description: In an SU(N) gauge field theory, the n-point Green functions, namely, propagators and vertices, transform under the simultaneous local gauge variations of the gluon vector potential and the quark matter field in such a manner that the physical observables remain invariant. In this article, we derive this intrinsically non perturbative transformation law for the quark propagator within the system of covariant gauges. We carry out its explicit perturbative expansion till O(g_s^6) and, for some terms, till O(g_s^8). We study the implications of this transformation for the quark-anti-quark condensate, multiplicative renormalizability of the massless quark propagator, as well as its relation with the quark-gluon vertex at the one-loop order. Setting the color factors C_F=1 and C_A=0, Landau-Khalatnikov-Fradkin transformation for the abelian case of quantum electrodynamics is trivially recovered.

Interindividual Differences in Cell Type Proportions During Human Cortical Neurogenesis
Creators: name: Mory, Jessica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Cortical neurogenesis occurs during prenatal brain development and leads to the production of all of the excitatory neurons of the cortex. Neurogenesis may be affected by common genetic variation in the human population, leading to genetically mediated alterations in brain structure and function. Using an in vitro model of cortical development with samples obtained during neurogenesis, we analyzed interindividual differences between 40 donors for immunolabeled proportions of progenitors, proliferating progenitors, and neurons. We found a smaller degree of variation within technical replicates of a donor as opposed to between random donors, indicating that this phenotype can be reproducibly measured. After controlling for some technical and biological variables, we found that percentages of progenitors and proliferating progenitors, as well as the total number of nuclei, showed a significant positive association with gestation week. We also saw a significant positive correlation between multiple combinations of cell types, which was consistent with our expectations regarding the fluctuation of progenitor and neuron numbers during neurogenesis. Our results demonstrate that the in vitro culture system represents a reproducible, biologically valid system for performing genetic association studies to further investigate the relationship between common genetic variation and cellular phenotypes during neurogenesis.

description: The Domain Name System (DNS) is one of the most important components of the Internet infrastructure. DNS relies on a delegation-based architecture, where resolution of names to their IP addresses requires resolving the names of the servers responsible for those names. The recursive structures of the inter dependencies that exist between name servers associated with each zone are called dependency graphs. System administrators' operational decisions have far reaching effects on the DNSs qualities. They need to be soundly made to create a balance between the availability, security and resilience of the system. We utilize dependency graphs to identify, detect and catalogue operational bad smells. Our method deals with smells on a high-level of abstraction using a consistent taxonomy and reusable vocabulary, defined by a DNS Operational Model. The method will be used to build a diagnostic advisory tool that will detect configuration changes that might decrease the robustness or security posture of domain names before they become into production.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In this project, a substitute for 5-CSRTT has been developed. The new task includes traits from 5-CSRTT and CPT, which is called 2-CSRTT. To improve data accuracy and reduce human efforts in animal training, a new 2-CSRTT box is developed. The results suggest that the 2-CSRTT box reduces the reaction time in trials, implying that the efficacy of the test has been improved. Also, the automated part of the box has shown to reduce human efforts. This project will help researchers in the Frohlich Lab to train ferrets in a shorter period of time, and the behavioral results will be more useful in data analysis.

description: The frequency dependent specific heat has been measured under pressure for the molecular glass forming liquid 5-polyphenyl-4-ether in the viscous regime close to the glass transition. The temperature and pressure dependence of the characteristic timescale associated with the specific heat is compared to the equivalent timescale from dielectric spectroscopy performed under identical conditions. It is shown that the ratio between the two timescales is independent of both temperature and pressure. This observation is non-trivial and demonstrates the existence of specially simple molecular liquids in which different physical relaxation processes are both as function of temperature and pressure/density governed by the same underlying "inner clock". Furthermore, the results are discussed in terms of the recent conjecture that van der Waals liquids, like the measured liquid, comply to the isomorph theory.

Analysis of the Spanish Language in Violent Situations from Specific Spanish Films
Creators: name: Deol, Siarra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In this thesis, I analyzed the Spanish language of six movies: El Infierno, Amores Perros, Sobreviviendo Guazapa, Voces Inocentes, La Vendedora de Rosas, and No Future to explain how the language is used in violent environments. Thus, each film contained element(s) of violence whether it related to physical, sexual, drug violence, or war. Since I focused on a linguistic analysis, I divided my research into three linguistic levels: lexical, phonetics, and morphology. The results of the analysis showed that the environment of violence as a sociolinguistic factor supports an overuse of slang (lexical level) in the movies related to drugs and sexual violence between young people. Aside from this, there is a change of registers (formal and informal) with the use of certain pronouns vos, tú, and usted (morphological level) not only to express distance and closeness, but also domination by using violent language with the pronouns. The phonetic level demonstrated the characteristics of the dialect of Medellín in La Vendedora de Rosas and No Futuro. Therefore, these Colombian films (focused on the lower class of society) saw a very narrow portrayal of the language. There were similar linguistic characteristics in the films, El Infierno and Amores Perros, but the inclusion of code-switching, the words utilized from a cartel leader, and the pronunciation is intended to represent the Spanish of Mexico near the border. One of the films from El Salvador, Voces Inocentes (based on a real story), displayed standard Spanish compared to the film, Sobreviviendo Guazapa. The standard Spanish is present due to the circumstances surrounding the film and its historical purposes. The language is altered depending on one’s environment, but the films do not represent an entire group of people or does not speak for all.

Towards discrimination between galactic and intergalactic axion-photon mixing

description: There exists a growing evidence for the anomalous transparency of the Universe for energetic gamma rays. Popular explanations include conversion of photons into hypothetical axion-like particles (ALPs) and back in astrophysical magnetic fields. Two distinctive scenarios of this conversion have been put forward: either it happens in the (host galaxy of the) gamma-ray source and in the Milky Way, or the photon-ALP oscillations take place in the intergalactic magnetic fields all along the way between the source and the observer. Here we point out that, given recent astrophysical constraints on ALPs and on intergalactic magnetic fields, these two mechanisms imply very different ALP masses and couplings. Therefore, confirmation of the anomalies and identification of one of the scenarios would mean cornering of ALP parameters to a particular narrow region. We discuss approaches to distinguish between the two mechanisms and present some preliminary indications in favour of the galactic scenario.

Does gaining health insurance improve access to appropriate sources of primary care? Evidence from Medicaid Expansion in New York State
Creators: name: Caprise, Isabel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Medicaid patients have difficulty accessing primary care providers, especially when compared to privately-insured patients, leading to inefficient utilization of emergency departments for primary care. This study aims to examine whether gaining health insurance improves access to appropriate sources of primary care. In particular, this study examines whether gaining Medicaid coverage through the Affordable Care Act’s Medicaid Expansion program improves access to primary care by utilizing a difference-in-difference design to compare the changes in emergency department utilization between the treatment group (those who gain coverage from this policy) and the control group before and after the policy implementation. Visit-level emergency department data for the state of New York (2012-2014) is used to observe changes in emergency department utilization, specifically the number of primary care-natured visits, as a result of the policy implementation. This study finds that Medicaid Expansion lead to an increase in primary care-natured visits in emergency departments by newly-covered Medicaid patients as well as an increase in the probability that a visit was primary care-natured. These results suggest that despite improved insurance status, there are still barriers to access to primary care providers for Medicaid patients.

description: Humans can steadily and gently grasp unfamiliar objects based on tactile perception. Robots still face challenges in achieving similar performance due to the difficulty of learning accurate grasp-force predictions and force control strategies that can be generalized from limited data. In this article, we propose an approach for learning grasping from ideal force control demonstrations, to achieve similar performance of human hands with limited data size. Our approach utilizes objects with known contact characteristics to automatically generate reference force curves without human demonstrations. In addition, we design the dual convolutional neural networks (Dual-CNN) architecture which incorporats a physics-based mechanics module for learning target grasping force predictions from demonstrations. The described method can be effectively applied in vision-based tactile sensors and enables gentle and stable grasping of objects from the ground. The described prediction model and grasping strategy were validated in offline evaluations and online experiments, and the accuracy and generalizability were demonstrated.

description: As users become confronted with a deluge of provenance data, dedicated techniques are required to make sense of this kind of information. We present Aggregation by Provenance Types, a provenance graph analysis that is capable of generating provenance graph summaries. It proceeds by converting provenance paths up to some length k to attributes, referred to as provenance types, and by grouping nodes that have the same provenance types. The summary also includes numeric values representing the frequency of nodes and edges in the original graph. A quantitative evaluation and a complexity analysis show that this technique is tractable; with small values of k, it can produce useful summaries and can help detect outliers. We illustrate how the generated summaries can further be used for conformance checking and visualization.

description: I present a technical report indicating that the two methods used for calculating characteristic functions for the work distribution in weakly driven quantum master equations are equivalent. One involves applying the notion of quantum jump trajectory [Phys. Rev. E 89, 042122 (2014)], while the other is based on two energy measurements on the combined system and reservoir [Silaev, et al., Phys. Rev. E 90, 022103 (2014)]. These represent backward and forward methods, respectively, which adopt a very similar approach to that of the Kolmogorov backward and forward equations used in classical stochastic theory. The microscopic basis for the former method is also clarified. In addition, a previously unnoticed equality related to the heat is also revealed.

description: It is essential that all algorithms are exhaustively, somewhat, and intelligently evaluated. Nonetheless, evaluating the effectiveness of optimization algorithms equitably and fairly is not an easy process for various reasons. Choosing and initializing essential parameters, such as the size issues of the search area for each method and the number of iterations required to reduce the issues, might be particularly challenging. As a result, this chapter aims to contrast the Whale Optimization Algorithm (WOA) with the most recent algorithms on a selected set of benchmark problems with varying benchmark function hardness scores and initial control parameters comparable problem dimensions and search space. When solving a wide range of numerical optimization problems with varying difficulty scores, dimensions, and search areas, the experimental findings suggest that WOA may be statistically superior or inferior to the preceding algorithms referencing convergence speed, running time, and memory utilization.

description: The nearly continuous light curves with micromagnitude precision provided by the space mission Kepler are revolutionising our view of pulsating stars. They have revealed a vast sea of low-amplitude pulsation modes that were undetectable from Earth. The long time base of Kepler light curves allows an accurate determination of frequencies and amplitudes of pulsation modes needed for in-depth asteroseismic modeling. However, for an asteroseismic study to be successful, the first estimates of stellar parameters need to be known and they can not be derived from the Kepler photometry itself. The Kepler Input Catalog (KIC) provides values for the effective temperature, the surface gravity and the metallicity, but not always with a sufficient accuracy. Moreover, information on the chemical composition and rotation rate is lacking. We are collecting low-resolution spectra for objects in the Kepler field of view with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, Xinglong observatory, China). All of the requested fields have now been observed at least once. In this paper we describe those observations and provide a database of use to the whole astronomical community.

description: We report on the algorithms and numerical methods used in Viriato, a novel fluid-kinetic code that solves two distinct sets of equations: (i) the Kinetic Reduced Electron Heating Model (KREHM) equations [Zocco & Schekochihin, Phys. Plasmas 18, 102309 (2011)] (which reduce to the standard Reduced-MHD equations in the appropriate limit) and (ii) the kinetic reduced MHD (KRMHD) equations [Schekochihin et al., Astrophys. J. Suppl. 182:310 (2009)]. Two main applications of these equations are magnetised (Alfvenic) plasma turbulence and magnetic reconnection. Viriato uses operator splitting (Strang or Godunov) to separate the dynamics parallel and perpendicular to the ambient magnetic field (assumed strong). Along the magnetic field, Viriato allows for either a second-order accurate MacCormack method or, for higher accuracy, a spectral-like scheme composed of the combination of a total variation diminishing (TVD) third order Runge-Kutta method for the time derivative with a 7th order upwind scheme for the fluxes. Perpendicular to the field Viriato is pseudo-spectral, and the time integration is performed by means of an iterative predictor-corrector scheme. In addition, a distinctive feature of Viriato is its spectral representation of the parallel velocity-space dependence, achieved by means of a Hermite representation of the perturbed distribution function. A series of linear and nonlinear benchmarks and tests are presented, including a detailed analysis of 2D and 3D Orszag-Tang-type decaying turbulence, both in fluid and kinetic regimes.

Single neutral substitutional 3d-transition metal in GeTe and GeSb2Te4 by the screened exchange functional

Year: 2015
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Fe doped GST has shown experimentally the ability to alter its magnetic properties by phase change. In this work, we use screened exchange hybrid functional to study the single neutral substitutional 3d transition metal (TM) in crystalline GeTe and GeSb2Te4. By curing the problem of local density functional (LDA) such as over delocalization of the 3d states, we find that Fe on Ge/Sb site has its majority d states fully occupied while its minority d states are empty, which is different than previous predicted electronic configuration by LDA. From early transition metal Cr to heavier Ni, the majority 3d states are gradually populated until fully occupied and then the minority 3d states begin to be filled. In order to study the magnetic contrast, we use lower symmetry crystalline GeTe and GeSb2Te4 as the amorphous phases, respectively, which has been proposed to model the medium range disordering. We find that only Co substitution in r-GeSb2Te4 and s-GeSb2Te4 shows magnetic contrast. The experimental magnetic contrast for Fe doped GST may be due to additional TM-TM interaction, which is not included in our model. It can also be possible that these lower symmetry crystalline models are not sufficient to characterize the magnetic properties of real 3d TM doped amorphous GST.
A Scoping Review of Adolescent Prenatal Care Research

description: Even though the overall rate of adolescent and teen pregnancy has dropped 64% in the United States in the last 20 years, the United States still has one of the highest rates of teen pregnancies among western-developed countries. Utilization of prenatal care (PNC) can lead to better perinatal outcomes for both mother and baby, however pregnant adolescents receive the least amount of prenatal care compared to other pregnant women. The aim of this scoping review was to examine the focus and extent of published adolescent prenatal care research in the United States between 2010 and 2020, with nurses in the PNC model. After extensive database searches, seven (n=7) studies met the inclusion criteria. Findings were categorized into 8 themes: types of PNC, PNC utilization, barriers and stigma related to PNC, types of disciplines involved with PNC, PNC setting and geographic location, sociodemographic characteristics of the pregnant adolescent, and maternal and infant variables and outcomes. Most of the research focused on the type of PNC received and maternal and infant outcomes; findings suggested that a group PNC model was an optimal choice for pregnant adolescents. PNC utilization was primarily associated with healthy perinatal outcomes for mother and baby. Further research on adolescent PNC is needed because we found a paucity of current studies, research designs were primarily descriptive, and measurement of PNC utilization varied. Additional research is needed to inform nursing practice associated with providing prenatal care to the vulnerable population of pregnant adolescents and their babies.

description: Recent years have seen an increasing number of deployment of fleets of autonomous vehicles. As the problem scales up, in terms of autonomous vehicles number and complexity of their objectives, there is a growing need for decision-support tooling to help the operators in controlling the fleet. In this paper, we present an automated planning system developed to assist the operators in the CoHoMa II challenge, where a fleet of robots, remotely controlled by a handful of operators, must explore and progress through a potential hostile area. In this context, we use planning to provide the operators with suggestions about the actions to consider and their allocation to the robots. This paper especially focus on the modelling of the problem as a hierarchical planning problem for which we use a state-of-the-art automated solver.

description: A search for light long-lived particles decaying to displaced jets is presented, using a data sample of proton-proton collisions at a center-of-mass energy of 13.6 TeV, corresponding to an integrated luminosity of 34.7 fb$^{-1}$, collected with the CMS detector at the CERN LHC in 2022. Novel trigger, reconstruction, and machine-learning techniques were developed for and employed in this search. After all selections, the observations are consistent with the background predictions. Limits are presented on the branching fraction of the Higgs boson to long-lived particles that subsequently decay to quark pairs or tau lepton pairs. An improvement by up to a factor of 10 is achieved over previous limits for models with long-lived particle masses smaller than 60 GeV and proper decay lengths smaller than 1 m. The first constraints are placed on the fraternal twin Higgs and folded supersymmetry models, where the lower bounds on the top quark partner mass reach up to 350 GeV for the fraternal twin Higgs model and 250 GeV for the folded supersymmetry model.

Contact interactions between particle worldlines

description: We construct contact interactions for bosonic and fermionic point particles. We first relate the resulting theories to classical electrostatics by taking functional averages over worldlines whose endpoints are fixed to charged particles. Counting those paths which pass through a space-time point $x^μ$ gives the static electric field at that point, provided we take the limit where the length measured along the worldlines is large. We also investigate corrections to the classical field that arise beyond leading order in this limit before constructing a theory of point particles that interact when their worldlines intersect. We quantise this theory and show that the partition function contains propagator couplings between the endpoints of the particles before discussing how this is related to the worldline formalism of quantum field theory and general action at a distance theories.

The Qualities of Healthcare Providers that Influence Patient Satisfaction
Creators: name: Coogan, Erin

description: Patient satisfaction is becoming a significant measurement of patient outcomes. Previous research has established a correlation between high patient satisfaction and improved patient outcomes (Carr & Nicolau, 2017). This report analyzes the results of previous patient satisfaction studies, as well as a novel pilot study that surveys individuals on the qualities of healthcare professionals that most influences their satisfaction. The factors that researchers found to be most influential on patient satisfaction include communication, interpersonal skills, patient involvement, quality of medical care, and expectations (Anderson, Barbara, & Feldman, 2007). These qualities, as well as demographic data, were included in the fifteen-question survey. Of the 141 responses that were analyzed, the majority of individuals chose the quality of medical care as the most important factor, followed by communication skills and interpersonal skills. This research can be utilized by healthcare professionals to develop training programs to improve their patient satisfaction ratings. This can translate into better reviews and increased reimbursement from insurance companies.
Simulating open quantum dynamics with time-dependent variational matrix product states: Towards microscopic correlation of environment dynamics and reduced system evolution

description: Many-body approaches to open quantum systems have recently become powerful tools for investigating the detailed role of dissipative environments in diverse non-equilibrium molecular and condensed matter processes. Here, we report the development of an efficient algorithm that utilises a time-dependent variational principle for matrix product states to evolve large system-environment states. By thus capturing all system-environment correlations, we reproduce the highly non-perturbative, quantum-critical dynamics of the zero temperature spin-boson model, and then exploit the many-body information to output a complete time-frequency spectrum of the environmental excitations. We highlight how theoretical 'environmental spectra' could yield valuable insights into a wide range of complex dissipative processes, by showing that correlated motion of modes entangled with the spin can appear with persistent vibrational coherence, in spite of incoherent spin relaxation.

description: We have developed experimental methods for the generation of chirped laser pulses of controlled frequency evolution in the nanosecond pulse length range for coherent atomic interaction studies. The pulses are sliced from the radiation of a cw external cavity diode laser while its drive current, and consequently its frequency, are sinusoidally modulated. By the proper choice of the modulation parameters, as well as of the timing of pulse slicing, we can produce a wide variety of frequency sweep ranges during the pulse. In order to obtain the required frequency chirp, we need to stabilize the center frequency of the modulated laser and to measure the resulting frequency evolution with appropriate temporal resolution. These tasks have been solved by creating a beat signal with a reference laser locked to an atomic transition frequency. The beat signal is then analyzed, as well as its spectral sideband peaks are fed back to the electronics of the frequency stabilization of the modulated laser. This method is simple and it has the possibility for high speed frequency sweep with narrow bandwidth that is appropriate, for example, for selective manipulation of atomic states in a magneto-optical trap.
Echoes of a Mill Mother’s Lament: Legacies of Labor Activism in Gastonia, North Carolina

description: In 1929, workers at the Loray Mill in Gastonia, North Carolina, organized by the communist-led National Textile Workers Union, went on strike for higher wages, better working conditions and union recognition. This strike would end tragically with the deaths of labor organizer Ella May Wiggins and Gastonia Police Chief Orville Aderholt. Almost sixty years later however, in 1987, at the same location as the original Loray Mill workers at the Firestone Textiles mill would initiate their own union organizing effort. Both supporters and opponents of the union organizing effort at the Firestone Mill in Gastonia would draw on the legacy of the strike, advocating different interpretations of the events of 1929 to support their respective sides and drawing on this local labor history to make their case. The story of the 1987-1988 Gastonia Firestone unionization effort provides a counter-example to the prevailing trends in the American labor movement during the 1980's as well as insight into how local labor history can shape later organizing efforts.
