Μία σειρά δεικτών επιστημικής τροπικότητας μελετήθηκαν σε επίπεδο περικειμένου (πρόταση ή παράγραφος, όπου δεν ήταν επαρκής η ανάλυση σε επίπεδο πρότασης), προκειμένου να διαφανεί ο τρόπος που χρησιμοποιούν οι μη-φυσικοί ομιλητές της Ν.Ε. για να εκφράσουν την προσωπική τους θέση/άποψη χωρίς να παραβιάζουν τους κώδικες ευγένειας που επιβάλλει η κοινωνία.
description: The thesis explores the semantic area of Epistemic Modality in Modern Greek, by means of a corpus-based research on informal letter-writing. A comparative, quantitative study was performed between written corpora of non-native informants with various language backgrounds and Greek native speakers. A number of epistemic markers were contextualised to reveal the ways they are used in order to express the speaker's stance while performing a number of discourse-pragmatic functions without violating the societal norms of politeness.

description: If inflation is to be considered in an unbiased way, as possibly originating from one of a wide range of underlying theories, then observations need not be simply applied to reconstructing the inflaton potential, V(ϕ), or a specific kinetic term, as in DBI inflation, but rather to reconstruct the inflationary action in its entirety. We discuss the constraints that can be placed on a general single field action from measurements of the primordial scalar and tensor fluctuation power spectra and non-Gaussianities. We also present the flow equation formalism for reconstructing a general inflationary Lagrangian, L(X,ϕ), with X={1/2}\partial_μϕ\partial^μϕ, in a general gauge, that reduces to canonical and DBI inflation in the specific gauge \partial L/\partial X = c_s^{-1}.

Towards a Koopman theory for dynamical systems on completely regular spaces

description: The Koopman linearization of measure-preserving systems or topological dynamical systems on compact spaces has proven to be extremely useful. In this article we look at dynamics given by continuous semiflows on completely regular spaces which arise naturally from solutions of PDEs. We introduce Koopman semigroups for these semiflows on spaces of bounded continuous functions. As a first step we study their continuity properties as well as their infinitesimal generators. We then characterize them algebraically (via derivations) and lattice theoretically (via Kato's equality). Finally, we demonstrate-using the example of attractors-how this Koopman approach can be used to examine properties of dynamical systems.

description: We compute the two-loop heavy quark jet-function in the heavy quark limit. This is one of the key ingredients in next-to-next-to-leading order (NNLO) and next-to-next-to-leading-log order (NNLL) computations of the invariant mass distribution of top-jets at a future e+e- collider. The shape of the top invariant mass distribution is affected by large logs which we compute at NNLL order. Exploiting the non-abelian exponentiation theorem, a definition of the top jet-mass is given which is transitive and whose renormalization group evolution is determined by the cusp-anomalous dimension to all orders in perturbation theory. Relations of the jet-mass to the pole, MSbar, and 1S masses are presented at two-loop order.

description: Large spin cold atom systems can exhibit novel magnetic properties which do not appear in usual spin-1/2 systems. We investigate the SU(4) resonating plaquette state in the three dimensional cubic optical lattice with spin-3/2 cold fermions. A novel gauge field formalism is constructed to describe the Rokhsar-Kivelson type of Hamiltonian and a duality transformation is used to study the phase diagram. Due to the proliferation of topological defects, the system is generally gapped for the whole phase diagram of the quantum model, which agrees with the recent numerical studies. A critical line is found for the classical plaquette system, which also corresponds to a quantum many-body wavefunction in a "plaquette liquid phase".

Prompt Shocks in the Gas Disk Around a Recoiling Supermassive Black Hole Binary

description: Supermassive black hole binaries (BHBs) produced in galaxy mergers recoil at the time of their coalescence due to the emission of gravitational waves (GWs). We simulate the response of a thin, 2D disk of collisionless particles, initially on circular orbits around a 10^6 M_sun BHB, to kicks that are either parallel or perpendicular to the initial orbital plane. Typical kick velocities (v_k) can exceed the sound speed in a circumbinary gas disk. While the inner disk is strongly bound to the recoiling binary, the outer disk is only weakly bound or unbound. This leads to differential motions in the disturbed disk that increase with radius and can become supersonic at ~700 Schwarzschild radii for v_k ~500 km/s, implying that shocks form beyond this radius. We indeed find that kicks in the disk plane lead to immediate strong density enhancements (within weeks) in a tightly wound spiral caustic, propagating outward at the speed v_k. Concentric density enhancements are also observed for kicks perpendicular to the disk, but are weaker and develop into caustics only after a long delay (>1 year). Unless both BH spins are low or precisely aligned with the orbital angular momentum, a significant fraction (> several %) of kicks are sufficiently large and well aligned with the orbital plane for strong shocks to be produced. The shocks could result in an afterglow whose characteristic photon energy increases with time, from the UV (~10eV) to the soft X-ray (~100eV) range, between one month and one year after the merger. This could help identify EM counterparts to GW sources discovered by LISA.

Finite-Size Effects for Dyonic Giant Magnons

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We compute finite-size corrections to dyonic giant magnons in two ways. One is by examining the asymptotic behavior of helical strings of hep-th/0609026 as elliptic modulus k goes to unity, and the other is by applying the generalized Luscher formula for mu-term of arXiv:0708.2208 to the situation in which incoming particles are boundstates. By careful choice of poles in the su(2|2)^2-invariant S-matrix, we find agreement of the two results, which makes possible to predict the (leading) finite-size correction for dyonic giant magnons to all orders in the 't Hooft coupling.

description: We study the distributions functions for global partial density of states (GPDOS) in quasi-one-dimensional (Q1D) disordered wires as a function of disorder parameter from metal to insulator. We consider two different models for disordered Q1D wire: a set of two dimensional $δ$ potentials with an arbitrary signs and strengths placed randomly, and a tight-binding Hamiltonian with several modes and on-site disorder. The Green functions (GF) for two models were calculated analytically and it was shown that the poles of GF can be presented as determinant of the rank $N\times N$, where $N$ is the number of scatters. We show that the variances of partial GPDOS in the metal to insulator crossover regime are crossing. The critical value of disorder $w_c$ where we have crossover can be used for calculation a localization length in Q1D systems.

The functional-integral approach to Gaussian fluctuations in Eliashberg theory

Publisher: name: arXiv
Year: 2020
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The Eliashberg theory of superconductivity is based on a dynamical electron-phonon interaction as opposed to a static interaction present in BCS theory. The standard derivation of Eliashberg theory is based on an equation of motion approach, which incorporates certain approximations such as Migdal's approximation for the pairing vertex. In this paper we provide a functional-integral-based derivation of Eliashberg theory and we also consider its Gaussian-fluctuation extension. The functional approach enables a self-consistent method of computing the mean-field equations, which arise as saddle-point conditions, and here we observe that the conventional Eliashberg self energy and pairing function both appear as Hubbard-Stratonovich transformations. An important consequence of this fact is that it provides a systematic derivation of the Cooper and density-channel interactions in the Gaussian fluctuation response. We also investigate the strong-coupling fluctuation diamagnetic susceptibility near the critical temperature.

"Invasion" of the "Immigrant Hordes" : an analysis of current arguments in Canada against multiculturalism and immigration policy
Creators: name: Puttagunta, P. Saradhi
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a study of the current backlash against immigration and multiculturalism policies. The author looks at current arguments against both policies, and compares them to evidence. These arguments are drawn from the media; the writings of critics like Richard Gwyn, and William D. Gairdner; and the policies of the Reform Party. It will provide a historical review of the experiences of immigrant groups in adapting to Canadian society. From this review, the author identifies several consistent themes in anti-multiculturalism and anti-immigration literature, which include: multiculturalism is little more than "flash and dance", the policy is unanimously unpopular among the general public, immigrants take jobs from Canadian-born, immigrants are a burden to society, and that immigrants are not needed to offset the ageing of the Canadian population. The author concludes that these criticisms are based on misconceptions and distortions of facts. In some cases, the criticisms reflect more of an attack on minority groups rather than on these policies, and reveal a movement to reverse the pluralistic nature of Canadian society. This research comes at a time when the debate over these policies is clouded with emotion. The author makes several recommendations as to how the public education system can help counter the use of these themes in the media.

Dynamical polarization of graphene at finite doping

description: The polarization of graphene is calculated exactly within the random phase approximation for arbitrary frequency, wave vector, and doping. At finite doping, the static susceptibility saturates to a constant value for low momenta. At $q=2 k_{F}$ it has a discontinuity only in the second derivative. In the presence of a charged impurity this results in Friedel oscillations which decay with the same power law as the Thomas Fermi contribution, the latter being always dominant. The spin density oscillations in the presence of a magnetic impurity are also calculated. The dynamical polarization for low $q$ and arbitrary $ω$ is employed to calculate the dispersion relation and the decay rate of plasmons and acoustic phonons as a function of doping. The low screening of graphene, combined with the absence of a gap, leads to a significant stiffening of the longitudinal acoustic lattice vibrations.

description: We discuss propagation effects in realistic, transparent, metallo-dielectric photonic band gap structures in the context of negative refraction and super-resolution in the visible and near infrared ranges. In the resonance tunneling regime, we find that for transverse-magnetic incident polarization, field localization effects contribute to a waveguiding phenomenon that makes it possible for the light to remain confined within a small fraction of a wavelength, without any transverse boundaries, due to the suppression of diffraction. This effect is related to negative refraction of the Poynting vector inside each metal layer, balanced by normal refraction inside the adjacent dielectric layer: The degree of field localization and material dispersion together determine the total momentum that resides within any given layer, and thus the direction of energy flow. We find that the transport of evanescent wave vectors is mediated by the excitation of quasi-stationary, low group velocity surface waves responsible for relatively large losses. As representative examples we consider transparent metallo-dielectric stacks such as Ag/TiO2 and Ag/GaP and show in detail how to obtain the optimum conditions for high transmittance of both propagating and evanescent modes for super-guiding and super resolution applications across the visible and near IR ranges. Finally, we study the influence of gain on super-resolution. We find that the introduction of gain can compensate the losses caused by the excitation of surface plasmons, improves the resolving characteristics of the lens, and leads to gain-tunable super-resolution.

Using the gravity dual of this system, we study chiral phase transition at finite chemical potential and temperature and find a line of first order phase transitions in the phase plane. We compute the spectral function and the photon emission rate. The trace of the spectral function is monotonic at vanishing chemical potential, but develops some interesting features as the value of the chemical potential is increased.

description: Summer 2020 has been marked by a series of massive changes in people’s travelling and vacation habits as a consequence of SARS-CoV-2 pandemic: Italy’s detached, “disconnected”, “hidden” areas seem to be now on the map of tourist destinations . Not only “common people” but also many VIPs have “deserted” the usual routes and the “party circuits” to turn to more “peripherical” choices. “Peripheries” as tourist destinations are definitely a staple of summer 2020: new vacation trends are rising and, in this quest for the “safe periphery”, an interest for the “third landscape” (Clément 2004) is clearly involved. The “third landscape” is an “unattended space” where biological diversity thrives, an “undetermined area”, “the genetic resevoir of the planet, the space of the future”, in the words of Clément himself. The “third landscape” is, from this perspective, a complex territory that can be in many ways articulated as a tourist destination. One of the most conspicuous trends seems to be the rising curiosity for neglected spaces such as old castles, abandoned villas and churches, severed graveyards, forsaken leisure spaces such as discos, theatres and cinemas.The contemporary tourist is a bit like a postmodern explorer, following those teams of urban explorers (urbexers) that are more and more active all over the world.. Urbexers engage in exploring and recording abandoned places and buildings, not “structured” and “pinned” in mainstream touristic routes. The aim of this paper is to analyze these emerging forms of tourism and their potential developments in a dramatically altered, and constantly changing, world scenario.

description: Chemically peculiar stars define a class of stars that show unusual elemental abundances due to stellar photospheric effects and not due to natal variations. In this paper, we compare the elemental abundance patterns of the ultra metal-poor stars with metallicities [Fe/H] $\sim -5 $ to those of a subclass of chemically peculiar stars. These include post-AGB stars, RV Tauri variable stars, and the Lambda Bootis stars, which range in mass, age, binarity, and evolutionary status, yet can have iron abundance determinations as low as [Fe/H] $\sim -5$. These chemical peculiarities are interpreted as due to the separation of gas and dust beyond the stellar surface, followed by the accretion of dust depleted-gas. Contrary to this, the elemental abundances in the ultra metal-poor stars are thought to represent yields of the most metal-poor supernova and, therefore, observationally constrain the earliest stages of chemical evolution in the Universe. The abundance of the elements in the photospheres of the ultra metal-poor stars appear to be related to the condensation temperature of that element; if so, then their CNO abundances suggest true metallicities of [X/H]~ -2 to -4, rather than their present metallicities of [Fe/H] < -5.

description: The generation of a tsunami wave by an aerial landslide is investigated through model laboratory experiments. We examine the collapse of an initially dry column of grains into a shallow water layer and the subsequent generation of waves. The experiments show that the collective entry of the granular material into water governs the wave generation process. We observe that the amplitude of the wave relative to the water height scales linearly with the Froude number based on the horizontal velocity of the moving granular front relative to the wave velocity. For all the different parameters considered here, the aspect ratio and the volume of the column, the diameter and density of the grains, and the height of the water, the granular collapse acts like a moving piston displacing the water. We also highlight that the density of the falling grains has a negligible influence on the wave amplitude, which suggests that the volume of grains entering the water is the relevant parameter in the wave generation.

description: With entanglement-assisted (EA) formalism, arbitrary classical linear codes are allowed to transform into EAQECCs by using pre-shared entanglement between the sender and the receiver. In this paper, based on classical cyclic MDS codes by exploiting pre-shared maximally entangled states, we construct two families of $q$-ary entanglement-assisted quantum MDS codes $[[\frac{q^{2}+1}{a},\frac{q^{2}+1}{a}-2(d-1)+c,d;c]]$, where q is a prime power in the form of $am+l$, and $a=(l^2+1)$ or $a=\frac{(l^2+1)}{5}$. We show that all of $q$-ary EAQMDS have minimum distance upper limit much larger than the known quantum MDS (QMDS) codes of the same length. Most of these $q$-ary EAQMDS codes are new in the sense that their parameters are not covered by the codes available in the literature.

description: Στην παρούσα εργασία γίνεται καταγραφή της λειτουργίας Αντιρατσιστικής Πρωτοβουλίας Θεσσαλονίκης (ΑΠΘ) και της «ομπρέλας» της (συνιστώσες της) και χρησιμοποιείται η Κριτική Ανάλυση Λόγου ως μεθοδολογικό εργαλείο για τον γραπτό λόγο της οργάνωσης κατά την πρώτη δεκαετία δράσης της (1998-2007). Η ΑΠΘ είναι μια οργάνωση με αριστερό προσανατολισμό και ο λόγος της εντάσσεται στα πλαίσια του λόγου της Αλληλεγγύης. Πρόκειται για ένα λόγο εναλλακτικό, αντίβαρο στους κυρίαρχους λόγους των ελίτ που αμφισβητεί το status quo και προτρέπει για δράση λειτουργώντας ως αντι-εξουσία (counter-power). Με δεδομένο πως η γλώσσα δεν είναι ουδέτερη εξετάζονται: το λεξιλόγιο, οι στρατηγικές λόγου και οι ρητορικές δομές των κειμένων. Στο λόγο της αναδύεται το τριπλό σχήμα «καλοί, κακοί και άσχημοι» που αντιστοιχεί στα ακόλουθα κοινωνικά υποκείμενα: α) τους αλληλέγγυους-συμπαραστάτες, β) τους ρατσιστές και τον κρατικό μηχανισμό με τις δυνάμεις καταστολής και γ) τις εν θέσει και εν δυνάμει κοινωνικά αποκλεισμένες ομάδες (κυρίως μετανάστες και των πρόσφυγες). Υπάρχει πολωτική παρουσίαση των «καλών» και των «κακών» και διαβάθμιση ενεργητικότητας μεταξύ των τριών κοινωνικών συντελεστών. Η παρουσίαση των άσχημων είναι η πιο ποικιλόμορφη, ανάλογα με το αναγνωστικό κοινό και τους στόχους που επιθυμεί να πετύχει η οργάνωση.
description: In this thesis there is description of the function of Antiracist Initiative of Thessaloniki and its ‘umbrella’ (relative organizations, groups etc). Texts of the first decade of the organization have been researched using the methodological tool of Critical Discourse Analysis. Antiracist Initiative of Thessaloniki is a left wing organization and its discourse can be labeled as ‘Solidarity Discourse’. It is an alternative discourse, against mainstream discourses of elites which questions ‘status quo’ and urge people to act, therefore Antiracist Initiative Discourse can be described as counter-power discourse. Given that language not neutral: lexicon, discourse strategies and rhetorical structures are examined. There is a triple emerging scheme: the ‘good’, the ‘bad’ and the ‘ugly’ which corresponds to the following social actors: a) members of solidarity movements b) racists and state and c) social excluded groups (mainly immigrants and refugees). There is a polarizing presentation of the ‘good’ and the ‘bad’ and gradation of agency of the three social actors. The ‘ugly’ are depicted in a variety of ways according to the audience it addresses and the targets the organization wishes to fulfill.
Why Y chromosome is shorter and women live longer?

description: We have used the Penna ageing model to analyze how the differences in evolution of sex chromosomes depend on the strategy of reproduction. In panmictic populations, when females (XX) can freely choose the male partner (XY) for reproduction from the whole population, the Y chromosome accumulates defects and eventually the only information it brings is a male sex determination. As a result of shrinking Y chromosome the males become hemizygous in respect to the X chromosome content and are characterized by higher mortality, observed also in the human populations. If it is assumed in the model that the presence of the male is indispensable at least during the pregnancy of his female partner and he cannot be seduced by another female at least during the one reproduction cycle - the Y chromosome preserves its content, does not shrink and the lifespan of females and males is the same. Thus, Y chromosome shrinks not because of existing in one copy, without the possibility of recombination, but because it stays under weaker selection pressure; in panmictic populations without the necessity of being faithful, a considerable fraction of males is dispensable and they can be eliminated from the population without reducing its reproduction potential.

Hausdorff measure and Hausdorff dimension in such spaces are defined, and an upper bound for the Hausdorff dimension is obtained. The relation between the Haar measure and the Hausdorff measure is clarified. Finally, we discus an example in ${Bbb R}\times{\Bbb Q}\sb 2$ and calculate upper and lower bounds for its Hausdorff dimension.

description: For data sets with similar features, for example highly correlated features, most existing stability measures behave in an undesired way: They consider features that are almost identical but have different identifiers as different features. Existing adjusted stability measures, that is, stability measures that take into account the similarities between features, have major theoretical drawbacks. We introduce new adjusted stability measures that overcome these drawbacks. We compare them to each other and to existing stability measures based on both artificial and real sets of selected features. Based on the results, we suggest using one new stability measure that considers highly similar features as exchangeable.
Biomembranes undergo complex, non-axisymmetric deformations governed by Kirchhoff-Love kinematics and revealed by a three dimensional computational framework

description: Biomembranes play a central role in various phenomena like locomotion of cells, cell-cell interactions, packaging of nutrients, and in maintaining organelle morphology and functionality. During these processes, the membranes undergo significant morphological changes through deformation, scission, and fusion. Modeling the underlying mechanics of such morphological changes has traditionally relied on reduced order axisymmetric representations of membrane geometry and deformation. Axisymmetric representations, while robust and extensively deployed, suffer from their inability to model symmetry breaking deformations and structural bifurcations. To address this limitation, a 3D computational mechanics framework for high fidelity modeling of biomembrane deformation is presented. The proposed framework brings together Kirchhoff-Love thin-shell kinematics, Helfrich-energy based mechanics, and state-of-the-art numerical techniques for modeling deformation of surface geometries. Lipid bilayers are represented as spline-based surfaces immersed in a 3D space; this enables modeling of a wide spectrum of membrane geometries, boundary conditions, and deformations that are physically admissible in a 3D space. The mathematical basis of the framework and its numerical machinery are presented, and their utility is demonstrated by modeling 3 classical, yet non-trivial, membrane problems: formation of tubular shapes and their lateral constriction, Piezo1-induced membrane footprint generation and gating response, and the budding of membranes by protein coats during endocytosis. For each problem, the full 3D membrane deformation is captured, potential symmetry-breaking deformation paths identified, and various case studies of boundary and load conditions are presented. Using the endocytic vesicle budding as a case study, we also present a "phase diagram" for its symmetric and broken-symmetry states.
