UNC-DCRP Best Master’s Project of 2007: North Carolina’s Aero/Space Economy: Current Performance and Future Potential...Revisited
Creators: name: Harris, Christopher M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: As North Carolina’s economy shifts from one based in agriculture and textile manufacturing to a new economy founded on technological advancement, Harris explores through his award-winning study the strength and potential of the aero/space industry within North Carolina’s borders. A joint recipient of DCRP’s distnction of Best Master’s Project of 2007, Harris’ report gives an indepth look at this industry as it stands in this state and carefully details the resources the aero/space field can draw upon for future growth and expansion. He also assesses the state’s performance and potential within this industry relative to three other similarly situated states around the country. Though only an exerpt of this extensive study is presented here, the report’s findings offer a comprehensive assessment of North Carolina’s current position and future potential in the aero/space industry.
Book Review: Good Jobs, Bad Jobs
Creators: name: Hunt, Heather
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Arne Kalleberg’s Good Jobs, Bad Jobs is a deft and concentrated dose of gloom. Kalleberg’s central thesis - that the political, social and economic changes of the past 30 years have permanently altered the structure of the American labor system - is simple, but portends profound ramifications. Among these, according to Kalleberg, is that work has become both more polarized and more precarious.

description: We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of $147$ stellar targets along the line of sight to the newly-discovered `ultrafaint' stellar systems Tucana 2 (Tuc 2) and Grus 1 (Gru 1). Based on simultaneous estimates of line-of-sight velocity and stellar-atmospheric parameters, we identify 8 and 7 stars as probable members of Tuc 2 and and Gru 1, respectively. Our sample for Tuc 2 is sufficient to resolve an internal velocity dispersion of $8.6_{-2.7}^{+4.4}$ km s$^{-1}$ about a mean of $-129.1_{-3.5}^{+3.5}$ km s$^{-1}$ (solar rest frame), and to estimate a mean metallicity of [Fe/H]= $-2.23_{-0.12}^{+0.18}$. These results place Tuc 2 on chemodynamical scaling relations followed by dwarf galaxies, suggesting a dominant dark matter component with dynamical mass $2.7_{-1.3}^{+3.1}\times 10^6$ $\mathrm{M}_{\odot}$ enclosed within the central $\sim 160$ pc, and dynamical mass-to-light ratio $1900_{-900}^{+2200}$ $\mathrm{M}_{\odot}/L_{V,\odot}$. For Gru 1 we estimate a mean velocity of $-140.5_{-1.6}^{+2.4}$ km s$^{-1}$ and a mean metallicity of [Fe/H]=$-1.42_{-0.42}^{+0.55}$, but our sample does not resolve Gru 1's velocity dispersion. The radial coordinates of Tuc 2 and Gru 1 in Galactic phase space suggest that their orbits are among the most energetic within distance $\leq 300$ kpc. Moreover, their proximity to each other in this space arises naturally if both objects are trailing the Large Magellanic Cloud.

description: Including prior information about model parameters is a fundamental step of any Bayesian statistical analysis. It is viewed positively by some as it allows, among others, to quantitatively incorporate expert opinion about model parameters. It is viewed negatively by others because it sets the stage for subjectivity in statistical analysis. Certainly, it creates problems when the inference is skewed due to a conflict with the data collected. According to the theory of conflict resolution (O'Hagan and Pericchi, 2012), a solution to such problems is to diminish the impact of conflicting prior information, yielding inference consistent with the data. This is typically achieved by using heavy-tailed priors. We study both theoretically and numerically the efficacy of such a solution in a regression framework where the prior information about the coefficients takes the form of a product of density functions with known location and scale parameters. We study functions with regularly varying tails (Student distributions), log-regularly-varying tails (as introduced in Desgagné (2015)), and propose functions with slower tail decays that allow to resolve any conflict that can happen under that regression framework, contrarily to the two previous types of functions. The code to reproduce all numerical experiments is available online.

Measuring Medical Doctor Activation in Academic Medicine in Australia and the USA

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Despite general acceptance that clinician engagement delivers positive outcomes for healthcare organisations, uniform understanding of the concept and ability to effectively measure and link it to outcomes remains limited. Drawing on the literature and the concept of the valid and reliable Patient Activation Measure, this study conceptualises a defined and measurable concept of ‘doctor activation’. Doctor activation was defined for this purpose as the ability and motivation of medical doctors in regularly and actively contributing to sustaining or improving the delivery of high value, patient-centred care. The study developed - through an evidence-based, co-production process - a new, purpose-designed survey, the Measure of Doctor Activation (MD-A). The MD-A was implemented at two academic health systems in Australia and the USA and evaluated for validity and reliability as a tool. Finally, the results were analysed in concert with semi-structured interview findings to provide a two-country and site comparison of doctor activation. The MD-A was shown to be a valid and reliable, 18-item scale for measuring activation of medical doctors. Differences were demonstrated in predictors and detractors of activation at the two sites, given their different contexts and levels of maturity as academic health systems. The study demonstrated a correlation between doctor activation and tangible results being delivered for the organisation (as measured by initiation and leadership of new model of care, quality improvement or strategic initiatives). In summary, the MD-A is a valid, reliable, and potentially high utility tool to measure the activation level of doctors across organisations, countries, and contexts, with a view to continuous improvement.

description: A superconducting transition temperature Tc as high as 100 K was recently discovered in 1 monolayer (1ML) FeSe grown on SrTiO3 (STO). The discovery immediately ignited efforts to identify the mechanism for the dramatically enhanced Tc from its bulk value of 7 K. Currently, there are two main views on the origin of the enhanced Tc; in the first view, the enhancement comes from an interfacial effect while in the other it is from excess electrons with strong correlation strength. The issue is controversial and there are evidences that support each view. Finding the origin of the Tc enhancement could be the key to achieving even higher Tc and to identifying the microscopic mechanism for the superconductivity in iron-based materials. Here, we report the observation of 20 K superconductivity in the electron doped surface layer of FeSe. The electronic state of the surface layer possesses all the key spectroscopic aspects of the 1ML FeSe on STO. Without any interface effect, the surface layer state is found to have a moderate Tc of 20 K with a smaller gap opening of 4 meV. Our results clearly show that excess electrons with strong correlation strength alone cannot induce the maximum Tc, which in turn strongly suggests need for an interfacial effect to reach the enhanced Tc found in 1ML FeSe/STO.

Book Review: Refining the Waterfront, Alternative Energy Facility Siting Policies for Urban Coastal Areas
Creators: name: Blomberg, Georgiana Dix
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1980

description: Another conflict in a long line of officially recognized, but yet to be manifested, conflicting demands on our beleaguered coasts has come to the forefront: it is one between the growing interest in and revitalization of neglected urban waterfronts and the need to site a number of new energy facilities; many of them built or predicted in conjunction with Outer Continental oil and gas recovery. The conflict may be the greatest in the northeast; because the northeast is the major market for energy in the eastern United States, it is the region most often preferred for energy facility siting. However, there are quite a few factors, Coastal Zone Management policies among them, which direct development away from pristine or natural areas. As corporations attempt to locate energy facilities in northeastern urban areas, they are more and more unsuccessful - turned away by the efforts of the city's and region's citizens, newly interested in the possibilities and promises of their rediscovered waterfronts. David Morell and Grace Singer, principal authors of Refining the Waterfront, Alternative Energy Facility Siting Policies for Urban Coastal Areas, are convinced that siting strategies "could support, rather than contradict, the innovative redevelopment efforts now underway in many urban waterfronts." (p. 285) They maintain that an energy facility siting strategy must be made compatible with three "critical national priorities:" greater energy self sufficiency, urban revitalization, and protection of fragile rural coastlines.

description: We propose two novel nonparametric two-sample kernel tests based on the Maximum Mean Discrepancy (MMD). First, for a fixed kernel, we construct an MMD test using either permutations or a wild bootstrap, two popular numerical procedures to determine the test threshold. We prove that this test controls the probability of type I error non-asymptotically. Hence, it can be used reliably even in settings with small sample sizes as it remains well-calibrated, which differs from previous MMD tests which only guarantee correct test level asymptotically. When the difference in densities lies in a Sobolev ball, we prove minimax optimality of our MMD test with a specific kernel depending on the smoothness parameter of the Sobolev ball. In practice, this parameter is unknown and, hence, the optimal MMD test with this particular kernel cannot be used. To overcome this issue, we construct an aggregated test, called MMDAgg, which is adaptive to the smoothness parameter. The test power is maximised over the collection of kernels used, without requiring held-out data for kernel selection (which results in a loss of test power), or arbitrary kernel choices such as the median heuristic. We prove that MMDAgg still controls the level non-asymptotically, and achieves the minimax rate over Sobolev balls, up to an iterated logarithmic term. Our guarantees are not restricted to a specific type of kernel, but hold for any product of one-dimensional translation invariant characteristic kernels. We provide a user-friendly parameter-free implementation of MMDAgg using an adaptive collection of bandwidths. We demonstrate that MMDAgg significantly outperforms alternative state-of-the-art MMD-based two-sample tests on synthetic data satisfying the Sobolev smoothness assumption, and that, on real-world image data, MMDAgg closely matches the power of tests leveraging the use of models such as neural networks.

description: We study the lensing effect experienced by a weak probe field under conditions of electromagnetically induced transparency (EIT) involving a Rydberg state. A Gaussian coupling beam tightly focused on a laser-cooled atomic cloud produces an inhomogeneity in the coupling Rabi frequency along the transverse direction and makes the EIT area acting like a gradient-index medium. We image the probe beam at the position where it exits the atomic cloud, and observe that a red-detuned probe light is strongly focused with a greatly enhanced intensity whereas a blue-detuned one is de-focused with a reduced intensity. Our experimental results agree very well with the numerical solutions of Maxwell-Bloch equations.

description: We carry out a systematic qualitative analysis of the two quadratic schemes of generalized oscillators recently proposed by C. Quesne [J.Math.Phys.\textbf{56},012903 (2015)]. By performing a local analysis of the governing potentials we demonstrate that while the first potential admits a pair of equilibrium points one of which is typically a center for both signs of the coupling strength $λ$, the other points to a centre for $λ< 0$ but a saddle $λ> 0$. On the other hand, the second potential reveals only a center for both the signs of $λ$ from a linear stability analysis. We carry out our study by extending Quesne's scheme to include the effects of a linear dissipative term. An important outcome is that we run into a remarkable transition to chaos in the presence of a periodic force term $f\cos ωt$.

description: To separate scintillation and Cherenkov lights in water-based liquid scintillator detectors is a desired feature for future neutrino and proton decay researches. Linear alkyl benzene (LAB) is one important ingredient of a water-based liquid scintillator being developed. In this paper we observed a good separation of scintillation and Cherenkov lights in an LAB sample. The rising and decay times of the scintillation light of the LAB were measured to be $(7.7\pm3.0)\ \rm{ns}$ and $(36.6\pm2.4)\ \rm{ns}$, respectively, while the full width [-3$σ$, 3$σ$] of the Cherenkov light was 12 ns dominated by the time resolution of our photomultiplier tubes. The light yield of the scintillation was measured to be $(1.01\pm0.12)\times10^3\ \rm{photons}/\rm{MeV}$.

description: We consider selecting the top-$m$ alternatives from a finite number of alternatives via Monte Carlo simulation. Under a Bayesian framework, we formulate the sampling decision as a stochastic dynamic programming problem, and develop a sequential sampling policy that maximizes a value function approximation one-step look ahead. To show the asymptotic optimality of the proposed procedure, the asymptotically optimal sampling ratios which optimize large deviations rate of the probability of false selection for selecting top-$m$ alternatives has been rigorously defined. The proposed sampling policy is not only proved to be consistent but also achieves the asymptotically optimal sampling ratios. Numerical experiments demonstrate superiority of the proposed allocation procedure over existing ones.

description: The Lipschitz constant of the map between the input and output space represented by a neural network is a natural metric for assessing the robustness of the model. We present a new method to constrain the Lipschitz constant of dense deep learning models that can also be generalized to other architectures. The method relies on a simple weight normalization scheme during training that ensures the Lipschitz constant of every layer is below an upper limit specified by the analyst. A simple monotonic residual connection can then be used to make the model monotonic in any subset of its inputs, which is useful in scenarios where domain knowledge dictates such dependence. Examples can be found in algorithmic fairness requirements or, as presented here, in the classification of the decays of subatomic particles produced at the CERN Large Hadron Collider. Our normalization is minimally constraining and allows the underlying architecture to maintain higher expressiveness compared to other techniques which aim to either control the Lipschitz constant of the model or ensure its monotonicity. We show how the algorithm was used to train a powerful, robust, and interpretable discriminator for heavy-flavor-quark decays, which has been adopted for use as the primary data-selection algorithm in the LHCb real-time data-processing system in the current LHC data-taking period known as Run 3. In addition, our algorithm has also achieved state-of-the-art performance on benchmarks in medicine, finance, and other applications.

description: We derive relations between viscosities and momentum conductivity in $2+1$ dimensions by finding a generalization of holographic Ward identities for the energy-momentum tensor. The generalization is novel in the sense that it goes beyond the usual identities obtained from holographic renormalization. Our results are consistent with previous field theory analysis. The main tools we use are a constant `probability current' in the gravity dual, that we are able to define for any system of linear ODEs, and parity symmetry.

Book Review: Urban Design and the Bottom Line: Optimizing the Return on Perception
Creators: name: Campbell, Amanda
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: A glowing stadium shaped like a large blue doughnut (Munich’s Allianz Arena) and the “lively layouts and fresh designs” of The Grove (Los Angeles’ lifestyle center) are but two of the colorful examples highlighted in Urban Design and the Bottom Line: Optimizing the Return on Perception, by Dennis Jerke and contributing authors Douglas R. Porter and Terry J. Lassar. The work, recently published by the Urban Land Institute, highlights international urban design case studies and is accessible to any audience. Rather than serving as a textbook for urban design rules, this book paints broad principles using striking photographs and descriptive language. The authors use examples of success to demonstrate good urban design, backing up their claims with data and observed results. While the graphics alone would make it an excellent coffee-table book, the text contains a surprising amount of detail on a wide scope of material drawn from industry experts, making it an excellent resource for those unfamiliar with urban and environmental design. For practitioners, the case studies may inspire and justify future projects.

description: The Einstein Telescope is a conceived third generation gravitational-wave detector that is envisioned to be an order of magnitude more sensitive than advanced LIGO, Virgo and Kagra, which would be able to detect gravitational-wave signals from the coalescence of compact objects with waveforms starting as low as 1Hz. With this level of sensitivity, we expect to detect sources at cosmological distances. In this paper we introduce an improved method for the generation of mock data and analyse it with a new low latency compact binary search pipeline called gstlal. We present the results from this analysis with a focus on low frequency analysis of binary neutron stars. Despite compact binary coalescence signals lasting hours in the Einstein Telescope sensitivity band when starting at 5 Hz, we show that we are able to discern various overlapping signals from one another. We also determine the detection efficiency for each of the analysis runs conducted and and show a proof of concept method for estimating the number signals as a function of redshift. Finally, we show that our ability to recover the signal parameters has improved by an order of magnitude when compared to the results of the first mock data and science challenge. For binary neutron stars we are able to recover the total mass and chirp mass to within 0.5% and 0.05%, respectively.

description: The microtubule is a cylindrical biological polymer that plays key roles in cellular structure, transport, and signalling. In this work, based on studies of electronic properties of polyacetelene and mechanical properties of microtubules themselves (see Phys. Rev. Lett. 103, 248101), we explore the possibility that microtubules could act as topological insulators that are gapped to electronic excitations in the bulk but possess robust electronic bounds states at the tube ends. Through analyses of structural and electronic properties, we model the microtubule as a cylindrical stack of Su-Schrieffer-Heeger chains (originally proposed in the context of polyacetylene) describing electron hopping between the underlying dimerized tubulin lattice sites. We postulate that the microtubule is mostly uniform, dominated purely by GDP-bound dimers, and is capped by a disordered regime due to the presence of GTP-bound dimers as well. In the uniform region, we identify the electron hopping parameter regime in which the microtubule is a topological insulator. We then show the manner in which these topological features remain robust when the hopping parameters are disordered. We briefly mention possible biological implications for these microtubules to possess topologically robust electronic bound states.

GL_n(F_q)-analogues of factorization problems in the symmetric group

Publisher: name: arXiv

description: We consider GL_n(F_q)-analogues of certain factorization problems in the symmetric group S_n: rather than counting factorizations of the long cycle (1, 2, ..., n) given the number of cycles of each factor, we count factorizations of a regular elliptic element given the fixed space dimension of each factor. We show that, as in S_n, the generating function counting these factorizations has attractive coefficients after an appropriate change of basis. Our work generalizes several recent results on factorizations in GL_n(F_q) and also uses a character-based approach. As an application of our results, we compute the asymptotic growth rate of the number of factorizations of fixed genus of a regular elliptic element in GL_n(F_q) into two factors as n goes to infinity. We end with a number of open questions.

description: We consider a model of neutrino mass with a scalar triplet $(ξ^{++},ξ^+,ξ^0)$ assigned lepton number $L=0$, so that the tree-level Yukawa coupling $ξ^0 ν_i ν_j$ is not allowed. It is generated instead through the interaction of $ξ$ and $ν$ with dark matter and the soft breaking of $L$ to $(-1)^L$. We discuss the phenomenological implications of this model, including $ξ^{++}$ decay and the prognosis of discovering the dark sector at the Large Hadron Collider.

description: Janus transition metal dichalcogenides, with intrinsic mirror asymmetry, exhibit a wide array of interesting properties. In this work, we study Janus monolayers derived from WTe$_2$ using first-principles and tight-binding calculations. We discover that WSeTe and WSTe are topologically trivial, in contrast to the parent quantum spin Hall insulator WTe$_2$. Motivated by the growing interest in non-linear Hall effect, which also requires asymmetric structures, we investigate the Berry curvature and its dipole in these Janus systems and find that they exhibit strikingly large values of Berry curvature dipole, despite being in the topologically trivial phase. We track down the origin of this behaviour and put forth a low-energy massive Dirac model to understand the central features of our ab initio computations. Our predictions introduce Janus monolayers as promising new platforms for exploring as well as engineering non-linear Hall effect.

The Site-Value Tax: Its Potential Effect on Urban and County Land Uses in North Carolina

description: Of the many factors deemed responsible for the decay of our central cities, one which is consistently cited as a major problem is the property tax. It is charged with encouraging urban blight and ugliness, generating urban sprawl and the inefficient use of land, and unfairly burdening those who are least able to pay. Cities and states have reacted to these problems in a piecemeal fashion, enacting various tax abatement or exemption programs when inequities and inefficiency became too onerous. But these programs are limited in their effectiveness by their lack of a systematic approach to the inherent weaknesses of the property tax system. Often proposed as a reasonable alternative to the current property tax system is what is known as a site-value tax. Henry George, an American economist, began lauding its virtues almost one hundred years ago. But in spite of the theoretical validity of arguments made by its proponents, few taxing jurisdictions have seriously considered site-value taxation as an alternative to the present system, and fewer still have implemented any form of it. Economic theorists have thoroughly explored the expected effects of the tax, but there is a dearth of research focusing on the actual assessment figures of existing taxing jurisdictions and the effect which site-value taxation would have on specific types of land uses within the community. This paper, after briefly reviewing the theoretical arguments in favor of site-value taxation, investigates the effects which a site-value taxation system would have on various land use categories in two North Carolina urban centers and their counties—Charlotte and Mecklenburg County, and Durham and Durham County.
