description: Absolute transition frequencies of the $2s\; ^2{\rm S}_{1/2} \rightarrow 2p\;^2\mathrm{P}_{1/2,3/2}$ transitions in Be$^+$ were measured for the isotopes $^{7,9-12}$Be. The fine structure splitting of the $2p$ state and its isotope dependence are extracted and compared to results of \textit{ab initio} calculations using explicitly correlated basis functions, including relativistic and quantum electrodynamics effects at the order of $m α^6$ and $m α^7 \ln α$. Accuracy has been improved in both the theory and experiment by 2 orders of magnitude, and good agreement is observed. This represents one of the most accurate tests of quantum electrodynamics for many-electron systems, being insensitive to nuclear uncertainties.

Requiring adolescent informed assent in clinical research trials
Creators: name: Gustofson, Lisa-Marie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: For many years, the process of voluntary informed consent for adult clinical research subjects has been widely accepted, standardized, and federally regulated. In comparison, adolescent clinical research subjects were not afforded the same privileges. Within the past decade there has been an increase in the number of pediatric and adolescent clinical research trials in the United States (NCCF 2000). Consequently, the moral and ethical implications of clinical research on minors has become a widely discussed issue and the notion of adolescent assent- a minor's affirmative agreement to participate in a clinical research trial- has been recognized. The purpose of this paper is to discuss the current and future use of adolescent assent in clinical research trials.

description: Deep spectral-line surveys in the mm and sub-mm range can detect thousands of lines per band uncovering the rich chemistry of molecular clouds, star forming regions and circumstellar envelopes, among others objects. The ability to study the faintest features of spectroscopic observation is, nevertheless, limited by a number of factors. The most important are the source complexity (line density), limited spectral resolution and insufficient sideband (image) rejection (SRR). Dual Sideband (2SB) millimeter receivers separate upper and lower sideband rejecting the unwanted image by about 15 dB, but they are difficult to build and, until now, only feasible up to about 500 GHz (equivalent to ALMA Band 8). For example ALMA Bands 9 (602-720 GHz) and 10 (787-950 GHz) are currently DSB receivers. Aims: This article reports the implementation of an ALMA Band 9 2SB prototype receiver that makes use of a new technique called calibrated digital sideband separation. The new method promises to ease the manufacturing of 2SB receivers, dramatically increase sideband rejection and allow 2SB instruments at the high frequencies currently covered only by Double Sideband (DSB) or bolometric detectors. Methods: We made use of a Field Programmable Gate Array (FPGA) and fast Analog to Digital Converters (ADCs) to measure and calibrate the receiver's front end phase and amplitude imbalances to achieve sideband separation beyond the possibilities of purely analog receivers. The technique could in principle allow the operation of 2SB receivers even when only imbalanced front ends can be built, particularly at very high frequencies. Results: This digital 2SB receiver shows an average sideband rejection of 45.9 dB while small portions of the band drop below 40 dB. The performance is 27 dB (a factor of 500) better than the average performance of the proof-of-concept Band 9 purely-analog 2SB prototype receiver.

description: Two-dimensional (2D) materials for their versatile band structures and strictly 2D nature have attracted considerable attention over the past decade. Graphene is a robust material for spintronics owing to its weak spin-orbit and hyperfine interactions, while monolayer transition metal dichalcogenides (TMDs) possess a Zeeman effect-like band splitting in which the spin and valley degrees of freedom are nondegenerate. The surface states of topological insulators (TIs) exhibit a spin-momentum locking that opens up the possibility of controlling the spin degree of freedom in the absence of an external magnetic field. Nanostructures made of these materials are also viable for use in quantum computing applications involving the superposition and entanglement of individual charge and spin quanta. In this article, we review a selection of transport studies addressing the confinement and manipulation of charges in nanostructures fabricated from various 2D materials. We supply the entry-level knowledge for this field by first introducing the fundamental properties of 2D bulk materials followed by the theoretical background relevant to the physics of nanostructures. Subsequently, a historical review of experimental development in this field is presented, from the early demonstration of graphene nanodevices on SiO2 substrate to more recent progress in utilizing hexagonal boron nitride to reduce substrate disorder. In the second part of this article, we extend our discussion to TMDs and TI nanostructures. We aim to outline the current challenges and suggest how future work will be geared towards developing spin qubits in 2D materials.

description: Since the publication of the Institute of Medicine report The Future of Public Health in 1988, much of the effort to improve the public health infrastructure in the United States has focused on improving the knowledge, skills and abilities (KSA's) of the public health workforce. The first step in workforce development has been to define the competencies or KSA's needed by public health workers. Competencies have been defined in three categories: basic knowledge of public health: core competencies; and technical, or discipline-specific competencies. The next step is to develop curricula to address the gap between KSA's needed and the KSA's required by public health workers. The environmental health segment of the workforce has been included in public health workforce development efforts. The Public Health Faculty/Agency Forum, the National Environmental Health Association, the Centers for Disease Control and Prevention, and others have defined the competencies needed by this discipline. Development efforts for this segment of the public health workforce face unique challenges: environmental health practitioners be employed by a variety of public agencies and current environmental health practitioners enter the profession with a variety of academic backgrounds. For the most part, these sets of competencies reflect expert opinion with little review and input from state and local practitioners. However, state and local agencies can use these competencies as a framework for improving the education and training of their environmental health practitioners, building on initial efforts that encompass the general public health workforce.

Children’s Exposure to Food Dyes at School: Time for a Policy Change
Creators: name: Braasch, Erin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Artificial food colors (AFCs) have become ubiquitous in the standard American diet. Average intake of AFCs has increased 5-fold in the past 20 years. Mounting evidence links the consumption of AFCs to symptoms of hyperactivity and inattention in children both with and without known, previous hyperactivity. Additionally, food dyes deceive consumers into thinking foods are higher in nutritional content than they really are, making it more difficult to follow current dietary recommendations. Both of these factors are relevant to the school environment. Hyperactivity and inattention in early elementary grades are known to predict poor academic outcomes by adolescence. Children meeting dietary guidelines for nutrition are better equipped to learn. By establishing policies that reduce children’s exposure to AFCs at school, school officials may reduce the amount and degree of hyperactivity and inattentiveness in the classrooms and more easily support children in consuming a healthy diet. The development and implementation of local, school policies to eliminate food rewards and remove food from celebrations presents the most viable policy option for reducing AFC consumption in schools. Public health can support local school policy by developing interventions within the three core functions of public health: assessment, policy development, and assurance.

description: In this paper, we propose a novel and efficient two-stage variable selection approach for sparse GLARMA models, which are pervasive for modeling discrete-valued time series. Our approach consists in iteratively combining the estimation of the autoregressive moving average (ARMA) coefficients of GLARMA models with regularized methods designed for performing variable selection in regression coefficients of Generalized Linear Models (GLM). We first establish the consistency of the ARMA part coefficient estimators in a specific case. Then, we explain how to efficiently implement our approach. Finally, we assess the performance of our methodology using synthetic data, compare it with alternative methods and illustrate it on an example of real-world application. Our approach, which is implemented in the GlarmaVarSel R package and available on the CRAN, is very attractive since it benefits from a low computational load and is able to outperform the other methods in terms of coefficient estimation, particularly in recovering the non null regression coefficients.

description: We investigate the continuum emission of viscous decretion discs around Be stars in this paper. The results obtained from non-LTE (local thermodynamic equilibrium) radiative transfer models show two regimes in the disc surface brightness profile: an inner optically thick region, which behaves as a pseudo-photosphere with a wavelength-dependent size, and an optically thin tenuous outer part, which contributes with about a third of the total flux. The isophotal shape of the surface brightness is well described by elliptical contours with an axial ratio $b/a=\cos i$ for inclinations $i<75^{\circ}$. Based on these properties, a semi-analytical model was developed to describe the continuum emission of gaseous discs. It provides fluxes and spectral slopes at the infrared within an accuracy of $10\%$ and $5\%$, respectively, when compared to the numerical results. The model indicates that the infrared spectral slope is mainly determined by both the density radial slope and the disc flaring exponent, being practically independent of disc inclination and base density. As a first application, the density structure of 15 Be stars was investigated, based on the infrared flux excess, and the results compared to previous determinations in the literature. Our results indicate that the decretion rates are in the range of $10^{-12}$ to $10^{-9}\,{\rm M_{\odot}\,yr^{-1}}$, which is at least two orders of magnitude smaller than the previous outflowing disc model predictions.

description: We put forward a model that describes a decaying and evanescent point source of non-interacting quantum waves in 1D. This point-source assumption allows for a simple description that captures the essential aspects of the dynamics of a wave traveling through a classically forbidden region without the need to specify the details of the inner region. The dynamics of the resulting wave is examined and several characteristic times are identified. One of them generalizes the tunneling time-scale introduced by Büttiker and Landauer and it characterizes the arrival of the maximum of the wave function. Diffraction in time and deviations from exponential decay are also studied. Here we show that there exists an optimal injection frequency and detection point for the observation of these two quantum phenomena.

Comprehensive lifestyle intervention counseling effect on weight loss and quality of life in individuals in the primary care setting with BMI > 25 kg/m2.
Creators: name: Patel, Jaynil
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: Finding successful prevention, treatment, and management strategies for obesity continues to be evasive in most primary care practices even with the availability of various guidelines from organizations such as the American Heart Association (AHA), The Obesity Society (TOS), and The American College of Cardiology (ACC). The dominant approach to initial overweight and obesity management is comprehensive lifestyle intervention counseling. The purpose of this quality improvement project (QI) is to evaluate comprehensive lifestyle intervention counseling focus groups and their effect on body mass index (BMI) and quality of life (QOL). Obesity is an issue causing significant morbidity and mortality. Focus groups have been shown to encourage behavioral changes required to reduce weight. Healthful weight loss has been shown to improve quality of life and reduce direct health care costs. Methodology: Eight participants with an BMI > 25 kg/m2 were selected to participate in focus groups with attention to comprehensive lifestyle interventions for four, 45-minute weekly sessions. Data measures were BMI and the 26 question World Health Organization (WHO) QOL survey questionnaire used to measure the effectiveness of the intervention at the first and last focus group session. Results: Wilcoxon Signed-Ranks Test indicated that post-test ranks were statistically significantly higher than the pre-test ranks. Post BMI P < 0.35. Post Survey P < 0.12. Implications for Practice: Results of this project indicate group-based counseling is an effective resource to help combat obesity in the primary care setting. More research needs to be conducted for internet-based group counseling approaches and other counseling delivery method effectiveness.

description: While machine learning and ranking-based systems are in widespread use for sensitive decision-making processes (e.g., determining job candidates, assigning credit scores), they are rife with concerns over unintended biases in their outcomes, which makes algorithmic fairness (e.g., demographic parity, equal opportunity) an objective of interest. 'Algorithmic recourse' offers feasible recovery actions to change unwanted outcomes through the modification of attributes. We introduce the notion of ranked group-level recourse fairness, and develop a 'recourse-aware ranking' solution that satisfies ranked recourse fairness constraints while minimizing the cost of suggested modifications. Our solution suggests interventions that can reorder the ranked list of database records and mitigate group-level unfairness; specifically, disproportionate representation of sub-groups and recourse cost imbalance. This re-ranking identifies the minimum modifications to data points, with these attribute modifications weighted according to their ease of recourse. We then present an efficient block-based extension that enables re-ranking at any granularity (e.g., multiple brackets of bank loan interest rates, multiple pages of search engine results). Evaluation on real datasets shows that, while existing methods may even exacerbate recourse unfairness, our solution -- RAGUEL -- significantly improves recourse-aware fairness. RAGUEL outperforms alternatives at improving recourse fairness, through a combined process of counterfactual generation and re-ranking, whilst remaining efficient for large-scale datasets.

description: Quantum coherence is a fundamental common trait of quantum phenomena, from the interference of matter waves to quantum degeneracy of identical particles. Despite its importance, estimating and measuring quantum coherence in generic, mixed many-body quantum states remains a formidable challenge, with fundamental implications in areas as broad as quantum condensed matter, quantum information, quantum metrology and quantum biology. Here we provide a quantitative definition of the variance of quantum coherent fluctuations (the quantum variance) of any observable on generic quantum states. The quantum variance generalizes the concept of thermal de Broglie wavelength (for the position of a free quantum particle) to the space of eigenvalues of any observable, quantifying the degree of coherent delocalization in that space. The quantum variance is generically measurable and computable as the difference between the static fluctuations and the static susceptibility of the observable; despite its simplicity, it is found to provide a tight lower bound to most widely accepted estimators of "quantumness" of observables (both as a feature as well as a resource), such as the Wigner-Yanase skew information and the quantum Fisher information. When considering bipartite fluctuations in an extended quantum system, the quantum variance expresses genuine quantum correlations (of discord type) among the two parts. In the case of many-body systems it is found to obey an area law at finite temperature, extending therefore area laws of entanglement and quantum fluctuations of pure states to the mixed-state context. Hence the quantum variance paves the way to the measurement of macroscopic quantum coherence and quantum correlations in most complex quantum systems.

description: Abstract: Objectives: We evaluated whether carotid intima-media thickness (CIMT) and the presence or absence of plaque improved coronary heart disease (CHD) risk prediction when added to traditional risk factors. Background: Traditional cardiovascular disease (CVD) risk prediction schemes need further improvement as the majority of the CVD events occur in the intermediate risk groups. On an ultrasound scan, CIMT and presence of plaque are associated with CVD, and therefore could potentially help improve CHD risk prediction. Methods: Risk prediction models (overall, and in men and women) considered included traditional risk factors (TRF) only, TRF plus CIMT, TRF plus plaque, and TRF plus CIMT plus plaque presence. Predictivity was established by calculating the area under the curve (AUC). Cox proportional hazards models were used to estimate 10-year CHD risk for each risk model. Observed events were compared with expected events, and, the net reclassification index (NRI) was calculated. Results: Overall, the CIMT plus TRF plus plaque model provided the most improvement in AUC in the overall sample. Similarly, the CIMT plus TRF plus plaque model had the best net reclassification index of 9.9% in the overall population. However, comparison of TRF and CIMT and plaque with TRF and CIMT or TRF and plaque only resulted in statistically non-significant changes of the statistical test. Conclusions: Adding plaque and CIMT to TRF improve CHD risk prediction in the Jackson Heart Study (JHS). We hope that our study will shed further light on which patients to identify for further risk factor modification and or medical treatment and further intervention to reduce the burden of cardiovascular disease, and its overall impact in our population.

description: In the present paper we investigate the Tonks-Girardeau gas confined in a harmonic trap at finite temperature with thermal Bose-Fermi mapping method. The pair distribution, density distribution, reduced one-body density matrix, the occupations number of natural orbitals, and momentum distribution are evaluated. In the whole temperature regime the pair distribution and density distribution exhibit the same properties as those of polarized free Fermions because both of them depend on the modulus of wavefunction rather than wavefunction. While the reduced one-body density matrix, the natural orbital occupation, momentum distribution, which depend on wavefunction, of Tonks gas displays Bose properties different from polarized free Fermions at low temperature. At high temperature we can not distinguish Tonks gas from the polarized free Fermi gas by all properties qualitatively.

description: Multiplicity distributions $P(N)$ measured in multiparticle production processes are most frequently described by the Negative Binomial Distribution (NBD). However, with increasing collision energy some systematic discrepancies become more and more apparent. They are usually attributed to the possible multi-source structure of the production process and described using a multi-NBD form of the multiplicity distribution. We investigate the possibility of keeping a single NBD but with its parameters depending on the multiplicity $N$. This is done by modifying the widely known clan model of particle production leading to the NBD form of $P(N)$. This is then confronted with the approach based on the so-called cascade-stochastic formalism which is based on different types of recurrence relations defining $P(N)$. We demonstrate that a combination of both approaches allows the retrieval of additional valuable information from the multiplicity distributions, namely the oscillatory behavior of the counting statistics apparently visible in the high energy data.

description: There are approximately three million youths under the age of 18 in the United States (U.S.) labor force annually who have sustained a considerable number of preventable work related fatalities and injuries (Runyan, Bowling, Schulman, Gallagher, 2005). Research regarding youth fatalities and injuries consisted of a literature review done through the University of North Carolina Health Sciences Library database, Internet search through Google, as well as informal observations of youth workers in various settings. Future research is imperative in light of the gaps in the literature about best practices to prevent occupational fatalities, illnesses, and injuries for youths, who are often confusingly referred to interchangeably as children, adolescents, or teen workers in the various studies. Major points of the literature review include, but are not limited to the following findings; youth workers have unique characteristics which make them especially vulnerable to health hazards on the job; current federal and state mandates are often outdated and poorly enforced; there is a paucity of research on the subject of best practices for prevention of occupational hazards for youth; and training can be improved by tailoring materials according to a youth's specific age, developmental level, cultural viewpoints, and individual style of learning. Despite attempts to protect this population, the National Institute for Occupational Safety and Health (NIOSH) reports that approximately 100,000 youths annually seek treatment in an emergency room for a work-related injury, and that at least 70 die from their work (2005a). The time has arrived to standardize the definition of youths to minimize confusion about who they are; establish a governmental agency specifically accountable for the protection of all youths working the U.S.; upgrade federal and state laws as well as safety regulations for this population; improve the quality of the research; apply the research findings of best practices to real world settings; improve fatality, illness, and injury surveillance techniques for all youth workers; improve existing educational and training programs; and empower youths and their guardians to exercise their rights. Occupational and environmental health nurses are perfectly poised to make a significant impact on this target population once they become more educated about and inspired by these quiet and steadfast workers.

description: Objective: To describe the relationship between the location of Pediatric Intensive Care Unit (PICU) facilities and county-level child mortality in the USA. Design: Cross-sectional ecologic study. Setting: 3110 counties in the contiguous USA. Pediatric Care Area (PCA) was specified as counties within a 60-mile radius of the geographic center of a county with PICU facilities. Interventions: None Measurements and main results: In 1997, PICU facilities were present in 9% of USA counties and were predominantly urban (98%) in location. Over half (58%) of USA counties were included in PCAs. There were 96,413 deaths of children 0- 14 years during the study period from 1996 to 1998. In bivariate analyses, residence within a PCA was related to lower mortality from trauma (incidence rate ratio [IRR] = 0.85, 95% confidence interval [CI] 0.83-0.87) and congenital anomalies (IRR= 0.98, 95% CI: 0.97-0.99). Controlling for residence in rural counties, poverty, and presence of pediatric intensivists, residence in a PCA remained associated with lower mortality from trauma (IRR= 0.87, 95% CI 0.85- 0.89) and congenital anomalies (IRR = 0.97, 95% CI 0.96-0.99) compared to residence outside a PCA. Mortality from conditions of perinatal origin, infectious diseases, and benign neoplasms was higher in counties within PCAs compared to those outside PCAs. Conclusion: Proximity to PICU facilities is associated with significant differences in child mortality particular to specific causes at the county level. These associations have implications for the establishment of PICU facilities, and warrant further study at the level of the individual patient.

description: We find the exact size of a maximal non-commuting set in unipotent uppertriangular linear group $UU_4(\mathbb{F}_q)$ in terms of a non-commuting geometric structure (Refer Definition [10]), where $\mathbb{F}_q$ is the finite field with $q$ elements. Then we get bounds on the size of such a set by explicitly finding certain non-commuting sets in the non-commuting structure.
