description: Ο Ευθύμιος Μαλάκης έζησε και έδρασε κατά τον 12ο αιώνα. Το συγγραφικό του έργο απαρτίζεται από έξι λόγους, τρία εγκώμια με αποδέκτη τον αυτοκράτορα Μανουήλ Α΄ Κομνηνό, δύο μονωδίες για τον Αλέξιο Κομνηνό Κοντοστέφανο και τον Ευστάθιο Θεσσαλονίκης και έναν επιτάφιο για τον μητροπολίτη Αθηνών Νικόλαο Αγιοθεοδωρίτη, ένα επίγραμμα και τριάντα πέντε επιστολές. Αντικείμενο της παρούσας εργασίας αποτελεί η μελέτη της συλλογής των επιστολών του. Στο πρώτο μέρος της εργασίας εξετάζεται λεπτομερώς ο βίος του συγγραφέα και το έργο του ως μητροπολίτη Νέων Πατρών, ενώ επιχειρείται και μια συνοπτική μελέτη των λόγων του και της χειρόγραφης παράδοσής τους. Στο δεύτερο μέρος παρουσιάζεται αναλυτικά το περιεχόμενο των τριανταπέντε επιστολών του. Σε όσες περιπτώσεις υπάρχουν επαρκή στοιχεία γίνεται προσπάθεια να χρονολογηθούν ορισμένες από αυτές ή να ταυτιστούν οι αποδέκτες τους. Παράλληλα παρατίθενται τα προσωπογραφικά στοιχεία των αλληλογράφων του Μαλάκη. Στο τρίτο και τελευταίο τμήμα της εργασίας μελετάται η δομή και η γλώσσα των επιστολών του συγγραφέα. Αρχικά, αναλύεται η δομή των επιστολών και στη συνέχεια τα μοτίβα και τα παραθέματα που απαντούν σε αυτές. Τέλος, η μελέτη της συλλογής ολοκληρώνεται με την εξέταση του καταληκτήριου ρυθμού των επιστολών της.
description: The subject of this paper is the study of Euthymios Malakes’ corpus of letters. Euthymios Malakes was a writer and bishop of Neai Patrai who lived and acted during the 12th century. His work consists of six speeches, three encomia in honor of the emperor Manuel I Komnenos, two monodies for Alexios Komnenos Kontostefanos and Eustathius of Thessalonica, an epitaph for the bishop of Athens Nikolaos Aghiotheodorites, an epigram and thirty-five letters. In the first chapter, the researcher examines in detail the author's life and activity as a bishop of Neai Patrai, while a brief study of his oeuvres and their handwritten tradition is attempted. The second part presents explicitly the content of his thirty-five epistles. In cases where it is possible, it tries to date some of these or to identify their recipients. In parallel, it is subjoined by the portraits of Malakes' correspondents. In the third and final part of the paper the researcher studies the style and the language of the author's letters. More specifically, the structure of the letters is analyzed, followed by the motifs and any citations which are found in the texts. Finally, the study of Malakes’ corpus is completed by examining the closing rhythm of its letters.

Housing, ecology and technology
Creators: name: Rousseau, David Lewis
Publisher: name: University of British Columbia
Year: 2009

description: Science and technology are the operative languages of people in western industrialized society and, to a large degree, define our relationship with nature. This condition may be traced from its emergence in 16th century philosophical movements and the early development of modern science. This philosophical position has been called “scientific materialism”. In terms of housing, it is apparent in the emphasis on isolation from, and control of nature, and in the conspicuous use of energy and material resources in the pursuit of comfort and luxury. However an emerging ecological trend is beginning to influence housing today. The “natural house” and ‘Baubiologie” approaches are examined both as philosophical movements, and as alternatives to conventional building science. Though the real significance of the ecological agenda is not yet apparent in the mainstream, it is argued that conventional high technology alone has a limited value in providing a more “ecological housing”. The single family suburban home in particular is an inappropriate model for this, even with extreme conservation measures. Environmental, social and feminist critiques are discussed. Facing ecological imperatives will require more than new technology. It will require a shift in fundamental outlook: what is expected from housing, what social and community emphasis is needed, and what luxury features can be discarded. Finding the appropriate uses of technology for providing more ecologically responsible housing will require re examination of the fundamental values on which technological choice is based. In this regard, more collective housing forms hold promise for meeting both social and ecological agendas. Those which attempt to deal with resource allocation, urban and community setting and social change within a context of resource efficiency and modesty are more likely to lead the way towards a more sustainable housing future.

description: Simplified model for current-voltage characteristics of weak links is suggested. It is based on an approach considering the multiple Andreev reflection in metallic Josephson junction. The model allows to calculate current-voltage characteristics of the superconductor - normal metal - superconductor junctions with different thicknesses of normal layer at different temperatures. A hysteretic peculiarity of $V(I)$ dependence is described as result of the negative differential resistance. The current-voltage characteristic of high-$T_c$ composite YBCO +BaPbO${_3}$ were computed.

description: In this work we are trying to analyze Plato's works which are associated with love, the Symposium and Phaedrus with reference to Antoine de Saint-Exypery's work,The Little Prince.Platonic love is analysed and outlined based on the speeches of the guests in Plato's Symposium and the speeches of Phaedrus in order its content and progress become more clear.In Little Prince we find platonic evidence which indicate that the fairytale has philosophical implications linked to love,whether is cordial or sexual.The journey of the soul, according to platonic love, is identified with the journey of The Little Prince in order to indulge in the essence of the concepts love, friendship,romance and the interpersonal relations until they are able to reach the higher state in the world of Ideas and the depiction of the Good which is considered to be the ultimate principle in human life. The completion in both cases occurs with knowledge, conquest of which leads in the transition from earthly to heavenly world
Constraining The Early-Universe Baryon Density And Expansion Rate

description: We explore constraints on extensions to the standard models of cosmology and particle physics which modify the early-Universe expansion rate S = H'/H (parametrized by the effective number of neutrinos N_nu). The constraints on N_nu and the baryon density parameter (eta_B = n_B/n_gamma = 10^(-10)*eta_10) from BBN at 20 minutes are compared with those from the CMB at 400 kyr and LSS at 14 Gyr. BBN provides the strongest constraint on N_nu (1.6 < N_nu < 3.3 at 95% confidence), but a weaker constraint on eta_B. The CMB/LSS best constrain the baryon density (5.9 < eta_10 < 6.4 at 95% confidence), independent of N_nu, but provide a relatively weak N_nu constraint, consistent with N_nu = 3. Using the best fit values and the allowed ranges of the CMB/LSS-derived parameters to calculate the BBN-predicted primordial abundances yields excellent agreement with the observationally inferred abundance of deuterium and good agreement with 4He, confirming the consistency between the BBN and CMB/LSS results. However, the BBN-predicted abundance of 7Li is high, by a factor of 3 or more. We comment on the value of N_nu and a possible anomaly in the matter power spectrum inferred from observations of the Ly-alpha forest. The good agreement between our BBN and CMB/LSS results permit us to constrain any post-BBN entropy production as well as to limit the production of any non-thermalized relativistic particles and, allow us to combine them finding 95% ranges, 1.8 < N_nu < 3.2 and 5.9 < eta_10 < 6.4.

description: The Transformer architecture has become a dominant choice in many domains, such as natural language processing and computer vision. Yet, it has not achieved competitive performance on popular leaderboards of graph-level prediction compared to mainstream GNN variants. Therefore, it remains a mystery how Transformers could perform well for graph representation learning. In this paper, we solve this mystery by presenting Graphormer, which is built upon the standard Transformer architecture, and could attain excellent results on a broad range of graph representation learning tasks, especially on the recent OGB Large-Scale Challenge. Our key insight to utilizing Transformer in the graph is the necessity of effectively encoding the structural information of a graph into the model. To this end, we propose several simple yet effective structural encoding methods to help Graphormer better model graph-structured data. Besides, we mathematically characterize the expressive power of Graphormer and exhibit that with our ways of encoding the structural information of graphs, many popular GNN variants could be covered as the special cases of Graphormer.

description: We report on a densely time sampled polarimetric flux density monitoring of the BL Lac object S5 0716+71 at 86 GHz and 229 GHz with the IRAM 30 m telescope within a coordinated broad spectral band campaign, centred around an INTEGRAL observation during November 10 to 16, 2003. Our aim was to search for signatures of inverse-Compton "catastrophes". At 86 GHz, making use of a new calibration strategy, we reach a relative rms accuracy of the flux density measurements of 1.2%. At this frequency, S5 0716+71 showed no intra-day variability, but showed remarkable inter-day variability with a flux density increase of 34% during the first four observing days, which can not be explained by source extrinsic causes. The 86 GHz linear polarization fraction of S5 0716+71 was unusually large 15.0+-1.8%. Inter-day variability in linear polarization at 86 GHz, with significance level >~95%; sigma_P/=15% and sigma_chi=6 deg., was also observed. From the emission variations at the synchrotron turnover frequency (~86 GHz) we compute an apparent brightness temperature T_B,app>1.4x10^14K at a redshift of 0.3, which exceeds by two orders of magnitude the inverse-Compton limit. A relativistic correction for T_B,app with a Doppler factor delta > 7.8 brings the observed brightness temperature down to the inverse Compton limit. A more accurate lower limit of delta > 14.0, is obtained from the comparison of the 86 GHz synchrotron flux density and the upper limits for the synchrotron self-Compton flux density obtained from the INTEGRAL observations. The relativistic beaming of the emission by this high Doppler factor explains the non-detection of "catastrophic" inverse-Compton avalanches by INTEGRAL.

description: There is a surprising connection between the top quark and Higgs alignment in Gildener-Weinberg multi-Higgs doublet models. Were it not for the top quark and its large mass, the coupling of the 125 GeV Higgs boson $H$ to gauge bosons and fermions would be indistinguishable from those of the Standard Model Higgs. The top quark's coupling to a single Higgs doublet breaks this perfect alignment in higher orders of the Coleman-Weinberg loop expansion of the effective potential. But the effect is still small, $< {\cal{O}}(1\%)$, and probably experimentally inaccessible.

description: Here is studied the presence of absorption components shifted to the violet or the red side of the main spectral line (satellite, or discrete absorption components, i.e. SACs or DACs), in Mg II resonance lines' regions in Be stars and their kinematical characteristics. Namely our objective is to check if exists a common physical structure for the atmospheric regions creating SACs or DACs of the Mg II resonance lines. In order to do this, a statistical study of the Mg II {λλ} 2792.523, 2802.698 Å lines in the spectra of 64 Be stars of all spectral subtypes and luminosity classes is performed. We found that the absorption atmospherical regions where the Mg II resonance lines originated may be formed of several independent density layers of matter which rotate with different velocities. It is attempted also to separate SACs and DACs according to low or high radial velocity. The emission lines were detected only in the earliest and latest spectral subtypes.

description: We present a cautionary study exploring the reliability of the H-delta line in the integrated spectra of galaxies for determining galaxy ages. Our database consists of the observed integrated spectra of ~120 early-type galaxies, of 7 metal-rich globular clusters in M31 and the Galactic globular cluster 47 Tuc, and of the open cluster M67. We have measured H-delta using index definitions designed to assess contamination from the CN molecule in and around H-delta by choosing combinations of bandpasses that both avoid and include a region of CN molecular lines redward of H-delta. We find systematic differences in the ages derived from H-delta measurements among the various definitions when extracting ages from H-delta in old stellar populations with enhanced CN bands due to non-solar abundance ratios. We propose that neighboring CN lines have a strong effect on pseudocontinuum and central bandpass levels. For stellar populations which have non-solar abundance ratios in C and/or N, population synthesis models that do not account for abundance ratio variations cannot reproduce accurately the CN 4216 Åband, which leads to a corresponding inaccuracy in reproducing the various H-delta indices. Hence, caution must be used when extracting galaxy ages from the H-delta line in old stellar populations with significant non-solar abundance ratios.

description: Consider a multiplex network formed by two layers indicating social interactions: the first layer is a friendship network and the second layer is a network of business relations. In this duplex network each pair of individuals can be connected in different ways: they can be connected by a friendship but not connected by a business relation, they can be connected by a business relation without being friends, or they can be simultaneously friends and in a business relation. In the latter case we say that the links in different layers overlap. These three types of connections are called multilinks and the multidegree indicates the sum of multilinks of a given type that are incident to a given node. Previous models of opinion formation on multilayer networks have mostly neglected the effect of link overlap. Here we show that link overlap can have important effects in opinion formation. Indeed, emerging pattern of opinion formation can be significantly influenced by the statistical properties of multilinks, and in particular by the multidegree distribution. To quantitatively address this problem, we study a simple spin model, called the Ashkin-Teller model including 2-body and 4-body interactions between nodes in different layers. Here we fully investigate the rich phase diagram of this model which includes a large variety of phase transitions (PTs). Indeed the phase digram or the model displays continuous, discontinuous, successive discontinuous, and hybrid PTs.

For K*+ and K*- mesons produced in nu_mu CC interactions and decaying into K0 pi+/- we have found the following yields per event: (2.6 +/- 0.2 (stat.) +/- 0.2 (syst.))% and (1.6 +/- 0.1 (stat.) +/- 0.1 (syst.))% respectively, while for the K*+ and K*- mesons produced in nu NC interactions the corresponding yields per event are: (2.5 +/- 0.3 (stat.) +/- 0.3 (syst.))% and (1.0 +/- 0.3 (stat.) +/- 0.2 (syst.))%. The results obtained for the rho00 parameter, 0.40 +/- 0.06 (stat) +/- 0.03 (syst) and 0.28 +/- 0.07 (stat) +/- 0.03 (syst) for K*+ and K*- produced in nu_mu CC interactions, are compared to theoretical predictions tuned on LEP measurements in e+e- annihilation at the Z0 pole. For K*+ mesons produced in nu NC interactions the measured rho00 parameter is 0.66 +/- 0.10 (stat) +/- 0.05 (syst).

description: We present a family of Bell inequalities involving only two measurement settings of each party for N>2 qubits. Our inequalities include all the standard ones with fewer than N qubits and thus gives a natural generalization. It is shown that all the Greenberger-Horne-Zeilinger states violate the inequalities maximally, with an amount that grows exponentially as 2^{{(N-2)}/2}. The inequalities are also violated by some states that do satisfy all the standard Bell inequalities. Remarkably, our results yield in an efficient and simple way an implementation of nonlocality tests of many qubits favorably within reach of the well-established technology of linear optics.

description: BL Lacertae has been the target of several observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration and is one of the best studied blazars at all accessible wavelengths. A recent analysis of the optical and radio variability indicates that part of the radio variability is correlated with the optical light curve. Here we present an analysis of a huge VLBI data set including 108 images at 15, 22, and 43 GHz obtained between 1995 and 2004. The aim of this study is to identify the different components contributing to the single-dish radio light curves. We obtain separate radio light curves for the VLBI core and jet and show that the radio spectral index of single-dish observations can be used to trace the core variability. Cross-correlation of the radio spectral index with the optical light curve indicates that the optical variations lead the radio by about 100 days at 15 GHz. By fitting the radio time lags vs. frequency, we find that the power law is steeper than expected for a freely expanding conical jet in equipartition with energy density decreasing as the square of the distance down the jet as in the Königl model. There is a section of the compact radio jet where the emission is weak such that flares propagating down the jet are bright first in the core region with a secondary increase in flux about 1.0 mas from the core. This illustrates the importance of direct imaging to the interpretation of multi-wavelength light curves that can be affected by several distinct components at any given time. We discuss how the complex behaviour of the light curves and correlations can be understood within the framework of a precessing helical jet model.

description: Quantum networks enable a broad range of practical and fundamental applications spanning distributed quantum computing to sensing and metrology. A cornerstone of such networks is an interface between telecom photons and quantum memories. Here we demonstrate a novel approach based on cavity optomechanics that utilizes the susceptibility of spin qubits to strain. We use it to control electron spins of nitrogen-vacancy centers in diamond with photons in the 1550 nm telecommunications wavelength band. This method does not involve qubit optical transitions and is insensitive to spectral diffusion. Furthermore, our approach can be applied to solid-state qubits in a wide variety of materials, expanding the toolbox for quantum information processing.

description: In this paper, we develop topological data analysis methods for classification tasks on univariate time series. As an application, we perform binary and ternary classification tasks on two public datasets that consist of physiological signals collected under stress and non-stress conditions. We accomplish our goal by using persistent homology to engineer stable topological features after we use a time delay embedding of the signals and perform a subwindowing instead of using windows of fixed length. The combination of methods we use can be applied to any univariate time series and in this application allows us to reduce noise and use long window sizes without incurring an extra computational cost. We then use machine learning models on the features we algorithmically engineered to obtain higher accuracies with fewer features.

description: We consider a harmonic oscillator under periodic driving and coupled to two harmonic-oscillator heat baths at different temperatures. We use the thermofield transformation with chain mapping for this setup, which allows us to study the unitary evolution of the system and the baths up to a time when the periodic steady state emerges in the system. We characterize this periodic steady state, and we show that, by tuning the system and the bath parameters, one can turn this system from an engine to an accelerator or even to a heater. The possibility to study the unitary evolution of the system and baths also allows us to evaluate the steady correlations that build between the system and the baths, and correlations that grow between the baths.

description: The study of correlations and fluctuations can provide evidence for the production of the quark-gluon plasma (QGP) in relativistic heavy ion collisions. Various theories predict that the production of a QGP phase in relativistic heavy ion collisions could produce significant event-by-event correlations and fluctuations in, transverse momentum, multiplicity, etc. Some of the recent results using STAR at RHIC will be presented along with results from other experiments at RHIC. The focus is on forward-backward multiplicity correlations, balance function, charge and transverse momentum fluctuations, and correlations.

description: Στόχος της παρούσας μεταπτυχιακής διατριβής αποτελεί η διερεύνηση της τεχνικής αποτελεσματικότητας σε γεωργικές εκμεταλλεύσεις σιτηρών και ψυχανθών στο Νομό Κιλκίς, ώστε να εξαχθούν συμπεράσματα όσον αφορά τον τρόπο αξιοποίησης των συντελεστών παραγωγής αλλά και βελτίωσης τους, μέσω της ορθολογικότερης χρήσης τους. Η ανάλυση αφορά 100 γεωργικές εκμεταλλεύσεις, με δεδομένα τα οποία συλλέχθηκαν μέσω πρωτογενούς έρευνας με την χρήση ερωτηματολογίων. Η αποτελεσματικότητα των γεωργικών εκμεταλλεύσεων υπολογίστηκε με τη χρήση Περιβάλλουσας Ανάλυσης Δεδομένων (Data Envelopment Analysis), όπου σαν εξαρτημένη μεταβλητή χρησιμοποιήθηκε η ακαθάριστη πρόσοδος σε ευρώ, ενώ σαν ανεξάρτητες μεταβλητές οι συντελεστές παραγωγής του εδάφους (στρέμματα), της οικογενειακής και ξένης εργασίας (ημέρες), καθώς και του μεταβλητού κεφαλαίου (ευρώ), οπού σε αυτό περιλαμβάνονται τα κόστη λιπασμάτων, φυτοφάρμακων και καυσίμων. Τα αποτελέσματα έδειξαν ότι για τη βελτίωση της αποτελεσματικότητας των γεωργικών εκμεταλλεύσεων, οι εισροές πρέπει να μειωθούν κατά 32.6% (VRS) με δεδομένο επίπεδο εκροών, ενώ μόνο 8 γεωργικές εκμεταλλεύσεις παρουσιάζουν αρίστη τεχνική αποτελεσματικότητα. Ακόμη, οι εκμεταλλεύσεις με μεγάλο αριθμό στρεμμάτων, απαιτούν μεγαλύτερες δαπάνες παραγωγής, μειώνοντας την αποτελεσματικότητα και το κέρδος των παραγωγών, σε αντίθεση με τις μικρότερες γεωργικές εκμεταλλεύσεις που χρησιμοποιούν λιγότερες δαπάνες σε καύσιμα, φυτοφάρμακα και λιπάσματα.
description: The purpose of this postgraduate dissertation is to analyze the technical efficiency of cereal and leguminous farms in the Kilkis peripheral unit in order to draw conclusions on how to utilize the production factors but also how to improve them through their more rational use. The analysis concerns 100 farms, with data collected through primary research using questionnaires. Efficiency of agricultural holdings was calculated using Data Envelopment Analysis, where as a dependent variable the gross income in euro was used, while as independent variables the factors of production of land (acres), family and foreign labor (days) , as well as the variable capital (euro), including the costs of fertilizers, pesticides and fuels. The results showed that in order to improve the efficiency of farms, inputs should be reduced by 32.6% (VRS) at a given output level, while only 8 farms have excellent technical efficiency. In addition, farms with a large number of acres require higher production costs, reducing the efficiency and profit of derivatives, as opposed to smaller farms that use less fuel, pesticide and fertilizer costs.
