The Unified Model of Active Galactic Nuclei: I. Non-hidden Broad Line Region Seyfert 2 and Narrow Line Seyfert 1 Galaxies

description: The unified model of Seyfert galaxies suggests that there are hidden broad-line regions (HBLRs) in Seyfert 2 galaxies (S2s). However, there is increasing evidence for the appearance of a subclass of S2s lacking of HBLR (non-HBLR S2s). An interesting issue arises as to relations of non-HBLR S2s with other types of Seyfert galaxies and whether or not they can be included in the unified model. We assemble two sub-samples consisting of 42 non-HBLR S2s and 44 narrow-line Seyfert 1s (NLS1s) with redshift $z\le 0.05$ from published literatures to explore this issue. We compare black hole masses in the galactic centers, accretion rates, infrared color ratio ($f_{60 μ\rm m}/f_{25 μ\rm m}$) as a potential indicator of the dusty torus orientation, \oiii $λ5007$, radio and far infrared luminosities. We find that non-HBLR S2s and NLS1s have: 1) similar distributions of the black hole masses ($10^6-3\times 10^7\sunm$) and the Eddington ratios ($L_{\rm Bol}/L_{\rm Edd}\sim 1$); 2) significantly different distributions of $f_{60 μ\rm m}/f_{25 μ\rm m}$ ratios; 3) similar distributions of bulge magnitudes and luminosities of [O {\sc iii}], radio, far infrared emission. The similarities and differences can be understood naturally if they are intrinsically same but non-HBLR S2s are viewed at larger angles of observer's sight than NLS1s. We thus suggest that non-HBLR S2s only have "narrower" broad line regions and they are the counterparts of NLS1s viewed at high inclination angles. The absence of the polarized emission line in non-HBLR S2s is caused by the less massive black holes and high accretion rate similar to NLS1s. The implications of the unification scheme of non-HBLR S2s and NLS1s are discussed.

Crazy Krizia

description: Il saggio vuole restituire una analisi su alcune collezioni degli anni Ottanta di Krizia (Maria Mandelli, 1925-2015). Lo studio parte dall’analisi dell’archivio CSAC, da cui emerge un fondo , ancora parzialmente inedito, dedicato appunto a Krizia, una stilista che - come afferma Umberto Eco - ha stretto rapporti con la letteratura, il teatro e la pittura, in quanto per Eco: “come le arti anche la moda è specchio del proprio tempo, e crea social meaning”. Krizia da sempre impegnata nella sperimentazione di nuovi materiali, tagli e di fonti di ispirazione, si colloca negli anni Ottanta come una figura che si muove in modo ibrido tra le varie culture assorbendone modelli, poetiche e stati mentali. Una fashion designer che “come canale di osservazione” sugli anni Ottanta è in grado di restituire quel clima postmoderno sintetizzato, come afferma Gianni Vattimo, nei concetti di pluralismo, indebolimento del senso di realtà e estetizzazione generale della vita quotidiana. Il fondo Krizia comprende circa 25509 opere (prima donazione) cui si aggiungono 14597 opere (seconda acquisizione), per un arco cronologico da 1967 al 2000. Sono conservati figurini, disegni, schizzi, tecnica mista su carta e cartoncino e fotocopie e campioni di tessuto applicati su molti disegni.

Subjects: arte contemporanea; ricamo; tessitura; tessuto; anni ottanta

description: Oltre al “ritorno alla pittura”, nell’arte degli anni Ottanta del Novecento si assiste anche allo sdoganamento di pratiche prima di allora ritenute essenzialmente artigianali o marginali come il ricamo e la tessitura. In un periodo caratterizzato dalla grande libertà e dalla possibilità di mescolare l’alto e il basso, il filo e il tessuto diventano dei potenti alleati degli artisti ma soprattutto delle artiste. Negli anni Ottanta il ricamo e la tessitura si trasformano in strumenti di comunicazione personale e politica dalle diverse sfaccettature. Dai coloratissimi femmage di Miriam Shapiro alle opere tessute a mano di Magdalena Abakanowicz, dai Libri di Maria Lai ai ricami di Alighiero Boetti, nelle opere realizzate da questi artisti con il cucito e la tessitura si affacciano tutta una serie di temi che si riveleranno importanti per gli artisti degli anni Novanta, se non altro per il comune sintonizzarsi su narrazioni che da private diventano pubbliche e politiche. L’obiettivo è di ripercorrere alcune delle tematiche fondamentali affrontate dagli artisti negli anni Ottanta prendendo come osservatorio privilegiato le opere create con tessuti, fili e stoffe: una storia che, per certi versi, ha ancora molto da raccontare.

Equidistant quenches in few-level quantum systems

description: A recent work [Phys. Rev. Lett. 125, 110602] showed that among a pair of \textit{thermodynamically} equidistant quenches from a colder and a hotter initial state at a fixed ambient temperature, the relaxation from the colder initial state (\textit{uphill} relaxation) is always faster, for dynamics close to stable minima. Here we show that this is not generically the case for open quantum systems with two or three energy levels. We find that both faster uphill and faster downhill relaxation and symmetric thermal relaxation can be observed in equidistant quenches, depending on the transition rates and the choice of the distance measure used. Furthermore, we obtain a phase diagram in the parameter space for the three-level system corresponding to different thermalization behaviours.

description: We present N-band spectro-interferometric observations of the red supergiant WOH G64 in the Large Magellanic Cloud (LMC) using MIDI at the Very Large Telescope Interferometer (VLTI). The location of WOH G64 on the H-R diagram based on the previously estimated luminosities is in serious disagreement with the current stellar evolution theory. The dust envelope around WOH G64 has been spatially resolved with a baseline of ~60 m--the first MIDI observations to resolve an individual stellar source in an extragalactic system. The observed N-band visibilities show a slight decrease from 8 to 10 micron and a gradual increase longward of 10 micron, reflecting the 10 micron silicate feature in self-absorption. The visibilities measured at four position angles differing by ~60 degrees but at approximately the same baseline length (~60 m) do not show a noticeable difference, suggesting that the object appears nearly centrosymmetric. The observed N-band visibilities and spectral energy distribution can be reproduced by an optically and geometrically thick silicate torus model viewed close to pole-on. The luminosity of the central star is derived to be 2.8 x 10^5 Lsun, which is by a factor of 2 lower than the previous estimates based on spherical models. The lower luminosity newly derived from our MIDI observations and two-dimensional modeling brings the location of WOH G64 on the H-R diagram in much better agreement with theoretical evolutionary tracks for a 25 Msun star. We also identify the H2O absorption features at 2.7 and 6 micron in the spectra obtained with the Infrared Space Observatory and the Spitzer Space Telescope. The 2.7 micron feature originates in the photosphere and/or the extended molecular layers, while the 6 micron feature is likely to be of circumstellar origin.

description: We examine how the location of star formation within disc galaxies depends on environment at intermediate redshift. This is achieved by comparing emission-line (r_em) and restframe B-band (r_B) scalelengths for matched samples of 50 field and 19 cluster star-forming, disc galaxies, with 0.25 < z < 1.0 and M_B < -19.5 mag. We find that at a given r_B the majority of our cluster galaxies have r_em smaller than those in the field, by 25 percent on average. These results are compared with studies of local galaxies, which find a very similar behaviour. From the relations of r_em and r_B versus B-band absolute magnitude (M_B) we infer that the difference between the intermediate-z cluster and field samples is mostly attributable to variation in r_em at a given M_B, while the r_B versus M_B relation is similar for the two samples.

Social anxiety and depression: interpersonal behavior and reactions

Publisher: name: University of British Columbia
Year: 2009

description: The present study examined the self-disclosure of socially anxious and depressed-mood women students within the context of a face-to-face dyadic interaction. It also examined the influence of the interaction on their levels of affect, physiological arousal, and acceptance of their partners. The impact of the interaction on their partners' affect and acceptance was also explored. The results showed that anxious and depressed-mood subjects exhibited different, and specific patterns of inappropriate disclosure. The socially anxious subjects exhibited reduced amounts of nonreciprocal disclosure which was best characterized as moderate in nature. The depressed-mood subjects displayed increased amounts of overly intimate, negatively valanced disclosure. The results also indicated that before the interaction the subjects varied on the measures of affect and arousal as a function of their status on the subject selection variables and that the interaction had different effects on the different types of subjects. The socially anxious subjects were characterized by lower preinteraction levels of positive affect and higher levels of negative affect. The interaction had a negative effect on them, it maintained their low levels of positive affect, high levels of negative affect, and increased their levels of physiological arousal. The depressed mood subjects were characterized by lower preinteraction levels of positive affect, and higher levels of negative affect and physiological arousal. The interaction was positive for them, however, as they experienced increases in their positive affect and decreases in their negative affect. The socially anxious subjects were rejected by their partners but induced neither positive nor negative affect in them. The depressed-mood subjects were not rejected by their partners but created an ambivalent emotional reaction in them. The results are discussed within an interpersonal framework and suggest that a reinterpretation of Coyne's (1976) model provides a good conceptual framework to explain these, and other recent results. The possible developmental framework for maladaptive interpersonal behaviours is explored within a modification of Arkin's (1981) social motivational model. The results of this study are also discussed in the context of a tripartite model of anxiety and depression and provide partial support for that model.

description: In this article, we describe a new method of extracting information from signals, called functional dissipation, that proves to be very effective for enhancing classification of high resolution, texture-rich data. Our algorithm bypasses to some extent the need to have very specialized feature extraction techniques, and can potentially be used as an intermediate, feature enhancement step in any classification scheme. Functional dissipation is based on signal transforms, but uses the transforms recursively to uncover new features. We generate a variety of masking functions and `extract' features with several generalized matching pursuit iterations. In each iteration, the recursive process modifies several coefficients of the transformed signal with the largest absolute values according to the specific masking function; in this way the greedy pursuit is turned into a slow, controlled, dissipation of the structure of the signal that, for some masking functions, enhances separation among classes. Our case study in this paper is the classification of crystallization patterns of amino acids solutions affected by the addition of small quantities of proteins.

description: In a many-spin approach that takes account of the internal structure, microscopic interactions and single-site anisotropies, we investigate the effect of spin non-collinearities induced by the boundary and surface anisotropy on the behaviour of individual magnetic nanoparticles. Through analytical and numerical calculations, we show that there are mainly two regimes separated by some critical value of the surface anisotropy constant $K_s$ which controls the intensity of spin non-collinearities: i) the so called Stoner-Wohlfarth or Néel-Brown regime of a macrospin undergoing a coherent switching, ii) the many-spin regime where the strong spin non-collinearities invalidate the coherent mechanism, and where the particle's magnetic state and switching mechanisms can no longer be modeled by a macrospin. For small-to-intermediate values of $K_s$, and within two models of surface anisotropy (transverse and Néel), the behaviour of the nanoparticle can be modeled by that of a macrospin with an effective potential energy containing a uniaxial and cubic anisotropy terms. This effective spin model provides a crossover between the two regimes.

description: We study two effective models developed for description of superconductors with short-coherence length: (i) the extended Hubbard model with on-site attraction and intersite repulsion, (ii) the model of hard-core charged bosons on a lattice. The analysis is concentrated on the problem of phase separations and competition between superconductivity (SS) and charge-density-wave (CDW) orderings. The phase diagrams of the systems are shown to consist of at least seven different states, including 3 types of phase separated (PS) states: CDW-SS (PS1), CDW-normal (PS2) and the state of electron droplets (PS3). By taking into account the PS states and the effects of longer-range density-density interactions (beyond nearest neighbours) our work substantially generalizes and modifies the conclusions of previous works concerning the models considered.

description: (Abridged) We present results of several X-ray observations of the X-ray binary 4U 1954+31 performed with the satellites BeppoSAX, EXOSAT, ROSAT, RXTE, and Swift. We also studied the RXTE ASM data over a period of more than 10 years. Light curves of all observations show an erratic behaviour with sudden increases in the source emission on timescales variable from hundreds to thousands of seconds. There are no indications of changes in the source spectral hardness, with the possible exception of the RXTE pointed observation. Timing analysis does not reveal the presence of coherent pulsations or periodicities either in the pointed observations in the range from 2 ms to 2000 s or in the long-term RXTE ASM light curve on timescales from days to years. The 0.2-150 keV spectrum, obtained with BeppoSAX, is the widest for this source available to date in terms of spectral coverage and is well described by a model consisting of a lower-energy thermal component (hot diffuse gas) plus a higher-energy (Comptonization) emission, with the latter modified by a partially-covering cold absorber plus a warm (ionized) absorber. A blackbody modelization of our BeppoSAX low-energy data is ruled out. The presence of a complex absorber local to the source is also supported by the 0.1-2 keV ROSAT spectrum. RXTE, EXOSAT and Swift X-ray spectroscopy is consistent with the above results, but indicates variations in the density and the ionization of the local absorber. A 6.5 keV emission line is possibly detected in the BeppoSAX and RXTE spectra. All this information suggests that the scenario that better describes 4U 1954+31 consists of a binary system in which a neutron star orbits in a highly inhomogeneus medium from a stellar wind coming from its optical companion, an M-type giant star.

description: We study the formation of the first generation of stars in the standard cold dark matter model, using a very high-resolution hydordynamic simulations. Our simulation achieves a dynamic range of 10^{10} in length scale. With accurate treatment of atomic and molecular physics, it allows us to study the chemo-thermal evolution of primordial gas clouds to densities up to n = 10^{16}/cc without assuming any a priori equation of state; a six orders of magnitudes improvement over previous three-dimensional calculations. All the relevant atomic and molecular cooling and heating processes, including cooling by collision-induced continuum emission, are implemented. For calculating optically thick H2 cooling at high densities, we use the Sobolev method. To examine possible gas fragmentation owing to thermal instability, we compute explicitly the growth rate of isobaric perturbations. We show that the cloud core does not fragment in either the low-density or high-density regimes. We also show that the core remains stable against gravitational deformation and fragmentation. We obtain an accurate gas mass accretion rate within a 10 Msun innermost region around the protostar. The protostar is accreting the surrounding hot gas at a rate of 0.001-0.01 Msun/yr. From these findings we conclude that primordial stars formed in early minihalos are massive. We carry out proto-stellar evolution calculations using the obtained accretion rate. The resulting mass of the first star is M_ZAMS = 60-100 Msun, with the exact mass dependent on the actual accretion rate.

description: The effects of population size, mating strategy, and selection on selection response, genetic drift, and variability of response were studied in small Japanese quail populations. The effects of population size on genetic gain, variability of response and inbreeding were examined for a 3 generation phenotypic selection experiment. Effective population sizes of 12 (Large) and 6 (Small) per replicate were evaluated at the same selection intensity. The selection criterion was Week 2 body weight in Japanese quail. Estimates of genetic gain at Generation 3 were 10.67 and 8.89 grams, respectively for the large and small populations. A selection experiment involving 3 mating strategies was conducted in order to evaluate the efficiency of selection and effectiveness of reducing genetic drift and/or inbreeding in small populations. The mating strategies used were random (RM), minimum coancestry (MN), and maximum coancestry (MX) mating. Genetic gain at Generation 3 was 7.03, 7.36 and 6.62 grams and inbreeding levels were 6%, 4% and 12% in the RM, MN and MX lines, respectively. After 3 generations of selection, inbreeding effective population size had declined by 62% in the MX lines. In the MN lines, inbreeding effective population size increased by 16%. The effects of inbreeding on reproductive performance were studied in the large and small populations (Experiment I) and the RM, MN and MX lines (Experiment II). Ten percent increase in the embryo’s inbreeding caused about 10% reduction in fertility in both experiments. Ten percent increase in the embryo’s inbreeding caused 10% reduction in hatchability in Experiment I and RM lines in Experiment II, and about 13% reduction in hatchability in MX lines. The goal of short-term selection has been to maximize genetic gain. Results from the present study suggest that the goal of a breeding program for small populations should shift from maximization of response to optimization of genetic gain and effective population size. Among the factors to be optimized are rate of selection, variability of response, inbreeding depression in the selection trait and fitness. Restriction of family size coupled with the use of either circular pair or maximum avoidance mating is preferred over within-family selection under random mating or mass selection with maximum avoidance in terms of reducing inbreeding in small populations undergoing artificial selection.

Εξετάσαμε την ορολογία που χρησιμοποιείται για τις εκπαιδευτικές εφαρμογές των Τ.Π.Ε. στην εκπαίδευση. Στη συνέχεια, παρουσιάσαμε αναλυτικά όλες οι εφαρμογές των Τ.Π.Ε. που αποτελούν το υλικό της κατάρτισης των επιμορφωμένων εκπαιδευτικών και μια σύντομη ιστορική ανασκόπηση στο θεσμό της Επιμόρφωσης Α΄ και Β΄ Επιπέδου. Ακόμη αναφερθήκαμε αναλυτικά στις θεωρίες μάθησης με χρήση των Τ.Π.Ε. καθώς και στις σύγχρονες προσεγγίσεις στη διδακτική. Ένα άλλο θέμα που θίξαμε ήταν η εισαγωγή και ένταξη των Τεχνολογιών της Πληροφορίας και της Επικοινωνίας (Τ.Π.Ε.) στο ελληνικό εκπαιδευτικό σύστημα. Ασχοληθήκαμε επιπλέον με τις έρευνες τόσο στον ελληνικό χώρο, όσο και στον διεθνή για την ένταξη και εφαρμογή των Τ.Π.Ε. στη σύγχρονη εκπαιδευτική διαδικασία και διαπιστώσαμε την απουσία τους ιδιαίτερα στον ελληνικό χώρο.
description: The purpose of this study was to examine whether teachers of Primary Education of the prefecture of Serres, who participated in the training program level B, by completing their training on the pedagogical use of technology, are able to convert theories of learning through technology in the teaching practice. We also scrutinized the terminology used for the educational applications of ICT (Information and Communication Technology) in education. Then, we presented in detail all ICT applications, which constitute the actual material of the instruction of the teachers who were educated, and a brief historical overview of the institution of Training A and B Level. Further, we elaborated on theories of learning using ICT and the modern approaches to teaching. In addition to this, we discussed the introduction and integration of Information and Communication Technology ( ICT ) in the Greek educational system. Finally, we dealt with research, both in the Greek and international area, on the integration and application of ICT in the contemporary educational process and realized their absence especially in the Greek area.

description: A jet model for Galactic black-hole X-ray binaries will be presented that appears to explain several observational characteristics. In particular, it explains the energy spectrum from radio to hard X-rays, the time-lags as a function of Fourier frequency, the increase of the variability amplitude (QPO and high frequency) with increasing photon energy, and the narrowing of the autocorrelation function with increasing photon energy. On the other hand, there are additional observational constraints that no model has tried to explain yet. It is important that we all try to address these constraints if we are to make any progress in understanding black-hole X-ray sources

description: Combining results of Wahl, Galatius--Madsen--Tillmann--Weiss and Korkmaz one can identify the homotopy-type of the classifying space of the stable non-orientable mapping class group $N_\infty$ (after plus-construction). At odd primes p, the F_p-homology coincides with that of $Q_0(HP^\infty_+)$, but at the prime 2 the result is less clear. We identify the F_2-homology as a Hopf algebra in terms of the homology of well-known spaces. As an application we tabulate the integral stable homology of $N_\infty$ in degrees up to six. As in the oriented case, not all of these cohomology classes have a geometric interpretation. We determine a polynomial subalgebra of $H^*(N_\infty ; F_2)$ consisting of geometrically-defined characteristic classes.

description: Glioblastoma multiforme (GBM), like the devastating type of astrocytic tumors, is one of the most challenging cancers to treat owing to its aggressive nature. Auraptene, as a prenyloxy coumarin from citrus species, represents antioxidant and antitumor activities; however, the underlying antitumor mechanisms of auraptene against GBM remain unclear. The present study aimed to evaluate the cytotoxic and apoptogenic effects of auraptene, as a promising natural product, and the possible signaling pathways affected in human malignant GBM (U87) cells. Reactive oxygen species (ROS) production significantly decreased in the first 2, and 6 hours after treatment with auraptene however, ROS levels increased in other incubation times (8 and 24 hours), dramatically. N-acetyl-cysteine (NAC) markedly attenuated auraptene–induced ROS production, and consequently reversed auraptene–induced cytotoxicity in 8 and 24 hours after treatment, as well. Induction of apoptosis occurred in the first 24- and 48-hours concentration-dependently. The qRT-PCR showed an up-regulation in p21, CXCL3, and a down-regulation in Cyclin D1 genes expression. Western blot analysis confirmed the up-regulation of the Bax/Bcl-2 ratio protein levels concentration-dependently. Hence, this study collectively revealed that the increase in ROS level is at least one of the mechanisms associated with auraptene-induced GBM cell toxicity as well as the induction of apoptosis through Bax/Bcl-2 modulation and genes expression involved that contribute to the cytotoxicity of auraptene in U87 cells. So, auraptene might be utilized as a potential novel anti-GBM agent after further studies.

Non-Abelian vortices in Chern-Simons theories and their induced effective theory

description: Non-Abelian vortices for a supersymmetric {\cal N}=2 Chern-Simons-Higgs theory are explicitly constructed. We introduce N Higgs fields in the fundamental representation of the U(N) gauge group in order to have a color-flavor SU(N) group remaining unbroken in the asymmetric phase. Bogomol'nyi-like first order equations are found and rotationally symmetric solutions are proposed. These solutions are shown to be truly non-Abelian by parameterizing them in terms of orientational collective coordinates. The low energy effective action for the orientational moduli results to be the one-dimensional supersymmetric {\cal N}=2 CP^{N-1} model. We analyze the quantum mechanics of this effective theory in the N=2 case.
