description: We propose that a system of colloidal particles interacting with a honeycomb array of optical traps that each contain three wells can be used to realize a fully packed loop model. One of the phases in this system can be mapped to Baxter's three-coloring problem, offering an easily accessible physical realization of this problem. As a function of temperature and interaction strength, we find a series of phases, including long range ordered loop or stripe states, stripes with sliding symmetries, random packed loop states, and disordered states in which the loops break apart. Our geometry could be constructed using ion trap arrays, BEC vortices in optical traps, or magnetic vortices in nanostructured superconductors.

Privileged mobility regimes and anxious futures: how whiteness shapes Australian migration to New York City
Creators: name: Wells, Dawn
Publisher: name: No Publisher Supplied
Year: 2023

description: This dissertation examines two interrelated topics. To understand why white, middle-class immigrants from Australia are seldom considered ‘immigrants’ in the United States, I examine how settler colonial logics have shaped racialized immigration regimes, focusing in particular on how immigrants associated with whiteness, wealth, and western culture are included through, not despite the law. To understand why white immigrants are surprised by their own palpable discomfort living in New York, I examine their experience as a form of what I term ‘race shock’ – the feeling of disorientation someone experiences when they are subjected to a new national racial context – a concept I offer as an ameliorative to the well-worn concept of culture shock. I suggest their experience of race shock offers insights into how whites are responding to the idea of white demographic decline and the waning power of liberalism and western imperial power.

description: For Classical T Tauri Stars (CTTSs), the resonance lines of N V, Si IV, and C IV, as well as the He II 1640 A line, act as diagnostics of the accretion process. Here we assemble a large high-resolution dataset of these lines in CTTSs and Weak T Tauri Stars (WTTSs). We present data for 35 stars: one Herbig Ae star, 28 CTTSs, and 6 WTTSs. We decompose the C IV and He II lines into broad and narrow Gaussian components (BC & NC). The most common (50 %) C IV line morphology in CTTSs is that of a low-velocity NC together with a redshifted BC. The velocity centroids of the BCs and NCs are such that V_BC > 4 * V_NC, consistent with the predictions of the accretion shock model, in at most 12 out of 22 CTTSs. We do not find evidence of the post-shock becoming buried in the stellar photosphere due to the pressure of the accretion flow. The He II CTTSs lines are generally symmetric and narrow, less redshifted than the CTTSs C IV lines, by ~10 km/sec. The flux in the BC of the He II line is small compared to that of the C IV line, consistent with models of the pre-shock column emission. The observations are consistent with the presence of multiple accretion columns with different densities or with accretion models that predict a slow-moving, low-density region in the periphery of the accretion column. For HN Tau A and RW Aur A, most of the C IV line is blueshifted suggesting that the C IV emission is produced by shocks within outflow jets. In our sample, the Herbig Ae star DX Cha is the only object for which we find a P-Cygni profile in the C IV line, which argues for the presence of a hot (10^5 K) wind. For the overall sample, the Si IV and N V line luminosities are correlated with the C IV line luminosities, although the relationship between Si IV and C IV shows large scatter about a linear relationship and suggests that TW Hya, V4046 Sgr, AA Tau, DF Tau, GM Aur, and V1190 Sco are silicon-poor.

description: A 1D code modelling SOL transport parallel to the magnetic field (SOLF1D) is benchmarked with 2D simulations of MAST-U SOL performed via the SOLPS code for two different collisionalities. Based on this comparison, SOLF1D is then used to model the effects of divertor leg stretching in 1D, in support of the planned Super-X divertor on MAST. The aim is to separate magnetic flux expansion from volumetric power losses due to recycling neutrals by stretching the divertor leg either vertically or radially.

title: Constraints and Opportunities in Community-Led Food Justice Models
Creators: name: Cuellar, Teya
Publisher: name: University of Kentucky Libraries
Year: 2019

description: Non-profits that do community-led food justice work with lower income communities face particular constraints and opportunities. This study examined those constraints and opportunities through participant observation of one such organization and interviews with four other organizations. Findings include the diversity of definitions for “community-led,” assets that can help or constrain the organization, and diversity in defining “scaling up” their organization models and missions. The organizations that heavily focused on lower income consumers noted tensions with the board of the non- profit and lack of engagement of consumers. I conclude by critiquing using language such as “models,” “scaling up,” or “replicating” when doing community-led food justice with lower income communities. I propose using the “scaling deep” framework (Moore, Riddell & Vocisano, 2015) and using Social Network Analysis as a tool for community development and developing alternative food initiatives with lower income individuals and communities.

description: Microwave signals, for example, those from Global Navigation Satellite Systems (GNSS) and very long baseline interferometry, are affected by tropospheric turbulence in such a way that the random fluctuations of the atmospheric index of refraction correlate the phase measurements. These atmospheric correlations are an important error source in space geodetic techniques. For computational reasons, they are neglected in positioning applications, to the detriment of a trustworthy description of the precision, and rigorous test statistics. Fortunately, modelling such correlations is possible by combining concepts from electromagnetic wave propagation in a random medium and the Kolmogorov turbulence theory. In this contribution, we will process single differences GNSS phase observations from a 300 m baseline between two different receivers linked to a common clock. After a preprocessing to filter additional error contributions, such as multipath, we will study the power spectral density of the phase residuals. We will estimate its low and high cutoff frequencies with an adapted unbiased Whittle maximum likelihood estimator. These cutoff frequencies – as predicted by turbulence theory – are related directly to the scale lengths of turbulence, i.e. the size of the eddies that correlate the GNSS observations. The study of their dependencies with the satellite geometry, day of the year, or time of the day provides new insights into the two- and three-dimensional atmospheric turbulence in the atmosphere. In addition, it contributes to improving the stochastic description of random effects impacting GNSS phase observations.

description: Recent rapid population growth and increasing urbanisation have led to fast vertical developments in urban areas. Therefore, in the context of the dynamic property market, factors related to the third dimension (3D) need to be considered. Current hedonic price modelling (HPM) studies have little explicit consideration for the third dimension, which may have a significant influence on modelling property values in complex urban environments. Therefore, our research aims to narrow the cognitive gap of the missing third dimension by assessing both 2D and 3D HPM and identifying important 3D factors for spatial analysis and visualisation in the selected study area, Xi’an, China. The statistical methods we used for 2D HPM are ordinary least squares (OLS) and geographically weighted regression (GWR). In 2D HPM, they both have very low R2 (0.111 in OLS and 0.217 in GWR), showing a very limited generalisation potential. However, a significant improvement is observed when adding 3D factors, namely view quality, sky view factor (SVF), sunlight and property orientation. The obtained higher R2 (0.414) shows the importance of the third dimension or—3D factors for HPM. Our findings demonstrate the necessity to include such factors into HPM and to develop 3D models with a higher level of details (LoD) to serve more purposes such as fair property taxation. © 2020 by the authors.

description: We report on the observation of coupling a single nitrogen vacancy (NV) center in a nanodiamond crystal to a propagating plasmonic mode of silver nanowires. The nanocrystal is placed either near to the apex of a single silver nanowire or in the gap between two end-to-end aligned silver nanowires. We observe an enhancement of the NV-centers' decay rate in both cases as a result of the coupling to the plasmons. The devices are nano-assembled with a scanning probe technique. Through simulations, we show that end-to-end aligned silver nanowires can be used as a controllable splitter for emission from a dipole emitter.

description: There has been a strong push recently to examine biological scale simulations of neuromorphic algorithms to achieve stronger inference capabilities. This paper presents a set of piecewise linear spiking neuron models, which can reproduce different behaviors, similar to the biological neuron, both for a single neuron as well as a network of neurons. The proposed models are investigated, in terms of digital implementation feasibility and costs, targeting large scale hardware implementation. Hardware synthesis and physical implementations on FPGA show that the proposed models can produce precise neural behaviors with higher performance and considerably lower implementation costs compared with the original model. Accordingly, a compact structure of the models which can be trained with supervised and unsupervised learning algorithms has been developed. Using this structure and based on a spike rate coding, a character recognition case study has been implemented and tested.

We find that exact solutions that span the attraction basin can be found even in the rotating case by appealing to certain symmetries of the equations of motion. They are characterized by two asymptotic parameters that generalize those of the non-rotating case, and the boundaries of the basin are spinning versions of the (generalized) subttractor geometry. We also give examples to illustrate that the shape of the attraction basin can drastically change depending on the theory.

description: The coupled system of the quark-gluon vertex and quark propagator Dyson-Schwinger equations (DSEs) is investigated within Landau gauge QCD. The aim is to get a deeper insight into the mechanisms of quark confinement and dynamical chiral symmetry breaking and into a possible relation between these two phenomena. To this end an earlier study is extended by improving systematically on the truncations imposed on the quark-gluon vertex DSE. A clear infrared enhancement for all tensor structures of the quark-gluon vertex is obtained.

description: Although the emergence of complex biomineralized forms has been investigated for over a century, still little is known on how single cells control morphology of skeletal structures, such as frustules, shells, spicules, or scales. We have run experiments on the shell formation in foraminifera, unicellular, mainly marine organisms that can build shells by successive additions of chambers. We used live imaging to discover that all stages of chamber/shell formation are controlled by dedicated actin-driven pseudopodial structures. Successive reorganization of an F-actin meshwork, associated with microtubular structures, is actively involved in formation of protective envelope, followed by dynamic scaffolding of chamber morphology. Then lamellar dynamic templates create a confined space and control mineralization separated from seawater. These observations exclude extracellular calcification assumed in selected foraminiferal clades, and instead suggest a semiintracellular biomineralization pattern known from other unicellular calcifying and silicifying organisms. These results give a challenging prospect to decipher the vital effect on geochemical proxies applied to paleoceanographic reconstructions. They have further implications for understanding multiscale complexity of biomineralization and show a prospect for material science applications.

The correlation between oil production and school enrollment rates: a comparison of government political systems and levels of control of corruption
Creators: name: Omar, Bushra
Publisher: name: No Publisher Supplied
Year: 2022

description: School enrollment rate is considered an important measure of a country’s educational system. Therefore, understanding what determines the fluctuation of these rates is an important objective in creating a strategy to maintain these rates high. This study examines the relationships between oil production and school enrollment rates of all educational levels. Taking into account different factors that might cause these relationships to be stronger or weaker. These factors are the real GDP, GDP per capita, the political system a country uses, and the level of control of corruption a country implements. Multiple linear regression analyses have been conducted to provide insight on the quantitative associations between the economic factors that might contribute to school enrollment rates and the strength of these associations. These factors and relationships are combined to explain the changes in school enrollment rates in different countries and show how oil production might or might not have an important role in school enrollment rates. The analyses indicates that oil production alone does not have a strong correlation to school enrollment rates. However, when linked with the other economic factors, the analyses show a strong correlation with some, and a weak correlation with others. Overall, we found that real GDP is the most effective factor on school enrollment in general, regardless of the source of revenue it came from. And only when combined with a more democratic political system and high levels of control of corruption.

description: We examine the full nonlinear dynamics of closed FRW universes in the framework of D-branes formalism. Friedmann equations contain additional terms arising from the bulk-brane interaction that provide a concrete model for nonsingular bounces in the early phase of the universe. We construct nonsingular cosmological scenarios sourced with perfect fluids and a massive inflaton field which are past eternal, oscillory and may emerge into an inflationary phase due to nonlinear resonance mechanisms. Oscillatory behaviour becomes metastable when the system is driven into a resonance window of the parameter space of the models, with consequent break-up of KAM tori that trap the inflaton, leading the universe to the inflationary regime. A construction of the resonance chart of the models is made. Resonance windows are labeled by an integer $n \geq 2$, where $n$ is related to the ratio of the frequencies in the scale factor/scalar field degrees of freedom. They are typically small compared to volume of the whole parameter space, and we examine the constraints imposed by nonlinear resonance in the physical domain of initial configurations so that inflation may be realized. We discuss the complex dynamics arising in this pre-inflationary stage, the structural stability of the resonance pattern and some of its possible imprints in the physics of inflation. We also approach the issue of initial configurations that are connected to a chaotic exit to inflation. Pure scalar field bouncing cosmologies are constructed. Contrary to models with perfect fluid components, the structure of the bouncing dynamics is highly sensitive to the initial amplitude and to the mass of the inflaton; dynamical potential barriers allowing for bounces appear as a new feature of the dynamics.
To Plan or To Continue Not to Plan in Western North Carolina...

Year: 1993

description: According to the 1990 census, North Carolina is, for the first time, more urban than rural. This change in demographic conditions has economic and natural resource implications for regional and state-wide growth management. Concerns regarding the ability of communities to effectively deal with growth management issues, particularly in the mountain area, resulted in legislative initiatives enacted by the 1991 North Carolina State Legislature. Senate Bill 917 created two study commissions to determine the need for mandated land-use planning in the mountain area of North Carolina (House Bill 1261) and for the state as a whole (House Bill 1157). Each initiative is controversial, due in part to both strongly held property-rights beliefs and misunderstandings about the role and usefulness of planning. This paper examines land-use planning issues in the mountain area of North Carolina, including the problems particular to the area, new perspectives that planning can bring to these problems, limitations placed on planning by the state and future directions for planning in western North Carolina.

Year: 1977

description: It is impossible to deny we are rapidly depleting the world's conventional energy supplies. In addition, the use of conventional energy results in billions of dollars in pollution costs each year. Household and commercial requirements account for about one-third of United States energy use and over one half of electricity demand. Over 70 per cent of the energy consumed in these sectors is for heating, cooling, and water heating. All three of these usages can be provided by existing solar technology. Implementation of that technology in North Carolina would result in a monetary savings to the individual homeowner and environmental savings to the public.

Oort Cloud and Scattered Disc formation during a late dynamical instability in the Solar System

Year: 2013
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: One of the outstanding problems of the dynamical evolution of the outer solar system concerns the observed population ratio between the Oort Cloud (OC) and the Scattered Disc (SD): observations suggest that this ratio lies between 100 and 1000 but simulations that produce these two reservoirs simultaneously consistently yield a value of the order of 10. Here we stress that the populations in the OC and SD are inferred from the observed fluxes of new Long Period Comets (LPCs) and Jupiter-family comets (JFCs), brighter than some reference total magnitude. However, the population ratio estimated in the simulations of formation of the SD and OC refers to objects bigger than a given size. There are multiple indications that LPCs are intrinsically brighter than JFCs, i.e. an LPC is smaller than a JFC with the same total absolute magnitude. When taking this into account we revise the SD/JFC population ratio from our simulations relative to Duncan and Levison (1997), and then deduce from the observations that the size-limited population ratio between the OC and the SD is 44 (-34)(+54). From simulations we obtain 12 +- 1 but the agreement cannot be rejected by the null hypothesis.

description: A successful model of high Reynolds number cavity flows involves reproducing the flow physics with adequate accuracy, given the available computational resources. The process of planning high Reynolds number cavity flow simulations is systematically reviewed to extract the dependence of different programmer’s choice on the CFD mesh size and on the cost of the computation. This process has been broken down into five phases: i) description of the problem in the continuous domain, ii) problem order reduction by turbulence modelling, iii) discretization in space and time, iv) integration of the governing equations, v) costing the numerical op- erations of the flow solver. This paper examines the influence of each phase on the spectral width and the grid density which are the key CFD indicators that determine the cost of the computation. A dimensional analysis was conducted to separate the effects of the geometry of the enclosure, the boundary layer resolution, the turbulence model and the numerical scheme order of accuracy. Regression analysis on the non-dimensional groups of published cavity CFD simulations determined the range of practical values used by current state-of-the-art computations. This analysis is a useful tool to obtain design trade-offs by a multivariate optimization in cavity flow CFD and for estimating the order of magnitude of computational resources required by the simulations.

description: Although many large planning agencies have utilized sophisticated computer-based analyses such as econometric forecasting and air pollution dispersion modeling for many years, numerous smaller agencies view computers as not feasible or even desirable for their operations. Computers can be very useful to small scale planning efforts, however. This article explores possible computer applications for modest planning settings. It examines the practical benefits small and medium size agencies can derive from computers, and responds to misconceptions that have kept these agencies from using computers in the past. Geocoding, an easily established computer application with many potential uses in the local planning setting is discussed and illustrated through the experience of the Durham, North Carolina City Planning Department.

Publisher: name: Old Dominion University Libraries
Year: 2001

description: The objective of this study was to examine the levels of estrogens, progesterone, LH, FSH, estradiol and testosterone and their relation to ACL laxity throughout the menstrual cycle. Subjects were tested at the onset of menses, the first day of ovulation (days 8–17) and day 23 at the mid-luteal phase. A Pearson Product Moment Correlation Coefficient revealed that there were no statistically significant relationships between laxity measurements, of the KT-2000 or radiographic comparisons, and elevated concentrations of any of the hormones. LH was observed in the follicular phase, at the onset of menses, to have a negative correlation with only the radiographic reading (r = −.628, p = .029). We concluded that there was no relationship between concentrations of estrogens, progesterone, LH, FSH, estradiol or testosterone and ACL laxity. Both the KT-2000 and radiographic measurements have high intra-method reliabilities, but inter-method reliability is low.

Such disasters require a different and creative approach to prevent chaos and the overuse of the highway system in evacuating metropolitan regions which could potentially lead to other harmful consequences.

High-Energy Gamma-Ray Emission From Solar Flares: Summary of Fermi LAT Detections and Analysis of Two M-Class Flares
Creators: name: LAT Collaboration
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We present the detections of 19 solar flares detected in high-energy gamma rays (above 100 MeV) with the Fermi Large Area Telescope (LAT) during its first four years of operation. Interestingly, all flares are associated with fairly fast Coronal Mass Ejections (CMEs) and are not all powerful X-ray flares. We then describe the detailed temporal, spatial and spectral characteristics of the first two long-lasting events: the 2011 March 7 flare, a moderate (M3.7) impulsive flare followed by slowly varying gamma-ray emission over 13 hours, and the 2011 June 7 M2.5 flare, which was followed by gamma-ray emission lasting for 2 hours. We compare the Fermi-LAT data with X-ray and proton data measurements from GOES and RHESSI. We argue that a hadronic origin of the gamma rays is more likely than a leptonic origin and find that the energy spectrum of the proton distribution softens after the 2011 March 7 flare, favoring a scenario with continuous acceleration at the flare site. This work suggests that proton acceleration in solar flares is more common than previously thought, occurring for even modest X-ray flares, and for longer durations.

description: Quantum physics is known to allow for completely new ways to create, manipulate and store information. Quantum communication - the ability to transmit quantum information - is a primitive necessary for any quantum internet. At its core, quantum communication generally requires the formation of entangled links between remote locations. The performance of these links is limited by the classical signaling time between such locations - necessitating the need for long lived quantum memories. Here we present the design of a communications network which neither requires the establishment of entanglement between remote locations nor the use of long-lived quantum memories. The rate at which quantum data can be transmitted along the network is only limited by the time required to perform efficient local gate operations. Our scheme thus potentially provides higher communications rates than previously thought possible.
title: Television and the Integration of Europe in the Era of Satellite Communications
Creators: name: Roos, John Erick
Publisher: name: Old Dominion University Libraries
Year: 1988

description: The role television played in the integration of Europe through 1987 is examined in an analysis focusing on historical trends, integration theory, and the effect of satellite technology on the political environment in Europe. Television remained under the jurisdiction of national governments since its inception, satellite communications challenged the system of national control of television and changed television's role in Europe by introducing a revolutionary new delivery system. Integration theorists are cited to define the integration process and provide a foundation for a study of television's impact on European integration. Television policies in each nation are examined to document their past nationalistic nature. Intergovernmental organizations are surveyed to understand their function in the formulation of European television policies. The private sector's use of satellites is cited to document how its actions encouraged integration in the marketplace. It is shown that the integration of the television market will precede European integration and that satellite television provided the communication tool that will stimulate this integration.
title: Franco-American Relations and the Emergence of French Nuclear Armament, 1939-1962

description: France and the United States stand out as two major pioneer countries in the development of nuclear science. It was logical for France to join the nuclear club. But due to the extended responsibilities such an option implies, a lengthy difference of opinion developed between France and the United States. The former asserted its rights and its worldwide influence heedless of the decolonization process. The latter, heavily committed to the Western defense and its global interests, opposed the development of a strike force that it could not control. This disagreement led France to make specific reservations toward decision-making of the Atlantic Alliance's military body. This study, based on memoirs and published documents, reviews the military aspects of the nuclear relationship between both nations from the late 1930s to 1962. It concludes that the French military nuclear program revealed the two nations' differing perception of their sovereignty and international role. France gained through this program a technological edge which clearly ensues from de Gaulle's steadfast policy.
Construction of holomorphic local conformal framed nets

description: We construct holomorphic local conformal framed nets extended from a tensor power of the Virasoro net with c=1/2 with a pair of binary codes (C,D) satisfying the conditions given by Lam and Yamauchi for holomorphic framed vertex operator algebras. Our result is an operator algebraic counterpart of theirs, but our proof is entirely different. We apply the alpha-induction in order to identify the representation theory of "code local conformal net" and this gives rise to the existence of the desired local conformal net.
Inverse cascade behavior in freely decaying two-dimensional fluid turbulence

description: We present results from an ensemble of 50 runs of two-dimensional hydrodynamic turbulence with spatial resolution of 2048^2 grid points, and from an ensemble of 10 runs with 4096^2 grid points. All runs in each ensemble have random initial conditions with same initial integral scale, energy, enstrophy, and Reynolds number. When both ensemble- and time-averaged, inverse energy cascade behavior is observed, even in the absence of external mechanical forcing: the energy spectrum at scales larger than the characteristic scale of the flow follows a k^(-5/3) law, with negative flux, together with a k^(-3) law at smaller scales, and a positive flux of enstrophy. The source of energy for this behavior comes from the modal energy around the energy containing scale at t=0. The results shed some light into connections between decaying and forced turbulence, and into recent controversies in experimental studies of two-dimensional and magnetohydrodynamic turbulent flows.

description: We analyze the force on a point charge moving at relativistic speeds parallel to the surface of a uniaxial dielectric. Two cases are examined: a lossless dielectric with no dispersion and a dielectric with a plasma type response. The treatment focuses on the peculiarities of the strength and direction of the interaction force as compared to the isotropic case. We show that a plasma type dielectric can, under specific conditions, repel the point charge.

description: Planners often fail to fulfill their leadership qualities or realize their leadership potential. But the reasons planners give for not owning up to their leadership potential are often the same reasons why planners should lead. This article explores the reasons most often given for the lack of leadership among planners, a simple methodology which can put these qualities into action, and finally, a case study in which this methodology was used to provide leadership in an issue at the state level.
