Πνευμονοφόρα γαστερόποδα

description: Η έρευνα έγινε στην παλιά κοίτη του ποταμού Στρυμώνα στο βόρειο τμήμα της λίμνης Κερκίνης όπου συνυπήρχαν τρία είδη πνευμονοφόρων η P. acuta η L. stagnalis και η L. Auricularia. Η χωροδιάταξη είναι κατά ομάδες και στα τρία είδη. Το βάθος του νερού επηρεάζει το τύπο χωροδιάταξης των ειδών L. stagnalis και L. aurocularia. H Π. acuta υπερκυριαρχεί στην επιφάνεια ενώ στα βαθύτερα στρώματα τα 3 είδη εμφανίζουν όμοιες και χαμηλές πυκνότητες. Η δυναμική των τριών πληθυσμών επηρεάζεται από την διακύμανση της στάθμης του νερού και τη φυτική βιομάζα H L. auricularia εμφανίζει ετήσιο κύκλο ζωής με 1 ή 2 γενιές/έτος. Η L. stagnalis εμφανίζει διετή κύκλο ζωής και εισάγει 2 γενιές κατά το δεύτερο έτος. Η P. acuta εμφανίζει ετήσιο κύκλο ζωής με 3 γενιές/έτος. Η γενιά της άνοιξης ωριμάζει γρήγορα και ωαποθέτει καθ΄ολη τη διάρκεια του καλοκαιριού-φθινοπώρου αλληλεπικαλύπτονται και ένα μεγάλο τους ποσοστό διαχειμάζει και αναπαράγεται την επόμενη άνοιξη. Ο αριθμός των αυγών/ωαπόθεση και γονιμότητα αυξάνονται με την ηλικία. Η γενιά της άνοιξης έχει μεγαλύτερο αναπαραγωγικό δυναμικό από τις άλλες δύο γενιές του ίδιου έτους. Η μόλυνση με τρηματώση παράσιτα αφορά μόνον τα ώριμα σαλιγκάρια και τα ανώριμα της άνοιξης. Η γενιά τηα άνοιξης εμφανίζει την υψηλότερη παραγωγικότητα και τον μικρότερο χρόνο ανανέωσης της βιομάζας. Οι τρείς γενιές έχουν ίδια ετήσια ικανότητα ανανέωσης της βιομάζας. Το 80% των σαλιγκαριών που διαχειμάζουν εμφανίζουν αάξηση βάρους στη διάρκεια του χειμώνα. Το κόστος συντήρησης είναι υψηλό Η ενέργεια που επενδύεται στην αύξηση αυξάνει μέχρι την ηλικία της γεννητικής ωρίμανσης. Η ενέργεια που επενδύεται στην αναπαραγωγή αυξάνει με την ηλικία...

Modelling the swarming behaviour of army ants
Creators: name: Watmough, James
Publisher: name: University of British Columbia
Year: 2008

description: A model of the collective motion of a group of social insects interacting through a trail network is developed around a set of simple rules. The model assumes that individuals interact with the existing trail network both by following the trails, and by adding to and reenforcing trails. The main hypothesis of the model is that the mechanics of the motion of the individuals are sufficient to determine the collective motion of the group, or equivalently, that the parameters governing the behaviour of the individuals are sufficient to determine the patterns of the trail networks produced. Both a simulation and a mathematical model are derived from this same set of rules. The mathematical model is derived for a single spatial dimension to study the propagation of the raiding column. The results are compared both to the swarming behaviour of army ants observed in the field, and to the results of simulations of other authors which were based on different assumptions. We conclude that it is possible that many aspects of the swarming pattern are controlled by the parameters governing the behaviour of the individual.

Caught in the Act: Core-powered Mass-loss Predictions for Observing Atmospheric Escape

description: Past studies have demonstrated that atmospheric escape by the core-powered mass-loss mechanism can explain a multitude of observations associated with the radius valley that separates the super-Earth and sub-Neptune planet populations. Complementing such studies, in this work, we present a shortlist of planets that could be losing their atmospheres today if their evolution is indeed primarily dictated by core-powered mass-loss. We use Bayesian inference analysis on our planet evolution and mass-loss model to estimate the posteriors of the parameters that encapsulate the current state of a given planet, given their published masses, radii and host star properties. Our models predict that the following planets could be losing their atmospheres today at a rate $\gtrsim 10^7$ g/s at 50\% confidence level: pi Men c, Kepler-60 d, Kepler-60 b, HD 86226 c, EPIC 249893012 b, Kepler-107 c, HD 219134 b, Kepler-80 e, Kepler-138 d and GJ 9827 d. As a by-product of our Bayesian inference analysis, we were also able to identify planets that most-likely harbor either secondary atmospheres abundant with high mean-molecular weight species, low-density interiors abundant with ices, or both. The planets belonging to this second category are WASP-47 e, Kepler-78 b, Kepler-10 b, CoRoT-7 b, HD 80653 b, 55 Cnc e and Kepler-36 b. While the aforementioned lists are by no means exhaustive, we believe that candidates presented here can serve as useful input for target selection for future surveys and for testing the importance of core-powered mass-loss in individual planetary systems.

description: Antivortices in ferromagnetic thin-film elements are in-plane magnetization configurations with a core pointing perpendicular to the plane. By using micromagnetic simulations, we find that magnetic antivortices gyrate on elliptical orbits similar to magnetic vortices when they are excited by alternating magnetic fields or by spin-polarized currents. The phase between high-frequency excitation and antivortex gyration is investigated. In case of excitation by spin-polarized currents the phase is determined by the polarization of the antivortex, while for excitation by magnetic fields the phase depends on the polarization as well as on the in-plane magnetization. Simultaneous excitation by a current and a magnetic field can lead to a maximum enhancement or to an entire suppression of the amplitude of the core gyration, depending on the angle between excitation and in-plane magnetization. This variation of the amplitude can be used to experimentally distinguish between spin-torque and Oersted-field driven motion of an antivortex core.

description: We show that the correlator of three large charge operators with minimal scaling dimension can be computed semiclassically in CFTs with a $U(1)$ symmetry for arbitrary fixed values of the ratios of their charges. We obtain explicitly the OPE coefficient from the numerical solution of a nonlinear boundary value problem in the conformal superfluid EFT in $3d$. The result applies in all three-dimensional CFTs with a $U(1)$ symmetry whose large charge sector is a superfluid.

description: We present results from a study of the X-ray cluster population that forms within the CLEF cosmological hydrodynamics simulation, a large N-body/SPH simulation of the Lambda CDM cosmology with radiative cooling, star formation and feedback. The scaled projected temperature and entropy profiles at z=0 are in good agreement with recent high-quality observations of cool core clusters, suggesting that the simulation grossly follows the processes that structure the intracluster medium (ICM) in these objects. Cool cores are a ubiquitous phenomenon in the simulation at low and high redshift, regardless of a cluster's dynamical state. This is at odds with the observations and so suggests there is still a heating mechanism missing from the simulation. Using a simple, observable measure of the concentration of the ICM, which correlates with the apparent mass deposition rate in the cluster core, we find a large dispersion within regular clusters at low redshift, but this diminishes at higher redshift, where strong "cooling-flow" systems are absent in our simulation. Consequently, our results predict that the normalisation and scatter of the luminosity-temperature relation should decrease with redshift; if such behaviour turns out to be a correct representation of X-ray cluster evolution, it will have significant consequences for the number of clusters found at high redshift in X-ray flux-limited surveys.

description: In this article we deal with one-dimensional inverse problems concerning the Burgers equation and some related nonlinear systems (involving heat effects and/or variable density). In these problems, the goal is to find the size of the spatial interval from some appropriate boundary observations of the solution. Depending on the properties of the initial and boundary data, we prove uniqueness and non-uniqueness results. In addition, we also solve some of these inverse problems numerically and compute approximations of the interval sizes.

description: We show that all the parameters which destabilize the weak scale can be taken around the weak scale in the MSSM without conflicting with the SM Higgs mass bound set by LEP experiment. The essential point is that if the lightest CP-even Higgs h in the MSSM has only a small coupling to Z boson, g_{ZZh}, LEP cannot generate the Higgs sufficiently. In the scenario, the SM Higgs mass bound constrains the mass of the heaviest CP-even Higgs H which has the SM like g_{ZZH} coupling. However, it is easier to make the heaviest Higgs heavy by the effect of off-diagonal elements of the mass matrix of the CP-even Higgs because the larger eigenvalue of 2 times 2 matrix becomes larger by introducing off-diagonal elements. Thus, the smaller stop masses can be consistent with the LEP constraints. Moreover, the two excesses observed at LEP Higgs search can naturally be explained as the signals of the MSSM Higgs h and H in this scenario. One of the most interesting results in the scenario is that all the Higgs in the MSSM have the weak scale masses. For example, the charged Higgs mass should be around 130 GeV. This looks inconsistent with the lower bound obtained by the b --> s gamma process as m_{H^\pm}>350GeV. However, we show that the amplitude induced by the charged Higgs can naturally be compensated by that of the chargino if we take the mass parameters by which the little hierarchy problem can be solved. The point is that the both amplitudes have the same order of magnitudes when all the fields in the both loops have the same order of masses.

description: Στην παρούσα εργασία εξετάζονται τα Ιβύκεια αποσπάσματα που αναφέρονται στην τρωϊκή έριδα και τον έρωτα. Ο άξονας έρως-έρις αποδεικνύεται ιδιαίτερα χρήσιμος τόσο θεματικά, αφού συχνά τα δύο μοτίβα συνδυάζονται άμεσα ή έμμεσα, όσο και ποιητολογικά, εφόσον ο λυρικός "ερωτροπεί" και "ερίζει" με την παράδοση, προκειμένου να συνθέσει τη δική του ποιητική πρόταση. Στο Α' κεφ. προτείνεται μια νέα ερμηνευτική προσέγγιση της ωδής που απευθύνεται στον Πολυκράτη(5151), ενώ διατυπώνεται μια εικασία σχετικά με την ενότητα του προκειμένου ποιήματος και ενδεχομένως της ωδής ως είδους.

Στο τελευταίο τμήμα του γίνεται λόγος για τα τρία γνωστά ως "ερωτικά" αποσπάσματα του Ρηγίνου(286-288 DAV), όπου μύθος και σύγχρονη του δημιουργού πραγματικότητα διαπλέκονται, προκειμένου να συγκροτηθεί μυθοπλασία ερωτική. Στο Γ' κεφ. ανασυγκροτείται, δειγματοληπτικά ως προς την επιλογή των εξεταζόμενων προσώπων, το ηρωϊκό "ήθος" : όνομα, γενεαλογία και επίθετα ως προσσδιορισμοί συνθέτουν την ταυτότητα των ηρώων αποκαλύπτοντας καίριες ιδιότητές τους στο πλαίσιο της λυρικής ωδής
description: The author of the dissertation examines the Ibycean fragments which refer to the war of Troy and to erotic myths. The axis eros-eris(love-strife) proves to be useful not only thematically, because of the often direct or indirect combination of the motifs, but also poetologically, since the lyric "flirts" with and "fights" against the tradition, in order to articulate his own poetic voice. Throughout chapter A' anew approach is suggested as far as the ode which is addressed to polycrates(5151) is concerned, while a hypothesis is being stated about the unity of the poem and perhaps of the lyricode in general. In chapter B' the examination of other fragments which refer to the war of Troy and eros reveal the depth and the scope of the Ibycean reception of the myth. In the last part, the three known as "erotic" fragments are analysed(286-288 DAV); while myth and the reality contemporary to the poet intermingle, the lyric creates the myth of eros. In chapter C' the heroic character is examined : name, genealogy and epithets constitute the identity of the heroes revealing their main characteristics in the lyric ode

description: The plants, Althaea officinalis, Tilia cordata and Psidium guaja have been used traditionally to treat respiratory infection symptoms. Flowers of A. officinalis and leaves of T. cordata and P. guaja have been used to treat cough, sore throat, catarrh, oral and pharyngeal mucosa irritation. Therefore, this study was designed to examine the antibacterial and antibiofilm effects of these plants individually as well as in combination, as a formula against respiratory infections causing pathogens. The tested pathogens were Extended Spectrum Beta-Lactamase producing Escherichia coli (ESBL), Beta-Lactamase producing Escherichia coli (BL), Beta-Lactamase producing Klebsiella pneumoniae (BL), Beta-Lactamase producing Pseudomonas aeruginosa (BL), Enterobacter cloacae, and Beta-Lactamase producing Staphylococcus aureus (BL). The tested plants were extracted using ethanol and then fractionated using different polarity solvents (hexane, ethyl acetate and water). Disc diffusion and microdilution (Minimum Inhibitory Concentration) methods were used to evaluate the antibacterial activity while the antibiofilm activity was tested using crystal violet assay. The results showed that A. officinalis and T. cordata extracts and fractions exhibited weak antibacterial activity having MIC values ranged from 6.25 to 12.5 mg/mL. P. guaja exhibited moderate antibacterial activity with MIC values ranged from 6.25 to 1.56 mg/mL. Combination between these plants extracts and fractions in equal proportion provides stronger antibacterial (with MIC values ranged from 6.25 to 0.8 mg/mL) and antibiofilm activities (MBIC50 was 0.2 mg/mL). Therefore, this study provides a valuable scientific knowledge to support the use of plants in combination rather than individually.

description: We describe the effective Lorentz forces on the ions of a generic insulating system in an magnetic field, in the context of Born-Oppenheimer ab-initio molecular dynamics. The force on each ion includes an important contribution of electronic origin, which depends explicitly on the velocity of all other ions. It is formulated in terms of a Berry curvature, in a form directly suitable for future first principles classical dynamics simulations based {\it e.g.,} on density functional methods. As a preliminary analytical demonstration we present the dynamics of an H$_2$ molecule in a field of intermediate strength, approximately describing the electrons through Slater's variational wavefunction.

description: We confirm by explicit computation the conjectured all-orders iteration of planar maximally supersymmetric N=4 Yang-Mills theory in the nontrivial case of five-point two-loop amplitudes. We compute the required unitarity cuts of the integrand and evaluate the resulting integrals numerically using a Mellin--Barnes representation and the automated package of ref.~[1]. This confirmation of the iteration relation provides further evidence suggesting that N=4 gauge theory is solvable.

description: Conductance signatures that signal the presence of Majorana zero modes in a three terminal nanowire-topological superconductor hybrid system are analyzed in detail, in both the clean nanowire limit and in the presence of non-coherent dephasing interactions. In the coherent transport regime for a clean wire, we point out contributions of the local Andreev reflection and the non-local transmissions toward the total conductance lineshapes while clarifying the role of contact broadening on the Majorana conductance lineshapes at the magnetic field parity crossings. Interestingly, at larger $B$-field parity crossings, the contribution of the Andreev reflection process decreases which is compensated by the non-local processes in order to maintain the conductance quantum regardless of contact coupling strength. In the non-coherent transport regime, we include dephasing that is introduced by momentum randomization processes, that allows one to smoothly transition to the diffusive limit. Here, as expected, we note that while the Majorana character of the zero modes is unchanged, there is a reduction in the conductance peak magnitude that scales with the strength of the impurity scattering potentials. Important distinctions between the effect of non-coherent dephasing processes and contact-induced tunnel broadenings in the coherent regime on the conductance lineshapes are elucidated. Most importantly our results reveal that the addition of dephasing in the set up does not lead to any notable length dependence to the conductance of the zero modes, contrary to what one would expect in a gradual transition to the diffusive limit. We believe this work paves a way for a systematic introduction of scattering processes into the realistic modeling of Majorana nanowire hybrid devices and assessing topological signatures in such systems in the presence of non-coherent scattering processes.

description: Extrasolar planets as light as a few Earths are now being detected. Such planets are likely not gas or ice giants. Here, we present a study on the possible properties of the small and cold extrasolar planets, applied to the case of the recently discovered planet OGLE-2005-BLG-390Lb (Beaulieu et al. 2006). This planet (5.5[+5.5/-2.7] Earth masses) orbits 2.6[+1.5/-0.6]-astronomical units away from an old M-type star of the Galactic Bulge. The planet should be entirely frozen given the low surface temperature (35 to 47 K). However, depending on the rock-to-ice mass ratio in the planet, the radiogenic heating could be sufficient to make the existence of liquid water within an icy crust possible. This possibility is estimated as a function of the planetary mass and the illumination received from the parent star, both being strongly related by the observational constraints. The results are presented for water-poor and water-rich planets. We find that no oceans can be present in any cases at 9-10 Gyr, a typical age for a star of the Bulge. However, we find that, in the past when the planet was < 5-billion-years old, liquid water was likely present below an icy surface. Nevertheless, the planet is now likely to be entirely frozen.

description: We report on the first ever detection of circular polarization in molecular lines forming in magnetic regions on the surfaces of active stars. The new observations were obtained with the high-resolution spectropolarimeter ESPaDOnS recently installed at the Canada-France-Hawaii Telescope. In July 2005 we carried out a survey of 17 G-K-M stars including active main-sequence dwarfs and RS CVn-type giants and subgiants. All stars were found to possess surface magnetic fields producing average atomic Stokes V signals of 0.05% to 0.5%. Three stars clearly showed circular polarization in molecular lines of 0.5% to 1%. The molecular Stokes V signal is reminiscent of that observed in sunspots.

description: Σκοπός της εργασίας ήταν η μελέτη των ανατομικών και λειτουργικών καρδιακών προσαρμογών καθώς και της αερόβιας ικανότητας και της καρδιακής δραστηριότητας του παρασυμπαθητικού νευρικού συστήματος αθλητών πετοσφαίρισης υψηλού επιπέδου κατά τον ετήσιο προπονητικό κύκλο τους. Η μελέτη έγινε σε 12 επαγγελματίες αρρένες αθλητές ηλικίας 24,0+-4,9 ετών, ομάδας Α' Εθνικής κατηγορίας της Θεσσαλονίκης. Ολοι οι αθλητές υποβλήθηκαν σε ανθρωπομετρικές εξετάσεις, λιπομέτρηση, σπιρομέτρηση, ηλεκτροκαρδιογράφημα, υπερηχοκαρδιογράφημα, δοκιμασία κόπωσης και εργοσπιρομέτρσηση, προσδιορισμό γαλακτικού οξέος ηρεμίας και μέγιστης κόπωσης και συνεχή 24ωρη καταγραφή του καρδιακού ρυθμού. Οι πιο σημαντικοί δείκτες που καταγράφηκαν από τις δοκιμασίες ήταν το ύψος και το βάρος, το επί τοις εκατό λίπος(ΣΛ), η ζωτική χωρητικότητα(VC), η δυναμική ζωτική χωρητικότητα(FVC), η καρδιακή συχνότητα ηρεμίας(ΚΣ), ο τελοδιστολικός όγκος της αριστερής κοιλίας(EDV), η μάζα της αριστερής κοιλίας(LVM), το κλάσμα εξώθησης της αριστερής κοιλίας(%EF), η μέγιστη πρόσληψη οξυγόνου(V02max), η διάρκεια κόπωσης, το γαλακτικό οξύ(Γ0 max) και η μεταβλητότητα της καρδιακής συχνότητας(HRV). Από τις μετρήσεις που έγιναν διαπιστώνεται ότι στη διάρκεια του ετήσιου προπονητικού κύκλου των αθλητών πετοσφαίρισης εμφανίζονται σημαντικές καρδιοαναπνευστικές προσαρμογές, που χάνονται όμως κατά τη θερινή διακοπή των προπονήσεων
description: The aim of this work was to study the anatomical and functional adaptations of the heart, as well as the aerobic capacity and the cardiac parasympathetic mervous system's activity of elite volleyball athletes during their annual training season. The study was performed on 12 professional male athletes aged 24,0+-4,9 years. They all submitted to anthropomentric measurements, fat estimation, spirometry, electracardiogram, echocardiogram, treadmill exercise testing, ergospirometry, measurement of blood lactate and ambulatory continous recording of the heart rate. The most important indicators that were recorded from the tests were height, body fat (%), vital capacity, forced vital capacity, resting and maximal heart rate, end-diastolic volume of the left ventricle, left ventricle mass, % EF, Vo2max, exercise duration, maximal lecture and heart rate variability(HRV). For all the tests which were performed it can supported that during the volleyball annual training season significant cardiorespiratory changes appear, that are restored after the summer holidays

Can you win at TETRIS?

Publisher: name: University of British Columbia

description: TETRIS is a popular video game in which you try to fill rows in a rectangular well using a sequence of tetrominoes chosen by the machine. Each time you succeed in filling a row, it is deleted from the well. Your game ends when you have stacked pieces up to the top of the well. I build a model of TETRIS and analyze the worst-case scenario, in which the machine is treated as an adversary. I say you have a winning strategy when you can make your game last indefinitely. I construct winning strategies for some subsets of the TETRIS pieces, and prove that none exists for some others. Finally, I compare these analytic results to some empirical average-case data that I obtain from a passive survey of TETRIS players.

description: Η παρούσα διατριβή διερευνά τη θεωρία και τη χρήση της μεταφοράς στην πραγματεία του Λογγίνου "Περί Υψους". Στο επίπεδο της θεωρίας επιχειρείται η ένταξη των απόψεων του Λογγίνου για τη μεταφορά στη θεωρητική παράδοση των προηγούμενων αιώνων(Αριστοτέλη, Δημήτριο "Περί Ερμηνείας", Διονύσιο τον Αλικαρνασσέα, "Ρητορική προς Ερέννιον", Κικέρωνα και το μεταγενέστερο Κοϊντιλιανό) και ειδικότερα στο πλαίσιο της συζήτησης για το ύφος του πεζού λόγου με βασικό ζητούμενο την ορθή χρήση της μεταφοράς. Ο Λογγίνος αποκλίνει ουσιαστικά από τις απόψεις των άλλων θεωρητικών, καθώς προτείνει ως μοναδικό κριτήριο αντιμετώπισης συγκεκριμένων προβλημάτων(πλήθος, τόλμη, επαλληλία) το πάθος και το ύψος, με τα οποία η μεταφορά βρίσκεται σε αμφίδρομη σχέση. Οσον αφορά στην χρήση της μεταφοράς από το Λογγίνο επισημαίνεται η παραπάνω σχέση και διερευνώνται οι μέθοδοί του για την ανάδειξη των μεταφορών σε επίπεδο : α)λέξης β)περιόδου ή κεφαλαίου γ)κειμένου. Στο (γ) διαπιστώνεται η ύπαρξη ενός κεντρικού μεταφορικού δικτύου και εντοπίζονται οι μεταφορικοί όροι που δηλώνουν το υψηλό και εκείνοι που περιγράφουν το μέγεθος και την εντασή του. Οι περιοχές από τις οποίες αντλούνται οι παραπάνω μεταφορές είναι κυρίως τρείς : α) οι αγώνες β) η ενθουσιαστική μανία γ) δυναμικά φυσικά φαινόμενα. Και οι τρείς χρησιμοποιούνται για να περιγραφούν α) ο υψηλός λόγος β) οι μεγάλοι συγγραφείς γ) η ακροαματική πρόσληψης του ύψους
description: This thesis is investigates the theory of metaphor and its use in Longinus'treatise "On Sublime". As far as theory is concerned its aims at placing L.'s. views on metaphor withn the tradition of previous theorists(Aristotle, Demetrius "On style", Dionysious of Halicarnassus, "Rhetoric and Herennium", Cicero and, the later, Quisdilian). In particular, this thesis aims discussion on prose style. L. deviates from other theorists' views, for the proposes pathos and sublime as a unique criterion of solution to specific problems such as quantity, audacity, continuity. Metaphor has a low-way relation to pathos and sublime. As far as the use of metaphor in L. is concerned the above relation is underlined and investigated his methods to elevating of metaphors in regarding : a) of word b) of period or chapter c) of the text. In the case of (c) we find out the existence of a central metaphorical net and we locate the metaphorical words, which declare the sublime and those which describe its size and intensity. The areas from which the metaphors of intensity are derived are mainly three : a)the contests' b0the enthousiastic mania c)dynamic natural phenomena. All three are used to describe a) the sublime writing b)the sublime writers and c)the audience's perception of sublime

description: Ο ιταλός ζωγράφος Τζιόρτζιο ντε Κίρικο γεννήθηκε στο Βόλο το 1888 και εμπνεύστηκε από τον πολιτισμό και την ωραιότητα της Ελλάδας για να δημιουργήσει μεγάλο μέρος από τα έργα του. Η "μεταφυσική" του τέχνη(πίνακες, σχέδια, χαρακτικά, γλυπτά, θεατρικά σκηνικά-κοστούμια) και το πλούσιο συγγραφικό του έργο, διαπνέονται από τη νοσταλγία της Ελλάδας, ως τόπου που έλαβε μυθικές διαστάσεις στη συνείδησή του. Η κλασική του παιδεία και η γνώση της αρχαίας ελληνικής τέχνης και γραμματείας ήταν στοιχεία που διαμόρφωσαν μια σύνθετη προσωπικότητα καλλιτέχνη-ποιητή-συγγραφέα και "ηρωα" της σκέψης, που εμπλουτίστηκε από τα πρωτοποριακά καλλιτεχνικά ρεύματα των αρχών του 20ου αι. Ο χώρος της μνήμης που δεν επηρεάζεται από την προοδευτική εξέλιξη της ιστορίας, μυθοποίησε το όραμα του ελληνικού κόσμου(αγάλματα, ναοί, πλατείες, αρχαιολόγοι, ομηρικοί και τραγικοί ήρωες, φιλόσοφοι, θεοί, ελληνικά τοπία) και το τοποθέτησε σ'ενα αινιγματικό και απρόσιτο παρελθόν που ξαναζεί το μέλλον του σ'ενα αιώνιο παρόν. Η λεπτομερής ανάλυση και παραβολή των γραπτών του καλλιτέχνη και των ζωγραφικών θεμάτων του, επιτρέπει την ανάπλαση της δημιουργικής του προσωπικότητας και αποδεικνύει τη συνέπεια ήθους και ύφους της ολοκληρωμένης προσφοράς του στο χώρο της εικαστικήςκαι της συγγραφικής δημιουργίας
description: The italian painter Giorgio de Chirico was born in Volos(Thessaly) in 1888. He was inspired by Greek civilization and beauty that influenced that creation of a great part of his work. His "metaphysical" art (painting, designs, stamps, sculptures, theatrical sceneries/custunes) and rich literary work are traversed by the nostalgia for Greece, a place that assumed a mythical dimension in his conscience. His classical education and knowledge regarding ancient Greek art and literature were elements that molded a complex personality of an artist-poet-author-and "hero" of the thought, that was further enriched by the innorative artistic currents in the beggining of the 20th century. The space of memory which cannot be affected by the progressive evolution of history, rendered the vision of the Greek would(statues, temples, squares, archeologists, homeric and tragic heroes, philosophers, gods, greek landscapes) a myth and placed it in an ambiquous and unapproachable past that revives its future in an eternal present. A detailed analysis and comparison of the artist's writings as well as the themes presented in his paintings allows for the re-creation of his creative personality and proves the constistency of "ethos" and style that charactirize his entire contribution in the wirld of fine arts and literaty creativity

description: When conducting inference on partially identified parameters, confidence regions may cover the whole identified set with a prescribed probability, to which we will refer as set coverage, or they may cover each of its point with a prescribed probability, to which we will refer as point coverage. Since set coverage implies point coverage, confidence regions satisfying point coverage are generally preferred on the grounds that they may be more informative. The object of this note is to describe a decision problem in which, contrary to received wisdom, point coverage is clearly undesirable.

description: The possibility is examined that a model based on space noncommutativity of linear type can explain why photons from distant sources with multi-TeV energies can reach earth. In particular within a model in which space coordinates satisfy the algebra of SU(2) Lie group, it is shown that there is the possibility that the pair production through the reaction of CMB and energetic photons would be forbidden kinematically.

description: Weakly coupled, almost massless, spin 0 particles have been predicted by many extensions of the standard model of particle physics. Recently, the PVLAS group observed a rotation of polarization of electromagnetic waves in vacuum in the presence of transverse magnetic field. This phenomenon is best explained by the existence of a weakly coupled light pseudoscalar particle. However, the coupling required by this experiment is much larger than the conventional astrophysical limits. Here we consider a hypothetical self-interacting pseudoscalar particle which couples weakly with visible matter. Assuming that these pseudoscalars pervade the galaxy, we show that the solar limits on the pseudoscalar-photon coupling can be evaded.

A study of phase resetting, mutual entrainment, and modified ventricular parasystole using a model of coupled heart cells
Creators: name: Foster, Toni
Publisher: name: University of British Columbia
Year: 2008

description: Several aspects of cardiac electrophysiology including phase-resetting and entrainment are investigated through the dynamic interactions of coupled mathematical models of cardiac cells. Unlike previous studies of cell interaction which have used simplified models of a general cardiac cell or oscillators characterized only by their phase transition curves the present work incorporates the more physiologically realistic cell models of the Hodgkin-Huxley type. Furthermore, this caricature of the heart includes models representing cells from each of the major components of the heart's electrical conduction system, the SA node, AV node, Purkinje fibre network, and ventricular myocardium. Since there does not exist a model for an AV node cell, a new model is created by modifying the SA node cell equations. Because spontaneously firing cardiac cells exhibit a wide range of oscillation frequencies, certain physiologically based parameters in the model equations were altered to produce a similar range of intrinsic frequencies in the model cells. These model cells are coupled by assuming that direction-dependent and purely resistive coupling currents flow between them. Furthermore, these coupling currents incorporate a time delay rep-resenting the intercell impulse propagation time which is significant between different regions of the heart. Each of the conduction components, the SA and AV nodes, Purkinje fibre network, and ventricular myocardium, can be modelled with either one or several of their model cells. These model components can then be coupled with appropriate conductances and propagation time delays to model the spread of waves of excitation from one region of the heart to another. When cells interact, their intrinsic cycles may be perturbed. These alterations or phase-shifts which determine the ultimate rhythm of coupled cells are studied for various combinations of the model cells and different strengths of interaction. In each case results are plotted in a phase response curve whose shape is found to depend on such things as coupling conductance and cell frequency. Phase-resetting is a prerequisite to the entrainment of cells in which there are m cycles of one cell for every n cycles of another. The phenomenon of entrainment is studied as part of the behavior of a healthy heart where it provides the mechanism by which cells synchronize to produce a single wave of excitation for each heartbeat. Mutual entrainment is also studied in a commonly occurring pathological situation, modulated ventricular parasystole. It is demonstrated that the particular pattern of m:n entrainment is dependent on the differences in the intrinsic frequencies of the cells and on the strength of the interaction. Results obtained using different types of model cells located in different regions of the heart are compared and contrasted to those of previous studies of adjacent cells which are identical.
