Detection and Characterization of Exoplanets and Disks using Projections on Karhunen-Loeve Eigenimages

description: We describe a new method to achieve point spread function (PSF) subtractions for high- contrast imaging using Principal Component Analysis (PCA) that is applicable to both point sources or extended objects (disks). Assuming a library of reference PSFs, a Karhunen-Lo`eve transform of theses references is used to create an orthogonal basis of eigenimages, on which the science target is projected. For detection this approach provides comparable suppression to the Locally Optimized Combination of Images (LOCI) algorithm, albeit with increased robustness to the algorithm parameters and speed enhancement. For characterization of detected sources the method enables forward modeling of astrophysical sources. This alleviates the biases in the astrometry and photometry of discovered faint sources, which are usually associated with LOCI- based PSF subtractions schemes. We illustrate the algorithm performance using archival Hubble Space Telescope (HST) images, but the approach may also be considered for ground-based data acquired with Angular Differential Imaging (ADI) or integral-field spectrographs (IFS).

Radiation-driven Fountain and Origin of Torus around Active Galactic Nuclei
Creators: name: Wada, Keiichi

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We propose a plausible mechanism to explain the formation of the so-called "obscuring tori" around active galactic nuclei (AGNs) based on three-dimensional hydrodynamic simulations including radiative feedback from the central source. The X-ray heating and radiation pressure on the gas are explicitly calculated using a ray-tracing method. This radiation feedback drives a "fountain", that is, a vertical circulation of gas in the central a few to tens parsecs. Interaction between the non-steady outflows and inflows causes the formation of a geometrically thick torus with internal turbulent motion. As a result, the AGN is obscured for a wide range of solid angles. In a quasi-steady state, the opening angles for the column density toward a black hole < 10^23 cm^-2 are approximately +-30 deg and +-50 deg for AGNs with 10% and 1% Eddington luminosity, respectively. Mass inflows through the torus coexist with the outflow and internal turbulent motion, and the average mass accretion rate to the central parsec region is 2x10^-4 ~ 10^-3, M_sun/yr this is about ten times smaller than accretion rate required to maintain the AGN luminosity. This implies that relatively luminous AGN activity is intrinsically intermittent or that there are other mechanisms, such as stellar energy feedback, that enhance the mass accretion to the center.

title: A Study of the Aeroacoustics of Swept Propellers for Small Unmanned Aerial Vehicles
Creators: name: Wiedemann, Arthur David
Publisher: name: Old Dominion University Libraries
Year: 2020

description: In recent years, small unmanned aerial vehicles (UAVs) have increased in availability and use in both public and commercial sectors. This increased use of small UAVs or “drones” has the unfortunate consequence of introducing excessive noise into communities where they operate. Implementation of noise reduction methods is necessary if we wish to see expanded use of drones in public areas. With electric propulsion, the primary source of noise is the rotor/propeller used in contemporary multi-rotor configurations. In this thesis, the aerodynamics and acoustic behavior of various swept propellers is examined with computational and experimental methods.

A family of propeller geometries was established, with test articles machined from aluminum. A straight 16x11.363-inch propeller was used as a control for the nonconventional 15, 35, and 55 degree swept propellers. These propellers have a backwards sweeping blade centerline designed to “de-phase” the far-field acoustic pressure. The aerodynamic properties were collected in ODU’s low speed wind tunnel and an acoustic experiment was conducted outdoors to determine the noise characteristics of the propeller while hovering. The computational analysis was done with NASA’s Aircraft Noise Prediction Program 2 (ANOPP2). This program used the Farrassat-1A Formulation to integrate and propagate acoustic pressures generated by the propellers to observers in the far field at various RPM and distances for several propeller shapes. Overall, the aerodynamic efficiency of the non-conventional propellers did not sway from the conventional, straight propeller design. However, the dBA produced by each propeller requires further study, as the differences in sound pressure level between the designs could not be determined due to external environmental factors.
Quasi-Valuations Extending a Valuation

description: Suppose $F$ is a field with valuation $v$ and valuation ring $O_{v}$, $E$ is a finite field extension and $w$ is a quasi-valuation on $E$ extending $v$. We study quasi-valuations on $E$ that extend $v$; in particular, their corresponding rings and their prime spectrums. We prove that these ring extensions satisfy INC (incomparability), LO (lying over), and GD (going down) over $O_{v}$; in particular, they have the same Krull Dimension. We also prove that every such quasi-valuation is dominated by some valuation extending $v$. Under the assumption that the value monoid of the quasi-valuation is a group we prove that these ring extensions satisfy GU (going up) over $O_{v}$, and a bound on the size of the prime spectrum is given. In addition, a 1:1 correspondence is obtained between exponential quasi-valuations and integrally closed quasi-valuation rings. Given $R$, an algebra over $O_{v}$, we construct a quasi-valuation on $R$; we also construct a quasi-valuation on $R \otimes_{O_{v}} F$ which helps us prove our main Theorem. The main Theorem states that if $R \subseteq E$ satisfies $R \cap F=O_{v}$ and $E$ is the field of fractions of $R$, then $R$ and $v$ induce a quasi-valuation $w$ on $E$ such that $R=O_{w}$ and $w$ extends $v$; thus $R$ satisfies the properties of a quasi-valuation ring.

description: Fluid mechanics can be formulated on dynamical surfaces of arbitrary co-dimension embedded in a background space-time. This has been the main object of study of the blackfold approach in which the emphasis has primarily been on stationary fluid configurations. Motivated by this approach we show under certain conditions that a given stationary fluid configuration living on a dynamical surface of vanishing thickness and satisfying locally the first law of thermodynamics will behave like an elastic brane when the surface is subject to small deformations. These results, which are independent of the number of space-time dimensions and of the fluid arising from a gravitational dual, reveal the (electro)elastic character of (charged) black branes when considering extrinsic perturbations.

description: We give an elementary derivation of the chiral magnetic effect based on a strong magnetic field lowest-Landau-level projection in conjunction with the well-known axial anomalies in two- and four-dimensional space-time. The argument is general, based on a Schur decomposition of the Dirac operator. In the dimensionally reduced theory, the chiral magnetic effect is directly related to the relativistic form of the Peierls instability, leading to a spiral form of the condensate, the chiral magnetic spiral. We then discuss the competition between spin projection, due to a strong magnetic field, and chirality projection, due to an instanton, for light fermions in QCD and QED. The resulting asymmetric distortion of the zero modes and near-zero modes is another aspect of the chiral magnetic effect.

description: The financial market and turbulence have been broadly compared on account of the same quantitative methods and several common stylized facts they shared. In this paper, the She-Leveque (SL) hierarchy, proposed to explain the anomalous scaling exponents deviated from Kolmogorov monofractal scaling of the velocity fluctuation in fluid turbulence, is applied to study and quantify the hierarchical structure of stock price fluctuations in financial markets. We therefore observed certain interesting results: (i) The hierarchical structure related to multifractal scaling generally presents in all the stock price fluctuations we investigated. (ii) The quantitatively statistical parameters that describes SL hierarchy are different between developed financial markets and emerging ones, distinctively. (iii) For the high-frequency stock price fluctuation, the hierarchical structure varies with different time period. All these results provide a novelty analogy in turbulence and financial market dynamics and a insight to deeply understand the multifractality in financial markets.

CDS pricing under Basel III: capital relief and default protection

Subjects: subject: Pricing of Securities (q-fin.PR)
subject: FOS: Economics and business

description: Basel III introduces new capital charges for CVA. These charges, and the Basel 2.5 default capital charge can be mitigated by CDS. Therefore, to price in the capital relief that CDS contracts provide, we introduce a CDS pricing model with three legs: premium; default protection; and capital relief. If markets are complete, with no CDS bond basis, then CDSs can be replicated by taking short positions in risky floating bonds issued by the reference entity and a riskless bank account. If these conditions do not hold, then it is theoretically possible that the capital relief that CDSs provide may be priced in. Thus our model provides bounds on the CDS-implied hazard rates when markets are incomplete. Under simple assumptions we show that 20% to over 50% of observed CDS spread could be due to priced in capital relief. Given that this is different for IMM and non-IMM banks will we see differential pricing?

Beyond the RPA on the cheap: improved correlation energies with the efficient "Radial Exchange Hole" kernel

description: The "ACFD-RPA" correlation energy functional has been widely applied to a variety of systems to successfully predict energy differences, and less successfully predict absolute correlation energies. Here we present a parameter-free exchange-correlation kernel that systematically improves absolute correlation energies, while maintaining most of the good numerical properties that make the ACFD-RPA numerically tractable. The "RXH" kernel is constructed to approximate the true exchange kernel via a carefully weighted, easily computable radial averaging. Correlation energy errors of atoms with two to eighteen electrons show a thirteenfold improvement over the RPA and a threefold improvement over the related "PGG" kernel, for a mean absolute error of 13mHa or 5%. The average error is small compared to all but the most difficult to evaluate kernels. van der Waals $C_6$ coefficients are less well predicted, but still show improvements on the RPA, especially for highly polarisable Li and Na.

description: We study the relative fraction of low and high surface brightness galaxies (LSBGs and HSBGs) at void walls in the SDSS DR7. We focus on galaxies in equal local density environments. We assume that the host dark-matter halo mass (for which we use SDSS group masses) is a good indicator of local density. This analysis allows to examine the behavior of the abundance of LSBG and HSBG galaxies at a fixed local density and distinguish the large-scale environment defined by the void geometry. We compare galaxies in the field, and in the void walls; the latter are defined as the volume of void shells of radius equal to that of the void. We find a significant decrement, a factor $\sim 4$, of the relative fraction of blue, active star-forming LSBGs in equal mass groups at the void walls and the field. This decrement is consistent with an increase of the fraction of blue, active star-forming HSBGs. By contrast, red LSBGs and HSBGs show negligible changes. We argue that these results are consistent with a scenario where LSBGs with blue colors and strong star formation activity at the void walls are fueled by gas from the expanding void regions. This process could lead to LSBG to HSBG transformations.

description: We introduce a new method to detect solar-like oscillations in frequency power spectra of stellar observations, under conditions of very low signal to noise. The Moving-Windowed-Power-Search, or MWPS, searches the power spectrum for signatures of excess power, over and above slowly varying (in frequency) background contributions from stellar granulation and shot or instrumental noise. We adopt a false-alarm approach (Chaplin et al. 2011) to ascertain whether flagged excess power, which is consistent with the excess expected from solar-like oscillations, is hard to explain by chance alone (and hence a candidate detection). We apply the method to solar photometry data, whose quality was systematically degraded to test the performance of the MWPS at low signal-to-noise ratios. We also compare the performance of the MWPS against the frequently applied power-spectrum-of-power-spectrum (PSxPS) detection method. The MWPS is found to outperform the PSxPS method.

description: Although the properties of the narrow-line region (NLR) of active galactic nuclei(AGN) have been deeply studied by many authors in the past three decades, many questions are still open. The main goal of this work is to explore the NLR of Seyfert galaxies by collecting a large statistical spectroscopic sample of Seyfert 2 and Intermediate-type Seyfert galaxies having a high signal-to-noise ratio in order to take advantage of a high number of emission-lines to be accurately measured. 2153 Seyfert 2 and 521 Intermediate-type Seyfert spectra were selected from Sloan Digital Sky Survey - Data Release 7 (SDSS-DR7) with a diagnostic diagram based on the oxygen emission-line ratios. All the emission-lines, broad components included, were measured by means of a self-developed code, after the subtraction of the stellar component. Physical parameters, such as internal reddening, ionization parameter, temperature, density, gas and stellar velocity dispersion were determined for each object. Furthermore, we estimated mass and radius of the NLR, kinetic energy of the ionized gas, and black-hole accretion rate. From the emission-line analysis and the estimated physical properties, it appears that the NLR is similar in Seyfert 2 and Intermediate-Seyfert galaxies. The only differences, lower extinction, gas kinematics in general not dominated by the host galaxy gravitational potential and higher percentage of [O III]5007 blue asymmetries in Intermediate-Seyfert can be ascribed to an effect of inclination of our line of sight with respect to the torus axis.

description: Abstract. Corporate social responsibility (CSR) is a recent introduction to the Chinese stock markets, and related research is limited. Using a sample of Chinese listed firms on the A-share market in China, this paper investigates whether CSR ratings can influence the stock returns and how that influence differs across state-owned and non-state-owned firms. Conflicting with existing research in the US and European countries, CSR ratings have no significant influence on stock returns in China, regardless of government ownership. Robustness checks show that CSR does not affect the values of those companies either. I show that the insignificance of government ownership in this paper does not result from selection bias. The explanation for the insignificant results remains an open question.
The importance of anisotropic Coulomb interactions and exchange to the band gap and antiferromagnetism of β-MnO2 from DFT+U

description: First principles density functional theory (DFT) is used to investigate the electronic structure of β-MnO2. From collinear spin polarized calculations we find that DFT+U_Eff predicts a gapless ferromagnet in contrast with experiment which indicates an insulating antiferromagnet. The inclusion of anisotropic Coulomb and exchange interactions in the DFT+U approach, defining U and J explicitly, corrects these errors and leads to an antiferromagnetic ground state with a fundamental gap of 0.8 eV consistent with low temperature experiments. To our knowledge, this work on β-MnO2 represents the first demonstration of a case in which the application of fully anisotropic interactions in DFT+U determines the magnetic order and consequent band gap, while the more commonly used effective U approach fails. Such effects are argued to be of importance in many insulating materials. The mechanism leading to an increase in band gap due to anisotropic interactions is highlighted by analytical calculation of DFT+U d-orbital eigenvalues obtained within a Kanamori-type model. Magnetic coupling constants obtained by the fitting of a Heisenberg spin Hamiltonian to the energies of a range of magnetic states assist in rationalizing the finding that anisotropic interactions enhance the stability of the experimentally observed helical antiferromagnetic order. The plane wave PAW method yields poorer results for the exchange couplings than full-potential LAPW calculations. Finally, we compare the DFT+U results with exchange couplings obtained from hybrid functionals. It is argued that anisotropic interactions should be included in DFT+U if the results are to be properly compared with those from hybrid functionals.

description: Intensive research has been carried out on III-V semiconductors for over a century due to their various applications in the field of Microelectronics, Optics, and Photonics. Among III-V materials, the III-nitrides, for example Aluminum Nitride, Indium Nitride, Gallium Nitride and their ternary alloys are known for their unique properties. All the III-Nitride Compounds are direct bandgap semiconductors with a bandgap ranging from 0.7 eV to 6.2 eV covering the entire visible region and extending to the UV region as well. Despite having many applications, fabricating good quality thin films without defects is quite a challenge. They are typically grown using a process called Molecular Beam Epitaxy (MBE) on substrates, such as sapphire or silicon carbide (SiC), but the process and materials are not very economical. The main aim of this thesis is to deposit high quality III-Nitrides thin films with the help of Reactive Magnetron Sputtering on various substrates. Various characterization techniques are used to analyze the samples and understand the effect of various deposition parameters on the quality of the films.

description: The field of forensics leans heavily on the development of novel methods of crime scene analysis. Many of these methods have their roots in biology and chemistry laboratories. Our research describes how plants may allow indirect detection of a buried human body. We hypothesized that specific molecules from a buried cadaver are absorbed by nearby plant systems during decomposition. We grew two flowering plants from seed: Cosmos bipinnatus (Cosmos) and Rudbeckia hirta (Black-Eyed Susan). Ground beef was buried in some of the pots to imitate organic matter from a human cadaver. After 3 weeks, we collected plant and soil samples, and analyzed them using thin layer chromatography and mass spectrometry, to identify bovine proteins, hormones, and amino acids. The thin layer chromatography profiles suggested that specific proteins from the beef were also present in our plant samples. This indicates that the plants grown with beef in the soil actively absorbed beef proteins, supporting our hypothesis. Mass spectrometry data will confirm our hypothesis. Further experiments can be done to supplement our preliminary data. If our results prove to be authentic and reproducible, they may provide a basis for the development of new forensics tools to detect the presence of human remains. If developed, these tools could greatly contribute to the efficiency and accuracy of evidence collection at crime scenes.

description: Eine Bibliographie zur Didaktik des Sachunterrichts zu erstellen, ist nicht nur ein zeitintensives und mühevolles, sondern auch ein sehr anspruchvolles Unternehmen, weist doch die Didaktik des Sachunterrichts im Vergleich zu anderen Fachdidaktiken einen ausgesprochen hohen Grad an Komplexität auf. Dieser Aufgabe hat sich Marcus Rauterberg mit seiner „Bibliographie Sachunterricht“ gestellt und damit ein Buch vorgelegt, das im Ergebnis weitaus mehr ist als eine reine Literatursammlung von sachunterrichtsdidaktischer Relevanz. Der Vorliegende Text ist eine Rezension dieser Bibliographie.

description: We investigate n-gluon scattering amplitudes in the multi-Regge region of N=4 supersymmetric Yang-Mills theory at strong coupling. Through a careful analysis of the thermodynamic bubble ansatz (TBA) for surfaces in AdS5 with n-g(lu)on boundary conditions we demonstrate that the multi-Regge limit probes the large volume regime of the TBA. In reaching the multi-Regge regime we encounter wall-crossing in the TBA for all n>6. Our results imply that there exists an auxiliary system of algebraic Bethe ansatz equations which encode valuable information on the analytical structure of amplitudes at strong coupling.

description: Приводится описание конструкции кремниевого фотоприемника, содержащего три последовательно расположенных фотодиода. Диапазоны спектральной чувствительности по уровню 0,5 составили: для первого канала — 0,28 … 0,52 мкм, для второго — 0,45 … 0,95 мкм, для третьего — 0,9 … 1,08 мкм. Приводятся сведения о технологии фотоприемника. Для получения мелкозалегающих слоёв первого канала проводилось ионное легирование донорной примесью. Второй канал формировался диффузией бора на небольшую глубину с пониженной поверхностной концентрацией. Инфракрасный канал создавался диффузией бора с тыльной стороны пластины на большую глубину. В работе приведены значения барьерной емкости и обратных токов фотодиодов.

description: A set of LaAlO3/SrTiO3 (LAO-STO) interfaces has been probed by X-ray photoemission spectroscopy in order to contrast and compare the effects of LAO overlayer thickness and of the growth conditions on the electronic properties of these heterostructures. These effects are tracked by considering the band-offset and the density of Ti3+ states, respectively. It is shown that the dominant effects on the local electronic properties are determined by the O2 partial pressure during the growth. In particular, a low P(O2) yields Ti3+ states with higher density and lower binding energy as compared to the sample grown at high P(O2) or to the bare STO reference sample. Band offset effects are all below about 0.7 eV, but a careful analysis of Ti 2p and Sr 3d peaks shows that valence band offsets can be at the origin of the observed peak width. In particular, the largest offset is shown by the conducting sample, that displays the largest Ti 2p and Sr 3d peak widths.

description: Liebe Kollegin, lieber Kollege aus dem SachunterrichtIm Folgenden mute ich Dir etwas zu. Ich mute Dir erstens zu, einen Text zu lesen, der – zumindest teilweise – eigentlich gar nicht für Dich bestimmt war. Zweitens mute ich Dir ein Thema zu, von dem Du vielleicht gar nichts wissen willst. Und Drittens mute ich Dir eine vermutlich ungewöhnliche Form von Text zu, in der ich mir – entschuldige das nachträglich – anmaße, Dich zu duzen. Zumutungen dieser Art lassen sich (mit ein bisschen Phantasie) auch so verstehen: Dass ich Dir das zu mute, ist nicht nur eine Zumutung, sondern auch Zuweisung von Mut (sich, auch wenn es ungewöhnlich ist, damit auseinanderzusetzen).Der erste Teil des Textes wurde geschrieben für eine Kolumne in der Zeitschrift des BDK – Fachverband für Kunstpädagogik e.V. Seit Ausgabe 3/2000 schreibe ich für die BDK-Mitteilungen kleine Essays unter dem Titel „e-mails from http://kunst.erzwiss.uni hamburg.de“. Die immer als Korrespondenzen mit einer gewissen „D.“ formulierten Texte kreisen zumeist um das Thema „Neue Medien“ und Kunstpädagogik.Die Adressatin habe ich mir von Jacques Derrida geborgt. In seinen „Postkarten von Sokrates bis an Freud und jenseits“ schreibt er an eine ominöse D.: „Du würdest einen LiebesBrief lesen, ein bißchen retro, den letzten der Geschichte. Aber Du hast ihn noch nicht bekommen. Ja, mangels oder wegen übermäßiger Adresse eignet er sich, in alle Hände zu fallen: eine Postkarte, ein offener Brief, wo das Geheimnis erscheint, aber unentzifferbar. [...] sie macht aus Dir, was Du willst, sie nimmt D., sie lässt D., sie gibt D.“iAls Arbeitshypothese unterstelle ich ein „Du“. D., das heißt Du, Dich, Dir usw. Ich stelle mir (und Dir) also D. vor als eine Kollegin aus der Kunstpädagogik, mit der ich seit Jahren „auf Du“ bin. Vielleicht haben wir zusammen studiert oder kennen uns von irgendwelchen Fachtagungen o.ä. D. ist Fachfrau auf Ihrem Gebiet, mit reichlich Unterrichtserfahrung und mit allen fachdidaktischen Wassern gewaschen.Aber D. ist eben auch eine „übermäßige Adresse“. Was ich ihr zu sagen habe, betrifft nicht nur die Kunstpädagogik. eMails an D. eignen sich in alle Hände zu fallen. Und nun ist eine in Deine Hände gefallen.

description: We study a sample of 883 sources detected in a deep Very Large Array survey at 1.4 GHz in the Extended Chandra Deep Field South. The paper focuses on the identification of their optical and infrared (IR) counterparts. We use a likelihood ratio technique that is particularly useful when dealing with deep optical images to minimize the number of spurious associations. We find a reliable counterpart for 95% of our radio sources. Most of the counterparts (74%) are detected at optical wavelengths, but there is a significant fraction (21%) only detectable in the IR. Combining newly acquired optical spectra with data from the literature we are able to assign a redshift to 81% of the identified radio sources (37% spectroscopic). We also investigate the X-ray properties of the radio sources using the Chandra 4 Ms and 250 ks observations. In particular, we use a stacking technique to derive the average properties of radio objects undetected in the Chandra images. The results of our analysis are collected in a new catalog containing the position of the optical/IR counterpart, the redshift information and the X-ray fluxes. It is the deepest multi-wavelength catalog of radio sources, which will be used for future study of this galaxy population.
