description: This document is a letter report that serves as an Archaeological Impact Statement for the proposed construction of an antenna base immediately adjacent to Building 23251 at its western edge. According to information provided by the Federal Electric Corporation, sponsors for the construction, the proposed effort would involve emplacing a five foot square concrete pad to a depth of one foot at this location. No additional disturbance of the surface would result. Construction is located near CA-SBA-793, but no archaeological materials were recovered in the survey.

description: We investigated the magnetic properties of polycrystalline samples of the intrinsic magnetic topological insulators MnPn2Te4, with pnictogen Pn = Sb, Bi, by bulk magnetization and μSR. DC susceptibility detects the onset of magnetic ordering at TN = 27 K and 24 K and a field dependence of the macroscopic magnetization compatible with ferri- (or ferro-) and atiferro- magnetic ordering, respectively. Weak transverse field (wTF) Muon Spin Rotation (μSR) confirms the homogeneous bulk nature of magnetic ordering at the same two distinct transition temperatures. Zero Field (ZF) μSR shows that the Sb based material displays a broader distribution of internal field at the muon, in accordance with a larger deviation from the stoichiomectric composition and a higher degree of positional disorder (Mn at the Pn(6c) site), which however does not affect significantly the sharpness of the thermodynamic transition, as detected by the muon magnetic volume fraction and the observability of a critical divergence in the longitudinal and transverse muon relaxation rates.

description: Lors de la transition des études secondaires aux études universitaires, les étudiants et les étudiantes sont confrontés à un processus d’adaptation psychosocial. Ce processus peut être facilité ou entravé par le soutien social des pairs, du corps professoral, du personnel administratif et de la vie sur le campus. Alors que, dans le contexte de confinement imposé par la pandémie de la COVID- 19, ce soutien social s’est vécu, à tout le moins, en virtuel. De cette situation exceptionnelle émerge une question fort importante. Comment les étudiants et les étudiantes inscrit-e-s en première année universitaire ont vécu ce processus d’adaptation psychosocial à leur nouvel état de vie ? Cette question constitue notre objectif de recherche. Objectif qui vise à décrire l’expérience d’adaptation psychosociale de ces étudiants et étudiantes. L’analyse qualitative des données conduite auprès d’un participant et deux participantes a mis en lumière le fait que l’absence de soutien social en présentiel a lourdement compliqué le processus d'adaptation psychosocial. Toutefois, le participant et les participantes ont développé des stratégies d’adaptation qui leur a permis de poursuivre leurs études. Plus spécifiquement, l’analyse qualitative des données a mis en évidence que la présence d’un projet vocationnel ou de carrière a permis de suppléer, du moins en partie, à la carence d’un soutien social.

description: We study the qualitative properties of optimal regularisation parameters in variational models for image restoration. The parameters are solutions of bilevel optimisation problems with the image restoration problem as constraint. A general type of regulariser is considered, which encompasses total variation (TV), total generalized variation (TGV) and infimal-convolution total variation (ICTV). We prove that under certain conditions on the given data optimal parameters derived by bilevel optimisation problems exist. A crucial point in the existence proof turns out to be the boundedness of the optimal parameters away from $0$ which we prove in this paper. The analysis is done on the original -- in image restoration typically non-smooth variational problem -- as well as on a smoothed approximation set in Hilbert space which is the one considered in numerical computations. For the smoothed bilevel problem we also prove that it $Γ$ converges to the original problem as the smoothing vanishes. All analysis is done in function spaces rather than on the discretised learning problem.

description: We present the first observations of extragalactic pulsating stars in the K2 ecliptic survey of the Kepler space telescope. Variability of all three RR Lyrae stars in the dwarf spheroidal galaxy Leo IV were successfully detected, at a brightness of Kp~21.5 mag, from data collected during Campaign 1. We identified one modulated star and another likely Blazhko candidate with periods of 29.8+-0.9 d and more than 80 d, respectively. EPIC 210282473 represents the first star beyond the Magellanic Clouds for which the Blazhko period and cycle-to-cycle variations in the modulation were unambiguously measured.The photometric [Fe/H] indices of the stars agree with earlier results that Leo IV is a very metal-poor galaxy. Two out of three stars blend with brighter background galaxies in the K2 frames. We demonstrate that image subtraction can be reliably used to extract photometry from faint confused sources that will be crucial not only for the K2 mission but for future space photometric missions as well.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: An increasing number of people use social media to find and share health information; this study sought to explore this information’s quality by focusing on health information distributed on online peer-to-peer infertility discussion forums. This study asked the following question: What is the quality of infertility health information posted to peer online-infertility discussion forums, as rated by health sciences librarians? Specifically,
this research seeks to expand on an earlier study that suggests quality health information can be found on online forums. Health librarians were given a sample of infertility forum threads from infertility forums and asked to evaluate the accuracy of the information on a five-question scale. Some of this study’s results suggest health forums might be a useful information tool as part of a larger clinical treatment plan guided by a doctor. However, other scales of measurement in this study suggest the results are inconclusive.

description: Given a planar graph $G$ and a partition of the neighbors of each vertex $v$ in four sets $UR(v)$, $UL(v)$, $DL(v)$, and $DR(v)$, the problem Windrose Planarity asks to decide whether $G$ admits a windrose-planar drawing, that is, a planar drawing in which (i) each neighbor $u \in UR(v)$ is above and to the right of $v$, (ii) each neighbor $u \in UL(v)$ is above and to the left of $v$, (iii) each neighbor $u \in DL(v)$ is below and to the left of $v$, (iv) each neighbor $u \in DR(v)$ is below and to the right of $v$, and (v) edges are represented by curves that are monotone with respect to each axis. By exploiting both the horizontal and the vertical relationship among vertices, windrose-planar drawings allow to simultaneously visualize two partial orders defined by means of the edges of the graph. Although the problem is NP-hard in the general case, we give a polynomial-time algorithm for testing whether there exists a windrose-planar drawing that respects a given combinatorial embedding. This algorithm is based on a characterization of the plane triangulations admitting a windrose-planar drawing. Furthermore, for any embedded graph with $n$ vertices that has a windrose-planar drawing, we can construct one with at most one bend per edge and with at most $2n-5$ bends in total, which lies on the $3n \times 3n$ grid. The latter result contrasts with the fact that straight-line windrose-planar drawings may require exponential area.

description: The evolution of many kinetic processes in 1+1 (space-time) dimensions results in 2d directed percolative landscapes. The active phases of these models possess numerous hidden geometric orders characterized by various types of large-scale and/or coarse-grained percolative backbones that we define. For the patterns originated in the classical directed percolation (DP) and contact process (CP) we show from the Monte-Carlo simulation data that these percolative backbones emerge at specific critical points as a result of continuous phase transitions. These geometric transitions belong to the DP universality class and their nonlocal order parameters are the capacities of corresponding backbones. The multitude of conceivable percolative backbones implies the existence of infinite cascades of such geometric transitions in the kinetic processes considered. We present simple arguments to support the conjecture that such cascades of transitions is a generic feature of percolation as well as many others transitions with nonlocal order parameters.

Dispatches from the 200's: A case study in religious representation in the Wake County Public Library System
Creators: name: Helms, Alexandra

Year: 2020

description: Nonfiction sections in public libraries are an important resource for patrons in an age of misinformation and disinformation. It is imperative that these sections offer diverse points of view to promote equity and community, especially among people of different faiths. Collections may unwittingly promote one view or faith over others. This is counter to the library’s mission of equity and access. This study addresses questions about the adult and juvenile religious nonfiction collections in the Wake County Public Library System, with particular regard to representation of faiths outside of Mainstream Christian faiths. This study uses quantitative content analysis to assess the representativeness of the collections.

EXPLORING ADOLESCENT AND YOUNG ADULT CANCER SURVIVORS’ MOTIVATIONS FOR PHYSICAL ACTIVITY BEHAVIORS AND ENROLLMENT IN PHYSICAL ACTIVITY INTERVENTIONS
Creators: name: Chisholm, Miriam
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Though a growing field, adolescent and young adult (AYA) cancer survivorship research has several knowledge gaps. For instance, many scientists report challenges recruiting AYAs cancer survivors to intervention research, and little is known regarding what motivates AYAs who do participate in studies. Using data from the THRIVE intervention study, this study analyzed the associations between AYA cancer survivors’ sociodemographic characteristics and motivations for joining a mobile physical activity (PA) intervention as well as the associations between these motivations and PA attainment in the study. Results of a series of chi-square analyses revealed associations between education and PA-related motivations, income and PA-related motivations, stage at diagnosis and research interest motivation, insurance and research interest motivation, and income and research interest motivation. Further, results of ANOVA analyses do not support an association between motivations for joining a mobile PA intervention and PA outcomes in the study. Consistent with prior research, over 60% of participants in this study endorsed PA-related, weight-related, and research interest motivations for joining the study. Study findings provide insight into ways to improve recruitment strategies to engage AYA cancer survivors in future PA interventions.

description: Many unusual and promising properties have been reported recently for the transition metal trichalcogenides of the type MPS3 (M = V, Mn, Fe, Ni..), such as maintaining magnetic order to the atomically thin limit, ultra-sharp many-body excitons, metal-insulator transitions and, especially for Fe2P2S6, giant linear dichroism among others. Here we conduct a detailed investigation of the electronic structure of Fe2P2S6 using angle-resolved photoemission spectroscopy, q-dependent electron energy loss spectroscopy, optical spectroscopies and density functional theory. Fe2P2S6 is a Mott insulator with a gap of E gap ≈ 1.4 eV and zigzag antiferromagnetism below T N = 119 K. The low energy excitations are dominated by Fe 3d states. Large and sign-changing linear dichroism is observed. We provide a microscopic mechanism explaining key properties of the linear dichroism based on the correlated character of the electronic structure, thereby elucidating the nature of the spin-charge coupling in Fe2P2S6 and related materials.

description: The field of two dimensional (2D) materials experienced a surge of discoveries after the isolation of graphene. Among these, the transition metal compounds of Molybdenum and tungsten have been the most extensively studied materials after graphene. More recently, their group member chromium has only recently come to the limelight after the discovery of its exciting magnetic properties. As such the body of work surrounding 2D chromium-based materials is growing. Here, we present an up-to-date summary of the chromium 2D materials showing the latest advances in their experimental synthesis, characterization and the applications of 2D Chromium-based compounds. Finally, we conclude with a perspective on the future of 2D chromium-based materials. We believe that this study will be helpful to understand the field of chromium-based 2D compounds.
Mobile AR Telepresence

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: With the advancement of AR/VR technologies, there has been much research on 3D telepresence over the past few years. Here, we propose an approach for AR mobile 3D telepresence that uses only AR headsets and a few inertial sensors worn by a user. This egocentric approach that we adopted allows 3D human body reconstruction anywhere with fewer constraints and more convenience than previous approaches that rely on external cameras. Our expanded egocentric system has two major innovations: 1) it utilizes Inertial Measurement Units (IMUs) to track user movements not always seen by the headset cameras, such as legs and arms, and 2) it improves the reconstruction of the user's body by utilizing cameras worn by a nearby collaborator if present. Our system employs a template-based method for human body reconstruction. The reconstruction starts with a parametric Skinned Multi-Person Linear (SMPL) human body model, and changes the parameters of the model over time. For each time interval during the capture, our system predicts poses and retargets them back to the human body model. Our system also progressively updates the model with shapes and textures that have higher fidelity, derived from the collaborative user's camera images.

This thesis introduces the structure of the system and elaborates on the parts of the system where I have contributed the most: 1)integration of reconstruction data such as texture, shape and pose of the human body, 2) use of the SMPL human body model and 3) design of a prototypical demonstration.

description: Fluorescence photoacoustic tomography (fPAT) is a molecular imaging modality that combines photoacoustic tomography (PAT) with fluorescence imaging to obtain high-resolution imaging of fluorescence distributions inside heterogeneous media. The objective of this work is to study inverse problems in the quantitative step of fPAT where we intend to reconstruct physical coefficients in a coupled system of radiative transport equations using internal data recovered from ultrasound measurements. We derive uniqueness and stability results on the inverse problems and develop some efficient algorithms for image reconstructions. Numerical simulations based on synthetic data are presented to validate the theoretical analysis. The results we present here complement these in [Ren-Zhao, SIAM J. Imag. Sci., 2013] on the same problem but in the diffusive regime.

description: The properties of a balanced two-component Fermi gas in a one-dimensional harmonic trap are studied by means of the coupled cluster method. For few fermions we recover the results of exact diagonalization, yet with this method we are able to study much larger systems. We compute the energy, the chemical potential, the pairing gap, and the density profile of the trapped clouds, smoothly mapping the crossover between the few-body and many-body limits. The energy is found to converge surprisingly rapidly to the many-body result for every value of the interaction strength. Many more particles are instead needed to give rise to the non-analytic behavior of the pairing gap, and to smoothen the pronounced even-odd oscillations of the chemical potential induced by the shell structure of the trap.

description: Inducing a magnetic gap at the Dirac point of the topological surface state (TSS) in a three-dimensional (3D) topological insulator (TI) is a route to dissipationless charge and spin currents. Ideally, magnetic order is present only at the surface, as through proximity of a ferromagnetic (FM) layer. However, experimental evidence of such a proximity-induced Dirac mass gap is missing, likely due to an insufficient overlap of TSS and the FM subsystem. Here, we take a different approach, namely ferromagnetic extension (FME), using a thin film of the 3D TI Bi2Te3, interfaced with a monolayer of the lattice-matched van der Waals ferromagnet MnBi2Te4. Robust 2D ferromagnetism with out-of-plane anisotropy and a critical temperature of Tc≈15 K is demonstrated by x-ray magnetic dichroism and electrical transport measurements. Using angle-resolved photoelectron spectroscopy, we observe the opening of a sizable magnetic gap in the 2D FM phase, while the surface remains gapless in the paramagnetic phase above Tc. Ferromagnetic extension paves the way to explore the interplay of strictly 2D magnetism and topological surface states, providing perspectives for realizing robust quantum anomalous Hall and chiral Majorana states.

description: We propose an extension of non-parametric multivariate finite mixture models by dropping the standard conditional independence assumption and incorporating the independent component analysis (ICA) structure instead. We formulate an objective function in terms of penalized smoothed Kullback Leibler distance and introduce the nonlinear smoothed majorization-minimization independent component analysis (NSMM-ICA) algorithm for optimizing this function and estimating the model parameters. We have implemented a practical version of this algorithm, which utilizes the FastICA algorithm, in the R package icamix. We illustrate this new methodology using several applications in unsupervised learning and image processing.

description: Understanding the martensitic microstructure in nickel-titanium (NiTi) thin films helps to optimize their properties for applications in microsystems. Epitaxial and single-crystalline films can serve as model systems to understand the microstructure, as well as to exploit the anisotropic mechanical properties of NiTi. Here, we analyze the growth of NiTi on single-crystalline MgO(100) and Al2O3(0001) substrates and optimize film and buffer deposition conditions to achieve epitaxial films in (100)- and (111)-orientation. On MgO(100), we compare the transformation behavior and crystal quality of (100)-oriented NiTi films on different buffer layers. We demonstrate that a vanadium buffer layer helps to decrease the low-angle grain boundary density in the NiTi film, which inhibits undesired growth twins and leads to higher transformation temperatures. On Al2O3(0001), we analyze the orientation of a chromium buffer layer and find that it grows (111)-oriented only in a narrow temperature range around 500 ∘C. By depositing the Cr buffer below the NiTi film, we can prepare (111)-oriented, epitaxial films with transformation temperatures above room temperature. Transmission electron microscopy confirms a martensitic microstructure with Guinier Preston-zone precipitates at room temperature. We identify the deposition conditions to approach the ideal single crystalline state, which is beneficial for the analysis of the martensitic microstructure and anisotropic mechanical properties in different film orientations.

description: We realize on an Atom-Chip a practical, experimentally undemanding, tomographic reconstruction algorithm relying on the time-resolved measurements of the atomic population distribution among atomic internal states. More specifically, we estimate both the state density matrix as well as the dephasing noise present in our system by assuming complete knowledge of the Hamiltonian evolution. The proposed scheme is based on routinely performed measurements and established experimental procedures, hence providing a simplified methodology for quantum technological applications.

description: Many current popular devices such as Fitbit and Apple Watch  continuously monitor movement and activity, but they are primarily marketed towards individuals aiming for fitness improvements, and not those with chronic medical conditions. For people with chronic conditions, or elderly individuals, having to use a wearable can  be obstructive and annoying. Furthermore, when trying to study patient motion or behavior, the use of the wearable can impact their actions due to the burden of having to wear the device. Thus, there is a need for a contactless medical device that does not apply this burden to its users. Given this, there is a related need to ensure appropriate validation and preprocessing of data collected from these devices. Using data from the Emerald Device of the Katabi Lab at MIT, this thesis aims to work on the issue of validation and preprocessing of this data.

description: Starting with geometrical premises, we infer the existence of fundamental cosmological scalar fields. We then consider physically relevant situations in which spacetime metric is induced by one or, in general, by two scalar fields, in accord with the Papapetrou algorithm. The first of these fields, identified with dark energy, has exceedingly small but finite (subquantum) Hubble mass scale (~ 10^-33 eV), and might be represented as a neutral superposition of quasi-static electric fields. The second field is identified with dark matter as an effectively scalar conglomerate composed of primordial neutrinos and antineutrinos in a special tachyonic state.

The Impact of Nurse Residency Programs on New Graduate Nurse Retention and Satisfaction
Creators: name: Clapp, Jamesanna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Background: With nearly 27.1% of new graduate nurses leaving the position, the need to attract and retain new grads in healthcare is crucial. The transition period between graduation and clinical practice can be demanding, overwhelming, and highly stressful leading to a decrease in overall work satisfaction. The incorporation of nurse residency programs (NRPs) is one way to ease the critical transition period. NRPs are offered for new graduate nurses in the first year of hire, but often lack consistency in both program structure and program outcomes. 
Purpose: The purpose of this integrative review of literature is to examine: For new graduate nurses with their first year of hire, does the use of a structured NRP increase nurse retention and satisfaction? 
Methods: A systematic review of the literature was performed using the key terms related to new graduate nurse, nurse residency programs, and outcome variables of nurse retention and satisfaction. Databases searched included CINAHL, PubMed, Ovid, and grey literature within the past five years, 2014-2019. 
Results: Organizations with NRPs, regardless of structure, showed a consistent increase in both new graduate nurse retention and work satisfaction. Recent innovations strategies such as specialized programs and multidisciplinary simulations, were identified highlighting the evolving nature and relevance of nurse residency programs.

description: We show that the two additional Lagrangians that appear in theories beyond Horndeski can be reexpressed in terms of simple generalizations of the "John" and "Paul" terms of the Fab Four theories. We find that these extended Fab Four satisfy the same properties of self-tuning as the original Fab Four.

description: Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets. This tends to mask the physics of the relativistic quasiparticles. Using the example of ZrTe5, we show that strain provides a powerful tool for in-situ tuning of the band structure such that all trivial pockets are pushed far away from the Fermi energy, but only for a certain range of Van der Waals gaps. Our results naturally reconcile contradicting reports on the presence or absence of additional pockets in ZrTe5, and provide a clear map of where to find a pure three-dimensional Dirac semimetallic phase in the structural parameter space of the material.

description: Investigations into using visualization to improve Bayesian reasoning and advance risk communication have produced mixed results, suggesting that cognitive ability might affect how users perform with different presentation formats. Our work examines the cognitive load elicited when solving Bayesian problems using icon arrays, text, and a juxtaposition of text and icon arrays. We used a three-pronged approach to capture a nuanced picture of cognitive demand and measure differences in working memory capacity, performance under divided attention using a dual-task paradigm, and subjective ratings of self-reported effort. We found that individuals with low working memory capacity made fewer errors and experienced less subjective workload when the problem contained an icon array compared to text alone, showing that visualization improves accuracy while exerting less cognitive demand. We believe these findings can considerably impact accessible risk communication, especially for individuals with low working memory capacity.
Modelling the artificial night sky brightness at short distances from streetlights

description: Contrary to some widespread intuitive belief, the night sky brightness perceived by the human eye or any other physical detector does not come (exclusively) from high in the sky. The detected brightness is built up from the scattered radiance contributed by all elementary atmospheric volumes along the line of sight, starting from the very first millimeter from the eye cornea or the entrance aperture of the measuring instrument. In artificially lit environments, nearby light sources may be responsible for a large share of the total perceived sky radiance. We present in this paper a quantitative analytical model for the sky radiance in the vicinity of outdoor light sources, free from singularities at the origin, which provides useful insights for the correct design or urban dark sky places. It is found that the artificial zenith sky brightness produced by a small ground-level source detected by a ground-level observer at short distances (from the typical dimension of the source up to several hundred meters) decays with the inverse of the distance to the source. This amounts to a reduction of 2.5 mag/arcsec2 in sky brightness for every log10 unit increase of the distance. The effects of screening by obstacles are also discussed.

Emergence of coexisting percolating clusters in networks

description: It is commonly assumed in percolation theories that at most one percolating cluster can exist in a network. We introduce sausage-like networks (SLNs), an ensemble of synthetic modular networks in which more than one percolating cluster can appear. We show that coexisting percolating clusters (CPCs) emerge in such networks due to limited mixing, i.e., a small number of interlinks between pairs of modules. We develop an approach called modular message passing (MMP) to describe and verify these observations. We demonstrate that the appearance of CPCs is an important source of inaccuracy in the previously introduced percolation theories, such as the message passing (MP) approach. Moreover, we show that the MMP theory improves significantly over the predictions of MP for percolation on synthetic networks with limited mixing and also on several real-world networks. These findings have important implications for understanding the robustness of networks and in quantifying epidemic outbreaks in the susceptible-infected-recovered (SIR) model of disease spread.
