description: Online knowledge repositories typically rely on their users or dedicated editors to evaluate the reliability of their content. These evaluations can be viewed as noisy measurements of both information reliability and information source trustworthiness. Can we leverage these noisy evaluations, often biased, to distill a robust, unbiased and interpretable measure of both notions? In this paper, we argue that the temporal traces left by these noisy evaluations give cues on the reliability of the information and the trustworthiness of the sources. Then, we propose a temporal point process modeling framework that links these temporal traces to robust, unbiased and interpretable notions of information reliability and source trustworthiness. Furthermore, we develop an efficient convex optimization procedure to learn the parameters of the model from historical traces. Experiments on real-world data gathered from Wikipedia and Stack Overflow show that our modeling framework accurately predicts evaluation events, provides an interpretable measure of information reliability and source trustworthiness, and yields interesting insights about real-world events.

description: We present a novel unsupervised approach for multilingual sentiment analysis driven by compositional syntax-based rules. On the one hand, we exploit some of the main advantages of unsupervised algorithms: (1) the interpretability of their output, in contrast with most supervised models, which behave as a black box and (2) their robustness across different corpora and domains. On the other hand, by introducing the concept of compositional operations and exploiting syntactic information in the form of universal dependencies, we tackle one of their main drawbacks: their rigidity on data that are structured differently depending on the language concerned. Experiments show an improvement both over existing unsupervised methods, and over state-of-the-art supervised models when evaluating outside their corpus of origin. Experiments also show how the same compositional operations can be shared across languages. The system is available at http://www.grupolys.org/software/UUUSA/

description: In this work we give, for the first time, the full relativistic Lagrangian density describing the motion of induced electric dipoles in the electric fields which induce the dipole, and the magnetic fields which generate the HMW topological phase. We then use this relativistic Lagrangian density to derive the complete set of conditions for producing topological phases with induced dipoles. We also give the relativistic Lagrangian density describing the motion of induced magnetic dipoles in the magnetic fields which induce the dipole, and the electric fields which generate the AC topological phase, and derive the conditions for this AC phase to be topological. These conditions have been incompletely discussed in previous studies. We note that, in both the AC and HMW cases, the topological phases are generated by the cross product of electric and magnetic fields in the form $\bm{B} \times \bm{E}$ which reinforces the dual nature of these two topological phases.

description: We consider f(R,T) modified theory of gravity, in which the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar and the trace of the energy-momentum tensor of the matter, in order to investigate the dark-matter effects on the galaxy scale. We obtain the metric components for a spherically symmetric and static spacetime in the vicinity of general relativity solutions. However, we concentrate on a specific model of the theory where the matter is minimally coupled to the geometry, and derive the metric components in the galactic halo. Then, we fix the components by the rotational velocities of the galaxies for the model, and show that the mass corresponding to the interaction term (which appears in the Einstein modified field equation) leads to a flat rotation curve in the halo of galaxies. In addition, for the proposed model, the light-deflection angle has been derived and drawn using some observed data.

description: This paper proposes a new design for the compressive split Hopkinson bar that makes use of the intense pressure created in a transient magnetic field formed by the passage of a pulse of electric current through a series of coils. The proposed technology enables to characterize the behaviour of materials under high strain-rates with a small acceleration path length of the striker bar and, because propulsion is purely electromagnetic, the overall performance can be easily controlled and nearly infinitely adjustable. The presentation is focused on the design and fabrication of the mechanical, electrical and electromagnetic components of the new compressive split Hopkinson bar and includes results from two different testing applications to demonstrate the validity of the proposed concept.
Speciation in the Derrida-Higgs model with finite genomes and spatial populations

Year: 2016
Subjects: subject: Populations and Evolution (q-bio.PE)

description: The speciation model proposed by Derrida and Higgs demonstrated that a sexually reproducing population can split into different species in the absence of natural selection or any type of geographic isolation, provided that mating is assortative and the number of genes involved in the process is infinite. Here we revisit this model and simulate it for finite genomes, focusing on the question of how many genes it actually takes to trigger neutral sympatric speciation. We find that, for typical parameters used in the original model, it takes of the order of $10^5$ genes. We compare the results with a similar spatially explicit model where about 100 genes suffice for speciation. We show that when the number of genes is small the species that emerge are strongly segregated in space. For larger number of genes, on the other hand, the spatial structure of the population is less important and the species distribution overlap considerably.

description: Understanding if and how mutants reach fixation in populations is an important question in evolutionary biology. We study the impact of population growth has on the success of mutants. To systematically understand the effects of growth we decouple competition from reproduction; competition follows a birth--death process and is governed by an evolutionary game, while growth is determined by an externally controlled branching rate. In stochastic simulations we find non-monotonic behaviour of the fixation probability of mutants as the speed of growth is varied; the right amount of growth can lead to a higher success rate. These results are observed in both coordination and coexistence game scenarios, and we find that the 'one-third law' for coordination games can break down in the presence of growth. We also propose a simplified description in terms of stochastic differential equations to approximate the individual-based model.

description: Due to the high forming velocities during electromagnetic sheet metal forming processes, a high impact force acts between workpiece and die. Here, the die surface sustains high damages shown by high wear and galling of the workpiece on the die surface. To enhance the die lifetime, a novel coating concept based on the PVD (physical vapour deposition) process was developed. In doing so, the hardness and the toughness of the designed layers were varied and adjusted to the demands of AlMg-sheet forming process.

[Nat.~Phys., \textbf{11}, 1009 (2015)]. We observe a nonexponential collapse of the amplitude of the condensate oscillation followed by a partial revival. This behavior is identified as being due to beating between two eigenmodes of the system, corresponding to in-phase and out-of-phase oscillations of the condensed and noncondensed fractions of the gas. We perform finite temperature simulations of the system dynamics using the Zaremba-Nikuni-Griffin methodology [J.~Low Temp.~Phys., \textbf{116}, 277 (1999)], and find good agreement with the data, thus confirming the two mode description.

Characteristics of the mechanical behaviour of UFG a and a+ß titanium alloys in wide range of strain rates are discussed.
Continuous time limits of the Utterance Selection Model

description: In this paper, we derive new continuous time limits of the Utterance Selection Model (USM) for language change (Baxter et al., Phys. Rev. E {\bf 73}, 046118, 2006). This is motivated by the fact that the Fokker-Planck continuous time limit derived in the original version of the USM is only valid for a small range of parameters. We investigate the consequences of relaxing these constraints on parameters. Using the normal approximation of the multinomial approximation, we derive a new continuous time limit of the USM in the form of a weak-noise stochastic differential equation. We argue that this weak noise, not captured by the Kramers-Moyal expansion, can not be neglected. We then propose a coarse-graining procedure, which takes the form of a stochastic version of the \emph{heterogeneous mean field} approximation. This approximation groups the behaviour of nodes of same degree, reducing the complexity of the problem. With the help of this approximation, we study in detail two simple families of networks: the regular networks and the star-shaped networks. The analysis reveals and quantifies a finite size effect of the dynamics. If we increase the size of the network by keeping all the other parameters constant, we transition from a state where conventions emerge to a state when no convention emerges. Furthermore, we show that the degree of a node acts as a time scale. For heterogeneous networks such as star-shaped networks, the time scale difference can become very large leading to a noisier behaviour of highly connected nodes.

description: Despite the comprehensive understanding of the modeling and numerical simulation of electromagnetic metal forming that has recently been gained, the simulation of real forming situations is still a challenging task due to the large computational resources required. A bottleneck is the computation of the electromagnetic fields, since 100.000 up to several million unknowns are required to represent the geometry of a typical forming device. The purpose of this article is to present new techniques to speed up the simulation of electromagnetic metal forming with particular emphasis on the computation of the electromagnetic fields. An acceleration of the electromagnetic field computation is a significant step towards a virtual design of electromagnetic forming processes.

description: Ereignisdiskrete Modelle ermöglichen die Abbildung einer Vielzahl von Systemen. Eine wichtige Fragestellung bei der Betrachtung dieser Modelle ist die Bestimmung einer für einen bestimmten Zweck optimalen Modellvariante. In der Regel besteht die Aufgabe darin, eine optimale Konfiguration aus einer Menge möglicher Konfigurationen auszuwählen und anschließend umzusetzen. Die systematische Untersuchung, Bewertung und Modifikation solcher Modelle ist ein zeitintensiver Prozess, da zum einen die Menge der möglichen Konfigurationen in der Regel sehr groß und der Analyseaufwand sehr hoch ist. Daher werden Optimierungsverfahren und Suchheuristiken benötigt, um diesen Prozess zu unterstützen. In dieser Arbeit werden vor allem Kriging Metamodell basierte Verfahren auf ihre Einsetzbarkeit in diesem Gebiet untersucht und entsprechend der Anforderungen von ereignisdiskreten Modellen und deren Analysemethoden angepasst. Insbesondere werden hierarchische Kriging Metamodelle zur Reduktion der Rechenzeit und zur Erhöhung der Approximationsgenauigkeit entwickelt. Weitere Untersuchungen befassen sich mit der Kombination von Kriging Metamodell basierten Verfahren mit lokalen Suchheuristiken sowie "Ranking and Selection"-Verfahren.

Strongyloidiasis, scabies and impetigo - household clustering in a Northern Territory community
Creators: name: Howarth, Timothy
Publisher: name: Charles Darwin University
Year: 2016

description: Aim: To determine if there is household or geospatial clustering of strongyloidiasis, scabies and impetigo infections in a remote NT Aboriginal community. Methods: A population census was conducted at month 0 and 12 to determine prevalence of strongyloidiasis, scabies and impetigo. Household demographics and participant household lot numbers were obtained and GPS coordinates configured through Google Earth. Global and Local Morans statistic was used to identify the presence of household and geospatial clusters. Results: Nine-hundred and thirteen participants in 125 households were enrolled in month 0 and 981 in 128 households in month 12. Infection was identified in 68% of households at month 0 and 66% in month 12 (strongyloidiasis 60% (Month 0) and 45% (Month 12), scabies 23% and 35%, impetigo 29% and 41% respectively). Households with no infection had a significantly lower proportion of children aged <15 years (23%, 95%CI 17-29). Clusters were identified in eight households at month 0 and 10 at month 12 accounting for 23% and 33% of community infections respectively. Conclusion: GIS mapping identified household clusters of infection, indicating that household screening and treatment may be a more appropriate intervention than individual treatment to reduce transmission and burden of all three infections within communities.

Cosmological constraints from thermal Sunyaev Zeldovich power spectrum revisited

description: Thermal Sunyaev-Zeldovich (tSZ) power spectrum is one of the most sensitive methods to constrain cosmological parameters, scaling as the amplitude $σ_8^8$. It is determined by the integral over the halo mass function multiplied by the total pressure content of clusters, and further convolved by the cluster gas pressure profile. It has been shown that various feedback effects can change significantly the pressure profile, possibly even pushing the gas out to the virial radius and beyond, strongly affecting the tSZ power spectrum at high $l$. Energetics arguments and SZ-halo mass scaling relations suggest feedback is unlikely to significantly change the total pressure content, making low $l$ tSZ power spectrum more robust against feedback effects. Furthermore, the separation between the cosmic infrared background (CIB) and tSZ is more reliable at low $l$. Low $l$ modes are however probing very small volumes, giving rise to very large non-gaussian sampling variance errors. By computing the trispectrum contribution we identify $90

description: Since the electromagnetic forming (EMF) becomes more and more accepted within industrial manufacturing, the methods engineer has to deal with the choice of matching equipment as to perform the task of production in the best possible way. At the present time several manufacturers offer EMF-machines with different characteristics, whereby the machines consist of a pulse power generator and an exchangeable tool coil. The storable energy, the current capability and a high short circuit frequency enable the engineer to adapt tool coils for an optimised pressure course. In the following some aspects of how to dimension direct acting tool coil properties for the EM compression process will be considered. Basically the use of multi-turn coils is advantageous for a good matching. But in a lot of cases the use of a fieldshaper is necessary. It will be shown how the design of a tool coil system including a fieldshaper influences the pressure course. A special case is the application of EM compression in closed spaceframe structures for which a separable tool coil is required. A separable compression coil with non-welding contact elements will be presented.
Geometric embedding properties of Bestvina-Brady subgroups

description: We compute the relative divergence and the subgroup distortion of Bestvina-Brady subgroups. We also show that for each integer $n\geq 3$, there is a free subgroup of rank $n$ of some right-angled Artin group whose inclusion is not a quasi-isometric embedding. This result answers the question of Carr about the minimum rank $n$ such that some right-angled Artin group has a free subgroup of rank $n$ whose inclusion is not a quasi-isometric embedding. It is well-known that a right-angled Artin group $A_Γ$ is the fundamental group of a graph manifold whenever the defining graph $Γ$ is a tree. We show that the Bestvina-Brady subgroup $H_Γ$ in this case is a horizontal surface subgroup.

description: A promising proposal for resolving the cusp-core anomaly in the density profile of dwarf galaxies is to allow dark matter to interact with itself through a light mediator of mass much less than a GeV. The theoretical challenge is to have a complete renormalizable theory where this happens naturally even though dark matter itself may be of the electroweak scale, i.e. 100 GeV to 1 TeV. I propose here such a model, with just two neutral complex scalar singlets under a softly broken dark global U(1) symmetry.

Scaling Theory for the Frictionless Unjamming Transition

description: We develop a scaling theory of the unjamming transition of soft frictionless disks in two dimensions by defining local areas, which can be uniquely assigned to each contact. These serve to define local order parameters, whose distribution exhibits divergences as the unjamming transition is approached. We derive scaling forms for these divergences from a mean-field approach that treats the local areas as non interacting entities, and demonstrate that these results agree remarkably well with numerical simulations. We find that the asymptotic behaviour of the scaling functions arises from the geometrical structure of the packing while the overall scaling with the compression energy depends on the force law. We use the scaling forms of the distributions to determine the scaling of the total grain area $A_G$, and the total number of contacts $N_C$.

description: We study anomalous transport phenomena induced by phase-space Berry curvature. For that purpose we construct a kinetic theory in $2d$ phase space when all abelian Berry curvatures are nonzero. We derive anomalous currents by calculating the complete form of the Poisson brackets of phase space coordinates. Then we construct the low-energy effective theory to reproduce the anomalous currents obtained from the kinetic theory. Such an effective theory is given by the Chern-Simons theory in $1+2d$ dimensions. Some implications of the Chern-Simons theory are also discussed.

Unreinforced masonry

description: Concrete block masonry is a common building material used worldwide, including Canada. Reinforced masonry buildings, designed according to the requirements of recent building codes, may result in seismically safe structures. However, unreinforced masonry (URM) buildings designed and constructed prior to the development of modern seismic design codes are extremely vulnerable to seismic induced damage. Replacement of older seismically deficient buildings with new and seismically designed structures is economically not feasible in most cases. Therefore, seismic retrofitting of deficient buildings remains to be a viable seismic risk mitigation strategy. Masonry load bearing walls are the most important elements of such buildings, potentially serving as lateral force resisting systems. A seismic retrofit research program is currently underway at the University of Ottawa, consisting of experimental and analytical components for developing new seismic retrofit systems for unreinforced masonry walls. The research project presented in this thesis forms part of the same overall research program. The experimental component includes design, construction, retrofit and testing of large-scale load bearing masonry walls. Two approaches were developed as retrofit methodologies, both involving reinforcing the walls for strength and deformability. The first approach involves the use of ordinary deformed steel reinforcement as internally added reinforcement to attain reinforced masonry behaviour. The second approach involves the use of internally placed post-tensioning tendons to attain prestressed masonry behaviour. The analytical component of research consists of constructing a Finite Element computer model for nonlinear analysis of walls and conducting a parametric study to assess the significance of retrofit design parameters. The results have led to the development of a conceptual retrofit design framework for the new techniques developed, while utilizing the seismic provisions of the National Building Code of Canada and the relevant CSA material standards.

description: Die Auseinandersetzung mit der Morphologie des monumentalen Straßenraumes als einem eigenständigen architektonischen Thema stellt vor dem Hintergrund unterschiedlicher städtebaulicher Leitbilder eine wesentliche Konstante von Architektur und Städtebau in der ersten Hälfte des 20. Jahrhunderts dar. Im Hinblick auf seine Gestaltung, aber auch im Zusammenhang mit der Organisation der gesamten Stadt kommt dem monumentalen Straßenraum eine ganz besondere Rolle zu. Im 20. Jahrhundert ändern sich die Vorstellungen davon, was verehrungswürdig, erinnerungswert oder verherrlichungswert sei. Dies spiegelt sich auch in neuen Vorstellungen von städtischem Raum und städtischer Architektur wider. Die unterschiedlichen Ansprüche an Monumentalität zwischen politischen Idealen, ökonomischen Kräften, sozialen Verhältnissen und demokratischen Gleichheitsidealen haben einen deutlichen Einfluss auf die gestalterischen Mittel zur Erzeugung einer monumentalen Wirkung. Theoretische Verwandtschaften und Kontinuitäten manifestieren sich im Gebauten und Entworfenen gleichermaßen und zeigen sich im Bereich der Großstadt wohl am eindrücklichsten im öffentlichen Raum des monumentalen Straßenraums. Die Zusammenstellung der analysierten monumentalen Straßenräume und die Auseinandersetzung mit den schriftlichen Quellen machen deutlich, dass es sich bei den monumentalen Straßenräumen bis auf wenige Ausnahmen um multifunktionale öffentliche Räume handelt. Dabei wird deutlich, dass trotz der funktionalen Vielfalt die monumentalen Straßenräume auf dem Prinzip des Korridorstraßenraumes beruhen, in ähnlichen Dimensionen angelegt werden und deren raumbegrenzenden Wandungen nach immer wieder kehrenden Merkmalen gestaltet sind. Die große Anzahl monumentaler Straßenräume in Europa in der ersten Hälfte des 20. Jahrhunderts belegt nicht nur deren große geographische Verbreitung, sondern auch eine kontinuierliche Verwendung dieses für die Großstadt so bedeutenden Elements. Trotz der oftmals propagierten Abschaffung und Auflösung der Korridorstraße und auch trotz der immer wieder scharfen Kritik an den Prachtstraßen behält der monumentale Straßenraum bis heute seinen Platz in der Großstadt. Vor diesem Hintergrund will die vorliegende Arbeit auch ein Beitrag dazu sein, sich im städtischen Raum bewusst wieder mit Fragen der Morphologie und einer zeitgemäßen Monumentalität auseinanderzusetzen, wie es hier mit Blick auf das vergangene Jahrhundert anhand des monumentalen Straßenraumes vorgenommen wurde.

description: There are repetitive patterns in strategies of manipulating source code. For example, modifying source code before acquiring knowledge of how a code works is a depth-first style and reading and understanding before modifying source code is a breadth-first style. To the extent we know there is no study on the influence of personality on them. The objective of this study is to understand the influence of personality on programming styles. We did a correlational study with 65 programmers at the University of Stuttgart. Academic achievement, programming experience, attitude towards programming and five personality factors were measured via self-assessed survey. The programming styles were asked in the survey or mined from the software repositories. Performance in programming was composed of bug-proneness of programmers which was mined from software repositories, the grades they got in a software project course and their estimate of their own programming ability. We did statistical analysis and found that Openness to Experience has a positive association with breadth-first style and Conscientiousness has a positive association with depth-first style. We also found that in addition to having more programming experience and better academic achievement, the styles of working depth-first and saving coarse-grained revisions improve performance in programming.

description: In the framework of a multiorbital Hubbard model description of superconductivity, a matrix formulation of the superconducting pairing interaction that has been widely used is designed to treat spin, charge and orbital fluctuations within a random phase approximation (RPA). In terms of Feynman diagrams, this takes into account particle-hole ladder and bubble contributions as expected. It turns out, however, that this matrix formulation also generates additional terms which have the diagrammatic structure of vertex corrections. Here we examine these terms and discuss the relationship between the matrix-RPA superconducting pairing interaction and the Feynman diagrams that it sums.

description: Motivated by Planck confirmation of an anomalously low value of the CMB temperature fluctuations up to multipole $\ell<40$, we in this paper try to explain such feature by investigating case of punctuated inflation scenario. This form of inflation potential is inspired by Minimal Super-symmetric Standard Model (MSSM) wherein suppression of curvature perturbation power at large scales is produced by introducing period of fast-roll phase of the inflation sandwiched between two stages of slow-roll phase. We apply Markov Chain Monte Carlo analysis to determine posterior distribution and the best fit values of the model parameters using recent WMAP9 and Planck data. We show that WMAP9 and Planck results are consistent with each other and that with Planck data we obtain tighter constraints for punctuated inflation parameters. We find that punctuated inflation leads to better fit in CMB data compared to simple power law model. The improvement in the fit to the WMAP9 data is $Δχ^2\sim 3.6$ and for Planck the improvement is $Δχ^2\sim 5.4$. We find that $AIC$ does not discriminate between punctuated inflation and simple power law model for WMAP9 data. However, for Planck data we find that punctuated inflation is moderately preferred over a simple power law model.

description: This article demonstrates how a public research university library responded to user needs following radical service changes during Fall 2020 and assesses whether the library met challenges resulting from COVID-19. The library reduced hours and occupancy and implemented a reservation system and new health safety guidelines with the goal of a safe environment. During Fall 2020, 540 survey respondents reported feeling their health was not at risk, suggesting the goal was accomplished. Additionally, users provided feedback about the altered landscape. This article will benefit administrators and user experience librarians who need to balance user preferences and administrative reality.
