Plantations--North Carolina
Weddings

description: My thesis project focuses on the preservation of Black cultural historic sites in North Carolina. It will evaluate how Black stories are captured in legacy sites, particularly plantations. It will focus on interviews and gathering relevant literature from scholarly articles, state records of historic sites, financial data and any other applicable documents or information. I propose three articles focusing on the modern use of these spaces, specifically through the lens of plantation weddings.  Each article tackles this subject through a different historic site. Rose Hill Estates is a flourishing, full-functioning wedding venue, with brides of all colors. Once one of the largest plantations in the state by acreage and enslaved population, the private property does not acknowledge this past. Poplar Grove Plantation, a formally white-focused historic property, recently banned on-site weddings in response to the 2020 George Floyd protests. Though struggling financially, they have made the decision to pivot their attention to Black histories in lieu of pursuing greater revenue. Historic Stagville is a fully preserved location and community cultural resource, with hundreds of its slave descendants taking the reins on how the location operates in the modern day. Potential challenges include the sensitive nature of the subject matter and possible hostility from venues that this reporting could negatively affect. My overarching goal is to increase attention and efforts towards the preservation of Black historic sites in North Carolina.

description: Function allocation refers to deciding which tasks should be allocated to humans and which ones to machines. This allocation is important in citizen science projects to operationalize the concept of complementarity and develop systems wherein both humans and machines can benefit from collaboration. Machine learning has been used in several projects to improve classification tasks, such as plants, animals, and galaxies, among others. We present the findings of a descriptive study based on document analysis that aims to examine function allocation between citizen scientists, experts, and machines in 12 citizen science classification projects. We posit this work as a first step towards understanding function allocation and configurations of citizen-in-the-loop. The results indicate that experts are involved in every aspect of the loop, from annotating or labelling data to giving them to algorithms to train and make decisions from such predictions. Experts also test and validate models to improve accuracy by scoring their outputs, when algorithms are not able to make the right decisions. While experts are the humans mainly involved in the loop, citizens are involved as well at various stages of the process. We present two examples of citizens-in-the-loop: when algorithms provide incorrect suggestions and when algorithms are active learners.

What causes geomagnetic activity during sunspot minimum

description: The average geomagnetic activity during sunspot minimum has been continuously decreasing in the last four cycles. The geomagnetic activity is caused by both interplanetary disturbances - coronal mass ejections and high speed solar wind streams, and the background solar wind over which these disturbances ride. We show that the geomagnetic activity in cycle minimum does not depend on the number and parameters of coronal mass ejections or high speed solar wind streams, but on the background solar wind. The background solar wind has two components: slower and faster. The source of the slower component is the heliospheric current sheet, and of the faster one the polar coronal holes. It is supposed that the geomagnetic activity in cycle minimum is determined by the thickness of the heliospheric current sheet which is related to the portions of time the Earth spends in slow and in fast solar wind. We demonstrate that it is also determined by the parameters of these two components of the background solar wind which vary from cycle to cycle.

description: The classical dynamics of collisionless cold dark matter, commonly described by fluid variables or a phase-space distribution, can be captured in a single semiclassical wavefunction. We illustrate how classical multi-streaming creates wave interference in a toy model corresponding to the dynamics of the Zel'dovich approximation and link it to diffraction optics. Wave interference dresses the classical skeleton of cold dark matter with universal features akin to the physical imprints of wavelike (or fuzzy) dark matter. We untangle this wave interference to obtain single-stream wavefunctions corresponding to the classical fluid streams, by writing the wavefunction in an integral form. Our wave decomposition captures the full phase-space information and isolates the multi-stream phenomena related to vorticity and velocity dispersion. We link the wave interference features of our system to the standard forms of diffraction catastrophe integrals, which produce bright caustics in optical fields analogous to the cold dark matter density field. Our two complementary descriptions of dark matter wave-fields present rich universal features that can unlock new ways of modelling and probing wavelike dark matter on the scales of the cosmic web.

description: The contributions of college newspapers to the campuses they serve, the reasons their target audiences value or dismiss them, and the ways changes in the news industry writ large have played out in those journalistic proving grounds are all topics ripe for study. That is particularly true for the student newspapers at small and very small colleges, defined as those with enrollments below 3,000 based on the Carnegie Classification of Institutions of Higher Education (2018). Little research has been done with a focus on the topics outlined at those institutions. This work aims to contribute to filling that void.

description: Reconfigurable intelligent surfaces (RISs) are envisioned as a potentially transformative technology for future wireless communications. However, RISs' inability to process signals and the attendant increased channel dimension have brought new challenges to RIS-assisted systems, including significantly increased pilot overhead required for channel estimation. To address these problems, several prior contributions that enhance the hardware architecture of RISs or develop algorithms to exploit the channels' mathematical properties have been made, where the required pilot overhead is reduced to be proportional to the number of RIS elements. In this paper, we propose a dimension-independent channel state information (CSI) acquisition approach in which the required pilot overhead is independent of the number of RIS elements. Specifically, in contrast to traditional signal transmission methods, where signals from the base station (BS) and the users are transmitted in different time slots, we propose a novel method in which signals are transmitted from the BS and the user simultaneously during CSI acquisition. With this method, an electromagnetic interference random field (IRF) will be induced on the RIS, and we propose the structure of sensing RIS to capture its features. Moreover, we develop three algorithms for parameter estimation in this system, in which one of the proposed vM-EM algorithm is analyzed with the fixed-point perturbation method to obtain an asymptotic achievable bound. In addition, we also derive the Cramér-Rao lower bound (CRLB) and an asymptotic expression for characterizing the best possible performance of the proposed algorithms. Simulation results verify that our proposed signal transmission method and the corresponding algorithms can achieve dimension-independent CSI acquisition for beamforming.
description: Accepted by IEEE Transactions on Information Theory. To address the high pilot overhead in RIS-assisted systems, this paper exploits the physical phenomenon of electromagnetic interference to reduce the pilot overhead to a constant number independent of the RIS's size.

description: We consider a family of translation-invariant quantum spin chains with nearest-neighbor interactions and derive necessary and sufficient conditions for these systems to be gapped in the thermodynamic limit. More precisely, let $ψ$ be an arbitrary two-qubit state. We consider a chain of $n$ qubits with open boundary conditions and Hamiltonian $H_n(ψ)$ which is defined as the sum of rank-1 projectors onto $ψ$ applied to consecutive pairs of qubits. We show that the spectral gap of $H_n(ψ)$ is upper bounded by $1/(n-1)$ if the eigenvalues of a certain two-by-two matrix simply related to $ψ$ have equal non-zero absolute value. Otherwise, the spectral gap is lower bounded by a positive constant independent of $n$ (depending only on $ψ$). A key ingredient in the proof is a new operator inequality for the ground space projector which expresses a monotonicity under the partial trace. This monotonicity property appears to be very general and might be interesting in its own right. As an extension of our main result, we obtain a complete classification of gapped and gapless phases of frustration-free translation-invariant spin-1/2 chains with nearest-neighbor interactions.

description: Согласно 172-ФЗ «О стратегическом планировании в Российской Федерации» с 2014 года все муниципальные образования, и прежде всего крупнейшие города, осуществляют стратегическое планирование и разрабатывают муниципальные программы. С 2016 года помимо программ органы местного самоуправления должны организовать проектную деятельность. Таким образом, на уровне крупнейших городов формируется программно-проектный механизм, который направлен на их стратегическое развитие. На сегодняшний день нет единого методического подхода к определению данного механизма и его подсистем, не определена его взаимосвязь со стратегией развития крупнейших городов. В данной статье очерчивается сфера программно-проектного механизма в системе управления городом: концентрация ресурсов на выполнении задач функционирования города и на реализации проектов, обеспечивающих прорывные решения проблем социально-экономического развития города. В статье конкретизированы процессы программно-проектного механизма, определены его основные подсистемы: объектная, функциональная и обеспечивающая.According to 172 Federal Law «About the Strategic Planning in the Russian Federation», since 2014 all municipalities, and especially the largest cities, carry out strategic planning and develop municipal programs. Since 2016, in addition to programs, local governments should organize project activities. Thus, at the level of the largest cities, a program and project mechanism is being formed and focused at cities’ strategic development. Currently, there is no single methodological approach to the definition of this mechanism and its subsystems, its relationship with the development strategy of the largest city has not been determined. This article outlines the scope of the program and project mechanism in the city management system: the concentration of resources on tasks focused on city functioning and implementation of projects that provide breakthrough solutions to the problems of city’s socio-economic development. The article specifies the processes of program and project mechanism, defines its main subsystems: object, functional and supporting.

description: The consensus is that an object with a large mass will not manifest quantum behavior. Therefore, we expect that the quantumness of a time-dependent effective mass (TDEM) will erase after a long time when the mass profile continuously grows with time. However, the present article depicts that the Wigner quasi-probability distribution (WQD) will manifest an entanglement behavour forever for two spatially separated free TDEM. The time-dependent Schrödinger equation for a free particle with TDEM is solved with the help of Lewis-Riesenfeld phase space invariant method. WQD for the system of two identical TDEM with quadratically increasing mass profile shows that the particles are never separated. In particular, their reminiscent is present at the origin of the phase-space forever.

description: Transfer students represent a significant opportunity for UNC Asheville. Efforts to recruit community college students to four-year institutions, however, requires a deep understanding of the motivations for and barriers to pursuing a bachelor’s degree. Through in-depth interviews, this thesis project uncovered the perspectives of both UNC Asheville’s current transfer students and prospective transfer students from local community colleges—specifically, their educational goals, professional goals, college search and decision-making processes, and their level of satisfaction with their educational experiences thus far. Several central themes emerged to reveal common characteristics, perspectives, and experiences among transfer students. The paths that transfer students take to earn their bachelor’s degrees vary and are largely influenced by external factors. Students enroll in community college as an affordable way to explore fields of interest and careers, with the goal of transferring to a four-year institution to complete their bachelor’s degrees. While they are career-driven, self-fulfillment is also a professional priority for them. They encounter unique challenges along their educational journeys, balance many obligations outside of their coursework, and need specific support to ensure a smooth transition and acclimation from community college to their four-year institution. Findings informed the development of a best practices manual to help undergraduate admissions and marketing professionals better understand this underserved, but significant, student population.

description: North Carolina’s Division of Marine Fisheries (DMF) is one of several divisions within the North Carolina Department of Environmental Quality that protects the state’s marine and estuarine resources. Protections occur through a variety of means that address habitat, fisheries management, shellfish sanitation, and recreational water quality.  As part of fisheries management, the NCDMF acquired a series of permits under federal law, such as the Section 10 Incidental Take Permits (ITPs) from the NOAA Fisheries (NMFS) under Section 10(a)(1)(B) of the Endangered Species Act (ESA) of 1973 (Public Law 93-205). As part of the permits’ conservations plan the DMF is required to maintain a certain percentage of estuarine gill-net trips to be observed by the DMF’s Observer Program to monitor levels of incidental takes of several endangered species and implement mitigation measures if needed based on tose levels. The purpose of this project is to analyze the communication between North Carolina commercial fishermen and observers with the Observer Program. Nine in-depth interviews were conducted with Observer Program affiliates, North Carolina Marine Patrol officers, and commercial gill-net fishers. Five observations were conducted to see firsthand the interaction between the fishers and the observers. Findings suggested that the fisher’s lack of willing participation in the program is due to an absence of understanding the program in a variety of ways. A communication plan was created to combat this and to improve interrelations with fishers and the program.

description: Exotic objects such as the Ellis wormhole are expected to act as gravitational lenses. Much like their nonexotic counterparts, information about these lenses can be found by considering the strong and weak lensing fields they induce. In this work, we consider how weak gravitational lensing flexion can provide information beyond that of shear. We find that directional flexion can distinguish between the case of a positive or negative convergence where directional shear cannot, and therefore can provide a unique lensing signature for objects with an Ellis wormhole-type metric. We also consider cosmic flexion, the flexion correlation function whose signal originates from the large-scale structure of the Universe, in the context of modified gravity. We find flexion to be a unique probe of parametric models of modified gravity, particularly in the case of scale-dependent phenomenological post-general relativity functions.

description: We provide experimental and numerical evidence for thermal excitations within and among magnetic mesospins, forming artificial spin ice structures. At low temperatures, a decrease in magnetization and increase in susceptibility is observed with increasing temperature, interpreted as an onset of thermal fluctuations of the magnetic texture within the mesospins. At elevated temperatures a pronounced susceptibility peak is observed, related to thermally induced flipping of the mesospins and a collapse of the remanent state. The fluctuations, while occurring at distinct length- and energy-scales, are shown to be tunable by the interaction strength of the mesospins.

description: We present calculations of the correlation energies of crystalline solids and isolated systems within the adiabatic-connection fluctuation-dissipation formulation of density-functional theory. We perform a quantitative comparison of a set of model exchange-correlation kernels originally derived for the homogeneous electron gas (HEG), including the recently-introduced renormalized adiabatic local-density approximation (rALDA) and also kernels which (a) satisfy known exact limits of the HEG, (b) carry a frequency dependence or (c) display a 1/$k^2$ divergence for small wavevectors. After generalizing the kernels to inhomogeneous systems through a reciprocal-space averaging procedure, we calculate the lattice constants and bulk moduli of a test set of 10 solids consisting of tetrahedrally-bonded semiconductors (C, Si, SiC), ionic compounds (MgO, LiCl, LiF) and metals (Al, Na, Cu, Pd). We also consider the atomization energy of the H$_2$ molecule. We compare the results calculated with different kernels to those obtained from the random-phase approximation (RPA) and to experimental measurements. We demonstrate that the model kernels correct the RPA's tendency to overestimate the magnitude of the correlation energy whilst maintaining a high-accuracy description of structural properties.

description: Binding of two heavy fermions interacting with a light particle via the contact interaction is possible only for sufficiently large heavy-light mass ratio. In this work, the two-variable inequality is derived to determine a specific value $ μ^* $ providing that there are no three-body bound states for the mass ratio smaller than $ μ^* $. The value $ μ^* = 5.26 $ is obtained by analyzing this inequality for a total angular momentum and parity $ L^P = 1^- $. For other $ L^P $ sectors, the specific mass-ratio values providing an absence of the three-body bound states are found in a similar way. For generality, the method is extended to determine corresponding mass-ratio values for the system consisting of two identical bosons and a distinct particle for different $ L^P $ ($ L > 0 $) sectors.

description: Recent measurements of microwave and X-ray emission during edge localised mode (ELM) activity in tokamak plasmas provide a fresh perspective on ELM physics. It is evident that electron kinetics, which are not incorporated in standard (fluid) models for the instability that drives ELMs, play a key role in the new observations. These effects should be included in future models for ELMs and the ELM cycle. The observed radiative effects paradoxically imply acceleration of electrons parallel to the magnetic field combined with rapid acquisition of perpendicular momentum. It is shown that this paradox can be resolved by the action of the anomalous Doppler instability which enables fast collective radiative relaxation, in the perpendicular direction, of electrons accelerated in the parallel direction by inductive electric fields generated by the initial ELM instability.

description: Extremely large angular orbital momentum can be produced in non-central heavy-ion collisions, leading to a strong transverse polarization of partons that scatter through the quark-gluon plasma (QGP) due to spin-orbital coupling. We develop a perturbative approach to describe the formation and spacetime evolution of quark polarization inside the QGP. Polarization from both the initial hard scatterings and interactions with the QGP have been consistently described using the quark-potential scattering approach, which has been coupled to realistic initial condition calculation and the subsequent (3+1)-dimensional viscous hydrodynamic simulation of the QGP for the first time. Within this improved approach, we have found that different spacetime-rapidity-dependent initial energy density distributions generate different time evolution profiles of the longitudinal flow velocity gradient of the QGP, which further lead to an approximately 15% difference in the final polarization of quarks collected on the hadronization hypersurface of the QGP. Therefore, in addition to the collective flow coefficients, the hyperon polarization may serve as a novel tool to help constrain the initial condition of the hot nuclear matter created in high-energy nuclear collisions.

description: Generalizing Reiner's notion of set partitions of type $B_n$, we define colored $B_n$-partitions by coloring the elements in and not in the zero-block respectively. Considering the generating function of colored $B_n$-partitions, we get the exact formulas for the expectation and variance of the number of non-zero-blocks in a random colored $B_n$-partition. We find an asymptotic expression of the total number of colored $B_n$-partitions up to an error of $O(n^{-1/2}\log^{7/2}{n})$, and prove that the centralized and normalized number of non-zero-blocks is asymptotic normal over colored $B_n$-partitions.

When Pragmatism Prompts Recentralization: EU Accession and Executive Constraints in the Czech Republic and Hungary

description: The Gates et. al. (2010) model of government transformation predicts that the most stable polities are either fully democratic or autocratic. This stability derives from the confluence of executive recruitment, executive constraints, and participation. Applying this model to the 'big bang' era of EU enlargement, the Czech Republic and Hungary can be viewed as having undergone a process of democratization buttressed by the exogenous hand of the EU. Why, then, did both of these countries backslide into more illiberal governing policies in the 2010s, years after their 2004 accessions? One potential way in which these countries may have inadvertently developed institutional frameworks vulnerable to an insufficiently constrained executive was through the Agenda 2000 funding rules applied to regional development programs in the pre-accession era, beginning in 1998. This thesis explores the ways in which these rules were applied in the then-candidate countries, and the recentralization of the central executive apparatuses that resulted.

description: We study quantum thermalization and thermal entanglement in the open quantum Rabi model (QRM), in which a two-level system and a single-mode bosonic field are coupled to either two individual heat baths or a common heat bath. By treating the QRM as an effective multilevel system and deriving global quantum master equations in the eigenstate representation of the QRM, we study the physical conditions for quantum thermalization of the open QRM. It is found that, in the individual heat-bath case, the QRM can only be thermalized when either the two heat baths have the same temperature or the QRM is only coupled to one of the two baths. In the common heat-bath case, differently, the QRM can always be thermalized. We also study thermal entanglement of the QRM in both the resonant- and non-resonant coupling cases. The logarithmic negativity for the thermal state of the QRM is obtained in a wide parameter space, ranging from the low- to high-temperature limits, and from the weak- to deep-strong-coupling regimes. This work paves the way towards the study of quantum effects in nonequilibrium ultrastrongly-coupled light-matter systems.

description: This paper studies inference acceleration using distributed convolutional neural networks (CNNs) in collaborative edge computing. To ensure inference accuracy in inference task partitioning, we consider the receptive-field when performing segment-based partitioning. To maximize the parallelization between the communication and computing processes, thereby minimizing the total inference time of an inference task, we design a novel task collaboration scheme in which the overlapping zone of the sub-tasks on secondary edge servers (ESs) is executed on the host ES, named as HALP. We further extend HALP to the scenario of multiple tasks. Experimental results show that HALP can accelerate CNN inference in VGG-16 by 1.7-2.0x for a single task and 1.7-1.8x for 4 tasks per batch on GTX 1080TI and JETSON AGX Xavier, which outperforms the state-of-the-art work MoDNN. Moreover, we evaluate the service reliability under time-variant channel, which shows that HALP is an effective solution to ensure high service reliability with strict service deadline.

description: This document describes the package CHIRON which includes two libraries, chiron itself and jbnumlib. CHIRON is a set of routines useful for two-loop numerical results in Chiral Perturbation Theory (ChPT). It includes programs for the needed one- and two-loop integrals as well as routines to deal with the ChPT parameters. The present version includes everything needed for the masses, decay constants and quark-antiquark vacuum-expectation-values. An added routine calculates consistent values for the masses and decay constants when the pion and kaon masses are varied. In addition a number of finite volume results are included: one-loop tadpole integrals, two-loop sunset integrals and the results for masses and decay constants. The numerical routine library jbnumlib contains the numerical routines used in chiron. Many are to a large extent simple C++ versions of routines in the CERNLIB numerical library. Notable exceptions are the dilogarithm and the Jacobi theta function implementations. This paper describes what is included in CHIRON v0.50.

Examining the Role and Value of Battery Storage in North Carolina: Meeting IPCC Emissions Targets Under Increasing Penetration Levels of  Solar and Wind Generation Technologies in the Power Grid
Creators: name: Snyder, Austin

description: In North Carolina, the primary electricity generation options to achieve a decarbonized electric grid are solar and wind electricity. In recent years, battery storage has become a clear contender to serve as a major support mechanism for these variable generation technologies in electric grids around the world. To explore the potential of battery storage in decarbonizing North Carolina’s electric grid, this paper quantifies the air pollution impacts and social costs integrating battery storage with varying penetration levels of intermittent solar and wind technologies in North Carolina. By applying a screening curve approach to predict the future of the North Carolina electric grid, this paper utilizes historical load profiles and modeled wind and solar outputs to project future integration of variable renewable electricity in North Carolina. Through a daily charging algorithm for battery storage, this paper models system-level emissions impacts and grid costs at high penetrations of wind and solar deployment. To investigate how a high-penetration renewable future for North Carolina will impact the operations of existing power plants, the model examines how different levels of storage deployment effects emissions. These deployment strategies are compared across various IPCC target scenarios to understand how higher penetrations of solar and wind would impact the emissions reduction benefits of energy storage. Impacts are compared across standards of total net demand, levelized cost of electricity per kilowatt-hour, and greenhouse gas (GHG) emissions. Additionally, this paper estimates the social value of storage as a method of reducing the social costs associated with greenhouse gas emissions in tandem with variable technologies.
