description: We explore the cosmological implications of a mechanism found in several approaches to quantum-gravity, whereby the spectral dimension of spacetime runs from the standard value of 4 in the infrared (IR) to a smaller value in the ultraviolet (UV). Specifically, we invoke the picture where the phenomenon is associated with modified dispersion relations. With minimal assumptions, we find that UV behaviour leading to 2 spectral dimensions results in an exactly scale-invariant spectrum of vacuum scalar and tensor fluctuations, regardless of the equation of state. The fluctuation production mechanism is analogous to the one known for varying speed of sound/light models and, unlike in inflation, the spectrum is already scale-invariant before leaving the horizon, remaining so after freeze-in. In the light of Planck's recent results we also discuss scenarios that break exact scale-invariance, such as the possibility that the spectral dimension runs down to a value slightly higher than 2, or runs down to 2 but with an extremely slow transient. We further show that the tensor to scalar ratio is fixed by the UV ratio between the speed of gravity and the speed of light. Not only does our model not require inflation, but at its most minimal it seems incompatible with it. In contrast, we find that running spectral dimensions can improve the outlook of the cyclic/ekpyrotic scenario, solving the main problems present in its simplest and most appealing realisations.

The immanent American fantastic: immanence and liminality in contemporary U.S. fantastic literature
Creators: name: Ciccolo, Drew J.
Publisher: name: No Publisher Supplied
Year: 2022

description: This dissertation is a study of “the American fantastic,” i.e. the literary fantastic in an American context. I suggest that conceiving of the fantastic in the context of Gilles Deleuze’s and Félix Guattari’s philosophy of immanence productively supersedes more common, dyadic conceptualizations of the fantastic, and that this dissolving of traditional binaries appears to be the next logical step in the the way we think about the fantastic. Using this conceptual framework, I analyze three particularly resonant, contemporary fantastic U.S. novels: Toni Morrison’s Beloved (1987), Rachel Ingalls’s Mrs. Caliban (1982), and Brett Easton Ellis’s American Psycho (1991). I show the ways these narratives engage with the fantastic in order to enable profound and compelling critiques of dominant U.S. social orders, from the antebellum, Civil War, and Reconstruction eras to the postwar suburbs to Reagan-era Manhattan, as well as the ways they prefigure current American social phenomena. In doing so, I locate connective themes of liminality, the return of the repressed, captivity, uniformity and alterity, and the desire for an end to evolving forms of subjugation inherent in the colonialist impetus to dehumanize and exploit for wealth and power, which these novels arguably depict as not just destructive, but self-destructive.

description: The reinforcement of light metal components with steel allows to increase the strength of the part while keeping the weight comparatively low. Lateral angular co-extrusion (LACE) offers the possibility to produce hybrid coaxial profiles consisting of steel and aluminum. In the present study, the effect of the process parameters temperature, contact pressure and time on the metallurgical bonding process and the development of intermetallic phases was investigated. Therefore, an analogy experiment was developed to reproduce the process conditions during co-extrusion using a forming dilatometer. Based on scanning electron microscopy analysis of the specimens, the intermetallic phase seam thickness was measured to calculate the resulting diffusion coefficients. Nanoindentation and energy dispersive X-ray spectroscopy measurements were carried out to determine the element distribution and estimate properties within the joining zone. The proposed numerical model for the calculation of the resulting intermetallic phase seam width was implemented into a finite element (FE) software using a user-subroutine and validated by experimental results. Using the subroutine, a numerical prediction of the resulting intermetallic phase thicknesses is possible during the tool design, which can be exploited to avoid the weakening of the component strength due to formation of wide intermetallic phase seams. © 2020 by the authors.

description: The characterization of network community structure has profound implications in several scientific areas. Therefore, testing the algorithms developed to establish the optimal division of a network into communities is a fundamental problem in the field. We performed here a highly detailed evaluation of community detection algorithms, which has two main novelties: 1) using complex closed benchmarks, which provide precise ways to assess whether the solutions generated by the algorithms are optimal; and, 2) A novel type of analysis, based on hierarchically clustering the solutions suggested by multiple community detection algorithms, which allows to easily visualize how different are those solutions. Surprise, a global parameter that evaluates the quality of a partition, confirms the power of these analyses. We show that none of the community detection algorithms tested provide consistently optimal results in all networks and that Surprise maximization, obtained by combining multiple algorithms, obtains quasi-optimal performances in these difficult benchmarks.

The Undergraduate Survey Course as an Introduction to Planning
Creators: name: Hankins, Wes
name: Hibbard, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: There has been a rising interest in undergraduate planning education in recent years. A basic indicator of this trend is the growing number of undergraduate programs. Successive editions of the Guide to Undergraduate Education in Urban and Regional Planning document this. The second edition of the Guide (Hankins et al. 1988) lists thirty-four programs that award undergraduate degrees in planning and an additional eighteen non-degree programs. Three years later, the third edition (Hankins et al. 1991) lists thirty-seven undergraduate degree-granting planning programs, fourteen "planning-related" undergraduate degree-granting programs, and twenty-two non-degree programs. Probably a more engaging indicator for most academics is the recent flowering of dialogue on the nature, purpose, and feasibility of undergraduate planning education The Report of the Commission on Undergraduate Education of the Association of Collegiate Schools of Planning (ACSP) (Niebanck et al., 1990), also called the Niebanck Report, has stimulated much discussion at ACSP's annual meetings, and there have been several recent pieces in the Journal of Planning Education and Research (Goldsmith 1991. Hotchkiss 1992. Goldsmith 1992, Niebanck 1992, Dalton and Hankins 1993). One part of the dialogue revolves around how undergraduate planning education is to be conceptualized. The issue can be roughly stated in the following two questions: 1) Is professional planning education possible and appropriate at the undergraduate level? 2) Are there goals for undergraduate planning education other than preparation for professional practice?

description: The fabrication of accentuated gold microstructures is demonstrated by multi-photon photoreduction inside an anionic fluorophore-containing hydrogel. We attempted to facilitate gold-ion photoreduction near the focal point of laser pulses, expecting the donation of electrons by the oxidation of fluorophores in the vicinity of gold ions. The presence of anionic FITCdextran also inhibited the spontaneous reduction in untargeted zones, which is attributed to the coordination of gold ions and the anionic FITC-dextran. Simultaneous facilitation and inhibition are promising for the fabrication of dense metal microstructures in the targeted zone while maintaining the hydrogel's light permeability. © 2020 Optical Society of America.

description: The Polonyi field is a necessary ingredient in any viable scenario of gravity mediated supersymmetry breaking. However, it is known that the presence of the Polonyi field leads to several serious cosmological problems, which are collectively referred to as the Polonyi problem. We show that the Polonyi problem can be solved if the Polonyi field couples to a pseudo modulus in the superpotential and this pseudo modulus has a large field expectation value during inflation. To illustrate our idea, we construct an explicit model which can be readily connected to scenarios of gravity mediation. The generation of the mass parameters contained in our model by strong gauge dynamics is also commented on.

Entre los pros y contras a raíz de la propuesta del ministro Juan Fernando Cristo, se destaca la preocupación por el elevado índice de abstencionismo[1]que, por cierto, es un problema común a la mayoría de los países con un régimen de elecciones periódicas. Lo que no deja de sorprender de los argumentos esgrimidos a favor de la propuesta es que, en buena medida, provengan de quienes se han beneficiado de dichas elecciones, es decir, delos políticos de profesión. Y no sorprende precisamente porque es un debate que se remonta a los orígenes mismos de nuestras repúblicas, pues el derecho al voto nació como una preocupación de las corporaciones de delegados que decían representar al “pueblo”, la “nación”, el “reino” o la “patria

description: Nearby gamma-ray bursts (GRBs) are likely to have represented a significant threat to life on the Earth. Recent observations suggest that a significant source of such bursts is compact binary mergers in globular clusters. This link between globular clusters and GRBs offers the possibility to find time intervals in the past with higher probabilities of a nearby burst, by tracing globular cluster orbits back in time. Here we show that the expected flux from such bursts is not flat over the past 550 Myr but rather exhibits three broad peaks, at 70, 180 and 340 Myr ago. The main source for nearby GRBs for all three time intervals is the globular cluster 47 Tuc, a consequence of its large mass and high stellar encounter rate, as well as the fact that it is one of the globular clusters which comes quite close to the Sun. Mass extinction events indeed coincide with all three time intervals found in this study, although a chance coincidence is quite likely. Nevertheless, the identified time intervals can be used as a guide to search for specific signatures of GRBs in the geological record around these times.

description: With the recent measurement of $Z_b(10610)$ and $Z_b(10650)\to B\bar{B}^*+c.c.$ and $B^*\bar{B}^*$, we investigate the transitions from the $Z_b(10610)$ and $Z_b(10650)$ to bottomonium states with emission of a pion via intermediate $B \ {B}^*$ meson loops. The experimental data can be reproduced in this approach with a commonly accepted range of values for the form factor cutoff parameter $α$. The $Υ(3S)π$ decay channels appear to experience obvious threshold effects which can be understood by the property of the loop integrals. By investigating the $α$-dependence of partial decay widths and ratios between different decay channels, we show that the intermediate $B \ {B}^*$ meson loops are crucial for driving the transitions of $Z_b/Z_b'\to Υ(nS)π$ with $n = 1, 2, 3$, and $h_b(mP)π$ with $m = 1$ and 2.

description: The time-averaged velocity profile of a turbulent boundary layer can be predicted combining its different trends in the inner and outer regions in a single law of the wake. A new non- dimensional coordinate system that projects the time-averaged velocity profiles of the inner and the outer regions on the same non-dimensional plane is introduced, leading to a unified treatment for the mixing region. In this coordinate system, various laws of the wake are shown to be the same but a constant. The non-dimensionalization is tested on a specific law of the wake, in which the closure coefficients are regressed from wind tunnel measurements and direct numerical simulations of turbulent boundary layers under zero-pressure gradient, over a good range of boundary layer thickness based Reynolds numbers. This data fit produced profiles within 2% of the reference values. This is of practical use to numerical modellers for generating boundary layer inflow profiles.

description: Detailed knowledge of the mesopheric sodium layer characteristics is crucial to estimate and optimize the performance of Laser Guide Star (LGS) assisted Adaptive Optics (AO) systems. In this paper, we present an analysis of two sets of data on the mesospheric sodium layer. The first set comes from a laser experiment that was carried out at Cerro Tololo to monitor the abundance and altitude of the mesospheric sodium in 2001, during six runs covering a period of one year. This data is used to derive the mesospheric sodium column density, the sodium layer thickness and the temporal behavior of the sodium layer mean altitude. The second set of data was gathered during the first year of the Gemini MCAO System (GeMS) commissioning and operations. GeMS uses five LGS to measure and compensate for atmospheric distortions. Analysis of the LGS wavefront sensor data provides information about the sodium photon return and the spot elongation seen by the WFS. All these parameters show large variations on a yearly, nightly and hourly basis, affecting the LGS brightness, shape and mean altitude. The sodium photon return varies by a factor of three to four over a year, and can change by a factor of two over a night. In addition, the comparison of the photon returns obtained in 2001 with those measured a decade later using GeMS shows a significant difference in laser format efficiencies. We find that the temporal power spectrum of the sodium mean altitude follows a linear trend, in good agreement with the results reported by Pfrommer & Hickson (2010).

description: An alternative proof of Lie's approach for linearization of scalar second order ODEs is derived using the relationship between $λ$-symmetries and first integrals. This relation further leads to a new $λ$-symmetry linearization criteria for second order ODEs which provides a new approach for constructing the linearization transformations with lower complexity. The effectiveness of the approach is illustrated by obtaining the local linearization transformations for the linearizable nonlinear ODEs of the form $y''+F_1(x,y)y'+F(x,y)=0$. Examples of linearizing nonlinear ODEs which are quadratic or cubic in the first derivative are also presented.
Where to Draw the Line: Using GIS to Incorporate Environmental Data in Highway Placement Decisions
Creators: name: Burdick, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: One of the most difficult responsibilities of local elected officials is the approval of a thoroughfare plan for an urban area. A thoroughfare plan is a comprehensive, long-range (ten- to twenty-year) plan for highway improvements, and thus has enduring and far-reaching policy implications. When considering a thoroughfare plan, elected officials are often concerned because they cannot look at a proposed thoroughfare, represented by a line on a map, and assess the magnitude of environmental and social consequences of the route. As a result, some crucial facilities might be left off the thoroughfare plan completely, rather than risk these unknown consequences. The decision of whether to include a proposed road on a thoroughfare plan will always be difficult. However, technology is available that can help decision makers determine that a line on a map is indeed the most appropriate location for a thoroughfare. In recent years, transportation professionals and elected officials have begun to use geographic information systems (GIS) to visualize the environmental and social impacts of a corridor and to enhance their ability to choose the best route.

description: Solving large traveling salesman problem (TSP) in an efficient way is a challenging area for the researchers of computer science. This paper presents a modified version of the ant colony system (ACS) algorithm called Red-Black Ant Colony System (RB-ACS) for the solutions of TSP which is the most prominent member of the combinatorial optimization problem. RB-ACS uses the concept of ant colony system together with the parallel search of genetic algorithm for obtaining the optimal solutions quickly. In this paper, it is shown that the proposed RB-ACS algorithm yields significantly better performance than the existing best-known algorithms.

Governing by the numbers: quantification and the mechanisms of democracy
Creators: name: Holly, Matthew Francis
Publisher: name: No Publisher Supplied
Year: 2022

description: This project asserts that social measurement and quantification practices dictate the functional boundaries of democracy at all levels of governance. Beginning with an observation that numbers and politics have a mutually constitutive relationship, it explores how statistical actor-networks and the social relations within them interact with the political world to affect the operability of democracy. Research and analyses in this dissertation are executed with a multi-step methodology. It first presents a historiography of the confluence of statistics and governance as well as a synthesis of numerous theoretical approaches to understanding this relationship. This is then used to construct a conceptual framework for a series of case studies that reveal this relationship at work at the national, supranational, and global levels of democratic governance. The dissertation concludes that the techniques and technologies used by quantifying institutions have a profound downstream effect on the practice of democracy, arguing that the interactions between institutional, social, and political actors in these networks effectively set the limits of democratic governance.

Year: 2013
Subjects: subject: Performance (cs.PF)
subject: FOS: Computer and information sciences

description: This paper presents a systematic approach to the complex problem of high confidence performance assurance of high performance architectures based on methods used over several generations of industrial microprocessors. A taxonomy is presented for performance assurance through three key stages of a product life cycle-high level performance, RTL performance, and silicon performance. The proposed taxonomy includes two components-independent performance assurance space for each stage and a correlation performance assurance space between stages. It provides a detailed insight into the performance assurance space in terms of coverage provided taking into account capabilities and limitations of tools and methodologies used at each stage. An application of the taxonomy to cases described in the literature and to high performance Intel architectures is shown. The proposed work should be of interest to manufacturers of high performance microprocessor/chipset architectures and has not been discussed in the literature.

Local Inclusionary Housing Programs and the Prospects for North Carolina
Creators: name: Blum, Lanier
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2001

description: Many of the nation's rapidly growing communities are confronting an ironic paradox — the stronger the local economy, the more acute the shortage of affordable housing. This is certainly true of North Carolina's metropolitan areas. Generations of public investments in highways, schools, community facilities and services, universities, research, industrial recruitment, and hospitals have created a great deal of the value of urban/suburban land and generated tremendous wealth and rapid growth in this state's metropolitan areas. But every year, more of the people who keep these services and institutions operating cannot afford to live near their jobs. Moreover, in rapidly growing communities like the Triangle, powerful market incentives encourage builders to produce high-cost homes. The combination of regulatory, public investment, and market factors has resulted in a dramatically expanding affordability gap for households with low- and moderate incomes. What can local governments do to encourage the development of lower cost homes throughout these growing communities in North Carolina?

description: Few small cities have attempted—and still fewer have succeeded—in straddling both agricultural and corporate branding. Over the course of the 20th century, and with particular agility in the last two decades, Wilson has managed to attract and retain financial, pharmaceutical and technology-based industries while remaining in the forefront of regional tobacco marketing. While its agricultural connections have perhaps undergone the most drastic changes as a result of a globalized and politically-transformed market, the inroads Wilson has made in strategically pursuing other sectors have been no less remarkable or significant for the city’s economic prospects.

description: This paper investigates the nature of the development of two-dimensional laminar flow of an incompressible fluid at the reversed stagnation-point. ". In this study, we revisit the problem of reversed stagnation-point flow over a flat plate. Proudman and Johnson (1962) first studied the flow and obtained an asymptotic solution by neglecting the viscous terms. This is no true in neglecting the viscous terms within the total flow field. In particular it is pointed out that for a plate impulsively accelerated from rest to a constant velocity V0 that a similarity solution to the self-similar ODE is obtained which is noteworthy completely analytical.

description: Recent developments in medical robotics have been significant, supporting the minimally invasive operation requirements, such as smaller devices and more feedback available to surgeons. Nevertheless, the tactile feedback from a catheter or endoscopic type robotic device has been restricted mostly on the tip of the device and was not aimed to support the autonomous movement of the medical device during operation. In this work, we design a robotic sheath/sleeve with a novel and more comprehensive approach, which can function for whole body or segment-based feedback control as well as diagnostic purposes. The robotic sleeve has several types of piezo-resistive pressure and extension sensors, which are embedded at several latitudes and depths of the silicone substrate. The sleeve takes the human skin as a biological model for its structure. It has a better tactile sensation of the inner tissues in the torturous narrow channels such as cardiovascular or endoluminal tracts in human body and thus can be used to diagnose abnormalities. In addition to this capability, using the stretch sensors distributed alongside its body, the robotic sheath/sleeve can perceive the ego-motion of the robotic backbone of the catheter and can act as a position feedback device. Because of the silicone substrate, the sleeve contributes toward safety of the medical device passively by providing a compliant interface. As an active safety measure, the robotic sheath can sense blood clots or sudden turns inside a channel and by modifying the local trajectory and can prevent embolisms or tissue rupture. In the future, advanced manufacturing techniques will increase the capabilities of the tactile robotic sleeve. © The Author(s) 2020.

description: Die vorliegende Arbeit beschreibt den Einsatz von wissensbasierten Systemen (Expertensystemen) zur Modellierung und Darstellung von Fachwissen im Bereich Gartenbautechnik. Im einzelnen wurde untersucht, inwieweit die Methoden zur Entwicklung von Expertensystemen im Bereich der Gartenbautechnik eingesetzt werden können, inwieweit sie angepaßt werden müssen oder inwieweit sie eine Erweiterung konventioneller Modellierung ermöglichen. Wissensbasierte Systeme werden dabei als Computerprogramme verstanden, bei denen eine strikte Trennung zwischen einer Wissensbasis und einem Ableitungsmechanismus funktioniert.

description: We study the acoustic emission avalanches during the failure process of porous alumina samples (Al2O3) under compression. Specimens with different porosities ranging from 30% to 59% have been synthetized from a mixture of fine-grained alumina and graphite. The compressive strength as well as the characteristics of the acoustic activity have been determined. The statistical analysis of the recorded acoustic emission pulses reveals, for all porosities, a broad distribution of energies with a fat tail, compatible with the existence of an underlying critical point. In the region of 35%-55% porosity, the energy distributions of the acoustic emission signals are compatible with a power law behavior over two decades in energy with an exponent ε= 1.8+/-0.1.

description: L'enseignement supérieur à distance constitue un grand défi à l'ère actuelle. La transition vers ce mode d'enseignement, suite aux situations de crises (COVID 19) ou aux volontés des états, constitue un clivage important dans le domaine dont il faut maitriser les résultats. La performance de l'enseignement à distance constitue ainsi une problématique d'actualité.
L'objectif de cette recherche est de développer un outil de mesure permettant d'évaluer la performance de l'enseignement à distance, ce qui permettra de quantifier son niveau tout en identifiant les dimensions essentielles qui impactent cette performance de manière significative.
L'échelle est ensuite affinée grâce à un test pilote, visant à évaluer la pertinence et la clarté des questions. Une enquête plus large est ensuite menée auprès d'un échantillon représentatif de 87 étudiants de l'université Mohammed Premier d'Oujda pour collecter les données nécessaires à la validation de l'échelle.

description: In this paper, a canonical ensemble model for the black hole quantum tunneling radiation is introduced. With this model the probability distribution function corresponding to the emission shell is calculated. Comparing with this function, the statistical significance of the quantum tunneling radiation spectrum of black holes is investigated. Moreover, by calculating the entropy of the emission shell, a discussion about the mechanism of information flowing out from the black hole is given too.

Ese momento de gloria y orgullo para cada estudiante que, después de haber pasado por Ciencias Básicas, Clínicas y el Internado, años de abnegado servicio, llega a ser la cereza en el pastel y coronar ese camino que tanto trabajo costó recorrer
The spin-polarized $ν=0$ state of graphene: a spin superconductor

description: We study the spin-polarized $ν=0$ Landau-level state of graphene. Due to the electron-hole attractive interaction, electrons and holes can bound into pairs. These pairs can then condense into a spin-triplet superfluid ground state: a spin superconductor state. In this state, a gap opens up in the edge bands as well as in the bulk bands, thus it is a charge insulator, but it can carry the spin current without dissipation. These results can well explain the insulating behavior of the spin-polarized $ν=0$ state in the recent experiments.
