description: In this paper, we study the effect of different word-level preprocessing decisions for Arabic on SMT quality. Our results show that given large amounts of training data, splitting off only proclitics performs best. However, for small amounts of training data, it is best to apply English-like tokenization using part-of-speech tags, and sophisticated morphological analysis and disambiguation. Moreover, choosing the appropriate preprocessing produces a significant increase in BLEU score if there is a change in genre between training and test data.
Investigation of Ca-doped Yttrium Iron Garnet for Solid Oxide Fuel Cells
Creators: name: Zhang, Zheyu
Publisher: name: Science
Year: 2020
Subjects: subject: Materials Science

description: Solid oxide fuel cells (SOFCs) are among the next-generation electrochemical energy conversion devices with higher energy efficiency. A major drawback hindering the mass commercialization of SOFCs is the slow oxygen reduction reaction kinetics at the cathode when the operating temperature is lowered from a high temperature (~1000 °C) to an intermediate temperature (500–750 °C). While many perovskite materials have been considered for use in novel SOFC cathodes, there remains a number of issues, such as large thermal expansion coefficient of Ba0.5Sr0.5Co0.8Fe0.2O3-δ due to the presence of Co and chemical instability under humidity and CO2- containing atmosphere of various perovskites. Therefore, the search, characterization and optimization of new cathode materials is of vital importance to the development of SOFCs. In this work, garnet-type Y3-xCaxFe5O12-δ was investigated as a promising candidate for a novel SOFC cathode. Structural variations from Ca-substitution in the parent phase Y3Fe5O12 was studied using powder X-ray diffraction. Different charge compensation mechanisms because of aliovalent doping of Ca were studied and validated through iodometric titration and X-ray absorption spectroscopy. It was suggested that formation of oxide ion vacancy and electron-hole co-exist in Ca-doped garnet samples. The maximum electrical conductivity was found in the x = 0.1 garnet composition, whose ionic transport number was revealed to be about 1.82×10-5 at 750 °C. Symmetrical cells with garnet and La0.8Sr0.2Ga0.8Mg0.2O3-δ composite electrode were fabricated and evaluated for their electrochemical properties at 600–900 °C in air and at 750 °C in various oxygen partial pressures. At 750 °C, the lowest area-specific resistance in air was obtained by x = 0.3 garnet composition, with dissociation and partial reduction of adsorbed oxygen identified as rate-limiting steps.

description: We report on machine learning experiments to distinguish deceptive from non-deceptive speech in the Columbia-SRI-Colorado (CSC) corpus. Specifically, we propose a system combination approach using different models and features for deception detection. Scores from an SVM system based on prosodic/lexical features are combined with scores from a Gaussian mixture model system based on acoustic features, resulting in improved accuracy over the individual systems. Finally, we compare results from the prosodic-only SVM system using features derived either from recognized words or from human transcriptions.
Adiabatic continuity and broken symmetry in many-electron systems: a variational perspective

description: Variational wave functions are very useful for describing the panoply of ground states found in interacting many-electron systems. Some particular trial states are "adiabatically" linked to a reference state, from which they borrow the essential properties. A prominent example is the Gutzwiller ansatz, where one starts with the filled Fermi sea. A simple soluble example, the anisotropic XY chain, illustrates the adiabatic continuity of this class of wave functions. To describe symmetry breaking, one has to modify the reference state accordingly. Alternatively, a quantum phase transition can be described by a pair of variational wave functions, starting at weak and strong coupling, respectively.
A functional framework for evaluating visualization applications, with a focus on financial analysis problems

Publisher: name: University of British Columbia
Year: 2012

description: The aim of this project is to bridge the gap between Visual Analytics (VA) research and application development and deployment in imperfect conditions, and to address some of the multi-layered and often vaguely-defined problems in industry. The first goal of this project is to create a functional framework to evaluate the suitability of VA applications for various investment analysis problems. This framework can guide the development process of such applications and address several secondary challenges to deploying VA solutions in financial organizations, such as problems in file formats and information management. These secondary challenges are relevant not only to VA, but also to the deployment of other computer-aided analytic processes. The construction of the framework began with an extensive literature survey on common investment analysis problems, VA techniques, sense making and intelligence analysis theories, and previous attempts by other VA researchers in creating classifications of VA techniques. It was then developed to evaluate the suitability of several mature VA products with regard to common investment analysis problems. This evaluation framework was next applied in a case study in a Fixed-income investment company, with the supervision of Dr. Victoria Lemieux and domain-expertise advise from two Masters of Finance students. This study involved systematically investigating the analytic process of the firm and isolating areas that could be improved with VA. These detailed problem definitions were then mapped to VA techniques to find the optimal visualizations and interactions for the problem. The case study also involved implementing a solution for the company by building upon an open-source toolkit that was evaluated with the framework. Preliminary results suggested that the prototype “significantly improves the speed with which we (analysts) see the impact of movements of the yield curve on client’s surpluses/deficits…” The field-testing analyst also did not find any aspect of the interface to be difficult to learn or unpleasant to use.

description: The standard interference functions introduced by Yates have been very influential on the analysis and design of distributed power control laws. While powerful and versatile, the framework has some drawbacks: the existence of fixed-points has to be established separately, and no guarantees are given on the rate of convergence of the iterates. This paper introduces contractive interference functions, a slight reformulation of the standard interference functions that guarantees the existence and uniqueness of fixed-points along with linear convergence of iterates. We show that many power control laws from the literature are contractive and derive, sometimes for the first time, analytical convergence rate estimates for these algorithms. We also prove that contractive interference functions converge when executed totally asynchronously and, under the assumption that the communication delay is bounded, derive an explicit bound on the convergence time penalty due to increased delay. Finally, we demonstrate that although standard interference functions are, in general, not contractive, they are all para-contractions with respect to a certain metric. Similar results for two-sided scalable interference functions are also derived.

description: Quality Rating Improvement Systems (QRISs) commonly offer on-site technical assistance (TA) and coaching to help early care and education settings achieve quality improvements and a higher QRIS rating. In surveys of administrators overseeing statewide QRISs, almost all states reported the use of on-site TA and coaching in both center-based and home-based settings. Coaching is also a key component of several pilot and local QRISs. While recently proposed definitions of technical assistance and coaching help distinguish these forms of quality assistance from other types of professional development it will be important to learn more about how on-site assistance is delivered and supported in QRISs. This report presents findings from an interview study with TA providers in 17 states that have statewide QRISs. The aims of the study are: (1) to learn about features of on-site quality assistance so that a key strategy used by QRISs to improve quality is better understood; and (2) to examine approaches used by TA providers in light of current research on early learning and quality improvement in order to consider the potential of on-site assistance, as it is currently being delivered, to improve quality.

description: The paper explores the potentials and political feasibility of intergovernmental measures aiming at the protection of democracy and the rule of law in the European Union. It pays special attention to the potential application of Article 259 of the Treaty on the Functioning of the European Union (TFEU) that allows autocratizing Member States to be referred to the Court of Justice of the European Union (CJEU) by another Member State (‘biting intergovernmentalism’). Using an explorative, theory building approach based on the analysis of semi-structured stakeholder interviews, the paper concludes that ‘biting intergovernmentalism’ is subject to a collective action trap that withholds even the most committed ‘friends of rule of law’ countries from its application. According to the stakeholders’ ruling perception of ‘biting intergovernmentalism’, Article 259 TFEU provides a secondary, complementary legal venue for Member States to protect the common good of EU law and uphold European values if the European Commission is unable to live up to its role as guardian of the treaties. Hence, due its perceived complementary role, the legal potentials enshrined in Article 259 TFEU cannot be fully realized under the given political conditions. Nevertheless, ‘biting intergovernmentalism’ can serve as a leverage over the European Commission through which Member States can influence the Commission’s litigation strategy in direction of a more committed protection of democracy and the rule of law in the EU. Based on the case studies of The Netherlands, Denmark, Belgium, Finland, Germany, and Sweden, the paper investigates the main variables that determine the approach of ‘friends of rule of law’ countries to ‘biting intergovernmentalism’ and argues that the protection of democracy and the rule of law by Member States is primarily a domestic bottom-up political process highly dependent from the existence and level of agenda setting and political entrepreneurship at the domestic stage.

description: We use a corpus of spontaneous interview speech to investigate the relationship between the distributional and prosodic characteristics of silent and filled pauses and the intent of an interviewee to deceive an interviewer. Our data suggest that the use of pauses correlates more with truthful than with deceptive speech, and that prosodic features extracted from filled pauses themselves as well as features describing contextual prosodic information in the vicinity of filled pauses may facilitate the detection of deceit in speech.
Automatic Summarization of Conversational Multi-Party Speech

description: Document summarization has proven to be a desirable component in many information management systems, complementing core information retrieval and browsing functionalities. The use of document summarization techniques is especially important with speech documents such as meeting transcriptions, since they are particularly difficult to navigate. As opposed to their written counterparts, spoken documents lack structural elements like title, headers, and paragraphs that can ease the task of the information seeker. Document summarization can reduce the overhead of navigating large collections of speech data. For example, summarization techniques can be used to extract or highlight relevant passages in a full transcription. Alternatively, similar techniques might be used to generate short text substitutes, or abstracts, that capture the “aboutness” of the meeting, while discarding disfluencies and other unimportant elements.
Atmospheric dispersion effects in weak lensing measurements

description: The wavelength dependence of atmospheric refraction causes elongation of finite-bandwidth images along the elevation vector, which produces spurious signals in weak gravitational lensing shear measurements unless this atmospheric dispersion is calibrated and removed to high precision. Because astrometric solutions and PSF characteristics are typically calibrated from stellar images, differences between the reference stars' spectra and the galaxies' spectra will leave residual errors in both the astrometric positions (dr) and in the second moment (width) of the wavelength-averaged PSF (dv) for galaxies.We estimate the level of dv that will induce spurious weak lensing signals in PSF-corrected galaxy shapes that exceed the statistical errors of the DES and the LSST cosmic-shear experiments. We also estimate the dr signals that will produce unacceptable spurious distortions after stacking of exposures taken at different airmasses and hour angles. We also calculate the errors in the griz bands, and find that dispersion systematics, uncorrected, are up to 6 and 2 times larger in g and r bands,respectively, than the requirements for the DES error budget, but can be safely ignored in i and z bands. For the LSST requirements, the factors are about 30, 10, and 3 in g, r, and i bands,respectively. We find that a simple correction linear in galaxy color is accurate enough to reduce dispersion shear systematics to insignificant levels in the r band for DES and i band for LSST,but still as much as 5 times than the requirements for LSST r-band observations. More complex corrections will likely be able to reduce the systematic cosmic-shear errors below statistical errors for LSST r band. But g-band effects remain large enough that it seems likely that induced systematics will dominate the statistical errors of both surveys, and cosmic-shear measurements should rely on the redder bands.

description: We investigate the optical properties of layered structures with graphene at the interface for arbitrary linear polarization at finite temperature including full retardation by working in the Weyl gauge. As a special case, we obtain the full response and the related dielectric function of a layered structure with two interfaces. We apply our results to discuss the longitudinal plasmon spectrum of several single and double layer devices such as systems with finite and zero electronic densities. We further show that a nonhomogeneous dielectric background can shift the relative weight of the in-phase and out-of-phase mode and discuss how the plasmonic mode of the upper layer can be tuned into an acoustic mode with specific sound velocity.

description: We consider the dynamics of a tagged particle in an infinite particle environment moving according to a stochastic gradient dynamics. For singular interaction potentials this tagged particle dynamics was constructed first in [FG11], using closures of pre-Dirichlet forms which were already proposed in [GP87] and [Osa98]. The environment dynamics and the coupled dynamics of the tagged particle and the environment were constructed separately. Here we continue the analysis of these processes: Proving an essential m-dissipativity result for the generator of the coupled dynamics from [FG11], we show that this dynamics does not only contain the environment dynamics (as one component), but is, given the latter, the only possible choice for being the coupled process. Moreover, we identify the uniform motion of the environment as the reversed motion of the tagged particle. (Since the dynamics are constructed as martingale solutions on configuration space, this is not immediate.) Furthermore, we prove ergodicity of the environment dynamics, whenever the underlying reference measure is a pure phase of the system. Finally, we show that these considerations are sufficient to apply [DMFGW89] for proving an invariance principle for the tagged particle process. We remark that such an invariance principle was studied before in [GP87] for smooth potentials, and shown by abstract Dirichlet form methods in [Osa98] for singular potentials. Our results apply for a general class of Ruelle measures corresponding to potentials possibly having infinite range, a non-integrable singularity at 0 and a nontrivial negative part, and fulfill merely a weak differentiability condition on $\mathbb R^d\setminus\{0\}$.

description: We examine numerically the post-merger regime of two Schwarzschild black holes in non head-on collision. Our treatment is made in the realm of non-axisymmetric Robinson-Trautman spacetimes which are appropriate for the description of the system. Characteristic initial data for the system are constructed and the Robinson-Trautman equation is integrated using a numerical code based on the Galerkin spectral method. The collision is planar, restricted to the plane determined by the directions of the two initial colliding black holes, with the net momentum fluxes of gravitational waves confined to this plane. We evaluate the efficiency of mass-energy extraction, the total energy and momentum carried out by gravitational waves and the momentum distribution of the remnant black hole. Our analysis is based on the Bondi-Sachs four momentum conservation laws. Head-on collisions and orthogonal collisions constitute, respectively, upper and lower bounds to the power emission and to the efficiency of mass-energy extraction by gravitational waves. The momentum extraction and the pattern of the momentum fluxes, as a function of the incidence angle, are examined. The momentum extraction characterizes a regime of strong deceleration of the system. The angular pattern of gravitational wave signals is also examined. They are typically bremsstrahlung for early times emission. Gravitational waves are also emitted outside the plane of collision but this component has a zero net momentum flux. The relation between the incidence angle of collision and the exit angle of the remnant closely approximates a relation for inelastic collisions of classical particles in Newtonian dynamics.

description: In den letzten Jahren hat sich der Bedarf an Biopharmazeutika stark erhöht. Dabei sind etwa 70 % der Biopharmazeutika N-glykosyliert und weisen Mikroheterogenitäten auf. Um die Funktion von N‐Glykanen sowohl bei gesunder Physiologie als auch in Krankheitszuständen untersuchen zu können, werden homogene N‐Glykane benötigt. Eine Möglichkeit, diese kostengünstig herzustellen, ist die in vitro‐Synthese. Eine Herausforderung stellt dabei die Bereitstellung der Enzyme und Substrate dar. Dafür müssen rekombinante Expressionssysteme etabliert und Glykan‐Donatoren als aktivierte Nukleotid‐Zucker bereitgestellt werden. Im Rahmen dieser Arbeit gelang es, das Glykokonjugat Phytanyl‐PP‐(GlcNAc)2Man1 unter Verwendung einer rekombinanten, gereinigten β1,4‐Mannosyltransferase enzymatisch in vitro im präparativen Maßstab herzustellen. Zudem wurden Enzyme gereinigt, die das kostenintensive Donorsubstrat GDP‐Mannose aus günstigen Ausgangsstoffen synthetisieren und anfallende Nebenprodukte regenerieren.
description: In recent years the demand for biopharmaceuticals steadily increased. 70 % of the biopharmaceuticals are N-glycosylated and show microheterogeneities. To investigate the function of N‐glycans for both normal and pathogenic state, homogeneous N‐glycans are needed. One cost-effective opportunity to provide these glycans is the in vitro‐synthesis. The provision of the necessary enzymes and substrates is a major challenge. Therefor, recombinant expression systems need to be established and activated sugar nucleotides as glycan donors should be provided. In summary, in the course of this study the glycoconjugate Phytanyl‐PP‐(GlcNAc)2Man1 was provided by using a recombinant, purified β1,4‐Mannosyltransferase enzymatically in vitro in a preparative scale. Further investigations included the development of a synthesis and regeneration system for the expensive donor substrate GDP-Mannose with cost-efficiently implemented starting materials applying suitable, purified enzymes.

description: We present the first proper motion measurements for the galaxy M31. We obtained new V-band imaging data with the HST ACS/WFC and WFC3/UVIS of a spheroid field near the minor axis, an outer disk field along the major axis, and a field on the Giant Southern Stream. The data provide 5-7 year time baselines with respect to pre-existing deep first-epoch observations. We measure the positions of thousands of M31 stars and hundreds of compact background galaxies in each field. High accuracy and robustness is achieved by building and fitting a unique template for each individual object. The average proper motion for each field is obtained from the average motion of the M31 stars between the epochs with respect to the background galaxies. For the three fields, the observed proper motions (mu_W,mu_N) are (-0.0458, -0.0376), (-0.0533, -0.0104), and (-0.0179,-0.0357) mas/yr, respectively. The ability to average over large numbers of objects and over the three fields yields a final accuracy of 0.012 mas/yr. The robustness of the proper-motion measurements and uncertainties are supported by the fact that data from different instruments, taken at different times and with different telescope orientations, as well as measurements of different fields, all yield statistically consistent results. Papers II and III explore the implications for our understanding of the history, future, and mass of the Local Group. (Abridged)

description: We present a data dependent generalization bound for a large class of regularized algorithms which implement structured sparsity constraints. The bound can be applied to standard squared-norm regularization, the Lasso, the group Lasso, some versions of the group Lasso with overlapping groups, multiple kernel learning and other regularization schemes. In all these cases competitive results are obtained. A novel feature of our bound is that it can be applied in an infinite dimensional setting such as the Lasso in a separable Hilbert space or multiple kernel learning with a countable number of kernels.

description: Cross-linked and flexible poly(vinyl acetone ketal) (PV-A-K) films have been prepared as a result of ketalization reaction and monolith formation of poly(vinyl alcohol) (PVA), which has the feature of forming films quickly and is frequently used in biological fields. In this novel method, flexible PV-A-K films have been produced simply and in a short time accompanied by monolith formation without any catalyst in acetone. The effect of acetone ratio on the physical properties (i.e., swelling and mechanical properties) of such formations has been investigated to reveal significant influences of it. In addition, zinc oxide (ZnO) nanoparticles synthesized via the solvothermal method have been doped into PV-A-K films during film preparation. The prepared PV-A-K and ZnO doped PV-A-K films have been characterized with SEM, XRD, and FT-IR. Their mechanical properties have been investigated with a universal mechanical test machine. The acetone ratio is quite effective both on the porosity and stress/strain properties of the films. Antibacterial activities of the films are evaluated against four different strains (E. coli, S. aureus, P. aeruginosa, and E. faecalis) via the disk diffusion method. The films are selectively effective against S. aureus. These highly flexible and elastic films have great potential for biomedical applications, wound dressing, and antibacterial surface preparation.

description: Although finding numerically the quasinormal modes of a nonrotating black hole is a well-studied question, the physics of the problem is often hidden behind complicated numerical procedures aimed at avoiding the direct solution of the spectral system in this case. In this article, we use the exact analytical solutions of the Regge-Wheeler equation and the Teukolsky radial equation, written in terms of confluent Heun functions. In both cases, we obtain the quasinormal modes numerically from spectral condition written in terms of the Heun functions. The frequencies are compared with ones already published by Andersson and other authors. A new method of studying the branch cuts in the solutions is presented -- the epsilon-method. In particular, we prove that the mode $n=8$ is not algebraically special and find its value with more than 6 firm figures of precision for the first time. The stability of that mode is explored using the $ε$ method, and the results show that this new method provides a natural way of studying the behavior of the modes around the branch cut points.

description: The dewetting dynamics of an ultrathin film is studied in the presence of evaporation - or reaction - of adatoms on the substrate. KMC simulations are in good agreement with an analytical model with diffusion, rim facetting, and substrate sublimation. As sublimation is increased, we find a transition from the usual dewetting regime where the front slows down with time, to a sublimation-controlled regime where the front velocity is approximately constant. The rim width exhibits an unexpected non-monotonous behavior, with a maximum in time.

Impacts on the I/O performance of the virtual disk in Xen

description: Storage systems are complicated, especially after the virtualization technology has been introduced. As is a key metric, the I/O throughput of the storage in the virtual machine environment is remarkably lower than that in the non-virtualized environment. This disparity should be alleviated because of the growing popularity of virtual machines. In this paper, four factors, which affect the I/O throughput of the generic Linux storage subsystem and further degrade virtualization on this storage subsystem, are testified by quantitative approaches, leading to the effective solutions of improving the I/O throughput. The improvements are verified by experiments; however, the overhead of virtualization is inevitable. Therefore, a further way to offset the overhead is also given in this thesis.

description: In the event of a pandemic flu outbreak, closing schools would be one of the most likely non pharmaceutical interventions (NPI) considered to contain the outbreak, consistent with social distancing theories (Hodge 2006, Germann 2006). Children in preschool and school-age groups are frequently observed to amplify transmission of many forms of flu (Bell 2006, Germann 2006), and are often the first mechanism for introducing transmission into the home (Cedron 2006). Despite the propensity of influenza epidemics to be amplified in primary schools, data on the effectiveness of school closures are limited (Bell 2006), especially in recent years, and the impact of school closures on illness rates appears to be mixed (Ingelsby 2006).

description: We show that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma profile. Strong plasma heating and density steepening produced by an intense laser pulse near the critical density can launch such shocks that propagate in the extended plasma at high velocities. The generation of a monoenergetic ion beam is possible due to the small and constant sheath electric field associated with the slowly decreasing density profile. The conditions for the acceleration of high-quality, energetic ion beams are identified through theory and multidimensional particle-in-cell simulations. The scaling of the ion energy with laser intensity shows that it is possible to generate $\sim 200$ MeV proton beams with state-of-the-art 100 TW class laser systems.

description: The emergency communication systems are undergoing a transition from the PSTN-based legacy system to an IP-based next generation system. In the next generation system, GPS accurately provides a user's location when the user makes an emergency call outdoors using a mobile phone. Indoor positioning, however, presents a challenge because GPS does not generally work indoors. Moreover, unlike outdoors, vertical accuracy is critical indoors because an error of few meters will send emergency responders to a different floor in a building. This paper presents an indoor positioning system which focuses on improving the accuracy of vertical location. We aim to provide floor-level accuracy with minimal infrastructure support. Our approach is to use multiple sensors available in today's smartphones to trace users' vertical movements inside buildings. We make three contributions. First, we present the elevator module for tracking a user's movement in elevators. The elevator module addresses three core challenges that make it difficult to accurately derive displacement from acceleration. Second, we present the stairway module which determines the number of floors a user has traveled on foot. Unlike previous systems that track users' foot steps, our stairway module uses a novel landing counting technique. Third, we present a hybrid architecture that combines the sensor-based components with minimal and practical infrastructure. The infrastructure provides initial anchor and periodic corrections of a user's vertical location indoors. The architecture strikes the right balance between the accuracy of location and the feasibility of deployment for the purpose of emergency communication.
