description: We investigate the effect of mechanical strain on the dynamics of thin $\mathrm{MoS_2}$ nanodrum resonators. Using a piezoelectric crystal, compressive and tensile biaxial strain is induced in initially flat and buckled devices. In the flat device, we observe a remarkable strain-dependence of the resonance line width, while the change in the resonance frequency is relatively small. In the buckled device, the strain-dependence of the damping is less pronounced, and a clear hysteresis is observed. The experiment suggests that geometric imperfections, such as microscopic wrinkles, could play a role in the strong dissipation observed in nanoresonators fabricated from 2-D materials.

description: Proximal dental caries remains a prevalent disease with only modest detection rates by current diagnostic systems. X-ray radiography represents the most common and successful means of diagnosing early dental caries lesions, however; many new systems are available without controlled validation of diagnostic efficacy. This study evaluated the caries detection of three new dental radiographic imaging technologies: an intraoral digital detector employing an advanced sharpening filter, an extraoral "panoramic bitewing" imaging unit, and a cone beam-CT system with advanced artifact reduction. An ex vivo study design using extracted human teeth, expert observer ratings, and micro-CT ground truth analysis was employed. All modalities performed similarly in overall diagnostic accuracy yet differences were noted in selected system sensitivities and specificities. The CBCT system demonstrated the best assessment of lesion depth and lesion cavitation. Incorporating hydroxyapatite calibration phantoms allowed assessment of imaging consistency, linearity, and contrast resolution.

The effects of hip musculature on knee valgus during a squat task with and without a 2-inch heel block
Creators: name: Vesci, Brian J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Objective: To compare hip ROM, strength, muscle activity, and ankle dorsiflexion ROM between groups that demonstrate knee valgus during a squat task and those that do not (control). Also, determine if muscle activity changes after knee valgus is corrected by a twoinch heel block. Design: A single-session experimental research design was used to compare the control group and the valgus group. Participants: Seventeen (10 Females, 7 Males) control subjects (age[yr] = 23.82 ± 5.76, height[cm] = 166.12 ± 31.13, weight[kg] = 69.59 ± 15.37) and fourteen (12 Female, 2 Male) valgus subjects (age[yr] = 22.36 ± 3.08, height[cm] = 167.21 ± 9.3, weight[kg] = 65.93 ± 9.9) without lower extremity injury. Dependent Variables: Supine hip abduction and external rotation ROM. Ankle dorsiflexion ROM (straight and bent knee). Hip internal rotation, external rotation, extension, and abduction eccentric and concentric peak torque and time to peak torque. EMG mean amplitude of the gluteus maximus, gluteus medius and adductor complex during a squat with and without a two inch heel block. Data Analysis: Mixed model analysis of variance tested for difference both between and within groups. Results: A significant group by phase interaction effect (p = 0.02) existed for mean adductor amplitude between the valgus and the control group. A significant difference (p < .001) in straight knee ankle dorsiflexion ROM existed between the control and the valgus group. A significant difference (p = 0.034) existed between the internal rotation concentric time to peak torque between the two groups. Conclusion: The adductor complex plays a significant role in hip extension. Increased activity of the adductor during extension could pull the knees into valgus. Gastrocnemius tightness might contribute to knee valgus during a squat. There appears to be three distinct populations when considering this knee valgus squatting position. 1. Normal individuals who do not have valgus. 2. Ankle dysfunction individuals who’s valgus position corrects with a heel block. 3. Hip dysfunction individuals who’s valgus position does not correct with a heel block.

description: RISTRETTO is a visible high-resolution spectrograph fed by an extreme adaptive optics (AO) system, to be proposed as a visitor instrument on ESO VLT. The main science goal of RISTRETTO is to pioneer the detection and atmospheric characterisation of exoplanets in reflected light, in particular the temperate rocky planet Proxima b. RISTRETTO will be able to measure albedos and detect atmospheric features in a number of exoplanets orbiting nearby stars for the first time. It will do so by combining a high-contrast AO system working at the diffraction limit of the telescope to a high-resolution spectrograph, via a 7-spaxel integral-field unit (IFU) feeding single-mode fibers. Further science cases for RISTRETTO include the study of accreting protoplanets such as PDS70b/c through spectrally-resolved H-alpha emission, and spatially-resolved studies of Solar System objects such as icy moons and the ice giants Uranus and Neptune. The project is in the manufacturing phase for the spectrograph sub-system, and the preliminary design phase for the AO front-end. Specific developments for RISTRETTO include a novel coronagraphic IFU combining a phase-induced amplitude apodizer (PIAA) to a 3D-printed microlens array feeding a bundle of single-mode fibers. It also features an XAO system with a dual wavefront sensor aiming at high robustness and sensitivity, including to pupil fragmentation. RISTRETTO is a pathfinder instrument in view of similar developments at the ELT, in particular the SCAO-IFU mode of ELT-ANDES and the future ELT-PCS instrument.

description: Inspired by large applications of topological defects in describing different phenomena in physics, and considering the importance of three dimensional solutions in AdS/CFT correspondence, in this paper we obtain magnetic anti-de Sitter solutions of nonlinear electromagnetic fields. We take into account three classes of nonlinear electrodynamic models; first two classes are the well-known BornInfeld like models including logarithmic and exponential forms and third class is known as the power Maxwell invariant nonlinear electrodynamics. We investigate the effects of these nonlinear sources on three dimensional magnetic solutions. We show that these asymptotical AdS solutions do not have any curvature singularity and horizon. We also generalize the static metric to the case of rotating solutions and find that the value of the electric charge depends on the rotation parameter. Finally, we consider the quadratic Maxwell invariant as a correction of Maxwell theory and in other words, we investigate the effects of nonlinearity as a correction. We study the behavior of the deficit angle in presence of these theories of nonlinearity and compare them with each other. We also show that some cases with negative deficit angle exists which are representing objects with different geometrical structure. We also show that in case of the static only magnetic field exists whereas by boosting the metric to rotating one, electric field appear too.

La cuestión de honor en las dos versiones de El alcalde de Zalamea
Creators: name: Trexler, Elizabeth I.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The following article explores how the Golden Age dramatists, Félix Lope de Vega Carpio and Pedro Calderón de la Barca defined the term honor in their versions of El alcalde de Zalamea and how that definition differentiates from the medieval concept of the term. Both authors arrive at a new definition of honor through the comedies' protagonist Pedro Crespo and according to both authors, honor is no longer a quality that only the nobility can possess. The article concludes that it is through Pedro Crespo's judicial duties as mayor that Lope derives his new definition, while it is through the evolution of Pedro Crespo's character and the contrasts that Calderón establishes between Pedro Crespo and don Álvaro that Calderón arrives at his new definition of honor.
Cohomological framework for contextual quantum computations

description: We describe a cohomological framework for measurement based quantum computation, in which symmetry plays a central role. Therein, the essential information about the computational output is contained in topological invariants, namely elements of two cohomology groups. One of those invariants applies to the deterministic case, and the other to the general probabilistic case. The same invariants also witness quantumness in the form of contextuality. In result, they give rise to fundamental algebraic structures underlying quantum computation.

ASSOCIATIONS BETWEEN PATELLAR TENDON STRUCTURE, MOVEMENT QUALITY, AND TRAINING CHARACTERISITICS IN MALE COLLEGIATE ATHLETES
Creators: name: Rankin, Kelsey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Purpose: Ultrasound tissue characterization (UTC) is an imaging tool used to quantify tendon structural integrity. UTC has quantified patellar tendon response to load in athletes; however, PT structure between two conversely loaded high volume sports has yet to be compared.
      Methods: The JV Men's Basketball team (n=13) and Varsity Men's Swim team (n=13) at the University of North Carolina at Chapel Hill were imaged using the UTC device with a 10-MHz linear-array transducer mounted in a tracking device. The device captures images at 0.2mm intervals along the AT. UTC algorithms quantified the stability of pixel brightness over every 17 contiguous transverse images  into 4 echo-types (I-IV).  Participants completed a jump-landing task using the Electromagnetic Motion Capture System. The dominant limb of each participant was analyzed for patellar tendon structure and landing biomechanics. All participants completed a self-report training load questionnaire, including the validated PT assessment the VISA-P. Independent Samples T-tests, correlations and multiple linear regression model were used to assess association and correlation between tendon structure and measures of training intensity.
      Results: 26 subjects completes this study. There was significant difference in tendon structure between basketball and swim athletes (p = 0.04) with basketball athletes presenting with significantly less aligned tendon structure. There was moderate association between training intensity and tendon structure. Discussion: Training intensity and training load may negatively influence patellar tendon structural integrity.

description: An investigation on the mechanism of relaxation of axially confined 400 GeV/c protons to planar channeling in a bent crystal was carried out at the extracted line H8 from CERN Super Proton Synchrotron. The experimental results were critically compared to computer simulations, showing a good agreement. We firmly individuated a necessary condition for the exploitation of axial confinement or its relaxation for particle beam manipulation in high-energy accelerators. We demonstrated that with a short bent crystal, aligned with one of its main axis to the beam direction, it is possible to realize either a total beam steerer or a beam splitter with adjustable intensity. In particular, in the latter case, a complete relaxation from axial confinement to planar channeling takes place, resulting in beam splitting into the two strongest skew planar channels.

How the nature of expression constitutes a problem for expressivism
Creators: name: Sias, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Expressivism in ethics is the view that moral language functions to express only the conative mental states of speakers. After distinguishing between two different senses of expression, and three different ways in which the expressivist might account for the expressive function of moral language, I explain that expressivists owe us an account of how it is that speakers express their mental states by making moral claims. Then I go on to develop just such an account, and in the end, the account puts expressivists in an awkward position. For if my account of expression is on point, then either (a) expressivists are committed to saying that competent users of moral language are often confused (perhaps even systematically so) about their own mental states and their own reasons for action, or (b) expressivism is false.

description: Weak Wave Turbulence is a powerful theory to predict statistical observables of diverse relevant physical phenomena, such as ocean waves, magnetohydrodynamics and nonlinear optics. The theory is based upon an asymptotic closure permitted in the limit of small nonlinearity. Here, we explore the possible deviations from this mean-field framework, in terms of anomalous scaling, focusing on the case of elastic plates. We establish the picture of the possible behaviors at varying the extent of nonlinearity, and we show that the mean-field theory is appropriate when all excited scales remain dominated by linear dynamics. The other picture is non-trivial and our results suggest that, when large scales contain much energy, the cascade sustains extreme events at small scales and the system displays intermittency.

description: In this manuscript, we will introduce a recently developed program GPView, which can be used for wave function analysis and visualization. The wave function analysis module can calculate and generate 3D cubes for various types of molecular orbitals and electron density of electronic excited states, such as natural orbitals, natural transition orbitals, natural difference orbitals, hole-particle density, detachment-attachment density and transition density. The visualization module of GPView can display molecular and electronic (iso-surfaces) structures. It is also able to animate single trajectories of molecular dynamics and non-adiabatic excited state molecular dynamics using the data stored in existing files. There are also other utilities to extract and process the output of quantum chemistry calculations. The GPView provides full graphic user interface (GUI), so it very easy to use. It is available from website \href{http://life-tp.com/gpview}{http://life-tp.com/gpview}.

Some properties the spacetime are discussed, such as the electromagnetic fields, the area-temperature product, and the holography according to Kerr/CFT correspondence. As expected, the macroscopic Bekenstein-Hawking entropy for an extremal accelerating Kaluza-Klein black hole can be recovered by using Cardy formula of a two dimensional conformal field theory. An interesting feature is found, namely the area-temperature product is just the the one belongs to the vacuum Einstein seed solution.

description: Slow oscillations (SlO) of magnetoresistance is a convenient tool to measure electronic structure parameters in quasi-two-dimensional metals. We study the possibility to apply this method to multi-band conductors, e.g. to iron-based high-temperature superconducting materials. We show that SlO can be used to measure the interlayer transfer integral in multi-band conductors similar to single-band metals. In addition, the SlO allow to measure and compare the effective masses or the electron scattering rates in various bands.

description: We extract the strong coupling constants of three mesons, each of which is composed of either two charm quarks or one charm quark and one light (i.e., $u$, $d$, or $s$) quark, from the matrix elements for the transitions of two of these mesons induced by appropriate quark currents within the framework of a relativistic dispersion approach to the constituent-quark picture of mesons. Among others, we also analyse the impact of the violation of the SU(3) flavour symmetry by the quark masses. In the case of mesons containing one light quark, we observe, in two respects, discrepancies between our findings and the predictions of QCD sum rules: our strong couplings exceed considerably the ones emerging from QCD sum rules, and, in our approach, the replacement of a light quark by a strange quark entails, in contrast to QCD sum rules, a reduction of the magnitudes of the strong couplings.

description: The origin of the near-infrared (NIR) HI emission lines in young stellar objects are not yet understood. To probe it, we present multi-epoch LBT-LUCIFER spectroscopic observations of the Paδ, Paβ, and Brγ lines observed in the Herbig star VVSer, along with VLTI-AMBER Brγ spectro-interferometric observations at medium resolution. Our spectroscopic observations show line profile variability in all the HI lines. The strongest variability is observed in the redshifted part of the line profiles. The Brγ spectro-interferometric observations indicate that the Brγ line emitting region is smaller than the continuum emitting region. To interpret our results, we employed radiative transfer models with three different flow configurations: magnetospheric accretion, a magneto-centrifugally driven disc wind, and a schematic bipolar outflow. Our models suggest that the HI line emission in VVSer is dominated by the contribution of an extended wind, perhaps a bipolar outflow. Although the exact physical process for producing such outflow is not known, this model is capable of reproducing the averaged single-peaked line profiles of the HI lines. Additionally, the observed visibilities, differential and closure phases are best reproduced when a wind is considered. Nevertheless, the complex line profiles and variability could be explained by changes in the relative contribution of the magnetosphere and/or winds to the line emission. This might indicate that the NIR HI lines are formed in a complex inner disc region where inflow and outflow components might coexist. Furthermore, the contribution of each of these mechanisms to the line appears time variable, suggesting a non-steady accretion/ejection flow.

description: Multi-color photometry of the stellar populations in five fields in the third Galactic quadrant centred on the clusters NGC 2215, NGC 2354, Haffner 22, Ruprecht 11, and ESO489SC01 is interpreted in terms of a warped and flared Galactic disk, without resort to an external entity such as the popular Monoceros or Canis Major overdensities. Except for NGC 2215, the clusters are poorly or unstudied previously. The data generate basic parameters for each cluster, including the distribution of stars along the line of sight. We use star counts and photometric analysis, without recourse to Galactic-model-based predictions or interpretations, and confirms earlier results for NGC 2215 and NGC 2354. ESO489SC01 is not a real cluster, while Haffner~22 is an overlooked cluster aged about 2.5 Gyr. Conclusions for Ruprecht~11 are preliminary, evidence for a cluster being marginal. Fields surrounding the clusters show signatures of young and intermediate-age stellar populations. The young population background to NGC~2354 and Ruprecht~11 lies 8-9 kpc from the Sun and $\sim$1 kpc below the formal Galactic plane, tracing a portion of the Norma-Cygnus arm, challenging Galactic models that adopt a sharp cut-off of the disk 12-14 kpc from the Galactic center. The old population is metal poor with an age of 2-3 Gyr, resembling star clusters like Tombaugh 2 or NGC 2158. It has a large color spread and is difficult to locate precisely. Young and old populations follow a pattern that depends critically on the vertical location of the thin and/or thick disk, and whether or not a particular line of sight intersects one, both, or none.

De Morgan Dual Nominal Quantifiers Modelling Private Names in Non-Commutative Logic

description: This paper explores the proof theory necessary for recommending an expressive but decidable first-order system, named MAV1, featuring a de Morgan dual pair of nominal quantifiers. These nominal quantifiers called `new' and `wen' are distinct from the self-dual Gabbay-Pitts and Miller-Tiu nominal quantifiers. The novelty of these nominal quantifiers is they are polarised in the sense that `new' distributes over positive operators while `wen' distributes over negative operators. This greater control of bookkeeping enables private names to be modelled in processes embedded as formulae in MAV1. The technical challenge is to establish a cut elimination result, from which essential properties including the transitivity of implication follow. Since the system is defined using the calculus of structures, a generalisation of the sequent calculus, novel techniques are employed. The proof relies on an intricately designed multiset-based measure of the size of a proof, which is used to guide a normalisation technique called splitting. The presence of equivariance, which swaps successive quantifiers, induces complex inter-dependencies between nominal quantifiers, additive conjunction and multiplicative operators in the proof of splitting. Every rule is justified by an example demonstrating why the rule is necessary for soundly embedding processes and ensuring that cut elimination holds.

description: In this paper I study between and within country differences in attitudes towards democracy, focusing specifically on Muslim-majority countries and the degree to which college educated and high-income individuals in these countries conform to the expectations of modernization theory in their support for democracy. I find that support for democracy among high-income and college educated individuals is reduced in Muslim-majority countries relative to their peers around the world, but that this finding is due to an environment of political instability as well as levels of national income and democracy.

Research on this topic has been driven by the Černý conjecture, one of the oldest and most famous problems in automata theory, according to which a synchronizing $n$-state automaton has a reset word of length at most $(n-1)^2$. The transitions of an automaton generate a transformation monoid on the set of states, and so an automaton can be regarded as a transformation monoid with a prescribed set of generators. In this setting, an automaton is synchronizing if the transitions generate a constant map. A permutation group $G$ on a set $Ω$ is said to synchronize a map $f$ if the monoid $\langle G,f\rangle$ generated by $G$ and $f$ is synchronizing in the above sense; we say $G$ is synchronizing if it synchronizes every non-permutation. The classes of synchronizing groups and friends form an hierarchy of natural and elegant classes of groups lying strictly between the classes of primitive and $2$-homogeneous groups. These classes have been floating around for some years and it is now time to provide a unified reference on them. The study of all these classes has been prompted by the Černý conjecture, but it is of independent interest since it involves a rich mix of group theory, combinatorics, graph endomorphisms, semigroup theory, finite geometry, and representation theory, and has interesting computational aspects as well. So as to make the paper self-contained, we have provided background material on these topics. Our purpose here is to present results that show the connections between the various areas of mathematics mentioned above, we include a new result on the Černý conjecture, some challenges to finite geometers, some thoughts about infinite analogues, and a long list of open problems.

A Frameless Imaging System: Architectural Design and Simulation

description: This report presents the work on the architectural design and simulation of the IMAGIN sensing system, a novel frameless camera sensor system that can provide a high dynamic range and fine tonal sensitivity, and allow for different update rates from different regions-of-interest. My contribution to the IMAGIN project is threefold. First, starting with a high-level functional concept of the sensor that had been developed by the group, I took it through several design and implementation steps: from functional model to top-level architecture, to pixel-level microarchitecture, to gate-level design of the core sensor array. Second, I validated the behavior and characterized the performance of the sensor via extensive simulation using state-of-the-art tools (Verilog simulation using Xilinx’s Vivado suite). Based on simulation results, I refined and optimized the design by tuning several parameters. Third, I developed equations to compute the dynamic range and tonal sensitivity from design parameters.

description: Modern popular TV series often develop complex storylines spanning several seasons, but are usually watched in quite a discontinuous way. As a result, the viewer generally needs a comprehensive summary of the previous season plot before the new one starts. The generation of such summaries requires first to identify and characterize the dynamics of the series subplots. One way of doing so is to study the underlying social network of interactions between the characters involved in the narrative. The standard tools used in the Social Networks Analysis field to extract such a network rely on an integration of time, either over the whole considered period, or as a sequence of several time-slices. However, they turn out to be inappropriate in the case of TV series, due to the fact the scenes showed onscreen alternatively focus on parallel storylines, and do not necessarily respect a traditional chronology. This makes existing extraction methods inefficient to describe the dynamics of relationships between characters, or to get a relevant instantaneous view of the current social state in the plot. This is especially true for characters shown as interacting with each other at some previous point in the plot but temporarily neglected by the narrative. In this article, we introduce narrative smoothing, a novel, still exploratory, network extraction method. It smooths the relationship dynamics based on the plot properties, aiming at solving some of the limitations present in the standard approaches. In order to assess our method, we apply it to a new corpus of 3 popular TV series, and compare it to both standard approaches. Our results are promising, showing narrative smoothing leads to more relevant observations when it comes to the characterization of the protagonists and their relationships. It could be used as a basis for further modeling the intertwined storylines constituting TV series plots.

Dynamic relaxation oscillations in a nonlinearly driven quartz crystal

description: We demonstrate thermo-mechanical relaxation oscillations in a strongly driven quartz crystal. Dynamic bifurcation leads to two stable oscillation states with a distinct electrical impedance. Slow Joule-heating, which shifts the susceptibility of the crystal, provides a feedback that leads to thermally-induced oscillations, in which the amplitude of the crystal is modulated by a relaxation cycle. The frequency of the relaxation cycle is roughly a million times lower than the resonance frequency of the crystal, and it can be adjusted by the detuning from the critical point for dynamic bifurcation. The experimental observations are reproduced by a simple model that takes into account the slow dynamics of the system.

description: Gamma-ray burst GRB 140430A was detected by the Swift satellite and observed promptly with the imaging polarimeter RINGO3 mounted on the Liverpool Telescope, with observations beginning while the prompt $γ$-ray emission was still ongoing. In this paper, we present densely sampled (10-second temporal resolution) early optical light curves in 3 optical bands and limits to the degree of optical polarization. We compare optical, X-ray and gamma-ray properties and present an analysis of the optical emission during a period of high-energy flaring. The complex optical light curve cannot be explained merely with a combination of forward and reverse shock emission from a standard external shock, implying additional contribution of emission from internal shock dissipation. We estimate an upper limit for time averaged optical polarization during the prompt phase to be as low as P < 12% (1$σ$). This suggests that the optical flares and early afterglow emission in this GRB are not highly polarized. Alternatively, time averaging could mask the presence of otherwise polarized components of distinct origin at different polarization position angles.

description: The Additive Coloring Problem is a variation of the Coloring Problem where labels of $\{1,\ldots,k\}$ are assigned to the vertices of a graph $G$ so that the sum of labels over the neighborhood of each vertex is a proper coloring of $G$. The least value $k$ for which $G$ admits such labeling is called \emph{additive chromatic number} of $G$. This problem was first presented by Czerwiński, Grytczuk and Żelazny who also proposed a conjecture that for every graph $G$, the additive chromatic number never exceeds the classic chromatic number. Up to date, the conjecture has been proved for complete graphs, trees, non-3-colorable planar graphs with girth at least 13 and non-bipartite planar graphs with girth at least 26. In this work, we show that the conjecture holds for split graphs. We also present exact formulas for computing the additive chromatic number for some subfamilies of split graphs (complete split, headless spiders and complete sun), regular bipartite, complete multipartite, fan, windmill, circuit, wheel, cycle sun and wheel sun.
Influence of Dentin Desensitizers on the Microtensile Bond Strengths of Self-Etch and Etch-and-Rinse Adhesives to Dentin

description: This study evaluated several dentin desensitizers' effects on dentin microtensile bond strengths (MTBS) of various self-etch (SE) and etch-and-rinse (ER) adhesives. For ER, dentin from human molars was phosphoric acid-etched, treated with a desensitizer, and coated with the adhesive. For SE, dentin was treated with the same desensitizers, and coated with the adhesive. Composite build-ups were placed and specimens stored in distilled water at 37°C for 24h. Specimens were sectioned into beams and tested either immediately or after 6 months. Data were analyzed using factorial analysis of variance. At 24h, mean MTBS's ranged from 20.0-46.6 MPa for ER and from 22.0-37.0 MPa for SE. At 6 months, mean MTBS's ranged from 22.0-45.4 MPa for ER and from 20.2-33.4 MPa for SE.

description: We show that the two-point function of a quantum field theory with de Sitter momentum space (herein called DSR) can be expressed as the product of a standard delta function and an energy-dependent factor. This is a highly non-trivial technical result in any theory without a preferred frame. Applied to models exhibiting running of the dimensionality of space, this result is essential in proving that vacuum fluctuations are generally scale-invariant at high energies whenever there is running to two dimensions. This is equally true for theories with and without a preferred frame, with differences arising only as we consider higher order correlators. Specifically, the three-point function of DSR has a unique structure of "open triangles", as shown here.
