description: In the context of a nonequilibrium statistical thermodynamics, based on a nonequilibrium statistical ensemble formalism, a generalized hydrodynamics of fluids under driven flow and shear stress is derived. At the thermodynamic level, the nonequilibrium equations of state are derived, which are coupled to the evolution of the basic variables that describe the hydrodynamic motion in such a system. Generalized diffusion-advection and Maxwell-Cattaneo advection equations are obtained in appropriate limiting situations. This nonlinear higher-order hydrodynamics is applied, in an illustration, to the case of a dilute solution of Brownian particles in nonequilibrium conditions and flowing in a solvent acting as a thermal bath. This is done in the framework of such generalized hydrodynamics but truncated up to a second order.

description: We classify possible types of pseudomoduli which arise when supersymmetry is dynamically broken in infrared-free low-energy theories. We show that, even if the pseudomoduli potential is generated only at higher loops, there is a regime where the potential can be simply determined from a combination of one-loop running data. In this regime, we compute whether the potential for the various types of pseudomoduli is safe, has a dangerous runaway to the UV cutoff of the low-energy theory, or is incalculable. Our results are applicable to building new models of supersymmetry breaking. We apply the results to survey large classes of models.

description: A poly(styrene-block-methylmethacrylate) diblock copolymer in the hexagonal cylindrical phase has been used as a mask for preparing a periodic gate on top of a Ga[Al]As-heterostructure. A superlattice period of 43 nm could be imposed onto the two-dimensional electron gas. Transport measurements show a characteristic positive magnetoresistance around zero magnetic field which we interpret as a signature of electron motion guided by the superlattice potential.

Geschlechterrollen im Film im Ersten Weltkrieg am Beispiel von "Wien im Krieg" (1916)
Creators: name: Colpan, Sema Sebnem
Year: 2009

description: Die vorliegende Arbeit befasst sich mit dem Einsatz des Massenmediums Film in Österreich-Ungarn während des Ersten Weltkrieges. Dabei wird am behördlichen Propagandaspielfilm WIEN IM KRIEG aus dem Jahr 1916 exemplarisch untersucht, mit welchen Motiven und Bezügen Geschlechterbilder erzeugt wurden. Es wird die Frage aufgegriffen, mit welcher Rollenzuschreibung versucht wird, kriegsrelevante Meinung herzustellen und die Bevölkerung, insbesondere in der Heimat, zu beeinflussen. Der leider nur in Fragmenten erhaltene Film stellt eine wertvolle Quelle dar, die eine breite Palette an Ergebnissen hervorgebracht hat. Jenseits der geschlechtergeschichtlichen Zuwendung, die das Hauptaugenmerk der Analyse ausgemacht, galt es den Film einer filmhistorischen und kulturwissenschaftlichen Betrachtung zu unterziehen. WIEN IM KRIEG veranschaulicht, wie sich in der Mitte des Krieges der Umschwung von Informations- zur Unterhaltungspropaganda vollzog. Unterhaltende, narrative Elemente im Film wie auch in anderen Medien sollten der steigenden Demoralisierung in der Heimat und bei den Soldaten entgegenwirken. Die Not sollte nicht als Krise reflektiert, sondern, im Gegenteil, im öffentlichen Diskurs negiert werden. Ob das gelingt und in welchem Ausmaß auf Geschlechterrollen zurückgegriffen wird, um staatliche Interessen durchzusetzen, ist der Fokus der vorliegenden Analyse.
On the self-consistent physical parameters of LMC intermediate-age clusters

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: The LMC clusters are unique templates of simple stellar population (SSP), being crucial to calibrate models describing the integral light as well as to test the stellar evolution theory. With this in mind we analyzed HST/WFPC2 (V, B--V) colour-magnitude diagrams (CMDs) of 15 populous LMC clusters with ages between ~0.3 Gyr and ~4 Gyr using different stellar evolutionary models (Padova, PEL or Pisa, BaSTI or Teramo). Following the approach described by Kerber, Santiago & Brocato (2007), we determined accurate and self-consistent physical parameters (age, metallicity, distance modulus and reddening) for each cluster by comparing the observed CMDs with synthetic ones. We found significant trends in the physical parameters due to the choice of stellar evolutionary model and treatment of convective core overshooting. In general, models that incorporate overshooting presented more reliable results than those that do not. Comparisons with the results found in the literature demonstrated that our derived metallicities are in good agreement with the ones from the spectroscopy of red giants. We also confirmed that, independent of the adopted stellar evolutionary library, the recovered 3D distribution for these clusters is consistent with a thick disk roughly aligned with the LMC disk as defined by field stars. Finally, we also provide new estimates of distance modulus to the LMC center, that are marginally consistent with the canonical value of 18.50.

description: The plasma membrane of human red blood cells consists of a lipid bilayer attached to a regular network of underlying cytoskeletal polymers. We model this system at a dynamic coarse-grained level, treating the bilayer as an elastic sheet and the cytoskeletal network as a series of phantom entropic springs. In contrast to prior simulation efforts, we explicitly account for dynamics of the cytoskeletal network, both via motion of the protein anchors that attach the cytoskeleton to the bilayer and through breaking and reconnection of individual cytoskeletal filaments. Simulation results are explained in the context of a simple mean-field percolation model and comparison is made to experimental measurements of red blood cell fluctuation amplitudes.

Evolutionäre Hintergründe dissoziativer Phänomene
Creators: name: Lienbacher, Sabine
Year: 2009

description: Das Phänomen Dissoziation wurde bisher vor allem in der Psychologie und Psychiatrie erforscht, zunehmend werden auch mögliche evolutionäre Hintergründe diskutiert. Dissoziation wird beschrieben als strukturierte Separation mentaler Prozesse, beispielsweise von Wahrnehmung oder Emotionen. Bohus und Schmal (2006) postulieren, dass es sich bei Dissoziation um ein evolutionär entstandenes Verhaltensmuster handelt, das unter speziesspezifischem Stress aktiviert wird. Die Aktivierung von Dissoziation in lebensbedrohlichen Situationen könnte das Überflutetwerden durch überwältigende Angst- und Panikgefühle verhindern und so das Individuum in und nach der Situation handlungsfähig erhalten. Um Zusammenhänge zwischen den verschiedenen dissoziativen Phänomenen in unterschiedlichen Kontexten zu untersuchen und Rückschlüsse auf mögliche evolutionäre Hintergründe in Zusammenhang mit dem adaptiven Problem "Überleben in lebensbedrohlichen Situationen" bzw. "Generieren von Motivation" zu ziehen, wurde mittels Fragebogen ein breites Spektrum dissoziativer Phänomene und die traumatische Belastung in einer Normalpopulation erfasst (n = 142). Die Vorhersage war, dass je höher die traumatische Belastung, desto ausgeprägter die Dissoziation und die Wahrscheinlichkeit Flow-Erlebnisse zu haben. Die erfassten Phänomene sind: peritraumatische Dissoziation, Depersonalisation, Derealisation, Absorption, Flow- Erleben. Der bereits beschriebene positive Zusammenhang zwischen traumatischer Belastung und Dissoziation konnte bestätigt werden. Weiters wurden positive Zusammenhänge zwischen traumatischer Belastung und Flow-Erleben sowie zwischen peritraumatischer Dissoziation, Depersonalisation, Derealisation und Flow-Erleben gefunden. Die Ergebnisse liefern Hinweise, dass die Evolution von Dissoziation sowohl mit dem adaptiven Problem "Überleben in lebensbedrohlichen Situationen" als auch "Generieren von Motivation" in Zusammenhang stehen könnten.

description: In this paper we give a more geometrical formulation of the main theorem in [E1] on the inverse problem for the second order hyperbolic equation of general form with coefficients independent of the time variable. We apply this theorem to the inverse problem for the equation of the propagation of light in a moving medium (the Gordon equation). Then we study the existence of black and white holes for the general hyperbolic and for the Gordon equation and we discuss the impact of this phenomenon on the inverse problems.

description: For a twisted partial action Θof a group G on an (associative non-necessarily unital) algebra A over a commutative unital ring k, the crossed product A X_ΘG is proved to be associative. Given a G-graded k-algebra B = \oplus_{g\in G}\B_g with the mild restriction of homogeneous non-degeneracy, a criteria is established for B to be isomorphic to the crossed product B_1 X_ΘG for some twisted partial action of G on B_1. The equality B_g\B_{g^{-1}}B_g = \B_g for all g\in G is one of the ingredients of the criteria, and if it holds and, moreover, B has enough local units, then it is shown that B is stably isomorphic to a crossed product by a twisted partial action of G.

Performance aspects of IMS
Creators: name: Meagher, Robert Gerard
Publisher: name: University of British Columbia
Year: 2010

description: This paper deals with the tuning of the data base management system IMS. We will look at IMS in some detail; in particular, we will consider those aspects of IMS which are thought to have a measurable effect on performance at an IMS installation. These are: the original design of the data base, the adoption of logical relationships and secondary indexes and the choice of access method. Other features are thought to have a lesser effect but some of these will also be considered. These aspects will be evaluated by their ability to decrease processing time, increase flexibility and/or decrease storage requirements. The proposals presented in the first part of the paper will be further evaluated in the final chapter. The experiences of three IMS users will be incorporated to support or refute these proposals, as well as to provide insight into the kinds of performance studies being done, when they are done and what results are expected.

Abstract
For the last 20 years or so we have been designing for low power, for the next 20 years we will be designing for security. Indeed, security adds an extra design dimension, and optimizing for security is different from optimizing for power, area or throughput. It is important for IOT, mobile and cloud applications. For each of the application domains, it is important to first define the security target, otherwise stated, define the attacker model. Next, security is considered at every design abstraction layer, from applications down to technology. Because missing one link will break the security chain.

description: Spatiotemporal dynamics of electron-hole pairs locally excited in a silicon-on-insulator structure by indirect interband absorption are studied by measuring differential transmission caused by free-carrier absorption of a probe pulse tuned below the bandgap, with 200-fs temporal and 3-micrometer spatial resolution. From sample temperatures of 250 K to 400 K, the ambipolar diffusivity decreases, and is similar to reported values of bulk silicon. Cooling the sample from 250 K to 90 K, a decrease of ambipolar diffusivity is observed, indicating important influences of defects and residual stress on carrier diffusion. No detectable density dependence of ambipolar diffusivity is observed.

Using conformal perturbation theory in q-2 we compute the fractal dimension of Fortuin Kasteleyn domain walls. We also compute it numerically both via the Wolff cluster algorithm for q=3 and via transfer-matrix evaluations. We obtain numerical results for the fractal dimension of spin cluster interfaces for q=3. These are found numerically consistent with the duality kappa(spin) * kappa(FK)= 16 as expressed in putative SLE parameters.

Abstract
Successive approximation Analog to Digital Converters (SAR ADCs) have become one of the dominant types of ADC. SAR ADCs are extremely efficient when working at moderate sampling speeds and at moderate resolutions. Through interleaving, SAR ADCs can operate at very high sampling rates. This presentation traces the evolution of the SAR architecture, beginning before the IC age. Some of the techniques that make CMOS SAR ADCs so effective are highlighted. Techniques that overcome limitations of the SAR architecture are described.

description: Current long baseline experiments aim at measuring neutrino oscillation parameters with a high precision. A critical quantity is the neutrino energy which can not be measured directly but has to be reconstructed from the observed hadrons. A good knowledge of neutrino-nucleus interactions is thus necessary to minimize the systematic uncertainties in neutrino fluxes, backgrounds and detector responses. In particular final-state interactions inside the target nucleus modify considerably the particle yields through rescattering, charge-exchange and absorption. Nuclear effects can be described with our coupled channel GiBUU transport model where the neutrino first interacts with a bound nucleon producing secondary particles which are then transported out of the nucleus. In this contribution, we give some examples for the application of our model focusing in particular on the MiniBooNE and K2K experiments.

description: NGC 6240 is a luminous infrared galaxy in the local universe in the midst of a major merger. We analyze high-resolution interferometric observations of warm molecular gas using CO J = 3 - 2 and 6 - 5 in the central few kpc of NGC 6240 taken by the Atacama Large Millimeter Array. Using these CO line observations, we model the density distribution and kinematics of the molecular gas between the nuclei of the galaxies. Our models suggest that a disk model represents the data poorly. Instead, we argue that the observations are consistent with a tidal bridge between the two nuclei. We also observe high velocity redshifted gas that is not captured by the model. These findings shed light on small-scale processes that can affect galaxy evolution and the corresponding star formation.

description: MOST (Microvariability & Oscillations of STars) and ASAS (All Sky Automated Survey) observations have been used to characterize photometric variability of TW Hya on time scales from a fraction of a day to 7.5 weeks and from a few days to 8 years, respectively. The two data sets have very different uncertainties and temporal coverage properties and cannot be directly combined, nevertheless, they suggests a global variability spectrum with "flicker noise" properties, i.e. with amplitudes a ~ 1/sqrt(f), over >4 decades in frequency, in the range f = 0.0003 to 10 cycles per day (c/d). A 3.7 d period is clearly present in the continuous 11 day, 0.07 d time resolution, observations by MOST in 2007. Brightness extrema coincide with zero-velocity crossings in periodic (3.56 d) radial velocity variability detected in contemporaneous spectroscopic observations of Setiawan et al. (2008) and interpreted as caused by a planet. The 3.56/3.7 d periodicity was entirely absent in the second, four times longer MOST run in 2008, casting doubt on the planetary explanation. Instead, a spectrum of unstable single periods within the range of 2 - 9 days was observed; the tendency of the periods to progressively shorten was well traced using the wavelet analysis. The evolving periodicities and the overall flicker-noise characteristics of the TW Hya variability suggest a combination of several mechanisms, with the dominant ones probably related to the accretion processes from the disk around the star.

Abstract
Switched Mode Power Converters are important building blocks for energy efficient systems. Traditionally we have seen inductive power converter, more recently switched capacitor power converters. Each has their strengths and weaknesses. A new class of hybrid converters tries to combine inductors and capacitors to overcome those weaknesses. This talk presents 4 example designs that show the potential of such hybrids.

Multilingualismus in Katalonien und in der Ukraine
Creators: name: Siderits, Robert
Year: 2018

description: Diese Arbeit befasst sich mit den Mehrsprachigkeitssituationen in zwei europäischen Gebieten, die sich derzeit in einem Sezessionskonflikt befinden: Katalonien und Ukraine. Es wird untersucht, inwiefern man diese Sprachsituationen vergleichen kann und worin sie sich unterscheiden. Der Fokus liegt auf dem Verhältnis zwischen den jeweils wichtigsten Sprachen, also zwischen Katalanisch und Spanisch sowie zwischen Ukrainisch und Russisch. Der katalanischen und der ukrainischen Sprache wird besondere Aufmerksamkeit geschenkt, im Fall des Katalanischen wird auch dessen Status außerhalb Kataloniens beleuchtet. Nachdem eine Klärung wichtiger Begriffe erfolgt und kurz der internationale Schutz von (Minderheiten-)Sprachen erläutert wird, werden die Mehrsprachigkeitssituationen getrennt voneinander analysiert und anschließend miteinander verglichen. Im Konkreten wird jeweils auf die Geschichte des Gebiets und der Mehrsprachigkeit, auf den tatsächlichen Sprachgebrauch und auf Sprachenpolitik eingegangen. Um den Sprachgebrauch darzustellen, werden u.a. Statistiken und Umfragen herangezogen, wobei auch versucht wird, Veränderungen im Zeitverlauf darzustellen. Für die Analyse der Sprachenpolitik wird auch einschlägige Gesetzgebung verwendet. Zu den wichtigsten Gemeinsamkeiten der beiden Mehrsprachigkeitssituationen zählt, dass sich jeweils die „eigene“ Sprache des Gebietes und die größere Sprache eines historisch dominanten Staates gegenüberstehen; dieser ist im Fall Kataloniens Spanien und im Fall der Ukraine das Russische Reich bzw. die Sowjetunion. Historisch gemein haben Katalonien und die Ukraine Phasen der Unterdrückung des Katalanischen bzw. des Ukrainischen. Auch bezüglich der Sprachverwendung haben die beiden Gebiete gemeinsam, dass trotz Förderung der „eigenen“ Sprache, u.a. in der Bildung, in gewissen Bereichen wie dem Medienkonsum Spanisch bzw. Russisch weiterhin dominiert. Unterschiedlich ist hingegen die Verbreitung der Sprache in den beiden Gebieten. In der Ukraine lassen sich gewisse Teile des Landes der einen oder der anderen Sprache zuordnen, während praktisch in ganz Katalonien beide großen Sprachen gesprochen werden. Auch die Sprachenpolitik Kataloniens unterscheidet sich stark von jener der Ukraine. Während in Katalonien Katalanisch und Spanisch grundsätzlich denselben Status genießen, ist Ukrainisch die einzige Staatssprache der Ukraine. Gegner der Aufwertung des Russischen fürchten um die Stellung des Ukrainischen.

description: The simplest prescription for building a patterned structure from its constituents is to add particles, one at a time, to an appropriate template. However, self-organizing molecular and colloidal systems in nature can evolve in much more hierarchical ways. Specifically, constituents (or clusters of constituents) may aggregate to form clusters (or clusters of clusters) that serve as building blocks for later stages of assembly. Here we evaluate the character and consequences of such collective motion in a set of prototypical assembly processes. We do so using computer simulations in which a system's capacity for hierarchical dynamics can be controlled systematically. By explicitly allowing or suppressing collective motion, we quantify its effects. We find that coarsening within a two dimensional attractive lattice gas (and an analogous off-lattice model in three dimensions) is naturally dominated by collective motion over a broad range of temperatures and densities. Under such circumstances, cluster mobility inhibits the development of uniform coexisting phases, especially when macroscopic segregation is strongly favored by thermodynamics. By contrast, the assembly of model viral capsids is not frustrated but is instead facilitated by collective moves, which promote the orderly binding of intermediates consisting of several monomers.

description: We consider the problem of slow activation dynamics in glassy systems undergoing a random first order phase transition. Using an effective potential approach to supercooled liquids, we determine the spectrum of activation barriers for entropic droplets. We demonstrate that fluctuations of the configurational entropy and of the liquid glass surface tension are crucial to achieve an understanding of the barrier fluctuations in glassy systems and thus are ultimatively responsible for the broad spectrum of excitations and heterogeneous dynamics in glasses. In particular we derive a relation between the length scale for dynamic heterogeneity and the related barrier fluctuations. Diluted entropic droplets are shown to have a Gaussian distribution of barriers, strongly suggesting that non-Gaussian behavior results from droplet-droplet interactions.

description: We review recent progress in embedding the supersymmetric standard model into string theory. We discuss how, with the incorporation of certain aspects of grand unification, a search strategy can be developed that allows to efficiently find rather large numbers of promising string vacua. Global string-derived models with the following features are discussed: (i) exact MSSM spectrum below the unification scale; (ii) R parity; (iii) hierarchical Yukawa couplings with non-trivial mixing; (iv) solution to the mu problem; (v) see-saw suppressed neutrino masses.

Abrikosov flux-lines in two-band superconductors with mixed dimensionality

description: We study vortex structure in a two-band superconductor, in which one band is ballistic and quasi-two-dimensional (2D), and the other is diffusive and three-dimensional (3D). A circular cell approximation of the vortex lattice within the quasiclassical theory of superconductivity is applied to a recently developed model appropriate for such a two-band system [Tanaka et al 2006 Phys. Rev. B 73, 220501(R); Tanaka et al 2007 Phys. Rev. B 75, 214512]. We assume that superconductivity in the 3D diffusive band is "weak", i.e., mostly induced, as is the case in MgB$_2$. Hybridization with the "weak" 3D diffusive band has significant and intriguing influence on the electronic structure of the "strong" 2D ballistic band. In particular, the Coulomb repulsion and the diffusivity in the "weak" band enhance suppression of the order parameter and enlargement of the vortex core by magnetic field in the "strong" band, resulting in reduced critical temperature and field. Moreover, increased diffusivity in the "weak" band can result in an upward curvature of the upper critical field near the transition temperature. A particularly interesting feature found in our model is the appearance of additional bound states at the gap edge in the "strong" ballistic band, which are absent in the single-band case. Furthermore, coupling with the "weak" diffusive band leads to reduced band gaps and van Hove singularities of energy bands of the vortex lattice in the "strong" ballistic band. We find these intriguing features for parameter values appropriate for MgB$_2$.

description: We extend the finite-temperature Keldysh non-equilibrium coupled cluster theory (Keldysh-CC) [{\it J. Chem. Theory Comput.} \textbf{2019}, 15, 6137-6253] to include a time-dependent orbital basis. When chosen to minimize the action, such a basis restores local and global conservation laws (Ehrenfest's theorem) for all one-particle properties, while remaining energy conserving for time-independent Hamiltonians. We present the time-dependent orbital-optimized coupled cluster doubles method (Keldysh-OCCD) in analogy with the formalism for zero-temperature dynamics, extended to finite temperatures through the time-dependent action on the Keldysh contour. To demonstrate the conservation property and understand the numerical performance of the method, we apply it to several problems of non-equilibrium finite-temperature dynamics: a 1D Hubbard model with a time-dependent Peierls phase, laser driving of molecular H$_2$, driven dynamics in warm-dense silicon, and transport in the single impurity Anderson model.

Die objektive Schiedsfähigkeit nach österreichischem Recht
Creators: name: Voit, Ulrich
Year: 2009

description: Die objektive Schiedsfähigkeit nach österreichischem Recht (nach dem SchiedsRÄG 2006) beschäftigt sich damit, zu determinieren, welcher Streitgegenstand vor einem Schiedsgericht verhandelt werden kann oder nicht. Dabei bedarf es zunächst einer Analyse des Begriffes der objektiven Schiedsfähigkeit. In weiterer Folge ist diese Begriffsanalyse auf Streitgegenstände (außerstreitige Rechtssachen, Beschlussmängelstreitigkeiten, exekutionsrechtliche Klagen) umzulegen und zu überprüfen, was für eine Auswirkung diese, durch den Staat gezogene Trennlinie, auf den jeweiligen Streitgegenstand hat. Es wurde dabei auch rechtsvergleichend auf die Rechtslage in Deutschland und der Schweiz eingegangen,weil das österreichische Recht von diesen Rechtslagen beeinflusst ist. Zuletzt wurde untersucht, welche Rechtsfolgen die mangelnde objektive Schiedsfähigkeit hat.
