Publisher: name: arXiv
Year: 2015
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: Classification results for complex Riemannian foliations are obtained. For open subsets of irreducible Hermitian symmetric spaces of compact type, where one has explicit control over the curvature tensor, we completely classify such foliations by studying the infinitesimal model associated to the canonical connection. We also establish results for symmetric spaces of non-compact type and a general rigidity result for any irreducible Kähler manifold.
description: V3: Added Publication details. Manuscript differs very slightly from published version as a typographical error in line 3 of Table 1 (of V2) is corrected. This means that one of the cases ruled out in Table 2 (of V2) does not need to be considered. Consequently lines 14--16 of page 15 (of V2) were slightly modified to take this into account. The rest of the paper is unaffected
Boosted dark matter from diffuse supernova neutrinos

description: The XENON collaboration recently reported an excess of electron recoil events in the low energy region with a significance of around $3.3σ$. An explanation of this excess in terms of thermal dark matter seems challenging. We propose a scenario where dark matter in the Milky Way halo gets boosted as a result of scattering with the diffuse supernova neutrino background. This interaction can accelerate the dark-matter to semi-relativistic velocities, and this flux, in turn, can scatter with the electrons in the detector, thereby providing a much better fit to the data. We identify regions in the parameter space of dark-matter mass and interaction cross-section which satisfy the excess. Furthermore, considering the data only hypothesis, we also impose bounds on the dark-matter scattering cross-section, which are competitive with bounds from other experiments.

description: Taking a groupoid C*-algebra approach to the study of the quantum complex projective spaces $\mathbb{P}^{n}\left( \mathcal{T}\right) $ constructed from the multipullback quantum spheres introduced by Hajac and collaborators, we analyze the structure of the C*-algebra $C\left( \mathbb{P}^{1}\left( \mathcal{T}\right) \right) $ realized as a concrete groupoid C*-algebra, and find its $K$-groups. Furthermore after a complete classification of the unitary equivalence classes of projections or equivalently the isomorphism classes of finitely generated projective modules over the C*-algebra $C\left( \mathbb{P}^{1}\left( \mathcal{T}\right) \right) $, we identify those quantum principal $U\left( 1\right) $-bundles introduced by Hajac and collaborators among the projections classified.

description: We determine the exact dynamics of an initial Bardeen-Cooper-Schrieffer (BCS) state of ultra-cold atoms in a deep hexagonal optical lattice. The dynamical evolution is triggered by a quench of the lattice potential, such that the interaction strength $U_f$ is much larger than the hopping amplitude $J_f$. The quench initiates collective oscillations with frequency $|U_f|/(2π)$ in the momentum occupation numbers and imprints an oscillating phase with the same frequency on the BCS order parameter $Δ$. The oscillation frequency of $Δ$ is not reproduced by treating the time evolution in mean-field theory. In our theory, the momentum noise (i.e. density-density) correlation functions oscillate at frequency $|U_f|/2π$ as well as at its second harmonic. For a very deep lattice, with zero tunneling energy, the oscillations of momentum occupation numbers are undamped. Non-zero tunneling after the quench leads to dephasing of the different momentum modes and a subsequent damping of the oscillations. The damping occurs even for a finite-temperature initial BCS state, but not for a non-interacting Fermi gas. Furthermore, damping is stronger for larger order parameter and may therefore be used as a signature of the BCS state. Finally, our theory shows that the noise correlation functions in a honeycomb lattice will develop strong anti-correlations near the Dirac point.

description: Since most machine learning (ML) algorithms are designed for numerical inputs, efficiently encoding categorical variables is a crucial aspect in data analysis. A common problem are high cardinality features, i.e. unordered categorical predictor variables with a high number of levels. We study techniques that yield numeric representations of categorical variables which can then be used in subsequent ML applications. We focus on the impact of these techniques on a subsequent algorithm's predictive performance, and -- if possible -- derive best practices on when to use which technique. We conducted a large-scale benchmark experiment, where we compared different encoding strategies together with five ML algorithms (lasso, random forest, gradient boosting, k-nearest neighbors, support vector machine) using datasets from regression, binary- and multiclass- classification settings. In our study, regularized versions of target encoding (i.e. using target predictions based on the feature levels in the training set as a new numerical feature) consistently provided the best results. Traditionally widely used encodings that make unreasonable assumptions to map levels to integers (e.g. integer encoding) or to reduce the number of levels (possibly based on target information, e.g. leaf encoding) before creating binary indicator variables (one-hot or dummy encoding) were not as effective in comparison.

description: This article studies a portfolio optimization problem, where the market consisting of several stocks is modeled by a multi-dimensional jump-diffusion process with age-dependent semi-Markov modulated coefficients. We study risk sensitive portfolio optimization on the finite time horizon. We study the problem by using a probabilistic approach to establish the existence and uniqueness of the classical solution to the corresponding Hamilton-Jacobi-Bellman (HJB) equation. We also implement a numerical scheme to investigate the behavior of solutions for different values of the initial portfolio wealth, the maturity, and the risk of aversion parameter.

The unique role of polymerase μ in nonhomologous end joining
Creators: name: Davis, Bryan Joseph
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Nonhomologous end-joining (NEHJ) has the challenge of repairing DNA double strand breaks (DSBs) without using an intact template molecule to instruct synthesis. NHEJ solves this problem in part by recruiting polymerases from the pol X family to fill gaps that are present at some DSBs. If a gap has some complementary bases, multiple pol X family members can participate in NHEJ, but only pol μ is able to fill the gap if the DNA ends are noncomplementary. I determined that pol μ fills these gaps in a template-directed way, successfully using as template a DNA strand that is not annealed to the primer. My results show pol μ is able to do this because it interacts with DNA on both sides of the gap. Further, I demonstrate that the polymerase is most efficient when it participates in such an end-bridging complex. I then determined the roles of two amino acid residues in pol μ's activity on noncomplementary ends. As a similar residue does in TdT, H329 helps pol μ stabilize the incoming nucleotide when the template strand does not. However, unlike TdT, I show pol μ is not promiscuously template independent. I argue this is in part because pol μ also possesses an element of the more canonical template dependent pol X family members. R175 is part of the 8 kDa domain and helps position the template opposite the primer terminus through an interaction with the downstream phosphate. Pol μ is the only polymerase that has both of these elements and the combination confers the unique ability to fill gaps between noncomplementary ends.

description: As a global pandemic, COVID-19 has resulted in a variety of different epidemiological, cultural, political, and socio-economic impacts. However, similar to other disasters, COVID-19 is disproportionately impacting particular groups, including vulnerable populations. In this paper, the authors examine how there is a need to understand the concept of vulnerability and the information needs of vulnerable individuals, groups and communities through an intersectional lens in order to develop inclusive communication that is accessible to different groups. Two-way communication and ongoing interaction are a necessary step in ensuring that vulnerable groups are not excluded from COVID-19 communication practices, potentially further increasing their vulnerability.

description: Using non-equilibrium molecular dynamics simulations, it has been recently demonstrated that water molecules align in response to an imposed temperature gradient, resulting in an effective electric field. Here, we investigate how thermally induced fields depend on the underlying treatment of long-ranged interactions. For the short-ranged Wolf method and Ewald summation, we find the peak strength of the field to range between $2 \times 10^7$ and $5 \times 10^7~\text{V/m}$ for a temperature gradient of $5.2~\text{K/}\unicode{x212B}$. Our value for the Wolf method is therefore an order of magnitude lower than the literature value [J. Chem. Phys. 139, 014504 (2013) and 143, 036101 (2015)]. We show that this discrepancy can be traced back to the use of an incorrect kernel in the calculation of the electrostatic field. More seriously, we find that the Wolf method fails to predict correct molecular orientations, resulting in dipole densities with opposite sign to those computed using Ewald summation. By considering two different multipole expansions, we show that, for inhomogeneous polarisations, the quadrupole contribution can be significant and even outweigh the dipole contribution to the field. Finally, we propose a more accurate way of calculating the electrostatic potential and the field. In particular, we show that averaging the microscopic field analytically to obtain the macroscopic Maxwell field reduces the error bars by up to an order of magnitude. As a consequence, the simulation times required to reach a given statistical accuracy decrease by up to two orders of magnitude.

Epigenetic Factors Are Dynamically Regulated Throughout The Cell Cycle And Are Required For Efficient DNA Replication
Creators: name: Rizzardi, Lindsay Faircloth
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Chromatin consists of DNA wrapped around a core of histone proteins that can be modified to elicit distinct cellular responses. All DNA-templated processes including DNA replication must function within the context of chromatin. The focus of this study is the interaction between the replication machinery and the chromatin structure it must traverse to faithfully replicate the genome. Individual histone modifications can promote recruitment of replication proteins directly or recruit chromatin remodelers that increase the accessibility of the underlying DNA. Our studies in budding yeast, Saccharomyces cerevisiae, have identified a specific histone modification, H3K4me2, that promotes efficient DNA replication; although, the mechanism of this regulation remains unclear. Additionally, we found that the enzyme responsible for depositing H3K4me2 is cell cycle regulated, being most abundant during G1 when cells prepare the genome for DNA replication. Another histone modification required during G1 for proper DNA replication is H4K20me1. As this modification is not found in budding yeast, our studies were undertaken in a mammalian cell culture system. The enzyme responsible for this modification had previously been identified as Set8 (a.k.a. PR-Set7) and we have begun investigating the regulation of this enzyme throughout the cell cycle and during a cellular stress response. This enzyme is degraded both during S phase and after UV-induced DNA damage by the CRL4Cdt2 E3 ubiquitin ligase complex. We discovered that this degradation after DNA damage is abrogated during mitosis and after osmotic stress. This mechanism is conserved for at least one other CRL4Cdt2 substrate, Cdt1, that is an essential replication factor. Protection from UV-induced degradation requires active Cdk1 during mitosis as inhibition of this kinase leads to degradation of both Set8 and Cdt1. We are currently investigating whether this is a direct or indirect effect. During osmotic stress in asynchronous cells, the stress MAPKs p38 and JNK may play a more important role than Cdk1. It is clear that the histone modifications and the enzymes responsible for their deposition are critical components ensuring proper DNA replication and as such are tightly regulated. Future work will elucidate the exact mechanisms by which these chromatin factors influence DNA replication.
Functional Imaging of Central Mechanisms Underlying Human Pain Perception

description: Investigations of human somatosensory perception have demonstrated robust interactions between the submodalities of pain and touch, and there is increasing recognition that the systematic assessment of somatosensory perception in disorders characterized by persistent pain such as Temporomandibular Disorder (TMD) would greatly aid diagnosis and evaluation of treatment efficacy. To better understand the pathophysiological mechanisms underlying TMD, we investigated cortical processing interactions that occur between innocuous and noxious cutaneous input using functional magnetic resonance imaging (fMRI). Innocuous vibrotactile stimulation and noxious skin heating were delivered separately and concurrently to the hand of women with TMD and to pain-free, gender-matched controls (HC). Cortical responses evoked by innocuous vibrotactile stimulation alone differentiated TMDs from HCs, and the differences between the groups suggest cortical plasticity in TMD which primes areas to respond to innocuous vibrotactile input that normally would not, including parts of the pain matrix and auditory cortex. In contrast, pain ratings and cortical responses to noxious heat alone did not differ significantly between TMDs and HCs. However, additional group differences emerged in the cortical patterns characterizing interactions between somatosensory submodalities in subjects with and without TMD during concurrent stimulation that could not be explained exclusively by group differences in the response to innocuous vibrotactile stimulation. Some of these differences in the interaction of innocuous and noxious somatosensory inputs were correlated with the severity of the TMD patients' clinical pain despite the fact that no significant correlations were observed between TMD pain and responses to vibrotactile or noxious heat stimulation alone. This suggests that cortical processing interactions between somatosensory submodalities more closely reflect individual experiences of persistent clinical pain than does the unimodal processing of innocuous vibrotactile or noxious heat input alone.

Refraction and ocular dimensions were measured per week with handheld streak retinoscopy (66 Vision-Tech Co., Ltd., Suzhou, Jiangsu Province, China) and A-scan ultrasonography with a probe of 10 MHz (KN-1800; Kangning Medical Device Co., Ltd., Wuxi, Jiangsu Province, China) respectively. Changes in ocular dimensions and refractions were analyzed by paired t-tests, and differences among the groups were analyzed by one-way ANOVA. This experiment was carried out in accordance with the ARVO Statement for the Use of Animals in Ophthalmic and Vision Research and was approved by the animal experimentation ethics committee of the Zhongshan Ophthalmic Center.
Virtuous citizens and sentimental society: ethics and politics in neoliberal South Korea

description: This dissertation argues that while South Korea's developmentalist regime prior to the democracy struggles in the 1980s focused on the economic dimension of Korean social life, with the rise of civil society into the democratic era, it is the moral dimension of development that has been emphasized. I explore this project of moral development through the activities of migrant centers that have provided social, legal, and medical services to foreign migrants and acted as their main advocates since the 1990s. Based on ethnographic and archival research, this dissertation focuses on the new social and ethical landscape created by the issue of foreign workers, marriage immigrants, and multicultural families. First, I examine the problem of the human rights of the foreign worker, which essentially relied on the advocacy work by civil society groups such as migrant centers in the absence of the state's interest in protecting them. While the moral welfare of foreign workers became dependent on the benevolence and philanthropic activities of caring volunteer-citizens, the issue of foreign workers has become a matter of maintaining the moral integrity to the history of Korea's own emigration as well as of creating an empathetic society that is based on the value of sharing through more volunteer work and donations. Second, I locate the state programs for marriage immigrants and their multicultural families within its larger efforts to cope with the country's recent demographic changes that are characterized by low fertility and rapid aging. I show that the state's multicultural programs have emerged as part of its governance of the given crisis and of the emergent populations that potentially disrupt existing social integrity, while the multicultural programs that are organized by migrant centers become a self-disciplinary project aimed at the general citizenry. Since its emergence, the problem of foreign migrants has been a good subject to be utilized for the project of moral development led by civil society actors in South Korea. This dissertation explores how this project of engineering the social and ethical dimensions of the subjectivities aimed at the maturation of civil society is increasingly shaped by the neoliberal model of civic responsibility and empathy.

description: A general issue in computational optimization is to develop combinatorial algorithms for semidefinite programming. We address this issue when the base field is nonarchimedean. We provide a solution for a class of semidefinite feasibility problems given by generic matrices. Our approach is based on tropical geometry. It relies on tropical spectrahedra, which are defined as the images by the valuation of nonarchimedean spectrahedra. We establish a correspondence between generic tropical spectrahedra and zero-sum stochastic games with perfect information. The latter have been well studied in algorithmic game theory. This allows us to solve nonarchimedean semidefinite feasibility problems using algorithms for stochastic games. These algorithms are of a combinatorial nature and work for large instances.

Subjects: Biomechanics

description: The purpose of this study was to capture on-field head impact data from the HIT System and xPatch concurrently in order to gain a broader understanding of their ability to appropriately measure head impact biomechanics. Nine collegiate football players participated in this study. We used video analysis to record head impacts during three game sessions. Our findings reveal a moderate correlation between the HIT System and xPatch in measuring linear acceleration and HITsp, and low correlation in measuring rotational acceleration. Our findings also reveal poor agreement in impact location between the recorded impact location of the HIT System and xPatch, and the actual impact location verified by video analysis. Additional analyses revealed the number of false positive head impacts recorded and allowed us to estimate total head impact exposure. Future research should investigate head impact biomechanics in non-helmeted sports and test the xPatch in a laboratory setting.

“Iz nepoznatosti propasti pravo u nepostojanje” [“To plummet from obscurity into nonexistence”]: A study of Aleksandar Tišma’s autobiographical project
Creators: name: Morse, Ainsley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This paper examines the literary oeuvre of the twentieth-century Serbian writer Aleksandar Tišma (1924-2003), focusing particularly on his 1942-1951 diary and the memoir Secaj se veckrat na Vali (2000). Although they were written fifty years apart, these autobiographical works are interconnected and mutually complementary. Tišma’s fictional work also plays an important role in complementing and supplementing the autobiographical information provided in the diary and memoir. Tišma pushes the limits of traditional autobiography in order to create a more nuanced and complete portrait of the writer and his experience. The unusual method and impressive scope of his project is illuminated through an examination of scholarship on autobiography, in particular Philippe Lejeune's concept of "autobiographical space." In connection with this, Tišma's strong ties to literary modernism also help to clarify the processes at work in his unorthodox approach to autobiography.

description: The nature of unconventional superconductivity is intimately linked to the microscopic nature of the pairing interactions. In this work, motivated by cubic heavy fermion compounds with embedded multipolar moments, we theoretically investigate superconducting instabilities instigated by multipolar Kondo interactions. Employing multipolar fluctuations (mediated by RKKY interaction) coupled to conduction electrons via two-channel Kondo and novel multipolar Kondo interactions, we uncover a variety of superconducting states characterized by higher-angular momentum Cooper pairs, $J=0,1,2,3$. We demonstrate that both odd and even parity pairing functions are possible, regardless of the total angular momentum of the Cooper pairs, which can be traced back to the atypical nature of the multipolar Kondo interaction that intertwines conduction electron spin and orbital degrees of freedom. We determine that different (point-group) irrep classified pairing functions may coexist with each other, with some of them characterized by gapped and point node structures in their corresponding quasiparticle spectra. This work lays the foundation for discovery and classification of superconducting states in rare-earth metallic compounds with multipolar local moments.

description: Quantum entanglement represents an ideal resource to guarantee the security of random numbers employed in many scientific and cryptographic applications. However, entanglement-based certified random number generators are particularly challenging to implement. Here, we demonstrate a new certified quantum random number generator based on momentum-polarization entangled single photon states. The use of single photon entanglement allows employing an attenuated laser source and a simple setup where only linear optical components are utilized. For the latter, a semi-device-independent modeling of the photonic quantum random number generator is developed, which certifies a minimum entropy of $(2.5\pm 0.5)\%$, corresponding to a generation rate of 4.4 kHz. At the expenses of a higher level of trust in the system, the certified minimum entropy can be increased to $(30.1 \pm0.5 )\%$, implying a generation rate of 52.7 kHz. Our results show that a simple optical implementation combined with an accurate modeling provide an entanglement-based high-security quantum random number generator using imperfect devices.
Breastfeeding and Contraceptive Use: Analysis of a Statewide Survey

Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Combined estrogen/progestin contraceptive methods have a negative effect on breastfeeding duration when compared to progestin-only methods, non-hormonal methods or using no method. These results suggest that combined hormonal methods should not be recommended to breastfeeding women. This is consistent with current CDC recommendations and strengthens the evidence on which they're founded because this study is recent, US-based, examined current contraceptive options, and controlled for confounding using up-to-date statistical approaches. No effect of progestin-only contraceptive use on breastfeeding duration was found when compared to either non-hormonal methods of birth control or using no method. These results are limited by the lack of information on the timing of initiation of use; in particular, we were not able to distinguish early use, i.e., immediate postpartum, from later use. Consequently, these results should not be interpreted to mean that progestin-only methods are compatible with breastfeeding, but rather that good information about the timing of use will be necessary to clarify the relationship between progestin-only contraceptive use and breastfeeding outcomes. Postpartum contraceptive use by women who initiated breastfeeding was found to be associated with maternal age, maternal educational attainment, race/ethnicity, first birth, infant NICU stay, and the number of breastfeeding-related hospital practices experienced by the mother. Differences in contraception use correspond to breastfeeding rates, suggesting that the issues may be related either with common etiology or by direct effects between them. Pregnancy prevention may outweigh breastfeeding protection in a mother's use of contraception after birth. If so, accurate and available information about the impact of hormonal contraception on breastfeeding is need by these women, as well as having access to reliable and attractive contraceptive methods which are compatible with breastfeeding. Overall, these results highlight the importance of labor and delivery practices that allow and enable immediate breastfeeding initiation for long-term breastfeeding success. These results support the importance of the Ten Steps to Successful Breastfeeding for breastfeeding duration, and suggest that greater adoption of and adherence to this standard could improve breastfeeding outcomes.
Design and Characterization of Chemical Probes Targeting the Chromodomains of Polycomb Repressive Complex I
Creators: name: Stuckey, Jacob
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Eukaryotic DNA is wound around histone proteins to form repeating units of nucleosomes that are packaged into higher order structures to form chromosomes. Nucleosomal packaging is dynamically regulated to control the expression of the genome through regulating access of transcription factors to specific genes in response to stimuli. Critical for these processes are modifications to the N-terminal tails of histones. In particular, methylation of specific histone lysine residues has a profound impact on transcription. This “mark” recruits protein complexes that contain methyl-lysine “reader” modules that bind to the mark and facilitate transcriptional silencing or activation of the underlying gene. Mutation and misregulation of proteins that “write,” “read” and “erase” these marks play a foundational role in the development and progression of nearly all cancers. Chemical tools that antagonize these writers, readers and erasers have been developed in recent years. These tools have been valuable in explicating the biology of these proteins, and in some cases, as therapeutic agents. Development of antagonists of methyl-lysine readers has lagged compared to both methyl-lysine writers and erasers. Herein we describe the design, development and characterization of antagonists of the chromodomain reader modules contained in Polycomb Repressive Complex I (PRC1). PRC1 contains one of five chromodomains; CBX2, -4, -6, -7 or -8. PRC1 complexes containing any one of these proteins play critical roles in normal, growth and development. Accordingly, misregulation of PRC1 chromodomains contributes to the initiation and development of numerous cancers. We developed a series of potent, peptidic antagonists of PRC1 chromodomains and an expanded set of chemical tools around one of these molecules, UNC3866, which has the highest affinity for the chromodomains of CBX4 and -7. We demonstrated the ability of UNC3866 to inhibit proliferation in a metastatic prostate cancer cells through the induction of a senescent-like state. Further optimization of UNC3866 led to a second-generation antagonist of PRC1 chromodomains with a dramatically improved residence time for CBX7 and increased cellular potency. This work has produced a valuable tool set for studying CBX biology and laid the ground work for continued efforts to evaluate and improve CBX antagonists as potential therapeutic agents.

Near-field signal acquisition for smartglasses using two acoustic vector-sensors

description: Smartglasses, in addition to their visual-output capabilities, often contain acoustic sensors for receiving the user's voice. However, operation in noisy environments may lead to significant degradation of the received signal. To address this issue, we propose employing an acoustic sensor array which is mounted on the eyeglasses frames. The signals from the array are processed by an algorithm with the purpose of acquiring the user's desired near-filed speech signal while suppressing noise signals originating from the environment. The array is comprised of two AVSs which are located at the fore of the glasses' temples. Each AVS consists of four collocated subsensors: one pressure sensor (with an omnidirectional response) and three particle-velocity sensors (with dipole responses) oriented in mutually orthogonal directions. The array configuration is designed to boost the input power of the desired signal, and to ensure that the characteristics of the noise at the different channels are sufficiently diverse (lending towards more effective noise suppression). Since changes in the array's position correspond to the desired speaker's movement, the relative source-receiver position remains unchanged; hence, the need to track fluctuations of the steering vector is avoided. Conversely, the spatial statistics of the noise are subject to rapid and abrupt changes due to sudden movement and rotation of the user's head. Consequently, the algorithm must be capable of rapid adaptation. We propose an algorithm which incorporates detection of the desired speech in the time-frequency domain, and employs this information to adaptively update estimates of the noise statistics. Speech detection plays a key role in ensuring the quality of the output signal. We conduct controlled measurements of the array in noisy scenarios. The proposed algorithm preforms favorably with respect to conventional algorithms.

Dimensional enhancements in a quantum battery with imperfections

description: Power storage devices are shown to increase their efficiency if they are designed by using quantum systems. We show that the average power output of a quantum battery based on a quantum interacting spin model, charged via a local magnetic field, can be enhanced with the increase of spin quantum number. In particular, we demonstrate such increment in the power output when the initial state of the battery is prepared as the ground or canonical equilibrium state of the spin-j XY model and the bilinear-biquadratic spin-j Heisenberg chain (BBH) in presence of the transverse magnetic field. Interestingly, we observe that in the case of the XY model, a trade-off relation exists between the range of interactions in which the power increases and the dimension while for the BBH model, the improvements depend on the phase in which the initial state is prepared. Moreover, we exhibit that such dimensional advantages persist even when the battery-Hamiltonian has some defects or when the initial battery-state is prepared at finite temperature.

The value of a pint: a cultural economy of American beer
Creators: name: Beckham, Janel Nikol
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: As a material commodity beer has remained surprisingly unchanged since its discovery--composed of roughly the same ingredients, combined in roughly the same proportions, to achieve roughly the same product. What has been in dramatic flux, particularly over the past 100 years, is how beer is valued. This dissertation considers the numerous and complex ways beer has been and continues to be woven into the fabric of contemporary American life. Changes in the valuation of beer--for instance beer valued as a uniquely taxable and critically profitable source of depression-era internal revenue; as a means of supporting U.S. troops during WWII; as an exemplar of achievable value-added through branding; as a racialized social ill; as a catalyst for technological innovation in packaging and distribution; as emblematic of American masculinity; or as a touchstone of activism advocating sustainable practices of producing, distributing and consuming food and drink--are most often narrowly cast as products of economic change or products of cultural change. In crafting a historically and contextually contingent cultural economy of American beer, this project frames such changes as a complex articulation of the two and in doing so, advances a theory of culturally embedded valuation.

description: Persistent control of a transmon qubit is performed by a feedback protocol based on continuous heterodyne measurement of its fluorescence. By driving the qubit and cavity with microwave signals whose amplitudes depend linearly on the instantaneous values of the quadratures of the measured fluorescence field, we show that it is possible to stabilize permanently the qubit in any targeted state. Using a Josephson mixer as a phase-preserving amplifier, it was possible to reach a total measurement efficiency $η$=35%, leading to a maximum of 59% of excitation and 44% of coherence for the stabilized states. The experiment demonstrates multiple-input multiple-output analog Markovian feedback in the quantum regime.

description: Let $X_k$ denote the number of $k$-term arithmetic progressions in a random subset of $\mathbb{Z}/N\mathbb{Z}$ or $\{1, \dots, N\}$ where every element is included independently with probability $p$. We determine the asymptotics of $\log \mathbb{P}(X_k \ge (1+δ) \mathbb{E} X_k)$ (also known as the large deviation rate) where $p \to 0$ with $p \ge N^{-c_k}$ for some constant $c_k > 0$, which answers a question of Chatterjee and Dembo. The proofs rely on the recent nonlinear large deviation principle of Eldan, which improved on earlier results of Chatterjee and Dembo. Our results complement those of Warnke, who used completely different methods to estimate, for the full range of $p$, the large deviation rate up to a constant factor.
