description: Σκοπός της παρούσας εργασίας ήταν η αναζήτηση των κοινών στοιχείων μεταξύ των Λουίτζι Πιραντέλλο και Ίταλο Καλβίνο αναφορικά με την ηθική, τις ανθρώπινες ανάγκες και τις κοινωνικές συμβάσεις που διέπουν τις ερωτικές σχέσεις και το γάμο, σε δύο διακριτές χρονικές περιόδους της ιταλικής ιστορίας. Με βάση τα παραπάνω εξετάσαμε τρία, αντιπροσωπευτικά κατά τη γνώμη μας, διηγήματα κάθε συγγραφέα στα οποία αναπαρίσταται ρεαλιστικά η καθημερινότητα των απλών ανθρώπων και αναδεικνύεται η κοινή οπτική των συγγραφέων απέναντι στα ανθρώπινα πάθη
description: The aim of the present thesis was the search for common elements between Luigi Pirandello and Italo Calvino regarding ethics, human needs and social conventions governing loving affairs and marriage, in two distinctive eras of the Italian history. According to these, we analyzed three representative, in our opinion, short stories of each writer, in which the everyday life of ordinary people is realistically depicted and the common view of the writers regarding human passions emerges.

description: Additional file 6. Genetic diversity of BVDV-1 in France. Maximum likelihood phylogenetic tree was inferred from 1316 French isolates and international reference strains. Tips coloured in yellow and blue denote previously published French and reference sequences, respectively. Asterisks indicate samples that are identical or almost identical to vaccine strains. The tree was midpoint rooted. Solid bars at right correspond to BVDV-1 genotype delimitations based on reference strains. Statistical support for nodes were assessed using an ultrafast bootstrap (UFBoot, 1000 replicates) and a Shimodaira–Hasegawa approximate likelihood-ratio test (SH-aLRT, 1000 replicates). Diamonds at internal nodes denote well-supported clades with UFboot ≥ 95% and SH-aLRT >= 80% as suggested by IQ-TREE documentation.

description: We consider the equation $- Δu+V(x)u- k(\Del(|u|^{2}))u=g(x,u), u>0, x \in {\BR}^2,$ where $V:{\BR}^2\to {\BR}$ and $g:{\BR}^2 \times {\BR}\to {\BR}$ are two continuous $1-$periodic functions. Also, we assume $g$ behaves like $\exp (β|u|^4)$ as $|u|\to \infty.$ We prove the existence of at least one weak solution $u \in H^1({\BR}^2)$ with $u^2 \in H^1({\BR}^2).$ Mountain pass in a suitable Orlicz space together with Moser-Trudinger are employed to establish this result. Such equations arise when one seeks for standing wave solutions for the corresponding quasilinear Schrödinger equations. Schrödinger equations of this type have been studied as models of several physical phenomena. The nonlinearity here corresponds to the superfluid film equation in plasma physics.

description: Nanoindentation tests were performed at several temperatures (24 to 80degC) on one antiwear zinc dialkyl-dithiophosphate (ZDTP) tribofilm using a Nanoindenter XP (R) entirely set into a climatic chamber. Mechanical properties of the tribofilm were determined using a simple model. AFM observations were conducted to estimate the order of magnitude of the film's thickness. The effect of applied pressure on the elastic properties was demonstrated and taken into account in the present analysis. The use of the F/S^2 parameter, independent of contact geometry, revealed a hardness dependency upon temperature. Furthermore, careful AFM observations of the residual pile-up produced by plastic flow around the indents pointed out the evolution of the film deformation process with temperature.

description: To progress in galactic studies based on open clusters, e.g. cluster formation rate or kinematical properties, one needs to improve the number of open clusters observed. However, only half of the 1700 known galactic open clusters have been properly observed so far, making any statistical investigation insignificant, especially at larger distances from the Sun. We study marginally investigated or neglected open clusters with Bessell CCD BVR photometry, whose data were used to fit isochrones to the individual color-magnitude diagrams. We examined the galactic clusters Basel 11b, King 14 and Czernik 43, the last being observed for the first time to this extent. As well as a careful comparison to available photometry, their parameters such as age, interstellar reddening, distance and apparent diameter were determined. The obtained cluster properties were verified by near infrared 2MASS data. The three investigated intermediate age clusters are all located in the galactic disk with distances between 1.8 and 3.0kpc from the Sun.

description: We review the theory and phenomenology of effective supergravity theories based on orbifold compactifications of the weakly-coupled heterotic string. In particular, we consider theories in which the four-dimensional theory displays target space modular invariance and where the dilatonic mode undergoes Kahler stabilization. A self-contained exposition of effective Lagrangian approaches to gaugino condensation and heterotic string theory is presented, leading to the development of the models of Binetruy, Gaillard and Wu. Various aspects of the phenomenology of this class of models are considered. These include issues of supersymmetry breaking and superpartner spectra, the role of anomalous U(1) factors, issues of flavor and R-parity conservation, collider signatures, axion physics, and early universe cosmology. For the vast majority of phenomenological considerations the theories reviewed here compare quite favorably to other string-derived models in the literature. Theoretical objections to the framework and directions for further research are identified and discussed.

description: The bulk quaternary equiatomic CoCrFeNi alloy is studied extensively in literature. Under experimental conditions, it shows a single-phase fcc structure and its physical and mechanical properties are similar to those of the quinary equiatomic CoCrFeMnNi alloy. Many studies in literature have focused on the mechanical properties of bulk nanocrystalline high entropy alloys or compositionally complex alloys, and their microstructure evolution upon annealing. The thin film processing route offers an excellent alternative to form nanocrystalline alloys. Due to the high nucleation rate and high density of defects in thin films synthesized by sputtering, the kinetics of microstructure evolution is often accelerated compared to those taking place in the bulk. Here, thin films are used to study the phase evolution in nanocrystalline CoCrFeNi deposited on Si/SiO 2 and c-sapphire substrates by magnetron cosputtering from elemental sources. The phases and microstructure of the films are discussed in comparison to the bulk alloy. The main conclusion is that second phases can form even at room temperature provided there are sufficient nucleation sites.

description: Hybrid derivatives of modified homo-aza-steroids with cytotoxic drugs, such as alkylating agents, have been in the center of research on cancer treatment for years. These derivatives express interesting biological properties due to their increased anti-cancer activity and to their selectivity towards cancer cells without affecting the healthy ones, thus reducing the toxic side effects of conventional methods, such as chemotherapy. Quinolones, on the other hand, are a large family of compounds with antibiotic properties widely used to treat bacterial infections. However, it has been observed that these molecules also exhibit antitumor activity in some cases. In the present postgraduate work were synthesizes four homo-aza-steroids, testosterone, estrone and adrenosterone conjugated with an alkylating agent, an anticancer agent and four fluoroquinolone antibiotics. These derivatives were coupled either via amide, ester or carbamic bonds and the results of their biological activity on various cancer cell lines are expected

description: Field quantization in 5D flat and warped space-times with Z$_2$-parity is comparatively examined. We carefully and closely derive 5D position/momentum(P/M) propagators. Their characteristic behaviours depend on the 4D (real world) momentum in relation to the boundary parameter ($l$) and the bulk curvature ($\om$). They also depend on whether the 4D momentum is space-like or time-like. Their behaviours are graphically presented and the Z$_2$ symmetry, the "brane" formation and the singularities are examined. It is shown that the use of absolute functions is important for properly treating the singular behaviour. The extra coordinate appears as a {\it directed} one like the temperature. The $δ(0)$ problem, which is an important consistency check of the bulk-boundary system, is solved {\it without} the use of KK-expansion. The relation between P/M propagator (a closed expression which takes into account {\it all} KK-modes) and the KK-expansion-series propagator is clarified. In this process of comparison, two views on the extra space naturally come up: orbifold picture and interval (boundary) picture. Sturm-Liouville expansion (a generalized Fourier expansion) is essential there. Both 5D flat and warped quantum systems are formulated by the Dirac's bra and ket vector formalism, which shows the warped model can be regarded as a {\it deformation} of the flat one with the {\it deformation parameter} $\om$. We examine the meaning of the position-dependent cut-off proposed by Randall-Schwartz.

Spatial memory changes in adulthood
Creators: name: Uttl, Bob
Publisher: name: University of British Columbia

description: The main goal of the research was to increase our understanding of spatial memory changes in adulthood. Four questions were examined in two experiments. Do age-related changes in spatial memory occur in real-life situations? If so, do they increase linearly across the adult lifespan? Do older adults benefit more than young adults from being informed about an upcoming memory test? Do age-related changes in performance depend on the type of spatial memory test? The first experiment involved a real-life setting~a science center exhibit on memory. Subjects were 302 visitors to the exhibit (approximately equal numbers of men and women), and ranged in age from 15 to 74 years. They were asked to recollect the locations of items displayed in the exhibit. For these subjects, spatial memory remained stable until about 60 years of age, and then declined sharply. The second experiment, conducted in a laboratory, was designed to examine age-related changes in spatial memory under more controlled conditions, while keeping the tasks as similar as possible to a real-life situation. For that purpose, subjects were asked to play the role of a secretary in a simulated office. Subjects were 64 university undergraduates (mean age = 20.1 years) and 32 adults over 65 years of age (mean age = 71.2 years). Half of subjects in each age-group were informed that spatial memory would be tested, whereas others were not. Subjects were required to recollect the locations of items they had used to complete a series of secretarial tasks, either by indicating their locations on a map of the office (the map test), or by relocating them in the office (the relocation test). The results of this experiment showed that (1) the intentional instructions improved spatial memory test performance of older but not young adults, (2) both older and young adults performed higher on the relocation test than on the map test, but (3) advantage due to the relocation test was larger for older than for young adults. The results of both experiments are discussed within a modified transfer-appropriate-processing (TAP) view (cf., Morris, Bransford, & Franks, 1977). This view claims that performance on any memory test is dependent on the degree of overlap between mental operations employed at study and test (Kolers, 1975, 1979). An extension of this view states (Craik, 1983) that study and test tasks can be arranged on a continuum that reflects the extent to which performance depends on subject-initiated processing, and the extent to which it is initiated and guided by the environment. The environmental support includes the cues present at test and instructions given to subjects (Graf, 1990, 1991). According to the modified TAP view, older adults experience difficulty carrying out selfinitiated processing, and are, therefore, more dependent than young adults on environmental support to initiate and guide processes required for effective remembering (Craik, 1983; Graf, 1990).

description: We employ constraints to control the parameter space of deep neural networks throughout training. The use of customized, appropriately designed constraints can reduce the vanishing/exploding gradients problem, improve smoothness of classification boundaries, control weight magnitudes and stabilize deep neural networks, and thus enhance the robustness of training algorithms and the generalization capabilities of neural networks. We provide a general approach to efficiently incorporate constraints into a stochastic gradient Langevin framework, allowing enhanced exploration of the loss landscape. We also present specific examples of constrained training methods motivated by orthogonality preservation for weight matrices and explicit weight normalizations. Discretization schemes are provided both for the overdamped formulation of Langevin dynamics and the underdamped form, in which momenta further improve sampling efficiency. These optimization schemes can be used directly, without needing to adapt neural network architecture design choices or to modify the objective with regularization terms, and see performance improvements in classification tasks.

description: Mechanisms for the production of $^1S_0$ diproton pairs, ${pp}_s$, in the $pd\to {pp}_s n$ reaction are studied at proton beam energies 0.5 -- 2 GeV in kinematics similar to those of backward elastic $pd$ scattering. This reaction provides valuable information on the short-range $NN$ and $pd$ interactions that is complementary to that investigated in the well known $pd\to dp$ and $dp\to p(0^\circ)X$ processes. The $pd\to {pp}_sn$ reaction is related to the subprocesses $π^0 d\to pn$ and $pN\to {pp}_s π$ using two different one--pion--exchange (OPE) diagrams. Within both these models a reasonable agreement could be obtained with the data below 1GeV. The similar energy dependence of the $pd\to\{pp\}_s n$ and $pd\to dp$ cross sections and the small ratio of about 1.5% in the production of $\{pp\}_s$ to deuteron final states follow naturally within the OPE models.

description: One of the major limitations of nanomedicine is the scarce penetration of nanoparticles in tumoral tissues. These constrains have been tried to be solved by different strategies, such as the employ of polyethyleneglycol (PEG) to avoid the opsonization or reducing the extracellular matrix (ECM) density. Our research group has developed some strategies to overcome these limitations such as the employ of pH-sensitive collagenase nanocapsules for the digestion of the collagen-rich extracellular matrix present in most of tumoral tissues. However, a deeper understanding of physicochemical kinetics involved in the nanocapsules degradation process is needed to understand the nanocapsule framework degradation process produced during the penetration in the tissue. For this, in this work it has been employed a double-fluorescent labelling strategy of the polymeric enzyme nanocapsule as a crucial chemical tool which allowed the analysis of nanocapsules and free collagenase during the diffusion process throughout a tumour-like collagen matrix. This extrinsic label strategy provides far greater advantages for observing biological processes. For the detection of enzyme, collagenase has been labelled with fluorescein Isothiocyanate (FITC), whereas the nanocapsule surface was labelled with rhodamine Isothiocyanate (RITC). Thus, it has been possible to monitor the hydrolysis of nanocapsules and their diffusion throughout a thick 3D Collagen gel during the time, obtaining a detailed temporal evaluation of the pH-sensitive collagenase nanocapsule behaviour. These collagenase nanocapsules displayed a high enzymatic activity in low concentrations at acidic pH, and their efficiency to penetrate into tissue models pave the way to a wide range of possible nanomedical applications, especially in cancer therapy.

description: Anomalies are known to appear in the perturbation theory for the one-dimensional Anderson model. A systematic approach to anomalies at critical points of products of random matrices is developed, classifying and analysing their possible types. The associated invariant measure is calculated formally. For an anomaly of so-called second degree, it is given by the groundstate of a certain Fokker-Planck equation on the unit circle. The Lyapunov exponent is calculated to lowest order in perturbation theory with rigorous control of the error terms.

description: The K x-ray spectra of different targets (Cu, Zn, and Ge) induced by 3 to 5 MeV/u Si projectile ions have been measured to determine the K-shell ionization cross-section. A significant difference is observed between the measurements and theoretical estimates, with the latter being about 50% below the experimental results. This underestimation} is attributed to the charge-exchange from target K-shell to projectile K- and L-shells. Such observation can only be possible if the projectile ions attain up to H- and He-like charge states. Corresponding projectile charge state fractions have been evaluated from the Lorentzian charge state distribution, where mean charge state is taken from the Fermi gas model [Phys. Rev. Lett. 30, 358 (1973)] and width from the Novikov and Teplova approach [Phys. Lett. A378, 1286-1289 (2014)]. The sum of the direct ionization cross-section and K-K + K-L capture cross-sections gives a good agreement with the measured cross-sections. Furthermore, we have validated this methodology with available data for Si-ion on Ti target. Such results may be useful in many solid target based applications.

Rational disagreement about social justice
Creators: name: Preinsperger, Kurt
Publisher: name: University of British Columbia
Year: 2008

description: Numerous conflicting theories about the just distribution of goods in society have emerged in response to John Rawls’ 1971 treatise A Theory of Justice. Given that informed persons continue to disagee strongly about the demands of social justice, progress may come from better understanding the underlying reasons for disagreement about justice among philosophically informed people of moral goodwill. In this dissertation I explore the idea, suggested by Larmore, Pogge, Ackerman and others, that some of the disagreement about justice among informed people of goodwill is “rational” disagreement. I identify, in the literature on social justice, recurrent conceptual, normative and empirical issues which we have reason to consider currently (or conceivably forever) irresolvable, at the first-order level of moral reasoning, by any information, arguments or methods accessible to us. But claims concerning the possibility of rational disagreement about justice only differ non-trivially from skepticism about justice if plausible limits can be set to the scope of this disagreement. To characterize such limits, I seek to establish the following two wide-reflective-equilibrium-based presumptions. (1) A consequentialist metaethical framework is our most credible approach to moral justification (where the form of consequentialism defended is constructivist, non-foundational, value-pluralistic, and includes distribution sensitivity among its ultimate values). (2) In moderately well-off, pluralistic societies, only those conceptions of justice fall within the scope of rational disagreement which propose broadly egalitarian-liberal, “directly responsive” principles (i.e. principles applicable to individual or group shares and not merely to basic social structure). Some likely candidates for the status of rational disagreements about social justice are discussed: the criteria definition and inclusion problems; various balancing problems related to attempts to increase the comprehensiveness of principles (the priority problem, the aggregation-distribution problem and commensuration problems); the domain demarcation problem; and problems of imprecision associated with justifying claims about justice within a consequentialist framework. An improved understanding of major sources of rational disagreement about social justice, as presented in this dissertation, helps define the normative weight of appeals to justice. This in turn clarifies the need to resolve many issues of social distribution otherwise than by relying on invocations of justice.

description: Σκοπός της μεταπτυχιακής εργασίας ήταν η έρευνα των ολιγοθέσιων δημοτικών σχολείων της Ελλάδας στη σύγχρονη εποχή. Ειδικότερα, εξετάσαμε τις απόψεις των δασκάλων και των γονέων για τα ολιγοθέσια δημοτικά σχολεία μέσω συνεντεύξεων. Αρχικά, κάναμε νύξη στο θεωρητικό πλαίσιο, που αφορούσε αυτού του τύπου σχολεία και στο οποίο στηρίχτηκε το μέρος της μεθοδολογίας. Αναφερθήκαμε στην έλλειψη ερευνών, που παρατηρήθηκε για τον τομέα των ολιγοθέσιων δημοτικών σχολείων στη ξένη και ελληνική βιβλιογραφία. Έπειτα, παρουσιάσαμε το μεθοδολογικό κομμάτι της εργασίας, το οποίο στηρίχτηκε στη ποιοτική έρευνα, και προβάλλαμε τα βήματα που ακολουθήσαμε σύμφωνα με αυτή. Στη συνέχεια, παραθέσαμε αναλυτικά, μέσα από τα αποσπάσματα των συνεντεύξεων, τα αποτελέσματα που προέκυψαν σχετικά με την εκπαιδευτική διαδικασία στα ολιγοθέσια δημοτικά σχολεία. Διαπιστώσαμε ότι υπήρχαν δύο αντίθετες πλευρές τόσο στις απόψεις των δασκάλων, όσο και των γονέων σχετικά με τη λειτουργία των ολιγοθέσιων δημοτικών σχολείων, οι οποίοι, μάλιστα, χωρίστηκαν σε πολέμιους και υποστηρικτές τους. Ένα άλλο θέμα που θίξαμε ήταν οι μέθοδοι διδασκαλίας που ακολουθούνταν σε αυτά και κατά πόσο εξυπηρετούσαν τις γνωστικές και κοινωνικοσυνασιθηματικές ανάγκες των παιδιών. Επίσης, θέσαμε υπό συζήτηση τον τρόπο με τον οποίο αντιμετωπίζονταν από την ελληνική πολιτεία
description: The aim of the present essay was the research of small elementary schools in modern Greece. We specifically examined teachers’ and parents’ opinions about the small elementary schools through interviews. Initially, we made mention of the theoretical framework, which referred to this type of schools and supported the methodological part of the essay. We stated the lack of researches about the small elementary schools in the foreign and Greek bibliography. Next, we presented the methodological part of the essay, which was based on the qualitative research, and we displayed all steps taken for this. Afterwards, we thoroughly reported, through the interviews’ extracts, on the results that emerged concerning the educational process in small elementary schools. We deduced that there are two opposite sides, both in teachers’ and parents’ views, concerning the running of small elementary schools, who were actually divided into their opponents and proponents. Another subject that we brought up were the teaching methods, which are being used in these schools, and how they cater to the students’ social-emotional needs. Furthermore, we have put up for discussion the way these schools are dealt with by the Greek government

description: We consider 'orbifold' and 'orientifold' field theories from the dual closed string theory side. We argue that a necessary condition for planar equivalence to hold is the absence of a closed string tachyonic mode in the dual non-supersymmetric string. We analyze several gauge theories on R3xS1. In the specific case of U(N) theories with symmetric/anti-symmetric fermions ('orientifold field theories') the relevant closed string theory is tachyon-free at large compactification radius (due to winding modes), but it develops a tachyonic mode below a critical radius. Our finding is with agreement with field theory expectations of a phase transition from a C-parity violating phase to a C-parity preserving phase as the compactification radius increases. In the case of U(N)xU(N) theories with bi-fundamental matter ('orbifold field theories') a tachyon is always present in the string spectrum, at any compactification radius. We conclude that on R4 planar equivalence holds for 'orientfiold field theories', but fails for 'orbifold field theories' daughters of N=4 SYM and suggest the same for daughters of N=1 SYM. We also discuss examples of SO/Sp gauge theories with symmetric/anti-symmetric fermions. In this case planar equivalence holds at any compactification radius -in agreement with the absence of tachyons in the string dual.

description: A comprehensive treatment of black hole thermodynamics in two-dimensional dilaton gravity is presented. We derive an improved action for these theories and construct the Euclidean path integral. An essentially unique boundary counterterm renders the improved action finite on-shell, and its variational properties guarantee that the path integral has a well-defined semi-classical limit. We give a detailed discussion of the canonical ensemble described by the Euclidean partition function, and examine various issues related to stability. Numerous examples are provided, including black hole backgrounds that appear in two dimensional solutions of string theory. We show that the Exact String Black Hole is one of the rare cases that admits a consistent thermodynamics without the need for an external thermal reservoir. Our approach can also be applied to certain higher-dimensional black holes, such as Schwarzschild-AdS, Reissner-Nordstrom, and BTZ.

Large-scale GHZ states through topologically protected zero-energy mode in a superconducting qutrit-resonator chain

description: We propose a superconducting qutrit-resonator chain model, and analytically work out forms of its topological edge states. The existence of the zero-energy mode enables to generate a state transfer between two ends of the chain, accompanied with state flips of all intermediate qutrits, based on which $N$-body Greenberger-Horne-Zeilinger (GHZ) states can be generated with great robustness against disorders of coupling strengths. Three schemes of generating large-scale GHZ states are designed, each of which possesses the robustness against loss of qutrits or of resonators, meeting a certain performance requirement of different experimental devices. With experimentally feasible qutrit-resonator coupling strengths and available coherence times of qutrits and resonators, it has a potential to generate large-scale GHZ states among dozens of qutrits with a high fidelity. Further, we show the experimental consideration of generating GHZ states based on the circuit QED system, and discuss the prospect of realizing fast GHZ states.

description: Using first-principles electronic structure calculations based on the Nth order muffin tin orbital (NMTO)-downfolding technique, we derived the low-energy spin model for CuTe2O5. Our study reveals that this compound is a 2D coupled spin-dimer system with the strongest Cu-Cu interaction mediated by two O-Te-O bridges. We checked the goodness of our model by computing the magnetic susceptibility with the Quantum Monte Carlo technique and by comparing it with available experimental data. We also present magnetization and specific heat results which may be compared with future experimental investigations. Our derived model is in disagreement with a recently proposed model for this compound [J. Deisenhofer et al, Phys. Rev. B,74 (2006) 174421]. The situation needs to be settled in terms of further experimental investigations.

Photon echo from lensing of fractional excitations in Tomonaga-Luttinger spin liquid

description: We study theoretically the nonlinear optical response of Tomonaga-Luttinger spin liquid in the context of terahertz (THz) two-dimensional coherent spectroscopy (2DCS). Using the gapless phase of the XXZ-type spin chain as an example, we show that its third-order nonlinear magnetic susceptibilities $χ^{(3)}_{+--+}$ and $χ^{(3)}_{-++-}$ exhibit photon echo, where $\pm$ refers to the left/right-hand circular polarization with respect to the $S^z$ axis. The photon echo arises from a ``lensing'' phenomenon in which the wave packets of fractional excitations move apart and then come back toward each other, amounting to a refocusing of the excitations' world lines. Renormalization group irrelevant corrections to the fixed point Hamiltonian result in dispersion and/or damping of the wave packets, which can be sensitively detected by lensing and consequently the photon echo. Our results thus unveil the strength of THz-2DCS in probing the dynamical properties of the collective excitations in a prototypical gapless many-body system.
