The Essence of Universal Gravitation and the Power of Cosmic expansion
Creators: name: han, runguang

Year: 2023
Subjects: General relativity and gravitational waves

description: Based on the scientific achievements of the Big Bang Theory, quark model, Parton model and other scientific achievements, this paper proposes a new theoretical model(the polaron sea model) on the essence of universal gravity and the origin of dark matter and dark energy. Based on this model, a new formula of universal gravitation is deduced, the essence of universal gravitation is revealed, and the origin of dark matter and dark energy hypothesis is given. The new formula of universal gravitation can be converted into Newton's formula of universal gravitation. It is concluded that the gravitational constant G is a slowly changing quantity, the gravitational force of celestial bodies is limited, and may not form a real black hole, and the current total density of the universe is greater than the critical density. The new universal gravitation formula can explain the problem of rotational velocity of spiral galaxies. The theory predicts that universal gravitation can be partially shielded, and the problems of the generation of de Broglie wave and the interference of single photon (particle) double slit are related to the polaron sea.

Thou Shalt Not Suffer A Witch To Live: How the Incorporation of Sorcery into Heresy Critically Contributed to the Witch Stereotype of the Late Middle Ages
Creators: name: Harper, Kathryn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: This thesis suggests a revision to the chronology of the origins of witchcraft, per se, as opposed to maleficium. The language mobilized in the fifteenth century was not new, it will argue, but rather a reification and instantiation of language already in play during the fourteenth century and even earlier with respect to heresy. This work hopes to challenge this binary, and suggest that there is both a distinct difference between witchcraft of the earlier Middle Ages and of the later Middle Ages, but also that the critical shift occurs prior to the fifteenth century. How the witch came to be is another matter, and this thesis will suggest that first, the sorcerer had to become a heretic. The current literature has also noted the relationship between heresy and witchcraft – as Michael Bailey puts it, “the connection between witchcraft and heresy seems obvious.”  Indeed, the fact that the two are related has not escaped historians, yet this relationship seems not to have been explored explicitly. Thus, the purpose of this thesis is to examine that relationship more closely and to suggest that rather than heresy becoming more like witchcraft – a notion suggested by Cohn and Russell, among others – sorcery became heretical.

description: We study the $L\to l l' l' ν_l ν_L$ decays ($L=τ,μ$; $l,l'=μ,e$) in the Standard Model (SM) and in the effective field theory (EFT) description of the weak charged current at low energy, both for polarized and unpolarized $L$, keeping the $l,l'$ mass dependence. We clarify the discrepancy between two previous SM calculations of the decay rate improving their precision. The recent $3.5\,σ$ anomaly found in $τ\to e γ\barν_eν_τ$ could be checked using our precise prediction for the $τ\to e e e \barν_eν_τ$ decays, which shall be measured analyzing already existing data from the first generation B-factories. It is shown how measurements of the di-$l'$ mass distribution (with appropriate cuts) and $T$-asymmetries are able to reveal the corresponding lepton flavor violating (LFV) processes without neutrinos in the final state.

description: In the framework of the concordance cosmological model the first-order scalar and vector perturbations of the homogeneous background are derived in the weak gravitational field limit without any supplementary approximations. The sources of these perturbations (inhomogeneities) are presented in the discrete form of a system of separate point-like gravitating masses. The found expressions for the metric corrections are valid at all (sub-horizon and super-horizon) scales and converge at all points except at locations of the sources. The average values of these metric corrections are zero (thus, first-order backreaction effects are absent). Both the Minkowski background limit and the Newtonian cosmological approximation are reached under certain well-defined conditions. An important feature of the velocity-independent part of the scalar perturbation is revealed: up to an additive constant this part represents a sum of Yukawa potentials produced by inhomogeneities with the same finite time-dependent Yukawa interaction range. The suggested connection between this range and the homogeneity scale is briefly discussed along with other possible physical implications.

description: In this paper, we study one of the open problems in Finsler geometry which presented by Matsumoto-Shimada about the existence of P-reducible metric which is not C-reducible. For this aim, we study a class of Finsler metrics called generalized P-reducible metrics that contains the class of P-reducible metrics. We prove that every generalized P-reducible $(α, β)$-metric with vanishing S-curvature reduces to a Berwald metric or C-reducible metric. It results that there is not any concrete P-reducible $(α,β)$-metric with vanishing S-curvature.

description: We report on the formation of the high-energy empty-state resonance in the electronic spectrum of the iron adatom on the Pt(111) surface. By using the combination of the first-principles methods and the finite-temperature exact diagonalization approach, we show that the resonance is the result of the valence fluctuations between atomic configurations of the impurity. Our theoretical finding is fully confirmed by the results of the scanning tunneling microscopy measurements [M.F. Crommie et al., Phys. Rev. B 48, 2851 (1993)]. In contrast to the previous theoretical results obtained by using local spin density approximation, the paramagnetic state of the impurity in the experiment is naturally reproduced within our approach. This opens a new way for interpretation of STM data collected earlier for metallic surface nanosystems with iron impurities.
Addressing Barriers to Care in HIV-Positive African-American Women through an Interdisciplinary Comprehensive Care Worksheet
Creators: name: Turner, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: HIV care requires patients to be diagnosed, linked to care, retained in care, prescribed
antiretroviral treatment, and reach viral suppression. Progressively more patients fall off the cascade at each step, and in doing so struggle to reach positive outcomes. African-American HIV-positive (black HIV+) women bear a significant burden of HIV morbidity, mortality, incidence, and prevalence. This is due to multiple barriers to care this population faces that prevent them from staying engaged in the cascade. A review of the literature was completed to understand the barrier categories stigma, trauma, social, and medical. These are significant in both prevalence and severity in black HIV+ women. Comprehensive care is healthcare that utilizes providers and communication to ensure every member of the HIV care team understands every barrier a patient faces. This is the best method of care delivery for black HIV+ women because of their many barriers. To facilitate comprehensive care, an Interdisciplinary Comprehensive Care Worksheet (ICCW) was developed to promote provider communication.
The ICCW uses information gathered from the literature review of barriers, and was validated by two HIV care experts. By creating a better method of communication between providers, barriers to care in black HIV+ women can be identified and addressed more easily, increasing the likelihood of positive care outcomes.

description: In this paper, we study generalized Douglas-Weyl $(α, β)$-metrics. Suppose that an regular $(α, β)$-metric $F$ is not of Randers type. We prove that $F$ is a generalized Douglas-Weyl metric with vanishing S-curvature if and only if it is a Berwald metric. Moreover by ignoring the regularity, if $F$ is not a Berwald metric then we find a family of almost regular Finsler metrics which is not Douglas nor Weyl. As its application, we show that generalized Douglas-Weyl square metric or Matsumoto metric with isotropic mean Berwald curvature are Berwald metrics.

description: The fractal dimensions of polymer chains and high-temperature graphs in the Ising model both in three dimension are determined using the conformal bootstrap applied for the continuation of the $O(N)$ models from $N=1$ (Ising model) to $N=0$ (polymer). The unitarity bound below $N=1$ of the scaling dimension for the the $O(N)$-symmetric-tensor develops a kink as a function of the fundamental field as in the case of the energy operator dimension in the Ising model. Although this kink structure becomes less pronounced as $N$ tends to zero, an emerging asymmetric minimum in the current central charge $C_J$ can be used to locate the CFT. It is pointed out that certain level degeneracies at the $O(N)$ CFT should induce these singular shapes of the unitarity bounds. As an application to the quantum and classical spin systems, we also predict critical exponents associated with the $\mathcal{N}=1$ supersymmetry, which could be relevant for locating the correspoinding fixed point in the phase diagram.

The Impact of State Government Partisan Composition on Health Outcomes through Taxation and Healthcare Spending
Creators: name: Kushner, Paul Archimedes
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This paper examines the relationship between the partisan composition of state governments and healthcare in that state. It first shows the theoretical conditions which impact taxation and healthcare spending policies. This theory supports the notion that divided governments produce better healthcare outcomes for individuals than unified state governments. These theoretical conditions are then tested empirically in four iterations. The first iteration considers the direct relationships posited by the theoretical model as stand-alone equations. The second iteration adds variables designed to control for demographic and economic conditions in each state and evaluates the impact of a state’s decision to expand Medicaid. The third iteration of these relationships is a simultaneous estimation of the first iteration. Simultaneous estimation addresses the existence of several variables as both dependent variables in certain equations and independent variables in others. The fourth iteration simultaneously estimates the relationships with the inclusion of state level control variables and an analysis of whether or not a state chose to expand Medicaid. The theoretical results suggest that health outcomes can be altered on a short time horizon by state governments through policy. However, this assertion fails to hold up when properly modeled and the results suggest that state governments do not have a discernable effect on the health outcomes of their citizens on Medicaid. The only finding of the theoretical model that holds up to rigorous econometric examination is that government complexion significantly impacts the tax rate in a state as unified state governments increase taxes in the states they control.

description: We construct a theory in which the gravitational interaction is described only by torsion, but that generalizes the Teleparallel Theory still keeping the invariance of local Lorentz transformations in one particular case. We show that our theory falls, to a certain limit of a real parameter, in the $f(\bar{R})$ Gravity or, to another limit of the same real parameter, in a modified $f(T)$ Gravity, interpolating between these two theories and still can fall on several other theories. We explicitly show the equivalence with $f(\bar{R})$ Gravity for cases of Friedmann-Lemaitre-Robertson-Walker flat metric for diagonal tetrads, and a metric with spherical symmetry for diagonal and non-diagonal tetrads. We do still four applications, one in the reconstruction of the de Sitter universe cosmological model, for obtaining a static spherically symmetric solution type-de Sitter for a perfect fluid, for evolution of the state parameter $ω_{DE}$ and for the thermodynamics to the apparent horizon.

description: A Gravitational Wave Background (GWB) is expected in the universe from the superposition of a large number of unresolved astrophysical sources and phenomena in the early universe. Each component of the background (e.g., from primordial metric perturbations, binary neutron stars, milli-second pulsars etc.) has its own spectral shape. Many ongoing experiments aim to probe GWB at a variety of frequency bands. In the last two decades, using data from ground-based laser interferometric gravitational wave (GW) observatories, upper limits on GWB were placed in the frequency range of ~50-1000 Hz, considering one spectral shape at a time. However, one strong component can significantly enhance the estimated strength of another component. Hence, estimation of the amplitudes of the components with different spectral shapes should be done jointly. Here we propose a method for "component separation" of a statistically isotropic background, that can, for the first time, jointly estimate the amplitudes of many components and place upper limits. The method is rather straightforward and needs negligible amount of computation. It utilises the linear relationship between the measurements and the amplitudes of the actual components, alleviating the need for a sampling based method, e.g., Markov Chain Monte Carlo (MCMC) or matched filtering, which are computationally intensive and cumbersome in a multi-dimensional parameter space. Using this formalism we could also study how many independent components can be separated using a given dataset from a network of current and upcoming ground based interferometric detectors.

description: Many institutions are now approaching two or more decades as archives whose mission is to maintain the usability, authenticity, discoverability, and accessibility of digital artifacts over the very long term. Their very success in becoming the repositories of very large quantities of digital assets has necessitated a maturing focus on the challenges of developing scalable and sustainable processes, procedures, and technologies for managing that content. This entails the care and curation of both primary content and metadata, including and beyond the processes of acquisition, and, possibly, deacquisition. Over the years, the digital preservation community has focused a great deal of attention on workflows, tools, policies, and procedures for content acquisition and ingest. What of the activities of these archives once content is acquired? As curators of content, what questions have we found we need to ask of the content in our archives? What insight do we gain from asking those question about our ingest processes themselves? What are the “curation” workflows we need to apply to the content that has been through our ingest and acquisition workflows? How do we “scale up” the curation and management of living archives, both organizationally and technically, without increasing the costs of managing everlarger and more complex corpora of content, in support of new and increasing modes of access? This workshop will present the experience of its participants in developing those processes, procedures, and technologies for review and discussion.

description: We have discovered a new, rare triple-mode RR Lyr star, EPIC 201585823, in the Kepler K2 mission Campaign 1 data. This star pulsates primarily in the fundamental and first-overtone radial modes, and, in addition, a third nonradial mode. The ratio of the period of the nonradial mode to that of the first-overtone radial mode, 0.616285, is remarkably similar to that seen in 11 other triple-mode RR Lyr stars, and in 260 RRc stars observed in the Galactic Bulge. This systematic character promises new constraints on RR Lyr star models. We detected subharmonics of the nonradial mode frequency, which are a signature of period doubling of this oscillation; we note that this phenomenon is ubiquitous in RRc and RRd stars observed from space, and from ground with sufficient precision. The nonradial mode and subharmonic frequencies are not constant in frequency or in amplitude. The amplitude spectrum of EPIC 201585823 is dominated by many combination frequencies among the three interacting pulsation mode frequencies. Inspection of the phase relationships of the combination frequencies in a phasor plot explains the `upward' shape of the light curve. We also found that raw data with custom masks encompassing all pixels with significant signal for the star, but without correction for pointing changes, is best for frequency analysis of this star, and, by implication, other RR Lyr stars observed by the K2 mission. We compare several pipeline reductions of the K2 mission data for this star.

description: With the negative environmental and social impacts of relying on nonrenewable energy resources becoming more understood by society as a whole, a move to renewable-based energy resources is now and will be increasingly appealing and necessary in coming years. Solar photovoltaics that convert the sun’s light into energy could lead the way to a more sustainable future. In recent years, solar technology as a whole has experienced impressive strides towards less expensive and more efficient cells. Additionally, a variety of new forms of solar technology has entered the stage, such as CIGS, CdTe, quantum dot, perovskite, and organic solar cells. The goal of this study is to identify the most practically and economically feasible emerging solar technology available in 2020 and 2025 and to develop a conceptual plan for its installation on the University of North Carolina at Chapel Hill’s new football indoor practice facility, based on a site analysis, conversion efficiency, and cost projections.

Staff Nurse Perceptions:  Exploring Management, Burnout and Patient Safety
Creators: name: Reynolds, Jennifer R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Nurse burnout is a problem affecting patient safety in all hospitals. Studies suggest that perception of management and teamwork are inversely related to level of burnout and can potentially be related to perception of patient safety. Therefore this study explored the relationships between perceptions of management, teamwork, burnout and patient safety. A secondary data analysis was completed on an AHRQ survey done in early 2015 that explored nurse perceptions of management, teamwork, burnout and patient safety. Responses from 595 nurses on 27 units were analyzed through One-Way ANOVAs and Tukey-Kramer Least Square Means comparisons to explore these perceptions. Relationships between perceived management support, burnout and patient safety as well as perceived teamwork, burnout and patient safety were observed at the hospital level. There were interactions found based on intensity of care (intensive care units: lower management, teamwork and patient safety; higher burnout) and patient populations (Children’s Hospital: lower management, teamwork and patient safety; higher burnout) compared to those within each groups. Results were as expected and comparable to other studies for perceptions based on hospital and intensity of care groupings. Patient population findings were not as expected with the Children’s Hospital having greater burnout and lower perceptions of management, teamwork and patient safety compared to adult populations. This study supports nurse leaders receiving training regarding better supporting staff and instilling teamwork to combat burnout and improve patient safety. Further research should be done on the relationship between management and teamwork.

description: Efficient search of the environment requires that people attend to the desired elements in a scene and ignore the undesired ones. Recent research has shown that this endeavor can benefit from the ability to proactively suppress distractors with known features, but little is known about the mechanisms that produce the suppression. We show here in five experiments (n=120 college students) that, surprisingly, identification of a sought-for target is enhanced when it is grouped with a suppressed distractor compared to when it is in a different perceptual group. The results show that the suppressive mechanism not only downweights undesired elements, but it also enhances responses to task-relevant elements in competition for attention with the distractor, fine-tuning the suppression. The findings extend the understanding of how people efficiently process their visual world.

description: Finding more efficient ways of exploring the doping phase diagrams of high temperature superconductors as well as probing the fundamental properties of these materials are essential ingredients for driving the discovery of new materials. We use a doping technique involving gating with ionic liquids to systematically and continuously tune the T$_{c}$ of superconducting La$_{2}$CuO$_{4+x}$ thin films. We probe both the transport properties and the penetration depth of these samples and find that Homes scaling $λ^{-2}\proptoσT_{c}$ is obeyed, consistent with these materials being in the dirty limit. This result is independent of the precise mechanism for the gating process as all of the parameters of the scaling relationship are determined by direct measurements on the films.

description: Abstract: In 2015, the adoption of resolution A/RES/70/1 2030, Transforming our world: the 2030 Agenda for Sustainable Development (UN Agenda 2030) was an important statement of future intent for UN member states. The Agenda touches the entire geography of the globe covering potentially all aspects of how society, economy, the environment and the polity are organized. The working philosophy of our approach is based on the existing open governance adopted by the UN HLPF at a global level. We wish to explore a form of interoperability of public policy dialogues at national and global levels. By exploring HLPF structures in national parliaments and making them interoperable with the UN HLPF we are proposing how a body like the UN HLPF can induce ‘whole-of-society’ participation at different levels, but particularly at the binding level of the nation-state. This has the potential to create very effective global ‘whole-of-society’ partnerships, led by governments that set, implement and review sustainable development public policies around the globe. We will use Ireland as a case study to show how our proposals might be integrated to the existing policymaking processes without being overtly disruptive.

description: Using the idea of regularisation of singularities due to the variability of the fundamental constants in cosmology we study the cyclic universe models. We find two models of oscillating and non-singular mass density and pressure ("non-singular" bounce) regularised by varying gravitational constant $G$ despite the scale factor evolution is oscillating and having sharp turning points ("singular" bounce). Both violating (big-bang) and non-violating (phantom) null energy condition models appear. Then, we extend this idea onto the multiverse containing cyclic individual universes with either growing or decreasing entropy though leaving the net entropy constant. In order to get an insight into the key idea, we consider the doubleverse with the same geometrical evolution of the two "parallel" universes with their physical evolution (physical coupling constants $c(t)$ and $G(t)$) being different. An interesting point is that there is a possibility to exchange the universes at the point of maximum expansion -- the fact which was already noticed in quantum cosmology. Similar scenario is also possible within the framework of Brans-Dicke theory where varying $G(t)$ is replaced by the dynamical Brans-Dicke field $ϕ(t)$ though these theories are slightly different.

A Woman's Level: The Insight of Campaign Consultants on Female Candidates
Creators: name: Schneider, Margaret
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: In 2014, female candidates are still a minority in electoral politics. The general
election in 2014 featured 169 female candidates for U.S. Congress. This
study examines four campaigns of female candidates for U.S. Congress. Interviews with
campaign staff shed light on how female candidates choose issues and plan
communication strategy. Contrary to prior academic literature, findings from interviews suggest that party affiliation is a better determinant of strategy than gender. Staffers acknowledge gender and stereotypes associated with gender; however, in 2014 these staffers did not think gender was an important factor in the general election.

description: Thick fully depleted CCDs, while enabling wide spectral response, also present challenges in understanding the systematic errors due to 3D charge transport. This 2014 Workshop on Precision Astronomy with Fully Depleted CCDs covered progress that has been made in the testing and modeling of these devices made since a workshop by the same name in 2013. Presentations covered the science drivers, CCD characterization, laboratory measurements of systematics, calibration, and different approaches to modeling the response and charge transport. The key issue is the impact of these CCD sensor features on dark energy science, including astrometry and photometry. Successful modeling of the spatial systematics can enable first order correction in the data processing pipeline.

description: In order for sources of coherent high brightness and intensity THz and X-Ray radiation to be accepted by university or industrial R&D laboratories, truly compact, high current and efficient particle accelerators are required. The demand for compactness and efficiency can be satisfied by superconducting RF energy recovery linear accelerators (SRF ERL) allowing effectively minimising the footprint and maximising the efficiency of the system. However such set-ups are affected by regenerative beam-break up (BBU) instabilities which limit the beam current and may terminate the beam transport as well as energy recuperation. In this paper we suggest and discuss a SRF ERL with asymmetric configuration of resonantly coupled accelerating and decelerating cavities. In this type of SRF ERL an electron bunch is passing through accelerating and decelerating cavities once and, as we show in this case, the regenerative BBU instability can be minimised allowing high currents to be achieved. We study the BBU start current in such an asymmetric ERL via analytical and numerical models and discuss the properties of such a system.

A Jacobian generalization of the pseudo Nambu-Goldstone bosons potential

description: We enlarge the classes of inflaton and quintessence fields by generalizing the pseudo Nambu--Goldstone boson potential by means of elliptic Jacobian functions, which are characterized by a parameter $k$. We use such a generalization to implement an inflationary era and a late acceleration of the universe. As an inflationary model the Jacobian generalization leads us to a number of e-foldings and a primordial spectrum of perturbations compatible with the {\it Planck collaboration} 2015. As a quintessence model, a study of the evolution of its equation of state (EoS) and its $w'$--$w$ plane helps us to classify it as a thawing model. This allows us to consider analytical approximations for the EoS recently discovered for thawing quintessence. By using JLA Supernovae Ia and Hubble parameter $H(z)$ data sets, we perform an observational analysis of the viability of the model as quintessence.

description: Forty-two lactic acid bacteria were isolated from 28 pickles and yoghurt samples, and screened for their antimicrobial efficacy against certain multidrug resistant (MDR) bacteria using well diffusion method. A strain Pediococcus pentosaceus N33 (MF062087) showed the best inhibitory effects against both Brevibacillus brevis H18 (MG637284) and Lysinibacillus fusiformis R29 (MG637285). Pediococcus pentosaceus N33 strain produced high thermostable antimicrobial compound as indicated by heat treatment between 60 and 100°C for 20 min as well as at 121°C for 15 min. It is a proteinaceous compound highly active at acidic pH (2–6). The antimicrobial compound was extracted and precipitated by 70% ammonium sulfate and finally fractionated using Sephadex G50 column. The molecular weight of pure compound was 10 kDa using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis. The spectroscopic analysis based on UV, IR, NMR and MS analyses were used to characterize and identify the pure antimicrobial compound. From the characterization and identification of this inhibitory compound, it was observed that the target compound contains carotenoid pigment in addition to protein. This carotenoid pigment was identified as pedioxanthin which is the first observed from this strain. Our results evaluated the potential activity of Pediococcus pentosaceus N33 strain as a probiotic agent and its potential contribution for food industry and pharmaceutical applications.
