallicity giants. The Teffs from VWA and KIC agree well with a scatter of about 85 K. We also find good agreement with log g and Teff derived from asteroseismic analyses for seven Kepler giant targets. We have determined accurate fundamental parameters of 14 giants using spectroscopic data. The large discrepancies between photometric and spectroscopic values of [Fe/H] emphasize the need for further detailed spectroscopic follow-up of the Kepler targets. This is mandatory to be able to produce reliable constraints for detailed asteroseismic analyses and for the interpretation of possible exo-planet candidates found around giant stars.

description: The electronic structure of Bi2Se3 is studied by angle-resolved photoemission and density functional theory. We show that the instability of the surface electronic properties, observed even in ultra-high-vacuum conditions, can be overcome via in-situ potassium deposition. In addition to accurately setting the carrier concentration, new Rashba-like spin-polarized states are induced, with a tunable, reversible, and highly stable spin splitting. Ab-initio slab calculations reveal that these Rashba state are derived from the 5QL quantum-well states. While the K-induced potential gradient enhances the spin splitting, this might be already present for pristine surfaces due to the symmetry breaking of the vacuum-solid interface.

Longitudinal investigation of the role of coping on the relationship between dimensions of perfectionism and athletic burnout in sport
Creators: name: Riendeau, Coralie
Publisher: name: University of British Columbia
Year: 2014

description: Perfectionism in athletes is a personality disposition that influences cognitive processes and behaviour (Hall, Hill, & Appleton, 2012). Perfectionism involves two dimensions: personal standards perfectionism (PSP) and evaluative concerns perfectionism (ECP). These dimensions are typically associated with positive and negative outcomes, respectively (Gotwals, Stoeber, Dunn, & Stoll, 2012). Perfectionism has shown important relationships with athlete burnout (Hill, 2013), a psychological symptom that involves emotional and physical exhaustion, perceived reduced accomplishment, and sport devaluation (Raedeke, 1997). One mechanism that is thought to influence the perfectionism-burnout relationship is coping. Cross-sectional research has found that task-oriented coping (TOC) is typically positively associated with PSP and negatively associated with burnout whereas disengagement oriented coping (DOC) is associated negatively with PSP and positively with ECP and burnout (Hill, Hall, & Appleton, 2010a). The purpose of this study was to investigate the mediation effect of coping strategies on the relationship between dimensions of perfectionism and burnout over the course of an athletic season. University level varsity athletes (nfemale = 90; nmale = 35) participated in a longitudinal study involving four time points, each approximately 4-5 weeks apart. The findings revealed that PSP was a negative predictor of burnout whereas ECP was a positive predictor of athletic burnout. Mediation analyses at the within- and between-individual level supported the mediation effect of DOC on the relationship between ECP and burnout and the mediation effect of TOC on the relationship between PSP and burnout. Secondary longitudinal analyses revealed linear decrease in burnout and TOC over a four month period. Quadratic growth models accounted for the change in PSP and DOC during the athletic season. Finally, test of the 2 x 2 model of dispositional perfectionism (Gaudreau & Thompson, 2010) indicated that pure PSP was associated with lower burnout than non-perfectionism, pure ECP was linked with the highest burnout level, and mixed perfectionism was associated with higher burnout than pure PSP. The results revealed consistent relationships between perfectionism, coping, and burnout over time. Overall the study highlighted the role of coping in the relationship between dimensions of perfectionism and athletic burnout.

description: In a series of papers we study the stellar dynamics of the grand design barred-spiral galaxy NGC~1300. In the first paper of this series we estimate the gravitational potential and we give it in a form suitable to be used in dynamical studies. The estimation is done directly from near-infrared observations. Since the 3D distribution of the luminous matter is unknown, we construct three different general models for the potential corresponding to three different assumptions for the geometry of the system, representing limiting cases. A pure 2D disc, a cylindrical geometry (thick disc) and a third case, where a spherical geometry is assumed to apply for the major part of the bar. For the potential of the disc component on the galactic plane a Fourier decomposition method is used, that allows us to express it as a sum of trigonometric terms. Both even and odd components are considered, so that the estimated potential accounts also for the observed asymmetries in the morphology. For the amplitudes of the trigonometric terms a smoothed cubic interpolation scheme is used. The total potential in each model may include two additional terms (Plummer spheres) representing a central mass concentration and a dark halo component, respectively. In all examined models, the relative force perturbation points to a strongly nonlinear gravitational field, which ranges from 0.45 to 0.8 of the axisymmetric background with the pure 2D being the most nonlinear one. We present the topological distributions of the stable and unstable Lagrangian points as a function of the pattern speed $(Ω_p)$. In all three models there is a range of $Ω_p$ values, where we find multiple stationary points whose stability affects the overall dynamics of the system.

description: In an optical superlattice of triple wells, containing two mutually interacting atom species in adjacent wells, we show that one species can be transported through the positions of the other species, yet avoiding significant overlap and direct interaction. The transfer protocol is optimized to be robust against missing atoms of either species in any lattice site, as well as against lattice fluctuations. The degree and the duration of the inter-species overlap during passage can be tuned, making possible controlled large-scale interaction-induced change of internal states.

description: We report on quasi-two-dimensional granular systems in which either one or two large balls is fluidized by an upflow of air in the presence of a background of several hundred smaller beads. A single large ball is observed to propel ballistically in nearly circular orbits, in direct contrast to the Brownian behavior of a large ball fluidized in the absence of this background. Further, the large ball motion satisfies a Langevin equation with an additional speed-dependent force acting in the direction of motion. This results in a non-zero average speed of the large ball that is an order of magnitude faster than the root mean square speed of the background balls. Two large balls fluidized in the absence of the small-bead background experience a repulsive force depending only on the separation of the two balls. With the background beads present, by contrast, the ball-ball interaction becomes velocity-dependent and attractive. The attraction is long-ranged and inconsistent with a depletion model; instead, it is mediated by local fluctuations in the density of the background beads which depends on the large balls' motion.

description: The Westerbork Radio Synthesis Telescope, WSRT, has been used to make a deep radio survey of an ~ 1.7 sq degree field coinciding with the AKARI North Ecliptic Pole Deep Field. The observations, data reduction and source count analysis are presented, along with a description of the overall scientific objectives. The survey consisted of 10 pointings, mosaiced with enough overlap to maintain a similar sensitivity across the central region that reached as low as 21 microJy per beam at 1.4 GHz. A catalogue containing 462 sources detected with a resolution of 17"x15" is presented. The differential source counts calculated from the WSRT data have been compared with those from the shallow VLA-NEP survey of Kollgaard et al 1994, and show a pronounced excess for sources fainter than ~ 1 mJy, consistent with the presence of a population of star forming galaxies at sub-mJy flux levels. The AKARI North Ecliptic Pole Deep field is the focus of a major observing campaign conducted across the entire spectral region. The combination of these data sets, along with the deep nature of the radio observations will allow unique studies of a large range of topics including the redshift evolution of the luminosity function of radio sources, the clustering environment of radio galaxies, the nature of obscured radio-loud active galactic nuclei, and the radio/far-infrared correlation for distant galaxies. This catalogue provides the basic data set for a future series of paper dealing with source identifications, morphologies, and the associated properties of the identified radio sources.

Geophysical survey decomposition and efficient 3D inversion of time-domain electromagnetic data

Publisher: name: University of British Columbia

description: Rigorous three-dimensional (3D) forward and inverse modeling of geophysical electromagnetic (EM) data can be time-consuming and may require a large amount of memory on expensive computers. In this thesis, a novel framework, called survey decomposition, is proposed to make the 3D EM modeling more efficient. Recognizing the multi-scale nature of the EM modeling problems, the fundamental idea is to break down an EM survey, which consists of many transmitters, receivers and times/frequencies, into a number of subproblems, each of which is only concerned about data modeled by a localized source, receiver and time/frequency. The modeling is then carried out on the subproblems at different scales, instead of the original problem as a whole. Such a decomposition is able to speed up the numerical modeling, because: (1) A subproblem can have highly efficient discretizations in space and time customized to its localized source, receiver, time/frequency and the specific scale of investigation, for example, it uses a local mesh that is much smaller than the one used in the original global problem; (2) A subproblem is a self-contained EM modeling problem that does not depend on other subproblems, so it is suitable for massive parallelization; (3) Upon decomposition, no modeling is carried out on the global mesh and the amount of computation is proportional to the number of subproblems, so the scalability improves significantly. After decomposition, the large number of subproblems is further reduced by adaptive, random and dynamic subsampling of the data. The adaptive scheme matches the number of samples to the scale of investigation so that only the data necessary for the model reconstruction are selected. The framework of survey decomposition is applied to two types of time-domain EM (TEM) surveys: airborne TEM and ground large loop TEM. Both synthetic and field data are inverted using this new approach. I show that survey decomposition is capable of producing modeling and inversion results similar to those from the conventional methods with greatly reduced time and memory usage. Further speed-up by massive parallelization and generalization to other types of EM surveys is straightforward.

description: Multifarious image enhancement algorithms have been used in different applications. Still, some algorithms or modules are imperfect for practical use. When the image enhancement modules have been fixed or combined by a series of algorithms, we need to repair them as a whole part without changing the inside. This report aims to find an algorithm based on trained filters to repair low-quality image enhancement modules. A brief review on basic image enhancement techniques and pixel classification methods will be presented, and the procedure of trained filters will be described step by step. The experiments and result comparisons for this algorithm will be described in detail.

description: Nemoura magniseta sp. n. (Figs. 7-8) Material examined. Holotype ♂ from Sapa, Fan Si Pang Mountains, Lao Cai Province, Vietnam, 25-30 March 1995, W. Mey (ZMB). Adult habitus. General color brown. Basal antennal segment pale, second antennal segment dark brown, rest of antennae uniformly brown. Head dark brown. Pronotum brown with some darker rugosities. Legs uniformly pale brown. Male. Forewing length 6 mm. Terga 9-10 without conspicuous setation. Epiproct slightly longer than wide and bears two pairs of slender apical lobes (Fig. 7); slender, straight inner lobes extend beyond outwardly directed, and more heavily sclerotized lateral lobes. Outer paraproct lobe large, unarmed, but with a small mesoapical projection; inner lobes small and unarmed (Fig. 8). Cercal segments curved strongly inward; sclerotized outer margins bear a low knob in basolateral third; inner margins bear a single prominent seta at midlength. Vesicle of moderate length; greatest width near apex (Fig. 8). Female. Unknown. Larva. Unknown. Etymology. The species name refers to the enlarged inner marginal cercal seta. Diagnosis. This species appears distinct from others in the genus by virtue of the enlarged, spine-like seta projecting from the inner cercal margin and by the small rounded knob on the outer cercal margin (Fig. 7). The thick setal-like projection on the ventral cercal margin suggests this species is a member of the Cercispinosa Complex recognized by Baumann (1975).

3-D Digital Image Correlation using a single color-camera
Creators: name: Gubbels, Wade
Publisher: name: University of British Columbia
Year: 2014

description: Digital Image Correlation (DIC) is an optical and numerical method capable of accurately providing full-field, two-dimensional (2-D) and three-dimensional (3-D) surface displacements and strains. 3-D DIC is typically done using two cameras that view the measured object from differing oblique directions. The measured images are independent and must be spatially connected using a detailed calibration procedure. This places a large demand on the practitioner, the optical equipment and the computational method. A novel approach is presented here where a single color-camera is used in place of multiple monochrome cameras. The color-camera measures three independent Red-Green-Blue (RGB) color-coded images. This feature greatly reduces the scale of the required system calibrations and spatial computations because the color images are physically aligned on the camera sensor. The in-plane surface displacements are obtained by performing traditional 2-D DIC in a single color. The out-of-plane information is obtained by a second 2-D DIC analysis and triangulation using oblique illumination from a differently colored light source. Further, the camera perspective errors associated with out-of-plane displacements can independently be measured during this second DIC analysis of the oblique illumination pattern. The 3-D Digital Image Correlation is completed by combining the 2-D correlations for each color. The design and creation of an example apparatus is described here. Experimental results show that the single-camera method can measure 3-D displacements with to within 1% error, with precision of the in-plane and out-of-plane measurements being consistently less than 0.04 and 0.12 pixels, respectively.

description: The surface states of ABC-stacked few-layer graphene (FLG) are studied based on density-functional theory. These states form flat bands near the Fermi level, with the k-space range increasing with the layer number. Based on a tight-binding model, the characteristics of these surface states and their evolution with respect to the number of layers are examined. The infrared optical conductivity is then calculated within the single-particle excitation picture. We show that the surface states introduce unique peaks at around 0.3 eV in the optical conductivity spectra of ABC-stacked FLG when the polarization is parallel to the sheets, in good agreement with recent experimental measurement. Furthermore, as the layer number increases, the absorption amplitude is greatly enhanced and the peak position red-shifts, which provides a feasible way to identify the number of layers for ABC-stacked FLG using optical conductivity measurements.

description: The future of EU International Cultural Relations (ICR) will depend upon factors which this policy paper presents as internal and external to the EU. In reality, they influence each other and transcend political borders. The rise ofpopulist and nationalist forces takes place both within and outside Europe. The global nature of the challenges humanity faces in terms of trust, tolerance and education affect in different ways all countries and transversally impact our capacity to achieve sustainable development. Hard power seems to be gaining prominence over soft power and persuasion. Uses of soft power (and propaganda) persist in the framework of identity politics, where culture is increasingly regarded as a set of national features defined in oppositions to others, rather than a tool for dialogue and cooperation. In whatever direction these factors evolve, the foresight analysis presented in this paper points at a key finding: investing in stronger EU cooperation in International Cultural Relations, rather than Cultural Diplomacy, remains the best solution for EU leadership. An EU strategic approach to ICR rooted in development policy and inter-cultural dialogue bears the promise to facilitate cooperation among EU institutions, member states (MS) and their cultural institutes, as well as broader cultural networks based on innovative models. An approach based on subsidiarity and arm’s length relations with cultural actors can serve EU’s interests better than a top-down Cultural Diplomacy. However, a series of criticalities could potentially affect this emerging policy, which calls for some recommendations on the process and content of the approach under development.
