Contested Spaces: The Environment and Environmental Dissidence in the German Democratic Republic, 1980-1990
Creators: name: Ault, Julia Elizabeth
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: This thesis examines the role of environmental activism and dissidence in the last decade of communism in the German Democratic Republic (GDR, East Germany). It contends that rise of discontent over ecological conditions and the regime's corresponding yet insufficient response played a more central role in the revolution of 1989-1990 than has been previously acknowledged. Though environmental groups first coalesced under the aegis of the Protestant Church, concern for the natural environment resonated more broadly within the population. These environmental activists` organizations, protesting primarily local conditions, represented a growing subpublic which both directly and indirectly threatened the authority of the state and its ability to provide for its citizens. Particularly after the nuclear accident at Chernobyl, Ukraine in 1986, environmental issues challenged the legitimacy of the communist regime in East Germany, ultimately taking a more central role in the dissolution of the communist regime in 1989 than has been previously acknowledged.
Antihypertensives Adherence Trajectories and the Association Between Antihypertensive Medications and Fractures Among Older Adults Initiating Therapy
Creators: name: Hargrove, Jennifer

description: Antihypertensive medications reduce the risk of cardiovascular diseases among hypertensive patients. Yet, few older adults are adherent to their antihypertensive therapy. Failure to remain adherent can lead to increased risk of cardiovascular disease, hospitalizations, and mortality. Prior studies have relied on adherence measures that fail to distinguish between medication adherence and persistence. Furthermore, research suggests that antihypertensives are associated with fractures among older adults. However, prior research has found inconsistent results regarding the strength and direction of the association between antihypertensives and fractures. Few studies have examined the initial increased risk of fractures associated with starting antihypertensive therapy, and how the association between antihypertensive and fractures may change over time. We used a 20% random sample of 2007-2013 Medicare Fee-For-Service data to identify beneficiaries initiating antihypertensive therapy between 2008 and 2011. Our primary objectives were: 1) examine whether group based trajectory models (GBTMs) could be used to identify antihypertensive adherence trajectories among older adults initiating therapy, and 2) examine the association between antihypertensive initiation and fractures according to antihypertensive class, duration of use, and fracture type. In our first aim we found that antihypertensive adherence trajectories vary among Medicare beneficiaries and that GBTMs are an effective tool for capturing antihypertensive adherence. We identified six adherence trajectories ranging from beneficiaries who were fully adherent to beneficiaries who never returned after their first prescription. Compared to traditional adherence measures, GBTMs were better at identifying beneficiaries with fluctuating patterns of use. The strongest predictors of non-adherence included initiation with a single antihypertensive class, non-White race, and no prior history of cardiovascular disease. In our second aim we found that the association between antihypertensives and fractures varied according to antihypertensive class, time since initiation, and outcome definition (e.g., falls vs. fractures). Overall, beneficiaries who initiated with angiotensin-receptor blockers had the lowest rate of fractures in the year following initiation. Thiazides were associated with an initial increased rate of falls and fractures, but this association decreased over time. Results suggest clinicians may want to consider different fracture risks when choosing between antihypertensive drug classes, particularly for older adults with a history of falls or fractures.
Single scan MR velocity quantification in ROI by alternating velocity encoding gradient pulse polarity between phase encoding steps
Creators: name: Jonathan, Bremer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: A single scan phase contrast method for quantifying velocity in a region of interest (ROI) containing flowing spins identified prior to scanning is introduced. k-space coverage involves applying positive velocity encoding gradient pulses in acquiring odd phase encoding lines and negative velocity encoding gradient pulses in acquiring even phase encoding lines or vice versa, effectively under sampling flowing spins by a factor of two. A ghost image due to flowing spins in the ROI is formed. The ghost image is located half a field of view away from the ROI in the phase encoding direction. Prior to image acquisition, the field of view in the localizer image is adjusted so that the subsequent ghost image does not overlap with the object being imaged. Velocity quantification is done using image values in ROI and the ghost image. The proposed method is compared to conventional phase contrast in phantom and in vivo. The proposed method reduces scan time considerably.

description: Starting from a fine-scale dissipative particle dynamics (DPD) model of self-motile point particles, we derive meso-scale continuum equations by applying a spatial averaging version of the Irving--Kirkwood--Noll procedure. Since the method does not rely on kinetic theory, the derivation is valid for highly concentrated particle systems. Spatial averaging yields a stochastic continuum equations similar to those of Toner and Tu. However, our theory also involves a constitutive equation for the average fluctuation force. According to this equation, both the strength and the probability distribution vary with time and position through the effective mass density. The statistics of the fluctuation force also depend on the fine scale dissipative force equation, the physical temperature, and two additional parameters which characterize fluctuation strengths. Although the self-propulsion force entering our DPD model contains no explicit mechanism for aligning the velocities of neighboring particles, our averaged coarse-scale equations include the commonly encountered cubically nonlinear (internal) body force density.

description: A puzzling discrepancy exists between the values of the proton charge radius obtained using different experimental techniques: elastic electron-proton scattering and spectroscopy of electronic and muonic hydrogen. The proton radius is defined through the slope of the electric form factor, $G_E(Q^2)$, at zero four-momentum transfer, which is inaccessible in scattering experiments. We propose a novel method for extracting the proton radius from scattering data over a broad $Q^2$ range rather than attempting to directly determine the slope of $G_E$ at $Q^2 = 0$. This method relates the radius of the proton to its transverse charge density, which is the two-dimensional Fourier transform of the Dirac form factor, $F_1(Q^2)$. We apply our method to reanalyze the extensive data obtained by the A1 Collaboration [J. C. Bernauer et al., Phys. Rev. Lett. 105, 242001 (2010)] and extract a radius value, $r_E = 0.889(5)_{\text{stat}}(5)_{\text{syst}}(4)_{\text{model}}~\text{fm}$, that is consistent with the original result. We also provide new parametrizations for the Dirac and Pauli form factors and the transverse charge and magnetization densities of the proton. Our reanalysis shows that the proton radius discrepancy cannot be explained by issues with fitting and extrapolating the A1 data to $Q^2 = 0$.

description: We propose a general scheme for diagnosing interaction-driven topological phases in the weak interaction regime using exact diagonalization (ED). The scheme comprises the analysis of eigenvalues of the point-group operators for the many-body eigenstates and the correlation functions for physical observables to extract the symmetries of the order parameters and the topological numbers of the underlying ground states at the thermodynamic limit from a relatively small size system afforded by ED. As a concrete example, we investigate the interaction effects on the half-filled spinless fermions on the checkerboard lattice with a quadratic band crossing point. Numerical results support the existence of a spontaneous quantum anomalous Hall phase purely driven by a nearest-neighbor weak repulsive interaction, separated from a nematic Mott insulator phase at strong repulsive interaction by a first-order phase transition.

Quantum Horn's lemma, finite heat baths, and the third law of thermodynamics

description: Interactions of quantum systems with their environment play a crucial role in resource-theoretic approaches to thermodynamics in the microscopic regime. Here, we analyze the possible state transitions in the presence of "small" heat baths of bounded dimension and energy. We show that for operations on quantum systems with fully degenerate Hamiltonian (noisy operations), all possible state transitions can be realized exactly with a bath that is of the same size as the system or smaller, which proves a quantum version of Horn's lemma as conjectured by Bengtsson and Zyczkowski. On the other hand, if the system's Hamiltonian is not fully degenerate (thermal operations), we show that some possible transitions can only be performed with a heat bath that is unbounded in size and energy, which is an instance of the third law of thermodynamics. In both cases, we prove that quantum operations yield an advantage over classical ones for any given finite heat bath, by allowing a larger and more physically realistic set of state transitions.

To hell with Christ!, the Gospel, according to Lazarillo: parodia sacra & picaresque signifying on the novel as genre

description: This thesis looks at an anonymously-authored work of early modern Spanish prose fiction, namely La vida de Lazarillo de Tormes, y de sus fortunas y adversidades (The Life of Lazarillo de Tormes: his Fortunes and Misfortunes). It makes the argument that Lazarillo, as a progenitor-text for the picaresque and novelistic traditions, initiates the use of intertextual signifying and the play of the parodic as an imaginative practice that will come to define twentieth century notions of the novel as a generic form with identifiable techniques. Major portions of this essay read parody as it functions within the text, both thematically and structurally; applying Bakhtinian notions of parodia sacra to discuss methodology, form and the construction of meaning within the work.
Dynamic density and spin responses of a superfluid Fermi gas in the BCS-BEC crossover: Path integral formulation and pair fluctuation theory

description: We present a standard field theoretical derivation of the dynamic density and spin linear response functions of a dilute superfluid Fermi gas in the BCS-BEC crossover in both three and two dimensions. The derivation of the response functions is based on the elegant functional path integral approach which allows us to calculate the density-density and spin-spin correlation functions by introducing the external sources for the density and the spin density. Since the generating functional cannot be evaluated exactly, we consider two gapless approximations which ensure a gapless collective mode (Goldstone mode) in the superfluid state: the BCS-Leggett mean-field theory and the Gaussian-pair-fluctuation (GPF) theory. In the mean-field theory, our results of the response functions agree with the known results from the random phase approximation. We further consider the pair fluctuation effects and establish a theoretical framework for the dynamic responses within the GPF theory. We show that the GPF response theory naturally recover three kinds of famous diagrammatic contributions: the Self-Energy contribution, the Aslamazov-Lakin contribution, and the Maki-Thompson contribution. We also show that unlike the equilibrium state, in evaluating the response functions, the linear (first-order) terms in the external sources as well as the induced order parameter perturbations should be treated carefully. In the superfluid state, there is an additional order parameter contribution which ensures that in the static and long wavelength limit, the density response function recovers the result of the compressibility (compressibility sum rule). We expect that the $f$-sum rule is manifested by the full number equation which includes the contribution from the Gaussian pair fluctuations.

The minimum number of states required for a DFA to separate $w$ and $x$ is denoted by $sep(w,x)$. The present paper shows that the difference $|sep(w,x)-sep(w^R,x^R)|$ is unbounded for a binary alphabet; here $w^R$ stands for the mirror image of $w$. This solves an open problem stated in [Demaine, Eisenstat, Shallit, Wilson: Remarks on separating words. DCFS 2011. LNCS vol. 6808, pp. 147-157.]

description: Both metaphysical and practical considerations related to time inversion have intrigued scientists for generations. Physicists have strived to devise and implement time-inversion protocols, in particular different forms of "time mirrors" for classical waves. Here we propose an instantaneous time mirror for quantum systems, i.e., a controlled time discontinuity generating wave function echoes with high fidelities. This concept exploits coherent particle-hole oscillations in a Dirac spectrum in order to achieve population reversal, and can be implemented in systems such as (real or artificial) graphene.

description: Vehicle trajectory prediction tasks have been commonly tackled from two distinct perspectives: either with knowledge-driven methods or more recently with data-driven ones. On the one hand, we can explicitly implement domain-knowledge or physical priors such as anticipating that vehicles will follow the middle of the roads. While this perspective leads to feasible outputs, it has limited performance due to the difficulty to hand-craft complex interactions in urban environments. On the other hand, recent works use data-driven approaches which can learn complex interactions from the data leading to superior performance. However, generalization, \textit{i.e.}, having accurate predictions on unseen data, is an issue leading to unrealistic outputs. In this paper, we propose to learn a "Realistic Residual Block" (RRB), which effectively connects these two perspectives. Our RRB takes any off-the-shelf knowledge-driven model and finds the required residuals to add to the knowledge-aware trajectory. Our proposed method outputs realistic predictions by confining the residual range and taking into account its uncertainty. We also constrain our output with Model Predictive Control (MPC) to satisfy kinematic constraints. Using a publicly available dataset, we show that our method outperforms previous works in terms of accuracy and generalization to new scenes. We will release our code and data split here: https://github.com/vita-epfl/RRB.

description: Wiatowski and Bölcskei, 2015, proved that deformation stability and vertical translation invariance of deep convolutional neural network-based feature extractors are guaranteed by the network structure per se rather than the specific convolution kernels and non-linearities. While the translation invariance result applies to square-integrable functions, the deformation stability bound holds for band-limited functions only. Many signals of practical relevance (such as natural images) exhibit, however, sharp and curved discontinuities and are, hence, not band-limited. The main contribution of this paper is a deformation stability result that takes these structural properties into account. Specifically, we establish deformation stability bounds for the class of cartoon functions introduced by Donoho, 2001.

description: Es wird die Twistorgleichung auf Lorentz-Spin-Mannigfaltigkeiten untersucht. Bekanntermaßen existieren Lösungen der Twistorgleichung auf den pp-Mannigfaltigkeiten, den Lorentz-Einstein-Sasaki Mannigfaltigkeiten und den Fefferman-Räumen. Es wird gezeigt, dass in den kleinen Dimensionen 3,4 und 5 Twistor-Spinoren ohne 'Singularitäten' nur für diese genannten Lorentz-Geometrien vorkommen. Von besonderem Interesse sind Lösungen der Twistorgleichung mit Nullstellen. Es wird die Gestalt der Nullstellenmenge von konformen Vektorfeldern und Twistor-Spinoren beschrieben. Weiterhin wird die Twistorgleichung im Kontext der konformen Cartan-Geometrie formuliert. Als Anwendung werden konform-flache semi-Riemannsche Spin-Mannigfaltigkeiten mit Twistor-Spinoren unter Zuhilfenahme der Holonomiedarstellung der ersten Fundamentalgruppe charakterisiert. Abschließend wird eine Anwendung des Twistorraumes einer Lorentz-4-Mannigfaltigkeit in der Flächentheorie diskutiert. Dabei zeigen wir eine Korrespondenz zwischen holomorphen Kurven im Twistorraum und raumartig immergierten Flächen mit lichtartigem mittlerem Krümmungsvektor. Beispielhaft werden solche Flächen in den Lorentzschen Raumformen der Dimension 4 konstruiert.
description: The twistor equation on Lorentzian spin manifolds is investigated. Known solutions of the twistor equation exist on the pp-manifolds, the Lorentz-Einstein-Sasaki manifolds and the Fefferman spaces. It is shown that in the low dimensions 3,4 and 5 twistor spinors without 'singularities' appear only for these mentioned Lorentzian spin geometries. Solutions of the twistor equation with zeros are of particular interest. The shape of the zero set of conformal vector fields and twistor spinors is described. Moreover, the twistor equation is formulated in the context of conformal Cartan geometry. As an application the conformally flat semi-Riemannian spin spaces with twistor spinors are characterized by the holonomy representation of the first fundamental group. Finally, we discuss an application of the twistor space of a Lorentzian 4-manifold in surface theory. Thereby, we prove a correspondence between holomorphic curves in the twistor space and spacelike immersed surfaces with lightlike mean curvature vector. Exemplary, such surfaces are constructed in the Lorentzian space forms of dimension 4.

description: We consider a new form of theories of gravity in which the action is written in terms of the Ricci scalar and its first and second derivatives. Despite the higher derivative nature of the action, the theory is free from ghost under an appropriate choice of the functional form of the Lagrangian. This model possesses $2+2$ physical degrees of freedom, namely $2$ scalar degrees and $2$ tensor degrees. We exhaust all such theories with the Lagrangian of the form $f(R, (\nabla R)^2, \Box R)$, where $R$ is the Ricci scalar, and then show some examples beyond this ansatz. In course of analysis, we prove the equivalence between these examples and generalized bi-Galileon theories.

Power play: beyond the erotics of masochism in nineteenth-century German literature and philosophy

Year: 2013

description: Power Play: Beyond the Erotics of Masochism in Nineteenth-Century German Literature and Philosophy investigates the genealogy of masochism avant la lettre. Scholarship on masochism has identified it as symptomatic of a late-century crisis of masculinity, synonymous with the erotic and semi-autobiographical writings of Leopold von Sacher-Masoch, the Austrian writer for whom masochism is named. Using a Foucauldian approach to analyzing matrices of power, this project exposes the crucial prehistory of masochism in nineteenth-century German literature and thought, exploring how canonical works of German literature offer alternate genealogies located in discourses on subjectivity, pedagogy, aesthetics, and religion. Calling into question the gender discourses surrounding women in the masochistic dynamic, I compare the submission of Kleist’s titular character in Das Käthchen von Heilbronn with the female dominant in Sacher-Masoch’s Venus im Pelz, showing how both characters subvert social constructions of their identities counter the masculine discourse. The power of self-cultivation found in the German ideology of Bildung and the Bildungsroman genre are explored vis-à-vis the mode of reading and acculturation employed in Goethe’s Wilhelm Meisters Lehrjahre via counter-readings of Novalis’ Heinrich von Ofterdingen and Adalbert Stifter’s Der Nachsommer. Within discourses on the aesthetic, particularly the trope of the suffering artist and the inspiration he derives from suffering, I compare the German artist in Venus im Pelz with artists in Heinrich Wackenroder’s Herzensergiessungen eines kunstliebenden Klosterbruders, and Gottfried Keller’s Der grüne Heinrich, to consider the connection between masochistic suffering and the transcendence of the suprasensual in the sublime. Finally, I engage with two religious discourses in Sacher-Masoch’s text. First, the hagiography, providing inspiration through descriptions of suffering and transcendence, is critiqued through secular texts like Büchner’s Lenz. Second, I look at the confession, identified by Foucault as critical to the nineteenth-century production of knowledge, and how it is critiqued and subverted through anonymous pornographic texts, sepecifically Lina’s aufrichtige Bekenntnisse, Schwester Monika, and Bekenntnisse einer Giftmischerin, which appropriate and oppose the confessional form. At stake is an analysis of power that directs our attention away from a purely erotic understanding of masochism to something that simultaneously participates in and critiques these discourses of power.

We find that (i) for a single active cavity, significant enhancement can be achieved for the higher-order sidebands, including the transmission rate and the group delay; (ii) for active- passive-coupled cavities, hundreds of microsecond of optical delay or advance are attainable for the nonlinear sideband pulses in the parity-time-symmetric regime. The active higher-order OMIT effects, as firstly revealed here, open up the way to make a low-power optomechaical amplifier, which can amplify both the strength and group delay of not only the probe light but also its higher-order sidebands.

description: BACKGROUND: The aim of this study was to evaluate retrospective data to investigate the effects of cardiac rehabilitation on health markers and performance outcomes among diabetic and nondiabetic patients with coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI). METHODS: One hundred and ninety-seven patients with PCI and CABG, who attended phase 2 cardiac rehabilitation, were included in the study. Patient data was split by cardiac diagnosis, diabetes category, number of sessions attended, and time. The Duke Activity Score Index and Patient Health Questionnaire-9 questionnaires and measurements for total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides, and if diabetic, A1c and fasting blood glucose were taken at baseline and upon completion of the program. RESULTS: High-density lipoprotein and the Duke Activity Score Index questionnaire significantly increased from pre- to post-testing. Diastolic blood pressure and the Patient Health Questionnaire-9 significantly decreased from pre- to post-testing. Time, session group, diabetes category, and admission event influenced the decrease in total cholesterol and low-density lipoprotein for the 25-36 session PCI, nondiabetic group. Time and session group influenced the decrease triglycerides for all 12-24 session groups. Diabetics had a significant interaction for A1c. No significant interactions were found for systolic blood pressure and body weight. For fasting blood glucose, time, session group, and admission event influenced the decrease of glucose for the PCI group with diabetes. CONCLUSION: Cardiac Rehabilitation resulted in significant improvements in the lipid panel, diastolic blood pressure, and questionnaires regardless of the number of sessions attended. However, no significant benefits for systolic blood pressure were observed.

Monte Carlo Strategies in Option Pricing for SABR Model
Creators: name: Yin, Leicheng
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Option pricing problems have always been a hot topic in mathematical finance. The SABR model is a stochastic volatility model, which attempts to capture the volatility smile in derivatives markets. To price options under SABR model, there are analytical and probability approaches. The probability approach i.e. the Monte Carlo method suffers from computation inefficiency due to high dimensional state spaces. In this work, we adopt the probability approach for pricing options under the SABR model. The novelty of our contribution lies in reducing the dimensionality of Monte Carlo simulation from the high dimensional state space (time series of the underlying asset) to the 2-D or 3-D random vectors (certain summary statistics of the volatility path).

description: In interpretation of remote sensing images, it is possible that some images which are supplied by different sensors become incomprehensible. For better visual perception of these images, it is essential to operate series of pre-processing and elementary corrections and then operate a series of main processing steps for more precise analysis on the images. There are several approaches for processing which are depended on the type of remote sensing images. The discussed approach in this article, i.e. image fusion, is the use of natural colors of an optical image for adding color to a grayscale satellite image which gives us the ability for better observation of the HR image of OLI sensor of Landsat-8. This process with emphasis on details of fusion technique has previously been performed; however, we are going to apply the concept of the interpolation process. In fact, we see many important software tools such as ENVI and ERDAS as the most famous remote sensing image processing tools have only classical interpolation techniques (such as bi-linear (BL) and bi-cubic/cubic convolution (CC)). Therefore, ENVI- and ERDAS-based researches in image fusion area and even other fusion researches often dont use new and better interpolators and are mainly concentrated on the fusion algorithms details for achieving a better quality, so we only focus on the interpolation impact on fusion quality in Landsat-8 multispectral images. The important feature of this approach is to use a statistical, adaptive, and edge-guided interpolation method for improving the color quality in the images in practice. Numerical simulations show selecting the suitable interpolation techniques in MRF-based images creates better quality than the classical interpolators.

description: The human papillomavirus (HPV) vaccination literature supports the role of culture on African-Americans’ HPV vaccination acceptance. However, the evidence supporting the role of culture on this health behavior is limited. Few studies examine the influence of culture on HPV vaccination acceptance among African-Americans using theoretical frameworks grounded in culture, and few studies examine the influence of culture from the perspective of adolescent females. Therefore, using a dyadic approach, this dissertation explored the role of culture on African-American parents’ and their adolescent daughters’ (12 to 17 years old) HPV vaccination acceptance using both the PEN-3 cultural model and the Health Belief Model. Grounded theory techniques and quantitative descriptive statistics were used to explore the cultural factors that influence the HPV vaccine acceptance of 29 African-American parent-daughter dyads (n = 30 parents; n = 34 daughters) residing in the Southeastern and Northeastern United States. This dissertation’s findings provide evidence of the role of culture on African-American parents’ and their adolescent daughters’ HPV vaccine acceptance, and suggest the need for future research to use a culturally empowering lens to better understand African-American parents’ and adolescent daughters’ cervical cancer prevention health behaviors. Additionally, the findings support the usefulness of using a culture-centered theory to explore culture-related factors that influence the HPV vaccine acceptance of African-American parents and daughters. Incorporating a dyadic approach was also useful for understanding how cultural factors that influence African-American parents’ and daughters’ perceptions and health behaviors may be transmitted among families, kinship networks, and the community. The findings from this dissertation elucidate new areas that may potentially inform the development of culturally appropriate interventions to advance the field of cervical cancer prevention research.

description: We study the possible interpretation of the "universal constants" by the classification of J.~M.~Lévy-Leblond. $\hbar$ and $c$ are the most common example of constants of this type. Using Fock's principle of the relativity w.r.t. observation means, we show that both $c$ and $\hbar$ can be viewed as manifestations of certain relativity. We also show that there is a possibility to interpret the Boltzmann's constant in a similar way, and make some comments about the relativistic interpretation of the constant spacetime curvature and gravitational constant $G$.

description: We investigate the possibility of searching the lepton-flavor-violating (LFV) $τ\rightarrow μγ$ rare decay at the Super Charm-Tau Factory (CTF). By comparing the kinematic distributions of the LFV signal and the standard model (SM) background, we develop an optimized event selection criteria which can significantly reduce the background events. It is concluded that new $2 σ$ upper limit of about $1.9 \times 10^{-9}$ on $Br(τ\rightarrow μγ)$ can be obtained at the CTF, which is beyond the capability of Super-B factory in searching $τ$ lepton rare decay. Within the framework of the scalar leptoquark model, a joint constraint on $λ_1 λ_2$ and $M_{LQ}$ can be derived from the upper bound on $Br(τ\rightarrow μγ)$. With $1000~ fb^{-1}$ data expected at the CTF, we get $λ_1λ_2 < 7.2 \times 10^{-2}~(M_{LQ} = 800~ {\rm GeV})$ and $M_{LQ} > 900~{\rm GeV}~(λ_1 λ_2 = 9 \times 10^{-2})$ at $95\%$ confidence level (C.L.).

description: We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, $a_{\mu}^{\rm HVP}$, in the so-called short and intermediate time-distance windows, $a_{\mu}^{\rm SD}$ and $a_{\mu}^{\rm W}$. We employ gauge ensembles produced by the Extended Twisted Mass Collaboration (ETMC) with $N_f = 2 + 1 + 1$ flavours of Wilson-clover twisted-mass quarks with masses of all the dynamical quark flavours tuned close to their physical values. The simulations are carried out at three values of the lattice spacing equal to $\simeq 0.057, 0.068$ and $0.080$ fm with spatial lattice sizes up to $L \simeq 7.6$~fm. For the short distance window we obtain $a_\mu^{\rm SD} = 69.27\,(34) \cdot 10^{-10}$, in agreement with the dispersive determination based on experimental $e^+ e^-$ data. For the intermediate window we get instead $a_\mu^{\rm W} = 236.3\,(1.3) \cdot 10^{-10}$, which is consistent with recent determinations by other lattice collaborations, but disagrees with the dispersive determination at the level of $3.6\,\sigma$.
Quenched tail estimate for the random walk in random scenery and in random layered conductance

description: We discuss the quenched tail estimates for the random walk in random scenery. The random walk is the symmetric nearest neighbor walk and the random scenery is assumed to be independent and identically distributed, non-negative, and has a power law tail. We identify the long time aymptotics of the upper deviation probability of the random walk in quenched random scenery, depending on the tail of scenery distribution and the amount of the deviation. The result is in turn applied to the tail estimates for a random walk in random conductance which has a layered structure.

The LIV Card Sort: an investigation of use relative to cognitive and linguistic variables

description: Self-determination model, Life Participation Approach to Aphasia, and WHO's International Classification of Functioning are important concepts in developing functional goals with meaningful outcomes for people in rehabilitation after stroke. Individuals with aphasia after stroke can have a difficult time expressing their needs and preferences regarding rehabilitation, an important aspect of these models. The Life Interests and Values (LIV) Card Sort designed for people with aphasia to communicate information important for treatment planning. Individuals with aphasia secondary to stroke can have co-occurring cognitive deficits that can interfere with ability to perform some tasks. This study investigated the relationship between five individuals' cognitive-linguistic profiles and ability to complete the LIV Card Sort (measured with behavioral variables like number of clinician cues). Results of the study suggest that there is a relationship between cognitive-linguistic profile and behavioral variables, yet these deficits do not seem to limit any person from using the Cards.

π-flux Dirac bosons and topological edge excitations in a bosonic chiral p-wave superfluid

description: We study the topological properties of elementary excitations in a staggered $p_x \pm i p_y$ Bose-Einstein condensate realized in recent orbital optical lattice experiments. The condensate wave function may be viewed as a configuration space variant of the famous $p_x+ ip_y$ momentum space order parameter of strontium ruthenate superconductors. We show that its elementary excitation spectrum possesses Dirac bosons with $π$ Berry flux. Remarkably, if we induce a population imbalance between the $p_x+ip_y$ and $p_x-ip_y$ condensate components, a gap opens up in the excitation spectrum resulting in a nonzero Chern invariant and topologically protected edge excitation modes. We give a detailed description on how our proposal can be implemented with standard experimental technology.

Primary failure of eruption: further characterization of a rare eruption disorder
Creators: name: Koehler, Karen E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Primary failure of eruption (PFE) is a rare condition that leads to spectacular posterior open bites and does not respond to orthodontic treatment. Records from 97 patients with posterior open bite were analyzed. Based on key characteristics, subjects were classified as having PFE, indeterminate failure of eruption (IFE), and mechanical failure of eruption (MFE). Results showed that PFE affects mostly posterior teeth, affects all teeth distal to the first affected tooth, often presents with a cleared eruption path that the tooth fails to follow, and appears to have two forms. Type I exhibits a similar lack of eruption potential of affected teeth, and Type II has a varied eruption potential. This study also supports the genetic etiology of PFE which is likely due to a defect in a tooth-specific gene product. Differentiation between PFE and ankylosis is key to determining prognosis for orthodontic treatment and requires adequate longitudinal data.
