description: A generalized description of entanglement and quantum correlation properties constraining internal degrees of freedom of Dirac(-like) structures driven by arbitrary Poincaré classes of external field potentials is proposed. The role of (pseudo)scalar, (pseudo)vector and tensor interactions in producing/destroying intrinsic quantum correlations for $\mbox{SU}(2) \otimes \mbox{SU}(2)$ bi-spinor structures is discussed in terms of generic coupling constants. By using a suitable ansatz to obtain the Dirac Hamiltonian eigenspinor structure of time-independent solutions of the associated Liouville equation, the quantum entanglement, via concurrence, and quantum correlations, via geometric discord, are computed for several combinations of well-defined Poincaré classes of Dirac potentials. Besides its inherent formal structure, our results setup a framework which can be enlarged as to include localization effects and to map quantum correlation effects into Dirac-like systems which describe low-energy excitations of graphene and trapped ions.

description: Many decisions must be made with incomplete information. The ability to evaluate the resulting uncertainty is a key aspect of metacognition. As both confidence judgments and reaction times are expected to be closely related to sensory uncertainty, a mathematical model of human perceptual decision-making should be able to explain them both. We propose the new dynamical evidence and visibility model, an extension of the popular drift diffusion model of decision making, to account for choices, reaction times and confidence at the same time. We compare model fits of the dynamical evidence and visibility model with the two-stage dynamical signal detection theory and several versions of the race model of decision making.
Residential valuation of streams in Wake County, N.C.
Creators: name: Glober, Denman
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: This paper investigates the effects of stream presence, type, and amount of streamflow on residential property prices in Wake County, North Carolina, sold in 2004. The choice of topic was informed by a rising awareness of water scarcity in the Eastern United States and the growing popularity of market based methods for controlling public goods such as instream water. This paper employs hedonic price modeling, one method of pricing analysis which has not before been applied to the problem of instream flow. This paper finds that stream flow does matter to residential property owners as expressed by a strong preference for perennial streams (streams with year round flows) over intermittent streams (streams that run dry for parts of the year). This indicates that home prices in Wake County will fall if perennial streams become intermittent due to groundwater depletion or development.
Generalized quantum Fokker-Planck equation for photoinduced nonequilibrium processes with positive definiteness condition
Creators: name: Jang, Seogjoo
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This work provides a detailed derivation of a generalized quantum Fokker-Planck equation (GQFPE) appropriate for photo-induced quantum dynamical processes. The path integral method pioneered by Caldeira and Leggett (CL) [Caldeira and Leggett, Physica A 121, 587 (1983)] is extended for a nonequilibrium influence functional, which has been obtained for general cases where the ground and the excited electronic state baths can be different. Both nonequilibrium and non-Markovian effects are accounted for consistently by expanding the paths in the exponents of the influence functional with respect to time up to the second order. This procedure results in approximations involving only single time integrations for the exponents of the influence functional but with additional time dependent boundary terms that have been ignored in previous works. The boundary terms complicate the derivation of a time evolution equation, but do not affect position dependent physical observables or the dynamics in the steady state limit. For an effective density operator with the boundary terms factored out, a time evolution equation is derived through short time expansion of the effective action followed by Gaussian integrations in analytically continued complex domain of space. This leads to a compact form of GQFPE with time dependent kernels and additional terms, which make the resulting equation the Dekker form [H. Dekker, Phys. Rep. 80, 1 (1981)]. Major terms of the equation are analyzed for the case of Ohmic spectral density with Drude cutoff, which shows that the new GQFPE satisfies the positive definiteness condition in medium to high temperature limit.
Adapting Participatory Research Methods to Community-Based Planning
Creators: name: Shaughnessy, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Effective planning must take a holistic perspective, a wide view of how systems interact. However, this approach can preclude an understanding of individual perspectives and lived experiences. Participatory research methods pioneered outside of the field of planning have been designed to document and address community needs and priorities at a localized level. Among these methods is photo elicitation, a mode of qualitative and visual data collection that involves having participants take photographs that portray a particular concern, and then using the images and a starting point for discussion around how to address those concerns. While photo elicitation and other CBPR methods are becoming increasingly common in fields such as sociology and public health, they are rare in the field of urban planning, despite their applicability and potential value.This paper evaluates the utility and feasibility of using photo elicitation as a tool for community planning, based on a case study of a photo project in Durham, North Carolina. The paper concludes with an evaluation of the method’s strengths and limitations in the context of community-based planning and a set of recommendations for how participatory research methods can be incorporated in future planning efforts.

description: "We teach what we research and we research what we teach!" Dieser Leitspruch der Pädagogischen Fakultät der Universität Helsinki, die ich im Frühjahr 2014 besuchen durfte, stellt auch meine Vision für unsere Hochschule dar. In den nächsten 5 bis 10 Jahren sollen die Rahmenbedingungen dafür ausgebaut werden, dass Forschung für alle Kolleginnen und Kollegen ein Thema sein kann. Zahlreiche Publikationen, Dissertations- und Habilitationsprojekte geben ein weiteres beredtes Zeugnis davon, dass an unserer Hochschule in den letzten Jahren ein forschungsorientiertes institutionelles Klima weiter ausgebaut werden konnte. Und dies bei Rahmenbedingungen und einer Ausstattung mit Forschungsressourcen, die noch alles andere als ideal sind. Wenn wir gerade in der Konzipierung der Pädagoginnen- und Pädagogenbildung davon sprechen, wie wichtig die vier Säulen sind – Fachwissenschaft, Fachdidaktik, Bildungswissenschaft und pädagogisch-praktische Studien – dann immer auf dem Hintergrund, dass Forschung in allen Bereichen Thema sein sollte – in unterschiedlichen Ausprägungen: von der Reflexion der eigenen Praxis über forschungsgeleitete Lehre bis hin zur Teilnahme am nationalen und internationalen Bildungsforschungsdiskurs. Prof. Prenzel von der School of Education der TU München ist davon überzeugt, dass es aus einer übergeordneten Perspektive nicht nur darum geht, Wissen aus der Forschung zu rezipieren und zu interpretieren, sondern mit der Forschung in einen Dialog zu treten und selbst dazu beizutragen. Forschung, zumal Bildungsforschung, hat aber keinen Selbstzweckcharakter. Forschung sollte immer auch dem Projekt der „Kultivierung der Menschlichkeit“ dienen, wie dies M. Nußbaum in ihrem gleichnamigen Buch eindrucksvoll darstellt. Die Fähigkeit kritischen Denkens – wahrscheinlich die Grundhaltung allen Forschens – sei deswegen von größter Bedeutung, um ein geprüftes Leben führen zu können – in Anlehnung an Sokrates formuliert Nußbaum »An unexamined life is not worth to be lived!« (Aus dem Vorwort von Rektor Franz Keplinger)

description: Many developing nations are currently faced with the challenge of designing and implementing transportation infrastructure and systems in the context of rapidly growing urban populations and constrained resources. Inappropriately designed transportation infrastructure has negative implications through increased emissions.1 Appropriately designed transportation infrastructure must be tailored to the unique demands of a city, and respond appropriately to the differing demands of different kinds of urban form – e.g., monocentric or polycentric, require different transport practices. Energy demands in a monocentric city are larger per capita than those in a polycentric city (Figueroa 2014), adding to increased emissions. As cities in India continue to develop, the facilitation of pedestrian and biking infrastructure may have the largest positive effect on emissions, especially in polycentric cities with several small self-supporting nodes. However, within monocentric cities, commutes are likely to be longer, in both time and distance, with a high percentage of the trips congesting the central area of the city.
With the rapid urbanization of India, there has been increasing consumption of transportation, transportation infrastructure, and natural resources. Some cities in the developing world have confronted this growth in demand through mass transit with high ridership, particularly in South America. As the cities in developing countries continue to grow, it is imperative that future infrastructure practices and policies focus on efficient methods and plans to proactively prevent the continued rise and sustained use of individual motorized vehicles (Chen 2011). The implications of comprehensive transit planning that understand the linkage between land use and transportation, will have significant effects on emissions in cities.

Working in the context of a static Bañados-Teitelboim-Zanelli (BTZ) black hole spacetime we find that it is possible to harvest tripartite entanglement in regions where harvesting of bipartite entanglement is known to be impossible due to intense Hawking radiation. In these situations, it implies that the harvested entanglement is of the Greenberger-Horne-Zeilinger (GHZ) type.

description: Muon scattering tomography (MST) is a non-destructive technique to image various materials by utilizing cosmic ray muons as probes. A typical MST system with a two-fold track detectors is particularly effective in detecting high-$Z$ materials (e.g. nuclear materials), but difficult to recognize low-$Z$ materials (e.g. explosive materials). In this work, we present a concept of MST system to discriminate both low-$Z$ and high-$Z$ materials by extra measuring momentum of low-energy muons with a Cherenkov detector. A toy Monte Carlo simulation to describe detector responses and multiple scatterings of a muon tracking through materials is developed for statistical tests. Based on momentum-dependent track reconstruction and image reconstruction algorithm, we evaluate separation powers of different materials in the system. The results show that momentum measurement of low-energy muons and accurate track reconstruction can improve separation power of low-$Z$ materials significantly. This may enable the MST system to detect both low-$Z$ and high-$Z$ materials with cosmic ray muons in the whole energy range.

description: Abstract INTRODUCTION Occupational health service (OHS) is considered an expert function when it comes to supporting workplaces in their systematic work environment management (SWEM). Scientific research shows that OHS is not used as support in preventive SWEM, but instead to support individuals when work related problems are already acquired. Since OHS is not used in preventive SWEM, the knowledge about how to conduct successful SWEM is limited. More knowledge about important implementation factors in this field is needed. OBJECTIVE The aim of this study is to increase the knowledge of how work environment interventions in healthcare settings are implemented and how this implementation affects the outcome. METHODS A systematic literature review with a narrative synthesis. DISCUSSION The results can be used as a guide for how to implement future work environment intervention studies. It can also be used as a guide to practical OHS work, how to support employers and employees in SWEM, or preventive work interventions with a systems approach. Increased knowledge and increased support within the work environment management might be of great value, benefiting employers, employees, the healthcare system and society. Key words: Occupational health service, healthcare workers, Occupational health and safety.

Entropy Estimation via Uniformization

Publisher: name: arXiv
Year: 2023
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Entropy estimation is of practical importance in information theory and statistical science. Many existing entropy estimators suffer from fast growing estimation bias with respect to dimensionality, rendering them unsuitable for high-dimensional problems. In this work we propose a transform-based method for high-dimensional entropy estimation, which consists of the following two main ingredients. First by modifying the k-NN based entropy estimator, we propose a new estimator which enjoys small estimation bias for samples that are close to a uniform distribution. Second we design a normalizing flow based mapping that pushes samples toward a uniform distribution, and the relation between the entropy of the original samples and the transformed ones is also derived. As a result the entropy of a given set of samples is estimated by first transforming them toward a uniform distribution and then applying the proposed estimator to the transformed samples. The performance of the proposed method is compared against several existing entropy estimators, with both mathematical examples and real-world applications.

description: In order to improve the particle identification capability of the Beijing Spectrometer III (BESIII),t is proposed to upgrade the current endcap time-of-flight (ETOF) detector with multi-gap resistive plate chamber (MRPC) technology. Aiming at extending ETOF overall time resolution better than 100ps, the whole system including MRPC detectors, new-designed Front End Electronics (FEE), CLOCK module, fast control boards and time to digital modules (TDIG), was built up and operated online 3 months under the cosmic ray. The main purposes of cosmic ray test are checking the detectors' construction quality, testing the joint operation of all instruments and guaranteeing the performance of the system. The results imply MRPC time resolution better than 100$ps$, efficiency is about 98$\%$ and the noise rate of strip is lower than 1$Hz/$($scm^{2}$) at normal threshold range, the details are discussed and analyzed specifically in this paper. The test indicates that the whole ETOF system would work well and satisfy the requirements of upgrade.
Contemporary Embassy Planning: Designing in an Age of Terror

Year: 2007

description: This thesis is divided into three sections. The first section will give background into the history and policies that have shaped American embassy planning. Special attention will be placed on the symbolism of the American embassies throughout history. This is important because it shows how the United States has been as deliberate as possible in putting forth a positive image of America abroad. This review also reveals the processes by which embassies where sited, and the effects of embassy placement and design on host cities. The second section considers the embassy as a particularly appealing target for terrorism and outlines the events and policies that have shaped American embassy planning in the Age of Terror. The current policies and practices of the Bureau of Overseas Building Operations, housed in the State Department will be covered including Standard Embassy Design and the Design/Build Program now in effect. The third section analyzes four embassies according to their urbanistic participation within a host city. Contemporary embassies come in two types: Embassies with great symbolic importance and embassies that are built as enclave-like compounds. The embassies analyzed include the American embassies in Dar es Salaam, Nairobi, Ottawa, Berlin, and the future embassy in Baghdad. The fourth section is a concluding discussion about the importance of the American embassy as a symbolic gesture and its importance to putting forth a positive image of America abroad. The United States embassy program is currently suffering from a severe identity crisis. Establishing an identity (whatever that identity may be) for the American embassy should be of utmost important to American diplomacy.

description: Abstract Background: An estimated 400.000 children develop cancer worldwide. Of those, 90% occur live in low- and middle-income countries, where survival rates can be as low as 30%. To reduce the childhood cancer survival gap between high- and low- and middle-income countries (LMIC), the World Health Organization launched the Global Initiative for Childhood Cancer in 2018, to support governments in building sustainable childhood cancer programs, with the aim to increase access and quality of care for children with cancer. Developing a high-quality and trained workforce is key to the success of childhood cancer services, but more information is needed on the interventions used to develop and train a workforce. The objective of this review is to understand the key factors described in the literature in relation to the development and training of a workforce in childhood cancer in LMIC, including challenges, interventions and their outcomes. Methods: We will include sources of evidence that describe the development or training of a childhood cancer workforce in health services that diagnose, refer or treat children with cancer, in low and middle-income countries as defined by the World Bank. The following databases will be searched: OVID Medline, Embase and Pubmed from 2001 to present with no restriction of language. Grey literature searches will also be performed in Proquest Dissertation and Theses, as well as relevant organizations’ websites, and conference proceedings will be searched in conference websites. In addition, references lists will be reviewed manually. Two people will screen abstracts and full-texts and extract data. Data will be presented in a table or chart, with an accompanying narrative summary responding to the review questions. A framework synthesis will be conducted: data will be charted against a framework adapted from the 2016 WHO Global Strategy for Human Resources for Heath: Workforce 2030. Discussion: This scoping review will allow to map the existing literature on workforce development in LMIC, identify potential interventions and highlight data and knowledge gaps. This constitutes a first step towards adopting successful strategies more broadly, formulating research priorities, and developing effective policies and interventions.
Higher spins from Nambu-Chern-Simons theory

description: We propose a new theory of higher spin gravity in three spacetime dimensions. This is defined by what we will call a Nambu-Chern-Simons (NCS) action; this is to a Nambu 3-algebra as an ordinary Chern-Simons (CS) action is to a Lie (2-)algebra. The novelty is that the gauge group of this theory is simple; this stands in contrast to previously understood interacting 3D higher spin theories in the frame-like formalism. We also consider the $N=8$ supersymmetric NCS-matter model (BLG theory), where the NCS action originated: Its fully supersymmetric M2 brane configurations are interpreted as Hopf fibrations, the homotopy type of the (infinite) gauge group is calculated and its instantons are classified.

Attractor Solutions in Interacting Dark Energy Models

description: We investigate a cosmological model in which dark energy, represented by a quintessential scalar field, is coupled to a dark-matter perfect fluid in the spatially flat Friedmann-Robertson-Walker Universe. This allows an energy exchange in the dark sector which could happen both at early times before recombination era or at late times. We use the coupling function $Q=γρ_{dm}\dotφ$ which is induced by conformal transforming scalar-tensor and $f(R)$ gravity theories to Einstein frame. It is argued that there is a connection between this coupling function and $Q\propto ρ_{dm}H$. A dynamical analysis is used to show that there are early- and late-time attracting solutions for which the system evolves for a wide range of initial conditions. These attractors generalize the scaling solutions which have been already found in the non-interacting case.

description: Collisionless shocks are efficient particle accelerators. At Earth, ions with energies exceeding 100 keV are seen upstream of the bow shock when the magnetic geometry is quasi-parallel, and large-scale supernova remnant shocks can accelerate ions into cosmic rays energies. This energization is attributed to diffusive shock acceleration, however, for this process to become active the ions must first be sufficiently energized. How and where this initial acceleration takes place has been one of the key unresolved issues in shock acceleration theory. Using Cluster spacecraft observations, we study the signatures of ion reflection events in the turbulent transition layer upstream of the terrestrial bow shock, and with the support of a hybrid simulation of the shock, we show that these reflection signatures are characteristic of the first step in the ion injection process. These reflection events develop in particular in the region where the trailing edge of large-amplitude upstream waves intercept the local shock ramp and the upstream magnetic field changes from quasi-perpendicular to quasi-parallel. The dispersed ion velocity signature observed can be attributed to a rapid succession of ion reflections at this wave boundary. After the ions' initial interaction with the shock, they flow upstream along the quasi-parallel magnetic field. Each subsequent wave front in the upstream region will sweep the ions back toward the shock, where they gain energy with each transition between the upstream and the shock wave frames. Within three to five gyroperiods, some ions have gained enough parallel velocity to escape upstream, thus completing the injection process.

description: We are conducting a systematic review on home cage monitoring in laboratory mice and rats. A major advantage of home cage monitoring is that the animals can be examined in their home environment, which reduces stress and allows to monitor the animals 24/7. Moreover, this approach minimizes the influence of the human presence on the animals’ behavior. Therefore, home cage-based monitoring is interesting for phenotyping in mice and rats since it may reduce data variability and improve reproducibility. In addition, it can provide a useful tool for welfare assessment. The requirements for home cage monitoring changed over the last decades driven by technology and digitalization. The goal of this systematic review is to identify these historical changes and describe the current state of the art.
Are Communities In The Triangle Ready To Do Their Fair Share? Developing a Regional Affordable Housing Strategy

description: Like many areas in the United States, North Carolina's Research Triangle region faces a growing and seemingly intractable scarcity of affordable housing. A suitable home, whether owned or rented, is out of reach for an increasing number of families. Even those families that are able to find housing are devoting a larger share of their financial resources toward their rent or mortgage. The problem is particularly acute near employment centers, such as Raleigh, Durham, and Chapel Hill. Many employees who work in these locations are unable to afford housing in the vicinity of their jobs and are forced to move to the fringes of the metropolitan area. This not only impacts their quality of life but also affects other Triangle residents in the form of increased traffic congestion, air pollution, and urban sprawl. The purpose of this paper is to explore whether implementing a fair share housing program might be an effective strategy for responding to the shortage of affordable housing in the Triangle. It argues that housing policies must be formulated at the regional level in order to overcome the parochialism of local governments in developing land use policies and ensure that the interests of the entire region are addressed. In contrast to other policies for increasing affordable housing, fair share programs emphasize the regional nature of the problem and specifically work to increase the distribution of affordable housing throughout a region. Thus, they have the potential to provide a solution to the spatial mismatch between jobs and housing that is a fundamental problem in the Triangle. In order to determine whether a fair share approach is right for the Triangle, the analysis begins with an evaluation of the experiences that other communities have had with fair share programs and summarizes some of the lessons learned about successful program design and implementation. The next section looks at whether the essential elements needed to support an effective fair share program currently exist in the Triangle. It concludes with an assessment of the region's readiness for a fair share program and suggestions for the next steps to take to move in the direction of increased regional cooperation in developing affordable housing policies in the Triangle.
Dichotomous acceleration process in one dimension: Position fluctuations

description: We study the motion of a one-dimensional particle which reverses its direction of acceleration stochastically. We focus on two contrasting scenarios, where the waiting-times between two consecutive acceleration reversals are drawn from (i) an exponential distribution and (ii) a power-law distribution $ρ(τ)\sim τ^{-(1+α)}$. We compute the mean, variance and short-time distribution of the position $x(t)$ using a trajectory-based approach. We show that, while for the exponential waiting-time, $\langle x^2(t)\rangle\sim t^3$ at long times, for the power-law case, a non-trivial algebraic growth $\langle x^2(t)\rangle \sim t^{2ϕ(α)}$ emerges, where $ϕ(α)=2$, $(5-α)/2,$ and $3/2$ for $α<1,~1<α\leq 2$ and $α>2$, respectively. Interestingly, we find that the long-time position distribution in case (ii) is a function of the scaled variable $x/t^{ϕ(α)}$ with an $α$-dependent scaling function, which has qualitatively very different shapes for $α<1$ and $α>1$. In contrast, for case (i), the typical long-time fluctuations of position are Gaussian.

description: Demand for senior housing options has increased in recent years and is projected to continue growing. Developers who recognize this trend and wish to expand their portfolios, however, should be aware that senior housing involves a level of complexity not encountered in standard real estate production. For example, some of the unique characteristics of senior housing include: provision of extensive support services, possible provision of asset management and long-term care for residents, and complex regulatory frameworks that govern development. (Andersen & Dillon, 2010) Within the realm of senior housing development, the Continuing Care Retirement Community (CCRC) has gained significant popularity in the last three decades, and is in a position to be one of the most attractive options for seniors in the future. This type of community provides a variety of housing options, contract options, amenities, and a guarantee of lifelong health care. There are currently more than 1,900 CCRCs in the nation, and that number will undoubtedly rise with the forthcoming increase in the elderly population. The intent of this project is to gain a better understanding of the factors that influence the feasibility, marketability, and viability of Continuing Care Retirement Communities, especially in North Carolina. Factors considered in this study include Neighborhood and Community Design, Management Structure and Policies, Fee Schedules and Refund Options, and Financial Health and Structure. Each of these elements has a number of variations that can greatly impact the overall development. As developers are faced with greater scrutiny by potential residents, regulators, and lenders, this knowledge will create an advantage in navigating the local market, approval process, and financial analysis. Additionally, the information provided can be used to help development regulators and officials assess the quality and feasibility of proposed projects. The methodology for this research employed qualitative analysis based on information gained from reading North Carolina Department of Insurance Disclosure Statements, interviewing executive directors and developers of the considered communities, as well as background research completed during PLAN 765 and 761 during the Fall semester of 2010. This research has been paired and compared with recently published literature, and provides both a local and national perspective of the impacts and influences of the considered business practices.
