description: We theoretically investigate the superfluid phase transition of helium-3 under nanoscale confinement of one spatial dimension realized in recent experiments. Instead of the 3x3 complex matrix order parameter found in the three-dimensional system, the quasi two-dimensional superfluid is described by a reduced 3x2 complex matrix. It features a nodal quasiparticle spectrum, regardless of the value of the order parameter. The origin of the 3x2 order parameter is first illustrated via the two-particle Cooper problem, where Cooper pairs in the $p_x$ and $p_y$ orbitals are shown to have a lower bound state energy than those in $p_z$ orbitals, hinting at their energetically favorable role at the phase transition. We then compute the Landau free energy under confinement within the mean-field approximation and show that the critical temperature for condensation of the 3x2 order parameter is larger than for other competing phases. Through exact minimization of the mean-field free energy, we show that mean-field theory predicts precisely two energetically degenerate superfluid orders to emerge at the transition that are not related by symmetry: the A-phase and the planar phase. Beyond the mean-field approximation, we show that strong-coupling corrections favor the A-phase observed in experiment, whereas weak-coupling perturbative renormalization group predicts the planar phase to be stable.

Childhood and Adolescent Obesity: Understanding the U.S. Epidemic
Creators: name: Warden, Beverly A.

description: Childhood obesity is the latest U.S. epidemic to come to the attention of the public health community. According to numerous recent studies, in the last 20 years, obesity rates have doubled for children and tripled for adolescents. In addition, for children aged 2- 17, studies have reported an increase in the average weight. Statistics indicate that the risk of overweight or obesity in children and adolescents is directly related to minority status and poverty. The reasons for these increases are still under investigation. Causes of obesity may include: genetics/family history, soft drink consumption, sedentary lifestyle, and fast food consumption. The detrimental effects on young people run the gamut from physiological effects (e.g. type 2 diabetes, cardiovascular disease, arthritic problems) to psychological effects (e.g. low self esteem, depression). Even more concerning is the potential for a decreased life span in this population at a time when technology and advanced health care techniques have the capacity to improve the quality oflife and increase longevity. Strategies for treatment and prevention are still being tested in an attempt to halt the epidemic. However, research on strategies for preventing and treating overweight in children has produced inconclusive results. In fact, the majority of treatment studies involving diet and exercise found no differences between treatment and control groups. Prevention research has focused on both primary and secondary prevention techniques which include promoting: breastfeeding, increased physical activity, reduced sedentary behaviors, increased fruit and vegetable consumption, reduced consumption of sugar-sweetened drinks, and reduced portion sizes none of which have been shown to have unequivocal success. For further progress to be made in stemming the tide of childhood and adolescent overweight and obesity, policies need to be implemented that address the need for scientific data to identifY effective treatment and prevention strategies. However, it is unlikely that these policies will be enacted along with the funding necessary to address these research needs until childhood obesity is a high priority on the public agenda. This paper reviews the current literature on the problem, causes, health outcomes, treatment, and prevention strategies associated with childhood overweight and obesity along with presenting a study ofU.S. population data, and a summary of policy issues related to the epidemic.

description: We carry out large-scale micromagnetic simulations which demonstrate that due to topological constraints, internal domain walls (Bloch lines) within extended domain walls are more robust than domain walls in nanowires. Thus, the possibility of spintronics applications based on their motion channeled along domain walls emerges. Internal domain walls are nucleated within domain walls in perpendicularly magnetized media concurrent with a Walker breakdown-like abrupt reduction of the domain wall velocity above a threshold driving force, and may also be generated within pinned, localized domain walls. We observe fast field and current driven internal domain wall dynamics without a Walker breakdown along pinned domain walls, originating from topological protection of the internal domain wall structure due to the surrounding out-of-plane domains.

Beyond Legislation: The relationship between physician and clinical site characteristics, organizational citizenship behaviors and intended retention of National Health Service Corps physicians in the late 1990's
Creators: name: Campion, Ashley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Objective: 1) To evaluate the relationship between National Health Service Corps (NHSC) physicians' participation in Organizational Citizenship Behaviors (OCBs) and their intention to stay at their assigned site or serve the underserved post obligation. 2) To examine the relationship between NHSC physician and site characteristics and NHSC physicians' participation in OCBs. Design: Secondary analysis of a cross-sectional observational study. Source of Study Data: Thomas R. Konrad, of the Sheps Center at UNC-CH, and colleagues at Mathematica Policy Research collected the data as part of An Evaluation of the Effectiveness of the National Health Service Corps, 1 a project performed for the Health Services Resource Administration in 1998. The data come from a nationally representative survey of NHSC clinicians serving part of their NHSC obligation on December 31, 1997. Sample: 387 NHSC physicians, stratified by Scholarship/Loan Repayment NHSC program and by whether they served their NHSC obligation in an urban or a rural community. The sample included 55 urban scholars, 104 urban loan repayors, 105 rural scholars, and 123 rural loan repayors. Findings: 1) NHSC physician participation in OCBs (above and beyond behaviors) is significantly associated with physician intention to stay at his/her NHSC assigned site for one year post obligation (p<.001) and with physician intention to serve the underserved for at least four years post obligation (p= .014), but not significantly associated with intention to stay at his/her NHSC assigned site for four years post obligation (p=.191 ). 2) Physicians with higher educational debt are involved in significantly more OCBs (p= .023). Scholars serving in rural areas participate in significantly more OCBs than do scholars or loan repayors serving in urban areas. Service in federally funded clinics and service at clinics with more full time providers are associated with performing fewer OCBs, but higher salaries, longer service, and family satisfaction with the community are associated with performing more OCBs Conclusions: Participating in OCBs is correlated with intention to stay at the NHSC site and with a commitment to continue serving the underserved. Physician and site characteristics that promote OCB participation suggest domains for intervening to encourage more physician engagement.

description: GJ 367 is a bright (V $\approx$ 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of improving the planetary mass and radius and unveiling the inner architecture of the system, we performed an intensive radial velocity follow-up campaign with the HARPS spectrograph -- collecting 371 high-precision measurements over a baseline of nearly 3 years -- and combined our Doppler measurements with new TESS observations from sectors 35 and 36. We found that GJ 367 b has a mass of $M_\mathrm{b}$ = 0.633 $\pm$ 0.050 M$_{\oplus}$ and a radius of $R_\mathrm{b}$ = 0.699 $\pm$ 0.024 R$_{\oplus}$, corresponding to precisions of 8% and 3.4%, respectively. This implies a planetary bulk density of $ρ_\mathrm{b}$ = 10.2 $\pm$ 1.3 g cm$^{-3}$, i.e., 85% higher than Earth's density. We revealed the presence of two additional non transiting low-mass companions with orbital periods of $\sim$11.5 and 34 days and minimum masses of $M_\mathrm{c}\sin{i_\mathrm{c}}$ = 4.13 $\pm$ 0.36 M$_{\oplus}$ and $M_\mathrm{d}\sin{i_\mathrm{d}}$ = 6.03 $\pm$ 0.49 M$_{\oplus}$, respectively, which lie close to the 3:1 mean motion commensurability. GJ 367 b joins the small class of high-density planets, namely the class of super-Mercuries, being the densest ultra-short period small planet known to date. Thanks to our precise mass and radius estimates, we explored the potential internal composition and structure of GJ 367 b, and found that it is expected to have an iron core with a mass fraction of 0.91$^{+0.07}_{-0.23}$. How this iron core is formed and how such a high density is reached is still not clear, and we discuss the possible pathways of formation of such a small ultra-dense planet.

description: The beta spectrum of the main transition of the beta-decay of 171Tm was measured using a double focalizing spectrometer. The instrument was lately improved in order to reduce its low energy threshold to 34 keV. We used the spectrometer to measure the beta spectrum end-point energy of the main transition of 171Tm decay using the Kurie plot formalism. We report a new value of 97.60(38) keV, which is in agreement with previous measurements. In addition, the spectrum shape was compared with the xi-approximation calculation where the shape factor is equal to 1 and good agreement was found between the theory and the measurement at the 1% level.

description: Abstract: Healthy People 2010 has an important goal of having 95% of children enrolled in an immunization registry by age two. This paper examines the importance of vaccines, safety issues with vaccines, the importance of having a useful immunization registry, benefits and current limitations of vaccine registries, as well as suggestions on how to improve current registries, including how to ensure future expandability and usefulness. I conducted a meta-analysis of existing research on the topic of immunization registries, vaccine importance, and vaccine safety, as well as used my own practicum experience implementing the North Carolina Immunization Registry into hospital nurseries across the state. My research found that while immunization registry use has increased dramatically within the past decade, there are still stumbling blocks and problems that need to be addressed, but the benefits of a working registry greatly outweigh any limitations. Finally, I offer suggestions of how some of the major limitations can be addressed.

description: The purpose of this thesis was to systematically investigate the factors that enhance and compromise the lives of Huntington's Disease (HD) spousal carers by utilising the theoretical construct of quality of life (QoL). Three exploratory studies provided evidence that spousal carers of I-ID patients have specific difficulties in maintaining their QoL whilst continuing in a primary care-giving role. Study 1 provided preliminary evidence that spousal carers of I-ID patients and health care professionals would value a disease specific QoL scale that could be used to evaluate spousal carers' objective and subjective QoL. Study 2 established that spousal carers of I-ID patients often experience loneliness, a need to escape and a unique sense of loss whilst trying to adequately care for their loved ones and maintain some form of QoL for themselves. Study 3 provided further evidence that QoL is compromised in many ways and is an issue for I-ID carers. The carers in this study often neglected their own needs as the care giving role and disease processes 'took over' their lives as well as the life of their I-ID affected spouse. The findings of these three studies prepared the way for the development of a disease-specific QoL measure for spousal carers of lID patients. Validation of the Huntington's Disease Quality of Life Battery for Carers(HDQoL-G was carried out in study 4. The newly developed scale was found to have good internal consistency, test-retest and face validity. It is hoped that the HDQoL-C will be used in the future to quantify the caregiving experience in I-ID in order to implement and assess therapeutic interventions.

description: An election audit is risk-limiting if the audit limits (to a pre-specified threshold) the chance that an erroneous electoral outcome will be certified. Extant methods for auditing instant-runoff voting (IRV) elections are either not risk-limiting or require cast vote records (CVRs), the voting system's electronic record of the votes on each ballot. CVRs are not always available, for instance, in jurisdictions that tabulate IRV contests manually. We develop an RLA method (AWAIRE) that uses adaptively weighted averages of test supermartingales to efficiently audit IRV elections when CVRs are not available. The adaptive weighting 'learns' an efficient set of hypotheses to test to confirm the election outcome. When accurate CVRs are available, AWAIRE can use them to increase the efficiency to match the performance of existing methods that require CVRs. We provide an open-source prototype implementation that can handle elections with up to six candidates. Simulations using data from real elections show that AWAIRE is likely to be efficient in practice. We discuss how to extend the computational approach to handle elections with more candidates. Adaptively weighted averages of test supermartingales are a general tool, useful beyond election audits to test collections of hypotheses sequentially while rigorously controlling the familywise error rate.

description: Isolated magnetic skyrmions are stable, topologically protected spin textures that are at the forefront of research interests today due to their potential applications in information technology. A distinct class of skyrmion hosts are rare earth - transition metal (RE-TM) ferrimagnetic materials. To date, the nature and the control of basic traits of skyrmions in these materials are not fully understood. We show that for an archetypal ferrimagnetic material DyCo$_3$ that exhibits a strong perpendicular anisotropy, the ferrimagnetic skyrmion size can be tuned by an external magnetic field. Moreover, by taking advantage of the high spatial resolution of scanning transmission X-ray microscopy (STXM) and utilizing a large x-ray magnetic linear dichroism (XMLD) contrast that occurs naturally at the RE resonant edges, we resolve the nature of the magnetic domain walls of ferrimagnetic skyrmions. We demonstrate that through this method one can easily discriminate between Bloch and Néel type domain walls for each individual skyrmion. For all isolated ferrimagnetic skyrmions, we observe that the domain walls are of Néel-type. This key information is corroborated with results of micromagnetic simulations and allows us to conclude on the nature of the Dzyaloshinskii-Moriya interaction (DMI) which concurs to the stabilisation of skyrmions in this ferrimagnetic system. Establishing that an intrinsic DMI occurs in RE-TM materials will also be beneficial towards a deeper understanding of chiral spin texture control in ferrimagnetic materials.

description: For a resonance decaying to $τ^+τ^-$, it is difficult to reconstruct its mass accurately because of the presence of neutrinos in the decay products of the $τ$ leptons. If the resonance is heavy enough, we show that its mass can be well determined by the momentum component of the $τ$ decay products perpendicular to the velocity of the $τ$ lepton, $p_{\perp}$, and the mass of the visible/invisible decay products, $m_{vis/inv}$, for $τ$ decaying to hadrons/leptons. By sampling all kinematically allowed values of $p_{\perp}$ and $m_{vis/inv}$ according to their joint probability distributions determined by the MC simulations, the mass of the mother resonance is assumed to lie at the position with the maximal probability. Since $p_{\perp}$ and $m_{vis/inv}$ are invariant under the boost in the $τ$ lepton direction, the joint probability distributions are independent upon $τ$'s origin. Thus this technique is able to determine the mass of an unknown resonance with no efficiency loss. It is tested using the MC simulations of the physics processes $ pp \to Z/h(125)/h(750)+X\to ττ+X$ at 13~TeV. The ratio of the full width at half maximum and the peak value of the reconstructed mass distribution is found to be 20\%-40\% using the information of missing transverse energy.

description: Hyperspectral imaging (HSI) captures a greater level of spectral detail than traditional optical imaging, making it a potentially valuable intraoperative tool when precise tissue differentiation is essential. Hardware limitations of current optical systems used for handheld real-time video HSI result in a limited focal depth, thereby posing usability issues for integration of the technology into the operating room. This work integrates a focus-tunable liquid lens into a video HSI exoscope, and proposes novel video autofocusing methods based on deep reinforcement learning. A first-of-its-kind robotic focal-time scan was performed to create a realistic and reproducible testing dataset. We benchmarked our proposed autofocus algorithm against traditional policies, and found our novel approach to perform significantly ($p<0.05$) better than traditional techniques ($0.070\pm.098$ mean absolute focal error compared to $0.146\pm.148$). In addition, we performed a blinded usability trial by having two neurosurgeons compare the system with different autofocus policies, and found our novel approach to be the most favourable, making our system a desirable addition for intraoperative HSI.

description: The Galois ring GR$(4^Δ)$ is the residue ring $Z_4[x]/(h(x))$, where $h(x)$ is a basic primitive polynomial of degree $Δ$ over $Z_4$. For any odd $Δ$ larger than $1$, we construct a partition of GR$(4^Δ) \backslash \{0\}$ into $6$-subsets of type $\{a,b,-a-b,-a,-b,a+b\}$ and $3$-subsets of type $\{c,-c,2c\}$ such that the partition is invariant under the multiplication by a nonzero element of the Teichmuller set in GR$(4^Δ)$ and, if $Δ$ is not a multiple of $3$, under the action of the automorphism group of GR$(4^Δ)$. As a corollary, this implies the existence of quasi-cyclic additive $1$-perfect codes of index $(2^Δ-1)$ in $D((2^Δ-1)(2^Δ-2)/{6}, 2^Δ-1 )$ where $D(m,n)$ is the Doob metric scheme on $Z^{2m+n}$.

description: Equations of a rotating body with one point constrained to move freely on a plane (dancing top) are deduced from the Lagrangian variational problem. They formally look like the Euler-Poisson equations of a heavy body with fixed point, immersed in a fictitious gravity field. Using this analogy, we have found examples of analytical solutions for the case of a heavy symmetrical dancing top. They describe the motions with center of mass keeping its height fixed above the supporting plane. General solution to equations of a dancing top in terms of exponential of Hamiltonian field is given. An extra constraint, that take into account the reaction of supporting plane, leads to modification of the canonical Poisson structure and therefore the integrability according to Liouville is under the question.

description: Recently Tsuji & Nakajima (2914) and Tsuji, Nakajima & Takeda (2015) have developed a method of molecular line spectroscopy of M dwarfs with which Carbon and oxygen abundances are derived respectively from CO and H2O lines in the K band. They applied this method to Gl229A, the primary star of the brown dwarf companion, Gl229B. The derived abundances of Gl229A are logAc=-3.27+/-0.07 and logAo=-3.10+/-0.02, which are close to the classical values of the solar abundances of carbon and oxygen. We generate model spectra of Gl229B for the metallicity of Gl229A as well as for the classical solar metallicity. We find that the differences of the resulting spectra are not so large for the differences of the metallicity of 0.1 dex or so, but we now discuss the spectrum of Gl229B on the basis of the reliable metallicity. From the literature, the lower limit to the age of Gl229A is found to be 0.3Gyr. From the kinematics of Gl229A, we evaluate the upper limit to the age of Gl229A to be 3.0Gyr. The observed and model spectra are compared and goodness of fit is obtained in the range of model parameters, 750

description: This paper presents a new framework to measure farm-level heterogeneity, and productivity change, and to study the rate and direction of technical change within an agricultural sector. Building on the seminal works of Hildenbrand (1981) and Dosi et al. (2016), we show how, while relaxing most of the standard assumptions from production theory, discrete geometry is an effective tool for productivity analysis and technical change in agricultural economics. We apply the framework to a rich panel data from maize farmers in Tanzania to investigate the dynamics of technical heterogeneity and agricultural productivity growth.

description: In this work, we investigate laparoscopic camera motion automation through imitation learning from retrospective videos of laparoscopic interventions. A novel method is introduced that learns to augment a surgeon's behavior in image space through object motion invariant image registration via homographies. Contrary to existing approaches, no geometric assumptions are made and no depth information is necessary, enabling immediate translation to a robotic setup. Deviating from the dominant approach in the literature which consist of following a surgical tool, we do not handcraft the objective and no priors are imposed on the surgical scene, allowing the method to discover unbiased policies. In this new research field, significant improvements are demonstrated over two baselines on the Cholec80 and HeiChole datasets, showcasing an improvement of 47% over camera motion continuation. The method is further shown to indeed predict camera motion correctly on the public motion classification labels of the AutoLaparo dataset. All code is made accessible on GitHub.

Objective information in the empiricist view of von Weizsäcker

description: We analyze von Weizsäcker view regarding the concept of information in physics. In his view, information arises from the reduction of properties of a physical object to their logical descriptive propositions. The smallest element of a lattice of propositions is an atom of information which is considered as the essence of every physical identity including position space. von Weizsäcker calls this element, ur. Moreover, Biological evolution is described in terms of enhancement of the variety of forms. Form could be also reduced to descriptive logical propositions, thus to atoms of information. Therefore, information is the fundamental basis in von Weizsäcker plan for unifying all branches of Physics including Chemistry and Biology. Yet, there are inadequacies in his lines of reasoning, critically assessed in this paper.
Violence, Alcohol, and Traumatic Brain Injuries: Retrospective analysis of assault data from the University of North Carolina Hospitals and Kamuzu Central Hospital of Lilongwe, Malawi
Creators: name: Meyerhoff, Karen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Alcohol use is associated with interpersonal violence, and head injuries are often the result. Past studies have suggested that acute alcohol use prior to traumatic brain injury (TBI) could decrease patient mortality, without focus on specific causes of TBIs. We compared victims of interpersonal violence from two different global settings (a developed vs a developing nation) to identify commonalities in risk factors and patterns of injury and test the association between acute alcohol use and mortality in this specific population. Results: In both populations (from the University of North Carolina (UNC) and those from Kamuzu Central Hospital in Lilongwe, Malawi), victims were more likely to be younger, male, and have a head and/or face injury. Only two thirds of the UNC patients were tested for blood alcohol levels on admission, but approximately half of those tested positive. From history of self-report, only a third of the Malawian assault victims had used alcohol acutely. When UNC and Malawi patient groups were combined, alcohol use was found to be associated with a decreased mortality for all assault victims. For patients with possible traumatic brain injuries, alcohol was found to be associated with a lower mortality rate in the UNC cohort but not in the Malawian cohort (unadjusted). Conclusions: Despite many differences in background and setting, assault victims from both UNC and Malawi were very similar in respect to age, gender, and type of injury. Alcohol use was seen to be associated with a decreased mortality for patients in both cohorts regardless of injury type, but further conclusions about its protective effects on mortality cannot be drawn due to limitations of this retrospective analysis. Alcohol is highly correlated with head injuries in both UNC and Malawian cohorts, so investigation into its availability in both settings could help aid in injury prevention strategies globally.
Evolution of the wave-function's shape in a time-dependent harmonic potential

description: An effective operational approach to quantum mechanics is to focus on the evolution of wave-packets, for which the wave-function can be seen in the semi-classical regime as representing a classical motion dressed with extra degrees of freedom describing the shape of the wave-packet and its fluctuations. These quantum dressing are independent degrees of freedom, mathematically encoded in the higher moments of the wave-function. We review how to extract the effective dynamics for Gaussian wave-packets evolving according to the Schrodinger equation with time-dependent potential in a 1+1-dimensional spacetime, and derive the equations of motion for the quadratic uncertainty. We then show how to integrate the evolution of all the higher moments for a general wave-function in a time-dependent harmonic potential.

Modeling the complexity of Elliptic Black Hole Solution In 4D Using Hamiltonian Monte Carlo with Stacked Neural Networks

description: In this paper, we study the black hole solution of self-similar gravitational collapse in the Einstein-axion-dilaton system for the elliptic class in four dimensions. The solution is invariant under space-time dilation, which is combined with internal SL(2,R) transformations. Due to the complex and highly nonlinear pattern of the equations of motion in the physics of black holes, researchers typically have to use various numerical techniques to make the equations tractable to estimate the parameters and the critical solutions. To this end, they have to ignore the numerical measurement errors in estimating the parameters. To our knowledge, for the first time in the literature on axion-dilation systems, we propose to estimate the critical collapse functions in a Bayesian framework. We develop a novel methodology to translate the modelling of the complexity of the elliptic black hole to a sampling problem using Hamiltonian Monte Carlo with stacked neural networks. Unlike methods in the literature, this probabilistic approach enables us not only to recover the available deterministic solution but also to explore possibly all physically distinguishable self-similar solutions that may occur due to numerical measurement errors.

description: Observations of the microwave background fluctuations suggest a scale-dependent amplitude asymmetry of roughly 2.5 sigma significance. Inflationary explanations for this 'anomaly' require non-Gaussian fluctuations which couple observable modes to those on much larger scales. In this Letter we describe an analysis of such scenarios which significantly extends previous treatments. We identify the non-Gaussian 'response function' which characterizes the asymmetry, and show that it is non-trivial to construct a model which yields a sufficient amplitude: many independent fine tunings are required, often making such models appear less likely than the anomaly they seek to explain. We present an explicit model satisfying observational constraints and determine for the first time how large its bispectrum would appear to a Planck-like experiment. Although this model is merely illustrative, we expect it is a good proxy for the bispectrum in a sizeable class of models which generate a scale-dependent response using a large eta parameter.
