description: Energy spectra both of the conduction and valence bands of the HgTe quantum wells with a width close to the Dirac point were studied experimentally. Simultaneous analysis of the Shubnikov-de Haas oscillations and Hall effect over a wide range of electron and hole densities gives surprising result: the top of the valence band is strongly split by spin-orbit interaction while the splitting of the conduction band is absent, within experimental accuracy. Astonishingly, but such a ratio of the splitting values is observed as for structures with normal spectrum so for structures with inverted one. These results do not consistent with the results of kP calculations, in which the smooth electric filed across the quantum well is only reckoned in. It is shown that taking into account the asymmetry of the quantum well interfaces within a tight-binding method gives reasonable agreement with the experimental data.

Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: Objective: To test whether periodontal intervention in dialysis patients with periodontal disease will result in improvement of inflammatory and metabolic markers compared to no treatment. Methods: Fifty-one dialysis patients with moderate to severe periodontal disease were recruited from six dialysis units. Twenty-five subjects were randomized to a periodontal treatment arm and twenty-six subjects were randomized to a control arm. Clinical periodontal parameters and serum were collected at baseline, 3 months and 6 months. Serum was analyzed for interleukin-6 and serum albumin. Results: Compared to untreated control, periodontal therapy was associated with a statistically significant improvement in clinical parameters of periodontal disease at 3 months, but not at 6 months and was not associated with any difference in serum interleukin-6 or serum albumin. Conclusion: Periodontal therapy was associated with improved clinical measures of periodontal disease, but not with improved interleukin-6 or serum albumin in this population. Diabetic status, plaque control and obesity should be tightly controlled in future studies of periodontal therapy in this population.

description: The family of organic-inorganic halide perovskite materials has generated tremendous interest in the field of photovoltaics due to their high power conversion efficiencies. There has been intensive development of cells based on the archetypal methylammonium (MA)and recently introduced formamidinium (FA) materials, however, there is still considerable controversy over their fundamental electronic properties. Two of the most important parameters are the binding energy of the exciton (R$^{*}$) and its reduced effective mass $μ$. Here we present extensive magneto optical studies of Cl assisted grown MAPbI$_{3}$ as well as MAPbBr$_{3}$ and the FA based materials FAPbI$_{3}$ and FAPbBr$_{3}$. We fit the excitonic states as a hydrogenic atom in magnetic field and the Landau levels for free carriers to give R$^{*}$ and $μ$. The values of the exciton binding energy are in the range 14 - 25 meV in the low temperature phase and fall considerably at higher temperatures for the tri-iodides, consistent with free carrier behaviour in all devices made from these materials. Both R$^{*}$ and $μ$ increase approximately proportionally to the band gap, and the mass values, 0.09-0.117 m$_{0}$, are consistent with a simple \textbf{k.p} perturbation approach to the band structure which can be generalized to predict values for the effective mass and binding energy for other members of this perovskite family of materials.

description: This thesis explores the impact of strategic culture on the United States Navy's reaction to the dreadnought and battlecruiser ship types introduced by the British Navy under Admiral Fisher. This essay concludes that the strategic culture of the U.S. Navy, shaped in large part by Alfred Thayer Mahan, was unable to adapt to the new environment suggested by Fisher's ships. While the U.S. Navy adopted dreadnoughts, its leaders and thinkers were unable to grasp the battlecruiser concept, and decided against building them.

description: One of Feynman's greatest contributions to physics was the interpretation of negative energies as antimatter in quantum field theory. A key component of this interpretation is the Feynman propagator, which seeks to describe the behavior of antimatter at the virtual particle level. Ironically, it turns out that one can dispense with the Feynman propagator in a direct-action theory of fields, while still retaining the interpretation of negative energy solutions as antiparticles.

Seeking Harmonization: Measuring the Effectiveness of the Common European Asylum System
Creators: name: Sampson, Drew Alan
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This thesis is an examination of the effectiveness of the European Union's efforts to create a unified asylum system. For over two decades, the EU has been taking action to ensure the upholding of human rights; create an efficient system via the fusion of national systems and implementation of EU institutions and instruments; and to better integrate immigrants. While there have been many new developments in the last decade alone, this thesis observes continuing human rights violations, insufficient coherency in the between member states, and a lacking effort to truly integrate migrants. In conclusion, this thesis advises that greater oversight and enforcement, more binding directives, and increased efforts made directly by the EU to integrate migrants are all necessary actions which could alleviate burden disparities and foster a more effective, efficient, and coherent common system of asylum.

description: A hybridized discontinuous Galerkin method is proposed for solving 2D fractional convection-diffusion equations containing derivatives of fractional order in space on a finite domain. The Riemann-Liouville derivative is used for the spatial derivative. Combining the characteristic method and the hybridized discontinuous Galerkin method, the symmetric variational formulation is constructed. The stability of the presented scheme is proved. Theoretically, the order of $\mathcal{O}(h^{k+1/2}+Δt)$ is established for the corresponding models and numerically the better convergence rates are detected by carefully choosing the numerical fluxes. Extensive numerical experiments are performed to illustrate the performance of the proposed schemes. The first numerical example is to display the convergence orders, while the second one justifies the benefits of the schemes. Both are tested with triangular meshes.

An Investigation of the Role of Metacognitive Behavior in Self-Regulated-Learning When Learning a Complex Science Topic with a Hypermedia Learning Environment
Creators: name: Binbasaran Tuysuzoglu, Banu
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Studies have shown that learners need to use self-regulated learning (SRL) skills when learning with Hypermedia Learning Environments (HLEs) to reach a conceptual understanding of science. SRL theory suggests that metacognition plays a key role in learning. The aim of this study was to investigate the relationship between metacognitive monitoring (e.g., judgment of learning [JOL]) and metacognitive control and their effects upon learning about the circulatory system with an HLE. I examined the frequencies of learners' use of negative JOL with and without a change in strategy use, which indicates the quality (i.e., static or adaptive) of metacognitive behavior. The results showed that adaptive metacognitive behavior positively related to learning, and static metacognitive behavior negatively related to learning, above and beyond the effect of prior knowledge. Findings provided valuable implications for the benefits of using JOL followed by control over strategy use when learning with HLEs.

Tobe can take the form of a tangible avatar displaying live physiological readings to reflect on ourselves and others. Such a toolkit could be used by researchers and designers to create a multitude of potential tangible applications, including (but not limited to) educational tools about Science Technologies Engineering and Mathematics (STEM) and cognitive science, medical applications or entertainment and social experiences with one or several users or Tobes involved. Through a co-design approach, we investigated how everyday people picture their physiology and we validated the acceptability of Tobe in a scientific museum. We also give a practical example where two users relax together, with insights on how Tobe helped them to synchronize their signals and share a moment.

Sacred Earth: the evolution of the Catholic Church's teaching on care for creation and how ordinary Catholics are hearing the call
Creators: name: Read, Sheila
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Since the mid-twentieth century, the widespread environmental degradation caused by humans' exploitation of the Earth has attracted increased attention. Environmentalists, scholars and theologians have blamed both Christianity and the scientific-industrial mindset for emphasizing an anthropocentric view that sees the Earth as here to fulfill human needs. In the last 20 years, within Christianity, including the Catholic Church, has been a growing recognition that environmental destruction is a sin, which has led to the birth of a creation care movement. This thesis explores the evolution in the Catholic Church's public teaching on human responsibility to include caring for the Earth. It looks at how some Catholic communities are responding with innovative projects to the pope's call to care for the Earth. The thesis also explores the extent to which ordinary Catholics are hearing the call to change their lifestyles and the barriers that affect church leaders' communication of the message.

description: Graphene nanoribbon quantum dot qubits have been proposed as promising candidates for quantum computing applications to overcome the spin-decoherence problems associated with typical semiconductor (e.g. GaAs) quantum dot qubits. We perform theoretical studies of the electronic structures of graphene nanoribbon quantum dots by solving the Dirac equation with appropriate boundary conditions. We then evaluate the exchange splitting based on an unrestricted Hartree-Fock method for the Dirac particles. The electronic wave function and long-range exchange coupling due to the Klein tunneling and the Coulomb interaction are calculated for various gate configurations. It is found that the exchange coupling between qubits can be significantly enhanced by the Klein tunneling effect. The implications of our results for practical qubit construction and operation are discussed.

description: This contribution reviews the present status of the Skyrme-Hartree-Fock (SHF) approach as one of the leading self-consistent mean-field models in the physics of atomic nuclei. It starts with a brief summary of the formalism and strategy for proper calibration of the SHF functional. The main emphasis lies on an exploration of the reliability of predictions, particularly in the regime of extrapolations. Various strategies are discussed to explore the statistical and systematic errors of SHF. The strategies are illustrated on examples from actual applications. Variations of model and fit data are used to get an idea about systematic errors. The statistical error is evaluated in straightforward manner by statistical analysis based on $χ^2$ fits. This also allows also to evaluate the correlations (covariances) between observables which provides useful insights into the structure of the model and of the fitting strategy.

A Pilot Study of Students’ Self-Perceptions of Efficacy and Engagement in the Writing Process
Creators: name: Hutchison, Leigh Anna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: This pilot study used a descriptive case-study method, with multiple cases, to examine changes in students’ self-perceptions and performance in writing. The study focused on the effects of an intervention, intended to impact components of motivational engagement (interest and writing apprehension) as well as self-efficacy beliefs, for students with cognitive strengths and learning deficits, in order to determine how this relates to levels of effort and persistence on writing tasks. The participants were two adolescent students, who exhibited cognitive strengths, coupled with learning disabilities in writing. The study design used Entry Phase and Exit Phase measures to collect data on the students’ levels of self-efficacy, apprehension, and interest in writing, before and after the intervention. Additional measures of effort, persistence, and performance were also taken at Entry and Exit Phases. Findings indicated improvements for both students on levels of effort, persistence, and performance following the intervention.

description: We derive the off-shell Noether current and potential in the context of Horndeski theory, which is the most general scalar-tensor theory with a Lagrangian containing derivatives up to second order while yielding at most to second-order equations of motion in four dimensions. Then the formulation of conserved charges is proposed on basis of the off-shell Noether potential and the surface term got from the variation of the Lagrangian. As an application, we calculate the conserved charges of black holes in a scalar-tensor theory with non-minimal coupling between derivatives of the scalar field and the Einstein tensor.

Impact of ordering competition on the global phase diagram of iron pnictides

Publisher: name: arXiv
Year: 2015

description: We consider the impact of the competition among superconductivity, spin density wave, and nematic order in iron pnictides, and show that the ordering competition substantially reshapes the global phase diagram. We perform a detailed renormalization group analysis of an effective field theory of iron pnictides and derive the flow equations of all the physical parameters. Using these results, we find that superconductivity can be strongly suppressed by the ordering competition, and also extract the $T$-dependence of superfluid density. Moreover, the phase transitions may become first order. Interestingly, our RG analysis reveal that the nematic order exists only in an intermediate temperature region $T_{m}< T < T_{n}$, but is destroyed at $T > T_{n}$ by thermal fluctuation and at $T < T_{m}$ by ordering competition. This anomalous existence of nematic order leads to a back-bending of the nematic transition line on the phase diagram, consistent with the observed reentrance of tetragonal structure at low temperatures. A modified phase diagram is obtained based on the RG results.

The effects of functional ankle instability and induced fatigue on ankle stiffness
Creators: name: Kuenze, Christopher
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Objective: To investigate effects of fatigue and functional ankle instability on ankle stiffness. Design: Repeated measures pre-fatigue, post-fatigue measurement of ankle stiffness in stable and functionally unstable ankles. Subjects: Forty subjects (14 men and 26 women, age = 21.7 ± 2.5 years, weight = 173.3 ± 11.0 kilograms, height = 74.7 ± 20.9 centimeters) assigned to stable ankle and functionally unstable ankle groups. Statistical Analysis: Three 2 (stable, functionally unstable) x 2 (pre-fatigue, post-fatigue) mixed model repeated measures ANOVAs. Main Outcome Measure(s): Ankle stiffness, peroneus longus EMG pre-activation, and peroneus longus mean EMG amplitude. Results: No significant differences in ankle stiffness and significant decreases in EMG pre-activation and mean EMG amplitude post-fatigue. Significance: Fatigue alters EMG pre-activation and EMG amplitude but the effect on ankle stiffness remain unclear due to lack of appropriate peroneus fatigue in this study. Key Words: Ankle stiffness, functional ankle instability, peroneus longus fatigue.

description: The Large Electron Positron Collider (LEP) established the Standard Model (SM) of particle physics with unprecedented precision, including all its radiative corrections. These led to predictions for the masses of the top quark and Higgs boson, which were beautifully confirmed later on. After these precision measurements the Nobel Prize in Physics was awarded in 1999 jointly to 't Hooft and Veltman "for elucidating the quantum structure of electroweak interactions in physics". Another hallmark of the LEP results were the precise measurements of the gauge coupling constants, which excluded unification of the forces within the SM, but allowed unification within the supersymmetric extension of the SM. This increased the interest in Supersymmetry (SUSY) and Grand Unified Theories, especially since the SM has no candidate for the elusive dark matter, while Supersymmetry provides an excellent candidate for dark matter. In addition, Supersymmetry removes the quadratic divergencies of the SM and {\it predicts} the Higgs mechanism from radiative electroweak symmetry breaking with a SM-like Higgs boson having a mass below 130 GeV in agreement with the Higgs boson discovery at the LHC. However, the predicted SUSY particles have not been found either because they are too heavy for the present LHC energy and luminosity or Nature has found alternative ways to circumvent the shortcomings of the SM.

description: The larvae of black soldier fly (BSFL) can convert organic waste into insect proteins. Their bioconversion performance is considerably reduced under hot and cold conditions. To address this problem, we performed selective breeding of BSFL at 16 °C (T16) and 40 °C (T40), and evaluated differentially expressed genes and proteins in the heat- and cold-tolerant breed. Both T16 and T40 breeds exhibited higher body weight, survival rate, and substrate reduction efficiency compared to control groups (C16 and C40). Transcriptome analysis showed significant gene expression changes in both T16 and T40 groups at various time points compared to control groups. Specifically, T16 had 84 upregulated and 64 downregulated genes, while T40 had 117 upregulated and 483 downregulated genes. Full-length transcriptome analyses revealed 27,414 new transcripts in the T16 group. Proteomic analysis revealed 57 upregulated and 114 downregulated proteins in T16, and 128 upregulated and 68 downregulated in T40. The upregulated genes, proteins, and novel transcripts in the bred strains mainly participated in Toll and Imd signalling, carbon metabolism, carbohydrate metabolism, fatty acid biosynthesis and metabolism, and amino acid metabolism. These findings provide insights into the molecular mechanisms that help BSFL to adapt to cold and heat stress.

description: In this study, an artificial neural network (ANN) based on particle swarm optimization (PSO) was developed for the time series prediction. The hybrid ANN+PSO algorithm was applied on Mackey--Glass chaotic time series in the short-term $x(t+6)$. The performance prediction was evaluated and compared with another studies available in the literature. Also, we presented properties of the dynamical system via the study of chaotic behaviour obtained from the predicted time series. Next, the hybrid ANN+PSO algorithm was complemented with a Gaussian stochastic procedure (called {\it stochastic} hybrid ANN+PSO) in order to obtain a new estimator of the predictions, which also allowed us to compute uncertainties of predictions for noisy Mackey--Glass chaotic time series. Thus, we studied the impact of noise for several cases with a white noise level ($σ_{N}$) from 0.01 to 0.1.

description: While a majority of mass loss from the Greenland Ice Shelf is attributed to glacial terminus retreat via calving, the superimposed force factors of the ice-ocean interface create a challenge for physically modeling terminus change. Here we use time series of environmental and glacial data, input as features into a machine learning regression model, to forecast terminus retreat for marine-terminating glaciers in Greenland. We then identify the critical features that most impact a glacier’s likelihood of retreat using SHAP analysis. We further analyze the heterogeneous outcomes for individual glaciers to classify them by their terminus change profile. By better understanding the parameters impacting glacial retreat, we inform physical models to reduce uncertainty in mass change projections.

description: We prove Cheeger inequalities for p-Laplacians on finite and infinite weighted graphs. Unlike in previous works, we do not impose boundedness of the vertex degree, nor do we restrict ourselves to the normalized Laplacian and, more generally, we do not impose any boundedness assumption on the geometry. This is achieved by a novel definition of the measure of the boundary which is using the idea of intrinsic metrics. For the non-normalized case, our bounds on the spectral gap of p-Laplacians are already significantly better for finite graphs and for infinite graphs they yield non-trivial bounds even in the case of unbounded vertex degree. We, furthermore, give upper bounds by the Cheeger constant and by the exponential volume growth of distance balls.
