description: The ``problem of time'' has been a pressing issue in quantum gravity for some time. To help understand this problem, Rovelli proposed a model of a two harmonic oscillators system where one of the oscillators can be thought of as a ``clock'' for the other oscillator thus giving a natural time reference frame for the system. Recently, the author has constructed an explicit form for the coherent states on the reduced phase space of this system in terms of Klauder's projection operator approach. In this paper, by using coherent state representations and other tools from coherent state quantization, I investigate the construction of gauge invariant operators on this reduced phase space, and the ability to use a quantum oscillator as a ``clock.''

description: What can we learn about the Intellectual history of the pre-modern Islamic world by examining the science of music? This dissertation addresses how the science of music, as a body of knowledge, was appropriated from its Greek origins, how this science was then reproduced and disseminated throughout Islamic civilization, and how Muslim society situated it vis-à-vis Islamic tradition. Widely considered to be an art today, music in the medieval Islamic world was categorized as one of the four branches of the mathematical sciences, alongside arithmetic, geometry, and astronomy; indeed, some philosophers and scholars of music went as far as linking music with medicine and astrology as part of an interconnected web of cosmological knowledge. This dissertation examines the epistemological tools and techniques that contributed to the production of musical knowledge from the early medieval to the early modern period (9th–17th centuries CE). This knowledge was often produced through the patronage of both the ruling and the urban elite classes. Furthermore, this dissertation demonstrates how this science was preserved and subsequently transmitted by scholars of the mathematical disciplines through manuscripts. By studying the marginalia and super commentaries of these manuscripts, it demonstrates how scholars in the Islamic world understood and engaged the tradition of the science of music.

description: Im Rahmen eines umfangreichen Forschungsprogramms über ebene Gitterströmungen wurden im Institut für Strömungsmechanik der T.H. Braunschweig für zwei Schaufelgitter mit stark gewölbten Profilen nach dem mit konformer Abbildung arbeitenden Traupelschen Verfahren für je fünf verschiedene Zuströmwinkel die potentialtheoretischen Druckverteilungen und die Abströmwinkel berechnet. Die Ergebnisse der Rechnung wurden mit Messungen an ebenen Gittern verglichen, wobei sich gute Ubereinstimmung ergab. Folgende Gitteranordnungen wurden untersucht:
Profil NACA 15.4.15 VN 10/20
Schaufelwinkel [beta]s = 60° [beta]s = 50°
Teilungsverhältnisse t/l = 0,75 t/l = 1,0
description: In the course of systematic investigations on two-dimensional cascade flow, which have been conducted at the Institute of Fluid Mechanics of the Engineering University of Braunschweig, pressure distributions and angles of outflow have been calculated for two turbine cascades with highly cambered blades, at five different angles of inflow each. The method used is that of conformal mapping due to W. Traupel. The theoretical results have been compared with experiments. Theoretical and experimental pressure distributions are in good agreement. For the angle of outflow the effect of viscosity is not negligible and, therefore, the agreement of theoretical and experimental results is not as good as for the pressure distributions.

description: In terms of a group-theoretical notation of crystal symmetry a simple scheme is derived and discussed which allows to classify any given tensor with regard to irreducible representations of the crystallographic groups.
To construct a complete decomposition-table for all 32 classes, a system of relating equations with universal constants has to be applied to a set of five numbers which sufficiently represent the specific properties (viz. order, intrinsic symmetry) of the tensor, and on which all results are dependent. Algebraic calculations with the representations are eliminated.
The five characteristic values Nz, namely the number of independent components under the influence of a z-fold axis (z=1;2;3;4;6), can be calculated by means of elementary methods or special formulas given in the paper.
Examples of third, fourth, sixth, & eighth order matter tensors illustrate the use of the scheme.

description: A macroscopic version of Einstein-Podolsky-Rosen entanglement is obtained by quenching a quadratic coupling between two O(N) vector models. A quench of the mixed vacuum produces an excited entangled state, reminiscent of purified thermal equilibrium, whose properties can be studied analytically in the free limit of the individual field theories. The decoupling of different wavelength modes in free field theory prevents true thermalisation but a more subtle difference is that the density operator obtained by a partial trace does not commute with the post-quench Hamiltonian. Generalized thermal behaviour is obtained at late times, in the limit of weak initial mixing or a smooth but rapid quench. More surprisingly, late-time correlation functions of composite operators in the post-quench free field theory share interesting properties with correlators in strongly coupled systems. We propose a holographic interpretation of our result.

Quality and Quantity of Language Input and Its Relation to the Language Outcomes of Preschool Children With Hearing Loss Who Use Listening and Spoken Language

description: This study sought to examine the relationships between the adult language input, as measured by quantity and quality, and the child’s language production in regards to quantity and quality, as well as their knowledge of basic concepts and vocabulary. LENA technology was used to audio-record the language environments of 26 preschool children with hearing loss over two days (weekday and weekend). This technology recorded up to 16 hours and analyzed the quantitative data associated with the adult word count (AWC), conversational turn count (CTC), and child vocalization count (CVC). Furthermore, one- hour meal times (30 minutes for the weekday/snack time and 30 minutes for the weekend/dinner time) was transcribed and coded for quality components of language defined as lexical diversity, syntactical complexity and clausal complexity. Additionally, the children were assessed on their knowledge of basic concepts through the Boehm Test of Basic Concepts (BTBC-3) and the Peabody Picture Vocabulary Test (PPVT-4).
      Results indicated that there was a relationship between the adult language input and the child language production, but only in regards to quantity of language. More specifically, the CTC during each day was related to the CVC for each day; in other words, the more interactions adults and children had during the day, the more likely the child vocalized. Interestingly, the statistical analysis revealed that quality of adult language input was not significantly related to the child language variables. However, significant differences between the teachers and caregivers were reported in regards to the quality of adult language input. These results suggest that the language input provided by adults in different environments (school versus home) is considerably different and warrants further investigation as how the potential influence on language outcomes of children with hearing loss.

description: We report scanning tunneling spectroscopy imaging of the vortex lattice in single crystalline MgB2. By tunneling parallel to the c-axis, a single superconducting gap (Delta = 2.2 meV) associated with the pi-band is observed. The vortices in the pi-band have a large core size compared to estimates based on Hc2, and show an absence of localized states in the core. Furthermore, superconductivity between the vortices is rapidly suppressed by an applied field. These results suggest that superconductivity in the pi-band is, at least partially, induced by the intrinsically superconducting sigma-band.

British Columbia, Canada's Crown Contaminated Sites Program : a 10-year review
Creators: name: Stewart, Gregg G. (Gregg Gordon), 1961-
Publisher: name: The University of British Columbia
Year: 2016

description: The Crown Contaminated Sites Program (CCSP) leads the management of contaminated publically owned lands in British Columbia, Canada. The program was initiated in 2003 and operates within the Ministry of Forests, Lands and Natural Resource Operations (FLNR) under a Cabinet-approved policy that commits CCSP to identify and prioritise contaminated sites that are a provincial responsibility. This policy uses a science-based risk assessment approach to protect human health and the environment. Although CCSP manages a wide range of contaminated sites, the vast majority of remediation effort has been directed at closing historic mine sites. This paper focuses on these mine sites and reviews the program’s inventory, assessment, prioritisation approach to site remediation. Over the past decade, a tremendous amount of progress has been made towards the CCSP’s goals. As the program matured, the focus shifted from developing various tools (e.g. site inventory, assessment guidance, risk-ranking methodology), to their implementation, and then to remediation and risk reduction. Since inception, the program has investigated 75 historic mine sites; eight have been fully remediated, and 15 are characterised as priority sites where ongoing assessment and remediation is occurring. Examples from these mine sites will be used to illustrate the program’s innovative and flexible approach. Of particular relevance to mine closure is that CCSP has demonstrated leadership in using a risk-based approach to assess and prioritise sites and protect human and ecological health. This approach improves the information available on contaminated sites through site research and a database of sites and activities related to them. Regular reports are made to government and the public on the progress of work and the financial burden of contaminated sites. The program works collaboratively with First Nations, communities, environmental organisations and other levels of government to tackle problems together. The end result after a decade of effort is a comprehensive and coordinated government-wide framework for managing contaminated sites on publically owned lands.

description: Der Stoffübergang aus einer Flüssigkeit in eine zweite angrenzende flüssige Phase erfolgt häufig nicht nur durch Diffusion, sondern schubweise durch "Eruptionen". Eine Vorbedingung für derartige Eruptionen ist, daß das in der Grenzfläche herrschende Gleichgewicht gestört wird, derart, daß benachbarten Flächenteilchen verschiedene GrenzfIächenspannungen aufgeprägt werden. Hierdurch werden heftige Bewegungen vorwiegend in tangentialer Richtung in der Grenzfläche hervorgerufen. Die Zähigkeitskräfte erzeugen beiderseits der Grenzfläche in den Flüssigkeiten turbulente Strömungen. In diesen treten statistisch verteilt Bewegungen und Schubspannungen auch senkrecht zur Grenzfläche auf. Diese sind die Ursache der beobachteten Erscheinungen. Es wird vorgeschlagen, derartige nicht im Gleichgewicht befindlichen Grenzflächen mit ihrer Umgebung als "aktive Grenzschichten" zu bezeichnen.
description: Mass transfer from one liquid into another adjacent liquid phase does not always occur by diffusion but in shoves by "eruptions". The first condition for such eruptions is that the equilibrium in the surface between the phases is disturbed, i.e. adjacent areas of the surface have different surface tensions. Hereby a violent movement, mainly in tangential direction, is induced in the surface between the phases. By viscosity forces turbulent currents are created in the liquids at both sides of this surface. In these currents, statistically distributed movements and shearing strains occur, also vertical to the limiting surface. These are responsible for the observed results. It is proposed to call such limiting surfaces with disturbed equilibrium and the surrounding layers "active boundary layers".

description: Smooth surfaces have finitely generated canonical rings and projective canonical models. For normal surfaces, however, the graded ring of multicanonical sections is possibly nonnoetherian, such that the corresponding homogeneous spectrum is noncompact. I construct a canonical compactification by adding finitely many non-Q-Gorenstein points at infinity, provided that each Weil divisor is numerically equivalent to a Q-Cartier divisor. Similar results hold for arbitrary Weil divisors instead of the canonical class.

description: We study the ionopause of Mars using a database of 6,893 ionopause detections obtained over 11 years by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) experiment. The ionopause, in this work, is defined as a steep density gradient that appears in MARSIS remote sounding ionograms as a horizontal line at frequencies below 0.4 MHz. We find that the ionopause is located on average at an altitude of $363 \pm 65$ km. We also find that the ionopause altitude has a weak dependence on solar zenith angle and varies with the solar extreme ultraviolet (EUV) flux on annual and solar cycle time scales. Furthermore, our results show that very few ionopauses are observed when the crustal field strength at 400 km is greater than 40 nT. The strong crustal fields act as mini-magnetospheres that alter the solar wind interaction and prevent the ionopause from forming.

description: These lecture notes are based on a tutorial given in 2017 at a plasma physics winter school in Les Houches. Their aim is to provide a self-contained graduate-student level introduction to the theory and modelling of the dynamo effect in turbulent fluids and plasmas, blended with a review of current research in the field. The primary focus is on the physical and mathematical concepts underlying different (turbulent) branches of dynamo theory, with some astrophysical, geophysical and experimental context disseminated throughout the document. The text begins with an introduction to the rationale, observational and historical roots of the subject, and to the basic concepts of magnetohydrodynamics relevant to dynamo theory. The next two sections discuss the fundamental phenomenological and mathematical aspects of (linear and nonlinear) small- and large-scale MHD dynamos. These sections are complemented by an overview of a selection of current active research topics in the field, including the numerical modelling of the geo- and solar dynamos, shear dynamos driven by turbulence with zero net helicity, and MHD-instability-driven dynamos such as the magnetorotational dynamo. The difficult problem of a unified, self-consistent statistical treatment of small and large-scale dynamos at large magnetic Reynolds numbers is also discussed throughout the text. Finally, an excursion is made into the relatively new but increasingly popular realm of magnetic-field generation in weakly-collisional plasmas. A short discussion of the outlook and challenges for the future of the field concludes the presentation.

description: While sickle cell disease (SCD) primarily affects those of African heritage, Latinos, the second most commonly affected group, are often not included in studies of youth with SCD. The purpose of this mixed methods study was to complete the linguistic translation validation of the PedsQL SCD Module, a recently validated disease specific quality of life (QOL) instrument, for use in Spanish speaking parents and youth with SCD (Aim 1). Using this instrument, QOL of Latino and African American youth with SCD who participated in an NIH funded study to improve adherence to hydroxyurea therapy (R21 NR013745) were compared (Aim 2) and factors associated with QOL examined (Aim 3). For Aim 1, 10 Latino youth with SCD (n = 5 age, 8-12 years; n = 5 age, 13-18 years) and their parents completed a demographic survey, Spanish version of PedsQL SCD Module and an audio-taped cognitive interview. Across age groups, all reported that the translated PedsQL Sickle Cell Disease Module was easy to understand and had minimal suggestions for further improvement. For Aims 2 and 3, secondary baseline data from 28 youth (mean age 13.6  2.4 years) with sickle cell disease and their parents who participated in the HABIT feasibility trial were analyzed using descriptive statistics, Wilcoxon Signed Rank and Mann-Whitney test, and linear regression modeling. Latino youth reported higher QOL scores than non-Latino youth for all QOL measures except for the Worry II subscale of the disease-specific QOL measure while Latino parents reported higher QOL scores than non-Latino parents for all subscales except for three: the disease-specific Worry I, Worry II, and Communication I subscales. Poorer disease specific QOL was predicted by greater youth-parent discordance regarding sickle cell disease responsibility for parents (β = -3.07, p = 0.04) but not youth. Poorer disease-specific QOL was predicted by greater number of both emergency room visits during the prior year for both youth (β = -2.89, p = 0.005 [self-report]; β = -5.07, p = 0.002 [electronic medical records]) and parents (β = -3.41, p = 0.002 [self-report]; β = -6.93, p = <0.001 [electronic medical records]) and hospitalizations during the prior year (youth β = -5.72, p = <0.001 [self-report]; β = -7.56, p = 0.03 [electronic medical records]; parents β = -6.48, p = <0.001 [self-report];
      β = -9.16, p = 0.02 [electronic medical record]). Based on these findings, greater youth-parent discordance regarding sickle cell family responsibility and greater utilization of emergency rooms and/or hospitals were associated with poorer disease-specific QOL.

description: The chiral anomaly is a phenomenon characteristic of Weyl fermions, which has condensed matter realizations in Weyl semimetals. Efforts to observe smoking gun signatures of the chiral anomaly in Weyl semimetals have mostly focused on a negative longitudinal magnetoresistance in electronic transport. Unfortunately, disentangling the chiral anomaly contribution in transport or optical measurements has proven non-trivial. Recent works have proposed an alternative approach of probing pseudoscalar phonon dynamics for signatures of the chiral anomaly in non-mirror-symmetric crystals. Here, we show that such phonon signatures can be extended to scalar phonon modes and mirror-symmetric crystals, broadening the pool of candidate materials. We show that the presence of the background magnetic field can break mirror symmetry strongly enough to yield observable signatures of the chiral anomaly even in mirror-symmetric materials. Specifically for mirror-symmetric Weyl semimetals such as TaAs and NbAs, including the Zeeman interaction at $B \approx 10$T, we predict an IR reflectivity peak will develop with an $\mathbf{E}_\text{IR}\cdot\mathbf{B}$ dependence.

description: Olmesartan medoxomil (OM) is a hydrophobic antihypertensive drug with low bioavailability (26%) and is known to have adverse effects such as celiac disease and enteropathy. The purpose of this study was to develop SMEDDS to increase bioavailability and decrease potential side effects of OM. Hydrophilic lipophilic balance was calculated by testing solubility of OM in different oils, surfactants, and cosurfactants to obtain the most suitable combination of SMEDDS. Pseudoternary phase diagram was used to select the better oil/water formulation of SMEDDS. After a test for 3-month stability, dissolution tests and parallel artificial membrane permeability assay (PAMPA) were conducted to investigate drug solubility and permeability. Biodistribution of fluorescent marked SMEDDS was observed by using in vivo imaging system. The pharmacodynamics of the drug were determined by measuring blood pressure from tails of rats. At the end of the experiment, intestines were examined for adverse effects of OM. Compared with tablet formulation according to the dissolution study, SMEDDS formulation showed 1.67 times improvement in solubility of OM. PAMPA studies suggested a much faster permeability rate for OM SMEDDS compared to the suspension form. Labeled SMEDDS gave 3.96 times stronger fluorescent emission than control dye administered mice in in vivo imaging system (IVIS®) studies, indicating an increased bioavailability. Treating effect of SMEDDS was 3.1 times more efficient compared to suspension in hypertensive rats. It caused neither celiac-like enteropathy nor diarrhea, during 21-day noninvasive blood pressure system (NIBP) assay. Our results suggest that SMEEDS formulation improves dissolution and oral bioavailability of OM while reducing its adverse effects.
Homology TQFT's and the Alexander-Reidemeister Invariant of 3-Manifolds via Hopf Algebras and Skein Theory

description: We develop an explicit skein theoretical algorithm to compute the Alexander polynomial of a 3-manifold from a surgery presentation employing the methods used in the construction of quantum invariants of 3-manifolds. As a prerequisite we establish and prove a rather unexpected equivalence between the topological quantum field theory constructed by Frohman and Nicas using the intersection homology of U(1)-representation varieties on the one side and the combinatorially constructed Hennings-TQFT based on the quasitriangular Hopf algebra ${\cal N}=\Z/2\ltimes \ext *\R^2$ on the other side. We find that both TQFT's are $SL(2,\R)$-equivariant functors and also as such isomorphic. The $SL(2,\R)$-action in the Hennings construction comes from the natural action on $\cal N$ and in the case of the Frohman-Nicas theory from the Hard-Lefschetz decomposition of the U(1)-moduli spaces given that they are naturally Kähler. The irreducible components of this TQFT, corresponding to simple representations of $SL(2,\Z)$ and $Sp(2g,\Z)$, thus yield a large family of homological TQFT's by taking sums and products. We give several examples of TQFT's and invariants that appear to fit into this family, such as Milnor and Reidemeister Torsion, Seiberg-Witten theories, Casson type theories for homology circles á la Donaldson, higher rank gauge theories following Frohman and Nicas, and the $\Z/r$ reductions of Reshetikhin-Turaev theories over the cyclotomic integers $\Z[ζ_r]$. We also conjecture that the Hennings TQFT for quantum-${\mathfrak sl}_2$ is the product of the Reshetikhin-Turaev TQFT and such a homological TQFT.

description: In this paper we extend the concept of separatrix reconnection into chaotic regimes. We show that even under chaotic conditions one can still understand abrupt jumps of diffusive-like processes in the relevant phase-space in terms of relatively smooth realignments of stable and unstable manifolds of unstable fixed points.

description: A gauge invariant Hamiltonian representation for SU(2) in terms of a spin network basis is introduced. The vectors of the spin network basis are independent and the electric part of the Hamiltonian is diagonal in this representation. The corresponding path integral for SU(2) lattice gauge theory is expressed as a sum over colored surfaces, i.e. only involving the $j_p$ attached to the lattice plaquettes. This surfaces may be interpreted as the world sheets of the spin networks In 2+1 dimensions, this can be accomplished by working in a lattice dual to a tetrahedral lattice constructed on a face centered cubic Bravais lattice. On such a lattice, the integral of gauge variables over boundaries or singular lines -- which now always bound three coloured surfaces -- only contributes when four singular lines intersect at one vertex and can be explicitly computed producing a 6-j or Racah symbol. We performed a strong coupling expansion for the free energy. The convergence of the series expansions is quite different from the series expansions which were performed in ordinary cubic lattices. In the case of ordinary cubic lattices the strong coupling expansions up to the considered truncation number of plaquettes have the great majority of their coefficients positive, while in our case we have almost equal number of contributions with both signs. Finally, it is discused the connection in the naive coupling limit between this action and that of the B-F topological field theory and also with the pure gravity action.

description: Since the introduction of factory outlet center, the Yansha Outlet, to China in 2012, over five hundred retail centers have been constructed under the name of "outlet". As a new format of retailing and due to the "over-construction" of it, factory outlet has caught large attention of developers, consumers as well as professionals. Based on previous research, this thesis examines the macro factors, including government regulations and transportation and micro factors, including institutional characteristics that may influence the development and performance of factory outlet center. The thesis analyzes four outlet shopping centers in Beijing and collects data through government documentation, second hand data, interview, site visit and survey. The analysis shows that government regulation and planning, driving convenience, discounts and other factors have large effects on the development and performance of factory outlet center. Finally, suggestions are given from planners' perspective.
Chaos and Energy Redistribution the Nonlinear Interaction of Two Spatio-Temporal Wave Triplets

description: In this paper we examine the spatio-temporal dynamics of two nonlinearly coupled wave triplets sharing two common modes. Our basic findings are the following. When spatial dependence is absent, the homogeneous manifold so obtained can be chaotic or regular. If chaotic, it drives energy diffusion from long to small wavelengths as soon as inhomogeneous perturbations are added to the system. If regular, one may yet have two distinct cases: (i) energy diffusion is again present if the inhomogeneous modes are linearly unstable and triplets are effectively coupled; (ii) energy diffusion is absent if the inhomogeneous modes are linearly stable or the triplets are uncoupled.

Quality of care during childbirth in low-resource settings: Applying an epidemiology lens to an implementation problem

description: While significant progress has been made towards improving health outcomes in low-resource settings, unacceptably high maternal mortality remains a problem. Efforts to improve maternal mortality in low-resource settings did not yield intended results. One hypothesized reason for insufficient maternal mortality progress is poor interpersonal quality of care during childbirth at health facilities. Qualitative studies support the assumptions of quality of care frameworks that connect structural inputs (e.g. drugs and supplies, equipment, human resources) to interpersonal quality. However, there is no quantitative evidence for this relationship. Further, although maternal health researchers developed quantitative tools to measure interpersonal quality of care, the construct is mainly operationalized as a single, bipolar dimension, measured as respectful maternity care (good care) or disrespect and abuse (poor care). To address these limitations, this dissertation used an epidemiologic perspective to test the underlying assumptions of quality of care frameworks and to create a robust measure of interpersonal quality of care. This dissertation consists of three parts: an empirical study to test the hypothesis that structural inputs have a positive effect on interpersonal quality of care; a systematic review of the literature of instruments measuring the construct of interpersonal quality of care and their reliability, validity, and dimensionality; and an empirical study to assess the dimensionality and construct validity of the Maternal Health Interpersonal Quality Scale, a measure of interpersonal quality of care.
      The first empirical study did not find meaningful associations between HIV structural inputs and maternal health structural inputs and interpersonal quality of care during childbirth. These results do not support the assumptions of quality of care frameworks nor qualitative evidence linking structural inputs and interpersonal quality of care. The systematic review suggested that the construct of interpersonal quality of care is not well-defined, that few instruments met psychometric standards for adequate reliability and validity, and that studies that assessed the instruments were generally of poor quality. The second empirical study found that interpersonal quality of care formed a two-dimensional, correlated structure, with one dimension measuring respectful maternity care and one dimension measuring disrespect and abuse. Overall, this dissertation used an epidemiologic lens to address an implementation problem in maternal health. While there is a need to improve interpersonal quality of care during childbirth, in order to impact change and to avoid implementation failure, it is imperative to ensure interventions have a strong evidence base and to use validated measures of the construct.
