description: An Android-based smart Television (TV) must reliably run its applications in an embedded program environment under diverse hardware resource conditions. Owing to the diverse hardware components used to build numerous TV models, TV simulators are usually not high enough in fidelity to simulate various TV models, and thus are only regarded as unreliable alternatives when stress testing such applications. Therefore, even though stress testing on real TV sets is tedious, it is the de facto approach to ensure the reliability of these applications in the industry. In this paper, we study to what extent stress testing of smart TV applications can be fully automated in the industrial environments. To the best of our knowledge, no previous work has addressed this important question. We summarize the find-ings collected from 10 industrial test engineers to have tested 20 such TV applications in a real production environment. Our study shows that the industry required test automation supports on high-level GUI object controls and status checking, setup of resource conditions and the interplay between the two. With such supports, 87% of the industrial test specifications of one TV model can be fully automated and 71.4% of them were found to be fully reusable to test a subsequent TV model with major up-grades of hardware, operating system and application. It repre-sents a significant improvement with margins of 28% and 38%, respectively, compared to stress testing without such supports.

When do Revolutions lead to Democracy? The Conflict between Democracy and Governance in Georgia and Tunisia
Creators: name: McCrain, Josh
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: The revolutions that began in Tunisia in late 2010 spread across the region and toppled many seemingly durable authoritarian regimes in the Arab world. These revolutions in the name of democracy drew many comparisons to the popular color revolutions of the early 2000s that ousted leaders of post-communist regimes in Georgia, Ukraine and Kyrgyzstan. Through the benefit of time, observers have noted that the democratic quality of these Eurasian regimes is lacking, and many now exhibit the same characteristics of the regime they deposed through revolution - a worrying sign for democrats in the Arab world. This thesis compares the cases of Georgia and Tunisia by focusing on the conflict between the progressions of democracy versus governance in democratizing, post-revolutionary regimes. In post-revolutionary regimes, either democracy or governance will prevail at the cost of the other, lending key insights into the future democratic development of the case in question.

description: An evaporating droplet is a dynamic system in which flow is spontaneously generated to minimize the surface energy, dragging particles to the borders and ultimately resulting in the so-called "coffee-stain effect". The situation becomes more complex at the droplet's surface, where surface tension gradients of different nature can compete with each other yielding different scenarios. With careful experiments and with the aid of 3D particle tracking techniques, we are able to show that different types of surfactants turn the droplet's surface either rigid or elastic, which alters the evaporating fluid flow, either enhancing the classical coffee-stain effect or leading to a total flow inversion. Our measurements lead to unprecedented and detailed measurements of the surface tension difference along an evaporating droplet's surface with good temporal and spatial resolution.

Impact of Free Chlorine on the Fate of Biochemically Active Compounds in Drinking Water
Creators: name: Kaplan, Jacqueline Pearl
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: As a result of the rapid development of the pharmaceutical and agricultural industries, the biochemically active compounds they produce to treat human ailments, maintain livestock health, and improve crop output are finding their way into the aquatic environment. Surface waters supplying drinking water treatment plants may be particularly vulnerable if the chemicals persist through upstream wastewater treatment or appear in run-off from land application. During drinking water treatment physicochemical processes may remove some of these chemicals or transform them into products with unknown structures and biological activity. In order to better understand the impacts of biochemically active compounds on water supply and their fate during drinking water treatment source, settled, and finished waters from plants in North Carolina were analyzed using liquid chromatography tandem mass spectrometry. Both atrazine and the insecticide DEET were found to consistently survive conventional treatment. Additionally, bench-scale chlorination experiments designed to simulate disinfection were conducted to determine the extent of chlorine incorporation into the parent chemical thereby hiding products from detection which may still have biochemical activity.

description: The purpose of this qualitative study was to explore the experiences of young adults transitioning from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) from the perspectives of patients. Using convenience sampling, six participants were recruited for individual semi-structured interviews. Using conventional content analysis, I identified five categories reflective of the participants' experiences: 1. 'Expectations', 2. 'Transition is a Gradual Process and not an Abrupt Change', 3. 'Factors Influencing Transition', 4. Living the Transition' and 5. 'Improving the Transition'. These categories included subcategories, when appropriate, to highlight variation within the main experiences. The findings provide insight into the experiences of young adults who are - or have lived - the transition from CAMHS to AMHS from their perspectives. The participants' stories are useful to understand the physical and emotional challenges associated with shifting to adult care, and their recommendations can help to inform healthy transitions in this context.

description: Innovative ways to improve and apply hygiene and infection prevention/control knowledge into the daily work routine of hospital staff are not only recommended but also extremely desired. Nudges may play an important role here. However, due to the novelty of the nudge theory, we propose an extension of the concept called "nudging in sensu lato" to include valuable information from work that does not use the nudge theory, yet employ interventions based on mechanisms applied in nudging interventions. This Scoping Review aims to provide an overview of different nudging and nudging in sensu lato interventions that are implemented in hospitals to promote hygiene and infection prevention/control.

description: Spicules are small hairy like structures seen at the solar limb mainly at chromospheric and transition region lines. They generally live for 3-10 minutes. We observe these spicules in a south polar region of the Sun with a coordinated observations using the Interface Region Imaging Spectrograph (IRIS) and the Atmospheric Imaging Assembly (AIA) instruments on board the Solar Dynamics Observatory. Propagating disturbances (PDs) are observed everywhere in the polar off-limb regions of the Sun at coronal heights. From this simultaneous observations we show that the spicules and the PDs may be originated by a common process. From space-time maps we find that the start of the trajectory of PDs is almost co-temporal with the time of the rise of the spicular envelope as seen by IRIS slit-jaw images at 2796 °A and 1400 A° . During the return of spicular material, brightenings are seen in AIA 171 °A and 193 °A images. The quasi-periodic nature of the spicular activity as revealed by the IRIS spectral image sequences and its relation to coronal PDs as recorded by the coronal AIA channels suggest that they have a common origin. We propose that reconnection like processes generate the spicules and waves simultaneously. The waves escape while the cool spicular material falls back

description: Alzheimer's disease (AD) is an incurable disease characterized by a slow, progressive decline in cognitive functions as well as the presence of amyloid-beta (Aβ) plaques and neurofibrillary tangles. Interestingly, two thirds of AD patients are women who have a faster disease progression. Despite this clinical profile, sex differences in AD pathophysiology are largely ignored at the basic and clinical levels. Current therapies provide only mild to moderate improvement in patient symptoms. There is, therefore, an urgent need to expand our understanding of the underlying pathophysiology of AD, and to obtain alternative hypotheses and therapeutics. A recent and promising development involves the sigma-1 receptor (Sig1R), a protein regulated by steroid hormones, which has been implicated in AD. Most interestingly, Sig1R agonists have been shown to ameliorate cognitive deficits in an AD mouse model. Here, we investigated the role of Sig1Rs in an Aβ25-35-infusion mouse model of AD, using behavioural paradigms. Previous studies employing this model have demonstrated Aβ-induced impairments in learning and memory in young male rodents, while no work has been done on females. We examined cognitive function following Aβ25-35 infusion in wild-type and knock-out Sig1R adult male and female mice using the Morris water maze, spontaneous alternation in the Y-maze, and forced alternation in the Y-maze tasks. Overall, the data unexpectedly shows that genotype, Aβ25-35-treatment, and sex had no effect on cognitive functions. These results suggest that additional efforts are required to obtain a working Aβ25-35-infusion model in our Sig1R mice and behavioural tasks. Future experiments will hopefully shed some light on the link between Sig1Rs and AD, which could lead to the development of therapeutics and disease prevention.

Peer Racial Discrimination, Temperament and Academics among Black Adolescents
Creators: name: Volpe, Vanessa Victoria
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: The present study examined the role of peer perceptions of racial discrimination on academic self-concept. The sample (N=277) was drawn from a larger study (Seaton, 2013) of 314 African American adolescents aged 13 to 18. Effortful control was examined as a moderator in this relation. Results suggest that perceptions of peer racial discrimination do not significantly impact adolescents' academic self-concept. Effortful control was not a significant moderator in the relation between perceptions of peer racial discrimination and academic self-concept. However, a direct effect was observed such that effortful control significantly predicted academic self-concept. Results suggest the importance of individual differences in the development of effortful control capacities for African American adolescents' academic success.
In2O3 doped with hydrogen: electronic structure and optical properties from the pseudopotential Self-Interaction Corrected Density Functional Theory and the Random Phase Approximation

description: We discuss the applicability of the pseudopotential-like self-interaction correction (pSIC) to the study of defect energetics and electronic structure of In2O3. Our results predict that substitutional (at oxygen sites) and interstitial (at antibonding positions) hydrogen, as well as oxygen vacancies with charges +1 and +2, are stable configurations of defects in cubic In2O3; the former form shallow levels (only as substitutional defects), whereas the latter form deep levels. The band structure calculated with the pSIC shows an excellent agreement with experimental data. In particular, the gap for defect-free In2O3 is 2.85 eV, which compares fairly with the experimental range 2.3-2.9 eV. The pSIC results also point to a change from indirect to direct gaps depending on doping. In relation to the optical properties, obtained within the random phase approximation, it is shown that they are mostly affected by the presence of oxygen vacancies.

description: In the analysis of frozen hydrated biomolecules by single-particle cryo-electron microscopy, template-based particle picking by a target function called fast local correlation (FLC) allows a large number of particle images to be automatically picked from micrographs. A second, independent target function based on maximum likelihood (ML) can be used to align the images and verify the presence of signal in the picked particles. Although the paradigm of this dual-target-function (DTF) evaluation of single-particle selection has been practiced in recent years, it remains unclear how the performance of this DTF approach is affected by the signal-to-noise ratio of the images and by the choice of references for FLC and ML. Here we examine this problem through a systematic study of simulated data, followed by experimental substantiation. We quantitatively pinpoint the critical signal-to-noise ratio (SNR), at which the DTF approach starts losing its ability to select and verify particles from cryo-EM micrographs. A Gaussian model is shown to be as effective in picking particles as a single projection view of the imaged molecule in the tested cases. For both simulated micrographs and real cryo-EM data of the 173-kDa glucose isomerase complex, we found that the use of a Gaussian model to initialize the target functions suppressed the detrimental effect of reference bias in template-based particle selection. Given a sufficient signal-to-noise ratio in the images and the appropriate choice of references, the DTF approach can expedite the automated assembly of single-particle data sets.

description: Trust is the foundation to a thriving learning community. The intent of this research was to investigate teachers’ perspectives on relational trust among the different members of their learning communities including teachers, students, colleagues and the community. The research design of the study was a mixed methods, paper-based survey. It was created to retrieve quantitative and qualitative data on the current teachers’ perspectives on relational trust and the strategies teachers are using to build relational trust with the members of their learning community. Relational trust is an important factor in academic achievement in learning communities and the data presented shows that the current perspective of teachers in School District #70 is that relational trust exists in strong levels between teachers and all members of their learning community.

description: Controlling the internal degrees of freedom is a key challenge for applications of cold and ultracold molecules. Here, we demonstrate rotational-state cooling of trapped methyl fluoride molecules (CH3F) by optically pumping the population of 16 M-sublevels in the rotational states J=3,4,5, and 6 into a single level. By combining rotational-state cooling with motional cooling, we increase the relative number of molecules in the state J=4, K=3, M=4 from a few percent to over 70%, thereby generating a translationally cold (~30mK) and nearly pure state ensemble of about 10^6 molecules. Our scheme is extendable to larger sets of initial states, other final states and a variety of molecule species, thus paving the way for internal-state control of ever larger molecules.

description: We present a method for synthesizing large area epitaxial single-layer MoS$_2$ on the Au(111) surface in ultrahigh vacuum. Using scanning tunneling microscopy and low energy electron diffraction, the evolution of the growth is followed from nanoscale single-layer MoS$_2$ islands to a continuous MoS$_2$ layer. An exceptionally good control over the MoS$_2$ coverage is maintained using an approach based on cycles of Mo evaporation and sulfurization to first nucleate the MoS$_2$ nano-islands and then gradually increase their size. During this growth process the native herringbone reconstruction of Au(111) is lifted as shown by low energy electron diffraction measurements. Within these MoS$_2$ islands, we identify domains rotated by 60$^{\circ}$ that lead to atomically sharp line defects at domain boundaries. As the MoS$_2$ coverage approaches the limit of a complete single-layer, the formation of bilayer MoS$_2$ islands is initiated. Angle-resolved photoemission spectroscopy measurements of both single and bilayer MoS$_2$ samples show a dramatic change in their band structure around the center of the Brillouin zone. Brief exposure to air after removing the MoS$_2$ layer from vacuum is not found to affect its quality.

From cotton mill to co-op: the rise of a local food culture in Carrboro, North Carolina
Creators: name: Brown, Whitney Elizabeth
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: Once a bustling mill town, Carrboro, North Carolina, is today a haven for local food. Adjacent to a major research university and mile after mile of rolling farmland, Carrboro is a place where, over the last thirty years, a group of citizens armed with progressive values has created a thriving market community for locally produced food. Area farmers' markets, cooperative groceries, home and community gardens, urban chickens, and locally-focused restaurants play a vital role in the community as a whole--both to its identity and its social, political, and economic activities. This project illuminates some of the complex ties that developed between urban and rural, liberal and conservative, rich and poor (and middle class), young and old, cynical and idealistic, modern and traditional to facilitate the local food segment of Carrboro's broader economy. It also investigates local definitions of place, group, taste, and tradition.

description: We use the exact solutions for magnetoacoustic waves in a two dimensional isothermal atmosphere with uniform inclined magnetic field to calculate the wave reflection, transmission, and conversion of slow and fast waves incident from above ($z=\infty$). This is relevant to the question of whether waves excited by flares in the solar atmosphere can penetrate the Alfvén/acoustic equipartition layer (which we identify as the canopy) to reach the photosphere with sufficient energy to create sunquakes. It is found that slow waves above the acoustic cutoff frequency efficiently penetrate (transmit) as acoustic (fast) waves if directed at a small attack angle to the magnetic field, with the rest converting to magnetic (slow) waves, in accord with Generalized Ray Theory. This may help explain the compact nature of seismic sources of sunquakes identified using seismic holography. The incident slow waves can also efficiently transmit at low frequency in inclined field due to the reduction in acoustic cutoff frequency (ramp effect). Incident fast (magnetic) "waves" from infinity with specified nonzero horizontal wavenumber are necessarily evanescent, but can carry energy to the equipartition level by tunnelling. It is found that this can then efficiently convert to acoustic (fast) energy that can again reach the photosphere as a travelling wave. Overall, there appear to be ample avenues for substantial compressive wave energy to penetrate the canopy and impact the photosphere.

description: We present a multigrid based eigensolver for computing low-modes of the Hermitian Wilson Dirac operator. For the non-Hermitian case multigrid methods have already replaced conventional Krylov subspace solvers in many lattice QCD computations. Since the $γ_5$-preserving aggregation based interpolation used in our multigrid method is valid for both, the Hermitian and the non-Hermitian case, inversions of very ill-conditioned shifted systems with the Hermitian operator become feasible. This enables the use of multigrid within shift-and-invert type eigensolvers. We show numerical results from our MPI-C implementation of a Rayleigh quotient iteration with multigrid. For state-of-the-art lattice sizes and moderate numbers of desired low-modes we achieve speed-ups of an order of magnitude and more over PARPACK. We show results and develop strategies how to make use of our eigensolver for calculating disconnected contributions to hadronic quantities that are noisy and still computationally challenging. Here, we explore the possible benefits, using our eigensolver for low-mode averaging and related methods with high and low accuracy eigenvectors. We develop a low-mode averaging type method using only a few of the smallest eigenvectors with low accuracy. This allows us to avoid expensive exact eigensolves, still benefitting from reduced statistical errors.

Intercollegiate participation DI vs DIII: effect on occupational life after sports
Creators: name: Isom, Josh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The educational value of intercollegiate athletics has been debated throughout its history, particularly related to “big time” Division I athletics. Research has postulated Division III athletes are provided with a more high quality academic experience. A survey of former athletes from one Division I institution and one Division III institution examined differences in occupational outcomes between the two groups. The results of this study suggest that there is a significant difference in educational satisfaction but not in work engagement, job satisfaction or salary between football and men’s basketball athlete graduates at the Division I and Division III institutions examined. This study will provide new and novel data, as well as offer avenues for further research on the occupational impacts of intercollegiate athletics participation. It will also present both quantitative and qualitative information to help determine if it benefits the prospective student-athlete to participate on the Division I or Division III level.

description: We present a numerical analysis of the particle creation for a quantum field in the presence of time dependent boundary conditions. Having in mind recent experiments involving superconducting circuits, we consider their description in terms of a scalar field in a one dimensional cavity satisfying generalized boundary conditions that involve a time-dependent linear combination of the field and its spatial and time derivatives. We evaluate numerically the Bogoliubov transformation between {\it in} and {\it out}-states and find that the rate of particle production strongly depends on whether the spectrum of the unperturbed cavity is equidistant or not, and also on the amplitude of the temporal oscillations of the boundary conditions. We provide analytic justifications for the different regimes found numerically.

Optical Properties of ITO/ZnO Schottky Diode with Enhanced UV Photoresponse
Creators: name: Lee, Hsin-Yen

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

description: Photoluminescence (PL) spectra of zinc oxide (ZnO) samples with different hydrogen peroxide (H2O2) treatment durations were measured to examine several point defects on the surface of the films. These results suggest successful oxidation through the reaction between oxygen radicals dissociated from H2O2 and the ZnO surface. To further confirm the defect induced gain mechanism, we fabricate highly transparent Schottky diodes, and measure the key diode characteristics. Photocurrents are measured under different wavelengths, and possible explanations of the high optical gain within the ultraviolet (UV) region are provided.

Linking land use, nutrient conditions and phytoplankton abundance and diversity in the non-tidal creeks of the Neuse-Pamlico Estuarine System
Creators: name: Gallo, Thomas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This project was undertaken to determine how coastal land use and land cover affect dissolved nutrient concentration and form, phytoplankton abundance and community composition, and nitrogen buffering capacity in the non-tidal oligo- to meso-haline creeks of the Neuse Pamlico Estuarine System. The research included routine sampling of four estuarine creeks and seasonal in-situ nutrient addition bioassays designed to mimic nutrient loading events observed in the monitoring data. The results show the land use causing the greatest degree of disturbance (agriculture) resulted in the highest in-stream nutrient concentrations, the highest inorganic to organic nitrogen ratios, the lowest phytoplankton diversity, and decreased capacity to buffer the mainstem estuary from episodic nutrient loading. The findings underscore the need for watershed management designed to mitigate increased fresh water and nutrient loading from watershed modification upstream of estuarine creeks.

description: X-ray magnetic circular dichroism spectroscopy using an X-ray free electron laser is demonstrated with spectra over the Fe L$_{3,2}$-edges. This new ultrafast time-resolved capability is then applied to a fluence-dependent study of all-optical magnetic switching dynamics of Fe and Gd magnetic sublattices in a GdFeCo thin film above its magnetization compensation temperature. At the magnetic switching fuence, we corroborate the existence of a transient ferromagnetic-like state. The timescales of the dynamics, however, are longer than previously observed below the magnetization compensation temperature. Above and below the switching fluence range, we observe secondary demagnetization with about 5 ps timescales. This indicates that the spin thermalization takes longer than 5 ps.

description: When gun laws affect firearm-related homicide or firearm-related suicide, how much are those effects offset or compounded by effects on non-firearm-related homicide and non-firearm-related suicide, respectively? We will estimate separate “mortality multipliers” (m) for homicides and suicides, which represent the change in total homicide (suicide) deaths attributable to the policy, divided by the change in firearm-related homicide (suicide) deaths so attributable. This will be obtained from models using state-level annual counts of total firearm homicides and of total non-firearm homicides.
