Year: 1977

description: Includes an introduction to the theme of the journal issue and an overview of the problem. Introduction: This issue of Carolina planning focuses on energy. The magazine's coverage includes a number of policy alternatives pertinent to state, local, and national decision-makers in their deliberation over the energy problem. To provide some background information, the periodical begins with a short look at energy patterns and the institutional arrangements presently existing in North Carolina to manage resources. Next, an article and comment discusses national and state strategies for combatting a future petroleum crisis like the 1973 Arab oil embargo. Then, the benefits of a peak load pricing scheme are explained and proposed for North Carolina utilities. Following, are three articles on two widely discussed alternative energy forms: the Liquid Metal Fast Breeder Reactor and solar energy. The magazine concludes with an elaboration on energy conservation and the special role local governments might play in the effort. This collection, we feel, provides a broadly-based, yet in-depth assessment of important aspects of the state's and nation's energy problems, from the point of view of the planner, government official, and citizen. An Overview: Over the past three decades, North Carolina, like the rest of the nation, has seen a spectacular rise in the consumption of energy. What are the major forms of energy use in North Carolina? Basically, the state's power comes from four sources: electricity (which is generated from coal, nuclear, hydroelectric, and fuel oil power), natural gas, gasoline, and fuel oil. How do the trends for each source measure up, and what plans are being made for management of the state's energy resources? The following description presents a brief overview of the existing situation, in terms of demand and supply of existing resources, and their management, in order to provide background information for this energy issue.

description: Predefined spatial templates to describe the background of $γ$-ray emission from astrophysical processes, like cosmic ray interactions, are used in previous searches for the $γ$-ray signatures of annihilating galactic dark matter. In this proceeding, we investigate the GeV excess in the inner Galaxy using an alternative approach, in which the astrophysical components are identified solely by their spectral and morphological properties. We confirm the reported GeV excess and derive related parameters for dark matter interpretation, which are consistent with previous results. We investigate the morphology of this spectral excess as preferred by the data only. This emission component exhibits a central Galaxy cusp as expected for a dark matter annihilation signal. However, Galactic disk regions with a morphology of that of the hot interstellar medium also host such a spectral component. This points to a possible astrophysical origin of the excess and requests a more detailed understanding of astrophysical $γ$-ray emitting processes in the galactic center region before definite claims about a dark matter annihilation signal can be made.

description: We give an elementary topological obstruction for a manifold $M$ of dimension $2q{+}1 \geq 7$ to admit a contact open book with flexible Weinstein pages and $c_1(π_2(M)) = 0$: if the torsion subgroup of the $q$-th integral homology group is non-zero, then no such contact open book exists. We achieve this by proving that a symplectomorphism of a flexible Weinstein manifold acts trivially on cohomology. We also produce examples of non-trivial loops of flexible contact structures using related ideas.

title: Tracing the idea in Schoenberg's Violin Concerto: an interpretation through performance practice, analysis and recording analysis
Creators: name: Chatziiosifidis, Stelios
Publisher: name: University of Kent
Year: 2023

description: Schoenberg's twelve-tone music has attracted widespread musicological research and attention. The performance of his twelve-tone music, however, has not received the same prominence. The tension between these two opposing trends is the foundation of this thesis, which applies academic research to shaping an interpretation that leads to a performance of Schoenberg's Violin Concerto. In order to understand Schoenberg's musical thinking this study begins with the exploration of his concept of performance practice, identifying and organising the manifold issues around the concept of the Idea. In chapter two the Idea is traced in the material of the Violin Concerto, demonstrating how it can be associated with a specific group of notes, the tetrachord set-class 4-3. The appearance of this tetrachord in key moments, and the intention to project large-scale sections of the movements, influence the performer-oriented analysis at the end of chapter two. The performer-oriented analysis includes graphs that combine information about dynamics, tempo and a score reduction in order to assist the performer in his task of shaping each section. Chapter three explores the extent to which the projection of these large-scale sections occurs successfully in other recordings. The recording analysis program Sonic Visualiser has been employed in order to assist this research. The research focuses mainly on a contemporary recording, which at the time of the research was the most recent, and a recording that was in close proximity to Schoenberg and his circle: the 2000 recording with Rolf Schulte and Robert Craft (Philhannonia Orchestra) and the 1967 recording of Rudolf Kolisch and Rene Leibowitz (Wisconsin Festival Orchestra). Louis Krasner's 1954 recording with Dimitri Mitropoulos (Cologne Radio Orchestra) is also briefly examined, in order to make a comparison with another violinist that premiered the Concerto and was close to Schoenberg's circle. Chapter four amalgamates the previous research findings in order to produce three graphs, one for each movement, that outline a personal interpretation of the Concerto. The emphasis of these graphs focuses on the handling of tempo and how it influences the projection of large-scale sections that " organically connect to each other. At the end of the chapter the discussion returns to the performance practice issues outlined in chapter one, in order to demonstrate how they fit within the proposed interpretation of the piece.

description: We develop a systematic theory of eventually positive semigroups of linear operators mainly on spaces of continuous functions. By eventually positive we mean that for every positive initial condition the solution to the corresponding Cauchy problem is positive for large enough time. Characterisations of such semigroups are given by means of resolvent properties of the generator and Perron--Frobenius type spectral conditions. We apply these characterisations to prove eventual positivity of several examples of semigroups including some generated by fourth order elliptic operators and a delay differential equation. We also consider eventually positive semigroups on arbitrary Banach lattices and establish several results for their spectral bound which were previously only known for positive semigroups.

description: Semi-supervised learning an attractive technique in practical deployments of deep models since it relaxes the dependence on labeled data. It is especially important in the scope of dense prediction because pixel-level annotation requires significant effort. This paper considers semi-supervised algorithms that enforce consistent predictions over perturbed unlabeled inputs. We study the advantages of perturbing only one of the two model instances and preventing the backward pass through the unperturbed instance. We also propose a competitive perturbation model as a composition of geometric warp and photometric jittering. We experiment with efficient models due to their importance for real-time and low-power applications. Our experiments show clear advantages of (1) one-way consistency, (2) perturbing only the student branch, and (3) strong photometric and geometric perturbations. Our perturbation model outperforms recent work and most of the contribution comes from photometric component. Experiments with additional data from the large coarsely annotated subset of Cityscapes suggest that semi-supervised training can outperform supervised training with the coarse labels.

Federal Consistency and Dispute Resolution
Creators: name: Cogan, Jessica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: The 1970s marked a new era of environmental protection efforts in the United States. One major piece of legislation passed by Congress was the 1972 Coastal Zone Management Act (CZMA), which established a program to provide for the wise use and protection of the nation's coastal resources. Issues such as the loss of coastal and marine resources and wildlife, decreased public space, multiple use conflicts, and shoreline erosion have been a focus of this legislation. This article discusses the authority granted to state coastal zone management (CZM) programs pursuant to Section 307 of the CZMA. In particular, it focuses on the use of the federal consistency process as a tool for resolving intergovernmental disputes. In order to illustrate some of the issues surrounding the use of the federal consistency process, this article examines the legal questions surrounding a recent dispute which resulted in an appeal to the United States Secretary of Commerce by the Virginia Electric and Power Company (VEPCO). The Secretary's decision in this matter has important implications for a state CZM program's role in the federal consistency process.
Local Economic Development Planning in an Era of Capital Mobility

Year: 1981

description: Capital mobility is the technical term used by policy analysts to describe the movement of industry from one place to another, often between declining and growing local economies. This subject has recently become a topic of considerable research and policy interest at two levels. First, researchers have been concerned with a tendency of corporate forces and national policies to foster a polarization of local economic conditions: disinvestment and plant shutdowns in declining areas simultaneous with reinvestment and plant relocation in growing areas. Second, the accelerated pace of disinvestment-reinvestment since the mid-seventies has begun to be identified as a serious problem for both declining and growing areas.

Utilizing a detailed financial behavior survey of metaverse landowners' intrinsic and extrinsic motivations, we apply principal components analysis to uncover four distinct motivational groups: (1) Aesthetics and Identity, (2) Social and Community, (3) Speculation and Investment, and (4) Innovation and Technology. Our findings reveal that age, education, investment knowledge, risk-taking, and impulsivity significantly influence investor group membership. This research provides valuable insights to investors and developers, underscoring the potential of a platform to attract retail investors with speculative intentions, engagement longevity, and passive or active trading characteristics, contingent on unique crypto-metaverse attributes.

description: We study the impact of non-local modifications of General Relativity on stellar structure. In particular, assuming an analytic distortion function and specific equations of state, we made use of remnant stars to put qualitative constraints on a parameter not directly restricted by solar system tests. Using current data sets available for white dwarfs and strange quark stars candidates we find that the most stringent bounds come from the objects displaying the highest core densities, namely strange quark stars. Specifically, the constraints obtained from this class of stars are three to four orders of magnitude tighter than those obtained using white dwarfs.

description: Magnetic reconnection requires, at least locally, a non-ideal plasma response. In collisionless space and astrophysical plasmas, turbulence could permit this instead of the too rare binary collisions. We investigated the influence of turbulence on the reconnection rate in the framework of a single fluid compressible MHD approach. The goal is to find out, whether unresolved, sub-grid for MHD simulations, turbulence can enhance the reconnection process in high Reynolds number astrophysical plasma. We solve, simultaneously with the grid-scale MHD equations, evolution equations for the sub-grid turbulent energy and cross helicity according to Yokoi's model (Yokoi (2013)) where turbulence is self-generated and -sustained through the inhomogeneities of the mean fields. Simulations of Harris and force free sheets confirm the results of Higashimori et al. (2013) and new results are obtained about the dependence on resistivity for large Reynolds number as well as guide field effects. The amount of energy transferred from large to the small scales is enhanced in case of fast turbulent reconnection and energy spectra are used to interpret the obtained regime of reconnection controlled by the turbulence timescale $τ_t$. The overall process is even faster for larger Reynolds numbers controlled by the background molecular resistivity $η$, as long as the initial level of turbulence is not too large. This implies that turbulence plays an important role on fast reconnection at situation of large Reynolds number while the amplitude of turbulence can still be small.

description: The photoluminescence intermittency (blinking) of quantum dots is interesting because it is an easily-measured quantum process whose transition statistics cannot be explained by Fermi's Golden Rule. Commonly, the transition statistics are power-law distributed, implying that quantum dots possess at least trivial memories. By investigating the temporal correlations in the blinking data, we demonstrate with high statistical confidence that quantum dot blinking data has non-trivial memory, which we define to be statistical complexity greater than one. We show that this memory cannot be discovered using the transition distribution. We show by simulation that this memory does not arise from standard data manipulations. Finally, we conclude that at least three physical mechanisms can explain the measured non-trivial memory: 1) Storage of state information in the chemical structure of a quantum dot; 2) The existence of more than two intensity levels in a quantum dot; and 3) The overlap in the intensity distributions of the quantum dot states, which arises from fundamental photon statistics.

description: A remarkable example of reducing Stroop interference is provided by the word blindness post-hypnotic suggestion (a suggestion to see words as meaningless during the Stroop task). This suggestion has been repeatedly demonstrated to halve Stroop interference when it is given to highly hypnotisable people. In order to explore how highly hypnotisable individuals manage to reduce Stroop interference when they respond to the word blindness suggestion, we tested four candidate strategies in two experiments outside of the hypnotic context. A strategy of looking-away from the target words, and a strategy of visual blurring demonstrated compelling evidence for substantially reducing Stroop interference in both experiments. However, the pattern of results produced by these strategies did not match those of the word blindness suggestion. Crucially, neither looking-away nor visual blurring managed to speed up incongruent responses, suggesting that neither of these strategies are likely underlying mechanisms of the word blindness suggestion. Although the current results did not unravel the mystery of the word blindness suggestion, they showed that there are multiple voluntary ways through which participants can dramatically reduce Stroop interference.
The Taxicab: Neglected Form of Public Transportation

description: Until recently, the taxicab has been largely ignored by transportation planners as an important mode of urban public transportation. A comparison of the taxi industry with the other modes of urban public transport shows that in 1970 taxicabs produced more revenue than bus and rail operations together, carried more passengers than the rapid rail and over half as many as buses. Taxicabs traveled more than twice as many vehicle miles as buses and rapid rail combined, and did this all without benefit of public subsidy. In many small and medium-sized cities the taxicab is the only form of public transportation. In North Carolina, all of the forty-two cities with populations greater than 10,000 have taxicab service, while only thirteen of these cities have bus service. There are at least three important reasons why transportation planners and city officials should be interested in taxis. First, the demand­-responsive, flexible nature of taxi service makes it an ideal means of providing mobility for those who cannot or do not drive or who lack the use of an automobile. Second, the taxi provides low-cost service that makes it an attractive alternative to deficit-plagued bus systems. Third, as of October, 1975, taxis are eligible for federal subsidies through the 1974 National Mass Transportation Assistance Act, under the same conditions as privately-owned transit operations.

description: Characterisation protocols have so far played a central role in the development of noisy intermediate-scale quantum (NISQ) computers capable of impressive quantum feats. This trajectory is expected to continue in building the next generation of devices: ones that can surpass classical computers for particular tasks -- but progress in characterisation must keep up with the complexities of intricate device noise. A missing piece in the zoo of characterisation procedures is tomography which can completely describe non-Markovian dynamics over a given time frame. Here, we formally introduce a generalisation of quantum process tomography, which we call process tensor tomography. We detail the experimental requirements, construct the necessary post-processing algorithms for maximum-likelihood estimation, outline the best-practice aspects for accurate results, and make the procedure efficient for low-memory processes. The characterisation is a pathway to diagnostics and informed control of correlated noise. As an example application of the hardware-agnostic technique, we show how its predictive control can be used to substantially improve multi-time circuit fidelities on superconducting quantum devices. Our methods could form the core for carefully developed software that may help hardware consistently pass the fault-tolerant noise threshold.

description: Few can argue about the transformative and profound impact of gentrification on the postwar American urban landscape. While academic journals and newspaper editorials continue to swell with contrasting pieces on the blessings and/or ills of this “back to the city” urbanism, Suleiman Osman’s brilliant The Invention of Brownstone Brooklyn steers clear of making any sort of explicit value judgment. While Osman’s work is ostensibly an urban history of gentrification in New York City’s most populous borough, the true subject is not the place, but the characters that give it life. In teasing out the attitudes, convictions, and values of the gentrifiers, or “brownstoners,” and the many times contradictory impulses that drove them to recreate and “reimagine” a forgotten urban landscape, Osman creates a truly memorable and powerful piece of scholarship.

description: For a finite abelian p-group A of rank d, we define its (logarithmic) mean exponent to be the base-p logarithm of the d-th root of its cardinality. We study the behavior of the mean exponent of p-class groups in towers of number fields. By combining techniques from group theory with the Tsfasman-Valdut generalization of the Brauer-Siegel Theorem, we construct infinite tamely ramified towers in which the mean exponent of class groups remains bounded. Several explicit examples with p=2 are given. We introduce an invariant M(G) attached to a finitely generated FAb pro-p group G which measures the asymptotic growth of the mean exponent of abelianizations of subgroups of index n with n going to infinity. When G=Gal(L/K), M(G) measures the asymptotic behavior of the mean exponent of class groups in L/K. We compare and contrast the behavior of this invariant in analytic versus non-analytic groups. We exploit the interplay of group-theoretical and number-theoretical perspectives on this invariant and explore some open questions that arise as a result, which may be of independent interest in group theory.

description: Coloring unit-disk graphs efficiently is an important problem in the global and distributed setting, with applications in radio channel assignment problems when the communication relies on omni-directional antennas of the same power. In this context it is important to bound not only the complexity of the coloring algorithms, but also the number of colors used. In this paper, we consider two natural distributed settings. In the location-aware setting (when nodes know their coordinates in the plane), we give a constant time distributed algorithm coloring any unit-disk graph $G$ with at most $4ω(G)$ colors, where $ω(G)$ is the clique number of $G$. This improves upon a classical 3-approximation algorithm for this problem, for all unit-disk graphs whose chromatic number significantly exceeds their clique number. When nodes do not know their coordinates in the plane, we give a distributed algorithm in the LOCAL model that colors every unit-disk graph $G$ with at most $5.68ω(G)+1$ colors in $O(\log^* n)$ rounds. This algorithm is based on a study of the local structure of unit-disk graphs, which is of independent interest. We conjecture that every unit-disk graph $G$ has average degree at most $4ω(G)$, which would imply the existence of a $O(\log n)$ round algorithm coloring any unit-disk graph $G$ with (approximately) $4ω(G)$ colors in the LOCAL model. We provide partial results towards this conjecture using Fourier-analytical tools.

description: Query formulation is increasingly performed by systems that need to guess a user's intent (e.g. via spoken word interfaces). But how can a user know that the computational agent is returning answers to the "right" query? More generally, given that relational queries can become pretty complicated, how can we help users understand existing relational queries, whether human-generated or automatically generated? Now seems the right moment to revisit a topic that predates the birth of the relational model: developing visual metaphors that help users understand relational queries. This lecture-style tutorial surveys the key visual metaphors developed for visual representations of relational expressions. We will survey the history and state-of-the art of relationally-complete diagrammatic representations of relational queries, discuss the key visual metaphors developed in over a century of investigating diagrammatic languages, and organize the landscape by mapping their used visual alphabets to the syntax and semantics of Relational Algebra (RA) and Relational Calculus (RC).

description: We optimize a selection of eigenvalues of the Laplace operator with Dirichlet or Neumann boundary conditions by adjusting the shape of the domain on which the eigenvalue problem is considered. Here, a phase-field function is used to represent the shapes over which we minimize. The idea behind this method is to modify the Laplace operator by introducing phase-field dependent coefficients in order to extend the eigenvalue problem on a fixed design domain containing all admissible shapes. The resulting shape and topology optimization problem can then be formulated as an optimal control problem with PDE constraints in which the phase-field function acts as the control. For this optimal control problem, we establish first-order necessary optimality conditions and we rigorously derive its sharp interface limit. Eventually, we present and discuss several numerical simulations for our optimization problem.

description: Idiopathic normal pressure hydrocephalus (iNPH) is a disorder of older adults characterized by gait disturbance, dementia, and urinary incontinence combined with cerebral ventricular enlargement and normal cerebrospinal fluid pressure. Diagnosis is a clinical challenge, as typical symptoms are commonly present in other disorders of older age. Gait improvement after a diagnostic cerebrospinal fluid drain is a key determinant of probable iNPH; however, the definition of gait improvement remains unknown. Our scoping review will map existing data on quantitatively measured gait parameters in patients with iNPH, as well as the direction and magnitude of change in gait parameters before and after cerebrospinal fluid drainage. This protocol delineates the project, aims, methodology and search strategies of the scoping review.
How Tarboro Won the Public/Private Game
Creators: name: Faust, Ginny

Year: 1982

description: A walk in Tarboro is not what you'd expect. No decaying, rundown downtown in this small southern community. It has its empty storefronts, but a poster on the door of one vacant building is indicative of the real story in this town. The poster announces a candlelight tour of the community's historic homes followed by a special concert of seasonal music, and asks interested residents to call Watson or Phil at Tour Headquarters. Tour Headquarters turns out to be the Tarboro Planning department, and Watson Brown and Phil Guy are two of the planning staff. They're the same people who helped purchase that vacant building, along with several other downtown properties, with a $2.7 million Urban Development Action Grant for downtown revitalization projects. Another sign announces "The Great Downtown Tarboro Attic Sale," which was held to raise money for restoring the Blount-Bridgers House, a historic landmark. It will contain an art gallery and community center. Interested in further information? Once again, the sign tells you to call the planning department. Caroling Planning traveled to Tarboro to interview planning director Watson Brown about Tarboro 's transition from reliance on federal funding to experimentation with public/private ventures.
Reliable lattice dynamics from an efficient density functional

description: First principles predictions of lattice dynamics are of vital importance for a broad range of topics in materials science and condensed matter physics. The large-scale nature of lattice dynamics calculations and the desire to design novel materials with distinct properties demands that first principles predictions are accurate, transferable, efficient, and reliable for a wide variety of materials. In this work, we demonstrate that the recently constructed r2SCAN density functional meets this need for general systems by demonstrating phonon dispersions for typical systems with distinct chemical characteristics. The functional's performance opens a door for phonon-mediated materials discovery from first principles calculations.

description: A quantum field theory in its algebraic description may admit many irregular states. So far, selection criteria to distinguish physically reasonable states have been restricted to free fields (Hadamard condition) or to flat spacetimes (e.g. Buchholz-Wichmann nuclearity). We propose instead to use a modular l^p-condition, which is an extension of a strengthened modular nuclearity condition to generally covariant theories. The modular nuclearity condition was previously introduced in Minkowski space, where it played an important role in constructive two dimensional algebraic QFT's. We show that our generally covariant extension of this condition makes sense for a vast range of theories, and that it behaves well under causal propagation and taking mixtures. In addition we show that our modular l^p-condition holds for every quasi-free Hadamard state of a free scalar quantum field (regardless of mass or scalar curvature coupling). However, our condition is not equivalent to the Hadamard condition.

Reflections on the Low Income Housing Issue (Commentary)
Creators: name: Stegman, Michael A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1985

description: Between fiscal years 1979 and 1986, the low income housing sector has borne the brunt of the "Reagan revolution." During this time, annual funding for low income housing programs declined by more than twothirds in current dollars (from $32 billion a year to $9.9 billion), and by three-quarters in inflation-adjusted dollars. Housing advocates across the country have been numbed by these draconian cuts in low income housing programs, by repeated Administration claims that housing resources are best produced and allocated through the market mechanisms, and by government plans to privatize the FHA and get out of the housing business. Not surprisingly, much of the energies of these housing advocates have been devoted to preserving whatever programs they can rather than systematically rethinking what an appropriate federal housing role should be in the contemporary policy environment. What creative thinking is taking place among low-income housing advocates tends to be premised on the need for an even greater federal commitment to low income housing than existed either before the Reagan victory or during the 1960s, the height of liberal housing policy-making and program implementation. Rather than addressing the more practical and difficult issues of how increasingly scarce federal housing resources should be strategically allocated among a number of competing uses, housing advocates behave as if a Democratic administration in 1988 would eagerly embrace their ambitious housing agenda. Unfortunately, this is just wishful thinking.
Hessian characterization of a vortex in a maze

description: Recent advances in vortex imaging allow for tracing the position of individual vortices with high resolution. Pushing an isolated vortex through the sample with the help of a controlled $dc$ transport current and measuring its local $ac$ response, the pinning energy landscape could be reconstructed along the vortex trajectory [$\text{L. Embon } et\ al.$, $\text{Scientific Reports}$ $\mathbf{5}$, $7598$ $(2015)$]. This setup with linear tilts of the potential landscape reminds about the dexterity game where a ball is balanced through a maze. The controlled motion of objects through such tilted energy landscapes is fundamentally limited to those areas of the landscape developing local minima under appropriate tilt. We introduce the Hessian stability map and the Hessian character of a pinning landscape as new quantities to characterize a pinning landscape. We determine the Hessian character, the area fraction admitting stable vortex positions, for various types of pinning potentials: assemblies of cut parabolas, Lorentzian- and Gaussian-shaped traps, as well as a Gaussian random disordered energy landscape, with the latter providing a universal result of $(3-\sqrt{3})/6 \approx 21\%$ of stable area. Furthermore, we discuss various aspects of the vortex-in-a-maze experiment.

description: Markovianity lies at the heart of communication problems. This in turn makes the information-theoretic characterization of Markov processes worthwhile. Data processing inequalities are ubiquitous in this sense, assigning necessary conditions for all Markov processes. We address here the problem of the information-theoretic analysis of constraints on Markov processes in the quantum regime. We show the existence of a novel class of quantum data processing inequalities called here quantum Markov monogamy inequalities. This new class of necessary conditions on quantum Markov processes is inspired by its counterpart for classical Markov processes, and thus providing a strong link between classical and quantum constraints on Markovianity. We go on to construct a family of multitime quantum Markov monogamy inequalities, based on the process tensor formalism and that exploits multitime correlations. We then show, by means of an explicit example, that the Markov monogamy inequalities can be stronger than the usual quantum data processing inequalities.

description: Finding the name of an unknown symbol is often hard, but writing the symbol is easy. This bachelor's thesis presents multiple systems that use the pen trajectory to classify handwritten symbols. Five preprocessing steps, one data augmentation algorithm, five features and five variants for multilayer Perceptron training were evaluated using 166898 recordings which were collected with two crowdsourcing projects. The evaluation results of these 21 experiments were used to create an optimized recognizer which has a TOP1 error of less than 17.5% and a TOP3 error of 4.0%. This is an improvement of 18.5% for the TOP1 error and 29.7% for the TOP3 error.
