description: We propose a topology-aware distributed Reader-Writer lock that accelerates irregular workloads for supercomputers and data centers. The core idea behind the lock is a modular design that is an interplay of three distributed data structures: a counter of readers/writers in the critical section, a set of queues for ordering writers waiting for the lock, and a tree that binds all the queues and synchronizes writers with readers. Each structure is associated with a parameter for favoring either readers or writers, enabling adjustable performance that can be viewed as a point in a three dimensional parameter space. We also develop a distributed topology-aware MCS lock that is a building block of the above design and improves state-of-the-art MPI implementations. Both schemes use non-blocking Remote Memory Access (RMA) techniques for highest performance and scalability. We evaluate our schemes on a Cray XC30 and illustrate that they outperform state-of-the-art MPI-3 RMA locking protocols by 81% and 73%, respectively. Finally, we use them to accelerate a distributed hashtable that represents irregular workloads such as key-value stores or graph processing.

Στο έργο τριών, κυρίως, καλλιτέχνιδων που εκτέθηκε στο κοινό της εποχής, επισημαίνονται οι αισθητικές και τεχνοτροπικές αναφορές στο ευρωπαϊκό αυτό πνευματικό και καλλιτεχνικό ρεύμα, με σκοπό να αναδειχθεί η ιδιαιτερότητα του διαλόγου τους με αυτό. Η εξέταση της δημιουργίας τους, στη βάση του φεμινιστικού θεωρητικού λόγου για τους κατασκευασμένους κοινωνικούς ρόλους των φύλων, εξυπηρετεί την ανάδειξη άλλων παραμέτρων της, καθώς και ενός ιδιαίτερου υπόβαθρου προσέγγισης της εξπρεσιονιστικής τέχνης από τις Ελληνίδες δημιουργούς. Ακόμη, ο κριτικός λόγος που αναφέρθηκε στο έργο των καλλιτέχνιδων, χρησιμοποιείται για να συσχετισθεί η αρνητική υποδοχή του Εξπρεσιονισμού από το ελληνικό κοινό και η περιορισμένη παρουσία του στην ελληνική τέχνη του μεσοπολέμου με βασικές αισθητικές και ιδεολογικές συνιστώσες του πολιτισμικού και πολιτικού συνεχούς της εποχής. Στο τελευταίο μέρος της εργασίας, το έργο της τρίτης καλλιτέχνιδας παρέχει την αφετηρία, για μια σύντομη σκιαγράφηση των εκδοχών της ελληνικής εξπρεσιονιστικής τέχνης κατά την περίοδο του Β΄ Παγκοσμίου πολέμου, καθώς και των συνθηκών που συνέβαλαν στην ευρύτερη διάδοση της, σε αντίθεση με την προηγούμενη ιστορική περίοδο.
description: This dissertation is aiming to investigate the reception of Expressionism by women artists and intellectuals in Greece, in the years between the two World Wars. Αesthetic and stylistic references to this European intellectual and artistic movement, are marked mainly in the work of three female artists, which was exhibited to the public during this period, in order to particularize their dialogue with it. The examination of their work, on the basis of the feminist theory on genders, serves the manifestation of other parameters in it, as well as a special background in the Greek women artists’ approach to expressionist art. Furthermore, the critical discourse on artists’ work, is used to relate the negative reception of Expressionism by the greek public and its limited presence in the greek art of the period with the main aesthetic and ideological components of the cultural and political continuum. In the last part of the study, the artistic work of the third woman artist provides the starting point to outline briefly the versions of the greek expressionist art during the Second World War, as well as the conditions which contributed in its wider dissemination, in contrast with the precedent historical period.

description: Context. Extratidal stars are stellar bodies that end up outside the tidal radius of a cluster as a result of internal processes or external forces acting upon it. The presence and spatial distribution of these stars can give us insights into the past evolution of a cluster inside our Galaxy. Aims. Previous works suggest that globular clusters, when explored in detail, show evidence of extratidal stars. We aim to search for possible extratidal stars in the Galactic globular clusters NGC 6397, NGC 2808, and NGC 6266 using the photometry and proper motion measurements from Gaia DR2 database (Gaia Collaboration et al. 2018). Results. Finally, 120, 126, and 107 extratidal candidate stars were found lying outside the tidal radius of the globular clusters NGC 6397, NGC 2808, and NGC 6266, respectively. 70%, 25.4%, and 72.9% of the extratidal stars found are located outside the Jacobi radius of NGC 6397, NGC 2808, and NGC 6266, respectively. The spatial distribution of the extratidal stars belonging to NGC 6397 appears S-like, extending along the curved leading and trailing arms. NGC 2808 has an overdensity of stars in the trailing part of the cluster and NGC 6266 seems to have overdensities of extratidal stars in its eastern and northern sides. Conclusions. Proper motions and color-magnitude diagrams can be used to identify extratidal candidate stars around GCs. Nonetheless, depending on how different the kinematics and stellar populations of a cluster are compared to the Milky Way field, the fraction of contamination can be larger. All three clusters are found to have extratidal stars outside their tidal radii. For NGC 6397 and NGC 2808, these stars may be the result of a combined effect of the disc shocks and tidal disruptions. For NGC 6266, the distribution of extratidal stars is symmetrical around it, most likely indicating that the cluster has an extended stellar envelope.

description: Cilia and flagella have been carefully observed and described since the dawn of the microscopy era. However, their constituent proteins were not widely studied by cell biologists until the pivotal discovery that mammalian primary cilia are not “vestigial organelles,” as was once believed, but instead are crucial regulators of human health. As the field of ciliary biology has grown in the last two decades, there has been a simultaneous rapid expansion in the capabilities of functional proteomics. High-throughput proteomic techniques have provided key insights into the proteins that build and maintain cilia. In Chapter 1, I provide an overview of some of the most impactful insights gained from ciliary proteomic studies. In Chapter 2, I describe my work using a new high-throughput proteomic technique to systematically identify changes in cellular proteomic organization when a gene required for proper ciliary function is lost. Finally, in Chapter 3, I provide an overview of the main contributions of my work, which has provided new insights into ciliary biology while also further developing robust and broadly applicable proteomic tools.

Notre planète Terre est un système complexe dans lequel le vivant s’est développé aux interfaces entre les océans, les continents et l’atmosphère. La diversité de ces interfaces a permis l’implantation d’écosystèmes variés, composés de nombreuses espèces d’êtres vivants en relation entre elles, qui interagissent avec les milieux physiques en présence. Ces écosystèmes sont le siège de nombreux phénomènes physiques, chimiques et biologiques qui régulent les flux d’éléments chimiques, et des matières qui les contiennent, entre les différents compartiments de notre environnement. Par ailleurs, pratiquement tous les écosystèmes sont aujourd’hui anthropisés par le développement de l’humanité et de toutes les activités humaines. Ainsi, l’ensemble des cycles biogéochimiques sont modifiés, perturbés voire totalement transformés par les activités humaines. Il est intéressant de revenir sur les notions générales de chimie environnementale et sur les grandes lignes de quelques cycles déterminants, pour comprendre leur évolution possible sous la pression des activités humaines. En effet cette pression est croissante dans la période actuelle de la vie de notre Terre que l’on appelle de ce fait l’anthropocène.

description: Particle production and its effects on the inflaton field are investigated during the preheating phase of chaotic inflation using a model consisting of a massive scalar inflaton field coupled to N massless quantum scalar fields. The effects of spacetime curvature and interactions between the quantum fields are ignored. A large N expansion is used to obtain a coupled set of equations including a backreaction equation for the classical inflaton field. Previous studies of preheating using these equations have been done. Here the first numerical solutions to the full set of equations are obtained for various values of the coupling constant and the initial amplitude of the inflaton field. States are chosen so that initially the backreaction effects on the inflaton field are small and the mode equations for the quantum fields take the form of Mathieu equations. Potential problems relating to the parametric amplification of certain modes of the quantum fields are identified and resolved. A detailed study of the damping of the inflaton field is undertaken. Some predictions of previous studies are verified and some new results are obtained.

description: The purpose of this study was to evaluate the influence of a Greek traditional dance training program on the dynamic balance ability of individuals with MR. A total of 17 male and female individuals participated in the present study. Ten individuals (8 male, 2 female) with mild or moderate MR (mean age 18.1+2.0 yr, IQ 52-67) and seven individuals (6 male, 1 female) with mild or moderate MR (mean age 18.0+ 1.7yr, IQ 50-65) who studied in special school were assigned to intervention and control groups, respectively. The IQ of the individuals with MR was estimated by the Stanford-Binet Intelligence Scale. Pre- and post- training exercise tests were performed to determine the dynamic balance ability. Dynamic balance ability was measured by means of a balance deck (Lafayette) in 30, 45 and 60 sec intervals. The intervention group underwent a 16-wk exercise program at a frequency of 3 times per week and for a duration of 45 min per season. Post-training results showed that the individuals with MR on the intervention group improved during treatment, from their baseline scores on dynamic balance measurements (30sec: p

description: We investigate the relaxation dynamics of open non-integrable quantum many-body systems in the thermodynamic limit by using a tensor-network formalism. We simulate the Lindblad quantum master equation (LQME) of infinite systems by making use of the uniform matrix product operators (MPO) as the ansatz of their density matrices. Furthermore, we establish a method to measure the thermodynamic equivalence between two states described by the uniform MPOs. We numerically show that when an initial state of the LQME is a thermal Gibbs state, a time evolved state is always indistinguishable from a Gibbs state with a time-dependent effective temperature in the weak-dissipation and thermodynamic limit.

description: We introduce and study wheeled PROPs, an extension of the theory of PROPs which can treat traces and, in particular, solutions to the master equations which involve divergence operators. We construct a dg free wheeled PROP whose representations are in one-to-one correspondence with formal germs of SP-manifolds, key geometric objects in the theory of Batalin-Vilkovisky quantization. We also construct minimal wheeled resolutions of classical operads Com and Ass as rather non-obvious extensions of Com_infty and Ass_infty, involving, e.g., a mysterious mixture of associahedra with cyclohedra. Finally, we apply the above results to a computation of cohomology of a directed version of Kontsevich's complex of ribbon graphs.

description: Controlling non-equilibrium quantum dynamics in many-body systems is an outstanding challenge as interactions typically lead to thermalization and a chaotic spreading throughout Hilbert space. We experimentally investigate non-equilibrium dynamics following rapid quenches in a many-body system composed of 3 to 200 strongly interacting qubits in one and two spatial dimensions. Using a programmable quantum simulator based on Rydberg atom arrays, we probe coherent revivals corresponding to quantum many-body scars. Remarkably, we discover that scar revivals can be stabilized by periodic driving, which generates a robust subharmonic response akin to discrete time-crystalline order. We map Hilbert space dynamics, geometry dependence, phase diagrams, and system-size dependence of this emergent phenomenon, demonstrating novel ways to steer entanglement dynamics in many-body systems and enabling potential applications in quantum information science.

description: We discuss recent results of the replica approach to statistical mechanics of a single classical particle placed in a random N(>>1)-dimensional Gaussian landscape. The particular attention is paid to the case of landscapes with logarithmically growing correlations and to its recent generalisations. Those landscapes give rise to a rich multifractal spatial structure of the associated Boltzmann-Gibbs measure. We also briefly mention related results on counting stationary points of random Gaussian surfaces, as well as ongoing research on statistical mechanics in a random landscape constructed locally by adding many squared Gaussian-distributed terms.

description: Understanding nonequilibrium systems and the consequences of irreversibility for the system's behavior as compared to the equilibrium case, is a fundamental question in statistical physics. Here, we investigate two types of nonequilbrium phase transitions, a second-order and an infinite-order phase transition, in a prototypical q-state vector Potts model which is driven out of equilibrium by coupling the spins to heat baths at two different temperatures. We discuss the behavior of the quantities that are typically considered in the vicinity of (equilibrium) phase transitions, like the specific heat, and moreover investigate the behavior of the entropy production (EP), which directly quantifies the irreversibility of the process. For the second-order phase transition, we show that the universality class remains the same as in equilibrium. Further, the derivative of the EP rate with respect to the temperature diverges with a power-law at the critical point, but displays a non-universal critical exponent, which depends on the temperature difference, i.e., the strength of the driving. For the infinite-order transition, the derivative of the EP exhibits a maximum in the disordered phase, similar to the specific heat. However, in contrast to the specific heat, whose maximum is independent of the strength of the driving, the maximum of the derivative of the EP grows with increasing temperature difference. We also consider entropy fluctuations and find that their skewness increases with the driving strength, in both cases, in the vicinity of the second-order transition, as well as around the infinite-order transition.

description: We have introduced a novel Majorana representation of S=1/2 spins using the Jordan-Wigner transformation and have shown that a generalized spin model of Kitaev defined on a brick-wall lattice is equivalent to a model of non-interacting Majorana fermions with Z_2 gauge fields without redundant degrees of freedom. The quantum phase transitions of the system at zero temperature are found to be of topological type and can be characterized by nonlocal string order parameters. In appropriate dual representations, these string order parameters become local order parameters and the basic concept of Landau theory of continuous phase transition can be applied.

description: This scientific research was based on the articles of the newspaper “ Kathimerini” referring to the subject ‘Lone parent households’ that were published in 2004,2005,2006.All the articles were collected from the electronic demonstration of the newspaper and its electronic records, through the internet by using key words. This specific newspaper was chosen because of its deep interest in social matters and its wide circulation. The main goal of this research was to examine if there were any references on the matters of Lone parent households’, the problems or difficulties that were demonstrated as important and the frequency they were published. It was examined whether the journalistic team was influenced by the announcement of the EU survey results about poverty and social isolation. Moreover, it was examined, if the journalistic demonstration has marked out the real problems, in order to influence in a positive way the public opinion, about this matter.
The formation of glycolonitrile (HOCH$_2$CN) from reactions of C$^+$ with HCN and HNC on icy grain mantles

description: Quantum chemical cluster calculations show that reactions of C$^+$ with HCN or HNC embedded in the surface of an icy grain mantle can account for the formation of a recently detected molecule, glycolonitrile, which is considered to be an important precursor to ribonucleic compounds. Reactions of cations deposited on ice mantles with minimal kinetic energy have been found theoretically to result in previously unknown pathways to significant organic compounds in protostellar systems and the interstellar medium. In density functional theory cluster calculations involving up to 24H$_2$O, C$^+$ reacts consistently with HCN embedded in ice to yield the neutral HOCHNC radical with no barrier, along with H$_3$O+ as a byproduct. If HOCHNC then reacts with H, three species can be formed: HOCH$_2$CN (isocyanomethanol), HOCH$_2$CN (glycolonitrile), and HOCHNCH. For the C$^+$ + HNC reaction on ice, the HOCHCN and H$_2$OCCN radicals form as intermediates, the first of which is another direct precursor to glycolonitrile via H addition. In addition to characterizing reaction pathways, predictions are provided of the vibrational and electronic spectra of the HCN and HNC starting clusters and the HOCHNC ice-bound intermediate.

Making sense of teacher collaboration : a case study of two teachers’ engagement in clinical supervision
Creators: name: Langmuir, David Allan
Publisher: name: University of British Columbia
Year: 2009

description: The study addresses the process of teacher development in the context of close collegial relations. It is a case study of two teachers, Mary and Sadie, who worked collaboratively over two school years in a series of reciprocal cycles of clinical supervision. The main purposes the teachers held for the process were to develop their understanding about their teaching practices in order to grow professionally and to acquire new skills in supervision. Their beliefs, behaviours, and knowledge contributed to shape their relationship and serve their respective needs for growth. An interpretive methodology was employed. The research approach was derived from the theoretical perspective of George Herbert Mead (1932, 1934, 1938). This provided for an analytical description and interpretation of the meanings and knowledge constructed socially by the participating teachers about clinical supervision, collegiality and teacher development. It also enabled the identification of a number of factors which influenced the teachers' development in the context of a collegial relationship. The teachers practiced new behaviours in an unfamiliar context of close colleagueship in order to incorporate research-based knowledge into their practical working lives. They devoted considerable effort and attention during the first year to the mechanics of clinical supervision in order to become more proficient with the process. In the second year of the study, the teachers explicitly rejected the term "clinical supervision" in favour of "reflective conferencing". The new terminology reflected their deeper understanding about the processes of collaboration and reflection. As their relationship, knowledge and skills developed, they became more thoughtful about collaboration and purposeful about facilitating each other's development. The teachers discovered that change takes time and occurs incrementally. Trust was required from both colleagues, in the process and in each other, as they took turns observing each other teach and then meeting to discuss matters related to their instructional practice. A culture of collaboration took hold, albeit more slowly than either had envisioned. Through repeated practice in reflective conferencing, they acquired an appreciation of the challenges and benefits of collaboration for the promotion of teacher development.

description: To understand the phase transition phenomena, information theoretical approaches can pick up some important properties of the phenomena based on the probability distribution. In this paper, we show information theoretical aspects of the 3-dimensional 3-state Potts model with the external field which is corresponding to the QCD effective model with heavy quarks. The transfer mutual information which represents the information flow of two spin variables is numerically estimated based on the Markov-chain Monte-Carlo method. The transfer mutual information has the peak near the confinement-deconfinement transition, and it may be used to detect the precursors of the transition. Since the transfer mutual information still have the peak even if the Polyakov-loop changes continuously and smoothly, we may pick up some aspects of the confinement-deconfinement nature from the information flow properties. Particularly, the transfer mutual information shows the significantly different behavior below and above the Roberge-Weiss endpoint existed in the pure imaginary chemical potential region, which may indicate the system change by the confinement-deconfinement transition.

First-passage time theory of activated rate chemical processes in electronic molecular junctions

description: Confined nanoscale spaces, electric fields and tunneling currents make the molecular electronic junction an experimental device for the discovery of new, out-of-equilibrium chemical reactions. Reaction-rate theory for current-activated chemical reactions is developed by combining a Keldysh nonequilibrium Green's functions treatment of electrons, Fokker-Planck description of the reaction coordinate, and Kramers' first-passage time calculations. The NEGF provide an adiabatic potential as well as a diffusion coefficient and temperature with local dependence on the reaction coordinate. Van Kampen's Fokker-Planck equation, which describes a Brownian particle moving in an external potential in an inhomogeneous medium with a position-dependent friction and diffusion coefficient, is used to obtain an analytic expression for the first-passage time. The theory is applied to several transport scenarios: a molecular junction with a single, reaction coordinate dependent molecular orbital, and a model diatomic molecular junction. We demonstrate the natural emergence of Landauer's blowtorch effect as a result of the interplay between the configuration dependent viscosity and diffusion coefficients. The resultant localized heating in conjunction with the bond-deformation due to current-induced forces are shown to be the determining factors when considering chemical reaction rates; each of which result from highly tunable parameters within the system.
Electronic Structure of Copper Phthalocyanine: a Comparative Density Functional Theory Study

description: We present a systematic density functional theory study of the electronic structure of copper phthalocyanine (CuPc), using several different (semi)-local and hybrid functionals, and compare the results to experimental photoemission data. We show that semi-local functionals fail qualitatively for CuPc, primarily because of under-binding of localized orbitals due to self-interaction errors. We discuss an appropriate choice of functional for studies of CuPc/metal interfaces and suggest the Heyd-Scuseria-Ernzerhof screened hybrid functional as a suitable compromise functional.

description: The micro/nano-structural evolution before and after tensile/compressive loading, fatigue and ultimately, failure has been studied by Raman (and IR) microspectroscopy for PBO, PET, PA66, PP, silk and hair using three probes: low wavenumber collective modes at <150cm-1 as representative of the crystalline/ordered and amorphous chains, stretching and bending modes, as representative of the C-C/ C-N polymeric backbone, and localized vibrations (OH, NH) to probe the inter-macromolecule segment distance. Wavenumber and bandwidth distribution across fibre diameters reveal different types of skin/core heterogeneity. The in situ analysis at different strain/pressure levels shows that amorphous chains in the fibre accommodate the stress differently. The post mortem analysis shows that amorphous domains can be higly stressed during the failure and remnant stress can be measured.

Από την ανάλυση των αποτελεσμάτων φαίνεται ότι οι πλείστοι εκπαιδευτικοί δεν έχουν διαμορφωμένη άποψη σε αρκετές ερωτήσεις που αφορούν τρόπους διαχείρισης των δίγλωσσων μαθητών. Ενώ από τη μία θεωρούν την παρουσία τους στο σχολικό χώρο και την τάξη θετική τόσο για τους ίδιους όσο και για το σύνολο του μαθητικού πληθυσμού, εντούτοις η παρουσία της συγκεκριμένης ομάδας παιδιών αποτελεί εμπόδιο για τη διαδασκαλία, κυρίως λόγω της περιορισμένης τους γνώσης στην ελληνική γλώσσα
description: The aim of this assignment is to put down teacher's point of view with the presentation and the performance of the students in the elementary educational grade and having greek as second language. The analysis of the results proofs that most of the teachers do not have a formulated opinion in various questions concerning ways to handle bilingual students. Also, even though the presence of these students in the class is considered positive for themselves, as well as for the rest of the students, on the other hand the presence of this specific group of students creates an obstacle during lessons, mainly due to their limited knowledge of the greek language
