description: A theory of electromagnetic wave propagation in a weakly anisotropic smoothly inhomogeneous medium is developed, based on the quantum-mechanical diagonalization procedure applied to Maxwell equations. The equations of motion for the translational (ray) and intrinsic (polarization) degrees of freedom are derived ab initio. The ray equations take into account the optical Magnus effect (spin Hall effect of photons) as well as trajectory variations owing to the medium anisotropy. Polarization evolution is described by the precession equation for the Stokes vector. In generic case, the evolution of waves turns out to be non-Abelian: it is accompanied by mutual conversion of the normal modes and periodic oscillations of the ray trajectories analogous to electron zitterbewegung. The general theory is applied to examples of wave evolution in media with circular and linear birefringence.

Do anomalies break the momentum routing invariance?

description: The diagrammatic computation of anomalies is usually associated with the breaking of the momentum routing invariance. This is because the momentum routing is usually chosen to fulfill the desired Ward identity. In the case of the chiral anomaly, the momentum routing is chosen in order to fulfill the gauge Ward identity and break the chiral Ward identity. Although the chiral anomaly is physical because it is associated with the pion decay into two photons, this does not necessarily mean that the momentum routing invariance is broken because the momentum routing was chosen in the computation of the anomaly. The reciprocal is not true, {\it i. e.} anomalies do not imply in momentum routing invariance breaking. In this work, we show that if gauge invariance is assumed, the chiral and the scale anomalies are independent of the momentum routing chosen and as a result they are momentum routing invariant. This idea is applied to a QED with non-minimal CPT and Lorentz violation, where momentum routing invariance is used to find out what symmetry is broken in the Ward identities.

description: We have obtained high resolution spectrograms of small scale magnetic structures with the Swedish 1-m Solar Telescope. We present Doppler measurements at $0\farcs{2}$ spatial resolution of bright points, ribbons and flowers and their immediate surroundings, in the C {\small{I}} 5380.3 Å line (formed in the deep photosphere) and the two Fe {\small{I}} lines at 5379.6 Å and 5386.3 Å. The velocity inside the flowers and ribbons are measured to be almost zero, while we observe downflows at the edges. These downflows are increasing with decreasing height. We also analyze realistic magneto-convective simulations to obtain a better understanding of the interpretation of the observed signal. We calculate how the Doppler signal depends on the velocity field in various structures. Both the smearing effect of the non-negligible width of this velocity response function along the line of sight and of the smearing from the telescope and atmospheric point spread function are discussed. These studies lead us to the conclusion that the velocity inside the magnetic elements are really upflow of the order 1--2 km s${}^{-1}$ while the downflows at the edges really are much stronger than observed, of the order 1.5--3.3 km s${}^{-1}$.

description: Interest in stealth coronal mass ejections (CMEs) is increasing due to their relatively high occurrence rate and space weather impact. However, typical CME signatures such as extreme-ultraviolet dimmings and post-eruptive arcades are hard to identify and require extensive image processing techniques. These weak observational signatures mean that little is currently understood about the physics of these events. We present an extensive study of the magnetic field configuration in which the stealth CME of 3 March 2011 occurred. Three distinct episodes of flare ribbon formation are observed in the stealth CME source active region (AR). Two occurred prior to the eruption and suggest the occurrence of magnetic reconnection that builds the structure which will become eruptive. The third occurs in a time close to the eruption of a cavity that is observed in STEREO-B 171A data; this subsequently becomes part of the propagating CME observed in coronagraph data. We use both local (Cartesian) and global (spherical) models of the coronal magnetic field, which are complemented and verified by the observational analysis. We find evidence of a coronal null point, with field lines computed from its neighbourhood connecting the stealth CME source region to two ARs in the northern hemisphere. We conclude that reconnection at the null point aids the eruption of the stealth CME by removing field that acted to stabilise the pre-eruptive structure. This stealth CME, despite its weak signatures, has the main characteristics of other CMEs, and its eruption is driven by similar mechanisms.

description: Using e+e- -> mu+mu-(gamma) and e+e- -> qqbar(gamma) events radiative to the Z pole, DELPHI has determined the centre-of-mass energy, sqrt{s}, using energy and momentum constraint methods. The results are expressed as deviations from the nominal LEP centre-of-mass energy, measured using other techniques. The results are found to be compatible with the LEP Energy Working Group estimates for a combination of the 1997 to 2000 data sets.

description: This work presents an asymmetric dark matter model with relic density determined by the freeze-out of asymmetric semi-annihilations into long-lived particles slowly decaying into the Standard Model states. We carefully consider the $CPT$ symmetry and unitarity constraints to the asymmetries entering the Boltzmann equation. The main idea of the paper is to point out a critical inconsistency in the previous literature, where these constraints are violated. We present a systematic approach to avoid the inconsistency.

description: Low-energy cosmic rays (LECRs) contribute substantially to the energy balance of the interstellar medium. They play also significant role in the heating and chemistry of gas, and, consequently, on the star formation process. Because of the slow propagation coupled with enhanced energy losses of subrelativistic particles, LECRs are concentrated around their acceleration sites. LECRs effectively interact with the ambient gas through nuclear reactions. Although these processes are energetically less effective compared to heating and ionization, they are extremely important from the point of view of nuclear de-excitation lines, which carry unique information about LECRs. We present results on production of de-excitation lines combining the numerical treatment of nuclear reactions using the code TALYS, with the propagation and energy losses of LECRs.

description: This research paper presents a groundbreaking perspective on gravity, proposing that it is not a separate force arising from the curvature of space-time, as traditionally believed, but instead originates from atomic nuclei. By examining the role of atomic nuclei, this study redefines gravity as a positive charge force that exhibits weak attraction to neutral atoms and a repulsive force against similarly charged atoms.

In this work, we argue that conventional theories of gravity, including those proposed by Newton and Einstein, face limitations when applied to quantum scales and certain cosmic phenomena. This paper addresses these gaps by offering a practical and detailed explanation of how gravitational forces operate within our solar system, galaxies, and the broader universe.

The research integrates principles from quantum mechanics with gravitational theories, providing a cohesive framework that reconciles existing theoretical inconsistencies. By exploring the interactions of atomic nuclei, this paper sheds light on key cosmological challenges and proposes a unified model that encompasses both microscopic and macroscopic scales.

description: We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin films of Co$_{0.975}$Ge$_{0.025}$Cr$_2$O$_4$ (Ge-CCO) and CoCr$_2$O$_4$ (CCO), under low- and high-magnetic fields, from 0.2 T up to 6.5 T. A characterization of Ge-CCO at a low magnetic field is performed and the results are compared to those of pure CCO. The ferrimagnetic phase transition temperature $T_C \approx 95$ K and the multiferroic transition temperature $T_S \approx 27$ K in Ge-CCO are comparable to those observed in CCO. In Ge-CCO, the ordering wave vector $\textit{(qq0)}$ observed below $T_S$ is slightly larger compared to that of CCO, and, unlike CCO, the diffraction intensity consists of two contributions that show a dissimilar x-ray polarization dependence. In Ge-CCO, the coercive field observed at low temperatures was larger than the one reported for CCO. In both compounds, an unexpected reversal of the spiral helicity and therefore the electric polarization was observed on simply magnetic field cooling. In addition, we find a change in the helicity as a function of momentum transfer in the magnetic diffraction peak of Ge-CCO, indicative of the presence of multiple magnetic spirals.

description: Coherent optical information storage capacity of an atomic Bose-Einstein condensate is examined. Theory of slow light propagation in atomic clouds is generalized to short pulse regime by taking into account group velocity dispersion. It is shown that the number of stored pulses in the condensate can be optimized for a particular coupling laser power, temperature and interatomic interaction strength. Analytical results are derived for semi-ideal model of the condensate using effective uniform density zone approximation. Detailed numerical simulations are also performed. It is found that axial density profile of the condensate protects the pulse against the group velocity dispersion. Furthermore, taking into account finite radial size of the condensate, multi-mode light propagation in atomic Bose-Einstein condensate is investigated. The number of modes that can be supported by a condensate is found. Single mode condition is determined as a function of experimentally accessible parameters including trap size, temperature, condensate number density and scattering length. Quantum coherent atom-light interaction schemes are proposed for enhancing multi-mode light propagation effects.

description: Context. JavaScript is a popular programming language today with several implementations competing for market dominance. Although a specification document and a conformance test suite exist to guide engine development, bugs occur and have important practical consequences. Implementing correct engines is challenging because the spec is intentionally incomplete and evolves frequently. Objective. This paper investigates the use of test transplantation and differential testing for revealing functional bugs in JavaScript engines. The former technique runs the regression test suite of a given engine on another engine. The latter technique fuzzes existing inputs and then compares the output produced by different engines with a differential oracle. Method. We conducted experiments with engines from five major players-Apple, Facebook, Google, Microsoft, and Mozilla-to assess the effectiveness of test transplantation and differential testing. Results. Our results indicate that both techniques revealed several bugs, many of which confirmed by developers. We reported 35 bugs with test transplantation (23 of these bugs confirmed and 19 fixed) and reported 24 bugs with differential testing (17 of these confirmed and 10 fixed). Results indicate that most of these bugs affected two engines-Apple's JSC and Microsoft's ChakraCore (24 and 26 bugs, respectively). To summarize, our results show that test transplantation and differential testing are easy to apply and very effective in finding bugs in complex software, such as JavaScript engines.

description: The arrow of time dilemma: the laws of physics are invariant for time inversion, whereas the familiar phenomena we see everyday are not (i.e. entropy increases). I show that, within a quantum mechanical framework, all phenomena which leave a trail of information behind (and hence can be studied by physics) are those where entropy necessarily increases or remains constant. All phenomena where the entropy decreases must not leave any information of their having happened. This situation is completely indistinguishable from their not having happened at all. In the light of this observation, the second law of thermodynamics is reduced to a mere tautology: physics cannot study those processes where entropy has decreased, even if they were commonplace.

description: This paper presents a cooperative dynamic task assignment framework for a certain class of Autonomous Underwater Vehicles (AUVs) employed to control outbreak of Crown-Of-Thorns Starfish (COTS) in Australia's Great Barrier Reef. The problem of monitoring and controlling the COTS is transcribed into a constrained task assignment problem in which eradicating clusters of COTS, by the injection system of COTSbot AUVs, is considered as a task. A probabilistic map of the operating environment including seabed terrain, clusters of COTS, and coastlines is constructed. Then, a novel heuristic algorithm called Heuristic Fleet Cooperation (HFC) is developed to provide a cooperative injection of the COTSbot AUVs to the maximum possible COTS in an assigned mission time. Extensive simulation studies together with quantitative performance analysis are conducted to demonstrate the effectiveness and robustness of the proposed cooperative task assignment algorithm in eradicating the COTS in the Great Barrier Reef.

description: We propose a nonadiabatic non-Abelian geometric quantum operation scheme to realize universal quantum computation with mesoscopic Rydberg atoms. A single control atom entangles a mesoscopic ensemble of target atoms through long-range interactions between Rydberg states. We demonstrate theoretically that both the single qubit and two-qubit quantum gates can achieve high fidelities around or above 99.9% in ideal situations. Besides, to address the experimental issue of Rabi frequency fluctuation (Rabi error) in Rydberg atom and ensemble, we apply the dynamical-invariant-based zero systematic-error sensitivity (ZSS) optimal control theory to the proposed scheme. Our numerical simulations show that the average fidelity could be 99.98% for single ensemble qubit gate and 99.94% for two-qubit gate even when the Rabi frequency of the gate laser acquires 10% fluctuations. We also find that the optimized scheme can also reduce errors caused by higher-order perturbation terms in deriving the Hamiltonian of the ensemble atoms. To address the experimental issue of decoherence error between the ground state and Rydberg levels in Rydberg ensemble, we introduce a dispersive coupling regime between Rydberg and ground levels, based on which the Rydberg state is adiabatically discarded. The numerical simulation demonstrate that the quantum gate is enhanced. By combining strong Rydberg atom interactions, nonadiabatic geometric quantum computation, dynamical invariant and optimal control theory together, our scheme shows a new route to construct fast and robust quantum gates with mesoscopic atomic ensembles. Our study contributes to the ongoing effort in developing quantum information processing with Rydberg atoms trapped in optical lattices or tweezer arrays.

description: We present a detailed optical study of single crystal bismuth using infrared reflectivity and ellipsometry. Colossal changes in the plasmon frequency are observed as a function of temperature due to charge transfer between hole and electron Fermi pockets. In the optical conductivity, an anomalous temperature dependent mid-infrared absorption feature is observed. An extended Drude model analysis reveals that it can be connected to a sharp upturn in the scattering rate, the frequency of which exactly tracks the temperature dependent plasmon frequency. We interpret this absorption and increased scattering as the first direct optical evidence for a charge carrier interaction with a collective mode of purely electronic origin; here electron-plasmon scattering. The observation of a \emph{plasmaron} as such is made possible only by the unique coincidence of various energy scales and exceptional properties of semi-metal bismuth.

description: Η παρούσα εργασία εξετάζει το υπερκείμενο (hypertext) από τη σκοπιά των λογοτεχνικών σπουδών και επιχειρεί να ανιχνεύσει τις συνέπειές του στην ανάγνωση της λογοτεχνίας και στην πρακτική των φιλολογικών εκδόσεων, αλλά και να διερευνήσει τις προοπτικές εφαρμογής του στη λογοτεχνική εκπαίδευση. Αρχικά (1ο Κεφάλαιο), επισημαίνονται οι κυριότεροι σταθμοί στην ιστορία του υπερκειμένου ως έννοιας και ως τεχνολογικού εργαλείου και διερευνώνται τα όριά του ως όρου, καθώς και η σχέση του με συναφείς όρους από το πεδίο της ψηφιακής κειμενικότητας. Στη συνέχεια (2ο Κεφάλαιο), αναλύεται η επιχειρηματολογία των πρώτων θεωρητικών του υπερκειμένου για την απελευθερωτική του αξία, καθώς και η κριτική που τους ασκήθηκε από μεταγενέστερους κριτικούς, σε μια προσπάθεια να οριστούν οι βασικές παράμετροι που προσδιορίζουν την αισθητική και τη λειτουργικότητα του υπερκειμένου. Έπειτα (3ο Κεφάλαιο), εξετάζεται η χρησιμότητα του υπερκειμένου ως εργαλείου παρουσίασης έντυπων λογοτεχνικών κειμένων και ανιχνεύεται η μεθοδολογία και οι πρακτικές που έχουν αναπτυχθεί μέσα από τρία ενδεικτικά παραδείγματα ψηφιακών αρχείων. Τέλος (4ο κεφάλαιο), σημειώνονται οι προβληματισμοί που συνοδεύουν τις προσπάθειες εφαρμογής του στη λογοτεχνική εκπαίδευση και αναζητώνται οι προϋποθέσεις εισαγωγής του ως διδακτικού εργαλείου μέσα από τον σχεδιασμό μια υπερκειμενικής εφαρμογής για τη δευτεροβάθμια εκπαίδευση που αφορά το ποιητικό σύνθεμα του Σολωμού «Ελεύθεροι Πολιορκημένοι» (Επίμετρο).
description: The current dissertation discusses hypertext from the perspective of literary studies and attempts to detect its impact on literature reading and the practices of literary editions as well as research the prospects of its application to literary education. First (1st Chapter), the most important milestones in the history of hypertext as a concept and as a technology tool are underlined and its limitations as a term as well as its relation to relevant terms within the field of digital textuality are explored. Second (2nd Chapter), the first theorists’ argumentation regarding the liberating value of hypertext and the criticism expressed towards their views by later theorists are analysed in an attempt to define the basic parameters which determine hypertext aesthetics and functionality. Then (3rd Chapter) the usefulness of hypertext as a presentation tool for printed literary texts is assessed whereas methodology and practices that have been developed are examined by means of three representative examples of digital archives. Finally (4th Chapter), the concerns resulting from its implementation in literary education are recorded and the prerequisites for introducing hypertext as a teaching tool in secondary education are sought by designing a hypertext application for secondary education regarding the poetic composition by Dionysios Solomos "Eleftheroi Poliorkimenoi."

description: We consider a 5D BPS dilatonic two brane model which reduces to the Randall-Sundrum model or the Horava-Witten theory for a particular choice of parameters. Recently new dynamical solutions were found by Chen et al., which describe a moduli instability of the warped geometry. Using a 4D effective theory derived by solving the 5D equations of motion, based on the gradient expansion method, we show that the exact solution of Chen et. al. can be reproduced within the 4D effective theory and we identify the origin of the moduli instability. We revisit the gradient expansion method with a new metric ansatz to clarify why the 4D effective theory solution can be lifted back to an exact 5D solution. Finally we argue against a recent claim that the 4D effective theory allows a much wider class of solutions than the 5D theory and provide a way to lift solutions in the 4D effective theory to 5D solutions perturbatively in terms of small velocities of the branes.

Εξετάσαμε το συνταγματικό θεμέλιο του δικηγορικού απορρήτου, τις επιμέρους διατάξεις που το προστατεύουν και το προστατευόμενο με αυτό έννομο αγαθό. Στη συνέχεια παρουσιάσαμε αναλυτικά τα στοιχεία της αντικειμενικής και υποκειμενικής υπόστασης του εγκλήματος, τους λόγους άρσης του άδικου χαρακτήρα της πράξης της φανέρωσης του απορρήτου, καθώς και επιμέρους ζητήματα απόπειρας, συμμετοχής, συρροής, απειλούμενης ποινής και τρόπου άσκησης της ποινικής δίωξης. Ακόμη αναφερθήκαμε αναλυτικά στα αντίστοιχα άρθρα της ποινικής δικονομίας, τα οποία συμπληρώνουν την εν λόγω προστασία, καθώς και σε σκέψεις αναφορικά με την ανάγκη για τροποποίηση ορισμένων ασαφειών του νόμου.
description: The aim of the present thesis was the protection from violation of professional secrets by lawyers in Greek Criminal Law. We examined the constitutional basis of such protection, the articles of law that establish such protection and the related legal good. Then we presented the features of this criminal offence, mens rea and questions of law, such as attempt, complicity, appearing conjunction of offences, punishment and criminal prosecution. Furthermore, we analyzed the criminal procedure that prevents from violation of professional secrets and problems such as vague provision of law.

description: Τα αυτόματα δέντρων εφαρμόστηκαν κυρίως στο automated reasoning για πεπερασμένα συστήματα. Μολονότι η χρήση αυτών των αυτομάτων είναι πολύ σημαντική, τα τελευταία χρόνια δημιουργήθηκε η ανάγκη για δημιουργία νέων μοντέλων που ορίζονται πάνω σε άπειρα αλφάβητα. Η χρήση και η επέκταση της XML όπως και η χρήση δέντρων σε άπειρα δεδομένα (data trees) αποτελούν χαρακτηριστικά παραδείγματα. Στην παρούσα διπλωματική εργασία εισάγεται ένα νέο αυτόματο σε άπειρα αλφάβητα, το variable tree automaton, του οποίου η λειτουργία στηρίζεται σε ένα πεπερασμένο bottom-up tree automaton. Στη συνέχεια, ορίζεται η κλάση αναγνωρίσιμων γλωσσών από variable tree automata (variable recognizable languages - VREC), η οποία αποδεικνύεται ότι είναι κλειστή ως προς τις πράξεις της ένωσης και της τομής, αλλά όχι του συμπληρώματος, και εξετάζονται τα σημαντικότερα προβλήματα απόφασης σε αυτήν την κλάση. Αποδεικνύεται ότι μπορούμε να αποφασίσουμε αν μία γλώσσα είναι κενή ή πεπερασμένη, ενώ το πρόβλημα της ισοδυναμίας δύο γλωσσών και της καθολικότητας είναι αποφασίσιμα υπό περιορισμούς. Τέλος, παρουσιάζεται η σύνδεση του variable tree automaton με το αντίστοιχο μοντέλο σε λέξεις.
description: We consider variable tree automata with infinite input ranked alphabets, a model based on an underlying tree automaton that runs over a finite ranked alphabet containing variable symbols. The underlying tree automaton computes its tree language, and then replaces the variable symbols with symbols from the infinite alphabet following certain rules. We show that the class of recognizable tree languages over infinite ranked alphabets is closed under union and intersection but not under complementation. Moreover we show that the emptiness problem is decidable, and the equivalence and universality problems are decidable within special subclasses of variable tree automata.

description: Κεντρικός στόχος της παρούσας εργασίας είναι να εξεταστεί η παραβατική συμπεριφορά του εκπαιδευτικού καθώς και οι διάφορες εκφάνσεις που αυτή φανερώνεται στην σχολική πραγματικότητα. Εξετάσαμε την παιδαγωγική σχέση μεταξύ εκπαιδευτικού και μαθητή, τη δομή της σχολικής τάξης ως ομάδας, τα προβλήματα που προκύπτουν στη σχολική τάξη μεταξύ των εκπαιδευτικών και των μαθητών καθώς και τις μορφές παραβατικής συμπεριφοράς του εκπαιδευτικού. Στη συνέχεια κάναμε μια ιστορική αναδρομή από την αρχαιότητα μέχρι τον ευρωπαϊκό διαφωτισμό για να διαπιστωθεί, εάν η σύγχρονη παραβατικότητα του εκπαιδευτικού σχετίζεται με παραβατικές συμπεριφορές που χρησιμοποιήθηκαν στην εκπαίδευση σε διαχρονικό επίπεδο. Τέλος, επιδιώξαμε να διερευνήσουμε τις μεθόδους που χρησιμοποιεί ο εκπαιδευτικός, αν δηλαδή διαμορφώνει προϋποθέσεις διαλόγου, συνεργασίας και συμμετοχής του μαθητή στις σχολικές διαδικασίες, αν χρησιμοποιεί ορθολογική επιχειρηματολογία για να πείσει το μαθητή ή αν επιβάλλει τη θέλησή του μέσα από τη θεσμική και εκπαιδευτική εξουσία που διαθέτει και συνεπώς αξιώνει από το μαθητή συμμόρφωση προς τις εντολές του και ταυτόχρονα χρησιμοποιεί ως μέσα τις κυρώσεις. Επιπλέον αναζητήσαμε τα αίτια που οδηγούν τον εκπαιδευτικό σε μια τέτοια παραβατική συμπεριφορά και οι επιπτώσεις που έχει στη ψυχολογία του μαθητή.
description: The central aim of this paper is to examine the delinquent behavior of teachers and the various forms it is manifested in the school reality. We examined the educational relationship between teacher and pupil, the structure of the classroom as a group, problems arise in the classroom between teachers and students as well as forms of delinquent behavior of the teacher. Then we have a history from antiquity to the European enlightenment to determine if the current delinquency of education associated with delinquent behaviors used in education timeless level. Finally, we sought to investigate the methods used by the teacher, if we formulate conditions for dialogue, cooperation and participation of students in school procedures if using rational arguments to convince the student or impose their will through the institutional and educational power features and therefore requires the student to comply with their orders and simultaneously use it as a means of sanctions. Additionally look for the causes that lead the teacher in such delinquent behavior and the impact on the psychology student.

description: We present recent preliminary measurements of the top-antitop pair production cross section and determinations of the top quark pole mass, performed using the data collected by the CDF and D0 Collaborations at the Tevatron Collider. In the lepton plus jets final state, with semileptonic B decay, the pair production cross section has now been measured at CDF using 760 pb^{-1} of proton-antiproton collisions at a centre-of-mass energy of \sqrt{s}=1.96 TeV. A measurement of the production cross section has also been made with 1 fb^{-1} of data in the all-jets final state by the CDF Collaboration. The mass of the top quark has now been measured using 1 fb^{-1} of collision data using all decay channels of the top quark pair, yielding the most precise measurements of the top mass to date.
