description: We study particle current and occupation distribution in a recently proposed model for coherent quantum transport. In this model a system connected to mesoscopic Fermi reservoirs (mesoreservoir) is driven out of equilibrium by the action of superreservoirs with prescribed temperatures and chemical potentials described by a simple dissipative mechanism with the Lindblad equation. We compare exact (numerical) results for the non-equilibrium steady state particle current with theoretical expectations based on the Landauer formula and show that the model reproduce the behavior of coherent quantum systems in the expected parameter region. We also obtain the occupation distribution on the mesoreservoir in the non-equilibrium steady state and compare them with the occupation distribution on the leads in usual description of coherent quantum transport.

description: Planets may have effects on their host stars by tidal or magnetic interaction. Such star-planet interactions are thought to enhance the activity level of the host star. However, stellar activity also affects the sensitivity of planet detection methods. Samples of planet-hosting stars which are investigated for such star-planet interactions are therefore subject to strong selection effects which need to be taken into account.

description: Direct, tunable coupling between individually assembled graphene layers is a next step towards designer two-dimensional (2D) crystal systems, with relevance for fundamental studies and technological applications. Here we describe the fabrication and characterization of large-area (> cm^2), coupled bilayer graphene on SiO2/Si substrates. Stacking two graphene films leads to direct electronic interactions between layers, where the resulting film properties are determined by the local twist angle. Polycrystalline bilayer films have a "stained-glass window" appearance explained by the emergence of a narrow absorption band in the visible spectrum that depends on twist angle. Direct measurement of layer orientation via electron diffraction, together with Raman and optical spectroscopy, confirms the persistence of clean interfaces over large areas. Finally, we demonstrate that interlayer coupling can be reversibly turned off through chemical modification, enabling optical-based chemical detection schemes. Together, these results suggest that individual 2D crystals can be individually assembled to form electronically coupled systems suitable for large-scale applications.

Creators: name: Roth, Karl Heinz
Publisher: name: DuEPublico: Duisburg-Essen Publications Online, University of Duisburg-Essen, Germany
Year: 2018

description: This essay is a critical discussion of the German revisionist historian Heinz A. Richter. Richter is a very productive writer on modern Greece, but has never, until recently, exerted substantial influence on the historiography of German-Greek relations during the 20th century, and more particularly on the historiography of the occupation of Greece in 1941–1944. This has changed in recent years, as Richter has begun to justify, from a historical viewpoint, the German government’s harsh austerity policies towards Greece. The essay presents a critical review of the methodological deficits, ideological fictions and alarming prejudices in Richter’s writing, especially with regard to his attempt to rehabilitate the collaboration between the German occupants and the Nazi faction of the Greek establishment during World War II. Part 1 of the polemic has been published in Sozial.Geschichte Online, 21 (2017).

description: Aleuropleurocelus Drews and Sampson
 Martin & Mound (2007) listed 12 described species in the genus, mostly endemic to California and the American southwestern deserts but also known from Mexico, Florida and Brazil. Dooley (2010) recently described another species, Aleuropleurocelus nevadiensis from the U.S. Several undescribed species are known from California and Nevada in the U.S.A., and Martin (2005) listed 10 undescribed species from Belize. Eight of the thirteen described species, from California and Mexico, were described in works by Sampson (1945), Drews & Sampson (1956, 1958) and Sampson & Drews (1941). Four of the twelve species were originally assigned to the European genus Tetralicia, but these have been placed now in Aleuropleurocelus. The similarities between these two genera are based primarily on the position of the true margin of the puparia (4th instar), which is rolled down and inwards, and is not visible in dorsal view. Martin (2005) discussed current ideas on the relationship between Aleuropleurocelus and Tetralicia. The new species described here was found in southern California at several desert localities, all within a few miles of each other, but probably will be found in other U.S. States and Mexico, wherever the host plant occurs. All known species of Aleuropleurocelus are melanic in the puparial stage, requiring bleaching of specimens before slide mounting for study.

description: Tau Bootis is a late F-type main sequence star orbited by a Hot Jupiter. During the last years spectropolarimetric observations led to the hypothesis that this star may host a global magnetic field that switches its polarity once per year, indicating a very short activity cycle of only one year duration. In our ongoing observational campaign, we have collected several X-ray observations with XMM-Newton and optical spectra with TRES/FLWO in Arizona to characterize tau Boo's corona and chromosphere over the course of the supposed one-year cycle. Contrary to the spectropolarimetric reconstructions, our observations do not show indications for a short activity cycle.

description: The Euler-Heisenberg effective action at the one-loop for a constant electromagnetic field is derived in Krein space quantization with Ford's idea of uctuated light-cone. In this work we present a perturbative, but convergent solution of the effective action. Without using any renormalization procedure, the result coincides with the famous renormalized Euler-Heisenberg action.

description: We study various boundary and inner regularity questions for $p(\cdot)$-(super)harmonic functions in Euclidean domains. In particular, we prove the Kellogg property and introduce a classification of boundary points for $p(\cdot)$-harmonic functions into three disjoint classes: regular, semiregular and strongly irregular points. Regular and especially semiregular points are characterized in many ways. The discussion is illustrated by examples. Along the way, we present a removability result for bounded $p(\cdot)$-harmonic functions and give some new characterizations of $W^{1, p(\cdot)}_0$ spaces. We also show that $p(\cdot)$-superharmonic functions are lower semicontinuously regularized, and characterize them in terms of lower semicontinuously regularized supersolutions.

description: We outline our techniques to characterise photospheric granulation as an astrophysical noise source. A four component parameterisation of granulation is developed that can be used to reconstruct stellar line asymmetries and radial velocity shifts due to photospheric convective motions. The four components are made up of absorption line profiles calculated for granules, magnetic intergranular lanes, non-magnetic intergranular lanes, and magnetic bright points at disc centre. These components are constructed by averaging Fe I $6302 \mathrmÅ$ magnetically sensitive absorption line profiles output from detailed radiative transport calculations of the solar photosphere. Each of the four categories adopted are based on magnetic field and continuum intensity limits determined from examining three-dimensional magnetohydrodynamic simulations with an average magnetic flux of $200 \mathrm{G}$. Using these four component line profiles we accurately reconstruct granulation profiles, produced from modelling 12 x 12 Mm$^2$ areas on the solar surface, to within $\sim \pm$ 20 cm s$^{-1}$ on a $\sim$ 100 m s$^{-1}$ granulation signal. We have also successfully reconstructed granulation profiles from a $50 \mathrm{G}$ simulation using the parameterised line profiles from the $200 \mathrm{G}$ average magnetic field simulation. This test demonstrates applicability of the characterisation to a range of magnetic stellar activity levels.

description: To a generalized tight continuous frame in a Hilbert space $\H$ indexed by a locally compact space $\Si$ endowed with a Radon measure, one associates a coorbit theory converting spaces of functions on $\Si$ in spaces of vectors comparable with $\H$. If the continuous frame is provided by the action of a suitable family of bounded operators on a fixed window, a symbolic calculus emerges, assigning operators in $\H$ to functions on $\Si$. We give some criteria of relative compactness for sets and for families of compact operators, involving tightness properties in terms of objects canonically associated to the frame. Particular attention is dedicated to a magnetic version of the pseudodifferential calculus.

On the Scaling Relations of Disk Galaxies

description: The physical background of scaling laws of disk galaxies is reviewed. The match between analytically derived and observed scaling laws is briefly discussed. Accurate modeling of the fraction of baryons that end populating a disk, and the conversion efficiency of those into stars, remains a challenging task for numerical simulations. The measurement of rotational velocity tends to be made with criteria of convenience rather than through rigorous definition. And yet, the Tully-Fisher and the disk size vs. rotational velocity relations exhibit surprisingly low scatter. Practical recipes (and costs) to optimize the quality of template relations are considered.

description: The origin of the Galactic center diffuse X-ray emission (GCDX) is still under intense investigation. In particular, the interpretation of the hot (kT ~ 7 keV) component of the GCDX, characterised by the strong Fe 6.7 keV line emission, has been contentious. If the hot component originates from a truly diffuse interstellar plasma, not a collection of unresolved point sources, such plasma cannot be gravitationally bound, and its regeneration would require a huge amount of energy. Here we show that the spatial distribution of the GCDX does NOT correlate with the number density distribution of an old stellar population traced by near-infrared light, strongly suggesting a significant contribution of the diffuse interstellar plasma. Contributions of the old stellar population to the GCDX are implied to be about 50 % and 20 % in the Nuclear stellar disk and Nuclear star cluster, respectively. For the Nuclear stellar disk, a scale height of 0.32 +- 0.02 deg is obtained for the first time from the stellar number density profiles. We also show the results of the extended near-infrared polarimetric observations in the central 3 deg * 2 deg region of our Galaxy, and confirm that the GCDX region is permeated by a large scale, toroidal magnetic field as previously claimed. Together with observed magnetic field strengths close to energy equipartition, the hot plasma could be magnetically confined, reducing the amount of energy required to sustain it.

description: We report detailed atomistic simulations combined with high-fidelity conductance calculations to probe the structural origins of conductance fluctuations in thermally evolving Au-benzene-1,4-dithiolate-Au junctions. We compare the behavior of structurally ideal junctions (electrodes with flat surfaces) to structurally realistic, experimentally representative junctions resulting from break junction simulations. The enhanced mobility of metal atoms in structurally realistic junctions results in significant changes to the magnitude and origin of the conductance fluctuations. Fluctuations are larger by a factor of 2-3 in realistic junctions compared to ideal junctions. Moreover, in junctions with highly deformed electrodes, the conductance fluctuations arise primarily from changes in the Au geometry, in contrast to results for junctions with non-deformed electrodes, where the conductance fluctuations are dominated by changes in the molecule geometry. These results provide important guidance to experimentalists developing strategies to control molecular conductance for device applications, and also to theoreticians invoking simplified structural models of junctions to predict their behavior.

description: We report the experimental demonstration of broadband negative refractive index obtained in a labyrinthine acoustic metamaterial structure. Two different approaches were employed to prove the metamaterial negative index nature: one-dimensional extractions of effective parameters from reflection and transmission measurements, and two-dimensional prism-based measurements that convincingly show the transmission angle corresponding to negative refraction. The transmission angles observed in the latter case also agree very well with the refractive index obtained in the one-dimensional measurements and numerical simulations. We expect this labyrinthine metamaterial to become the unit cell of choice for practical acoustic metamaterial devices that require broadband and significantly negative indexes of refraction.

description: We investigate the properties of features seen within superluminal sources often referred to as components. Our result indicates a fairly strong correlation of r=0.6 for quasars, r=0.4 for galaxies, and r=0.8 for BL Lac objects in our sample between component sizes and distances from the stationary core. Assumption of free adiabatic expanding plasma enabled us to constrain in general the Lorentz factor for superluminal sources. Ourestimated Lorentz factor of 7 - 17 for quasars, 6 - 13 for galaxies and 4- 9 for BL Lac objects indicate that BL Lac have the lowest range of Lorentz factor.

description: In order to study the mechanism of formation of cD galaxies we search for possible dependencies between the K-band luminosity of cDs and the parameters of their host clusters which we select to have a dominant cD galaxy, corresponding to a cluster morphology of Bautz-Morgan (BM) type I. As a comparison sample we use cD galaxies in clusters where they are not dominant, which we define here as non-BMI (NBMI) type clusters. We find that for 71 BMI clusters the absolute K-band luminosity of cDs depends on the cluster richness, but less strongly on the cluster velocity dispersion. Meanwhile, for 35 NBMI clusters the correlation between cD luminosity and cluster richness is weaker, and is absent between cD luminosity and velocity dispersion. In addition, we find that the luminosity of the cD galaxy hosted in BMI clusters tends to increase with the cD's peculiar velocity with respect to the cluster mean velocity. In contrast, for NBMI clusters the cD luminosity decreases with increasing peculiar velocity. Also, the X-ray luminosity of BMI clusters depends on the cluster velocity dispersion, while in NBMI clusters such a correlation is absent. These findings favour the cannibalism scenario for the formation of cD galaxies. We suggest that cDs in clusters of BMI type were formed and evolved preferentially in one and the same cluster. In contrast, cDs in NBMI type clusters were either originally formed in clusters that later merged with groups or clusters to form the current cluster, or are now in the process of merging.

description: Die Archäologie nutzt verschiedene Begriffe für soziale Gruppen, die bei interdisziplinären Projekten u. a. mit der Paläogenetik auch als Bezugspunkt für Vergleiche gewählt werden. Der Beitrag arbeitet den konzeptionellen Unterschied zwischen den verschiedenen Gruppenbegriffen heraus und stellt deren unterschiedliche genetische Relevanz dar. Die innerhalb der Archäologie divergierenden Modelle des Begriffs Kultur werden nach Clarke (1968) vorgestellt und gegen den Begriff Technokomplex einerseits und vor allem gegen das Begriffsbündel Stamm / Volk / Ethnos andererseits abgegrenzt. Besondere Bedeutung kommt dabei dem von Barth (1969) eingeführten Modell Ethnizität zu, das Kulturen und Ethnien voneinander unterscheidet. Die Übersicht versucht, den mit diesen Begriffen verbundenen fachimmanenten Konsens und Dissens zu umreißen. Seitens der Archäologie werden diese Gruppenbegriffe durchweg als soziale Systeme verstanden, denen nicht zwingend auch eine biologische Bedeutung zukommt.
description: Archaeology uses a variety of terms for social groups which are also used in interdisciplinary projects, including those with palaeo-genetics, as a reference point for comparisons. This contribution investigates the conceptual difference between the various group designations and presents the differences in their genetic relevance. The diverging models of the term culture within archaeology are presented according to Clarke (1968) and distinguished from the term technocomplex, on the one hand, and especially from the term ethnic group on the other. The ethnicity model introduced by Barth (1969), which distinguishes between cultural and ethnic groups, is especially significant here. The overview attempts to outline the consensus and the dissent within the discipline in relation to these terms. In archaeology these terms for groups are always understood to be social systems which do not necessarily have a biological significance as well.
Truth versus information in logic programming

description: The semantics of logic programs was originally described in terms of two-valued logic. Soon, however, it was realised that three-valued logic had some natural advantages, as it provides distinct values not only for truth and falsehood, but also for "undefined". The three-valued semantics proposed by Fitting and by Kunen are closely related to what is computed by a logic program, the third truth value being associated with non-termination. A different three-valued semantics, proposed by Naish, shared much with those of Fitting and Kunen but incorporated allowances for programmer intent, the third truth value being associated with underspecification. Naish used an (apparently) novel "arrow" operator to relate the intended meaning of left and right sides of predicate definitions. In this paper we suggest that the additional truth values of Fitting/Kunen and Naish are best viewed as duals. We use Belnap's four-valued logic, also used elsewhere by Fitting, to unify the two three-valued approaches. The truth values are arranged in a bilattice which supports the classical ordering on truth values as well as the "information ordering". We note that the "arrow" operator of Naish (and our four-valued extension) is essentially the information ordering, whereas the classical arrow denotes the truth ordering. This allows us to shed new light on many aspects of logic programming, including program analysis, type and mode systems, declarative debugging and the relationships between specifications and programs, and successive executions states of a program. This paper is to appear in Theory and Practice of Logic Programming (TPLP).

description: The Fe unresolved transition array (UTAs) produce prominent features in the 15-17?A wavelength range in the spectra of Active Galactic Nuclei (AGN). Here we present new calculations of the energies and oscillator strengths of inner- shell lines from Fe XIV, Fe XV, and Fe XVI. These are crucial ions since they are dominant at inflection points in the gas thermal stability curve, and UTA excitation followed by autoionization is an important ionization mechanism for these species. We incorporate these, and data reported in previous papers, into the plasma simulation code Cloudy. This updated physics is subsequently employed to reconsider the thermally stable phases in absorbing media in Active Galactic Nuclei. We show how the absorption profile of the Fe XIV UTA depends on density, due to the changing populations of levels within the ground configuration.

description: GRB spectra appear non-thermal, but recent observations of a few bursts with Fermi GBM have confirmed previous indications from BATSE of the presence of an underlying thermal component. Photospheric emission is indeed expected when the relativistic outflow emerging from the central engine becomes transparent to its own radiation, with a quasi-blackbody spectrum in absence of additional sub-photospheric dissipation. However, its intensity strongly depends on the acceleration mechanism - thermal or magnetic - of the flow. We aim to compute the thermal and non-thermal emissions produced by an outflow with a variable Lorentz factor, where the power injected at the origin is partially thermal (fraction epsilon_th) and partially magnetic (fraction 1-epsilon_th). The thermal emission is produced at the photosphere, and the non-thermal emission in the optically thin regime. Apart from the value of epsilon_th, we want to test how the other model parameters affect the observed ratio of the thermal to non-thermal emission. If the non-thermal emission is made by internal shocks, we self-consistently obtained the light curves and spectra of the thermal and non-thermal components for any distribution of the Lorentz factor in the flow. If the non-thermal emission results from magnetic reconnection we were unable to produce a light curve and could only compare the respective non-thermal and thermal spectra. In the different considered cases, we varied the model parameters to see when the thermal component in the light curve and/or spectrum is likely to show up or, on the contrary, to be hidden. We finally compared our results to the proposed evidence for the presence of a thermal component in GRB spectra. Focussing on GRB 090902B and GRB 10072B, we showed how these observations can be used to constrain the nature and acceleration mechanism of GRB outflows.

title: Miniature objects in the hands of women – on the so-called Mithrassymbole

description: Bei den sogenannten Mithrassymbolen handelt es sich um Buntmetallminiaturen, die in römischen Frauengräbern vorwiegend im Kölner Raum gefunden werden. Diese sind in der Forschung sehr unterschiedlich religiös oder profan interpretiert worden. Die bisherigen Deutungen bleiben jedoch unbefriedigend. Ein Vergleich der kleinen Plastiken mit anderen ungewöhnlichen Fundgattungen aus Kästchen von Frauengräbern des Kölner Raums zeigt, dass sie offenbar als Sammelgegenstände gesehen werden können. Das umfangreichste Ensemble aus Köln-Rodenkirchen deckt modellhaft weite Teile der Ausstattung eines Landgutes ab, die anderen Fundkomplexe kleinere Ausschnitte. Frauen und Mädchen haben somit dekorative Teile einer Hofausstattung »en miniature« gesammelt und als Grabbeigabe erhalten, die eine Selbstreflexion mit Blick auf das Ideal des Landlebens ermöglichten. Natürlich lässt sich nicht ausschließen, dass sie
diese darüber hinaus als Amulette gesehen haben, zwingend ist dies aber nicht. Da die Bezeichnung »Mithras symbole« zwar griffig, aber ebenso sachlich unzutreffend wie irreführend ist, sollten die Objekte besser nur noch mit neutraleren Begriffen wie hier als Miniaturen angesprochen werden.
description: The so-called Mithrassymbole are small bronze objects found in Roman female burials mostly in the area of Cologne. The interpretations of these artefacts, though covering a wide range of religious and profane ideas, remain unsatisfactory. A comparison with some other unusual female grave-goods in the area leads to the conclusion that they can be considered as some kind of collector’s items. The biggest set from Cologne-Rodenkirchen covers large parts of the equipment of a Roman farmhouse, others only smaller components. Therefore, women and girls seem to have collected the items for the purpose of reflecting the Roman ideal of farming, and were buried with them. Other than that, it is possible, but as yet without evidence, that they have been considered amulets. In future neutral terms should be used instead of »Mithrassymbole«.

description: We propose a joint optimal power allocation and sensing threshold selection for capacity maximization at the secondary user (SU) in spectrum sharing (SS) cognitive radio networks (CRNs). Hence, both optimal power allocation (OPA) and spectrum sensing (SpSe) is considered in the SS CRNs model. The obtained results show that such a joint optimal selection improves the performance of the SU by maximizing its capacity.

description: The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that are highly non-potential - that is, they have been stressed above their lowest-energy state. This non-potential component of the surface field is neglected by current stellar wind models. The aim of this paper is to determine its effect on the coronal structure and wind. We use Zeeman-Doppler surface magnetograms of two stars - one with an almost potential, one with a non-potential surface field - to extrapolate a static model of the coronal structure for each star. We find that the stresses are carried almost exclusively in a band of uni-directional azimuthal field that is confined to mid-latitudes. Using this static solution as an initial state for an MHD wind model, we then find that the final state is determined primarily by the potential component of the surface magnetic field. The band of azimuthal field must be confined close to the stellar surface as it is not compatible with a steady-state wind. By artificially increasing the stellar rotation rate we demonstrate that the observed azimuthal fields can not be produced by the action of the wind but must be due to processes at or below the stellar surface. We conclude that the background winds of solar-like stars are largely unaffected by these highly-stressed surface fields. Nonetheless, the increased flare activity and associated coronal mass ejections that may be expected to accompany such highly-stressed fields may have a significant impact on any surrounding planets.

INVESTIGATION OF COMBINATORIAL OPTIMIZATION TECHNIQUES FOR SOLVING NP-HARD PROBLEMS

description: Finding the optimum answer from a limited number of options is the goal of a class of computing issues known as combinatorial optimisation problems. This category includes a lot of real-world issues like the travelling salesman dilemma, the knapsack issue, and the graph colouring issue. These issues are NP-hard, which means that applying precise techniques to identify the best answer for a big instance is computationally impossible. Met heuristic methods like simulated annealing, ant colony optimisation, and genetic algorithms have attracted a lot of attention because of their ability to explore vast solution spaces while avoiding local optima. These algorithms use randomised search methods that resemble natural processes to iteratively improve the solutions. They have been successfully used to many different fields and have demonstrated promising results when tackling NP-hard problems. By giving polynomial-time algorithms that can ensure results within a specific factor of the best solution, approximation algorithms provide a distinct viewpoint. These algorithms forgo optimality in favour of efficiency, and the calibre of the discovered solutions is used to gauge how well they function. When creating approximation algorithms, methods like greedy algorithms, local search, and randomization are essential. This research on combinatorial optimisation methods for NP-hard issues aids in the creation of effective algorithms that can take on complex optimisation problems in the real world. Researchers can learn about the benefits and drawbacks of various approaches by examining and contrasting them, as well as by selecting the strategies that are best suited for particular problem domains.
title: Caching and retooling in Potočka zijalka (Slovenia). Implications for Late Aurignacian land use strategies

description: Die hochalpine Höhlenfundstelle Potočka zijalka in Slowenien ist schon lange für ihre große Sammlung spätaurignacienzeitlicher Knochenspitzen mit massiver Basis (Typ Lautsch, Mladeč oder Olševa) bekannt. Sowohl die Funktion als auch die kulturelle Zuweisung des Fundortes wurden nach den ersten offiziellen Grabungen im Jahr 1928 immer wieder diskutiert. Die vorliegende Studie beschreibt zunächst die unterschiedlichen Bruchmuster der Knochenspitzen aus Potočka zijalka. Die daran anschließende räumliche Analyse legt nahe, dass im vorderen Teil der Höhle primär die Reparatur von Waffen erfolgte, während Knochenspitzen im hinteren Teil vor allem bevorratet wurden. Ein Abgleich mit anderen ost- und mitteleuropäischen Fundplätzen des älteren und jüngeren Aurignacien zeigt, dass vergleichbare Verhältnisse immer wieder zu erkennen, aber auch nur kurzzeitig genutzte Höhlenfundstellen vorhanden sind. Anhand der Nutzungsweise der Knochenspitzen und der Organisation mancher Fundorte lässt sich nachweisen, dass die Hochgebirgsregionen der östlichen Alpen durch den frühen modernen Menschen viel regelmäßiger aufgesucht wurden als bisher zumeist erwartet.
description: The high alpine cave of Potočka zijalka in Slovenia is renowned for a large collection of Late Aurignacian bone points with a massive base. The function and cultural association of the site have been discussed since the first official excavations in 1928. This paper deals with the breakage patterns of the bone points. The study indicates that the front of the cave was mainly used for retooling activities whereas the rear part of the cave was used for implement caching. The comparison with other cave sites with bone points in Central and Eastern Europe shows a clear-cut pattern of assemblage variability with caches, retooling loci and small field processing sites in the Early as well as Late Aurignacian. The organization of the projectile technology suggests that the exploitation of mountainous regions in the Eastern Alps during the Early Upper Palaeolithic was more common than previously acknowledged.
