description: The aim of the present thesis was the study of the dialectical relationship between the private realm and the public realm on the field of Greek Art Music. Specifically, we examined the ways, the means, the temporal, social and political background and the reasons based on which this dialectical relationship can be seen in Greek Art music. We attempted to analyze and describe the most important points of several social visions on the dialectical relationship between public and private realm in a more frame of reference, as well as to define and describe the characteristics of Greek Art music, in order to understand the music style we tried to analyze in this thesis. Consequently, based on the methods followed, we tried to show in detail, how the dialectical relationship between public and private realm was formed on the field of Greek Art Music. The disquisition of those listed above was completed through the following fields: a. the formulation of the subject areas of the art of writing lyrics since the birth of Greek Art music (1960) and until the end of the last century, and b. how autobiographical facts become public through the procedure of writing song lyrics. The methods used are literature review and content analysis.

description: Southern Spectroscopic Survey Telescope (SSST) is a wide-field spectroscopic survey telescope that China plans to build in Chile in the next few years. As an instrument for astronomical spectroscopic survey, the multi-object and fiber-fed spectrograph (MOFFS) is one of the most important scientific instruments for SSST. In this paper, we present a recommended optical design for the MOFFS system based on the Volume Phase Holographic Gratings (VPHG). The whole design philosophy and procedure, including the analytic method to determine the initial structure, optimization procedures of the VPHG and the camera groups, are demonstrated in detail. The numerical results of the final obtained spectrograph show a superior imaging quality and a relatively high transmittance for the whole working waveband and the field of view. The design method proposed in this paper can provide a reference for the design of MOFFS accommodated in spectroscopic survey telescopes.

description: Tourism destination networks are amongst the most complex dynamical systems, involving a myriad of human-made and natural resources. In this work we report a complex network-based systematic analysis of the Elba (Italy) tourism destination network, including the characterization of its structure in terms of a set of several traditional measurements, the investigation of its modularity, as well as its comprehensive study in terms of the recently reported superedges approach. In particular, structural (the number of paths of distinct lengths between pairs of nodes, as well as the number of reachable companies) and dynamical features (transition probabilities and the inward/outward activations and accessibilities) are measured and analyzed, leading to a series of important findings related to the interactions between tourism companies. Among the several reported results, it is shown that the type and size of the companies influence strongly their respective activations and accessibilities, while their geographical position does not seem to matter. It is also shown that the Elba tourism network is largely fragmented and heterogeneous, so that it could benefit from increased integration.

Earthquake risk mitigation of hospital facilities: a case study of Vancouver General Hospital
Creators: name: O'Hanley, Jean A.
Publisher: name: University of British Columbia
Year: 2008

description: The purpose of this study is to critically examine whether hospitals located in high seismic risk areas such as Vancouver can respond as post-disaster facilities in the aftermath of a major earthquake. Earthquake experience in California during the 1971 San Fernando and the 1989 Loma Prieta earthquakes in particular demonstrate that hospitals may be vulnerable and rendered unable to fully respond to their communities needs. In the case of earthquakes, risk management methods are limited to two strategies: pre-event mitigation to reduce the effects of the earthquake on life safety and loss of property; and providing recovery services after the event. In the case of post-disaster hospitals, experience shows that mitigation strategies ensure the functionality of the facility. Therefore, mitigation strategies must not only include structural mitigation to protect the life safety of its occupants, they must also include strategies which ensure the functionality of both the building operations as well as that of therapeutic and diagnostic medical equipment in the aftermath of an earthquake. Vancouver General Hospital is used as a case study to critically examine seismic pre-event mitigation strategies which include: the structures; building operation and medical equipment which are dependent on the supply of potable water and power. Findings of this study indicate that the current supply of potable water is not reliable and that some of VGH's essential building operations and medical equipment will not be functional due to losses in water pressures and disruptions in service. This study recommends that VGH should consider mitigation strategies which make the hospital independent of outside sources of both water and power supply in order to meet its emergency role as a post-disaster facility following an earthquake. The functionality of VGH in the aftermath of a major earthquake will be seriously curtailed unless there is adequate storage of potable water on site to meet the emergency needs of this hospital.

description: We show that a moving vortex lattice, as it comes to a crystal edge, radiates into a free space the harmonics of the washboard frequency, $ω_0=2πv/a$, up to a superconducting gap, $Δ/\hbar$. Here $v$ is the velocity of the vortex lattice and $a$ is the intervortex spacing. We compute radiation power and show that this effect can be used for generation of terahertz radiation and for characterization of moving vortex lattices.

description: Counterfactual quantum communication is unique in its own way that allows remote parties to transfer information without sending any message carrier in the channel. Although no message carrier travels in the channel at the time of successful information transmission, it is impossible to transmit information faster than the speed of light, thus without an information carrier. In this paper, we address an important question What carries the information in counterfactual quantum communication? and optimize the resource efficiency of the counterfactual quantum communication in terms of the number of channels used, time consumed to transmit 1-bit classical information between two remote parties, and the number of qubits required to accomplish the counterfactual quantum communication.

description: Artificial intelligence has changed our day to day life in multitude ways. AI technology is rearing itself as a driving force to be reckoned with in the largest industries in the world. AI has already engulfed our educational system, our businesses and our financial establishments. The future is definite that machines with artificial intelligence will soon be captivating over trained manual work that now is mostly cared by humans. Machines can carry out human-like tasks by new inputs as artificial intelligence makes it possible for machines to learn from experience. AI data from web of science database from 2008 to 2017 have been mapped to depict the average growth rate, relative growth rate, contribution made by authors in the view of research productivity, authorship pattern and collaboration of AI literature. The Lotka's law on authorship productivity of AI literature has been tested to confirm the applicability of the law to the present data set. A K-S test was applied to measure the degree of agreement between the distribution of the observed set of data against the inverse general power relationship and the theoretical value of α =2. It is found that the inverse square law of Lotka follow as such.

description: We collect a sample of stars observed both in LAMOST and Gaia which have colors implying a temperature hotter than 7000 K. We train a machine learning algorithm on LAMOST spectroscopic data which has been tagged with stellar classifications and metallicities, and use this machine to construct a catalog of Blue Horizontal Branch stars (BHBs) with metallicity information. Another machine is trained using Gaia parallaxes to predict absolute magnitudes for these stars. The final catalog of 13,693 BHBs is thought to be about 86\% pure, with $σ_{[Fe/H]}\sim$0.35 dex and $σ_{G}\sim$0.31 mag. These values are confirmed via comparison to globular clusters, although a covariance error seems to affect our magnitude and abundance estimates. We analyze a subset of this catalog in the Galactic Halo. We find that BHB populations in the outer halo appear redder, which could imply a younger population, and that the metallicity gradient is relatively flat around [Fe/H] = -1.9 dex over our sample footprint. We find that our metal rich BHB stars are on more radial velocity dispersion dominated orbits ($β\sim 0.70$) at all radii than our metal poor BHB stars ($β\sim 0.62$).

description: We present a result of searching for galaxy clusters that show an indication of global rotation using a spectroscopic sample of galaxies in SDSS and 2dFGRS. We have determined the member galaxies of 899 Abell clusters covered in SDSS and 2dFGRS using the redshift and the positional data of galaxies, and have estimated the ratio of the cluster rotation amplitude to the cluster velocity dispersion and the velocity gradient across the cluster. We have found 12 tentative rotating clusters that have large ratios of rotation amplitude to dispersion and large velocity gradients. We have determined the morphological parameters for 12 tentative rotating clusters using the positional information of the member galaxies: the ellipticity of the dispersion ellipse is in the range of 0.08$-$0.57, and the position angle of major or minor axis does not appear to be related to the position angle of rotation axis. We have investigated the substructures in the sample of tentative rotating clusters, finding from the Dressler-Shectman plots that the majority (9 out of 12) of clusters show an evidence of substructure due to the spatially correlated velocities of galaxies. We have selected six probable rotating clusters (A0954, A1139, A1399, A2162, A2169, and A2366) that show a single number density peak around the cluster center with a spatial segregation of the high and low velocity galaxies. We have found no strong evidences of a recent merging for the probable rotating clusters: the probable rotating clusters do not deviate significantly from the relation of the X-ray luminosity and the velocity dispersion or the virial mass of the clusters, and two probable rotating clusters (A0954 and A1399) have small values of the peculiar velocities and the clustercentric distances of the brightest cluster galaxies.

Formalization of Bohr's contextuality within theory of open quantum systems

Publisher: name: arXiv

description: In quantum physics, the notion of contextuality has a variety of interpretations which are typically associated with the names of their inventors, say Bohr, Bell, Kochen and Specker, and recently Dzhafarov. In fact, Bohr was the first who pointed to contextuality of quantum measurements as a part of formulation of his principle of complementarity. (Instead of "contextuality", he considered dependence on "experimental conditions.") Unfortunately, the contextuality counterpart of the complementarity principle was overshadowed by the issue of incompatibility of observables. And the interest for contextuality of quantum measurements rose again only in connection with the Bell inequality. The original Bohr's contextuality, as contextuality of each quantum measurement, was practically forgotten. It was highlighted in the works of the author of this paper, with applications both to physics and cognition. In this note, the theory of open quantum systems is applied to formalization of Bohr's contextuality within the the scheme of indirect measurements. This scheme is widely used in quantum information theory and it leads to the theory of quantum instruments (Davis-Lewis-Ozawa). In this scheme, Bohr's viewpoint on contextuality of quantum measurements is represented in the formal mathematical framework.

description: The evolution of gauge invariant second-order scalar perturbations in a general single field inflationary scenario are presented. Different second order gauge invariant expressions for the curvature are considered. We evaluate perturbatively one of these second order curvature fluctuations and a second order gauge invariant scalar field fluctuation during the slow-roll stage of a massive chaotic inflationary scenario, taking into account the deviation from a pure de Sitter evolution and considering only the contribution of super-Hubble perturbations in mode-mode coupling. The spectra resulting from their contribution to the second order quantum correlation function are nearly scale-invariant, with additional logarithmic corrections to the first order spectrum. For all scales of interest the amplitude of these spectra depend on the total number of e-folds. We find, on comparing first and second order perturbation results, an upper limit to the total number of e-folds beyond which the two orders are comparable.

description: The aim of this thesis is to study the evidence prohibitions, which are restrictions in the quest for substantive truth. In the first part, there is a theoretical approach of the basic concepts of evidence prohibitions, their subdivisions, and a brief overview of the major theories formulated about their purpose, their operation and their doctrinal foundation. Subsequently is searched the constitutional framework within evidence prohibitions exist today in the Greek legal system and some issues that arose after the explicit constitutional utilization prohibition of certain evidence by the article 19 par. 3 of the Constitution by the revisionist legislator in 2001 are exposed. Afterwards comes the main part of this thesis, which deals with the use of unlawfully acquired evidence in criminal procedure according to article 177 par. 2 CPC, the problems arising in the interpretation and application of this article, and the evaluation of the solutions provided by the theory as well as the case law of national courts and the ECHR. Finally, this thesis concludes with some conclusions and key positions.

description: The success of primordial nucleosynthesis has been limited by the long-standing Lithium problem. We use a self-consistent perturbative analysis of the effects of relevant theoretical parameters on primordial nucleosynthesis, including variations of nature's fundamental constants, to explore the problem and its possible solutions, in the context of the latest observations and theoretical modeling. We quantify the amount of depletion needed to solve the Lithium problem, and show that transport processes of chemical elements in stars are able to account for it. Specifically, the combination of atomic diffusion, rotation and penetrative convection allows us to reproduce the lithium surface abundances of Population II stars, starting from the primordial Lithium abundance. We also show that even with this depletion factor there is a preference for a value of the fine-structure constant at this epoch that is larger than the current laboratory one by a few parts per million of relative variation, at the two to three standard deviations level of statistical significance. This preference is driven by the recently noticed discrepancy between the best-fit values for the baryon-to-photon ratio (or equivalently the Deuterium abundance) inferred from cosmic microwave background and primordial nucleosynthesis analyses, and is largely insensitive to the Helium-4 abundance. We thus conclude that the Lithium problem most likely has an astrophysical solution, while the Deuterium discrepancy provides a possible hint of new physics.

description: Η υπολογιστική σκέψη αποτελεί ένα σύνολο δεξιοτήτων που αφορά και θα πρέπει να διαθέτουν όλοι οι άνθρωποι, ακριβώς όπως και οι ικανότητες γραφής, ανάγνωσης, αριθμητικής και είναι σημαντικό να εξασκείται από την παιδική ηλικία. Η υπολογιστική σκέψη είναι μία προσέγγιση για την επίλυση προβλημάτων με τρόπο που μπορεί να υλοποιηθεί με έναν υπολογιστή. Στόχος της παρούσας μελέτης ήταν η διερεύνηση της συμβολής των απτικών διεπαφών, που αποτελούν διεπαφές που χρησιμοποιούν φυσικά χειροπιαστά αντικείμενα για να υποστηρίξουν την αλληλεπίδραση του χρήστη με τον ψηφιακό κόσμο, στην ανάπτυξη δεξιοτήτων υπολογιστικής σκέψης. Το δείγμα ήταν 12 μαθητές, ηλικίας 8-9 ετών από ένα δημοτικό σχολείο στα περίχωρα της Θεσσαλονίκης. Μελετήθηκαν δεξιότητες της υπολογιστικής σκέψης και πως αυτές επηρεάζονται από την ενασχόληση με δραστηριότητες σε δύο είδους διεπαφές: μία απτική και μία γραφική διεπαφή. Τα αποτελέσματα έδειξαν ότι οι απτικές διεπαφές ενίσχυσαν στους μαθητές κάποιους τομείς που βοηθούν στην ανάπτυξη της υπολογιστικής σκέψης με ιδιαίτερη έμφαση στην συνεργατική επίλυση προβλημάτων. Στο τέλος της εργασίας παρουσιάζονται οι περιορισμοί της καθώς και προτάσεις για μελλοντικές έρευνες.
description: Computational thinking constitutes a skill that set concerns and should be acquired by all humans, from an early age, just like writing, reading and mathematical skills. Computational thinking is a problem solving approach, which refers to solving problems in a similar way that a computer does. The aim of the present study was the investigation of the contribution of tangible interfaces in the development of computational thinking skills. Tangible interfaces are those interfaces that use real tangible objects in order to support the interaction between the user and the digital world. The sample of the present study was 12 students, aged 8-9 years coming from a primary school in the suburbs of Thessaloniki. Two types of interfaces were used for the purposes of the present analysis: a tangible and a graphic interface and the engagement in each one was investigated regarding its influence on computational thinking with particular emphasis on collaborative problem solving. Limitations of the present study and recommendations for future studies are also presented in the last section of the dissertation.

description: We wish to minimize the resources used for network coding while achieving the desired throughput in a multicast scenario. We employ evolutionary approaches, based on a genetic algorithm, that avoid the computational complexity that makes the problem NP-hard. Our experiments show great improvements over the sub-optimal solutions of prior methods. Our new algorithms improve over our previously proposed algorithm in three ways. First, whereas the previous algorithm can be applied only to acyclic networks, our new method works also with networks with cycles. Second, we enrich the set of components used in the genetic algorithm, which improves the performance. Third, we develop a novel distributed framework. Combining distributed random network coding with our distributed optimization yields a network coding protocol where the resources used for coding are optimized in the setup phase by running our evolutionary algorithm at each node of the network. We demonstrate the effectiveness of our approach by carrying out simulations on a number of different sets of network topologies.

description: We use the millennium Arecibo 21 cm absorption-line survey measurements to examine the issue of the non-thermal contribution to the observed Galactic HI line widths. If we assume a simple, constant pressure model for the HI in the Galaxy, we find that the non-thermal contribution to the line width, v_{nt} scales as v^2_{nt} \propto l^α, for v_{nt} larger than \sim 0.7 km s^{-1}. Here l is a derived length scale and α\sim 0.7 \pm 0.1. This is consistent with what one would expect from a turbulent medium with a Kolmogorov scaling. Such a scaling is also predicted by theoretical models and numerical simulations of turbulence in a magnetized medium. For non-thermal line widths narrower than \sim 0.7 km s^{-1}, this scaling breaks down, and we find that the likely reason is ambiguities arising from Gaussian decomposition of intrinsically narrow, blended lines. We use the above estimate of the non-thermal contribution to the line width to determine corrected HI kinetic temperature. The new limits that we obtain imply that a significantly smaller (\sim 40% as opposed to 60%) fraction of the atomic interstellar medium in our Galaxy is in the warm neutral medium phase.

description: We present rest-frame $B$ and $I$ imaging of 35 low-redshift ($z < 0.5$) Palomar-Green quasars using the Hubble Space Telescope Wide Field Camera 3. We perform multi-component two-dimensional image decomposition to separate the host galaxy from its bright active nucleus, characterize its morphology, and measure its photometric properties. Special care is devoted to quantifying the structural parameters of the galaxy bulge, determine its $B-I$ color, and estimate its stellar mass. Roughly half of the sample, comprising the less luminous ($L_{5100} \lesssim 10^{45}\,\mathrm{erg\,s^{-1}}$) but most high Eddington ratio quasars, reside in disk galaxies that are often barred and possess pseudo bulges. The large stellar masses, large effective radii, and faint surface brightnesses suggest that the host galaxies of the most luminous quasars are mostly ellipticals. Major mergers constitute only a minority ($\lesssim 20\%$) of our sample. Our quasar sample roughly obeys the scaling relations between black hole mass and host galaxy (bulge, core, total) stellar mass. Hosts with black holes more massive than $\sim 10^8\,M_\odot$ behave similarly to classical bulges and early-type galaxies, while those with less massive black holes, particular the narrow-line Seyfert 1s, are consistent with pseudo bulges in late-type galaxies. The host galaxy bulges, irrespective of whether they are classical or pseudo, follow the relatively tight inverse relation between effective radius and mean effective surface brightness of inactive classical bulges and ellipticals. We argue that pseudo bulges experience recent or ongoing nuclear star formation.

V-like formations in flocks of artificial birds

Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: We consider flocks of artificial birds and study the emergence of V-like formations during flight. We introduce a small set of fully distributed positioning rules to guide the birds' movements and demonstrate, by means of simulations, that they tend to lead to stabilization into several of the well-known V-like formations that have been observed in nature. We also provide quantitative indicators that we believe are closely related to achieving V-like formations, and study their behavior over a large set of independent simulations.
A multi-component study of the administration and preservation of nitrate negatives
Creators: name: Reid, William S.
Publisher: name: University of British Columbia
Year: 2008

description: Cellulose nitrate negatives pose serious problems of preservation and accessibility to archival institutions, and create pressure on an archives physical and administrative resources. Archivists must take precautionary actions designed to prolong the life of the images in their care until they can be copied, and to safeguard against damage to other archival material that shares space with them. This thesis presents and discusses the issues surrounding the management of nitrate negatives in archival institutions of all sizes. The physical and chemical characteristics of cellulose nitrate, and its role in the historical development of photography introduces the specific archival concerns of preservation and access. A diplomatic analysis of the photographic negative, which shows that it does not need to be retained for evidentiary purposes, prompts the recommendation that cellulose nitrate negatives can be copied onto stable base film and then destroyed. The need for proper long term storage facilities is however recognised, and types of facilities are presented. Finally, this thesis provides guidelines for the preservation of cellulose nitrate negatives, and discusses the types of procedures presently in Canadian archival repositories. This thesis proposes that archivists concentrate their efforts towards the preservation of the information contained in the images themselves, rather than in their physical form, and thereby minimise the danger posed by the nitrate negatives by investing in a systematic copying program and in the construction of separate storage vaults.

description: This article introduces a symbolic formulation for the function ψ(t), conceived within the XChronos framework and the proposed RNA-XC (Chronon-based Artificial Neural Network). ψ(t) serves as a measure of subjective symbolic density over time, capturing perceptual presence, pause duration, and semantic weight. It forms the core of the ELAS equation (Limit Equation of Symbolic Activation), which defines when a Crônon — a unit of lived experiential time — emerges. This work bridges phenomenology, mathematical modeling, and artificial intelligence, offering an initial roadmap for developing AI systems capable of responding to meaning, not just data. Applications include reflective education, emotional UX design, and philosophical modeling of temporal awareness. The paper concludes with a call for neural architectures that listen to presence, recognize symbolic resonance, and operate with ontological sensitivity.
Stellar age versus mass of early-type galaxies in the Virgo Cluster

Year: 2008

description: The flux excess of elliptical galaxies in the far-ultraviolet can be reproduced by population synthesis models when accounting for the population of old hot helium-burning subdwarf stars. This has been achieved by Han and coworkers through a quantitative model of binary stellar evolution. Here, we compare the resulting evolutionary population synthesis model to the GALEX far-near ultraviolet colors (FUV-NUV) of Virgo cluster early-type galaxies that were published by Boselli and coworkers. FUV-NUV is reddest at about the dividing luminosity of dwarf and giant galaxies, and becomes increasingly blue for both brighter and fainter luminosities. This behavior can be easily explained by the binary model with a continuous sequence of longer duration and later truncation of star formation at lower galaxy masses. Thus, in contrast to previous conclusions, the GALEX data do not require a dichotomy between the stellar population properties of dwarfs and giants. Their apparently opposite behavior in FUV-NUV occurs naturally when the formation of hot subdwarfs through binary evolution is taken into account.

On the periodicity of Coxeter transformations and the non-negativity of their Euler forms

description: We show that for piecewise hereditary algebras, the periodicity of the Coxeter transformation implies the non-negativity of the Euler form. Contrary to previous assumptions, the condition of piecewise heredity cannot be omitted, even for triangular algebras, as demonstrated by incidence algebras of posets. We also give a simple, direct proof, that certain products of reflections, defined for any square matrix A with 2 on its main diagonal, and in particular the Coxeter transformation corresponding to a generalized Cartan matrix, can be expressed as $-A_{+}^{-1} A_{-}^t$, where A_{+}, A_{-} are closely associated with the upper and lower triangular parts of A.
