description: We report a new workflow for background-oriented schlieren (BOS), termed "physics-informed BOS," to extract density, velocity, and pressure fields from a pair of reference and distorted images. Our method uses a physics-informed neural network (PINN) to produce flow fields that simultaneously satisfy the measurement data and governing equations. For the high-speed flows of interest in this work, we specify a physics loss based on the Euler and irrotationality equations. BOS is a quantitative fluid visualization technique that is used to characterize high-speed flows. Images of a background pattern, positioned behind the target flow, are processed using computer vision and tomography algorithms to determine the density field. Crucially, BOS features a series of ill-posed inverse problems that require supplemental information (i.e., in addition to the images) to accurately reconstruct the flow. Current BOS workflows rely upon interpolation of the images or a penalty term to promote a globally- or piecewise-smooth solution. However, these algorithms are invariably incompatible with the flow physics, leading to errors in the density field. Physics-informed BOS directly reconstructs all the flow fields using a PINN that includes the BOS measurement model and governing equations. This procedure improves the accuracy of density estimates and also yields velocity and pressure data, which was not previously available. We demonstrate our approach by reconstructing synthetic data that corresponds to analytical and numerical phantoms as well as experimental measurements. Our physics-informed reconstructions are significantly more accurate than conventional BOS estimates. Further, to the best of our knowledge, this work represents the first use of a PINN to reconstruct a supersonic flow from experimental data of any kind.

Evaluation of the Sphere Project's Minimum Standards for Food Security and Nutrition in Addressing the Determinants of Acute and Chronic Food Insecurity in Women
Creators: name: Moore, Jennifer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The right to food was declared a universal human right in 1948, yet hunger still affects 805 million people globally. Women are often disproportionately affected by food insecurity due to sociopolitical factors they face on a daily basis (Anderson, 1994). Women are frequently denied equal land and water rights, agricultural inputs, and decision making power directly impacting their health and the health of their household (Karl, 2009). These baseline living conditions are often exacerbated during times of crisis. The Sphere Project was a collaborative initiative by the International Red Cross/Red Crescent Movement and several NGOs to improve the quality of humanitarian work and develop humanitarian organization accountability. The Sphere standards are a set of globally accepted minimum standards in areas of water, hygiene, and sanitation; food security and nutrition; sheltering, settlement, and non-food items; and health action that should be reached during every humanitarian response. This paper researches the determinants of women's food security and reviews if the Sphere minimum standards address the gender specific factors affecting women and food security.

Infant Mortality in the United States: Regions, Race, and Reasons

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

description: The infant mortality rate is the number of infants per 1,000 live births who die in the first year of life. Worldwide, infant mortality is used an indicator of the health status of countries and states, as well as to gauge differences in health status among groups of people within a population. While the United States has one of the most technologically advanced medical care systems among industrialized countries, it currently ranks 46th in infant mortality. At the beginning of the twentieth century the overall infant mortality rate was estimated to be as high as 100 per 1,000 live births. The infant mortality rate has continued to decrease among minorities and whites, but there is a marked disparity in mortality rates between the two groups. The gap is closing but according to the 2007 rates, infant mortality among African Americans is still more than two times higher than other groups. An analysis of infant mortality by region shows that the regional demographic differences also correlate to racial trends in infant mortality. The burden of infant mortality has substantial financial and psychological costs to both individuals and society as a whole. In the past, researchers have often sought the magic bullet or one-stop solution to the problem of infant mortality in the United States, and the racial and ethnic disparities that exist. However, it is unlikely, as much as the public health and medical communities may wish it to be so, that one single answer is the key. It is more likely that a complex set of solutions, from many different fronts, will be needed to make the goal of an overall infant mortality rate of 4.5 per 1,000 live births set for 2010 a reality by 2020.
Identification of target system operations. 1. Determination of the time of the actual completion of the target operation

Publisher: name: arXiv
Year: 2015
Subjects: subject: Optimization and Control (math.OC)

description: It was found in the paper that the time frames of the studied system operation depend on the research objective. In cases when it comes to problems, related to the physical movement of the input and output products, limits of the study are defined by the time of the beginning of the movement of the first input product of the operation and ends with the time of issue of the last output product of the operation by the system. Time of completion of the physical movement of products is defined in the paper as the time of the physical completion of the operation. Since the purpose of any operation is to increase the value of the output products in relation to the value of input products of the operation, in cases when there is a problem of investigating the target operation, the time of completion of the target operation is determined not by the physics of the process, but its cybernetics. Since for the time of the operation, conversion processes link input products in time, the added value of output products is intended to compensate in time the costs of temporary binding of input products that initially have their value. The time, when the added value of output products of the target operation compensates the value of tight input products for the time of the operation, is defined in the paper as the time of the actual completion of the target operation. A system of notations to describe the system processes of target operations was proposed. The expressions for the numerical and analytical determination of the time of actual completion of the target operation were obtained. A link to the resource, with examples of calculations of the time of the actual completion of the operation with the use of numerical methods and analytic expressions, obtained in the paper was given.

Curricular Experiences in Primary Care: A Strategy for Increasing the Number of Medical Students Selecting Careers in Primary Care
Creators: name: Lahlou, Rita
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: With falling numbers of graduating medical students choosing careers in primary care and a growing population with expanding insurance coverage, the shortage of primary care providers in the United States is becoming larger. Some strategies to address this shortage include using mid-level providers, programs encouraging retention of primary care physicians, and incentives to attract such physicians to needed settings. Additionally, increasing the number of medical students choosing a career in primary care is necessary to expand the workforce. The purpose of this master’s paper is to explore the ways in which curricular experiences in medical school can influence students’ specialty choice, in hopes of understanding how such experiences can generate interest in primary care and expand the workforce. This paper begins with a systematic review evaluating recent literature describing curricular interventions meant to increase the number of medical students choosing a primary care specialty. Synthesis of the six articles included shows an association between early exposure to primary care experiences and graduates entering a primary care residency or career. Following the review is an original manuscript presenting the results of an evaluation of the Bloomer Hill Rural Health Course, a service-learning elective offered to second year medical students at the University of North Carolina. The components of this elective include: managing and volunteering at a free clinic, developing continuity relationships with patients, attending a monthly class covering primary care topics, keeping a reflective journal, and completing a community project. We evaluated the impact of this course by surveying a sample of 257 alumni who graduated between 2003 and 2007 to determine their type of practice, location of practice, patient population, and degree of community engagement. After adjustment for characteristics known to be associated with specialty choice, course participants were 5.5 times more likely than controls to choose a career in primary care. This evaluation is unique among many of those considered in the systematic review because it examines final specialty choice rather than intermediate outcomes, uses comparison groups to examine differences, and statistically adjusts for other factors known to be associated with specialty choice.

Publisher: name: Roma TrE-Press
Year: 2023

description: Just like Victor Frankenstein’s infamous monster, artificial intelligence is a devel- oping hodgepodge in need of supervision. The broad applicability of AI in its current, nascent state warrants specific regulation that addresses the need for (1) a uniform, legislative definition of artificial intelligence, (2) a determination of the requisite degree of human participation in artificial intelligence machine usage that is both sufficient and necessary for copyright protec- tion, (3) an ad hoc approach to future litigation involving artificial intelligence usage, and (4) both the precautionary and innovation principles to be considered as overarching guidance in the regulation of artificial intelligence. This paper provides a comparative analysis of United States and Italian Constitution and copyright protections afforded to humans as contrasted to artificial intelligence. As such, this paper will first establish some background on artificial in- telligence regarding how it is used to derive outputs under its human user’s direction. The ap- plicability of United States and Italian laws will also be briefly overviewed alongside the precautionary and innovation principles. An analytical comparison of United States and Italian Constitution and copyright provisions will provide the foundation for the above referenced four-part solution. Responses to possible counterarguments will also be addressed and rebutted.

Piedmont Health Collaborative Care Program

description: Depression presents a large burden of disease to the public. The lifetime and 12- month prevalence of depression in the United States ranges from 13-16%. Depression affects individuals throughout their lifetime with societal costs seen in families, employment, and health care. Furthermore, depression ranks among the leading global causes of disability. There is a reciprocal relationship between depression and physical illness, particularly diabetes. Diabetes affects approximately 12 percent of the U.S. population. Lifestyle changes, self-monitoring schedules, and treatments for diabetes present significant psychological and behavioral challenges for individuals with diabetes. Moreover, diabetics experiencing depression often have poorer health outcomes, more difficulty at home and at work, and higher health costs when compared to diabetics without depression. The care for these individuals generally occurs in primary care settings, prompting program planners to develop targeted depression screening programs for individuals with chronic medical illnesses, such as diabetes. Collaborative care programs within primary care grew from the realization that screening for depression alone would not achieve improvement in depression. These programs use mental health specialists within primary care to serve as consultants to care managers and primary care providers involved in depression screening efforts within their clinic population. The Piedmont Collaborative Care program occurs at the Carrboro Community Health Center in Carrboro, NC. The clinic cares for an underserved population, the majority of whom are Latino individuals. The program aims to improve the health of adults with poorly controlled diabetes. The program achieves improvements in health through better screening and treatment for depression.

description: The following paper will review a community-led movement that not only tangibly addresses core health concerns, but also tap into a larger community consciousness to create more systemic and comprehensive change within the population it serves. John Friedmann labels this genesis the "third system" which marks the collective potential we have as people to move towards and embrace "the humanization of man" (Friedmann, 1998). A review of the literature reveals that there little effort to address with skill such questions as, "What does the humanization of man, or women, really look like? Or, " How is there truly power in the people?" Global food and water shortages as well as a grossly unequal distribution of resources, causes one to wonder if individuals have any real power at all. Nevertheless, if indeed there is a "third system," a space that is "not a party or an organization," which serves as a framework for "human flourishing," where citizens are successfully changing social infrastructures; we need to see it alive and working. The following project, though not without flaws, will serve as an avenue to explore "human flourishing" in motion, and perhaps, offer us insight into how we as professionals can be part of the process.

description: Background Guidelines surrounding the medical treatment of type 1 diabetes are clear. They are less clear for managing the psychosocial effects of the disease. Research has shown that educational group interventions can be effective at improving glycemic control and psychosocial outcomes in this patient population. Photovoice could serve as a novel diabetes group intervention for improving psychosocial outcomes in adolescents with type 1 diabetes. Methods We conducted a pilot randomized controlled trial on 17 patients with type 1 diabetes aged 13-17 years to compare the effects of an online support group using photography to one not using photography on diabetes-specific psychosocial outcomes. These outcomes were assessed using the Diabetes Distress Scale, Diabetes Empowerment Scale-Short Form, and Diabetes Management Questionnaire. Feasibility and acceptability were also examined. Results An online support group program using photography is feasible and accepted by adolescents with type 1 diabetes. No improvements in diabetes-related distress, diabetes empowerment, or diabetes treatment adherence were seen when compared to an online support group using no photography. However, exploratory data suggest that this group intervention reduces regimen-related distress among participants 4 weeks post-intervention. Conclusions To our knowledge, this is the first study to examine the effects of an online Photovoice-based group intervention on diabetes-specific outcomes. More research is needed to demonstrate its efficacy on glycemic control and other diabetes-specific outcome measures.

description: Recently, West and Fong [New J. Phys. 14, 083002 (2012)] introduced an echo scheme for an exchange-only qubit, which relies entirely on the exchange-interaction. Here, we compare two different exchange-based sequences and two optimization strategies, Uhrig dynamical decoupling (UDD) and optimized filter function dynamical decoupling (OFDD), which were introduced for a single-spin qubit and are applied in this paper to the three-spin exchange-only qubit. The calculation shows that the adaption of the optimization concepts can be achieved by straight-forward calculation. We consider two types of noise spectra, Lorentzian and Ohmic noise. For both spectra, the results reveal a slight dependence of the performance on the choice of the echo sequence.

A Descriptive Analysis of Varicella Infections Among Patients Presenting to Emergency Departments in North Carolina
Creators: name: MacFarquhar, Jennifer K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Varicella, or chickenpox, is a highly communicable infectious disease which, in the prevaccine era, contributed to significant morbidity and mortality among the general population, as well as resulted in substantial costs to society. Following US vaccine licensure in 1995, a significant decline in disease, hospitalizations, and deaths began and has continued. The Healthy People 2010 goal related to varicella is disease reduction; in contrast, the goal of the CDC is disease elimination. State and national vaccination rates have steadily risen since 1995, with a current national rate of 85%. Although significant decreases in disease are evident and vaccination rates have increased, cases of disease, hospitalizations, and deaths still occur. Surveillance is a necessary component of vaccination programs in order to monitor impact, identify factors that allow cases to continue to occur, and to guide state policy. The Council of State and Territorial Epidemiologists (CSTE) recommended that each state institute an ongoing surveillance system to monitor the impact of varicella vaccination on the incidence of varicella by 2005. In response to this recommendation, North Carolina implemented a sentinel ED surveillance system. The system, although efficient, has limitations, but the resulting data demonstrate a low incidence of disease in the Emergency Department setting with minimal burden on North Carolina emergency healthcare systems.

Various phenomenological formulae with parameters for strong absorption radius Rs are obtained and compared by fitting the experimental data of quarter point angle extracted from nuclear elastic scattering reaction systems. The parameterized formula of Rs related to the isospin and binding energy is recommended, that gives a good reproduction of nuclear matter radii of halo nuclei.

description: We present a model for the $J/ψΛ$ spectrum in $B^-\to J/ψΛ\bar{p}$ decays, including the $P_{ψs}^Λ(4338)$ baryon recently observed by the LHCb collaboration. We assume production via triangle diagrams which couple to the final state via non-perturbative interactions which are constrained by heavy-quark and $SU_3$-flavor symmetry. The bulk of the distribution is described by a triangle diagram with a color-favored electroweak vertex, while the sharp $P_{ψs}^Λ(4338)$ enhancement is due to the triangle singularity in another diagram featuring a $1/2^-$ baryon consistent with $Σ_c(2800)$. We predict a comparable $P_{ψs}^Λ(4338)$ signal in $η_c Λ$, and anticipate possible large isospin mixing effects through decays to $J/ψΣ^0$ and $η_c Σ^0$

Year: 2006

description: Since the landmark report Oral Health in America: A Report of the Surgeon General 2000, the dental profession has responded with initiatives on many levels that address the need to reduce the barriers to oral health services and access to oral health to achieve improved oral health for all populations. The barriers are varied and range from public and professional rnisperceptions concerning the severity and susceptibility of across all populations to oral disease to complex social, biologic and environmental barriers which burden certain segments of the population disproportionately. The dental profession has used the core functions and essential services of public health to initiate a number of successful interventions that address these issues. Collaboration, leadership and education, key elements of the initiatives and core functions, have provided an ecological framework to increase capacity to serve, effectively identify and assign resources and achieve the goals and outcomes of the initiatives. Yet further work on these and related initiatives remains to be done. This paper highlights particular aspects of the core functions, essential services and leadership principles that helped achieve successful interventions in several key areas and proposes the continued expansion and use of the same to achieve progress in areas that lack momentum.

Außerdem wurden die Vor- und Nachteile von starken und schwachen Nukleophilen diskutiert.

 Besonderes Augenmerk wurde auf das sogenannte Weinrebamid gerichtet, ein Carbonsäureamid mit einer N-Methyl-N-methoxy-Gruppe, das sich durch eine relativ hohe Reaktivität gegenüber nukleophilem Angriff auszeichnet und ein stabiles Intermediat bildet, das für synthetische Zwecke von Nutzen ist. Andere, im Intermediat möglicherweise chelatisierungsfähige Carbonsäureamide, ähnlich dem Weinrebamid, bilden ebenfalls stabile Intermediate, erwiesen sich aber nicht als so reaktiv, während Benzoylderivate mit Pyridylresten außerordentlich reaktiv sind und sogar im Fall des N-Pyridylrests kein stabiles Intermediatbilden.

 Offensichtlich spielt die Absenkung der Aktivierungsenergie durch reaktivitätserhöhende Chelatisierung im Übergangszustand eine entscheidende Rolle bei der Ketonsynthese und nicht unbedingt die Stabilität des gebildeten Intermediats.

description: We investigate models of electrons in the Sachdev-Ye-Kitaev class with random and all-to-all electron hopping, electron spin exchange, and Cooper-pair hopping. An attractive on-site interaction between electrons leads to superconductivity at low temperatures. Depending on the relative strengths of the hopping and spin exchange, the normal state at the critical temperature is either a Fermi-liquid or a non-Fermi liquid. We present a large-$M$ (where spin symmetry is enlarged to SU$(M)$) study of the normal state to superconductor phase transition. We describe the transition temperature, the superconducting order parameter, and the electron spectral functions. We contrast between Fermi liquid and non-Fermi liquid normal states: we find that for weaker attractive on-site interaction there is a relative enhancement of $T_c$ when the normal state is a non-Fermi liquid, and correspondingly a strong deviation from BCS limit. Also, the phase transition in this case becomes a first-order transition for strong non-Fermi liquids. On the other hand, for stronger on-site interaction, there is no appreciable difference in $T_c$ between whether the superconductivity emerges from a Fermi liquid or a non-Fermi liquid. Notable features of superconductivity emerging from a non-Fermi liquid are that the superconducting electron spectral function is different from the Fermi-liquid case, with additional peaks at higher energies, and there is no Hebel-Slichter peak in the NMR relaxation rate in the non-Fermi liquid case.

Unsteadiness in hypersonic leading-edge separation

description: Hypersonic leading-edge separation is studied towards understanding the varying shock-related unsteadiness with freestream Reynolds number ($1.66 \times 10^5 \leq Re_D \leq 5.85 \times 10^5$) in the newly constructed hypersonic Ludwieg tunnel (HLT) at a freestream design Mach number of $M_\infty=6.0$. An axisymmetric flat-face cylinder of base body diameter $D=35$ mm is fitted with protrusions of different fineness ($d/D=0.1,0.2,0.26,0.34$ at $L/D=1.4$) and slenderness ($L/D=0.7,1,1.4,1.9$ at $d/D=0.2$) ratio to induce a wide range of leading-edge separation intensities. Qualitative and quantitative assessments are made using schlieren imaging, planar laser Rayleigh scattering, and unsteady pressure measurements. A well-known to-and-fro shock motion called pulsation and a flapping shock-shear layer oscillation is observed as $Re_D$ changes. A shorter protrusion length ($L/D=0.7$) produces a pressure loading that is four orders higher than the cases with longer protrusion lengths. There exists a critical separation length ($L/D \geq 1.4$) beyond which the separated shear layer trips to turbulence and introduces fluctuations in the recirculation region as $Re_D$ increases. The effect of the separated turbulent shear layer is dampened by an order provided the reattachment angle is shallow by increasing the fineness ratio ($d/D=0.4$). There also exists a critical geometrical parameter ($L/D=1, d/D=0.2$) for which the unsteady modes switch between successive runs based on the upstream fluctuations. From the modal analysis of the Rayleigh scattering images, the first four dominant modes that drive flapping are identified as translatory flapping, sinuous flapping, large and small-scale shedding.

description: To study the temperature in a gas subjected to electromagnetic radiations, one may use the Radiative Transfer equations coupled with the Navier-Stokes equations. The problem has 7 dimensions; however with minimal simplifications it is equivalent to a small number of integro-differential equations in 3 dimensions. We present the method and a numerical implementation using an H-matrix compression scheme. The result is a very fast: 50K physical points, all directions of radiation and 680 frequencies require less than 5 minutes on an Apple M1 Laptop. The method is capable of handling variable absorptioN and scattering functionS of spatial positions and frequencies. The implementation is done using htool, a matrix compression library interfaced with the PDE solver freefem++. Applications to the temperature in the French Chamonix valley is presented at different hours of the day with and without snow / clouds and with a variable absorption taken from the Gemini measurements. The result is precise enough to assert temperature differences due to increased absorption in the vibrational frequency subrange of greenhouse gasses.
The War on Heroin: A Prospective Analysis of Safe Injection Sites in King County, Washington

description: The rise in heroin overdose-related deaths among individuals with previous low rates of heroin use is unprecedented to such an extent it incites relatives of victims to petition for new approaches to reduce the death rates. In King County, Washington, officials, inspired by the impact of Insite, a safe injection site (SIS), on heroin crisis, in Vancouver, Canada, are considering implementing similar sites to provide a safe environment for heroin injection in King County. If implemented, these controversial sites will be the first to officially operate in United States. We attempt a better understanding of the proposed initiative by reviewing the scope of the heroin crisis in U.S., the effectiveness and efficiency of safe injection sites in Europe, Australia, and Canada where they are in effect. We also reviewed policies alternatives to SIS that address the heroin crisis in King County. This paper seeks to determine whether safe injection sites will fulfill its purpose, and whether they are better at reducing overdose death rates than other policies already implemented in King County.
Interventions in the Delivery of Outpatient Diabetes Care: A systematic review of the literature 2001-2005

description: CONTEXT: Current practices of outpatient care for type 2 diabetes are not producing adequate patient-oriented outcomes according to the targets established by clinical research trials. OBJECTIVE: To systematically review the best evidence available about the care of diabetes in the outpatient setting. METHODS: The author searched both the PubMed and CINAHL databases for reports of randomized controlled trials and systematic reviews published in English between 2001-2005 that matched the MeSH terms "diabetes" and "outpatient". Articles were then narrowed based on both relevance and quality. Included studies reported patient-oriented outcomes (blood pressure, percent hemoglobin A1c, or blood lipid levels). Interventions were divided into those affecting the setting of care, affecting the process of care, or involving primarily education. RESULTS: Of441 identified articles, 19 met all criteria and were included. Intensive process interventions were effective and generally involved multifaceted case management. Educational interventions were effective in the short term, but benefits did not extend beyond the intervention term for any study. Setting interventions showed no significant benefit. CONCLUSIONS: The literature on this topic is still inconclusive and heterogeneous. The few interventions that showed benefit are highly resource-intensive, and for this reason have significant threats to broad applicability. Successful process interventions require cost-benefit studies to determine their widespread feasibility in varied settings. Neither setting nor education interventions show physiological benefits that justify their cost.
