Publisher: name: arXiv
Year: 1996
Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: The defining conditions for the irreducible tensor operators associated with the unitary irreducible corepresentions of compact quantum group algebras are deduced first in both the right and left regular coaction formalisms. In each case it is shown that there are {\em{two}} types of irreducible tensor operator, which may be called `ordinary' and `twisted'. The consistency of the definitions is demonstrated, and various consequences are deduced, including generalizations of the Wigner-Eckart theorem for both the ordinary and twisted operators. Also included are discussions (within the regular coaction formalisms for compact quantum group algebras) of inner-products, basis functions, projection operators, Clebsch-Gordan coefficients, and two types of tensor product of corepresentations. The formulation of quantum homogeneous spaces for compact quantum group algebras is discussed, and the defining conditions for the irreducible tensor operators associated with such quan! tum homogeneous spaces and with the unitary irreducible corepresentions of the compact quantum group algebras are then deduced. There are two versions, which correspond to restrictions of the right and left regular coactions. In each case it is again shown that there are ordinary and twisted irreducible tensor operators. Various consequences are deduced, including the corresponding generalizations of the Wigner-Eckart theorem.

description: In the era of precision cosmology, it is essential to empirically determine the Hubble constant with an accuracy of one per cent or better. At present, the uncertainty on this constant is dominated by the uncertainty in the calibration of the Cepheid period - luminosity relationship (also known as Leavitt Law). The Large Magellanic Cloud has traditionally served as the best galaxy with which to calibrate Cepheid period-luminosity relations, and as a result has become the best anchor point for the cosmic distance scale. Eclipsing binary systems composed of late-type stars offer the most precise and accurate way to measure the distance to the Large Magellanic Cloud. Currently the limit of the precision attainable with this technique is about two per cent, and is set by the precision of the existing calibrations of the surface brightness - colour relation. Here we report the calibration of the surface brightness-colour relation with a precision of 0.8 per cent. We use this calibration to determine the geometrical distance to the Large Magellanic Cloud that is precise to 1 per cent based on 20 eclipsing binary systems. The final distane is 49.59 +/- 0.09 (statistical) +/- 0.54 (systematic) kiloparsecs.

description: A liquid crystal (LC) with negative dielectric anisotropy called N-(4-Methoxybenzylidene)-4-Butylaniline (MBBA) doped with the ionic agent cetyltrimethylammonium bromide (CTAB) has been investigated as a speckle suppression device to reduce the laser’s speckle contrast. The electrohydrodynamic instabilities (EHDI) effect in LC is exploited to reduce speckle contrast. The EHDI effect causes chaotic turbulence in LC, resulting in dynamic scattering of the incident light beam. In order to investigate the electro-optic properties and frequency region for optimal performance, optical measurements and dielectric spectroscopy of the pristine and doped LC are performed. The dielectric characteristics of the LC demonstrate that the frequency range to produce the EHDI effect in the LC cell is broadened as the ionic agent is doped. The inclusion of ions also enhances the ion density, mobility, and conductivity in LC. The increase in ion density and mobility enhances the turbulence in the LC at a faster rate; as a result, the dynamic scattering becomes more rapid. When measured with a charge-coupled device (CCD) camera, the faster dynamic scattering provides higher suppression in the laser’s speckle contrast. This method can be used to reduce the speckle contrast in laser source-based imaging and projection displays.

description: Many neuronal patterning genes are expressed in distinct populations of cells in the nervous system, leading researchers to analyze their function in specific isolated cellular contexts that often obscure broader, themes of gene function. In this thesis, I aim to make clearer those overlooked common functional themes. I show that the C. elegans homeobox gene unc-42 is expressed in 15 out of a total of 118 distinct sensory, inter, and motor neuron classes throughout the C. elegans nervous system. Of these 15 unc-42(+) synaptically interconnected neuron classes, I show the extent to which unc-42 controls their identities and assembly into functional circuitry. I find that unc-42 defines the routes of communication between these interconnected neurons by controlling the expression of neurotransmitter pathway genes, neurotransmitter receptors, neuropeptides and neuropeptide receptors. I also show that unc-42 controls the expression of molecules involved in axon pathfinding and cell-cell recognition. Consequently, I show how the loss of unc-42 has effects on axon pathfinding and chemical synaptic connectivity, as determined by electron microscopical reconstruction of serial sections of unc-42 mutants. I conclude that unc-42 plays a critical role in establishing functional circuitry by acting as a terminal selector of functionally connected neuron types. I speculate that in other parts of the nervous system “circuit transcription factors” may also control assembly of functional circuitry and propose that such organizational properties of transcription factors may be reflective of not only an ontogenetic, but perhaps also phylogenetic trajectory of neuronal circuit establishment.

description: KCFLC 7S, a ferroelectric liquid crystal (FLC) shows improved dielectric and electro-optic properties by the incorporation of alloyed quaternary ZnCuGaS2/ZnS core/shell (ZCZ) quantum dots (QDs). Four different Zn alloyed ZCZ QDs (ZCZ-0, ZCZ-0.5, ZCZ-1, and ZCZ-1.5) incorporated in FLC and have been studied with the help of optical, dielectric and ferroelectric characterisations. Substantial changes of optical contrast, molecular ordering, photoluminescence, dielectric constant, dielectric loss factor, response time, and helical pitch of FLC are observed and attributed to varying molecular ordering. The effective confinement of exciton wavefunction in core of QDs results in improved molecular ordering of FLC material. The Zn alloyed ZCZ QDs incorporated FLC may be resulted for future brighter, high contrast, large viewing angle and memory based display device.

description: We study quantum metrology for unitary dynamics. Analytic solutions are given for both the optimal unitary state preparation starting from an arbitrary mixed state and the corresponding optimal measurement precision. This represents a rigorous generalization of known results for optimal initial states and upper bounds on measurement precision which can only be saturated if pure states are available. In particular, we provide a generalization to mixed states of an upper bound on measurement precision for time-dependent Hamiltonians that can be saturated with optimal Hamiltonian control. These results make precise and reveal the full potential of mixed states for quantum metrology.

description: We study the transverse dynamical spin susceptibility of the two dimensional U(1) spinon Fermi surface spin liquid in a small applied Zeeman field. We show that both short-range interactions, present in a generic Fermi liquid, as well as gauge fluctuations, characteristic of the U(1) spin liquid, qualitatively change the result based on the frequently assumed non-interacting spinon approximation. Short-range interaction leads to a new collective mode: a "spinon spin wave" which splits off from the two-spinon continuum at small momentum and disperses downward. Gauge fluctuations renormalize the susceptibility, providing non-zero power law weight in the region outside the spinon continuum and giving the spin wave a finite lifetime, which scales as momentum squared. We also study the effect of Dzyaloshinskii-Moriya anisotropy on the zero momentum susceptibility, which is measured in electron spin resonance (ESR), and obtain a resonance linewidth linear in temperature and varying as $B^{2/3}$ with magnetic field $B$ at low temperature. Our results form the basis for a theory of inelastic neutrons scattering, ESR, and resonant inelastic x-ray scattering (RIXS) studies of this quantum spin liquid state.

description: Fluorescent liquid crystalline compounds have been the focal point of research due to their rich applications in organic optoelectronics. Fluorescent dyes have also found great applications in the development of random lasers and non-linear optics. Other than that, materials with high fluorescence intensity and quantum yield have been very desirable for various electro-optical applications over the years. We have attempted to engineer a highly fluorescent nematic liquid crystalline compound (4′-pentyl-4-biphenylcarbonitrile/5CB) with high quantum yield by doping anthracene dye. We have obtained the desired increase in fluorescence intensity due to anthracene being fluorescent as well and a further significantly high quantum yield for higher concentrations of anthracene in the nematic compound. The reduction in non-emissive radiations and the increase in the concentration of fluorophores in the excited state can be held responsible for this increased quantum yield. Lifetime of the fluorophores has been found to increase with the increase in the dye concentration. The obtained results make the anthracene-doped 5CB compound highly desirable for various device applications.

description: Color vision is widespread in the animal kingdom, and describes the ability to discriminate between objects purely based on the wavelengths that they reflect. Experiments across many species have isolated wavelength comparison in the brain as a computation underlying color vision. This comparison takes place in color opponent neurons, which respond with opposite polarity to wavelengths in different parts of the spectrum. In this work, I explore color opponency in the genetically tractable organism Drosophila melanogaster, where these circuits have only just begun to be described. Using two-photon calcium imaging, I measure the spectral tuning of photoreceptors in the fruit fly and identify circuit mechanisms that give rise to opponency. I find two pathways: an insect-specific pathway that compares wavelengths at each point in space, and a horizontal-cell-mediated pathway similar to that found in mammals. The horizontal-cell-mediated pathway enables additional spectral comparisons through lateral inhibition, expanding the range of chromatic encoding in the fly. Together, these two pathways enable efficient decorrelation and dimensionality reduction of photoreceptor signals while retaining maximal chromatic information. This dual mechanism combines motifs of both an insect-specific visual circuit and an evolutionarily convergent circuit architecture, endowing flies with the ability to extract chromatic information at distinct spatial resolutions.

description: SWIFT J1658.2-4242 is an X-ray transient discovered recently in the Galactic plane, with severe X-ray absorption corresponding to an equivalent hydrogen column density of $N_{\rm H,abs}\sim2\times10^{23}$ cm$^{-2}$. Using new Chandra and XMM-Newton data, we discover a strong X-ray dust scattering halo around it. The halo profile can be well fitted by the scattering from at least three separated dust layers. During the persistent emission phase of SWIFT J1658.2-4242, the best-fit dust scattering $N_{\rm H,sca}$ based on the COMP-AC-S dust grain model is consistent with $N_{\rm H,abs}$. The best-fit halo models show that 85-90 percent of the intervening gas and dust along the line of sight of SWIFT J1658.2-4242 are located in the foreground ISM in the Galactic disk. The dust scattering halo also shows significant azimuthal asymmetry, which appears consistent with the inhomogeneous distribution of foreground molecular clouds. By matching the different dust layers to the distribution of molecular clouds along the line of sight, we estimate the source distance to be $\sim$10 kpc, which is also consistent with the results given by several other independent methods of distance estimation. The dust scattering opacity and the existence of a halo can introduce a significant spectral bias, the level of which depends on the shape of the instrumental point spread function and the source extraction region. We create the Xspec dscor model to correct for this spectral bias for different X-ray instruments. Our study reenforces the importance of considering the spectral effects of dust scattering in other absorbed X-ray sources.

description: Hyperspectral super-resolution (HSR) is a problem that aims to estimate an image of high spectral and spatial resolutions from a pair of co-registered multispectral (MS) and hyperspectral (HS) images, which have coarser spectral and spatial resolutions, respectively. In this paper we pursue a low-rank matrix estimation approach for HSR. We assume that the spectral-spatial matrices associated with the whole image and the local areas of the image have low-rank structures. The local low-rank assumption, in particular, has the aim of providing a more flexible model for accounting for local variation effects due to endmember variability. We formulate the HSR problem as a global-local rank-regularized least-squares problem. By leveraging on the recent advances in non-convex large-scale optimization, namely, the smooth Schatten-p approximation and the accelerated majorization-minimization method, we develop an efficient algorithm for the global-local low-rank problem. Numerical experiments on synthetic, semi-real and real data show that the proposed algorithm outperforms a number of benchmark algorithms in terms of recovery performance.

description: “Circulating Knowledges: Literature and the Idea of the Library in Renaissance England” pairs literary texts and libraries to illustrate how literary creation and library building in England from 1500 to 1700 were deeply invested in one another. The history of English Renaissance libraries has generally been analyzed from the viewpoints of religious history and historiography, seen by scholars as a story of Protestant librarians attempting to preserve (or invent) a history of Protestant England. Many literary critics —citing Thomas Bodley’s notorious distaste for “stage plaies”—have typically reduced institutional libraries to elitist boogeymen hostile to popular or vernacular literature. Revising these narratives, this dissertation brings together a large corpus, including works by Thomas More, John Lyly, Edmund Spenser, Robert Greene, Christopher Marlowe, Francis Bacon, and Margaret Cavendish, to illustrate how literary depictions of England’s fledgling libraries shaped their creation and development, while the practices of these inchoate libraries in turn influenced literary texts. “Circulating Knowledges” advances its argument on several fronts. First, I show that developments (or a perceived lack of development) in library organization, access, and use appeared in literary texts, which often depicted literary libraries in response to these developments. Second, I home in on moments when literary texts that seem not at all interested in libraries become unexpectedly fruitful texts through which to develop literary thinking about libraries. In the process of excavating this literary interest in libraries, I demonstrate that Renaissance literature concerns itself not only with depicting, commenting on, or objecting to the developments in library creation happening during the period, but also in imagining alternative possibilities for how libraries might function, conceptions of a library that often outstripped what was materially possible in the period: these conceptions I term “the idea of the library.” In detailing literature’s preoccupation with developments in Renaissance library systems, I offer new perspectives on the period’s literary attitudes toward the creation, transmission, and protection of knowledge, all questions which the building—or imagining—of a library brings to the forefront.

description: Although revealing the spatial-temporal characteristics of soil microbial community is a core goal in microbial ecology, the unavailability of fresh soil samples or cryopreserved soil samples greatly limits our understanding of changes in the structure and function of the soil microbial community. Archived soils, from soil research institutions or soil museums, make it possible to delineate microbial community dynamics from the 1840s up to now. However, almost all studies on the microbial community structure in archived soils either focused solely on the microbial community of historical soils or simply compared modern soils with historical soils. The discernment capacity of the archived soils in relation to microbial community variation was confirmed only among fertilization treatments, soil types, and geographical distance. Thus, it has not been possible to distinguish the effects of long-term environmental changes and human activities (what we want to know) during the air-drying and archiving process (what we usually ignore). This limits the use of archived soils from field experiments to examine the long-term effects of environmental parameters on soil microbial community. The main objectives of this study were to (1) investigate the microbial community dynamics during air-drying and archiving process, using soils under long-term different fertilization treatments (Chapter 2), and from different geographical locations (Chapter 4); (2) characterize the microbial community in both fresh and long-term archived soil profile samples under common conditions in microbial ecology study (Chapter 3); and (3) assess the potential of retrieving the soil microbial community from the air-dried and archived soils.

description: The spontaneous generation of magnetic and chromomagnetic fields at high temperature in the minimal supersymmetric standard model (MSSM) is investigated. The consistent effective potential including the one-loop and the daisy diagrams of all bosons and fermions is calculated and the magnetization of the vacuum is observed. The mixing of the generated fields due to the quark and s-quark loop diagrams and the role of superpartners are studied in detail. It is found that the contribution of these diagrams increases the magnetic and chromomagnetic field strengths as compared with the case of a separate generation of fields. The magnetized vacuum state is found to be stable due to the magnetic masses of gauge fields included in the daisy diagrams. Applications of the results obtained are discussed. A comparison with the standard model case is done.

description: Abstract. In this report a new backward strictness analysis for functional languages is presented. It is called higher order demand propagation and is applicable to a realistic non-strict functional language, which has a polymorphic type system and supports higher order functions and user definable algebraic data types. This report defines a semantics for higher order demand propagation and relates it to the standard semantics of the functional language. Each definition in a program is mapped to a demand propagator, which is a higher order function, that propagates context demands to function arguments. The strictness information deduced by the analysis is very accurate, because demands can actually be constructed during the analysis. These demands conform better to the analysed functions than abstract values, which are constructed alone with respect to the type information like in other existing strictness analyses. The richness of the semantic domains of higher order demand propagation makes it possible to express generalised strictness information for higher order functions even across module boundaries. An approach to integrate the higher order demand propagation analysis into an existing compiler for a lazy functional language is sketched at the end of the report.

title: Amalgamation, Organising and Centralisation: A Study of Three Australian Unions
Creators: name: Martin, John Robert

Subjects: subject: Centralised functions in Australian workers unions

description: The research question discussed below was prompted by an observation of some, but by no means all, Australian unions seeking to centralise a number of functions in their federal office. Several countervailing factors impact upon the propensity of unions to centralise functions, which leads to some secondary research questions. The primary research question that this thesis seeks to answer is what has given rise to the centralisation of functions within three Australian unions? The question is asked in the context of declining union membership in Australia and most other developed economies (Bodman 1998; Dabscheck 1995; Jerrard and Le Queux 2013; Peetz 1998; Sappey et al 2006; Watson et al 2003). The decline in union membership is of concern to many industrial relations scholars (Boyer 1995; Bramble 1995; Bramble 2001; Conrow and Delp 1999; Cooper 2001; Hyman 2004; Juravich and Bronfenbrenner 1998:281; Peetz 1998:175; Peetz, Pocock and Houghton 2007; Simms and Holgate 2008; Voss and Sherman 2000:311; Wooden 2000) and is quite obviously of significant concern to the labour movement (ACTU 2001). It is for this reason that the question is significant, whether the centralisation of functions and powers is of assistance, or is counter-productive to other union renewal strategies. Arising out of the Primary Research Question, there are a range of secondary questions.

description: We analyze statistical properties of complex eigenvalues of random matrices $\hat{A}$ close to unitary. Such matrices appear naturally when considering quantized chaotic maps within a general theory of open linear stationary systems with discrete time. Deviation from unitarity are characterized by rank $M$ and eigenvalues $T_i, i=1,...,M$ of the matrix $\hat{T}=\hat{\bf 1}-\hat{A}^{\dagger}\hat{A}$. For the case M=1 we solve the problem completely by deriving the joint probability density of eigenvalues and calculating all $n-$ point correlation functions. For a general case we present the correlation function of secular determinants.

Citizen Science in the Classroom: Assessing the Impact of an Urban Field Ecology Program on Learning Gains and Attitudes toward Science
Creators: Collins, Andrew
Publisher: name: Columbia University

Subjects: Science--Study and teaching
Middle school education

description: This study examines the educational impact of a citizen-science based teaching unit in the formal classroom setting. Citizen science has traditionally involved amateur scientists and adult volunteers, however, an increasing number of projects are focusing on student participants and K-12 education. A six-week curriculum intervention based on a citizen-science project studying ant diversity in urban areas was implemented in a New York City middle school science classroom. Quantitative analysis of students’ pre- and post-assessments indicate significant learning gains as compared to a similar reference group that did not receive the intervention. Students in the treatment group showed a 22% greater increase in content knowledge from pre- to post- assessments. Qualitative analysis of these assessments along with interview responses show a positive change in students’ perceptions and attitudes toward science as well as an increased desire to contribute to ongoing research. Students expressed increased confidence in their ability to contribute to scientific research after participating in this educational program. The results from this study provide an analysis of the effectiveness of citizen-science based curriculum units and support their use in the formal classroom setting.
Cities on the Edge: Significance and Preservation of Hillside Squatter Settlements in Korea

Historic preservation

description: Hillside squatter settlements in Seoul and other major cities in Korea were formed on the mountains and hillsides as a result of an exponential population growth during the rapid urbanization after the Korean War. A large number of refugees and urban migrants were displaced from urban centers and relocated to the outskirts of cities, as modernization and urban development expanded outward from the city centers in the 1960s and 70s. Commonly known as Dal-dong-ne’s, these settlements were stigmatized as blighted areas with substandard housing conditions and low-income households. Within the past few decades, these areas have been eradicated by urban renewal and have been replaced with clusters of high-rise apartment buildings. The intimate scale and intricate networks of streets of these towns are the foundation for the strong sense of community that is characteristic of these settlements. Therefore, the destruction of these areas not only erases a significant fragment of South Korea’s historic urban landscape, but also weakens the socio-cultural identity of these neighborhoods. Recognizing these issues, there have been recent movements to rejuvenate these neighborhoods, while maintaining the existing fabric of the towns. This thesis will first analyze the significance of the physical townscape of the hillside squatter settlements, then identify the role of preservation in the future development schemes that strive to save the existing structures, as the foundation for reclaiming a sense of community. It is my belief that integrating preservation measures into sustainable town-regeneration plans will improve and protect physical resources, strengthen positive aspects of local identity, as well as provide social benefits for marginalized communities. For the sustainable management of historic resources and for the sustainable future of preservation practice itself, preservationists should proactively engage in the process of heritage work to help people enhance their quality of life.
Dual Isomonodromic Problems and Whitham Equations

description: The author's recent results on an asymptotic description of the Schlesinger equation are generalized to the JMMS equation. As in the case of the Schlesinger equation, the JMMS equation is reformulated to include a small parameter $ε$. By the method of multiscale analysis, the isomonodromic problem is approximated by slow modulations of an isospectral problem. A modulation equation of this slow dynamics is proposed, and shown to possess a number of properties similar to the Seiberg- Witten solutions of low energy supersymmetric gauge theories.

description: We study the confinement between vortex strings in the dual lattice gauge theory of the abelian Higgs model. The dual lattice gauge theory is described by a 2-form gauge field. We calculate the string-antistring potential from the surface operator of the 2-form gauge field. The linear confining potential appears in a confinement phase and it disappears in a deconfinement phase. The phase diagram of the theory is also obtained.

Double deeply virtual Compton scattering off the nucleon

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the double deeply virtual Compton scattering (DDVCS) process off the nucleon, through the scattering of a spacelike virtual photon with large virtuality resulting in the production of a timelike virtual photon, decaying into an e^+ e^- pair. This process is expressed in the Bjorken regime in terms of generalized parton distributions (GPDs) and it is shown that by varying the invariant mass of the lepton pair, one can directly extract the GPDs from the observables. We give predictions for the DDVCS cross section and beam helicity asymmetry and discuss its experimental feasibility.

Quench induced vortex-bright-soliton formation in binary Bose-Einstein condensates

description: We unravel the spontaneous generation of vortex-bright-soliton structures in binary Bose-Einstein condensates with a small mass imbalance between the species confined in a two-dimensional harmonic trap where one of the two species has been segmented into two parts by a potential barrier. To trigger the dynamics the potential barrier is suddenly removed and subsequently the segments perform a counterflow dynamics. We consider a relative phase difference of $π$ between the segments, while a singly quantized vortex may be imprinted at the center of the other species. The number of vortex structures developed within the segmented species following the merging of its segments is found to depend on the presence of an initial vortex on the other species. In particular, a $π$ phase difference in the segmented species and a vortex in the other species result in a single vortex-bright-soliton structure. However, when the non-segmented species does not contain a vortex the counterflow dynamics of the segmented species gives rise to a vortex dipole in it accompanied by two bright solitary waves arising in the non-segmented species. Turning to strongly mass imbalanced mixtures, with a heavier segmented species, we find that the same overall dynamics takes place, while the quench-induced nonlinear excitations become more robust. Inspecting the dynamics of the angular momentum we show that it can be transferred from one species to the other, and its transfer rate can be tuned by the strength of the interspecies interactions and the mass of the atomic species.

Concurrency Annotations and Reusability

description: Widespread acceptance of concurrent object-oriented programming in the field can only be expected if smooth integration with sequential programming is achieved. This means that a common language base has to be used, where the concurrent syntax differs as little as possible from the sequential one but is associated with a "natural" concurrent semantics that makes library support for concurrency superfluous. In addition, not only should sequential classes be reusable in a concurrent context, but concurrent classes should also be reusable in a sequential context. It is suggested that concurrency annotations be inserted into otherwise sequential code. They are ignored by a sequential compiler, but a compiler for the extended concurrent language will recognize them and generate the appropriate concurrent code. The concurrent version of the language supports active and concurrent objects and favours a declarative approach to synchronization and locking which solves typical concurrency problems in an easier and more readable way than previous approaches. Concurrency annotations are introduced using Eiffel as the sequential base.
