description: The observations of the surfaces of the mid sized Saturnian satellites made by Cassini Huygens mission have shown a variety of features that allows study of the processes that took place and are taking place on those worlds. Research of the Saturnian satellite surfaces has clear implications for Saturn history and surroundings. In a recent paper, the production of craters on the mid sized Saturnian satellites by Centaur objects was calculated considering the current Solar System. We have compared our results with crater counts from Cassini images and we have noted that the number of observed small craters is less than our calculated number. In this paper we estimate the age of the surface for each observed terrain on each mid sized satellite of Saturn. We have noticed that since there are less observed small craters than calculated (except on Iapetus), this results in younger ages. This could be the result of efficient endogenous or exogenous process(es) for erasing small craters and or crater saturation at those sizes. The size limit from which the observed number of smaller craters is less than the calculated is different for each satellite, possibly indicating processes that are unique to each, but other potential common explanations would be crater saturation and or deposition of E ring particles. These processes are also suggested by the findings that the smaller craters are being preferentially removed, and the erasure process is gradual. On Enceladus, only mid and high latitude plains have remnants of old terrains; the other regions could be young; the regions near the South Polar Terrain could be as young as 50 Myr old. On the contrary for Iapetus, all the surface is old and it notably registers a primordial source of craters. As the crater size is decreased, it would be perceived to approach saturation until D less than 2 km craters, where saturation is complete.

description: Analysis of a large set of phase-resolved $K$-band spectra of the cataclysmic variable WZ Sge shows that the secondary star of this system appears to be an L-dwarf. Previous $K$-band spectra of WZ Sge found that the CO overtone bandheads were in emission. We show that absorption from the $^{\rm 12}$CO$_{\rm (2,0)}$ bandhead of the donor star creates a dip in the $^{\rm 12}$CO$_{\rm (2,0)}$ emission feature. Measuring the motion of this feature over the orbital period, we construct a radial velocity curve that gives a velocity amplitude of K$_{\rm abs}$ = 520 $\pm$ 35 km s$^{\rm -1}$, consistent with the previously published values for this parameter.

description: Stars in open clusters are powerful probes of the intervening Galactic magnetic field, via background starlight polarimetry, because they provide constraints on the magnetic field distances. We use 2MASS photometric data for a sample of 31 clusters in the outer Galaxy, for which near-IR polarimetric data were obtained, to determine the cluster distances, ages, and reddenings via fitting theoretical isochrones to cluster color-magnitude diagrams. The fitting approach uses an objective chi^2 minimization technique to derive the cluster properties and their uncertainties. We found the ages, distances, and reddenings for 24 of the clusters, and the distances and reddenings for six additional clusters that were either sparse or faint in the near-IR. The derived ranges of log(age), distance, and E(B-V) were 7.25-9.63, ~670-6160 pc, and 0.02-1.46 mag, respectively. The distance uncertainties ranged from ~8 to 20%. The derived parameters were compared to previous studies, and most cluster parameters agree within our uncertainties. To test the accuracy of the fitting technique, synthetic clusters with 50, 100, or 200 cluster members and a wide range of ages were fit. These tests recovered the input parameters within their uncertainties for more than 90% of the individual synthetic cluster parameters. These results indicate that the fitting technique likely provides reliable estimates of cluster properties. The distances derived will be used in an upcoming study of the Galactic magnetic field in the outer Galaxy.

Fred Wilson's Mixed Metaphors: The Politics of Museums in the Late Twentieth Century
Creators: name: Ambroso, Aaron
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Against the background of tensions animating museum discourse of the 1980s, Mixed Metaphors challenged both art and artifact methods of display and discourses of authenticity. Instead of lamenting changes in indigenous societies, or rearticulating narratives of the redemption and preservation of indigenous culture from immanent destruction or contamination, Mixed Metaphors pushed SAM to further articulate its values of global, cross-cultural, and future oriented indigenous presents. Mixed Metaphors formed a continuation of the practices and approaches already in use at the museum, challenging characterizations of artist versus museum binaries. Through his intervention, Wilson opened the galleries up to meanings outside of the art and artifact paradigms of classification, interpretation, and display. Ultimately, the installations participated in questioning some of the organizing principles of the museum’s role as collectors and preservers of art and culture.

Year: 2012

description: The European Union has declared 2012 as the European Year for Active Ageing and Solidarity between Generations with the goal of raising awareness about the growing ageing population and to promote a more active lifestyle for older generations. This European Year highlights a different aspect of the demographic change going on in Europe, when usually most attention is placed on the declining fertility rate. But why is the EU addressing this issue now? Has the ageing population always been a concern? This paper will work towards answering those questions and will provide a historical overview of how this issue has emerged on the EU agenda by using a five-step policy process.

description: In the framework of the present phase -- IPOPv2 -- of the international Opacity Project (OP), a new web service has been implemented based on the latest release of the OP opacities. The user may construct online opacity tables to be conveniently included in stellar evolution codes in the format most commonly adopted by stellar physicists, namely the OPAL format. This facility encourages the use and comparison of both the OPAL and OP data sets in applications. The present service allows for the calculation of multi-element mixtures containing the 17 species (H, He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Cr, Mn, Fe and Ni) considered by the OP, and underpins the latest release of OP opacities. This new service provides tables of Rosseland mean opacites using OP atomic data. We provide an alternative to the OPAL opacity services allowing direct comparison as well as study of the effect of uncertainties in stellar modeling due to mean opacities.

description: We present a Python extension to the massively parallel HPC simulation toolkit waLBerla. waLBerla is a framework for stencil based algorithms operating on block-structured grids, with the main application field being fluid simulations in complex geometries using the lattice Boltzmann method. Careful performance engineering results in excellent node performance and good scalability to over 400,000 cores. To increase the usability and flexibility of the framework, a Python interface was developed. Python extensions are used at all stages of the simulation pipeline: They simplify and automate scenario setup, evaluation, and plotting. We show how our Python interface outperforms the existing text-file-based configuration mechanism, providing features like automatic nondimensionalization of physical quantities and handling of complex parameter dependencies. Furthermore, Python is used to process and evaluate results while the simulation is running, leading to smaller output files and the possibility to adjust parameters dependent on the current simulation state. C++ data structures are exported such that a seamless interfacing to other numerical Python libraries is possible. The expressive power of Python and the performance of C++ make development of efficient code with low time effort possible.
The Characterization of Normal Weight Obesity in College Students
Creators: name: Anderson, Kara
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The present study sought to characterize normal weight obesity (NWO) in a sample of undergraduate college students (n=94) with measures of body composition, cardiometabolic markers, and lifestyle questionnaires. Individuals were identified as NWO based on total body fat percentage (BF%) cutoffs of: NHANES 25th BF% percentile, NHANES 50th BF% percentile, and values established by Heo et al. Results were compared between NWO and normal weight lean (NWL) groups of the total sample, along with sex specific cohorts. Results indicated that the NWO occurrence ranged from 8-30%, with a higher occurrence in males. NWO individuals had higher fat mass, trunk fat, visceral fat, and larger waist to hip ratio than NWL. NWO also engaged in less vigorous physical activity and had fewer problems related to alcohol. It is apparent that NWO exists in a college population; more research is needed to fully understand the immediate and long-term implications of this prevalence.

R-Matrix incorporating Time (RMT) method for H2+ in short and intense laser fields

Publisher: name: arXiv
Year: 2015

subject: FOS: Physical sciences

description: In this work we develop an approach for a molecular hydrogen ion (H2+) in the Born-Oppenheimer approximation while exposed to intense short-pulse radiation. Our starting point is the R-Matrix incorporating Time (RMT) formulation for atomic hydrogen [L. A. A. Nikolopoulos et al, Phys. Rev. A 78, 063420 (2008)] which has proven to be successful at treating multi-electron atomic systems efficiently and to high accuracy [L. R. Moore et al J. Mod. Opt. 58,1132, (2011)]. The present study on H2+ has been performed with a similar objective of developing an ab initio method for solving the Time-dependent Schrödinger Equation (TDSE) for multi-electron diatomic molecules exposed to an external time-dependent potential field. The theoretical formulation is developed in detail for the molecular hydrogen ion where all the multi-electron and inter-nuclei complications are absent. As in the atomic case, the configuration space of the electron's coordinates are separated artificially over two regions; the inner (I) and outer (II) regions. In the region I the time-dependent wavefunction is expanded on the eigenstate basis corresponding to the molecule's Hamiltonian augmented by Bloch operators, while in region II a grid representation is used. We demonstrate the independence of our results on the introduced artificial boundary-surface by calculating observables that are directly accessed experimentally and also by showing gauge-dependent quantities are also invariant with the region I box size. We also compare with other theoretical works and emphasize cases where basis-set approaches are currently very computationally expensive or intractable in terms of computational resources.
Nonlocal spin torques in Rashba quantum wires with steep magnetic textures

description: We provide a general procedure to calculate the current-induced spin-transfer torque which acts on a general steep magnetic texture due to the exchange interaction with an applied spin-polarized current. As an example, we consider a one-dimensional ferromagnetic quantum wire and also include a Rashba spin-orbit interaction. The spin-transfer torque becomes generally spatially non-local. Likewise, the Rashba spin-orbit interaction induces a spatially nonlocal field-like nonequilibrium spin-transfer torque. We also find a spatially varying nonadiabaticity parameter and markedly different domain wall dynamics for very steep textures as compared to wide domain walls.

We compare spiral inflation and Dante's inferno-type models, which differ only in their field-space metric. We justify a single-field effective description in these models and relate the single-field description to a mass-matrix formalism. We note the effects of the nontrivial field-space metric on inflationary observables, and consequently on the viability of these models. We also note a duality between spiral inflation and Dante's inferno models with different potentials.

description: We evaluate the coupling of a Bose-Einstein condensate of ultracold, paramagnetic atoms to the magnetic field of the current in a mechanically vibrating carbon nanotube within the frame of a full quantum theory. We find that the interaction is strong enough to sense quantum features of the nanowire current noise spectrum by means of hyperfine-state-selective atom counting. Such a non-destructive measurement of the electric current via its magnetic field corresponds to the classical galvanometer scheme, extended to the quantum regime of charge transport. The calculated high sensitivity of the interaction in the nanowire-BEC hybrid systems opens up the possibility of quantum control, which may be further extended to include other relevant degrees of freedom.

description: The dynamical mean field theory (DMFT) has become a standard technique for the study of strongly correlated models and materials overcoming some of the limitations of density functional approaches based on local approximations. An important step in this method involves the calculation of response functions of a multiorbital impurity problem which is related to the original model. Recently there has been considerable progress in the development of techniques based on the density matrix renormalization group (DMRG) and related matrix product states (MPS) implying a substantial improvement to previous methods. In this article we review some of the standard algorithms and compare them to the newly developed techniques, showing examples for the particular case of the half-filled two-band Hubbard model.

description: We examine the interplay of interaction and disorder for a Heisenberg spin ladder system with random fields. We identify many-body localized states based on the entanglement entropy scaling, where delocalized and localized states have volume and area laws, respectively. We first establish the quantum phase transition at a critical random field strength $h_c \sim 8.5\pm 0.5$, where all energy eigenstates are localized beyond that value. Interestingly, the entanglement entropy and fluctuation of the bipartite magnetization show distinct probability distributions which characterize different quantum phases. Furthermore, we show that for weaker $h$, energy eigenstates with higher energy density are delocalized while states at lower energy density are localized. This defines a mobility edge and a mobility gap separating these two phases. By following the evolution of low energy eigenstates, we observe that the mobility gap grows with increasing the random field strength, which drives the system to the phase of the full many-body localization with increasing disorder strength.

Spectroscopic survey of emission-line stars. I. B[e] stars

description: Emission-line stars are typically surrounded by dense circumstellar material, often in form of rings or disc-like structures. Line emission from forbidden transitions trace a diversity of density and temperature regimes. Of particular interest are the forbidden lines of [O I] λλ6300, 6364 and [Ca II] λλ7291, 7324. They arise in complementary, high-density environments, such as the inner-disc regions around B[e] supergiants. To study physical conditions traced by these lines and to investigate how common they are, we initiated a survey of emission-line stars. Here, we focus on a sample of nine B[e] stars in different evolutionary phases. Emission of the [O I] lines is one of the characteristics of B[e] stars. We find that four of the objects display [Ca II] line emission: for the B[e] supergiants V1478 Cyg and 3 Pup the kinematics obtained from the [O I] and [Ca II] line profiles agrees with a Keplerian rotating disc scenario; the forbidden lines of the compact planetary nebula OY Gem display no kinematical broadening beyond spectral resolution; the LBV candidate V1429 Aql shows no [O I] lines, but the profile of its [Ca II] lines suggests that the emission originates in its hot, ionized circumbinary disc. As none of the B[e] stars of lower mass displays [Ca II] line emission, we conclude that these lines are more likely observable in massive stars with dense discs, supporting and strengthening the suggestion that their appearance requires high-density environments.

Creating and Maintaining an Organizational Culture of Value: A Study of NCAA Division III Volleyball Coaches and Student-Athletes
Creators: name: Kirby, Samantha
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: In 2006, Myles Brand noted that many Division III schools see almost 30% of their student population participating in intercollegiate athletics. With such a large portion of Division III students taking part in intercollegiate athletics, it is vital to analyze those who work with the student-athletes on a day-to-day basis. This study uses transformational leadership and the leader-value continuum to examine whether or not coaches mold their team around an organizational culture that can foster the development of values within their student-athletes. It specially addresses the priority of values among coaches and student-athletes in five core areas; academics, athletics, campus/community involvement, conduct, and student-athlete development. The study uses an electronically distributed survey to all Division III Head Volleyball Coaches and Student-athletes. The results were analyzed using descriptive statistics and T-Tests.

EXPERIENCING ADDICTION AND DEPENDENCY  AMONG YOUTH IN JAMMU, INDIA
Creators: name: Gupta, Sugandh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: In this thesis, I advocate for an ethnographic study of addiction experiences based on 8 weeks of preliminary fieldwork during the summer of 2017 among youth residing in Jammu City, Jammu and Kashmir, India. I expand the scholarship on the anthropology of addiction to South Asia by demonstrating how addiction experience is constituted in the everyday: through kinship relations, regional and national histories, and medical and juridical regimes of state-sponsored institutions. I do so by exploring the cultural and moral practice of ‘dependency’ as a productive lens onto addiction experience, and which has long-served as an important idiom to theorize classic understandings of ‘Indian personhood’ and the ‘Indian Self’ in the South Asia literature. By locating addiction in the intimate relations of reliance and care that unfold between people, substances and institutions, my effort is to rethink ‘dependency’ at the conjuncture of regional and national histories in Jammu, India.

description: We present a high-sensitivity measurement technique for mechanical nanoresonators. Due to intrinsic nonlinear effects, different flexural modes of a nanobeam can be coupled while driving each of them on resonance. This mode-coupling scheme is dispersive and one mode resonance shifts with respect to the motional amplitude of the other. The same idea can be implemented on a {\it single} mode, exciting it with two slightly detuned signals. This two-tone scheme is used here to measure the resonance lineshape of one mode through a frequency shift in the response of the device. The method acts as an amplitude-to-frequency transduction which ultimately suffers only from phase noise of the local oscillator used and of the nanomechanical device itself. We also present a theory which reproduces the data without free parameters.

A phase-field model of relaxor ferroelectrics based on random field theory

Publisher: name: arXiv
Year: 2015
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: A mechanically coupled phase-field model is proposed for the first time to simulate the peculiar behavior of relaxor ferroelectrics. Based on the random field theory for relaxors, local random fields are introduced to characterize the effect of chemical disorder. This generic model is developed from a thermodynamic framework and the microforce theory and is implemented by a nonlinear finite element method. Simulation results show that the model can reproduce relaxor features, such as domain miniaturization, small remnant polarization and large piezoelectric response. In particular, the influence of random field strength on these features are revealed. Simulation results on domain structure and hysteresis behavior are discussed and compared with related experimental results.

Asian Americans--Study and teaching

description: This thesis explores, through the world of one family, how Lao-Americans have crafted their home in a small southern community. By chronicling their experiences in Morganton, North Carolina, I tell a larger story about emergent global landscapes across the South. The extended Phapphayboun family is an anchor for the Lao-American community in Morganton. With three generations now united, the family asserts their Lao heritage every day. This project explores three realms essential to the Phapphayboun's identity: their home and holiday traditions; the family restaurant; and the local temple they helped establish. Across each of this family's worlds, traditional foodways knit together the threads of their identity for personal and public display. Food gives the Phapphayboun family a strong foundation. It is the taste of Laos, played out in papaya salad and chilies, which enables the Phapphaybouns to exercise their heritage among one another, the local Lao community, and other Morgantonians
Atomic Quadrupole Moment Measurement Using Dynamic Decoupling

description: We present a method that uses dynamic decoupling of a multi-level quantum probe to distinguish small frequency shifts that depend on $m^2_{j}$, where $m^2_{j}$ is the angular momentum of level $\left|j\right\rangle$ along the quantization axis, from large noisy shifts that are linear in $m_{j}$, such as those due to magnetic field noise. Using this method we measured the electric quadrupole moment of the $4D_{\frac{5}{2}}$ level in $^{88}Sr^{+}$ to be $2.973^{+0.026}_{-0.033}\, ea_{0}^{2}$. Our measurement improves the uncertainty of this value by an order of magnitude and thus helps mitigate an important systematic uncertainty in $^{88}Sr^{+}$ based optical atomic clocks and verifies complicated many-body quantum calculations.
