description: Combining XMM-Newton and Chandra data, we have performed a detailed study of Abell 3558. Our analysis shows that its dynamical history is more complicated than previously thought. We have found some traits typical of cool core clusters (surface brightness peaked at the center, peaked metal abundance profile) and others that are more common in merging clusters, like deviations from spherical symmetry in the thermodynamic quantities of the ICM. This last result has been achieved with a new technique for deriving temperature maps from images. We have also detected a cold front and, with the combined use of XMM-Newton and Chandra, we have characterized its properties, such as the speed and the metal abundance profile across the edge. This cold front is probably due to the sloshing of the core, induced by the perturbation of the gravitational potential associated with a past merger. The hydrodynamic processes related to this perturbation have presumably produced a tail of lower entropy, higher pressure and metal rich ICM, which extends behind the cold front for about 500 kpc. The unique characteristics of A3558 are probably due to the very peculiar environment in which it is located: the core of the Shapley supercluster.

description: Correlations of non-photonic electrons with charged hadrons are studied using the PYTHIA Monte Carlo event generator in p+p collisions at $\sqrt{s_{NN}} = 200$ GeV. We propose experimental methods to estimate the relative contributions to non-photonic electrons from charm and bottom decays. We present the measurement of azimuthal correlations between non-photonic electrons and charged hadrons in p+p collisions at $\sqrt{s_{NN}} = 200$ GeV from STAR. The results are compared to PYTHIA simulations to estimate the relative contributions of $D$ and $B$ meson semi-leptonic decays to non-photonic electrons. Our preliminary result indicates that at $p_{T} \sim 4.0 - 6.0$ GeV/c the measured $B$ contribution to non-photonic electrons is comparable to $D$ contribution, and is consistent with the FONLL calculation.

description: We present narrow-band images of the Red Rectangle (RR) nebula which reveal the distinct morphologies of this intriguing nebula in different optical emission bands. The morphology of the RR nebula in blue luminescence (BL) and extended red emission (ERE) are almost mutually exclusive. We also present the optical detection of the circum-binary disk of the RR in the light of the BL. The total intensities from the two optical band emissions (BL and ERE) when summed over the nebula are of comparable magnitude. Their spatial distributions with respect to the embedded illumination sources lead us to suggest that they may be attributed to different ionization stages of the same family of carriers.

description: Spinor-vector dualities have been established in various exact string realisations like orbifold and free fermionic constructions. This paper aims to investigate possibility of having spinor-vector dualities on smooth geometries in the context of the heterotic string. As a concrete working example the resolution of the T4/Z2 orbifold is considered with an additional circle supporting a Wilson line, for which it is known that the underlying orbifold theory exhibits such a duality by switching on/off a generalised discrete torsion phase between the orbifold twist and the Wilson line. Depending on this phase complementary parts of the twisted sector orbifold states are projected out, so that different blowup modes are available to generate the resolutions. As a consequence, not only the spectra of the dual pairs are different, but also the gauge groups are not identical making this duality less apparent on the blowup and thus presumably on smooth geometries in general.

Pathways into the dark : three windows on Judith Thompson’s Lion In The Streets
Creators: name: Lindsay, Kathleen M.
Publisher: name: University of British Columbia
Year: 2008

description: In the plays of Judith Thompson there is a common conflict, that of the animal caged, a metaphor for the battle that ensues between the conscious and the unconscious, between social propriety and animal desire. In Lion In The Streets Thompson explores the relationship of the individual to society. How the individual personality, through socialization in our modern world, becomes tormented and twisted. This thesis offers three separate and distinct frames through which we may decipher the labyrinth of image and thought in Lion, and as I approached the play three main questions drove my investigation. My first interest is in decoding the true conflict of Lion. Although a great deal of violence is perpetrated between characters, this is simply a masking of the true violence which is internalized. Through the application of a Freudian framework the true conflict is identified and we come to a realization of the intense and intimate realtionship existing between the conscious and the unconscious. The second chapter deals with the spine of the play, Isobel’s journey. When reading the script I found Isobel to be the driving force of the plot, yet, in the performance of Lion at Touchstone Theatre in Vancouver, I was bemused by the way Isobel faded from focus as the numerous vignettes drove the plotline. In an attempt to clarify the throughline of the journey, I have incorporated a Jungian model that exposes Isobel’s journey as the internalized journey to self-realization. In the third chapter, the theatrical world of Judith Thompson is discussed. A world of absolute artistic licence, disinterested in the conventions of realism, and based in the free association of image and action. Here we are thrown into a realm of imagination where there is no distinction between the real and the imagined, between life and death, between past and future. And Lion thrives on the internal dialogue of its characters where unconscious thought and feeling is exposed as the characters are stripped of their public skins. In Lion, Thompson has created a dream landscape that leaves its characters hanging perilously on the edge of nightmare.

description: Recently, Rendle has warned that the use of sampling-based top-$k$ metrics might not suffice. This throws a number of recent studies on deep learning-based recommendation algorithms, and classic non-deep-learning algorithms using such a metric, into jeopardy. In this work, we thoroughly investigate the relationship between the sampling and global top-$K$ Hit-Ratio (HR, or Recall), originally proposed by Koren[2] and extensively used by others. By formulating the problem of aligning sampling top-$k$ ($SHR@k$) and global top-$K$ ($HR@K$) Hit-Ratios through a mapping function $f$, so that $SHR@k\approx HR@f(k)$, we demonstrate both theoretically and experimentally that the sampling top-$k$ Hit-Ratio provides an accurate approximation of its global (exact) counterpart, and can consistently predict the correct winners (the same as indicate by their corresponding global Hit-Ratios).

description: We investigate Kolmogorov wave turbulence in QCD or, in other words, we calculate the spectrum of gluons as a function of time, f_k(t), in the presence of a source which feeds in energy density in the infrared region at a constant rate. We find an early, an intermediate and a late time form for the gluon spectrum. Wave turbulence in QCD turns out to be somewhat different than the turbulence in the case of ϕ^4-type theories studied by Zakharov, L'vov and Falkovich. The hope is that a good understanding of QCD wave turbulence might lead to a better understanding of the instability problem in the early stages of the evolution after a heavy ion collision.

description: We investigate the late-time evolution of the Universe within a cosmological model in which dark matter and dark energy are identified with two interacting scalar fields. Using methods of qualitative analysis of dynamical systems, we identify all cosmological solutions of this model. We show that viable solutions -- in the sense that they correspond to a cosmic evolution in which a long enough matter-dominated era is followed by a current era of accelerated expansion -- can be found in several regions of the parameter space. These solutions can be divided into two categories, namely, solutions that evolve to a state of everlasting accelerated expansion, in which the energy density of the dark-matter field rapidly approaches zero and the evolution becomes entirely dominated by the dark-energy field, and solutions in which the stage of accelerated expansion is temporary and the ratio between the energy densities of dark energy and dark matter tends, asymptotically, to a constant nonzero value.

description: Interscale energy transfer in wall turbulence has been intensively studied in recent years, and both the forward (i.e. from larger to smaller scales) and reversed transfers of turbulent energy have been found whereas their corresponding physical phenomena have not been revealed. In the present study, we perform DNS of turbulent plane Couette flow with reduced-size computational domains, where either the streamwise or spanwise domain size is reduced to their minimal lengths, aiming at elucidating the role of scale interactions in each direction. Our computational results with the streamwise-minimal domain suggest that the interplays between streamwise-elongated streaks and vortices smaller than the streamwise minimal length are the essential scale interactions for both the inner and outer structures. We further show that these streamwise-independent and smaller-scale structures exchange energy through forward and reversed interscale energy transfers, and the reversed energy transfer maintains the energy production at larger scales. Based on the resemblance of the observed Reynolds-stress transport and the scenario of the self-sustaining cycle, we conjecture that the forward and reversed energy transfers mainly represent the streak instabilities and regeneration of streamwise vortices, respectively. Furthermore, the computation with the spanwise-minimal domain indicates that the interscale energy transfers observed by one-dimensional spanwise spectral analysis are likely related to individual dynamics of each inner and outer structure, rather than represent their interactions.

Έπειτα, αναλύονται τα αποτελέσματα της εμπειρικής ποσοτικής έρευνας, για την οποία συλλέχθηκαν ερωτηματολόγια από 103 εν ενεργεία εκπαιδευτικούς. Τα αποτελέσματα της έρευνας καταδεικνύουν, ότι η ύπαρξη φαινομένων οστρακισμού στον εργασιακό χώρο επηρεάζει αρνητικά την οργανωσιακή δέσμευση και την εργασιακή απόδοση των ατόμων, πλήττοντας ταυτόχρονα και την ικανοποίησή από τη ζωή τους.

description: This thesis examines the phenomenon of workplace ostracism, the extent to which employees perceive that they are ignored or excluded by their colleagues and the way this can affect aspects of their work – life balance. In particular, the study examines the effect of workplace ostracism on the organizational commitment, life satisfaction and job performance of the employees. Initially, this study begins with the literature review of workplace ostracism, by collecting information from Greek and mostly international literature and the other variables included in the research model. Furthermore, the study analyzes the results of the empirical quantitative survey conducted on 103 actively employed educators. According to the findings, the perceived ostracism in the workplace negatively affects employee’s organizational commitment and life satisfaction and consequently their job performance. The last part of this study presents the limitations of the research, suggestions for future research as well as some practical implications for managers of educational institutions so as to take preventive measures and be ready to respond to incidents related to workplace ostracism.

We obtain a formula that the shear viscosity is expressed by the quadratic form of the quark spectral function in the chiral symmetric phase. The magnitude of the shear viscosity is discussed assuming the Breit-Wigner type for the spectral function.

description: Quantum multifractality is a fundamental property of systems such as non-interacting disordered systems at an Anderson transition and many-body systems in Hilbert space. Here we discuss the origin of the presence or absence of a fundamental symmetry related to this property. The anomalous multifractal dimension $Δ_q$ is used to characterize the structure of quantum states in such systems. Although the multifractal symmetry relation \mbox{$Δ_q=Δ_{1-q}$} is universally fulfilled in many known systems, recently some important examples have emerged where it does not hold. We show that this is the result of two different mechanisms. The first one was already known and is related to Gaussian fluctuations well described by random matrix theory. The second one, not previously explored, is related to the presence of an algebraically localized envelope. While the effect of Gaussian fluctuations can be removed by coarse graining, the second mechanism is robust to such a procedure. We illustrate the violation of the symmetry due to algebraic localization on two systems of very different nature, a 1D Floquet critical system and a model corresponding to Anderson localization on random graphs.

Area evolution, bulk viscosity and entropy principles for dynamical horizons

description: We derive from Einstein equation an evolution law for the area of a trapping or dynamical horizon. The solutions to this differential equation show a causal behavior. Moreover, in a viscous fluid analogy, the equation can be interpreted as an energy balance law, yielding to a positive bulk viscosity. These two features contrast with the event horizon case, where the non-causal evolution of the area and the negative bulk viscosity require teleological boundary conditions. This reflects the local character of trapping horizons as opposed to event horizons. Interpreting the area as the entropy, we propose to use an area/entropy evolution principle to select a unique dynamical horizon and time slicing in the Cauchy evolution of an initial marginally trapped surface.

Exploiting a connection between random walks and quantum exclusion statistics that we previously established, we express this generating function in terms of grand partition functions for exclusion particles in a finite harmonic spectrum and present an alternative, simpler form for its logarithm that makes its polynomial structure explicit.

description: The objective of this diploma thesis relates to the issue of litigations concerning domain names, in association with the risk factor of a likelihood of confusion. The diploma thesis at hand aims to attempt to analyze those essential problems, that force proprietors of domain names and distinguishing marks, logos, and brand names into litigations. Initially, an introduction on this topic and the aforementioned “phenomenon” problem is provided. Following that, this diploma thesis is devided into four distinct chapters, the first of which is concerned with explaining the modus operandi and the registration procedure of a domain name. Then, the relation between domain names and the Law, as well as the legal nature of domain names, is analysed. Subsequently, an in-depth analysis on the issues relating to litigations over domain names, the bodies responsible for the resolution of such matters and certain procedural issues will be conducted. Finally, a report on certain juridical decrees of Greek courts regarding domain names, as well as the exposition of conclusions, will be laid out

Doch solange sich die Öffentlichen Bibliotheken diesen Herausforderungen stellen, ist die Frage des Medienformats im Jahr 2030 nebensächlich – denn das Format ist nur Mittel zum Zweck des eigentlichen Auftrags von Öffentlichen Bibliotheken: Für die Menschen und die Gesellschaft da zu sein, nicht für die Medien.

description: Der Beitrag stützt sich auf die Ausführungen der Publikation Alles immer smart: Kulturelle Bildung, Digitalisierung, Schule und auf die Befunde der repräsentativen Umfrage Bibliotheken / Digitalisierung / Kulturelle Bildung: Horizont 2018 des Rates für Kulturelle Bildung. Die Ergebnisse der Studie sind insofern richtungsweisend, als dass die Bibliotheksleitungen im Zuge der Digitalisierung vor der Aufgabe stehen, ihre Räume, Angebote und Vermittlungsformen für die Nutzerinnen und Nutzer zeitgemäß und zukunftsfähig zu gestalten. Die Befunde verdeutlichen, wie sich durch die Digitalisierung nicht nur die Angebote und Arbeitsweisen verändern, sondern auch wie deren institutionelles Selbstverständnis berührt wird. Am Beispiel der Bibliotheken zeigt sich in schöner Deutlichkeit, wie sich Analoges und Digitales gegenseitig stärken, statt sich zu verdrängen. So entstehen in den Öffentlichen Bibliotheken neuartige Kulturangebote, die neue Zielgruppen anziehen und neue Wege der Kulturvermittlung erfordern. Angesichts dessen kommt den Beschäftigten der Bibliotheken in mehrfacher Hinsicht eine zentrale Bedeutung zu, denn die Digitalisierung bringt neue Aufgaben und Anforderungen mit sich, die aus Sicht der Bibliotheksleitungen mit Nachqualifizierungen nicht erreicht werden können. Inwiefern in diesem Zusammenhang die Kooperationen mit nicht-bibliothekarischen Fachleuten relevant sind und zunehmen werden, ist eine der weiterführenden Fragen. Dieser Aspekt ist deshalb so bedeutsam, weil die überwiegende Mehrheit der Bibliotheksleitungen der Ansicht ist, dass Kulturelle Bildung einen essentiellen Beitrag leistet, um die Digitalisierung überhaupt sinnvoll zu erschließen und zu gestalten.

description: In the process of clinical diagnosis and treatment, the restricted mean survival time (RMST), which reflects the life expectancy of patients up to a specified time, can be used as an appropriate outcome measure. However, the RMST only calculates the mean survival time of patients within a period of time after the start of follow-up and may not accurately portray the change in a patient's life expectancy over time. The life expectancy can be adjusted for the time the patient has already survived and defined as the conditional restricted mean survival time (cRMST). A dynamic RMST model based on the cRMST can be established by incorporating time-dependent covariates and covariates with time-varying effects. We analysed data from a study of primary biliary cirrhosis (PBC) to illustrate the use of the dynamic RMST model. The predictive performance was evaluated using the C-index and the prediction error. The proposed dynamic RMST model, which can explore the dynamic effects of prognostic factors on survival time, has better predictive performance than the RMST model. Three PBC patient examples were used to illustrate how the predicted cRMST changed at different prediction times during follow-up. The use of the dynamic RMST model based on the cRMST allows for optimization of evidence-based decision-making by updating personalized dynamic life expectancy for patients.

description: Eight PbWO4 crystals produced for the electromagnetic calorimeter of the CMS experiment at LHC have been irradiated in a 20 GeV/c proton beam up to fluences of 5.4 E13 p/cm2. The damage recovery in these crystals, stored in the dark at room temperature, has been followed for over a year. Comparative irradiations with 60Co photons have been performed on seven other crystals using a dose rate of 1 kGy/h. The issue whether hadrons cause a specific damage to the scintillation mechanism has been studied through light output measurements on the irradiated crystals using cosmic rays. The correlation between light output changes and light transmission changes is measured to be the same for proton-irradiated crystals and for gamma-irradiated crystals. Thus, within the precision of the measurements and for the explored range of proton fluences, no additional, hadron-specific damage to the scintillation mechanism is observed.

description: In this paper, we study the problem of non-blockingness verification by tapping into the basis reachability graph (BRG). Non-blockingness is a property that ensures that all pre-specified tasks can be completed, which is a mandatory requirement during the system design stage. In this paper we develop a condition of transition partition of a given net such that the corresponding conflict-increase BRG contains sufficient information on verifying non-blockingness of its corresponding Petri net. Thanks to the compactness of the BRG, our approach possesses practical efficiency since the exhaustive enumeration of the state space can be avoided. In particular, our method does not require that the net is deadlock-free.

description: Σκοπός της παρούσας έρευνας ήταν να εξετάσει τις σχέσεις μεταξύ του κλίματος κινήτρων, της έλλειψης κινήτρων, της αυτοεικόνας και των συναισθημάτων κατά τη συμμετοχή των μαθητών/τριών β/θμιας εκπαίδευσης στο μάθημα της Φυσικής Αγωγής στο πλαίσιο της Θεωρίας του Αυτο-προσδιορισμού. Οι μαθητές/τριες του δείγματος συμπλήρωσαν ερωτηματολόγια για την εκτίμηση του κλίματος κινήτρων, της αυτοεικόνας, της έλλειψης κινήτρων, της ευχαρίστησης και της αναζωογόνησης στο μάθημα της Φυσικής Αγωγής. Τα αποτελέσματα της ανάλυσης παλινδρόμησης έδειξαν ότι το κλίμα αυτονομίας που διαμορφώνει ο/η καθηγητής/τρια Φυσικής Αγωγής στο μάθημα προβλέπει θετικά την αυτοεικόνα των μαθητών/τριών, ενώ η έλλειψη κινήτρων αρνητικά. Επίσης, η αυτοεικόνα επηρεάζει θετικά την ευχαρίστηση και την αναζωογόνηση των μαθητών/τριών στο μάθημα. Η έλλειψη κινήτρων δεν διαμεσολαβεί στην επίδραση του κλίματος κινήτρων στην αυτοεικόνα. Από τα αποτελέσματα προκύπτει ότι το κλίμα αυτονομίας που διαμορφώνει ο/η καθηγητής/τρια Φυσικής Αγωγής στο μάθημα, μπορεί να αποτελέσει μια αποτελεσματική πρακτική στη βελτίωση της αυτοεικόνας των μαθητών/τριών και στην ανάπτυξη θετικών συναισθημάτων κατά τη συμμετοχή τους σε αυτό
description: The purpose of this research was to examine the relationship between motivation, amotivation, self-image, and emotions in the participation of pupils in the Physical Education lesson in the context of the Self-determination Theory. Sample students completed questionnaires to assess the motivation, self-image, amotivation, enjoyment, and vitality in Physical Education lessons. The results of the regression analysis showed that the climate of autonomy formed by the physical education teacher in the lesson positively predicts the self-image of the pupils while the amotivation negatively. Also, the self-image affects positively the enjoyment and vitality of students in the lesson. Amotivation does not mediates the effect of the motivational climate on the self-image. The results show that the climate of autonomy formed by the Physical Education teacher in the lesson can be an effective practice in improving students' self-image and in developing positive emotions when participating in it

description: Η επιτυχία της σχολικής ένταξης εξαρτάται από τη γνώση, τη στάση, την κατανόηση, την αποδοχή αλλά και τον σεβασμό στη διαφορετικότητα. Η αλλαγή των στάσεων των παιδιών με τυπική ανάπτυξη, σχετικά με την έννοια της αναπηρίας, αλλά και η καλλιέργεια της ενσυναίσθησης κρίνεται αναγκαία για την αποδοχή των παιδιών με αναπηρία. Σκοπός της έρευνας ήταν η αξιολόγηση του επιπέδου κατανόησης της αναπηρίας και της ενσυναίσθησης, καθώς και η εφαρμογή ενός πρότυπου προγράμματος αφήγησης παραμυθιών, σχετικών με την αναπηρία και την ενσυναίσθηση σε συνδυασμό με θεατρικό παιχνίδι. Στη μελέτη πήραν μέρος 32 μαθητές, ηλικίας 7 ετών, από ένα Δημοτικό σχολείο της πόλης των Σερρών. Οι μαθητές χωρίστηκαν σε 2 ομάδες, όπου η ομάδα παρέμβασης παρακολούθησε το πρότυπο πρόγραμμα διάρκειας 14 εβδομάδων και συχνότητας 3 φορές εβδομαδιαίως, ενώ η ελέγχου ακολούθησε το τυπικό πρόγραμμα του σχολείου. Από τα αποτελέσματα της έρευνας φάνηκε ότι το πρόγραμμα παρέμβασης είχε σημαντική επίδραση σε όλες τις μεταβλητές που αξιολογήθηκαν. Συμπερασματικά, διαπιστώνεται ότι η εφαρμογή κατάλληλα δομημένων προγραμμάτων πρώιμης παρέμβασης μπορεί να συμβάλλει στην αποδοχή της αναπηρίας και στην καλλιέργεια της ενσυναίσθησης
description: The success of school integration depends on knowledge, attitude, understanding, acceptance, as well as respect for diversity. Changing the attitudes of children with typical development about disability, as well as enhancing empathy, is considered necessary for the acceptance of children with disabilities. This study aims at determining the effect of a storytelling and theatrical play program on the enhancement of empathy and the acceptance of disability in first grade school children. The study included 32 students, 7-year-olds who attended a primary school in the city of Serres. They were divided into 2 groups. The intervention group attended a 14-week program for 3 times a week. The control group attended the typical schedule of the school. The results of the study indicated that the intervention program had a significant impact on all the variables assessed. In conclusion, the implementation of appropriate structured early intervention programs can contribute to accepting disability and fostering empathy
"Anomaly" in n=infinity Alday-Maldacena Duality for Wavy Circle

description: If the Alday-Maldacena version of string/gauge duality is formulated as an equivalence between double loop and area integrals a la arXiv: 0708.1625, then this pure geometric relation can be tested for various choices of n-side polygons. The simplest possibility arises at n=infinity, with polygon substituted by an arbitrary continuous curve. If the curve is a circle, the minimal surface problem is exactly solvable. If it infinitesimally deviates from a circle, then the duality relation can be studied by expanding in powers of a small parameter. In the first approximation the Nambu-Goto (NG) equations can be linearized, and the peculiar NG Laplacian plays the central role. Making use of explicit zero-modes of this operator (NG-harmonic functions), we investigate the geometric duality in the lowest orders for small deformations of arbitrary shape lying in the plane of the original circle. We find a surprisingly strong dependence of the minimal area on regularization procedure affecting "the boundary terms" in minimal area. If these terms are totally omitted, the remaining piece is regularization independent, but still differs by simple numerical factors like 4 from the double-loop integral which represents the BDS formula so that we stop short from the first non-trivial confirmation of the Alday-Maldacena duality. This confirms the earlier-found discrepancy for two parallel lines at n=infinity, but demonstrates that it actually affects only a finite number (out of infinitely many) of parameters in the functional dependence on the shape of the boundary, and the duality is only slightly violated, which allows one to call this violation an anomaly.

description: Dielectric particles in weakly conducting fluids rotate spontaneously when subject to strong electric fields. Such Quincke rotation near a plane electrode leads to particle translation that enables physical models of active matter. Here, we show that Quincke rollers can also exhibit oscillatory dynamics, whereby particles move back and forth about a fixed location. We explain how oscillations arise for micron-scale particles commensurate with the thickness of a field-induced boundary layer in the nonpolar electrolyte. This work enables the design of colloidal oscillators.
