description: Meteoesce nel 1996: è una silloge poetica di Andrea Zanzotto, i cui caratteri sono quelli della frammentarietà, della provvisorietà, dell’ibridazione. L’obiettivo è dare forma, nello spazio dei versi, alla rappresentazione di un mondo devastato, che evoca gli oggetti e i luoghi dell’infanzia per capovolgerne la valenza, che annulla il tempo storico e cronologico, attraverso una lingua che è a sua volta scomposta, e violata nelle norme grammaticali e sintattiche. Meteois published in 1996: it is a book of poetry by Andrea Zanzotto, whose main characteristics are fragmentism, precariousness, hybridism. The aim is to give form, within the textual space of verses, to the representation of a devasted world, that evokes childhood’s objects and places in order to overturn its significance, and erases historical and chronological time, through a broken down language.

Testing Einstein's Equivalence Principle and its Cosmological Evolution from Quasar Gravitational Redshifts

description: We propose and apply a new test of Einstein's Equivalence Principle (EEP) based on the gravitational redshift induced by the central super massive black hole of quasars in the surrounding accretion disk. Specifically, we compare the observed gravitational redshift of the Fe III$λλ$2039-2113 emission line blend in quasars with the predicted values in a wide, uncharted, cosmic territory ($0 \lesssim z_{cosm}\lesssim3$). For the first time we measure, with statistical uncertainties comparable or better than those of other classical methods outside the Solar System, the ratio between the observed gravitational redshifts and the theoretical predictions in 10 independent cosmological redshift bins in the $1 \lesssim z_{cosm}\lesssim3$ range. The average of the measured over predicted gravitational redshifts ratio in this cosmological redshift interval is $\langle z^m_g/z_g^p\rangle=1.05\pm 0.06$ with scatter $0.13\pm 0.05$ showing no cosmological evolution of EEP within these limits. This method can benefit from larger samples of measurements with better S/N ratios, paving the way for high precision tests (below 1\%) of EEP on cosmological scales.

description: We present oxygen abundances of dwarfs in the young open cluster IC 4665 deduced from the OI $λ$7774 triplet lines and of dwarfs in the open cluster Pleiades derived from the [OI] $λ$6300 forbidden line. Stellar parameters and oxygen abundances were derived using the spectroscopic synthesis tool SME (Spectroscopy Made Easy). We find a dramatic increase in the upper boundary of the OI triplet abundances with decreasing temperature in the dwarfs of IC 4665, consistent with the trend found by Schuler et al. in the open clusters Pleiades and M 34, and to a less extent in the cool dwarfs of Hyades (Schuler et al. 2006a) and UMa (King & Schuler 2005). By contrast, oxygen abundances derived from the [OI] $λ$6300 forbidden line for stars in Pleiades and Hyades (Schuler et al. 2006b) are constant within the errors. Possible mechanisms that may lead a varying oxygen triplet line abundance are examined, including systematic errors in the stellar parameter determinations, the NLTE effects, surface activities and granulation. The age-related effects stellar surface activities (especially the chromospheric activities) are suggested by our analysis to blame for the large spreads of oxygen triplet line abundances.

description: The use of deep 3D point cloud models in safety-critical applications, such as autonomous driving, dictates the need to certify the robustness of these models to real-world transformations. This is technically challenging, as it requires a scalable verifier tailored to point cloud models that handles a wide range of semantic 3D transformations. In this work, we address this challenge and introduce 3DCertify, the first verifier able to certify the robustness of point cloud models. 3DCertify is based on two key insights: (i) a generic relaxation based on first-order Taylor approximations, applicable to any differentiable transformation, and (ii) a precise relaxation for global feature pooling, which is more complex than pointwise activations (e.g., ReLU or sigmoid) but commonly employed in point cloud models. We demonstrate the effectiveness of 3DCertify by performing an extensive evaluation on a wide range of 3D transformations (e.g., rotation, twisting) for both classification and part segmentation tasks. For example, we can certify robustness against rotations by $\pm$60° for 95.7% of point clouds, and our max pool relaxation increases certification by up to 15.6%.

Deuteron tensor polarization component T_20(Q^2) as a crucial test for deuteron wave functions

description: The deuteron tensor polarization component T_20(Q^2) is calculated by relativistic Hamiltonian dynamics approach. It is shown that in the range of momentum transfers available in to-day experiments, relativistic effects, meson exchange currents and the choice of nucleon electromagnetic form factors almost do not influence the value of T_20(Q^2). At the same time, this value depends strongly on the actual form of the deuteron wave function, that is on the model of NN-interaction in deuteron. So the existing data for T_20(Q^2) provide a crucial test for deuteron wave functions.

A critical incidents study of differentiation
Creators: name: Novotny, Helena Bozena
Publisher: name: University of British Columbia
Year: 2008

description: Eight couples participated in a workshop designed, to identify what events facilitate or hinder differentiation in everyday life. The couples met in three-hour weekly sessions over a period of eight weeks. The program incorporated psycho-educational and experiential components. The content was based on the key concepts of Bowen Family Systems Theory, communication skills, Transactional Analysis and Imago Therapy. During the program and from interviews, 508 incidents were collected. Flanagan's (1954) critical incident technique was used as an evaluation method. Subsequently, the total of 508 reported incidents was reduced to the six major categories. Each major category had its facilitating and hindering counterparts. Then, a definition was created for each category. The categories of "Openness & Intimacy" and "A Sense of Self" accounted for 51% of all facilitating as well as all hindering events. The results of the study were found to be both reliable and valid. The implications for the development of skill-training programs, counselling sessions and future research were outlined.

description: The present thesis discusses the incorporation of non-execution grounds of the European Arrest Warrant which are provided for in Council Framework Decision 2002/584/JHA in accordance with national legislation (Law 3251/2004). Systematically, it is structured examining mandatory grounds for non – execution (Article 11 Law 3251/2004), optional grounds for non – execution (Article 12 Law 3251/2004) and guarantees to be given by the issuing member state in particular cases (Article 13 Law 3251/2004). For each of the aforementioned reasons, a theoretical analysis is first attempted, followed by their case law treatment by the Hellenic Supreme Court for Criminal Cases (Areios Pagos), as well as the case law of the ECJ/CJEU regarding the interpretation of the corresponding provisions by Framework Decision. Subsequently, we deal with both the violation of fundamental rights and the principle of proportionality as grounds for non – execution of an EAW. Finally, the paper ends with brief conclusions focusing on the national legislator's choice to transport some of the grounds for non-execution which are provided for in the Framework Decision as optional into mandatory, the contrast of the jurisprudence of our national courts and specifically Areios Pagos with that of the ECJ /CJEU in certain points and an ever-increasing tendency to create new grounds for non – execution.

description: Even for holographic theories that obey boundary causality, the full bulk Lorentzian path integral includes metrics that violate this condition. This leads to the following puzzle: The commutator of two field theory operators at spacelike-separated points on the boundary must vanish. However, if these points are causally related in a bulk metric, then the bulk calculation of the commutator will be nonzero. It would appear that the integral over all metrics of this commutator must vanish exactly for holography to hold. This is puzzling since it must also be true if the commutator is multiplied by any other operator. Upon a careful treatment of boundary conditions in holography, we show how the bulk path integral leads to a natural resolution of this puzzle.

description: Young neutron stars (NSs) have magnetic fields $B$ in the range $10^{12}-10^{15}$ G, believed to be generated by dynamo action at birth. We argue that such a dynamo is actually too inefficient to explain the strongest of these fields. Dynamo action in the mature star is also unlikely. Instead we propose a promising new precession-driven dynamo and examine its basic properties, as well as arguing for a revised mean-field approach to NS dynamos. The precession-driven dynamo could also play a role in field generation in main-sequence stars.

description: We study the response of probe particles to weak constant driving in kinetically constrained models of glassy systems, and show that the probe's response can be non-monotonic and give rise to negative differential mobility: increasing the applied force can reduce the probe's drift velocity in the force direction. Oth er significant non-linear effects are also demonstrated, such as the enhancement with increasing force of the probe's fluctuations away from the average path, a phenomenon known in other contexts as giant diffusivity. We show that these res ults can be explained analytically by a continuous-time random walk approximatio n where there is decoupling between persistence and exchange times for local dis placements of the probe. This decoupling is due to dynamic heterogeneity in the glassy system, which also leads to bimodal distributions of probe particle disp lacements. We discuss the relevance of our results to experiments.

description: We give an overview of results and prospects of nuclear clustering studies on the grounds of the observations of interactions of light stable and radioactive nuclei with an initial energy above 1 A GeV in nuclear emulsions. Thank to the best spatial resolution and the full solid angle acceptance provided by nuclear emulsions, such an approach allows one to obtain unique and evident observations reecting cluster-like features in light nuclear structures. New results on dissociation of $^7$Be in very peripheral interactions with emulsion nuclei are presented. The importance of this research for the physics of few body nuclear systems and the related problems of nucleosynthesis is noted. The paper is illustrated with characteristic images obtained by means of a microscope equipped with a CCD camera. The discussed explorations are provided with the beams of the Synchrophasotron and Nuclotron of JINR, Dubna. Future investigations are suggested to be carried out in relativistic beams of He, Be, B, C, and N isotopes.

A phenomenological exploration of the experiences of aboriginal women who were sexually abused
Creators: name: McEvoy, Maureen
Publisher: name: University of British Columbia
Year: 2008

description: The last ten tears [sic] have witnessed an explosion of interest and research into the issue of incest and child sexual abuse. Researchers have been able to estimate prevalence, posit theories on the dynamics that lead to sexual abuse and articulate the short- and long-term impact of childhood sexual exploitation. Much of this information, however, pertains to mainstream North American society and specifically to white people. Much less attention has been paid to the aboriginal experience of incest and sexual abuse. While there may be similarities between the native and non-native experience of incest and child sexual abuse, there are a number of cultural and historical factors that may present wholesale application of existing research to native experience. The purpose of this phenomenological study was to begin to articulate the experience of native women who were sexually abused as children. Using Colaizzi's phenomenological approach, in-depth interviews were carried out with six aboriginal women who met the research criteria of having been sexually abused by a relative in childhood and being able to articulate their experience. The interview data was analyzed by scrutinizing the protocols to first develop constituent meaning units and then to formulate cogent themes shared by all the participants. A total of eight themes were extracted. The first three themes - a sense of shame and guilt, a sense of being unlovable and a yearning to make sense of their abuse experience - appear to be commonly reported in the literature regarding sexual abuse. The final five themes - sense of acute vulnerability, sense of invalidation, sense of cultural shame, sense of being shattered, and sense of reconstructing - appear to mark divergences from the experience of survivors of childhood sexual abuse in the mainstream culture and aboriginal survivors. Implications for further research are addressed and suggestions for counselling adult, native female survivors of child sexual abuse are provided.

description: Neutron diffraction and X-ray pair distribution function (XPDF) experiments were performed in order to investigate the magnetic and local crystal structures of Ba2FeSbSe5 and to compare them to the average (i.e. long-range) structural model, previously obtained by single crystal X-ray diffraction. Changes in the local crystal structure (i.e. in the second coordination sphere) are observed upon cooling from 295 K to 95 K resulting in deviations from the average (i.e. long-range) crystal structure. This work demonstrates, that these observations cannot be explained by local or long-range magnetoelastic effects involving Fe-Fe correlations. Instead, we found, that the observed differences between local and average crystal structure can be explained by Sb-5s lone pair dynamics. We also find, that below the Néel temperature (TN = 58 K), the two distinct magnetic Fe3+ sites order collinearly, such that a combination of antiparallel and parallel spin arrangements along the b-axis results. The nearest-neighbor arrangement (J1 = 6 Å) is fully antiferromagnetic, while next-nearest-neighbor interactions are ferromagnetic in nature.

description: The Wilson action for Euclidean lattice gauge theory defines a positive-definite transfer matrix that corresponds to a unitary lattice gauge theory time-evolution operator if analytically continued to real time. Hoshina, Fujii, and Kikukawa (HFK) recently pointed out that applying the Wilson action discretization to continuum real-time gauge theory does not lead to this, or any other, unitary theory and proposed an alternate real-time lattice gauge theory action that does result in a unitary real-time transfer matrix. The character expansion defining the HFK action is divergent, and in this work we apply a path integral contour deformation to obtain a convergent representation for U(1) HFK path integrals suitable for numerical Monte Carlo calculations. We also introduce a class of real-time lattice gauge theory actions based on analytic continuation of the Euclidean heat-kernel action. Similar divergent sums are involved in defining these actions, but for one action in this class this divergence takes a particularly simple form, allowing construction of a path integral contour deformation that provides absolutely convergent representations for U(1) and SU(N) real-time lattice gauge theory path integrals. We perform proof-of-principle Monte Carlo calculations of real-time U(1) and SU(3) lattice gauge theory and verify that exact results for unitary time evolution of static quark-antiquark pairs in (1 + 1)D are reproduced.

Πράγματι, οι νομοθετικές ρυθμίσεις του ν.4139/13 για τους εξαρτημένους από τις ναρκωτικές ουσίες χρήζουν περαιτέρω αναλύσεως, καθ’ ότι όπως θα παρουσιαστεί και παρακάτω, πρόκειται για ρυθμίσεις που στοχεύουν στην προώθηση της θεραπείας των εξαρτημένων δραστών αξιόποινων πράξεων και στην ουσιαστική επανένταξη τους, εξασφαλίζοντας ταυτόχρονα κοινωνική αποδοχή γι’ αυτούς. Κατά πόσο, βέβαια θα επιτευχθούν τα παραπάνω επί του πρακτέου μένει να κριθεί στην πορεία του χρόνου. Έπειτα, παρουσιάζονται οι δικονομικές αποκλίσεις των α.30-35 του ν.4139/13 σε σχέση με τον ΚΠοινΔ και ο βαθμός στον οποίο δικαιολογούνται εξαιτίας της φύσης των σχετικών υποθέσεων. Οι δικονομικές αποκλίσεις που υπάρχουν ανάμεσα στις διατάξεις των α.30-35 του ν.4139/13 και στις διατάξεις του ΚΠοινΔ είναι πλείστες και γίνεται σχετική μνεία αυτών στην εργασία, προσπαθώντας παράλληλα να εξεταστεί αν αυτές δικαιολογούνται από άποψη δικαιοπολιτική. Τέλος, στην εν λόγω εργασία γίνεται μια συγκριτική επισκόπηση των α.30-35 του ν.4139/13 για τους εξαρτημένους από τις ναρκωτικές ουσίες με τις αντίστοιχες του γερμανικού νομοθετήματος (BtMG), προκειμένου να αναδειχθούν οι κυριότερες ομοιότητες και διαφορές ανάμεσα στα δύο νομοθετήματα.

Indeed, the legislation of Law 4139/13 on drug addicted offenders needs further analysis because, as will be shown below, they are aimed at promoting the treatment of drug offenders and their effective reintegration into society, while ensuring social acceptance for them. Whether or not the above will be achieved remains to be seen over time. Moreover, the thesis analyzes the procedural divergences of a.30-35 of law 4139/13 and those of the CPP and the extent to which they are justified by the nature of the cases concerned. The procedural divergences between the provisions of a.30-35 of law 4139/13 and the provisions of the CPP are numerous and the thesis is trying to examine whether they are justified in the legal system. Finally, this work provides a comparative overview of A.30-35 of L. 4139/13 for drug addicted offenders with those of German law (BtMG), in order to highlight the main similarities and differences between the two legislations.

description: We consider a slow particle with wave function $ψ_t(\vec{x})$, moving freely in some direction. A mirror is briefly switched on around a time $T$ and its position is scanned. It is shown that the measured reflection probability then allows the determination of $|ψ_T(\vec{x})|^2$. Experimentally available atomic mirrors should make this method applicable to the center-of-mass wave function of atoms with velocities in the cm/s range.

description: We examine the propagation and flavor oscillations of neutrinos under the influence of gravitational waves (GWs) with an arbitrary polarization. We rederive the effective Hamiltonian for the system of three neutrino flavors using the perturbative approach. Then, using this result, we consider the evolution of neutrino flavors in stochastic GWs with a general energy density spectrum. The equation for the density matrix is obtained and solved analytically in the case of three neutrino flavors. As an application, we study the evolution of the flavor content of a neutrino beam emitted in a core-collapsing supernova. We obtain the analytical expressions for the contributions of GWs to the neutrino fluxes and for the damping decrement, which describes the attenuation of the fluxes to their asymptotic values. We find that the contribution to the evolution of neutrino fluxes from GWs, emitted by merging supermassive black holes, dominates over that from black holes with stellar masses. The implication of the obtained results for the measurement of astrophysical neutrinos with neutrino telescopes is discussed.

description: The usual formulations of quantum field theory in Minkowski spacetime make crucial use of features--such as Poincare invariance and the existence of a preferred vacuum state--that are very special to Minkowski spacetime. In order to generalize the formulation of quantum field theory to arbitrary globally hyperbolic curved spacetimes, it is essential that the theory be formulated in an entirely local and covariant manner, without assuming the presence of a preferred state. We propose a new framework for quantum field theory, in which the existence of an Operator Product Expansion (OPE) is elevated to a fundamental status, and, in essence, all of the properties of the quantum field theory are determined by its OPE. We provide general axioms for the OPE coefficients of a quantum field theory. These include a local and covariance assumption (implying that the quantum field theory is locally and covariantly constructed from the spacetime metric), a microlocal spectrum condition, an "associativity" condition, and the requirement that the coefficient of the identity in the OPE of the product of a field with its adjoint have positive scaling degree. We prove curved spacetime versions of the spin-statistics theorem and the PCT theorem. Some potentially significant further implications of our new viewpoint on quantum field theory are discussed.

description: A formula of the $D$-$D$ correlation function is derived. The deuterons are treated either as elementary particles or as neutron-proton bound states. In the first case the deuterons are directly emitted from a source and in the second one the deuteron formation is a final-state process simultaneous with a generation of $D$-$D$ correlation. The source radius of deuterons formed due to final-state interactions is bigger by the factor of $\sqrt{2}$ than that of directly emitted deuterons. To check how sizable is the effect we compute the $D$-$D$ correlation function taking into the Bose-Einstein statistics of deuterons, the $s$-wave scattering due to strong interaction and the Coulomb repulsion. The correlation function is shown to be sensitive to the source radius for sources which are sufficiently small with RMS radii smaller than 3.5 fm. Otherwise the correlation function is dominated by the Coulomb repulsion and weakly depends on the source radius. Measurements which can make use of our finding are discussed.

description: Es wurde untersucht, inwiefern verschiedene wässrige Behandlungen die Dimensionen eines geprägten Reliefs auf Papier verändern. Zu diesem Zweck wurden Testreihen mit Blindprägedrucken durchgeführt. Während ein Teil der dafür angefertigten Probekörper verschiedenen wässrigen Behandlungen unterzogen wurde, blieb ein anderer Teil unbehandelt. Anschließend wurden die Dimensionen der geprägten Reliefs aus beiden Gruppen mit einem 3D-Profilometer vermessen. Bei allen behandelten Probekörpern wurden Dimensionsveränderungen festgestellt, die jedoch ohne Vergleichsbild mit dem bloßen Auge nicht wahrnehmbar sind. Die Wässerungsdauer, Wässerungszusätze, der Einsatz von Bleichmedien sowie die Grammatur des Papiers haben die Dimensionsstabilität der geprägten Reliefs kaum beeinflusst, während der zyklische Wechsel zwischen wässriger Behandlung und Trocknung und die Zusammensetzung des Papiers zu stärkeren Veränderungen führen. Auf Grundlage dieser Ergebnisse wurde eine Risikoeinschätzung und ein Behandlungskonzept für den Prägedruck Hommage à Fontana des Künstlers Günther Uecker erarbeitet.

description: We construct, somewhat non-standard, Legendrian surgery diagrams for some Stein fillable contact structures on some plumbing trees of circle bundles over spheres. We then show how to put such a surgery diagram on the pages of an open book for $S^3,$ with relatively low genus. Thus we produce open books with low genus pages supporting these Stein fillable contact structures, and in many cases it can be shown that these open books have minimal genus pages.

description: We explore the prospects for direct detection of dark energy by current and upcoming terrestrial dark matter direct detection experiments. If dark energy is driven by a new light degree of freedom coupled to matter and photons then dark energy quanta are predicted to be produced in the Sun. These quanta free-stream towards Earth where they can interact with Standard Model particles in the detection chambers of direct detection experiments, presenting the possibility that these experiments could be used to test dark energy. Screening mechanisms, which suppress fifth forces associated with new light particles, and are a necessary feature of many dark energy models, prevent production processes from occurring in the core of the Sun, and similarly, in the cores of red giant, horizontal branch, and white dwarf stars. Instead, the coupling of dark energy to photons leads to production in the strong magnetic field of the solar tachocline via a mechanism analogous to the Primakoff process. This then allows for detectable signals on Earth while evading the strong constraints that would typically result from stellar probes of new light particles. As an example, we examine whether the electron recoil excess recently reported by the XENON1T collaboration can be explained by chameleon-screened dark energy, and find that such a model is preferred over the background-only hypothesis at the $2.0σ$ level, in a large range of parameter space not excluded by stellar (or other) probes. This raises the tantalizing possibility that XENON1T may have achieved the first direct detection of dark energy. Finally, we study the prospects for confirming this scenario using planned future detectors such as XENONnT, PandaX-4T, and LUX-ZEPLIN.

description: This paper aims to measure the efficiency of urban street networks (a kind of complex networks) from the perspective of the multidimensional chain of connectivity (or flow). More specifically, we define two quantities: flow dimension and flow capacity, to characterize structures of urban street networks. To our surprise for the topologies of urban street networks, previously confirmed as a form of small world and scale-free networks, we find that (1) the range of their flow dimension is rather wider than their random and regular counterparts, (2) their flow dimension shows a power-law distribution, and (3) they have a higher flow capacity than their random and regular counterparts. The findings confirm that (1) both the wider range of flow dimension and the higher flow capacity can be a signature of small world networks, and (2) the flow capacity can be an alternative quantity for measuring the efficiency of networks or that of the individual nodes. The findings are illustrated using three urban street networks (two in the Europe and one in the USA).

description: Οι εμπορικές μισθώσεις αποτελούν μία ιδιάζουσα κατηγορία μισθώσεων οι οποίες διακρίνονται σε αρκετά σημεία από τις κοινές αστικές μισθώσεις. Ρυθμίζονται αυτοτελώς από το Προεδρικό Διάταγμα 34/1995, η πιο πρόσφατη τροποποίηση του οποίου έγινε με το νόμο 4242/2014, ο οποίος εισήγαγε τη διαφοροποίηση των νεότερων εμπορικών μισθώσεων – ήτοι των καταρτισθεισών μετά τη δημοσίευση του ως άνω νόμου (28.02.2014) – από τις προ του νόμου αυτού καταρτισθείσες. Η ιδιαίτερη και πιο στοχευμένη ρύθμιση των εμπορικών μισθώσεων επιβλήθηκε εξαρχής για ποικίλους λόγους. Αφενός μεν, για την προστασία του μισθωτή, η οποία εξασφαλίζεται από την απρόσκοπτη και μακρόχρονη λειτουργία της επιχείρησής του σε συγκεκριμένους χώρους, αφετέρου δε για την ενίσχυση της εθνικής οικονομίας. Σκοπός της παρούσας εργασίας είναι να αναλυθούν όλοι οι λόγοι με βάση τους οποίους μπορεί να λυθεί μία εμπορική-επαγγελματική μίσθωση. Οι λόγοι αυτοί διακρίνονται σε δύο κατηγορίες αναλόγως με τον αν η λήξη επέρχεται με καταγγελία (ανεξαρτήτως από την ειδικότερη νομική της θεμελίωση) ή χωρίς καταγγελία της μίσθωσης. Λόγοι και των δύο κατηγοριών ανευρίσκονται τόσο στον ΑΚ όσο και στο ΠΔ 34/1995
description: Commercial leases are a particular category of leases that can be distinguished in several aspects from common urban leases. They are regulated separately by Presidential Decree 34/1995, the most recent amendment of which was introduced by Law 4242/2014, which introduced the diversification of newer commercial leases - that is, those signed after the publication of the above law (28.02.2014) - from those prepared before this law. The special and more targeted regulation of commercial leases was imposed from the outset for a variety of reasons. On the one hand, for the protection of the tenant, which is ensured by the uninterrupted and prolonged operation of his business in particular places, and on the other, to strengthen the national economy. The purpose of this paper is to analyze all the reasons why a commercial lease can be terminated. These grounds fall into two categories, depending on whether the termination is due to a complaint (irrespective of its more specific legal basis) or not. Reasons from both categories are found in the Civil Code as well as the PD 34/1995
