description: We present results of the cross-correlation analysis between active galactic nuclei (AGNs) and galaxies at redshift 0.1-1. We obtain data of ~10,000 SDSS AGNs in which their virial masses with a super-massive black hole (SMBH) were estimated. The UKIDSS galaxy samples around the AGNs were obtained using the virtual observatory. The scale length of AGN-galaxy cross-correlation for all of the samples is measured to be r_0= 5.8+0.8-0.6 h^-1Mpc (for the fixed slope parameter γ=1.8). We also derived a dependence of r_0 on the BH mass, M_BH, and found an indication of an increasing trend of r_0 at M_BH > 10^8 Msun. It is suggested that the growth of SMBH is mainly driven by interactions with the surrounding environment for M_BH > 10^8 Msun. On the other hand, at M_BH

description: We revisit the computation of the two-loop light-like tetragonal Wilson loop for three dimensional pure Chern-Simons and N=6 Chern-Simons-matter theory, within dimensional regularization with dimensional reduction scheme. Our examination shows that, contrary to prior belief, the result respects maximal transcendentality as is the case of the four-point scattering amplitude of the theory. Remarkably, the corrected result matches exactly the scattering amplitude both in the divergent and in the finite parts, constants included.

description: We present U, V, and I-band images of the host galaxy of Hercules A (3C 348) obtained with HST/WFC3/UVIS. We find a network of dusty filaments which are more complex and extended than seen in earlier HST observations. The filaments are associated with a faint blue continuum light (possibly from young stars) and faint H-alpha emission. It seems likely that the cold gas and dust has been stripped from a companion galaxy now seen as a secondary nucleus. There are dusty filaments aligned with the base of the jets on both eastern and western sides of the galaxy. The morphology of the filaments is different on the two sides - the western filaments are fairly straight, while the eastern filaments are mainly in two loop-like structures. We suggest that despite the difference in morphologies, both sets of filaments have been entrained in a slow moving boundary layer outside the relativistic flow. As suggested by Fabian et al. (2008), magnetic fields in the filaments may stabilize them against disruption. We consider a speculative scenario to explain the relation between the radio source and the shock and cavities in the hot ICM seen in the Chandra data (Nulsen et al. 2005). We suggest the radio source originally (~60 Myr ago) propagated along a position angle of ~35 degrees where it created the shock and cavities. The radio source axis changed to its current orientation (~100 degrees) possibly due to a supermassive black hole merger and began its current epoch of activity about 20 Myr ago.

title: Musical Authenticity as ‘Being True to the Moment’
Creators: name: Bertinetto, Alessandro
Publisher: name: The Polish Journal of Aesthetics
Year: 2019

description: In this paper I argue that the specific musical authenticity of improvisation in different kinds of music (especially, but not only, in Jazz and Free improvisation practices) consists of what I call ‘being true to the moment’ and that since the artistic success of every musical performance requires performers’ attentiveness and responsiveness to the moment of the performance, improvisational authenticity is the epitome of musical authenticity. I proceed as follows. Firstly I present Peter Kivy’s plural view of musical authenticity and discuss Julian Dodd’s view of musical improvisation as essentially inauthentic. Then, I articulate two notions of improvisational authenticity, ontological and expressive authenticity, which I develop by means of a third, and crucial, notion of improvisational authenticity: truthfulness to the moment, which is the specific way improvisation realizes a fourth kind of authenticity: artistic authenticity. Finally, I argue that improvisational authenticity is paradigmatic for the authenticity of musical performance as performance.

Year: 2019

description: I examine jazz pianist Jason Moran’s conceptual artwork, Staged (2015/18), in order to interrogate the intersection between improvisation and contemporary art. Enlisting and expanding upon George Lewis’s coinage and theorization of Afrological and Eurological practices, I outline discourses that have coded improvisation as embedded in tradition, the “known,” and history, and conceptual art (as a form of “contemporary art”) as free from these. Staged brings these discourses into collision and offers new directions for contemporary art through its jazz improvisatory sensibility.

description: We analyse decoherence properties of entangled coherent states (ECSs) due to channel losses, and compare to the performance of bi-photon Bell states. By employing the concept of "entanglement of formation" (EOF), the degradation of fidelity and degree of entanglement are calculated. Two situations are considered: (1) asymmetric and (2) symmetric noise channel. In the first case, only the lower bound of EOF is given. However, in the latter case, we have obtained an explicit expression of concurrence (and then EOF) and found surprisingly our result is just incompatible with that of [Phys. Rev. A \textbf{82}, (2010) 062325] in the limit of $α\rightarrow0$. We demonstrate that entangled coherent states with sufficient small amplitudes are more robust against channel decoherence than biphoton entangled states in both cases.

description: In a semi-numerical model of reionization, the evolution of ionization fraction is simulated approximately by the ionizing photon to baryon ratio criterion. In this paper we incorporate a semi-analytical model of galaxy formation based on the Millennium II N-body simulation into the semi-numerical modeling of reionization. The semi-analytical model is used to predict the production of ionizing photons, then we use the semi-numerical method to model the reionization process. Such an approach allows more detailed modeling of the reionization, and also connects observations of galaxies at low and high redshifts to the reionization history. The galaxy formation model we use was designed to match the low-$z$ observations, and it also fits the high redshift luminosity function reasonably well, but its prediction on the star formation falls below the observed value, and we find that it also underpredicts the stellar ionizing photon production rate, hence the reionization can not be completed at $z \sim 6$ without taking into account some other potential sources of ionization photons. We also considered simple modifications of the model with more top heavy initial mass functions (IMF), with which the reionization can occur at earlier epochs. The incorporation of the semi-analytical model may also affect the topology of the HI regions during the EoR, and the neutral regions produced by our simulations with the semi-analytical model appeared less poriferous than the simple halo-based models.

Creators: name: TEWODROS MULUGETA
Publisher: name: Zenodo
Year: 2019

description: Background: - World Health Organization defined birth asphyxia as the failure to initiate and sustain breathing at birth. Globally, 23% of neonatal mortality occurs due to birth asphyxia and in Ethiopia, 31.6% of neonatal mortality occurs due to birth asphyxia. The effect of birth asphyxia is not limited only to death but also has a short and long term neurodevelopment sequel, including cognitive and motor disabilities which are almost untreatable.

Objective: - The objective of this study was to assess risk factors of birth asphyxia among newborns delivered at public hospitals of Addis Ababa, Ethiopia, 2019.

Methods: Institutional based unmatched case-control study was conducted with a total sample size of 213 (71 cases and 142 controls) in Addis Ababa public hospitals from March 1–April 30, 2019. Cases were selected consecutively using consecutive sampling technique and controls were selected by systematic random sampling method. Data was collected using structured questionnaire through face to face interview with index mothers, measurements and chart record review using checklist. The collected data was entered to Epi data version 4.4 and exported to SPSS version 25 for analysis. Finally, it was analyzed by binary logistic regression model. Variables with (p< 0.25) in bivariate analysis were entered to multivariable logistic regression. Statistical significance was declared at P<0.05.

description: Precise navigation and geodetic coordinate determination rely on accurate GNSS signal reception. Thus, the receiver antenna properties play a crucial role in the GNSS error budget. For carrier phase observations, a spherical radiation pattern represents an ideal receiver antenna behaviour. Deviations are known as phase centre corrections. Due to synergy of carrier and code phase, similar effects on the code exist named code phase variations (CPV). They are mainly attributed to electromagnetic interactions of several active and passive elements of the receiver antenna. Consequently, a calibration and estimation strategy is necessary to determine the shape and magnitudes of the CPV. Such a concept was proposed, implemented and tested at the Institut für Erdmessung. The applied methodology and the obtained results are reported and discussed in this paper.We show that the azimuthal and elevation-dependent CPV can reach maximum magnitudes of 0.2–0.3m for geodetic antennas and up to maximum values of 1.8m for small navigation antennas. The obtained values are validated by dedicated tests in the observation and coordinate domain. As a result, CPV are identified to be antenna- related properties that are independent from location and time of calibration. Even for geodetic antennas when forming linear combinations the CPV effect can be amplified to values of 0.4–0.6 m. Thus, a significant fractional of theMelbourne–Wübbena linear combination. A case study highlights that incorrect ambiguity resolution can occur due to neglecting CPV corrections. The impact on the coordinates whichmay reach up to the dmlevel is illustrated.

description: Mapping and assessment of ecosystems and their services (MAES) is a key EU initiative to synthesise vital environmental information and facilitate balanced policy decisions. As MAES integrates across many scientific and policy domains, the development of a common language and shared concepts is essential. Here we present a comprehensive MAES Glossary that was compiled in the ESMERALDA project; it is based on the integration of several previous glossaries and a wide-ranging consultation process. While there are several ecosystem services glossaries available from EU supported work such as Oppla, OpenNESS and ecosystem services related handbooks, the new material presented here focuses on mapping and assessment of ecosystem services and therefore more directly supports the MAES process.
The Observable Thermal and Kinetic Sunyaev-Zel'dovich Effect in Merging Galaxy Clusters

description: The advent of high-resolution imaging of galaxy clusters using the Sunyaev-Zel'dovich Effect (SZE) provides a unique probe of the astrophysics of the intracluster medium (ICM) out to high redshifts. To investigate the effects of cluster mergers on resolved SZE images, we present a high-resolution cosmological simulation of a 1.5E15 M_sun adiabatic cluster using the TreeSPH code ChaNGa. This massive cluster undergoes a 10:3:1 ratio triple merger accompanied by a dramatic rise in its integrated Compton-Y, peaking at z = 0.05. By modeling the thermal SZE (tSZ) and kinetic SZE (kSZ) spectral distortions of the Cosmic Microwave Background (CMB) at this redshift with relativistic corrections, we produce various mock images of the cluster at frequencies and resolutions achievable with current high-resolution SZE instruments. The two gravitationally-bound merging subclusters account for 10% and 1% of the main cluster's integrated Compton-Y, and have extended merger shock features in the background ICM visible in our mock images. We show that along certain projections and at specific frequencies, the kSZ CMB intensity distortion can dominate over the tSZ due to the large line of sight velocities of the subcluster gas and the unique frequency-dependence of these effects. We estimate that a one-velocity assumption in estimation of line of sight velocities of the merging subclusters from the kSZ induces a bias of ~10%. This velocity bias is small relative to other sources of uncertainty in observations, partially due to helpful bulk motions in the background ICM induced by the merger. Our results show that high-resolution SZE observations, which have recently detected strong kSZ signals in subclusters of merging systems, can robustly probe the dynamical as well as the thermal state of the ICM.

description: A dependence of the formation of tri-n-octylphosphine-capped Ni nanocrystals on the presence of halide ions during their synthesis is shown. For the application-oriented synthesis of Ni particles, this information can be crucial. Furthermore, Ni nanoparticles can be converted to nickel phosphide or sulphide by heating them up in the presence of a phosphorus or sulphur source, resulting in either solid or hollow nanocrystals, formed via the nanoscale Kirkendall effect, depending on the synthesis route. By adjusting the Ni crystallite size in the initial nanoparticles via the halide ion concentration the cavity size of the resulting hollow nanocrystals can be tuned, which is otherwise impossible to realise for particles of a similar total diameter by using this process. The synthesised hollow Ni3S2 nanocrystals exhibit a much sharper localised surface plasmon resonance (LSPR) band than all previously presented particles of this material, which is known to show molar extinction coefficients at the LSPR maximum similar to Au. This narrow linewidth could be explained by the nanoparticles’ high crystallinity resulting from the Kirkendall process and is interesting for various possible optical applications such as surface-enhanced Raman spectroscopy owing to the low cost of the involved materials compared to the widely used noble metals.

description: Purpose: This paper aims to represent a unique and original piece of research on full professors in global hospitality and tourism academia. Aimed at revisiting academic leadership, this study identifies its components and gains insight into the so far understudied dimensions of diversity in academic contexts worldwide. Design/methodology/approach: This study examines the careers of senior researchers (R3 and R4, according to European Commission) in hospitality and tourism, with special attention given to diversity. Based on quantitative methodology and a standardised online search, it uses individual-level data to give insights into dimensions of academic leadership. Full professors from the UK, the USA, German-speaking countries (Germany, Austria and Switzerland) and the Asia-Pacific region (Australia, New Zealand, China, Malaysia, Singapore and South Korea) build the sample. Findings: Academic leadership in hospitality and tourism academia is not yet fully tied to cooperation with industry, as predicted by the “Triple Helix” model. Currently, the majority of the intellectual component constitutes academic leadership, outweighing administrative and innovative angles. Gender, age and ethnic diversity are underrepresented. While some regions can be considered sealed to ethnic diversity, others are more open and attract international scholars. Originality/value: Rooted in interdisciplinary explanations, this study is the first of its kind to consider various diversity dimensions of academic leadership from a global perspective. It not only enriches the notion of academic leadership but also provides several practical implications and suggestions for further research.

description: While operating under different names, both Europe and Russia are currently going through a period of social change in academia. Europe is pursuing reforms and transformation of academia in the context of the New Public Management, while Russia operates in similar settings of modernization, thus addressing excellence and effectiveness of academic work. In both cases, the processes underlying social change in academia result in a similar impact on female scholars' occupational advancement. By doing so, they reproduce the existing gender inequalities and create new ones. Russia finds itself in a paradoxical situation: while women represent the majority of (scientific) staff in academia, they face persistent discrimination at the hands of their colleagues - both male and female. Still, our knowledge of gender disparities and discrimination in Russian academia is fragmented and needs extensive investigation. In order to establish the necessary foundation for further systematic analysis, this paper aims to reduce the existing gap by examining gender inequalities from a historical perspective.

description: High-resolution rainfall data are needed in many fields of hydrology and water resources management. For analyzes of future rainfall condition climate scenarios exist with hourly values of rainfall. However, the direct usage of these data is associated with uncertainties which can be indicated by comparisons of observations and C20 control runs. An alternative is the derivation of changes of rainfall behavior over the time from climate simulations. Conclusions about future rainfall conditions can be drawn by adding these changes to observed time series. A multiplicative cascade model is used in this investigation for the disaggregation of daily rainfall amounts to hourly values. Model parameters can be estimated by REMO rainfall time series (UBA-, BfG- and ENSrealization), based on ECHAM5. Parameter estimation is carried out for C20 period as well as near term and long term future (2021-2050 and 2071-2100). Change factors for both future periods are derived by parameter comparisons and added to the parameters estimated from observed time series. This enables the generation of hourly rainfall time series from observed daily values with respect to future changes. The investigation is carried out for rain gauges in Lower Saxony. Generated Time series are analyzed regarding statistical characteristics, e.g. extreme values, event-based (wet spell duration and amounts, dry spell duration, . . . ) and continuum characteristics (average intensity, fraction of dry intervals,. . . ). The generation of the time series is validated by comparing the changes in the statistical characteristics from the REMO data and from the disaggregated data.

Reaction rate constants were determined in the range of collision energies /k_B = 20 mK-20 K. The lowest energies were achieved in experiments using single localized Ca^+ ions. Product branching ratios were studied using resonant-excitation mass spectrometry. The dynamics of the reactive processes in this system (non-radiative and radiative charge transfer as well as radiative association leading to the formation of CaRb^+ molecular ions) have been analyzed using high-level quantum-chemical calculations of the potential energy curves of CaRb^+ and quantum-scattering calculations for the radiative channels. For the present low-energy scattering experiments, it is shown that the energy dependence of the reaction rate constants is governed by long-range interactions in line with the classical Langevin model, but their magnitude is determined by short-range non-adiabatic and radiative couplings which only weakly depend on the asymptotic energy. The quantum character of the collisions is predicted to manifest itself in the occurrence of narrow shape resonances at well-defined collision energies. The present results highlight both universal and system-specific phenomena in cold ion-neutral reactive collisions.

description: In this contribution, the in-house (processed) GOCE products including precise orbit and Earth’s gravity field are compared to the official ESA products. The comparison is drawn on orbit product as well as gravity field level. To ensure comparability, gravity field models from both orbits are estimated in an identical fashion,whichisparticularlytrueforthestochasticalmodel.Wefindthatthein-house processed orbit is piecewise rather smooth, but contains jumps like discontinuities in the calculated geometrical point-wise positions. This leads to a degradation of the gravity field solution about by a factor of two in terms of degree variances when compared to the solution from the official orbit product.

description: High-low GPS LEO (Low Earth Orbiter) SST (Satellite to Satellite Tracking) observations play an important role to determine geometrical, precise, 3D orbits of LEO satellites. The ambiguity parameters in the Zero difference technique aren’t integer any more, and the carrier phase observations have to be solved in the float mode. If the difference between two sequential epochs has been built, and the observation rate is small then on the one hand, the ambiguity parameters have been canceled out (if there aren’t any cycle slips in the carrier phase observations), on the other hand many errors in the ZD observations can be eliminated (e.g. antenna phase centre offsets and its variations, multi-path, etc.). Therefore, the sequential time differenced carrier phase observation has been proven to be very efficient for the LEO precise orbit determination. In this paper, as a first step to determine geometrical LEO precise orbits, initial LEO absolute positions have been estimated based on the Bancroft method with an accuracy of a few meters. These absolute positions can be used subsequently as initial values for LEO positions based on pseudo-range ionosphere free observations. To avoid cycle slips in the carrier phase observations, at first, 15 elevation cut-off angle has been applied to the observations, secondly, with the estimated positions in the code pseudo-range process and with the help of the receiver clock offset between two sequential epochs, the cycle slips have been eliminated in the iterative process. It is clear that in this method, the estimated LEO orbit is point-wise (geometrical, not kinematical) and the geometrical configuration (DOP) of GPS satellites plays an important roll in the data processing.

description: The elusive nature and the function of art occupy a highly contested territory within aesthetic philosophy since its inception. The present article also engages with the question of the nature and the function of art, though in a more narrowed and specific domain. The claim that is going to be tackled here is whether improvisation in art, in general, makes a statement against empirical science? To corroborate this claim I will look at specific artworks that offer a way of considering the function of art as something that can stand in opposition to empirical science and as something that therefore can offer an alternative understanding of consciousness. The main question is, “where does improvisation stand against the radical evolutionary positivist objectivization of consciousness?” To answer, we look at the emancipatory role of art that challenges the empiricism of modern science via investigating several artworks as signposts. We examine different types of improvisation by analyzing Joe Wight’s Darkest Hour (2017) and by drawing on the concept of autopoiesis, we define autopoietic improvisation as free improvisation. Then we draw on Charlie Brooker’s Black Mirror show (2011–present) to indicate that the idea of how indelible techno-totalitarianism, which envisages a dystopian future for mankind via the refinement and regulation of consciousness, offers a limited view of consciousness. Techno-totalitarianism stands as a key term to be defined and analyzed here as it is precisely the mechanism against and through which I will shape a new discourse of improvisation. Techno-totalitarianism is the state of digital rationalization and instrumentation of neuroscience in the regulation of human desire, choice, and behavior such as regulation and self-regulation are no longer distinguishable. We also discuss how finding a theory of everything and complete formula for consciousness means cutting new alleyways to utter annihilation of human will, improvisation or freedom in general. Keywords Anti-representational Art, Neuroscience, Improvisation, Self-objectivization, Consciousness, Technototalitarianism, Autopoiesis

description: The geometrical point-wise Low Earth Orbiters (LEO) positions can be derived by Global Navigation Satellite System (GNSS) analysis techniques. The different precise point positioning techniques based on GNSS observations will be designated as Geometrical Precise Orbit Determination (GPOD) methods. In the geometrical determined LEO orbit, there is no connection between subsequent absolute positions, and consequently, no information about the velocity or even the acceleration (or in general kinematical information) of the satellite is available. To describe the time dependency of the motion of a satellite, it is necessary to provide a properly constructed function which consistently connects positions, velocities and accelerations. In this investigation, a new approach is presented based on approximation parameters, which have also a clearly defined relation to the dynamical model of the satellite's motion. If the kinematical parameters are determined by a best fitting process based on the GNSS observations, then we perform a pure Kinematical Precise Orbit Determination (KPOD). The geometrical and kinematical precise orbit of Gravity field and steady-state Ocean Circulation Explorer (GOCE) based on real high-low Satellite to Satellite Tracking (hl-SST) GNSS observations will be presented.

description: With GOCE, for the first time in history, a Gravity Gradiometer has been used in space to recover the Earth’s gravity field. Based on the gravity gradiometer observations, the short wavelength part of the Earth gravity field can be determined accurately. The lower frequency part (i.e. the long wavelength) of the Earth gravity field can be extracted from high-low Satellite to Satellite Tracking (hl-SST) data which are observed by the GNSS receiver onboard GOCE. Based on the high-low SST observations, kinematical precise orbit of GOCE can be determined. The kinematical precise orbit of GOCE, which either is estimated with an in-house developed software or supplied as the precise science orbit (PSO) by the European Space Agency (ESA), are used to estimate the Earth gravity field. The physical model of the applied gravity field recovery technique is based on Newton’s equation of motion, formulated as a boundary value problem in the form of a Fredholm's type integral equation. In this paper, the precise orbit product of the GOCE will be validated and the amount of gravity field information within the different orbit products will be compared in a validation step.
