description: Since September 11. 2001 there has been an increased threat of a chemical or biological attack on America. One of the most likely agents to be used in such an attack is smallpox. The federal government has developed guidelines to assist the state and local governments in rolling out a smallpox vaccination plan for their citizens. Each state invited all of their local health departments to develop a plan of vaccinating healthcare workers against smallpox. Outlined in the following sections are those federal, state, and local smallpox plans.

description: Measurements of the drift velocities of electrons and holes as functions of electric field and temperature in high-purity n- and p-type silicon with <100> crystal orientation are presented. The measurements cover electric field values between 2.4 and 50 kV/cm and temperatures between 233 and 333 K. Two methods have been used for extracting the drift velocities from current transient measurements: A time-of-flight (tof) method and fits of simulated transients to the measured transients, with the parameters describing the field and temperature dependence of the electron and hole mobilities as free parameters. A new mobility parametrization, which also provides a better description of existing data than previous ones, allowed an extension of the classical tof method to the situation of non-uniform fields. For the fit method, the use of the convolution theorem of Fourier transforms enabled us to precisely determine the electronics transfer function of the complete set-up, including the sensor properties. The agreement between the tof and the fit method is about 1 %, which corresponds to a time-of-flight uncertainty of 30 ps for a pad diode of 200 μm thickness at the highest voltages. Combining our results with published data of low-field mobilities, we derive parameterizations of the drift velocities in high-ohmic <100> silicon for electrons and holes for fields between 0 and 50 kV/cm and temperatures between 233 and 333 K.

description: We present the multi-band dual triply irreducible local expansion (D-TRILEX) approach to interacting electronic systems and discuss its numerical implementation. This method is designed for a self-consistent description of multi-orbital systems that can also have several atoms in the unit cell. The current implementation of the D-TRILEX approach is able to account for the frequency- and channel-dependent long-ranged electronic interactions. We show that our method is accurate when applied to small multi-band systems such as the Hubbard-Kanamori dimer. Calculations for the extended Hubbard, the two-orbital Hubbard-Kanamori, and the bilayer Hubbard models are also discussed.

Year: 2016

description: ABSTRACT Community Resources and Hospital Readmission Background: Cardiovascular disease (CVD) is one of the conditions that contribute most to the number of patient readmissions in the United States. Hospital and patient characteristics influence rehospitalization; in addition to major risk factors such as high blood pressure or high cholesterol, other factors such as age, ethnicity and socioeconomic status are associated with hospital readmission for CVD patients. Objective: The purpose of this study is to examine whether differences in community-level resources in disadvantaged neighborhoods is associated with 30-day hospital readmissions in patients with CVD. Design: Retrospective cohort study. Setting: Durham County and Granville County in the state of North Carolina. Patients: Patients from Durham County and Granville County admitted for CVD to Duke University Hospital and Durham Regional Hospital, from January 1, 2005 to January 1, 2015 (n = 1,033). Results: Overall, there was no significant bivariate difference of 30 day readmission for CVD between Durham and Granville Counties for the 10 year period. However the results from the logistic regression models estimating the factors associated with 30-day readmission when area-level factors are held constant suggest that patients from Granville county are significantly more likely to be readmitted than patients from Durham county (OR=1.28; 95% CI, 1.15-1.43).

description: The selection of maskers and playback gain levels in a soundscape augmentation system is crucial to its effectiveness in improving the overall acoustic comfort of a given environment. Traditionally, the selection of appropriate maskers and gain levels has been informed by expert opinion, which may not representative of the target population, or by listening tests, which can be time-consuming and labour-intensive. Furthermore, the resulting static choices of masker and gain are often inflexible to the dynamic nature of real-world soundscapes. In this work, we utilized a deep learning model to perform joint selection of the optimal masker and its gain level for a given soundscape. The proposed model was designed with highly modular building blocks, allowing for an optimized inference process that can quickly search through a large number of masker and gain combinations. In addition, we introduced the use of feature-domain soundscape augmentation conditioned on the digital gain level, eliminating the computationally expensive waveform-domain mixing process during inference time, as well as the tedious pre-calibration process required for new maskers. The proposed system was validated on a large-scale dataset of subjective responses to augmented soundscapes with more than 440 participants, ensuring the ability of the model to predict combined effect of the masker and its gain level on the perceptual pleasantness level.

description: The geometric optics approximation provides an interpretation for eikonal correspondence that, in black-hole-containing spacetimes, connects high-frequency black hole quasinormal modes with closed photon orbits around said black hole. This correspondence has been identified explicitly for Schwarzschild, Reissner-Nordström, Kerr, and Kerr-Newman black holes, the violation of which can be a potential hint toward physics beyond General Relativity. Notably, the aforementioned black hole spacetimes have sufficient symmetries such that both the geodesic equations and the master wave equations are separable. The identification of the correspondence seems to largely rely on these symmetries. One naturally asks how the eikonal correspondence would appear if the spacetime were less symmetric. For a pioneering work in this direction, we consider in this paper a deformed Schwarzschild spacetime retaining only axisymmetry and stationarity. We show that up to the first order of spacetime deformations the eikonal correspondence manifests through the definition of the \textit{averaged} radius of trapped photon orbits along their one period. This averaged radius overlaps the potential peak in the master wave equation, which can be defined up to the first order of spacetime deformations, allowing the explicit identification of the eikonal correspondence.

description: Migrant and seasonal farmworkers (MSFW) play an important role in the agricultural and economic vitality of the United States. Given occupational hazards associated with agricultural labor and work, research involving the health of MSFW has been primarily related to the occupational and environmental health concerns. However, research is limited on broader health concerns affecting this population, including hypertension and cardiovascular health, and strategies to improve health outcomes among this population. Community health workers (CHWs) have been effectively utilized to create culturally appropriate and contextualized screening and educational programs for hypertension. This systematic review intended to understand the utility of community health workers to screen and implement culturally effective programs for Hispanic/ Latino farmworkers. Following the review and evaluation of 27 articles, this review found insufficient evidence that community-based or CHW-led educational or screening programs significantly improved long-term cardiovascular health outcomes despite limited improvement in heart healthy behaviors and knowledge. More research is necessary to understand what strategies are effective to improve cardiovascular outcomes among MSFW given their prevalence of hypertension and other cardiovascular disease (CVD) risk factors. Using demographic and clinical data collected by North Carolina Farmworkers Health Program (NCFHP), this additional descriptive study of NC farmworkers found the prevalence of hypertension, using actual blood pressure measurements, was 23.0% in 2012 and 25.6% in 2015. Additionally, 39.1% of all farmworkers with BMI data were overweight and 39.6% were obese in 2015. Further, compared to seasonal farmworkers, migrant farmworkers demonstrated nearly double odds of hypertension in 2012 and over 1.5 the odds of hypertension in 2015. This study deepened the understanding of the health challenges facing this already underserved population and emphasized the needed to find effective strategies to improve their health.
Characterization and modeling of crosstalk and afterpulsing in Hamamatsu silicon photomultipliers

description: The crosstalk and afterpulsing in Hamamatsu silicon photomultipliers, called Multi-Pixel Photon Counters (MPPCs), have been studied in depth. Several components of the correlated noise have been identified according to their different possible causes and their effects on the signal. In particular, we have distinguished between prompt and delayed crosstalk as well as between trap-assisted and hole-induced afterpulsing. The prompt crosstalk has been characterized through the pulse amplitude spectrum measured at dark conditions. The newest MPPC series, which incorporate isolating trenches between pixels, exhibit a very low prompt crosstalk, but a small component remains likely due to secondary photons reflected on the top surface of the device and photon-generated minority carriers diffusing in the silicon substrate. We present a meticulous procedure to characterize the afterpulsing and delayed crosstalk through the amplitude and delay time distributions of secondary pulses. Our results indicate that both noise components are due to minority carriers diffusing in the substrate and that this effect is drastically reduced in the new MPPC series as a consequence of an increase of one order of magnitude in the doping density of the substrate. Finally, we have developed a Monte Carlo simulation to study the different components of the afterpulsing and crosstalk. The simulation results support our interpretation of the experimental data. They also demonstrate that trenches longer than those employed in the Hamamatsu MPPCs would reduce the crosstalk to a much greater extent.

description: Quantum fields are considered as generators of infinite-dimensional Clifford algebra $Cl(\infty)$, which can be either orthogonal (in case of fermions) or symplectic (in case of bosons). A generic quantum state can be expressed as a superposition of the basis elements of $Cl(\infty)$, the superposition coefficients being multiparticle complex-valued wave functions. The basis elements, that are products of the generators of $Cl(\infty)$ in the Witt basis, act as creation and annihilation operators. They create positive and negative energy states that include the bare and the Dirac vacuum as special cases. It is shown that the nonvanishing electric charge arises from an extra dimension or from doubling the number of creation and annihilation operators, which brings an extra imaginary unit ${\bar i}$ into the description. A further extension is to consider the ${\bar i}$ as one of the quaternionic imaginary units and consider a generic state as having values in the quaternionic algebra or, equivalently, in the complexified 2-dimensional Clifford algebra, $Cl(2)\otimes C$.contains two distinct fundamental representations of $SU(2)$, one associated with the weak isospin oublet $(ν_e,e^-)$, and the other one with the doublet of new leptons, denoted $(ε^+,ν_ε)$, that together with the new quarks $(u',d')$ can be identified with dark matter.

Mechanism for the efficient homogeneous nucleation of ice in a weakly-ionized, ultra-cold plasma

description: It is proposed that the rapid observed homogeneous nucleation of ice dust in a cold, weakly-ionized plasma depends on the formation of hydroxide (OH$^-$) by fast electrons impacting water molecules. These OH$^{-}$ ions attract neutral water molecules because of the high dipole moment of the water molecules and so hydrates of the form (OH)$^{-}$(H$_{2}$O)$_{n}$ are formed. The hydrates continuously grow in the cold environment to become macroscopic ice grains. These ice grains are negatively charged as a result of electron impact and so continue to attract water molecules. Because hydroxide is a negative ion, unlike positive ions it does not suffer recombination loss from collision with plasma electrons. Recombination with positive ions is minimal because positive ions are few in number (weak ionization) and slow-moving as result of being in thermal equilibrium with the cold background gas.

description: We study disc galaxies in the framework of General Relativity to focus on the possibility that, even in the low energy limit, there are relevant corrections with respect to the purely Newtonian approach. Our analysis encompasses the model both considering a low energy expansion and exact solutions, making it clear the connection between these different approaches. In particular, we focus on two different limits: the well known gravitomagnetic analogy and a new limit, called strong gravitomagnetism, which has corrections in c of the same order as the Newtonian terms. We show that these two limits of the general class of solution can account for the observed flat velocity profile, contrary to what happens using Newtonian models, where a dark matter contribution is required. Hence, we suggest a geometrical origin for a certain amount of dark matter effects.

description: With the increasing popularity of food delivery platforms, it has become pertinent to look into the working conditions of the 'gig' workers in these platforms, especially providing them fair wages, reasonable working hours, and transparency on work availability. However, any solution to these problems must not degrade customer experience and be cost-effective to ensure that platforms are willing to adopt them. We propose WORK4FOOD, which provides income guarantees to delivery agents, while minimizing platform costs and ensuring customer satisfaction. WORK4FOOD ensures that the income guarantees are met in such a way that it does not lead to increased working hours or degrade environmental impact. To incorporate these objectives, WORK4FOOD balances supply and demand by controlling the number of agents in the system and providing dynamic payment guarantees to agents based on factors such as agent location, ratings, etc. We evaluate WORK4FOOD on a real-world dataset from a leading food delivery platform and establish its advantages over the state of the art in terms of the multi-dimensional objectives at hand.

Shift Work Sleep Disorder: Implications for the Occupational and Environmental Health Nurse
Creators: name: Mensing, Linda

Year: 2015

description: Approximately 20% of all workers in industrialized countries and 15 million Americans have work hours which overlap with the typical sleep period (United States [U.S.] Bureau of Labor Statistics, 2007). All shift workers are at risk for shift work sleep disorder (SWSD), a type of circadian rhythm sleep disorder (CRSD) characterized by excessive sleepiness and insomnia. Approximately 10% of shift workers meet the diagnostic criteria for SWSD (Schwartz & Roth, 2006). Although shift work schedules and sleep insufficiency negatively affect health, safety, and the quality of life of workers, SWSD remains an under-recognized and undertreated condition. SWSD has serious medical, psychological, social, and quality of life consequences for individual workers. It also affects organizations through increased health care costs, impaired job performance, and decreased productivity (Schwartz & Roth, 2006). Fatigue in workers is a public health concern since it has been linked to industrial accidents, medical errors, and traffic injuries and fatalities. The occupational and environmental health nurse (OEHN) plays a vital role in management of SWSD in the workplace using a comprehensive, interdisciplinary approach. Strategies such as adjusting work schedules, educating employees, families, supervisors, and managers about SWSD and adaptive strategies, and implementing early referral and treatment to affected workers may prevent or mitigate the negative consequences of SWSD.

description: We use observations of 66 reverberation-measured \Mgii\ quasars (QSOs) in the redshift range $0.36 \leq z \leq 1.686$ -- a subset of the 78 QSOs we previously studied that also have \rfe\ (flux ratio parameter of UV \Feii\ to \Mgii\ that is used as an accretion-rate proxy) measurements -- to simultaneously constrain cosmological model parameters and QSO 2-parameter and 3-parameter radius-luminosity ($R-L$) relation parameters in six different cosmological models. We find that these QSO $R-L$ relation parameters are independent of the assumed cosmological model and so these QSOs are standardizable through the $R-L$ relations. Also: (1) With the 2-parameter $R-L$ relation, we find that the low-\rfe\ and high-\rfe\ data subsets obey the same $R-L$ relation within the error bars. (2) Extending the 2-parameter $R-L$ relation to a 3-parameter one does not result in the hoped-for reduction in the intrinsic dispersion of the $R-L$ relation. (3) Neither of the 3-parameter $R-L$ relations provide a significantly better fit to the measurements than does the 2-parameter $R-L$ relation. These are promising results for the on-going development of \Mgii\ cosmological probes. The first and third of these results differ significantly from those we found elsewhere from analyses of reverberation-measured \hb\ QSOs.

description: Galaxy shapes are subject to distortions due to the tidal field of the Universe. The cross-correlation of galaxy lensing with the lensing of the Cosmic Microwave Background (CMB) cannot easily be separated from the cross-correlation of galaxy intrinsic shapes with CMB lensing. Previous work suggested that the intrinsic alignment contamination can be $15\%$ of this cross-spectrum for the CFHT Stripe 82 (CS82) and Atacama Cosmology Telescope surveys. Here we re-examine these estimates using up-to-date observational constraints of intrinsic alignments at a redshift more similar to that of CS82 galaxies. We find a $\approx$ $10\%$ contamination of the cross-spectrum from red galaxies, with $\approx$ $3\%$ uncertainty due to uncertainties in the redshift distribution of source galaxies and the modelling of the spectral energy distribution. Blue galaxies are consistent with being unaligned, but could contaminate the cross-spectrum by an additional $9.5\%$ within current $95\%$ confidence levels. While our fiducial estimate of alignment contamination is similar to previous work, our work suggests that the relevance of alignments for CMB lensing-galaxy lensing cross-correlation remains largely unconstrained. Little information is currently available about alignments at $z>1.2$. We consider the upper limiting case where all $z>1.2$ galaxies are aligned with the same strength as low redshift luminous red galaxies, finding as much as $\approx$ $60\%$ contamination.

description: In this paper, we provide a more accurate description of the evolution of the magnetic flux redistribution during prestellar core collapse by including resistive terms in the magnetohydrodynamics (MHD) equations. We focus more particularly on the impact of ambipolar diffusion. We use the adaptive mesh refinement code RAMSES to carry out such calculations. The resistivities required to calculate the ambipolar diffusion terms were computed using a reduced chemical network of charged, neutral and grain species. The inclusion of ambipolar diffusion leads to the formation of a magnetic diffusion barrier in the vicinity of the core, preventing accumulation of magnetic flux in and around the core and amplification of the field above 0.1G. The mass and radius of the first Larson core remain similar between ideal and non-ideal MHD models. This diffusion plateau has crucial consequences on magnetic braking processes, allowing the formation of disk structures. Magnetically supported outflows launched in ideal MHD models are weakened when using non-ideal MHD. Contrary to ideal MHD misalignment between the initial rotation axis and the magnetic field direction does not significantly affect the results for a given mu, showing that the physical dissipation truly dominate over numerical diffusion. We demonstrate severe limits of the ideal MHD formalism, which yield unphysical behaviours in the long-term evolution of the system. This includes counter rotation inside the outflow, interchange instabilities, and flux redistribution triggered by numerical diffusion, none observed in non-ideal MHD. Disks with Keplerian velocity profiles form in all our non-ideal MHD simulations, with final mass and size which depend on the initial magnetisation. This ranges from a few 0.01 solar masses and 20-30 au for the most magnetised case (mu=2) to 0.2 solar masses and 40-80 au for a lower magnetisation (mu=5).

description: We report the large polar magnetooptical Kerr effect in L10-MnxGa epitaxial films with giant perpendicular magnetic anisotropy in a wide composition range. The Kerr rotation was enhanced by a factor of up to 10 by decreasing Mn atomic concentration, which most likely arises from the variation of the effective spin-orbit coupling strength, compensation effect of magnetic moments at different Mn atom sites, and overall strain. The Kerr ellipticity and the magnitude of the complex Kerr angle is found to have more complex composition-dependence that varies with the photon energy. These L10-MnxGa films show large Kerr rotation of up to 0.10o, high reflectivity of 35%-55% in a wide wavelength range of 400~850 nm, and giant magnetic anisotropic field of up to 210 kOe, making them an interesting material system for emerging spintronics and terahertz modulator applications.

description: Background: The United States population is becoming increasingly diverse, with racial and ethnic minorities projected to represent ahnost half of the U.S. population by the year 2050. There is compelling evidence that racial and ethnic minorities have experienced health care disparities in the past. The United States government, along with other health care stakeholders, is increasing efforts to evaluate the etiology of these disparities and create interventions to address them. One important initiative to address health care disparities faced by racial and ethnic minorities is to improve cultural competency in order to help health care providers serve a diverse population. Muslims in America represent the fastest growing religious minority population. Given that religious data is not tracked by the Census, the exact numbers of Muslims living in America, or North Carolina in particular, cannot be obtained. Muslim American women may represent an especially vulnerable population given the double minority status they hold. Methods: Little research has been conducted on the health needs of Muslim American women. In order to examine the barriers Muslim women experience in obtaining culturally appropriate health care, a qualitative needs assessment was conducted with local Muslim women in the Raleigh/Durham area. Three focus groups were conducted in the span of two months. This data, which was collected at Duke University, provide the basis for a secondary analysis carried out here. Transcripts from the focus groups were reviewed and coded by independent reviewers. These coded data were then compared for similar themes. Results/Conclusions: The major themes can be divided into two categories: health and well-being concerns and priority services of an ideal health center. The majority of focus group discussion centered on health and well being concerns. The two focus groups of local Muslim women shared similar concerns. Many of the Muslim women felt uncomfortable with preconceived notions that they felt going into their health care encounters. Many participants felt that stressed Muslim women, especially since September 11, 2001, have difficulty finding appropriate services locally. Participants also stressed that factors shared by non-Muslims and Muslims alike, such as poverty and transportation issues, affected ability to access quality health care. Priority services that the focus group participants desired in a health center include: all-female staff; education of non-Muslim health care providers; staff with understanding of Muslim women; cultural sensitivity; comprehensive services; and childcare/ children's health care. In the discussion of these findings, this paper identifies future interventions and research the Muslim community has discussed in order to address these local health needs.
Reconstructing Non-Markovian Open Quantum Evolution From Multi-time Measurements

description: For a quantum system undergoing non-Markovian open quantum dynamics, we demonstrate a tomography algorithm based on multi-time measurements of the system, which reconstructs a minimal environment coupled to the system, such that the system plus environment undergoes unitary evolution and that the reduced dynamics of the system is identical to the observed dynamics of it. The reconstructed open quantum evolution model can be used to predict any future dynamics of the system when it is further assumed to be time-independent. We define the memory size and memory complexity for the non-Markovian open quantum dynamics which characterize the complexity of the reconstruction.

description: Highly transparent superconducting contacts to a topological insulator (TI) remain a persistent challenge on the route to engineer topological superconductivity. Recently, the higher-order TI WTe$_2$ was shown to turn superconducting when placed on palladium (Pd) bottom contacts, demonstrating a promising material system in pursuing this goal. Here, we report the diffusion of Pd into WTe$_2$ and the formation of superconducting PdTe$_x$ as the origin of observed superconductivity. We find an atomically sharp interface in vertical direction to the van der Waals layers between the diffusion crystal and its host crystal, forming state-of-the-art superconducting contacts to a TI. The diffusion is discovered to be non-uniform along the width of the WTe$_2$ crystal, with a greater extend along the edges compared to the bulk. The potential of this contacting method is highlighted in transport measurements on Josephson junctions by employing external superconducting leads.

description: We study the Quantum Brownian motion of a charged particle moving in a harmonic potential in the presence of an uniform external magnetic field and linearly coupled to an Ohmic bath through momentum variables. We analyse the growth of the mean square displacement of the particle in the classical high temperature domain and in the quantum low temperature domain dominated by zero point fluctuations. We also analyse the Position Response Function and the long time tails of various correlation functions. We notice some distinctive features, different from the usual case of a charged quantum Brownian particle in a magnetic field and linearly coupled to an Ohmic bath via position variables.

description: Measurement-based quantum computation is a model for quantum information processing utilizing local measurements on suitably entangled resource states for the implementation of quantum gates. A complete characterization for universal resource states is still missing. It has been shown that symmetry-protected topological order in one dimension can be exploited for the protection of certain quantum gates in measurement-based quantum computation. In this paper we show that the two-dimensional plaquette states on arbitrary lattices exhibit nontrivial symmetry-protected topological order in terms of symmetry fractionalization and that they are universal resource states for quantum computation. Our results of the nontrivial symmetry-protected topological order on arbitrary 2D lattices are based on an extension of the recent construction by Chen, Gu, Liu and Wen [Phys. Rev. B \textbf{87}, 155114 (2013)] on the square lattice.

description: In this paper we evaluate the performance of Unified Parallel C (which implements the partitioned global address space programming model) using a numerical method that is widely used in fluid dynamics. In order to evaluate the incremental approach to parallelization (which is possible with UPC) and its performance characteristics, we implement different levels of optimization of the UPC code and compare it with an MPI parallelization on four different clusters of the Austrian HPC infrastructure (LEO3, LEO3E, VSC2, VSC3) and on an Intel Xeon Phi. We find that UPC is significantly easier to develop in compared to MPI and that the performance achieved is comparable to MPI in most situations. The obtained results show worse performance (on VSC2), competitive performance (on LEO3, LEO3E and VSC3), and superior performance (on the Intel Xeon Phi).

description: Building performance has been shown to degrade significantly after commissioning, resulting in increased energy consumption and associated greenhouse gas emissions. Continuous Commissioning using existing sensor networks and IoT devices has the potential to minimize this waste by continually identifying system degradation and re-tuning control strategies to adapt to real building performance. Due to its significant contribution to greenhouse gas emissions, the performance of gas boiler systems for building heating is critical. A review of boiler performance studies has been used to develop a set of common faults and degraded performance conditions, which have been integrated into a MATLAB/Simulink emulator. This resulted in a labeled dataset with approximately 10,000 simulations of steady-state performance for each of 14 non-condensing boilers. The collected data is used for training and testing fault classification using K-nearest neighbour, Decision tree, Random Forest, and Support Vector Machines. The results show that the Support Vector Machines method gave the best prediction accuracy, consistently exceeding 90%, and generalization across multiple boilers is not possible due to low classification accuracy.
