Under the Influence?: Election Law and Redistributive Policy in the United States
Creators: name: Price, Wesley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Drawing on the theoretical perspective that political, and in particular electoral, institutions influence the incentives of policymakers, this study examines the extent to which variation in US state election law is associated with variation in redistributive policy expenditures. In this paper, I utilize time series data from the period 1976-2018 across the 50 states to attempt to empirically assess whether reforms that decrease the political leverage of economic elites or expand the electorate increase the redistributive orientation of the state government. Following those two potential mechanisms––an elite-centered and a mass-based approach––I develop several empirical models to examine the relationship between electoral rules (the stringency of campaign finance law and presence or absence of same-day registration and absentee voting) and the percentage of the state budget devoted to Public Welfare or cash assistance payments as determined by the U.S. Census Annual Survey of State Government Finances. I find evidence under model specifications that do not include time effects to suggest that more stringent campaign finance legislation and no-excuse absentee voting are associated with higher proportions of redistributive expenditures, and that this campaign finance effect is due to restrictions on individual, rather than PAC, contributions. I do not find evidence to support the hypothesis that more lenient registration dates or no-excuse absentee voting are associated with changes in the composition of the electorate overall. However, in no models with time effects are these stated relationships significant.

description: Topological crystalline insulators define a new class of topological insulator phases with gapless surface states protected by crystalline symmetries. In this work, we present a general theory to classify topological crystalline insulator phases based on the representation theory of space groups. Our approach is to directly identify possible nontrivial surface states in a semi-infinite system with a specific surface, of which the symmetry property can be described by 17 two-dimensional space groups. We reproduce the existing results of topological crystalline insulators, such as mirror Chern insulators in the $pm$ or $pmm$ groups, $C_{nv}$ topological insulators in the $p4m$, $p31m$ and $p6m$ groups, and topological nonsymmorphic crystalline insulators in the $pg$ and $pmg$ groups. Aside from these existing results, we also obtain the following new results: (1) there are two integer mirror Chern numbers ($\mathbb{Z}^2$) in the $pm$ group but only one ($\mathbb{Z}$) in the $cm$ or $p3m1$ group for both the spinless and spinful cases; (2) for the $pmm$ ($cmm$) groups, there is no topological classification in the spinless case but $\mathbb{Z}^4$ ($\mathbb{Z}^2$) classifications in the spinful case; (3) we show how topological crystalline insulator phase in the $pg$ group is related to that in the $pm$ group; (4) we identify topological classification of the $p4m$, $p31m$, and $p6m$ for the spinful case; (5) we find topological non-symmorphic crystalline insulators also existing in $pgg$ and $p4g$ groups, which exhibit new features compared to those in $pg$ and $pmg$ groups. We emphasize the importance of the irreducible representations for the states at some specific high-symmetry momenta in the classification of topological crystalline phases. Our theory can serve as a guide for the search of topological crystalline insulator phases in realistic materials.
Mail Survey Study Utilizing Debit Cards and Promised Incentive Methodology
Creators: name: Wardell, Ally
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Abstract
Background: Declining response rates are a persistent problem in survey research. Incentives are the most consistent mechanism for increasing response rates. While there is evidence that incentives contribute to increased response rates, it is unclear how specific nuanced incentive techniques or a combination thereof impact response rates for mail surveys. The process of utilizing VISA debit card is a fairly unstudied process that will be examined in this paper.

Methods: The Chi- Square χ2 test was used to study if the experimental conditions were independent of response. Condition 1 participants were mailed a letter that promised a debit card with an incentive would be mailed to the participant after the completion of a web survey. Condition 2 was provided an empty debit card in a letter promising an incentive would be loaded onto the card after the completion of the survey. Additionally, logistic regression was utilized to study the potential group differences between the response rates and demographic categorical variables. Age, race, ethnicity, education, and gender were analyzed.

Results: The experiment resulted in 204 responses (~27%). There was a significant result of the Chi-Square test for independence, thus there was evidence that may indicate a potential association between incentive type and response to the survey. The only demographic variable that produced a significant response was white vs nonwhite individuals when comparing response rates. For a someone who was a non-white individual, the odds of that person responding to the survey was 0.609 the odds of a white individual responding to the survey.

Conclusion: There is reason to believe that participants who received an empty VISA debit card responded differently than those who did not receive a debit card in their initial survey even though both conditions promised an incentive. Future research must be conducted to further examine this new incentive methodology.

description: We examine the effects of gas-expulsion on initially substructured distributions of stars. We perform N-body simulations of the evolution of these distributions in a static background potential to mimic the gas. We remove the static potential instantaneously to model gas-expulsion. We find that the exact dynamical state of the cluster plays a very strong role in affecting a cluster's survival, especially at early times: they may be entirely destroyed or only weakly affected. We show that knowing both detailed dynamics and relative star-gas distributions can provide a good estimate of the post-gas expulsion state of the cluster, but even knowing these is not an absolute way of determining the survival or otherwise of the cluster.

description: Local electron and ion heating characteristics during merging reconnection startup on the MAST spherical tokamak have been revealed for the first time using a 130 channel YAG-TS system and a new 32 chord ion Doppler tomography diagnostic. 2D local profile measurement of $T_e$, $n_e$ and $T_i$ detect highly localized electron heating at the X point and bulk ion heating downstream. For the push merging experiment under high guide field condition, thick layer of closed flux surface formed by reconnected field sustains the heating profile for more than electron and ion energy relaxation time $τ^E_{ei}\sim4-10$ms, both heating profiles finally form triple peak structure at the X point and downstream. Toroidal guide field mostly contributes the formation of peaked electron heating profile at the X point. The localized heating increases with higher guide field, while bulk downstream ion heating is unaffected by the change in the guide field under MAST conditions ($B_t>3B_{rec}$).

Genetic Normalization Strategy for the Treatment of Pitt-Hopkins Syndrome
Creators: name: Noah, Berens
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Pitt-Hopkins syndrome (PTHS) is a severe neurodevelopmental disorder characterized by developmental delay, hyperactivity, seizures, lack of speech, and high autism comorbidity. Unfortunately, it has no known cure. The pathogenic mechanism in PTHS is decreased protein level of Transcription Factor 4 (TCF4) due to a mutation or deletion in one copy of TCF4. TCF4 is a basic Helix-Loop-Helix (bHLH) transcription factor that regulates hundreds of genes. Consequently, it is nearly impossible to therapeutically address the full phenotypic spectrum of the disorder by targeting downstream molecular pathways. Ideally, PTHS can be treated by normalizing the expression of TCF4, but this strategy has not yet been tested. We took advantage of a mouse model of PTHS (called Tcf4LGSL/+), designed to restore TCF4 expression with temporal precision. We found that reinstating TCF4 expression during embryonic development can restore wild type behavioral phenotypes. However, reinstating TCF4 expression during postnatal development did not lead to phenotypic recovery.

description: We study the dynamics of the half-filled zeroth Landau level of Dirac fermions using mirror symmetry, a supersymmetric duality between certain pairs of $2+1$-dimensional theories. We show that the half-filled zeroth Landau level of a pair of Dirac fermions is dual to a pair of Fermi surfaces of electrically-neutral composite fermions, coupled to an emergent gauge field. Thus, we use supersymmetry to provide a derivation of flux attachment and the emergent Fermi liquid-like state for the lowest Landau level of Dirac fermions. We find that in the dual theory the Coulomb interaction induces a dynamical exponent $z=2$ for the emergent gauge field, making the interactions classically marginal. This enables us to map the problem of $2+1$-dimensional Dirac fermions in a finite transverse magnetic field, interacting via a strong Coulomb interaction, into a perturbatively controlled model. We analyze the resulting low-energy theory using the renormalization group and determine the nature of the BCS interaction in the emergent composite Fermi liquid.

description: We explore the dynamical evolution of a planet embedded in a disk surrounding a star part of a binary system where the orbital plane of the binary is significantly tilted respect to the initial disk plane. Our aim is to test whether the planet remains within the disk and continues to migrate towards the star in a Type I/II mode in spite of the secular perturbations of the companion star. This would explain observed exoplanets with significant inclination respect to the equatorial plane of their host star. We have used two different SPH codes, vine and phantom, to model the evolution of a system star+disk+planet and companion star with time. After an initial coupled evolution, the inclination of the disk and that of the planet begin to differ significantly. The period of oscillation of the disk inclination, respect to the initial plane, is shorter than that of the planet which evolves independently after about 10^4 yr following a perturbed N-body behavior. However, the planet keeps migrating towards the star because during its orbital motion it crosses the disk plane and the friction with the gas causes angular momentum loss. Disk and planet in a significantly inclined binary system are not dynamically coupled for small binary separations but evolve almost independently. The planet abandons the disk and, due to the onset of a significant mutual inclination, it interacts with the gas only when its orbit intersects the disk plane. The drift of the planet towards the star is not due to type I/II with the planet embedded in the disk but to the friction with the gas during the disk crossing.

Sexual Health Education and STD Prevention in Minority Communities in Durham: A Descriptive Cross-Sectional Survey Design Studying a Sexual Health Program
Creators: name: Alexander, Melody
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The prevalence of sexually transmitted diseases (STD’s) is an ongoing public health issue, particularly in the state of North Carolina. While strategies for prevention, treatments, and some cures exist, it remains a concern. North Carolina has consistently ranked in the top ten nationally for gonorrhea, syphilis, and human immunodeficiency virus (HIV) cases, with minority individuals being disproportionately affected (Centers for Disease Control and Prevention [CDC], 2019; North Carolina Institute of Medicine [NCIOM], 2011). The purpose of this project was to assess if attending a sexual health workshop impacted sexual health beliefs, attitudes, and willingness to be screened for STD’s in adults from minority communities in Durham County. Increasing education was selected as an intervention for improving health, based on the health beliefs model (Janz & Becker, 1984). Minority adults (N = 13) residing in Durham County attended a one-time hour and a half long class, and a cross-sectional survey (n = 6) was conducted prior to and following the class. Findings were inconclusive, due to a small sample size and a ceiling effect with the data results. As the maximum or minimum value of the range was selected on the pre-survey, there was no room for upward change or improvement. Future recommendations would be to create a different assessment tool, have resources available in multiple languages, and to obtain a larger sample size. Further research is needed to support the effectiveness of sexual health education on changing sexual health behaviors, while the need for improved sexual health persists.

description: We concisely review the recent evolution in the study of parafermions -- exotic emergent excitations that generalize Majorana fermions and similarly underpin a host of novel phenomena. First we illustrate the intimate connection between Z_3-symmetric "spin" chains and one-dimensional parafermion lattice models, highlighting how the latter host a topological phase featuring protected edge zero modes. We then tour several blueprints for the laboratory realization of parafermion zero modes -- focusing on quantum Hall/superconductor hybrids, quantum Hall bilayers, and two-dimensional topological insulators -- and describe striking experimental fingerprints that they provide. Finally, we discuss how coupled parafermion arrays in quantum Hall architectures yield topological phases that potentially furnish hardware for a universal, intrinsically decoherence-free quantum computer.

description: Suppose that we have a finite colouring of the reals. What sumset-type structures can we hope to find in some colour class? One of our aims is to show that there is such a colouring for which no uncountable set has all of its pairwise sums monochromatic. We also show that there is such a colouring such that there is no infinite set X with X+X (the pairwise sums from X, allowing repetition) monochromatic. These results assume CH. In the other direction, we show that if each colour class is measurable, or each colour class is Baire, then there is an infinite set X (and even an uncountable X, of size the reals) with X+X monochromatic. We also give versions for all of these results for k-wise sums in place of pairwise sums.

description: The Tolman VII solution (an exact static spherically symmetric perfect fluid solution) to the Einstein equations is reexamined, and a closed form equation of state (EOS) is deduced for the first time. This EOS allows further analysis leading to a viable model for compact stars to be obtained. Explicit application of causality conditions places further constraints on the model, and recent measurements of masses and radii of neutron stars prove to be within the predictions of the model. It is found that the adiabatic index $γ \geq 2$, and self-bound crust solutions are not excluded. The solution is also shown to obey known stability criteria. It is argued that this solution provides realistic limits on models of compact stars.

description: The use of object oriented techniques and methodologies for the design of real-time control systems appear to be necessary in order to deal with the increasing complexity of such systems. Recently many object-oriented methods have been used for the modeling and design of real-time control systems. We believe that an approach that integrates the advancements in both object modeling and design methods, and real-time scheduling theory is the key to successful use of object oriented technology for real-time software. However, past approaches to integrate the two either restrict the object models, or do not allow sophisticated schedulability analysis techniques. In this paper we show how schedulability analysis can be integrated with object-oriented design; we develop the schedulability and feasibility analysis method for the external messages that may suffer release jitter due to being dispatched by a tick driven scheduler in real-time control system, and we also develop the scheduliability method for sporadic activities, where message arrive sporadically then execute periodically for some bounded time. This method can be used to cope with timing constraints in complex real-time control systems.

description: Using a void catalog from the SDSS survey, we present the first measurements of void clustering and the corresponding void bias. Over the range 30-200 Mpc/h the void auto-correlation is detected at 5-sigma significance for voids of radius 15-20 Mpc/h. We also measure the void-galaxy cross-correlation at higher signal-to-noise and compare the inferred void bias with the autocorrelation results. Void bias is constant with scale for voids of a given size, but its value falls from 5.6 +/- 1.0 to below zero as the void radius increases from 15 to 30 Mpc/h. The comparison of our measurements with carefully matched galaxy mock catalogs, with no free parameters related to the voids, shows that model predictions can be reliably made for void correlations. We study the dependence of void bias on tracer density and void size with a view to future applications. In combination with our previous lensing measurements of void mass profiles, these clustering measurements provide another step towards using voids as cosmological tracers.

Anti-GPIb and Anti-αIIbβ3 Integrin Antibody Mediated Platelet Depletion in a Murine Model
Creators: name: Bazil, Maximilian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020
Subjects: Thrombocytopenia

description: Platelets are small anucleate cells that circulate in the blood in a quiescent state, function to seal breaches in blood vessels, and prevent blood loss (hemostasis). Thrombocytopenia (low platelet count) can be caused by the production of anti-platelet antibodies (Ab) recognizing platelet surface receptors, such as integrin αIIbβ3 or GPIbα, in a disorder known as immune thrombocytopenia (ITP). In ITP, endogenous antiplatelet antibodies bind to circulating platelets and cause platelet clearance, therefore lowering the platelet count. Interestingly, in mice an anti-αIIbβ3-Ab clone, MWReg30, produces a robust shock response and reduces body temperature, but the anti-GPIbɑ-Ab, R300, does not. Platelet activating factor (PAF) is implicated in anaphylactic shock and PAF receptor inhibitors can reverse hypothermia induced by MWReg30, while maintaining thrombocytopenia. R300 injected into NOD-scid mice (an immuno-compromised strain) caused hypothermia and mortality in a similar manner to MWReg30 in WT mice. The goal of this project was to investigate and compare the mechanisms of Ab-mediated platelet depletion (MWReg30 vs. R300) in WT and NOD-scid mice and determine the cause of R300-induced shock in NOD-scid mice. To visualize Ab-mediated platelet clearance, intravital imaging was performed with scanning confocal microscopy in liver sinusoids of WT and NOD-scid mice treated with either antibody. We observed globular agglutination of platelets during depletion with R300 which differed from the direct binding of single platelets to liver Kupffer cells after treatment with MWReg30. We also aimed to determine the role of PAF in each condition by measuring mast cell activation. We hypothesize that 1) both Abs induce PAF production, but more PAF is produced by administration of MWReg30, and 2) NOD-scid mice may be more sensitive to lower PAF concentrations which could explain the shock response to R300.

description: Providing an early warning of galactic supernova explosions from neutrino signals is important in studying supernova dynamics and neutrino physics. A dedicated supernova trigger system has been designed and installed in the data acquisition system at Daya Bay and integrated into the worldwide Supernova Early Warning System (SNEWS). Daya Bay's unique feature of eight identically-designed detectors deployed in three separate experimental halls makes the trigger system naturally robust against cosmogenic backgrounds, enabling a prompt analysis of online triggers and a tight control of the false-alert rate. The trigger system is estimated to be fully sensitive to 1987A-type supernova bursts throughout most of the Milky Way. The significant gain in sensitivity of the eight-detector configuration over a mass-equivalent single detector is also estimated. The experience of this online trigger system is applicable to future projects with spatially distributed detectors.

description: LHC searches for fermionic top partners $T$ focus on three decay topologies: $T\to bW$, $T\to tZ$, and $T\to th$. However, top partners may carry new conserved quantum numbers that forbid these decays. The simplest possibility is a conserved parity, under which the top partner is odd and all SM states are even. In this case, decays of top partners may involve new particle-odd scalars, leading to signal topologies more commonly associated with supersymmetry, either with or without R-parity conservation. We study a simplified model in which this possibility is realized, and estimate the bounds on the top partner mass in this model implied by LHC searches for supersymmetry. We find that the bounds can be significantly weaker than in the conventional top partner decay scenario. For example, if the new parity is exact, a 500 GeV top partner is allowed as long as the lightest parity-odd scalar mass is between 325 and 500 GeV. The lower allowed top partner mass reduces the need for fine-tuning in the Higgs mass parameter, compared to the conventional decay scenario. We also present an explicit model, the Oddest Little Higgs, which exhibits this phenomenology.

description: We have obtained daily high resolution Echelle spectroscopy of Nova Oph 2015 during its initial evolution. It reveals the presence of pre-existing circumstellar material around the nova, which is best interpreted as the wind of an evolved companion. On earliest observations, the emission line profiles of Nova Oph 2015 displayed a very narrow emission component (FWHM~60 km/s), recombining over a time scale of 5 days and showing constant low velocity (RV_sun= -4.5 km/s), that we interpret as coming from the wind of the secondary recombining after the ionization from the initial UV-flash of the nova. The underlying broad component underwent a marked reduction in both FWHM and width at zero intensity (the latter declining from 4000 to 2000 km/s in ten days) while increasing by 6 times in flux, that we believe is the result of the high velocity ejecta of the nova being slowed down while trying to expand within the surrounding wind of the companion. Novae with evolved secondaries are very rare in the Galaxy, amounting 3% of the total according to recent estimates. Among them Nova Oph 2015 is perhaps unique in having displayed a long rise to maximum brightness and a slow decline from it, a FeII-type classification (contrary to prevailing He/N) and a probable sub-giant luminosity class for the secondary (instead of the giant (e.g. RS Oph) or supergiant (e.g. V407 Cyg) class for the others).

description: In earlier work we showed that a dark matter halo with a virial mass of $10^7$ M$_\odot$ can survive feedback from its own massive stars and form stars for $\gtrsim100$ Myr. We also found that our modelled systems were consistent with observations of ultrafaint dwarfs (UFDs), the least massive known galaxies. Very metal-poor damped Lyman-$α$ systems (DLAs) recently identified at $z\sim2$ may represent the gas that formed at least some of the observed stars in UFDs. We compare projected sightlines from our simulations to the observed metal-poor DLAs and find that our models can reach the densities of the observed sightlines; however the metallicities are inconsistent with the single supernova simulations, suggesting enrichment by multiple supernovae. We model two scenarios for the history of these systems. The first explains the gas abundances in DLAs by a single burst of star formation. This model can produce the observed DLA abundances, but does not provide an explanation as to why the DLAs show suppressed [$α$/Fe] compared to the stellar population of UFDs. The second scenario splits the DLAs into a population which is enriched by a single burst, and a population that is enriched by a second burst after the accretion of metal-poor gas. In this scenario, the suppressed average [$α$/Fe] in DLAs compared to UFDs results from enrichment of second-burst systems by Type Ia supernovae.

description: The Andromeda Galaxy recurrent nova M31N 2008-12a has been caught in eruption nine times. Six observed eruptions in the seven years from 2008 to 2014 suggested a duty cycle of ~1 year, which makes this the most rapidly recurring system known and the leading single-degenerate Type Ia Supernova progenitor candidate; but no 2010 eruption has been found so far. Here we present evidence supporting the recovery of the 2010 eruption, based on archival images taken at and around the time. We detect the 2010 eruption in a pair of images at 2010 Nov 20.52 UT, with a magnitude of m_R = 17.84 +/- 0.19. The sequence of seven eruptions shows significant indications of a duty cycle slightly shorter than one year, which makes successive eruptions occur progressively earlier in the year. We compared three archival X-ray detections with the well observed multi-wavelength light curve of the 2014 eruption to accurately constrain the time of their optical peaks. The results imply that M31N 2008-12a might have in fact a recurrence period of ~6 months (175 +/- 11 days), making it even more exceptional. If this is the case, then we predict that soon two eruptions per year will be observable. Furthermore, we predict the next eruption will occur around late Sep 2015. We encourage additional observations.

description: The coupling of conduction electrons and magnetic textures leads to quantum transport phenomena described by the language of emergent electromagnetic fields [1-3]. For magnetic skyrmions, spin-swirling particle-like objects, an emergent magnetic field is produced by their topological winding [4-6], resulting in the conduction electrons exhibiting the topological Hall effect (THE) [7]. When the skyrmion lattice (SkL) acquires a drift velocity under conduction electron flow, an emergent electric field is also generated [8,9]. The resulting emergent electrodynamics dictate the magnitude of the THE via the relative motion of SkL and conduction electrons. Here, we report the emergent electrodynamics induced by SkL motion in Gd$_2$PdSi$_3$, facilitated by its giant THE [10,11]. With increasing current excitation, we observe the dynamic transition of the SkL motion from the pinned to creep regime and finally to the flow regime, where the THE is totally suppressed. We argue that the Galilean relativity required for the total cancellation of the THE can be generically recovered in the flow regime, even in complex multiband systems such as the present compound. Moreover, the observed THE voltages are large enough to enable real-time measurement of the SkL velocity-current profile, which reveals the inertial-like motion of the SkL in the creep regime, appearing as current-hysteretic behavior of the skyrmion velocity.

description: We present a fresh and broad yet simple approach towards information retrieval in general and diagnostics in particular by applying the theory of complex networks on multidimensional, dynamic images. We demonstrate a successful use of our method with the time series generated from high content thermal imaging videos of patients suffering from the aqueous deficient dry eye (ADDE) disease. Remarkably, network analyses of thermal imaging time series of contact lens users and patients upon whom Laser-Assisted in situ Keratomileusis (Lasik) surgery has been conducted, exhibit pronounced similarity with results obtained from ADDE patients. We also propose a general framework for the transformation of multidimensional images to networks for futuristic biometry. Our approach is general and scalable to other fluctuation-based devices where network parameters derived from fluctuations, act as effective discriminators and diagnostic markers.

The Origins of Civil Terror: The Role of Economic Divisions and Commitment Problems in the Creation of the Syrian Civil War
Creators: name: Tracey Spaugh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: My thesis explores the causes of the Syrian Civil War. I survey the economic changes during the reign of Hafez Al-Assad and his son, Bashar Al-Assad, who ruled the state since 1970.  I explore the role of sectarianism, economic divisions and commitments. Specifically, I highlight the economic liberalization that led to the Arab Spring and the civil war, and the resulting commitment problem that led the Assad regime to start a war to protect its economic and political interests. I show that the war was largely due to the commitment problem and the economic liberalization rather than sectarianism.
