description: We revisit a special model of gauge mediated supersymmetry breaking, the "R-invariant direct gauge mediation." We pay particular attention to whether the model is consistent with the minimal model of the μ-term, i.e., a simple mass term of the Higgs doublets in the superpotential. Although the incompatibility is highlighted in view of the current experimental constraints on the superparticle masses and the observed Higgs boson mass, the minimal μ-term can be consistent with the R-invariant gauge mediation model via a careful choice of model parameters. We derive an upper limit on the gluino mass from the observed Higgs boson mass. We also discuss whether the model can explain the 3σexcess of the Z+jets+$E_T^{\rm miss}$ events reported by the ATLAS Collaboration.

description: Nuclear magnetic resonance relaxometry represents a powerful tool for extracting dynamic information. Yet, obtaining links to molecular motion is challenging for many ions that relax through the quadrupolar mechanism, which is mediated by electric field gradient fluctuations and lacks a detailed microscopic description. For sodium ions in aqueous electrolytes, we combine ab initio calculations to account for electron cloud effects with classical molecular dynamics to sample long-time fluctuations, and obtain relaxation rates in good agreement with experiments over broad concentration and temperature ranges. We demonstrate that quadrupolar nuclear relaxation is sensitive to subpicosecond dynamics not captured by previous models based on water reorientation or cluster rotation. While ions affect the overall water retardation, experimental trends are mainly explained by dynamics in the first two solvation shells of sodium, which contain mostly water. This work thus paves the way to the quantitative understanding of quadrupolar relaxation in electrolyte and bioelectrolyte systems.

Inpatient complications and hospital characteristics for conventional and robotic-assisted laparoscopic hysterectomy for benign neoplasm of the uterus
Creators: name: Hoffman, Sarah

Year: 2014

description: Introduction: Robotic-assisted laparoscopic hysterectomy (RALH) for benign uterine conditions has been on the rise in the U.S. since the da Vinci system received regulatory clearance in 2005. There are currently no uniform standards for determining operating privileges with the device, and requirements vary by hospital. The present study examines how inpatient complications relate to hospital characteristics for robotic and non-robotic laparoscopic hysterectomies, using the largest public source of all-payer inpatient data in the U.S. Methods: All patients undergoing laparoscopic hysterectomy for benign neoplasm of the uterus were selected from the 2009-2011 Nationwide Inpatient Sample (NIS) core files. Patient and hospital characteristics were assessed for robotic and non-robotic procedures. Hospitals with complication rates in the top quartile were compared to hospitals with complication rates below the 75th percentile. Results were analyzed by chi-square and Fisher's exact tests in SAS 9.3 (SAS Institute, Inc., Cary, NC). Results: During the three year period, 5,079 women received robotic assisted laparoscopic hysterectomy for uterine fibroids while 13,587 underwent conventional laparoscopic hysterectomy. After restricting analysis to hospitals with 5 or more procedures, the 75th percentile for hospital complication rate was 12.5% for RALH (n=226 hospitals) and 11.1% for non-robotic procedures (n=633 hospitals). For RALH, there was a significant association between location (urban/rural) and complication rate, with more rural hospitals than expected falling into the higher complication group (chi-square = 7.99, p < 0.01). For non-robotic procedures, there was a significant association between teaching status and complication rate, with more teaching hospitals than expected falling into the high complication rate group (chi-square = 8.34, p < 0.01). Conclusion: This is the first study that we are aware of that examines hospital characteristics as they relate to complication rates for RALH. Data were analyzed without exploring patient characteristics that could relate to hospital selection as well as patient outcome. This study offers tentative evidence that hospital complication rate could be related to rural location and/or positive teaching status, leaving the question open for further investigation with a controlled analysis.

The Influence of State Variables on Early Intervention Policy Decisions, and Implications of these Decisions for the Effectiveness of Part C Programs

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Part C of the Individuals with Disabilities Education Act (IDEA) assures federal funds for the provision of Early Intervention (EI) services to children under the age of three with developmental delays. Although IDEA emphasizes the need for individualized and family-centered services, it remains otherwise vague in its policy requirements, allowing states to determine the details of their Part C programs' structures and service delivery. The resulting variation in states' Part C policies combined with the inherently individualized nature of EI services has befuddled recent movements to define and quantify service outcomes for child and family recipients of Early Intervention. This study attempts to characterize the processes and outcomes of Part C policy development at a state level in order to elucidate more and less successful strategies. I triangulated methods, combining a systematic review of published EI literature, analysis of public documents pertaining to Part C, and in-depth interviews with stakeholders in four states, in order to draw conclusions about what factors influence EI policy formation and program success. Similarities and differences across the four states indicate that the centralization of program structure, degree of interagency collaboration, advocacy of key spokespeople, political climate, and budgetary limitations all have important effects on Part C policies. Many of these variables also appear to enhance the quality of services delivered. However, the implications of programs' policy choices for the children and families they serve proved very difficult to determine, reaffirming the EI field's current need for and struggle with collecting outcome data. As OSEP's current reporting requirements move out of their infancy, compiling data at local, state, and national levels should facilitate further exploration of the relationship between state variables, Part C policy decisions, and benefits for the children and families that EI serves.

description: Radioactive contaminants on the surfaces of detector components can be a problematic source of background events for physics experiments searching for rare processes. Exposure to radon is a specific concern because it can result in the relatively long-lived $^{210}$Pb (and progeny) being implanted to significant subsurface depths such that removal is challenging. In this article we present results from a broad exploration of cleaning treatments to remove implanted $^{210}$Pb and $^{210}$Po contamination from silicon, which is an important material used in several rare-event searches. We demonstrate for the first time that heat treatments ("baking") can effectively mitigate such surface contamination, with the results of a 1200 $^{\circ}$C bake consistent with perfect removal. We also report results using wet-chemistry and plasma-based methods, which show that etching can be highly effective provided the etch depth is sufficiently aggressive. Our survey of cleaning methods suggests consideration of multiple approaches during the different phases of detector construction to enable greater flexibility for efficient removal of $^{210}$Pb and $^{210}$Po surface contamination

We show that in the case of such surfaces discrete uniformization via hyper-ideal circle patterns always exists and is unique. We also propose a numerical algorithm, utilizing convex optimization, that constructs the desired discrete uniformization.

Using the Community Health Assessment (CHA) to Reduce Racial Health Disparities within Gaston County’s African American Population
Creators: name: Eaton, Stephen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: In North Carolina, all local health departments are required to complete a community health assessment (CHA) every four years in order to achieve local health department accreditation. The intent of the CHA is to assess the local community’s health needs, recognize barriers to good health, understand perceptions of personal and community health, and pinpoint areas of population health inequities. The CHA effort is led by the local health department and is often achieved through collaboration with numerous stakeholders. The CHA team engages in activities that map resources, prioritize health issues, develop community health improvement strategies, and identify health disparities within local populations.The main objective of this paper is to examine the Gaston County Department of Health & Human Services’ use of the CHA in reducing racial health disparities within the county’s African American population, as these disparities are an important economic, social justice and public health issue. Previous CHAs have demonstrated that African Americans in Gaston County have experienced disproportionate rates of teen pregnancy, infant mortality and shorter life expectancy, compared to the white population. As Gaston County prepares for its 2017 CHA, this paper seeks to identify how Gaston County can better use the CHA to reduce racial health disparities in the county’s African American population. Recommendations are provided that promote continuous quality improvement of Gaston County’s CHA process and propose the following strategies for improvement: using the Community Based Participatory Research (CBPR) model as a strategy for increasing community engagement; ensuring proper representation of minority groups; and providing comprehensive training on cultural competency, the ecological model, and the way social determinants of health impact health outcomes.

description: Temporal Kerr cavity solitons are pulses of light that can persist in coherently-driven, dispersive resonators with Kerr-type nonlinearity. It is widely accepted that such solitons react to parameter inhomogeneities by experiencing a temporal drift whose rate is governed by the gradient of the parameter at the soliton's position. This result, however, assumes that the gradient of the inhomogeneity is constant across the soliton, which may not hold true under all situations, e.g. when using bichromatic driving or in the presence of third-order dispersion that gives rise to an extended dispersive wave tail. Here we report on theoretical and numerical results pertaining to the behavior of dissipative temporal Kerr cavity solitons under conditions where parameter inhomogeneities vary nonlinearly across the width of the soliton. In this case, the soliton velocity is dictated by the full overlap between its so-called neutral mode and the parameter perturbation, which we show can yield dynamics that are manifestly at odds with the common wisdom of motion dependent solely upon the gradient of the inhomogeneity. We also investigate how the presence of third-order dispersion and the associated dispersive wave tail changes the motion induced by parameter inhomogeneities. We find that the dispersive wave tail as such does not contribute to the soliton motion; instead, higher-order dispersion yields counter-intuitive influences on the soliton motion. Our results provide new insights to the behavior of temporal cavity solitons in the presence of parameter inhomogeneities, and can impact systems employing pulsed or bichromatic pumping and/or resonators with non-negligible higher-order dispersion.

description: We consider the Beltrami equation for hydrodynamics and we show that its solutions can be viewed as instanton solutions of a more general system of equations. The latter are the equations of motion for an ${\cal N}=2$ sigma model on 4-dimensional worldvolume (which is taken locally HyperKähler) with a 4-dimensional HyperKähler target space. By means of the 4D twisting procedure originally introduced by Witten for gauge theories and later generalized to 4D sigma-models by Anselmi and Fré, we show that the equations of motion describe triholomophic maps between the worldvolume and the target space. Therefore, the classification of the solutions to the 3-dimensional Beltrami equation can be performed by counting the triholomorphic maps. The counting is easily obtained by using several discrete symmetries. Finally, the similarity with holomorphic maps for ${\cal N}=2$ sigma on Calabi-Yau space prompts us to reformulate the problem of the enumeration of triholomorphic maps in terms of a topological sigma model.

description: The Fermi paradox has given rise to various attempts to explain why no evidence of extraterrestrial civilisations was found so far on Earth and in our Solar System. Here, we present a dynamical model for the development of such civilisations, which accounts for self-destruction, colonisation and astrophysical destruction mechanisms of civilisations including gamma-ray bursts, type Ia and type II supernovae as well as radiation from the supermassive black hole. We adopt conservative estimates regarding the efficiency of such processes and find that astrophysical effects can influence the development of intelligent civilisations and change the number of systems with such civilisations by roughly a factor of 2; potentially more if the feedback is enhanced. Our results show that non-equilibrium evolution allows for solutions in-between extreme cases such as "rare Earth" or extreme colonisation, including scenarios with civilisation fractions between 10^{-2} and 10^{-7}. These would imply still potentially large distances to the next such civilisations, particularly when persistence phenomena are being considered. As previous studies, we confirm that the main uncertainties are due to the lifetime of civilisations as well as the assumed rate of colonisation. For SETI-like studies, we believe that unbiased searches are needed considering both the possibilities that the next civilisations are nearby or potentially very far away.

description: Given a nonnegative matrix factorization, $R$, and a factorization rank, $r$, Exact nonnegative matrix factorization (Exact NMF) decomposes $R$ as the product of two nonnegative matrices, $C$ and $S$ with $r$ columns, such as $R = CS^\top$. A central research topic in the literature is the conditions under which such a decomposition is unique/identifiable, up to trivial ambiguities. In this paper, we focus on partial identifiability, that is, the uniqueness of a subset of columns of $C$ and $S$. We start our investigations with the data-based uniqueness (DBU) theorem from the chemometrics literature. The DBU theorem analyzes all feasible solutions of Exact NMF, and relies on sparsity conditions on $C$ and $S$. We provide a mathematically rigorous theorem of a recently published restricted version of the DBU theorem, relying only on simple sparsity and algebraic conditions: it applies to a particular solution of Exact NMF (as opposed to all feasible solutions) and allows us to guarantee the partial uniqueness of a single column of $C$ or $S$. Second, based on a geometric interpretation of the restricted DBU theorem, we obtain a new partial identifiability result. This geometric interpretation also leads us to another partial identifiability result in the case $r=3$. Third, we show how partial identifiability results can be used sequentially to guarantee the identifiability of more columns of $C$ and $S$. We illustrate these results on several examples, including one from the chemometrics literature.

description: We investigate simultaneous state-insensitive trapping of a mixture of two different atomic species, Caesium and Rubidium. The magic wavelengths of the Caesium and Rubidium atoms are different, $935.6$ nm and $789.9$ nm respectively, thus single-frequency simultaneous state-insensitive trapping is not possible. We thus identify bichromatic trapping as a viable approach to tune the two magic wavelengths to a common value. Correspondingly, we present several common magic wavelength combinations appropriate for simultaneous state-insensitive trapping of the two atomic species.

description: Objective: To compare workforce outcomes, including primary care specialty choice and practice location in underserved areas, between graduates of the University of North Carolina at Chapel Hill's School of Medicine (UNC SOM) Medical Doctor (MD) and combined Medical Doctor/Masters in Public Health (MD/MPH) programs Methods: We completed a retrospective cohort analysis of UNC SOM students who graduated between 2007 and 2009. Graduates were tracked using a combined national and statewide North Carolina (NC) physician database maintained at the Cecil G. Sheps Center for Health Services Research at the University of North Carolina in Chapel Hill. Workforce outcomes assessed included primary care residency choice at graduation and specialty five years after graduation. Additional outcomes included whether practice was in a rural location and characteristics of these locations including Medicaid eligibility, per capita income, unemployment, economic tier status, and racial composition. Results: Out of 474 graduates from UNC-SOM between 2007 and 2009, 72 (15%) completed an MPH in addition to their MD. No significant differences were found between demographics of graduates and the completion of an MPH. We also found no difference in workforce outcomes between students who completed an MPH and those who did not. Implications: Changes in the health care system are leading to changes in medical education in the United States. Many schools, including the University of North Carolina SOM have created programs allowing medical students to earn an MPH degree in addition to their medical degree yet little is known about workforce outcomes from these programs. Pursuit of an MPH among medical students does not appear to be associated with a primary care or rural practice outcomes. Other possible differences in workforce outcomes between students pursuing vs not pursing an MPH are worth further research such as conducting community health assessments or participation in public health programs.

description: We report on the first joint analysis of observational signatures from the electroweak baryogenesis in both gravitational wave (GW) detectors and particle colliders. With an effective extension of the Higgs sector in terms of the dimension-6 operators, we derive a strong first-order phase transition in associated with a sizable CP violation to realize a successful electroweak baryogenesis. We calculate the GW spectrum resulting from the bubble nucleation, plasma transportation, and magnetohydrodynamic turbulence of this process that occurred after the big bang, and find that it yields GW signals testable in Evolved Laser Interferometer Space Antenna, Deci-hertz Interferometer Gravitational wave Observatory and Big Bang Observer. We further identify collider signals from the same mechanism that are observable at the planning Circular Electron Positron Collider. Our analysis bridges astrophysics/cosmology with particle physics by providing significant motivation for searches for GW event peaking at the $(10^{-4}, 1)$ Hz range, which are associated with signals at colliders, and highlights the possibility of an interdisciplinary observational window into baryogenesis. The technique applied in analyzing early universe phase transitions may enlighten the study of phase transitions in applied science.

Controlling Urban Malaria in Africa: Operational Guidance for Program Managers
Creators: name: Fotheringham, Megan

description: Background: Malaria remains a significant global public health challenge. In 2010, out of an estimated 216 million episodes of malaria, the disease killed 655,000 people. While most malaria cases in Africa occur in rural settings, urban malaria is a unique public health problem that requires specific consideration. With Africa’s rapid pace of urbanization, coupled with specific dynamics of urban settings that facilitate transmission, it is expected that malaria will remain an important public health concern for urban populations. Reduced amounts of international funding, waning international and domestic political commitment, and emerging insecticide resistance among the anopheles mosquitoes, are all factors that in combination require malaria experts to develop a customized urban malaria control program for the 21st century that is smarter, more cost effective, with targeted interventions. Methods: This paper reports on an extensive literature search using the PubMed database to identify contemporary urban malaria studies, research past urban malaria control programs, and analyze currently available control interventions. The data gathered were used to determine the malaria risk factors associated with urban settings and identify essential components of successful urban malaria control programs. Results: Urban settings experience a high level of heterogeneity in malaria transmission. Successful programs in these settings should have multiple, complementary interventions that can be adapted in response to context-specific dynamics of malaria incidence. Conclusions: Urban malaria control programs should use the five-step tool developed and presented in this paper to: a) identify and map the disease burden, b) identify the appropriate strategy, goal and objective; c) select the appropriate interventions; d) expand partnerships to include (among others) the private sector; and e) continue monitoring program progress to ensure that it remains responsive to the urban epidemiological profile.

description: In this article we review the present knowledge on the elastic properties of membranes of biological origin. Assuming the fluid mosaic hypothesis, we consider the phospholipid bilayer as the structural base of a biological membrane. We expose a model due to Helfrich which can be used to obtain an expression for the membrane elastic energy. The free energy is completely characterized by two local principal curvatures and four parameters that depend on the chemical composition of the membrane and its local environment. In addition we present the theoretical justification of an experimental method (the Micropipette Manipulation technique) that may be used to measure the membrane rigidity. Finally, we describe some physical consequences of these concepts, such as the explanation of the lamellar-sponge phase transition and the emergence of the steric interaction between membranes. ------ Se presenta una revisión del conocimiento actual sobre las propiedades elásticas de las membranas. Bajo la hipótesis del mosaico fluido se considera a una bicapa de fosfolípido como la base estructural de una membrana biológica y se expone un modelo debido a Helfrich a partir del cuál se obtiene una expresión para la energía elástica de una membrana. La energía libre queda completamente caracterizada por sus curvaturas locales principales y cuatro parámetros dependientes de la composición química de la membrana y de su entorno local. Se expone la justificación teórica de un método experimental que permite medir la constante elástica de curvatura media de una membrana. Finalmente se describen algunas consecuencias físicas de estos conceptos, como la explicación de la transición de una fase lamelar a una esponja, o la aparición de la interacción estérica entre membranas.

description: We carefully revisit the mass hierarchies for the KKLT scenario with an uplift term from an anti D3-brane in a strongly warped throat. First, we derive the bound resulting from what is usually termed "the throat fitting into the bulk" directly from the Klebanov-Strassler geometry. Generating the small value of the superpotential $W_{0}$ via the mechanism proposed by Demirtas, Kim, McAllister and Moritz (DKMM), we identify two possible DKMM-refined KKLT scenarios for stabilizing the light axio-dilaton modulus. The first scenario spoils the expected hierarchy between the bulk and the throat mass scales and implies that the energy scale of the uplift is larger than the species scale of the effective theory in the throat. Moreover it requires an unnaturally large tadpole $N\sim 10^{7-8}$ that is certainly in conflict with tadpole cancellation. For the less restricted second scenario, the hierarchy can be controlled at the expense of, under the most optimistic assumptions, an only moderately large tadpole $N\sim 10^{2-3}$.
