description: Τα ζώα αποτέλεσαν αντικείμενο μελέτης ήδη από την αρχαιότητα, όταν οι ειδικοί διεξήγαγαν έρευνα σε αυτά, έχοντας ως στόχο τη διερεύνηση της τοξικότητας των ουσιών. Με αυτόν τον τρόπο, αναδείχθηκαν οι βλαβερές ουσίες για τον άνθρωπο και παράλληλα κατέστη κατανοητή η δομή και η λειτουργία των οργανισμών. Με το πέρασμα των χρόνων, η έρευνα στα ζώα προσέφερε σημαντική ώθηση στην ιατρική και την φαρμακευτική, οι οποίες με τη σειρά τους συνετέλεσαν στην αντιμετώπιση των ασθενειών. Ωστόσο, δεν είναι μικρός ο αριθμός των ζώων που έχουν χρησιμοποιηθεί όλα αυτά τα χρόνια ως πειραματόζωα, γεγονός που οδήγησε στην προάσπιση των δικαιωμάτων τους από επιστήμονες και φιλοζωϊκές οργανώσεις. Αναγνωρίστηκε έτσι η αξία τους, κυρίως των πρωτευόντων θηλαστικών και ορίστηκε θεσμικό πλαίσιο σε ό,τι αφορά στη χρήση τους στην έρευνα. Παράλληλα, με την πάροδο των χρόνων, αναπτύχθηκαν εναλλακτικές μορφές πειραματισμού, κάποιες από τις οποίες απαλλάσσουν εντελώς τα ζώα από τις επίπονες διαδικασίες των πειραμάτων. Σύμφωνα, άλλωστε, με την Χριστιανική Ηθική, αναγνωρίζεται σαφώς στα ζώα η εγγενής αξία της ύπαρξής τους, καθώς αυτά αποτελούν κομμάτι του δημιουργικού έργου του Θεού. Παρ' όλ' αυτά, δεν παύει κορωνίδα της κτίσης να είναι ο άνθρωπος, γι' αυτό και τα ζώα υπάγονται στην κυριαρχία του. Ο Θεός τα δημιούργησε με σκοπό την εξυπηρέτηση των αναγκών του ανθρώπου, ο τελευταίος όμως καλείται να τα φροντίζει, κάνοντας έτσι σωστή χρήση του αυτεξουσίου του.
description: Experiments on animals date back to the ancient times, when specialists used to conduct tests in order to determine the toxicity levels of the substances. Due to these toxicology tests, people got to know which substances were poisonous to them, while scientists were acquainted with the form and function of the organisms. As the years went by, experiments on animals gave a great boost to Medicine and Pharmaceutics, which in turn, contributed to the cure of illnesses. However, the fact that, each year, a large number of animals is used in the fields of research, has led to the disappointment of many people. In other words, some scientists and animal activists have claimed the protection of law for the animals in research, especially for the primates. In the meantime, there has been an increase in the field of alternatives to animal testing, making it possible for the researchers not to use animals at all. Furthermore, towards the ethical approach of the use of animals, Christian ethics acknowledge the value of animals' life, given the fact that they are God's creatures too. However, man is the exceptional being of them all and thus, animals have been brought to life so as to serve his needs. It is crucial though, that he respects every other form of existence, so that there is a balanced relationship between man and nature.

description: Network-based approaches have proven to be essential to understand the molecular mechanisms underlying human diseases. The use of these methods has been boosted by the abundance of information about the genetic determinants of human diseases and of high quality interactomics data. The DisGeNET Cytoscape App is designed to enable the exploration of the genetic basis of human diseases from a network viewpoint. The app contains a set of functions to query, analyze, and visualize from different perspectives DisGeNET data (version 6.0): gene-disease, variant-disease and disease-disease networks. The functionalities of the app include querying DisGeNET data for specific diseases, genes, variants, and their combinations, and filtering the information by source, score, association type, evidence index, and by disease class. It also enables the annotation of networks of proteins and variants generated by other apps, or uploaded by the user. Finally, the app features a new automation module with functions to programmatically execute different tasks using popular programming languages such as R and Python. In summary, with its newly implemented functionalities the DisGeNET Cytoscape app provides the biomedical community with a tool that enables a systems-level analysis of human diseases in an automatic, reproducible way.

description: Works on lottery ticket hypothesis (LTH) and single-shot network pruning (SNIP) have raised a lot of attention currently on post-training pruning (iterative magnitude pruning), and before-training pruning (pruning at initialization). The former method suffers from an extremely large computation cost and the latter usually struggles with insufficient performance. In comparison, during-training pruning, a class of pruning methods that simultaneously enjoys the training/inference efficiency and the comparable performance, temporarily, has been less explored. To better understand during-training pruning, we quantitatively study the effect of pruning throughout training from the perspective of pruning plasticity (the ability of the pruned networks to recover the original performance). Pruning plasticity can help explain several other empirical observations about neural network pruning in literature. We further find that pruning plasticity can be substantially improved by injecting a brain-inspired mechanism called neuroregeneration, i.e., to regenerate the same number of connections as pruned. We design a novel gradual magnitude pruning (GMP) method, named gradual pruning with zero-cost neuroregeneration (\textbf{GraNet}), that advances state of the art. Perhaps most impressively, its sparse-to-sparse version for the first time boosts the sparse-to-sparse training performance over various dense-to-sparse methods with ResNet-50 on ImageNet without extending the training time. We release all codes in https://github.com/Shiweiliuiiiiiii/GraNet.

description: This work reports on the bulk properties of the quaternary Heusler alloy Co$_2$Mn$_{1-x}$Fe$_x$Si with the Fe concentration $x=$. All samples, which were prepared by arc melting, exhibit $L2_1$ long range order over the complete range of Fe concentration. Structural and magnetic properties of Co$_2$Mn$_{1-x}$Fe$_x$Si Heusler alloys were investigated by means of X-ray diffraction, high and low temperature magnetometry, M{öß}bauer spectroscopy, and differential scanning calorimetry. The electronic structure was explored by means of high energy photo emission spectroscopy at about 8 keV photon energy. This ensures true bulk sensitivity of the measurements. The magnetization of the Fe doped Heusler alloys is in agreement with the values of the magnetic moments expected for a Slater-Pauling like behavior of half-metallic ferromagnets. The experimental findings are discussed on the hand of self-consistent calculations of the electronic and magnetic structure. To achieve good agreement with experiment, the calculations indicate that on-site electron-electron correlation must be taken into account, even at low Fe concentration. The present investigation focuses on searching for the quaternary compound where the half-metallic behavior is stable against outside influences. Overall, the results suggest that the best candidate may be found at an iron concentration of about 50%.

A Pseudo-Photon in Non-Trivial Background Fields

description: We show that in the presence of external fields for which either $\dot{\vb{B}}^{\mathrm{ext}}\neq 0$ or $\nabla\times\vb{E}^{\mathrm{ext}}\neq 0$ it is not possible to derive the classical Maxwell equations from an action with only one gauge field. We suggest that one possible solution is to consider a second physical pseudo-vector gauge field $C$. The action for this theory is originally motivated by the inclusion of magnetic monopoles. These particles play no role in this work and our argument is only based in, that the violation of the Bianchi identities, cannot be accounted at the action level with only the standard gauge field. We give a particular example for a periodic rotating external magnetic field. Our construction holds that at classical level both the vector and pseudo-vector gauge fields $A$ and $C$ are regular. We compare pseudo-photon with paraphoton (graviphoton) theories concluding that, besides the mechanisms of gauge symmetry breaking already studied, the Bianchi identities violation are a crucial difference between both theories. We also show that, due to Dirac's quantization condition, at quantum field theory level the effects due to pseudo-photons and photons can be distinguished by the respective contributions to the magnetic moment of fermions and vacuum polarization. These effects may be relevant in astrophysical environments, namely close and inside neutron stars and magnetars. [Erratum: The construction in this work must, at most, be considered as a conceptual system or toy model. Are discussed systems where the results may have relevance.]

description: We report high-cadence H-alpha observations of a distinct Moreton wave observed at Kanzelhoehe Solar Observatory associated with the 3B/X3.8 flare and CME event of 2005 January 17. The Moreton wave can be identified in about 40 H-alpha frames over a period of 7 min. The EIT wave is observed in only one frame but the derived propagation distance is close to that of the simultaneously measured Moreton wave fronts indicating that they are closely associated phenomena. The large angular extent of the Moreton wave allows us to study the wave kinematics in different propagation directions with respect to the location of a polar coronal hole (CH). In particular we find that the wave segment whose propagation direction is perpendicular to the CH boundary (``frontal encounter'') is stopped by the CH which is in accordance with observations reported from EIT waves (Thompson et al. 1998). However, we also find that at a tongue-shaped edge of the coronal hole, where the front orientation is perpendicular to the CH boundary (the wave ``slides along'' the boundary), the wave signatures can be found up to 100 Mm inside the CH. These findings are briefly discussed in the frame of recent modeling results.

description: The Barbero-Immirzi (BI) connection, as usually introduced out of a spin connection, is a global object though it does not transform properly as a genuine connection with respect to generic spin transformations, unless quite specific and suitable gauges are imposed. We shall here investigate whether and under which global conditions a (properly transforming and hence global) SU(2)-connection can be canonically defined in a gauge covariant way. Such SU(2)-connection locally agrees with the usual BI connection and it can be defined on pretty general bundles; in particular triviality is not assumed. As a by-product we shall also introduce a global covariant SU(2)-connection over the whole spacetime (while for technical reasons the BI connection in the standard formulation is just introduced on a space slice) which restricts to the usual BI connection on a space slice.

Figuring torture: the representation of torture in a selection of novels
Creators: name: Pashka, Linda
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation examines the presentation of torture in a group of twentieth century novels--George Orwell’s "Nineteen Eighty-Four" (1949), Manlio Argueta’s "One Day of Life" (1983), Wessel Ebersohn’s "Store Up the Anger" (1981), J.M. Coetzee’s "Waiting for the Barbarians" (1981) and Lawrence Thornton’s "Imagining Argentina" (1987). The novels share scenes of physical torture performed by an agent of the state and aimed ostensibly at information-gathering, intimidation and/or ideological conversion. The structures of the representation of torture in these novels--tropes, narrative structure, narrative voice and focalisation—set out to arouse sympathy or empathy in the reader, thus writing against the notion of a polity that allows torture. Yet the same methods the novels employ to construct this sympathy often serve to reinforce the hierarchical binary model, patriarchal domination, which is seen in the novels to drive torture. Rather than subverting torture, then, the novels risk reinscribing it. They also share something of a project of resistance to the notion that torture constructs truth, although the structures they construct participate in the binary relations they critique. Vegetarian ecofeminists have evolved theories which are useful in the analysis of the structures at work in the novels to demonstrate the binary nature of torture in the novels. Torturers are presented as tropologically male figures dominating and metaphorically consuming their victims who are troped as female and animal, dominated and consumed. The reader of these texts is constructed in either of two positions which further reinforce the binary model; the text might build a reader who adopts a symbolically male voyeuristic gaze at the suffering victim or who identifies with the symbolically female tortured character. At the same time that it allows a critique of the hierarchised structure of torture as it is presented in the novels, vegetarian feminist theory also offers the possibility of methods of representing torture that break the cycle of torture.

description: Plasmonic hyperbolic metasurfaces have emerged as an effective platform for manipulating the propagation of light. Here, confined modes on arrays of silver nanoridges that exhibit hyperbolic dispersion are used to demonstrate and model a super-resolution imaging technique based on structured illumination microscopy. A spatial resolution of ~75 nm at 458 nm is demonstrated, which is 3.1 times better than an equivalent diffraction limited image. This work emphasizes the ability to engineer the properties of confined optical modes and to leverage those characteristics for applications in imaging. The results of this work could lead to improved approaches for super-resolution imaging using designed sub-wavelength structures.

Πιο συγκεκριμένα, εξετάζεται ο θεσμός της οικογένειας και ο τρόπος που η συγγραφέας αμφισβητεί την παραδοσιακή πυρηνική οικογένεια, με στόχο να επαναπροσδιορίσει αξίες παγιωμένες. Έτσι, γίνεται λόγος για τις διαφορετικές μορφές οικογένειας που σχολιάζονται στα έργα της, όπως για παράδειγμα την ομοφυλοφιλική οικογένεια. Ένα άλλο θέμα που θίγεται στη δραματουργία της Paula Vogel και εξετάζεται στην παρούσα εργασία, είναι η ασθένεια του AIDS και ο κοινωνικός της αντίκτυπος από τη δεκαετία του 1990 μέχρι και το ξεκίνημα του 21ου αιώνα. Επιπλέον, εξετάζονται οι θέσεις και οι απόψεις της συγγραφέως σχετικά με την παιδική και γυναικεία κακοποίηση, καθώς επίσης σχολιάζονται και οι αντιφάσεις του αμερικανικού έθνους. Στο δεύτερο μέρος της εργασίας, αναλύονται οι συνηθέστερες τεχνικές που χρησιμοποιεί η Vogel στα θεατρικά της κείμενα, όπως επίσης και οι επιρροές της.
description: The aim of this master is the study of the plays of the American playwright Paula Vogel and the commentary of the techniques she makes use of to broach questions and issues that affect the modern society. More specifically, we study the institution of the family and the way that the playwright questions the traditional nuclear family, with the aim to redefine entrenched ideas. So, we mention the different types of families that referred in her plays, like the homosexual family. Another issue that prevails in Paula Vogel’s dramaturgy and is examined in this master, is the AIDS disease and its social repercussion, from the 1990 decade till the beginning of the 21st century. Moreover, we study the views of the playwright concerning child abuse and violence towards women, as well as the contradictions of the American nation. In the second part of this master, we examine the techniques that Vogel uses more often in her plays, as well as her influences.

description: The present thesis presents a part of a late Hellenistic – early Roman cemetery situated at the intersection of Agiou Konstantinou and Geraniou Street in Athens. The cemetery is dated in a frame from the 2nd cent. BC to the 2nd cent. AD. Topographical and historical information is researched, as the cemetery is placed outside the Acharnian Gate of the Athens City Wall and at a time when Athens was undergoing a transitional period with many changes in political, economic and social level. The catalogue of vases of the funerary ensembles is presented. The aim of the thesis is to examine in detail the vases, while putting emphasis on the typology and evolution of clay and glass unguentaria distinguishing groups for more precise chronological classification. Also, the typology of the graves was further examined as well as the information derived from the burial customs.
Extremely Correlated Superconductors

description: Superconductivity in the t-J model is studied by extending the recently introduced extremely correlated fermi liquid theory. Exact equations for the Greens functions are obtained by generalizing Gor'kov's equations to include extremely strong local repulsion between electrons of opposite spin. These equation are expanded in a parameter $λ$ representing the fraction of double occupancy, and the lowest order equations are further simplified near $T_c$, resulting in an approximate integral equation for the superconducting gap. The condition for $T_c$ is studied using a model spectral function embodying a reduced quasiparticle weight $Z$ near half-filling, yielding an approximate analytical formula for $T_c$. This formula is evaluated using parameters representative of single layer High-$T_c$ systems. In a narrow range of electron densities that is necessarily separated from the Mott-Hubbard insulator at half filling, we find superconductivity with a typical $T_c$$\sim$$10^2$K.

Sustainable development in the Vancouver-Seattle corridor: a system for transborder planning
Creators: name: Patrinick, Steve Jay
Publisher: name: University of British Columbia
Year: 2009

description: The implementation of planning goals and objectives, including the goal of regional sustainability, requires cooperation and a degree of social unity, or cohesion, within society. In large, complex societies, a system of legally established planning mechanisms is also required to make and implement the public policies that express societal goals and objectives. In many regions, such as the Vancouver—Seattle Corridor, planners have another obstacle to implementing their communities’ visions: jurisdictional boundaries that segment otherwise contiguous populations. In order to effectively implement the common goals and values of such a divided region, a planning system is needed that will transcend political boundaries. Many multijurisdictional regions have developed mechanisms in order to make and implement policies, and to provide advice to governing authorities. These mechanisms are considered as possible models for the components of a transborder planning system for sustainable development in the Vancouver—Seattle Corridor. A theoretical planning system is constructed and presented to a set of targeted individuals for evaluation. Many conflicts emerge between the theoretical planning system and the political realities of the study region. The goal of sustainability requires the resolution of such conflicts in the Vancouver—Seattle Corridor and in other planning regions.

description: We map certain highly correlated electron systems on lattices with geometrical frustration in the motion of added particles or holes to the spatial defect-defect correlations of dimer models in different geometries. These models are studied analytically and numerically. We consider different coverings for four different lattices: square, honeycomb, triangular, and diamond. In the case of hard-core dimer covering, we verify the existed results for the square and triangular lattice and obtain new ones for the honeycomb and the diamond lattices while in the case of loop covering we obtain new numerical results for all the lattices and use the existing analytical Liouville field theory for the case of square lattice.The results show power-law correlations for the square and honeycomb lattice, while exponential decay with distance is found for the triangular and exponential decay with the inverse distance on the diamond lattice. We relate this fact with the lack of bipartiteness of the triangular lattice and in the latter case with the three-dimensionality of the diamond.

description: Video coding algorithms encode and decode an entire video frame while feature coding techniques only preserve and communicate the most critical information needed for a given application. This is because video coding targets human perception, while feature coding aims for machine vision tasks. Recently, attempts are being made to bridge the gap between these two domains. In this work, we propose a video coding framework by leveraging on to the commonality that exists between human vision and machine vision applications using cuboids. This is because cuboids, estimated rectangular regions over a video frame, are computationally efficient, has a compact representation and object centric. Such properties are already shown to add value to traditional video coding systems. Herein cuboidal feature descriptors are extracted from the current frame and then employed for accomplishing a machine vision task in the form of object detection. Experimental results show that a trained classifier yields superior average precision when equipped with cuboidal features oriented representation of the current test frame. Additionally, this representation costs $7\%$ less in bit rate if the captured frames are need be communicated to a receiver.

description: We consider the problem of secure distributed matrix multiplication (SDMM). Coded computation has been shown to be an effective solution in distributed matrix multiplication, both providing privacy against workers and boosting the computation speed by efficiently mitigating stragglers. In this work, we present a non-direct secure extension of the recently introduced bivariate polynomial codes. Bivariate polynomial codes have been shown to be able to further speed up distributed matrix multiplication by exploiting the partial work done by the stragglers rather than completely ignoring them while reducing the upload communication cost and/or the workers' storage's capacity needs. We show that, especially for upload communication or storage constrained settings, the proposed approach reduces the average computation time of SDMM compared to its competitors in the literature.

description: Η παρούσα ερευνητική εργασία ασχολείται με τους εκπαιδευτές ενηλίκων και προσπαθεί -με τη χρήση του συστήματος Validpack- να καταγράψει τις ψυχοπαιδαγωγικές δεξιότητες που κατέχουν, για να ανταποκριθούν στον πολυσύνθετο ρόλο τους. Ιδιαίτερη βαρύτητα δίνεται στην ανίχνευση της συνεισφοράς του μη τυπικού / άτυπου πλαισίου στην απόκτηση των ψυχοπαιδαγωγικών δεξιοτήτων τους, καθώς και στη σημασία του εργασιακού περιβάλλοντος και της εργασιακής εμπειρίας, ως παραγόντων που ευνοούν τη Δια Βίου Μάθηση και τη γνωστική ανανέωση των εργαζομένων στο χώρο της εκπαίδευσης ενηλίκων. Όλα τα παραπάνω προσεγγίζονται υπό το πρίσμα της ευρωπαϊκής προσπάθειας που καταβάλλεται για την εγκυροποίηση (validation) των εφοδίων που αποκτώνται εκτός τυπικού εκπαιδευτικού πλαισίου και επιχειρείται να τεκμηριωθούν οι λόγοι που υπαγορεύουν την υιοθέτηση αυτής της πρακτικής από μέρους των ευρωπαϊκών χωρών. Για να σκιαγραφηθούν περισσότερο αποτελεσματικά τα στοιχεία αυτά, προτάσσεται στην εργασία θεωρητικό σκέλος, στο οποίο γίνεται εκτενής αναφορά σε θέματα σχετικά με τον εκπαιδευτή ενηλίκων (απαραίτητες δεξιότητες, σύγχρονος ρόλος, ζητήματα εκπαίδευσης, πιστοποίησης, επαγγελματικής ανάπτυξης των εκπαιδευτών ενηλίκων κι επαγγελματοποίησης του κλάδου), αναπτύσσονται θεωρητικά σημαντικές λέξεις-κλειδιά (τυπική, μη τυπική, άτυπη μάθηση, εγκυροποίηση) και δίνονται οι κυριότερες ευρωπαϊκές αποφάσεις που συνηγορούν υπερ της αναγκαιότητας της εγκυροποίησης. Γίνεται, επίσης, πλήρης περιγραφή του ερευνητικού εργαλείου (Validpack), το οποίο χρησιμοποιήθηκε για τη συλλογή των ερευνητικών δεδομένων κι επιχειρείται η στάθμισή του στην ελληνική πραγματικότητα.

Anomalous magnetic phase diagram in low-carrier two-band systems and possible application to CeOs4Sb12

description: Magnetic properties under the external field are investigated in low-carrier two-band systems, which may explain the nontrivial phase boundary found in temperature vs. magnetic field diagram discovered in some materials, such as filled-skutterudite compound CeOs$_{4}$Sb$_{12}$. Analysis is made both for the periodic Anderson model with the small-dispersive $f$ band and the simplified two parabolic band model in the vicinity of the Fermi level. The magnetic susceptibilities are calculated by using the random phase approximation. It is shown that the maximum value of the magnetic susceptibility perpendicular to the external field is enhanced and yields the anomalous phase boundary. By applying the magnetic field, the phase boundary shifts to higher temperature region in the insulating state with a small band gap. On the other hand, the similar phase boundary also appears in the semi-metallic states, in which the structure of the density of states in the vicinity of the Fermi level and the finite temperature effect are essential.

description: We present a general set-up for inflation in string theory where the inflaton field corresponds to Wilson lines in compact space in the presence of magnetic fluxes. T-dualities and limits on the value of the magnetic fluxes relate this system to the standard D-brane inflation scenarios, such as brane-antibrane inflation, D3/D7 brane inflation and different configurations of branes at angles. This can then be seen as a generalised approach to inflation from open string modes. Inflation ends when the Wilson lines achieve a critical value and an open string mode becomes tachyonic. Then hybrid-like inflation, including its cosmic string remnants, is realized in string theory beyond the brane annihilation picture. Our formalism can be incorporated within flux-induced moduli stabilisation mechanisms in type IIB strings. Also, contrary to the standard D-brane separation, Wilson lines can be considered in heterotic string models. We provide explicit examples to illustrate similarities and differences of our mechanism to D-brane inflation. In particular we present an example in which the eta-problem present in brane inflation models is absent in our case. We have examples with both blue and red tilted spectral index and remnant cosmic string tension $Gμ\lesssim 10^{-7}$.

description: The phase diagram of the massive chiral Gross-Neveu model (the 1+1-dimensional Nambu-Jona-Lasinio model at large N) is investigated in the vicinity of the tricritical point. Using the derivative expansion, the grand canonical potential is cast into the form of a Ginzburg-Landau effective action. Minimization of this action by variational and numerical methods reveals both 1st and 2nd order phase transitions to a chiral crystal phase, separated by a tricritical line. These findings are contrasted to the massive Gross-Neveu model with discrete chiral symmetry where only 2nd order transitions have been observed.

Quantum behavior of a heavy impurity strongly coupled to a Bose gas

description: We investigate the problem of an infinitely heavy impurity interacting with a dilute Bose gas at zero temperature. When the impurity-boson interactions are short ranged, we show that boson-boson interactions induce a quantum blockade effect, where a single boson can effectively block or screen the impurity potential. Since this behavior depends on the quantum granular nature of the Bose gas, it cannot be captured within a standard classical-field description. Using a combination of exact quantum Monte Carlo methods and a truncated basis approach, we show how the quantum correlations between bosons lead to universal few-body bound states and a logarithmically slow dependence of the polaron ground-state energy on the boson-boson scattering length. Moreover, we expose the link between the polaron energy and the spatial structure of the quantum correlations, spanning the infrared to ultraviolet physics.
