description: Ideas from the theory of multisymplectic systems, introduced recently in integrable systems by the author and Kundu to discuss Liouville integrability in classical field theories with a defect, are applied to the sine-Gordon model. The key ingredient is the introduction of a second Poisson bracket in the theory that allows for a Hamiltonian description of the model that is completely equivalent to the standard one, in the absence of a defect. In the presence of a defect described by frozen Bäcklund transformations, our approach based on the new bracket unifies the various tools used so far to attack the problem. It also gets rid of the known issues related to the evaluation of the Poisson brackets of the defect matrix which involve fields at coinciding space point (the location of the defect). The original Lagrangian approach also finds a nice reinterpretation in terms of the canonical transformation representing the defect conditions.

description: Adverse Childhood Experiences (ACEs) increase developmental vulnerabilities for adult psychopathology, and behavioural addictions in particular. However, our understanding of the common psychological mechanisms underlying various behavioural addictions is currently limited. The present study explores self-report emotion dysregulation and depression severity as candidate transdiagnostic processes for addictions known to be related to ACEs such as gambling, food, and internet (social media) use. A large community sample of working adults (n = 1,231) was surveyed online. Validated self-report assessments of gambling, food, and social media addiction severity were administered. The study found that cumulative ACEs were linked to clinical symptoms of gambling, food, and social media addiction through the mediator of emotion dysregulation. Specific emotion dysregulation mechanisms common to gambling, food, and social media addictions include poor control of impulses when upset, and poor clarity about emotions. Additionally, emotion dysregulation and depression serially mediated the association between ACEs, and food and social media addiction severity. The study specifies emotion- and mood-related clinical targets for clinical assessments and interventions that could benefit adults with a history of ACEs.

Breast Cancer Survivor Narratives on Life After the Conclusion of Active Treatment
Creators: name: Marcom, Sophie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Breast cancer survivors face unique physical and emotional challenges after completing active treatment. This thesis analyzes questionnaires and semi-structured narrative interviews collected from 17 female BCS with the goal of understanding the factors that they deem most significant to their quality of life and identity after completing active treatment. Data was collected through questionnaires and narrative interviews in which participants elaborated on the experience of finishing treatment, finding helpful resources, managing fears of recurrence, changing outlooks and lifestyles, defining survivor identity, and transitioning socially after cancer. Findings suggest that struggles attributed to external factors can be mitigated through improved coordination of care and the creation of empowering transition programs, while personal struggles can be mitigated through the promotion of self-efficacy and resilience in survivorship care and a change in public discourse to better reflect the lived experiences of breast cancer survivors after the end of active treatment.

Systems Biology Approach to PFAS Exposures and Pregnancy-Induced Hypertensive Outcomes
Creators: name: Matthews, Hannah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with pregnancy-induced hypertensive disorders. Despite the regulatory effects in the United States to phase out legacy PFAS, they continue to persist in the environment. This is in part due to the unique chemical and physical properties of these compounds and also the generation of replacement PFAS. The exact cellular mechanisms by which PFAS are associated with hypertensive disorders is not largely understood. Here, we utilized a systems-biology approach to identify and mediate PFAS associated pregnancy-induced hypertensive disorders. Five PFAS: PFOS, PFOA, GenX, PFNA, and PFHxS, were analyzed in silico to predict genes and pathways associated with pregnancy-induced hypertensive disorders. Key molecular players were then assessed in vitro using placental cell lines to evaluate potential molecular pathways mediating the response to PFAS exposure. Further analysis using gene expression microarray technology was completed to assess significant findings in GenX and PFOS. The FAK and retinoate biosynthesis signaling pathways were determined to be the most significant canonical pathways involved in GenX and PFOS exposures respectively. These findings provide novel insights into the key molecular players of PFAS-induced hypertensive disorders and highlight the need for continued efforts to minimize PFAS exposure and prevent associated adverse health outcomes.

description: We present a method for inverting charged particle velocity map images which incoorporates a non-uniform detection function. This method is applied to the specific case of extracting molecular axis alignment from Coulomb explosion imaging probes in which the probe itself has a dependence on molecular orientation which often removes cylindrical symmetry from the experiment and prevents the use of standard inversion techniques for the recovery of the molecular axis distribution. By incorporating the known detection function, it is possible to remove the angular bias of the Coulomb explosion probe process and invert the image to allow quantitative measurement of the degree of molecular axis alignment.

Wind and salinity as drivers of dissolved organic carbon outwelling in two brackish coastal marshes
Creators: name: Emerson, Kayla
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Brackish marshes are coastal wetlands at the interface of land and the ocean. They are productive systems and offer a variety of ecosystem services, including sequestering and outwelling carbon. Coastal marshes are dynamic ecosystems, influenced by the ocean, land, and estuaries surrounding them. The Albemarle Sound is a fresh to brackish water estuary located between the Outer Banks and mainland North Carolina, with Oregon Inlet connecting the Sound to the Atlantic Ocean. Due to little influence from the ocean, the Albemarle Sound experiences wind- driven tides that blow water over marshes at high tide and at low tide, water ebbs off the marsh, expelling dissolved organic carbon (DOC). Within the Albemarle Sound are the smaller Currituck and Croatan Sounds, which differ in their proximity to Oregon Inlet, salinity, and exposure to wind. This study aims to better understand how DOC outwelling in brackish coastal marshes are influenced by wind and salinity. Groundwater wells were installed at different marshes in the Pine Island Audubon Sanctuary on the Currituck Sound to measure water level and salinity. In Fall 2022, water samples and in situ parameters were collected and measured from marshes at the Pine Island Audubon Sanctuary and at the Coastal Studies Institute on the Croatan Sound. These samples were then analyzed for DOC and compared across sites, salinity, and differing wind speeds and directions. The study documented higher DOC concentrations in porewater and surface water than porewater global averages. DOC concentrations varied between sites and on sampling dates. In addition, a correlated and positive relationship was found between high wind events and water level at Pine Island Audubon Sanctuary. This study is a snapshot of the environmental processes and drivers on two different brackish coastal marsh systems in the Albemarle Sound. Findings show that these are dynamic systems that are playing a role in the carbon cycle in the Albemarle Sound as they release DOC into the Atlantic Ocean. I hope that preliminary findings presented here will provide a basis for future research of DOC outwelling and the dynamism of coastal brackish marshes.

description: There are several possible theoretically allowed non-Abelian fractional quantum Hall (FQH) states that could potentially be realized in one- and two- component FQH systems at total filling fraction $ν= n+ 2/3$, for integer $n$. Some of these states even possess quasiparticles with non-Abelian statistics that are powerful enough for universal topological quantum computation, and are thus of particular interest. Here, we initiate a systematic numerical study, using both exact diagonalization and variational Monte Carlo, to investigate the phase diagram of FQH systems at total filling fraction $ν= n+2/3$, including in particular the possibility of the non-Abelian $Z_4$ parafermion state. In $ν= 2/3$ bilayers, we determine the phase diagram as a function of interlayer tunneling and repulsion, finding only three competing Abelian states, without the $Z_4$ state. On the other hand, in single-component systems at $ν= 8/3$, we find that the $Z_4$ parafermion state has significantly higher overlap with the exact ground state than the Laughlin state, together with a larger gap, suggesting that the experimentally observed $ν= 8/3$ state may be non-Abelian. Our results from the two complementary numerical techniques agree well with each other qualitatively.

Polarized Self-Absorption: A potential new method for probing excited states of nuclei
Creators: name: Walton, Nicholas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Photon strength functions are some of the most important and useful properties of nuclei. Their uses range from modeling the synthesis of light and heavy elements in supernovae to the production of medical isotopes to be used in imaging and therapy. However, complete knowledge of all possible decay modes of a nucleus is required before these functions can be calculated. Current methods of probing nuclei, such as nuclear resonance fluorescence (NRF), often fail to find low-energy decays due to exponentially increasing background radiation at low energies. As a result, current knowledge of all possible decays of a nucleus results in a lower limit rather than a definitive value. I seek to probe the reliability of Polarized Self Absorption, a new method proposed for probing nuclei that takes advantage of the quasi-monochromatic and linearly polarized photon beam produced at the High Intensity gamma-ray Source, by examining the 10.71-MeV excited state in 24Mg. Specifically, I work towards finding the full and partial widths of this state in 24Mg. As a first result, this work found new decay paths out of the 10.71-MeV state and determined its spin and parity to be 1^+. The difference between the experimental asymmetry, A_{Ex} = 0.644(5), and the mass-weighed asymmetry, A_{MW} = 0.457(5), indicates that self absorption is taking place, as required for this method to work. However, the final determination of the resonance width will have to await resolution of an issue discussed further in the text.

Por otro lado en las zonas donde hubo riesgo extremo según la Misión de Observación Electoral (MOE), tales como Córdoba, Sucre, Bolívar y Chocó, la participación disminuyó. Teniendo en cuenta la tradición histórica del país, las elecciones al Congreso de este año 2018, han sido las más participativas hasta el momento, desde la constituyente de 1991. En este sentido, el voto de este año reflejó de forma más explícita la opinión de los electores, con influencia de las consultas presidenciales que polarizaron el voto y destacaron la derecha del Centro Democrático e un importante bloque de centro-izquierda.  Por tanto, a través de este documento se realiza un análisis de los resultados de dichas elecciones a nivel general y por partidos.
Spatial Estimation of Radon Exposure for Epidemiologic Risk Assessment
Creators: name: Sorensen, Kyle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Radon is a naturally occurring radioactive gas and is an intermediate product of the decay of uranium. Exposure to radon is the second leading cause of lung cancer in the United States and is hypothesized to cause strokes and other cardiovascular events. Additionally, radon levels seem to be rising across North America and may be linked to climate change. In the early 1990’s, the US EPA created a map of three distinct radon zones, classified according to indoor radon measurements (pCi/L) from the State Residential Radon Survey (SRRS), aerial radioactivity (ppm eU), geology, soil permeability and architecture type called the geologic radon potential (GRP) map. The goal of this analysis is to create an improved, granular spatial model for the geographic distribution of radon based on the SRRS data while accounting for other spatially dependent factors included in the calculation of GRP. The models used in this study include kriging, latent process modeling, LOESS and an ensemble estimation approach. The best model among these in terms of predictive accuracy was the ensemble estimation approach, with a mean absolute error of 2.059 pCi/L when fit to a 3 by 3 coordinate region in middle Tennessee. Future work on this project may include integration of additional data sets, inclusion of a temporal component leveraging more recent radon measurement data, further development of the ensemble estimation approach, accounting for the bias in the sampling design of the SRRS, or incorporating additional modeling approaches such as inverse distance weighted mean and nearest neighboring measure.
Mindful and Loving Resonance: Testing dose-response associations between duration (and frequency) of meditation practice and people’s experiences of positivity resonance with others
Creators: name: White, Avery
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Positivity resonance is a construct used to measure the quality of social connection characterized
by shared positive affect, caring nonverbal synchrony, and biological synchrony. Mindfulness
meditation and loving-kindness meditation have been shown to increase individual positive
affect and social connectedness and therefore may bolster positivity resonance. Using data from
a diverse sample of midlife adults raised in low-SES homes (N=113), we utilize multilevel
models to test the novel hypothesis that participants will report increased positivity resonance as
a function of the duration and frequency of their meditation practice. Participants reported their
frequency and duration of meditation practice daily and completed bi-weekly Day
Reconstruction Method surveys about positivity resonance for 10 weeks, during which they
received 6 weeks of meditation training in either mindfulness or loving-kindness. Contrary to our
predictions, the results of the multilevel models demonstrated a marginal and negative
within-persons association between meditation duration and same-day positivity resonance, and
the same pattern of results held for meditation frequency and positivity resonance. A simple
slopes analysis demonstrated that for participants with higher depression scores, meditating more
frequently than other participants was associated with lower positivity resonance scores.
Exploratory analyses revealed that participants who tended to meditate more than others also
tended to socialize significantly less. These findings suggest there may be trait-level differences
between people who meditate more and those who meditate less, and they indicate a need for
further research into the impacts of meditation practice on positivity resonance.

description: The quantum statistical parton distributions approach proposed more than one decade ago is revisited by considering a larger set of recent and accurate Deep Inelastic Scattering experimental results. It enables us to improve the description of the data by means of a new determination of the parton distributions. This global next-to-leading order QCD analysis leads to a good description of several structure functions, involving unpolarized parton distributions and helicity distributions, in a broad range of $x$ and $Q^2$ and in terms of a rather small number of free parameters. There are several challenging issues and in particular the confirmation of a large positive gluon helicity distribution. The predictions of this theoretical approach will be tested for single-jet production and charge asymmetry in $W^{\pm}$ production in $\bar p p$ and $p p$ collisions up to LHC energies, using recent data and also for forthcoming experimental results.

description: Elemental phosphorous is believed to have several stable allotropes that are energetically nearly degenerate, but chemically reactive. To prevent chemical degradation under ambient conditions, these structures may be capped by monolayers of hexagonal boron nitride ({\em h}-BN) or graphene. We perform {\em ab initio} density functional calculations to simulate scanning tunneling microscopy (STM) images of different layered allotropes of phosphorus and study the effect of capping layers on these images. We find that protective monolayers of insulating {\em h}-BN allow to distinguish between the different structural phases of phosphorus underneath, even though the images are filtered through only nitrogen atoms that appear transparent. No such distinction is possible for phosphorus films capped by semimetallic graphene that masks the underlying structure. Our results suggest that the real-space imaging capability of STM is not hindered by selected capping layers that protect phosphorus surfaces.

description: Compact stars satisfy certain no-hair relations through which their multipole moments are given by their mass, spin and quadrupole moment. These relations are approximately independent of their equation of state, relating pressure to density. Such relations are similar to the black hole no-hair theorems, but these possess event horizons inside which information that led to their formation can hide. Compact stars do not possess horizons, so whether their no-hair relations are related to the black hole ones is unclear. We investigate how the two relations are related by studying relations among multipole moments for compact stars with anisotropic pressure as a toy model, which allows such stars to be more compact than those with isotropic pressure. We here show numerically that the compact star no-hair relations approach the black hole ones as the compactness approaches that of a black hole. We also prove analytically that the current dipole moment exactly reaches the black hole limit quadratically in compactness as strongly-anisotropic stars approach the black hole limit. We moreover show that compact stars become progressively oblate in this limit, even if prolate at low compactness due to strong anisotropies.

description: In the past years, there have been tremendous advances in the field of planar N=4 super Yang-Mills scattering amplitudes. At tree-level they were formulated as Grassmannian integrals and were shown to be invariant under the Yangian of the superconformal algebra psu(2,2|4). Recently, Yangian invariant deformations of these integrals were introduced as a step towards regulated loop-amplitudes. However, in most cases it is still unclear how to evaluate these deformed integrals. In this work, we propose that changing variables to oscillator representations of psu(2,2|4) turns the deformed Grassmannian integrals into certain matrix models. We exemplify our proposal by formulating Yangian invariants with oscillator representations of the non-compact algebra u(p,q) as Grassmannian integrals. These generalize the Brezin-Gross-Witten and Leutwyler-Smilga matrix models. This approach might make elaborate matrix model technology available for the evaluation of Grassmannian integrals. Our invariants also include a matrix model formulation of the u(p,q) R-matrix, which generates non-compact integrable spin chains.

Illumination Space: A Feature Space for Radiance Maps

description: Radiance maps (RM) are used for capturing the lighting properties of real-world environments. Databases of RMs are useful for various rendering applications such as Look Development, live action composition, mixed reality, and machine learning. Such databases are not useful if they cannot be organized in a meaningful way. To address this, we introduce the illumination space, a feature space that arranges RM databases based on illumination properties. We avoid manual labeling by automatically extracting features from an RM that provides a concise and semantically meaningful representation of its typical lighting effects. This is made possible with the following contributions: a method to automatically extract a small set of dominant and ambient lighting properties from RMs, and a low-dimensional (5D) light feature vector summarizing these properties to form the illumination space. Our method is motivated by how the RM illuminates the scene as opposed to describing the textural content of the RM.

description: In this work, we propose an interactive system to design diverse high-quality garment images from fashion sketches and the texture information. The major challenge behind this system is to generate high-quality and detailed texture according to the user-provided texture information. Prior works mainly use the texture patch representation and try to map a small texture patch to a whole garment image, hence unable to generate high-quality details. In contrast, inspired by intrinsic image decomposition, we decompose this task into texture synthesis and shading enhancement. In particular, we propose a novel bi-colored edge texture representation to synthesize textured garment images and a shading enhancer to render shading based on the grayscale edges. The bi-colored edge representation provides simple but effective texture cues and color constraints, so that the details can be better reconstructed. Moreover, with the rendered shading, the synthesized garment image becomes more vivid.

description: This is the first report to describe a role for Lung Kruppel-like Factor (LKLF or KLF2) in inflammatory airways diseases. In the present study, we identify that LKLF is constitutively expressed in the small airways of normal lungs; however, its expression disappears in severe airway diseases, such as cystic fibrosis (CF) and chronic obstructive pulmonary disease. LKLF from primary airway epithelial cells inhibits NF-κB–driven transcription induced by Pseudomonas aeruginosa 7-fold, but is down-regulated in the presence of TNF-α and activated human neutrophils. As a constitutively expressed protein, LKLF inhibits release of a key pro-inflammatory chemokine, IL-8, from airway epithelia. Its expression by lung epithelial cells is enhanced in the presence of TNF blockade. Thus, cytokine-mediated inhibition of LKLF by neutrophils may contribute to ongoing recruitment by promoting IL-8 release from airway epithelia. We conclude that, in neutrophil-dominated airway environments, such as that seen in CF, reduced LKLF activity releases a brake on pro-inflammatory cytokine production and thereby may contribute to the persistent inflammatory responses seen in CF airway disease.

description: Any slight variations in the fundamental constants of Nature, which may be induced by dark matter or some yet-to-be-discovered cosmic field, would characteristically alter the phase of a light beam inside an interferometer, which can be measured extremely precisely. Laser and maser interferometry may be applied to searches for the linear-in-time drift of the fundamental constants, detection of topological defect dark matter through transient-in-time effects and for a relic, coherently oscillating condensate, which consists of scalar dark matter fields, through oscillating effects. Our proposed experiments require either minor or no modifications of existing apparatus, and offer extensive reach into important and unconstrained spaces of physical parameters.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Mental health information is increasingly being disseminated on social media platforms. Content about obsessive-compulsive disorder (OCD) is a popular mental health topic on the social media application TikTok. Our study sought to analyze the content quality of the top 50 TikTok videos about OCD. Raters categorized the videos as “misleading,” “personal experience,” or “useful,” and descriptive information regarding the videos was collected. The Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-A/V) was used to score each video on understandability and actionability. Fifty percent (n=25) of the sample of videos was categorized as personal experience, 26% (n=13)  as useful, and 24% (n=12) as misleading. Inter-rater agreement was 70%. The videos scored high on understandability but low on actionability. Healthcare providers created more useful and actionable videos compared to non-healthcare provider individuals. Clinicians ought to be aware of the widespread misinformation about OCD on social media and its possible effect on clinical care.
Robust model comparison disfavors power law cosmology

description: Late-time power law expansion has been proposed as an alternative to the standard cosmological model and shown to be consistent with some low-redshift data. We test power law expansion against the standard flat $Λ$CDM cosmology using goodness-of-fit and model comparison criteria. We consider Type Ia supernova (SN Ia) data from two current compilations (JLA and Union2.1) along with a current set of baryon acoustic oscillation (BAO) measurements that includes the high-redshift Lyman-$α$ forest measurements from BOSS quasars. We find that neither power law expansion nor $Λ$CDM is strongly preferred over the other when the SN Ia and BAO data are analyzed separately but that power law expansion is strongly disfavored by the combination. We treat the $R_\text{h} = ct$ cosmology (a constant rate of expansion) separately and find that it is conclusively disfavored by all combinations of data that include SN Ia observations and a poor overall fit when systematic errors in the SN Ia measurements are ignored, despite a recent claim to the contrary. We discuss this claim and some concerns regarding hidden model dependence in the SN Ia data.

description: El segundo informe del Observatorio de la Representación Política (ORP)  analiza los resultados de las revocatorias de mandato que se han dado desde las elecciones locales de 2015. Las revocatorias en Colombia, a pesar de su introducción en la Constitución de 1991,  se han realizado desde el año 1996. En el período comprendido entre 1994 y 2017 se han convocado 63 intentos, con un promedio de 2.7 revocatorias por año. Para este resultado se tomaron solo revocatorias que llegaron a fase de votación. Además, resulta interesante resaltar que en 2017,  hasta el 1° de diciembre se han realizado más revotatorias de mandato que en cada uno de los años anteriores. Lo anterior indica que en el 2017 se presentó una ola de revocatorias teniendo en cuenta el promedio.
Revisiting Multi-Component Dark Matter with New AMS-02 Data

description: We revisit the multi-component leptonically decaying dark matter (DM) scenario to explain the possible electron/positron excesses with the recently updated AMS-02 data. We find that both the single- and two-component DM models can fit the positron fraction and $e^+/e^-$ respective fluxes, in which the two-component ones provide better fits. However, for the single-component models, the recent AMS-02 data on the positron fraction limit the DM cutoff to be smaller than 1 TeV, which conflicts with the high-energy behavior of the AMS-02 total $e^++e^-$ flux spectrum, while the two-component DM models do not possess such a problem. We also discuss the constraints from the Fermi-LAT measurement of the diffuse $γ$-ray spectrum. We show that the two-component DM models are consistent with the current DM lifetime bounds. In contrast, the best-fit DM lifetimes in the single-component models are actually excluded.

description: In this paper, we present a monocular 3D fluid volume reconstruction technique that can alleviate challenging parameter tuning while vividly reproducing the inflow and outflow of the video scene. To reconstruct the geometric appearance and 3D motion of the fluid in the video, we propose a multilayer external force guiding model that formulates the effect of target particles on fluid particles. This multilayer model makes the whole 3D fluid volume subject to the shape and motion of the water captured by the input video, so we can avoid tedious and laborious parameter tuning and easily balance the smoothness of the fluid volume and the details of the water surface. Besides, for the inflow and outflow of the 3D fluid volume, we construct a generation and extinction model to add or delete fluid particles according to the 3D velocity field of target particles calculated by a hybrid model of coupling SfS with optical flow. Experiments show that our method compares favorably to the state-of-the-art in terms of reconstruction quality, and is more general to the real-captured fluid. Furthermore, the reconstructed 3D fluid volume can be effectively applied to any desired new scenario.
