description: We extract the Boer-Mulders functions of valence and sea quarks in the proton from unpolarized $p+D$ Drell-Yan data measured by the FNAL E866 Collaboration. Using these Boer-Mulders functions, we calculate the $\cos 2 ϕ$ asymmetries in unpolarized $pp$ Drell-Yan processes, both for the FNAL E866/NuSea and the BNL Relativistic Heavy Ion Collider (RHIC) experiments. We also estimate the $\cos 2 ϕ$ asymmetries in the unpolarized $p\bar{p}$ Drell-Yan processes at GSI.

description: I exploit Martin’s (2016) proxy of the equity premium to examine the reasons behind the US stock market evolution during the COVID-19 pandemic. Based on Knox and Vissing-Jorgensen’s (2021) decomposition of unexpected stock returns, I present that changes in the short-term equity premium can explain 58%–65% of the stock market evolution. I further construct an index (CARS) to reveal households’ concerns about coronavirus using Google search as in Da et al. (2014). Results show that a standard deviation increase in CARS coincides with an increase of 7.05 basis points of contemporary change in the 1-month equity premium. My findings indicate that policymakers and investors should pay attention to aggregate market fears about the pandemic or other crisis events in the future. Additionally, the equity premium from 1996 to 2020 illustrates that the US stock market has different regimes during crisis and non-crisis periods, and the term structure of equity premium is procyclical.

description: We present new infrared spectra of the T8 brown dwarf 2MASS J04151954-0935066: 2.9-4.1 micron spectra obtained with the Infrared Camera and Spectrograph on the Subaru Telescope, and 5.2-14.5 micron spectra obtained with the Infrared Spectrograph on the Spitzer Space Telescope. We use these data and models to determine an accurate bolometric luminosity of log L_bol/L_sun=-5.67 and to constrain the effective temperature, gravity, mass and age to 725-775K, log g=5.00-5.37, M=33-58 M_Jupiter and age=3-10Gyr. We perform the same analysis using published 0.6-15 micron spectra for the T7.5 dwarf 2MASS J12171110-0311131, for which we find a metal-rich composition ([Fe/H]~0.3) and log L_bol/L_sun=-5.31, T_eff=850-950K, log g=4.80-5.42, M=25-66M_Jupiter and age=1-10Gyr. These luminosities and effective temperatures straddle those determined with the same method and models for Gl 570D by Saumon et al. (2006) and make 2MASS J04151954-0935066 the coolest and least luminous T dwarf with well-determined properties. We find that synthetic spectra generated by the models reproduce the observed red through mid-infrared spectra of 2MASS J04151954-0935066 and 2MASS J12171110-0311131 very well, except for known discrepancies which are most likely due to the incomplete CH4 opacities. Both objects show evidence of departures from strict chemical equilibrium and we discuss this result in the context of other late T dwarfs where disequilibrium phenomena have been observed.

description: Radars and cameras are mature, cost-effective, and robust sensors and have been widely used in the perception stack of mass-produced autonomous driving systems. Due to their complementary properties, outputs from radar detection (radar pins) and camera perception (2D bounding boxes) are usually fused to generate the best perception results. The key to successful radar-camera fusion is the accurate data association. The challenges in the radar-camera association can be attributed to the complexity of driving scenes, the noisy and sparse nature of radar measurements, and the depth ambiguity from 2D bounding boxes. Traditional rule-based association methods are susceptible to performance degradation in challenging scenarios and failure in corner cases. In this study, we propose to address radar-camera association via deep representation learning, to explore feature-level interaction and global reasoning. Additionally, we design a loss sampling mechanism and an innovative ordinal loss to overcome the difficulty of imperfect labeling and to enforce critical human-like reasoning. Despite being trained with noisy labels generated by a rule-based algorithm, our proposed method achieves a performance of 92.2% F1 score, which is 11.6% higher than the rule-based teacher. Moreover, this data-driven method also lends itself to continuous improvement via corner case mining.

description: We study the phase diagram of two-dimensional Bose-Fermi mixtures of ultracold atoms on a triangular optical lattice, in the limit when the velocity of bosonic condensate fluctuations is much larger than the Fermi velocity. We contrast this work with our previous results for a square lattice system in Phys. Rev. Lett. {\bf 97}, 030601 (2006). Using functional renormalization group techniques we show that the phase diagrams for a triangular lattice contain exotic superconducting phases. For spin-1/2 fermions on an isotropic lattice we find a competition of $s$-, $p$-, extended $d$-, and $f$-wave symmetry, as well as antiferromagnetic order. For an anisotropic lattice, we further find an extended p-wave phase. A Bose-Fermi mixture with spinless fermions on an isotropic lattice shows a competition between $p$- and $f$-wave symmetry. These phases can be traced back to the geometric shapes of the Fermi surfaces in various regimes, as well as the intrinsic frustration of a triangular lattice.

description: The purpose of this dissertation is to investigate the impact of differentiated instruction with technology on EFL Greek learners’ (A1-A2 level) reading and listening scores in the context of a private English school. One hundred students - aged 9 to 11 years - participated in the research, half of whom received differentiated instruction assisted with technology and constituted the experimental group and the other half, called control group, received traditional, non–differentiated instruction without integrating technology. Moreover, data were collected through a needs analysis questionnaire, an interest inventory, a learning style inventory, a pre-, while-, and post- listening and reading test. Findings of the study showed that the experimental group outperformed the control group in terms of their reading and listening scores

description: We present new radio observations of the binary neutron star merger GW170817 carried out with the Karl G. Jansky Very large Array (VLA) more than 3\,yrs after the merger. Our combined dataset is derived by co-adding more than $\approx32$\,hours of VLA time on-source, and as such provides the deepest combined observation (rms sensitivity $\approx 0.99\,μ$Jy) of the GW170817 field obtained to date at 3\,GHz. We find no evidence for a late-time radio re-brightening at a mean epoch of $t\approx 1200$\,d since merger, in contrast to a $\approx 2.1\,σ$ excess observed at X-ray wavelengths at the same mean epoch. Our measurements agree with expectations from the post-peak decay of the radio afterglow of the GW170817 structured jet. Using these results, we constrain the parameter space of models that predict a late-time radio re-brightening possibly arising from the high-velocity tail of the GW170817 kilonova ejecta, which would dominate the radio and X-ray emission years after the merger (once the structured jet afterglow fades below detection level). Our results point to a steep energy-speed distribution of the kilonova ejecta (with energy-velocity power law index $α\gtrsim 5$). We suggest possible implications of our radio analysis, when combined with the recent tentative evidence for a late-time re-brightening in the X-rays, and highlight the need for continued radio-to-X-ray monitoring to test different scenarios.

Five years of searches for point sources of astrophysical neutrinos with the AMANDA-II neutrino telescope

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We report the results of a five-year survey of the northern sky to search for point sources of high energy neutrinos. The search was performed on the data collected with the AMANDA-II neutrino telescope in the years 2000 to 2004, with a live-time of 1001 days. The sample of selected events consists of 4282 upward going muon tracks with high reconstruction quality and an energy larger than about 100 GeV. We found no indication of point sources of neutrinos and set 90% confidence level flux upper limits for an all-sky search and also for a catalog of 32 selected sources. For the all-sky search, our average (over declination and right ascension) experimentally observed upper limit Φ^{0}=(E/TeV)^γdΦ/dE to a point source flux of muon and tau neutrino (detected as muons arising from taus) is Φ_{ν_μ}^{0} + Φ_{ν_τ}^{0} = 11.1 x 10^{-11} TeV^-1 cm^-2 s^-1, in the energy range between 1.6 TeV and 2.5 PeV for a flavor ratio Φ_{ν_μ}^{0} / Φ_{ν_τ}^{0}= 1 and assuming a spectral index γ=2. It should be noticed that this is the first time we set upper limits to the flux of muon and tau neutrinos. In previous papers we provided muon neutrino upper limits only neglecting the sensitivity to a signal from tau neutrinos, which improves the limits by 10% to 16%. The value of the average upper limit presented in this work corresponds to twice the limit on the muon neutrino flux Φ_{ν_μ}^{0} = 5.5 \cdot 10^{-11} TeV^-1 cm^-2 s^-1. A stacking analysis for preselected active galactic nuclei and a search based on the angular separation of the events were also performed. We report the most stringent flux upper limits to date, including the results of a detailed assessment of systematic uncertainties.

description: The metric of a spacetime can be greatly simplified if the spacetime is circular. We prove that in generic effective theories of gravity, the spacetime of a stationary, axisymmetric and asymptotically flat solution must be circular if the solution can be obtained perturbatively from a solution in the general relativity limit. This result applies to a broad class of gravitational theories that include arbitrary scalars and vectors in their light sector, so long as their nonstandard kinetic terms and nonmininal couplings to gravity are treated perturbatively.

description: Rhombohedral $N = 3$ trilayer graphene on hexagonal boron nitride (TLG/BN) hosts gate-tunable, valley-contrasting, nearly flat topological bands that can trigger spontaneous quantum Hall phases under appropriate conditions of the valley and spin polarization. Recent experiments have shown signatures of C = 2 valley Chern bands at 1/4 hole filling, in contrast to the predicted value of C = 3. We discuss the low-energy model for rhombohedral N-layer graphene (N = 1, 2, 3) aligned with hexagonal boron nitride (hBN) subject to off-diagonal moire vector potential terms that can alter the valley Chern numbers. Our analysis suggests that topological phase transitions of the flat bands can be triggered by pseudomagnetic vector field potentials associated to moire strain patterns, and that a nematic order with broken rotational symmetry can lead to valley Chern numbers that are in agreement with recent Hall conductivity observations.

description: We study the evolution of six exoplanetary systems with the stellar evolutionary code MESA and conclude that they will likely spin-up the envelope of their parent stars on the red giant branch (RGB) or later on the asymptotic giant branch (AGB) to the degree that the mass loss process might become non-spherical. We choose six observed exoplanetary systems where the semi-major axis is ~1-2AU, and use the binary mode of MESA to follow the evolution of the systems. In four systems the star engulfs the planet on the RGB, and in two systems on the AGB, and the systems enter a common envelope evolution (CEE). In two systems where the exoplanet masses are Mp~10MJ, where MJ is Jupiter mass, the planet spins-up the envelope to about 10% of the break-up velocity. Such envelopes are likely to have significant non-spherical mass loss geometry. In the other four systems where Mp~MJ the planet spins-up the envelope to values of ~1-2% of break-up velocity. Magnetic activity in the envelope that influences dust formation might lead to a small departure from spherical mass loss even in these cases. In the two cases of CEE on the AGB the planet deposits energy to the envelope that amounts to >10% of the envelope binding energy. We expect this to cause a non-spherical mass loss that will shape an elliptical planetary nebula in each case.

description: Consider a physical system for which a mathematically rigorous geometric quantization procedure exists. Now subject the system to a finite set of irreducible first class (bosonic) constraints. It is shown that there is a mathematically rigorous BRST quantization of the constrained system whose cohomology at ghost number zero recovers the constrained quantum states. Moreover this space of constrained states has a well-defined Hilbert space structure inherited from that of the original system. Treatments of these ideas in the Physics literature are more general but suffer from having states with infinite or zero "norms" and thus are not admissible as states. Also the BRST operator for many systems require regularization to be well-defined. In our more restricted context we show that our treatment does not suffer from any of these difficulties. This work was submitted for publication March 21,2006.

description: Background: Coronavirus disease 2019 (COVID-19) can place an immense psychological strain on the infected patient. The psychological distress can linger after the initial recovery from the infection. Objective: This study aimed to evaluate the prevalence and predictors of provisional post-traumatic stress disorder (PTSD) in patients with cured COVID-2019. Methods: The baseline survey was conducted from 10 to 25 February 2020 in patients with COVID-19 in a designated hospital. Demographic and clinical characteristics were acquired, and depression and anxiety levels were assessed, using the 9-item Patient Health Questionnaire and 7-item Generalized Anxiety Disorder scale, respectively. A follow-up survey was conducted 1 month post-discharge. PTSD symptoms were measured by the Impact of Event Scale-6 (IES-6) and patients’ perception of supportive care during hospitalization was investigated using a self-developed questionnaire. Results: In total, 114 patients completed both the baseline and follow-up surveys. Of these, 41 (36.0%) met the cut-off score for provisional PTSD diagnosis according to the IES-6. Female gender [odds ratio (OR) = 4.69, 95% confidence interval (CI) 1.54–14.37], educational level of high school or below (OR = 15.49, 95% CI 1.13–212.71), higher anxiety levels (OR = 1.34, 95% CI 1.12–1.61) and lower perceptions of emotional support during hospitalization (OR = 0.41, 95% CI 0.17–0.96) predicted a higher risk for provisional PTSD. Conclusions: PTSD is commonly seen in patients with COVID-19 1 month post-discharge. Female patients, and patients with lower educational levels, higher anxiety levels and lower perceptions of emotional support during hospitalization may be more likely to develop PTSD in the near future. Enhancing emotional support during hospitalization could help to prevent PTSD in patients with COVID-19. More than one-third ofpatients met the diagnostic criteria of probable PTSD 1 month post-discharge.Providing timely emotional support during hospitaliza-tion may be one of the key measures for preventing PTSD in patients with COVID-19.

description: An experiment to study the exchange processes within and above an extensive coniferous forest of Douglas-fir trees was conducted on Vancouver Island during a two-week rainless period in July and August 1990. The stand, which was planted in 1962, thinned and pruned uniformly in 1988, had a (projected) leaf area index of 5.4 and a height of h = 16.7 m. The experimental site was located on a 5° gentle slope. The primary instrumentation included two eddy correlation units which were operated in the daytime to measure the fluctuations in the three velocity components, air temperature and water vapour density. One unit was mounted permanently at a height of 23.0 m (z/h = 1.38) and the other at various heights of (z/h in brackets) 2.0 (0.12), 7.0 (0.42), 10.0 (0.60), and 16.7 m (1.00) with two to three 8-hour periods of measurement at each level. Profiles of wind speed and air temperature were measured continuously during the experimental period at heights of 0.9, 2.0, 4.6, 7.0, 10.0, 12.7, 16.7 and 23.0 m using sensitive cup anemometers and fine wire thermocouples, respectively. Radiation regimes and air humidity were measured both above and beneath the overstory of the stand. The vertical structure of the stand affected, to a great extent, the vertical distributions of the velocity statistics (wind speed, variance, turbulence intensity, Reynolds stress, skewness and kurtosis), air temperature, sensible and latent heat fluxes. The effect was also evident in the quadrant representation of the fluxes of momentum, sensible heat and water vapour. Negative Reynolds stress persistently occurred at the lower heights of the stand (z/h = 0.12 and 0.42). The negative values were related to the local wind speed gradients and it is believed that the longitudinal pressure gradient due to land-sea/upslope-downslope circulations was the main factor responsible for the upward transport of the momentum at these heights. Energy budget was examined both above and beneath the overstory of the stand. The sum of sensible and latent heat fluxes above the stand accounted for, on average, 83% of the available energy flux. Beneath the overstory, the corresponding figure was 74%. On some days, energy budget closure was far better than on others. [more abstract]

description: Recent data, including the three--year WMAP data, the full 2dF galaxy power spectrum and the first--year data of the Supernova Legacy Survey, are used to constrain model parameters in quintessence cosmologies. In particular, we discuss the inverse power--law (RP) and SUGRA potentials and compare parameter constraints with those for LCDM. Both potentials fit current observations with a goodness of fit comparable or better than LCDM. The constraints on the energy scale Lambda_DE appearing in both potential expressions are however different. For RP, only energy scales around the cosmological constant limit are allowed, making the allowed models quite similar to LCDM. For SUGRA, Lambda_DE values approximately up to Electroweak energy scale are still allowed, while other parameter intervals are slightly but significantly displaced. In particular a value of the primeval spectral index n_s = 1 is still allowed at the 95% c.l., and this can have an impact on constraints on possible inflationary potentials.

description: We investigate the impact of 3D hydrodynamical model atmospheres of red giant stars at different metallicities on the formation of spectral lines of a number of ions and molecules. We carry out realistic 3D simulations of surface convection in red giant stars with varying stellar parameters. We use the simulations as time-dependent hydrodynamical model stellar atmospheres to compute atomic (Li, O, Na, Mg, Ca, Fe) and molecular (CH, NH, OH) spectral lines under the assumption of local thermodynamic equilibrium (LTE). We compare the line strengths computed in 3D with the results of analogous line formation calculations for 1D, hydrostatic, plane-parallel MARCS model atmospheres in order to estimate the impact of 3D models on the derivation of elemental abundances. The temperature and density inhomogeneities and correlated velocities in 3D models, as well as the differences between the 1D and mean 3D structures significantly affect the predicted line strengths. Under the assumption of LTE, the low atmospheric temperatures of very metal-poor 3D model atmospheres cause the lines from neutral species and molecules to appear stronger than in 1D. Therefore, elemental abundances derived from these lines using 3D models are significantly lower than according to 1D analyses. Differences between 3D and 1D abundances of C, N, and O derived from CH, NH, and OH weak low-excitation lines are found to be in the range -0.5 dex to -1.0 dex for the the red giant stars at [Fe/H]=-3 considered here. At this metallicity, large negative corrections (about -0.8 dex) are also found for weak low-excitation Fe I lines. We caution, however, that departures from LTE might be significant for these and other elements and comparable to the effects due to stellar granulation.

Incorporating semantic integrity constraints in a database schema
Creators: name: Yang, Heng-Li
Publisher: name: University of British Columbia
Year: 2008

description: A database schema should consist of structures and semantic integrity constraints. Se mantic integrity constraints (SICs) are invariant restrictions on the static states of the stored data and the state transitions caused by the primitive operations: insertion, dele tion, or update. Traditionally, database design has been carried out on an ad hoc basis and focuses on structure and efficiency. Although the E-R model is the popular concep tual modelling tool, it contains few inherent SICs. Also, although the relational database model is the popular logical data model, a relational database in fourth or fifth normal form may still represent little of the data semantics. Most integrity checking is distributed to the application programs or transactions. This approach to enforcing integrity via the application software causes a number of problems. Recently, a number of systems have been developed for assisting the database design process. However, only a few of those systems try to help a database designer incorporate SICs in a database schema. Furthermore, current SIC representation languages in the literature cannot be used to represent precisely the necessary features for specifying declarative and operational semantics of a SIC, and no modelling tool is available to incorporate SICs. This research solves the above problems by presenting two models and one subsystem. The E-R-SIC model is a comprehensive modelling tool for helping a database designer in corporate SICs in a database schema. It is application domain-independent and suitable for implementation as part of an automated database design system. The SIC Repre sentation model is used to represent precisely these SICs. The SIC elicitation subsystem would verify these general SICs to a certain extent, decompose them into sub-SICs if necessary, and transform them into corresponding ones in the relational model. A database designer using these two modelling tools can describe more data semantics than with the widely used relational model. The proposed SIC elicitation subsystem can provide more modelling assistance for him (her) than current automated database design systems.

description: Η παρούσα μεταπτυχιακή εργασία πραγματεύεται τη μελέτη της χωροταξικής και οικιστικής όψης που ανέπτυξαν οι αποικίες της Μιλήτου στις χερσονήσους της Κριμαίας και του Ταμάν κατά το χρονικό πλαίσιο της Αρχαϊκής και Κλασικής Εποχής. Αρχικά, εξετάζονται σε γενικές γραμμές τα χαρακτηριστικά της αποικιακής δραστηριότητας που ανέλαβε η ιωνική πόλη της Μιλήτου, το χρονολογικό της πλαίσιο και τα κίνητρά της. Από την έρευνα για τον ιωνικό αποικισμό στον βόρειο Εύξεινο Πόντο προέκυψαν έντεκα εγκαταστάσεις στη χερσόνησο της Κριμαίας και πέντε στη χερσόνησο του Ταμαν. Στο δεύτερο κεφάλαιο η κάθε εγκατάσταση ξεχωριστά αποτελεί αντικείμενο βιβλιογραφικής μελέτης. Σε κάθε περίπτωση αναφέρονται εισαγωγικά οι γενικές πληροφορίες για την αποικία και στη συνέχεια μελετώνται τα αρχαιολογικά δεδομένα. Στη συνέχεια, εξετάζονται τα κατάλοιπα των ιδιωτικών κτισμάτων, οι αρχιτεκτονικές του ιδιαιτερότητες και τα κτίσματα του δημόσιου χώρου με λατρευτική λειτουργία και πολιτική σημασία. Επίσης, συμπεριλαμβάνονται στη μελέτη οι οχυρώσεις των πόλεων και οι θέσεις ενταφιασμού. Τέλος, στο τρίτο κεφάλαιο εξετάζονται συνθετικά τα στοιχεία που προέκυψαν, ενώ αναγνωρίζονται και τα κοινά χαρακτηριστικά πάνω στα οποία αναπτύχθηκαν οι αποικίες. Προσδιορίζοντάς τα, εξετάζεται ο βαθμός εξάρτησης της αποικίας από τη μητρόπολή της και η μετεξέλιξή της κάτω από τις νέες γεωγραφικές και κοινωνικές συνθήκες
description: This master thesis deals with the study of the spatial and residential aspects developed by the Milesian colonies in the peninsulas of Crimea and Taman during the archaic and classical era. Initially, the general characteristics of the colonial activity undertaken by the Ionian city of Miletus, its chronological context and its motives are considered. From the survey of the Ionic colonization in the northern Black Sea eleven facilities have emerged on the Crimean peninsula and five on the Taman peninsula. In the second chapter, each settlement individually is a subject of bibliographic study. In each case, the general information about the colony is quoted and then the archaeological data is studied. Afterwards, the residues of private buildings, their architectural particularities, and buildings of public space with cult and political importance are examined. In addition, city fortifications and burial sites are included in the study. Finally, the elements that have emerged are examined in the third chapter, by deploying synthesis as a method, while the common features of the colonies’ development are identified. By specifying them, the extent of dependence of the colony on its metropolis and its transformation under the new geographical and social conditions is identified

description: Οι δυσκολίες που συναντούν πολλοί μαθητές κατά τη διάρκεια της σχολικής τους φοίτησης φέρνουν στο επίκεντρο μεταξύ άλλων, τη σχέση που αναπτύσσεται μεταξύ δασκάλου και μαθητή, τη διαδικασία μέσω της οποίας επιτυγχάνεται η μάθηση και τα συστατικά της στοιχεία. Συνακόλουθα η σχολική αποτυχία που βιώνουν πολλοί μαθητές συνιστά ένα ζήτημα που απασχολεί όχι μόνο το εκπαιδευτικό πλαίσιο εντός του οποίου εντάσσεται αλλά και την ευρύτερη κοινωνία, εξαιτίας των επιπτώσεων που αυτή επιφέρει στη μετέπειτα ζωή του παιδιού. Στα πλαίσια της παρούσας εργασίας επιχειρείται μέσω μιας ψυχοδυναμικής οπτικής που εμπνέεται από την ψυχαναλυτική θεωρία, η προσέγγιση τόσο της μάθησης όσο και της σχολικής αποτυχίας, με αποτέλεσμα να αναδεικνύονται η συναισθηματική συνιστώσα της μαθησιακής διαδικασίας και η ψυχική επένδυση της αποτυχίας ως μια εναλλακτική θεώρηση για την βαθύτερη κατανόηση, ερμηνεία και αντιμετώπιση των δυσκολιών στη μάθηση και της σχολικής αποτυχίας
description: The difficulties encountered by many students during their schooling bring out among others the relationship that is being developed between teacher and student, the components of learning and the process through which is achieved. Consequently, the school failure experienced by many students is an issue that concerns not only the educational context in which it belongs, but also the wider society, due to its impact on the later life of the child. In the context of this paper, an approach of both learning and school failure it is attempted, through a psychodynamic view, inspired by the psychoanalytic theory. As a consequence, the emotional component of the learning process and the psychological investment of failure are emerging as an alternative view for deeper understanding, interpretation and coping with learning difficulties and school failure

We claim that such an effect is related to the super--Poynting vector, in a similar way as the existence of the electromagnetic Poynting vector is related to the vorticity in stationary electrovacum spacetimes.

description: Understanding how the electron spin is coupled to orbital degrees of freedom, such as a valley degree of freedom in solid-state systems is central to applications in spin-based electronics and quantum computation. Recent developments in the preparation of electrostatically-confined quantum dots in gapped bilayer graphene (BLG) enables to study the low-energy single-electron spectra in BLG quantum dots, which is crucial for potential spin and spin-valley qubit operations. Here, we present the observation of the spin-valley coupling in a bilayer graphene quantum dot in the single-electron regime. By making use of a highly-tunable double quantum dot device we achieve an energy resolution allowing us to resolve the lifting of the fourfold spin and valley degeneracy by a Kane-Mele type spin-orbit coupling of $\approx 65~μ$eV. Also, we find an upper limit of a potentially disorder-induced mixing of the $K$ and $K'$ states below $20~μ$eV.

description: Marchenko methods are based on integral representations which express Green's functions for virtual sources and/or receivers in the subsurface in terms of the reflection response at the surface. An underlying assumption is that inside the medium the wave field can be decomposed into downgoing and upgoing waves and that evanescent waves can be neglected. We present a new derivation of Green's function representations which circumvents these assumptions, both for the acoustic and the elastodynamic situation. These representations form the basis for research into new Marchenko methods which have the potential to handle refracted and evanescent waves and to more accurately image steeply dipping reflectors.

description: Η παρούσα εργασία εξετάζει τις διαθρησκειακές πρωτοβουλίες διαλόγου των μουσουλμάνων με τους χριστιανούς σε τέσσερις επιλεγμένες χώρες της Μέσης Ανατολής. Οι χώρες με τις οποίες ασχολείται η έρευνα είναι η Ιορδανία, ο Λίβανος, το Κατάρ και το Ιράν. Στην εργασία επιχειρείται ακόμα η εξέταση των εννοιών της πολυπολιτισμικότητας και της θρησκευτικής ετερότητας ως απαραίτητα στοιχεία για να υπάρχει επικοινωνία μεταξύ των θρησκειών. Στη συνέχεια εξετάζονται τα γενικά χαρακτηριστικά του διαθρησκειακού διαλόγου, και συνοπτικά η πορεία και η εξέλιξη των προσπαθειών του Οικουμενικού Πατριαρχείου και του Παγκοσμίου Συμβουλίου Εκκλησιών όσον αφορά το διαθρησκειακό διάλογο με το Ισλάμ, προκειμένου να προσεγγίσουμε τα βήματα που ήδη έχουν πραγματοποιηθεί στον τομέα αυτό και έτσι να σχηματίσουμε μία όσο το δυνατόν πληρέστερη εικόνα για το θέμα. Στόχος της εργασίας είναι η ανάδειξη του διαθρησκειακού διαλόγου από τους μουσουλμάνους της Μέσης Ανατολής ως μέσο για την προώθηση της ειρήνης, της συνεργασίας, της συμφιλίωσης, ώστε κάθε αναγνώστης να κατανοήσει ότι οι μουσουλμάνοι συμβάλλουν για να προωθήσουν σημαντικές αξίες της ζωής και δεν κυριαρχούνται όλοι από θρησκευτικούς φανατισμούς και μισαλλοδοξίες
description: This paper examines the interreligious initiatives of a dialogue between Muslims and Christians in four selected Middle Eastern countries. The countries under investigation are Jordan, Lebanon, Qatar and Iran. The thesis also attempts to examine the concepts of multiculturalism and religious diversity as essential elements for communication between the two religions. The general characteristics of the interreligious dialogue are discussed. The course and evolution of the efforts of the Ecumenical Patriarchate and the World Council of Churches regarding the interfaith dialogue with Islam, are briefly discussed as well, in order to approach the steps already taken in this field and thus to form a fuller picture of the issue. The aim of the work is to highlight the interreligious dialogue by the Middle East Muslims as a means of promoting peace, co-operation and reconciliation so that every reader understands that Muslims contribute to the promotion of important values of life and are not all dominated by religious fanaticism and intolerance
