description: We investigate the link between AGN activity, star-formation and stellar mass of the host galaxy at 010.2 threshold. Moreover, the stellar populations of AGN hosts are found to be older with respect to star-forming and composites galaxies. This could be due to the the tendency of AGN to reside in massive hosts. The dependence of the AGN classification on the stellar mass is in agreement with what has been already found in previous studies. It is consistent with, together with the evidence of older stellar populations inhabiting the AGN-like galaxies, the downsizing scenario. In particular, our evidence points to an evolutionary scenario where the AGN-feedback is capable of quenching the star formation in the most massive galaxies. Therefore, the AGN-feedback is the best candidate for initiating the passive evolutionary phase of galaxies.

description: It is known that graded cyclic modules over $S=K[x,y]$ have the Weak Lefschetz Property (WLP). This is not true for non-cyclic modules over $S$. The purpose of this note is to study which conditions on $S$-modules ensure the WLP. We give an algorithm to test the WLP for graded modules with fixed Hilbert function. In particular, we prove that indecomposable graded modules over $S$ with the Hilbert function $(h_0,h_1)$ have the WLP.

description: The Causal Dynamical Triangulation model of quantum gravity (CDT) is a proposition to evaluate the path integral over space-time geometries using a lattice regularization with a discrete proper time and geometries realized as simplicial manifolds. The model admits a Wick rotation to imaginary time for each space-time configuration. Using computer simulations we determined the phase structure of the model and discovered that it predicts a de Sitter phase with a four-dimensional spherical semi-classical background geometry. The model has a transfer matrix, relating spatial geometries at adjacent (discrete lattice) times. The transfer matrix uniquely determines the theory. We show that the measurements of the scale factor of the (CDT) universe are well described by an effective transfer matrix where the matrix elements are labelled only by the scale factor. Using computer simulations we determine the effective transfer matrix elements and show how they relate to an effective minisuperspace action at all scales.

description: Web spaces, wide web spaces and worldwide web spaces (alias C-spaces) provide useful generalizations of continuous domains. We present new characterizations of such spaces and their patch spaces, obtained by joining the original topology with a second topology having the dual specialization order; these patch spaces possess good convexity and separation properties and determine the original web spaces. The category of C-spaces is concretely isomorphic to the category of fan spaces; these are certain quasi-ordered spaces having neighborhood bases of fans, where a fan is obtained by deleting a finite number of principal dual ideals from a principal dual ideal. Our approach has useful consequences for domain theory, because the T0 web spaces are exactly the generalized Scott spaces associated with locally approximating ideal extensions, and the T0 C-spaces are exactly the generalized Scott spaces associated with globally approximating and interpolating ideal extensions. The characterization of continuous lattices as meet-continuous lattices with T2 Lawson topology and the Fundamental Theorem of Compact Semilattices are extended to non-complete posets. Finally, cardinal invariants like density and weight of the involved objects are investigated. © 2019 Marcel Erné. All rights reserved.

description: We deal with two dynamical systems associated with a Riemannian manifold with boundary. The first one is a system governed by the scalar wave equation, the second is governed by the Maxwell equations. Both of the systems are controlled from the boundary. The inverse problem is to recover the manifold via the relevant measurements at the boundary (inverse data). We show that the inverse data determine a C*-algebras, whose (topologized) spectra are identical to the manifold. By this, to recover the manifold is to determine a proper algebra from the inverse data, find its spectrum, and provide the spectrum with a Riemannian structure. The paper develops an algebraic version of the boundary control method, which is an approach to inverse problems based on their relations to control theory.

description: Given an Eulerian graph G, in the Maximum Eulerian Cycle Decomposition problem, we are interested in finding a collection of edge-disjoint cycles {E_1, E_2, ..., E_k} in G such that all edges of G are in exactly one cycle and k is maximum. We present an algorithm to solve the pricing problem of a column generation Integer Linear Programming (ILP) model introduced by Lancia and Serafini (2016). Furthermore, we propose a greedy heuristic, which searches for minimum size cycles starting from a random vertex, and a heuristic based on partially solving the ILP model. We performed tests comparing the three approaches in relation to the quality of solutions and execution time, using distinct sets of Eulerian graphs, each set grouping graphs with different numbers of vertices and edges. Our experimental results show that the ILP based heuristic outperforms the other methods.

description: Besides the fact that the gamma-ray emission due to radioactive decays is responsible for powering the light curves of Type Ia supernovae (SNe Ia), gamma rays themselves are of particular interest as a diagnostic tool because they provide a direct way to obtain deeper insights into the nucleosynthesis and the kinematics of these explosion events. Focusing on two of the most broadly discussed SN Ia progenitor scenarios - a delayed detonation in a Chandrasekhar-mass white dwarf (WD) and a violent merger of two WDs - we use three-dimensional explosion models and perform radiative transfer simulations to obtain synthetic gamma-ray spectra. Both chosen models produce the same mass of 56Ni and have similar optical properties that are in reasonable agreement with the recently observed supernova SN 2011fe. In contrast to the optical regime, the gamma-ray emission of our two chosen models proves to be rather different. The almost direct connection of the emission of gamma rays to fundamental physical processes occuring in SNe Ia permits additional constraints concerning several explosion model properties that are not easily accessible within other wavelength ranges. Proposed future MeV missions such as GRIPS will resolve all spectral details only for nearby SNe Ia, but hardness ratio and light curve measurements still allow for a distinction of the two different models at 10 and 16 Mpc for an exposure time of 10^6 s, respectively. The possibility to detect the strongest line features up to the Virgo distance will offer the opportunity to build up a first sample of SN Ia detections in the gamma-ray energy range and underlines the importance of future space observatories for MeV gamma rays.

description: Abstract
In this work, we studied the mechanical and electronic properties of the WO3 cubic phase using Density Functional Theory (DFT) with the Generalised Gradient Approximation (GGA). The results obtained for the mechanical properties following geometric optimisation show that the crystalline parameter a(A)=3.835863 for a volume V(A3 )=56.4403 .  The elastic constants obtained are such that C11=579.5320, C12=29.0545 C44=70.54350 confirm the stability of the cubic phase of WO3 with the modulus of compressibility B(Gpa)= 212.5470 and the Young's modulus E(Gpa )=369.0477. We obtained a Debye temperature of 558.5640 K and showed that cubic WO3 exhibits anisotropy for the transverse propagation mode in the [100] and [110] directions. For the lectronic structure, we obtained a gap equal to 0.642 eV. These results from the classical DFT are in good agreement with the theoretical results obtained by the GGA+U approximation (U Hubbard parameter)..

Dennoch werden von der Norm abweichende Lebensstile und Arten des Zusammenlebens meist von Politik, Medien und in gesellschaftspolitischen Diskursen als Besonderheit dargestellt (vgl. Ossmann 2017). So richtet sich in den Medien ein oft irritierter Blick auf nichtmonogame, vor allem polyamoröse Lebensweisen. Das wirft die Frage auf, wie sich Menschen fühlen, die entgegen der überwiegend heteronormativen und monogam ausgerichteten Gesellschaft, zum Beispiel polyamor, leben.

description: The release of hazardous material in a subway station is a dangerous situation for passengers and staff. To achieve an acceptable level of risk, a correct marking of emergency exits and escape routes is essential., For this purpose, underground air dispersion, which depends on source characteristics, the construction layout of the station, and meteorological conditions, must be known. In this paper a micro-scale wind model is combined with a dispersion model to calculate the spread of pollutants underground as well as aboveground for specific scenarios. In particular, the effect of emission temperature on the contamination of the subway facilities was studied. Completely different spots with high concentrations have been calculated for hot and cold sources. Depending on the scenario, an escape route is not always safe, underlining the need for a situation-related adaptive marking system. Further information on the optimisation of a safe way out is provided by the results of an agent-based simulation model. Depending on the number and on the individual characteristics of the agents, the contamination level can be estimated, which could help in the prioritisation process between alternative escape routes.

description: This thesis investigates the transformative potential of carbon materials derived from soft brown coal. A novel method produces high surface-area active carbons in a 'honeycomb monolith’ (HM) configuration that retain their structural integrity as a consequence of a unique hydrogen bonding network. These activated carbons exhibit enhanced porosity, aromaticity, and graphitization. They find application in formaldehyde removal at trace ppm concentrations, offering a cost-effective and regenerable adsorbents material. Ferromagnetic iron-doped HM catalysts are developed for efficient wastewater treatment, achieving high phenol removal rates even after multiple cycles. Additionally, a low-temperature conversion process for turning brown coal into graphitic carbon is explored. This research opens avenues for the versatile use of soft brown coal in various real world environmental applications.

description: We study resonant optical excitations of strongly-interacting Rydberg states of atoms in the presence of relaxations. We employ the quantum stochastic (Monte Carlo) wavefunctions to simulate the dissipative dynamics of tens of atoms in two-dimensional lattices. We show that under typical experimental conditions involving slow Rydberg state decay and sizable relaxation of atomic coherences, on the time scale of several microseconds the atomic ensemble approaches a stationary state in which much of the quantum correlations between the atoms have decayed away. The steady state, however, exhibits strong classical correlations of Rydberg excitation probabilities.

description: It is known that the IR and X-ray luminosities of Active Galactic Nuclei (AGN) are correlated with L_{IR} ~ L_{X}. Moreover, the IR flux ratio between the 5.8 and 3.6 μm bands is a good distinguishing characteristic of AGN or AGN-like behaviour. On the other hand, Galactic X-ray binaries (GXB) are under-luminous in the IR with L_{IR} << L_{X}. Since Ultra-luminous X-ray sources in nearby galaxies may be an intermediate class between AGN and GXB, it is interesting to study if their IR properties indicate which kind of objects they resemble. We use Spitzer IRAC images to identify mid-IR counterparts of bright X-ray sources, detected by Chandra in the elliptical galaxy NGC 1399. We find that for sources with AGN-like IR flux ratios, the IR luminosity strongly correlates with that in X-rays, L_{IR} ~ L_{X}, while for the others, there is no correlation between the two. Some of the former objects may be background AGN. If they are not strongly contaminated by background AGN, this result extends the IR-X-ray luminosity correlation down to L_{X} ~ 10^{39} ergs/s. We calculate their g-z colours and find that the bright X-ray sources with IR counterparts are typically blue in optical color. This is in contrast to typical X-ray sources, without IR counterparts which have predominantly red optical counterparts. We highlight the need for IR or optical spectra of these sources to distinguish background AGN and unveil the effect of the X-ray emission on the different environments of these systems.

description: Semiconductor surfaces were divided into charge categories, i.e. surface acceptor, donor and neutral ones that are suitable for simulations of their properties within a slab model. The potential profiles, close to the charged surface states, accounting for explicit dependence of the point defects energy, were obtained. A termination charge slab model was formulated and analyzed proving that two control parameters of slab simulations exist: the slope and curvature of electric potential profiles which can be translated into a surface and volumetric charge density. The procedures of slab model parameter control are described and presented using examples of the DFT simulations of GaN and SiC surfaces showing the potential profiles, linear or curved, depending on the band charge within the slab. It was also demonstrated that the field at the surface may affect some surface properties in a considerable degree proving that verification of this dependence is obligatory for a precise simulation of the properties of semiconductor surfaces.

description: The coupling between electrons and phonons is at the heart of many fundamental phenomena in physics. In nature, this coupling is generally predetermined for both, molecules and solids. Tremendous advances have been made in controlling electrons and phonons in engineered nanosystems, yet, control over the coupling between these degrees of freedom is still widely lacking. Here, we use a new generation of carbon nanotube devices with movable ultra-clean single and double quantum dots embedded in a mechanical resonator to demonstrate the tailoring of the interactions between electronic and mechanical degrees of freedom on the nanoscale. Exploiting this tunable coupling, we directly image the spatial structure of phonon modes and probe their parity in real space. Most interestingly, we demonstrate selective coupling between individual mechanical modes and internal electronic degrees of freedom. Our results open new vistas for engineering bulk quantum phenomena in a controlled nanoscale setting and offer important new tools for entangling the electronic and mechanical degrees of freedom at the quantum level.

description: The fast escaping set, A(f), of a transcendental entire function f has begun to play a key role in transcendental dynamics. In many cases A(f) has the structure of a spider's web, which contains a sequence of fundamental loops. We investigate the structure of these fundamental loops for functions with a multiply connected Fatou component, and show that there exist transcendental entire functions for which some fundamental loops are analytic curves and approximately circles, while others are geometrically highly distorted. We do this by introducing a real-valued function which measures the rate of escape of points in A(f), and show that this function has a number of interesting properties.

Changes in the environment, namely environmental resource degradation and climate change, can expose their livelihoods to severe pressure, including incidences of food insecurity. At the same time, the spread of modern technology in the form of smartphones and access to the internet opens up reams of opportunities to rural households to improve their income-earning portfolio. Focusing at the household level, this dissertation identifies how these processes affect rural households in Cambodia, Laos, Thailand and Vietnam based on their livelihood strategies in six different essays. It uses these findings to generate ideas how rural livelihoods could be transformed and how development policies could be adjusted so that in the future more households will benefit from the rapid economic development in South-East Asia and avoid to be negatively affected by its external effects.

Bouncing Loop Quantum Cosmology from $F(T)$ gravity

description: The big bang singularity could be understood as a breakdown of Einstein's General Relativity at very high energies. Adopting this viewpoint, other theories, that implement Einstein Cosmology at high energies, might solve the problem of the primeval singularity. One of them is Loop Quantum Cosmology (LQC) with a small cosmological constant that models a universe moving along an ellipse, which prevents singularities like the big bang or the big rip, in the phase space $(H,ρ)$, where $H$ is the Hubble parameter and $ρ$ the energy density of the universe. Using LQC when one considers a model of universe filled by radiation and matter where, due to the cosmological constant, there are a de Sitter and an anti de Sitter solution. This means that one obtains a bouncing non-singular universe which is in the contracting phase at early times. After leaving this phase, i.e., after bouncing, it passes trough a radiation and matter dominated phase and finally at late times it expands in an accelerated way (current cosmic acceleration). This model does not suffer from the horizon and flatness problems as in big bang cosmology, where a period of inflation that increases the size of our universe in more than 60 e-folds is needed in order to solve both problems. The model has two mechanisms to avoid these problems: The evolution of the universe through a contracting phase and a period of super-inflation ($\dot{H}> 0$).
Rayo horizontal en átmosfera planoparalela

description: Este artículo investiga la trayectoria de un rayo de luz lanzado horizontalmente a 1000 m de altitud en una atmósfera en la que la presión y, por ende, el índice de refracción decrecen según la fórmula barométrica. Partiendo del hecho de que el índice de refracción del aire es muy cercano a 1 y que su incremento (n–1) es proporcional a la presión, se modela la variación del índice en las proximidades de 1000 m mediante una aproximación lineal. Esta simplificación permite demostrar, utilizando el principio de Fermat, que el rayo describe un arco circular con un radio de curvatura extremadamente grande, del orden de 3.2×10⁷ m.

El artículo desarrolla el modelo teórico, derivando la expresión del radio de curvatura y la ecuación de la trayectoria, y muestra que, para distancias horizontales moderadas (por ejemplo, 100 km), la desviación vertical del rayo es de aproximadamente 155 m. Se incluyen gráficos generados con TikZ que, mediante escalas independientes en los ejes, ilustran de forma clara y comprensible la sutil curvatura de la trayectoria.

Este estudio es de interés para la comprensión de la refracción atmosférica y sus efectos sobre la propagación de la luz, y ofrece una herramienta didáctica para el análisis de rayos en medios estratificados. El artículo es especialmente relevante para quienes trabajan en óptica atmosférica, física aplicada y áreas relacionadas.

description: Abstract
The conventional healthcare systems have recently undergone a radical transformation due to the incorporation of cutting-edge technologies such as compressive sensing, wireless networks, and cloud computing. Computer-aided diagnosis is one of the most active research topics, which shows a noticeable improvement in the medical field. As a result of the development of intelligent techniques, biomedical data processing has become simpler and less prone to errors. In addition, the internet of things (IoT) infrastructure makes it feasible to provide healthcare from a distance. However, the integration of technologies has led to a rise in security issues. Data security over remote healthcare systems is essential, and represents one of the most significant challenges. Consequently, e-health data security and privacy concerns must be thoroughly investigated. Typically, biomedical data are sensitive to external attacks, and even minor data manipulation can have a significant impact on the final result. In some cases, a wrong diagnosis can be fatal, and in most cases, it can be severe. In this paper, secured healthcare systems based on chaotic mapping techniques are reviewed. Future research in multimedia data security and biomedical image protection could greatly benefit from this work.

description: We present very low temperature (0.15 K) scanning tunneling microscopy and spectroscopy experiments in the layered superconductor LaSb$_2$. We obtain topographic microscopy images with surfaces showing hexagonal and square atomic size patterns, and observe in the tunneling conductance a superconducting gap. We find well defined quasiparticle peaks located at a bias voltage comparable to the weak coupling s-wave BCS expected gap value (0.17 meV). The amount of states at the Fermi level is however large and the curves are significantly broadened. We find T$_c$ of 1.2 K by following the tunneling conductance with temperature.

description: Gerjuoy [Phys. Rev. A 67, 052308 (2003)] has derived a closed- form lower bound for the entanglement of formation of a mixed qubit-qudit system (qudit system has d levels with d>=3. In this paper, inspired by Gerjuoy's method, we propose a scheme that partitions a qubit-qudit system into d(d-1)/2 qubit-qubit systems, which can be treated by all known methods pertinent to qubit-qubit system. The method is demonstrated by a qubit-qudit system (The levels of qudit are d=3 and d=5, respectively)

Direct Ultraviolet Imaging and Spectroscopy of Betelgeuse

description: Direct images of Betelgeuse were obtained over a span of 4 years with the Faint Object Camera on the Hubble Space Telescope. These images reveal the extended ultraviolet continuum emission (about 2 times the optical diameter), the varying overall ultraviolet flux levels and a pattern of bright surface continuum features that change in position and appearance over several months or less. Concurrent photometry and radial velocity measures support the model of a pulsating star, first discovered in the ultraviolet from IUE. Spatially resolved HST spectroscopy reveals a larger extention in chromospheric emissions of Mg II as well as the rotation of the supergiant. Changing localized subsonic flows occur in the low chromosphere that can cover a substantial fraction of the stellar disk and may initiate the mass outflow.

description: Der Vorgang der Geburt geht im gesellschaftlichen Diskurs mit einer klaren Annahme einher: Geburt schafft Leben. Dass Geburt ebenso Anlass, Grund und Auslöser für Tod und das Ende von Leben bedeuten kann, ist in der Inszenierung von Schwangerschaft und Geburt nicht vorgesehen. Der Beitrag betrachtet auf Grundlage empirischer Ergebnisse die Geburt als körperlich-leiblichen Prozess und Schwellenritual im Kontext von Schwangerschaftsverlusten. Anhand der Phänomene von früher Fehlgeburt und Neugeborenentod zeichnet die Autorin nach, welche Rolle die Geburt in den Fällen von schwangerschaftsbedingten Verlusten einnimmt. Dabei wird gefragt, wie die betroffenen Frauen den körperlich-leiblichen Vorgang der Geburt in den hier betrachteten Fällen von Schwangerschaftsverlust beschreiben und welche Formen der Ritualisierung und Routinisierung dabei stattfinden. Zudem wird aufgezeigt, welche Bedeutung der Geburt für das Verlusterleben zukommt und welche Schlüsse sich daraus für Assoziationen des Geburtsvorgangs nicht nur mit der Kategorie des Lebens, sondern auch mit den Kategorien von Tod, Verlust und Abschied ergeben.

description: Using Optimal Control Theory (OCT), we design fast ramps for the controlled transport of Bose-Einstein condensates with atom chips' magnetic traps. These ramps are engineered in the context of precision atom interferometry experiments and support transport over large distances, typically of the order of 1 mm, i.e. about 1,000 times the size of the atomic clouds, yet with durations not exceeding 200 ms. We show that with such transport durations of the order of the trap period, one can recover the ground state of the final trap at the end of the transport. The performance of the OCT procedure is compared to that of a Shortcut-To-Adiabaticity (STA) protocol and the respective advantages/disadvantages of the OCT treatment over the STA one are discussed.
