description: The sparse representation of signals defined on Euclidean domains has been successfully applied in signal processing. Bringing the power of sparse representations to non-regular domains is still a challenge, but promising approaches have started emerging recently. In this paper, we investigate the problem of sparsely representing discrete surfaces and propose a new representation that is capable of providing tools for solving different geometry processing problems. The sparse discrete surface representation is obtained by combining innovative approaches into an integrated method. First, to deal with irregular mesh domains, we devised a new way to subdivide discrete meshes into a set of patches using a feature-aware seed sampling. Second, we achieve good surface approximation with over-fitting control by combining the power of a continuous global dictionary representation with a modified Orthogonal Marching Pursuit. The discrete surface approximation results produced were able to preserve the shape features while being robust to over-fitting. Our results show that the method is quite promising for applications like surface re-sampling and mesh compression.

Year: 2023

description: The World Health Organization has estimated that 25% of the global population is affected by anemia (World Health Organization 2010). An anemic condition is the result of decreased erythrocytes, decreased hemoglobin, or abnormal hemoglobin structure and is most commonly caused by iron deficiency. Developing countries and, particularly, indigenous groups residing in developing countries are the most negatively impacted by uncontrollable rates of anemia. This study describes the distribution of iron deficiency anemia (IDA) prevalence among the indigenous communities located within Ecuador’s Amazonian basin and investigates the progression of the condition in relation to diet and disease. Statistical analysis of hemoglobin levels, anthropometric measurements and food checklists using data from the Human Biology Lab at the University of North Carolina at Chapel Hill was conducted in order to determine the prevalence of IDA and potential risk factors for the condition. This thesis confirms that IDA is rampant in each of the ethnic groups that make up the indigenous population of Ecuador’s Amazon. Furthermore, this thesis emphasizes that according to the World Health Organization guidelines for public health issues, IDA can be considered a severe public health problem for this population.

description: Folding a thin sheet material such as paper along curves creates a developable surface composed of ruled surface patches. When using such surfaces in design, designers often repeat a process of folding along curves drawn on a sheet and checking the folded shape. Although several methods for constructing such shapes on a computer have been proposed, it is still difficult to check the folded shapes instantly from the crease patterns.In this paper, we propose a simple method that approximately realizes a simulation of curved folds with a triangular mesh from its crease pattern. The proposed method first approximates curves in a crease pattern with polylines and then generates a triangular mesh. In order to construct the discretized developable surface, the edges in the mesh are rearranged so that they align with the estimated rulings. The proposed method is characterized by its simplicity and is implemented on an existing origami simulator that runs in a web browser.

description: A complex Hadamard matrix is a square matrix H with complex entries of absolute value 1 satisfying $HH^*= nI$, where $*$ stands for the Hermitian transpose and I is the identity matrix of order $n$. In this paper, we first determine the image of a certain rational map from the $d$-dimensional complex projective space to $\mathbb{C}^{d(d+1)/2}$. Applying this result with $d=3$, we give constructions of complex Hadamard matrices, and more generally, type-II matrices, in the Bose-Mesner algebra of a certain 3-class symmetric association scheme. In particular, we recover the complex Hadamard matrices of order 15 found by Ada Chan. We compute the Haagerup sets to show inequivalence of resulting type-II matrices, and determine the Nomura algebras to show that the resulting matrices are not decomposable into generalized tensor products.

description: This study investigates the effects of ultra-high light intensities and varying light spectra on the photosynthetic efficiency and growth of maize (Zea mays saccharata). Photosynthetic rates, transpiration, stomatal conductance, and leaf temperature were measured under white light, monochromatic light, and their combinations. Assimilation rates increased with light intensities up to 5000 PAR, plateaued around 5500 PAR, and declined beyond 8000 PAR. Red light at 300 PAR yielded the highest assimilation rate under monochromatic conditions, while green light significantly boosted assimilation at higher intensities, peaking at 33.5 µmol m⁻²s⁻¹ under 4000 PAR. A 50% mix of white and green light at 2000 PAR enhanced assimilation by 14% compared to white light alone. Red light (630 nm) notably promoted photosynthesis in high PAR combinations. However, increasing green light reduced quantum yield, and higher blue light enhanced non-photochemical quenching. These findings suggest that ultra-high light intensities with specific spectral combinations can optimize photosynthesis in maize, though this does not necessarily translate to enhanced overall plant growth.

description: Metagenomics is a powerful approach to study genetic content of environmental samples that has been strongly promoted by NGS technologies. To cope with massive data involved in modern metagenomic projects, recent tools [4, 39] rely on the analysis of k-mers shared between the read to be classified and sampled reference genomes. Within this general framework, we show in this work that spaced seeds provide a significant improvement of classification accuracy as opposed to traditional contiguous k-mers. We support this thesis through a series a different computational experiments, including simulations of large-scale metagenomic projects. Scripts and programs used in this study, as well as supplementary material, are available from http://github.com/gregorykucherov/spaced-seeds-for-metagenomics.

description: Single-dose administration of beta-adrenoceptor agonists produces bronchodilation and inhibits airway hyperresponsiveness (AHR), and is the standard treatment for the acute relief of asthma. However, chronic repetitive administration of beta-adrenoceptor agonists may increase AHR, airway inflammation, and risk of death. Based upon the paradigm shift that occurred with the use of beta-blockers in congestive heart failure, we previously determined that chronic administration of beta-blockers decreased AHR in a murine model of asthma. To elucidate the mechanisms for the beneficial effects of beta-blockers, we examined the effects of chronic administration of several beta-adrenoceptor ligands in a murine model of allergic asthma. Administration of beta-blockers resulted in a reduction in total cell counts, eosinophils, and the cytokines IL-13, IL-10, IL-5, and TGF-β1 in bronchoalveolar lavage, and attenuated epithelial mucin content and morphologic changes. The differences in mucin content also occurred if the beta-blockers were administered only during the ovalbumin challenge phase, but administration of beta-blockers for 7 days was not as effective as administration for 28 days. These results indicate that in a murine model of asthma, chronic administration of beta-blockers reduces inflammation and mucous metaplasia, cardinal features of asthma that may contribute to airflow obstruction and AHR. Similar to heart failure, our results provide a second disease model in which beta-blockers producing an acutely detrimental effect may provide a therapeutically beneficial effect with chronic administration.

description: Low emotional clarity has been a target for psychological interventions due to its association with increased internalising symptoms. However, theory suggests that very high emotional clarity may also lead to increased symptoms, particularly in combination with high levels of neuroticism. As an initial empirical test of this hypothesis, the present study examined curvilinear associations of emotional clarity with internalising symptoms (i.e. dysphoria, social anxiety, panic, traumatic intrusions) and a moderating role of neuroticism/negative affect in the association across two student samples and two clinical samples (total N = 920). Evidence of curvilinear associations and moderation varied across samples, with some supporting evidence in three samples. Specifically, neuroticism/negative affect moderated the curvilinear association of emotional clarity with traumatic intrusions in Clinical Sample 2 as well as the linear association between emotional clarity and dysphoria in Student Sample 2 and Clinical Sample 1. Simple slope analyses indicated that high emotional clarity was not consistently associated with lower symptoms. Also, the hypothesised quadratic effects of emotional clarity were found in Student Sample 2 and Clinical Sample 1 for panic, and in Clinical Sample 1 for dysphoria. Implications and limitations of these findings for conceptualisations of emotional clarity and current treatments were discussed.

description: The classic problems of testing uniformity of and learning a discrete distribution, given access to independent samples from it, are examined under general $\ell_p$ metrics. The intuitions and results often contrast with the classic $\ell_1$ case. For $p > 1$, we can learn and test with a number of samples that is independent of the support size of the distribution: With an $\ell_p$ tolerance $ε$, $O(\max\{ \sqrt{1/ε^q}, 1/ε^2 \})$ samples suffice for testing uniformity and $O(\max\{ 1/ε^q, 1/ε^2\})$ samples suffice for learning, where $q=p/(p-1)$ is the conjugate of $p$. As this parallels the intuition that $O(\sqrt{n})$ and $O(n)$ samples suffice for the $\ell_1$ case, it seems that $1/ε^q$ acts as an upper bound on the "apparent" support size. For some $\ell_p$ metrics, uniformity testing becomes easier over larger supports: a 6-sided die requires fewer trials to test for fairness than a 2-sided coin, and a card-shuffler requires fewer trials than the die. In fact, this inverse dependence on support size holds if and only if $p > \frac{4}{3}$. The uniformity testing algorithm simply thresholds the number of "collisions" or "coincidences" and has an optimal sample complexity up to constant factors for all $1 \leq p \leq 2$. Another algorithm gives order-optimal sample complexity for $\ell_{\infty}$ uniformity testing. Meanwhile, the most natural learning algorithm is shown to have order-optimal sample complexity for all $\ell_p$ metrics. The author thanks Clément Canonne for discussions and contributions to this work.

description: The top-Yukawa-coupling enhanced two-loop corrections to the charged Higgs-boson mass in the real MSSM are presented. The contributing two-loop self-energies are calculated in the Feynman- diagrammatic approach in the gaugeless limit with vanishing external momentum and bottom mass, within a renormalization scheme comprising on-shell and $\overline{\text{DR}}$ conditions. Numerical results illustrate the effect of the $\mathcal{O}{(α_t^2)}$ contributions and the importance of the two-loop corrections to the mass of the charged Higgs bosons.

Absolute Age Determination of the Parks Crossroads Granodiorite of the Carolina Terrane with U-Pb Zircon Geochronology
Creators: name: Morrison, Dylan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: New U-Pb zircon ages for the Parks Crossroads pluton of the Carolina Terrane presented in this study were motivated by the need to reduce age uncertainty in the hope of clarifying the relationship between the pluton and sedimentary rocks in contact with the pluton. Three concordant zircon fractions from the Parks Crossroads Granodiorite yield a weighted mean age of 551.86 ± 0.88 Ma in good agreement with an old Rb-Sr whole rock isochron age. This date suggests that the Parks Crossroads belongs to the Uwharrie Formation of the Albemarle Arc. Furthermore, an inferred maximum depositional age of 534 Ma for the sedimentary unit in contact with the pluton suggests its affinity to the Cid Formation of the Albemarle Arc. These findings demonstrate that the Parks Crossroads pluton is older than the sedimentary unit, and that the two share a disconformable depositional contact rather than an intrusive one, as previously interpreted.

description: We present a new approach for path finding in weighted graphs using pre-computed minimal distance fields. By selecting the most promising minimal distance field at any given node and switching between them, our algorithm tries to find the shortest path. As we show, this approach scales very well for different topologies, hardware and graph sizes and has a mean length error below 1% while using reasonable amounts of memory. By keeping a simple structure and minimal backtracking, we are able to use the same approach on the massively parallel GPU, reducing the run time even further.

description: In this project, we are developing a method to quickly and easily perform video completion. Under the proposed method, the user specifies a target object by drawing a bounding box around it in the first frame of the video; this bounding box is taken as input by SiamMask. SiamMask then tracks the target object and produces its mask in each frame. The resulting masks are then taken as input by Interactive Video Completion, which produces the final video completion result. SiamMask and Interactive Video Completion take several seconds to process an 80-frame video at a pixel resolution of 854x480, i.e., these methods are computationally efficient. The goal of this project is that, after drawing the bounding box, the user immediately obtains the video completion result. However, the mask produced by our current method is not always perfect. When imperfections arise, the user still has to manually modify the mask using an image editing software. We want to improve the quality of automatically produced masks and further reduce the burden of manual modification on the user in the near future.

Diagrammatic Monte Carlo study of mass-imbalanced Fermi-polaron system

Year: 2014

description: We apply the diagrammatic Monte Carlo approach to three-dimensional Fermi-polaron systems with mass-imbalance, where an impurity interacts resonantly with a noninteracting Fermi sea whose atoms have a different mass. This method allows to go beyond frequently used variational techniques by stochastically summing all relevant impurity Feynman diagrams up to a maximum expansion order limited by the sign problem. Polaron energy and quasiparticle residue can be accurately determined over a broad range of impurity masses. Furthermore, the spectral function of an imbalanced polaron demonstrates the stability of the quasiparticle and allows to locate in addition also the repulsive polaron as an excited state. The quantitative exactness of two-particle-hole wave-functions is investigated, resulting in a relative lowering of polaronic energies in the mass-imbalance phase diagram. Tan's contact coefficient for the mass-balanced polaron system is found in good agreement with variational methods. Mass-imbalanced systems can be studied experimentally by ultracold atom mixtures like $^6$Li-$^{40}$K.

“We Believe Limited Government Must Be Uncompromised”- Sometimes. How Traditionalism Contributes to the Inconsistency of The Conservative Belief in Less Government With Respect to Regulation of Abortion, Spending on Crime, and Spending on Defense.

description: For a prolonged period of time in American history, members of the Republican Party have stood behind the idea that the government should have as little involvement in society as possible. Despite this notion, members of the party have advocated for a multitude of policies that directly contradict this ideal. Many people have studied the linkage between the Republican Party and conservatism, the beliefs of conservatives, how traditional values fit into the sphere of conservative politics, and how the Republican Party has changed to embrace specific “big-government” policies over time. However, few have studied why members of the Republican Party have changed their tune of “small government” towards such policies. This research will focus on answering the question of if the reason why Republicans will support larger government involvement in the cases of regulatory power over abortion, spending on crime, and spending on defense is partly due to the level of traditional values they hold. To examine the relationship between the strength of traditional values of Republicans and their propensity toward supporting more government involvement in the three cases mentioned, a series of Chi-Square tests and regressions were conducted. It was found that traditionalism had an impact on how much a Republican wanted the government to spend on crime and defense, as well as whether or not the government should have a regulatory role in denying abortion access. The results from this research paper provide preliminary evidence that certain beliefs and values of Republicans can override the conservative ideal of “small government” in policy-making, and that government size may not be a valid dimension of ideology at all.

description: We present a novel method that reconstructs the Monte Carlo errors of renderings as a blue-noise in screen space. To this end, we conform the statistic result of per-pixel integration to a precomputed blue-noise mask. Thanks to the property of bluenoise, more visual fidelity is achieved through renderings after the reconstruction. The method has two key features. First, its realization is fast and straightforward. Second, it produces stable blue-noise-error renderings regardless of the correlation of the integrands. The preliminary results present robust blue-noise spectra with promising visual improvements in the renderings.

description: In this paper, we are interested in the collective friction of a cloud of particles on the viscous incompressible fluid in which they are moving. The particles velocities are assumed to be given and the fluid is assumed to be driven by the stationary Stokes equations. We consider the limit where the number N of particles goes to infinity with their diameters of order 1/N and their mutual distances of order (1/N)^{1/3}. The rigorous convergence of the fluid velocity to a limit which is solution to a stationary Stokes equation set in the full space but with an extra term, referred to as the Brinkman force, was proven by Desvillettes, Golse and Ricci when the particles are identical spheres in prescribed translations. Our result here is an extension to particles of arbitrary shapes in prescribed translations and rotations. The limit Stokes-Brinkman system involves the particle distribution in position, velocity and shape, through the so-called Stokes' resistance matrices.
Surface Energetics of Alkaline-Earth Metal Oxides: Trends in Stability and Adsorption of Small Molecules

description: We present a systematic theoretical investigation of the surface properties, stability and reactivity, of rock-salt type alkaline-earth metal oxides including MgO, CaO, SrO, and BaO. The accuracy of commonly used exchange-correlation density functionals (LDA, PBE, RPBE, PBEsol, BEEF-vdW and hybrid HSE) and random-phase approximation (RPA) is evaluated and compared to existing experimental values. Calculated surface energies of the four most stable surface facets under vacuum conditions: the (100) surface, the metal and oxygen terminated octopolar (111), and the (110) surfaces exhibit a monotonic increase in stability from MgO to BaO. On the MgO(100) surface, adsorption of CO, NO, CH4 is characterized by physisorption while H2O chemisorbs, which is in agreement with experimental findings. We further use the on-top metal adsorption of CO and NO molecules to map out the surface energetics of each alkaline-earth metal oxide surface. The considered functionals all qualitatively predict similar adsorption energy trends. The ordering between the adsorption energies on different surface facets can be attributed to differences in the local geometrical surface structure and the electronic structure of the metal constituent of the alkaline-earth metal oxide. The striking observation that CO adsorption strength is weaker than NO adsorption on the (100) terraces as the period of the alkaline-earth metal in the oxide increases, is analyzed in detail in terms of charge redistribution within the σ and π channels of adsorbates. Finally, we also present oxygen adsorption and oxygen vacancy formation energies in these oxide systems.

Longitudinal associations among peer and family identity and susceptibility to peer influence
Creators: name: Kreidell, Kennedy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Adolescents are uniquely affected by the influences of both family and peers. As adolescent social identities switch from family-oriented to peer-oriented, it is important to understand how these shifting identities may affect adolescent susceptibility to peer influence. The present study explores the impacts that both family and peer identity individually have on susceptibility to peer influence. 147 adolescents participated across 3 waves at ages 12.32 years, 13.2 years, and 14.23 years. A cross lagged panel analysis revealed that higher susceptibility to peer influence at wave 2 predicted higher peer identity at wave 3. Concurrent analyses indicated that high peer identity predicted low susceptibility to peer influence at wave 1 and high family identity predicted low susceptibility to peer influence at wave 3. Findings have implications for providing context for parents and adolescents about what factors impact their susceptibility to peer influence and how these factors may change over time.

description: In cystic fibrosis (CF), the absence of functional CFTR leads to dysregulated Na+ absorption across airway epithelia. We established an in vitro model of dysregulated Na+ absorption by treating polarized normal human bronchial epithelial cells (HBEs) with nystatin (Nys), a polyene antibiotic that enables monovalent cations to permeate biological membranes. Acute mucosal Nys produced a rapid increase in short circuit current (Isc) that reflected increased transepithelial Na+ absorption and required Na+/K+ATPase activity. The acute increase in Isc was associated with increased mucosal liquid absorption. Prolonged mucosal Nys treatment resulted in sustained Na+ hyperabsorption, associated with increased mucosal liquid absorption in comparison with naïve (nontreated, kept under air–liquid interface conditions) or vehicle-treated cultures. Nys treatment was not toxic. Increased lactate accumulation in Nys-treated culture media suggested a higher metabolic rate associated with the higher energy demand for Na+ transport. After chronic Nys treatment, the increased Isc was rapidly lost when the cultures were mounted in Ussing chambers, indicating that Nys could be rapidly removed from the apical membrane. Importantly, chronic Nys treatment promoted sustained mucosal liquid depletion and caused mucus dehydration, compaction, and adhesion to the apical surface of Nys-treated cultures. We conclude that mucosal Nys treatment of HBEs provides a simple in vitro model to recapitulate the Na+ and volume hyperabsorptive features of CF airway epithelia.

description: An acoustic reverberator consisting of a network of delay lines connected via scattering junctions is proposed. All parameters of the reverberator are derived from physical properties of the enclosure it simulates. It allows for simulation of unequal and frequency-dependent wall absorption, as well as directional sources and microphones. The reverberator renders the first-order reflections exactly, while making progressively coarser approximations of higher-order reflections. The rate of energy decay is close to that obtained with the image method (IM) and consistent with the predictions of Sabine and Eyring equations. The time evolution of the normalized echo density, which was previously shown to be correlated with the perceived texture of reverberation, is also close to that of IM. However, its computational complexity is one to two orders of magnitude lower, comparable to the computational complexity of a feedback delay network (FDN), and its memory requirements are negligible.

description: Minibus transportation is common in Lilongwe, Malawi, however, its role in connecting residences to venues where sex is purchased and sold has not been explored. Measuring connectivity to venues by minibus in Lilongwe is important, as it will help target interventions in highly connected neighborhoods or along bus routes. In this study, we collected minibus routes and brothel locations in Lilongwe and determine the connectivity to these brothels via minibus routes in the city. By focusing on minibus routes, this study describes a previously undescribed transit network that is used to move between residences, brothels, and other venues where sex is sold and purchased. Further, STI clinic studies are often used as sites for interventions focused on reducing STI incidence, however, generalization of these results to the general population is dubious due to clinic attendance mechanisms which could bias the results. The bias in observational studies is referred to as Berkson's Bias which will be elaborated on. Here, we examine the extent to which individuals more connected to the STI clinic and brothels disproportionately attend the STI clinic, offering some clues as to how generalizable trial results in the STI clinic population might be.

description: In the context of un-oriented open string theories, we identify quivers whereby a Majorana mass for the neutron is indirectly generated by exotic instantons. We discuss two classes of (Susy) Standard Model like quivers, depending on the embedding of SU(2)_W in the Chan-Paton group. In both cases, the main mechanism involves a vector-like pair mixing through a non-perturbative mass term. We also discuss possible relations between the phenomenology of Neutron-Antineutron oscillations and LHC physics in these models. In particular, a vector-like pair of color-triplet scalars or color-triplet fermions could be directly detected at LHC, compatibly with n-\bar{n} limits. Finally we briefly comment on Pati-Salam extensions of our models.

description: In the present paper, we consider the Cauchy problem of the system of quadratic derivative nonlinear Schrödinger equations for the spatial dimension $d=2$ and $3$. This system was introduced by M. Colin and T. Colin (2004). The first author obtained some well-posedness results in the Sobolev space $H^{s}$. But under some condition for the coefficient of Laplacian, this result is not optimal. We improve the bilinear estimate by using the nonlinear version of the classical Loomis-Whitney inequality, and prove the well-posedness in $H^s$ for $s\ge 1/2$ if $d=2$, and $s>1/2$ if $d=3$.

description: Currently, heart disease is the leading cause of death in the world. Elevated levels of triglycerides in the bloodstream are a major risk factor for cardiovascular diseases including coronary artery disease. Lipoprotein lipase (LPL) is an enzyme that hydrolyzes large triglyceride-containing lipoprotein particles into free fatty acids that can be taken up by adipose or muscle cells for energy storage or use. LPL activity is inhibited by members of the angiopoietin-like (ANGPTL) protein family, which includes ANGPTL3 and ANGPTL4, both of which can form a multimeric complex with ANGPTL8. While it is known that the ANGPTL3/8 complex is a more potent inhibitor than ANGPTL3 alone, the structure, as well as the mechanism of inhibition of the ANGPTL3/8 complex is not known. In this study, we used mammalian Expi293 cells to co-purify the ANGPTL3/8 complex. Furthermore, we used mass photometry and Size-Exclusion Chromatography with Multi-angle Light Scattering (SEC-MALS) to determine that the oligomeric state of the ANGPTL3/8 complex is in a 3 to 1 ratio of ANGPTL3 to ANGPTL8, respectively. Lastly, we performed an inhibition experiment using very-low-density lipoprotein (VLDL), an endogenous substrate of LPL, and confirmed that the purified ANGPTL3/8 complex inhibits LPL with an IC50 of 6.062 nM. This data can be used to further understand the regulation of triglyceride levels in the blood plasma by LPL and ANGPTL3 and ANGPTL8 and allow for the development of small molecule inhibitors of ANGPTL3/8 to prevent triglyceride accumulation in the blood plasma of patients with defective or reduced LPL.
The impact of advanced age and obesity on response to influenza vaccination

description:  
Background:
        	Obesity is a global health issue, with over 42% of individuals aged 18+ classified as overweight or obese in 2018.1 It has been associated with a host of chronic diseases, such as type 2 diabetes, cardiovascular disease, and cancer.2–4  It has also been associated with impaired immunity.5–8 Historically, increasing age has been associated with increased immune dysfunction. For example, vaccination efficacy is known to be inversely related to age.9  However, there are few studies that have investigated the collective effect age and BMI have on an individual’s immune system.
 
Objective
The study measured the pre and 30 days post-influenza vaccination antibody responses in individuals who were over 65 years of age and were healthy weight, overweight, or obese.
 
Results
Body Mass Index (BMI) and age were negatively correlated with the antibody status among the participants before vaccination. The greatest change in antibody titer post-vaccination was found among individuals who were a healthy weight and younger age. However, there were no significant results that age and BMI collectively have a lower percent change as compared to age and BMI respectively. Additionally, the A/Texas/2012/ virus strain had the lowest percent change between pre and post-vaccination among those with a relatively higher BMI and higher age.
 
Conclusion
The results suggest that there may not be a combinatory decrease in immune response from age and BMI, as age proves to have the greatest effect on immunosenescence. These results also suggest that multiple exposures to a vaccine strain can improve the antibody response in older individuals with a higher BMI.
A CASE STUDY INVESTIGATING CARDIOVASCULAR DISEASE RISK IN ENDOMETRIAL CANCER SURVIVORS: MODERATION BY PERCEIVED DISCRIMINATION

description: Endometrial cancer (EC) is the 4th most common cancer diagnosed in the United States with 75% 10-year survival rates. Despite this high rate of survivorship, the major cause of death among EC survivors is cardiovascular disease (CVD); further, these CVD related deaths disproportionately effect Black EC survivors. The purpose of this case study was to identify differences in CVD risk between black and white endometrial cancer survivors that may be contributing to the racial mortality gap identified by current literature. Participants were eligible if they had a history of type one endometroid cancer, were 50-80 years old, 1-12 months post-treatment, and had a BMI >25 kg/m2 and were recruited in the gynecological oncology clinic at the NC Cancer hospital. Two participants were recruited from the study opening in March 2023. CVD risk was measured via pulse wave velocity values obtained through the Mobil-o-Graph device and compared with the Perceived Discrimination Scale (PDS) and Health-related Quality of Life questionnaire (HRQOL) to better understand impacts of systemic racism. Results were presented as a case study with a special focus on barriers to exercise. Since the opening of the study, 9 of 303 total patients were eligible for this study. Of the 9, 2 subjects enrolled, 3 refused, 3 stated interests in the future, and 1 did not show up to their appointment. Subject 1 was a 76 year old, White, female with a BMI of 27.1 kg/m2. Subject 2 was a 63 year old, Black female with a BMI of 38.6 kg/m2. Subject 2 had a PWV 6.06% greater than subject 1, higher PDS score (difference of 19), and lower HRQOL score (difference of 6) than subject 1. Despite the limited data, the Black EC survivor had higher CVD risk, and more lifetime discrimination than the White EC survivor; however, the Black EC survivor had a lower HRQOL score indicating better quality of life than the White EC survivor. Further research should be conducted to evaluate the racial differences among EC survivors to minimize the racial mortality gap.
