description: Η διπλωματική εργασία εκπονείται στα πλαίσια του μαθήματος των Διεθνών Σχέσεων και έχει ως αντικείμενο μελέτης τη σχέση που αναπτύσσεται τα τελευταία χρόνια ανάμεσα στη διπλωματία και τα μέσα κοινωνικής δικτύωσης. Ως ένα εργαλείο για τη χάραξη και την άσκηση της εξωτερικής πολιτικής ενός κράτους, η διπλωματία ασκείται σε ένα διεθνές πολιτικό περιβάλλον, στους δρώντες του οποίου περιλαμβάνονται κράτη, διεθνείς διακυβερνητικοί οργανισμοί και μη κρατικοί παράγοντες, και του οποίου η δομή και η λειτουργία υφίσταται τις επιρροές της παγκοσμιοποίησης και των φαινομένων της, και εν προκειμένω εκείνο των τεχνολογικών επαναστάσεων. Μέρος των τελευταίων συνιστούν οι τεχνολογίες επικοινωνίας και πληροφόρησης, με το διαδίκτυο και τα μέσα κοινωνικής δικτύωσης να διακρίνονται για την συνεχώς εκτεταμένη ανάπτυξη και αυξανόμενη δημοτικότητα και να χρησιμοποιούνται ως εργαλείο άσκησης διπλωματίας για τους κυβερνητικούς και διπλωματικούς εταίρους. Το κεντρικό ερώτημα συνίσταται στο, αν και σε ποιο βαθμό η διπλωματία έχει προσλάβει μια νέα μορφή, τέτοια ώστε να μπορούμε να ισχυριστούμε ότι πλέον υπεκφεύγει του κρατοκεντρικού πλαισίου άσκησής της.
description: The master’s thesis is prepared in the framework of the postgraduate course of International Relations, and its subject consists in the study of the current development of the relationship between diplomacy and social media. As a tool for the mapping out and the conduct of a state’s foreign policy, diplomacy is performed in an international political environment whose actors include states, international governmental organizations and non-state actors, and whose structure and function undergo the influences of globalization and its dimensions, as the case of technological revolutions at issue. Parts of the latter constitute the information and communication technologies (ICTs), with the Internet and the social media to constantly stand out for their extensive growth and increasing popularity and to be used as a tool of diplomacy for governmental and diplomatic partners. The key question consists in, whether and to what extent the diplomacy has taken on a new form, such that we can no longer protest its state-centric framework of exercise.

description: We report on a study of the dynamics of decoherence of a matter-wave interferometer, consisting of a pair of low-dimensional cold atom condensates at finite temperature. We identify two distinct regimes in the time dependence of the coherence factor of the interferometer: quantum and classical. Explicit analytical results are obtained in both regimes. In particular, in the two-dimensional (2D) case in the classical (long time) regime, we find that the dynamics of decoherence is universal, exhibiting a power-law decay with an exponent, proportional to the ratio of the temperature to the Kosterlitz-Thouless temperature of a single 2D condensate. In the one-dimensional (1D) case in the classical regime we find a universal nonanalytic time dependence of decoherence, which is a consequence of the nonhydrodynamic nature of damping in 1D liquids.

description: Bibliographical studying about various subjects on .special education in¬cludes many questions about the practical dimensions of learning disabili¬ties, like '"which characteristics can ensure specialists that some kids have to be students in a class which provides special education. Questions like these consist the basis of this research. The research started in March 2001 and was completed in May 2001. One hundred and sixty (160) participants were chosen from Primary Education in Central Macedonia, Northern Greece. Half of the boys and girls who participated in the research appeared as students with learning disabilities and the test of them appeared as ordi¬nary students. For the comparison between them "Athena Test" was used. This particular test examines student's progress in five academic areas: in¬telligence, memory of retinues, completion of representations; graphical phonological awareness and neuron-psychological ripening. The questions of the research were: a) are there any differences between students with learn¬ing disabilities and those without learning disabilities in general categories in "Athena Test"? b) are there any differences between these two groups in terms of quality variables?, c) are there any differences between boys and girls?. The results showed noteworthy differences between these two groups in all categories, except "Writing distinction". Differences between boys and girls were noticed as well.

description: The radiative corrections of the strong and electroweak interactions are calculated for the Higgs-boson decays H -> WW/ZZ -> 4f with semileptonic or hadronic four-fermion final states in next-to-leading order. This calculation is improved by higher-order corrections originating from heavy-Higgs-boson effects and photonic final-state radiation off charged leptons. The W- and Z-boson resonances are treated within the complex-mass scheme, i.e. without any resonance expansion or on-shell approximation. The calculation essentially follows our previous study of purely leptonic final states. The electroweak corrections are similar for all four-fermion final states; for integrated quantities they amount to some per cent and increase with growing Higgs-boson mass M_H, reaching 7-8% at M_H \sim 500 GeV. For distributions, the corrections are somewhat larger and, in general, distort the shapes. Among the QCD corrections, which include corrections to interference contributions of the Born diagrams, only the corrections to the squared Born diagrams turn out to be relevant. These contributions can be attributed to the gauge-boson decays, i.e. they approximately amount to α_s/πfor semileptonic final states and 2α_s/πfor hadronic final states. The discussed corrections have been implemented in the Monte Carlo event generator PROPHECY4F.

description: We study three wave function optimization methods based on energy minimization in a variational Monte Carlo framework: the Newton, linear and perturbative methods. In the Newton method, the parameter variations are calculated from the energy gradient and Hessian, using a reduced variance statistical estimator for the latter. In the linear method, the parameter variations are found by diagonalizing a non-symmetric estimator of the Hamiltonian matrix in the space spanned by the wave function and its derivatives with respect to the parameters, making use of a strong zero-variance principle. In the less computationally expensive perturbative method, the parameter variations are calculated by approximately solving the generalized eigenvalue equation of the linear method by a nonorthogonal perturbation theory. These general methods are illustrated here by the optimization of wave functions consisting of a Jastrow factor multiplied by an expansion in configuration state functions (CSFs) for the C$_2$ molecule, including both valence and core electrons in the calculation. The Newton and linear methods are very efficient for the optimization of the Jastrow, CSF and orbital parameters. The perturbative method is a good alternative for the optimization of just the CSF and orbital parameters. Although the optimization is performed at the variational Monte Carlo level, we observe for the C$_2$ molecule studied here, and for other systems we have studied, that as more parameters in the trial wave functions are optimized, the diffusion Monte Carlo total energy improves monotonically, implying that the nodal hypersurface also improves monotonically.

description: In the present paper, we consider a class of two players infinite horizon differential games, with piecewise smooth costs exponentially discounted in time. Through the analysis of the value functions, we study in which cases it is possible to establish the existence Nash equilibrium solutions in feedback form. We also provide examples of piecewise linear costs whose corresponding games have either infinitely many Nash equilibria or no solutions at all.

description: We use nucleon-nucleon phase shifts obtained from experimental data, together with the chiral expansion for the long-distance part of the NN interaction, to obtain information about the short-distance piece of the NN potential that is at work in the 1S0 channel. We find that if the scale R that defines the separation between "long-" and "short-" distance is chosen to be \lsim 1.8 fm then the energy dependence produced by short-distance dynamics is well approximated by a two-term polynomial for Tlab < 200 MeV. We also find that a quantitative description of NN dynamics is possible, at least in this channel, if one treats the long-distance parts of the chiral NN potential in perturbation theory. However, in order to achieve this we have to choose a separation scale R that is larger than 1.0 fm.

description: We propose that the Universe is filled with a massive vector field, non-minimally coupled to gravitation. The field equations of the model are consistently derived and their application to cosmology is considered. The Friedmann equations acquire an extra dark-energy component, which is proportional to the mass of the vector particle. This leads to a late-time accelerated de Sitter type expansion. The free parameters of the model (gravitational coupling constants and initial value of the cosmological vector field) can be estimated by using the PPN solar system constraints. The mass of the cosmological massive vector particle, which may represent the main component of the Universe, is of the order of 10^-63 g.

Model for unidirectional movement of axonemal and cytoplasmic dynein molecules

description: A model for the unidirectional movement of dynein is presented based on structural observations and biochemical experimental results available. In this model, the binding affinity of dynein for microtubule is independent of its nucleotide state and the change between strong and weak microtubule-binding is determined naturally by the variation of relative orientation between the stalk and microtubule as the stalk rotates following nucleotide-state transition. Thus the enigmatic communication from the ATP binding site in the globular domain to the far MT-binding site in the tip of the stalk, which is prerequisite in conventional models, is not required. Using the present model, the previous experimental results such as the effect of ATP and ADP bindings on dissociation of dynein from microtubule, the processive movement of single-headed axonemal dyneins at saturating ATP concentration, the load dependence of step size for the processive movement of two-headed cytoplasmic dyneins and the dependence of stall force on ATP concentration can be well explained.

description: The article deals with the words that occur in the texts by the Silver Age poet Mikhail Kuzmin no more than once. It has to be said that the problem of describing units in the author's lexicography is connected, in particular, with the selection of key words in the poetic language. There is no direct correspondence between the frequency of occurrence in the text and the significance of the word in the poetic picture of the world. The analysis of unique words should help to place grammatical, stylistic, semantic and word-formation accents in identifying the keywords of an individual author.

description: Parents' involvement has been described as essential for the effectiveness of any mainstreaming process. This research attempts to investigate the functioning of inclusive classes from parents' point of view. Forty-seven mothers of children attending such classes were interviewed, in order to explore how their children were treated and how they themselves were involved. The findings suggest that although mothers make a positive evaluation of the educational contest of mainstreaming, the inclusive provisions do not seem to meet the overall needs of the child and of the family. Professionals-parents partnership is not fulfilled and the interdisciplinary approach stays incomplete.

description: We report on the discovery and analysis of the transient X-ray pulsar CXO/XMMU J073709.13+653544 detected in the 2004 August-October Chandra and XMM observations of the nearby spiral galaxy NGC2403. The source exhibits X-ray pulsations with a period P~18 s, a nearly sinusoidal pulse shape and pulsed fraction 46-70%. The source shows a rapid decrease of the pulsation period from 18.25 s on Aug. 9 to 17.93 s on Sep. 12 and possibly 17.56 s on Oct. 3, 2004. The X-ray spectra of the source are hard and are well fitted with an absorbed simple power law of photon index 0.9~1.2. The X-ray properties of the source and the absence of an optical/UV counterpart allow us to identify CXO/XMMU J073709.13+653544 as accreting X-ray pulsar in NGC2403. The maximum unabsorbed luminosity of the source in the 0.3-7 keV range, ~2.6x10e38 erg/s at 3.2 Mpc, is at least 260 times higher than its quiescent luminosity. The corresponding luminosity in the 0.3-100 keV energy range could be as high as ~1.2x10e39 erg/s, assuming the typical pulsar energy spectrum with high-energy cut-off at 10-20 keV. The rate of decrease of the pulsation period of the source (-10e-7 s/s) is one of the fastest observed among accreting pulsars. The evolution of the pulsation period suggests that it is dominated by the intrinsic spin-up of the compact object. The accretion rate implied by X-ray luminosity of CXO/XMMU J073709.13+653544 could account for the observed spin-up rate, assuming that the X-ray source is powered by disk accretion onto highly magnetized neutron star. Based on the transient behavior and overall X-ray properties of the source, we conclude that it could be an X-ray pulsar belonging to either a Be binary system or a low-mass system similar to GRO J1744-28.

description: Cooperative learning is considered to be an effective method for the development of children. Additionally, language teaching is widely based on the communicative approach, which was recently introduced by the Greek authorities. The combination of the two methods was examined on theoretical and practical level. Theoretically, it was found that the principles of cooperative learning support communicative -approaches. Both methods facilitate dynamic learning and acknowledge the cognitive, emotional and social needs of students. The interplay of the methods proved to be an effective tool in learning and leaching. In practice, organizing and experimentally implementing two thematic units in a 5th grade class in Nicosia, Cyprus tested the effects of cooperative Seaming and the communicative approach. Data analysis showed that the experimental group was more capable of interpreting the social situation, in which communication was taking place, and responding accordingly. Most importantly, increased responsibilities motivated children to develop meta-cognitive abilities and commit themselves towards their team and the class.

description: We investigated the preservation of information encoded into the relative phase and amplitudes of optical pulses during storage and retrieval in an optical memory based on stimulated photon echo. By interfering photon echoes produced in a Ti-indiffused single-mode Er-doped LiNbO$_{3}$ waveguiding structure at telecom wavelength, we found that decoherence in the atomic medium translates only as losses (and not as degradation) of information, as long as the data pulse series is short compared to the atomic decoherence time. The experimentally measured value of the visibility for interfering echoes is close to 100 %. In addition to the expected three-pulse photon-echo interferences we also observed interference due to a four-pulse photon echo. Our findings are of particular interest for future long-distance quantum communication protocols, which rely on the reversible transfer of quantum states between light and atoms with high fidelity.

Observations were performed with the Long Wavelength Spectrometer (LWS) Fabry-Perots on board the Infrared Space Observatory (ISO). In total, more than 20 resolved OH rotational lines, with upper energy levels up to 620 K, have been detected at an angular and velocity resolutions of 80$'' and 33 km s^-1 respectively. OH line profiles show a complex behavior evolving from pure absorption, P-Cygni type to pure emission. We also present a large scale 6' declination raster in the OH ^2Π_3/2 J=5/2^+-3/2^- and ^2Π_3/2 J=7/2^-5/2^+ lines (at 119.441 and 84.597 um) revealing the decrease of excitation outside the core of the cloud. From the observed profiles, mean intrinsic line widths and velocity offsets between emission and absorption line peaks we conclude that most of the excited OH arises from Orion outflow(s), i.e. the ``plateau'' component. We determine an averaged OH abundance relative to H_2 of X(OH)=(0.5-1.0)x10^-6, a kinetic temperature of 100 K and a density of n(H_2)=5x10^5 cm^-3. Even with these conditions, the OH excitation is heavily coupled with the strong dust continuum emission from the inner hot core regions and from the expanding flow itself.

description: The objective of this project is to study a specific problem of real-time task Scheduling. We develop a Scheduling algorithm for non-preemptive soft real time tasks on multiprocessors using multiobjective genetic algorithms. The objective of the algorithm is to minimize the total tardiness and the total number of processors. It is assumed that the tasks have precedence relations among them and are executing on homogeneous multiprocessor environment. A third objective function added to the problem in order to minimize the total idle time simultaneously.
Use of peptide fragments for investigating calcium-binding proteins and protein folding

description: Two projects are described that use synthetic peptides to study protein structure. The EF-hand Ca²⁺ binding protein calbindin D[sub 9k] was studied by synthesizing and characterizing peptides corresponding to each Ca²⁺ binding domain. The peptide called calb 1 corresponds to the site I binding domain and the peptide called calb 2 corresponds to site II. Circular dichroism (CD) spectra in collaboration with ΔV and calorimetry experiments determined by other groups indicated that calb 1 alone does not bind Ca²⁺. Calb 2 binds Ca²⁺ in a mechanism whereby one Ca²⁺ enables two peptides to be folded into a helical conformation in an apparent dimer. A 1:1 mixture of calb 1 and calb 2, called calb 1/2, binds two equivalents of Ca²⁺ into a helical conformation in an apparent heterodimer. The mechanism appears to be stepwise in which calb 2 binds the first Ca²⁺ and calb 1 binds the second Ca²⁺. This indicates a positive cooperative effect conferred by calb 2 onto calb 1. Our results are consistent with previous work on the intact calbindin D[sub 9k] indicating a strong dependence on favourable electrostatic interactions between Ca²⁺ and side chain ligands for high binding affinity, and positive cooperativity between the two binding domains. CD experiments of calb 2 and calb 1/2 in the presence of 0.1 M KC1 showed a smaller increase in helical content upon Ca²⁺ addition when compared to the absence of salt. The results in the presence of 0.1 M KCl corroborate the importance of electrostatic interactions in the Ca²⁺ binding affinity of the peptides. A peptide called aac-heme, which corresponds to helices F and G (residues 80 to 108) of the ά-chain of horse methemoglobin, was synthesized and characterized by CD spectroscopy. The sequence of aac-heme adopts a structure, called an ά,ά-corner in the intact protein, which has been hypothesized to be a protein folding initiator (Efimov, A. V . (1984) FEBS Lett. 166, 33-38). We tested Efimov's hypothesis by analysing the CD spectra of aac-heme in aqueous buffer and trifluoroethanol (TFE) solutions. Aac-heme is moderately helical in aqueous buffer and this helicity is concentration dependent. This indicates that aac-heme aggregates to compensate for the lack of tertiary interactions which would otherwise be present in the intact protein. Aac-heme is fully helical in 60% TFE solution suggesting that a hydrophobic environment enhances the helicity of this peptide. These observations are consistent with a folding mechanism for the native hemoglobin whereby a hydrophobic collapse occurs first, followed by the formation of secondary structure. The results suggest that the ά,ά-corner could well initiate the secondary structural formation in hemoglobin and that this initiation would be even more pronounced if it was preceded by a hydrophobic collapse of the unfolded hemoglobin. Thus, the ά,ά-corner may be integral in the folding pathway, as Efimov proposed.

description: Classification using high-dimensional features arises frequently in many contemporary statistical studies such as tumor classification using microarray or other high-throughput data. The impact of dimensionality on classifications is poorly understood. In a seminal paper, Bickel and Levina [Bernoulli 10 (2004) 989--1010] show that the Fisher discriminant performs poorly due to diverging spectra and they propose to use the independence rule to overcome the problem. We first demonstrate that even for the independence classification rule, classification using all the features can be as poor as the random guessing due to noise accumulation in estimating population centroids in high-dimensional feature space. In fact, we demonstrate further that almost all linear discriminants can perform as poorly as the random guessing. Thus, it is important to select a subset of important features for high-dimensional classification, resulting in Features Annealed Independence Rules (FAIR). The conditions under which all the important features can be selected by the two-sample $t$-statistic are established. The choice of the optimal number of features, or equivalently, the threshold value of the test statistics are proposed based on an upper bound of the classification error. Simulation studies and real data analysis support our theoretical results and demonstrate convincingly the advantage of our new classification procedure.

description: Visual poetry in Russian culture, however, as well as in the world, has gone through an accelerated path of development. At the beginning of the 19th century, "visual poetry" as a separate art direction did not yet exist. At the beginning of the 21st century, visual poetry turned from a sacred-closed phenomenon into a living breeding ground for profane advertising texts, all kinds of comics and entered the streets in the form of graffiti. However, the creative laboratory of visual poetry does not cease to gush, as in the work of one of the founders of this type of poetry - G. Apollinaire. The article deals with the history and theory of visual poetry in Russia.

description: Στόχος της παρούσας εργασίας είναι να επιλύσουμε την μονοδιάστατη εξίσωση του Schrödinger παρουσία μιας έξτρα συμπαγούς διάστασης. Χρησιμοποιώντας ένα τροποποιημένο διδιάστατο δυναμικό κβαντικού αρμονικού ταλαντωτή, εφαρμόζουμε κατάλληλα μαθηματικά εργαλεία για να εξάγουμε τα επιθυμητά αποτελέσματα. Για το σκοπό αυτό, η μέθοδος του αναπτύγματος του Magnus χρησιμοποιείται ως προσέγγιση της λύσης του προβλήματος, με σκοπό να παρέχει μια σύγκριση με την λύση που προκύπτει με αριθμητική ολοκλήρωση. Το θεώρημα του Floquet χρησιμοποιείται καθώς παρέχει τις λύσεις που προκύπτουν από σύστημα γραμμικών διαφορικών εξισώσεων με περιοδικούς συντελεστές. Εφαρμόζουμε το θεώρημα αυτό στην Δ.Ε. του Mathieu, η οποία εντάσσεται στις Δ.Ε. Hill. Για να προχωρήσουμε στην επίλυση του Schrödinger προβλήματος, θεωρούμε ότι η λύση μπορεί να γραφεί ως ανάπτυγμα σε σειρά συναρτήσεων, με χρήση ως βάση τις ιδιοσυναρτήσεις του κβαντικού αρμονικού ταλαντωτή, όπου η έξτρα διάσταση είναι κρυμμένη στους συντελεστές του αναπτύγματος. Με αυτόν τον τρόπο, το πρόβλημα ανάγεται τελικά σε ένα πινακικό πρόβλημα διαφορικών εξισώσεων.
description: Our goal in this project is to solve the one dimensional Schrödinger equation in the presence of one extra compact dimension. By using a modified 2-dimensional quantum harmonic oscillator potential, we apply appropriate mathematical tools to establish results that will shed light into the desired direction. To this end, Magnus’ expansion method is used as an approximation tool, in order to provide a comparison with the solution derived from numerical integration. The Floquet theorem is implemented as it provides the solutions that are found in a system of differential equations with periodic coefficients. We apply this theorem in the Mathieu differential equation, a Hill's differential equation problem. In order to proceed with the Schrödinger problem, we assume that the solution can be written as a functional series in terms of the harmonic oscillator eigenfunctions, where the extra dimension dependence is hidden into the expansion coefficients. This way our problem becomes a matrix differential equation problem.
