description: We conduct searches for continuous gravitational waves from seven pulsars, that have not been targeted in continuous wave searches of Advanced LIGO data before. We target emission at exactly twice the rotation frequency of the pulsars and in a small band around such frequency. The former search assumes that the gravitational wave quadrupole is changing phase-locked with the rotation of the pulsar. The search over a range of frequencies allows for differential rotation between the component emitting the radio signal and the component emitting the gravitational waves, for example the crust or magnetosphere versus the core. Timing solutions derived from the Arecibo 327-MHz Drift-Scan Pulsar Survey (AO327) observations are used. No evidence of a signal is found and upper limits are set on the gravitational wave amplitude. For one of the pulsars we probe gravitational wave intrinsic amplitudes just a factor of 3.8 higher than the spin-down limit, assuming a canonical moment of inertia of $10^{38}$ kg m$^2$. Our tightest ellipticity constraint is $1.5 \times 10^{-8}$, which is a value well within the range of what a neutron star crust could support.

description: F.W. Bernstein, Bernd Eilert, Robert Gernhardt, Eckhard Henscheid, Peter 'Pit' Knorr, Chlodwig Poth, Hans Traxler und F.K. Waechter firmieren seit 1981 unter dem Namen "Neue Frankfurter Schule" (NFS). Die Künstlergruppe, die sich in den 1960er Jahren um das Satiremagazin "Pardon" gebildet hat, zeichnete sich im Jahr 1979 für die Gründung des endgültigen Satiremagazins "TITANIC" verantwortlich. Ihr Werk ist maßgeblich für die Entwicklung von Komik und Komischer Kunst in der Bundesrepublik Deutschland. In der Forschung sind Werk und Gruppe jedoch unterrepräsentiert. Die vorliegende Arbeit erarbeitet im ersten Teil deshalb auf Gebiet der Komiktheorie ein fachsprachliches Instrumentarium, um das Werk der NFS literaturwissenschaftlich adäquat fassen zu können. Im zweiten Teil werden die Autoren der NFS wissenschaftlich portraitiert und die literaturhistorischen Begebenheit zur Entstehung der Gruppe geklärt. Dabei wird der Versuch unternommen, das Gesamtwerk der NFS zu erfassen, Entwicklungslinien aufzuzeigen und den Anschluss an die "Frankfurter Schule" herzustellen. Die vorliegende Arbeit entwickelt hierbei die Theorie von der Leistungsfähigkeit der Komik als "Seismograph historischer Ereignisse" und demonstriert dies anhand des Werks der NFS.

description: In an experiment reported recently [Phys. Rev. Lett. 100, 133601 (2008)], we demonstrated that, through group velocity matched parametric downconversion, heralded single photons can be generated in pure quantum states without spectral filtering. The technique relies on factorable photon pair production, initially developed theoretically in the strict collinear regime; focusing - required in any experimental implementation - can ruin this factorability. Here we present the numerical model used to design our single photon sources and minimize spectral correlations in the light of such experimental considerations. Furthermore, we show that the results of our model are in good agreement with measurements made on the photon pairs and give a detailed description of the exact requirements for constructing this type of source.

description: In September 2019, the Council of Europe's Committee of Ministers adopted the terms of reference for the Ad Hoc Committee on Artificial Intelligence (CAHAI). The CAHAI is charged with examining the feasibility and potential elements of a legal framework for the design, development, and deployment of AI systems that accord with Council of Europe standards across the interrelated areas of human rights, democracy, and the rule of law. As a first and necessary step in carrying out this responsibility, the CAHAI's Feasibility Study, adopted by its plenary in December 2020, has explored options for an international legal response that fills existing gaps in legislation and tailors the use of binding and non-binding legal instruments to the specific risks and opportunities presented by AI systems. The Study examines how the fundamental rights and freedoms that are already codified in international human rights law can be used as the basis for such a legal framework. The purpose of this primer is to introduce the main concepts and principles presented in the CAHAI's Feasibility Study for a general, non-technical audience. It also aims to provide some background information on the areas of AI innovation, human rights law, technology policy, and compliance mechanisms covered therein. In keeping with the Council of Europe's commitment to broad multi-stakeholder consultations, outreach, and engagement, this primer has been designed to help facilitate the meaningful and informed participation of an inclusive group of stakeholders as the CAHAI seeks feedback and guidance regarding the essential issues raised by the Feasibility Study.

description: Digital Literacy is an increasingly important aspect of teaching in our digitally advanced world. Digital skills are also essential in the workplace. Digital Literacies are continuously developing and therefore it is the Higher Education Institution’s responsibility to engage with these developments and prepare students for this digital landscape. This study aimed to define Digital Literacy and to identify the capabilities required to be Digitally Literate in the context of marketing in the contemporary workplace. The study explores the view of Digital Literacy from the perspective of ten undergraduate students studying marketing who had undertaken a year-long placement. It aimed to understand the role and potential that Digital Literacy has in the workplace from the perspective of these students and from the perspective of the employers whom the students had worked for. In-depth, semistructured interviews were undertaken with students to explore their view of Digital Literacy before they began their placement and then on completion of their placement. Employers were interviewed to explore what they expected from students with regards to Digital Literacy. The research concluded that students recognised the role and the importance of Digital Literacy. Students’ perspectives of Digital Literacy developed throughout the placement and they became more reflective about their digital abilities. They understood the practical application of digital skills which highlighted that being Digitally Literate is about using digital tools in an applicable context. It is important for students to be adaptable to different digital tools and different contexts. Students’ capabilities in Digital Literacy developed throughout the authentic learning experience of the sandwich placement which aligned with social constructivist theory.

description: The Galilei-covariant fermionic field theories are quantized by using the path-integral method and five-dimensional Lorentz-like covariant expressions of non-relativistic field equations. Firstly, we review the five-dimensional approach to the Galilean Dirac equation, which leads to the Levy-Leblond equations, and define the Galilean generating functional and Green's functions for positive- and negative-energy/mass solutions. Then, as an example of interactions, we consider the quartic self-interacting potential $λ (\barΨ Ψ)^2$, and we derive expressions for the 2- and 4-point Green's functions. Our results are compatible with those found in the literature on non-relativistic many-body systems. The extended manifold allows for compact expressions of the contributions in $(3+1)$ space-time. This is particularly apparent when we represent the results with diagrams in the extended $(4+1)$ manifold, since they usually encompass more diagrams in Galilean $(3+1)$ space-time.

description: Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community. In the present paper we start by reviewing the basic observational and theoretical properties of classical and solar-like pulsators and present results from some of the most recent and outstanding studies of these stars. We centre our review on those classes of pulsators for which interferometric studies are expected to provide a significant input. We discuss current limitations to asteroseismic studies, including difficulties in mode identification and in the accurate determination of global parameters of pulsating stars, and, after a brief review of those aspects of interferometry that are most relevant in this context, anticipate how interferometric observations may contribute to overcome these limitations. Moreover, we present results of recent pilot studies of pulsating stars involving both asteroseismic and interferometric constraints and look into the future, summarizing ongoing efforts concerning the development of future instruments and satellite missions which are expected to have an impact in this field of research.

Cell surface of hydrophobic and hydrophilic strains of Streptococcus sanguis
Creators: name: Ganeshkumar, Nadarajah
Publisher: name: University of British Columbia
Year: 2010

description: Cell surfaces of aggregation, adherence or hydrophilic variants of Streptococcus sanguis were compared to cell surfaces of the parent strain with regard to their protein and antigenic constituents. Cell surface molecules were released by digestion with mutanolysin. Extraction with SDS-BME, urea, lithium chloride and boiling water did not solubilize any material which stained with silver nitrate in an SDS-polyacrylamide gel. The parent organism S. sanguis 12 which aggregates in saliva, adheres to saliva coated hydroxyapatite (S-HA) and is hydrophobic was found to possess a prominently staining 160,000 MW protein. This protein was almost completely absent from strain I2na, a hydrophobic non-aggregating variant, and was completely absent from the hydrophilic non-aggregating, non-adherent strain 12L. Trypsinization of strain 12 resulted in the coincident loss of the 160,000 MW protein and the ability to aggregate in saliva. Trypsin treatment reduced, but did not eliminate the hydrophobic character of the cells. Boiling destroyed the ability to aggregate but did not alter hydrophobicity. Cell wall digests of strain 12 contained a large number of proteins which were absent from strains 12na and 12L. Mutanolysin digests of the hydrophilic strains contained no material that was visible in a silver stained SDS-polyacrylamide gel. Electron microscopy of phosphotungstic acid stained cells showed a thick capsular material spread evenly over the cell surface of the parent strain 12. This layer was thinner around the cells of strain 12na and appeared patchy on hydrophilic strains. Electron microscopy of uranyl acetate stained cells revealed that strain 12 had short fibrillar structures evenly distributed over the cell surface, and long fibrils which were more concentrated at the end of the cell. The hydrophilic strain 12L lacked both types of fibrils. Crossed immunoelectrophoresis confirmed that the major cell surface antigens were located in the 160,000 MW region. Cell wall digests of strain 12 and 12na inhibited adherence of strain 12 to S-HA by 36% and 19% respectively. The digests of hydrophilic strain 12L were not inhibitory. The inhibitory activity was sensitive to heat and SDS.

description: Constructions of woven graph codes based on constituent block and convolutional codes are studied. It is shown that within the random ensemble of such codes based on $s$-partite, $s$-uniform hypergraphs, where $s$ depends only on the code rate, there exist codes satisfying the Varshamov-Gilbert (VG) and the Costello lower bound on the minimum distance and the free distance, respectively. A connection between regular bipartite graphs and tailbiting codes is shown. Some examples of woven graph codes are presented. Among them an example of a rate $R_{\rm wg}=1/3$ woven graph code with $d_{\rm free}=32$ based on Heawood's bipartite graph and containing $n=7$ constituent rate $R^{c}=2/3$ convolutional codes with overall constraint lengths $ν^{c}=5$ is given. An encoding procedure for woven graph codes with complexity proportional to the number of constituent codes and their overall constraint length $ν^{c}$ is presented.

description: We report first results of laboratory tests of Si:As blocked-impurity-band (BIB) mid-infrared (4 to 28 um) detectors developed by IMEC. These prototypes feature 88 pixels hybridized on an integrated cryogenic readout electronics (CRE). They were developed as part of a technology demonstration program for the future DARWIN mission. In order to be able to separate detector and readout effects, a custom build TIA circuitry was used to characterize additional single pixel detectors. We used a newly designed test setup at the MPIA to determine the relative spectral response, the quantum efficiency, and the dark current. All these properties were measured as a function of operating temperature and detector bias. In addition the effects of ionizing radiation on the detector were studied. For determining the relative spectral response we used a dual-grating monochromator and a bolometer with known response that was operated in parallel to the Si:As detectors. The quantum efficiency was measured by using a custom-build high-precision vacuum black body together with cold (T ~ 4 K) filters of known (measured) transmission.

Special case of the result is a finite presentation of the algebra of multisymmetric polynomials. Reducedness of the invariant commuting scheme is proved as a by-product. The algebra of multisymmetric polynomials over an arbitrary base ring is revisited.

Galaxy Bulges at Mid and High-Redshift

description: Bulges are a major galaxy component in the nearby universe, and are one of the primary features that differentiates and defines galaxies. The origin of bulges can be directly probed in part by examining distant galaxies to search for high redshift bulges, and to study the properties of bulges in formation. We review the evidence for bulges at high redshift in this article, and how by studying bulges through a variety of approaches, including morphological, colour, and stellar mass selection, we can determine when and how these systems assembled. We argue that the majority of the most massive 'classical' bulges are in place by z ~ 1.5 - 2, and likely formed very early through major mergers. Other, likely lower mass, bulges form through a secular process along with their disks. Direct observations suggest that these two formation processes are occurring, as spheroids are commonly seen at z > 1, as are disks and spiral galaxies in the form of luminous diffuse objects, clump-clusters, and chain galaxies. However, bulge+disk systems are relatively rare until z ~ 1, suggesting that this structural assembly occurred relatively late.

The calculation is done for closed and open spin chains. In this latter case, the boundary matrices $K_{\pm}(u)$ are of general type, provided they commute. We compute the Bethe ansatz equations in full generality, and for any type of Dynkin diagram. Examples are worked out to illustrate the techniques.

description: The electric dipole moment (EDM) of paramagnetic atoms is sensitive to the intrinsic EDM contribution from that of its constituent electrons and a scalar--pseudo-scalar (S-PS) electron-nucleus interactions. The electron EDM and the S-PS EDM contribution to atomic EDM scales as Z^3. Thus, the heavy paramagnetic atomic systems will exhibit large enhancement factors. However, the nature of the coupling is so small that it becomes an interest of high precision atomic experiments. In this work, we have computed the EDM enhancement factors of the ground states of Rb and Cs due to both the electron EDM and the S-PS EDM using the relativistic coupled-cluster (RCC) theory. The importance of obtaining the precise enhancement factors and the experimental results in deducing a reliable limit on the electron EDM is emphasized.

description: In der vorliegenden Arbeit wird die Ausprägung von Servant Leadership Charakteristika von Führungskräften in einem Unternehmen ausgewertet. Dazu werden die Führungskräfte der obersten vier Hierarchieebenen aller Unternehmensbereiche mittels Fragebogen, der an die Servant Leadership Survey von van Dierendonck und Nuijten angelehnt ist, befragt. Die Befragung erfolgt online in einem Unternehmens-externen Befragungssystem und in Top-Down und Bottom-Up-Sicht. Es kann gezeigt werden, dass Führungskräfte der Unternehmensbereiche Finance und Technology affiner bezüglich Servant Leadership-Charakteristika sind. Weiters zeigt die Auswertung über die unterschiedlichen Hierarchieebenen einen Verlauf der Akzeptanz von Servant Leadership-Charakteristika entlang dieser. So zeigt das Leadership-Team die höchste Akzeptanz über alle Servant Leadership-Dimensionen, Gruppenleiter:innen die geringste. Auch ist in der Schnittstelle zwischen Gruppen- und Abteilungsleitungen die Differenz zwischen wahrgenommenem und selbst-reflektiertem Servant Leadership am größten. Die vorliegende Arbeit liefert keine Indikation über die tatsächliche Effizienz der erbrachten Führung in Bezug auf Unternehmensergebnisse.
description: In the present work, the expression of servant leadership characteristics of executives in a companyis evaluated. For this purpose, the managers of the top four hierarchical levels of all company divisions are questioned using a questionnaire based on the Servant Leadership Survey by van Dierendonck and Nuijten. The survey takes place online in an external survey system and in a top-down and bottom-up view. It can be shown that executives in the corporate divisions finance and technology are more affine with regard to servant leadership characteristics. Furthermore,the evaluation shows a course of acceptance of servant leadership characteristics across the different hierarchical levels. The leadership team shows the highest level of acceptance across all servant leadership dimensions, while group leaders have the lowest level of acceptance. The difference between perceived and self-reflected servant leadership is also greatest at the interface between group and department heads. The present work does not provide any indication of the actual efficiency of the leadership provided in relation to company results.

Our simulation results based on both the bond fluctuation Monte Carlo and Molecular Dynamics methods confirm the original prediction $τ\sim N^{2ν+1}$, which scales in the same manner as the Rouse relaxation time of the chain except for a larger prefactor, and invalidates other scaling claims.

description: The magnetotransport properties of antidot lattices containing artificially designed grain boundaries have been measured. We find that the grain boundaries broaden the commensurability resonances and displace them anisotropically. These phenomena are unexpectedly weak but differ characteristically from isotropic, Gaussian disorder in the antidot positions. The observations are interpreted in terms of semiclassical trajectories which tend to localize along the grain boundaries within certain magnetic field intervals. Furthermore, our results indicate how the transport through superlattices generated by self-organizing templates may get influenced by grain boundaries.

Actually, our two-phase model of superconductivity, based on a straight generalization of the Ginzburg-Landau theory, does predict two jumps in the heat capacity as well as a double curve for the dependence of the critical temperature on an external magnetic field. Such theoretical previsions well agree with the currently available experimental data for Sr2RuO4

description: The quotient correlation is defined here as an alternative to Pearson's correlation that is more intuitive and flexible in cases where the tail behavior of data is important. It measures nonlinear dependence where the regular correlation coefficient is generally not applicable. One of its most useful features is a test statistic that has high power when testing nonlinear dependence in cases where the Fisher's $Z$-transformation test may fail to reach a right conclusion. Unlike most asymptotic test statistics, which are either normal or $χ^2$, this test statistic has a limiting gamma distribution (henceforth, the gamma test statistic). More than the common usages of correlation, the quotient correlation can easily and intuitively be adjusted to values at tails. This adjustment generates two new concepts--the tail quotient correlation and the tail independence test statistics, which are also gamma statistics. Due to the fact that there is no analogue of the correlation coefficient in extreme value theory, and there does not exist an efficient tail independence test statistic, these two new concepts may open up a new field of study. In addition, an alternative to Spearman's rank correlation, a rank based quotient correlation, is also defined. The advantages of using these new concepts are illustrated with simulated data and a real data analysis of internet traffic.

description: In this paper we investigate the properties of gauge-invariant coherent states for Loop Quantum Gravity, for the gauge group U(1). This is done by projecting the corresponding complexifier coherent states, which have been applied in numerous occasions to investigate the semiclassical limit of the kinematical sector, to the gauge-invariant Hilbert space. This being the first step to construct physical coherent states, we arrive at a set of gauge-invariant states that approximate well the gauge-invariant degrees of freedom of abelian LQG. Furthermore, these states turn out to encode explicit information about the graph topology, and show the same pleasant peakedness properties known from the gauge-variant complexifier coherent states.

description: A new density matrix and corresponding quantum kinetic equations are introduced for fermions undergoing coherent evolution either in time (coherent particle production) or in space (quantum reflection). A central element in our derivation is finding new spectral solutions for the 2-point Green's functions written in the Wigner representation, that are carrying the information of the quantum coherence. Physically observable density matrix is then defined from the bare singular 2-point function by convoluting it with the extrenous information about the state of the system. The formalism is shown to reproduce familiar results from the Dirac equation approach, like Klein problem and nonlocal reflection from a mass wall. The notion of the particle number in the presence of quantum coherence is shown to be particularily transparent in the current picture. We extend the formalism to the case of mixing fields and show how the usual flavour mixing and oscillation of neutrinos emerges again from a singular shell structure. Finally, we show how the formalism can be extended to include decohering interactions.

description: This curriculum resource is a group lab notebook to guide students through the Identification of an Unknown - an activity that usually goes on for several lab sessions. The group lab notebook stays in the classroom and it has space to leave notes for the next class meeting - especially if students know that they will be missing or if a student has missed a lab. The Identification of an Unknown is also tied to a (made-up, but realistic) case study in order to give students a concrete example.

description: In diesem Beitrag geht es um die Fotografie als künstlerische Ausdrucksform, die als Vermittlungsmedium im Exil verstanden werden kann. Neben Bildmotiven, die einen vermittelnden und aufklärenden Impetus haben, wurde das Medium auch in der fotojournalistischen Praxis und Lehre eingesetzt, fotografische Techniken und Wissen aus Europa vermittelt und gleichzeitig neue Konzepte und fotojournalistische Ansätze im Exil entworfen. Am Beispiel der Zeitschrift Picture Post in London, in der emigrierte Fotografen wie Tim Gidal arbeiteten, und der New School for Social Research in New York, in der emigrierte Fotograf*innen, Artdirektoren, Bildagenten wie Lisette Model, Marion Palfi, Alexey Brodovitch, Krut Safranszki oder Tim Gidal arbeiteten und lehrten, untersucht der Artikel die intermedialen und medialen Funktionen der Fotografie im Exil.

description: Compact binary systems with black holes are the primary sources of interferometric advanced gravitational wave detectors. Astrophysical models suggest finite possibility of binary systems with appreciable non-zero eccentricity in the dense stellar environment like globular clusters and galactic nuclei. While most of the compact binary measurements have not shown appreciable eccentricity, constrains on the eccentricity have been placed on few detected events. With increasing sensitivity of the gravitational wave detectors, the eccentric binaries are plausible sources in the gravitational wave window. Nevertheless, the challenges in the waveform modelling for high values of eccentricity constrain both the search methodologies of eccentric system as well as parameter estimation of the eccentricity. Waveform independent approaches are being investigated. In this work, we demonstrate that a new effective chirp mass $\mathcal{M}_e$ parameter can be defined which governs the dynamics of the non-spinning eccentric compact binary system. We obtain the phenomenological model of the same for low to moderate eccentricity values. One direct implication is its application in the unmodelled searches and as an another implication, we demonstrate that this model can be used to constrain the eccentricity of the non-spinning eccentric binaries in the advanced detector era in the waveform model-independent way.

A unified Abaqus implementation of the phase field fracture method using only a user material subroutine

description: We present a simple and robust implementation of the phase field fracture method in Abaqus. Unlike previous works, only a user material (UMAT) subroutine is used. This is achieved by exploiting the analogy between the phase field balance equation and heat transfer, which avoids the need for a user element mesh and enables taking advantage of Abaqus' in-built features. A unified theoretical framework and its implementation are presented, suitable for any arbitrary choice of crack density function and fracture driving force. Specifically, the framework is exemplified with the so-called AT1, AT2 and phase field-cohesive zone models (PF-CZM). Both staggered and monolithic solution schemes are handled. We demonstrate the potential and robustness of this new implementation by addressing several paradigmatic 2D and 3D boundary value problems. The numerical examples show how the current implementation can be used to reproduce numerical and experimental results from the literature, and efficiently capture advanced features such as complex crack trajectories, crack nucleation from arbitrary sites and contact problems.

description: We demonstrate a simple stacked scheme that enables absorption imaging through a hole in the surface of a grating magneto-optical trap (GMOT) chip, placed immediately below a micro-fabricated vacuum cell. The imaging scheme is capable of overcoming the reduced optical access and surface scatter that is associated with this chip-scale platform, while further permitting both trapping and imaging of the atoms from a single incident laser beam. The through-hole imaging is used to characterise the impact of the reduced optical overlap volume of the GMOT in the chip-scale cell, with an outlook to an optimised atom number in low volume systems.

The frontiers of the random walks and of their winding sectors have a Hausdorff dimension $d_H=4/3$. However, when properly defined by taking into account the inner 0-winding sectors, the frontiers of the random walks have a Hausdorff dimension $d_H\approx 1.77$.
