description: We test the hypothesis that globular clusters form in supergiant molecular clouds within high-redshift galaxies. Numerical simulations demonstrate that such large, dense, and cold gas clouds assemble naturally in current hierarchical models of galaxy formation. These clouds are enriched with heavy elements from earlier stars and could produce star clusters in a similar way to nearby molecular clouds. The masses and sizes of the model clusters are in excellent agreement with the observations of young massive clusters. Do these model clusters evolve into globular clusters that we see in our and external galaxies? In order to study their dynamical evolution, we calculate the orbits of model clusters using the outputs of the cosmological simulation of a Milky Way-sized galaxy. We find that at present the orbits are isotropic in the inner 50 kpc of the Galaxy and preferentially radial at larger distances. All clusters located outside 10 kpc from the center formed in the now-disrupted satellite galaxies. The spatial distribution of model clusters is spheroidal, with a power-law density profile consistent with observations. The combination of two-body scattering, tidal shocks, and stellar evolution results in the evolution of the cluster mass function from an initial power law to the observed log-normal distribution. However, not all initial conditions and not all evolution scenarios are consistent with the observed mass function.

description: A single-parameter family of covariant gauge fixing conditions in bosonic string field theory is proposed. It is a natural string field counterpart of the covariant gauge in the conventional gauge theory, which includes the Landau gauge as well as the Feynman (Siegel) gauge as special cases. The action in the Landau gauge is largely simplified in such a way that numerous component fields have no derivatives in their kinetic terms and appear in at most quadratic in the vertex.

Marginalized Bodies of Imagined Futurescapes : Ableism and Heteronormativity in Science Fiction

description: This article aims to contribute to an understanding of marginalized bodies in science fiction narratives by analyzing how physical disability and homosexuality/bisexuality have been depicted in popular science fiction film and television. Specifically, it analyzes what types of futures are evoked through the exclusion or inclusion of disability and homo/bisexuality. To investigate these futurescapes, in for example Star Trek and The Handmaid’s Tale, the paper uses film analysis guided by the theoretical approach of crip/queer temporality mainly in dialogue with disability/crip scholar Alison Kafer. Although narratives about the future in popular fiction occasionally imagines futures in which disability and homo/bisexuality exist the vast majority do not. This article argues that exclusion of characters with disabilities and homo/bisexual characters in imagined futures of science fiction perpetuate heteronormative and ableist normativity. It is important that fictional narratives of imagined futures do not limit portrayals to heterosexual and able-bodied people but, instead, take into account the ableist and heteronormative imaginaries that these narratives, and in extension contemporary society, are embedded in. Moreover, it is argued that in relation to notions of progression and social inclusion in imagined futurescapes portrayals of homo/bisexuality and disability has been used as narrative devices to emphasis “good” or “bad” futures. Furthermore, homo/bisexuality has increasingly been incorporated as a sign of social inclusion and progression while disability, partly due to the perseverance of a medical understanding of disability, instead is used as a sign of a failed future. However, the symbolic value ascribed to these bodies in stories are based on contemporary views and can thus change accordingly. To change the way the future is envisioned requires challenging how different types of bodies, desires, and notions of normativity are thought about. Sometimes imaginary futures can aid in rethinking and revaluating these taken-for-granted notions of normativity.

description: The present thesis attempts to review, and apply, the methods used for estimating orthometric heights in topographic practice. The main objective is to study the accuracy of determination of orthometric heights using the process of levelling with GNSS receivers. As a generalization of all the methods that will be presented, the method of integrated geodesy (or least square collocation) offers the significant advantage of simultaneous processing of all types of geodetic data, and constitutes the central method for solving each one of the different cases presented in the study. The study network is installed and measured by GPS receivers in the wider area of the Prefecture of Thessaloniki and five resolution cases were attempted to assess the accuracy of the results.

description: The generalized Weierstrass representation is used to analyze the asymptotic behavior of a constant mean curvature surface that arises locally from an ordinary differential equation with a regular singularity. We prove that a holomorphic perturbation of an ODE that represents a Delaunay surface generates a constant mean curvature surface which has a properly immersed end that is asymptotically Delaunay. Furthermore, that end is embedded if the Delaunay surface is unduloidal.

description: We demonstrate perfect coherence preservation in an atom interferometer perturbed by kicks from off-resonant standing wave pulses. Under most conditions, the decoherence induced by the pulses reduces the signal; however, the coherence is perfectly preserved when the kicking period is equal to the rational fraction of the inverse atomic recoil frequency, independent of the number or the randomness of the strength of the applied kicks. The width narrowing of coherence revival as a function of increasing kick number and strength provides a new accurate measurement of the recoil frequency.

description: CEA-Gramat studies the sensitivity of energetic materials to enhance their security and reliability. The conditions leading to the initiation of an explosive must be understood to control its sensitivity. According to the hot spots theory, the shock initiation of heterogeneous explosives is related to their microstructure: the shock interacts with the heterogeneities of the microstructure (pores and inclusions, morphology of grains and fragments, debonding, etc.) and creates local deposits of energy. To describe these hot spots, energetic materials have to be modeled at a scale allowing the discretization of their microstructure: the mesoscale. Micro-computed tomographies of energetic materials are done at CEA-Gramat and analyzed to build geometric models used in finite element simulations. Two kinds of models are studied:-Real models are directly built on the real microstructures extracted from micro-computed tomographies.-Virtual models are based on the same microstructures but simplified to study independently the effects of microstructural parameters (granulometry, porosity, filler content{\ldots}) on the creation of hot spots. Compositions based on different kind of RDX particles in an inert binder are studied through numerical simulation. The influence of particle shape on the inert shock response is investigated at the mesoscale. Local heterogeneities of pressure and temperature fields appear intimately related to the morphological properties of the microstructures. Particles with sharp edges create more hot spots than spherical particles.

description: The COVID-19 pandemic has resulted in dramatic changes to the daily habits of billions of people. Users increasingly have to rely on home broadband Internet access for work, education, and other activities. These changes have resulted in corresponding changes to Internet traffic patterns. This paper aims to characterize the effects of these changes with respect to Internet service providers in the United States. We study three questions: (1)How did traffic demands change in the United States as a result of the COVID-19 pandemic?; (2)What effects have these changes had on Internet performance?; (3)How did service providers respond to these changes? We study these questions using data from a diverse collection of sources. Our analysis of interconnection data for two large ISPs in the United States shows a 30-60% increase in peak traffic rates in the first quarter of 2020. In particular, we observe traffic downstream peak volumes for a major ISP increase of 13-20% while upstream peaks increased by more than 30%. Further, we observe significant variation in performance across ISPs in conjunction with the traffic volume shifts, with evident latency increases after stay-at-home orders were issued, followed by a stabilization of traffic after April. Finally, we observe that in response to changes in usage, ISPs have aggressively augmented capacity at interconnects, at more than twice the rate of normal capacity augmentation. Similarly, video conferencing applications have increased their network footprint, more than doubling their advertised IP address space.

We report the first ever detection of the SiO molecule in a Type IIP supernova. Together with the detection of the CO fundamental, this is an exciting finding as it may signal the onset of dust condensation in the ejecta. From a wealth of fine-structure lines we provide abundance estimates for stable Ni, Ar, and Ne which, via spectral synthesis, may be used to constrain nucleosynthesis models.

description: We study vacuum structure of N=1 supersymmetric quiver gauge theories which can be realized geometrically by D brane probes wrapping cycles of local Calabi-Yau three-folds. In particular, we show that the A_2 quiver theory with gauge group U(N_1) \times U(N_2) with N_1 / 2 < N_2 < 2N_1 / 3 has a regime with an infrared free description that is partially magnetic and partially electric. Using this dual description, we show that the model has a landscape of inequivalent meta-stable vacua where supersymmetry is dynamically broken and all the moduli are stabilized. Each vacuum has distinct unbroken gauge symmetry. B-terms generated by the supersymmetry breaking give rise to gaugino masses at one-loop, and we are left with the bosonic pure Yang-Mills theory in the infrared. We also identify the supersymmetric vacua in this model using their infrared free descriptions and show that the decay rates of the supersymmetry breaking vacua into the supersymmetric vacua can be made parametrically small.

description: Gamma-ray continuum at > 10 MeV photon energy yields information on > 0.2 - 0.3 GeV/nucleon ions at the Sun. We use the general-purpose Monte Carlo code FLUKA (FLUktuierende KAskade) to model the transport of ions injected into thick and thin target sources, the nuclear processes that give rise to pions and other secondaries and the escape of the resulting photons from the atmosphere. We give examples of photon spectra calculated with a range of different assumptions about the primary ion velocity distribution and the source region. We show that FLUKA gives results for pion decay photon emissivity in agreement with previous treatments. Through the directionality of secondary products, as well as Compton scattering and pair production of photons prior to escaping the Sun, the predicted spectrum depends significantly on the viewing angle. Details of the photon spectrum in the 100 MeV range may constrain the angular distribution of primary ions and the depths at which they interact. We display a set of thick-target spectra produced making various assumptions about the incident ion energy and angular distribution and the viewing angle. If ions are very strongly beamed downward, or ion energies do not extend much above 1 GeV/nucleon, the photon spectrum is highly insensitive to details of the ion distribution. Under the simplest assumptions, flares observed near disc centre should not display significant radiation above 1 GeV photon energy. We give an example application to Fermi Large Area Telescope data from the flare of 12 June 2010.

description: Land cover changes although acting locally are considered as a key factor for global environmental change. Nowadays drivers theory that holds land use changes for a key direct driver, is acknowledged as the best to drive Socio-Ecological systems to sustainable development. Since 2000 that the drivers theory slowly began to shape, there isn't any assessment found on drivers used in E.U. scale for all land cover changes. While there are many references focusing in methodolocical problems that need to be covered when applied. This work covers the void of an assessment in a significant part of E.U. in terms of drivers change for changes during 2000-2006, using socio-economic drivers as indirect and land cover changes as direct driver. While specifically addressing the following methodological problems: a) selecting a comparable drivers set coming from different sciences, b) recognising the best way of combining them and c) finding compatible driver's scale in order to export results that would be useful in decision making and policy planning. The methodology was applied in all land cover changes and results are exported for all, discussion though is preferred to focus on terrestrial ecosystems excluding wetlands and aquatic ecosystems.

description: A detailed zero-field and transverse-field muon spin relaxation/rotation ($μ$SR) experiemnts have been carried out on the recently discovered non-centrosymmetric superconductor W$_3$Al$_2$C to speculate about its superconducting ground state. Bulk nature of superconductivity below 7.6 K is confirmed through magnetization measurements. No change in the $μ$SR spectra collected above and below $T_c$ is visible, ruling out the possibility of spontaneous magnetic field below $T_c$. This confirms that time-reversal symmetry is preserved for W$_3$Al$_2$C upon entering in the superconducting ground state. Temperature dependent superfluid density [$ρ_s(T)$], which directly reflects the superconducting gap symmetry is obtained by the analysis of spectra obtained from the transverse-field $μ$SR experiments. Despite a non-centrosymmetric structure, W$_3$Al$_2$C adopts a fully gaped spin-singlet superconducting ground state with a zero temperature value of gap $Δ_0$ = 1.158(8) meV with gap-to-$T_c$ ratio 2$Δ_0/k_BT_c\approx$3.54, classifying this material as a weakly-coupled superconductors.

description: Dyslexia is defined as a disability that primarily affects reading and writing. Internationally, the number of dyslexic students entering higher education is on the rise. Many countries have developed support services and teaching prac¬tices to accommodate dyslexic students’ educational needs. In Greece, research on dyslexia in higher education is non-existent. The purpose of this study is to define the incidence of dyslexia among the Greek student population and to examine dyslexic students’ age, gender and major field of study. Data were collected from all Greek public institutions of higher education (n=32) with a total of406 departments. The existing provisions for dyslexic students and the higher education institutions’ practices were also examined. The results of the study are discussed in the light of inclusive education and equality of oppor¬tunities for students with dyslexia.

description: The aim of the present master – thesis was the study of the abnormal development of a contractual relationship, specifically of a works contract. The main issue was the employer’s protection and the corresponding liability of the contractor in case the project displays actual defects or lack of the agreed qualities, which is regulated by the provision of the articles 687 – 690 C.C. In the first chapter, there was an introduction to the obligations of the contractor and the general liability he incurs in case he fails to comply with them. Then, an analysis in the definition of the terms “actual defects” and “agreed qualities” followed and there was a conceptual distinction between those terms and the relevant ones. Afterwards, there was a specialization of the contractor’s liability in case the project displays actual defects or there is a lack of the agreed qualities. In particular, there was an analysis of the rights that the articles 687 and the following of the Civil Code provide for the employer and we addressed the issue of the overlapping of the former rights with the general provisions of the contract law (law of obligations) regarding the non compliance with the obligation in general. Finally, there was a description of the cases in which the contractor is exempted from his liability.

description: Machine learning systems (MLSys) are emerging in the Internet of Things (IoT) to provision edge intelligence, which is paving our way towards the vision of ubiquitous intelligence. However, despite the maturity of machine learning systems and the IoT, we are facing severe challenges when integrating MLSys and IoT in practical context. For instance, many machine learning systems have been developed for large-scale production (e.g., cloud environments), but IoT introduces additional demands due to heterogeneous and resource-constrained devices and decentralized operation environment. To shed light on this convergence of MLSys and IoT, this paper analyzes the trade-offs by covering the latest developments (up to 2020) on scaling and distributing ML across cloud, edge, and IoT devices. We position machine learning systems as a component of the IoT, and edge intelligence as a socio-technical system. On the challenges of designing trustworthy edge intelligence, we advocate a holistic design approach that takes multi-stakeholder concerns, design requirements and trade-offs into consideration, and highlight the future research opportunities in edge intelligence.

description: The Catholic Church embarked upon an ambitious project of property development in the nineteenth century that transformed the Irish built environment and landscape. People responded energetically to fundraising drives for churches, convents, monasteries and welfare-focused institutions. The acquisition of significant property and substantial capital by the Irish Catholic Church was a major source of its power, which continued into independent Ireland. Much of this wealth came to the Catholic Church through bequests, donations, and returns on investment, which were managed by the relevant dioceses and orders. This article focuses on the episcopacy of Archbishop William Walsh of Dublin during the 1880s and 1890s to understand the way in which the management of the archdiocese of Dublin’s financial resources shaped the social, economic, and political development of Ireland’s capital city. By focusing on the management of one of the most significant bequests under Walsh’s supervision – the Egan Bequest – a complex story of religion, investment and infrastructure building is revealed. This activity helped produce a model of investor capitalism that shaped Dublin in ways that remain contested to this day.

description: New gauge fixing condition with single gauge parameter proposed by the authors is applied to the level truncated analysis of tachyon condensation in cubic open string field theory. It is found that the only one real non-trivial extremum persists to appear in the well-defined region of the gauge parameter, while the other solutions are turned out to be gauge-artifacts. Contrary to the previously known pathology in the Feynman-Siegel gauge, tachyon potential is remarkably smooth enough around Landau-type gauge.

description: Στην παρούσα μελέτη επιχειρείται η ευσύνοπτη και κατά το δυνατόν περιεκτική παρουσίαση και ερμηνεία της παραβολής του τελώνη και Φαρισαίου. Αρχικά δίνεται ο ορισμός της λέξης «παραβολή» και παρουσιάζεται η χρήση της στην Καινή Διαθήκη. Στη συνέχεια πραγματοποιείται η παρουσίαση της λατρείας στον Ναό των Ιεροσολύμων. Γίνεται συνοπτική περιγραφή της αρχιτεκτονικής των Ναών: του Σολομώντα, του Ζοροβάβελ και του Ηρώδη. Αναφέρονται πληροφορίες για το ιουδαϊκό ιερατείο της εποχής εκείνης και γίνεται παρουσίαση των μεγάλων γιορτών του Ιουδαϊσμού. Στη συνέχεια περιγράφεται αναλυτικά η τάξη των Φαρισαίων και των τελώνων στην Ευαγγελική παράδοση. Εξετάζεται η συνάφεια του κειμένου της παραβολής του τελώνη και Φαρισαίου και ερμηνεύεται κατά στίχο. Το κήρυγμα της παραβολής είναι η προσευχή και η ταπείνωση. Ο άνθρωπος πρέπει να προσεύχεται με συντριβή και να διακατέχεται από ταπεινότητα για να είναι άξιος να δεχτεί το θείο έλεος που παρέχεται με το αίμα του Χριστού. Τέλος πραγματοποιείται η ομιλητική επεξεργασία της περικοπής από τους Πατέρες, που ανέφεραν και ερμήνευσαν σε κάποια ομιλία τους την παραβολή του τελώνη και Φαρισαίου. Χρησιμοποιώντας οι Πατέρες τη γλώσσα της εποχής τους, καθοδηγούν τους ακροατές τους να αισθανθούν από τη μια την ανεπάρκεια και την αμαρτωλότητά τους και από την άλλη την ευσπλαχνία του Θεού στους αμαρτάνοντες και στους μετανοούντες Οι Πατέρες τονίζουν την ανάγκη της ηθικής και οντολογικής αναγέννησης του ανθρώπου δια του Αγίου Πνεύματος.
description: In the present study, a concise and comprehensive presentation and interpretation of the parable of the tax collector and Pharisee is attempted. To begin with, the definition of the ''parable'' is given and the use of it in the New Testament is presented. Then the presentation of worship in the Temple of Jerusalem takes place. A synoptic description of the architecture of the temples of Solomon, Zerubbabel's and Herod is given. We are informed about Jewish priesthood of that time and the major festivals of Judaism are introduced. In addition, the class of the Pharisees and of the tax collectors in the Evangelical tradition is described in detail. The relevance of the text of the parable of the tax collector and Pharisee is examined and is interpreted in verse. The preaching of the parable is prayer and humiliation. Man must pray with contrition and be filled with humility to be worthy to receive the divine mercy that comes with the blood of Christ. Finally it is held the talkative of the verse of the Fathers, who reported and interpreted on one of their sermons the parable of the tax collector and Pharisee. Using the language of their time the Fathers guide listeners to feel on the one hand the deficiency and their sinfulness and on the other hand the mercy of God to the sinners and penitents. The Fathers stress the need for ethical and ontological regeneration of man through the Holy Spirit.
Optical variability power spectrum analysis of blazar sources on intranight timescales

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

description: We report the first results of a systematic investigation to characterize blazar variability power spectral densities (PSDs) at optical frequencies using densely sampled (5--15 minutes integration time), high photometric accuracy ($\lesssim$0.2--0.5\%) R-band intranight light curves, covering timescales ranging from several hours to $\sim$15\,minutes. Our sample consists of 14 optically bright blazars, including nine BL Lacertae objects (BL Lacs) and five flat-spectrum radio quasars (FSRQs) which have shown statistically significant variability during 29 monitoring sessions. We model the intranight PSDs as simple power--laws and derive the best-fit slope along with uncertainty using the `power spectral response' method. Our main results are the following: (1) on 19 out of 29 monitoring sessions, the intranight PSDs show an acceptable fit to simple power-laws at the rejection confidence $\leq$ 90\%; (2) for these 19 instances, the PSD slopes show a large range from 1.4 to 4.0, consistent with statistical characters of red (slope$\sim$2) and black (slope$\geq$3) noise stochastic processes; (3) the average PSD slopes for the BL Lacs and FSRQs are indistinguishable from one another; (4) the normalization of intranight PSDs for individual blazar sources which were monitored on more than one occasion turns out to be consistent with one another with a few exceptions. The average PSD slope, 2.9$\pm$0.3 (1$σ$ uncertainty) is steeper than the red-noise type character of variability found on longer timescales (many decades to days), indicative of a cutoff in the variability spectrum on timescales around a few days at the synchrotron frequencies of the emission spectrum.

"Will We be Tested on This?" : Schoolgirls, Neoliberalism and the Comic Grotesque in Swedish Contemporary Youth Theatre

description: This article is based on an ethnographic participation study of the production of a play called All about the ADHD and A+ Children of Noisy Village (ännu mer om alla vi ADHD- och MVG-barn i Bullerbyn) staged at one of Sweden’s most prominent playhouses for children’s and youth theatre: ung scen/öst. Within the familiar setting of the classroom, the play takes on the challenging task of questioning and scrutinizing the complex and tangled situation of contemporary neoliberal ideas and practices, their connections to capitalism and their impact on everyday school-life. This in front of an audience consisting mainly of individuals who were not even born at the time when the political map was radically re-drawn in Berlin in 1989, and who have grown up during a period when neoliberal governance has gained increasing influence in Swedish culture and society. The play mediates its dense, political content and its descriptions of teenagers’ everyday lives through a large portion of good old-fashioned entertainment, with music, singing and bizarre, laughter-provoking situations. The main research question to be answered in the article is: In what ways are the abstract contemporary economic-political manifestations of power and govern-ance expressed in this good-humored play for youth, and how can this be read from a feminist perspective? Hence, the article circles around three nodes that intersect in various ways: theatre, economic-political issues and feminist perspectives. The theoretical framework of the article is primarily based on a merger between, on the one hand, feminist social science and, on the other, feminist cultural analysis.

description: Unmanned aerial vehicles have been demonstrated successfully in a variety of tasks, including surveying and sampling tasks over large areas. These vehicles can take many forms. Quadrotors' agility and ability to hover makes them well suited for navigating potentially tight spaces, while fixed wing aircraft are capable of efficient flight over long distances. Hybrid aerial vehicles (HAVs) attempt to achieve both of these benefits by exhibiting multiple modes; however, morphing HAVs typically require extra actuators which add mass, reducing both agility and efficiency. We propose a morphing HAV with folding wings that exhibits both a quadrotor and a fixed wing mode without requiring any extra actuation. This is achieved by leveraging the motion of a bistable mechanism at the center of the aircraft to drive folding of the wing using only the existing motors and the inertia of the system. We optimize both the bistable mechanism and the folding wing using a topology optimization approach. The resulting mechanisms were fabricated on a 3D printer and attached to an existing quadrotor frame. Our prototype successfully transitions between both modes and our experiments demonstrate that the behavior of the fabricated prototype is consistent with that of the simulation.

description: In 1942 I. J. Schoenberg proved that a function is positive definite in the unit sphere if and only if this function is a positive linear combination of the Gegenbauer polynomials. In this paper we extend Schoenberg's theorem for multivariate Gegenbauer polynomials. This extension derives new positive semidefinite constraints for the distance distribution which can be applied for spherical codes.

description: We show that one may view the self and the distinct part of the van Hove dynamic correlation function of a simple fluid as the one-body density distributions of a binary mixture that evolve in time according to dynamical density functional theory. For a test case of soft core Brownian particles the theory yields results for the van Hove function that agree quantitatively with those of our Brownian dynamics computer simulations. At sufficiently high densities the free energy landscape underlying the dynamics exhibits a barrier as a function of the mean particle displacement, shedding new light on the nature of glass formation. For hard spheres confined between parallel planar walls the barrier height oscillates in-phase with the local density, implying that the mobility is maximal between layers, which should be experimentally observable in confined colloidal dispersions.

description: This paper applies discourse analysis to study the nature of interactions in a leaming-in-groups (LIG) approach, where students work together, discuss and provide explanations of some physical phenomena. The methodology inte¬grates qualitative and quantitative approaches. The coding process was carried out with the aid of ATLAS software and it followed a qualitative approach, where the categories were not predetermined, but they emerge from the process of analysis. The resulted codes were organized into two categories: The cog¬nitive interactions, which could be simple or higher order cognitive interactions and the social interactions. The cognitive content of the discourses along with two features, namely the diversity and the relative activity were shown to be characteristics of the effective groups. Moreover, some dynamical patterns of
discourse were revealed and correlated with the interactive-process effective¬ness. Finally, discussion is provided about LIG approach, group dynamics and methodological issues for social science research.

description: This article examines different types of queer spaces in contemporary Shanghai together with the various same-sex subjects that inhabit these spaces. In doing so, it discusses the impact of transnational capitalism, the nation state and local histories on the construction of urban spaces and identities. Combining queer studies and urban ethnography, this article points to the increasing social inequalities hidden behind the notion of urban cosmopolitanism created by the deterritorializing and meanwhile territorializing forces of transnational capital and the state. It also sheds light on how these various identities and spaces are lived and experienced by ordinary people, as well as possible ways of resistance to the dominant narratives.
