description: Due to instanton effects, gauge-theoretic large N expansions yield asymptotic series, in powers of 1/N^2. The present work shows how to generically make such expansions meaningful via their completion into resurgent transseries, encoding both perturbative and nonperturbative data. Large N resurgent transseries compute gauge-theoretic finite N results nonperturbatively (no matter how small N is). Explicit calculations are carried out within the gauge theory prototypical example of the quartic matrix model. Due to integrability in the matrix model, it is possible to analytically compute (fixed integer) finite N results. At the same time, the large N resurgent transseries for the free energy of this model was recently constructed. Together, it is shown how the resummation of the large N resurgent transseries matches the analytical finite N results up to remarkable numerical accuracy. Due to lack of Borel summability, Stokes phenomena has to be carefully taken into account, implying that instantons play a dominant role in describing the finite N physics. The final resurgence results can be analytically continued, defining gauge theory for any complex value of N.

The Japanese Experience of Giving Birth in North Carolina
Creators: name: Cooper, Alyssa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Childbirth is a physiological and deeply social process, which only a fraction of the population is capable of undertaking. This rite of passage simultaneously shapes and is shaped by core societal values and thereby is inherently political. The anthropology of birth has a well-established, empirically based literature produced from more than 40 years of ethnographic research, and numerous scholars identify in the study of reproduction central theories for anthropology. This is because the study of childbirth demonstrates how reproduction reflects and shapes core societal values and structures, and cross-cultural perspectives reveal biomedical obstetrics as a culturally shaped phenomena (Davis-Floyd, 1992; Fiedler, 1996; Ivry, 2009; Rapp, 2001; Sargent & Gulbas, 2011). 
The Triangle Area (Raleigh/Durham/Cary) has a Japanese community that consists of both expatriates and immigrants who are drawn to the area for a variety of reasons. This creates a local Japanese community in which women arrive with their husbands (and children), anticipating giving birth in American hospitals. These women are isolated from their families and communities back home, and they have many worries surrounding this experience due to language and cultural barriers. My hope is for this research to offer future mothers and families insight into the experience and suggest ways the Triangle Japanese community can provide support. 
As a Japanese-American, I am focused on this specific community where I hold a unique advantage of both bilingualism and biculturalism, allowing me to see how the experiences of these Japanese women reflect larger societal and cultural patterns of birthing in American biomedicine. Using ethnographic methods, I conducted 90 minute in-depth interviews with eight Japanese women who have given birth in American hospitals. In Chapter 1, I discuss how the cultural values of the Japanese women shaped their birth experiences when encountering American values in hospitals. In Chapter 2 I discuss how the Japanese women related to the differing Japanese and American cultural attitudes towards autonomy, paternalism, and choice in Triangle health care contexts, an analysis that offers a cultural perspective on the notion of patient-centered care. In Chapter 3 I discuss where Japanese women sought social support and knowledge during their pregnancy and birth in the US. This research gives insights into specific procedures and approaches of local hospitals that are lacking or working especially well in addressing cultural and language barriers of birthing persons and partners.

Effect of a Short-term High-fat Diet on Lipid Metabolites of Initiation and Resolution of Lung Inflammation
Creators: name: Zijian Li
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Background: 
The onset and resolution of inflammation are regulated by lipid metabolites enzymatically derived from n-3 and n-6 polyunsaturated fatty acids (PUFAs) such as arachidonic acid (AA, C20:4n-6), eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid (DHA; C22:6n-3). These PUFAs are released upon initial phases of an immune response and through a process called lipid mediator class switching, initiates the biosynthesis of specialized pro-resolving mediators (SPMs). SPMs, known as protectins, resolvins, maresins and lipoxins, have an active role in inflammation resolution. Unresolved or chronic inflammation is associated with pulmonary diseases. We have previously shown that long-term high-fat dietary intervention induces obesity-driven SPM dysregulation, yet the short-term impact of an obesogenic diet on SPM regulation is unknown, particularly on the lungs. Profiling the lung lipidome following short-term high fat diet could further shed light on the obesity-inflammation-lung diseases link during the earlier phase of disease onset. 

Methods:
Six-week-old male C57BL/6J mice were purchased from Jackson Laboratory. The mice were randomly assigned to high fat (HF, 60% calories from fat) and low-fat (LF, 10% calorie from fat) diet group (n=6 for each group) for 5 weeks. Body weight and dietary intake were recorded weekly. At the end of the fifth week, the mice were sacrificed by isoflurane drop anesthesia followed by dissection to harvest both the left and right lungs. The lung samples were analyzed by mass spectrometry (LC-MS/MS) to quantify SPMs, their metabolic intermediates, and other PUFA-derived mediators. T-tests controlling for false discovery rate was used to compare the amount of lipid mediators present in the lung tissues of each diet group.

Results:
A 5-week high fat diet (HFD) induced obesity in male C57BL/6J mice. However, the intervention did not produce significantly different changes in lung lipidomic profile. We demonstrated that neither individual metabolite nor the total levels of metabolites derived from PUFAs in lungs were altered by short-term HFD. 

Conclusion:
Changes in PUFA derived inflammation markers and other lipid mediators in the lungs of C57BL/6J mice do not occur after a course of a 5-week HFD relative to a lean control diet.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Educational forum posts processing is a demanding and time-consuming task for instructors. In this thesis, we present the kernels of a system based on natural language processing. Together with future implementation of the database, receiving and sending module, and user interface, the system can be served as an intelligent teaching assistant for educational forum posts processing for small courses, which aims at alleviating the workload of instructors. Currently, this system is capable of conducting the following tasks: (a) Automatically label new posts into pre-designed categories. (b) Identify posts whose content is similar or identical to another existing post. (c) Identify posts that do not contain enough information for the instructors to understand or answer the question. (d) Automatically answer students' questions about the implementation of coding assignments using English translation of the solution code. We applied six language models, four prediction models, together with two API packages to build the system. Our result showed that the system reached the highest accuracy of over 90\% on task (a), over 98\% on task (b), and over 95\% on task (c), which shows the bright prospect of extending it to a fully functional and practical plug-in.

Topics in supersymmetry and physics beyond the standard model
Creators: name: Fortin, Jean-François
Publisher: name: No Publisher Supplied
Year: 2009

description: In this thesis we explore different aspects related to the central concepts of supersymmetry and physics beyond the Standard Model. We start by investigating fine-tuning in the minimal supersymmetric extension of the Standard Model, where the regions with the minimal amount of fine-tuning of electroweak symmetry breaking are found. Afterwards, we concentrate on a more formal aspect of supersymmetry, studying spontaneous symmetry breaking in supersymmetry using the superspace formalism. Thereafter we direct our attention to supersymmetry as physics beyond the Standard Model, looking more specifically at supersymmetry breaking in metastable states. First, we discuss possible undetected Higgs decays in the Pentagon model with renormalizable lepton number violating couplings which also explain neutrino masses. Second, we generalize metastable supersymmetry breaking in supersymmetric quantum chromodynamics to phenomenologically viable models of direct gauge mediation by adding single and multitrace deformations. Third, we introduce a new model of physics beyond the Standard Model, the Pyramid Scheme, and study its implications, focusing on dark matter and its astrophysical signatures in particular. Four, we examine tunneling constraints in models of Cosmological Supersymmetry Breaking, arguing that these models can have no supersymmetric vacuum states in the infinite Planck mass limit. Finally, we present a general study of the possible gamma ray signatures coming from dark matter annihilation or decay.
Amplitude-phase coupling drives chimera states in globally coupled laser networks

description: For a globally coupled network of semiconductor lasers with delayed optical feedback, we demonstrate the existence of chimera states. The domains of coherence and incoherence that are typical for chimera states are found to exist for the amplitude, phase, and inversion of the coupled lasers. These chimera states defy several of the previously established existence criteria. While chimera states in phase oscillators generally demand nonlocal coupling, large system sizes, and specially prepared initial conditions, we find chimera states that are stable for global coupling in a network of only four coupled lasers for random initial conditions. The existence is linked to a regime of multistability between the synchronous steady state and asynchronous periodic solutions. We show that amplitude-phase coupling, a concept common in different fields, is necessary for the formation of the chimera states.

Population dynamics in Floquet realisation of Harper-Hofstadter Hamiltonian

Year: 2015
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study the recent Floquet-realisation of the Harper-Hofstadter model in a gas of cold bosonic atoms. We study in detail the scattering processes in this system in the weakly interacting regime due to the interplay of particle interactions and the explicit time dependence of the Floquet states that lead to band transitions and heating. We focus on the experimentally used parameters and explicitly model the transverse confining direction. Based on transition rates computed within the Floquet-Fermi golden rule we obtain band population dynamics which are in agreement with the dynamics observed in experiment. Finally, we discuss whether and how photon-assisted collisions that may be the source heating and band population dynamics might be suppressed in the experimental setup by appropriate design of the transverse confining potential. The suppression of such processes will become increasingly important as the experiments progress into simulating strongly interacting systems in the presence of artificial gauge fields.

ORAL PRESENTATION COMPETENCE IN VIRTUAL REALITY
Creators: name: Hou, Chenyu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Oral presentation is increasingly important in higher education and workplaces, while many students reported that their presentation skills were inadequate for work or academic presentations. Traditional instructional methods to improve presentation skills are time- consuming, so many researchers have attempted to use automated feedback systems to provide students with timely feedback and virtual simulations to offer a practice environment. Presentation competence is a multidimensional construct with cognitive, behavioral and emotional components. However, studies on the affective components during oral presentation have concentrated on pathological public speaking anxiety, while limited studies have addressed the variety of emotions in virtual simulations that predict the virtual reality efficacy. The current study focused on students’ emotional experiences of practicing oral presentation in a virtual simulation. The quantitative analysis shows that participants did not improve their presentation skills with the virtual simulations. The study utilized code mapping analysis to analyze qualitative data from focus groups and survey answers. Four kinds of emotions emerged: 1) Increased level of comfort; 2) Frustration with the feedback; 3) Awkwardness with unrealistic simulations; 4) Anxiety over negative avatar interactions. Limitations and future research directions are also identified.

Investigating perceptions of socioeconomic status on levels of comfort in expressing racism
Creators: name: Salmeron, Miya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Today, it has become less socially acceptable than in the previous century to refer to African Americans or the Latinx community through derogatory terms or allude to these populations using stereotypes. In the media, popular culture, and everyday dialogue, the majority of the population has reached a consensus to avoid any instance of expressing prejudice that would offend African Americans or Latinx. While this phenomenon of greater social awareness has been largely favorable to the progression of our society, it seems to leave out another minority group in the United States: Asians. Although great lengths have been taken to cease instances of racial biases towards African Americans and Latinos, individuals continue to express overtly racist sentiment towards Asians, especially those of East Asian or Southeast Asian orientation. This phenomenon has been exacerbated greatly by the Covid-19 pandemic.

This paper examines how observed privilege relates to the treatment of Asians in society today through measures of social tolerability and impact of stereotypes on perception. I conjecture a phenomenon in which people feel more comfortable in conveying explicit racism towards Asians than other racial groups, which I theorize occurs because many individuals subconsciously perceive Asian Americans as more advantaged in comparison to other racial minorities along measures of intelligence and economic security. As a result, members of other racial groups feel less inclined to exhibit sympathy or react defensively when someone displays prejudice towards Asian Americans in an everyday social context.

description: Two alternative theories to dark matter are investigated by testing their ability to describe consistently the dynamics of the Milky Way. The first one refers to a modified gravity theory having a running gravitational constant and the second assumes that dark matter halos are constituted by a Bose-Einstein condensation. The parameters of each model as well as those characterizing the stellar subsystems of the Galaxy were estimated by fitting the rotation curve of the Milky Way. Then, using these parameters, the vertical acceleration profile at the solar position was computed and compared with observations. The modified gravity theory overestimates the vertical acceleration derived from stellar kinematics while predictions of the Bose-Einstein condensation halo model are barely consistent with observations. However, a dark matter halo based on a collisionless fluid satisfies our consistency test, being the best model able to describe equally well the rotation curve and the vertical acceleration of the Galaxy.

Physical Vs. Virtual Isolation, Loneliness, and Substance Misuse During COVID-19
Creators: name: Corvin, Caroline
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: The harmful influence of social disconnection on risk of substance misuse is well-researched. However, our study is the first to analyze the interactive effects of isolation and loneliness with the reinforcement models of addiction to assess risk of problematic alcohol and drug use under the COVID-19 pandemic. A sample of young adults (N=144, 58% white, 25% African American, 6% Hispanic) completed a questionnaire evaluating frequency of substance-use related problems, frequency of virtual and face-to-face interaction, motivations for substance use as positive or negative reinforcement, and perceived loneliness. Results indicated that physical, but not virtual, isolation is associated with loneliness; additionally, though women experience more loneliness at low levels of physical isolation, only higher levels of physical isolation were associated with greater loneliness in men. The interaction of loneliness with positive reinforcement motives was associated with greater risk of substance use problems, but similar interaction models of loneliness with either negative reinforcement motives or gender were insignificant, as was the interaction of physical isolation with either reinforcement motives or gender. Lastly, men reported more positive reinforcement motives for drug use, but no gender differences in negative reinforcement motives were found. Future studies should incorporate larger and more diverse samples and should investigate the interaction of isolation and loneliness with other substance use risk factors.

description: The extended Kepler mission, K2, is now providing photometry of new fields every three months in a search for transiting planets. In a recent study, Foreman-Mackey and collaborators presented a list of 36 planet candidates orbiting 31 stars in K2 Campaign 1. In this contribution, we present stellar and planetary properties for all systems. We combine ground-based seeing-limited survey data and adaptive optics imaging with an automated transit analysis scheme to validate 21 candidates as planets, 17 for the first time, and identify 6 candidates as likely false positives. Of particular interest is K2-18 (EPIC 201912552), a bright (K=8.9) M2.8 dwarf hosting a 2.23 \pm 0.25 R_Earth planet with T_eq = 272 \pm 15 K and an orbital period of 33 days. We also present two new open-source software packages which enable this analysis. The first, isochrones, is a flexible tool for fitting theoretical stellar models to observational data to determine stellar properties using a nested sampling scheme to capture the multimodal nature of the posterior distributions of the physical parameters of stars that may plausibly be evolved. The second is vespa, a new general-purpose procedure to calculate false positive probabilities and statistically validate transiting exoplanets.

O objetivo inicial era estabilizar o suporte, preservando assim as informações ainda presentes nos documentos. Havia a necessidade de implementar uma técnica que permitisse o reforço estrutural dos mesmos, proporcionando a menor quantidade de água possível, para limitar o risco de causar deformações e/ou modificar as dimensões dos documentos tratados, uma vez que geralmente são plantas com escala. Com base nas técnicas utilizadas para o tratamento de papel vegetal, optou-se pelo uso da técnica do papel japonês previamente preparado com Klucel G, reativado com álcool, sendo este um adesivo de baixa toxidade e com boa reversibilidade. Esse procedimento apresentou um resultado satisfatório tanto na flexibilidade, quanto na transparência obtida após a aplicação, proporcionando estabilidade ao suporte para ser digitalizado e armazenado com segurança.
Beyond the bodice ripper

description: Romance novels have changed significantly since they first entered the public consciousness. Instead of seeking to understand the changes that have occurred in the industry, in readership, in authorship, and in the romance novel product itself, both academic and popular perception has remained firmly in the early 1980s when many of the surface criticisms were still valid. Using Wendy Griswold’s (2004) idea of a cultural diamond, I analyze the multiple and sometimes overlapping relationships within broader trends in the romance industry based on content analysis and interviews with romance readers and authors. Three major issues emerge from this study. First, content of romance novels sampled from the past fourteen years is more reflective of contemporary ideas of love, sex, and relationships. Second, romance has been a leader and innovator in the trend of electronic publishing, with major independent presses adding to the proliferation of subgenres and pushing the boundaries of what is considered romance. Finally, readers have a complicated relationship with the act of reading romance and what the books mean in their lives. Understanding the enduring appeal of the happily ever after and the emotional escape are central to their enjoyment.
And So We Exist: A Collection of Short Stories

description: This is a collection of creative fiction short stories surrounding various coming-of-age themes such as heartbreak, death, love, and loss. The thirteen stories follow different characters in moments of liminality as they transition from one phase of life to another. If this collection could be tied together by any overarching premise, it would be about the spectrum of relationships humans are able to form, from platonic to familial to romantic, and how all can be of equal value and importance.

The statistical mechanics of planet orbits
Creators: name: Tremaine, Scott

description: The final "giant-impact" phase of terrestrial planet formation is believed to begin with a large number of planetary "embryos" on nearly circular, coplanar orbits. Mutual gravitational interactions gradually excite their eccentricities until their orbits cross and they collide and merge; through this process the number of surviving bodies declines until the system contains a small number of planets on well-separated, stable orbits. In this paper we explore a simple statistical model for the orbit distribution of planets formed by this process, based on the sheared-sheet approximation and the ansatz that the planets explore uniformly all of the stable region of phase space. The model provides analytic predictions for the distribution of eccentricities and semimajor axis differences, correlations between orbital elements of nearby planets, and the complete N-planet distribution function, in terms of a single parameter, the "dynamical temperature", that is determined by the planetary masses. The predicted properties are generally consistent with N-body simulations of the giant-impact phase and with the distribution of semimajor axis differences in the Kepler catalog of extrasolar planets. A similar model may apply to the orbits of giant planets if these orbits are determined mainly by dynamical evolution after the planets have formed and the gas disk has disappeared.

Routes to Succinimide and Pyridine-Substituted Pt(II) Complexes: An Unexpected Pattern of Reactivity
Creators: name: Satkowiak, Lauren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Z-type ligands remove electron density from the metal center, providing tunable electronic control over metal complexes. Based on previous work with silyl-palladium cations, we hypothesize that a mismatch of hard Pt(IV) with a soft iodide ligand may act as a source of iodonium cation, a reactivity profile uncharacteristic of Pt-I bonds. To investigate this, Pt(II) iodide complexes bound to a series of bidentate ligands with varying bite angles and stereoelectronic properties will be reacted with known iodonium sources. Addition of N-iodosuccinimide (NIS) and bis(pyridine)iodonium tetrafluoroborate to Pt(II) starting materials leads to a mono-succinimide/pyridine substituted Pt(II) product with an I3- ligand at one equivalent, and a bis-succinimide/pyridine complex at three equivalents. Unexpectedly, this trend holds true despite changing the ligand identity.

The Role of High-Intensity Interval Training on Anxiety Sensitivity and Self-Efficacy: A Pilot Randomized Controlled Trial

description: Many Americans do not meet the recommended level of aerobic and muscle-strengthening exercise as demonstrated by data from 2018. Furthermore, levels of anxiety are rising in the U.S., particularly in the young adult population. Previous research has shown that levels of physical activity can have an impact on an individual’s mental health. Exercise has been shown to promote higher levels of self-efficacy (SE) and reduce levels of anxiety sensitivity (AS). However, no study has looked at the relationship between exercise interventions, SE, and AS. The goals of this study were to: 1) examine the relative effectiveness of high-intensity interval training (HIIT) versus moderate intensity continuous training (MICT) and static stretching to increasing SE and reducing AS in the short and long-term, and 2) whether SE mediates the relationship between exercise and AS levels. 42 healthy college aged adults with moderate to high AS were randomly assigned to participate in one of three virtual guided exercise interventions: HIIT, MICT, and a static stretching control. Levels of SE and AS were assessed pre-intervention, post-intervention, and 2 weeks after the intervention. All exercise conditions were effective at reducing AS levels, with no significant differences between groups at the post-intervention time point. Significant differences in pre-intervention and 2-week follow-up AS scores were found only in the HIIT group. Significant increases in SE were found in all exercise conditions, and no differences in SE scores between groups were found at any time point. SE was not found to mediate the relationship between exercise and AS. Results highlight the efficacy of using HIIT to produce long-term reductions in AS and the unique trend of changes in AS and SE in the HIIT group. Future directions and limitations are discussed.

description: Boron carbide is an attractive ablator for next-generation inertial confinement fusion (ICF) targets. Here we describe several aspects of our ongoing systematic studies of the deposition and processing of B4C coatings for ICF targets. We show that residual compressive stress in films can be reduced and the deposition rate increased by N-doping. We also demonstrate successful Si substrate etching and surface polishing and discuss remaining challenges and offer potential solutions to the buildup of particulates in the deposition chamber during prolonged coating runs, control of nodular growth defects, and lateral nonuniformity of film properties for deposition conditions with relatively low target-to-substrate distances.

description: The participation of libraries in International Projects has opened a new page in their progress, in the development of the partnership, in the consolidation of the potential, the tendency to transform into the rhythm of the time and to remain as useful in the academic space and beyond. The implementation of these projects brought an influx of new ideas, knowledge, experiences, good practices, mobility, additional funding. The library equipped with this, however, conveys, with certainty, the idea of quality, innovation, present value and time of study.
