description: If all tiles in a tiling are congruent, the tiling is called monohedral. Tiling by convex polygons is called edge-to-edge if any two convex polygons are either disjoint or share one vertex or one entire edge in common. In this paper, we prove that a convex polygon that can generate an edge-to-edge monohedral tiling must be able to generate a periodic tiling.

description: Recently, it has been shown by S.~M. de Carvalho et al. (2014) that the deviations between the degenerate case and observations were already evident for 0.7-0.8 M$_{\odot}$ white dwarfs. Such deviations were related to the neglected effects of finite temperatures on the structure of a white dwarf. Therefore, in this work by employing the Chandrasekhar equation of state taking into account the effects of temperature we show how the total pressure of the white dwarf matter depends on the mass density at different temperatures. Afterwards we construct equilibrium configurations of white dwarfs at finite temperatures. We obtain the mass-radius relations of white dwarfs for different temperatures by solving the Tolman-Oppenheimer-Volkoff equation, and compare them with the estimated masses and radii inferred from the Sloan Digital Sky Survey Data Release 4.

description: Two-photon (2P) microscopy is a cornerstone technique in neuroscience research. However, combining 2P imaging with spectrally arbitrary light stimulation can be challenging due to crosstalk between stimulation light and fluorescence detection. To overcome this limitation, we present a simple and low-cost electronic solution based on an ESP32 microcontroller and a TLC5947 LED driver to rapidly time-interleave stimulation and detection epochs during scans. Implemented for less than $100, our design can independently drive up to 24 arbitrary spectrum LEDs to meet user requirements. We demonstrate the utility of our stimulator for colour vision experiments on the in vivo tetrachromatic zebrafish retina and for optogenetic circuit mapping in Drosophila.

description: Trochanteric bursitis is a musculoskeletal condition caused by inflammation or swelling of the bursae around the greater trochanter. This condition can be a result of repetitive movements (e.g., running) causing microtraumas, blunt trauma, or tendinopathy of neighbouring musculature, resulting in lateral hip pain. Gluteal tendinopathy is a condition which involves the inflammation, degeneration or tears of the gluteus medius or minimus tendons or muscles at or near their insertion into the greater trochanter which also presents as pain and tenderness on the latest aspect of the hip. It is this insertional tendinopathy which may now be considered as the primary underlying cause of lateral hip pain. The precise aetiology of this condition remains unclear; however, it is likely compression of the gluteal tendons in hip adduction may lead to the development of tendon degeneration. The aim of this review is to identify factors that increase the risk of workers developing trochanteric bursitis and gluteal tendinopathy in occupational settings.

description: The development of the $β^-$ based radio-guided surgery aims to extend the technique to those tumours where surgery is the only possible treatment and the assessment of the resection would most profit from the low background around the lesion, as for brain tumours. Feasibility studies on meningioma, glioma, and neuroendocrine tumors already estimated the potentiality of this new treatment. To validate the technique, prototypes of the intraoperative probe required by the technique to detect $β^-$ radiation have been developed. This paper discusses the design details of the device and the tests performed in laboratory. In such tests particular care has to be taken to reproduce the surgical field conditions. The innovative technique to produce specific phantoms and the dedicated testing protocols is described in detail.

The effect of foot type on lower extremity muscle activity and center of pressure
Creators: name: Kupiec, Sean M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The purpose of this study was to examine how foot type and a foot orthotic device (FOD) affect electromyography (EMG) and kinetic data (COP). Thirty-nine individuals (20 with normal and 19 with pronated feet) were tested in overground walking in a pretestposttest design. Results of statistical analyses show no significant differences with regards to onset and duration of the tibialis anterior, peroneus longus, vastus medialis (VMO), and gluteus medius muscles. These results suggest there is no difference in onset and duration, between normal and pronated feet. There was a trend specifically with VMO duration, suggesting a possible shorter duration time with FOD intervention. The COP examination indicated that the normal group had significantly greater COP excursion during the first 50% of stance phase. Also, a similar trend in greater normal foot COP excursion existed between the groups for the entire stance phase.

description: To an exact endofunctor of a triangulated category with a split-generator, the notion of entropy is given by Dimitrov-Haiden-Katzarkov-Kontsevich, which is a (possibly negative infinite) real-valued function of a real variable. In this paper, we propose a conjecture which naturally generalizes the theorem by Gromov-Yomdin, and show that the categorical entropy of a surjective endomorphism of a smooth projective variety is equal to its topological entropy. Moreover, we compute the entropy of autoequivalences of the derived category in the case of the ample canonical or anti-canonical sheaf.

Consideration of the restriction of lateral contraction in the elastic behaviour of cohesive zone models

description: Cohesive zone models do not consider the lateral contraction of adhesive layers under tensile loads. The constraint of the lateral contraction by the adherents which depends on the geometry of the adhesive layer has a major influence on the normal stiffness of the joint. Two methods to improve the accuracy of the stiffness of cohesive zone models of rectangular adhesive layers are proposed in this paper. Both approaches use existing closed-form solutions for rectangular elastic layers between rigid plates. The first assigns an effective stiffness to the entire cohesive zone, the second approach defines a spatially varying stiffness to account for the difference in constraint of the adhesive close to the free surfaces and in the centre of the layer. The accuracy in joint stiffness for cohesive zone models gained by the two methods is tested in two extensive parametric studies considering both rigid and flexible adherents.

Negation in modern Hindi-Urdu: the development of nahII
Creators: name: Lampp, Claire M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: There are three negative particles used for sentential negation in Hindi-Urdu - mat, na, and nahII. The particles mat and na are generally of restricted distribution in the modern language, and their origins are relatively straightforward. The status of the modern general negative particle nahII is more problematic. There are two common explanations for modern Hindi-Urdu nahII: 1) nahII results from the Old Indo-Aryan (OIA) general negative particle na combining with a substantive/existential verb form; 2) nahII results from na combining with the OIA emphatic particle hi. In a recent account Elena Bashir offers support for both explanations. Based on evidence from a modern Hindi corpus and a reexamination of Bashir's work, I conclude that modern Hindi-Urdu nahII likely has its origin only in the existential, thus providing another example in support of William Croft's negation cycle.
Mobility in Crisis: Security, Rights and Responsibility on Guatemala City Buses
Creators: name: Dotson, Rachel
Publisher: name: University of North Carolina at Chapel Hill Graduate School
Year: 2014
Subjects: Ethnology

description: This thesis examines Guatemala City's contemporary "transportation crisis," including the assassination of over 800 bus drivers over the past several years, and state and civil society responses to this crisis. It focuses on the Transmetro, a Bus Rapid Transit system implemented by the municipal government that aims to provide secure transportation, as well as efforts by civil society groups to address violence on buses through campaigns focused on citizenship and human rights. In doing so, it addresses broader questions related to state efforts to resolve insecurity through infrastructure projects and the visions of security underlying such interventions. Since such efforts go beyond the construction of bus lines or the organization of routes to target the attitudes and behaviors of city residents, this paper pays particular attention to how projects to address violence on buses conceptualize rights and responsibilities of both city residents and the municipal state in relation to security.

description: Brain regions are often topographically connected: nearby locations within one brain area connect with nearby locations in another area. Mapping these connection topographies, or 'connectopies' in short, is crucial for understanding how information is processed in the brain. Here, we propose principled, fully data-driven methods for mapping connectopies using functional magnetic resonance imaging (fMRI) data acquired at rest by combining spectral embedding of voxel-wise connectivity 'fingerprints' with a novel approach to spatial statistical inference. We applied the approach in human primary motor and visual cortex, and show that it can trace biologically plausible, overlapping connectopies in individual subjects that follow these regions' somatotopic and retinotopic maps. As a generic mechanism to perform inference over connectopies, the new spatial statistics approach enables rigorous statistical testing of hypotheses regarding the fine-grained spatial profile of functional connectivity and whether that profile is different between subjects or between experimental conditions. The combined framework offers a fundamental alternative to existing approaches to investigating functional connectivity in the brain, from voxel- or seed-pair wise characterizations of functional association, towards a full, multivariate characterization of spatial topography.

description: We describe how to efficiently construct the quantum chemical Hamiltonian operator in matrix product form. We present its implementation as a density matrix renormalization group (DMRG) algorithm for quantum chemical applications in a purely matrix product based framework. Existing implementations of DMRG for quantum chemistry are based on the traditional formulation of the method, which was developed from a viewpoint of Hilbert space decimation and attained a higher performance compared to straightforward implementations of matrix product based DMRG. The latter variationally optimizes a class of ansatz states known as matrix product states (MPS), where operators are correspondingly represented as matrix product operators (MPO). The MPO construction scheme presented here eliminates the previous performance disadvantages while retaining the additional flexibility provided by a matrix product approach; for example, the specification of expectation values becomes an input parameter. In this way, MPOs for different symmetries - abelian and non-abelian - and different relativistic and non-relativistic models may be solved by an otherwise unmodified program.

description: We extend the concepts of quantum complete synchronization and phase synchronization, which are proposed firstly in [Phys. Rev. Lett, 111 103605 (2013)], to more widespread quantum generalized synchronization. The generalized synchronization can be considered as a necessary condition or a more flexible derivative of complete synchronization, and its criterion and synchronization measurement are further proposed and analyzed in this paper. As an example, we consider two typical generalized synchronizations in a designed optomechanical system. Unlike the effort to construct a special coupling synchronization system, we purposefully design extra control fields based on Lyapunov control theory. We find that the Lyapunov function can adapt to more flexible control objectives, which is more suitable for generalized synchronization control, and the control fields can be achieved simply with a time-variant voltage. Finally, the existence of quantum entanglement in different generalized synchronizations is also discussed.

description: In this paper, we tackle a challenging problem inherent in a series of applications: tracking the influential nodes in dynamic networks. Specifically, we model a dynamic network as a stream of edge weight updates. This general model embraces many practical scenarios as special cases, such as edge and node insertions, deletions as well as evolving weighted graphs. Under the popularly adopted linear threshold model and independent cascade model, we consider two essential versions of the problem: finding the nodes whose influences passing a user specified threshold and finding the top-$k$ most influential nodes. Our key idea is to use the polling-based methods and maintain a sample of random RR sets so that we can approximate the influence of nodes with provable quality guarantees. We develop an efficient algorithm that incrementally updates the sample random RR sets against network changes. We also design methods to determine the proper sample sizes for the two versions of the problem so that we can provide strong quality guarantees and, at the same time, be efficient in both space and time. In addition to the thorough theoretical results, our experimental results on $5$ real network data sets clearly demonstrate the effectiveness and efficiency of our algorithms.

description: Bordetella pertussis, the causative agent of whooping cough, is an extracellular, strictly human pathogen. However, it has been shown that B. pertussis cells can escape phagocytic killing and survive in macrophages upon internalization. Our time-resolved RNA-seq data suggest that B. pertussis efficiently adapts to the intramacrophage environment and responds to host bactericidal activities. We show that this adaptive response is multifaceted and, surprisingly, related to the BvgAS two-component system, a master regulator of virulence. Our results show that expression of this regulatory circuit is downregulated upon internalization. Moreover, we demonstrate that the switch to avirulent Bvg- phase augments a very complex process based on the adjustment of central and energy metabolism, cell wall reinforcement, maintenance of appropriate redox and metal homeostasis, and repair of damaged macromolecules. Nevertheless, not all observed effects could be simply attributed to the transition to Bvg- phase, suggesting that additional regulators are involved in the adaptation to the intramacrophage environment. Interestingly, a large number of genes required for metabolism of sulfur were strongly modulated within macrophages. In particular, the mutant lacking two genes encoding cysteine dioxygenases displayed strongly attenuated cytotoxicity toward THP-1 cells. Collectively, our results suggest that intracellular B. pertussis cells have adopted the Bvg- mode to acclimate to the intramacrophage environment and respond to antimicrobial activities elicited by THP-1 cells. Therefore, we hypothesize that the avirulent phase represents an authentic phenotype of internalized B. pertussis cells.

description: Strongly interacting topological states in multi-particle quantum systems pose great challenges to both theory and experiment. Recently, bound states of elementary spin waves (magnons) in quantum magnets have been experimentally observed in quantum Heisenberg chains comprising ultracold Bose atoms in optical lattices. Here, we explore a strongly interacting topological state called topological magnon bound-state in the quantum Heisenberg chain under cotranslational symmetry. We find that the cotranslational symmetry is the key to the definition of a topological invariant for multi-particle quantum states, which enables us to characterize the topological features of multi-magnon excitations. We calculate energy spectra, density distributions, correlations and Chern numbers of the two-magnon bound-states and show the existence of topological protected edge bound-states. Our study not only opens a new prospect to pursue topological magnon bound-states, but also gives insights into the characterization and understanding of strongly interacting topological states.

description: This qualitative study set out to explore how a knowledge of middle school mathematics teachers' preparation to teach culturally diverse students in the past and of their classroom practices in the present can inform multicultural teacher education in the future. In order to answer this question, the following contributing questions were asked: What are teachers' perceived levels of preparedness to teach culturally diverse students? What experiences have supported teachers in becoming prepared to teach culturally diverse students? What do teachers identify as their strengths and weaknesses in practice regarding the teaching of culturally diverse students? How do teachers feel they could have been better prepared through teacher education to teach culturally diverse students? In-depth individual interviews were conducted with a diverse group of seven middle school mathematics teachers. Analysis of the data produced a variety of findings which are discussed along with implications for the field of multicultural teacher education.

description: Microtubules and motor proteins self organize into biologically important assemblies including the mitotic spindle and the centrosomal microtubule array. Outside of cells, microtubule-motor mixtures can form novel active liquid-crystalline materials driven out of equilibrium by ATP-consuming motor proteins. Microscopic motor activity causes polarity-dependent interactions between motor proteins and microtubules, but how these interactions yield such larger-scale dynamical behavior such as complex flows and defect dynamics is not well understood. We develop a multiscale theory for microtubule-motor systems in which Brownian dynamics simulations of polar microtubules driven by motors are used to study microscopic organization and stresses created by motor-mediated microtubule interactions. We identify polarity-sorting and crosslink tether relaxation as two polar-specific sources of active destabilizing stress. We then develop a continuum Doi-Onsager model that captures polarity sorting and the hydrodynamic flows generated by these polar-specific active stresses. In simulations of active nematic flows on immersed surfaces, the active stresses drive turbulent flow dynamics and continuous generation and annihilation of disclination defects. The dynamics follow from two instabilities, and accounting for the immersed nature of the experiment yields unambiguous characteristic length and time scales. When turning off the hydrodynamics in the Doi-Onsager model, we capture formation of polar lanes as observed in the Brownian dynamics simulation.

description: In this project, we will perform secondary analyses of MIDUS data to analyze how emotional responses in older adults with high levels of trait anxiety and heightened threat sensitivity may differ from the predictions of the socioemotional selectivity theory. Specifically, we will examine the relationship between trait anxiety, age, and EBR magnitude during negative images, as well as the relationship between EBR magnitude during negative images and age with negative memory bias . Finally, we will study the interaction between age and anxiety in relation to negative memory bias. The MIDUS dataset provides the opportunity of processing a sample that is fairly large as well as representative of an aging population and contains measures of emotional memory, affective responses as measured by EBR, and trait anxiety. Data from the MIDUS Refresher Project 5 (Neuroscience Project) collected between 2011-2016 during a picture viewing task will be used to extract EBR metrics. A subsequent free recall task of the images in the picture viewing task will be used to measure bias in emotional memory. Demographic information, age, and Spielberger State Trait Anxiety Inventory will be extracted from MIDUS Refresher Project 5.

description: Local roughness distributions (LRDs) are studied in the growth regimes of lattice models in the Kardar-Parisi-Zhang (KPZ) class in 1+1 and 2+1 dimensions and in a model of the Villain-Lai-Das Sarma (VLDS) growth class in 2+1 dimensions. The squared local roughness w_2 is defined as the variance of the height inside a box of lateral size r and the LRD P_r(w_2) is sampled as this box glides along a surface with size L >> r. The variation coefficient C and the skewness S of the distributions are functions of the scaled box size r / xi, where xi(t) is a correlation length. For r > xi, C and S vanish because the LRD converges to a Dirac delta function. This confirms the inadequacy of extrapolations of amplitude ratios to r -> infinity, as proposed in recent works. On the other hand, it highlights the advantage of scaling LRDs by the average instead of scaling by the variance due to the usually higher accuracy of C compared to S. The scaled LRD of the VLDS model is very close to the KPZ one due to the small difference between their variation coefficients and the plateaus of C and S are very narrow due to the slow time increase of xi. These results suggest that experimental LRDs obtained in short growth times and with limited resolution may be inconclusive to determine their universality classes if data accuracy is low and/or data extrapolation to the long time limit is not feasible.

description: We present the results of our work on developing fully integrated devices (photonic dicers) for reformatting multimode light to a diffraction limited pseudo-slit. These devices can be used to couple a seeing-limited telescope point-spread-function to a spectrograph operating at the diffraction limit, thus enabling compact, high-resolution spectrographs that are free of modal-noise.

description: Suppose that F/F+ is a CM extension of number fields in which the prime p splits completely and every other prime is unramified. Fix a place w|p of F. Suppose that rbar : Gal(F-bar/F) -> GL_3(Fp-bar) is a continuous irreducible Galois representation such that rbar|_{Gal(F_w-bar/F_w)} is upper-triangular, maximally non-split, and generic. If rbar is automorphic, and some suitable technical conditions hold, we show that rbar|_{\Gal(F_w-bar/F_w)} can be recovered from the GL_3(F_w)-action on a space of mod p automorphic forms on a compact unitary group. On the way we prove results about weights in Serre's conjecture for rbar, show the existence of an ordinary lifting of rbar, and prove the freeness of certain Taylor-Wiles patched modules in this context. We also show the existence of many Galois representations rbar to which our main theorem applies.

description: In this addendum to Phys. Rev. D 88, no. 1, 013009 (2013), we give results for the electroweak Sudakov corrections in gauge-boson production at large transverse momentum p_T at proton colliders. In order for the results to be easily usable, we provide a simple and accurate parameterization of the corrections as a function of p_T and the center-of-mass energy \sqrt{s}. Additionally, we also discuss the dependence of the electroweak corrections on the rapidity of the produced boson, and comment on the complications that arise in the photon-production case due to isolation requirements

description: 3D silicon detectors, in which the electrodes penetrate the sensor bulk perpendicular to the surface, have recently undergone a rapid development from R\&D over industrialisation to their first installation in a real high-energy-physics experiment. Since June 2015, the ATLAS Insertable B-Layer is taking first collision data with 3D pixel detectors. At the same time, preparations are advancing to install 3D pixel detectors in forward trackers such as the ATLAS Forward Proton detector or the CMS-TOTEM Proton Precision Spectrometer. For those experiments, the main requirements are a slim edge and the ability to cope with non-uniform irradiation. Both have been shown to be fulfilled by 3D pixel detectors. For the High-Luminosity LHC pixel upgrades of the major experiments, 3D detectors are promising candidates for the innermost pixel layers to cope with harsh radiation environments up to fluences of $2\times10^{16}$\,n$_{eq}$/cm$^2$ thanks to their excellent radiation hardness at low operational voltages and power dissipation as well as moderate temperatures. This paper will give an overview on the recent developments of 3D detectors related to the projects mentioned above and the future plans.

description: A Lagrangian formulation of perfect fluid due to a noncanonical three-form field is investigated. The thermodynamic quantities such as energy density, pressure and the four velocity are obtained and then analyzed by comparing with the k-essence scalar field. The nonrelativistic matter due to the generalized three-form field with the equation of state parameter being zero is realized while it might not be possible for the k-essence scalar field. We also found that nonadiabatic pressure perturbations can be possibly generated. The fluid dynamics of the perfect fluid due to the three-form field corresponds to the system in which the number of particles is not conserved. We argue that it is interesting to use this three-form field to represent the dark matter for the classical interaction theory between dark matter and dark energy.

description: Interface physics in oxide heterostructures is pivotal in material's science. Domain walls (DWs) in ferroic systems are examples of naturally occurring interfaces, where order parameter of neighboring domains is modified and emerging properties may develop. Here we show that electric tuning of ferroelastic domain walls in SrTiO3 leads to dramatic changes of the magnetic domain structure of a neighboring magnetic layer (La1/2Sr1/2MnO3) epitaxially clamped on a SrTiO3 substrate. We show that by exploiting the resposiveness of DWs nanoregions to external stimuli, even in absence of any domain contribution, prominent and adjustable macroscopic reactions of neighboring layers can be obtained. We conclude that polar DWs, known to exist in other materials, can be used to trigger tunable responses and may lead to new ways for manipulation of interfacial emerging properties.

Στόχος της είναι η καταγραφή της προϋπάρχουσας κατάστασης, όπως επίσης και οι μελέτες διαμόρφωσης και εξέλιξης. Την σημερινή εποχή, με την οικονομία βασισμένη στον τουρισμό, την ασύστολη χρήση αυτοκινήτων και την αυξανόμενη αστικοποίηση δημιουργούνται ρυθμοί ζωής που προκαλούν την καταστροφή θετικών παραγόντων, όπως οι φυσικοί χώροι και οικονομικές και κοινωνικές δομές, ειδικά ενός μικρού ορεινού χωριού. Στην Νεστάνη, με τα παραδοσιακά οικήματα και τρόπο ζωής, παράγοντες που διατάραξαν την αίσθηση ισορροπίας ήταν η έλλειψη χώρου, το έντονο κυκλοφοριακό πρόβλημα όπως επίσης και η μείωση του μόνιμου πληθυσμού.

Imperial Russia and the Atlantic: An Exploration of Imperial Russia's Naval Stores Trade with Great Britain, France, and Colonial America from 1555-1783

description: This thesis incorporates Imperial Russia into New Atlantic History via its naval stores trade with Great Britain, France, and Colonial America from 1553-1783. Since naval stores such as timber, cordage, tar, pitch, turpentine, hemp, and rosin were used to construct and maintain ships, a comparative analysis of the above three powers' domestic production levels of naval stores with their overall importation levels from Imperial Russia provides a solid basis from which to reevaluate Imperial Russia's relationship not only to the Atlantic Community, but also to one of the most important events in Atlantic history, the American Revolution. Upon doing so it becomes strikingly apparent that all three powers were significantly dependent upon Imperia Russia for naval stores. This demonstrates that Imperial Russia was an integral member of the Atlantic community as well as an influential player in the American Revolution, especially due to its Armed Neutrality Act of 1780.

description: An inhomogeneous fractal set is one which exhibits different scaling behaviour at different points. The Assouad dimension of a set is a quantity which finds the `most difficult location and scale' at which to cover the set and its difference from box dimension can be thought of as a first-level overall measure of how inhomogeneous the set is. For the next level of analysis, we develop a quantitative theory of inhomogeneity by considering the measure of the set of points around which the set exhibits a given level of inhomogeneity at a certain scale. For a set of examples, a family of $(\times m, \times n)$-invariant subsets of the 2-torus, we show that this quantity satisfies a Large Deviations Principle. We compare members of this family, demonstrating how the rate function gives us a deeper understanding of their inhomogeneity.

description: We prove an inequality between the $L^{\infty}$-norm of the contact Hamiltonian of a positive loop of contactomorphims and the minimal Reeb period. This implies that there are no small positive loops on hypertight or Liouville fillable contact manifolds. Non-existence of small positive loops for overtwisted 3-manifolds was proved by Casals-Presas-Sandon in [CPS16]. As corollaries of the inequality we deduce various results. E.g. we prove that certain periodic Reeb flows are the unique minimizers of the $L^\infty$-norm. Moreover, we establish $L^\infty$-type contact systolic inequalities in the presence of a positive loop.
