description: Water absorption in the metal-organic framework (MOF) material Cu-BTC, up to a concentration of 3.5 H$_2$O per Cu ion, is studied via density functional theory at the meta-GGA+U level. The stable arrangements of water molecules show chains of hydrogen-bonded water molecules and a tendency to form closed cages at high concentration. Water clusters are stabilized primarily by a combination of water-water hydrogen bonding and Cu-water oxygen interactions. Stability is further enhanced by van der Waals interactions, electric field enhancement of water-water bonding, and hydrogen bonding of water to framework oxygens. We hypothesize that the tendency to form such stable clusters explains the particularly strong affinity of water to Cu-BTC and related MOFs with exposed metal sites.

K-Pop Beyond Borders: The Contradictions of Nationalism, Music, and Global Identity
Creators: name: Lee, Erin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This thesis analyzes how K-Pop companies attempt to localize into foreign (non-Korean) markets after 2010 and the market response to these initiatives. The project specifically compares the implementation of strategies pre- and post-THAAD (Terminal High Altitude Area Defense) in China amongst the context of hostile regional geopolitics. By using three case studies of K-Pop idols/groups, this project demonstrates the roles that nationalism and perceptions of identity play in the development of the industry, especially in China. I find that K-Pop idols are tasked with juggling multiple, contradicting identities to balance the needs of different audiences due to the uneasy relationship between international cultural flows and nation-state politics.  In this muddled world of many markets, non-traditional parties in entertainment (state governments, fandoms/online communities) are empowered to enact change in K-Pop due to the Internet and the digital age.

Thoroughbass pedagogy in nineteenth-century Viennese composition and performance practices
Creators: name: Chapman, David F.
Publisher: name: No Publisher Supplied
Year: 2008

description: There is a good deal of recent scholarship concerning the putative demise of thoroughbass practice at the end of the eighteenth century. Not only do many modern scholars view the performance-practice aspects of thoroughbass as having become obsolete by this time, but there is also a prevalent conviction that the pedagogical and compositional aspects of Generalbass had dwindled to the status of a mere mnemonic aid, no longer relevant to the communication of a substantive musical utterance.The purpose of this dissertation is to illuminate the many uses -- theoretical, rhetorical, hermeneutical, and in performance practice -- that this well-established system still enjoyed in the nineteenth century, particularly as utilized and passed along by those within the Viennese sphere of musical endeavor. The fundamental-bass principles that are first codified in the Traité de l'harmonie of Jean-Philippe Rameau (1722) -- and explicated in terms of thoroughbass performance therein -- are later assimilated, with significant modifications, into the theoretical systems of Friedrich Wilhelm Marpurg and Johann Philipp Kirnberger. The confluence of thoroughbass and fundamental-bass practices that the systems of these theorists display is shown to have had a strong influence on a series of important Viennese composers from the beginning of the nineteenth century.The dissertation focuses on two prominent composers of the nineteenth century, Ludwig van Beethoven and Anton Bruckner, and examines their theoretical training in relationship to their compositional output and performance practices. In the course of this discussion, the Generalbass treatises of theorists such as E. A. Förster, Joseph Drechsler, Joseph Preindl, and Ambros Rieder -- all prominent members of the Viennese musical establishment -- are considered. The concepts of Stufentheorie, as put forth by Georg Joseph Vogler and Gottfried Weber, and Funktionstheorie, as advanced in the latter part of the nineteenth century by Hugo Riemann, are also considered in relation to the need for these theorists to explicate their novel concepts to the public at large via the widely understood vehicle of Generalbass notation.
Turks in Germany: Analyzing the Voting Behavior of Germany's Largest Minority
Creators: name: Alvarino, Cassandra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: As of 2021, it is estimated that nearly 3 million people of Turkish descent live in Germany—approximately 3.6% of the population, making it the largest minority group in the country.  Of the 3 million, it is estimated that 1.2 million are eligible to vote—making up roughly 2% of Germany’s voters and more than enough to sway a national election. This thesis looks to understand how German Turks are voting in German elections and what factors are influencing their behavior. This thesis finds that the two most influential factors in determining vote decision for Turkish Germans are: their occupational and income status group and politician's attention to issues concerning racial, ethnic, and religious minority groups.

Functional Analysis of Bloom Syndrome Helicase in Development and DNA Repair
Creators: name: Bereda, Colleen

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

description: Bloom Syndrome is a rare autosomal recessive disorder in humans caused by mutation of the BLM gene that leads to increased genome instability and cancer. The BLM gene codes for a helicase (BLM) that works together with Topoisomerase 3-alpha (Top3α) in homology-directed repair of DNA. Top3α directly binds to BLM and helps release the torsional stress on DNA as BLM unwinds recombination intermediates. These proteins preserve genome stability and have been shown in many organisms to operate together in the prevention of detrimental mitotic (non-meiotic) crossovers via two main DNA repair pathways, synthesis-dependent strand annealing and double Holliday junction dissolution. In Drosophila, BLM (known as Blm) also has roles in proper meiotic chromosome segregation and rapid cell cycle progression of the developing embryo. Each of these BLM functions are not well characterized and limit development of treatments for BLM-related disorders. To investigate the Blm-Top3α interaction in DNA repair, I performed a yeast 2-hybrid (Y2H) assay using the Drosophila genes. I found the interaction was specific to certain regions of Blm, with the strongest interaction observed at a C-terminal region conserved among several Drosophila species, amino acids (aa) 1381-1487. Based on these data, I created specific deletions of the Blm gene via CRISPR/Cas9 editing to characterize the various roles of Blm in vivo. First, I assessed the effects of Blm deletions on known Blm roles in meiotic chromosome segregation via a nondisjunction assay. Both aa 576-720 and N1 produced measurable defects compared to the wild type suggesting functional value of aa 576-720. Significance of this Blm region in preventing mitotic crossovers and DNA repair was evaluated by a crossover assay showcasing a lack of significant effect by aa 576-720 relative to the true null allele, N1, but still increased relative to wild type. These studies showcase the importance of aa 576-720 and other Blm regions in the roles of meiotic segregation and DNA repair. Blm aa 576-720 will be further assessed by examining the relevance of predicted ATR/ATM phosphorylation sites within the region required for proper Blm function. Additional Blm roles in embryonic development will also be explored via an embryo hatching assay. By characterizing the functions of Blm in Drosophila, we will better understand and improve BLM function within humans and the detrimental health effects associated with BLM mutations.

The role of histone H4K20 methylation in recruiting L(3)mbt to chromatin
Creators: name: Butler, Megan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Maintenance of chromatin is essential for proper genome regulation, cell cycle progression, and organismal development. Chromatin structure is often locally established and altered through interactions between histone post-translational modifications and proteins termed “readers,” which recognize these modifications and subsequently affect nearby chromatin. In Drosophila melanogaster, the protein Lethal (3) malignant brain tumor (L(3)mbt) is a known tumor suppressor in larval brains. L(3)mbt contains histone methylation reader domains that may aid in its recruitment to chromatin for transcriptional repression. These reader domains of both the fly and human proteins have previously been shown to preferentially bind histone H4 lysine 20 methylation (H4K20me) in vitro. However, the significance and specificity of L(3)mbt’s reader function in vivo is not well understood, due to inadequate genetic and biochemical tools to assess its role as a reader. Determining whether L(3)mbt depends on H4K20me for binding the genome in vivo has never been addressed in the most direct way – by eliminating H4K20me through mutating H4K20. Using a histone gene replacement platform in Drosophila melanogaster, we generated H4K20A and H4K20R mutants to assess the consequence of eliminating H4K20me on L(3)mbt interaction with the genome. To perform this experiment, we engineered epitope-tagged alleles of endogenous l(3)mbt via CRISPR-Cas9 and the Scarless Gene Editing system. Immunofluorescence with confocal microscopy revealed that, in wildtype animals, L(3)mbt is predominantly nuclear during interphase and does not localize to condensed chromosomes during mitosis, consistent with previous studies. In H4K20-mutant animals, we observed a significant decrease in total L(3)mbt signal. These results suggest that modification of H4K20 is playing a role in L(3)mbt recruitment to chromatin. However, these cytological experiments do not provide adequate resolution to draw specific conclusions regarding the necessity of H4K20me for L(3)mbt chromatin binding. Therefore, we will next use genomics approaches like CUT&RUN to determine the association of these tagged L(3)mbt proteins with chromatin throughout the entire genome in wildtype and H4K20-mutant animals at a high resolution. These data will help to ultimately elucidate a potential mechanism of L(3)mbt’s tumorigenesis.

The Impact of Language on Cross-cultural Emotion Perception: An fMRI Study
Creators: name: Carter, Maleah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Increasingly, research suggests that language plays an important role in emotion perception by facilitating access to emotion-specific semantic knowledge that renders incoming visual information into discernible expressions of emotion. Furthermore, other research shows that cultural differences in emotion-concept knowledge can produce corresponding differences in visual emotion perception. Here, we used fMRI to investigate how priming participants with English emotion-words (i.e., anger, disgust) would influence neural activation during the perception of White, Western-prototypical facial expressions of anger and disgust, as well as how one’s cultural background (i.e., Chinese Native, White American) may influence this activation. We found that relative to White American participants, Chinese Native participants displayed greater activation in regions associated with the use of semantic knowledge such as the right middle temporal gyrus and left inferior frontal gyrus when primed with emotion-words before emotion perception. Across all participants, we found activation in areas linked to language and face processing. These findings suggest a differential benefit of emotion-word priming on the basis of cultural differences and further support the importance of language and access to emotion concepts in emotion perception.

“Zines are Freedom”: Power, Resistance, and Representation in Black Queer Women and Non-binary Folks’ Zines
Creators: name: Daniels, Montia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Popular media have historically represented Black queer people, specifically women, in ways that are problematic and/or incomplete. When Black queer people are excluded from the creative process, these media may perpetuate stereotypes and misrepresentations. Black queer women and transgender folks’ use of zines, however, bridge that gap by putting Black queer people in closer proximity to representations of themselves and their community. This thesis samples two zines—one created by a Black queer woman and the other created by a Black non-binary person—that exemplify a form of Black feminist epistemology as Patricia Hill Collins defines it. These zines provide representations of Black queer people in their own words. Through critical discourse analysis, this thesis considers the ways that Black queer people’s self-representation and the representation of their communities in zines counter mainstream media’s misrepresentation and neglect of Black queer people by providing real and imagined depictions of their lives and experiences.

Is There Room for Environmental Justice in a Sustainable Oslo?  A Discursive Analysis of Sustainability in European Green Cities
Creators: name: Rehder, Sydney
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This paper provides a discursive analysis of justice in sustainable cities, employing archival texts, stakeholder interviews, and field observations. The research investigates if a discursive construction of Oslo, Norway as a sustainable city includes environmental justice. The author identifies major gaps in the goals of European green cities, unearthing a deeper issue: in its current state, “sustainability” is not environmentally just, and therefore is not a helpful framework in creating spaces that are simultaneously just and environmentally conscious. Using Oslo as a case-study, the broader challenges of the sustainable development project in Europe become clear; European cities will continue to grapple with issues of migration and social inclusion until definitions and implementations of sustainability becomes truly just.

A geographic approach to modeling the impact of green roofs on combined sewer overflows in the Bronx
Creators: name: Hartman, Danielle M.
Publisher: name: No Publisher Supplied
Year: 2008

description: The Bronx, New York, like many older urban areas in the United States, suffers from the negative environmental impacts from combined sewer overflows (CSOs). Green roofs have been proposed as a best management practice to reduce stormwater runoff and CSOs. These vegetated roof tops can detain rainfall along with providing other benefits to the building owner and community. This paper describes a green roof stormwater model designed for the Bronx, New York. Building-level geographic data was used to estimate the potential area for green roof implementation in each sewer system subcatchment. A software program was designed as a decision support system with a green roof micro-model, a simple sewer system model, and an interactive map. The model results show that if extensive green roofs were implemented on all available flat roof space, then annual CSOs could be reduced by over 30%. This paper discusses the geographic variation of the model results, and the effectiveness of green roofs as a CSO best management practice is used to rank subcatchment performance.

description: The Kepler satellite has provided photometric timeseries data of unprecedented length, duty cycle and precision. To fully analyse these data for the tens of thousands of stars observed by Kepler, automated methods are a prerequisite. Here we present an automated procedure to determine the period spacing of gravity modes in red-giant stars ascending the red-giant branch. The gravity modes reside in a cavity in the deep interior of the stars and provide information on the conditions in the stellar core. However, for red giants the gravity modes are not directly observable on the surface, hence this method is based on the pressure-gravity mixed modes that present observable features in the Fourier power spectrum. The method presented here is based on the vertical alignment and symmetry of these mixed modes in a period echelle diagram. We find that we can obtain reliable results for both model frequencies and observed frequencies. Additionally, we carried out Monte Carlo tests to obtain realistic uncertainties on the period spacings with different set of oscillation modes (for the models) and uncertainties on the frequencies. Furthermore, this method has been used to improve mode detection and identification of the observed frequencies in an iterative manner.

description: Direct imaging of exoplanets involves the extraction of very faint signals from highly noisy data sets, with noise that often exhibits significant spatial, spectral and temporal correlations. As a results, a large number of post-processing algorithms have been developed in order to optimally decorrelate the signal from the noise. In this paper, we explore four such closely related algorithms, all of which depend heavily on the calculation of covariances between large data sets of imaging data. We discuss the similarities and differences between these methods, and demonstrate how the use sequential calculation techniques can significantly improve their computational efficiencies.

description: We consider the quantum dynamics of a charged particle evolving under the action of a constant homogeneous magnetic field, with emphasis on the discrete subgroups of the Heisenberg group (in the Euclidean case) and of the SL(2, R) group (in the Hyperbolic case). We investigate completeness properties of discrete coherent states associated with higher order Euclidean and hyperbolic Landau levels, partially extending classic results of Perelomov and of Bargmann, Butera, Girardello and Klauder. In the Euclidean case, our results follow from identifying the completeness problem with known results from the theory of Gabor frames. The results for the hyperbolic setting follow by using a combination of methods from coherent states, time-scale analysis and the theory of Fuchsian groups and their associated automorphic forms.

description: The setting of Moessbauer nuclei embedded in thin-film cavities has facilitated an aspiring platform for x-ray quantum optics as shown in several recent experiments. Here, we generalize the theoretical model of this platform that we developed earlier [Phys. Rev. A 88, 043828 (2013)]. The theory description is extended to cover multiple nuclear ensembles and multiple modes in the cavity. While the extensions separately do not lead to qualitatively new features, their combination gives rise to cooperative effects between the different nuclear ensembles and distinct spectral signatures in the observables. A related experiment by Roehlsberger et al. [Nature 482, 199 (2012)] is successfully modeled, the scalings derived with semiclassical methods are reproduced, and a microscopic understanding of the setting is obtained with our quantum mechanical description.

The structural basis of covalent inhibitor stabilization of KDM2A on the nucleosome
Creators: name: Azzam, Dalal
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: To properly store and protect the genome, DNA forms a polymeric complex with histone proteins. The repeating nucleoprotein complex of this polymer is called the nucleosome, the basic structural packaging unit for DNA. The nucleosome is post-translationally modified, which helps to modulate access to the underlying DNA for genome-templated processes. These modifications, such as methylation, write a histone code that controls physiological processes including gene expression, silencing, and cell cycle progression. KDM2A is a histone lysine demethylase that targets histone H3 lysine 36 (H3K36), a residue that, in a demethylated state, is correlated with gene silencing. To understand the molecular basis of H3K36 demethylation by KDM2A, we solved a cryo-EM structure of KDM2A bound to a nucleosome. Initially, we observed that the interaction was very dynamic in nature, resulting in an inability to unambiguously identify a KDM2A binding position on the nucleosome. To stabilize the KDM2A-nucleosome complex, we alkylated a point mutant histone H3K36C with an α-ketoglutarate mimetic, which binds the catalytic pocket of KDM2A (UNC8015). To confirm the binding mechanism between the inhibitor and KDM2A’s catalytic domain, we solved a crystal structure of the complex using X-ray crystallography. The complex consists of the protein’s catalytic domain bound to UNC9076 (a covalent conjugate of the H3(29-41) peptide and UNC8015), which interacts with the peptide binding region of KDM2A and reaches into the catalytic pocket to replace the α-ketoglutarate cofactor. This work aimed to optimize crystal morphology and cryoprotection to improve upon a 2.9 Å dataset of the co-crystal structure of KDM2A/UNC9076 complex. As a direct result of this work, we have solved the 1.98 Å co-crystal structure of the KDM2A/UNC9076 and confirmed its mechanism as a cofactor mimic. The solved structure helps validate the use of a chemical inhibitor to stabilize dynamic protein-nucleosome interactions for cryo-EM.
The Effects of Phytocannabinoids and HIV-1 Tat on Animal Behavior and Microglia-Mediated Neurotoxicity

description: Human immunodeficiency virus type-1 (HIV-1) is associated with high rates of cognitive impairment, anxiety, and pain, likely related to the neuroinflammatory and neurotoxic effects of HIV transactivator of transcription (Tat). Activation of the anti-inflammatory and neuroprotective cannabinoid system, including by the phytocannabinoids Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), may reduce HIV symptoms. However, the specific in vivo and in vitro effects of THC and CBD in the context of Tat require further investigation. We measured the cognition, anxiety, pain sensitivity, and motor activity of male and female Tat-transgenic mice administered varying acute doses of THC and CBD. As microglia-mediated neuroinflammation helps drive Tat toxicity, we also measured the indirect neurotoxicity of microglia treated in primary culture with Tat and CBD. Notable behavioral findings include anxiogenic effects of THC and antinociceptive effects of Tat and THC. Results from cell culture are inconclusive (low sample size) but suggest potentially profound reductions in Tat-induced, microglia-mediated neurotoxicity in the presence of CBD. Other findings and sex differences are discussed.
Infrared spectral and statistical analysis of leaf litter decomposition from the New Jersey Pine Barrens
Creators: name: Lammers, Kristin
Publisher: name: No Publisher Supplied
Year: 2008

description: The soil of the New Jersey Pine Barrens is developed from porous, sandy and acidic deposits. The cycling of mineral nutrients and leaf litter decomposition within this low nutrient environment is important for sustained forest growth. Periodic disturbances through fire can be an important influence on the cycling of nutrients within the ecosystem. The control burns release mineral nutrients, but the changes in the organic composition of leaf litter and soil humus need to be characterized. Fourier-transform infrared spectroscopy (FT-IR) was used to compare the chemistry and chemical changes in composition of leaf litters before and after a fire. Principal component analysis (PCA) of the presence/absence of vibrational modes in addition to differentiated IR spectra revealed changes in the carbohydrate chemistry of leaf litter at each temperature. Analysis of the identical IR data using numerical values gave supplementary and complementary data to the original binary presence and absence. Evolved gas analysis (EGA) was applied to each litter species using Thermal Gravimetric Analysis (TGA-IR) to further characterize the changes induced by heating. EGA indicated that CH, CO2 and CO along with other IR regions of gases evolved while heating from ~225 degrees C to ~600 degrees C. Time series ANOVA verifies different weight loss steps in the IR gaseous regions. FT-IR microspectroscopy highlighted differences between the adaxial and abaxial sides of leaves as well as between undisturbed and decomposed leaves.
Canceled For Now, Not Forever

description: This thesis explores cancel culture on YouTube by conducting a case study on five popular Youtube creators that have been canceled and recovered their platforms. Conclusions in this study are drawn from considering the quantitative data provided by the number of views, likes and dislikes on multiple videos spanning pre-cancellation and post cancellation. Additionally, this study analyzes the comments left on the same videos to determine the general feelings of viewers and the subsequent effect that has on each creator’s platform and level of engagement.

Truck identification using New Jersey weigh in motion data
Creators: name: Donaiah, Amrutha
Publisher: name: No Publisher Supplied
Year: 2008

description: An algorithm for truck identification based on the truck's axle configuration, arrival time, and gross vehicle weight is proposed. The algorithm is applied between WIM Stations and can further be modified for use in Origin-Destination (O-D) studies for New Jersey State. Truck Origin-Destination study is necessary in order to find out if the roads are being used by local state trucks, or by trucks traveling from out of the state. Truck volumes have incomparably increased since past years in the State of NJ reducing the level of safety of pavement structures and highway bridges. An extensive database of WIM data was collected from more than 50 fixed stations throughout the State of NJ. The WIM data collected includes gross weight, axle weights, axle spacings, number of axles, speed, length of the vehicle, vehicle classification and counts, lane, date and time of passage and ESAL's to evaluate truck loading. Truck volumes are highly site specific, depending upon the type of highway and its functionality. Based on the truck's axle spacings, arrival time, and gross vehicle weight, an algorithm is written for monitoring its presence at various WIM Stations. The effect of Weight calibration and other factors on WIM accuracy, and thus on truck identification, are studied. The algorithm was further validated by Spot checking WIM data for the truck presence between stations. Based on the results of this study, it can be concluded that the method followed for truck identification is reliable when applied to stations having accuracy in terms of installation and calibration.However, a rational approach to the whole process of truck identification between WIM stations and O-D study is provided if visual identification systems, like license plate readers, are also adopted as a supplement with WIM data.

description: An exploration of constructed spaces of inclusion and institutional exclusion from a queer perspective. This work explores the representation of the queer body in various historically and epistemologically significant environments related to the queer experience and memory. The first half of the work primarily examines spaces of inclusion, expression, and liberation; whereas the second half of the work attempts to deconstruct myths of American exceptionalism and democratic romanticism in working through spaces tied to queer narratives and cultural attitudes emerging from the Lavender Scare Era.

description: In this paper we consider anomalous dimensions of double trace operators at large spin ($\ell$) and large twist ($τ$) in CFTs in arbitrary dimensions ($d\geq 3$). Using analytic conformal bootstrap methods, we show that the anomalous dimensions are universal in the limit $\ell\gg τ\gg 1$. In the course of the derivation, we extract an approximate closed form expression for the conformal blocks arising in the four point function of identical scalars in any dimension. We compare our results with two different calculations in holography and find perfect agreement.

description: Loopy belief propagation (LBP), which is equivalent to the Bethe approximation in statistical mechanics, is a message-passing-type inference method that is widely used to analyze systems based on Markov random fields (MRFs). In this paper, we propose a message-passing-type method to analytically evaluate the quenched average of LBP in random fields by using the replica cluster variation method. The proposed analytical method is applicable to general pair-wise MRFs with random fields whose distributions differ from each other and can give the quenched averages of the Bethe free energies over random fields, which are consistent with numerical results. The order of its computational cost is equivalent to that of standard LBP. In the latter part of this paper, we describe the application of the proposed method to Bayesian image restoration, in which we observed that our theoretical results are in good agreement with the numerical results for natural images.
