description: In diesem Artikel wird das Ergebnis einer systematischen Oberflächenprospektion in Ondratice I/Želeč (Mittelmähren) diskutiert. Die Steinartefaktaufsammlung ist sowohl durch zahlreiche Stücke des Levalloiskonzeptes (Kerne, Spitzen, Abschläge, Klingen) und flächenretuschierte Objekte (Blattspitzen, Jerzmanowicespitzen, Schaber) als auch durch steilkantenretuschierte Artefakte (Kratzer, retuschierte Klingen) charakterisiert. Diese verschiedenen Gerätetypen und Grundformen bzw. Abfallprodukte sind generell typisch für drei unterschiedliche mitteleuropäische Technokomplexe am Übergang vom Mittel- zum Jungpaläolithikum – nämlich Bohunicien, Szeletien und Aurignacien. Die Mischung charakteristischer Steinartefakte dieser drei Technokomplexe in Ondratice I/Želeč kann möglicherweise damit erklärt werden, dass sie auf der Oberfläche gefunden wurden, und somit ein vermischtes Inventar repräsentieren. Jedoch werden auch aus anderen Teilen Mährens derartige Oberflächeninventare beschrieben. Für ein besseres Verständnis und für eine Datierung solcher Steinartefaktvergesellschaftungen ist letztlich die Ausgrabung eines stratifizierten Platzes notwendig.
description: The Ondratice I/Želeč site represents one of the most important Early Upper Palaeolithic localities in central Moravia. This site has been studied since the late 19th century and the surveys continue up to the present. A recently obtained lithic assemblage (collected during 2009-2011) is characterised by the Levallois industry (cores, points, flakes, blades), together with flat retouched artefacts (leaf and Jerzmanowice points, side-scrapers) and steeply retouched objects (end-scrapers, retouched blades). These tools are typical of three different cultures in Central Europe – the Bohunician, Szeletian and Aurignacian. The mixture of finds characteristic of three different Early Upper Palaeolithic cultures may relate to the surface origin of the assemblage. However, similar assemblages are described in different parts of Moravia. In order to understand and date these lithics better it will be necessary to excavate a stratified site.

description: Young close binaries clear central cavities in their surrounding circumbinary disk from which the stars can still accrete material. This process takes place within the very first astronomical units, and is still not well constrained as the observational evidence has been gathered, until now, only by means of spectroscopy. The young object HD200775 (MWC361) is a massive spectroscopic binary (separation of ~15.9mas, ~5.0~AU), with uncertain classification (early/late Be), that shows a strong and variable Halpha emission. We aim to study the mechanisms that produce the Halpha line at the AU-scale. Combining the radial velocity measurements and astrometric data available in the literature, we determined new orbital parameters. With the VEGA instrument on the CHARA array, we spatially and spectrally resolved the Halpha emission of HD200775, at low and medium spectral resolutions (R~1600 and 5000) over a full orbital period (~3.6 years). We observe that the Halpha equivalent width varies with the orbital phase, and increases close to periastron, as expected from theoretical models that predict an increase of the mass transfer from the circumbinary disk to the primary disk. In addition, using spectral visibilities and differential phases, we find marginal variations of the typical extent of the Halpha emission (at 1 to 2-sigma level) and location (at 1 to 5-sigma level). The spatial extent of the Halpha emission, as probed by a Gaussian FWHM, is minimum at the ascending node (0.67+/-0.20 mas, i.e., 0.22+/-0.06 AU), and more than doubles at periastron. In addition, the Gaussian photocenter is slightly displaced in the direction opposite to the secondary, ruling out the scenario in which all or most of the Halpha emission is due to accretion onto the secondary. These findings, together with the wide Halpha line profile, may be due to a non-spherical wind enhanced at periastron.

description: It is well known that asteroseismology is the unique technique permitting the study of the internal structure of pulsating stars using their pulsational frequencies, which is per se very important. It acquires an additional value when the star turns out to be a planet host. In this case, the asteroseismic study output may be a very important input for the study of the planetary system. With this in mind, we use the large time-span of the Kepler public data obtained for the star system HAT-P-7, first to perform an asteroseismic study of the pulsating star using Time-Dependent-Convection (TDC) models. Secondly, we make a revision of the planet properties in the light of the asteroseismic study.

description: I summarize some constraints on the physics of neutron stars arising from X-ray observations of the surfaces of neutron stars, focusing on using models of low-magnetic-field neutron star atmospheres to interpret their X-ray spectra. I discuss observations of spectral lines, pulsation profiles, X-ray bursts, radius measurements of transiently accreting neutron stars in quiescence, crust and core cooling measurements of transiently accreting neutron stars, and cooling of young neutron stars. These observations have constrained the neutron star mass and radius (and thus the internal composition, and dense matter equation of state), the superfluidity and neutrino emissivity properties of the core, and the composition and superfluid state of the crust.

description: The mixed-valent multiferroic compound CaMn7O12 is studied for its magnetic and electric properties. The compound undergoes magnetic ordering below 90 K with a helimagnetic structure followed by a low temperature magnetic anomaly observed around 43 K. The present study shows that the magnetic anomaly at 43 K is associated with thermal hysteresis indicating first order nature of the transition. The compound also shows field-cooled magnetic memory and relaxation below 43 K, although no zero-field-cooled memory is present. Clear magnetic hysteresis loop is present in the magnetization versus field measurements signifying the presence of some ferromagnetic clusters in the system. We doped trivalent La at the cite of divalent Ca expecting to enhance the fraction of Mn$^{3+}$ ions. The La doped samples show reduced magnetization, although the temperatures associated with the magnetic anomalies remain almost unaltered. Interestingly, the spontaneous electrical polarization below 90 K increases drastically on La substitution. We propose that the ground state of the pure as well as the La doped compositions contain isolated superparamagnetic like clusters, which can give rise to metastability in the form of field-cooled memory and relaxation. The ground state is not certainly spin glass type as it is evident from the absence of zero-field-cooled memory and frequency shift in the ac suceptibility measurements.

description: The band structures and optical properties of monoclinic HfO2 are investigated by the local density approximation (LDA)+U approach. With the on-site Coulomb interaction being introduced to 5d orbitals of Hf atom and 2p orbitals of O atom, the experimental band gap is reproduced. The imaginary part of the complex dielectric function shows a small shoulder at the edge of the band gap, coinciding with the experiments. This intrinsic property of crystallized monoclinic HfO2, which is absent in both the tetragonal phase and cubic phase, can be understood as a consequence of the reconstruction of the electronic states near the band edge following the adjustment of the crystal structure. The existence of a similar shoulder-like-structure in the monoclinic phase of ZrO2 is predicted.

Creators: name: Peglau, Andreas
Publisher: name: DuEPublico: Duisburg-Essen Publications Online, University of Duisburg-Essen, Germany

description: The article begins by acknowledging the pioneering achievements, with regard to the study of right-wing extremism, of the psychoanalysts and social scientists Wilhelm Reich (1897–1957) and Erich Fromm (1900–1980). These achievements, largely unknown or ignored today, are related to their historical context. The main section of the article then engages with the hypothesis that the authoritarian character is “becoming obsolete.” This hypothesis, derived from the findings of the Leipzig University studies on Germany’s political “center,” is being defended today by the sociologist and social psychologist Oliver Decker. The article demonstrates that the arguments in favor of such obsolescence are questionable, and that it would be dangerous to underestimate the significant influence still exerted by these massively evident character structures, which are constantly being reproduced by alienated socialization and the capitalist social system.

description: The propagation of a virtual quark in a thermal medium is considered. The non-perturbative jet transport coefficient $\hat{q}$ is estimated in quark less SU(2) lattice gauge theory. The light like correlator which defines $\hat{q}$, defined in the regime where the jet has small virtuality compared to its energy, is analytically related to a series of local operators in the deep Euclidean region, where the jet's virtuality is of the same order as its energy. It is demonstrated that in this region, for temperatures in the range of T=400-600 MeV, and for jet energies above 20 GeV, the leading term in the series is dominant over the next-to-leading term and thus yields an estimate of the value of $\hat{q}$. In these proceedings we discuss the details of the numerical calculation.

description: A full implementation of the Boltzmann-Langevin equation for fermionic systems is introduced in a transport model for dissipative collisions among heavy nuclei. Fluctuations are injected in phase space and not, like in more conventional approaches, as a projection on suitable subspaces. The advantage of this model is to be specifically adapted to describe processes characterised by instabilities, like the formation of fragments from a hot nuclear system, and by dissipation, like the transparency in nucleus-nucleus collisions.

description: The classical Faber-Krahn inequality asserts that balls (uniquely) minimize the first eigenvalue of the Dirichlet-Laplacian among sets with given volume. In this paper we prove a sharp quantitative enhancement of this result, thus confirming a conjecture by Nadirashvili and Bhattacharya-Weitsman. More generally, the result applies to every optimal Poincaré-Sobolev constant for the embeddings $W^{1,2}_0(Ω)\hookrightarrow L^q(Ω)$.

description: We consider the problem of the exact computation of the correlation functions of the eight-vertex solid-on-solid model by means of the algebraic Bethe Ansatz. We compute the scalar product between a Bethe eigenstate and an arbitrary state of Bethe type and show that, in the cyclic case, it can be formulated as a single determinant of usual functions. It allows us to obtain determinant representations for finite-size form factors. By summing up over the form factors, we also give a multiple integral representation for a generating function of the two-point function.

The nanowires are suspended 15\,nm above a local gate electrode. The charge density in the nanowires can be controlled by a small change in the gate voltage. For large negative gate voltages, the number of conducting channels is reduced gradually and we observe a stepwise decrease of both conductance and critical current before the conductance vanishes completely.

description: In digital transformation, incumbents are pressured to exploit their core business and simultaneously explore opportunities for digital innovation. When pursuing ambidexterity, organizations establish digital innovation units (DIUs) dedicated to digital innovation. Due to the novelty of the phenomenon, prior studies targeted DIUs' design, objectives, and challenges. However, their value lies in reintegrating digital innovations back into the operational organization for use and commercialization, which has been neglected so far. Thus, we analyze the reintegration based on a single-embedded case study of four heterogeneous DIUs. We identify three phases of reintegration activities and trace differences to the contextual factors: innovation orientation, number of involved entities, and ownership. Our contribution is twofold. First, we shed light on the reintegration of DIUs' innovation outcomes for the first time. Second, we extend research on digital innovation and ambidexterity by outlining drivers and inhibitors of reintegration, enhancing our understanding of how organizations can exploit exploration.

description: Maser transitions are commonly observed in media exhibiting a large range of densities and temperatures. They can be used to obtain information on the dynamics and physical conditions of the observed regions. In order to obtain reliable constraints on the physical conditions prevailing in the masing regions, it is necessary to model the excitation mechanisms of the energy levels of the observed molecules. We present a numerical method that enables us to obtain self-consistent solutions for both the statistical equilibrium and radiative transfer equations. Using the standard maser theory, the method of Short Characteristics is extended to obtain the solution of the integro-differential radiative transfer equation, appropriate to the case of intense masing lines. We have applied our method to the maser lines of the H2O molecule and we compare with the results obtained with a less accurate approach. In the regime of large maser opacities we find large differences in the intensity of the maser lines that could be as high as several orders of magnitude. The comparison between the two methods shows, however, that the effect on the thermal lines is modest. Finally, the effect introduced by rate coefficients on the prediction of H2O masing lines and opacities is discussed, making use of various sets of rate coefficients involving He, o-H2 and p-H2. We find that the masing nature of a line is not affected by the selected collisional rates. However, from one set to the other the modelled line opacities and intensities can vary by up to a factor ~2 and ~10 respectively.

description: We perform scanning gate experiments on ballistic constrictions in the presence of small perpendicular magnetic fields. The constrictions form the entrance and exit of a circular gate-defined ballistic stadium. Close to constrictions we observe sets of regular fringes creating a checker board pattern. Inside the stadium conductance fluctuations governed by chaotic dynamics of electrons are visible. The checker board pattern allows us to determine the number of transmitted modes in the constrictions forming between the tip-induced potential and gate-defined geometry. Spatial investigation of the fringe pattern in a perpendicular magnetic field shows a transition from electrostatic to magnetic depopulation of magnetoelectric subbands. Classical and quantum simulations agree well with different aspects of our observations.

Investigating the Role of FGL2 in Tumour Progression and Surgical Stress-Induced Immunosuppression

description: Fibrinogen-like protein 2 (FGL2) expression is associated with tumour progression and poor survival in a number of different cancers. In these cancers, FGL2 promotes tumour progression via an immunosuppression-mediated mechanism or by promoting angiogenesis. Querying single-cell RNA sequencing (scRNA-seq) human cancer data shows FGL2 is produced by immune and stromal cells in the tumour microenvironment (TME), while cancer cells have minimal expression of FGL2. We therefore studied the role of FGL2 produced by cells in the TME in tumour progression in two models of cancer in which the role of FGL2 has not been previously studied: epithelial ovarian cancer (EOC) and melanoma. EOC is the most lethal gynecologic cancer with an imperative need for new treatments. Before testing novel immunotherapies, we first characterized the TME of six syngeneic ovarian cancer models. ID8-p53-/- and ID8-C3 tumours were most highly infiltrated by T cells, whereas STOSE and MOE-PTEN/KRAS tumours were primarily infiltrated by tumour associated macrophages and were unique in MHC class I and II expression. This panel of well-defined murine EOC models can serve as a valuable resource for studies that aim to test immunotherapies. We next studied the role of FGL2 in tumour progression in melanoma and ovarian cancer models. Using wild-type and FGL2 knockout mice, we found that absence of FGL2 led to a more activated TME, including activated dendritic cells (DCs - CD86+, CD40+) and T cells (CD25+, TIGIT+), as well as demonstrating for the first time that the absence of FGL2 led to more activated Natural Killer (NK) cells (DNAM-1, NKG2D) in the TME. The absence of FGL2 prolonged survival in the B16F10 model of melanoma, and synergized with oncolytic virus to prolong survival in the ID8-p53-/-Brca2-/- model of ovarian cancer.

In this paper we show that for relativistic fluids an electric field generates a heat flux even in the single component case. In the non-relativistic limit the effect vanishes and Fourier's law is recovered. This result is novel and may have applications in the transport properties of very hot plasmas.

description: The Moors have been regarded by Graeco-Roman authors with a mixture of ambivalence and admiration. From the highly positive characterizations of Moorish giants like Masinissa (238-148 BCE) whose achievements the Romans lauded, to figures like Jugurtha (fl. 118-104 BCE) and Gildo (fl. 396-398 CE) whose hostilities with Rome earned them both scorn and ridicule, Moorish figures loom large in the pages of ancient historians from Herodotus to Procopius. This thesis examines the shifting portrayal of Moors from their earliest literary depictions in Greek literary sources to the late Roman literary portrayals of the sixth century CE. It argues that certain stereotypes regarding Moors, a problematic term that will be discussed in greater detail, continued relatively unchanged in Graeco-Roman authors, and that this was highly dependent on genre, political context, and intertextuality. It further argues that negative vs. positive portrayals of Moors can be understood better via an examination of the context of an author on an individual level, where political background was key to an historian’s evaluation of a certain Moorish figure or of Moors in general.

description: In this paper, we study the robustness of interdependent networks, in which the state of one network depends on the state of the other network and vice versa. In particular, we focus on the interdependency between the power grid and communication networks, where the grid depends on communications for its control, and the communication network depends on the grid for power. A real-world example is the Italian blackout of 2003, when a small failure in the power grid cascaded between the two networks and led to a massive blackout. In this paper, we study the minimum number of node failures needed to cause total blackout (i.e., all nodes in both networks to fail). In the case of unidirectional interdependency between the networks we show that the problem is NP-hard, and develop heuristics to find a near-optimal solution. On the other hand, we show that in the case of bidirectional interdependency this problem can be solved in polynomial time. We believe that this new interdependency model gives rise to important, yet unexplored, robust network design problems for interdependent networked infrastructures.

description: Neutrinoless double beta decay, if observed, could distinguish whether neutrino is a Dirac or a Majorana particle, and it could be used to determine the absolute scale of the neutrino masses. $^{136}$Xe is one of the most promising candidates for observing this rare event. However, until recently there were no positive result for the allowed and less rare two-neutrino double beta decay mode. The small nuclear matrix element associated with the small half-life represents a challenge for nuclear structure models used for its calculation. We report a new shell-model analysis of the two-neutrino double beta decay of $^{136}$Xe, which takes into account all relevant nuclear orbitals necessary to fully describe the associated Gamow-Teller strength. We further use the new model to analyze the main contributions to the neutrinoless double beta decay half-life, and show that they are also diminished.

description: We investigate the large scale metallicity distribution in the Galactic bulge, using a large spatial coverage, in order to constrain the bulge formation scenario. We use the VISTA variables in the Via Lactea (VVV) survey data and 2MASS photometry, covering 320 sqdeg of the Galactic bulge, to derive photometric metallicities by interpolating of the (J-Ks)0 colors of individual Red Giant Branch stars based on a set of globular cluster ridge lines. We then use this information to construct the first global metallicity map of the bulge with a resolution of 30'x45'. The metallicity map of the bulge revealed a clear vertical metallicity gradient of ~0.04 dex/deg (~0.28 dex/kpc), with metal-rich stars ([Fe/H]~0) dominating the inner bulge in regions closer to the galactic plane (|b|<5). At larger scale heights, the mean metallicity of the bulge population becomes significantly more metal-poor. This fits in the scenario of a boxy-bulge originated from the vertical inestability of the Galactic bar, formed early via secular evolution of a two component stellar disk. Older, metal-poor stars dominate at higher scale heights due to the non-mixed orbits from the originally hotter thick disk stars.

description: Combining low cost wireless EEG sensors with smartphones offers novel opportunities for mobile brain imaging in an everyday context. We present a framework for building multi-platform, portable EEG applications with real-time 3D source reconstruction. The system - Smartphone Brain Scanner - combines an off-the-shelf neuroheadset or EEG cap with a smartphone or tablet, and as such represents the first fully mobile system for real-time 3D EEG imaging. We discuss the benefits and challenges of a fully portable system, including technical limitations as well as real-time reconstruction of 3D images of brain activity. We present examples of the brain activity captured in a simple experiment involving imagined finger tapping, showing that the acquired signal in a relevant brain region is similar to that obtained with standard EEG lab equipment. Although the quality of the signal in a mobile solution using a off-the-shelf consumer neuroheadset is lower compared to that obtained using high density standard EEG equipment, we propose that mobile application development may offset the disadvantages and provide completely new opportunities for neuroimaging in natural settings.

description: The majority of dynamical studies in power systems focus on the high voltage transmission grids where models consider large generators interacting with crude aggregations of individual small loads. However, new phenomena have been observed indicating that the spatial distribution of collective, nonlinear contribution of these small loads in the low-voltage distribution grid is crucial to outcome of these dynamical transients. To elucidate the phenomenon, we study the dynamics of voltage and power flows in a spatially-extended distribution feeder (circuit) connecting many asynchronous induction motors and discover that this relatively simple 1+1 (space+time) dimensional system exhibits a plethora of nontrivial spatio-temporal effects, some of which may be dangerous for power system stability. Long-range motor-motor interactions mediated by circuit voltage and electrical power flows result in coexistence and segregation of spatially-extended phases defined by individual motor states--a "normal" state where the motors' mechanical (rotation) frequency is slightly smaller than the nominal frequency of the basic AC flows and a "stalled" state where the mechanical frequency is small. Transitions between the two states can be initiated by a perturbation of the voltage or base frequency at the head of the distribution feeder. Such behavior is typical of first-order phase transitions in physics, and this 1+1 dimensional model shows many other properties of a first-order phase transition with the spatial distribution of the motors' mechanical frequency playing the role of the order parameter. In particular we observe (a) propagation of the phase-transition front with the constant speed very long feeders; and (b) hysteresis in transitions between the normal and stalled (or partially stalled) phases.

description: This paper introduces a new dynamic neighborhood network for particle swarm optimization. In the proposed Clubs-based Particle Swarm Optimization (C-PSO) algorithm, each particle initially joins a default number of what we call 'clubs'. Each particle is affected by its own experience and the experience of the best performing member of the clubs it is a member of. Clubs membership is dynamic, where the worst performing particles socialize more by joining more clubs to learn from other particles and the best performing particles are made to socialize less by leaving clubs to reduce their strong influence on other members. Particles return gradually to default membership level when they stop showing extreme performance. Inertia weights of swarm members are made random within a predefined range. This proposed dynamic neighborhood algorithm is compared with other two algorithms having static neighborhood topologies on a set of classic benchmark problems. The results showed superior performance for C-PSO regarding escaping local optima and convergence speed.

description: Der folgende Beitrag entstand als Vorstudie zu einem größeren Forschungsvorhaben zur Zerschlagung der jüdischen Wirtschaftsunternehmen durch die deutsche Besatzungsmacht in Belgien in den Jahren 1942–1944, das die Verfasser zurzeit gemeinsam durchführen. Dabei sind wir von zwei Besonderheiten ausgegangen, die die „Arisierung“ in Belgien von der in Deutschland unterschieden: Zum einen waren die damals in Belgien lebenden Juden zum allergrößten Teil Immigranten aus Osteuropa. Zum anderen führte die von den Deutschen angeordnete „Arisierung“ der belgischen Wirtschaft nur in wenigen Fällen zu Firmenübernahmen, vielmehr zielte sie auf die Liquidation nahezu sämtlicher Klein- und Mittelbetriebe jüdischer Inhaber. So stellte sich uns zunächst die Frage nach der Entstehung und dem Charakter dieser migrantisch geprägten Ökonomie. Der vorliegende Aufsatz versucht, diese Frage mithilfe statistisch aufbereiteter Massendaten, aber auch durch Heranziehung vieler individueller Fallgeschichten zu beantworten.
description: The “Aryanization” of the Belgian economy ordered by the German occupants aimed at the liquidation of virtually all small and medium-sized businesses owned by Jews. Most of these business owners had immigrated to Belgium from Eastern Europe. The articles deals with the genesis of this immigrant economy, presenting new findings on Jewish immigration to Belgium and examining the structure of Jewish businesses, as well as their distribution in Antwerp and Brussels. Statistically processed mass data serve as the basis for this, though individual case histories are also presented. The businesses of Jewish immigrants were mostly small family businesses and of an artisanal or proto-industrial nature, specializing on a few branches of trade and unable to secure for their owners more than a precarious existence. The article, which is being published in two parts, concludes with quotations from petitions business owners addressed to the German military administration in an effort to ward off the elimination of their livelihoods.

description: We report on the detection of a hot subdwarf component in the Be binary system, 59 Cygni. The spectral signature is found in cross-correlation functions of photospheric model spectra with far-ultraviolet spectra obtained by the International Ultraviolet Explorer Satellite, and we used radial velocities from the cross-correlation functions to determine a double-lined spectroscopic orbit. The individual spectra of the binary components were extracted using a Doppler tomography algorithm. The flux of the system is dominated by the rapidly rotating Be star. However, the subdwarf contributes approximately 4% of the UV flux, and its spectrum bears a strong resemblance to that of the hot sdO star BD +75 325. Based upon the appearance of the UV spectrum and the orbital elements, we present estimates for the stellar masses, radii, and temperatures. The presence of the hot companion causes excess emission from the outer part of the Be disk facing the companion. We present a set of red spectra that show the orbital phase variations of the He I 6678 emission formed in the heated region of the disk, which probably occurs near the disk outer boundary. 59 Cygni, FY Canis Majoris, and phi Persei comprise the known set of Be binaries with detected hot evolved companions, which are the stripped down remains of mass transfer. Their properties demonstrate that some fraction of Be stars were spun up through angular momentum transfer by Roche lobe overflow.
