description: Potenzialtheoretisch werden stationäre und instationäre Aspekte bei Umströmung von Schiffspropellern untersucht. Sowohl für die Berechnung von hydroelastischen Effekten über eine Fluid-Struktur-Wechselwirkung als auch für die Prognose des Einsatzpunktes von Spitzenwirbelkavitation werden spezielle Modelle entwickelt und analysiert. Das zu diesem Zweck eigens entwickelte potenzialtheoretische Rechenverfahren, ein über Propelleranwendungen hinausreichendes instationäres 3D-Paneelverfahren, wird dargestellt und umfangreich validiert.
description: Based on potential theory stationary and transient propeller flows are analyzed. The developed general purpose panel method is described in detail and validated for ship propellers. A new method is generated for the prediction of tip vortex cavitation inception. The results are compared to measurements in homogeneous and inhomogeneous wake fields. Further the transient hydroelastic behavior of a propeller in an unsteady ship wake is simulated via an implicit coupling to a inite-element method. Different coupling approaches are analyzed and the influencing parameters of the elastic effects are assessed.

description: In this Letter we present a new perspective for the study of the Public Goods games on complex networks. The idea of our approach is to consider a realistic structure for the groups in which Public goods games are played. Instead of assuming that the social network of contacts self-defines a group structure with identical topological properties, we disentangle these two interaction patterns so to deal with systems having groups of definite sizes embedded in social networks with a tunable degree of heterogeneity. Surpisingly, this realistic framework, reveals that social heterogeneity may not foster cooperation depending on the game setting and the updating rule.

description: It is well known that boundary conditions on quantum fields produce divergences in the renormalized energy-momentum tensor near the boundaries. Although irrelevant for the computation of Casimir forces between different bodies, the self-energy couples to gravity, and the divergences may, in principle, generate large gravitational effects. We present an analysis of the problem in the context of quantum field theory in curved spaces. Our model consists of a quantum scalar field coupled to a classical field that, in a certain limit, imposes Dirichlet boundary conditions on the quantum field. We show that the model is renormalizable and that the divergences in the renormalized energy-momentum tensor disappear for sufficiently smooth interfaces.

description: Frugal innovations are increasingly considered in the context of sustainability and are seen to have promising potential for the realization of global sustainability goals. So far, the discourse has focused on the question of whether and how frugal innovations contribute to sustainable development without presenting concrete guidelines and principles. Through a systematic literature review guiding principles are therefore derived, conceptualized in the motivational context of emerging and industrialized economies and empirically illustrated using the example of Western automotive companies. The principles can be used to further substantiate the link between frugal innovations and corporate sustainability as well as to use them for the development of green(er) innovation.

description: Computational grids are believed to be the ultimate framework to meet the growing computational needs of the scientific community. Here, the processing power of geographically distributed resources working under different ownerships, having their own access policy, cost structure and the likes, is logically coupled to make them perform as a unified resource. The continuous increase of availability of high-bandwidth communication as well as powerful computers built of low-cost components further enhance chances of computational grids becoming a reality. However, the question of grid security remains one of the important open research issues. Here, we present some novel ideas about how to implement grid security, without appreciable performance degradation in grids. A suitable alternative to the computationally expensive encryption is suggested, which uses a key for message authentication. Methods of secure transfer and exchange of the required key(s) are also discussed.

Molecular biology grade lyophilized powder of Recombinant Proteinase K
Creators: name: , Lisa
Publisher: name: Zenodo
Year: 2023

description: Proteinase K is a broad-spectrum serine protease originally isolated from the fungus Engyodontiumalbum (Tritirachium album). The enzyme was named "proteinase K" for its ability to digest keratin. Structural and molecular biology studies suggest that the enzyme belongs to the subtilisin family characterized by a catalytic triad (Asp39-His9-Ser2) in the active site. Proteinase K has no pronounced cleavage specificity and the preferential cleavage site is the peptide bond adjacent to hydrophobic amino acids.

description: We consider the effect of quenched spatial disorder on systems of interacting, pinned non-Abelian anyons as might arise in disordered Hall samples at filling fractions ν=5/2 or ν=12/5. In one spatial dimension, such disordered anyon models have previously been shown to exhibit a hierarchy of infinite randomness phases. Here, we address systems in two spatial dimensions and report on the behavior of Ising and Fibonacci anyons under the numerical strong-disorder renormalization group (SDRG). In order to manage the topology-dependent interactions generated during the flow, we introduce a planar approximation to the SDRG treatment. We characterize this planar approximation by studying the flow of disordered hard-core bosons and the transverse field Ising model, where it successfully reproduces the known infinite randomness critical point with exponent ψ~ 0.43. Our main conclusion for disordered anyon models in two spatial dimensions is that systems of Ising anyons as well as systems of Fibonacci anyons do not realize infinite randomness phases, but flow back to weaker disorder under the numerical SDRG treatment.

description: We measured the resistivity and magnetic susceptibility to map out the phase diagram of single crystalline NaFe$_{1-x}$Co$_x$As. Replacement of Fe by Co suppresses both the structural and magnetic transition, while enhances the superconducting transition temperature ($T_{\rm c}$) and superconducting component fraction. Magnetic susceptibility exhibits temperature-linear dependence in the high temperatures up to 500 K for all the superconducting samples, but such behavior suddenly breaks down for the non-superconducting overdoped crystal, suggesting that the superconductivity is closely related to the T-linear dependence of susceptibility. Analysis on the superconducting-state specific heat for the optimally doped crystal provides strong evidence for a two-band s-wave order parameter with gap amplitudes of $Δ_1(0)/k_{\rm B}T_{\rm c}$= 1.78 and $Δ_2(0)/k_{\rm B}T_{\rm c}$=3.11, being consistent with the nodeless gap symmetry revealed by angle-resolved photoemission spectroscopy experiment.

A wave-pinning mechanism for eukaryotic cell polarization based on Rho GTPase dynamics
Creators: name: Jilkine, Alexandra
Publisher: name: University of British Columbia
Year: 2010

description: In response to chemical stimulation, many eukaryotic cells are able to sense the direction of the stimulus and initiate movement. To do so, the cell must break symmetry and develop a front and back in a process known as polarization. During polarization, members of the Rho GTPase family (Cdc42, Rac, and Rho) are recruited to the plasma membrane and localize to form a front and a back of the polarizing cell. These proteins exist in both active forms (on the inner surface of the membrane of the cell), and inactive forms (in the cytosol). In earlier work, I have shown that the property of membrane-cytosol interconversion, together with appropriate feedbacks, endows the Rho proteins with the ability to initiate cell polarity, resulting in a high Cdc42/Rac region, which will become the front, and a high Rho region, which will become the back of the cell. Here I show that this property of polarizability can be explained using a simplified model system comprising of a single active/inactive protein pair with positive feedback. In this model, a travelling wave of GTPase activation is initiated at one end of the domain, moves across the cell, and eventually stops inside the domain, resulting in a stable polar distribution. The key requirements for the mechanism to work include conservation of total amount of protein, a sufficiently large difference in diffusion rates of the two forms, and nonlinear positive feedback that allows for multiple homogeneous steady states to exist. Using singular perturbation theory, I explain the mathematical basis of wave-pinning behaviour, and discuss its biological and mathematical implications. I show that this mechanism for generating a chemical pattern is distinct from Turing pattern formation. I also analyze the transition from a spatially heterogeneous solution to a spatially homogeneous solution as the diffusion coefficient of the active form is increased, and show the existence of other unstable stationary wavefronts. Finally, I argue that this wave-pinning mechanism can account for a number of features of cell polarization such as spatial amplification, maintenance of polarity, and the sensitivity to new stimuli that is typical of polarization of eukaryotic cells.

description: We study the introduction of a third material, namely Zr, within a nanometric periodic Mg/Co structure designed to work as optical component in the extreme UV (EUV) spectral range. Mg/Co, Mg/Zr/Co, Mg/Co/Zr and Mg/Zr/Co/Zr multilayers are designed, then characterized in terms of structural quality and optical performances through X-ray and EUV reflectometry measurements respectively. For the Mg/Co/Zr structure, the reflectance value is equal to 50% at 25.1 nm and 45deg of grazing incidence and reaches 51.3% upon annealing at 200deg C. Measured EUV reflectivity values of tri-layered systems are discussed in terms of material order within a period and compared to the predictions of the theoretical model of Larruquert. Possible applications are pointed out.

description: The leading hadronic effects in electroweak theory derive from vacuum polarization which are non-perturbative hadronic contributions to the running of the gauge couplings, the electromagnetic alpha_{em}(s) and the SU(2)_L coupling alpha_2(s). I will report on my recent package "alphaQED", which besides the effective fine structure constant alpha_{em}(s) also allows for a fairly precise calculation of the SU(2)_L gauge coupling alpha_2(s). I will briefly review the role, future requirements and possibilities. Applied together with the "Rhad" package by Harlander and Steinhauser, the package allows to calculate all SM running couplings as well as running sin^2 Theta versions with state-of-the-art accuracy.

On combining acoustic and modulation spectrograms in an attention LSTM-based system for speech intelligibility level classification

description: Speech intelligibility can be affected by multiple factors, such as noisy environments, channel distortions or physiological issues. In this work, we deal with the problem of automatic prediction of the speech intelligibility level in this latter case. Starting from our previous work, a non-intrusive system based on LSTM networks with attention mechanism designed for this task, we present two main contributions. In the first one, it is proposed the use of per-frame modulation spectrograms as input features, instead of compact representations derived from them that discard important temporal information. In the second one, two different strategies for the combination of per-frame acoustic log-mel and modulation spectrograms into the LSTM framework are explored: at decision level or late fusion and at utterance level or Weighted-Pooling (WP) fusion. The proposed models are evaluated with the UA-Speech database that contains dysarthric speech with different degrees of severity. On the one hand, results show that attentional LSTM networks are able to adequately modeling the modulation spectrograms sequences producing similar classification rates as in the case of log-mel spectrograms. On the other hand, both combination strategies, late and WP fusion, outperform the single-feature systems, suggesting that per-frame log-mel and modulation spectrograms carry complementary information for the task of speech intelligibility prediction, than can be effectively exploited by the LSTM-based architectures, being the system with the WP fusion strategy and Attention-Pooling the one that achieves best results.

description: We study N=2 supersymmetric SU(2) gauge theories coupled to non-Lagrangian superconformal field theories induced by compactifying the six dimensional A_1 (2,0) theory on Riemann surfaces with irregular punctures. These are naturally associated to Hitchin systems with wild ramification whose spectral curves provide the relevant Seiberg-Witten geometries. We propose that the prepotential of these gauge theories on the Omega-background can be obtained from the corresponding irregular conformal blocks on the Riemann surfaces via a generalization of the coherent state construction to the case of higher order singularities.

The aetilology of error : cognitive profiling events within the mine workplace
Creators: name: Sweeney, E. Douglas
Publisher: name: University of British Columbia
Year: 2010

description: Investigation of accidents, incidents and other unintended events in the workplace continues to evolve in the mining industry, as it has for other heavy industries. Traditional investigation approaches are grounded in causation – the determination of cause and effect relationships manifested by the evidentiary record. This approach, while intuitive and widely accepted, is not inclusive of the more distal elements of causality such as the influence of cognitive error and the perception of risk. This research examines the role of cognitive error in decisions that contribute to events; the nature of these errors and how they are indicative of organizational culture. The main objective of this research is to develop and evaluate a cognitive error tool that can be used in the analysis of events within the mining industry. The current taxonomies are few, and are not available in a robust and structured model easily applied by accident investigators. This research seeks to address this by offering a theory of event causality based upon decision errors (Decision Error); taxonomy of decision errors (Lost Error); and, a model for profiling cognitive error (Cognitive Profiling). Further, through cognitive profiling, it will be shown that there is a collective, or distributed, cognition that exists precursory to an event that heretofore has not been addressed by conventional causation modelling of events in the mine workplace. This research contributes to the field of human error analysis by proposing taxonomy based upon decision errors; and to the field of cognitive science by examining the role that risk perception has in cognition within the workplace. It provides a lexicon and a methodology that is exploratory in determining those events in the mine enterprise that are prone to escalation toward disaster; and by what errors in management such outcomes can be triggered. This research contributes to the field of accident theory and investigation by expanding on the notion of causation to include causality. It is shown that when events and their investigation are considered as systems with inputs, outputs, and processes; then there is another system at play – the human error system that is antecedent to events.

description: NGC2264 is a young cluster with a rich circumstellar disk population which makes it an ideal target for studying the evolution of stellar clusters. Our goal is to study its star formation history and to analyse the primordial disk evolution of its members. The study presented is based on data obtained with Spitzer IRAC and MIPS, combined with deep NIR ground-based FLAMINGOS imaging and previously published optical data. We build NIR dust extinction maps of the molecular cloud associated with the cluster, and determine it to have a mass of 2.1x10^3Msun above an Av of 7mag. Using a differential K_s-band luminosity function of the cluster, we estimate the size of its population to be 1436$\pm$242 members. The star formation efficiency is ~25%. We identify the disk population: (i) optically thick inner disks, (ii) anaemic inner disks, and (iii) disks with inner holes, or transition disks. We analyse the spatial distribution of these sources and find that sources with thick disks segregate into sub-clusterings, whereas sources with anaemic disks do not. Furthermore, sources with anaemic disks are found to be unembedded (Av<3mag), whereas the clustered sources with thick disks are still embedded within the parental cloud. NGC2264 has undergone more than one star-forming event, where the anaemic and extincted thick disk population appear to have formed in separate episodes. We also find tentative evidence of triggered star-formation in the Fox Fur Nebula. In terms of disk evolution, our findings support the emerging disk evolution paradigm of two distinct evolutionary paths for primordial optically thick disks: a homologous one where the disk emission decreases uniformly at NIR and MIR wavelengths, and a radially differential one where the emission from the inner region of the disk decreases more rapidly than from the outer region (forming transition disks).

description: Formation Gibbs free energy of point defects and oxygen clusters in uranium dioxide at high-pressure high-temperature conditions are calculated from first principles, using the LSDA+U approach for the electronic structure and the Debye model for the lattice vibrations. The phonon contribution on Frenkel pairs is found to be notable, whereas it is negligible for the Schottky defect. Hydrostatic compression changes the formation energies drastically, making defect concentrations depend more sensitively on pressure. Calculations show that, if no oxygen clusters are considered, uranium vacancy becomes predominant in overstoichiometric UO2 with the aid of the contribution from lattice vibrations, while compression favors oxygen defects and suppresses uranium vacancy greatly. At ambient pressure, however, the experimental observation of predominant oxygen defects in this regime can be reproduced only in a form of cuboctahedral clusters, underlining the importance of defect clustering in UO2+x. Making use of the point defect model, an equation of state for non-stoichiometric oxides is established, which is then applied to describe the shock Hugoniot of UO2+x. Furthermore, the oxidization and compression behavior of uranium monoxide, triuranium octoxide, uranium trioxide, and a series of defective UO2 at zero Kelvin are investigated. The evolution of mechanical properties and electronic structures with an increase of the oxidation degree are analyzed, revealing the transition of the groundstate of uranium oxides from metallic to Mott insulator and then to charge-transfer insulator due to the interplay of strongly correlated effects of 5f orbitals and the shift of electrons from uranium to oxygen atoms.

description: Das Ziel der vorliegenden Arbeit ist die experimentelle und theoretische Untersuchung des Ermüdungsverhaltens der laserstrahlgeschweißten Titan-Legierung Ti-6Al-4V im Bereich von hohen Lastzyklen. Die werkstoffmechanischen Vorgänge der Rissinitiierung in der Schweißnaht und Einfluss von Schweißfehlern auf die Ermüdungseigenschaften wurden ausführlich erforscht. Verschiedene Arten von Behandlungsverfahren nach dem Schweißen mit dem Ziel, die Lebensdauer der geschweißten Strukturen zu erhöhen, wurden analysiert. Abschließend wurde ein bruchmechanisches Berechnungsmodell entwickelt, welche die Abschätzung der Dauerfestigkeit von Schweißverbindungen und deren Streuung mit hinreichender Genauigkeit ermöglicht.
description: This aim of this work is to investigate the fatigue behaviour of laser-welded Ti-6Al-4V titanium alloy in the region of high cycle fatigue. The crack initiation mechanism and the influence of weld defects on fatigue performance were comprehensively studied. A set of post-weld treatments that can mitigate the effect of inherent weld imperfections and thereby extend the fatigue life were analysed. A robust and efficient analytical assessment model for internally-flawed materials has been developed based on a fracture mechanics approach. The developed methodology can be used for the reliability assessment of components with various types of defects, thus enabling a defect-tolerant design of welded structures.

Stellar scattering and the origin of the planet around gamma-cephei-A

description: In the last years several exoplanets have been discovered that orbit one component of a compact binary system (separation < 50 astronomical units), the probably best-known case is gamma-Cephei. So far, all attempts to explain the in-situ formation of these planets has been unsuccessful, in part because of the strong gravitational perturbations of the secondary star on any initial planetesimal swarm. Here we test whether planetary bodies in compact binaries, in particular gamma-Cephei, could have originated from a close encounter with a passing star, assuming initial configurations for the stellar system suitable for planetary formation. In other words, we analyze whether the orbital configuration of the current binary system might have been generated after the formation of the planet, and as a consequence of a close encounter with a third star in hyperbolic orbit. We performed a series of time-reverse N-body simulations of stellar scattering events in which the present-day configuration of gamma-Cephei was used as the initial condition plus a hypothetical third star as an impactor. We analyzed which configurations and system parameters could have given birth to the current system. Depending on the maximum impact velocity allowed for accretional collisions, we find that between 1% and 5% of stellar encounters correspond to an "original" system in which planetary formation around the primary star is not inhibited by the secondary, but is acceptable within the classical core-accretion scenario. Thus, although not highly probable, it is plausible that stellar encounters may have played a significant role in shaping these types of exoplanetary systems.

description: In this paper we study the functional $\SW_{λ_1,λ_2}$, which is the the sum of the Willmore energy, $λ_1$-weighted surface area, and $λ_2$-weighted volume, for surfaces immersed in $\R^3$. This coincides with the Helfrich functional with zero `spontaneous curvature'. Our main result is a complete classification of all smooth immersed critical points of the functional with $λ_1\ge0$ and small $L^2$ norm of tracefree curvature. In particular we prove the non-existence of critical points of the functional for which the surface area and enclosed volume are positively weighted.

Ontological oppression and the privatization of public potential: indigenous counter-hegemonic adaptation in São Paulo, Brazil
Creators: name: Ferrari-Nunes, Rodrigo
Publisher: name: University of British Columbia
Year: 2010

description: This study focuses on an analysis of the counter-hegemonic discourse of Guarani indigenous leaders Timóteo Verá Popyguá and Marçal de Souza, focusing on the strategy of envolvimento (involvement) with the larger capitalist world as a means for achieving cultural survival and autonomy. The core idea of this study is how the 'privatization of public potential' can be employed both for and against initiatives that foster the strengthening of indigenous ways of knowing and relating with the land. I argue that, in order to subvert private property and the domination of space for capitalist production, envolvimento seeks the privatization of lands for the Guarani, who will develop this parcel of land according to their own cultural principles. Counter-hegemonic adaptation, in this case, requires a deep understanding of dominant practices and ideologies, and the desire to take part in the larger economy. Ultimately, I argue that the negative effects of neoliberalism can be diminished by making more private spaces communal.
A classification theorem on Fano bundles

description: In this paper we classify rank two Fano bundles $\cE$ on Fano manifolds satisfying $H^2(X,\Z)\cong H^4(X,\Z)\cong\Z$. The classification is obtained via the computation of the nef and pseudoeffective cones of the projectivization ${\mathbb{P}}(\cE)$, that allows us to obtain the cohomological invariants of $X$ and $\cE$. As a by-product we discuss Fano bundles associated to congruences of lines, showing that their varieties of minimal rational tangents may have several linear components.

description: Manufacturers usually benefit by dividing their innovation processes into distinct phases in order to ensure that the development activities are performed efficiently in an appropriate sequence. Users usually do not apply such structured processes. They follow a more intuition-driven approach. In this paper we analyze the way users improve or develop novel products. The field of our research is a new and rapidly evolving consumer market, the sport of kite surfing.
 We identified a sequence that underlies the approaches of user inventors. This sequence consists of two major stages, (1) idea generation and (2) idea realization, each again subdivided. We propose that a manufacturer in the relevant product field can significantly profit from more closely observing such user activities:
 • Better understanding of tacit needs which cannot be derived by applying classical market research methods.
 • Learn about the adequacy of solutions from the user. This may guide their
 development activities and prevent development of inadequate solutions.
 • Collect user ideas as well as corresponding solution knowledge at very low tariffs and increase reputation as a customer-close organization.
Addendum to "Thin-shell wormholes supported by ordinary matter in Einstein-Gauss-Bonnet gravity"

description: Thin-shell wormholes are constructed starting from the exotic branch of Wiltshire spherically symmetric solution of Einstein-Gauss-Bonnet gravity. The energy-momentum tensor of the shell is studied, and it is shown that configurations supported by matter satisfying the energy conditions exist for certain values of the parameters. Differing from the previous result associated to the normal branch of Wiltshire solution, this is achieved for small positive values of the Gauss-Bonnet parameter and for vanishing charge.

description: The advent of transformation optics and metamaterials has made possible devices producing extreme effects on wave propagation. Here we give theoretical designs for devices, Schrödinger hats, acting as invisible concentrators of waves. These exist for any wave phenomenon modeled by either the Helmholtz or Schrödinger equations, e.g., polarized waves in EM, pressure waves in acoustics and matter waves in QM, and occupy one part of a parameter space continuum of wave-manipulating structures which also contains standard transformation optics based cloaks, resonant cloaks and cloaked sensors. For EM and acoustic Schrödinger hats, the resulting centralized wave is a localized excitation. In QM, the result is a new charged quasiparticle, a \emph{quasmon}, which causes conditional probabilistic illusions. We discuss possible solid state implementations.
