description: (abridged) A detailed study of the blue supergiant UIT005 (B2-2.5Ia+) in M33 is presented. The results of our quantitative spectral analysis indicate that the star is a very luminous, log(L/Lsun)~5.9 dex, and massive, M~50 Msun, object, showing a very high nitrogen-to-oxygen ratio in its surface (N/O~8, by mass). Based on the derived Mg and Si abundances, we argue that this high N/O ratio cannot be the result of an initial low O content due to its location on the disk of M33, known to present a steep metallicity gradient. In combination with the He abundance, the most plausible interpretation is that UIT005 is in an advanced stage of evolution, showing in its surface N enrichment and O depletion resulting from mixing with CNO processed material from the stellar interior. A comparison with the predictions of current stellar evolutionary models indicates that there are significant discrepancies, in particular with regard to the degree of chemical processing, with the models predicting a much lower degree of O depletion than observed. At the same time, the mass-loss rate derived in our analysis is an order of magnitude lower than the values considered in the evolutionary calculations. Based on a study of the surrounding stellar population and the nearby cluster NGC588, using WFPC2 photometry, we suggest that UIT005 could be in fact a runaway star from this cluster.

Questione di... punti di vista. Attività sul coordinamento di punti di vista in un primo ciclo della scuola elementare
Creators: name: Bozzotti, Pamela

description: A partire dai pionieristici lavori di Piaget, sono molte le ricerche che hanno messo in luce le difficoltà da parte dei bambini ad assumere e immaginare punti di vista diversi dal proprio e di coordinare e integrare tali punti di vista. Questa capacità è legata alla più generale competenza degli allievi di “vedere” in geometria. Attraverso questa ricerca, in una classe del primo ciclo della scuola elementare, è stato sperimentato un percorso volto a favorire proprio tale capacità. Durante la sperimentazione, gli allievi hanno avuto modo di muoversi e agire in diversi tipi di spazio (dal microspazio del banco e del foglio al mesospazio dell’aula e della palestra), confrontarsi con artefatti di diversa natura e mobilitare registri semiotici e rappresentativi differenti. I dati raccolti, soprattutto sotto forma di rappresentazioni grafiche dei bambini, sono stati analizzati sia in maniera quantitativa che qualitativa, in relazione alle difficoltà e ai processi attivati. In questo senso, sono stati scelti tre casi significativi di cui si è svolta, nel dettaglio, l’analisi dell’evoluzione delle produzioni grafiche. Dai dati raccolti e dalle analisi è emerso che la maggior parte degli allievi ha conosciuto un’evoluzione positiva delle proprie competenze e che le scelte didattiche adottate sono state dunque efficaci per migliorare la capacità degli allievi di concettualizzare e coordinare diversi punti di vista.

description: The superfluid to normal fluid transition of dipolar bosons in two dimensions is studied throughout the whole density range using path integral Monte Carlo simulations and summarized in the phase diagram. While at low densities, we find good agreement with the universal results depending only on the scattering length $a_s$, at moderate and high densities, the transition temperature is strongly affected by interactions and the elementary excitation spectrum. The results are expected to be of relevance to dipolar atomic and molecular systems and indirect excitons in quantum wells.

Πρόκειται για σχετικά νέα ιδρύματα με νέο περιεχόμενο, καθώς οι συλλογές τους ξεκινάνε από τον 19ο αιώνα. Στην Ελλάδα, το Εθνικό Οπτικοακουστικό Αρχείο (ΕΟΑ) δημιουργήθηκε το 2006 προκειμένου να καλύψει το κενό που υπήρχε στη διαχείριση των οπτικοακουστικών αρχείων. Καταργήθηκε με υπουργική απόφαση το 2011, ενώ η δραστηριότητά του και ο επιδιωκόμενος σκοπός του μεταφέρθηκαν στην Ελληνική Ραδιοφωνία-Τηλεόραση (ΕΡΤ). Στα τέλη του 2015 συστάθηκε το Εθνικό Κέντρο Οπτικοακουστικών Μέσων και Επικοινωνίας (ΕΚΟΜΕ), το οποίο καθίσταται σήμερα ο εθνικός κόμβος αναφοράς γύρω από την οπτικοακουστική παραγωγή της Ελλάδας. Το Institut national de l'audiovisuel (INA) είναι ο επίσημος φορέας οπτικοακουστικών αρχείων της Γαλλίας, που δημιουργήθηκε το 1974 και είναι υπεύθυνο για τη συλλογή, τη συντήρηση και τη διάθεση των γαλλικών οπτικοακουστικών συλλογών. Αποτελεί έναν πρότυπο φορέα διαχείρισης οπτικοακουστικού περιεχομένου λειτουργώντας την ίδια στιγμή ως το εθνικό αποθετήριο οπτικοακουστικού υλικού της Γαλλίας. Μέσα από τη συγκριτική μελέτη των ευρωπαϊκών αυτών εθνικών φορέων διαχείρισης οπτικοακουστικών αρχείων η εργασία αποσκοπεί να διερευνήσει τους λόγους που επηρεάζουν τη λειτουργία τους και να εξετάσει ποιος είναι ο ρόλος τους στη διαχείριση του οπτικοακουστικού περιεχομένου.
Wayfinding peace : museums in conflict zones
Creators: name: Baker, Kimberly Ann
Publisher: name: University of British Columbia

description: The study Wayfinding Peace: Museums in Conflict Zones reconsiders the approaches peace museums have taken when promoting peace by drawing on the ways ethnographer Sultan Somjee and the Community Peace Museums Heritage Foundation (CPMHF) in Kenya utilize the African humanist philosophy of Utu in their museum practices in conflict zones. The CPMHF is a collective of 16 rural museums in conflict-prone areas. They often lack governmental support and resources and operate on minimal budgets. Through a series of fieldwork journeys, the research illuminates Somjee’s experiences of developing the community peace museums in unstable political and social situations. Overall, the dissertation highlights the 26-year history of the CPMHF using Indigenous peace heritage traditions to resolve contemporary conflict and build peaceful civil society relations. Moreover, the study suggests cultural heritages maintained in traditions of peacebuilding can contribute to bonding communities at large in several ways: 1) sustain children and youth's connection to their Indigenous culture by exploring their peace traditions through art education; 2) provide protection and conservation of biological heritage; 3) offer culturally specific approaches for reconciliation among conflicting minority and majority ethnic groups through agency. The study offers the cultural workers of peace museums an opportunity to learn alternative peace museum themes and approaches based on culture.
IT TAKES A VILLAGE: THE JOURNEY OF THE SMALL TOWN BUSINESS OWNER

description: This study examined female small business owners and their experience starting and maintaining a business. The sample consisted of 10 women, ages 26-58, residing in Kern County, CA with communities of 15,000 people and less. Being in a small town with few locally owned stores, there is more than enough space to sprout a new business venture. Having the luxury to work from home and create their own hours also has been of appeal to many women, especially mothers. However, this study is looking to reveal how access to the ‘right’ resources and lack of prior business experience may be the biggest detriments to female owned small businesses in such small communities. The implications for this study are to 1.) identify what makes a successful small business/business owner, 2.) address the types of obstacles faced by female small business owners, and 3.) what kind of resources could better assist this group. Therefore, the aim of this paper is to answer the following research questions: RQ1: According to Muted Group Theory, ‘language’ is a major barrier of entry for women ages 35 and older to be successful as entrepreneurs and resulting in being marginalized. What other obstacles do these women confront that also lead to this marginalization? RQ1b: Are there resources that are currently being utilized that assist in the progress of these women?

description: One of the main advantages of Logic Programming (LP) is that it provides an excellent framework for the parallel execution of programs. In this work we investigate novel techniques to efficiently exploit parallelism from real-world applications in low cost multi-core architectures. To achieve these goals, we revive and redesign the YapOr system to exploit or-parallelism based on a multi-threaded implementation. Our new approach takes full advantage of the state-of-the-art fast and optimized YAP Prolog engine and shares the underlying execution environment, scheduler and most of the data structures used to support YapOr's model. Initial experiments with our new approach consistently achieve almost linear speedups for most of the applications, proving itself as a good alternative for exploiting implicit parallelism in the currently available low cost multi-core architectures.

description: The paper discusses the geomorphology of the Sunda Trench, an oceanic trench located in the eastern Indian Ocean along the Sumatra and Java Islands of the Indonesian archipelago. It analysis difference in depths and variation in slope steepness between the two segments of the trench: southern Java transect (108.8°E 10.10°S - 113.0°E 10.75°S) and northern Sumatra transect (97.5°E 1.1°S - 101.0°E 5.5°S). The maps and geomorphological modelling were plotted using Generic Mapping Tools (GMT). The data include high-resolution grids on topography, geology, geodesy and geophysics: GEBCO, EGM2008 EGM-2008, GlobSed. The results include modelled segments, slope gradients, and cross-section profiles. The geological processes take place in the Indian Ocean at different stages of its evolution and influence the nature of the submarine geomorphology and geomorphology of the trench that differs in two segments. Java segment has a bell- shaped data distribution in contrast to the Sumatra with bimodal pattern. Java segment has the most repetitive depths at -2,500 to -5,200 m. Sumatra transect has two peaks: 1) a classic bell-shaped peak (-4,500 m to -5,500 m); 2) shelf area (0 to -1,750 m). The data at middle depths (-1,750 to -4,500 m) have less than 300 samples. The most frequent bathymetry for the Sumatra segment corresponds to the -4,750 m to -5,000 m. Comparing to the Sumatra segment, the Java segment is deeper. For depths > -6,000 m, there are only 138 samples for Sumatra while 547 samples for Java. Furthermore, Java segment has a more symmetrical geometric shape while Sumatra segment is asymmetric, one-sided. The Sumatra segment has a steepness of 57.86° on its eastern side (facing Sumatra Island) and a contrasting 14.58° on the western part. The Java segment has a steepness of 64.34° on its northern side (facing Java Island) and 24.95° on the southern part (facing the Indian Ocean). The paper contributes to the studies of the submarine geomorphology in Indonesia.
Fractionally charged topological point defects on the kagome lattice

description: We study a two-dimensional system of spin-polarized fermions on the kagome lattice at filling fraction f=1/3 interacting through a nearest-neighbor interaction V. Above a critical interaction strength V_c a charge-density wave with a broken Z_3 symmetry is stabilized. Using the unrestricted mean-field approximation, we present several arguments showing that elementary topological point defects in the order parameter bind a fractional charge. Our analysis makes use of two appealing properties of the model: (i) For weak interaction, the low-energy degrees of freedom are described by Dirac fermions coupled to a complex-valued mass field (order parameter). (ii) The nearest-neighbor interaction is geometrically frustrated at filling f=1/3. Both properties offer a route to fractionalization and yield a consistent value 1/2 for the fractional charge as long as the symmetry between the up and the down triangles of the kagome lattice is preserved. If this symmetry is violated, the value of the bound charge varies continuously with the strength of the symmetry-breaking term in the model. In addition, we have numerically computed the confining potential between two fractionally charged defects. We find that it grows linearly at large distances but can show a minimum at a finite separation for intermediate interactions. This indicates that the polaron state, formed upon doping the charge-density wave, can be viewed as a bound state of two defects.

We find that, in analogy to the Kerr-Newman-AdS Dirac Hamiltonian in $(1+3)$ dimensions, essential self-adjointness on $C_0^{\infty}(r_+,\infty)^2$ of the reduced (radial) Hamiltonian is implemented only if a suitable relation between the mass $μ$ of the Dirac field and the cosmological radius $l$ holds true. The very presence of a boundary-like behaviour of $r=\infty$ is at the root of this problem. Also, we determine in a complete way qualitative spectral properties for the non-extremal case, for which we can infer the absence of quantum bound states for the Dirac field. Next, we investigate the possibility of a quantum loss of angular momentum for the $(1 + 2)$-dimensional uncharged BTZ black hole. Unlike the corresponding stationary four-dimensional solutions, the formal treatment of the level crossing mechanism is much simpler. We find that, even in the extremal case, no level crossing takes place. Therefore, no quantum loss of angular momentum via particle pair production is allowed.

description: We study the magnetic properties of graphene edges and graphene/graphane interfaces under the influence of electrostatic gates. For this, an effective low-energy theory for the edge states, which is derived from the Hubbard model of the honeycomb lattice, is used. We first study the edge state model in a mean-field approximation for the Hubbard Hamiltonian and show that it reproduces the results of the extended 2D lattice theory. Quantum fluctuations around the mean-field theory of the effective one-dimensional model are treated by means of the bosonization technique in order to check the stability of the mean-field solution. We find that edge magnetism at graphene/graphane interfaces can be switched on and off by means of electrostatic gates. We describe a quantum phase transition between an ordinary and a ferromagnetic Luttinger liquid - a realization of itinerant one-dimensional ferromagnetism. This mechanism may provide means to experimentally discriminate between edge magnetism or disorder as the reason for a transport gap in very clean graphene nanoribbons.

description: We present simultaneous spatial and temporal polarization pulse shaping for two-photon excited fluorescence of dyes. A temporal pulse shaper and a subsequent spatial pulse shaper are used to generate laterally and axially tailored two-photon excited fluorescence profiles. The induced fluorescence is recorded for different polarization directions by utilizing the anisotropy of the dyes embedded in glycerol. We achieve an increased fluorescence contrast between different dyes by employing specific polarization shaped laser pulses and by taking polarization dependent emission into account. This versatile pulse shaping method is prospective for novel biophotonic imaging.

description: It is shown that the recently developed hybrid code VISHNU, which couples a relativistic viscous fluid dynamical description of the quark-gluon plasma (QGP) with a microscopic Boltzmann cascade for the late hadronic rescattering stage, yields an excellent description of charged and identified hadron spectra and elliptic flow measured in 200 A GeV Au+Au collisions at the Relativistic Heavy-Ion Collider (RHIC). Using initial conditions that incorporate event-by-event fluctuations in the initial shape and orientation of the collision fireball and values eta/s for the specific shear viscosity of the quark-gluon plasma that were recently extracted from the measured centrality dependence of the eccentricity-scaled, p_T-integrated charged hadron elliptic flow, we obtain universally good agreement between theory and experiment for the p_T-spectra and differential elliptic flow v_2(p_T) for both pions and protons at all collision centralities.

A Symbolic Approach to Generation and Analysis of Finite Difference Schemes of Partial Differential Equations

Year: 2010

description: In this paper we discuss three symbolic approaches for the generation of a finite difference scheme of a partial differential equation (PDE). We prove, that for a linear PDE with constant coefficients these three approaches are equivalent and discuss the applicability of them to nonlinear PDE's as well as to the case of variable coefficients. Moreover, we systematically use another symbolic technique, namely the cylindrical algebraic decomposition, in order to derive the conditions on the von Neumann stability of a difference s cheme for a linear PDE with constant coefficients. For stable schemes we demonst rate algorithmic and symbolic approach to handle both continuous and discrete di spersion. We present an implementation of tools for generation of schemes, which rely on Gröbner basis, in the system SINGULAR and present numerous e xamples, computed with our implementation. In the stability analysis, we use the system MATHEMATICA for cylindrical algebraic decomposition.

description: Рассмотрены особенности распространения углеводородных систем в осадочном чехле краевых Предуральского и Енисейско-Хатангского прогибов на территории Волго-Уральского нефтегазоносного и ЕнисейскоАнабарского газонефтеносного бассейнов. Выявлены черты сходства и различия. В обоих бассейнах высокие перспективы нефтегазоносности прогнозируются в глубокопогруженных палеозойских и допалеозойских (рифей-вендских) отложениях, предположительно в ловушках неструктурного типа. Детальная сводка о возрасте и числе продуктивных комплексов, типе и количестве содержащегося в них органического вещества (далее — ОВ), степени его катагенной преобразованности, количестве месторождений и фазовом состоянии добываемых флюидов, свойствах нефтей и газов этих прогибов является обобщением, дающим общую картину условий и среды нефтегазоносности, и базируется как на справочном материале [1–6], так и на личных разработках автора [7, 8].
description: The features of the distribution of hydrocarbon systems in the sedimentary cover in foredeep troughs Pre-Urals and Yenisei-Khatanga deflections on the territory of the Volga-Ural oil and gas and YeniseiAnabarsky gas-oil-bearing basins are considered. Some common and different features of the basins are described. In both basins, high oil and gas potential can be expected to realize in deeply submerged Paleozoic and pre-Paleozoic (RipheanVendian) sediments, presumably in nonstructural type traps.
A Generalised Methodology for the Investigation of Human Behavioural Responses to Hostile Attacks
Creators: name: Shipman, Alastair
Publisher: name: Imperial College London
Year: 2021

description: Terrorist attacks have become more frequent and more deadly in recent decades. Understanding the movement responses of the individuals involved can save lives. Pedestrian dynamics is an area of research and industry that investigates the movement of people. Using pedestrian dynamics to predict the responses to terrorist attacks could be hugely beneficial to the survival of those involved. This PhD developed a generalised methodology for investigating movement responses to terrorist attacks, accommodating the wide range of attack vectors seen in modern terrorism and providing a detailed summary of the data that should be obtained. Initial work analysed the overlap between pedestrian dynamics and terrorism. This concluded that current interdisciplinary research is not sufficiently advanced to allow for accurate predictions of pedestrian movement responses to terrorist attacks, due to a lack of usable data given the sensitivity of previous incidents and limitations on experimental methodologies. Two sets of experiments were then performed, examining responses to knife-based attacks by an unexpected and hostile individual. These experiments were split into physical reality (PR) and virtual reality (VR). The PR experiments were performed in December 2018 with 80 participants, and the VR experiments in January-February 2020 with 55 participants. The experiments obtained positional, physiological, psychological and memory-related measurements. Analysis of these datasets investigated the participant responses to hostile aggressors, including the impact of demographic, emotional state, and the similarity in responses between the VR and PR paradigms. The analysis on the psychological and physiological datasets proved a stressed response to the hostile individual, resulting in the first ever experimental dataset for these. The subsequent analysis on the positional and memory-related datasets provided key inputs for pedestrian dynamics models and concluded that VR is appropriate as a data-generating tool for human behaviour in emergencies.

description: We present the first measurement of the inclusive three-jet differential cross section as a function of the invariant mass of the three jets with the largest transverse momenta in an event in p anti-p collisions at sqrt(s) = 1.96 TeV. The measurement is made in different rapidity regions and for different jet transverse momentum requirements and is based on a data set corresponding to an integrated luminosity of 0.7 fb^{-1} collected with the D0 detector at the Fermilab Tevatron Collider. The results are used to test the three-jet matrix elements in perturbative QCD calculations at next-to-leading order in the strong coupling constant. The data allow discrimination between parametrizations of the parton distribution functions of the proton.

Structural and functional characterisation of the bacillus subtilis uridylyltransferase YngB

description: Nucleotide-activated sugars are key sugar donors for glycosylation processes in bacteria. In Bacillus subtilis strain 168, UDP-glucose is used for the decoration of the cell wall polymer wall teichoic acid (WTA) with glucose residues and for the production of membrane glucolipids. UDP-glucose is synthesised by UTP:glucose-1-phosphate uridylyltransferases (UGPases) from UTP and glucose-1-phosphate. In B. subtilis, the GtaB enzyme is essential for UDP-glucose production under standard aerobic growth conditions as WTA lacks glucose decoration and glucolipids are not produced in gtaB mutant strains. Interestingly, bioinformatic predictions indicate that additional UGPases are encoded in the B. subtilis genome including YngB, but the function of YngB has not been characterised to date. In this study, the crystal structure of YngB was solved and unveiled that YngB has the typical fold and all required features of a functional UGPase. Furthermore, using an in vitro enzyme assay it was shown that YngB has UGPase activity and uses UTP and glucose-1-phosphate as substrates. As for the function of YngB in B. subtilis, expression of YngB from an inducible synthetic promoter in a gtaB mutant resulted in glucose decoration on WTA and production of glucolipids, showing that YngB has UGPase activity in bacteria. Furthermore, as part of this study, the hypothesis that YngB is only expressed from its native promoter in B. subtilis under anaerobic conditions was investigated. This was done by growing wild-type and mutant strains of B. subtilis anaerobically. Indeed, YngB-dependent glucose decoration on WTA and glucolipids production could be detected in B. subtilis propagated under anaerobic growth conditions, showing that yngB is expressed from its native promoter under these growth conditions. Furthermore, based on the operon structure and regulation of yngB expression, it can be proposed that YngB potentially forms part of a multi-component glycosylation system functioning during anaerobic growth of B. subtilis. Lastly, in the final part of this study, preliminary data for the structural and functional characterisations of five different membrane-linked GT-A-fold glycosyltransferases involved in multi-component systems forming part of glycosylation pathways in bacteria are presented.
ALMA and the First Galaxies

description: ALMA will become fully operational in a few years and open a new window on primordial galaxies. The mm and submm domain is privileged, since the peak of dust emission between 60 and 100 microns is redshifted there for z= 5-10, and the continuum benefits from a negative K-correction. At least 100 times more sources than with present instruments could be discovered, so that more normal galaxies, with lower luminosities than huge starbursts and quasars will be surveyed. The high spatial resolution will suppress the confusion, which plagues today single dish bolometer surveys. Several CO lines detected in broad-band receivers will determine the redshift of objects too obscured to be seen in the optical. With the present instrumentation, only the most massive and gas rich objects have been detected in CO at high z, most of them being ultra-luminous starbursts with an extremely high star formation efficiency. However, selection biases are omni-present in this domain, and ALMA will statistically clarify the evolution of star formation efficiency, being fully complementary to JWST and ELTs.
