description: Mining useful clusters from high dimensional data has received significant attention of the computer vision and pattern recognition community in the recent years. Linear and non-linear dimensionality reduction has played an important role to overcome the curse of dimensionality. However, often such methods are accompanied with three different problems: high computational complexity (usually associated with the nuclear norm minimization), non-convexity (for matrix factorization methods) and susceptibility to gross corruptions in the data. In this paper we propose a principal component analysis (PCA) based solution that overcomes these three issues and approximates a low-rank recovery method for high dimensional datasets. We target the low-rank recovery by enforcing two types of graph smoothness assumptions, one on the data samples and the other on the features by designing a convex optimization problem. The resulting algorithm is fast, efficient and scalable for huge datasets with O(nlog(n)) computational complexity in the number of data samples. It is also robust to gross corruptions in the dataset as well as to the model parameters. Clustering experiments on 7 benchmark datasets with different types of corruptions and background separation experiments on 3 video datasets show that our proposed model outperforms 10 state-of-the-art dimensionality reduction models. Our theoretical analysis proves that the proposed model is able to recover approximate low-rank representations with a bounded error for clusterable data.

description: A cornerstone of the theory of laser induced incandescence applied to soot aerosols is that the soot is not affected by rapid laser heating. However, it has been demonstrated in the literature that intense laser irradiance typical of ‘high’ or ‘plateau regime’ LII leads to significant modification of the internal structure of soot particles [Vander Wal] and even the formation of new particles from vaporized material [Michelsen]. For moderate laser fluences typical of auto-compensating LII (AC-LII) [Snelling], morphological changes are not observable via high resolution transmission electron microscopy (HR-TEM) [Michelsen]; however, it is still conceivable that the rapid heating of soot aggregates to temperatures in the range of 3000 to 4000 K can influence the internal crystalline structure of soot as well as materials adsorbed on the surface and thus the optical properties of the soot may change as a consequence of the laser heating. Variation of the optical properties of the soot on time scales relevant to LII measurement would have impacts on the interpretation of signal which must be accounted for.

Microscopic toy model for Cavity dynamical Casimir effect

description: We develop a microscopic toy model for Cavity dynamical Casimir effect (DCE), namely, the photon generation from vacuum due to a nonstationary dielectric slab in a fixed single mode cavity. We represent the slab by $N\gg 1$ noninteracting two-level atoms coupled to the field via the standard dipole interaction. We show that the DCE is contained implicitly in the light-matter interaction Hamiltonian when its parameters are externally prescribed functions of time. We also predict several new phenomena, such as saturation of the photon growth due to effective Kerr nonlinearity, generation of pairs of atomic excitations instead of photons ("Inverse DCE") and coherent annihilation of pair of system excitations due to the atomic modulation ("Anti-DCE"). These results are extended to the circuit QED architecture, where similar effects can be implemented with a single qubit providing an alternative way to generate cavity and atom-field entangled states.

MAKING HEADS OR TAILS: AN ICONOGRAPHIC ANALYSIS OF LATE MISSISSIPPIAN RIM-EFFIGY BOWLS IN THE CENTRAL MISSISSIPPI RIVER VALLEY
Creators: name: Azar, Madelaine C
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Symbolically charged ceramic rim-effigy bowls, characterized by figural head and tail adornments, are hallmarks of the Late Mississippian period in the central Mississippi River valley (CMV). Hundreds of whole rim-effigy bowls, most often depicting serpents, birds, or humans, have been collected at sites from southeastern Missouri to northwestern Mississippi. However, a comprehensive iconographic analysis of the CMV rim-effigy bowl corpus – specifically focused on visual style and theme – has never been conducted. A systematic review of the corpus’s imagery suggests that CMV rim-effigy bowls acted as materializations of the Mississippian cosmos, reinforcing the principle of cosmic balance. Further, given discrete concentrations of bowl styles and themes across the region, localized religious collectives – perhaps sodalities – may have produced their own rim-effigy bowls for use during charter rites or ceremonies. More broadly, by reviewing an understudied ceramic corpus, this study furthers understandings of Mississippian art and iconography in the CMV and beyond.
Finite cut-off JT and Liouville quantum gravities on the disk at one loop

description: Within the path integral formalism, we compute the disk partition functions of two dimensional Liouville and JT quantum gravity theories coupled to a matter CFT of central charge $c$, with cosmological constant $Λ$, in the limit $c\rightarrow -\infty$, $|Λ|\rightarrow\infty$, for fixed $Λ/c$ and fixed and finite disk boundary length $\ell$, to leading and first subleading order in the $1/|c|$ expansion. In the case of Liouville theory, we find perfect agreement with the asymptotic expansion of the known exact FZZT partition function. In the case of JT gravity, we obtain the first explicit results for the partition functions at finite cut-off, in the three versions (negative, zero and positive curvature) of the model. Our findings are in agreement with predictions from the recent proposal for a microscopic definition of JT gravity, including the $c\rightarrow -\infty$ expansion of the Hausdorff dimension of the boundary. In the negative curvature case, we also provide evidence for the emergence of an effective Schwarzian description at length scales much greater than the curvature length scale.

description: There are worldwide efforts to search for physics beyond the Standard Model of particle physics. Precision experiments using ultracold neutrons (UCN) require very high intensities of UCN. Efficient transport of UCN from the production volume to the experiment is therefore of great importance. We have developed a method using prestored UCN in order to quantify UCN transmission in tubular guides. This method simulates the final installation at the Paul Scherrer Institute's UCN source where neutrons are stored in an intermediate storage vessel serving three experimental ports. This method allowed us to qualify UCN guides for their intended use and compare their properties.

description: We investigated CeNi9In2 compound, which has been considered as a mixed valence (MV) system. Electrical resistivity vs. temperature variation was analysed in terms of the model proposed by Freimuth for systems with unstable 4f shell. At low temperature the resistivity dependence is consistent with a Fermi liquid state with a contribution characteristic of electron-phonon interaction. Ultraviolet photoemission spectroscopy (UPS) studies of the valence band did not reveal a Kondo peak down to 14 K. A difference of the spectra obtained with photon energies of low and high photoionization cross sections for Ce 4f electrons indicated that 4f states are located mainly close to the Fermi energy. The peaks related to f_{5/2}^1 and f_{7/2}^1 final states cannot be resolved but form a plateau between -0.3 eV and the Fermi energy. X-ray photoemission spectroscopy (XPS) studies were realized for the cerium 3d level. The analysis of XPS spectra within the Gunnarsson-Shönhammer theory yielded a hybridization parameter of 104 meV and non-integer f level occupation, being close to 3. Calculations of partial densities of states were realized by a full potential local orbital (FPLO) method. They confirm that the valence band is dominated by Ni 3d states and are in general agreement with the experiment except for the behavior of f-electrons.

description: Contingency screening for transient stability of large-scale, strongly nonlinear, interconnected power systems is one of the most computationally challenging parts of Dynamic Security Assessment and requires huge resources to perform time-domain simulations-based assessment. To reduce computational cost of time-domain simulations, direct energy methods have been extensively developed. However, these methods, as well as other existing methods, still rely on time-consuming numerical integration of the fault-on dynamics. This task is computationally hard, since possibly thousands of contingencies need to be scanned and thousands of accompanied fault-on dynamics simulations need to be performed and stored on a regular basis. In this paper, we introduce a novel framework to eliminate the need for fault-on dynamics simulations in contingency screening. This simulation-free framework is based on bounding the fault-on dynamics and extending the recently introduced Lyapunov Function Family approach for transient stability analysis of structure-preserving model. In turn, a lower bound of the critical clearing time (CCT) is obtained by solving convex optimization problems without relying on any time-domain simulations. A comprehensive analysis is carried out to validate this novel technique on a number of IEEE test cases.

description: Individuals with autism spectrum disorder (ASD) and co-occurring intellectual disability (ID) may have difficulty both understanding when they are anxious and communicating their anxiety to others. Using a measure that does not require communication to assess anxiety may allow for better accuracy to prepare interventions to help reduce overall anxiety. The purpose of this study is to develop and test whether heart rate can be used to identify anxiety in adults with ASD and ID. A small, pilot study was conducted at a residential facility in North Carolina. Participants had their heart rates measured for 2 weeks using Fitbit watches while staff completed other measures to record periods of participant stress and exertional activity. Analysis revealed changes in heart rate during periods of stress versus exertional or regular activity for the majority of the participants. Analysis also showed that early changes in heart rate preceding documented periods of stress were able to identify and detect experiences of anxiety earlier than observation alone.
Spin-orbit coupling in methyl functionalized graphene

description: We present first-principles calculations of the electronic band structure and spin-orbit effects in graphene functionalized with methyl molecules in dense and dilute limits. The dense limit is represented by a 2$\times$2 graphene supercell functionalized with one methyl admolecule. The calculated spin-orbit splittings are up to $0.6$ meV. The dilute limit is deduced by investigating a large, 7$\times$7, supercell with one methyl admolecule. The electronic band structure of this supercell is fitted to a symmetry-derived effective Hamiltonian, allowing us to extract specific hopping parameters including intrinsic, Rashba, and PIA (pseudospin inversion asymmetry) spin-orbit terms. These proximity-induced spin-orbit parameters have magnitudes of about 1 meV, giant compared to pristine graphene whose intrinsic spin-orbit coupling is about 10 $μ$eV. We find that the origin of this giant local enhancement is the $sp^3$ corrugation and the breaking of local pseudospin inversion symmetry, as in the case of hydrogen adatoms. Also similar to hydrogen, methyl acts as a resonant scatterer, with a narrow resonance peak near the charge neutrality point. We also calculate STM-like images showing the local charge densities at different energies around methyl on graphene.

description: Aims. We investigate the stability of non-isothermal Bonnor-Ebert spheres with a model that includes a self-consistent calculation of the gas temperature. This way we can discard the assumption of equality between the dust and gas temperatures, and study the stability as the gas temperature changes with chemical evolution of the gas. Methods. We use a gas-grain chemical model including a time-dependent treatment of depletion onto grain surfaces, which strongly influences the gas temperature as the main coolant, CO, depletes from the gas. Dust and gas temperatures are solved with radiative transfer. For comparison with previous work, we assume that the cores are deeply embedded in a larger external structure, corresponding to visual extinction $A_{\rm V}^{\rm ext}=10$ mag. Results. We find that the critical non-dimensional radius $ξ_1$ derived here is similar to our previous work where we assumed $T_{\rm dust}=T_{\rm gas}$; the $ξ_1$ values lie below the isothermal critical value $ξ_0\sim6.45$, but the difference is less than 10%. Chemical evolution does not affect notably the stability condition of low-mass cores (<0.75 $M_\odot$). For higher masses the decrease of cooling owing to CO depletion causes substantial temporal changes in the temperature and density profiles of the cores. In the mass range 1-2 $M_\odot$ , $ξ_1$ decreases with chemical evolution, whereas above 3 $M_\odot$ , $ξ_1$ instead increases. We also find that decreasing $A_{\rm V}^{\rm ext}$ increases the gas temperature especially when the gas is chemically old, causing $ξ_1$ to increase with respect to models with higher $A_{\rm V}^{\rm ext}$. The derived $ξ_1$ values are close to $ξ_0$. The density contrast between the core center and edge varies between 8 to 16 depending on core mass and the chemical age of the gas, compared to the constant value $\sim$ 14.1 for the isothermal BES.

description: The workflow satisfiability problem (WSP) asks whether there exists an assignment of authorized users to the steps in a workflow specification that satisfies the constraints in the specification. The problem is NP-hard in general, but several subclasses of the problem are known to be fixed-parameter tractable (FPT) when parameterized by the number of steps in the specification. In this paper, we consider the WSP with user-independent counting constraints, a large class of constraints for which the WSP is known to be FPT. We describe an efficient implementation of an FPT algorithm for solving this subclass of the WSP and an experimental evaluation of this algorithm. The algorithm iteratively generates all equivalence classes of possible partial solutions until, whenever possible, it finds a complete solution to the problem. We also provide a reduction from a WSP instance to a pseudo-Boolean SAT instance. We apply this reduction to the instances used in our experiments and solve the resulting PB SAT problems using SAT4J, a PB SAT solver. We compare the performance of our algorithm with that of SAT4J and discuss which of the two approaches would be more effective in practice.
LANGUAGE EXPERIENCE PREDICTS PRONOUN COMPREHENSION IN IMPLICIT CAUSALITY SENTENCES
Creators: name: Williams, Elyce
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: How does language experience affect processing mechanisms? I test this question by measuring individual patterns of pronoun comprehension in implicit causality contexts, and comparing these with print exposure scores (the Author Recognition Task). Spoken pronoun comprehension was measured in two tasks. In Exp. 1, participants heard implicit clause (IC) stories that ended in a novel word i.e. dax. In Exp. 2, participants heard stories where the pronoun clause was more congruent with the implicit cause interpretation. Participants were asked a comprehension question, which probed pronoun interpretation. In both Exp. 1 and 2, participants tended to identify the implicit cause as the referent, selecting the subject more when it was the implicit cause than not. Critically, ART interacted with Verb bias, such that as ART score increased, participants were more likely to follow a semantic bias. This suggests that print exposure is related to increased implicit cause sensitivity during pronoun comprehension.

description: Healthcare as an industry is recognised as one of the most innovative. Despite heavy regulation, there is substantial scope for new technologies and care models to not only boost patient outcomes but to do so at reduced cost to healthcare systems and consumers. Promoting innovation within national health systems such as the National Health Service (NHS) in the United Kingdom (UK) has been set as a key target for health care professionals and policy makers. However, while the UK has a world-class biomedical research industry, several reports in the last twenty years have highlighted the difficulties faced by the NHS in encouraging and adopting innovations, with the journey from idea to implementation of health technology often taking years and being very expensive, with a high failure rate. This has led to the establishment of several innovation pathways within and around the NHS, to encourage the invention, development and implementation of cost-effective technologies that improve health care delivery. These pathways span local, regional and national health infrastructure. They operate at different stages of the innovation pipeline, with their scope and work defined by location, technology area or industry sector, based on the specific problem identified when they were set up. In this introductory review, we outline each of the major innovation pathways operating at local, regional and national levels across the NHS, including their history, governance, operating procedures and areas of expertise. The extent to which innovation pathways address current challenges faced by innovators is discussed, as well as areas for improvement and future study.

description: We find new sum rules between direct CP asymmetries in $D$ meson decays with coefficients that can be determined from a global fit to branching ratio data. Our sum rules eliminate the penguin topologies $P$ and $PA$, which cannot be determined from branching ratios. In this way we can make predictions about direct CP asymmetries in the standard model without ad hoc assumptions on the sizes of penguin diagrams. We consistently include first-order SU(3)$_F$ breaking in the topological amplitudes extracted from the branching ratios. By confronting our sum rules with future precise data from LHCb and Belle~II one will identify or constrain new-physics contributions to $P$ or $PA$. The first sum rule correlates the CP asymmetries $a_{CP}^{\mathrm{dir}}$ in $D^0\to K^+K^-$, $D^0\to π^+π^-$, and $D^0\to π^0π^0$. We study the region of the $a_{CP}^{\mathrm{dir}}(D^0\to π^+π^-)$--$a_{CP}^{\mathrm{dir}} (D^0\to π^0π^0)$ plane allowed by current data and find that our sum rule excludes more than half of the allowed region at 95\% C.L. Our second sum rule correlates the direct CP asymmetries in $D^+\rightarrow \bar{K}^0 K^+$, $D_s^+\rightarrow K^0 π^+$, and $D_s^+\rightarrow K^+π^0$.

description: In few-qubit systems, the quantum Zeno effect arises when measurement occurs sufficiently frequently that the spins are unable to relax between measurements. This can compete with Hamiltonian terms, resulting in interesting relaxation processes which depend non-monotonically on the ratio of measurement rate to coherent oscillations. While Zeno physics for a single qubit is well-understood, an interesting open question is how the Zeno effect is modified by coupling the measured spin to a non-trivial bulk. In this work, we study the effect of coupling a one-dimensional transverse field Ising to a Zeno spin which lives at the boundary. We find that sharp singularities occur in the boundary relaxation dynamics, which can be tied to the emergence or destruction of edge modes that can be found analytically. Finally, we provide numerical evidence that the dynamical singularities are stable in the presence of integrability-breaking interactions.

description: We consider the single-handed spinor field in interaction with its own gravitational field described by the set of field equations given by Weyl field equations written in terms of derivatives that are covariant with respect to the gravitational connection plus Einstein field equations soured with the energy tensor of the spinor: for the Weyl spinor and the ensuing spacetime of Weyl-Lewis-Papapetrou structure, we will find all exact solutions. The obtained solution for the metric tensor is that of a PP-wave spacetime while the spinor field is a flag-dipole.

Mouthguard Use in NCAA Basketball
Creators: name: Goglia, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Basketball has frequently been demonstrated as a sport with a very high incidence of      dental trauma relative to other sports. Studies have established that mouthguards (MGs) can      reduce the incidence of dental trauma during basketball activities. However, the National      Collegiate Athletic Association (NCAA) has not imposed a mandatory equipment rule for      basketball athletes to wear MGs during gameplay. It is hypothesized that the disconnect      between the evidence-based recommendations to wear MGs during basketball activities and the      low levels of MG compliance is multifactorial. To investigate this hypothesis, a three-part NCAA-focused      study was created. Part One is a nationwide survey of all NCAA basketball programs      current MG practices. Part Two is composed of a prospective NCAA basketball athlete trial to      acquire subjective data on various commercially available MGs. Part Three is a review of the      public health implications for NCAA basketball athletes not wearing MGs.

Supplementary package for thesis: Performance Analysis and Re-Engineering of ExplorViz's Collaboration Mode
Creators: name: Brück, Johannes

description: Supplementary package for thesis: Performance Analysis and Re-Engineering of ExplorViz’s Collaboration Mode A detailed description can be found in the README.md. Abstract Modern software systems are becoming increasingly complex, necessitating advanced tools for comprehension and effective communication among developers. ExplorViz, a Software Visualization as a Service (SVaaS) tool, aids developers in understanding complex software systems. ExplorViz's Collaboration Mode enables interactive exploration of software landscapes in multi-user sessions across various platforms, such as VR or AR. However, the Collaboration Mode has not been tested under high user load, and the underlying architecture is not inherently scalable. This thesis aims to comprehensively analyze the performance of ExplorViz's Collaboration Mode and, based on the results, re-engineer it to better support multi-user sessions with high interaction. To achieve this, we define a benchmark to competitively evaluate our re-engineering effort. The benchmarking analysis revealed the underlying Collaboration Service and high message traffic as primary performance bottlenecks. We have undertaken a re-engineering effort, resulting in a system that enables horizontal scaling, reliable WebSocket connections, and efficient platform-specific messaging to minimize network traffic. Evaluation of the re-engineered system demonstrated high responsiveness and effective resource utilization. Horizontal scaling allows for a successive increase in capacity. However, scalability is somewhat impeded due to the high overhead for server coordination.
Getting the Lorentz transformations without requiring an invariant speed

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The structure of the Lorentz transformations follows purely from the absence of privileged inertial reference frames and the group structure (closure under composition) of the transformations---two assumptions that are simple and physically necessary. The existence of an invariant speed is \textit{not} a necessary assumption, and in fact is a consequence of the principle of relativity (though the finite value of this speed must, of course, be obtained from experiment). Von Ignatowsky derived this result in 1911, but it is still not widely known and is absent from most textbooks. Here we present a completely elementary proof of the result, suitable for use in an introductory course in special relativity.

description: In the mean field approximation of (2+1)-flavor Nambu--Jona-Lasinio model, we strictly derive several sets of coupled equations for the chiral susceptibility, the quark number susceptibility, etc. at finite temperature and quark chemical potential. The critical exponents of these susceptibilities in the vicinity of the QCD critical end point (CEP) are presented in SU(2) and SU(3) cases, respectively. It is found that these various susceptibilities share almost the same critical behavior near the CEP. The comparisons between the critical exponents for the order parameters and the theoretical predictions are also included.

THE PROBLEM OF LOW EXPECTATIONS AND THE PRINCIPLED POLITICIAN
Creators: name: Schmitt, Samuel B
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: “Good games depend on good rules more than good players.” This slogan is an excellent encapsulation of the Public Choice tradition of economist James Buchanan. Public Choice eschews any theory of the ethical politician, choosing instead to focus on the importance of rules which economize on virtue, setting lower moral expectations for politicians. I argue when combined with Buchanan’s theory of becoming, the lowered expectations of Public Choice institutions imply a self-fulfilling prophecy: low expectations are set, and then met. This becomes a weakness for Public Choice only in light of a second observation: good rules sometimes depend upon good players. Public Choice lacks a theory of the ethical politician to address instances of in-period dilemmas between (a) an action which will further the politician’s self-interest and (b) an action which will protect some already accepted, good constitutional principle, but which does not further their self-interest. In response to this problem, I offer a theory of the Principled Politician, an agent characterized by a lexically prior commitment to the constitution.

description: We show the relationship between the mathematical framework used in recent papers by H.C. Rosu, S.C. Mancas and P. Chen (2014) and the second-order confluent supersymmetric quantum mechanics. In addition, we point out several immediate generalizations of the approach taken in the latter references. Furthermore, it is shown how to apply the generalized scheme to the Dirac and to the Fokker-Planck equation.
