description: Cover-inclusive Dyck tilings are tilings of skew Young diagrams with ribbon tiles shaped like Dyck paths, in which tiles are no larger than the tiles they cover. These tilings arise in the study of certain statistical physics models and also Kazhdan--Lusztig polynomials. We give two bijections between cover-inclusive Dyck tilings and linear extensions of tree posets. The first bijection maps the statistic (area + tiles)/2 to inversions of the linear extension, and the second bijection maps the "discrepancy" between the upper and lower boundary of the tiling to descents of the linear extension.

description: The phase diagram of Sr_1-xEu_xTiO_3 is determined experimentally by electron paramagnetic resonance and resistivity measurements and analyzed theoretically within the self-consistent phonon approximation as a function of x ([0.03-1.0]). The transition temperature of the structural instability of the system increases nonlinearly to higher temperatures with increasing x. This is interpreted theoretically by a substantial alteration in the dynamics caused by a change in the double-well potential from broad and shallow to narrow and deep.

Lipid and acetate metabolism influence host colonization by the fungal plant pathogen Ustilago maydis
Creators: name: Lambie, Scott Cameron
Publisher: name: University of British Columbia
Year: 2014

description: Ustilago maydis is an obligate fungal pathogen of maize that causes disease known as the common smut of corn. Haploids with compatible mating loci fuse to form a dikaryotic cell type that is filamentous and pathogenic; invasion of the host by this cell type leads to the formation of tumors which contain diploid teliospores. Colonization of the plant presents numerous challenges for U. maydis because the host environment may be limited in nutrients and plant defense responses lead to the creation of toxic molecules such as reactive oxygen species (ROS). Understanding the mechanisms employed by U. maydis to overcome such obstacles is necessary to develop strategies to fight smut disease and protect crops from disease caused by fungal plant pathogens. This study focused on the characterization of a group of genes encoding phospholipases (PLs), enzymes which have been implicated in virulence, morphogenesis and nutrient acquisition of a number of pathogenic fungi. This work included a characterization of one PL, Lip2, which may function to repair ROS-induced damage of membranes that occurs during host colonization. Mutants defective in lip2 were less virulent in maize seedlings, showed sensitivity to H₂O₂ and the drugs chloroquine and quinacrine, and were resistant to ionic stress. A transcriptional profile of a Δlip2 mutant suggested that Lip2 contributes to stress responses and carbon metabolism. Furthermore, lipidomic profiles of the Δlip2 mutant revealed changes in lipid composition that may be linked to the mutant phenotypes. Other aspects of central carbon metabolism were also explored including the utilization of acetate as a carbon source by U. maydis and the role of an ATP-citrate lyase, Acl1, in pathogenesis and fungal development. Acetate had a repressive effect on mating and filamentation, and promoted reduced growth and virulence compared to favorable carbon sources such as glucose. Furthermore, Acl1 was shown to be essential to cause disease and for growth on glucose. Overall, this study reveals potential mechanisms employed by U. maydis during plant colonization to resist the defense response. It also highlights the utility U. maydis as a model system to understand the metabolic and nutritional aspects of fungal phytopathogenesis.

description: In this paper, we give efficient algorithms and lower bounds for solving the heavy hitters problem while preserving differential privacy in the fully distributed local model. In this model, there are n parties, each of which possesses a single element from a universe of size N. The heavy hitters problem is to find the identity of the most common element shared amongst the n parties. In the local model, there is no trusted database administrator, and so the algorithm must interact with each of the $n$ parties separately, using a differentially private protocol. We give tight information-theoretic upper and lower bounds on the accuracy to which this problem can be solved in the local model (giving a separation between the local model and the more common centralized model of privacy), as well as computationally efficient algorithms even in the case where the data universe N may be exponentially large.

Vocal effort and within-speaker coordination in speech production : effects on postural control
Creators: name: Fuhrman, Robert
Publisher: name: University of British Columbia
Year: 2014

description: This thesis probes the joint role of respiration in speech motor control and postural control by examining the effect of increasing the loudness of speech production, or vocal effort, on within-speaker coordination. Specifically, this work tested the dual hypothesis that the functional demands of speech production at increasingly higher levels of vocal effort would result in increasingly rigid coordination across multiple bodily subsystems, and that this entrainment would ultimately affect postural control, resulting in a loss of balance An interactive spontaneous speech task was used to elicit speech at multiple levels of vocal effort by increasing the intended communication distance. Data from acoustic and kinematic measurement domains, including speech, rigid body motion of the head, 2d motion of the body extracted from video, and postural forces and torques measured at the feet, were collected simultaneously. These data were analyzed using a unique collection of techniques for the analysis of non-stationary time-series, which included methods for assessing cross-domain correspondence, system dimensionality, and fluctuation characteristics. The results of these analyses show convergent evidence for both hypotheses. Coordination among kinematic and acoustic measurement domains both strengthens and simplifies at high levels of vocal effort, and evidence of postural instability was found at the highest levels of vocal effort. Subsystem fluctuation characteristics show a direct relationship to the observed effects on coordination, both in terms of their intrinsic properties and in terms of changes due to increased vocal effort. Although this study did not include a direct measure of respiration, these results highlight the necessity of expanding our understanding of respiration’s role in speech motor control, especially insofar as the inevitable crossover between speech and other task domains, such as postural control, is concerned. The methodology used in this study can be straightforwardly expanded towards these ends, and provides a potentially useful in-roads to research in this direction. Even in the absence of a respiratory measure, these results will be of potential interest to clinicians working on the treatment of patients with speech disorders associated with neurological dysfunction, as occur, for example, in Parkinson’s disease.
The role of multiple marks in epigenetic silencing and the emergence of a stable bivalent chromatin state

description: We introduce and analyze a minimal model of epigenetic silencing in budding yeast, built upon known biomolecular interactions in the system. Doing so, we identify the epigenetic marks essential for the bistability of epigenetic states. The model explicitly incorporates two key chromatin marks, namely H4K16 acetylation and H3K79 methylation, and explores whether the presence of multiple marks lead to a qualitatively different systems behavior. We find that having both modifications is important for the robustness of epigenetic silencing. Besides the silenced and transcriptionally active fate of chromatin, our model leads to a novel state with bivalent (i.e., both active and silencing) marks under certain perturbations (knock-out mutations, inhibition or enhancement of enzymatic activity). The bivalent state appears under several perturbations and is shown to result in patchy silencing. We also show that the titration effect, owing to a limited supply of silencing proteins, can result in counter-intuitive responses. The design principles of the silencing system is systematically investigated and disparate experimental observations are assessed within a single theoretical framework. Specifically, we discuss the behavior of Sir protein recruitment, spreading and stability of silenced regions in commonly-studied mutants (e.g., sas2, dot1) illuminating the controversial role of Dot1 in the systems biology of yeast silencing.

description: A region of roughly half of the solar system scale around the star HD 100546 is largely cleared of gas and dust, in contrast to the bright outer disc. However, some material is observed in the immediate vicinity of the star. We investigate how the dust is distributed within and outside the gap, and constrain the disc geometry with mid-infrared interferometric observations using VLTI/MIDI. With baseline lengths of 40m, our long baseline observations are sensitive to the inner few AU from the star, and we combined them with observations at shorter, 15m baselines, to probe emission beyond the gap at up to 20AU from the star. We modelled the mid-infrared emission using radial temperature profiles. Our model is composed of infinitesimal concentric annuli emitting as black bodies, and it has distinct inner and outer disc components. We derived an upper limit of 0.7AU for the radial size of the inner disc, from our longest baseline data. This small dusty disc is separated from the edge of the outer disc by a large, roughly 10AU wide gap. Our short baseline data place a bright ring of emission at 11+-1AU, consistent with prior observations of the transition region between the gap and the outer disc, known as the disc wall. The inclination and position angle are constrained by our data to i=53+-8deg and PA=145+-5deg. Compared to the rim and outer disc geometry this suggests co-planarity. Brightness asymmetry is evident in both short and long baseline data, and it is unequivocally discernible from any atmospheric or instrumental effects. The origin of the asymmetry is consistent with the bright disc wall, which we find to be 1-2AU wide. The gap is cleared of micron-sized dust, but we cannot rule out the presence of larger particles and/or perturbing bodies.

description: The existential k-pebble game characterizes the expressive power of the existential-positive k-variable fragment of first-order logic on finite structures. The winner of the existential k-pebble game on two given finite structures can be determined in time O(n2k) by dynamic programming on the graph of game configurations. We show that there is no O(n(k-3)/12)-time algorithm that decides which player can win the existential k-pebble game on two given structures. This lower bound is unconditional and does not rely on any complexity-theoretic assumptions. Establishing strong k-consistency is a well-known heuristic for solving the constraint satisfaction problem (CSP). By the game characterization of Kolaitis and Vardi our result implies that there is no O(n(k-3)/12)-time algorithm that decides if strong k-consistency can be established for a given CSP-instance.

description: In this article, we are interested in the behaviour of a single ferromagnetic mono-domain particle submitted to an external field with a stochastic perturbation. This model is the first step toward the mathematical understanding of thermal effects on a ferromagnet. In a first part, we present the stochastic model and prove that the associated stochastic differential equation is well defined. The second part is dedicated to the study of the long time behaviour of the magnetic moment and in the third part we prove that the stochastic perturbation induces a non reversibility phenomenon. Last, we illustrate these results through numerical simulations of our stochastic model. The main results presented in this article are the rate of convergence of the magnetization toward the unique stable equilibrium of the deterministic model. The second result is a sharp estimate of the hysteresis phenomenon induced by the stochastic perturbation (remember that with no perturbation, the magnetic moment remains constant).

description: A search for the standard model Higgs boson (H) decaying to a b-quark pair when produced in association with weak vector bosons (V) is reported for the following modes: W(mu,nu)H, W(e,nu)H, Z(mu,mu)H, Z(e,e)H and Z(nu,nu)H. The search is performed in a data sample corresponding to an integrated luminosity of 4.7 inverse femtobarns, recorded by the CMS detector in proton-proton collisions at the LHC with a center-of-mass energy of 7 TeV. No significant excess of events above the expectation from background is observed. Upper limits on the VH production cross section times the H to b-quark pair branching ratio, with respect to the expectations for a standard model Higgs boson, are derived for a Higgs boson in the mass range 110-135 GeV. In this range, the observed 95% confidence level upper limits vary from 3.4 to 7.5 times the standard model prediction; the corresponding expected limits vary from 2.7 to 6.7.

description: Researchers use community-detection algorithms to reveal large-scale organization in biological and social networks, but community detection is useful only if the communities are significant and not a result of noisy data. To assess the statistical significance of the network communities, or the robustness of the detected structure, one approach is to perturb the network structure by removing links and measure how much the communities change. However, perturbing sparse networks is challenging because they are inherently sensitive; they shatter easily if links are removed. Here we propose a simple method to perturb sparse networks and assess the significance of their communities. We generate resampled networks by adding extra links based on local information, then we aggregate the information from multiple resampled networks to find a coarse-grained description of significant clusters. In addition to testing our method on benchmark networks, we use our method on the sparse network of the European Court of Justice (ECJ) case law, to detect significant and insignificant areas of law. We use our significance analysis to draw a map of the ECJ case law network that reveals the relations between the areas of law.

description: Ride-sharing systems contribute to the transition from private cars to a more sustainable utilization of urban traffic infrastructure. To use such systems, travelers indicate their origin and destination via a mobile application, receive a transportation offer, and, if they accept it, are transported to their destination, possibly sharing the vehicle. To ensure long-term acceptance of the service, ride-sharing operators aim to provide a high percentage of travelers with an acceptable transportation offer. To this end, they make use of demand management, i.e., the shaping of demand in its volumes and/or characteristics, and vehicle routing, i.e., routing of the vehicle fleet in order to fulfill transportation requests. In this regard, ride-sharing operators face the challenge that corresponding approaches should ensure both high system performance and fair service conditions, e.g., in terms of traveler fares and driver compensation. The aim of this thesis is therefore to develop soft, i.e. non-monetary, approaches for demand management and vehicle routing in dynamic ride-sharing systems for the benefit of operators, travelers and drivers. To this end, we first focus on implementing the computational framework including state-of-the-art vehicle routing heuristics, as well as on building a comprehensive understanding of controlling demand and its fulfillment in ride-sharing systems. Secondly, we are developing new approaches that focus on demand management and vehicle routing to reduce request cancellations while involving travelers or drivers in the decision-making process. More precisely, we first design heatmaps to support repositioning decisions of idle drivers to balance supply and demand in decentralized ride-sharing systems. Secondly, we design multioptional transportation offers to manage demand while enabling travelers to choose a convenient pickup time from a set of options.

description: A search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 inverse femtobarns recorded by the CMS experiment at the LHC. The search is sensitive to both the standard model Higgs boson and to the neutral Higgs bosons predicted by the minimal supersymmetric extension of the standard model (MSSM). No excess of events is observed in the tau-pair invariant-mass spectrum. For a standard model Higgs boson in the mass range of 110-145 GeV upper limits at 95% confidence level (CL) on the production cross section are determined. We exclude a Higgs boson with m(H) = 115 GeV with a production cross section 3.2 times of that predicted by the standard model. In the MSSM, upper limits on the neutral Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, m(A), sets stringent new bounds in the parameter space, excluding at 95% CL values of tan(beta) as low as 7.1 at m(A) = 160 GeV in the m[h](max) benchmark scenario.

There and Back Again: Generating Repeating Transfers Using Resonant Structures

Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Aerospace engineering not elsewhere classified

description: Many future satellite applications in cislunar space require repeating, periodic transfers that shift away from some operational orbit and eventually return. Resonant orbits are investigated in the Earth-Moon Circular Restricted Three Body Problem (CR3BP) as a mechanism to enable these transfers. Numerous resonant orbit families possess a ratio of orbital period to lunar period that is sufficiently close to an integer ratio and can be exploited to uncover period-commensurate transfers due to their predictable periods. Resonant orbits also collectively explore large swaths of space, making it possible to select specific orbits that reach a region of interest. A framework for defining period-commensurate transfers is introduced that leverages the homoclinic connections associated with an unstable operating orbit to permit ballistic transfers that shuttle the spacecraft to a certain region. Resonant orbits are incorporated by locating homoclinic connections that possess resonant structures, and the applicability of these transfers is extended by optionally linking them to resonant orbits. In doing so, transfers are available for in-orbit refueling/maintenance as well as surveillance/communications applications that depart and return to the same phase in the operating orbit.

description: The energy and entanglement spectrum of fractionally filled interacting topological insulators exhibit a peculiar manifold of low energy states separated by a gap from a high energy set of spurious states. In the current manuscript, we show that in the case of fractionally filled Chern insulators, the topological information of the many-body state developing in the system resides in this low-energy manifold. We identify an emergent many-body translational symmetry which allows us to separate the states in quasi-degenerate center of mass momentum sectors. Within one center of mass sector, the states can be further classified as eigenstates of an emergent (in the thermodynamic limit) set of many-body relative translation operators. We analytically establish a mapping between the two-dimensional Brillouin zone for the Fractional Quantum Hall effect on the torus and the one for the fractional Chern insulator. We show that the counting of quasi-degenerate levels below the gap for the Fractional Chern Insulator should arise from a folding of the states in the Fractional Quantum Hall system at identical filling factor. We show how to count and separate the excitations of the Laughlin, Moore-Read and Read-Rezayi series in the Fractional Quantum Hall effect into two-dimensional Brillouin zone momentum sectors, and then how to map these into the momentum sectors of the Fractional Chern Insulator. We numerically check our results by showing the emergent symmetry at work for Laughlin, Moore-Read and Read-Rezayi states on the checkerboard model of a Chern insulator, thereby also showing, as a proof of principle, that non-Abelian Fractional Chern Insulators exist.

RIPless compressed sensing from anisotropic measurements

description: Compressed sensing is the art of reconstructing a sparse vector from its inner products with respect to a small set of randomly chosen measurement vectors. It is usually assumed that the ensemble of measurement vectors is in isotropic position in the sense that the associated covariance matrix is proportional to the identity matrix. In this paper, we establish bounds on the number of required measurements in the anisotropic case, where the ensemble of measurement vectors possesses a non-trivial covariance matrix. Essentially, we find that the required sampling rate grows proportionally to the condition number of the covariance matrix. In contrast to other recent contributions to this problem, our arguments do not rely on any restricted isometry properties (RIP's), but rather on ideas from convex geometry which have been systematically studied in the theory of low-rank matrix recovery. This allows for a simple argument and slightly improved bounds, but may lead to a worse dependency on noise (which we do not consider in the present paper).

This thesis addresses particular areas where clinical utility data is lacking: First, current methods were validated as clinically useful with plasma viral RNA primarily from patients infected with subtype B HIV-1, the dominant strain in developed countries; however, globally most patients are infected with non-subtype B variants. Secondly, there is insufficient data available with respect to the newest classes of antiretroviral drugs (i.e. CCR5-antagonist and integrase inhibitors). Finally, modern antiretroviral therapies often lead to “undetectable plasma viremia” (i.e. successful ongoing treatment) which make plasma-based genotypic testing impossible; the utility of examining alternative sample types is being actively explored. The overall objective of this thesis is to evaluate genotypic assessment of HIV-1 using standard and “second generation” DNA sequencing methods for guiding clinical decisions in nonconventional sample types. Specifically, it is hypothesized that genotypic assessment of subtype A, C and D HIV-1, plasma viral RNA collected pre-therapy, and viral DNA archived in blood cells are useful predictors of in vitro phenotype and/or clinical outcomes. Chapter 1 and 2 examine the clinical utility of current genotyping approaches when applied to non-subtype-B HIV-1. Results suggest that (1) transmitted genotypic drug resistance predicted small but negative treatment outcomes in non-B infections, and (2) current genotypic tools for predicting viral tropism had poor sensitivities and/or specificities in subtypes A and D, but not C HIV-1. Chapter 3 and 4 examine the clinical utility of current genotypic approaches coupled with alternative sample types. Results suggest that (3) pre-therapy plasma sample tropism results predicted post-therapy post-suppression tropism in 90% of subjects, and (4) viral DNA archived in blood and plasma RNA had similar integrase inhibitor-associated mutations, but mutations in DNA were detected substantially later and were substantially less prevalent. In conclusion, genotypic assessment of HIV-1 using nonconventional sample types is clinically relevant, but has specific limitations. Further methodological research and clinical validation studies are needed to ensure proper interpretation of results.

description: The metric-affine gravity provides a useful framework for analyzing gravitational dynamics since it treats metric tensor and affine connection as fundamentally independent variables. In this work, we show that, a metric-affine gravity theory composed of the invariants formed from non-metricity, torsion and curvature tensors can be decomposed into a theory of scalar, vector and tensor fields. These fields are natural candidates for the ones needed by various cosmological and other phenomena. Indeed, we show that the model accommodates TeVeS gravity (relativistic modified gravity theory), vector inflation, and aether-like models. Detailed analyses of these and other phenomena can lead to a standard metric-affine gravity model encoding scalars, vectors and tensors.

description: We present a novel approach to the construction of new finite algebras and describe the congruence lattices of these algebras. Given a finite algebra $(B_0, \dots)$, let $B_1, B_2, \dots, B_K$ be sets that either intersect $B_0$ or intersect each other at certain points. We construct an \emph{overalgebra} $(A, F_A)$, by which we mean an expansion of $(B_0, \dots)$ with universe $A = B_0 \cup B_1 \cup \cdots \cup B_K$, and a certain set $F_A$ of unary operations that includes mappings $e_i$ satisfying $e_i^2 = e_i$ and $e_i(A) = B_i$, for $0\leq i \leq K$. We explore two such constructions and prove results about the shape of the new congruence lattices $Con(A, F_A)$ that result. Thus, descriptions of some new classes of finitely representable lattices is one contribution of this paper. Another, perhaps more significant contribution is the announcement of a novel approach to the discovery of new classes of representable lattices, the full potential of which we have only begun to explore.

Behind the scenes of sport for development : perspectives of executives of a multinational sport organization

description: Currently, international cricket organizations have mandates to increase cricket participation globally by 1.5 million people. To do this, these organizations are sponsoring cricket-focused international development programs across the globe. This study was inspired by concerns from scholars such as Darnell (2012) about potentially negative outcomes of ‘sport for development and peace’ (SDP) work for targeted populations – and a recognition that little is known about how decisions are made by executives of international sport federations to pursue SDP initiatives. This study explores the international development work of the globally-prominent International Cricket Council (ICC) and the Marylebone Cricket Club (MCC), and is guided by the following research questions: 1) How have decisions been made by high-level executives of global cricket organizations about engaging in development- related work and how are these decisions explained?; 2) How do key decision-makers understand the notion of development and what are their perceptions of development-related issues?; 3) How are development-related goals portrayed to stakeholders and how do these goals align with broader organizational goals?; and 4) What are the benefits of and problems with cricket-related development work as revealed through discussions with key decision-makers? This study is informed by literature on developmentalism, SDP, cricket and globalization, and urban (re)development. Theoretically, postcolonialism is featured because this perspective is concerned with the politics, cultures, and economies of societies living with legacies of colonialism; ongoing impacts of neoliberal forms of development in these societies and; the lived experiences of individuals in contexts where postcolonial forces are especially intense (McEwan, 2009). Nine semi-structured interviews were conducted with executives in ICC and MCC. The results illustrate that: (a) a select group of executives in ICC and MCC make decisions hierarchically, and that decisions reflect organizational mandates; (b), decision- makers tend to be dismissive of critiques of SDP, with notable exceptions; and (c) development-related programs are portrayed differently to different audiences. This study concluded with commentary on the importance of interviewing a range of individuals working in SDP, the sometimes contradictory ways that cricket continues to be implicated in postcolonial relationships, and roles of reflexive decision-makers working in organizations governed by neoliberal policies.

description: We find that collective flow model which can successfully analyze charged particle distributions at AGS and lower SPS (less than 20Gev/n). but fails to analyze that of at RHIC. The tails of distribution of charged particle at RHIC has a jump from the collective flow model calculation as the energy increases. Thermalization Component Model is presented based on collective flow to study the multiplicity distributions at RHIC in this paper. It is realized that the region of phase space of collective flow can reflect that of thermalization region. By comparing the contributions of particle productions from thermalization region at different energies and different centralities, we can deepen our study on the feature of collective movement at RHIC. Keywords: Thermalization, Thermalization component model

description: In 3D reconstruction, the recovery of the calibration parameters of the cameras is paramount since it provides metric information about the observed scene, e.g., measures of angles and ratios of distances. Autocalibration enables the estimation of the camera parameters without using a calibration device, but by enforcing simple constraints on the camera parameters. In the absence of information about the internal camera parameters such as the focal length and the principal point, the knowledge of the camera pixel shape is usually the only available constraint. Given a projective reconstruction of a rigid scene, we address the problem of the autocalibration of a minimal set of cameras with known pixel shape and otherwise arbitrarily varying intrinsic and extrinsic parameters. We propose an algorithm that only requires 5 cameras (the theoretical minimum), thus halving the number of cameras required by previous algorithms based on the same constraint. To this purpose, we introduce as our basic geometric tool the six-line conic variety (SLCV), consisting in the set of planes intersecting six given lines of 3D space in points of a conic. We show that the set of solutions of the Euclidean upgrading problem for three cameras with known pixel shape can be parameterized in a computationally efficient way. This parameterization is then used to solve autocalibration from five or more cameras, reducing the three-dimensional search space to a two-dimensional one. We provide experiments with real images showing the good performance of the technique.

description: It is well-known that the class of lattices generated by Chip Firing games (CFGs) is strictly included in the class of upper locally distributive lattices (ULD). However a necessary and sufficient criterion for this class is still an open question. In this paper we settle this problem by giving such a criterion. This criterion provides a polynomial-time algorithm for constructing a CFG which generates a given lattice if such a CFG exists. Going further we solve the same problem on two other classes of lattices which are generated by CFGs on the classes of undirected graphs and directed acyclic graphs.
