description: Der verantwortungsbewusste Umgang mit alt- und nachbergbaulichen Strukturen umfasst den Aufbau und die Entwicklung eines integrierten Risikomanagementsystems. Daher ist es wichtig, aktuelle Informationen über die bergbaulichen Elemente, ihren Zustand und mögliche Auswirkungen auf die Tagesoberfläche mittels verschiedener Monitoringmethoden zu ermitteln. Die Überwachung mittels Methoden der satellitengestützten Erdbeobachtung generiert Sensordaten, die mit in-situ Datensätzen zu validieren sind. Im Projekt "Gemeinsames Monitoring im Altbergbau" wurden für die Altgesellschaften des Steinkohlenbergbaus im südlichen Ruhrgebiet in einer ersten Projektphase die Elemente des Alt- und Nachbergbaus, die möglichen Ereignisse und die Parameter zur Detektion und die Möglichkeit der Messung der Ereignisse integriert betrachtet. In der aktuell laufenden zweiten Projektphase werden Radardaten des EU-Copernicus Programmes genutzt, um Bodenbewegungen mittels radarinterferometrischer PSI- und DSI-Methoden zu detektieren. Hierbei kommen innovative Methoden zur frühzeitigen Integration der Oberflächennutzung zur Anwendung, um so eine bessere Klassifizierung und Signifikanzanalyse der Bodenbewegung zu erreichen. Der Auswerteprozess wird zusätzlich mit alt- und nachbergbaulichen in-situ Daten angereichert. Das Projekt "Gemeinsames Monitoring im Altbergbau" bietet somit zukünftig die Möglichkeit alt- und nachbergbauliche Fragestellungen im Rahmen eines integrierten Risikomanagementsystems zu beantworten.

description: We report the low-temperature coexistence in NdFe3(BO3)4 of an incommensurate magnetic phase with a strained commensurate magnetic phase that is primarily at the surface of the crystal. Increasing the temperature or magnetic field decreases the incommensurability and stabilizes the commensurate magnetic phase above Tic ~14 K or Hic = 0.9 T. A comparison to published studies indicates the onset of longitudinal magnetostriction and electric polarization at the magnetic-field-induced transition, which may arise due to a basal plane spin-flop and canting of the moments along the field direction.

description: Im Rahmen der Bearbeitung alt- und nachbergbaulicher Prozesse ist es wichtig umfassende und integrierte Kenntnisse über die Lagerstätte, das Deckgebirge, die Deckschichten und die Tagesoberfläche eines jeden Bergbaustandortes zu haben, umso die langfristige Integrität nachweisen zu können. Hierbei ist es wichtig gesamtheitliche und voll digitale Ansätze zu nutzen und diese auch rückwirkend auf den Bergbauzyklus und die damit verbundenen Datensätze anzuwenden. Nur durch die Arbeit in der vierten Dimension sind Aussagen für zukünftige Programme zum alt- und nachbergbaulichen Geomonitoring eines Standortes zu treffen. Diese Komplexität gilt es in der Lehre abzubilden.

description: Using the ground potential energy surface[M. Ayouz \textit{et\, al}. J. Chem Phys \textbf{132} 194309 (2010)] of the H$_3^-$ molecule, we have determined the energies and widths of the complex resonant levels of H$_3^-$ located up to 4000 cm$^{-1}$ above the dissociation limit H$^-$+H$_2(v_d=0,j_d=0)$. Bound and resonant levels of the H$_2$D$^-$ and D$_2$H$^-$ isotopologues have been also characterized within the same energy range. The method combines the hyperspherical adiabatic approach, slow variable discretization method, and complex absorbing potential. These results represent the first step for modeling the dynamics of the associated diatom-negative ion collision at low energy involving rotational quenching of the diatom and reactive nucleus exchange via weak tunneling effect through the potential barrier of the potential energy surface.

description: We present results from deep imaging linear and circular polarimetry of the massive star-forming region NGC 6334- V. These observations show high degrees of circular polarization (CP), as much as 22 % in the Ks band, in the infrared nebula associated with the outflow. The CP has an asymmetric positive/negative pattern and is very extended (~80" or 0.65 pc). Both the high CP and its extended size are larger than those seen in the Orion CP region. Three-dimensional Monte Carlo light-scattering models are used to show that the high CP may be produced by scattering from the infrared nebula followed by dichroic extinction by an optically thick foreground cloud containing aligned dust grains. Our results show not only the magnetic field orientation of around young stellar objects but also the structure of circumstellar matter such as outflow regions and their parent molecular cloud along the line of sight. The detection of the large and extended CP in this source and the Orion nebula may imply the CP origin of the biological homochirality on Earth.

description: We present a new massively parallel code for N-body and cosmological hydrodynamical simulations of modified gravity models. The code employs a multigrid-accelerated Newton-Gauss-Seidel relaxation solver on an adaptive mesh to efficiently solve for perturbations in the scalar degree of freedom of the modified gravity model. As this new algorithm is implemented as a module for the P-Gadget3 code, it can at the same time follow the baryonic physics included in P-Gadget3, such as hydrodynamics, radiative cooling and star formation. We demonstrate that the code works reliably by applying it to simple test problems that can be solved analytically, as well as by comparing cosmological simulations to results from the literature. Using the new code, we perform the first non-radiative and radiative cosmological hydrodynamical simulations of an f(R)-gravity model. We also discuss the impact of AGN feedback on the matter power spectrum, as well as degeneracies between the influence of baryonic processes and modifications of gravity.

description: Nevanlinna showed that two non-constant meromorphic functions on $\mathbb C$ must be linked by a Möbius transformation if they have the same inverse images counted with multiplicities for four distinct values. After that this results is generalized by Gundersen to the case where two meromorphic functions share two values ignoring multiplicity and share other two values with multiplicities trucated by 2. Previously, the first author proved that for $n\ge 2,$ there are at most two linearly nondegenerate meromorphic mappings of $\mathbb C^m$ into $\mathbb P^n(\mathbb C)$ sharing $2n+2$ hyperplanes ingeneral position ignoring multiplicity. In this article, we will show that if two meromorphic mappings $f$ and $g$ of $\mathbb C^m$ into $\mathbb P^n(\mathbb C)$ share $2n+1$ hyperplanes ignoring multiplicity and another hyperplane with multiplicities trucated by $n+1$ then the map $f\times g$ is algebraically degenerate.

description: Glyph-based visualization is an effective tool for depicting multivariate information. Since sorting is one of the most common analytical tasks performed on individual attributes of a multi-dimensional data set, this motivates the hypothesis that introducing glyph sorting would significantly enhance the usability of glyph-based visualization. In this paper, we present a glyph-based conceptual framework as part of a visualization process for interactive sorting of multivariate data. We examine several technical aspects of glyph sorting and provide design principles for developing effective, visually sortable glyphs. Glyphs that are visually sortable provide two key benefits: 1) performing comparative analysis of multiple attributes between glyphs and 2) to support multi-dimensional visual search. We describe a system that incorporates focus and context glyphs to control sorting in a visually intuitive manner and for viewing sorted results in an Interactive, Multi-dimensional Glyph (IMG) plot that enables users to perform high-dimensional sorting, analyse and examine data trends in detail. To demonstrate the usability of glyph sorting, we present a case study in rugby event analysis for comparing and analysing trends within matches. This work is undertaken in conjunction with a national rugby team. From using glyph sorting, analysts have reported the discovery of new insight beyond traditional match analysis.

description: Using a coupled channel unitary approach, combining the heavy quark spin symmetry and the dynamics of the local hidden gauge, we investigate the meson-meson interaction with hidden beauty and obtain several new states. Both I=0 and I=1 states are analyzed and it is shown that in the I=1 sector, the interactions are too weak to create any bound states within our framework. In total, we predict with confidence the existence of 6 bound states, and weakly bound 6 more possible states. The existence of these weakly bound states depend on the influence of the coupled channel effects.

The Observed Age Gradient in the Milky Way -- as a Test for theories of spiral arm structure

Year: 2022
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Some important predictions from 4 main models of spiral arm formation are tested here, using observational data acquired for the Milky Way galaxy. Many spiral arm models (density wave, tidal wave, nuclear Lyapunov tube, or dynamic transient wave) have some consistencies with some of the observations, and some inconsistencies. Our 4 tests consist of the relative locations and relative speeds of different arm tracers away from the dust lane, and the global arm pitch angle as obtained over two Galactic quadrants and several Galactic radii, as well as the arm's continuity of shape from Galactic quadrant IV to Galactic quadrant I. In the Milky Way, an age gradient is observed from different arm tracers, amounting to 12.9 +/-1.1 Myrs/kpc, or a relative speed away from the dust lane of 76 +/-10 km/s. The presence of an age gradient is predicted by the density waves, but is not consistent with the predictions of the tidal waves, of the nuclear Lyapunov tubes, nor of the dynamic transient recurrent waves.

description: Separating carbon dioxide (CO₂) from gaseous streams released into the atmosphere is becoming critical due to its greenhouse effect. Membrane technology is one of the promising technologies for CO₂ capture. SAPO-34 filler was incorporated in polymeric media to synthesize mixed matrix membrane (MMM) and enhance the CO₂ separation performance of this process. Despite relatively extensive experimental studies, there are limited studies that cover the modeling aspects of CO₂ capture by MMMs. This research applies a special type of machine learning modeling scenario, namely, cascade neural networks (CNN), to simulate as well as compare the CO₂/CH₄ selectivity of a wide range of MMMs containing SAPO-34 zeolite. A combination of trial-and-error analysis and statistical accuracy monitoring has been applied to fine-tune the CNN topology. It was found that the CNN with a 4-11-1 topology has the highest accuracy for the modeling of the considered task. The designed CNN model is able to precisely predict the CO₂/CH₄ selectivity of seven different MMMs in a broad range of filler concentrations, pressures, and temperatures. The model predicts 118 actual measurements of CO₂/CH₄ selectivity with an outstanding accuracy (i.e., AARD = 2.92%, MSE = 1.55, R = 0.9964).

description: In order to explain the origin of the deep red color of copper glazes on ceramics, a ceramist has elaborated, by firing under reducing atmosphere, a significant number of tiles. The analysis of the structure and composition of a representative sample by TEM and EELS, followed by an optical characterization and an optical modeling using the radiative transfer approach (four-flux model) have enabled a comprehensive explanation of the origin of the color in these glazes. The presence of two families of copper nanoparticles in the vitreous matrix. The first, purely absorbing, of diameter 10-50 nm, essentially creates color by a substractive process. The second, due to its larger diameter, 100 nm or more, mainly acts on color by scattering of the visible light. Both act competitively in the layer. A color chart of all the hues which can be reached by this technique has eventually been theoretically calculated.

description: Context: Despite the low elemental deuterium abundance in the Galaxy, enhanced molecular D/H ratios have been found in the environments of low-mass star-forming regions and, in particular, the Class 0 protostar IRAS 16293-2422. Aims: The key program Chemical HErschel Surveys of Star forming regions (CHESS) aims at studying the molecular complexity of the interstellar medium. The high sensitivity and spectral resolution of the Herschel/HIFI instrument provide a unique opportunity to observe the fundamental 1_{1,1}-0_{0,0} transition of ortho-D2O at 607 GHz and the higher energy 2_{1,2}-1_{0,1} transition of para-D2O at 898 GHz, both of which are inaccessible from the ground. Methods: The ortho-D2O transition at 607 GHz was previously detected. We present in this paper the first tentative detection for the para-D2O transition at 898 GHz. The spherical Monte Carlo radiative transfer code RATRAN was used to reproduce the observed line profiles of D2O with the same method that was used to reproduce the HDO and H2-18O line profiles in IRAS 16293-2422. Results: As for HDO, the absorption component seen on the D2O lines can only be reproduced by adding an external absorbing layer, possibly created by the photodesorption of the ices at the edges of the molecular cloud. The D2O column density is found to be about 2.5e12 cm^{-2} in this added layer, leading to a D2O/H2O ratio of about 0.5%. At a 3 sigma uncertainty, upper limits of 0.03% and 0.2% are obtained for this ratio in the hot corino and the colder envelope of IRAS 16293-2422, respectively. Conclusions: The deuterium fractionation derived in our study suggests that the ices present in IRAS 16293-2422 formed on warm dust grains (~15-20 K) in dense (~1e4-5e4 cm^{-3}) translucent clouds. These results allow us to address the earliest phases of star formation and the conditions in which ices form.

description: (abridged) We correlated near-infrared stellar H-Ks colour excesses of background stars from NTT/SOFI with the far-IR optical depth map, tauFIR, derived from Herschel 160, 250, 350, and 500 um data. The Herschel maps were also used to construct a model for the cloud to examine the effect of temperature gradients on the estimated optical depths and dust absorption cross-sections. A linear correlation is seen between the colour H-Ks and tauFIR up to high extinctions (AV ~ 25). The correlation translates to the average extinction ratio A250um/AJ = 0.0014 +/- 0.0002, assuming a standard near-infrared extinction law and a dust emissivity index beta=2. Using an empirical NH/AJ ratio we obtain an average absorption cross-section per H nucleus of sigmaH(250um) = (1.8 +/- 0.3) * 10^(-25) cm^2 / H-atom, corresponding to a cross-section per unit mass of gas kappaG(250 um) = 0.08 +/- 0.01 cm^2 / g. The cloud model however suggests that owing to the bias caused by temperature changes along the line-of-sight these values underestimate the true cross-sections by up to 40% near the centre of the core. Assuming that the model describes the effect of the temperature variation on tauFIR correctly, we find that the relationship between H-Ks and tauFIR agrees with the recently determined relationship between sigmaH and NH in Orion A. The derived far-IR cross-section agrees with previous determinations in molecular clouds with moderate column densities, and is not particularly large compared with some other cold cores. We suggest that this is connected to the core not beng very dense (the central density is likely to be ~10^5 cm^-3) and judging from previous molecular line data, it appears to be at an early stage of chemical evolution.

Im zweiten Teil der Arbeit wird eine neue Synthese von keramischen Hohlfasern präsentiert, die aus einer Lösung und einer Kanüle erzeugt werden. Die Funktionalisierung von Polymethylmethacrylat basiert auf einem zweischrittigem Mechanismus, bei dem zunächst die Methoxygruppe des Esters durch ein Diamin ersetzt wird, um eine Verknüpfung zu den koordinierenden Gruppen zu ermöglichen. Durch Röntgenanalysen bestätigt sich, dass das bei etwa 10-20% aller Polymereinheiten eine Anbindung erfolgt. Nach der Bildung der Eisenkomplexe werden die Verbindungen in Lösung gebracht und nach dem gängigen Prinzip versponnen. Dabei zeigt sich, dass diese funktionalisierten Polymere bei der richtigen Wahl des Lösungsmittels verspinnbar bleiben. Durch Mößbauerspektroskopie lässt sich zeigen, dass der Einfluss auf die Kernumgebung gering ist und somit die Eigenschaften der Eisenionen grundsätzlich erhalten bleiben. Im zweiten Teil der Arbeit wird die Synthese von keramischen Hohlfasern aus einer homogenen Polymer/Precursor-Lösung vorgestellt. Sie basiert auf der reaktionsgesteuerten Trennung der Reagenzien, die durch die Bildung von Siliziumdioxid aus Tetrachlorsilan und Luftfeuchtigkeit entsteht. Im anschließenden Kalzinierungsschritt kann nicht nur das Polymer entfernt werden, sondern auch die Oberflächenmorphologie beeinflusst werden und der Fadenradius verringert werden. Die Hohlfasern werden zusätzlich auf den Einfluss der Versuchsparameter geprüft, um den Prozess zu optimieren.

description: We compute the two-loop Sudakov form factor in three-dimensional N=6 superconformal Chern-Simons theory, using generalised unitarity. As an intermediate step, we derive the non-planar part of the one-loop four-point amplitude in terms of box integrals. Our result for the Sudakov form factor is given by a single non-planar tensor integral with uniform degree of transcendentality, and is in agreement with the known infrared divergences of two-loop amplitudes in ABJM theory. We also discuss a number of interesting properties satisfied by related three-dimensional integral functions.

description: We advance spin noise spectroscopy to the ultimate limit of single spin detection. This technique enables the measurement of the spin dynamic of a single heavy hole localized in a flat (InGa)As quantum dot. Magnetic field and light intensity dependent studies reveal even at low magnetic fields a strong magnetic field dependence of the longitudinal heavy hole spin relaxation time with an extremely long T1 of ?180?s at 31 mT and 5 K. The wavelength dependence of the spin noise power discloses for finite light intensities an inhomogeneous single quantum dot spin noise spectrum which is explained by charge fluctuations in the direct neighborhood of the quantum dot. The charge fluctuations are corroborated by the distinct intensity dependence of the effective spin relaxation rate. © 2014 American Physical Society.

description: (Abridged) We analyze chemical and kinematical properties of about 850 FGK solar neighborhood long-lived dwarfs observed with the HARPS high-resolution spectrograph. The stars in the sample have logg > 4 dex, 5000 < Teff < 6500 K, and -1.39 < [Fe/H] < 0.55 dex. We apply a purely chemical analysis approach based on the [alpha/Fe] vs. [Fe/H] plot to separate Galactic stellar populations into the thin disk, thick disk and high-alpha metal-rich (hamr). Our analysis shows a negative gradient of the rotational velocity of the thin disk stars with [Fe/H] (-17 km s^-1 dex^-1), and a steep positive gradient for both the thick disk and hamr stars with the same magnitude of about +42 km s^-1 dex^-1. For the thin disk stars we observed no correlation between orbital eccentricities and metallicity, but observed a steep negative gradient for the thick disk and hamr stars with practically the same magnitude (about -0.18 dex^-1). Our results suggest that radial migration played an important role in the formation and evolution of the thin disk. For the thick disk stars it is not possible to reach a firm conclusion about their origin. Based on the eccentricity distribution of the thick disk stars only their accretion origin can be ruled out, and the heating and migration scenario could explain the positive steep gradient of V_phi with [Fe/H]. Analyzing the hamr stellar population we found that they share properties of both the thin and thick disk population. A comparison of the properties of the hamr stars with that of the subsample of stars from the N-body/SPH simulation using radial migration suggest that they may have originated from the inner Galaxy. Further detailed investigations would help to clarify their exact nature and origin.

On Memory and Structural Dynamism in Excitable Cellular Automata with Defensive Inhibition

description: Commonly studied cellular automata are memoryless and have fixed topology of connections between cells. However by allowing updates of links and short-term memory in cells we may potentially discover novel complex regimes of spatio-temporal dynamics. Moreover by adding memory and dynamical topology to state update rules we somehow forge elementary but non-traditional models of neurons networks (aka neuron layers in frontal parts). In present paper we demonstrate how this can be done on a self-inhibitory excitable cellular automata. These automata imitate a phenomenon of inhibition caused by high-strength stimulus: a resting cell excites if there are one or two excited neighbors, the cell remains resting otherwise. We modify the automaton by allowing cells to have few-steps memories, and make links between neighboring cells removed or generated depending on states of the cells.
