description: The performance, reliability, and ubiquity of automatic speech recognition systems has flourished in recent years due to steadily increasing computational power and technological innovations such as hidden Markov models, weighted finite-state transducers, and deep learning methods. One problem which plagues speech recognition systems, especially those that operate offline and have been trained on specific in-domain data, is the deleterious effect of noise on the accuracy of speech recognition. Historically, robust speech recognition research has focused on traditional noise types such as additive noise, linear filtering, and reverberation. This thesis describes the effects of nonlinear dynamic range compression on automatic speech recognition and develops a number of novel techniques for characterizing and counteracting it. Dynamic range compression is any function which reduces the dynamic range of an input signal. Dynamic range compression is a widely-used tool in audio engineering and is almost always a component of a practical telecommunications system. Despite its ubiquity, this thesis is the first work to comprehensively study and address the effect of dynamic range compression on speech recognition. More specifically, this thesis treats the problem of dynamic range compression in three ways: (1) blind amplitude normalization methods, which counteract dynamic range compression when its parameter values allow the function to be mathematically inverted, (2) blind amplitude reconstruction techniques, i.e., declipping, which attempt to reconstruct clipped segments of the speech signal that are lost through non-invertible dynamic range compression, and (3) matched-training techniques, which attempt to select the pre-trained acoustic model with the closest set of compression parameters. All three of these methods rely on robust estimation of the dynamic range compression distortion parameters. Novel algorithms for the blind prediction of these parameters are also introduced. The algorithms' quality is evaluated in terms of the degree to which they decrease speech recognition word error rate, as well as in terms of the degree to which they increase a given speech signal's signal-to-noise ratio. In all evaluations, the possibility of independent additive noise following the application of dynamic range compression is assumed.

description: Let End(V) denote the ring of all linear transformations of an arbitrary k-vector space V over a field k. We define a subset X of End(V) to be "triangularizable" if V has a well-ordered basis such that X sends each vector in that basis to the subspace spanned by basis vectors no greater than it. We then show that an arbitrary subset of End(V) is "strictly" triangularizable (defined in the obvious way) if and only if it is topologically nilpotent. This generalizes the theorem of Levitzki that every nilpotent semigroup of matrices is triangularizable. We also give a description of the triangularizable subalgebras of End(V), which generalizes of a theorem of McCoy classifying triangularizable algebras of matrices over algebraically closed fields.

description: It has been shown that in larger than four space-time dimensions, soft factors that relate the amplitudes with a soft photon or graviton to amplitudes without the soft particle also determine the low frequency radiative part of the electromagnetic and gravitational fields during classical scattering. In four dimensions the S-matrix becomes infrared divergent making the usual definition of the soft factor ambiguous beyond the leading order. However the radiative parts of the electromagnetic and gravitational fields provide an unambiguous definition of soft factor in the classical limit up to the usual gauge ambiguity. We show that the soft factor defined this way develops terms involving logarithm of the energy of the soft particle at the subleading order in the soft expansion.

description: Solar wind fluctuations, such as magnetic field or velocity, show power law power spectra suggestive both of an inertial range of intermittent turbulence (with $\sim -5/3$ exponent) and at lower frequencies, of fluctuations of coronal origin (with $\sim -1$ exponent). The ULYSSES spacecraft spent many months in the quiet fast solar wind above the Sun's polar coronal holes in a highly ordered magnetic field. We use statistical analysis methods such as the generalized structure function (GSF) and extended self-similarity (ESS) to quantify the scaling of the moments of the probability density function of fluctuations in the magnetic field. The GSFs give power law scaling in the ``$f^{-1}$'' range of the form $\simτ^{ζ(m)}$, but ESS is required to reveal scaling in the inertial range, which is of the form $\sim [g(τ)]^{ζ(m)}$. We find that $g(τ)$ is independent of spacecraft position and $g(τ)\simτ^{-log_{10}(\tildeλτ)}$. The ``$f^{-1}$'' scaling fluctuates with radial spacecraft position. This confirms that, whereas the ``$f^{-1}$'' fluctuations are directly influenced by the corona, the inertial range fluctuations are consistent with locally evolving turbulence, but with an ``envelope'' $g(τ)$, which captures the formation of the quiet fast solar wind.

description: We study the Turaev-Viro invariant as the Euclidean Chern-Simons-Witten gravity partition function with positive cosmological constant. After explaining why it can be identified as the partition function of 3-dimensional gravity, we show that the initial data of the TV invariant can be constructed from the duality data of a certain class of rational conformal field theories, and that, in particular, the original Turaev-Viro's initial data is associated with the $A_{k+1}$ modular invariant WZW model. As a corollary we then show that the partition function $Z(M)$ is bounded from above by $Z((S^2\times S^1)^{\sharp g}) =(S_{00})^{-2g+2}\sim Λ^{-\frac{3g-3}{2}}$, where $g$ is the smallest genus of handlebodies with which $M$ can be presented by Hegaard splitting. $Z(M)$ is generically very large near $Λ\sim +0$if $M$ is neither $S^3$ nor a lens space, and many-wormholeconfigurations dominate near $Λ\sim +0$ in the sense that $Z(M)$ generically tends to diverge faster as the ``number of wormholes'' $g$ becomes larger.

description: Community colleges are integral to American education because they provide accessible education for all citizens (Jacobson, LaLonde, & Sullivan, 2005). There is a growing need, however, to improve upon the educational practices of these colleges so that more students can successfully earn degrees. Despite the many opportunities that higher education affords, a large percentage of students are underprepared for college-level coursework and are not able to complete degree requirements. Remedial coursework is available to those who need basic skills training, but the additional time and tuition required to complete these programs can actually deter student engagement and decrease their motivation to earn degrees. This three-paper dissertation, conducted with an urban community college student sample, utilizes archival and self-report data sets to investigate the impact of a college-wide intervention aimed at students in need of remedial classes, the impact of demographic factors on performance, and the effect of psychological factors on performance. In the first paper, I examine the effectiveness of a course designed to prepare students in remedial education courses for college work. In the second paper, I investigate the relationship between various demographic factors and student GPA and retention. In the third paper, I focus on the relationships between psychological factors and student GPA and retention. Results indicated that the metacognitive courses did not impact GPA or retention, yet demographic and psychological factors do impact these two outcome variables. These results aid in understanding the elements that contribute to community college student success so that education and organizational behavior researchers can develop interventions based on empirical evidence.

title: Principled Approach to Natural Language Generation
Creators: name: Puzikov, Yevgeniy
Publisher: name: UNSPECIFIED

description: The research field of Natural Language Generation offers practitioners a wide range of techniques for producing texts from a variety of data types. These techniques find their way into various real- world applications and help many people to automate time-consuming tasks of text production in many areas. At the moment, the design and evaluation of text generation approaches is largely empirical. Many systems are being developed to solve one particular task and work on a single data type, which makes it hard to compare the approach to any other technique and critically evaluate its performance. Some systems employ complex machine learning algorithms to learn rich data representations and perform joint modeling of the steps involved in the process of text generation. Such approaches offer an attractive trade-off between the development costs and output quality, but often lack transparency in terms of the reasoning about the behavior of the system. The number of the proposed approaches constantly grows, but the methodology lags behind and sometimes fails to solicit a better understanding of which approaches work, and the reasons for it. In this thesis we present our view on the task of text production from a methodological point of view. We analyze the existent scientific literature, examine common text generation approaches and the established evaluation protocols. We further propose a principled view on the problem: we break it into components, examine their interaction and develop a set of recommendations which are envisioned to offer assistance during the design or analysis of a study. We further conduct a range of experiments to test this framework in several text generation tasks. First, we show that task specification analysis sometimes allows one to solve the problem at hand with very simple techniques, without resorting to the complex machinery of advanced statistical learning methods. We further demonstrate the potential of the developed framework to find discrepancies in the established evaluation protocols. We show that sometimes neither metric, nor conventional human evaluation is sufficient to draw conclusions about system performance. We demonstrate how a system can fit the data to achieve high automatic metric scores, while falling short in terms of actual output quality. Finally, we use the framework to demonstrate how one can develop effective text generation systems without sacrificing the transparency of the inner working logic, making the developed systems both accurate and reliable.

description: We present a numerical study of the dynamical effects following a sudden change of the transverse trapping frequency in an elongated Bose-Einstein condensate, which induces periodic oscillations of the radial density. At early times, we observe an exponential growth of the number of resonant longitudinal phonons, in agreement with the predictions of the Bogoliubov-de Gennes treatment. We then observe an ordered sequence of phenomena induced by the nonlinearities of the system. The first is a loss of the nonseparability of the resonant phonon pairs. This is followed by the saturation of the exponential growth and a strong depletion of condensed atoms. Notably, these effects are well-described by effective 1D dynamics, and are hardly affected by the damping of the radial oscillations. Finally, the atomic spectrum becomes broad, featureless and almost incoherent, in agreement with experimental results. The link between this sequence of events and the preheating scenario in inflationary cosmology is striking, as is the similarity of techniques used to study them.

description: This study presents a simplified approach to studying the dynamics of global texture collapse. We derive equations of motion for a spherically symmetric field configuration using a two parameter ansatz. Then we analyse the effective potential for the resulting theory to understand possible trajectories of the field configuration in the parameter space of the ansatz. Numerical results are given for critical winding and collapse time in spatially flat non-expanding, and flat expanding universes. In addition, the open non-expanding and open-expanding cases are studied.

description: In this work, we conduct experiments comparing OAI-PMH with ResourceSync along a set of dimensions, scenarios and implementation setups. Our results are the first to disclose that OAI-PMH performance varies significantly across platforms, explaining why it is difficult for aggregators to stay synchronised with data providers. We also provide evidence showing that ResourceSync is, if applied in suitable synchronisation mode, substantially faster and more effective in synchronisation of resources and puts also lower load on the data providers than OAI-PMH. By comparing the performance of OAI-PMH with ResourceSync on the task of metadata harvesting (small files), i.e. the most challenging scenario for ResourceSync, we demonstrate that ResourceSync performs up to about 10x faster in the Batch mode than an average OAI-PMH repository.

description: Increasing urbanization offers a unique opportunity to study adaptive responses to rapid environmental change. Numerous studies have demonstrated phenotypic divergence between urban and rural organisms. However, comparing the direction and magnitude of natural selection between these environments has rarely been attempted. Using seven years of monitoring of nest-box breeding of great tits (Parus major) in the city of Montpellier and in a nearby oak forest, we find phenotypic divergence in four morphological and two life-history traits between urban and forest birds. We then measure reproductive selection on these traits, and compare selection between the habitats. Urban birds had significantly smaller morphological features than their rural counterparts, with a shorter tarsus, lower body mass, and smaller wing and tail lengths relative to their overall body size. While urban female tarsus length was under stabilizing selection, and forest males show positive selection for tarsus length and negative selection for body mass, selection gradients were significantly divergent between habitats only for body mass. Urban great tits also had earlier laying dates and smaller clutches. Surprisingly, we found selection for earlier laying date in the forest but not in the city. Conversely, we detected no linear selection on clutch size in the forest, but positive selection on clutch size in the urban habitat. Overall, these results do not support the hypothesis that contemporary reproductive selection explains differences in morphology and life history between urban- and forest-breeding great tits. We discuss how further experimental approaches will help confirm whether the observed divergence is maladaptive while identifying the environmental drivers behind it.

description: Using the time-dependent Bogoliubov approach, we study adiabaticity for a two-component Bose-Einstein condensate in a 3D time-dependent optical lattice with unit filling, in the superfluid and weakly interacting regime. We show that raising the lattice potential height can couple the ground state of the Bogoliubov Hamiltonian to excited states with two quasiparticles of opposite quasi-momenta. In the symmetric case for interactions and density in the two components these represent sound waves where the two components oscillate out of phase. We find an analytic expression of the adiabatic time, its dependence on the fraction of atoms in each component and its scaling with the system size.

description: The first confirmed mechanism for aluminum (Al) resistance in plants is encoded by the wheat (Triticum aestivum) gene, TaALMT1, on chromosome 4DL. TaALMT1 controls the Al-activated efflux of malate from roots, and this mechanism is widespread among Al-resistant genotypes of diverse genetic origins. This study describes a second mechanism for Al resistance in wheat that relies on citrate efflux. Citrate efflux occurred constitutively from the roots of Brazilian cultivars Carazinho, Maringa, Toropi, and Trintecinco. Examination of two populations segregating for this trait showed that citrate efflux was controlled by a single locus. Whole-genome linkage mapping using an F 2 population derived from a cross between Carazinho (citrate efflux) and the cultivar EGA-Burke (no citrate efflux) identified a major locus on chromosome 4BL, Xcec, which accounts for more than 50% of the phenotypic variation in citrate efflux. Mendelizing the quantitative variation in citrate efflux into qualitative data, the Xcec locus was mapped within 6.3 cM of the microsatellite marker Xgwm495 locus. This linkage was validated in a second population of F2:3 families derived from a cross between Carazinho and the cultivar Egret (no citrate efflux). We show that expression of an expressed sequence tag, belonging to the multidrug and toxin efflux (MATE) gene family, correlates with the citrate efflux phenotype. This study provides genetic and physiological evidence that citrate efflux is a second mechanism for Al resistance in wheat. © 2008 American Society of Plant Biologists.

description: An effective string theory in physically relevant cosmological and black hole space times is reviewed. Explicit computations of the quantum string entropy, partition function and quantum string emission by black holes (Schwarzschild, rotating, charged, asymptotically flat, de Sitter dS and AdS space times) in the framework of effective string theory in curved backgrounds provide an amount of new quantum gravity results as: (i) gravitational phase transitions appear with a distinctive universal feature: a square root branch point singularity in any space time dimensions. This is of the type of the de Vega - Sanchez transition for the thermal self-gravitating gas of point particles. (ii) There are no phase transitions in AdS alone. (iii) For $dS$ background, upper bounds of the Hubble constant H are found, dictated by the quantum string phase transition.(iv) The Hawking temperature and the Hagedorn temperature are the same concept but in different (semiclassical and quantum) gravity regimes respectively. (v) The last stage of black hole evaporation is a microscopic string state with a finite string critical temperature which decays as usual quantum strings do in non-thermal pure quantum radiation (no information loss).(vi) New lower string bounds are given for the Kerr-Newman black hole angular momentum and charge, which are entirely different from the upper classical bounds. (vii) Semiclassical gravity states undergo a phase transition into quantum string states of the same system, these states are duals of each other in the precise sense of the usual classical-quantum (wave-particle) duality, which is universal irrespective of any symmetry or isommetry of the space-time and of the number or the kind of space-time dimensions.

description: This work presents a use case of building a data visualization interface for open access repositories. The case of analysis is the Brazilian Digital Library of Thesis and Dissertations (BDTD). R is a statistical tool very used among developers and programmers. One of its packages is called Shiny, that makes it easy to build interactive web apps straight from R. Through the app, the user can visualize data in a fast and customizable way. It could help them to keep track of metadata and usage statistics over the institutional repositories and can also be applied to discovering scientific information, such as bibliographic references and lists of specialists in certain research domain. These data visualization tools can stimulate others to create open repositories and join either national, regional or international repositories networks.

description: This thesis is concerned with the design of distributed algorithms for solving optimization problems. The particular scenario we consider is a network with P compute nodes, where each node p has exclusive access to a cost function fp. We design algorithms in which all the nodes cooperate to find the minimum of the sum of all the cost functions, f1 + · · · + fP . Several problems in signal processing, control, and machine learning can be posed as such optimization problems. Given that communication is often the most energy-consuming operation in networks and, many times, also the slowest one, it is important to design distributed algorithms with low communication requirements, that is, communication-efficient algorithms. The two main contributions of this thesis are a classification scheme for distributed optimization problems of the kind explained above and a set of corresponding communication-efficient algorithms. The class of optimization problems we consider is quite general, since we allow that each function may depend on arbitrary components of the optimization variable, and not necessarily on all of them. In doing so, we go beyond the commonly used assumption in distributed optimization and create additional structure that can be explored to reduce the total number of communications. This structure is captured by our classification scheme, which identifies particular instances of the problem that are easier to solve. One example is the standard distributed optimization problem, in which all the functions depend on all the components of the variable. All our algorithms are distributed in the sense that no central node coordinates the network, all the communications occur exclusively between neighboring nodes, and the data associated with each node is always processed locally. We show several applications of our algorithms, including average consensus, support vector machines, network flows, and several distributed scenarios for compressed sensing. We also propose a new framework for distributed model predictive control, which can be solved with our algorithms. Through extensive numerical experiments, we show that our algorithms outperform prior distributed algorithms in terms of communication-efficiency, even some that were specifically designed for a particular application.

This is done by extending the methods of homological perturbation theory, originally based on the use of a single resolution, to the case of a biresolution.

description: Time series, as frequently the case in neuroscience, are rarely stationary, but often exhibit abrupt changes due to attractor transitions or bifurcations in the dynamical systems producing them. A plethora of methods for detecting such change points in time series statistics have been developed over the years, in addition to test criteria to evaluate their significance. Issues to consider when developing change point analysis methods include computational demands, difficulties arising from either limited amount of data or a large number of covariates, and arriving at statistical tests with sufficient power to detect as many changes as contained in potentially high-dimensional time series. Here, a general method called Paired Adaptive Regressors for Cumulative Sum is developed for detecting multiple change points in the mean of multivariate time series. The method's advantages over alternative approaches are demonstrated through a series of simulation experiments. This is followed by a real data application to neural recordings from rat medial prefrontal cortex during learning. Finally, the method's flexibility to incorporate useful features from state-of-the-art change point detection techniques is discussed, along with potential drawbacks and suggestions to remedy them.

description: We investigate the electronic structure and several properties, and topological character, of the cubic time-reversal invariant intermetallic compounds PbPd$_3$ and SnPd$_3$ using density functional theory based methods. These compounds have a dispersionless band along the $Γ-X$ line, forming the top of the Pd $4d$ bands and lying within a few meV of the Fermi level $E_F$. Effects of the flat band on transport and optical properties have been inspected by varying the doping concentration treated with the virtual crystal approximation for substitution on the Pb site. In the absence of spin-orbit coupling (SOC), we find triple nodal points and three-dimensional nodal loops, which are known to lead to surface bands and drumhead states, respectively, which we discuss for PbPd$_3$. SOC removes degeneracy in most of the zone, providing a topological index $Z_2$=1 on the $k_z=0$ plane that indicates a topological character on that plane. The isovalent and isostructural compound SnPd$_3$ shows only minor differences in its electronic structures, so it is expected to display similar electronic, transport, and topological properties.

description: Warum haben wir ausgerechnet einen Roboter für unseren Titel ausgesucht, der starke Ähnlichkeit hat mit Robbi aus „Robbi, Tobbi und das Fliewatüüt“. Ein Roboter aus den 80ern als Sinnbild für die Zukunft der Arbeit? Nicht ganz. Er steht vielmehr für die Anfänge der Automatisierung, mit der das Ende der Arbeit prophezeit wurde. Heute schaut sein moderner, agiler Nachfolger keck ums Eck. Der „Robbi“ von heute ist hervorgegangen aus einer ständigen technologischen Entwicklung, die unsere Arbeitswelt in erheblichem Maße verändert hat und noch verändern wird. Wie Sie sehen werden, war „Robbi“ sehr wandlungsfähig. Doch was bedeutet das für uns? Wie könnte sie aussehen, die Zukunft der Arbeit? Und was verändert sich dadurch für jeden Einzelnen von uns? Diese Fragen haben wir Professorinnen und Professoren aller Fakultäten gestellt. Sie beschäftigen sich in ihrer Forschung mit digitalen Arbeitsmodellen und zukunftsfähigen Bildungskonzepten, mit Krankenhäusern der Zukunft und Künstlicher Intelligenz. Vieles unterscheidet sich, doch vieles ist auch gleich: Es geht um Vertrauen. Was bedeutet die zunehmende Digitalisierung für unsere Arbeitskultur? Es geht um Verantwortung, uns selbst und anderen gegenüber. Es geht um Vielfalt. Wer sind sie, die Arbeitskräfte von morgen? Es geht um Vernetzung, denn die ist in einer digitalen Welt allgegenwärtig. Für uns als Hochschule ist die „Zukunft der Arbeit“ ein besonders wichtiges Thema, denn unsere Studierenden heute werden sich morgen in dieser neuen Arbeitswelt bewegen und sie gestalten. Welche Kompetenzen müssen wir Ihnen vermitteln? Das ist eine Frage, die wir uns immer wieder neu stellen.

description: The standard treatment of human visceral leishmaniasis involves the use of pentavalent antimony (Sbv). Its mechanism of action is unknown because of the limited information available about intracellular antimony metabolism and about the genes that regulate these processes. Herein, flow injection-inductively coupled plasma mass spectrometry (ICP-MS), flow injection hydride generation ICP-MS, and ion chromatography ICP-MS were used to measure antimony accumulation and intracellular metabolism in the human protozoan parasite Leishmania donovani. Amastigotes (the intracellular form) and promastigotes (the extracellular form) accumulate Sbv and Sb III via separate transport systems. Stage-specific intracellular Sbv reducing activity was apparent in amastigotes, which reduced the negligibly toxic Sbv to highly toxic SbIII. This amastigote-specific reducing activity was deficient in the Pentostam-resistant mutant L. donovani Ld1S.20. These data indicate that parasite susceptibility to Sbv correlates with its level of Sbv reducing activity. Also, in promastigotes of both wild-type L. donovani and the Pentostam-resistant mutant L. donovani Ld1S.20, Sbv inhibited the toxicity of SbIII but not of AsIII. Both Sbv and SbIII were toxic to wild-type amastigotes. However, as observed in promastigotes, in mutant amastigotes Sbv inhibits Sb III but not AsIII activity. Anion exchange chromatography showed that intracellular antimony metabolism occurred in both promastigotes and amastigotes. These data demonstrate that the interaction between the two antimony oxidation states occurs intracellularly, within the parasite. The results also indicate that Sbv anti-leishmanial activity is dependent on its reduction to SbIII. The mechanism of this novel intracellular Sbv reduction has yet to be identified, and it may or may not be enzymatic. This is the first description of intracellular Sb v reducing activity in Leishmania as well as in any prokaryotic or eukaryotic cell.

description: Cosmic Microwave Background (CMB) anisotropies that result from quantum fluctuations during inflation are explored and the impact of their ``cosmic variance'' on the ability to use existing data to probe inflationary models is studied. We calculate the rms temperature fluctuation, and its cosmic variance, for a number of experiments and for models with primordial power spectra which range from $n={1\over 2}$ to $1$. We find: (1) cosmic variance obscures the information which can be extracted, so a comparison of the rms temperature fluctuation on small scales with the COBE result can fix $n$ to only $\approx\pm 0.2$ at best; (2) measurements of the rms fluctuation on $1^{\circ}$ scales may not allow one to unambiguously infer the tensor contribution to the COBE anisotropy; (3) comparison of this contribution with the predictions of inflation are ambiguous if the quadrupole anisotropy alone is utilized. We discuss means for minimizing the uncertainty due to cosmic variance in comparisons between experiments.

Differential cross-sections and escape plots for low energy $SU(2)$ BPS magnetic monopole dynamics

description: We compute the low-energy classical differential scattering cross-section for BPS $SU(2)$ magnetic monopoles using the geodesic approximation to the actual dynamics and 16K parallel processors on a CM2. Numerical experiments suggest that the quantum BPS magnetic monopole differential cross-section is well-approximated by the classical BPS magnetic monopole differential cross-section. In particular, the expected quantum interference effects for bosons at scattering angle $θ=π/2$ (CoM frame) are contradicted numerically. We argue that this is due to the topology of the classical configuration space for these solitons. We also study the scattering and bounded classical motions of BPS dyons and their global structure in phase space by constructing `escape plots'. The escape plots contain a surprising amount of structure, and suggest that the classical dynamics of two BPS $SU(2)$ magnetic monopoles is chaotic and that there are closed and bounded two dyon motions with isolated energies.
