description: Interpretation of the oscillation spectrum of the slowly pulsating B-type star HD21071 is presented. We show that non-rotating models cannot account for the two highest amplitude frequencies and taking into account the effects of rotation is necessary. Rotating seismic models are constructed using various chemical compositions, opacity data, core overshooting parameters and rotational velocities. There are prospects for seismic modelling of SPB stars, even if no asymptotic pattern is observed in their oscillation spectra, provided an unambiguous mode identification is doable and the effects of rotation are properly included.

Engaging Men in Eliminating Mother to Child Transmission (EMTCT) of HIV in Sub-Saharan Africa
Creators: name: Ekpe, Chigozie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Mother-to-child transmission of HIV (MTCT) and maternal mortality, have garnered increased global attention and are eliciting implementation of necessary interventions. Each day there are new cases of HIV among children globally, with the highest incident rates occurring in Sub-Saharan Africa. Prevention of mother-to-child transmission of HIV (PMTCT) is a practical intervention that averts transmission from mother to offspring. The United Nations and other partners are dedicated to eliminating new cases of HIV infections among the target populations. In the bid to prevent MTCT in the Sub-Saharan African region, women face certain gender-based obstacles. It is evident that men have a key role to play if MTCT is going to be an issue of the past. Low male participation in interventions that improve the health of their partners and children is linked to cultural, health systems, and socioeconomic barriers. Increased male involvement in HIV prevention and treatment efforts for both mother and child can lead to a decline in HIV transmission rates as well as improved health outcomes for families and the society in general. Total elimination of MTCT will require the complete support of male partners in various interventions. "If we are truly interested in creating a broad-based global response to the elimination of paediatric HIV, we cannot exclude half the population. We must rally men to the cause and demonstrate the benefits of gender equality, shared decision-making, partnership and non-violence - to themselves and their families. (Hence,) efforts must be taken to secure the involvement and support of men in all aspects of and to address HIV-and gender-related discrimination that impedes service access and uptake as well as client retention".

description: Tidal streams of globular clusters are ideal tracers of the Galactic gravitational potential. Compared to the few known, complex and diffuse dwarf-galaxy streams, they are kinematically cold, have thin morphologies and are abundant in the halo of the Milky Way. Their coldness and thinness in combination with potential epicyclic substructure in the vicinity of the stream progenitor turns them into high-precision scales. With the example of Palomar 5, we demonstrate how modeling of a globular cluster stream allows us to simultaneously measure the properties of the disrupting globular cluster, its orbital motion, and the gravitational potential of the Milky Way.

Sequential feedback scheme outperforms the parallel scheme for Hamiltonian parameter estimation

Subjects: subject: Quantum Physics (quant-ph)

description: Measurement and estimation of parameters are essential for science and engineering, where the main quest is to find out the highest achievable precision with given resources and design schemes to attain it. Two schemes, the sequential feedback scheme and the parallel scheme, are usually studied in quantum parameter estimation. While the sequential feedback scheme represents the most general scheme, it remains unknown whether it can outperform the parallel scheme for any quantum estimation tasks. In this Letter we show that the sequential feedback scheme has a 3-fold improvement over the parallel scheme for Hamiltonian parameter estimations on 2-dimensional systems, and an order of $O(d+1)$ improvement for Hamiltonian parameter estimation on $d-$dimensional systems. We also show that, contrary to the conventional belief, it is possible to simultaneously achieve the highest precision for estimating all three components of a magnetic field, which sets a benchmark on the local precision limit for the estimation of a magnetic field.

description: A key property of many-body localization, the localization of quantum particles in systems with both quenched disorder and interactions, is the area law entanglement of even highly excited eigenstates of many-body localized Hamiltonians. Matrix Product States (MPS) can be used to efficiently represent low entanglement (area law) wave functions in one dimension. An important application of MPS is the widely used Density Matrix Renormalization Group (DMRG) algorithm for finding ground states of one dimensional Hamiltonians. Here, we describe two algorithms, the Shift and Invert MPS (SIMPS) and excited state DMRG which finds highly-excited eigenstates of many-body localized Hamiltonians. Excited state DMRG uses a modified sweeping procedure to identify eigenstates whereas SIMPS is a shift-inverse procedure that applies the inverse of the shifted Hamiltonian to a MPS multiple times to project out the targeted eigenstate. To demonstrate the power of these methods we verify the breakdown of the Eigenstate Thermalization Hypothesis (ETH) in the many-body localized phase of the random field Heisenberg model, show the saturation of entanglement in the MBL phase and generate local excitations.

Dual Use Research of Concern: Balancing the Risks and Rewards of Current and Future Life Sciences Research
Creators: name: Howard, Deborah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: In 2011, two studies funded by the National Institutes of Health (NIH) which demonstrated the transmissibility of H5N1 (avian influenza) to mammals caused an uproar in the scientific community. Researchers engineered H5N1 viruses to make them transmissible by respiratory droplets between ferrets, an animal commonly used to model human influenza infection. These studies provided critical information to scientists and public health officials by demonstrating that H5N1 viruses can be mutated to enable them to spread among certain mammals perhaps even among humans. The generation of these strains raised safety and security concerns centered on whether the strains could be released accidently or used for malevolent purposes that could threaten public health or national security. These experiments triggered a global discussion for five months regarding the benefits and risks of funding, conducting research, and publishing these types of studies. As a result, the influenza community initiated a voluntary moratorium for 60 days that actually lasted over a year while the U.S. National Science Advisory Board for Biosecurity (NSABB) restricted publication of the results. As a direct outcome of the H5N1 experiments, the Dual Use Research of Concern Policy was released in March 2012 in an attempt to oversee this type of research. The dual use policy is not intended to restrict science but to support public health and national security. However, if the only country moving forward with a dual use policy is the U.S., then it will inhibit research while other countries make cutting edge discoveries in life sciences. The policy demonstrates the need for achieving consistency within the life science field of research throughout the globe. Fostering transparency at an institution leading up to the publication of research results will protect public health and the institution.

description: Let $μ$ be a probability measure with an infinite compact support on $\mathbb{R}$. Let us further assume that $(F_n)_{n=1}^\infty$ is a sequence of orthogonal polynomials for $μ$ where $(f_n)_{n=1}^\infty$ is a sequence of nonlinear polynomials and $F_n:=f_n\circ\dots\circ f_1$ for all $n\in\mathbb{N}$. We prove that if there is an $s_0\in\mathbb{N}$ such that $0$ is a root of $f_n^\prime$ for each $n>s_0$ then the distance between any two zeros of an orthogonal polynomial for $μ$ of a given degree greater than $1$ has a lower bound in terms of the distance between the set of critical points and the set of zeros of some $F_k$. Using this, we find sharp bounds from below and above for the infimum of distances between the consecutive zeros of orthogonal polynomials for singular continuous measures.

Sun-Like Magnetic Cycles in the Rapidly-Rotating Young Solar Analog HD 30495

description: A growing body of evidence suggests that multiple dynamo mechanisms can drive magnetic variability on different timescales, not only in the Sun but also in other stars. Many solar activity proxies exhibit a quasi-biennial ($\sim$2 year) variation, which is superimposed upon the dominant 11 year cycle. A well-characterized stellar sample suggests at least two different relationships between rotation period and cycle period, with some stars exhibiting long and short cycles simultaneously. Within this sample, the solar cycle periods are typical of a more rapidly rotating star, implying that the Sun might be in a transitional state or that it has an unusual evolutionary history. In this work, we present new and archival observations of dual magnetic cycles in the young solar analog HD 30495, an $\sim$1 Gyr-old G1.5V star with a rotation period near 11 days. This star falls squarely on the relationships established by the broader stellar sample, with short-period variations at $\sim$1.7 years and a long cycle of $\sim$12 years. We measure three individual long-period cycles and find durations ranging from 9.6-15.5 years. We find the short-term variability to be intermittent, but present throughout the majority of the time series, though its occurrence and amplitude are uncorrelated with the longer cycle. These essentially solar-like variations occur in a Sun-like star with more rapid rotation, though surface differential rotation measurements leave open the possibility of a solar equivalence.

description: Polyak proved that the set $\{\Omega1a,\Omega1b,\Omega2a,\Omega3a\}$ is a minimal generating set of oriented Reidemeister moves. One may distinguish between forward and backward moves, obtaining $32$ different types of moves, which we call directed oriented Reidemeister moves. In this article we prove that the set of $8$ directed Polyak moves $\{ Ω{1a}^\uparrow, Ω{1a}^\downarrow, Ω{1b}^\uparrow, Ω{1b}^\downarrow, Ω{2a}^\uparrow, Ω{2a}^\downarrow, Ω{3a}^\uparrow, Ω{3a}^\downarrow \}$ is a minimal generating set of directed oriented Reidemeister moves. We also specialize the problem, introducing the notion of a $L$-generating set for a link $L$. The same set is proven to be a minimal $L$-generating set for any link $L$ with at least $2$ components. Finally, we discuss knot diagram invariants arising in the study of $K$-generating sets for an arbitrary knot $K$, emphasizing the distinction between ascending and descending moves of type $\Omega3$.

description: The ${\mathcal D}$-pseudo-boson formalism is illustrated with two examples. The first one involves deformed complex Hermite polynomials built using finite-dimensional irreducible representations of the group ${\rm GL}(2,{\mathbb C})$ of invertible $2 \times 2$ matrices with complex entries. It reveals interesting aspects of these representations. The second example is based on a pseudo-bosonic generalization of operator-valued functions of a complex variable which resolves the identity. We show that such a generalization allows one to obtain a quantum pseudo-bosonic version of the complex plane viewed as the canonical phase space and to understand functions of the pseudo-bosonic operators as the quantized versions of functions of a complex variable.

Clot Warriors: Using Medical Students for Improved HA-VTE Prophylaxis
Creators: name: Nagle, Max
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Introduction: Health care-associated venous thromboembolism (HA-VTE) leads to significant costs, morbidity, and mortality. Health care systems can prevent these patient safety events using prophylactic methods and systems of care. Medical students could help identify patients requiring HA-VTE prophylaxis on the wards. This paper expounds a research study design for a patient safety educational intervention involving medical students in this role.Methods: We will give third-year medical students on inpatient medicine rotations a card to carry in their white coats to help remind them of VTE risk stratification, prophylaxis choice, and words to use with superiors when safety issues arise. This will be incorporated into a series of lectures given during the rotation, covering topics such as VTE prophylaxis, patient safety, systems thinking, and navigating hierarchies. Medical students will bring their knowledge and their cards onto the wards, enabling them to raise patient safety concerns regarding VTE prophylaxis to their teams. Students will then submit descriptions of the “near miss” events. We will also assess changes among medical students in attitude and self-reported knowledge through the Attitudes to Patient Safety Questionnaire.Discussion: The literature that ties medical student patient safety educational interventions to outcomes involving patient benefit is lacking. This study involves a simple design in an attempt to measure patient-related outcomes and student attitudes and self-reported knowledge. The study is feasible based on discussions and a trial with medical students. Limitations to the study include lacking connection to a patient health outcome along with under-emphasis of potential harms of VTE prophylaxis.

HD 155233b has a period of 885$\pm$63 days, eccentricity e=0.03$\pm$0.20, and m sin i=2.0$\pm$0.5 M_jup. The stellar-mass companions range in m sin i from 0.066 M_sun to 0.33 M_sun. Whilst HD 104358B falls slightly below the traditional 0.08 M_sun hydrogen-burning mass limit, and is hence a brown dwarf candidate, we estimate only a 50% a priori probability of a truly substellar mass.

Preventing Teen Pregnancy: Recommendations for a Comprehensive School Based Intervention
Creators: name: Davis, Diane
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Teen pregnancy is a prevalent problem in the US as well as locally. The United States has the highest rate of teen pregnancy in the developed world, and rates in our county are higher than both state and national rates. Teen pregnancy is costly for the teen, her child, and society. A review of international and national trends and interventions reveals that there are some proven methods which can decrease teen pregnancy by delaying onset of intercourse and increasing the use of condoms and contraception. Evidence shows that a well structured Comprehensive Sexual Education curriculum coupled with additional support for at risk teens; a program tailored to the local population but based on proven methods, is the most successful approach. Currently, the public school system in Durham County has no organized approach to this serious problem. Sexual education in our school systems is fractured and taught by teachers with varying levels of education and experience with no standardized training or curriculum. A revision of the current policies to include a standardized curriculum taught by well trained teachers and combined with additional support for at risk teens would provide our teens with the ability to make responsible sexual decisions, reducing teen pregnancy and its associated costs.
Generalized Hofmann quantum process fidelity bounds for quantum filters

Year: 2015
Subjects: subject: Quantum Physics (quant-ph)

description: We propose and investigate bounds on quantum process fidelity of quantum filters, i.e. probabilistic quantum operations represented by a single Kraus operator K. These bounds generalize the Hofmann bounds on quantum process fidelity of unitary operations [H.F. Hofmann, Phys. Rev. Lett. 94, 160504 (2005)], and are based on probing the quantum filter by pure states forming two mutually unbiased bases. Determination of these bounds therefore requires much less measurements than full quantum process tomography. We find that it is particularly suitable to construct one of the probe basis from the right eigenstates of K, because in this case the bounds are tight in the sense that if the actual filter coincides with the ideal one then both the lower and upper bounds are equal to one. We theoretically investigate application of these bounds to a two-qubit optical quantum filter formed by interference of two photons on a partially polarizing beam splitter. For experimentally convenient choice of factorized input states and measurements we study the tightness of the bounds. We show that more stringent bounds can be obtained by more sophisticated processing of the data using convex optimization and we compare our methods for different choice of the input probe states.

Evaluation of a Multi-Faceted Family Planning Intervention in an Indigenous Village in Rural Ecuador
Creators: name: Smith, Patrick Carlsen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: This master's paper describes a research project designed to evaluate a program that sought to educate rural Ecuadorians of indigenous origin and increase their use of family planning methods. Using survey methodology, the research compares utilization of family planning methods in a rural indigenous Ecuadorian village exposed to a multi-faceted family planning intervention versus villages not exposed to the intervention. This master's paper satisfies the requirements of the Master's of Public Health in the Health Leadership Program at the University of North Carolina at Chapel Hill by describing a research design complete to the data collection phase including construction of a new follow-up survey to be used as a data collection instrument, plans to improve the measurement instrument, and methods of analysis. The author describes the need for family planning, reviews the current literature, discusses the design of the research study, and outlines the proposed manuscript to be submitted for publication.

Program Planning for Primary Prevention of Child Maltreatment in Wake County
Creators: name: Hansen, Patricia

Year: 2005

description: Children have been mistreated throughout history. Parents and caregivers have committed a host of unspeakable acts against them, including murder, sexual exploitation, forced labor, abandonment and many other forms of brutality. Although such horrors are reprehensible by today's standards, and punishable by law, child maltreatment still exists and often goes undetected. Extensive research, in the last twenty-five years, has revealed many of the predisposing factors associated with child maltreatment and many programs have been implemented nationwide in an effort to prevent maltreatment from occurring. This paper describes a program planning process to develop an evidence-based primary prevention child maltreatment program in Wake County, the second most populous state in North Carolina. Wake County is fortunate to have a number family support programs, including some that serve families after child maltreatment has occurred, but none that are designed to prevent maltreatment. The proposed program will provide community capacity to address child maltreatment before it occurs.

description: Performing a systematic Bogoliubov-de Gennes spectral analysis, we illustrate that stationary vortex lines, vortex rings and more exotic states, such as hopfions, are robust in three-dimensional atomic Bose-Einstein condensates, for large parameter intervals. Importantly, we find that the hopfion can be stabilized in a simple parabolic trap, without the need for trap rotation or inhomogeneous interactions. We supplement our spectral analysis by studying the dynamics of such stationary states; we find them to be robust against significant perturbations of the initial state. In the unstable regimes, we not only identify the unstable mode, such as a quadrupolar or hexapolar mode, but we also observe the corresponding instability dynamics. Furthermore, deep in the Thomas-Fermi regime, we investigate the particle-like behavior of vortex rings and hopfions.

Spectator Risks at Sporting Events
Creators: name: Winslow, James E. Tripp
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Over 15 million Americans attend professional sporting events every year, and many million more attend minor league affiliates of these teams. In recent years, interest has increased concerning injuries to spectators at these sporting events. Injuries have occurred to spectators across different sporting events and in many different ways. Spectator death and injury have occurred in hockey, baseball, and by race cars that have broken apart. Despite the known risk of mortality and morbidity to spectators, little scientific information exists to quantify the risk to spectators at sporting events or to discuss ways to reduce these risks. Many spectators may falsely assume that they are safe at such events, or that the owner/operators of sporting venues are insuring their safety and will take responsibility if the spectator is injured. This literature review will examine the different types of spectator injuries, discuss mechanisms of injury, examine the legal risks, and make suggestions for further research.
