description: Competing models arise naturally in many research fields, such as survival analysis and economics, when the same phenomenon of interest is explained by different researcher using different theories or according to different experiences. The model selection problem is therefore remarkably important because of its great importance to the subsequent inference; Inference under a misspecified or inappropriate model will be risky. Existing model selection tests such as Vuong's tests [26] and Shi's non-degenerate tests [21] suffer from the variance estimation and the departure of the normality of the likelihood ratios. To circumvent these dilemmas, we propose in this paper an empirical likelihood ratio (ELR) tests for model selection. Following Shi [21], a bias correction method is proposed for the ELR tests to enhance its performance. A simulation study and a real-data analysis are provided to illustrate the performance of the proposed ELR tests.

description: Thanks to the use of geolocated big data in computational social science research, the spatial and temporal heterogeneity of human activities are increasingly being revealed. Paired with smaller and more traditional data, this opens new ways of understanding how people act and move, and how these movements crystallise into the structural patterns observed by censuses. In this article we explore the convergence of mobile phone data with more classical socioeconomic data from census in French cities. We extract mobile phone indicators from six months worth of Call Detail Records (CDR) data, while census and administrative data are used to characterize the socioeconomic organisation of French cities. We address various definitions of cities and investigate how they impact the relation between mobile phone indicators, such as the number of calls or the entropy of visited cell towers, and measures of economic organisation based on census data, such as the level of deprivation, inequality and segregation. Our findings show that some mobile phone indicators relate significantly with different socioeconomic organisation of cities. However, we show that found relations are sensitive to the way cities are defined and delineated. In several cases, differing city definitions delineations can change the significance or even the signs of found correlations. In general, cities delineated in a restricted way (central cores only) exhibit traces of human activity which are less related to their socioeconomic organisation than cities delineated as metropolitan areas and dispersed urban regions.

description: We explicitly construct a supersymmetric $so(n)$ spin-Calogero model with an arbitrary even number $\cal N$ of supersymmetries. It features $\frac{1}{2}{\cal N}n(n{+}1)$ rather than ${\cal N}n$ fermionic coordinates and a very simple structure of the supercharges and the Hamiltonian. The latter, together with additional conserved currents, form an $osp({\cal N}|2)$ superalgebra. We provide a superspace description for the simplest case, namely ${\cal N}{=}2$ supersymmetry. The reduction to an $\cal N$-extended supersymmetric goldfish model is also discussed.

description: The eigen frequencies of radial pulsations of neutron stars are calculated in a strong magnetic field. At low densities we use the magnetic BPS equation of state(EOS) similar to that obtained by Lai and Shapiro while at high densities the EOS obtained from the relativistic nuclear mean field theory is taken and extended to include strong magnetic field. It is found that magnetised neutron stars support higher maximum mass where as the effect of magnetic field on radial stability for observed neutron star masses is minimal.

description: Tradução de leaflet do projeto AGFORWARD - A amoreira é utilizada como forragem em muitos países do mundo (por exemplo, na Índia e no Japão). As suas folhas têm um elevado teor de proteína (15-28%), um bom perfil de aminoácidos (> 46%), elevada digestibilidade (> 80%), alto conteúdo em minerais, com teor de cinzas até 25%, baixo teor em fibra (7,1-8,1%) e palatabilidade excelente. A elevada produção de biomassa, conjuntamente com o baixo teor em taninos, tornam estas plantas atraentes para a alimentação do gado. Além disso, as amoreiras são espécies excelentes para ultrapassar a falta de pastagem no verão, o que é um fator comum a vários países mediterrânicos.

description: A Lévy noise is an efficient description of out-of-equilibrium systems. The presence of Lévy flights results in a plenitude of noise-induced phenomena. Among others, Lévy flights can produce stationary states with more than one modal value in single-well potentials. Here, we explore stationary states in special double-well potentials demonstrating that a sufficiently high potential barrier separating potential wells can produce bimodal stationary states in each potential well. Furthermore, we explore how the decrease in the barrier height affects the multimodality of stationary states. Finally, we explore a role of the multimodality of stationary states on the noise induced escape over the static potential barrier.

description: Os métodos para beamforming adaptativo tem apresentado resultados positivos, melhorando a qualidade das imagens médicas por ultrassom, em comparação com a técnica não adaptativa Delay and Sum (DAS). O Generalized Sidelobe Canceler (GSC) pode melhorar consideravelmente a resolução lateral das imagens médicas de ultrassom, mas o contraste da imagem não é satisfatório. O EBMV (Eigenspace Based Minimum Variance) é um beamformer adaptável que pode suprimir uma grande parte do ruído e fornecer imagens com maior contraste e resolução em comparação com o DAS e o beamformer de mínima variância (MVB). Neste trabalho, foi aplicado o EBMV para imagens de ultrassom de ondas planas.
 Os dados de eco simulados foram obtidos no site Plane Wave Challenge em Medical Ultrasound Imaging (PICMUS). Os dados in vivo foram adquiridos usando um equipamento Verasonics Vantage 256 usando um transdutor de elementos L11-4v 128. Os resultados obtidos foram comparados com DAS
 e MVGSC e mostraram melhora da resolução lateral.

 Note, ratio-1 is very important, showing that Catalinia and the “ apacheanus ” group definitely have a reduced DPSc, showing significant MVD from the other two genera. The number of DPSc granules supports this result as well. Ratio-2 also supports the reduced DPSc but the MVD differences are negligible and therefore this ratio is not considered important.

Critical properties of projected SO(5) models at finite temperatures

description: We consider the projected SO(5) bosonic model introduced in order to connect the SO(5) theory of high-T$_c$ superconductivity with the physics of the Mott-insulating gap, and derive the corresponding effective functional describing low-energy degrees of freedom. At the antiferromagnetic-superconducting transition, SO(5) symmetry-breaking effects due to the gap are purely quantum mechanical and become irrelevant in the neighborhood of a possible finite-temperature multicritical point separating the normal from the antiferromagnetic and the superconducting phases. A difference in the magnon and hole-pair mobility always takes the system away from the SO(5)-symmetric fixed point towards a region of instability, and the phase transition between the normal and the two ordered phases becomes first order before merging into the antiferromagnetic-superconducting line. Quantum fluctuations at intermediate temperatures, while introducing symmetry-breaking terms in the case of equal mobilities, tend to cancel the symmetry-breaking effects in the case of different mobilities.

description: Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most other methods. Even in a well-studied cluster such as the Hyades, the masses of the red giant stars are not well known, and previous mass estimates are based on model calculations (isochrones). The four known red giants in the Hyades are assumed to be clump (core-helium-burning) stars based on their positions in colour-magnitude diagrams, however asteroseismology offers an opportunity to test this assumption. Using asteroseismic techniques combined with other methods, we aim to derive physical parameters and the evolutionary stage for the planet hosting star epsilon Tau, which is one of the four red giants located in the Hyades. We analysed time-series data from both ground and space to perform the asteroseismic analysis. By combining high signal-to-noise (S/N) radial-velocity data from the ground-based SONG network with continuous space-based data from the revised Kepler mission K2, we derive and characterize 27 individual oscillation modes for epsilon Tau, along with global oscillation parameters such as the large frequency separation and the ratio between the amplitude of the oscillations measured in radial velocity and intensity as a function of frequency. The latter has been measured previously for only two stars, the Sun and Procyon. Combining the seismic analysis with interferometric and spectroscopic measurements, we derive physical parameters for epsilon Tau, and discuss its evolutionary status.

description: We report Australia Telescope Compact Array (ATCA) radio-continuum and ROSAT PSPC X-ray observations of the region surrounding the peculiar galaxy pair ESO 295-IG022, lying at the centre of the poor cluster Abell S0102. We identify a radio galaxy coincident with the galaxy pair, with bipolar, bent radio jets appearing centred on the southern galaxy, and extending both to the south, for about 95 arcseconds (approximately 100 kpc at the distance of ESO 295-IG022), and to the north, for approximately 80 arcseconds, encompassing the northern galaxy. We discuss also the idea of an additional single jet structure from the northern galaxy contributing to the emission. We estimate lower limit jet velocities of at least 1000 km/s, and a relative proper velocity for the southern galaxy through the cluster of around 200 km/s. Diffuse (kT=2.2 keV) X-ray emission consistent with group or poor cluster emission is seen centred on the southern galaxy surrounding the galaxy pair and the associated radio jets. Structure within the radio jets and the X-ray emission is very suggestive of there being some channeling of the radio emission with the surrounding intragroup medium. Another bipolar jet radio galaxy, discovered close by, is likely to be a background object, the optical counterpart having a magnitude greater than m=22.

description: Dielectric spectroscopy covering more than 18 decades of frequency has been performed on propylene carbonate in its liquid and supercooled-liquid state. Using quasi-optic submillimeter and far-infrared spectroscopy the dielectric response was investigated up to frequencies well into the microscopic regime. We discuss the alpha-process whose characteristic timescale is observed over 14 decades of frequency and the excess wing showing up at frequencies some three decades above the peak frequency. Special attention is given to the high-frequency response of the dielectric loss in the crossover regime between alpha-peak and boson-peak. Similar to our previous results in other glass forming materials we find evidence for additional processes in the crossover regime. However, significant differences concerning the spectral form at high frequencies are found. We compare our results to the susceptibilities obtained from light scattering and to the predictions of various models of the glass transition.

description: In random systems consisting of grains with size distributions the transport properties are difficult to explore by network models. However, the concentration dependence of effective conductivity and its critical properties can be considered within coarsened lattice model proposed that takes into account information from experimentally known size histograms. For certain classes of size distributions the specific local arrangements of grains can induce either symmetrical or unsymmetrical critical behaviour at two threshold concentrations. Using histogram related parameters the non-monotonic behaviour of the conductor-insulator and conductor-superconductor threshold is demonstrated.

 Αρχικά γίνεται μια εισαγωγή για τις ακτίνες Χ σχετικά με την ανακάλυψή τους από τον Wilhelm Conrad Rӧntgen το 1895, τη μέθοδο δημιουργίας τους, τις χαρακτηριστικές τους ιδιότητες και τις εφαρμογές τους στην ιατρική, στη βιομηχανία, στην ασφάλεια των αεροδρομίων, στη μικροσκοπική ανάλυση με ακτίνες Χ και στην αστρονομία ακτίνων Χ.
Στη συνέχεια αναλύεται ο φθορισμός των ακτίνων Χ μέσω της μεθόδου του φθορισμού των ακτίνων Χ, τους ανιχνευτές ακτίνων Χ (Si-PIN X-Ray Detectors) που χρησιμοποιήθηκαν στις εργαστηριακές μετρήσεις και τους τομείς που βρίσκει εφαρμογή η μέθοδος XRF.
Μετέπειτα παρουσιάζονται αναλυτικότερα στοιχεία όπως ο κανόνας του Moseley, που αποτέλεσε τη μέθοδο προσδιορισμού και ανακάλυψης των χημικών στοιχείων του περιοδικού πίνακα, η ενέργεια ιονισμού, η φασματοσκοπία του ηλεκτρονίου Auger και τα είδη της ελαστικής και της ανελαστικής σκέδασης. Επίσης παρέχονται πληροφορίες για το Αμερίκιο (Am) και των ισοτόπων του καθώς το ισότοπο Αμερίκιο-241 (Am-241) χρησιμοποιήθηκε ως πηγή ενέργειας στη μέθοδο XRF, τον τρόπο ακτινοβόλησης, και την ποσοτικοποίηση με βάση την ένταση της ακτινοβολίας στη μέθοδο αυτή.
Στη συνέχεια αναλύεται η κατανομή των σπανίων γαιών σε μεταλλεύματα και ορυκτά, τις κατηγορίες των κοιτασμάτων που εντοπίζονται αλλά και την ύπαρξη τους στην υφαλοκρηπίδα και στον πυθμένα του ωκεανού. Επιπροσθέτως η αναφέρεται ο εμπλουτισμός των σπανίων γαιών, η σχέση τους με την ανακύκλωση, τη γεωργία αλλά και οι επιπτώσεις τους στο περιβάλλον και στην ανθρώπινη υγεία.
Ακολούθως αναπτύσσεται η γεωλογία της περιοχής μελέτης στις Σίσσες όπου λήφθηκε ένα μέρος των δειγμάτων που τέθηκαν σε ανάλυση. Επίσης αναλύονται τα αποτελέσματα προσδιορισμού των σπανίων γαιών σε πρότυπα δείγματα αναφοράς (Standard Reference Materials – SRM) για τη βαθμονόμηση του φορητού συστήματος XRF στα στοιχεία καίσιο (Cs), βάριο (Ba), λανθάνιο (La) και δημήτριο (Ce). Κατόπιν παρουσιάζονται οι αναλύσεις των γεωλογικών δειγμάτων στις Σίσσες και των PTNA IAEA 19 (SRM). Τέλος μελετάται η δυνατότητα αναλύσεων σε υγρά δείγματα  με βάση τη μεταβολή της απόδοσης σε σχέση με τη μάζα αλλά και με τον ατομικό αριθμό μέσω της ανάλυσης των υδατικών προτύπων σπανίων γαιών.

description: Millions of people worldwide use the Internet. One of the many uses derived from the Internet is the development of digital trade. Digital trade thus lends itself to distinctive issues. The WTO members recognized the benefits digital trade offers and have developed a work program to facilitate the digital trade. However, their efforts have stalled, slowing down the anticipated progress. The author will try to address how the WTO supports and deals with digital trade. This essay briefly discusses the historical advancement of the Internet; defines the concept of digital trade and its development in the international market; analyzes how existing WTO agreements have dealt with digital trade; and then addresses recent trade agreements particularly the USMCA. The USMCA was chosen because it involves the largest economy in the world and the US could use its provisions as template for future trade agreements

description: We propose a first principle computation of the equilibrium thermodynamics of simple fragile glasses starting from the two body interatomic potential. A replica formulation translates this problem into that of a gas of interacting molecules, each molecule being built of m atoms, and having a gyration radius (related to the cage size) which vanishes at zero temperature. We use a small cage expansion, valid at low temperatures, which allows to compute the cage size, the specific heat (which follows the Dulong and Petit law), and the configurational entropy.

description: NGC 1052-DF2, an ultra diffuse galaxy (UDG), has been the subject of intense debate. Its alleged absence of dark matter, and the brightness and number excess of its globular clusters (GCs) at an initially assumed distance of 20Mpc, suggested a new formation channel for UDGs. We present the first systematic spectroscopic analysis of both the stellar body and the GCs (six of which were previously known, and one newly confirmed member) of this galaxy using MUSE@VLT. Even though NGC 1052-DF2 does not show any spatially extended emission lines we report the discovery of three planetary nebulae (PNe). We conduct full spectral fitting on the UDG and the stacked spectra of all GCs. The UDG's stellar population is old, 8.9$\pm$1.5 Gyr, metal-poor, with [M/H] = $-$1.07$\pm$0.12 with little or no $α$-enrichment. The stacked spectrum of all GCs indicates a similar age of 8.9$\pm$1.8 Gyr, but lower metallicity, with [M/H] = $-$1.63$\pm$0.09, and similarly low $α$-enrichment. There is no evidence for a variation of age and metallicity in the GC population with the available spectra. The significantly more metal-rich stellar body with respect to its associated GCs, the age of the population, its metallicity and alpha enrichment, are all in line with other dwarf galaxies. NGC 1052-DF2 thus falls on the same empirical mass-metallicity relation as other dwarfs, for the full distance range assumed in the literature. We find that both debated distance estimates (13 and 20 Mpc) are similarly likely, given the three discovered PNe.

description: Spin-orbit torques (SOT) in thin film heterostructures originate from strong spin-orbit interactions (SOI) that, in the bulk, generate a spin current as the result of extrinsic spin-dependent, skew or/and side-jump, scattering, or in the intrinsic case due to Berry curvature in the conduction band. While most SOT studies have focused on materials with heavy metal components, the oxide perovskite SrRuO3 has been predicted to have a pronounced Berry curvature. Through quantification of its spin current by the SOT exerted on an adjacent Co ferromagnetic layer, we determine that SrRuO3 has a strongly temperature (T) dependent spin Hall conductivity which becomes particularly high at low T, e.g. σ_{SH} \geqslant (\hbar/2e)3x10^{5} Ω^{-1}m^{-1} at 60 K. Below the SrRuO3 ferromagnetic transition, non-standard SOT components develop associated with the magnetic characteristics of the oxide, but these do not dominate as with spin currents from a conventional ferromagnet. Our results establish a new approach for the study of SOI in epitaxial conducting oxide heterostructures and confirm SrRuO3 as a promising candidate material for achieving new and enhanced spintronics functionalities.

description: The incoherent regime of Multiple Andreev Reflections (MAR) is studied in long diffusive SNS junctions at applied voltages larger than the Thouless energy. Incoherent MAR is treated as a transport problem in energy space by means of a circuit theory for an equivalent electrical network. The current through NS interfaces is explained in terms of diffusion flows of electrons and holes through tunnel and Andreev resistors. These resistors in diffusive junctions play roles analogous to the normal and Andreev reflection coefficients in OTBK theory for ballistic junctions. The theory is applied to the subharmonic gap structure (SGS); simple analytical results are obtained for the distribution function and current spectral density for the limiting cases of resistive and transparent NS interfaces. In the general case, the exact solution is found in terms of chain-fractions, and the current is calculated numerically. SGS shows qualitatively different behavior for even and odd subharmonic numbers, and the maximum slopes of the differential resistance correspond to the gap subharmonics. The influence of inelastic scattering on the subgap anomalies of the differential resistance is analyzed.

description: We have calculated a grid of massive star wind models and mass-loss rates for a wide range of metal abundances between 1/100 and 10 Z/Zsun. The calculation of this grid completes the Vink et al. (2000) mass-loss recipe with an additional parameter Z. We have found that the exponent of the power law dependence of mass loss vs. metallicity is constant in the range between 1/30 and 3 Z/Zsun. The mass-loss rate scales as Mdot \propto Z^0.85 Vinf^p with p = -1.23 for stars with Teff \ga 25000 K, and p = -1.60 for the B supergiants with Teff \la 25000 K. Taking also into account the metallicity dependence of Vinf, using the power law dependence Vinf \propto Z^0.13 from Leitherer et al. (1992), the overall result of mass loss as a function of metallicity can be represented by Mdot \propto Z^0.69 for stars with Teff \ga 25000 K, and Mdot \propto Z^0.64 for B supergiants with Teff \la 25000 K. Our mass-loss predictions are successful in explaining the observed mass-loss rates for Galactic and Small Magellanic Cloud O-type stars, as well as in predicting the observed Galactic bi-stability jump. Hence, we believe that our predictions are reliable and suggest that our mass-loss recipe be used in future evolutionary calculations of massive stars at different metal abundance. A computer routine to calculate mass loss is publicly available.

description: In a recent Letter (Phys. Rev. Lett. 81, 4200 (1998)) Park and Jain presented results of gap calculations for polarized states at ν=1/3, 2/5, 3/7 and 4/9. They computed the effects on the gaps due the finite width of the interfacial wave function (wf). In this Comment, it is shown that the reduction of the gaps due to the finite width of the wf is overestimated by about a factor of two. The agreement between theoretical and experimental gap values cannot be taken seriously, but results from an incorrect determination of the width parameter.

description: Purpose: Teacher ratings were used to compare children with developmental language disorders (DLD) and their typically developing peers on 2 subtypes of social withdrawal (shyness and unsociability). Measurement invariance analysis was utilized to determine if teachers rated the 2 groups using the same underlying construct for each of the rating scale items that have been designed to assess withdrawn behavior.Method: The Teacher Behavior Rating Scale (TBRS; C. H. Hart & Robinson, 1996) was administered to the teachers of 173 children with DLD and 182 typically developing children (age range: 5;0–12;11 years;months) to compare 2 subtypes of withdrawal, shyness and unsociability. Measurement invariance analysis was used to establish an appropriate basis for comparing the latent group means and other structural parameters, and partial invariance models were used to compare the groups.Results: For the TBRS, shyness and unsociability were measured by 4 and 5 items, respectively. The measurement invariance analysis indicated that classroom teachers approached 1 item on each of these scales using a different underlying construct when rating the 2 groups of children. Taking this into account, the groups were compared. Teachers rated children with DLD as significantly more withdrawn on both shyness and unsociability in comparison with typically developing children. Age and gender were not significant factors.Conclusions: When conducting assessments, it should not be assumed that teachers or other raters approach even commonly used rating scale items using the same underlying perception for typically developing children and children with disorders. However, the analysis of invariant items on the TBRS reconfirmed that children with DLD are at risk for social withdrawal as operationalized by assessments of both shyness and unsociability.

description: Surface flows are excited by steadily adding spherical glass beads to the top of a heap. To simultaneously characterize the fast single-grain dynamics and the much slower collective intermittency of the flow, we extend photon-correlation spectroscopy via fourth-order temporal correlations in the scattered light intensity. We find that microscopic grain dynamics during an avalanche are similar to those in the continuous flow just above the transition. We also find that there is a minimum jamming time, even arbitrarily close to the transition.

A Useful Approximation for Computing the Continuum Polarization of Be Stars

Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper describes a practical model for the polarization of Be stars which can be used to estimate roughly the physical parameters for optically thin circumstellar envelopes from broadband UBVRI photopolarimetry data. Analysis of long-term variability in terms of these parameters is a promising approach toward understanding the Be phenomenon. An interesting result from fitting the model to observations of eight Be stars is that all of them may have geometrically thin disks, with opening half-angles on the order of ten degrees or less. This contributes to the growing evidence that most Be disks are geometrically thin.

description: The application of social media within programs has grown exponentially over the past decade and have become a popular way for programs to engage and reach their stakeholders and inform engagement efforts. Consequently, organizations are utilizing data analytics from social media platforms as a way to measure impact. These data can help programs understand how program objectives, progress, and outcomes are disseminated and used (i.e., through discussions, viewing of content, following program social media pages). The Office of Educational Innovation and Evaluation (OEIE) conducted a presentation at the 2018 AEA (American Evaluation Association) national conference on a novel technique that utilizes social media analytics to demonstrate program impact. Conference participants learned from OEIE's first-hand experience using a framework to make social media metrics more powerful, the power in aligning the framework to program objectives, the truth that is spoken in analyzing and visualizing social media metrics, and next steps for future use in evaluation. In the presentation, OEIE shared their experience applying this analytic technique to the social media efforts of a multi-institutional program.

description: Was bedeutet Erfolg, was Messbarkeit im Zusammenhang mit Kunst? Welche unterschiedlichen Vorstellungen von Ordnung gibt es im Kunstfeld und wie fließen diese in Ordnungsangebote wie Ranglisten, aber auch Ausstellungen ein? In „Die Vermessung der Kunstwelt. Quantifizierende Beobachtungen und plurale Ordnungen der Kunst“ widmet sich der Soziologe Paul Buckermann einem innerhalb der Sphäre der Kunst fast tabuisierten Thema, das diese zugleich einflussreich bestimmt: quantifizierende und standardisierende Verfahren zur Kunst. In einer komparativ angelegten kunstsoziologischen Studie des Kunstrankings „Kunstkompass“ und der Ordnungspraxis öffentlicher Kunstmuseen untersucht Buckermann zwei sehr unterschiedliche Ordnungsweisen innerhalb des Kunstfelds im Hinblick auf ihre Verfahren, Adressatinnen und Adressaten und Bezugsprobleme. „Die Vermessung der Kunstwelt“ schließt nicht nur an kunstwissenschaftliche Diskurse um künstlerische Autonomie, die Soziologie der Bewertung und die Museumsforschung an, sondern auch an Diskurse der Kunstkritik, die als Ordnungsinstanz in eben diesen Diskursen agiert.
