description: We present a high-resolution kinematic study of the massive main-sequence star-forming galaxy (SFG) SDSS J090122.37+181432.3 (J0901) at z=2.259, using 0.36 arcsec ALMA CO(3-2) and 0.1-0.5 arcsec SINFONI/VLT H-alpha observations. J0901 is a rare, strongly-lensed but otherwise normal massive (log(M_star/M_sun)~11) main sequence SFG, offering a unique opportunity to study a typical massive SFG under the microscope of lensing. Through forward dynamical modeling incorporating lensing deflection, we fit the CO and H-alpha kinematics in the image plane out to about one disk effective radius (R_e ~ 4 kpc) at a ~600pc delensed physical resolution along the kinematic major axis. Our results show high intrinsic dispersions of the cold molecular and warm ionized gas (sig0_mol ~ 40 km/s and sig0_ion ~ 66 km/s) that remain constant out to R_e; a moderately low dark matter fraction (f_DM(R_e) ~ 0.3-0.4) within R_e; and a centrally-peaked Toomre Q-parameter -- agreeing well with the previously established sig0 vs. z, f_DM vs. Sig_baryon, and Q's radial trends using large-sample non-lensed main sequence SFGs. Our data further reveal a high stellar mass concentration within ~1-2 kpc with little molecular gas, and a clumpy molecular gas ring-like structure at R ~ 2-4 kpc, in line with the inside-out quenching scenario. Our further analysis indicates that J0901 had assembled half of its stellar mass only ~400 Myrs before its observed cosmic time, and cold gas ring and dense central stellar component are consistent with signposts of a recent wet compaction event of a highly turbulent disk found in recent simulations.

Strategies to Engage Community Stakeholders as Public Health Advocates and Assets

description: In North Carolina, the mission of public health is to promote and protect the highest possible level of health for all residents. The ten essential services of public health serve as performance standards that promote continuous quality improvement of public health systems, strengthen the science base for public health practice improvement, and encourage and leverage national, state, and local partnerships to build a stronger foundation for public health preparedness. Currently, stakeholders and community members are surveyed every four years using community health assessment tools. Our communities are not being fully recognized and utilized as solvers of needs. Stakeholders are assets and should be identified, marketed, and developed as public health partners. The local public health system has the opportunity to pffer its community more than the interpretation of periodic community health assessments mandated by the governor. In August 2005, a field project to fulfill requirements for a Masters in Public Health Leadership focused on marketing public health to rural NC counties. A stakeholder survey was done to improve, market, emphasize, and help interpret the local district health department's mission statement: Public Health: protecting and improving your health throughout life. The local health department system should use a variety of methods to improve the community's health. Partnership with media is foundational. Web site based information should be developed by the health department as a community service. Periodic stakeholder assessments should be planned as useful monitoring tools between the four year cycles of formal Community Health Assessments. The periodic assessments should then result in timely feedback and education to each stakeholder.

description: In a previous paper, the authors introduced the idea of a symmetric pair of operators as a way to compute self-adjoint extensions of symmetric operators. In brief, a symmetric pair consists of two densely defined linear operators $A$ and $B$, with $A \subseteq B^\star$ and $B \subseteq A^\star$. In this paper, we will show by example that symmetric pairs may be used to deduce closability of operators and sometimes even compute adjoints. In particular, we prove that the Malliavin derivative and Skorokhod integral of stochastic calculus are closable, and the closures are mutually adjoint. We also prove that the basic involutions of Tomita-Takesaki theory are closable and that their closures are mutually adjoint. Applications to functions of finite energy on infinite graphs are also discussed, wherein the Laplace operator and inclusion operator form a symmetric pair.

description: Most of the planetary systems discovered around binary stars are located at approximately three semi-major axes from the barycentre of their system, curiously close to low-order mean-motion resonances (MMRs). The formation mechanism of these circumbinary planets is not yet fully understood. In situ formation is extremely challenging because of the strong interaction with the binary. One possible explanation is that, after their formation, the interactions between these planets and the surrounding protoplanetary disc cause them to migrate at velocities dependent on the nature of the disc and the mass of the exoplanet. Although extensive data can be obtained with direct hydrodynamical simulations, their computational cost remains too high. On the other hand, the direct n-body simulations approach allows us to model a large variety of parameters at much lower cost. We analyse the planetary migration around a wide variety of binary stars using Stokes-like forces that mimic planetary migration at a constant rate. Our goal is to identify the main parameters responsible for the ejection of planets at different resonances with the inner binary. We performed 4200 n-body simulations with Stokes-like forces and analysed their evolution and outcome as a function of the properties of each system. For each simulated exoplanet, we applied an ensemble learning method for classification in order to clarify the relationship between the inspected parameters and the process of MMR capture. We identify the capture probability for different N/1 MMRs, 4/1 being the most prone to capture exoplanets, with 37% probability, followed by MMR 5/1 with $\sim$ 23% of probability. The eccentricity of the binary is found to be the most important parameter in determining the MMR capture of each circumbinary exoplanet, followed by the mass ratio of the binary and the initial eccentricity of the planet.

Lower extremity ultrasound performed after removal of femoral central venous catheters to detect deep venous thrombosis and prevent pulmonary embolism among the critically ill: A cost-effectiveness analysis
Creators: name: Cox, Christopher E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Background: Femoral central venous catheter (CVC) use is complicated by a high risk of proximal deep venous thrombosis (DVT). DVTs may result in potentially harmful pulmonary embolism (PE). Performing routine ultrasound after removal of femoral catheters to detect DVT and thus prevent pulmonary embolism (PE) has been suggested, but the potential cost-effectiveness of this strategy has not been examined. Objective: To evaluate the potential cost-effectiveness of routine unilateral duplex Doppler ultrasound versus no imaging study in averting PE-associated deaths associated with femoral CVCs among the critically ill. Design: Decision model. Data sources: Probabilities for clinical outcomes were obtained from metaanalyses of clinical trials and literature syntheses of other prospective studies. Cost estimates were derived from average physician and Medicare reimbursements, institutional costs, and other sources. Target population: Mechanically ventilated 60-year old patients with femoral CVCs treated in a medical intensive care unit (ICU) for acute respiratory failure. Time horizon: Duration of hospitalization. Perspective: Health care payer. Intervention: Unilateral duplex ultrasound examination of the proximal veins of the lower extremity performed after removal of a femoral CVC versus no ultrasound examination. -- Outcome Measures: Costs, costs per PE-associated death and per PE averted, and incremental cost-effectiveness ratios. Results of Base-Case Analysis: A strategy of screening ultrasound cost $14,350 per PE death and $1,969 per PE averted compared with no imaging test. Results of Sensitivity Analyses: In one-way sensitivity analyses, the ultrasound strategy ranged from cost-saving to costs of $151,703 per PE death prevented after varying prevalence of CVC-associated DVT, probability of PE associated with DVT, sensitivity and specificity of ultrasound for DVT, and probability of eligibility to receive low-molecular weight heparin versus an Inferior vena cava (IVC) filter. Conclusions: A strategy of performing ultrasound after removing femoral CVCs appears to be a cost-effective modality in reducing both PE and PE deaths associated with CVCs among the critically ill. If further study confirms the benefits of preventing catheter-associated venous thromboembolic disease among the critically ill, then this study suggests that these improved outcomes come at acceptable costs for this population.

description: Adiabatic scanning calorimetry (ASC) is capable of providing simultaneously the specific enthalpy h(T) and the specific heat capacity cp(T), and is an important tool to determine the order of transitions and to render high-resolution information on pretransitional thermal behavior. Here we report on ASC results on the compound DIO and on mixtures with RM734. Both compounds exhibit a low-temperature ferroelectric nematic phase (NF) and a high-temperature paraelectric nematic (N). In DIO these two phases are separated by an intermediate phase (Nx). Detailed data of h(T) and cp(T), indicated that the intermediate phase was present in all mixtures over the complete composition range, albeit with strongly decreasing temperature width with decreasing mole fraction of DIO (xDIO). The xDIO dependence of the two transitions could be well described by a quadratic function and both transitions were weakly first order. The true latent heat of the Nx-N transition of DIO was as low as 0.0075 +/- 0.0005 J/g and 0.23 +/- 0.03 J/g for the NF-Nx transition, about twice the previously reported value of 0.115 J/g for the NF-N transition in RM734. In the mixtures both transition latent heats decrease gradually with decreasing xDIO. At all the Nx-N transitions pretransition fluctuation effects are absent and these transitions are purely but very weakly first order. As in RM734 the transition from the NF to the higher temperature phase exhibits substantial pretransitional behaviour. Power law analysis of cp(T) resulted in an effective critical exponent of 0.88 +/- 0.10 for DIO and this value decreased in mixtures with decreasing xDIO towards 0.50 +/- 0.05 reported for RM734. Ideal mixture analysis of the phase diagram was consistent with ideal mixture behavior for the total transition enthalpy change

description: This paper contains description of such knowledge representation model as Object-Oriented Dynamic Network (OODN), which gives us an opportunity to represent knowledge, which can be modified in time, to build new relations between objects and classes of objects and to represent results of their modifications. The model is based on representation of objects via their properties and methods. It gives us a possibility to classify the objects and, in a sense, to build hierarchy of their types. Furthermore, it enables to represent relation of modification between concepts, to build new classes of objects based on existing classes and to create sets and multisets of concepts. OODN can be represented as a connected and directed graph, where nodes are concepts and edges are relations between them. Using such model of knowledge representation, we can consider modifications of knowledge and movement through the graph of network as a process of logical reasoning or finding the right solutions or creativity, etc. The proposed approach gives us an opportunity to model some aspects of human knowledge system and main mechanisms of human thought, in particular getting a new experience and knowledge.

description: The companion paper "Higher-order in time quasi-unconditionally stable ADI solvers for the compressible Navier-Stokes equations in 2D and 3D curvilinear domains", which is referred to as Part I in what follows, introduces ADI (Alternating Direction Implicit) solvers of higher orders of temporal accuracy (orders $s = 2$ to $6$) for the compressible Navier-Stokes equations in two- and three-dimensional space. The proposed methodology employs the backward differentiation formulae (BDF) together with a quasilinear-like formulation, high-order extrapolation for nonlinear components, and the Douglas-Gunn splitting. A variety of numerical results presented in Part I demonstrate in practice the theoretical convergence rates enjoyed by these algorithms, as well as their excellent accuracy and stability properties for a wide range of Reynolds numbers. In particular, the proposed schemes enjoy a certain property of "quasi-unconditional stability": for small enough (problem-dependent) fixed values of the time-step $Δt$, these algorithms are stable for arbitrarily fine spatial discretizations. The present contribution presents a mathematical basis for the performance of these algorithms. Short of providing stability theorems for the full BDF-ADI Navier-Stokes solvers, this paper puts forth proofs of unconditional stability and quasi-unconditional stability for BDF-ADI schemes as well as some related un-split BDF schemes, for a variety of related linear model problems in one, two and three spatial dimensions, and for schemes of orders $2\leq s\leq 6$ of temporal accuracy. Additionally, a set of numerical tests presented in this paper for the compressible Navier-Stokes equation indicate that quasi-unconditional stability carries over to the fully non-linear context.

description: A critical step towards certifying safety-critical systems is to check their conformance to hard real-time requirements. A promising way to achieve this is by building the systems from pre-verified components and verifying their correctness in a compositional manner. We previously reported a formal approach to verifying function blocks (FBs) using tabular expressions and the PVS proof assistant. By applying our approach to the IEC 61131-3 standard of Programmable Logic Controllers (PLCs), we constructed a repository of precise specification and reusable (proven) theorems of feasibility and correctness for FBs. However, we previously did not apply our approach to verify FBs against timing requirements, since IEC 61131-3 does not define composite FBs built from timers. In this paper, based on our experience in the nuclear domain, we conduct two realistic case studies, consisting of the software requirements and the proposed FB implementations for two subsystems of an industrial control system. The implementations are built from IEC 61131-3 FBs, including the on-delay timer. We find issues during the verification process and suggest solutions.

description: The current analysis is dedicated to a detailed investigation of the non-Local Thermodynamic Equilibrium (NLTE) effects influencing the formation of the Fe I 6173 A line, which is widely used by many instruments including the Helioseismic and Magnetic Imager (HMI) on-board the Solar Dynamics Observatory (SDO) and the Polarimetric and Helioseismic Imager on board the Solar Orbiter. We synthesize the Stokes profiles in a snapshot of a three dimensional magnetohydrodynamic simulation of the solar photosphere under both LTE and NLTE conditions. The simulation cube contains a sunspot and a plage region around it. The LTE and NLTE Stokes profiles formed in different features are compared and analysed. NLTE effects are evident in both intensity and polarization profiles. For the 6173 A line, UV overionization is the dominant NLTE mechanism, and scattering effects are much less important. In addition to Fe, an NLTE treatment of Si, Mg and Al is necessary to set the right photon density in the UV. This is found to further enhance the LTE departures compared to the case where Fe alone is treated in NLTE. These effects in the Stokes profiles survive even when the profiles are averaged spatially or sampled on a coarse wavelength grid such as that used by the SDO/HMI and other magnetographs. The deviations from the LTE profiles are stronger in the Fe I 6173 A compared to the 6301 A - 6302 A lines because in case of the latter, line scattering compensates the effect of UV overionization. Based on the nature of departures from LTE, treating the 6173 A line in LTE will likely result in an over-estimation of temperature and an under-estimation of the magnetic field strength.

description: Currently, Singapore imports more than 90% of the food consumed. In order to be less reliant on external sources, Singapore aims to produce 30% of its nutritional needs by 2030 through alternative spaces for farming such as a Container-based Aquaponics System (CAS). This paper outlines the study into determining the optimal photovoltaics (PV) panel configuration on a CAS, which would ensure optimal daylight passing through and, as a result, allows for the favourable growth of crops. As these container-based aquaponics systems have yet to be implemented locally, the PV panel design of this CAS was studied and developed with reference to overseas case studies. A comprehensive review of the relevant case studies and lighting parameters such as Photosynthetic Photon Flux Density (PPFD) and Daily Lighting Integral (DLI) was performed, followed by a site investigation to examine if the conversion factor is influenced by the climate classification, sky conditions, and sunlight spectrum changes. The modelling process was carried out in Revit and Rhino, whereas the simulation processes were conducted with ClimateStudio. Based on the analysis and comparison of the research findings, the ideal container arrangement and PV installation (involving the transparency rate and tilt angle) that promoted the favourable growth of the crops was then recommended. Through this paper, the benefits of the CAS were studied; it was found that the CAS could increase crop yield towards the goal of food security. The findings from this study can provide a valuable basis for designing container-based aquaponics systems in metropolitan contexts with tropical climates, such as Singapore and other densely populated cities in Southeast Asia. By offering insights into optimizing daylight use and PV panel configurations, this research has the potential to increase the feasibility and efficiency of such systems in these regions. As a result, it contributes to the pursuit of sustainable urban farming and underscores the importance of alternative farming spaces in fostering a more self-reliant and environmentally conscious future.
The Effect of Integrated Breastfeeding Support in an Academic Family Medicine Clinic

description: Background: Despite the importance of breastfeeding, most U.S. women do not meet recommendations for length of any or exclusive breastfeeding. Support in primary care settings is a recommended intervention (USPSTF 2016), but optimal strategies to implement this support are not well-established. We sought to evaluate the effect on any and exclusive breastfeeding of implementing integrated breastfeeding support within an academic family medicine clinic. Methods: We conducted a retrospective chart review of all infants 10 months before and 10 months following the implementation of integrated breastfeeding support provided by an IBCLC or MD-IBCLC. 281 infants were identified, 140 before implementation and 141 after. A trained research assistant extracted data from the electronic medical record, including demographics, relevant medical history, and infant diet at 2, 4 and 6 months into a Qualtrics tool. Bivariate and multiple logistic regression analyses were performed in STATA. Results: There were no significant demographic differences before and after the intervention. The proportion of infants who were breastfed at 2, 4, and 6 months was greater in the post-implementation group (71.7% vs. 86.7% at 2 months, p=0.05; 61.5% vs. 77.1% at 4 months, p=0.08; and 50.7% vs. 64.4%, p=0.09 at 6 months). The proportion of infants who were exclusively breastfed was also greater in the post-implementation group (58.7% to 77.8% at 2 months; p=0.04, 50.5% to 54.2% at 4 months, p=0.06; and 44.0% to 49.3% at 6 months, p=0.12). Logistic regression models showed similar results, and controlling for a priori determined covariates of interest increased the odds of any and exclusive breastfeeding at all time points. Conclusion: Providing integrated, IBCLC breastfeeding support services within an academic family medicine clinic is associated with significant increases in in any and exclusive breastfeeding. These results support the provision of lactation services onsite at locations where mothers and children receive primary care.

description: Institutions and investors are constantly faced with the challenge of appropriately distributing endowments. No budget is limitless and optimising overall spending without sacrificing positive outcomes has been approached and resolved using several heuristics. To date, prior works have failed to consider how to encourage fairness in a population where social diversity is ubiquitous, and in which investors can only partially observe the population. Herein, by incorporating social diversity in the Ultimatum game through heterogeneous graphs, we investigate the effects of several interference mechanisms which assume incomplete information and flexible standards of fairness. We quantify the role of diversity and show how it reduces the need for information gathering, allowing us to relax a strict, costly interference process. Furthermore, we find that the influence of certain individuals, expressed by different network centrality measures, can be exploited to further reduce spending if minimal fairness requirements are lowered. Our results indicate that diversity changes and opens up novel mechanisms available to institutions wishing to promote fairness. Overall, our analysis provides novel insights to guide institutional policies in socially diverse complex systems.

description: Purpose To examine if there is a subset of men with Gleason 7 (3+4) prostate cancer who may be potential candidates for active surveillance. Materials and Methods We used the SEARCH database to identify 870 men undergoing radical prostatectomy from 2001-13 with >8 biopsy cores and complete clinical information. We compared characteristics of men who fulfilled low-risk disease criteria (clinical stage T1c/T2a; biopsy Gleason ≤6; PSA ≤10 ng/mL) with the exception of biopsy Gleason 7 (3+4) vs. men who met all 3 low-risk criteria. Logistic regression was used to test the association between biopsy Gleason and pathological features. Biochemical recurrence was examined using Cox hazards analysis. To examine whether there was a subset of men with low-volume Gleason 7 with comparable outcomes to low-risk men, we repeated all analyses limiting the percentage positive cores to ≤33% and positive cores to ≤4, ≤3, or ≤2. Results Gleason 7 low-risk men had increased risk of pathological Gleason ≥4+3 (p<0.001), positive margins (p=0.070), extracapsular extension (p<0.001), seminal vesicle invasion (p=0.005), and higher biochemical recurrence (HR 1.65, p=0.006). Using increasingly strict definitions of low-volume disease, at ≤3 positive cores there was no difference in adverse pathology between groups (all p>0.1), except higher pathological Gleason score (p<0.001). Biochemical recurrence was similar in men with Gleason 6 or Gleason 7 (3+4) (HR 1.39; p=0.254). Conclusion Among men with PSA≤10 ng/mL and clinical stage T1c/T2a, those with Gleason 7 (3+4) in ≤3 total positive cores have similar rates of adverse pathology and biochemical recurrence as men with Gleason ≤6.

description: Let $A$ be a commutative Banach algebra and $X$ be a compact space. The class of Banach $A$-valued function algebras on $X$ consists of subalgebras of $C(X,A)$ with certain properties. We introduce the notion of $A$-characters on an $A$-valued function algebra $\A$ as homomorphisms from $\A$ into $A$ that basically have the same properties as the evaluation homomorphisms $\cE_x:f\mapsto f(x)$, with $x\in X$. For the so-called natural $A$-valued function algebras, such as $C(X,A)$ and $\Lip(X,A)$, we show that $\cE_x$ ($x\in X$) are the only $A$-characters. Vector-valued characters are utilized to identify vector-valued spectrums. When $A=\C$, Banach $A$-valued function algebras reduce to Banach function algebras, and $A$-characters reduce to characters.

description: Child Care Health Consultation has developed as a profession only in the last few decades. As more and more children are attending out-of-home child care programs the need for improvements in the quality of child care has been noted. One way that this need for high quality child care programs is being addressed is in the area of health and safety practices in child care. The profession of Child Care Health Consultant has been a direct result of this need for improvement in health and safety practices in child care. In this paper I have examined the history of Child Care Health Consultation, the benefits, barriers, and cost of Child Care Health Consultation, how different states have implemented Child Care Health Consultant initiatives, and have outlined recommendations for the expansion and long term sustainability of Child Care Health Consultation in North Carolina.
Possible solution of the puzzle for the branching ratio and $CP$ violation in $B\to ππ$ decays with a modified perturbative QCD approach

description: We study $B\to ππ$ decay with a modified perturbative QCD approach. The branching ratios and $CP$ violation are calculated with the transverse momenta of partons considered. Sudakov factor associated with each meson is included to suppress soft contribution in QCD. With the wave function of $B$ meson obtained in QCD-inspired relativistic potential model being used, the suppression of Sudakov factor to the soft contribution is not effective enough. Soft scale cutoff and soft form factors of $Bπ$ transition and $ππ$ production have to be introduced. The main next-to-leading-order contributions of vertex correction, the quark-loop and magnetic penguin are included. To solve the long-standing puzzle in $B\toππ$ decay, that is the theoretical prediction of the branching ratio of $B^0\to π^0π^0$ being seriously smaller than experimental data, color-octet matrix element which is of long-distance dynamics is introduced. With parameters taken with reasonable values, all the branching ratios and $CP$ violation are well consistent with experimental data.

description: Timed Transition Models (TTMs) are event-based descriptions for modelling, specifying, and verifying discrete real-time systems. An event can be spontaneous, fair, or timed with specified bounds. TTMs have a textual syntax, an operational semantics, and an automated tool supporting linear-time temporal logic. We extend TTMs and its tool with two novel modelling features for writing high-level specifications: indexed events and synchronous events. Indexed events allow for concise description of behaviour common to a set of actors. The indexing construct allows us to select a specific actor and to specify a temporal property for that actor. We use indexed events to validate the requirements of a train control system. Synchronous events allow developers to decompose simultaneous state updates into actions of separate events. To specify the intended data flow among synchronized actions, we use primed variables to reference the post-state (i.e., one resulted from taking the synchronized actions). The TTM tool automatically infers the data flow from synchronous events, and reports errors on inconsistencies due to circular data flow. We use synchronous events to validate part of the requirements of a nuclear shutdown system. In both case studies, we show how the new notation facilitates the formal validation of system requirements, and use the TTM tool to verify safety, liveness, and real-time properties.

description: Controlling the modal content coupled into an optical fiber can be desireable in many situations, e.g. for adjusting the sensitivity of the guided field distribution to external perturbations. For this purpose we used a monolithic setup of a phase plate at a fiber inpute facet to excite selectivly higher order modes, which theoretically can provide a mode purity of more than 99%. We investigated the capabilities of this approach by complete modal decomposition of the fiber output signals, considering the achievable mode purity with respect to several possible imperfections of the setup. The experiments are compared with detailed numerical simulations and show a high agreement. Additionally a comparison with a well known setup with free space phase plates was undertaken. This showed the monolithic setup to be energetically twice as efficient.

description: Hautkrebs ist eine der häufigsten Krebserkrankungen weltweit. In dieser Dissertation wurde die vielversprechende antikanzerogene Wirkung von kaltem Atmosphärendruckplasma (KAP) gegen Hautkrebs in vivo untersucht. KAP reduzierte das Tumorwachstum und erhöhte reaktive Spezies, ohne jedoch die Apoptose oder den Metabolismus im Tumor zu beeinflussen. KAP in Kombination mit small molecules zeigte synergistische antikanzerogene Effekte mit reduziertem Tumorwachstum. Diese Ergebnisse deuten darauf hin, dass KAP eine vielversprechende Option für die Behandlung von Hautkrebs sein könnte.
Understanding the shortage and maldistribution of pediatric subspecialty care in the United States: An application of the Institutional Analysis and Development Framework
Creators: name: Rodenbough, Anna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: In the United States, the number of children and adolescents with chronic health conditions is rapidly expanding. At present both medical and surgical pediatric subspecialists are in short supply and are poorly distributed regionally (Basco and Rimsza 2013; Goodman 2005; Mayer and Skinner 2009). The current system for allocation of pediatric subspecialty care is unsustainable and may result in worsening health outcomes for children who face barriers to access. The Institutional Analysis and Development Framework is a policy framework that can be used to both evaluate outcomes achieved within the current system and predict outcomes that would be achieved with specific policy reforms. When pediatric subspecialty care is viewed as an economic good, the IAD framework can be applied to devise ways to better allocate this precious resource to all American children.
