description: We report on the muon spin rotation/relaxation study of a pyrochlore oxide, Cd2Os2O7, which exhibits a metal-insulator (MI) transition at T_{MI}~225 K without structural phase transition. It reveals strong spin fluctuation (>10^8/s) below the MI transition, suggesting a predominant role of geometrical spin frustration amongst Os^{5+} ions. Meanwhile, upon further cooling, a static spin density wave discontinuously develops below T_{SDW}~150 K. These observations strongly suggest the occurrence of an anomalous magnetic transition and associated change in the local spin dynamics in undistorted pyrochlore antiferromagnet.

description: A way to simulate the basic interactions between two individuals with different opinions, in the context of strategic game theory, is proposed. Various games are considered, which produce different kinds of opinion formation dynamics. First, by assuming that all individuals (players) are equals, we obtain the bounded confidence model of continuous opinion dynamics proposed by Deffuant et al. In such a model a tolerance threshold is defined, such that individuals with difference in opinion larger than the threshold can not interact. Then, we consider that the individuals have different inclinations to change opinion and different abilities in convincing the others. In this way, we obtain the so-called ``Stubborn individuals and Orators'' (SO) model, a generalization of the Deffuant et al. model, in which the threshold tolerance is different for every couple of individuals. We explore, by numerical simulations, the dynamics of the SO model, and we propose further generalizations that can be implemented.

description: We study non-perturbative effects in four-dimensional N=1 supersymmetric orientifold compactifications due to D-brane instantons which are generically not invariant under the orientifold projection. We show that they can yield superpotential contributions via a multi-instanton process at threshold. Some constituents of this configuration form bound states away from the wall of marginal stability which can decay in other regions of moduli space. A microscopic analysis reveals how contributions to the superpotential are possible when new BPS states compensate for their decay. We study this concretely for D2-brane instantons along decaying special Lagrangians in Type IIA and for D5-branes instantons carrying holomorphic bundles in Type I theory.

description: A method is proposed to estimate the velocity field of an unsteady flow using a limited number of flow measurements. The method is based on a non-linear low-dimensional model of the flow and on expanding the velocity field in terms of empirical basis functions. The main idea is to impose that the coefficients of the modal expansion of the velocity field give the best approximation to the available measurements and that at the same time they satisfy as close as possible the non-linear low-order model. The practical use may range from feedback flow control to monitoring of the flow in non-accessible regions. The proposed technique is applied to the flow around a confined square cylinder, both in two- and three-dimensional laminar flow regimes. Comparisons are provided. with existing linear and non-linear estimation techniques.

description: We prove Helly-type theorems for line transversals to disjoint unit balls in $\R^{d}$. In particular, we show that a family of $n \geq 2d$ disjoint unit balls in $\R^d$ has a line transversal if, for some ordering $\prec$ of the balls, any subfamily of 2d balls admits a line transversal consistent with $\prec$. We also prove that a family of $n \geq 4d-1$ disjoint unit balls in $\R^d$ admits a line transversal if any subfamily of size $4d-1$ admits a transversal.
Ion transport in the ileum of the desert locust Schistocerca gregaria, forskal
Creators: name: Richardson, Naomi Dinah
Publisher: name: University of British Columbia
Year: 2008

description: Recently, Audsley (1991) purified a neuropeptide factor - scgITP from the copora cardiaca of Shistocerca gregaria. ScgITP stimulates ileal reabsorption of Cl⁻, K⁺, Na⁺ and fluid and inhibits acid secretion. Stimulation with scgITP causes an increase in both Cl⁻ dependent short-circuit current and transepithelial voltage (Vt) and a decrease in transepithelial resistance (Rt; Irvine et al 1988). There is evidence to suggest that cAMP acts as the second messenger for scgITP (Audsley 1990). In this thesis the mechanisms underlying ileal ion transport and the effects of cAMP were investigated. Intracellular microelectrodes were used to measure apical and basolateral membrane potentials. Brief transepithelial current pulses (13.3 μA) and ion substitutions permitted the estimation of specific ion conductances. In nonstimualted ilea, Vt was slightly positive (to the lumen side) and the inside of the cell was negative with respect to both haemolymph and lumen side bathing media. The apical membrane potential (Va) was slightly more negative than the basolateral membrane potential (Vb). Apical membrane resistance (Ra) was much higher than the basolateral membrane resitance (Rb). Stimulation of ileal ion transport with cAMP resulted in an increase in Vt. There was no change in Va after cAMP stimulation but Vb depolarized. Addition of cAMP caused a large decrease in Rt, due solely to a decrease in Ra with Rb remaining at control values. In nonstimulated ilea, a small apical Na⁺ conductance was measured. Voltage measurements indicated an increase in apical Na⁺ conductance after cAMP addition. However, resistance measurements were not consistent with a cAMP stimualted apical Na⁺ conductance. In nonstimulated ilea the conductance of the apical membrane to K⁺ was very small. After stimulation with cAMP a large increase in apical K⁺ conductance was observed. The cAMP stimulated apical K⁺ conductance was not inhibited by high luminal [K⁺]. The basolateral membrane displayed a very high conductance to K⁺ and to a lesser extent Cl⁻. There is no evidence for cAMP stimualtion of basolateral Cl⁻ conductance. These results are formulated into a model of the mechanism of cAMP control of ileal ion transport.

description: Only weakly interacting, neutrinos are the principal messengers reaching us from the center of a supernova. Terrestrial neutrino telescopes, such as SNO and SuperKamiokande, can provide precious information about the processes in the core of a collapsing and exploding star. But the information about the supernova that a neutrino detector can supply, is restricted by the fact that little experimental data on the neutrino-nucleus cross sections exists and by the uncertainties in theoretical calculations. In this letter, we propose a novel procedure that determines the response of a target nucleus in a supernova-neutrino detector directly, by using low-energy beta-beams. We show that fitting 'synthetic' spectra, constructed by taking linear combinations of beta-beam spectra, to the original supernova-neutrino spectra reproduces the folded differential cross sections very accurately. Comparing the response in a terrestrial detector to these synthetic responses provides a direct way to determine the main parameters of the supernova-neutrino energy-distribution.

description: Atrazine is the most commonly used herbicide worldwide in the agricultural system. The increased environmental concentration of the atrazine showed the toxic effects on the non-target living species. Biodegradation of the atrazine is possible with the bacterial systems. The present study investigated biodegradation potential of atrazine degrading bacteria and the impact of atrazine on environmental systems. Model of atrazine fate in ecological systems constructed using the cell designer. The used model further analyzed and simulated to know the biochemistry and physiology of the atrazine in different cellular networks. Topological analysis of the atrazine degradation confirmed the 289 nodes and 300 edges. Our results showed that the overall biomagnification of the atrazine in the different environmental systems. Atrazine is showing toxic effects on humans and plants, whereas degraded by the bacterial systems. To date, no one has analyzed the complete degradation and poisonous effects of the atrazine in the environment. Therefore, this study is useful for overall system biology based modeling and simulation analysis of atrazine in living systems. Communicated by Ramaswamy H. Sarma

description: We explicitly exhibit n-1 constants of motion for geodesics in the general D-dimensional Kerr-NUT-AdS rotating black hole spacetime, arising from contractions of even powers of the 2-form obtained by contracting the geodesic velocity with the dual of the contraction of the velocity with the (D-2)-dimensional Killing-Yano tensor. These constants of motion are functionally independent of each other and of the D-n+1 constants of motion that arise from the metric and the D-n = [(D+1)/2] Killing vectors, making a total of D independent constants of motion in all dimensions D. The Poisson brackets of all pairs of these D constants are zero, so geodesic motion in these spacetimes is completely integrable.

description: In this paper we discuss the interplay of quantum fluctuations and dissipation in uniform superconducting nanowires. We consider a phenomenological model with superconducting and normal components, and a finite equilibration rate between these two-fluids. We find that phase-slip dipoles proliferate in the wire, and decouple the two-fluids within its bulk. This implies that the the normal fluid only couples to the superconductor fluid through the leads at the edges of the wire, and the {\it local} dissipation is unimportant. Therefore, while long wires have a superconductor-metal transition tuned by local properties of the superconducting fluid, short wires have a transition when the {\it total} resistance is $R_{total}=R_Q=h/4e^2$.

Leukemia and bone marrow transplantation : personal meanings and perceptions of the illness experience
Creators: name: Richards, Debra C.
Publisher: name: University of British Columbia
Year: 2008

description: A non-probability, purposive sample was selected from the bone marrow transplant (BMT) directory of a North American transplant center to describe the personal meanings and perceptions of the illness experience of individuals who had been diagnosed with leukemia, and undergone BMT, and to explore and describe how the individuals' explanatory model of health and illness differs from the professional biomedical model of health care. A phenomenological approach guided the data collection process. Personal interviews with the four participants were conducted with the interview format and questions being based on Kleinman, Eisenberg and Good's (1978) model for eliciting a person’s explanatory model of health and illness. The data, comprised of verbatim transcripts of the audio-recorded interviews, and field notes of the researcher, were analyzed by employing the steps of phenomenological analysis as outlined by Patton (1991), and Giorgi (1985), which resulted in the identification of recurrent themes. Findings revealed that individuals perceive their illness in ways that differ from professionals. The participants perceived leukemia as a chronic illness rather than an acute disease. BMT, perceived as a life-saving - death-postponing treatment, possessed characteristics which led to personal and moral dilemmas. Participants viewed the cause of disease to be external to themselves, and beyond their control. The chronic implications of the illness were controlled for, and coped with by adopting altered definitions of normalcy and going through a process of re-learning. The study found that living with a life-threatening illness, although "successfully treated," took the meaning of uncertainty. Being faced with, and learning to live with a life-threatening illness was perceived as an opportunity for enrichment of life. The findings indicate the biomedical approach to healthcare is narrow in focus, and fails to consider the personal meanings and perceptions the illness experience hold for individuals who have been diagnosed with leukemia, and treated with BMT. For effective health care to be provided, and to reduce the differences and discrepancies between individuals and health care professionals, health care professionals must consider and incorporate the individual's explanatory model of health and illness into the health care plan.

description: We show that when the gravitational force is correctly calculated in dealing with the vertical hydrostatic equilibrium of black hole accretion disks, the relationship that is valid for geometrically thin disks, i.e., $c_s/Ω_K H =$ constant, where $c_s$ is the sound speed, $Ω_K$ is the Keplerian angular velocity, and $H$ is the half-thickness of the disk, does not hold for slim disks. More importantly, by adopting the correct vertical gravitational force in studies of thermal equilibrium solutions, we find that there exists a maximally possible accretion rate for each radius in the outer region of optically thick accretion flows, so that only the inner region of these flows can possibly take the form of slim disks, and strong outflows from the outer region are required to reduce the accretion rate in order for slim disks to be realized.

The proof is for the 5-dimensional case with or without resonance. In higher dimensions, the problem is open. Progresses are made by establishing a complete set of Melnikov-Arnold integrals in higher and infinite dimensions. The openness lies at the concrete computation of these Melnikov-Arnold integrals. New machineries introduced here into the topic of Arnold diffusion are the Darboux transformation and isospectral theory of integrable systems.

description: In this work we investigate the possibility to create cold Fr$\_2$, RbFr, and CsFr molecules through photoassociation of cold atoms. Potential curves, permanent and transition dipole moments for the Francium dimer and for the RbFr and RbCs molecules are determined for the first time. The Francium atom is modelled as a one valence electron moving in the field of the Fr$^+$ core, which is described by a new pseudopotential with averaged relativistic effects, and including effective core polarization potential. The molecular calculations are performed for both the ionic species Fr$\_2^+$, RbFr$^+$, CsFr$^+$ and the corresponding neutral, through the CIPSI quantum chemistry package where we used new extended gaussian basis sets for Rb, Cs, and Fr atoms. As no experimental data is available, we discuss our results by comparison with the Rb$\_2$, Cs$\_2$, and RbCs systems. The dipole moment of CsFr reveals an electron transfer yielding a Cs$^+$Fr$^-$ arrangement, while in all other mixed alkali pairs the electron is transferred towards the lighter species. Finally the perturbative treatment of the spin-orbit coupling at large distances predicts that in contrast with Rb$\_2$ and Cs$\_2$, no double-well excited potential should be present in Fr$\_2$, probably preventing an efficient formation of cold dimers via photoassociation of cold Francium atoms.

description: Neutrino-cooled hyperaccretion disks around stellar mass black holes are plausible candidates for the central engine of gamma-ray bursts. We calculate the one-dimensional structure and the annihilation luminosity of such disks. The neutrino optical depth is of crucial importance in determining the neutrino cooling rate and is in turn dependent on the electron fraction, the free nucleon fraction, and the electron degeneracy, with given density and temperature of the disk matter. We construct a bridging formula for the electron fraction that works for various neutrino optical depths, and give exact definitions for the free proton fraction and free neutron fraction. We show that the electron degeneracy has important effects in the sense that it enlarges the absorption optical depth for neutrinos, and it along with the neutronization processes favored by high temperature cause the electron fraction to drop to be below 0.1 in the inner region of the disk. The resulting neutrino annihilation luminosity is considerably reduced comparing with that obtained in previous works where the electron degeneracy was not considered and the electron fraction was simply taken to be 0.5, but it is still likely to be adequate for gamma-ray bursts, and it is ejected mainly from the inner region of the disk and has an anisotropic distribution.

As a criterion in the determination of the functional significance of a n-node subgraph, we propose an analytic method to measure the stability of the synchronous state (SSS) the subgraph displays. We show that, for undirected graphs, the SSS is correlated with the relative abundance, while in directed graphs the correlation exists only for some specific motifs.

Για την απάντηση των ερευνητικών ερωτημάτων η διπλωματική εργασία παραθέτει το υπάρχον εννοιολογικό και θεωρητικό πλαίσιο που περιβάλει τις κυρώσεις, με ορισμούς, ορολογία, διάκριση τους σε κατηγορίες κ.α., εξετάζει τις ιστορικές και τις σε εξέλιξη κυρώσεις από το Σ/Α και την Ε.Ε. δίνοντας παράλληλα ιδιαίτερη έμφαση στην περίπτωση της Ρωσικής Ομοσπονδίας.
description: The aim of the present thesis is to investigate if sanctions could be an effective instrument in international politics and so analyses all these issues which render sanction instrument effective or not. In addition, this thesis focus on European Union’s and third states’ sanction implementation against Russia Federation intending on the one hand to calculate the impact of sanctions in Russian economy, on the other hand to estimate if it is possible Russia to reappraise its foreign policy as a result of sanctions. Apart from the above-mentioned, we also examine the correlation between sanction effectiveness and the collaboration among international, regional organizations (U.N., E.U.) and states, as well as the flexibility and the advantages of E.U.’s sanctions decision making process in comparison with Security Council’s, in promoting international peace and security. In order to answer our research questions, we would refer to the existing conceptual and theoretical sanction framework by quoting definitions, terminology and categorisations of them. In addition, we will also examine both Security Council’s and E.U.’s terminated and active sanctions, giving emphasis in the case of Russian Federation.

description: Στα προβλήματα διάχυσης σε δίκτυα εκτός του βασικού προβλήματος της εύρεσης του χρόνου και της έκτασης της εξάπλωσης, έχουμε την πρακτική ανάγκη να λύσουμε το αντίστροφο πρόβλημα της εύρεσης της πηγής φήμης ή « ιού « δηλ. από πού ξεκίνησε η «μόλυνση» με την ευρύτερη έννοια του όρου . Για πρώτη φορά το αντίστροφο πρόβλημα αντιμετωπίστηκε το 2010-11 από τους Shah-Zaman με την εισαγωγή μιας νέας κεντρικότητας, της κεντρικότητας φήμης και ενός αλγορίθμου που την υλοποιεί. Στην παρούσα εργασία διερευνάται ο αλγόριθμος αυτός και η σχετική επεξεργασία για τον σωστό εντοπισμό της πηγής μέσω ενός εκτιμητή μέγιστης πιθανοφάνειας καθώς και προσομοιώσεις.
description: In the case of diffusion problems in networks apart from the basic problem of the detection and the extent of the spreading in time, we have to face the practical need to solve the inverse problem of the detection of the source of rumor or "infection" i.e. the problem from where the "infection" or rumor started. Shah-Zaman in 2010-11 addressed the inverse with the introduction of a new centrality index, the so called rumor centrality, and a related algorithm. In the present work we investigate the algorithm as well as the procedure for the correct source detection by an ML estimator with some simulations.

description: We report the discovery of strong soft X-ray emission lines and a hard continuum above 2 keV in the Narrow-Line Seyfert 1 galaxy Mrk 335 during an extremely low X-ray flux state. Mrk 335 was observed for 22 ks by XMM-Newton in July 2007 as a Target of Opportunity to examine it in its X-ray low-flux state, which was discovered with Swift. Long-term light curves suggest that this is the lowest flux state this AGN has ever been seen in. However, Mrk 335 is still sufficiently bright that its X-ray properties can be studied in detail. The X-ray continuum spectrum is very complex and requires several components to model. Statistically, partial covering and blurred reflection models work well. We confirm the presence of a strong narrow Fe line at 6.4 keV. High-resolution spectroscopy with the XMM-RGS reveals strong, soft X-ray emission lines not detected in previous, higher signal-to-noise, XMM-Newton observations, such as: highly ionized Fe lines, O VII, Ne IX and Mg XI lines. The optical/UV fluxes are similar to those previously measured with Swift. Optical spectroscopy taken in 2007 September do not show any changes to optical spectra obtained 8 years earlier.

description: We confront the predictions of different quintessence models with recent measurements of the luminosity distance from two sets of supernovae type Ia. In particular, we consider the 157 SNe Ia in the Gold dataset with z<1.7, and the more recent data containing 71 supernovae obtained by the Supernova Legacy Survey (SNLS) with z<1. We numerically solve the evolution equations for the Ratra-Peebles inverse power law model, the double exponential and the hyperbolic cosine quintessence models. We obtain confidence regions from the two datasets in the Ω_M-αand Ω_M-w_ϕplanes for the different models and compare their predictions with dark energy models with constant equation of state.

description: The general theme of this thesis falls within the scope of technologies and applications for "Smart Cities" and the specific implementation involves the case of publishing open data to a cartographic web platform. More specifically, open geospatial data supplied by the Municipality of Thessaloniki as part of ' Smart City ' initiative are presented in an interactive map. At first, we explained the concept of "Smart City" and how can this be operated within within the framework of a city. Important are the references to the effort to achieve smart cities. Then, we presented the concept of open data and the benefits resulting from the publication, the release and their utilization in various applications. Accordingly there is a general reference to cartographic visualization and in publishing of geospatial data via the Internet as well as in the respective technologies used in this purpose. Finally there’s a thorough walkthrough of implementing the aforementioned web based mapping platform and some use cases are presented .

description: (Abridged) Chandra and Hubble ACS observations of 11 early-type galaxies probe the low-mass X-ray binary (LMXB) - globular cluster (GC) connection. We explore the optical properties of 270 GCs with LMXBs and 6,488 GCs without LMXBs. More massive, redder, and more compact GCs are more likely to contain LMXBs. Unlike Galactic GCs, a large number of GCs with LMXBs have half-mass relaxation times > 2.5 Gyr. We fit the dependence of the expected number of LMXBs per GC, λ_t, on the GC mass M, color (g-z), and half-mass radius r_{h,cor}, and find that λ_t \propto M^{1.24\pm0.08} 10^{0.9^{+0.2}_{-0.1} (g-z)} r_{h,cor}^{-2.2^{+0.3}_{-0.4}}. Our fit rules out that the number of LMXBs per GC is linearly proportional to GC mass and that most GCs with high X-ray luminosities contain a single LMXB. The detailed dependence of λ_t on GC properties appears essentially equivalent to a dependence on the encounter rate Γ_h and the metallicity Z, λ_t \propto Γ_h^{0.82\pm0.05} Z^{0.39\pm0.07}. Our analysis provides strong evidence that dynamical formation and metallicity play the primary roles in determining the presence of an LMXB in extragalactic GCs. The shallower than linear dependence for our sample requires an explanation by theories of dynamical binary formation. The abundance dependence is consistent with a metallicity-dependent variation in the number o neutron stars and black holes per unit mass GC, effects from irradiation induced winds or suppression of magnetic braking in metal-poor stars.

description: We study a one-component quaternionic wave equation which is relativistically covariant. Bi-linear forms include a conserved 4-current and an antisymmetric second rank tensor. Waves propagate within the light-cone and there is a conserved quantity which looks like helicity. The principle of superposition is retained in a slightly altered manner. External potentials can be introduced in a way that allows for gauge invariance. There are some results for scattering theory and for two-particle wavefunctions as well as the beginnings of second quantization. However, we are unable to find a suitable Lagrangian or an energy-momentum tensor.

The value of business plays a determining role in the merges and takeovers. The combination of financial economic analysis and an effective valuation is necessary for drawing reliable conclusions. The purpose of this thesis is the study of business valuation methods, putting particular emphasis on the Discounted Free Cash Flow Method – DFCF. Moreover, the financial ratios required for a financial economic analysis are presented so as the final valuation to be as reliable as possible. Concluding, a practical application of the theoretical analysis has been conducted in AEIFOROS S.A. company which takes action in the field of recycling and processing of metals. More, specifically, a Business Plan with analysis SWOT, PEST and PORTER is used. Furthermore, a financial analysis based on financial ratios is applied and also the Discounted Free Cash Flow Method for the whole the company. The combination of all three analysis had led to a complete valuation.
CMB Anisotropies from Outflows in Lyman Break Galaxies

description: Thomson scattering of the Cosmic Microwave Background (CMB) on moving electrons in the outflows of Lyman Break Galaxies (LBGs) at redshifts 2-8 contributes to the small-scale CMB anisotropies. The net effect produced by each outflow depends on its level of deviation from spherical symmetry, caused either by an anisotropic energy injection from the nuclear starburst or quasar activity, or by an inhomogeneous intergalactic environment. We find that for plausible outflow parameters consistent with spectroscopic observations of LBGs, the induced CMB anisotropies on arcminute scales reach up to $\sim 1 μ$K, comparable to the level produced during the epoch of reionization.
