description: A recent report on gravitational wave detector data from the NAUTILUS and EXPLORER detector groups claims a statistically significant excess of coincident events when the detectors are oriented in a way that maximizes their sensitivity to gravitational wave sources in the galactic plane. While not claiming a detection of gravitational waves, they do strongly suggest that the origin of the excess is of gravitational wave origin. In this note we show that the statistical analysis that led them to the conclusion that there is a statistical excess is flawed and that the reported observation is entirely consistent with the normal Poisson statistics of the reported detector background.

description: Multidentate 1,3,5-benzene tricarboxylic acid copolymerizes with Zinc to form framework with rigid porosity for gas adsorption application. One of the barriers in commercialization of these MOFs for gas adsorption application is the usage of costly solvents and this research is based on identifying the effect of solvents on zinc and 1,3,5-benzene tricarboxylic acid-based MOFs, their gas adsorption capacities and costs. All the MOFs prepared were characterized and further tested for carbon dioxide adsorption capacities. The results highlight that the textural properties of prepared MOFs depend largely on solvents utilized and high surface area MOFs have high adsorption capacity. Also the carbon dioxide adsorption capacity of MOFs prepared using DMF showed better adsorption as compared with the one prepared with Ethanol:De-ionized water. This research also elaborates the fact that there is a possibility of replacing the expensive solvents for Zn-BTCs synthesis with low-cost solvents without compromising the gas adsorption performance.
An X-Ray Detection Possibility of Star-Formation-Bursting Proto-Elliptical Galaxies

description: A possibility to detect X-rays from star-formation burst activities in proto-elliptical galaxies is considered. The X-ray flux of an emission due to inverse Compton scattering of the cosmic microwave background (CMB) by high energy electrons accelerated in SNRs is shown to increase as z increases far beyond unity, since the local CMB flux largely increases in association with a z-increase. The flux is estimated for the case of a very high rate of type II supernovae at an initial star formation burst of a proto-elliptical galaxy and is found to be detectable with a future large X-ray telescope such as intended in the XEUS mission.

Viscous Evolution of Magnetized Clumps: a Source for X-ray Flares in Gamma-ray Bursts

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: X-ray flares can be accounted for a hint to the late time activity of Gamma-ray bursts (GRBs) central engines. Such a long term activity has been described through some models, one of which is the viscous evolution of the outer disc fragments that proposed by Perna et al. (2006), and developed quantitatively by Dall Osso et al. (2017). Here, we reconstruct Dall Osso et al. (2017) framework through taking both small and large scale effects of magnetic field into account. To consider the magnetic barrier as a possible mechanism that might govern the accretion process of each magnetized clump, we make a simple pattern in boundary condition through which this mechanism might happen. Regarding various model parameters, we probe for their influence and proceed some key analogies between our model predictions and previous phenomenological estimates, for two different choices of boundary conditions (with and without a magnetic barrier). Our model is remarkably capable of matching flare bolometric and X-ray light-curves, as well as reproducing their statistical properties, such as the ratios between rise and decay time, width parameter and peak time, and the power-law correlation between peak luminosity and peak time. Combining our results with the conclusions of previous studies, we are led to interpret magnetic barrier as a less probable mechanism that might control the evolution of these clumps, especially the later created (or viscously evolved) ones.

description: In the Netherlands, there are several PID services embedded in specific use cases. Each (see below) operates independently from the others with a low level of coordination between them. SURF is presently planning a national working group to increase PID coordination and provide a venue for a PID advisory board. This board would be tasked with maintaining a current account of Dutch PID priorities, while remaining agile in the face of national and international developments. An important recent step towards a national PID roadmap is the NWO/SURF co-development of a PID strategy for the Dutch Research Council (national research funder). Development towards a national PID roadmap coincides with broader interest in open infrastructures. Of particular relevance to PID activities in The Netherlands is ongoing exploration of a Netherlands Open Knowledge Base (NL OKB).

description: Spitzer's final Infrared Array Camera (IRAC) observations of SN 1987A show the 3.6 and 4.5 $μ$m emission from the equatorial ring (ER) continues a period of steady decline. Deconvolution of the images reveals that the emission is dominated by the ring, not the ejecta, and is brightest on the west side. Decomposition of the marginally resolved emission also confirms this, and shows that the west side of the ER has been brightening relative to the other portions of the ER. The infrared (IR) morphological changes resemble those seen in both the soft X-ray emission and the optical emission. The integrated ER light curves at 3.6 and 4.5 $μ$m are more similar to the optical light curves than the soft X-ray light curve, though differences would be expected if dust is responsible for this emission and its destruction is rapid. Future observations with the James Webb Space Telescope will continue to monitor the ER evolution, and will reveal the true spectrum and nature of the material responsible for the broadband emission at 3.6 and 4.5 $μ$m. The present observations also serendipitously reveal a nearby variable source, subsequently identified as a Be star, that has gone through a multi-year outburst during the course of these observations.

description: The African Penguin Spheniscus demersus is an endangered seabird endemic to southern Africa, and killing sprees by terrestrial predators have been one of the main threats for its mainland colonies. The methods employed to manage predators may differ depending on the species involved, therefore the implementation of strategies to limit the impacts of predation relies on the correct identification of the culprit predator. We report and quantify the lesions seen in African Penguins killed by four species of terrestrial predators: Caracal Caracal caracal (52 kills), Leopard Panthera pardus (27 kills), Domestic Dog Canis lupus familiaris (10 kills), and Cape Grey Mongoose Galerella pulverulenta (4 kills). We discuss patterns of necropsy findings that can be used to identify the predator species involved. Traditional forensic methods are useful tools to direct species-specific management actions for the conservation of the African Penguin and other seabirds so that effective mitigating measures can be deployed quickly to prevent further losses. It should be borne in mind, however, that the age, size and previous hunting experience of the predator are likely to influence the pattern of lesions that will be observed, and not all carcasses will have hallmark lesions or recognisable bite marks.

description: We examine the generation of gravity waves by the surface convection zone of low-mass main sequence stars with solar metallicity. It is found that the total momentum luminosity in waves rises with stellar mass, up to the quasi-disappearance of the convection zone around 6500K (corresponding to a mass of about 1.4 Msun for solar metallicity) where the luminosity drastically drops. We calculate the net momentum extraction associated with these waves and explain how the calculated mass dependence helps resolve the enigma of the Li dip in terms of rotational mixing, forming a coherent picture of mixing in all main sequence stars.

description: We present the discovery of a dusty quasar, SMMJ04135+10277, located behind the galaxy cluster Abell 478. The quasar was discovered as the brightest source in a submillimetre survey of high redshift galaxies lensed by foreground rich clusters of galaxies in a project aimed at studying the cosmic star formation history of dusty galaxies. With submm fluxes of S_850 = 25+-2.8 mJy and S_450 = 55+-17 mJy this object is one of the brightest submillimetre sources known. Optical observations revealed a quasar with redshift z=2.837. The quasar was also detected at shorter infrared wavelengths with the Infrared Space Observatory. This object is the first quasar discovered by its submm emission. Given the general lack of overlap between deep submm and X-ray samples, usually interpreted as a low incidence of active nuclei in submm samples, this is an unusual object. Analysis of number counts of quasars and of submm galaxies bears out this suggestion. We compare the properties of SMMJ04135+10277 to those of optically selected quasars with submm emission, and argue that the optical faintness results from a large viewing angle with the direction of relativistic beaming, and not from abnormally high extinction. We also find indications that the bulk of the submm flux density is not powered by the quasar nucleus. This conclusion is supported by analysis of the infrared spectral energy distribution. These results are consistent with previous observations that quasars at higher redshift tend to have a more prominent cold dust component, most likely powered by extended star formation in the host galaxy. The quasar is found to have a total infrared luminosity of (2.9+-0.5)x10^13 L_sun, dominated by the emission from cool dust. (Abridged)

description: The study of Cosmic Microwave Background (CMB) anisotropies represents one of the most powerful Cosmological tools. After the great success of the two NASA's satellite missions COBE and WMAP, Planck represents the third generation of mm-wave instruments designed for space observations of CMB anisotropies within the new Cosmic Vision 2020 ESA Science Programme. The Planck survey will cover the whole sky with unprecedented sensitivity, angular resolution and frequency coverage, using two instruments that share the focal region of a 1.5 m off-axis dual reflector telescope: the Low Frequency Instrument (LFI) and the High Frequency Instrument (HFI). Within the LFI optical interfaces optimisation activity, two concurrent demands have to be satisfied: the best angular resolution (which impacts the ability to reconstruct the anisotropy power spectrum of the CMB anisotropies at high multipoles) and the lowest level of straylight contamination (that may be one of the most critical sources of systematic effects). We present the results of the optical simulations aimed to establish the trade-off between angular resolution and straylight rejection, carried out for the 100 GHz channel of Planck Low Frequency Instrument. Antenna pattern of different models of dual profiled corrugated conical feed horns have been simulated using advanced simulation techniques, considering the whole spacecraft geometry in order to obtain truthful sidelobe predictions. Optical computation accuracy necessary to provide strong straylight evaluation in reasonable computational time is shown and the inadequacy of a Gaussian feed model in realistic far pattern predictions is demonstrated. This paper is based on LFI activities.

Based on symmetry considerations we ask for those forces which are able to compensate the imprint of the gravitational wave on the macroscopic 4-acceleration of the gaseous fluid. We establish an exactly solvable toy model according to which the stationary states which characterize such a situation have negative entropy production and are accompanied by instabilities of the microscopic particle motion. These features are similar to those which one encounters in phenomena of self-organization in many-particle systems.

description: The goal of this paper is to express the Bach tensor of a four dimensional conformal geometry of an arbitrary signature by the Cartan normal conformal (CNC) connection. We show that the Bach tensor can be identified with the Yang-Mills current of the connection. It follows from that result that a conformal geometry whose CNC connection is reducible in an appropriate way has a degenerate Bach tensor. As an example we study the case of a CNC connection which admits a twisting covariantly constant twistor field. This class of conformal geometries of this property is known as given by the Fefferman metric tensors. We use our result to calculate the Bach tensor of an arbitrary Fefferman metric and show it is proportional to the tensorial square of the four-fold eigenvector of the Weyl tensor. Finally, we solve the Yang-Mills equations imposed on the CNC connection for all the homogeneous Fefferman metrics. The only solution is the Nurowski-Plebanski metric.

description: We present the multi-wavelength identifications for 23 sources in the Canada-UK Deep Submillimeter Survey (CUDSS) 14h field. The identifications have been selected on the basis of radio and near-infrared data and we argue that, to our observational limits, both are effective at selecting the correct counterparts of the SCUBA sources. We discuss the properties of these identifications and find that they are very red in near-infrared color, with many classified as Extremely Red Objects, and show disturbed morphologies. Using the entire CUDSS catalogue of 50 sources we use a combination of spectroscopic redshifts (4 objects), 1.4GHz-to-850um flux ratio redshift estimates (10 objects), and redshift lower-limits based on non-detections at 1.4GHz (the rest of the sample) to estimate a lower-limit on the median redshift of the population of z_med > 1.4. Working from simple models and using the properties of the secure identifications, we discuss general and tentative constraints on the redshift distribution and the expected colors and magnitudes of the entire population.

Vulnerable Window of Yield Strength for Swelling-Driven Fracture of Phase-Transforming Battery Materials

description: Despite numerous experimental and theoretical investigations of the mechanical behavior of high-capacity Si and Ge Li-ion battery anodes, our basic understanding of swelling-driven fracture in these materials remains limited. Existing theoretical studies have provided insights into elasto-plastic deformations caused by large volume change phase transformations, but have not modeled fracture explicitly beyond Griffith's criterion. Here we use a multi-physics phase-field approach to model self-consistently anisotropic phase transformation, elasto-plastic deformation, and crack initiation and propagation during lithiation of Si nanopillars. Our results reveal the existence of a vulnerable window of yield strength inside which pillars fracture during lithiation. They identify two different modes of fracture inside that window with and without surface localization of plastic deformation prior to fracture for lower and higher yield strength, respectively, and highlight the importance of taking into account this localization to accurately predict the onset of fracture within Griffith theory. The results further demonstrate how the increased robustness of hollow nanopillars can be understood as a direct effect of anode geometry on the size of this vulnerable window. Those insights provide an improved theoretical basis for designing mechanically stable phase-transforming battery materials undergoing large volume changes.

description: Motivated by the research interests on realizing flat bands and magnetization plateaus in kagome lattices, we study the electronic properties and magnetic interactions in both zero- and one-dimensional triangular Kagome lattice (1D-TKL) models, by using the real-space Greens function approach in tight-binding model. We firstly study the electronic properties of both 0D and 1D-TKL in the presence of staggered sublattice potential, then, by analyzing the Ruderman-Kittel-Kasuya-Yoshida (RKKY) interaction in these lattice structures, the magnetic ground states of both 0D and 1D-TKL in the presence of two magnetic adatoms are evaluated. It is found that the 1D channels of TKL show different electronic and magnetic behaviors due to different values of the hopping integrals and spin-orbit couplings. Two important salient features of these TKLs are the presence of flat bands in their band structure as well as the emergence of the RKKY plateaus versus the Fermi energy. These RKKY plateaus have not been reported before, to the best of our knowledge. The most remarkable observation is the potential and Fermi energy variation of the width and location of the RKKY plateaus in both 0D and 1D TKLs. The spatial configurations of the magnetic impurities can also dramatically change the quality and quantity of the RKKY plateaus. We believe that our results provide significant insights towards designing further experiments to search for the realizing of the flat bands and magnetization plateau phases in spintronics and pseudospin electronics devices based on TKLs.

Astrometric planet search around southern ultracool dwarfs IV. Relative motion of the FORS2/VLT CCD chips

description: We present an investigation of the stability of the two chips in the FORS2 camera CCD mosaic on the basis of astrometric observations of stars in 20 sky fields, some of which were monitored for four to seven years. We detected a smooth relative shear motion of the chips along their dividing line that is well approximated by a cubic function of time with an amplitude that reaches ~0.3 pixels (px) or ~38 mas over seven years. In a single case, we detected a step change of ~0.06 px that occurred within four days. In the orthogonal direction that corresponds to the separation between the chips, the motion is a factor of 5-10 smaller. This chip instability in the camera significantly reduces the astrometric precision when the reduction uses reference stars located in both chips, and the effect is not accounted for explicitly. We found that the instability introduces a bias in stellar positions with an amplitude that increases with the observation time span. When our reduction methods and FORS2 images are used, it affects stellar positions like an excess random noise with an RMS of ~0.5 mas for a time span of three to seven years when left uncorrected. We demonstrate that an additional calibration step can adequately mitigate this and restore an astrometric accuracy of 0.12 mas, which is essential to achieve the goals of our planet-search program. These results indicate that similar instabilities could critically affect the astrometric performance of other large ground-based telescopes and extremely large telescopes that are equipped with large-format multi-chip detectors if no precautions are taken.

Entanglement entropy of physical states in hypercuboidally truncated spin foam quantum gravity
Creators: name: Bahr, Benjamin
Publisher: name: arXiv
Year: 2019
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this article we consider physical states in the hypercuboidal truncation of the EPRL-FK spin foam quantum gravity model. In particular, these states are defined on graphs which allow considering the entanglement entropy (EE) associated to the bipartition of space. We compute the EE numerically for some examples, and find that it depends on the coupling constants within the theory. We also find that there appears a maximum of the EE within the region of the coupling constant containing the non-Gaussian fixed point of the RG flow of the truncated model. We discuss the relation of this behaviour with the restoration of diffeomorphism symmetry at the fixed point.

An experimental study of heat transfer to flowing granular media
Creators: name: Spelt, Jan Karel
Publisher: name: California Institute of Technology

Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: The convective heat transfer to a flowing, cohesionless granular material has been studied experimentally. Heat-transfer rates were measured for two materials from a heated plate installed in the floor of an inclined, open chute. The variable parameters were the bed depth and the mass flow rate.

At relatively small flow rates the heat-transfer rate increased	with velocity in agreement with earlier studies. As the mass flow rate continued to rise however, it was discovered that the heat-transfer coefficient for a given bed depth reached a maximum and then decreased.

description: We present new UV spectra of the nucleus of the Seyfert 1 galaxy NGC 5548, which we obtained with the Space Telescope Imaging Spectrograph at high spectral resolution, in conjunction with simultaneous Chandra X-ray Observatory spectra. Taking advantage of the low UV continuum and broad emission-line fluxes, we have determined that the deepest UV absorption component covers at least a portion of the inner, high-ionization narrow-line region (NLR). We find nonunity covering factors in the cores of several kinematic components, which increase the column density measurements of N V and C IV by factors of 1.2 to 1.9 over the full-covering case; however, the revised columns have only a minor effect on the parameters derived from our photoionization models. For the first time, we have simultaneous N V and C IV columns for component 1 (at -1040 km/s), and find that this component cannot be an X-ray warm absorber, contrary to our previous claim based on nonsimultaneous observations. We find that models of the absorbers based on solar abundances severely overpredict the O VI columns previously obtained with the Far Ultraviolet Spectrograph, and present arguments that this is not likely due to variability. However, models that include either enhanced nitrogen (twice solar) or dust, with strong depletion of carbon in either case, are successful in matching all of the observed ionic columns. These models result in substantially lower ionization parameters and total column densities compared to dust-free solar-abundance models, and produce little O VII or O VIII, indicating that none of the UV absorbers are X-ray warm absorbers.

description: We propose the concept of the time-independent correlators for the even- and odd-frequency pairing states that can be defined for both bosonic and fermionic quasiparticles. These correlators explicitly capture the existence of two distinct classes of pairing states and provide a direct probe of the hidden Berezinskii order. This concept is illustrated in the cases of pairings for Majorana fermions and quasiparticles in Dirac semimetals. It is shown that the time-independent correlator is able to effectively capture the energy scale relevant for pairing.

Calculation of wave characteristics in bubbly two-phase flows
Creators: name: Wong, Tak-Yiu

Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Kinematic and dynamic wave characteristics in bubbly two-phase flows are investigated. Using the same set of basic equations, kinematic and dynamic wave characteristics in a one-dimensional flow system were simultaneously obtained. A simple linear model was used so that the response of the flow to oscillatory perturbations of frequency [Omega] was studied. Explicit asymptotic solutions for the wave speeds and attenuations in various relative velocity and frequency regimes were obtained. Numerical analyses were carried out to investigate intermediate or transitional values of the parameters. The regimes of validity for a number of conventional wave propagation models (drift-flux model and acoustic wave analysis) were explored by using the present results. It was observed that for most engineering bubbly two-phase flows of concern, the inertial effects, which are commonly neglected in many existing models, should be included for better accuracy in prediction of wave characteristics.

description: TorchGAN is a PyTorch based framework for writing succinct and comprehensible code for training and evaluation of Generative Adversarial Networks. The framework's modular design allows effortless customization of the model architecture, loss functions, training paradigms, and evaluation metrics. The key features of TorchGAN are its extensibility, built-in support for a large number of popular models, losses and evaluation metrics, and zero overhead compared to vanilla PyTorch. By using the framework to implement several popular GAN models, we demonstrate its extensibility and ease of use. We also benchmark the training time of our framework for said models against the corresponding baseline PyTorch implementations and observe that TorchGAN's features bear almost zero overhead.

description: Ο ιός του Δυτικού Νείλου(ΙΔΝ) έκανε την εμφάνιση του, για πρώτη φορά, στην Ελλάδα το 2010. Πρόκειται για έναν φλαβοϊό ο οποίος μπορεί να προκαλέσει λοίμωξη, εκτός από ορισμένα ζώα (πτηνά, ιπποειδή) , και στον ανθρώπινο οργανισμό. Η μετάδοση της νόσου συμβαίνει μέσω δείγματος μολυσμένου από τον ιό του Δυτικού Νείλου κουνουπιού στον άνθρωπο, κυρίως του γένους Culex spp. Οι κλινικές εκδηλώσεις αφορούν σημάδια όπως πυρετό, πονοκεφάλους, πόνο στο σώμα, ναυτίες και εμετούς ενώ πιο έντονα συμπτώματα όπως υψηλός πυρετός, μυϊκή αδυναμία κ.λπ. εκδηλώνονται όταν πρόκειται για σοβαρή μορφή της νόσου του ιού Δυτικού Νείλου. Σκοπός της διπλωματικής μελέτης είναι ο εντοπισμός και η καταγραφή της δραστηριότητας του ΙΔΝ στην Ελλάδα από την πρώτη εμφάνιση του μέχρι και σήμερα. Τα δεδομένα βασίζονται στην διαθέσιμη βιβλιογραφία και παρουσιάζονται με χρονολογική σειρά. Συμπεριλαμβάνονται στοιχεία σχετικά με την προέλευση, την οικολογία, τις μεθόδους διάγνωσης και θεραπείας του ΙΔΝ, παρουσίαση του σχεδίου επιδημιολογικής επιτήρησης καθώς και των μέτρων προστασίας, όπως αυτά εφαρμόζονται στην Ελλάδα. Έχουν σημειωθεί καθ΄ όλη την διάρκεια της παρουσίας του ιού του Δυτικού Νείλου στην χώρα, επιδημιολογικά ξεσπάσματα τα οποία χαρακτηρίζονται από ορισμένες χρονολογίες περιστασιακά, σε διάφορες γεωγραφικές περιοχές και δεν αποκλείουν το ενδεχόμενο επανεμφάνισης μιας τέτοιας κατάστασης στο παρόν ή και στο μέλλον. Τα γεγονότα αυτά καθώς και η γενικότερη παρουσία του ΙΔΝ όπως η ίδια ανιχνεύεται όχι μόνο σε εθνική αλλά και σε παγκόσμια κλίμακα, έχουν οδηγήσει σε μια κατάσταση συνεχούς παρακολούθησης και επιτήρησης της νόσου, με ιδιαίτερη έμφαση ως προς το κομμάτι καταπολέμησης των φορέων, δηλαδή των κουνουπιών, καθώς και τη λήψη προληπτικών μέτρων προστασίας που στοχεύουν στον εντοπισμό και στην καταπολέμηση μιας ενδεχόμενης εξελισσόμενης επιδημίας, σε πρώιμο στάδιο.
