description: 2M1938+4603 (KIC 9472174) displays a spectacular light curve dominated by a strong reflection effect and rather shallow, grazing eclipses. The orbital period is 0.126 days, the second longest period yet found for an eclipsing sdB+dM, but still close to the minimum 0.1-d period among such systems. The phase-folded light curve was used to detrend the orbital effects from the dataset, and the resulting amplitude spectrum shows a rich collection of pulsation peaks spanning frequencies from ~50 to 4500 uHz. The presence of a complex pulsation spectrum in both the p-mode and the g-mode regions has never been seen before in a compact pulsator. Eclipsing sdB+dM stars are very rare, with only seven systems known and only one with a pulsating primary. Pulsating stars in eclipsing binaries are especially important since they permit masses derived from seismological model fits to be cross checked with orbital mass constraints. We present a first analysis of this star based on the Kepler 9.7-day commissioning light curve and extensive ground-based photometry and spectroscopy that allow us to set useful bounds on the system parameters. We derive a radial-velocity amplitude K_1 = 65.7 +/- 0.6 km/s, inclination angle i = 69.45 +/- 0.20 degrees, and find that the masses of the components are M_1 = 0.48 +/- 0.03 and M_2 = 0.12 +/- 0.01 solar masses.

description: We compute the quantum effective action induced by integrating out fermions in Yang-Mills matrix models on a 4-dimensional background, expanded in powers of a gauge-invariant UV cutoff. The resulting action is recast into the form of generalized matrix models, manifestly preserving the SO(D) symmetry of the bare action. This provides noncommutative (NC) analogs of the Seeley-de Witt coefficients for the emergent gravity which arises on NC branes, such as curvature terms. From the gauge theory point of view, this provides strong evidence that the NC N=4 SYM has a hidden SO(10) symmetry even at the quantum level, which is spontaneously broken by the space-time background. The geometrical view proves to be very powerful, and allows to predict non-trivial loop computations in the gauge theory.

Viral protease disruption of host transcription and translation factors in the pathogenesis of coxsackievirus B3 induced viral myocarditis

description: Myocarditis, inflammation of the heart muscle, is a spectrum of conditions causing significant morbidity and mortality, yet scientific and clinical knowledge related to this entity is limited. One of the most common and best studied causes of myocarditis is infection by coxsackievirus B3 (CVB3). An improved understanding of the science behind CVB3 myocarditis is critical to establishing better diagnostic and therapeutic strategies for affected individuals. CVB3 infection redirects numerous cellular pathways from physiologic processes to viral replication, often mediated by viral proteases. Two viral targets in this process are death associated protein 5 (DAP5) and nuclear pore complex protein 98 (Nup98). DAP5 is a translation initiation factor specific to internal ribosome entry site (IRES) mediated translation. Nup98 is a component of the nuclear pore complex and a transcription factor. In this thesis, I hypothesize that viral proteases contribute to the pathogenesis of viral myocarditis through interaction with DAP5 and Nup98, redirecting translation and transcription towards viral replication. Using in vitro (plasmid expressed viral proteases), in situ (CVB3 infection in cell culture), and in vivo (mouse myocarditis model) models, I demonstrate that viral protease 2A is responsible for the cleavage of DAP5 and Nup98 during CVB3 infection. Both cleavage events I show to be integral to the viral lifecycle using over expression of recombinant fragments and siRNA inhibition of that expression. These results suggest two previously unidentified targets for improved diagnostics and therapeutics for myocarditis, both areas for future research.

description: Abstract: The shareholder wealth consists of dividends and capital gains. The former is considered to be risk averse, whereas the latter is perceived to be risky. The risk return trade off in these two returns drives the investor preference. The objective of a for profit organization is to maximize shareholders’ wealth, however, disbursing dividends may not always be in the best interest of shareholders. Theoretically, retained earnings increase share prices as firms have more funds to be invested. The objective of the study is to measure the stimulus of cash dividends on share prices. We conduct empirical analysis based on data relating to companies listed on the Colombo Stock Exchange (CSE) under the manufacturing sector. As we show in our literature review, in order to reduce the risk of obtaining spurious results, this analysis requires the use of advanced modelling techniques allowing to model non stationarity of time series, as well the presence of control variables and lagged variables. The novelty of our study is in the use of advanced modelling and data visualisation techniques (including the ‘xdPlot’ dataviz framework recently proposed by the authors), especially in application to CSE data. We conduct a thorough exploratory data analysis (EDA) aiming to spot data anomalies and initiate appropriate data transformations. Given the results of EDA and the nature of the data available, we select the Arellano Bond estimator as the most adequate method for regression analysis. Market Price per share (MPS) termed as the dependent variable, whereas Dividend per Share (DPS) is viewed as the independent variable. The results validated theoretical literature such as signaling effect and bird in hand theory, but questioned some previous empirical studies. The study validated cash dividends as stimulus to investors given the positive relationship between DPS and MPS.

description: Results of 75As NMR and NQR measurements are reported for superconducting samples of LaFeAsO1-xFx with various x values. The x dependent widths of the superconducting transition and those of the NQR spectra indicate that the optimally doped LaFeAsO1-xFx sample with the superconducting transition temperature Tc ~28 K has the smallest width or smallest inhomogeneity of the superconducting order parameter Δ. In the analyses of the temperature (T) dependence of the NMR longitudinal relaxation rate 1/T1, we have tried to use a simple relation 1/T1 ~ T^n to see how fast 1/T1 decreases when the superconducting order parameter grows. The relation holds rather well in the T region of ~0.3Tc < T =< Tc, and n varies from 2.5-6 with varying x, having the maximum value 5-6 at the optimal x. These results indicate that the x dependence of n originates from the spatial distribution of Δ, and that the T^{5-6} behavior is considered to be intrinsic to this system.

description: X-ray observations of solar flares routinely reveal an impulsive high-energy and a gradual low-energy emission component, whose relationship is one of the key issues of solar flare study. The gradual and impulsive emission components are believed to be associated with, respectively, the thermal and nonthermal components identified in spectral fitting. In this paper, a prominent about 50 second hard X-ray (HXR) pulse of a simple GOES class C7.5 flare on 20 February 2002 is used to study the association between high energy, non-thermal and impulsive evolution, and low energy, thermal and gradual evolution. We use regularized methods to obtain time derivatives of photon fluxes to quantify the time evolution as a function of photon energy, obtaining a break energy between impulsive and gradual behavior. These break energies are consistent with a constant value of about 11 keV in agreement with those found spectroscopically between thermal and non-thermal components, but the relative errors of the former are greater than 15% and much greater than the a few percent errors found from the spectral fitting. These errors only weakly depend on assuming an underlying spectral model for the photons, pointing to the current data being inadequate to reduce the uncertainties rather than there being a problem associated with an assumed model. The time derivative method is used to test for the presence of a 'pivot energy' in this flare. Although these pivot energies are marginally consistent with a constant value of about 9 keV, its values in the HXR rise phase appear to be lower than those in the decay phase.

Substantial reduction of Stone-Wales activation barrier in fullerene

description: Stone-Wales transformation is a key mechanism responsible for growth, transformation, and fusion in fullerene, carbon nanotube and other carbon nanostructures. These topological defects also substantially alter the physical and chemical properties of the carbon nanostructures. However, this transformation is thermodynamically limited by very high activation energy (\sim 7 eV in fullerene), which can get reduced due to the presence of hydrogen, extra carbon atom, or due to endohedral metal doping. Using first-principles density functional calculations, we show that the substitutional boron doping substantially reduces the Stone-Wales activation barrier (from \sim 7 eV to 2.54 eV). This reduction is the largest in magnitude among all the mechanisms of barrier reduction reported till date. Analysis of bonding charge density and phonon frequencies suggests that the bond weakening at and around the active Stone-Wales site in B-heterofullerene is responsible for such reduction. The formation of Stone-Wales defect is, therefore, promoted in such heterofullerenes, and is expected to affect their proposed H2 storage properties. Such substitutional doping can also modify the Stone-Wales activation barrier in carbon nanotube and graphene naonostructures, and catalyze isomerization, fusion, and nanowelding processes.

Measurements of underlying-event properties using neutral and charged particles in pp collisions at 900 GeV and 7 TeV with the ATLAS detector at the LHC

description: We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events were selected using a minimum-bias trigger which required a charged particle in scintillation counters on either side of the interaction point. Particle flows, sensitive to the underlying event, are measured using clusters of energy in the ATLAS calorimeters, taking advantage of their fine granularity. No Monte Carlo generator used in this analysis can accurately describe the measurements. The results are independent of those based on charged particles measured by the ATLAS tracking systems and can be used to constrain the parameters of Monte Carlo generators.

Shear-induced structuration of confined carbon black gels: Steady-state features of vorticity-aligned flocs

description: Various dispersions of attractive particles are known to aggregate into patterns of vorticity-aligned stripes when sheared in confined geometries. We report a thorough experimental investigation of such shear-induced vorticity alignment through direct visualization of carbon black gels in both simple plane shear and rotational shear cells. Control parameters such as the gap width, the strain rate, and the gel concentration are systematically varied. It is shown that in steady states the wavelength of the striped pattern depends linearly on the gap width $h$ while being insensitive to both the gel concentration $C$ and the shear rate $\gp$. The width of the vorticity-aligned flocs coincides with the gap width and is also independent of $C$ and $\gp$, which hints to a simple picture in terms of compressible cylindrical flocs. Finally, we show that there exists a critical shear rate $\gp_c$ above which structuration does not occur and that $\gp_c$ scales as $h^{-α}$ with $α=1.4\pm 0.1$ independently of $C$. This extensive data set should open the way to quantitative modelling of the vorticity alignment phenomenon in attractive colloidal systems.

Former students' perceptions of the impact of their alternative education experiences : a narrative inquiry
Creators: name: Hofer, Gigi
Publisher: name: University of British Columbia
Year: 2016

description: Large numbers of North American youth are disengaging from and dropping out of school. These youth are increasingly either being placed in, or electing to attend a growing number of alternative education programs (AEPs). Unfortunately, attendance at AEPs often results in the further marginalization of struggling students because (a) relatively little research has identified effective practices within AEPs and (b) negative conceptions of AEPs and of the students who attend them abound. To contribute to the growing body of research identifying effective alternative education practices and to provide an authentic view of these contexts and youth, I examined former students’ perceptions of (a) their experiences in AEPs and (b) the impact their experiences in AEPs had on their lives both during and after attendance. Two semi-structured narrative interviews were conducted with six participants who attended four different AEPs. All participants were female—no males volunteered to participate. The first research interview captured participants’ perspectives on their experiences at the AEPs generally. The second focussed on their perceptions of whether and how characteristics of the AEPs addressed their needs and were linked to outcomes both during and after they attended the programs. Holistic-content analyses identified themes within interviews and a thematic analysis identified themes across narratives. Interviews with former teachers and document analyses provided additional contextual information. The former AEP student participants described characteristics of the AEPs they attended that they perceived addressed their unique and varied social, emotional, and academic needs and facilitated their success, not only while they were attending, but beyond their time at the AEPs. Analyses revealed seven predominant themes across their narratives: relationships with a key teacher and with other students; counselling services; the identification, use, and development of personal strengths; flexibility and structure in the organization of academic learning; life skills learning; exercising control over the goings-on and culture at the AEP; and a homelike physical set-up. My study contributes to the promising new field of research investigating the impact of AEP practices from the perspective of students. This approach contrasts the majority of previous research that has ignored the voices of these key stakeholders.

description: Pion pion scattering is studied in a generalized linear sigma model which contains two scalar nonets (one of quark-antiquark type and the other of diquark-antidiquark type) and two corresponding pseudoscalar nonets. An interesting feature concerns the mixing of the four isosinglet scalar mesons which yield poles in the scattering amplitude. Some realism is introduced by enforcing exact unitarity via the K-matrix method. It is shown that a reasonable agreement with experimental data is obtained up to about 1 GeV. The poles in the unitarized scattering amplitude are studied in some detail. The lowest pole clearly represents the sigma meson (or f0(600)) with a mass and decay width around 500 MeV. The second pole invites comparison with the f0(980) which has a mass around 1 GeV and decay width around 100 MeV. The third and fourth poles, resemble some of the isosinglet state in the complicated 1-2 GeV region. Some comparison is made to the situation in the usual SU(3) linear sigma model with a single scalar nonet.

description: This paper presents a simple and effective wideband method for the determination of material properties, such as the complex index of refraction and the complex permittivity and permeability. The method is explicit (non-iterative) and reference-plane invariant: it uses a certain combination of scattering parameters in conjunction with group-velocity data. This technique can be used to characterize both dielectric and magnetic materials. The proposed method is verified experimentally within a frequency range between 2 to 18 GHz on polytetrafluoroethylene and polyvinylchloride samples. A comprehensive error and stability analysis reveals that, similar to other methods based on transmission/reflection measurement, the uncertainties are larger at low frequencies and at the Fabry-Perot resonances.

description: Consider a small sample coupled to a finite number of leads, and assume that the total (continuous) system is at thermal equilibrium in the remote past. We construct a non-equilibrium steady state (NESS) by adiabatically turning on an electrical bias between the leads. The main mathematical challenge is to show that certain adiabatic wave operators exist, and to identify their strong limit when the adiabatic parameter tends to zero. Our NESS is different from, though closely related with the NESS provided by the Jak{\v s}i{ć}-Pillet-Ruelle approach. Thus we partly settle a question asked by Caroli {\it et al} in 1971 regarding the (non)equivalence between the partitioned and partition-free approaches.

description: The electromagnetic charge operator in a two-nucleon system is derived in chiral effective field theory ($χ$EFT) up to order $e\, Q$ (or N4LO), where $Q$ denotes the low-momentum scale and $e$ is the electric charge. The specific form of the N3LO and N4LO corrections from, respectively, one-pion-exchange and two-pion-exchange depends on the off-the-energy-shell prescriptions adopted for the non-static terms in the corresponding potentials. We show that different prescriptions lead to unitarily equivalent potentials and accompanying charge operators. Thus, provided a consistent set is adopted, predictions for physical observables will remain unaffected by the non-uniqueness associated with these off-the-energy-shell effects.

description: We present new optical spectroscopy of the gamma-ray binary LS 5039. Our data show evidence for sub-orbital modulation in the radial velocities with amplitude ~7 km/s and period ~Porb/4. This short-term oscillation is stable over at least 7 years and it is likely triggered by non-radial oscillations of the O6.5V optical star. We also present the results of a spectroscopic campaign on MWC 148, the optical counterpart of the new gamma-ray binary candidate HESS J0632+067. Long-term variations in the Halpha and Hbeta emission line parameters are clearly detected which, if modulated with the binary orbit, would imply a period >200 days.

description: Galaxy cluster surveys based on the Sunyaev-Zeldovich effect (SZE) mapping are expected from ongoing experiments. Such surveys are anticipated to provide a significant amount of information relevant to cosmology from the number counts redshift distribution. We carry out an estimation of predicted SZE counts and their redshift distribution taking into account the current cosmological constraints and the X-ray cluster temperature distribution functions. Comparison between local and distant cluster temperature distribution functions provides evidence for an evolution in the abundance of X-ray clusters that is not consistent with the use of standard scaling relations of cluster properties in the framework of the current concordance model. The hypothesis of some evolution of the scaling law driven by non-gravitational processes is a natural solution to this problem. We perform a MCMC statistical study using COSMOMC, combining current CMB observations from WMAP, the SNIa Hubble diagram, the galaxy power spectrum data from SDSS and X-ray clusters temperature distributions to predict SZE cluster number counts. Models reproducing well the X-ray cluster temperature distribution function evolution lead to a significantly lower SZE clusters number counts with a distinctive redshift distribution. Ongoing microwave SZE surveys will therefore shed new light on intracluster gas physics and greatly help to identify the role of possible non-gravitational physics in the history of the hot gas component of x-ray clusters.

description: We implement magnetic resonance force microscopy (MRFM) in an experimental geometry, where the long axis of the cantilever is normal to both the external magnetic field and the RF microwire source. Measurements are made of the statistical polarization of $^1$H in polystyrene with negligible magnetic dissipation, gradients greater than $10^5$ T/m within 100 nm of the magnetic tip, and rotating RF magnetic fields over 12 mT at 115 MHz. This geometry could facilitate the application of nanometer-scale MRFM to nuclear species with low gyro-magnetic ratios and samples with broadened resonances, such as In spins in quantum dots.

Understanding the performance gap : an evaluation of the energy efficiency of three high-performance buildings in British Columbia
Creators: name: Chu, Anne-Mareike
Publisher: name: University of British Columbia
Year: 2016

description: The market shift towards high-performance buildings has been brought into question by growing concerns about the actual energy efficiency of these projects. Research studies have been pointing increasingly to performance gaps between the predicted (or modelled) and actual (or measured) energy consumption of certified ‘green’ buildings. Discussions about reasons for performance gaps have been recurring in the building industry and research alike. This thesis investigates the energy performance gap of three high-performance LEED-certified buildings in British Columbia: the Centre for Interactive Research on Sustainability (CIRS), the Jim Pattison Centre of Excellence in Sustainable Building Technology and Renewable Energy Conversation (JPCE) and the District Education Centre (DEC). For each case study, an energy performance evaluation reveals differences between modelled and measured energy consumption. Based on an extensive literature review, the reasons for identified performance gaps are explored through expert interviews with key stakeholders that were involved in the design, construction or operation of each of these projects. The energy performance evaluation reveals significant performance gaps in all three case studies, with one project out-performing and two under-performing the design predictions. The research highlights a lack of consistent metered-energy data at the system level. Based on these findings this study attempts to evaluate key sources of performance issues, in the context of the three case-study buildings. It shows that performance-gap reasons indicated in the literature occurred at all phases of the building lifecycle: starting at the planning/design and modelling phase, through the construction, commissioning and handover phases, to the building operation and occupancy phase. The results suggest that performance gaps are closely related to shortcomings in energy design concepts, development procedures, and operational practices that were applied in the three buildings. The research emphasizes the importance of creating a greater transparency of development procedures and collaborative approaches to successfully design, build and operate high-performance buildings. The challenges faced by project teams to integrate innovative technologies calls for robust design solutions and methodologies that can be easily translated into implementation strategies and operation procedures that meet building management capacities.

description: Die Smart Factory, auch als intelligente Fabrik bezeichnet, steht als Synonym für die Schaffung von effektiven und flexiblen Produktionsumgebungen in der Industrie durch Digitalisierung und cyber-physische Systeme. Um Fertigungs- und Produktionsanlagen flexibel und effizient in den Produktionsablauf zu integrieren, spielt auch die Einbindung von mobilen Anwendungen im Bereich des Maschinenbaus und deren Komponenten eine wichtige Rolle. Ermöglicht wird die intelligente Fabrik u.a. auch durch die Verwendung kompakter mechatronischer Systeme und deren Teilkomponenten wie Sensoren, Aktoren und der dazugehörigen Mikroelektronik. Hier stellt sich die Frage, wie die Energiezuführung und die Datenanbindung flexibel zu solchen mobilen Anwendungen bzw. zu den intelligenten mechatronischen Systemen bereitgestellt werden kann. Diese Dissertation liefert einen Beitrag zur Entwicklung eines intelligenten Aktors im Bereich der berührungslosen induktiven Energie- und Datenübertragung für mobile Anwendungen bzw. beweglichen elektrischen Verbrauchern. Das vorgestellte neue Konzept zeigt den Aufbau und die Realisierung des intelligenten Aktors. In einem ersten Schritt wird ein induktives kontaktloses Energieübertragungssystem an einem Funktionsmuster aufgebaut. Auf Grundlage einer OFDM-basierten Datenkommunikation und durch die Integration eines entwickelten Zeitstempelverfahrens sind eine Kommunikation und Synchronisation am Funktionsmuster über das kontaktlose Energieübertragungssystem möglich. Dabei wird auch gezeigt, dass sich die Taktfrequenz für die Synchronisierungsvorgänge bei der Übertragung von Daten zwischen den einzelnen Kommunikationsteilnehmern deutlich reduzieren lässt. Untersucht wird dabei die Ganggenauigkeit bzw. die Frequenzkonstanz von verschiedenen Oszillatorklassen. Im weiteren Verlauf der Arbeit werden der Entwurf und die Entwicklung einer Hardware- und Regelungsplattform für einen intelligenten Aktor gezeigt und erarbeitet. Innerhalb eines SoPC-basierten Embedded Systems wird ein kompaktes und skalierbares Motorsteuerkonzept für den Betrieb einer PMSM vorgestellt. Im letzten Teil der Arbeit wird die Entwicklung und die Umsetzung eines prädiktiven Regelungsverfahrens in einer durchgeführten Simulation vorgestellt. In der Simulation werden die Vorteile und die Leistungsfähigkeit der MPC-Regelung im Vergleich zu einer klassischen PID-Kaskadenregelung für das Stör- und Führungsverhalten für den Betrieb einer PMSM aufgezeigt.

description: Abstract:
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

A differential chemical element analysis of the metal poor Globular Cluster NGC 6397

description: We present chemical abundances in three red giants and two turn-off stars in the metal poor Galactic globular cluster (GC) NGC 6397 based on spectroscopy obtained with the MIKE high resolution spectrograph on the Magellan 6.5-m Clay telescope. Our results are based on a line-by-line differential abundance analysis relative to the well-studied red giant Arcturus and the Galactic halo field star Hip 66815. At a mean of -2.10 +/- 0.02 (stat.) +/- 0.07 (sys.) the differential iron abundance is in good agreement with other studies in the literature based on gf-values. As in previous, differential works we find a distinct departure from ionization equilibrium in that the abundances of Fe I and Fe II differ by ~0.1 dex, with opposite sign for the RGB and TO stars. The alpha-element ratios are enhanced to 0.4 (RGB) and 0.3 dex (TO), respectively, and we also confirm strong variations in the O, Na, and Al/Fe abundance ratios. Accordingly, the light-element abundance patterns in one of the red giants can be attributed to pollution by an early generation of massive SNe II. TO and RGB abundances are not significantly different, with the possible exception of Mg and Ti, which is, however, amplified by the patterns in one TO star, additionally belonging to this early generation of GC stars. We discuss interrelations of these light elements as a function of the GC metallicity.

description: Several recent papers discuss gravitational corrections to gauge couplings that depend quadratically on the energy. In the framework of the background-field approach, these correspond in general to adding to the effective action terms quadratic in the field strength but with higher-order space-time derivatives. We observe that such terms can be removed by appropriate local field redefinitions, and do not contribute to physical scattering-matrix elements. We illustrate this observation in the context of open string theory, where the effective action includes, among other terms, the well-known Born-Infeld form of non-linear electrodynamics. We conclude that the quadratically energy-dependent gravitational corrections are \emph{not} physical in the sense of contributing to the running of a physically-measurable gauge coupling, or of unifying couplings as in string theory.

description: By direct numerical simulation of the time-dependent Gross-Pitaevskii equation using the split-step Fourier spectral method we study the double-humped localization of a cigar-shaped Bose-Einstein condensate (BEC) in a one-dimensional bichromatic quasi-periodic optical-lattice potential, as used in a recent experiment on the localization of a BEC [Roati et al., Nature 453, 895 (2008)]. Such states are spatially antisymmetric and are excited modes of Anderson localization. Where possible, we have compared the numerical results with a variational analysis. We also demonstrate the stability of the localized double-humped BEC states under small perturbation.
