A Systematic Review of Barriers and Interventions towards Eliminating Mother-to-Child HIV Transmission in the United States
Creators: name: Wynn, Bridget

Year: 2015

description: Mother-to-child transmission of HIV is a persistent public health issue in the United States, where 151 children were estimated to be infected in 2009. The CDC has defined elimination of mother-to-child transmission of HIV as rates below 1 in 100,000 children. Currently, the United States has a rate of approximately 2.2/100,000. The rate has fallen since the epidemic began, but is above what is achievable. Each transmission is a sentinel public health event, and represents missed opportunities for intervention. This paper provides a systematic review of the literature examining barriers that currently exist towards eliminating cases and opportunities to improve service implementation. This paper will also analyze successful interventions with evidence based practice that can be implemented towards eliminating mother-to-child HIV transmission. Although major inroads to reduce transmission events have occurred in the US over the last two decades, preventable cases remain. The CDC has developed a framework to eliminate mother-to-child transmission. The framework identifies a cascade of events for preventing the transmission of mother to child HIV infection. The framework also identifies areas where local health departments and health care providers may have failed to identify HIV-infected mothers and opportunities to improve. In the last decade, research has focused on specific best-practices targeting racial disparities and other tangible mechanisms for implementing effective interventions in the United States, within local health departments and across health care providers who work with women of childbearing age that are either HIV infected or at risk for infection to eliminate mother-to-child HIV transmission. This systematic review analyzed research from three databases from 2006 to present that show successful targeting of barriers and implementation of interventions that resulted in either: a) reduced mother-to-child HIV transmission; or b) the implementation of evidence-based practices, including the CDC framework.

description: Characterizing solar cells in real AMO environment is cost-effective with respect to ground measurements. For this reason, we designed a balloon-borne test facility to perform I/V curve characterization of solar cells in the stratospheric environment. This paper outlines the design of the facility and the results of a successful first flight that carried three different cells to an altitude of 35 km. The data collected show that peak power is achieved inside the tropopause, where the extreme cold conditions are favorable, rather than at higher altitudes, where -in spite of the higher irradiance -the cells tend to overheat.

description: An edge-coloured graph $G$ is rainbow connected if there exists a rainbow path between any two vertices. A graph $G$ is said to be $k$-rainbow connected if there exists an edge-colouring of $G$ with at most $k$ colours that is rainbow connected. For integers $n$ and $k$, let $t(n,k)$ denote the minimum number of edges in $k$-rainbow connected graphs of order $n$. In this note, we prove that $t(n,k) = \lceil k(n-2)/(k-1) \rceil$ for all $n, k \ge 3$

Barriers to Wellness Amongst Military Hospital Employees

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Multiple studies have investigated perceived barriers to employees participating in wellness activities at the workplace and have shown these barriers to have significant effect on human behavior, lack of physical activity and overall lifestyles. Research on specific barriers to wellness has taken place in unique employer environments, including those analyzing wellness among shift workers, but there is a lack of evidence evaluating specific barriers faced by personnel working in a military hospital. In partnership with US Army Public Health Command, we surveyed both uniformed and civilian workers in a military hospital to determine what barriers to wellness, specifically physical activity, exist. We asked questions, performed analysis on how to best mitigate these barriers, and investigated the correlation that exists between the barriers and overall perceived health. Our analyses indicate that time and lack of motivation are the most common barriers to physical activity. Additionally, as the number of barriers to physical activity increase, so does the likelihood that employees perceive themselves as being unhealthy. Key Words: Wellness, work-place wellness, physical activity, barriers to physical activity, perceived health
Merging of the Dirac points in electronic artificial graphene

description: Theory predicts that graphene under uniaxial compressive strain in an armchair direction should undergo a topological phase transition from a semimetal into an insulator. Due to the change of the hopping integrals under compression, both Dirac points shift away from the corners of the Brillouin zone towards each other. For sufficiently large strain, the Dirac points merge and an energy gap appears. However, such a topological phase transition has not yet been observed in normal graphene (due to its large stiffness) neither in any other electronic system. We show numerically and analytically that such a merging of the Dirac points can be observed in electronic artificial graphene created from a two-dimensional electron gas by application of a triangular lattice of repulsive antidots. Here, the effect of strain is modeled by tuning the distance between the repulsive potentials along the armchair direction. Our results show that the merging of the Dirac points should be observable in a recent experiment with molecular graphene.

FOLDING WING-TIPS

description: The current demand for highly efficient and \'green\' aircraft with less fuel bum calls for innovative wing solutions with improved overall performance. The Semi-Aeroelastic Hinge (SAH) concept has consistently demonstrated promising outcomes in terms of the load alleviation and an improvement in roll performance. This device employs floating folding wingtips as an in-flight load alleviation device such that the hinge will be released during manoeuvres and severe gusts to reduce aerodynamic loads, whilst remain locked for cruise to obtain the optimum wing shape. This paper develops a scaling approach for such wing configurations which allows for the development of scaled wind tunnel models with equivalent aeroelastic behaviour to a full-size aircraft. A set of scaling laws are derived which are employed to scale a reference aircraft incorporating a SAH. Despite significant non-linearities due to large wingtip fold angles, it was found that the linear scaling approach is applicable, and reasonable agreement is obtained between the aeroelastic behaviours of the scaled model and full-size aircraft.

description: Tensor networks implementing quantum error correcting codes have recently been used to construct toy models of holographic duality explicitly realizing some of the more puzzling features of the AdS/CFT correspondence. These models reproduce the Ryu-Takayanagi entropy formula for boundary intervals, and allow bulk operators to be mapped to the boundary in a redundant fashion. These exactly solvable, explicit models have provided valuable insight but nonetheless suffer from many deficiencies, some of which we attempt to address in this article. We propose a new class of tensor network models that subsume the earlier advances and, in addition, incorporate additional features of holographic duality, including: (1) a holographic interpretation of all boundary states, not just those in a "code" subspace, (2) a set of bulk states playing the role of "classical geometries" which reproduce the Ryu-Takayanagi formula for boundary intervals, (3) a bulk gauge symmetry analogous to diffeomorphism invariance in gravitational theories, (4) emergent bulk locality for sufficiently sparse excitations, and (5) the ability to describe geometry at sub-AdS resolutions or even flat space.

What Makes Adolescent-Targeted Anti-Tobacco Advertisements Effective? A Systematic Review and Qualitative Analysis
Creators: name: Quattlebaum, Robert G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Context: In the CDC's 2003 YRBSS report, 25% of North Carolina adolescents smoked a cigarette in the last month, slightly higher than the national average of 22%. Evidence is growing that mass media campaigns can reduce adolescent smoking, especially when used in combination with other programs. Objective: This project has two objectives. First, this project aims to determine what dimensions of an adolescent-targeted anti-tobacco advertisement are the most effective at preventing adolescent smoking. Second, this project aims to develop ideas that would target the North Carolina adolescent population. Design: The study consists of three phases: a systematic review, expert interviews, and a Photovoice study of the smoking-related cancer population. The systematic review utilized three search strategies: (1) journal databases, (2) the snowball technique, and (3) recommendations from expert interviews. Any study was included in the review if it evaluated the effectiveness of a dimension of a television advertisement in influencing the smoking behavior, intentions to change smoking behavior, attitudes about smoking, recall of advertisements, or perceived effectiveness of advertisements in young people less than 18 years of age. Experts for the interviews were selected from the research and based on local expert recommendations. They were interviewed using a standardized interview process. The Photovoice project utilized the PAR approach to develop potential ideas for the North Carolina Anti-tobacco Campaign. The results from both of these phases were analyzed using ATLAS-ti. Participants: One participant, a laryngectomy survivor, volunteered for the Photovoice project. Results: Five dimensions were found to be critical for advertisements: Production quality, Theme, Format, Emotional Tone, and Actor Characteristics. The serious health consequences theme, testimonial format, and real actor were the most effective means of targeting adolescents. The Photovoice developed ideas along these dimensions and revealed that concern of water and loss of voice would make effective anti-tobacco messages. Conclusions: This project provides evidence-based advertisement recommendations and outlines a theoretical framework for the development of an effective, adolescent-targeted anti-tobacco mass media campaign.

description: The year 2015 was the International Year of Light. It marked, however, also the 20th anniversary of the first observation of Bose-Einstein condensation in atomic vapors by Eric Cornell, Carl Wieman and Wolfgang Ketterle. This discovery can be considered as one of the greatest achievements of quantum optics that has triggered an avalanche of further seminal discoveries and achievements. For this reason we devote this essay for focus issue on "Quantum Optics in the International Year of Light" to the recent revolutionary developments in quantum optics at the frontiers of all physics: atomic physics, molecular physics, condensed matter physics, high energy physics and quantum information science. We follow here the lines of the introduction to our book "Ultracold atoms in optical lattices: Simulating quantum many-body systems" [1]. The book, however, was published in 2012, and many things has happened since then -- the present essay is therefore upgraded to include the latest developments.

Alcohol Prevention in the Workplace: The Role of the Occupational and Environmental Health Nurse
Creators: name: Trouslot, Saundra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Alcohol abuse impacting the workplace is not a new concept. In the late 1940s and early 1950s, the National Council on Alcoholism and Drug Dependence Inc. (NCADD) (n.d.) proposed that the workplace was the perfect setting to assist with alcohol dependency problems. From this, the first Employee Assistance Programs (EAPs), known as Occupational Alcoholism Programs at the time, were founded. Prevention and early intervention of alcohol-related problems have the potential to affect not only the workplace, but also society as a whole. Of the millions of individuals in the U.S. workforce, approximately 15 million or 6.6% of full-time and 4.9% of part-time employees admit to being heavy drinkers (NCADD, n.d.). In 2006, the reported estimated costs associated with alcohol abuse in workplace were approximately $223.5 billion (CDC, 2012a). Even with EAPs in the workplace, the costs and injury associated with alcohol abuse continue to rise. A change is needed and the answer may lie in the role and guidance of the occupational and environmental health nurse (OEHN). As a workplace advocate, the nurse can be instrumental in planning, implementing, and evaluating alcohol education and prevention programs, which can decrease the mounting costs to organizations from employee alcohol use and abuse.

description: The cathode air supply of a fuel cell system is modelled as a compressor-volume-throttle system with individual plena and spool dynamics. For both the throttle valve and the compressor, transfer functions describing their transient behavior have been established. The parameters of the model have been identified. The model was implemented and validated against measurement data. The results show concurrence of the compressor speed, valve opening angle, pressure rise, and mass flow in simulation and measurement. The model can be used in the development of an automatic control system, and is low in computational effort.

description: A thermal management system (TMS) is required to manage the heat loads of aircraft electric powertrain components. The specific heat rejection is used to describe the mass penalty of the TMS. A liquid cooled generic TMS architecture is defined with its components either modelled analytically or based on empirical scaling expressions. The TMS specific heat rejection is evaluated across various input parameters such as the heat flow, the fluid temperatures and the pipe dimensions. As a result trade-off options can be identified to reduced the overall system mass and are used to define design recommendations for TMSs to increase the specific heat rejection.

description: Several technical reports have raised concerns about the ejection of a significant amount of residual slag from a solid rocket motor (SRlvf) at the end of combustion, which contributes to the growing space debris problem. The E-31 static firing test have demonstrated a remarkable reduction in residual slag by using advanced propellant with improved aluminum combustion efficiency. E-31 will be adopted for orbital insertion stage for Japan\'s upcoming flagship solid propellant launcher known as Epsilon S. Experimental findings have validated that in SRMs that selects a propellant that can achieve such high aluminum combustion efficiency, the acceleration sensitivity to aluminum/alumina particles flying inside the combustion chamber drops to a level that cannot be distinguished from the range of variations. Consequently, contrary to the past technical reports, the estimated quantity of residual slag inside the SRM during flight is considered to have a minimal adverse impact on the orbital environment.

Extensive photometry of the WZ Sge-type dwarf nova V455 And (HS2331+3905): detection of negative superhumps and coherence features of the short-period oscillations

description: We report the results of photometry of the WZ Sge-type dwarf nova V455 And. Observations were obtained over 19 nights in 2013 and 2014. The total duration of the observations was 96 h. We clearly detected three coherent oscillations with periods of 80.376+/-0.003 min, 40.5431+/-0.0004 min and 67.619685+/-0.000040 s. The 67.619685-s period can be the spin period of the white dwarf. The 40.5431-minute period is the first harmonic of the orbital period. The 80.376-minute oscillation can be a negative superhump because its period is 0.9% less than the orbital period. This oscillation was evident both in the data of 2013 and in the data of 2014. These results make V455 And a permanent superhump system which shows negative superhumps. This is also the first detection of persistent negative superhumps in a WZ Sge-type dwarf nova. In addition, the analysis of our data revealed incoherent oscillations with periods in the range 5-6 min, which were observed earlier and accounted for by non-radial pulsations of the white dwarf. Moreover, we clearly detected an oscillation with a period of 67.28+/-0.03 s, which was of a low degree of coherence. This oscillation conforms to the beat between the spin period of the white dwarf and the 3.5-h spectroscopic period, which was discovered earlier and accounted for by the free precession of the white dwarf. Because the 67.28-s period is shorter than the spin period and because the free precession of the white dwarf is retrograde, we account for the 67.28-s oscillation by the free precession of the white dwarf.

description: State selective protocols, like entanglement purification, lead to an essentially non-linear quantum evolution, unusual in naturally occurring quantum processes. Sensitivity to initial states in quantum systems, stemming from such non-linear dynamics, is a promising perspective for applications. Here we demonstrate that chaotic behaviour is a rather generic feature in state selective protocols: exponential sensitivity can exist for all initial states in an experimentally realisable optical scheme. Moreover, any complex rational polynomial map, including the example of the Mandelbrot set, can be directly realised. In state selective protocols, one needs an ensemble of initial states, the size of which decreases with each iteration. We prove that exponential sensitivity to initial states in any quantum system have to be related to downsizing the initial ensemble also exponentially. Our results show that magnifying initial differences of quantum states (a Schrödinger microscope) is possible, however, there is a strict bound on the number of copies needed.

description: In this paper we present multi-band period-luminosity (P-L) relations for fundamental mode Cepheids in the SMC. The optical VI-band mean magnitudes for these SMC Cepheids were taken from the third phase of the Optical Gravitational Lensing Experiment (OGLE-III) catalog. We also matched the OGLE-III SMC Cepheids to 2MASS and SAGE-SMC catalog to derive mean magnitudes in the JHK-bands and the four {\it Spitzer} IRAC bands, respectively. All photometry was corrected for extinction by adopting the Zaritsky's extinction map. Cepheids with periods smaller than $\sim2.5$ days were removed from the sample. In addition to the extinction corrected P-L relations in nine filters from optical to infrared, we also derived the extinction-free Wesenheit function for these Cepheids. We tested the nonlinearity of these SMC P-L relations (except the $8.0μ\mathrm{m}$-band P-L relation) at 10 days: none of the P-L relations show statistically significant evidence of nonlinearity. When compared to the P-L relations in the LMC, the t-test results revealed that there is a difference between the SMC/LMC P-L slopes only in the V- and J-band. Further, we found excellent agreement between the SMC/LMC Wesenheit P-L slope. The difference in LMC and SMC Period-Wesenheit relation LMC and SMC zero points was found to be $Δμ=0.483\pm0.015$ mag. This amounts to a difference in distance modulus between the LMC and SMC.

description: We report the properties of emission lines associated with the cascaded recombination of a quadexciton in single GaAlAs/AlAs quantum dots, studied by means of polarization-resolved photoluminescence and single-photon correlation experiments. It is found that photons which are emitted in a double-step 4X-3X process preserve their linear polarization, similarly to the case of conserved polarization of correlated photons in the 2X-X cascade. In contrast, an emission of either co-linear or cross-linear pairs of photons is observed for the 3X-2X cascade. Each emission line associated with the quadexciton cascade shows doublet structure in the polarization-resolved photoluminescence experiment. The maximum splitting is seen when the polarization axis is chosen along and perpendicular to the [110] crystallographic direction. This effect is ascribed to the fine structure splitting of the exciton and triexciton states in the presence of an anisotropic confining potential of ae dot. We also show that the splitting in the triexciton state surpasses that in the exciton state by a factor up to eight and their ratio scales with the energy distance between the 3X and X emission lines, thus, very likely, with a lateral size and/or a composition of the dot.

description: Liver fat is recognized as a separate and important contributor to metabolic disease development. The liver is an insulin responsive tissue that contributes significantly to both whole body insulin sensitivity and availability of sex steroids through the production of sex hormone binding globulin (SHBG). Our objective was to describe the relationship between ectopic liver fat, insulin resistance, and hormonal profile in perimenopausal women. The Study of Women Across the Nation (SWAN) is a cross sectional multiethnic population of women recruited from multiple geographic areas during their perimenopausal years for longitudinal evaluation. A subset of women from SWAN (n=208) were evaluated from the Pittsburgh site as part of the SWAN-Heart study. Women had computed tomography scans to quantify visceral and subcutaneous adipose tissue, and liver fat. Adiposity measures, blood pressure, and menopausal stage, based on cycle irregularity, were recorded. Blood samples were collected and measured for hormonal and metabolic endpoints. We found in this overweight but healthy cohort that liver fat and SHBG were unaffected by menopausal stage or race. Both endpoints remained significantly associated with insulin after adjustment for adiposity. SHBG and liver fat had interactive effects on measured insulin concentration. Other sex hormones were not significantly associated with metabolic endpoints. Only liver fat accounted for differences in insulin across increasing SHBG quartiles, suggesting ectopic liver fat modifies SHBG. Both higher liver fat and lower SHBG have consequences for insulin sensitivity and the role of liver fat in modifying SHBG should be explored.

Jimenez Garcia, Juan Manuel 1 Airbus Helicopters Espana SAU, Carretera de las Pefias km. 5,3 Parque Aeronautico y Logistico 02006 ALBACETE I (JMJG) * Juan Manuel Jimenez Garcia (JMJG) juan-manuel.jimenez@airbus.com The RACER demonstrator (Rapid and Cost Effective Rotorcraft) is the answer from Airbus Helicopters to the need of High Speed Rotary-Wing Aircrafts. It is a Technological Demonstrator, in which are implemented a no minor quantity of innovations, RACER will perform its first flight by the end of 2023 within the European initiative of Clean Sky 2. This paper will show the characteristics and developments of the RACER, as an advanced formula of Gyrodyne patented by Airbus Helicopters. A comparison will also be made between the solutions of the European competitors and the FVL (Future Vertical Lift) of USA. It will be made an introduction about its main features for developing dual operations, as well as mission performance, aerodynamics and structure. Moreover, a general description of the structural fuselage breakdown will be done, with special focus on the basic structural layout and the main component developed, manufactured and assembled in Spain: the rear fuselage. The rear fuselage is a complex, disruptive and efficient airframe that plays a key role in the RACER, contributing to reinforce its dual nature. This fuselage includes several patents and innovative developments such as asymmetric transversal sections for the tail boom and double-tilted empennage in \"H\" configuration, which is pioneer in the implementation of Out of Autoclave (OoA) technologies for big dimensions and complexity (primary structure of the Empennage ), also the implementation of the first primary structure (class 2 part) developed by Additive Manufacturing which will be the first item in this technology that ever has flight in Airbus Helicopters. The description of the main components of the rear fuselage will include information about the details of the design and production, testing and certification, in addition to the innovative challenges dealt as it has been already mentioned.

description: This work presents an investigation of alternative propulsion systems with the focus on technology scaling opportunities across different aircraft categories. Combining the conceptual aircraft design capabilities at Politecnico di Milano and the system architecture sizing and evaluation tools at Collins Aerospace, five aircraft categories are studied based on six novel propulsion system architectures considering different future technology scenarios. The results suggest that hydrogen-powered architectures combined with a customized utilization of fuel cells have the potential to reduce mission energy and thereby climate impact making them a promising option to reach sustainability goals.

description: Space flight is at a turning point in history. On the one hand, more space systems are being launched than ever before. This trend will continue in the coming years due to the increased interest in satellite constellations and space exploration. On the other hand, spaceflight in Europe is facing the challenge of reducing its environmental impact. A significant part of this impact is caused by production, which is analyzed in this study. This paper is the first scientific publication that analyzes the production of launchers with respect to the absolute impact as well as the share of subsystems. In addition, different launcher system architectures and propellants are compared for the first time in order to provide recommendations for the environmentally friendly development of launcher systems. The methodology presented for calculating the environmental impact of launchers during the design phase is therefore a novelty. For this purpose, generic environmental indicators developed on Ariane 6 version A64 production provided by ArianeGroup are used. These data were determined for all important subsystems to enable a comparison between different launcher architectures. The study defines different typical target orbits, staging concepts and propellants as a framework for this study. In the following step, different launcher architectures are designed using common design formulas and subsystem mass distribution. Finally, their environmental impact is then estimated using 19 indicators. In the final step, a detailed analysis of the share of subsystem and manufacturing processes is made as well as a comparison of different launcher architectures and propellant systems for one ton of payload into a different orbit.

description: The wings of aircraft should have sufficient mechanical properties and should not fail, but they should be lightweight. The three-dimensional woven composite has excellent formability and outstanding utilization by the automated manufacturing process based on the preform. In addition, it has high outof-plane mechanical properties due to the three-dimensional fiber arrangement. In this paper, the optimal design was performed using a genetic algorithm to reduce the weight of the aircraft wing in threedimensional woven composite. Through the optimal design, we can build a database of mechanical properties and the wing\'s mass according to the number of fill yarn layers.
