description: We consider two coupled time reversal invariant helical edge modes of the same helicity, such as would occur on two stacked quantum spin Hall insulators. In the presence of interaction, the low energy physics is described by two collective modes, one corresponding to the total current flowing around the edge and the other one describing relative fluctuations between the two edges. We find that quite generically, the relative mode becomes gapped at low temperatures, but only when tunneling between the two helical modes is non-zero. There are two distinct possibilities for the gapped state depending on the relative size of different interactions. If the intra-edge interaction is stronger than the inter-edge interaction, the state is characterised as a spin-nematic phase. However in the opposite limit, when the interaction between the helical edge modes is strong compared to the interaction within each mode, a spin-density wave forms, with emergent topological properties. Firstly, the gap protects the conducting phase against localization by weak nonmagnetic impurities; and secondly the protected phase hosts localized zero modes on ends of the edge that may be created by sufficiently strong non-magnetic impurities.

description: Malnutrition is a worldwide concern that affects millions of children and adversely influences physical and mental growth that will shape that individual for the rest of their life. In Peru, 31% of children under the age of five are considered malnourished and over three-fourths of those children are suffering from moderate to severe stunting due to poor nutritional intake. Complementary feeding practices have been evaluated and accepted by the World Health Organization as necessary practices for caregivers with children 6-24 months of age in order to to address malnutrition in children; however wide-scale implementation and evaluation is necessary to incorporate these practices into every day feeding methods. Further research on the practice of responsive feeding is needed to evaluate whether the interaction between the caregiver and child during feeding episodes affects the nutritional status of a child. While research is being conducted through the Instituto de Investigación Nutricional in Lima, Peru and should be presented as early as June 2009, programs should be implemented immediately to begin incorporating these techniques into common cultural practices.

description: Structural health monitoring (SHM) has been an active research area for the last three decades, and has accumulated a number of critical advances over that period, as can be seen in the literature. However, SHM is still facing challenges because of the paucity of damage-state data, operational and environmental fluctuations, repeatability issues, and changes in boundary conditions. These issues present as inconsistencies in the captured features and can have a huge impact on the practical implementation, but more critically, on the generalisation of the technology. Population-based SHM has been designed to address some of these concerns by modelling and transferring missing information using data collected from groups of similar structures. In this work, vibration data were collected from four healthy, nominally-identical, full-scale composite helicopter blades. Manufacturing differences (e.g., slight differences in geometry and/or material properties), among the blades presented as variability in their structural dynamics, which can be very problematic for SHM based on machine learning from vibration data. This work aims to address this variability by defining a general model for the frequency response functions of the blades, called a form, using mixtures of Gaussian processes.

description: Neutrino oscillations are a widely observed and well established phenomenon. It is also well known that deviations with respect to flavor conversion probabilities in vacuum arise due to neutrino interactions with matter. In this work, we analyze the impact of new interactions between neutrinos and the dark matter present in the Milky Way on the neutrino oscillation pattern. The dark matter-neutrino interaction is modeled by using an effective coupling proportional to the Fermi constant $G_F$ with no further restrictions on its flavor structure. For the galactic dark matter profile we consider an homogeneous distribution as well as several density profiles, estimating in all cases the size of the interaction required to get an observable effect at different neutrino energies. Our discussion is mainly focused in the PeV neutrino energy range, to be explored in observatories like IceCube and KM3NeT. The obtained results may be interpreted in terms of a light $\mathcal{O}$(sub-eV--keV) or WIMP-like dark matter particle or as a new interaction with a mediator of $\mathcal{O}$(sub-eV--keV) mass.

description: Non-deterministic measurements are common in real-world scenarios: the performance of a stochastic optimization algorithm or the total reward of a reinforcement learning agent in a chaotic environment are just two examples in which unpredictable outcomes are common. These measures can be modeled as random variables and compared among each other via their expected values or more sophisticated tools such as null hypothesis statistical tests. In this paper, we propose an alternative framework to visually compare two samples according to their estimated cumulative distribution functions. First, we introduce a dominance measure for two random variables that quantifies the proportion in which the cumulative distribution function of one of the random variables stochastically dominates the other one. Then, we present a graphical method that decomposes in quantiles i) the proposed dominance measure and ii) the probability that one of the random variables takes lower values than the other. With illustrative purposes, we re-evaluate the experimentation of an already published work with the proposed methodology and we show that additional conclusions (missed by the rest of the methods) can be inferred. Additionally, the software package RVCompare was created as a convenient way of applying and experimenting with the proposed framework.
In Home Environmental Assessments: A Key Component of a Comprehensive Asthma Management Initiative
Creators: name: Mehta, Alka
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Asthma is one of the most common chronic diseases of childhood, and carries a high public health burden. Asthma is more prevalent and more severe in children from minority groups and those of lower socioeconomic status (Akinbami, 2009). Direct and indirect health care costs of asthma in the US total more than $18 billion per year (AAAAI, 2009). Although it is not a curable illness, it can be effectively managed with comprehensive care that includes medical management, education, and environmental modifications. In 2007, national asthma management guidelines were modified to include environmental trigger identification and remediation as a critical component of asthma care. This is based on a growing body of evidence that suggests that reduction of indoor environmental triggers in the home environment of children with asthma may lead to a decrease in asthma-related morbidity and in asthma-related health care costs. A home visit is an optimal setting to provide patient education and to identify and mitigate the effects of environmental triggers in the home. In the last several years, a number of research studies and programs have attempted home-based interventions that provide a combination of tailored home environmental assessments, patient education, and supplies to reduce indoor allergens. Using these experiences as a starting point, Community Care of Wake and Johnston Counties is in the process of developing and implementing an asthma initiative that focuses on indoor environmental trigger reduction through home assessments and case management. This paper will focus on the planning and development of a program and evaluation plan for a multifaceted in home environmental intervention for Wake County children with asthma.

description: Recently, a new method for calculating the Cherenkov field acting on a point-like electron bunch passing through longitudinally homogeneous structures lined with arbitrary slowdown layers was proposed, where the formalism was obtained though consideration of a general integral relation that allows calculation of the fields at the vicinity of a point-like bunch. It demonstrates that the Cherenkov field at the point of the short relativistic bunch does not depend on the waveguide system material and is a constant for any given transverse dimensions and cross-section shapes of waveguides. With this paper we present a strict derivation of the fields formulas valid at the cross-section of a bunch on the basis of a conformal mapping method. We generalize the results of the previous paper to the case of transversely distributed bunch by deriving a two-dimensional Green function at the cross-section of a bunch. Comparison of the results proving validity of the method is given in the appendix.

description: Along with the rapid growth and rise to prominence of food delivery platforms, concerns have also risen about the terms of employment of the gig workers underpinning this growth. Our analysis on data derived from a real-world food delivery platform across three large cities from India show that there is significant inequality in the money delivery agents earn. In this paper, we formulate the problem of fair income distribution among agents while also ensuring timely food delivery. We establish that the problem is not only NP-hard but also inapproximable in polynomial time. We overcome this computational bottleneck through a novel matching algorithm called FairFoody. Extensive experiments over real-world food delivery datasets show FairFoody imparts up to 10 times improvement in equitable income distribution when compared to baseline strategies, while also ensuring minimal impact on customer experience.

description: There are large number of proteins, the existence of which are known but not their crystal structure, because of difficulty in finding the exact condition for their crystallization. Heterogeneous nucleation on disordered porous substrates with small yet large distribution of pores is considered a panacea for this problem, but a universal nucleant, suitable for crystallizing large variety of proteins does not really exist. To this end, we report here a nano-wrinkled substrate which displays remarkable ability and control over protein crystallization. Experiments with different proteins show that on these substrates, crystals nucleate even at very low protein concentration in buffer. Small number of very large crystals appear for precipitant concentrations varied over orders of magnitude ~0.003-0.3M; for some proteins, crystals appear even without addition of any precipitant, not seen with any other heterogeneous substrates. In essence, these substrates significantly diminish the influence of the above two parameters, thought to be key factor for crystallization, signifying that this advantage can be exploited for finding out crystallization condition for other yet-to-be-crystallized proteins.

description: We consider soft-core bosons with onsite interaction loaded in the honeycomb lattice with different site energies for the two sublattices. Using both a mean-field approach and quantum Monte-Carlo simulations, we show that the topology of the honeycomb lattice results in a non-vanishing Berry curvature for the band structure of the single-particle excitations of the system. This Berry curvature induces an anomalous Hall effect. It is seen by studying the time evolution of a wavepacket, namely a superfluid ground state in a harmonic trap, subjected either to a constant force (Bloch oscillations) or to a sudden shift of the trap center.

Discovery of a Strongly Lensed Massive Quiescent Galaxy at z=2.636: Spatially Resolved Spectroscopy and Indications of Rotation

description: We report the discovery of RG1M0150, a massive, recently quenched galaxy at z=2.636 that is multiply imaged by the cluster MACSJ0150.3-1005. We derive a stellar mass of log M_*=11.49+0.10-0.16 and a half-light radius of R_e,maj =1.8+-0.4 kpc. Taking advantage of the lensing magnification, we are able to spatially resolve a remarkably massive yet compact quiescent galaxy at z>2 in ground-based near-infrared spectroscopic observations using Magellan/FIRE and Keck/MOSFIRE. We find no gradient in the strength of the Balmer absorption lines over 0.6 R_e - 1.6 R_e, which are consistent with an age of 760 Myr. Gas emission in [NII] broadly traces the spatial distribution of the stars and is coupled with weak Halpha emission (log [NII]/Halpha = 0.6+-0.2), indicating that OB stars are not the primary ionizing source. The velocity dispersion within the effective radius is sigma_e = 271+-41 km/s. We detect rotation in the stellar absorption lines for the first time beyond z~1. Using a two-integral Jeans model that accounts for observational effects, we measure a dynamical mass of log M_dyn =11.24+-0.14 and V/sigma=0.70+-0.21. This is a high degree of rotation considering the modest observed ellipticity of 0.12+-0.08, but it is consistent with predictions from dissipational merger simulations that produce compact remnants. The mass of RG1M0150 implies that it is likely to become a slowly rotating elliptical. If it is typical, this suggests that the progenitors of massive ellipticals retain significant net angular momentum after quenching which later declines, perhaps through accretion of satellites.

description: We determine the full kinetic phase diagram for nucleation and growth of crystal phases in a suspension of charged colloids. We calculate nucleation barrier heights for face-centered cubic (fcc) and body-centered cubic (bcc) crystal phases for varying screening lengths and supersaturations using the seeding approach in extensive simulations. Using classical nucleation theory, we determine for the entire metastable fluid region the crystal polymorph with the lowest nucleation barrier. Surprisingly, we find a regime close to the triple point where metastable bcc can form due to a lower nucleation barrier, even though fcc is the stable phase. For higher supersaturation, we find that the difference in barrier heights decreases and we observe a mix of hexagonal close-packed (hcp), fcc and bcc structures in the growth of crystalline seeds as well as in spontaneously formed crystals.

description: We report on properties of an optical microcavity based on (Cd,Zn,Mg)Te layers and embedding (Cd,Zn)Te quantum wells. The key point of the structure design is the lattice matching of the whole structure to MgTe, which eliminates the internal strain and allows one to embed an arbitrary number of unstrained quantum wells in the microcavity. We evidence the strong light-matter coupling regime already for the structure containing a single quantum well. Embedding four unstrained quantum wells results in further enhancement of the exciton-photon coupling and the polariton lasing in the strong coupling regime.
The Aging Workforce: Implications for the Occupational and Environmental Health Nurse
Creators: name: Bull, Lisa W.

Year: 2009

description: The U.S. population is aging and so too is the U. S. labor force. Workers are remaining on the job and in the workforce longer because of increasing life expectancies, necessity, and desire. In 2006, the labor force participation rate for those 55 years and older was 38%. This number, according to the Bureau of Labor Statistics, will rise to almost 43% by 2016 (Toosi, 2007). Employees and employers must be prepared to face the benefits and challenges that arise with an aging workforce. Understanding the cognitive and physiologic changes that occur with aging is important to the successful employment of aging workers. As the labor force ages, many opportunities and challenges arise in the work environment. Employers benefit from the aging workers' expertise, experiences, and loyalty. However, workplace injuries and illness, workers' compensation costs, and health care costs are significant issues for both the employee and employer. The occupational and environmental health nurse (OEHN) is uniquely positioned to assist both employee and employer in the identification and elimination of workplace injuries and in the design and implementation of strategies and programs to promote health and wellness. The OEHN may assume many roles to successfully meet the health and safety needs of the aging worker including clinician/practitioner, leader, health promotion specialist, educator, and collaborator.

title: Guardians of the Countryside Public Choice Theory and the Farm Lobby in the EU's Common Agricultural Policy
Creators: name: Costa, Amy J.
Publisher: name: Old Dominion University Libraries
Year: 2012

description: Through various waves of reform, the European Union's Common Agricultural Policy remains inefficient without meeting all of its stated goals. The MacSherry reforms of 1992 resulted in the opposite of what leaders intended: higher spending and a growing bureaucracy. Later in the 1990s, Agenda 2000 slashed its originally planned cutbacks after farmers protested. Though support exists for reducing spending on agriculture, market intervention remains.

This thesis explores the problem through the use of public choice theory. -Consumers make too large a group to organize effectively or inform themselves about the issue, while farmers consist of a smaller group with well-defined interests. Because they cannot get as much income as they would wish from the market, farmers engage in rent-seeking behavior in hopes of receiving income from the state. Due to their smaller size, . they find ease in organization, giving them a better bargaining position than consumers when it comes to lobbying for agricultural subsidies.

In addition to the standard Kirchhoff model with the Sobolev point condition, a three-dimensional boundary layer is investigated in the vicinity of the support $θ_{h}$, which with the help of the derived weighted inequality of Korn's type, will provide an error estimate with the bound $ch^{1/2}|\ln h|$. Ignoring this boundary layer effect reduces the precision order down to $|\ln h|^{-1/2}$.

Early Screening for Gestational Diabetes Mellitus: A Systematic Review
Creators: name: Kelley, Dana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: BACKGROUND: Gestational diabetes mellitus (GDM) is diabetes that is diagnosed for the first time during pregnancy. Rates of GDM in the U.S. and internationally have been rising in recent years. GDM is associated with an increased risk of adverse pregnancy outcomes, an increased risk of maternal Type 2 Diabetes Mellitus in the future, as well as an increased risk of future chronic disease for the neonate. Although recommendations differ, most guidelines recommend screening women with an oral glucose tolerance test during the second trimester and advise earlier screening in women considered high-risk for developing GDM. AIMS: The objective of this systematic review will be to evaluate the accuracy of various methods of early screening for GDM as compared with traditional screening during the second trimester, and to determine whether earlier screening leads to improved maternal-fetal health outcomes. METHODS: PubMed and the Cochrane Library were systematically searched according to pre-established eligibility criteria. Hand searches of relevant references and the grey literature were also done. One reviewer examined abstracts for eligibility and abstracted relevant data from included articles. Each included articles was assessed for quality. RESULTS: Data on the accuracy and predictive ability of early screening was mixed. Early screening was done most often using fasting plasma glucose, however cutoff values that predicted gestational diabetes varied widely. Oral glucose tolerance testing and glycosylated hemoglobin were used infrequently as an early screening test. Though the data were also mixed on pregnancy outcomes associated with early screening, no outcomes were consistently shown to be improved through the process of early screening. CONCLUSIONS: Due to heterogeneity of methods and inconsistent outcomes with early gestational diabetes screening, no method may conclusively be put forth as a superior method of screening for gestational diabetes early in pregnancy. Additionally, at this point, early screening overall cannot be justified due to a lack of evidence of improvement in maternal and neonatal outcomes. Future research should include better study designs, with more attention paid to clinically significant outcomes for women and their babies.

description: A novel approach to investigate the electron transport of cis- and trans-polyacetylene chains in the single-electron approximation is presented by using microwave emulation measurements and tight-binding calculations. In the emulation we take into account the different electronic couplings due to the double bonds leading to coupled dimer chains. The relative coupling constants are adjusted by DFT calculations. For sufficiently long chains a transport band gap is observed if the double bonds are present, whereas for identical couplings no band gap opens. The band gap can be observed also in relatively short chains, if additional edge atoms are absent, which cause strong resonance peaks within the band gap. The experimental results are in agreement with our tight-binding calculations using the nonequilibrium Green's function method. The tight-binding calculations show that it is crucial to include third nearest neighbor couplings to obtain the gap in the cis-polyacetylene.

However, the reduction of cervical cancer incidence and mortality in this region has not been as successful as that achieved in developed countries, as cervical cancer remains the first or second leading cause of death due to cancer for Latin American women (Yunes-Díaz, Ruiz, & Lazcano-Ponce, 2015). Multiple studies have established that the Pap smear has a low sensitivity (40% to 80%) and a high false negative rate (25% to 50%) (Flores, et al., 2010; Murillo, Almonte, Pereira, Ferrer, Gamboa, Jerónimo & Lazcano-Ponce, 2008; Murillo, Herrero, Sierra & Forman, 2016). New emerging technologies, such as HPV testing, have demonstrated a greater sensitivity, and can identify high-grade cervical cancer earlier than Pap smears.   The purpose of this literature review was to analyze and compare the cost-effectiveness of Pap smear alone versus Pap smear combined with HPV testing as part of a standardized cervical cancer screening program in Latin America. A total of 30 articles and cost-effectiveness analyses were included in this literature review. The cost of Pap smear alone at first sight seems to be lower than that of HPV testing, but when the cost of false negatives is taken into account, the total costs associated with the Pap smear exceed those of other tests with fewer false negatives.  The use of the Pap smear and HPV testing combination ends up being less expensive for its potential to identify 98% of cervical cancer cases, which represents 64% more cases than the Pap test alone (Flores, et al., 2010; Goldie & Gaffikin, 2005; Granados-García, Flores, Pérez,  Rudolph, Lazcano-Ponce & Salmerón,  2014; Mandelblatt, Lawrence, & Gaffikin, 2002). Most of the reviewed cost-effective analyses indicate that including HPV testing into an already existing cervical cancer screening program could be a highly cost-effective screening alternative for most of the national health delivery institutions. These results may help policy-makers implement HPV testing as part of the cervical cancer screening programs in Latin America (Flores, et al., 2010).

description: Motivated by nucleation and molecular aggregation in physical, chemical and biological settings, we present an extension to a thorough analysis of the stochastic self-assembly of a fixed number of identical particles in a finite volume. We study the statistic of times it requires for maximal clusters to be completed, starting from a pure-monomeric particle configuration. For finite volume, we extend previous analytical approaches to the case of arbitrary size-dependent aggregation and fragmentation kinetic rates. For larger volume, we develop a scaling framework to study the behavior of the first assembly time as a function of the total quantity of particles. We find that the mean time to first completion of a maximum-sized cluster may have surprisingly a very weak dependency on the total number of particles. We highlight how the higher statistic (variance, distribution) of the first passage time may still help to infer key parameters (such as the size of the maximum cluster) from data. And last but not least, we present a framework to quantify the formation of cluster of macroscopic size, whose formation is (asymptotically) very unlikely and occurs as a large deviation phenomenon from the mean-field limit. We argue that this framework is suitable to describe phase transition phenomena, as inherent infrequent stochastic processes, in contrast to classical nucleation theory.

A Program Plan for the Mental Health Cooperative of North Carolina (MHCNC)

description: Mental health policy and reform has faced immense transformation since the early 1960s with the passage of law to deinstitutionalize treatment and replace care with more local, community-based treatments and interventions (Rash 2012). While this move has been positive for the state of North Carolina, the transition has not been easy. A historical examination of the state of mental health reform in North Carolina and an evaluation of the system’s key stakeholders reveals the ongoing efforts being made to improve the quality of care across the state by means of streamlining of the LME/MCO system. An analysis of the system’s strengths and weaknesses further highlights the success of community-based models in behavioral health interventions. Additionally, the paper discusses the need to mitigate fragmented stakeholder involvement, legislative uncertainty, and unsustainable funding. Recognizing the importance of cohesive stakeholder engagement, this paper recommends the establishment of the Mental Health Cooperative of North Carolina (MHCNC or the Cooperative) to augment the already successful work being done by care organizations and nonprofits. The Cooperative’s overall goal will be to identify community-based intervention successes across the state, document best practices, and assist care organizations in deploying workable solutions across the state. Underpinning the MHCNC’s success are theoretical frameworks and research evidence, such as community-based participatory research and the consolidated framework for implementation research that lend support to the Cooperative’s overall goal. While the anticipated outcomes of multilateral models are well documented, there are several limitations to address when assembling community actors. Therefore, it is through effective leadership that the MHCNC aspires to become a compelling advocate in North Carolina’s quest to deliver optimal mental health care within its counties.

description: We present a multi-layer mathematical model to describe the the transdermal drug release from an iontophoretic system. The Nernst-Planck equation describe the basic convection-diffusion process, with the electric potential obtained by Laplace equation. These equations are complemented with suitable interface and boundary conditions in a multi-domain. The stability of the mathematical problem is discussed in different scenarios and a finite-difference method is used to solve the coupled system. Numerical experiments are included to illustrate the drug dynamics under different conditions.

description: We study a synthetic system of motile Escherichia coli bacteria encapsulated inside giant lipid vesicles. Forces exerted by the bacteria on the inner side of the membrane are sufficient to extrude membrane tubes filled with one or several bacteria. We show that a physical coupling between the membrane tube and the flagella of the enclosed cells transforms the tube into an effective helical flagellum propelling the vesicle. We develop a simple theoretical model to estimate the propulsive force from the speed of the vesicles, and demonstrate the good efficiency of this coupling mechanism. Together, these results point to design principles for conferring motility to synthetic cells.

description: Gastric bypass is an increasingly popular treatment for morbid obesity, especially in smaller medical centers and community clinics. Evidence-based guidelines for gastric bypass post-operative follow-up are needed to help minimize complications from this high-risk surgical procedure. Long term outcomes research to develop such guidelines is lacking, and future research is especially needed to explore important patient-related factors needed for a successful post-operative follow-up protocol. We performed a systematic review of relevant studies and the results of a data analysis addressing appointment keeping behavior in gastric bypass patients in the University of North Carolina Hospitals Department of Gastrointestinal Surgery. We then conducted a stuffy to examine patient-level factors associated with no-show behavior at the 6 month post-operative appointment at a tertiary care hospital. Our goal was to determine if an association existed between non-attendance at the 6 month post-operative follow-up appointment and out-of-pocket patient expenses due at that appointment.

description: The structural, electronic, mechanical and thermal properties of Ir$_{1-x}$Rh$_{x}$ alloys were studied systematically using ab initio density functional theory at different concentrations (x = 0.00, 0.25, 0.50, 0.75, 1.00). A Special Quasirandom Structure method was used to make alloys having FCC structure with four atoms per unit cell. The ground state properties such as lattice constant and bulk modulus were calculated to find the equilibrium atomic position for stable alloys. The calculated ground state properties are in good agreement with the experimental and previously presented other theoretical data. The electronic band structure and density of states were calculated to study the electronic properties for these alloys at different concentrations. The electronic properties substantiate the metallic behavior of alloys. The first principle density functional perturbation theory as implemented in quasiharmonic approximation was used for the calculation of thermal properties. We have calculated the thermal properties such as Debye temperatures, vibration energy, entropy, constant-volume specific heat and internal energy. The ab initio linear-response method was used to calculate phonon densities of states.

description: A challenging case in web search and question answering are count queries, such as \textit{"number of songs by John Lennon"}. Prior methods merely answer these with a single, and sometimes puzzling number or return a ranked list of text snippets with different numbers. This paper proposes a methodology for answering count queries with inference, contextualization and explanatory evidence. Unlike previous systems, our method infers final answers from multiple observations, supports semantic qualifiers for the counts, and provides evidence by enumerating representative instances. Experiments with a wide variety of queries show the benefits of our method. To promote further research on this underexplored topic, we release an annotated dataset of 5k queries with 200k relevant text spans.
