Substrate Specificity of Clinically Relevant Microbial Azoreductases and Structure-Activity Relationships
Creators: name: Carry, Benjamin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Small molecule azobenzene derivatives are ubiquitous compounds and include synthetic dyes used in the food and textile industry, prodrugs for IBD and antibiotic treatment, and many natural compounds. The human azoreductases hNQO1 and hNQO2 have no activity with these substrates, so in vivo processing is entirely reliant on microbial azoreductases (AzoRs) found in the gut. In this investigation we seek to examine the substrate specificity of Class I AzoRs, an effect we expect is driven primarily through steric preferences. We hypothesize that structural subclasses of Class I AzoRs categorized by sequence homology and structural differences will demonstrate differential activities with distinct small-molecule substrates. To begin, we propose a robust methodology for identifying Class I azoreductases through key conserved residues. Using these residues, we identified 215 putative AzoRs from the Integrated Genome Catalog using 12 query sequences of characterized Class I AzoRs. From these novel, putative AzoRs, four were selected for purification and characterization. To demonstrate substrate specificity, the catalytic efficiencies of a panel of the four novel Class I AzoRs, two previously characterized Class I AzoRs, and one representative Class II AzoR with several different Azo dyes was determined. Additional catalytic efficiencies of one AzoR with four key drug targets were also obtained. Finally, crystal structures of one of the novel AzoRs obtained both apo and with FMN cofactor bound were used with the kinetic and phylogenetic results to inform Class I subclasses with different predicted activities based on substrate. Understanding AzoR substrate specificity is critical to both industrial and biologic application, specifically dye-runoff detoxification and improving efficacy of azo-linked 5-ASA IBD treatment.

description: Ridge-like correlations in high-energy proton-proton collisions reported by the CMS collaboration suggest a collective flow that resembles the one in heavy-ion collisions. If the hydrodynamic description is valid then the effect results from the initial anisotropy of the colliding matter which depends on the structure of protons. Following recent theoretical developments, we propose several phenomenological models of the proton structure and calculate the anisotropy coefficients using the Monte Carlo Glauber model. Our estimates suggest that the event multiplicity dependence allows one to discriminate between different proton models.

description: We study global minimizers of a functional modeling the free energy of thin liquid layers over a solid substrate under the combined effect of surface, gravitational, and intermolecular potentials. When the latter ones have a mild repulsive singularity at short ranges, global minimizers are compactly supported and display a microscopic contact angle of $π/2$. Depending on the form of the potential, the macroscopic shape can either be droplet-like or pancake-like, with a transition profile between the two at zero spreading coefficient. These results generalize, complete, and give mathematical rigor to de Gennes' formal discussion of spreading equilibria. Uniqueness and non-uniqueness phenomena are also discussed.

Evaluating and Optimizing Real-Time Software Transactional Memory
Creators: name: Caspin, Shai
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Software transactional memory (STM) is a proposed solution to the challenge of developing correct concurrent code. STM allows programmers to annotate sections of their code that need to be synchronized, and the STM implementation resolves synchronization issues behind the scenes. One application domain where STM can be particularly useful is real-time systems, where schedulability is a crucial metric is system certification. However, STM usually relies on retries to resolve contention, which makes theoretical worst-case behavior, and thus schedulability, highly pessimistic and therefore impractical in the real-time application domain. Previous work on real-time STM has failed to give both theoretical and practical solutions to this problem. Work in this thesis is part of a large effort to present real-time STM that is both schedulable and high-performing, achieved using a retry-free, and thus entirely lock-based, STM implementation. This work details multiple metrics for evaluating retry-free STM compared to a known retry-based lock-based solution, as well as presents optimizations to a locking protocol for increased performance in this context. Evaluations show a retry-free STM implementation with optimized locking protocols is significantly more schedulable and higher performing on single-socket machines than other lock-based STM.
On the automorphisms of the non-split Cartan modular curves of prime level

description: We study the automorphisms of the non-split Cartan modular curves $X_{ns}(p)$ of prime level $p$. We prove that if $p\geq 37$ all the automorphisms preserve the cusps. Furthermore, if $p\equiv 1\text{ mod }12$ and $p\neq 13$, the automorphism group is generated by the modular involution given by the normalizer of a non-split Cartan subgroup of $\text{GL}_2(\mathbb F_p)$. We also prove that for every $p\geq 37$ such that $X_{ns}(p)$ has a CM rational point, the existence of an exceptional rational automorphism would give rise to an exceptional rational point on the modular curve $X_{ns}^+(p)$ associated to the normalizer of a non-split Cartan subgroup of $\text{GL}_2(\mathbb F_p)$.
Sentenced to Die? A Comparison of Factors Leading to Death Sentences and Executions.
Creators: name: Rosenblatt, Tate
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Dozens of researchers have examined legal and extralegal factors that make criminal defendants more likely to receive a death sentence, and substantial evidence suggests that racial biases impact the death sentencing process. However, very few studies have looked at whether these same factors play a role in determining which death sentences are carried out. This thesis investigates that question with three case studies from the southern United States and finds a considerable degree of variation in whether death-sentencing disparities are mitigated, maintained, or amplified by the execution process. One potential explanation for this variation is the varying degrees of discretion that the execution systems in each case study operated with. A subsequent nation-wide analysis supports this explanation by finding that states with lower execution rates have larger racial disparities. The thesis concludes by suggesting a plan for future investigation of factors that influence executions.

description: Context. The Sun is the source of different types of radio bursts that are associated with solar flares, for example. Among the most frequently observed phenomena are type III solar bursts. Their radio images at low frequencies (below 100 MHz) are relatively poorly studied due to the limitations of legacy radio telescopes. Aims. We study the general characteristics of types IIIb and U with stria structure solar radio bursts in the frequency range of 20-80 MHz, in particular the source size and evolution in different altitudes, as well as the velocity and energy of electron beams responsible for their generation. Methods. In this work types IIIb and U with stria structure radio bursts are analyzed using data from the LOFAR telescope including dynamic spectra and imaging observations, as well as data taken in the X-ray range (GOES and RHESSI satellites) and in the extreme ultraviolet (SDO satellite). Results. In this study we determined the source size limited by the actual shape of the contour at particular frequencies of type IIIb and U solar bursts in a relatively wide frequency band from 20 to 80 MHz. Two of the bursts seem to appear at roughly the same place in the studied active region and their source sizes are similar. It is different in the case of another burst, which seems to be related to another part of the magnetic field structure in this active region. The velocities of the electron beams responsible for the generation of the three bursts studied here were also found to be different.

description: Increasing the resolution of a model can improve the performance of a data assimilation system: first because model field are in better agreement with high resolution observations, then the corrections are better sustained and, with ensemble data assimilation, the forecast error covariances are improved. However, resolution increase is associated with a cubical increase of the computational costs. Here we are testing an approach inspired from images super-resolution techniques and called "Super-resolution data assimilation" (SRDA). Starting from a low-resolution forecast, a neural network (NN) emulates a high-resolution field that is then used to assimilate high-resolution observations. We apply the SRDA to a quasi-geostrophic model representing simplified surface ocean dynamics, with a model resolution up to four times lower than the reference high-resolution and we use the Ensemble Kalman Filter data assimilation method. We show that SRDA outperforms the low-resolution data assimilation approach and a SRDA version with cubic spline interpolation instead of NN. The NN's ability to anticipate the systematic differences between low and high resolution model dynamics explains the enhanced performance, for example by correcting the difference of propagation speed of eddies. Increasing the computational cost by 55\% above the LR data assimilation system (using a 25-members ensemble), the SRDA reduces the errors by 40\% making the performance very close to the HR system (16\% larger, compared to 92\% larger for the LR EnKF). The reliability of the ensemble system is not degraded by SRDA.

The climatological relationships between wind and solar energy supply in Britain

description: We use reanalysis data to investigate the daily co-variability of wind and solar irradiance in Britain, and its implications for renewable energy supply balancing. The joint distribution of daily-mean wind speeds and irradiances shows that irradiance has a much stronger seasonal cycle than wind, due to the rotational tilt of the Earth. Irradiance is weakly anticorrelated with wind speed throughout the year ($-0.4 \lesssim ρ\lesssim -0.2$): there is a weak tendency for windy days to be cloudier. This is particularly true in Atlantic-facing regions (western Scotland, south-west England). The east coast of Britain has the weakest anticorrelation, particularly in winter, primarily associated with a relative increase in the frequency of clear-but-windy days. We also consider the variability in total power output from onshore wind turbines and solar photovoltaic panels. In all months, daily variability in total power is always reduced by incorporating solar capacity. The scenario with the least seasonal variability is approximately 70%-solar to 30%-wind. This work emphasises the importance of considering the full distribution of daily behaviour rather than relying on long-term average relationships or correlations. In particular, the anticorrelation between wind and solar power in Britain cannot solely be relied upon to produce a well-balanced energy supply.

description: This thesis looks to explore the viability of wastewater surveillance as a public health tool in the COVID-19 crisis and how it might work to mitigate and control the spread of SARS-CoV-2. This thesis completes an in-depth literature review on works surrounding COVID-19 and wastewater surveillance to unpack its viability as a public health tool. This work analyzes how wastewater surveillance has historically been used during health crises, how it is currently being used both domestically and abroad to fight COVID-19 as well as the advantages and disadvantages of utilizing it over other tools, such as diagnostic testing. Additionally, this work delves into issues surrounding public reception and policy implications as well as important considerations relating to ethics, equity, and legality. For many reasons including cost-effectiveness, efficiency, and the ability to combat gaps left by other interventions, this thesis illustrates the important role of wastewater surveillance and its ability to alter the landscape of the COVID-19 pandemic for the better.
What Makes the Detection of Movement Different within the Au-tistic Traits Spectrum? Evidence from the Audiovisual Depth Paradigm

description: Atypical sensory processing is now considered a diagnostic feature of autism. Although multisensory integration (MSI) may have cascading effects on the development of higher-level skills such as socio-communicative functioning, there is a clear lack of understanding of how autistic individuals integrate multiple sensory inputs. Multisensory dynamic information is a more ecological construct than static stimuli, reflecting naturalistic sensory experiences given that our environment involves moving stimulation of more than one sensory modality at a time. In particular, depth movement informs about crucial social (approaching to interact) and non-social (avoiding threats/collisions) information. As autistic characteristics are distributed on a spectrum over clinical and general populations, our work aimed to explore the multisensory integration of depth cues in the autistic personality spectrum, using a go/no-go detection task. The autistic profile of 38 participants from the general population was assessed using questionnaires extensively used in the literature. Participants performed a detection task of auditory and/or visual depth moving stimuli compared to static stimuli. We found that subjects with high-autistic traits overreacted to depth movement and exhibited faster reaction times to audiovisual cues, particularly when the audiovisual stimuli were looming and/or were presented at a fast speed. These results provide evidence of sensory particularities in people with high-autistic traits and suggest that low-level stages of multisensory integration could operate differently all along the autistic personality spectrum.

description: We demonstrate a new method for the direct measurement of atomic dipole transition matrix elements based on techniques developed for quantum information purposes. The scheme consists of measuring dispersive and absorptive off-resonant light-ion interactions and is applicable to many atomic species. We determine the dipole matrix element pertaining to the Ca II H line, i.e. the 4$^2$S$_{1/2} \leftrightarrow $ 4$^2$P$_{1/2}$ transition of $^{40}$Ca$^+$, for which we find the value 2.8928(43) ea$_0$. Moreover, the method allows us to deduce the lifetime of the 4$^2$P$_{1/2}$ state to be 6.904(26) ns, which is in agreement with predictions from recent theoretical calculations and resolves a longstanding discrepancy between calculated values and experimental results.

The origin of prolate rotation in dwarf spheroidal galaxies formed by mergers of disky dwarfs

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Motivated by the discovery of prolate rotation of stars in Andromeda II, a dwarf spheroidal companion of M31, we study its origin via mergers of disky dwarf galaxies. We simulate merger events between two identical dwarfs changing the initial inclination of their disks with respect to the orbit and the amount of orbital angular momentum. On radial orbits the amount of prolate rotation in the merger remnants correlates strongly with the inclination of the disks and is well understood as due to the conservation of the angular momentum component of the disks along the merger axis. For non-radial orbits prolate rotation may still be produced if the orbital angular momentum is initially not much larger than the intrinsic angular momentum of the disks. The orbital structure of the remnants with significant rotation is dominated by box orbits in the center and long-axis tubes in the outer parts. The frequency analysis of stellar orbits in the plane perpendicular to the major axis reveals the presence of two families roughly corresponding to inner and outer long-axis tubes. The fraction of inner tubes is largest in the remnant forming from disks oriented most vertically initially and is responsible for the boxy shape of the galaxy. We conclude that prolate rotation results from mergers with a variety of initial conditions and no fine tuning is necessary to reproduce this feature. We compare the properties of our merger remnants to those of dwarfs resulting from the tidal stirring scenario and the data for Andromeda II.

description: Different passenger demand rates in transit stations underscore the importance of adopting operational strategies to provide a demand-responsive service. Aiming at improving passengers' travel time, the present study introduces an advanced data-driven optimization approach to determine the optimal stop-skip pattern in urban rail transit lines. In detail, first, using the time-series smart card data for an entire month, we employ a Long Short-Term Memory (LSTM) deep learning model to predict the station-level demand rates for the peak hour. This prediction is based on four preceding hours and is especially important knowing that the true demand rates of the peak hour are posterior information that can be obtained only after the peak hour operation is finished. Moreover, utilizing a real-time prediction instead of assuming fixed demand rates, allows us to account for unexpected real-time changes which can be detrimental to the subsequent analyses. Then, we integrate the output of the LSTM model as an input to an optimization model with the objective of minimizing patrons' total travel time. Considering the exponential nature of the problem, we propose an Ant Colony Optimization technique to solve the problem in a desirable amount of time. Finally, the performance of the proposed models and the solution algorithm is assessed using real case data. The results suggest that the proposed approach can enhance the performance of the service by improving both passengers' in-vehicle time as well as passengers' waiting time.

description: Context. Lithium (Li) is a fragile element that is produced in a variety of sites but can also be very easily depleted in stellar photospheres. Radial migration has been reported to explain the decrease in the upper envelope of Li measurements observed for relatively old metal-rich dwarf stars in some surveys. Aims. We test a scenario in which radial migration could affect the Li abundance pattern of dwarf stars in the solar neighbourhood. This may confirm that the Li abundances in these stars cannot serve as a probe for the Li abundance in the interstellar medium (ISM). In other words, to probe the evolution of the Li abundance in the local ISM, it is crucial that stellar intruders be identified and removed from the adopted sample. Methods. We used the high-quality data (including Li abundances) from the sixth internal Data Release of the Gaia-ESO survey. In this sample we grouped stars by similarity in chemical abundances via hierarchical clustering. Our analysis treats both measured Li abundances and upper limits. Results. The Li envelope of the previously identified radially migrated stars is well below the benchmark meteoritic value (<3.26 dex); the star with the highest detected abundance has A(Li) = 2.76 dex. This confirms the previous trends observed for old dwarf stars (median ages ~ 8 Gyr), where Li decreases for [Fe/H] ≳ 0. Conclusions. This result is supporting evidence that the abundance of Li measured in the upper envelope of old dwarf stars should not be considered a proxy for the ISM Li. Our scenario also indicates that the stellar yields for [M/H] >0 should not be decreased, as recently proposed in the literature. Our study backs recent studies that claim that old dwarfs on the hot side of the dip are efficient probes of the ISM abundance of Li, provided atomic diffusion does not significantly lower the initial Li abundance in the atmospheres of metal-rich objects.

The Impact of Counseling Center Accreditation on Mental Health Policies and Services at Public Universities
Creators: name: Carpenter, Caroline
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: The Center for Collegiate Mental Health (CCMH) has found that use of college counseling services increased by an average of 30-40% between 2009 and 2015, while enrollment increased by only 5% during the same period (2019). Resource allocation for college counseling centers has lagged behind this dramatic increase in usage, causing some institutions
to limit services offered. One accountability mechanism available for college counseling centers in the midst of varying priorities is the accreditation process. The International Accreditation of Counseling Services (IACS) is seen as the premiere institution for setting college counseling standards and accrediting college counseling centers. At eleven public peer institutions, five are accredited by IACS and six are not. This study utilizes a combination of interview data, as well as comparison of counseling center policies and services, to investigate whether accreditation status impacts the policies and services offered at college counseling centers. The policy comparison found that there was no significant difference in compliance to IACS standards between the sample that was accredited versus the sample that was not. Data from interviews with counseling center staff was utilized to contextualize these results and discuss perceived benefits and costs of accreditation. After summarizing the main findings, the conclusion outlines how counseling centers can use this information going forward to assess their own policies and accreditation processes, as well as how further research can expand on details and trends from this study.

description: The important role of geometric phases in searches for a permanent electric dipole moment of the neutron, using Ramsey separated oscillatory field nuclear magnetic resonance, was first noted by Commins and investigated in detail by Pendlebury et al. Their analysis was based on the Bloch equations. In subsequent work using the spin density matrix Lamoreaux and Golub showed the relation between the frequency shifts and the correlation functions of the fields seen by trapped particles in general fields (Redfield theory). More recently we presented a solution of the Schrödinger equation for spin-$1/2$ particles in circular cylindrical traps with smooth walls and exposed to arbitrary fields [Steyerl et al.] Here we extend this work to show how the Redfield theory follows directly from the Schrödinger equation solution. This serves to highlight the conditions of validity of the Redfield theory, a subject of considerable discussion in the literature [e.g., Nicholas et al.] Our results can be applied where the Redfield result no longer holds, such as observation times on the order of or shorter than the correlation time and non-stochastic systems and thus we can illustrate the transient spin dynamics, i.e. the gradual development of the shift with increasing time subsequent to the start of the free precession. We consider systems with rough, diffuse reflecting walls, cylindrical trap geometry with arbitrary cross section, and field perturbations that do not, in the frame of the moving particles, average to zero in time. We show by direct, detailed, calculation the agreement of the results from the Schrödinger equation with the Redfield theory for the cases of a rectangular cell with specular walls and of a circular cell with diffuse reflecting walls.

description: This paper investigates how retailers at different stages of e-commerce maturity evaluate their entry to e-commerce activities. The study was conducted using qualitative approach interviewing 16 retailers in Saudi Arabia. It comes up with 22 factors that are believed the most influencing factors for retailers in Saudi Arabia. Interestingly, there seem to be differences between retailers in companies at different maturity stages in terms of having different attitudes regarding the issues of using e-commerce. The businesses that have reached a high stage of e-commerce maturity provide practical evidence of positive and optimistic attitudes and practices regarding use of e-commerce, whereas the businesses that have not reached higher levels of maturity provide practical evidence of more negative and pessimistic attitudes and practices. The study, therefore, should contribute to efforts leading to greater e-commerce development in Saudi Arabia and other countries with similar context.
Il paesaggio della transumanza in Piemonte: un “patrimonio” che produce alimenti in modo sostenibile
Creators: name: Battaglini, Luca
Publisher: name: Re|Cibo
Year: 2024

description: La valenza culturale del paesaggio, ancora presente in contesti montani e creato dagli allevamenti transumanti, è espressione della permanenza di manufatti e dell’interpretazione degli «ecofatti» (Tosco, 2013). Si tratta di fenomeni originati dall’azione di forze naturali che hanno interagito storicamente con la presenza dell’uomo. Gli ambienti pastorali sono appunto il risultato di un lungo processo di interazione tra uomo e natura, tra pratiche di governo del territorio e dinamiche ecologiche

description: Threshold aggregation reporting systems promise a practical, privacy-preserving solution for developers to learn how their applications are used "\emph{in-the-wild}". Unfortunately, proposed systems to date prove impractical for wide scale adoption, suffering from a combination of requiring: \emph{i)} prohibitive trust assumptions; \emph{ii)} high computation costs; or \emph{iii)} massive user bases. As a result, adoption of truly-private approaches has been limited to only a small number of enormous (and enormously costly) projects. In this work, we improve the state of private data collection by proposing $\mathsf{STAR}$, a highly efficient, easily deployable system for providing cryptographically-enforced $κ$-anonymity protections on user data collection. The $\mathsf{STAR}$ protocol is easy to implement and cheap to run, all while providing privacy properties similar to, or exceeding the current state-of-the-art. Measurements of our open-source implementation of $\mathsf{STAR}$ find that it is $1773\times$ quicker, requires $62.4\times$ less communication, and is $24\times$ cheaper to run than the existing state-of-the-art.
Keeping the Human in Digital Humanities: A Twitter Case Study
Creators: name: Kruchten, Danielle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: 	The rapid expansion of digital humanities has led to questions about how best to define this emerging field and how to harness the new approaches to knowledge that it offers. In this thesis, I explore key characteristics of digital humanities. I also hope to show ways that digital humanities methods can be applied with a case study related to vaccine conversations on Twitter. I will first discuss three key characteristics of digital humanities: interdisciplinarity, collaboration, and democratization. Next, I will explore how these characteristics influence the activities of this field, particularly the ways that computers and programs (machines) relate to humans through intellectual work. Finally, I will apply what I have discussed to analyze Twitter conversations with the hashtags, #vaccines, #vaccineswork, and #antivaxx. The goal is to use digital humanities approaches to understand how vaccine rhetoric is used on the internet and how misinformation can be spread.
Sensitivity to light weakly-coupled new physics at the precision frontier

description: Precision measurements of rare particle physics phenomena (flavor oscillations and decays, electric dipole moments, etc.) are often sensitive to the effects of new physics encoded in higher-dimensional operators with Wilson coefficients given by ${\rm C}/(Λ_{\rm NP})^n$, where C is dimensionless, $n\geq 1$, and $Λ_{\rm NP}$ is an energy scale. Many extensions of the Standard Model predict that $Λ_{\rm NP} $ should be at the electroweak scale or above, and the search for new short-distance physics is often stated as the primary goal of experiments at the precision frontier. In rather general terms, we investigate the alternative possibility: ${\rm C} \ll 1$, and $Λ_{\rm NP} \ll m_W$, to identify classes of precision measurements sensitive to light new physics (hidden sectors) that do not require an ultraviolet completion with additional states at or above the electroweak scale. We find that hadronic electric dipole moments, lepton number and flavor violation, non-universality, as well as lepton $g-2$ can be induced at interesting levels by hidden sectors with light degrees of freedom. In contrast, many hadronic flavor- and baryon number-violating observables, and precision probes of charged currents, typically require new physics with $Λ_{\rm NP} \gtrsim m_W$. Among the leptonic observables, we find that a non-zero electron electric dipole moment near the current level of sensitivity would point to the existence of new physics at or above the electroweak scale.
