description: Challenges like climate change, decreasing resources and rising energy prices require higher energy efficiency. The building sector causes high energy use. An instrument to promote its efficiency is performance contracting (PF). A contractor commits contractually to realize energy efficiency improvements in a building. He refinances the costs by realized energy cost savings. In spite of its advantages PF is rarely applied. The thesis especially treats possibilities and problems for public utility companies with PF as business model. It links scientific findings with practical knowledge and focusses mainly on legal aspects.

description: The Sloan Digital Sky Survey (SDSS), originally targeted at quasi-stellar objects, has provided us with a wealth of astronomical byproducts through the last decade. Since then, the number of white dwarfs (WDs) with physically bound main-sequence star companions (mostly dM stars) has increased radically, allowing for fundamentally new insights into stellar physics. Different methods for the retrieval and follow-up analysis of SDSS WD-dM binaries have been applied in the literature, leading to a rising number of WD-dM catalogs. Here we present a detailed literature search, coupled with our own hunting for SDSS WD-dMs by color selection, the outcome being named the "SDSS White Dwarf - M Star Library". We also explain improvements of our automated spectral analysis method.

description: We extend a general-relativistic ideal magneto-hydrodynamical code to include the effects of elasticity. Using this numerical tool we analyse the magneto-elastic oscillations of highly magnetised neutron stars (magnetars). In simulations without magnetic field we are able to recover the purely crustal shear oscillations within an accuracy of about a few per cent. For dipole magnetic fields between 5 x 10^13 and 10^15 G the Alfvén oscillations become modified substantially by the presence of the crust. Those quasi-periodic oscillations (QPOs) split into three families: Lower QPOs near the equator, Edge QPOs related to the last open field line and Upper QPOs at larger distance from the equator. Edge QPOs are called so because they are related to an edge in the corresponding Alfvén continuum. The Upper QPOs are of the same kind, while the Lower QPOs are turning-point QPOs, related to a turning point in the continuous spectrum.

description: Based on the low energy effective Hamiltonian with naive factorization, we calculate the branching ratios(BRs) and CP asymmetries (CPAs) for the twenty three double charm decays $B/B_s \to D^{(*)}_{(s)} D^{(*)}_{(s)}$ in both the standard model (SM) and the minimal supergravity (mSUGRA) model. Within the considered parameter space, we find that (a) the theoretical predictions for the BRs, CPAs and the polarization fractions in the SM and the mSUGRA model are all consistent with the currently available data within $\pm 2σ$ errors; (b) For all the considered decays, the supersymmetric contributions in the mSUGRA model are very small, less than $7\%$ numerically. It may be difficult to observe so small SUSY contributions even at LHC.

A customizable, multi-stage multi-criteria decision analysis approach for material-supplier selection problem in SMEs : a case study of insulated housing products
Creators: name: Muhammad, Usamah Inam
Publisher: name: University of British Columbia
Year: 2019

description: This research develops a multi-stage multiple criteria decision making (MCDM) approach for combined supplier-selection, material selection problems. The method has been exemplified through an industrial case study on the development of insulated skirting products. Namely, a Canadian distribution company has been long supplying the Canadian market with skirting products for manufactured homes, but recently has had issues with their overseas material supplier, particularly due to increased exchange rates. Hence, it has desired to shift their supply stream to a local manufacturer. There exist a large number of potential manufacturers that would be suitable for this new partnership. It has been crucial to scrutinize the decision alternatives systematically in order to rank and allow for the optimal selection of the supplier(s) and their skirting products. When manufacturing suppliers are changed for a business, a natural consequence is that the end product’s material properties would also change, hence the need for a rigorous material testing as part of a multiple criteria decision making process. A step-by-step procedure has been developed here that combines supplier and material selection sub-decisions in order to find the most suitable alternative, using a hybrid of multiple criteria optimization techniques. The procedure accounts for the required decision accuracy and time-sensitivity measures that a production manager would face under different decision scenarios. The case study shows that if the company’s business situation is time-critical and the decision accuracy may not be of primary concern, a simple non-compensatory MCDM method would suffice. Otherwise, more structured compensatory methods should be employed. The criteria proposed for the case study have been selected based on the company staff feedback. The presented methodology is customizable and may be applied to other similar supplier decision making problems. Correlation analysis has also performed to ensure the independence of the quantitative material criteria, as required per assumptions of the standard MCDM methods.

description: In this paper we study Open Wilson Lines (OWL's) in the context of two Supersymmetric Yang Mills theories. First we consider four dimensional N=2 Supersymmetric Yang Mills Theory with hypermultiplets transforming in the fundamental representation of the gauge group, and find supersymmetric OWL's only in the superconformal versions of these theories. We then consider four dimensional N=4 SYM coupled to a three dimensional defect hypermultiplet. Here there is a semi-circular supersymmetric OWL, which is related to the ray by a conformal transformation. We perform a perturbative calculation of the operators in both theories, and discuss using localization to compute them non-perturbatively.

description: We generalize the proof of Karamata's Theorem by the method of approximation by polynomials to the operator case. As a consequence, we offer a simple proof of \emph{uniform dual ergodicity} for a very large class of dynamical systems with infinite measure, and we obtain bounds on the convergence rate. In many cases of interest, including the Pomeau-Manneville family of intermittency maps, the estimates obtained through real Tauberian remainder theory are very weak. Building on the techniques of complex Tauberian remainder theory, we develop a method that provides \emph{second (and higher) order asymptotics}. In the process, we derive a \emph{higher order Tauberian theorem} for scalar power series, which to our knowledge, has not previously been covered.

description: We use the continuum shell model approach to explore the resonance width distribution in unstable many-body systems. The single-particle nature of a decay, the few-body character of the interaction Hamiltonian, and collectivity that emerges in non-stationary systems due to the coupling to the continuum of reaction states are discussed. Correlations between structures of the parent and daughter nuclear systems in the common Fock space are found to result in deviations of decay width statistics from the Porter-Thomas distribution.

description: The unbundling model of the Independent Transmission Operator comprises the operator owning the assets and belonging to a vertically integrated company (parent company), with special rules to guarantee its independence. The parent company can only pursue its goals through the Supervisory Board. However, there is uncertainty as to the composition according to § 10d para 3 German Energy Act. Especially if codetermination law applies, there is an incompatibility between these two fields of law which manifests itself in the inconsistent composition of the Supervisory Board in practice. Therefore, this paper deals with the interpretation of this provision and the perspectives and possibilities of the actual composition.

Vor allem bei Anwendung des DrittelbG besteht eine Inkompatibilität zwischen energie- und mitbestimmungsrechtlichen Vorgaben, die sich in der uneinheitlichen Zusammensetzung in der Praxis niederschlägt.

description: Rare earth perovskite cobaltites are increasingly recognized as materials of importance due to rich physics and chemistry in their ordered-disordered structure for the same composition. Apart from colossal magnetoresistance effect, like manganites, the different forms of cobaltites exhibit interesting phenomena including spin, charge and orbital ordering, electronic phase separation, insulator-metal transition, large thermoelectric power at low temperature. Moreover, the cobaltites which display colossal magnetoresistance effect could be used as read heads in magnetic data storage and also in other applications depending upon their particular properties. The A-site ordereddisordered cobaltites exhibit ferromagnetism and metal-insulator transitions as well as other properties depending on the composition, size of A-site cations and various external factors such as pressure, temperature, magnetic field etc. Ordered cobaltites, having a 112-type layered structure, are also reported to have an effectively stronger electron coupling due to layered A-site cationic ordering. Most importantly for the present article we focus on La-Ba-Co-O based ordered-disordered perovskite phases, which exhibit interesting magnetic and electron transport properties with ferromagnetic transition, TC ~ 177K, and it being the first member of lanthanide series. Zener double exchange mechanism considered to be crucial for understanding basic physics of the ferromagneticmetallic phase, yet does not explain clearly the insulating-type phase. In terms of electron transport the ferromagnetic-metallic or insulating/semiconducting states have been discussed in the present article with different types of hopping model.

description: It has been shown that four dimensional Brans-Dicke theory with effective matter field and self interacting potential can be achieved from vacuum 5D BD field equations, where we refer to as modified Brans-Dicke theory (MBDT). We investigate a generalized Bianchi type I anisotropic cosmology in 5D BD theory, and by employing obtained formalism, we derive induced-matter on any 4D hypersurface in context of the MBDT. We illustrate that if the usual spatial scale factors are functions of time while scale factor of extra dimension is constant, and scalar field depends on time and fifth coordinate, then in general, one will encounter inconsistencies in field equations. Then, we assume the scale factors and scalar field depend on time and extra coordinate as separated variables in power law forms. Hence, we find a few classes of solutions in 5D spacetime through which, we probe the one which leads to a generalized Kasner relations among Kasner parameters. The induced scalar potential is found to be in power law or in logarithmic form, however, for constant scaler field and even when scalar field only depends on fifth coordinate, it vanishes. The conservation law is indeed valid in this MBDT approach for derived induced energy momentum tensor (EMT). We proceed our investigations for a few cosmological quantities, where for simplicity we assume metric and scalar field are functions of time. Hence, the EMT satisfies barotropic equation of state, and the model indicates that constant mean Hubble parameter is not allowed. Thus, by appealing to variation of Hubble parameter, we assume a fixed deceleration parameter, and set evolution of quantities with respect to the fixed deceleration, BD coupling and state parameters. The WEC allows a shrinking extra dimension for decelerating expanding universe that, in the constant scalar field, evolves same as flat FRW spacetime in GR.

Lipid nanoparticle delivery of small interfering RNA targeting androgen receptor variants for prostate cancer
Creators: name: Quick, Joslyn
Publisher: name: University of British Columbia
Year: 2019

description: Expression of constitutively active splice variants of the androgen receptor (AR) currently poses treatment challenges for advanced stages of prostate cancer. Conventional hormone therapies for prostate cancer target the AR ligand-binding domain, which is completely absent in most AR splice variants. Utilizing small interfering RNA (siRNA) as a genetic drug can provide an approach to target such cancer-promoting variants, but requires a vehicle to prevent premature degradation and promote delivery to the cytosol of diseased cells. This thesis investigates the efficacy of a lipid nanoparticle (LNP) carrier of siRNA that specifically targets all AR variant forms (siARv). Two human prostate cancer models were utilized throughout the studies described here: the 22Rv1 cell line exhibits high expression levels of AR splice variants and growth dependency on the like; LNCaP cell growth is dependent on full-length AR and expresses extremely low levels of splice variant forms. A screen in 22Rv1 cells identified siARv from a panel of siRNAs designed against exon 1 of AR mRNA, a target that enables knockdown of full-length and variant ARs. The ability of a clinical-grade LNP formulation containing siARv to facilitate silencing of ARs was demonstrated in 22Rv1 and LNCaP cells, and it was shown that this knockdown of ARs also affected AR transcriptional activity, as exhibited by reduction of prostate-specific antigen levels in both models upon treatment. It was demonstrated that treatment with siARv-LNP reduced the viability of 22Rv1 cells more effectively than LNP carrying siARfl (siRNA targeting full-length AR mRNA only), whereas the effect on LNCaP cell viability of siARv-LNP and siARfl-LNP was not differentiable. The biodistribution of siARv-LNP formulated for optimal in vivo activity was measured in mice bearing 22Rv1 xenografts, demonstrating a measurable accumulation of LNP at distal tumors. The antitumor activity of the siARv-LNP system was subsequently tested on 22Rv1 xenografts upon repeat dosing, exhibiting slowed tumor progression, as well as enhanced survival, compared to animals treated with siARfl-LNP. These results provide an alternative means to target AR variants by way of LNP-mediated gene therapy, and comment on the relative utility of this approach in treating an AR variant-dependent prostate cancer model.

description: We use direct N-body simulations to investigate the evolution of star clusters with large size-scales with the particular goal of understanding the so-called extended clusters observed in various Local Group galaxies, including M31 and NGC6822. The N-body models incorporate a stellar mass function, stellar evolution and the tidal field of a host galaxy. We find that extended clusters can arise naturally within a weak tidal field provided that the tidal radius is filled at the start of the evolution. Differences in the initial tidal filling-factor can produce marked differences in the subsequent evolution of clusters and the size-scales that would be observed. These differences are more marked than any produced by internal evolution processes linked to the properties of cluster binary stars or the action of an intermediate-mass black hole, based on models performed in this work and previous work to date. Models evolved in a stronger tidal field show that extended clusters cannot form and evolve within the inner regions of a galaxy such as M31. Instead our results support the suggestion many extended clusters found in large galaxies were accreted as members of dwarf galaxies that were subsequently disrupted. Our results also enhance the recent suggestion that star clusters evolve to a common sequence in terms of their size and mass.

description: Molecular flow gas damping of mechanical motion in confined geometries, and its associated noise, is important in a variety of fields, including precision measurement, gravitational wave detection, and MEMS devices. We used two torsion balance instruments to measure the strength and distance-dependence of `squeeze film' damping. Measured quality factors derived from free decay of oscillation are consistent with gas particle superdiffusion in Lévy walks and inconsistent with those expected from traditional Gaussian random walk particle motion. The distance-dependence of squeeze film damping observed in our experiments is in agreement with a parameter-free Monte Carlo simulation. The squeeze film damping of the motion of a plate suspended a distance d away from a parallel surface scales with a fractional power between 1/d and 1/d^2.

description: When a theory shall be described at all scales, it is necessary to start from its elementary degrees of freedom. Herein, one possible chain of steps for this purpose will be briefly outlined for the example of a gauge theory, like QCD. Starting with the elementary constituents, gluons and quarks, step by step the final observables, physical states, will be built up. This process is based on the elementary correlation functions, and uses a combination of both numerical lattice calculations and functional continuum methods. While the process uses a fixed gauge at each intermediate step, the final observables are gauge-invariant.

description: The function that counts the number of ways to place nonattacking identical chess or fairy chess pieces in a rectangular strip of fixed height and variable width, as a function of the width, is a piecewise polynomial which is eventually a polynomial and whose behavior can be described in some detail. We deduce this by converting the problem to one of counting lattice points outside an affinographic hyperplane arrangement, which Forge and Zaslavsky solved by means of weighted integral gain graphs. We extend their work by developing both generating functions and a detailed analysis of deletion and contraction for weighted integral gain graphs. For chess pieces we find the asymptotic probability that a random configuration is nonattacking, and we obtain exact counts of nonattacking configurations of small numbers of queens, bishops, knights, and nightriders.

description: We propose a weighted planar stochastic lattice (WPSL) formed by the random sequential partition of a plane into contiguous and non-overlapping blocks and find that it evolves following several non-trivial conservation laws, namely $\sum_i^N x_i^{n-1} y_i^{4/n-1}$ is independent of time $\forall \ n$, where $x_i$ and $y_i$ are the length and width of the $i$th block. Its dual on the other hand, obtained by replacing each block with a node at its center and common border between blocks with an edge joining the two vertices, emerges as a network with a power-law degree distribution $P(k)\sim k^{-γ}$ where $γ=5.66$ revealing scale-free coordination number disorder since $P(k)$ also describes the fraction of blocks having $k$ neighbours. To quantify the size disorder, we show that if the $i$th block is populated with $p_i\sim x_i^3$ then its distribution in the WPSL exhibits multifractality.

description: Dielectronic recombination (DR) of Na-like Fe$^{15+}$ forming Mg-like Fe$^{14+}$ via excitation of a $2l$ core electron has been investigated. We find that configuration interaction (CI) between DR resonances with different captured electron principal quantum numbers $n$ can lead to a significant reduction in resonance strengths for $n \geq 5$. Previous theoretical work for this system has not considered this form of CI. Including it accounts for most of the discrepancy between previous theoretical and experimental results.

description: The criticism of Babaev and Silaev notwithstanding, we conclude that our analysis is correct. We have found in our papers on two-band superconductors close to Tc, where the Ginzburg-Landau (GL) theory applies, that these materials are characterized by a single order parameter, governed by a single correlation length. In the GL domain, the order parameters of individual bands are proportional to each other. This happens due to the unavoidable inter-band Josephson coupling. Consequently, in the regime where the GL theory applies, these systems are either type-I or type-II superconductors with no room for so called "1.5-type" superconductivity. This conclusion does not mean that at lower temperatures, outside of the GL domain, the inter-vortex interaction cannot have interesting properties, however, the latter cannot be addressed with the standard GL formalism.

A novel star schema attribute induction will be examined with current attribute oriented induction based on characteristic rule and using non rule based concept hierarchy by implementing both of approaches. In novel star schema attribute induction some improvements have been implemented like elimination threshold number as maximum tuples control for generalization result, there is no ANY as the most general concept, replacement the role concept hierarchy with concept tree, simplification for the generalization strategy steps and elimination attribute oriented induction algorithm. Novel star schema attribute induction is more powerful than the current attribute oriented induction since can produce small number final generalization tuples and there is no ANY in the results.

description: Stroke is a common cause of permanent disability accompanied by devastating impairments. Motor, sensory and cognitive deficits are common following stroke, yet treatment is limited. Along with histological measures, functional outcome in animal models has provided valuable insight to the biological basis and potential rehabilitation efforts of experimental stroke. Developing and using tests that identify behavioral deficits is essential to expanding the development of translational therapies. Forelimb Asymmetry Task experiments – often called Cylinder Tests – are used to study the impact of ischemic stroke and its subsequent rehabilitation to contralateral limb movements of studying rodents. Through assessments on qualitative and quantitative aspects of vertical exploration to the Cylinder Wall, extent of locomotor asymmetry is evaluated [25-27]. Traditionally wall rearing assessments are evaluated through manual, stop-watch based measurements that require laborious observations. Methods that automate the process were attempted such as the use of hardware-based sensor detections that passively probes of touches on the sensor grid. In its various implementations, the sensor-based methods fail to specify the limb that rears the wall nor depict the ways forelimbs are coordinated during the rearing. Advent of artificial intelligence (AI) algorithms, notably Deep Neural Networks (DNN), helps to extract posture and coordinates of forelimbs [21]. PalmGrid is the first attempt to exploit AI posture extraction algorithms – based on 50 layers depth in ResNet Deep Neural Networks [29] together with posture extraction algorithm DeepLabCut [24] – to automate the assessment process with 70% detection accuracy using robust, open-source software. Further improvements in deep neural networks precisions, such as increasing its depth or incorporating advanced posture extraction algorithms, will further enhance detection precisions. In this way, we will have viable alternatives to conduct cylinder test experiments without suffering from extra cost burdens and complex calibrations.
Fermi Large Area Telescope Observation of a Gamma-ray Source at the Position of Eta Carinae

description: The Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope detected a gamma-ray source that is spatially consistent with the location of Eta Carinae. This source has been persistently bright since the beginning of the LAT survey observations (from 2008 August to 2009 July, the time interval considered here). The gamma-ray signal is detected significantly throughout the LAT energy band (i.e., up to ~100 GeV). The 0.1-100 GeV energy spectrum is well represented by a combination of a cutoff power-law model (< 10 GeV) and a hard power-law component (> 10 GeV). The total flux (> 100 MeV) is $3.7^{+0.3}_{-0.1} \times 10^{-7}$ photons s$^{-1}$ cm$^{-2}$, with additional systematic uncertainties of 10%, and consistent with the average flux measured by AGILE (Tavani et al. 2009). The light curve obtained by Fermi is consistent with steady emission. Our observations do not confirm the presence of a gamma-ray flare in 2008 October as reported by Tavani et al. (2009), although we cannot exclude that a flare lasting only a few hours escaped detection by the Fermi LAT. We also do not find any evidence for gamma-ray variability that correlates with the large X-ray variability of Eta Carinae observed during 2008 December and 2009 January. We are thus not able to establish an unambiguous identification of the LAT source with Eta Carinae.

description: Misinformation has triggered government inquiries and threatens the perceived legitimacy of campaign processes and electoral outcomes. A new identity polarization has arisen between Remain and Leave sympathizers in the UK Brexit debate, with associated accusations of misinformation use. Competing psychological accounts of how people come to accept and defend misinformation pit self-reinforcing motivated cognition against lack of systematic reasoning as possible explanations. We harness insights from political science, cognitive neuroscience and psychology to examine the impact of trust and identity on information processing regarding Brexit in a group of Remain identifiers. Behaviourally, participants' affective responses to Brexit-related information are affected by whether the emotional valence of the message is compatible with their beliefs on Brexit (positive/negative) but not by their trust in the source of information. However, belief in the information is significantly affected by both (dis)trust in information source and by belief compatibility with the valence of the information. Neuroimaging results confirm this pattern, identifying areas involved in judgements of the self, others and automatic processing of affectively threatening stimuli, ultimately supporting motivated cognition accounts of misinformation endorsement.This article is part of the theme issue ‘The political brain: neurocognitive and computational mechanisms’.
title: Existing and conceptual ship-grillage stiffener optimization through maximizing overload capacity under transverse loads
Creators: name: Norman, Jordan M.
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The HMCS IROQUOIS naval destroyer was decommissioned in 2015. Six ship hull sections have been sent to Memorial University of Newfoundland for detailed structural analyses. An investigation has been undertaken to determine if significant improvements could be made to the IROQUOIS grillage panels. If significant improvements were possible it was important to determine how the grillage could then be optimized. The study focused on grillage stiffener design. Numerous stiffener designs were tested by varying factors related to their geometric and parametrized dimensions. Both finite element analysis and experimental design techniques were implemented within the study. The statistical significance of the studied factors was analyzed to develop more detailed and specific, experiments. Control runs were tested which consisted of built-T and flat bar stiffened panels, as well as the IROQUOIS grillage panels. An optimized concept grillage was produced which demonstrated an ability to outperform the control runs.
The taste of a label : do visual sensory cues on a wine label impact the sensory taste of the wine?

description: The goal of this research is to understand the influence of wine label visual sensory cues on the perceived sensory taste of wine. This five-phase research study uses consumer culture theory as a framework, which views consumers as identity seekers navigating opportunities in the marketplace that provide a message that embraces who they are based on their own experiences (Askegaard & Linnet, 2011). With increasing experience, wine drinkers create associations between verbal and visual cues on the label, that form expectations for how the wine should taste. This study refers to these variables as visual sensory cues, which become associated with sensory attributes and bias the sensory experience of wine. Visual sensory cues on a label help form the brand image of the wine that impacts purchase intent and appeal (Hoegg & Alba, 2007b). Brand image is measured using four categories; brand personality, design style, narratives, and conveyance of luxury. Willingness-to-pay is used as a measurement to assign value to visual sensory cues and determine if this results in a cross-modal sensory association that impacts the taste of the wine. This study uses the epistemological approach of pragmatism to mix methods from different paradigms on their basis of usefulness to addressing the research questions (Collins & Hussey, 2014). These methods include a quantitative online survey using seventeen uniquely classified wine labels. The survey reveals that wine drinkers anticipate a wine will taste better after seeing a label they identify with. An in-person taste shows that wine drinkers were unable to discriminate between two wines using only taste. A second in-person taste test using the same two wines and two uniquely visually classified labels demonstrates that when consumers identify with a label, they believe the wine tastes better. Follow-up in-depth interviews find wine drinkers look for a label that is “for someone like me” and this impacts the overall sensory experience of the wine. The results of this research reveal a cross-modal association that results when a wine label is identified with through visual sensory cues and this process influences the actual taste of the wine.
A multiwavelength approach to BD+53$^\circ$2790: the O9.5V counterpart to the X-ray binary system 4U~2206+54

description: The X-ray binary system 4U 2206+54 hides many mysteries. Among them, the surprising behavior of both of its components: the O9.5 dwarf star BD+53$^\circ$2790 and a slowly rotating neutron star. BD+53$^\circ$2790 misled the astronomers showing itself very likely as a Be star. However, a deeper spectral analysis and more intense monitoring, revealed that the real picture was a bit more complicated: a) Although it shows evidence of a circumstellar envelope, its observable properties differ from those typical envelopes in Be stars. b) Comparison with spectral standards and models indicates a possible over-abundance in He. This would open the possibility to link the behavior of BD+53$^\circ$2790 to the He-rich class of stars. c) UV spectra shows an abnormally slow and dense wind for an O9.5V star. d) Spectral classification in the IR wavelength region suggest a more likely supergiant nature of the source, in contradiction with the optical classification. e) The presence of an intense magnetic field is under investigation. BD+53$^\circ$2790 stands as a perfect laboratory for testing stellar structure, as well as wind and evolutionary theories. The observable properties of this source in a wide range of spectral bands are discussed, and some interpretations outlined.

description: Constrained Hamiltonian dynamics of a quantum system of nonlinear oscillators is used to provide the mathematical formulation of a coarse-grained description of the quantum system. It is seen that the evolution of the coarse-grained system preserves constant and minimal quantum fluctuations of the fundamental observables. This leads to the emergence of the corresponding classical system on a sufficiently large scale.
