description: Many late time approaches for the solution of the Hubble tension use late time smooth deformations of the Hubble expansion rate $H(z)$ of the Planck18/$Λ$CDM best fit to match the locally measured value of $H_0$ while effectively keeping the comoving distance to the last scattering surface and $Ω_{0m} h^2$ fixed to maintain consistency with Planck CMB measurements. A well known problem of these approaches is that they worsen the fit to low $z$ distance probes. Here we show that another problem of these approaches is that they worsen the level of the $Ω_{0m}-σ_8$ growth tension. We use the generic class of CPL parametrizations corresponding to evolving dark energy equation of state parameter $w(z)=w_0+w_1\frac{z}{1+z}$ with local measurements $H_0$ prior and identify the pairs $(w_0, w_1)$ that satisfy this condition. This is a generic class of smooth deformations of $H(z)$ that are designed to address the Hubble tension. We show that for these models the growth tension between dynamical probe data and CMB constraints is worse than the corresponding tension of the standard Planck18/$Λ$CDM model. We justify this feature using a full numerical solution of the growth equation and fit to the data, as well as by using an approximate analytic approach. The problem does not affect recent proposed solutions of the Hubble crisis involving a SnIa intrinsic luminosity transition at $z_t\simeq 0.01$.

description: In this paper, we revisit topological-like features in the extended Temperley--Lieb diagrammatical representation for quantum circuits including the teleportation, dense coding and entanglement swapping. We perform these quantum circuits and derive characteristic equations for them with the help of topological-like operations. Furthermore, we comment on known diagrammatical approaches to quantum information phenomena from the perspectives of both tensor categories and topological quantum field theories. Moreover, we remark on the proposal for categorical quantum physics and information to be described by dagger ribbon categories.

description: Μια αρκετά διαδεδομένη άποψη στο χώρο της ψυχογλωσσολογίας είναι ότι το νοητικό λεξικό της ξένης γλώσσας είναι ποιοτικά διαφορετικό - περισσότερο φωνολογικά προσανατολισμένο και με πιο χαλαρούς δεσμούς - από το αντίστοιχο της μητρικής. Αυτή η διατριβή επιχειρεί να αμφισβητήσει την παραπάνω άποψη παρουσιάζοντας τα δεδομένα μιας έρευνας που πραγματοποιήθηκε στο Αγγλικό Τμήμα του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης. Τα αποτελέσματα δείχνουν ότι ο τρόπος με τον οποίο γίνεται η επεξεργασία των λέξεων δε βασίζεται τόσο στο είδος της γλώσσας (μητρικής ή ξένης) της οποίας είναι δείγματα, όσο στο βαθμό δυσκολίας της εκάστοτε λεξικής απόπειρας
description: A fairly widely held view in psycholinguistics is that the second language mental lexicon is more "phonological" than the first language lexicon, namely, that a qualitative difference exists between the two lexicons. In this study word association test data together with C-test data elecited from Greek advanced learners of English are presented which challenge the above view. The findings seem to suggest that the way words are processed is not so much related to the status of the language (first or second) to which they belong, but rather it depends on the level of familiarity of native speakers or learners with particular words at a particular time

description: Special problems were encountered in some areas in Northern France where the high speed railways (TGV Nord) crossed some loess deposits that appeared to be specially sensitive to change in water content and susceptible to collapse. Numerous sinkholes appeared along some sections of the line following wet climatic periods. After a general geological and geotechnical presentation of loess deposits and collapse susceptibility, in which some tools of the mechanics of unsaturated soils are reconsidered with special application to loess collapsibility, this paper describes the results of a geotechnical study carried out on block samples of intact loess. Collapse susceptibility is examined in the light of microstructure observation. The dependence of collapse to water content changes is examined and the validity of various existing collapse criteria is investigated.
Η Μητρόπολις και ο ελληνισμός Σηλυβρίας

description: Η Μητρόπολη Σηλυβρίας της Ανατολικής Θράκης, ως εκκλησιαστική επαρχία του Οικουμενικού Πατριαρχείου από τον 6ο αιώνα παρουσιάζει θρησκευτικό, κοινωνικό και πολιτιστικό έργο μέχρι τον Οκτώβριο του 1922. Αξιόλογοι μητροπολίτες, όπως ο Καλλίνικος (1799), ο Παϊσιος (1817), ο Διονύσιος (1900), κ.ά., φρόντισαν για τη διατήρηση της ελληνικής συνείδησης. Την περίοδο της Τουρκοκρατίας, αλλά και της Βουλγαρικής Εξαρχίας(1870), ο ελληνισμός χάρη στις εκκλησίες, στα εκπαιδευτικά ιδρύματα και στους συλλόγους αντιστάθηκε σθεναρά διατηρώντας την εθνικοθρησκευτική του φυσιογνωμία. Ονομαστά εκπαιδευτικά ιδρύματα, όπως τα "Αρχιγένεια" και σωματεία, όπως ο "Αγιος Σπυρίδων" (1879), συνέβαλαν στην πνευματική και πολιτιστική ανύψωση της περιοχής και συντήρησαν το εθνικό φρόνημα των ελληνικών κοινοτήτων. Κορυφαίες προσωπικότητες του Νέου Ελληνισμού, λόγιοι και εθνικοί ευεργέτες, όπως ο Νεκτάριος Κεφαλάς (1889), ο Σωφρόνιος Σταμούλης (1875), ο Σαράντης Αρχιγένης (1809), κ.ά., διακρίθηκαν για την εκπαιδευτική και εθνική τους δράση. Ο Ελληνισμός της Ανατολικής Θράκης το 1922 εγκατέλειψε τις πατρογονικές του εστίες και εγκαταστάθηκε στην Ελλάδα συνεχίζοντας την μακραίωνη παράδοση των προγόνων του.
description: The Metropolis of Silyvria in Eastern Thrace as Church perfecture of the Ecumenical Patriarchate since the 6th century has produced religious, social and cultural work till October 1922. Notable Metropolites such as Kallinikos (1799), Paisios (1817), Dionysios (1900), etc., looked to the preservation of the Greek conscience. During the hard periods of the Turkish domination and Bulgarian exarchate (1870), the Greek nation managed to keep their national and religious physiognomy alive, by putting a sturdy resistance, thanks to the churches, the educational institutions and some associations. Renowned educational institutions, such as "Archigenia" and associations such as "Saint Spyridon" (1879), contributed to the spiritual and cultural raising of the region and preserved the national conviction of the Greek commities. Top personalities of the new Greek nation, scholars and national benefactors, like Nektarios Kefalas (1889), Sofronios Stamoulis (1875), Sarandis Archigenis (1809) and others, stood out not only for their educational but also their national activity. In 1922, the Greeks of Eastern Thrace abandoned their ancestral homes and set up house in Greece keeping up their fore fathers tradition of many centuries.

description: Quantum gravitational effects in loop quantum cosmology lead to a resolution of the initial singularity and have the potential to solve the horizon problem and generate a quasi scale-invariant spectrum of density fluctuations. We consider loop modifications to the behavior of the inverse scale factor below a critical scale in closed models and assume a purely thermal origin for the fluctuations. We show that the no-go results for scale invariance in classical thermal models can be evaded even if we just consider modifications to the background (zeroth order) gravitational dynamics. Since a complete and systematic treatment of the perturbed Einstein equations in loop cosmology is still lacking, we simply parameterize their expected modifications. These change quantitatively, but not qualitatively, our conclusions. We thus urge the community to more fully work out this complex aspect of loop cosmology, since the full picture would not only fix the free parameters of the theory, but also provide a model for a non-inflationary, thermal origin for the structures of the Universe.

description: We discuss recent work on the static and dynamical properties of the asymmetric exclusion process, generalized to include the effect of disorder. We study in turn: random disorder in the properties of particles; disorder in the spatial distribution of transition rates, both with a single easy direction and with random reversals of the easy direction; dynamical disorder, where particles move in a disordered landscape which itself evolves in time. In every case, the system exhibits phase separation; in some cases, it is of an unusual sort. The time-dependent properties of density fluctuations are in accord with the kinematic wave criterion that the dynamical universality class is unaffected by disorder if the kinematic wave velocity is nonzero.

The effects of sleep quality on cognition in multiple sclerosis : a longitudinal pilot study
Creators: name: Fraser, CJ
Publisher: name: University of Tasmania
Year: 2024

description: Multiple Sclerosis (MS) is a debilitating disease which can negatively impact the cognitive functioning of people with Multiple Sclerosis (pwMS). Recently, sleep quality has emerged as a possible factor in MS. Observed relationships between sleep quality and cognition in research suggests that poor sleep quality may negatively impact cognition in pwMS. Cross-sectional research has associated poor subjective sleep quality with objective cognitive difficulties in working memory and spatial memory. While this relationship has been examined cross-sectionally, it is yet to be examined or established over time. The current pilot study examined the effects of subjective sleep quality on objective cognition in pwMS across a 5‚ÄövÑv¨6-year period. Baseline differences between pwMS and healthy individuals without MS, and differences between baseline and follow-up in pwMS, were also examined. Perceived sleep quality was assessed using the Pittsburgh Sleep Quality Index and cognitive function was measured using Rao‚ÄövÑv¥s Brief Repeatable Neuropsychological Battery. Results indicated that perceived sleep quality is not meaningfully related to objective cognition over time. PwMS displayed poorer cognition compared to individuals without MS at baseline. Neither sleep quality nor cognition declined in pwMS over 5-6 years. Future research should examine alternative sleep constructs such as objective sleep.

description: We report the realization of a Bose-Einstein condensate (BEC) in the hydrodynamic regime. The hydrodynamic regime is reached by evaporative cooling at a relative low density suppressing the effect of avalanches. With the suppression of avalanches a BEC containing 120.10^6 atoms is produced. The collisional opacity can be tuned from the collisionless regime to a collisional opacity of more than 3 by compressing the trap after condensation. In the collisional opaque regime a significant heating of the cloud at time scales shorter than half of the radial trap period is measured. This is direct proof that the BEC is hydrodynamic.

description: Κατά τη διδασκαλία του μαθήματοςτης φυσικής αγωγής στο σχολείο εμπλέκονται τόσο ψυχικοί όσο και κοινωνικοί παράγοντες. Μία από τις παραμέτρους που σχετίζεται με την ψυχοκοινωνική και γνωστική ανάπτυξη και κατέχει κεντρική θέση στην όλη διαδικασία της κοινωνικοποίησης του παιδιού είναι η ηθικότητα. Σκοπός της μελέτης που έγινε στα πλαίσια του μαθήματος της φυσικής αγωγής ήταν να διερευνηθεί η αποτελεσματικότητα ενός προγράμματος παρέμβασης στην ανάπτυξη του ηθικού διαλογισμού και κατά συνέπεια της ηθικότητας μαθητών και μαθητριών του Γυμνασίου. Το δείγμα αποτέλεσαν συνολικά 310 μαθητές και μαθήτριες. Αξιολογήθηκαν στην τελική φάση συνολικά 246 μαθητές/τριες εξισωμένοι μεταξύ τους ως προς το φύλο (Ομάδα παρέμβασης=152 και Ομάδα Ελέγχου=94). Για τη συλλογή των δεδομένων χρησιμοποιήθηκαν: 1) τα ερωτηματολόγια: α) BVCI, β) DIT, γ) HPPBI, και 2) η Συμμετοχική παρατήρηση (μη-δομημένη παρατήρηση) του καθηγητή φυσικής αγωγής, βάσει οδηγού, σχεδίου, παρατήρησης. Διαπιστώθηκε ότι οι μαθητές και οι μαθήτριες, μετά την εφαρμογή του προγράμματος παρέμβασης βελτίωσαν τον ηθικό τους διαλογισμό ως προς τα αθλητικά και τα κοινωνικά ζητήματα και παρουσίασαν θετικότερη κοινωνικοηθική συμπεριφορά τόσο στο καθημερινό μάθημα της φυσικής αγωγής όσο και κατά τη διάρκεια του εσωτερικού πρωταθλήματος αθλοπαιδιών.
description: During the teaching of physical education in school, both physical and social parameters are involved. One of the parameters relating to the psychosocial and cognitive development owing main position to the whole procedure of a youth's socializing, is morality. The purpose of the study, carried out within the bounds of physical education classes, was to be researched the effectiveness of an intervention program in the development of the moral reasoning and consequently of the morality of junior high school male and female students. The sample was consisted of 310 both boys and girls school students in all. Finally 246 school boys and girls were evaluated, equally numbered boys and girls (intervention group=152 and control group=94). For the data collection were used: 1) Inventories: a) The HBVI, b) DIT and c) The HPPBI and 2) The participating observation (non-structural observation) from the physical education's teacher based on a guidance, plan of observation. It was confirmed that school boys and girls improved their moral reasoning, relating to the athletic and social affairs, after applying the intervention program and they presented more positive socialmoral behavior, both in every day's class of physical education and during the internal sport championship.

Η συλλογή των δεδομένων έγινε με την τεχνική της συνέντευξης αναγνώρισης παραδειγμάτων, προφορικά έργα τριάδων και γραπτά έργα δόμησης προσωπικών ταξινομήσεων και ημιδομημένες συνεντεύξεις αντίστοιχα. Η ανάλυση των δεδομένων έγινε με τη μέθοδο της διαρκούς σύγκρισης και με ποσοτικά περιγραφικά στατιστικά στοιχεία. Τα ευρήματα της μελέτης δείχνουν ότι: α) η σημασία που προσδίδουν παιδιά και εκπαιδευτικοί στην έννοια "ζώο" είναι περιορισμένη και ανθρωποκεντρική, β) οι βιολογικές ταξινομήσεις στα μεν παιδιά έχουν περιορισμένη καταγραφή στους δε εκπαιδευτικούς προσεγγίζουν περισσότερο τις λαϊκές βιολογικές κατηγορίες παρά τις επιστημονικές και γ) οι αντιλήψεις και οι αξίες που αφορούν τη χρήση των ζώων είναι κατά κύριο λόγο ανθρωποκεντρικές, ενώ στις αντιλήψεις που σχετίζονται με τα άγρια είδη εμφανίζονται και ισχυρά ηθικά και οικολογικά επιχειρήματα. Οι σημασιοδοτήσεις και οι αντιλήψεις παιδιών και εκπαιδευτικών παραπέμπουν σε ιστορικές ιδέες ο αριστοτελικής προέλευσης "άνθρωπος ως γνωμικός τύπος" και η "Μεγάλη Αλυσίδα των Οντων" και αντιστοιχούν στο περιεχόμενο των λαϊκών βιολογικών εννοιών και κατηγοριοποιήσεων.
description: The study focuses on Primary School pupils' and teachers' concepts, classifications, values and views about animals. The research was conducted by means of interview about instances technique, oral oddity tasks, paper and pencil tasks about personaltaxonomies and semi-structured interviews. Data were analysed with constant comparative method. Results showed that the meaning of pupils' and teachers' concept "animal" is restricted and anthropocentric. In pupils' classifications non-biological taxonomic categories are predominant. Teachers biological classifications are more similar to folkbiological categories than to scientific taxonomic concepts. Anthropocentric values but also moralistic and ecological values are easily detected in pupils' and teachers notions about animals. Pupils' and teachers' meaning about "animal" and the related notions are similar with historic ideas like Aristoteles' "human as the rule" and the "Great chain of Being". Additionaly meanings and classifications are similar to folkbiological meanings and classifications.
Natural, forced and mixed convection in a vertical cross-corrugated channel

Publisher: name: University of British Columbia

description: Natural, forced and mixed convection heat transfer in a vertical cross-corrugated channel have been experimentally studied, using air as a working fluid. The channel is formed by two transversely positioned corrugated sheets and two flat side-walls which are thermally insulated. The thermal boundary condition is asymmetric and is such that one sheet is radiant-heated and the other is thermally insulated. A hot-wire anemometer and thermocouples were used to measure the fluid velocity and temperature, as well as the wall temperature. The local heat flux across the heated corrugated sheet was also measured with heat flow sensors. In the natural convection experiments, the effect of channel gap on heat transfer was studied. The results show that the Nusselt number NuL based on channel length was larger at the smaller gap than at the larger gap under natural convective flow. This may be due to the specific geometry of the cross-corrugated channel; the boundary layer of the fluid develops from the heated sheet and interacts with the other insulated sheet. For the smaller gap, the interaction of the boundary layer is probably more vigorous compared to the case of the larger gap, which eventually changes the flow pattern and increases the heat transfer. Under forced convection, a heat transfer correlation has been developed and a comparison was made with other similar work. A high heat transfer coefficient in this crosscorrugated channel was achieved with a reasonable value of the friction factor. Local heat transfer rate on the heated corrugated sheet was measured at several different locations with heat flow sensors. The result showed that local heat flux at the valley of the corrugation was less than that at the peak. The ratio of these two heat fluxes was correlated with Reynolds number, and the difference of these two heat fluxes became small as Reynolds number increases in the present experimental range. Mixed convection has been presented in a way which allows comparison to the 'pure' forced convection. Mixed convection in the cross-corrugated channel has shown similar phenomena as buoyancy-aided pipe flow. Natural convection effect on mixed convection was very small in this experimental range.

description: The aim of the present work is to provide necessary information for the estimation and evaluation of the daylight levels in the ambient environment, as well as in interior spaces. The thesis focuses on the development of new mathematical models and computational tools adequate for the Greek region which enable the maximum utilization of daylight in the building sector and thus contribute to the improvement of the energy behavior and the formation of visual conditions indoors. More specifically, after a short description of the perpetual relationship between daylighting and architecture the effect of daylight in various aspects of human life and the presentation of the theoretical background of the topic the following subjects are thoroughly examined 1)The development of new mathematical models for the estimation of daylight levels in the ambient environment applied for the Greek region 2) the development of a new computational tool for the simulation of the indoor daylight conditions. The performance of the proposed tool was tested with existing simulating software and theoretical tools, as well with real measurements 3)the analysis of the main parameters, which contribute to the formation of daylight levels of an interior space

description: We surveyed thirteen very low mass (VLM; M < 0.2 M_sun) objects in the Taurus star-forming region using near-infrared diffraction-limited imaging techniques on the W.M. Keck I 10 m telescope. Of these thirteen, five were found to be binary, with separations ranging from 0.04" to 0.6" and flux ratios from 1.4 to 3.7. In all cases, the companions are likely to be physically associated with the primaries (probability > 4-sigma). Using the theoretical models of Baraffe et al. (1998), we find that all five new companions, as well as one of the primaries, are likely brown dwarfs. The discovery of these systems therefore increases the total number of known, young VLM binaries by ~50%. These new systems, along with other young VLM binaries from the literature, have properties that differ significantly from older field VLM binaries in that the young systems have wider separations and lower mass ratios, supporting the idea that VLM binaries undergo significant dynamical evolution ~5 - 10 Myr after their formation. The range of separations of these binaries, four of which are over 30 AU, argues against the ejection scenario of brown dwarf formation. While several of the young, VLM binaries discovered in this study have lower binding energies than the previously suggested minimum for VLM binaries, the apparent minimum is still significantly higher than that found among higher mass binaries. We suggest that this discrepancy may be due to the small mass of a VLM binary relative to the average perturbing star, leading to more substantial changes in their binding energy over time.

description: High resolution precision spectroscopy provides a multitude of robust techniques for probing exoplanetary atmospheres. We present multiple VLT/ESPRESSO transit observations of the hot-Jupiter exoplanet WASP-19b with previously published but disputed atmospheric features from low resolution studies. Through spectral synthesis and modeling of the Rossiter-McLaughlin (RM) effect we calculate stellar, orbital and physical parameters for the system. From narrow-band spectroscopy we do not detect any of H\,I, Fe\,I, Mg\,I, Ca\,I, Na\,I and K\,I neutral species, placing upper limits on their line contrasts. Through cross correlation analyses with atmospheric models, we do not detect Fe\,I and place a 3$σ$ upper limit of $\log\,(X_{\textrm{Fe}}/X_\odot) \approx -1.83\,\pm\,0.11$ on its mass fraction, from injection and retrieval. We show the inability to detect the presence of H$_2$O for known abundances, owing to lack of strong absorption bands, as well as relatively low S/N ratio. We detect a barely significant peak (3.02\,$\pm$\,0.15\,$σ$) in the cross correlation map for TiO, consistent with the sub-solar abundance previously reported. This is merely a hint for the presence of TiO and does \textit{not} constitute a confirmation. However, we do confirm the presence of previously observed enhanced scattering towards blue wavelengths, through chromatic RM measurements, pointing to a hazy atmosphere. We finally present a reanalysis of low resolution transmission spectra of this exoplanet, concluding that unocculted starspots alone cannot explain previously detected features. Our reanalysis of the FORS2 spectra of WASP-19b finds a $\sim$\,100$\times$ sub-solar TiO abundance, precisely constrained to $\log\,X_{\textrm{TiO}} \approx -7.52 \pm 0.38$, consistent with the TiO hint from ESPRESSO. We present plausible paths to reconciliation with other seemingly contradicting results.

description: The recent theoretical discovery of families of travelling wave solutions in pipe flow at Reynolds numbers lower than the transitional range naturally raises the question of their relevance to the turbulent transition process. Here a series of numerical experiments are conducted in which we look for the spatial signature of these travelling waves in transitionary flows. Working within a periodic pipe of 5D (diameters) length, we find that travelling waves with low wall shear stresses (lower branch solutions) are on a surface which separates initial conditions which uneventfully relaminarise and those which lead to a turbulent evolution. Evidence for recurrent travelling wave visits is found in both 5D and 10D long periodic pipes but only for those travelling waves with low-to-intermediate wall shear stress and for less than about 10% of the time in turbulent flow. Given this, it seems unlikely that the mean turbulent properties such as wall shear stress can be predicted as an expansion over the travelling waves in which their individual properties are appropriately weighted. Rather, further dynamical structures such as periodic orbits need to be isolated and included in any such expansion.

description: Διαπιστώνεται ότι παρότι η διαιτησία είναι ένας θεσμός που διαπλάστηκε αρχικά στην περιοχή του ιδιωτικού δικαίου, διεθνώς και ιδίως σε χώρες που έχουν νομικά συστήματα αντίστοιχα με το δικό μας, γίνεται δεκτό, τόσο στο επίπεδο της θεωρίας όσο και στο επίπεδο της νομολογίας, ότι και διαφορές στις οποίες το ένα από τα συνερχόμενα μέρη είναι το κράτος και ειδικώς δημοσίου δικαίου διαφορές, είναι δυνατό να υπαχθούν σε διαιτητική επίλυση. Θεμελιώνεται το γιατί στη χώρα μας πρέπει να θεωρηθεί ότι παρόλες τις αμφισβητήσεις που κατά καιρούς διατυπώθηκαν, είναι θεμιτή η παραπομπή δημοσίου δικαίου διαφορών σε διαιτησία. Η μελέτη πάντως βασίζεται όχι μόνο στα δεδομένα της εγχώριας θεωρίας και νομολογίας αλλά και στα δεδομένα άλλων χωρών και νομικών συστημάτων και με την έννοια αυτή προσλαμβάνει και διάσταση μιας συγκριτικού δικαίου θεώρησης. Η μεταφορά της διαιτησίας στο πεδίο του δημοσίου δικαίου και ενγένει των δημοσίου δικαίου σχέσεων, παρουσιάζει σημαντικές διαφοροποιήσεις, ιδιοτυπίες και προβλήματα τόσο ουσιαστικού όσο και δικονομικού δικαίου. Ολες αυτές οι ιδιαιτερότητες του θεσμού της διαιτησίας, κατά την στο πεδίο του δημοσίου δικαίου και των δημοσίου δικαίου σχέσεων μεταφορά του, σκοπεύει να αντιμετωπίσει η παρούσα διατριβή. Επιδιώκεται να δειχθεί ότι η δημοσίου δικαίου διαιτησία έχει μιαν αυτοτέλεια, παρόλον ότι η αυτοτέλεια αυτή νοείται μόνον ως σχετική αυτοτέλεια έναντι της διατησίας στο πεδίο των ιδιωτικού δικαίου σχέσεων
description: It's founded that although arbitration is a statute which was formed firstly in the field of private law, internationally and especially to countries that have legal systems similar to our, it is accepted that both at theoritical level and at practical(precedents)level, disputes in which one of the parties is the state, even more specifically public law disputes, can be solved by arbitration. It's established why arbitration in our country must be acceptable, although disputed reference to arbitration is legitimate for matters which concern public law differences. The study is based on both local theory and precedents, as well as other country and their legal systems data. Under this view it takes up a dimension of comparative law. The transfer of the statute of arbitration at the public law field and more generally public relations, presents essential differences, particularities and problems both real right or procedural law. The present doctorate thesis indents to confront the transfer of the particuliarities of arbitration statute in the field of public law. It is indended to show the public law arbitration selfsufficiency, although that this shelf sufficiency is only relative to arbitration in the field of private law relations

description: The main issues studied in this doctoral dissertation are fitting a smooth Reciever Operating Characteristic(ROC) curve, statistical inference in the analysis of ROC curves and the use of ROC curves in multivariate statistical methods. The first chapter is introductory. The methods of smooth ROC curve fitting are reviewed in chapter two and local smoothing estimators are proposed. The use of goodness-of-fit methodology is proposed for statistical inference based on ROC curves instead of the classical methods. In the last chapter the use of ROC curves in multivariate statistical analysis is studied. S-plus and Matlab code is given in the appendix

description: In several previous studies, quasars exhibiting broad emission lines with >1000 km/s velocity offsets with respect to the host galaxy rest frame have been discovered. One leading hypothesis for the origin of these velocity-offset broad lines is the dynamics of a binary supermassive black hole (SMBH). We present high-resolution radio imaging of 34 quasars showing these velocity-offset broad lines with the Very Long Baseline Array (VLBA), aimed at finding evidence for the putative binary SMBHs (such as dual radio cores), and testing the competing physical models. We detect exactly half of the target sample from our VLBA imaging, after implementing a 5 detection limit. While we do not resolve double radio sources in any of the targets, we obtain limits on the instantaneous projected separations of a radio-emitting binary for all of the detected sources under the assumption that a binary still exists within our VLBA angular resolution limits. We also assess the likelihood that a radio-emitting companion SMBH exists outside of our angular resolution limits, but its radio luminosity is too weak to produce a detectable signal in the VLBA data. Additionally, we compare the precise sky positions afforded by these data to optical positions from both the SDSS and Gaia DR2 source catalogs. We find projected radio/optical separations on the order of 10 pc for three quasars. Finally, we explore how future multi-wavelength campaigns with optical, radio, and X-ray observatories can help discriminate further between the competing physical models.

description: The main aim of the dissertation is to define the legal nature and function of decision regarding all unions and legal entities of private law. The method that it is applied is abstractive and composive. The common characteristics of decision are gathered from all particular unions and legal entities of private law and continuesly are reduced to general principles able to be applied to the legal phenomenon "decision". Certain conclusions are made concerning the legal nature, the function, the validity and invalidity of decision. The two last subjects have a particular importance for the daily praxis of all legal entities(associations, cooperations, companies, etc.)

description: The goal of this research is to study the illegal or unauthorized building in forest lands of Greece as a result of the absense of forest cadastre. As application area the housisng estate of "Kissos" of mountain Hortiatis in Thessaloniki was selected. A methodology based on digital photogrammetry and G.I.S. has been developed, in order to determine the environmental and zoning impacts of forest ecosystems. As a result of this research it emerged that illegal building is one of the most important causes of forest land use changes in Greece, as well as the environmental impacts of this phenomenon are very destructive for forest ecosystems and natural environment.

description: The electron-phonon interaction in thin Ag-nanofilms epitaxially grown on Cu(111) is investigated by temperature-dependent and angle-resolved photoemission from silver quantum-well states. Clear oscillations in the electron-phonon coupling parameter as a function of the silver film thickness are observed. Different from other thin film systems where quantum oscillations are related to the Fermi-level crossing of quantum-well states, we can identify a new mechanism behind these oscillations, based on the wavefunction localization of the quantum-well states in the film.

description: We report the successful buffer-gas cooling and magnetic trapping of chromium atoms with densities exceeding $10^{12}$ atoms per cm$^{3}$ at a temperature of 350 mK for the trapped sample. The possibilities to extend the method to buffer-gas cool and magnetically trap molecules are discussed. To minimize the most important loss mechanism in magnetic trapping, molecules with a small spin-spin interaction and a large rotational constant are preferred. Both the CrH ($^6Σ^+$ ground state) and MnH ($^7Σ^+$) radicals appear to be suitable systems for future experiments.
