description: A parameterizable recommender system based on the Big Data processing framework Spark is introduced, which takes multiple tonal properties of music into account and is capable of recommending music based on a user's personal preferences. The implemented system is fully scalable; more songs can be added to the dataset, the cluster size can be increased, and the possibility to add different kinds of audio features and more state-of-the-art similarity measurements is given. This thesis also deals with the extraction of the required audio features in parallel on a computer cluster. The extracted features are then processed by the Spark based recommender system, and song recommendations for a dataset consisting of approximately 114000 songs are retrieved in less than 12 seconds on a 16 node Spark cluster, combining eight different audio feature types and similarity measurements.
description: Ein parametrisierbares Empfehlungssystem, basierend auf dem Big Data Framework Spark, wird präsentiert. Dieses berücksichtigt verschiedene klangliche Eigenschaften der Musik und erstellt Musikempfehlungen basierend auf den persönlichen Vorlieben eines Nutzers. Das implementierte Empfehlungssystem ist voll skalierbar. Mehr Lieder können dem Datensatz hinzugefügt werden, mehr Rechner können in das Computercluster eingebunden werden und die Möglichkeit andere Audiofeatures und aktuellere Ähnlichkeitsmaße hizuzufügen und zu verwenden, ist ebenfalls gegeben. Des Weiteren behandelt die Arbeit die parallele Berechnung der benötigten Audiofeatures auf einem Computercluster. Die Features werden von dem auf Spark basierenden Empfehlungssystem verarbeitet und Empfehlungen für einen Datensatz bestehend aus ca. 114000 Liedern können unter Berücksichtigung von acht verschiedenen Arten von Audiofeatures und Abstandsmaßen innerhalb von zwölf Sekunden auf einem Computercluster mit 16 Knoten berechnet werden.

description: Context. Millimetric observations have measured high degrees of molecular deuteration in several species seen around low-mass protostars. The Herschel Space Telescope, launched in 2009, is now providing new measures of the deuterium fractionation of water, the main constituent of interstellar ices. Aims. We aim at theoretically studying the formation and the deuteration of water, which is believed to be formed on interstellar grain surfaces in molecular clouds. Methods. We used our gas-grain astrochemical model GRAINOBLE, which considers the multilayer formation of interstellar ices. We varied several input parameters to study their impact on water deuteration. We included the treatment of ortho- and para-states of key species, including H2, which affects the deuterium fractionation of all molecules. The model also includes relevant laboratory and theoretical works on the water formation and deuteration on grain surfaces. In particular, we computed the transmission probabilities of surface reactions using the Eckart model, and we considered ice photodissociation following molecular dynamics simulations. Results. The use of a multilayer approach allowed us to study the influence of various parameters on the abundance and the deuteration of water. Deuteration of water is found to be very sensitive to the ortho-to-para ratio of H2 and to the total density, but it also depends on the gas/grain temperatures and the visual extinction of the cloud. Since the deuteration is very sensitive to the physical conditions, the comparison with sub-millimetric observation towards the low-mass protostar IRAS 16293 allows us to suggest that water ice is formed together with CO2 in molecular clouds with limited density, whilst formaldehyde and methanol are mainly formed in a later phase, where the condensation becomes denser and colder.

description: We show that grand unified theories based on SO(10) generate quite naturally baryon number violating dimension seven operators that violate (B-L), and lead to novel nucleon decay modes such as n \to e^-K^+, e^- π^+ and p \to νπ^+. We find that in two-step breaking schemes of non-supersymmetric SO(10), the partial lifetimes for these modes can be within reach of experiments. The interactions responsible for these decay modes also provide a new way to understand the origin of matter in the universe via the decays of GUT scale scalar bosons of SO(10). Their (B-L)-violating nature guarantees that the GUT scale induced baryon asymmetry is not washed out by the electroweak sphaleron interactions. In minimal SO(10) models this asymmetry is closely tied to the masses of quarks, leptons and the neutrinos.

description: An electric inductor-capacitor (ELC) resonator provides a series of electrical resonances and a pair of ELC resonators leads to the split of each resonance into two modes, i.e., magnetic and electric modes, corresponding to antisymmetric and symmetric current distributions. With the meticulous design of the ELC resonator, we can achieve a negative index metamaterial through mode hybridization by overlapping the first electric resonance mode and the second magnetic resonance mode. Such non-connected designs may offer opportunities to achieve three-dimensional negative index metamaterials.

description: We have determined the frequency shift that blackbody radiation is inducing on the $5s^2$ $^1$S$_0$ -- $5s5p$ $^3$P$_0$ clock transition in strontium. Previously its uncertainty limited the uncertainty of strontium lattice clocks to $1\times10^{-16}$. Now the uncertainty associated to the black body radiation shift correction translates to $5\times 10^{-18}$ relative frequency uncertainty at room temperature. Our evaluation is based on a measurement of the differential dc-polarizability of the two clock states and on a modeling of the dynamic contribution using this value and experimental data for other atomic properties.

description: Asymptotic fields do not exist in theories with massless particles and fields, because the vacuum matrix elements of products of the interacting fields in such theories do not have delta function or principal value singularities in momentum space. We remedy this problem by constructing a field for the charged particle that does have the required singularities in momentum space. We illustrate this construction in quantum electrodynamics (QED).

Fast Point-Feature Label Placement for Dynamic Visualizations (2007)
Creators: name: Mote, Kevin
Publisher: name: arXiv
Year: 2012
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: This paper describes a fast approach to automatic point label de-confliction on interactive maps. The general Map Labeling problem is NP-hard and has been the subject of much study for decades. Computerized maps have introduced interactive zooming and panning, which has intensified the problem. Providing dynamic labels for such maps typically requires a time-consuming pre-processing phase. In the realm of visual analytics, however, the labeling of interactive maps is further complicated by the use of massive datasets laid out in arbitrary configurations, thus rendering reliance on a pre-processing phase untenable. This paper offers a method for labeling point-features on dynamic maps in real time without pre-processing. The algorithm presented is efficient, scalable, and exceptionally fast; it can label interactive charts and diagrams at speeds of multiple frames per second on maps with tens of thousands of nodes. To accomplish this, the algorithm employs a novel geometric de-confliction approach, the 'trellis strategy,' along with a unique label candidate cost analysis to determine the 'least expensive' label configuration. The speed and scalability of this approach make it well-suited for visual analytic applications.

description: In Rahmen meiner wissenschaftlichen Tätigkeit war ich in den vergangenen Jahren auf dem Gebiet der experimentellen Ästhetik tätig. Die experimentelle Ästhetik ist ein Forschungsgebiet, dessen Ursprung in den Arbeiten Gustav Theodor Fechners gegen Ende des 19. Jahrhunderts liegt. Fechner gilt als der Begründer der so genannten Psychophysik, einer Disziplin, die die Verbindung von messbaren Objekteigenschaften mit subjektiven Empfindungen untersucht (Fechner, 1876). Lag zu Fechners Zeiten allerdings der Fokus der Untersuchung noch auf einfachen mathematischen Konzepten wie dem goldenen Schnitt, werden heutzutage elaboriertere Konzepte wie Raumfrequenzen im Fourier-Spektrum, Komplexität, Anisotropie und Selbstähnlichkeit untersucht. Während der goldene Schnitt ein rein artifiziell-mathematisches Konstrukt ist, versuchen die neueren Konzepte die Bestimmung der objektiven Eigenschaften mit dem Aufbau und der Verarbeitungsweise des menschlichen visuellen Systems in Einklang zu bringen. Es besteht die Grundhypothese, dass durch diese Vorgehensweise begründet werden kann, wieso Bilder mit bestimmten objektiven Eigenschaften von Menschen präferiert werden. Meine Habilitationsschrift ist darauf ausgelegt, die aktuelle Forschungslage bezüglich der Messung von objektiven Bildeigenschaften in Kunstwerken darzulegen und hernach meine eigenen Ergebnisse zu präsentieren, die ich zusammen mit meinen Kollegen in den vergangenen Jahren innerhalb der Juniorarbeitsgruppe „Psychology of Beauty“ am Universitätsklinikum Jena erarbeitet und publiziert habe. Im folgenden Abschnitt sollen zunächst die von mir analysierten Bildeigenschaften genauer dargestellt werden. Danach wird die aktuelle Forschungslage zu globalen Bildeigenschaften in Bezug auf die Attraktivitätsbewertung von Gesichtern und die Schönheitsbewertung von (abstrakten) Kunstwerken dargelegt. Im zweiten Abschnitt werde ich dann die Ergebnisse meiner Arbeitsgruppe zusammenfassend präsentieren.

A Phase Field Crystal Study of Solute Trapping

description: In this study we have incorporated two time scales into the phase field crystal model of a binary alloy to explore different solute trapping properties as a function of crystal-melt interface velocity. With only diffusive dynamics, we demonstrate that the segregation coefficient, K as a function of velocity for a binary alloy is consistent with the model of Kaplan and Aziz where K approaches unity in the limit of infinite velocity. However, with the introduction of wave like dynamics in both the density and concentration fields, the trapping follows the kinetics proposed by S. Sobolev[Phys. Rev. A. 199:383386, 1995.], where complete trapping occurs at a finite velocity.

description: We propose a message-passing algorithm to compute the Hamiltonian expectation with respect to an appropriate class of trial wave functions for an interacting system of fermions. To this end, we connect the quantum expectations to average quantities in a classical system with both local and global interactions, which are related to the variational parameters and use the Bethe approximation to estimate the average energy within the replica-symmetric approximation. The global interactions, which are needed to obtain a good estimation of the average fermion sign, make the average energy a nonlocal function of the variational parameters. We use some heuristic minimization algorithms to find approximate ground states of the Hubbard model on random regular graphs and observe significant qualitative improvements with respect to the mean-field approximation.

description: The transport properties of the two-dimensional system in HgTe-based quantum wells containing simultaneously electrons and holes of low densities are examined. The Hall resistance, as a function of perpendicular magnetic field, reveals an unconventional behavior, different from the classical N-shaped dependence typical for bipolar systems with electron-hole asymmetry. The quantum features of magnetotransport are explained by means of numerical calculation of the Landau level spectrum based on the Kane Hamiltonian. The origin of the quantum Hall plateau σxy = 0 near the charge neutrality point is attributed to special features of Landau quantization in our system.

description: School Shootings sind relativ seltene Ereignisse, die aufgrund ihrer Grausamkeit und des Umfangs, den sie in der Berichterstattung einnehmen, dennoch als sehr präsent wahrgenommen werden. Immer öfter wird die Schuld solcher schweren Gewaltverbrechen bei den Medien gesucht und auch Journalisten berichten im Zusammenhang von School Shootings häufig von Nachahmungstaten und Copycat-Effekten. In dieser Arbeit wird der Forschungsstand zum Copycat-Effekt bei School Shootings systematisch aufgearbeitet und ein erster Überblick über den aktuellen Forschungsstand gegeben. Obwohl eine verursachende Wirkung vorheriger medial berichteter Gewalttaten in der wissenschaftlichen Literatur überwiegend bestritten wird, kann der Copycat-Effekt nicht völlig zurückgewiesen werden. So wird der Effekt der Nachahmung als ein Medieneffekt diskutiert, der sowohl die Form, das Timing, als auch die Wahrscheinlichkeit ähnlicher Taten beeinflusst. Medial berichtete Taten können demzufolge eine imitative und/oder ansteckende Wirkung haben. Während der Imitationseffekt als ein eher langfristiger, die Form des Verbrechens beeinflussender Effekt diskutiert wird, zeigt sich der Ansteckungseffekt meist als ein kurzfristiger Effekt, der sich in einer Häufung ähnlicher Verbrechen spiegelt. Individuen, die bereits über Gewaltverbrechen nachdenken, können aufgrund von Medieninhalten zu ähnlichen Taten motiviert werden. Voraussetzung für den Copycat-Effekt ist die Bekanntheit eines vorherigen ähnlichen Ereignisses und dabei spielen die Medien eine entscheidende Rolle. Auch wenn Nachahmungstaten auf Grundlage fiktiver Medieninhalte resultieren können, werden reale medial berichtete School Shootings mit größerer Wahrscheinlichkeit kopiert. Der Einfluss der Medienberichterstattung auf Copycat-Verbrechen wird in dieser Arbeit deutlich und Schlussfolgerungen und Empfehlungen für Presseagenturen zum Umgang mit Gewalttaten wie School Shootings diskutiert.

description: Дешифрирование космических снимков территории заказника «Макаровский» позволило выявить значительную пестроту спектральных яркостей, отражающих состояние растительности в его пределах. По яркостным признакам отчетливо выделились территории с различными растительными формациями: елово-пихтовыми темнохвойными лесами, каменноберезовыми лесами, зарослями кедрового стланика, долинными тополево-березово-ивовыми лесами, тундровой подгольцовой растительностью. Разнообразие геоэкологической обстановки находит отражение в пестроте рисунка растительности в пределах изображения территории с одной растительной формацией. Для сохранения биологического разнообразия на о. Сахалине рекомендуется сохранить статус ООПТ заказника, а также предпринять меры по повышению эффективности охраны природы.
description: Wildlife reserve "Makarovskiy" is a protected natural territory intended for preservation of rare and vanishing species of plants and animals. The vegetative cover of the reserve includes dark coniferous forest, mountain birch forests, jungles of cedar elfin wood, poplar-birch-willows forests of valleys, the alpine tundra belt. They represent unique vegetative communities that are necessary to be saved. Decoding of space images of "Makarovsky" has allowed revealing considerable diversity of the spectral brightness reflecting the condition of vegetation on its territory. The basic part of investigated objects has been allocated during the analysis of pictures in red and infrared zones; quantization pictures in these zones have been combined and received parities of optical density D red/D infrared for each contour. According to brightness in the red and the infrared zones territories with various vegetative formations were distinctly distinguished: dark coniferous forest, mountain birch forests and others. In images of territories with mountain taiga forest vegetation and mountain birch forests, pictures with various optical density reflecting distinctions in density of vegetation depending on geoecological conditions are allocated. It is recommended to preserve the status of wildlife reserve "Makarovskiy" on Sakhalin island, and also to take measures to increase the efficiency of wildlife management of its territory for saving biodiversity.

description: In this article we considered models of particles living in a three-dimensional space-time with a nonstandard noncommutativity induced by shifting canonical coordinates and momenta with generators of a unitary irreducible representation of the Lorentz group. The Hilbert space gets the structure of a direct product with the representation space, where we are able to construct operators which realize the algebra of Lorentz transformations. We study the modified Landau problem for both Schrödinger and Dirac particles, whose Hamiltonians are obtained through a kind of non-Abelian Bopp's shift of the dynamical variables from the ones of the usual problem in the normal space. The spectrum of these models are considered in perturbation theory, both for small and large noncommutativity parameters. We find no constraint between the parameters referring to no-commutativity in coordinates and momenta but they rather play similar roles. Since the representation space of the unitary irreducible representations SL(2,R) can be realized in terms of spaces of square-integrable functions, we conclude that these models are equivalent to quantum mechanical models of particles living in a space with an additional compact dimension.

description: Weak interaction due to gain saturation and recovery of temporal cavity solitons in a delay differential model of a long cavity semiconductor laser is studied numerically and analytically using an asymptotic approach. It is shown that apart from usual soliton repulsion leading to a harmonic mode-locking regime a soliton attraction is also possible in a laser with nonzero linewidth enhancement factor. It is shown numerically that the attraction can lead either to a soliton merging or to a pulse bound state formation.

description: Recently it has been put forward that linearly polarized gluons inside unpolarized protons affect the transverse momentum distribution of final state particles in hadronic collisions. They lead to a characteristic modulation of the differential cross section in Higgs production and to azimuthal asymmetries in, for instance, heavy quark pair production. Here we study the effect on charmonium and bottomonium production in hadronic collisions, such as at LHCb and at the proposed fixed target experiment AFTER at LHC. We focus mainly on the scalar and pseudoscalar quarkonia, eta_c, chi_{c0}, eta_b, chi_{b0}, which allow for an angular independent investigation. Within the framework of transverse momentum dependent factorization in combination with the nonrelativistic QCD based color-singlet quarkonium model, we show for small transverse momentum (q_T^2 \ll 4 M_Q^2) that the scalar and pseudoscalar quarkonium production cross sections are modified in different ways by linearly polarized gluons, while their effects on the production of higher angular momentum quarkonium states are strongly suppressed. Comparisons to chi_{c2}, chi_{b2} production can help to cancel out uncertainties. Together with the analogous study in Higgs production at LHC, quarkonium production can moreover be used to test the scale dependence of the linearly polarized gluon distribution over a large energy range.

description: Colorectal cancer is an important concern in modern society. Risk factors such as the diet indicate the need to find healthy food products displaying additional health benefits. This study aimed to characterise and evaluate the impact of the colonic metabolites from the fermented non-digestible fraction of Moringa oleifera (MO) leaves (FNFM) on cell death mechanisms from HT-29 cells. MO leaves were digested in vitro, and the 12 h-colonic extract was obtained. FNFM mainly contained morin and chlorogenic acids (41.97 and 25.33 µg/g sample). Butyric acid was ranked as the most important metabolite of FNFM. The FNFM exerted antiproliferative effect against HT-29 colorectal cancer cells (half lethal concentration, LC50: 5.9 mL/100 mL). Compared to untreated control, LC50 increased H2O2 production (149.43%); induced apoptosis (119.02%), autophagy (75.60%), and necrosis (87.72%). These results suggested that digested MO colonic metabolites exert antiproliferative effect against HT-29 cells, providing additional health benefits associated with MO consumption.

description: The Mediterranean diet (MD) has been found to lower the risk of heart disease, stroke, and diabetes in adults. Little is known about its acceptance and relationship to cardiovascular risk markers in US adolescents. Using data from the National Health and Nutrition Examination Survey, years 2007–2014, we performed a cross-sectional analysis of adherence to the Mediterranean diet among a representative sample of US adolescents (n = 4223), factors that influence adherence, and whether adherence is associated with cardiometabolic risk factors including metabolic syndrome. MD adherence was calculated using the KIDMED scoring system. We found that overall MD adherence was very low among US adolescents, with Mexican American youths having higher adherence compared to other groups. Higher income was associated with greater adherence. There was low intake of key MD foods including olive oil and finfish. The unadjusted prevalence of metabolic syndrome was 6.6%. MD adherence was not associated with metabolic syndrome.

description: We report on VERITAS very-high-energy (VHE; E>100 GeV) observations of six blazars selected from the Fermi Large Area Telescope First Source Catalog (1FGL). The gamma-ray emission from 1FGL sources was extrapolated up to the VHE band, taking gamma-ray absorption by the extragalactic background light into account. This allowed the selection of six bright, hard-spectrum blazars that were good candidate TeV emitters. Spectroscopic redshift measurements were attempted with the Keck Telescope for the targets without Sloan Digital Sky Survey (SDSS) spectroscopic data. No VHE emission is detected during the observations of the six sources described here. Corresponding TeV upper limits are presented, along with contemporaneous Fermi observations and non-concurrent Swift UVOT and XRT data. The blazar broadband spectral energy distributions (SEDs) are assembled and modeled with a single-zone synchrotron self-Compton model. The SED built for each of the six blazars show a synchrotron peak bordering between the intermediate- and high-spectrum-peak classifications, with four of the six resulting in particle-dominated emission regions.

description: Aims. We studied the characteristics of planetary nebulae (PNe) that show both OH maser and radio continuum emission (hereafter OHPNe). These have been proposed to be very young PNe, and therefore, they could be key objects for understanding the formation and evolution of PNe. Methods. We consulted the literature searching for interferometric observations of radio continuum and OH masers toward evolved stars, including the information from several surveys. We also processed radio continuum and OH maser observations toward PNe in the Very Large Array data archive. The high positional accuracy provided by interferometric observations allow us to confirm or reject the association between OH maser and radio continuum emission. Results. We found a total of six PNe that present both OH maser and radio continuum emissions, as confirmed with radio interferometric observations. These are bona fide OHPNe. The confirmed OHPNe present a bipolar morphology in resolved images of their ionized emission at different wavelengths, suggesting that the OH maser emission in PNe is related to nonspherical mass-loss phenomena. The OH maser spectra in PNe present a clear asymmetry, tending to show blueshifted emission with respect to the systemic velocity. Their infrared colors suggest that most of these objects are very young PNe. OHPNe do not form a homogeneous group, and seem to represent a variety of different evolutionary stages. We suggest that OH masers pumped in the AGB phase may disappear during the post-AGB phase, but reappear once the source becomes a PN and its radio continuum emission is amplified by the OH molecules. Therefore, OH maser emission could last significantly longer than the previously assumed 1000 yr after the end of the AGB phase. This maser lifetime may be longer in PNe with more massive central stars, which ionize a larger amount of gas in the envelope.
