Fading Gravity and Self-Inflation

description: We study the cosmology of a toy modified theory of gravity in which gravity shuts off at short distances, as in the fat graviton scenario of Sundrum. In the weak-field limit, the theory is perturbatively local, ghost-free and unitary, although likely suffers from non-perturbative instabilities. We derive novel self-inflationary solutions from the vacuum equations of the theory, without invoking scalar fields or other forms of stress energy. The modified perturbation equation expressed in terms of the Newtonian potential closely resembles its counterpart for inflaton fluctuations. The resulting scalar spectrum is therefore slightly red, akin to the simplest scalar-driven inflationary models. A key difference, however, is that the gravitational wave spectrum is generically not scale invariant. In particular the tensor spectrum can have a blue tilt, a distinguishing feature from standard inflation.

description: Abstract The microquasar SS 433 exhibits in H alpha intermittent flares, Doppler shifted to both the red and the blue. The mean remembers the orbital phase of the compact object. I show that the flares are not intermittent sightings of an accretion disk; rather, plasma must be expelled through the L2 point, thus remembering the phase of the orbit as it invades the space beyond the system. That space has been mapped with GRAVITY observations of a similar flare, revealing a strong rotation component.

description: The Gaia optical reference frame is intrinsically undefined with respect to global orientation and spin, so it needs to be anchored in the radio-based International Celestial Reference Frame (ICRF) to provide a referenced and quasi-inertial celestial coordinate system. The link between the two fundamental frames is realized through two samples of distant extragalactic sources, mostly AGNs and quasars, but only the smaller sample of radio-loud ICRF sources with optical counterparts is available to determine the mutual orientation. The robustness of this link can be mathematically formulated in the framework of functional principal component analysis using a set of vector spherical harmonics to represent the differences in celestial positions of the common objects. The weakest eigenvectors are computed, which describe the greatest deficiency of the link. The deficient or poorly determined terms are specific vector fields on the sphere which carry the largest errors of absolute astrometry using Gaia in reference to the ICRF. This analysis provides guidelines to the future development of the ICRF maximizing the accuracy of the link over the entire celestial sphere. A measure of robustness of a least-squares solution, which can be applied to any linear model fitting problem, is introduced to help discriminate between reference frame tie models of different degrees.

description: The G$^0$ parity-violation experiment at Jefferson Lab (Newport News, VA) is designed to determine the contribution of strange/anti-strange quark pairs to the intrinsic properties of the proton. In the forward-angle part of the experiment, the asymmetry in the cross section was measured for $\vec{e}p$ elastic scattering by counting the recoil protons corresponding to the two beam-helicity states. Due to the high accuracy required on the asymmetry, the G$^0$ experiment was based on a custom experimental setup with its own associated electronics and data acquisition (DAQ) system. Highly specialized time-encoding electronics provided time-of-flight spectra for each detector for each helicity state. More conventional electronics was used for monitoring (mainly FastBus). The time-encoding electronics and the DAQ system have been designed to handle events at a mean rate of 2 MHz per detector with low deadtime and to minimize helicity-correlated systematic errors. In this paper, we outline the general architecture and the main features of the electronics and the DAQ system dedicated to G$^0$ forward-angle measurements.

From saviour to witness : the transformation of the ethos of Roman Catholic missionaries, 1890-1990, with particular reference to Latin America
Creators: name: Weeren, John S.
Publisher: name: University of British Columbia
Year: 2011

description: This thesis explores the transformation which has occurred in Roman Catholic missionaries' conceptions of their hosts and themselves between 1890 and 1990. Through the delineation and contextualization of the ethos which prevailed in missionary circles at the beginning and at the end of this period — the one definitively losing its ascendancy to the other in the 1960s — this thesis demonstrates that the distance separating missionaries and their hosts has narrowed dramatically. In 1890 most missionaries believed that the religiocultural systems in which they worked were wastelands in comparison with their own and that the sooner they could be harmonized with western norms the better it would be. In 1990 most missionaries believed that the religiocultural systems in which they worked contained great riches and that as much could be learned from their hosts as could be imparted to them, if not more. Equality, once based on uniformity, is now acknowledged in diversity. Underlying these changes has been the evolving character of the religious and secular worlds in which missionaries have lived, the cardinal feature of which has been the erosion of a Eurocentric model of human existence. In sum, this thesis, which integrates Latin America into a global pattern of missionary thought and action, illuminates the ethos of missionaries past and present and the foundation on which each has rested.

description: We have considered a system where the interaction, v(r) = v_IS(r) + xi^2 v_MF(r), is given as a linear combination of two potentials, each of which being characterized with a well-defined critical behavior: for v_IS(r) we have chosen the potential of the restricted primitive model which is known to belong to the Ising 3D (IS) universality class, while for v_MF(r) we have considered a long-range interaction in the Kac-limit, displaying mean field (MF) behavior. We study the performance of two theoretical approaches and of computer simulations in the critical region for this particular system and give a detailed comparison between theories and simulation of the critical region and the location of the critical point. Both, theory and simulation give evidence that the system belongs to the MF universality class for any positive value of xi and that it shows only non-classical behavior for xi=0. While in this limiting case theoretical approaches are known to fail, we find good agreement for the critical properties between the theoretical approaches and the simulations for xi^2 larger than 0.05.

UML Modeling to TM Modeling and Back

description: Certainly, the success of the Unified Modeling Language (UML) as the de facto standard for modeling software systems does not imply closing the door on scientific exploration or experimentation with modeling in the field. Continuing studies in this area can produce theoretical results that strengthen UML as the leading modeling language. Recently, a new modeling technique has been proposed called thinging machine (TM) modeling. This paper utilizes TM to further understand UML, with two objectives: (a) Fine issues in UML are studied, including theoretical notions such as events, objects, actions, activities, etc. Specifically, TM can be used to solve problems related to internal cross-diagram integration. (b) TM applies a different method of conceptualization, including building a model on one-category ontology in contrast to the object-oriented paradigm. The long-term objective of this study is to explore the possibility of TM complementing certain aspects in the UML methodology to develop and design software systems. Accordingly, we alternate between UML and TM modeling. A sample UML model is redesigned in TM, and then UML diagrams are extracted from TM. The results clarify many notions in both models. Particularly, the TM behavioral specification seems to be applicable in UML.

Η ανάλυση του χώρου πραγματοποιείται σε χωροταξική, πολεοδομική και αρχιτεκτονική κλίμακα, στο συγχρονικό και διαχρονικό πεδίο, με την υιοθέτηση δύο βασικών μεθοδολογικών εργαλείων της ιστορικής γεωγραφίας και της αρχαιολογίας του χώρου : το χάρτη κατανομής των θέσεων και τις κατόψεις των οικισμών. Η διαχρονική εξέλιξη της χωροταξίας των προϊστορικών οικισμών στον ελλαδικό χώρο καταδεικνύει την αρχική συγκέντρωση των οικισμών στο βορρά, τη σταδιακή εξάπλωση προς το νότο και την τελική μετατόπιση του κέντρου βάρους της ανθρώπινης παρουσίας στο νότο. Διαπιστώνεται ότι η εξέλιξη αυτή συνοδεύτηκε από αλλαγές στην οικονομία, τις κοινωνικές σχέσεις που στήριζαν και σε ορισμένα πολιτισμικά χαρακτηριστικά. Οι αλλαγές στο σύνολο των παραμέτρων αποτυπώνονται στην εξέλιξη της πολεοδομικής μορφής των οικισμών και της αρχιτεκτονικής των κατασκευών από απλές και ρευστές σε πιο σύνθετες και συμπαγείς μορφές. Οι αλλαγές στην οργάνωση και χρήση του χώρου συνοδεύτηκαν, επίσης, από αλλαγές στο περιβαλλοντικό πλαίσιο, είτε με την αλλαγή του ίδιου του περιβάλλοντος, λόγω ανθρωπογενών ή φυσικών διαδικασιών, είτε με τη μετατόπιση των οικισμών σε περιοχές με διαφορετικά περιβαλλοντικά χαρακτηριστικά
description: This thesis constitutes an integrated study based on the latest archaelogical data and aims at filling in the gaps in our knowledge of the form of prehistoric settlements in Greece. Spatial analysis is conducted on a spatial planning, settlement patterning and architectural level, both synchronically and diachronically, by adopting two basic methodological tools used in historical geography and spatial archaelogy : a settlement distribution map and plans of the settlements under study. The examination of prehistoric settlement in Greece on a diachronical level clearly shows their initial concentration in the north, their gradual spreading southwards and finally, their prevailine presence mainly in the south. This work also concludes that this development goes hand-in-hand with changes in economy, the social relationship supporting it and in certain cultural features. Such changes are reflected in the development of the settlement pattern and the architecture of structures, i.e. the transition from simpleand flexible to more complex and compact forms. Changes in the organization and use of space are also interwoven with changes in the environment, either in the natural surroundings themselves, caused by human or natural interventions, or due to the movement of settlers to region of different environmental characteristics
Fringe festivals, cultural politics, and the negotiation of subjectivity
Creators: name: Willems-Braun, Bruce
Publisher: name: University of British Columbia
Year: 2011

description: Social theory, influenced most recently by poststructuralism, has found renewed interest in questions concerning the subject, representation, ideology, and social formations. Rejecting earlier structuralist attempts to theorize the subject as ultimately tied to essentialist conceptualizations of society, it is suggested, rather, that individual subjects and social formations are constituted within a plurality of contesting discourses which form no totalizing logic, and in which no necessary relations can be defined. Attention has thus shifted to culture - its products, practices and representations - as sites where subjectivity (including gender, race, and class identities) and social formations are constructed, challenged and transformed. Social formations are viewed as mutable, their elements always able to be articulated within alternate formations. It is at the level of representation and dissemination, then, that a "politics of culture" emerges. This thesis examines Canada's Fringe Festivals as sites where subjectivity is negotiated and social formations constituted and transformed. These festivals are shown to provide possibilities for diversity and plurality - providing room for the production and consumption of cultural products which would otherwise remain invisible within the rationalized structures of Canadian society. This occurs through their accessibility (both to artists and patrons), their inversion of the wage relations of traditional theatre, their subversion of criticism (excellence and universality) and their transformation of rationalized urban spaces into spaces of "festivity." The festivals encourage interaction between patrons, artists and "representations" thereby moderating the influence of traditional evaluative media and positioning the negotiation of "meaning" in an intersubjective, "public" context. While an emerging literature on festivals has emphasized their "liminality" - considering them spaces of pure possibility where the structures of everyday life are suspended and transformed - the present work argues that such events should be understood as "situated" - inseparable from the social relations of the city. Whether examining characteristics of the Fringe "public," the selective images used in promotional literature, the production of "taste" across social groups, or the instrumental rationality behind state support of the festivals, the Fringe Festivals, their products and participants, are found to be constituted within multiple (often contradictory) discourses which simultaneously subvert and reproduce existing social formations.

Here, we report the fabrication on-chip erbium-doped LNOI waveguide amplifiers based on electron beam lithography and inductively coupled plasma reactive ion etching. A net internal gain of ~30 dB/cm in communication band was achieved in the fabricated waveguide amplifiers under the pump of a 974-nm continuous laser. This work develops new active devices on LNOI and will promote the development of LNOI integrated photonics.

Phase transitions and configuration space topology

Publisher: name: arXiv
Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Equilibrium phase transitions may be defined as nonanalytic points of thermodynamic functions, e.g., of the canonical free energy. Given a certain physical system, it is of interest to understand which properties of the system account for the presence of a phase transition, and an understanding of these properties may lead to a deeper understanding of the physical phenomenon. One possible approach of this issue, reviewed and discussed in the present paper, is the study of topology changes in configuration space which, remarkably, are found to be related to equilibrium phase transitions in classical statistical mechanical systems. For the study of configuration space topology, one considers the subsets M_v, consisting of all points from configuration space with a potential energy per particle equal to or less than a given v. For finite systems, topology changes of M_v are intimately related to nonanalytic points of the microcanonical entropy (which, as a surprise to many, do exist). In the thermodynamic limit, a more complex relation between nonanalytic points of thermodynamic functions (i.e., phase transitions) and topology changes is observed. For some class of short-range systems, a topology change of the M_v at v=v_t was proved to be necessary for a phase transition to take place at a potential energy v_t. In contrast, phase transitions in systems with long-range interactions or in systems with non-confining potentials need not be accompanied by such a topology change. Instead, for such systems the nonanalytic point in a thermodynamic function is found to have some maximization procedure at its origin. These results may foster insight into the mechanisms which lead to the occurrence of a phase transition, and thus may help to explore the origin of this physical phenomenon.

description: We aimed to determine the epidemiology and clinical management of patients presenting to an Australian tertiary emergency department (ED) with a suspected snake bite. Nepean Hospital covers a geographical area known to harbour venomous elapid snake species. A Retrospective chart review of all patients presenting to Nepean ED from 2011 to 2020 was performed. We searched the electronic medical records (eMR) for triage presentations including search terms of “snakebite”, “bite” “envenomation”, or “bite-snake” and a discharge or independent diagnosis of “snakebite” or “envenomation”. Our review identified 110 patients presenting with snakebite, of whom nine had signs or symptoms indicating envenomation. The most common envenomation syndrome was venom-induced consumption coagulopathy (VICC) and the most commonly suspected culprit snake was the Eastern Brown Snake. Our data broadly agreed with national data on epidemiology and demographics. We noted a satisfactory rate of compliance with local snake bite protocols with evidence of early diagnosis and antivenom administration. We had no cases of anaphylaxis and one case of serum sickness. Our study of a tertiary hospital experience in the management of snake bite demonstrated an appropriate adherence to national guidelines and early clinician recognition of envenomation syndromes. It also demonstrated appropriate antivenom use without obvious time delay.

description: Uniform asymptotic formulae for arrays of complex numbers of the form $(f_{r,s})$, with $r$ and $s$ nonnegative integers, are provided as $r$ and $s$ converge to infinity at a comparable rate. Our analysis is restricted to the case in which the generating function $F(z,w):=\sum f_{r,s} z^r w^s$ is meromorphic in a neighborhood of the origin. We provide uniform asymptotic formulae for the coefficients $f_{r,s}$ along directions in the $(r,s)$-lattice determined by regular points of the singular variety of $F$. Our main result derives from the analysis of a one dimensional parameter-varying integral describing the asymptotic behavior of $f_{r,s}$. We specifically consider the case in which the phase term of this integral has a unique stationary point, however, allowing the possibility that one or more stationary points of the amplitude term coalesce with this. Our results find direct application in certain problems associated to the Lagrange inversion formula as well as bivariate generating functions of the form $v(z)/(1-w\cdot u(z))$.

description: Cold atoms in optical lattices are described in {\it real space} by multi-orbital mean-field Ansätze. In this work we consider four typical systems: (i) spinless identical bosons, (ii) spinor identical bosons (iii), Bose-Bose mixtures, and (iv) Bose-Fermi mixtures and derive in each case the corresponding multi-orbital mean-field energy-functional and working equations. The notions of {\it dressed} Wannier functions and Wannier spinors are introduced and the equations defining them are presented and discussed. The dressed Wannier functions are the set of orthogonal, translationally-equivalent orbitals which minimizes the energy of the Hamiltonian including boson-boson (particle-particle) interactions. Illustrative examples of dressed Wannier functions are provided for spinless bosonic atoms and mixtures in one-dimensional optical lattices.

description: Sparse array (SA) geometries, such as coprime and nested arrays, can be regarded as a concatenation of two uniform linear arrays (ULAs). Such arrays lead to a significant increase of the number of degrees of freedom (DOF) when the second-order information is utilized, i.e., they provide long virtual difference coarray (DCA). Thus, the idea of this paper is based on the observation that SAs can be fitted through concatenation of sub-ULAs. A corresponding SA design principle, called ULA fitting, is then proposed. It aims to design SAs from sub-ULAs. Towards this goal, a polynomial model for arrays is used, and based on it, a DCA structure is analyzed if SA is composed of multiple sub-ULAs. SA design with low mutual coupling is considered. ULA fitting enables to transfer the SA design requirements, such as hole free, low mutual coupling and other requirements, into pseudo polynomial equation, and hence, find particular solutions. We mainly focus on designing SAs with low mutual coupling and large uniform DOF. Two examples of SAs with closed-form expressions are then developed based on ULA fitting. Numerical experiments verify the superiority of the proposed SAs in the presence of heavy mutual coupling.

Μέσα από τη διερεύνηση των τριών ορισμών της γνώσης (Α'γνώση είναι αίσθηση, Β' γνώση είναι αληθής δόξα, Γ' γνώση είναι η μετά λόγου αληθής δόξα), της θεωρίας των αισθητηριακών δεδομένων και της υπεράσπισης του Πρωταγόρα θα αναδειχθεί ο τρόπος προσέγγισης της ουσίας της πλατωνικής γνώσης. Η προσέγγιση θα γίνει μέσω του λογιστικού της ψυχής που πρωτοστατεί στη διαλεκτική του Πλάτωνα. Αν και η πλατωνική θέση για το ζήτημα της γνώσης δεν αναφέρεται άμεσα, η μέθοδος που προτείνεται είναι η αναλυτικότερη και πειστικότερη στο πλατωνικό έργο. Εξετάστηκε επίσης η σχέση της γνώσης με την πολιτική και ο καθοριστικός ρόλος του φιλοσόφου στην κατάληψη της γνώσης και της ουσίας(πάρεργο)
description: In Plato's "Theaetetos" we find the important value of Plato's theory of knowledge through the three definitions(A' knowledge is perception, B' knowledge is true opinion, C' knowledge is true opinion with 'logos'), the sense data theory and the defense of protagoras we notice the method of Plato's epistemology. The most important part in this method has the logic substance of soul. This part is also important for Platos's dialectic. Plato didn't say obviously his 'thesis'. But the method is able to persuade anyone. The relation of knowledge and politic and the philosopher significant role in order to percieve the knowledge and the essence are two important issues of this dissertation

description: The evolution of porous structure, potential energy and local density in binary glasses under oscillatory shear deformation is investigated using molecular dynamics simulations. The porous glasses were initially prepared via a rapid thermal quench from the liquid state across the glass transition and allowed to phase separate and solidify at constant volume, thus producing an extended porous network in an amorphous solid. We find that under periodic shear, the potential energy decreases over consecutive cycles due to gradual rearrangement of the glassy material, and the minimum of the potential energy after thousands of shear cycles is lower at larger strain amplitudes. Moreover, with increasing cycle number, the pore size distributions become more skewed toward larger length scales where a distinct peak is developed and the peak intensity is enhanced at larger strain amplitudes. The numerical analysis of the local density distribution functions demonstrates that cyclic loading leads to formation of higher density solid domains and homogenization of the glass phase with reduced density.

description: Το ερευνητικό ενδιαφέρον μας ήταν διπλό : α)παρακολούθηση της ανάπτυξης της μη γλωσσικής γνώσης στο παιδί μέσα από το γλωσσικό 'παράθυρο' της μεταφοράς β)ανίχνευση των πρώϊμων σταδίων εξέλιξης της μεταφοράς μέσα από το μικρό παιδί. Βασικό ερώτημα : αν οι εκδηλώσεις της μη κυριολεξίας στη γλώσσα και τη σκέψη του παιδιού αποτελούν όψιμο στάδιο γνωστικής και γλωσσικής εξέλιξης, ή αποτελούν εμφανίσεις της δράσης ενός πρώϊμου μηχανισμού(πιθανόν έμφυτου) που κινητοποιεί την ανάπτυξη όσο της γλωσσικής, όσο και της μη γλωσσικής γνώσης. Ονομάσαμε αυτόν τον μηχανισμό 'συμπλεκτικό-μεταβιβαστικό' και θεωρήσαμε ότι εκδηλώσεις του αποτελούν τα φαινόμενα συναισθησίας, το παιχνίδι προσποίησης, οι υπερεπεκτάσεις, και η γλωσσική μη κυριολεξία(μεταφορά και παρομοίωση). Η διατριβή δομήθηκε ως εξής : κεφ Α'/Γλωσσική και Γνωστική ανάπτυξη του παιδιού. Γίνεται προσπάθεια συσχετισμού ορισμένων φαινομένων με συναφείς εκδηλώσεις στον γνωστικό και γλωσσικό τομέα. Β' κεφ/Μεταφορά. Βασικά σημεία : σχέση κυριολέξίας-μη κυριολεξίας, μεταφοράς-παρομοίωσης, θέματος-εστίας της μεταφορικής έκφρασης. κεφ. Γ'/Πειραματική προσέγγιση της σχέσης μεταφοράς-παιδιού : στόχος η απόδειξη ορισμένων υποθέσεων για την πρωϊμότητα της σχέσης παιδιού-μη κυριολεξίας και η ανάδειξη ιδιαίτερων πλευρών της παιδικής κατανόησης της μη κυριολεξίας
description: In this dissertation thw aim was two fold : a)we examine the development of non-linguiistic lnowledge in children with the help of linguistic data(metaphor) b)we investigate the process of metaphor development, especially at the early stages : children are a perfect source. The main question to answer was : if the expression of non literality in language and thought is a later developmental phase, or there is an early-operating system wich provoke the appearance of non-literal phenomena, perhaps it is one of the central motivators in the development of both, linguistic and non-linguistic knowledge. We call it 'the complexive-transmissive mechanism', which motivates the appearance of non literality. Some basic manifestations are synesthesia, pretend play, over extentions, metaphor, simile. We organize the dissertation in 3 sections : A/cognitive and linguistic development in children. We found significant parallels between linguistic(semantic/pragmatic) and cognitive development, a different classification. B/metaphor : the main points are literal-non literal relation, simile-metaphor, topic-vehicle relations and the comprehension of non literal expressions. c/metaphor and child : we expose our experimental data of little children's non literality comphrehension. We conclude that it is an early ability, metaphor gives better results than simile, and there are some interesting differences in child comprehension comparing to adult's
Structure-Constrained Process Graphs for the Process Semantics of Regular Expressions

description: Milner (1984) introduced a process semantics for regular expressions as process graphs. Unlike for the language semantics, where every regular (that is, DFA-accepted) language is the interpretation of some regular expression, there are finite process graphs that are not bisimilar to the process interpretation of any regular expression. For reasoning about graphs that are expressible by regular expressions modulo bisimilarity it is desirable to have structural representations of process graphs in the image of the interpretation. For '1-free' regular expressions, their process interpretations satisfy the structural property LEE (loop existence and elimination). But this is not in general the case for all regular expressions, as we show by examples. Yet as a remedy, we describe the possibility to recover the property LEE for a close variant of the process interpretation. For this purpose we refine the process semantics of regular expressions to yield process graphs with 1-transitions, similar to silent moves for finite-state automata.

description: We continue to investigate properties of the worldsheet conformal field theories (CFTs) which are conjectured to be dual to free large N gauge theories, using the mapping of Feynman diagrams to the worldsheet suggested in hep-th/0504229. The modular invariance of these CFTs is shown to be built into the formalism. We show that correlation functions in these CFTs which are localized on subspaces of the moduli space may be interpreted as delta-function distributions, and that this can be consistent with a local worldsheet description given some constraints on the operator product expansion coefficients. We illustrate these features by a detailed analysis of a specific four-point function diagram. To reliably compute this correlator we use a novel perturbation scheme which involves an expansion in the large dimension of some operators.

description: The thesis aims to systematize the theoretical issues concerning the assessment and planning of an archaeological exhibition. The museum phenomenon is treated as a communicational relationship among three major factors(the archaelogist-producer of the exhibit-, and the visitor-consumer of the exhibit-) which is effected in the normative frame of the museum. The first part briefly presents the discussion regarding Greek museums which was developed during the last two centuries and ends outlining the contemporary social and ideological conditions that determine the role of an archaelogical museum today, In this general theoretical frame the second part elaborates issues as the relation between the exhibition and the excavation and interpretation of the archaelogical data, the exhibition syntax, the exhibits' authenticity, the supporting texts, the interactivity etc.

Προτείνεται η αντιμετώπιση του μουσειακού φαινομένου ως μιας επικοινωνιακής σχέσης τριών παραγόντων : του αρχαιολόγου(παραγωγού του εκθέματος), του αρχαιολογικού αντικειμένου(εκθέματος) και του επισκέπτη(καταναλωτή του εκθέματος), η οποία αναπτύσσεται μέσα στο θεσμικό, ιδεολογικό και κατασκευαστικό πλαίσιο του μουσείου. Αρχικά γίνεται μια συνοπτική αναφορά στην συζήτηση σχετικά με την έκθεση των αρχαιοτήτων στην Ελλάδα από τον 18ο αι. μέχρι τις μέρες μας και στη συνέχεια δίνονται τα στοιχεία που συγκροτούν το ρόλο ενός αρχαιολογικού μουσείου σήμερα. Στο πλαίσιο των σύγχρονων κοινωνικών συνθηκών, επιχειρείται η ανάλυση επιμέρους θεμάτων, όπως η σχέση της έκθεσης με την ανασακαφή και τη μελέτη του αρχαιολογικού υλικού, η εκθεσιακή σύνταξη και τα εκθεσιακά μέσα, η αυθεντικότητα των εκθεμάτων, ο υπομνηματισμός, η διαδραστικότητα κτλ.

description: We report an extensive search for Lyman-alpha emitters (LAEs) at z=6.5 in the Subaru Deep Field. Subsequent spectroscopy with Subaru and Keck identified eight more LAEs, giving a total of 17 spectroscopically confirmed LAEs at z=6.5. Based on this spectroscopic sample of 17, complemented by a photometric sample of 58 LAEs, we have derived a more accurate Lyman-alpha luminosity function of LAEs at z=6.5, which reveals an apparent deficit at the bright end of ~0.75 mag fainter L*, compared with that observed at z=5.7. The difference in the LAE luminosity functions between z=5.7 and 6.5 is significant at the 3-sigma level, which is reduced to 2-sigma when cosmic variance is taken into account. This result may imply that the reionization of the universe has not been completed at z=6.5. We found that the spatial distribution of LAEs at z=6.5 was homogeneous over the field. We discuss the implications of these results for the reionization of the universe.

description: Methods for finding the optimal choices of the applied remote loads -- the applied normal force, moment, shear force and remote bulk stresses -- needed to solve frictional contact problems in partial-slip using half-plane theory are derived by using data from contacts analysed by the finite element method. While the normal and shear forces and moment are readily found from equilibrium considerations, in order to determine the bulk stresses we must exploit details of the traction ratio and the direct strain within the contact, both of which are readily extracted from simulations. These contact loads enable the formulation of an equivalent half-plane problem for the contact, which can be used to determine much more precise estimates of the slip-zone sizes than are obtainable from direct use of frictional finite element analysis, as aggregated data from the finite element output is employed, and the half-plane analysis will add precision in terms of satisfaction of the laws of frictional slip and stick.

description: Σκοπός της διατριβής ήταν να διερευνηθεί η επίδραση του α-ΜΕΑ και των ανταγωνιστών των υποδοχέων τύπου 1 της ANG-II στην έκκριση του t-PA και του ΡΑΙ-Ι, καθώς και στην δραστηριότητα των ΜΜΡs και των ΤΙΜΡs σε ιδιοπαθείς υπερτασικούς ασθενείς υπό θεραπεία με τα αντιϋπερτασιακά φάρμακα Per(α-ΜΕΑ) και Los και lrb. Συνολικά συμμετείχαν 8 υγιείς εθελοντές, ως μάρτυρες και 90 ασθενείς ήπιας υπέρτασης σταδίου 1 ή σταδίου 2. οι ασθενείς υποβλήθηκαν σε μονοθεραπεία με ένα εκ των ανωτέρω αντιϋπερτασικών φαρμάκων. Η δραστηριότητα ζελατινών μετρήθηκε με ζυμογραφία σε πήγμα ζελατίνης και ποσοτικοποίηση των ζωνών λύσης με πυκνομετρία σάρωσης, και τα επίπεδα πρωτεϊνης proMMP-1 TIMP, PAI-1 και tPA μετρήθηκαν με ανοσοενζυμογραφία, χρησιμοποιώντας συναγωνιστική ELISA. Διαπιστώθηκε ότι κατά την υπέρταση σταδίου 1 αυξάνονται τα επίπεδα πρωτεϊνης proMMP-2, η δραστηριότητα proMMP-2 και proMMP-9 και τα επίπεδα ΡΑΙ-1 στο πλάσμα, ενώ δεν επηρεάζονται τα επίπεδα TIMP-1, TIMP-2 και tPA. Οι σαρτάνες lrb και Los μειώνουν τη δραστηριότητα proMMP-2 και proMMP-9 και τα επίπεδα πρωτεϊνης της proMMP-2 και PAI-1, και αυξάνουν τα επίπεδα ΤΙΜΡ-1, ΤΙΜΡ-2 και tPA στο πλάσμα των ασθενών πριν την έναρξη θεραπείας. Ο α-ΜΕΑ Per μειώνει τα επίπεδα πρωτεϊνης της proMMP-2 και τη δραστηριότητα proMMP-2 και proMMP-9 στο πλάσμα, αλλά δεν επηρεάζει τα επίπεδα ΤΙΜΡ-1 και ΤΙΜΡ-2, ΡΑΙ-1 και tPA
description: The objective was to make a research concerning the effect of the ACE and the ARBs type I of ANG-II in the secretion of t-PA and PAI-1, as well as in the activity of MMPs and TIMPs in hypertensive patients who were treated with the Per, Los and Irb. A group of 8 healthy volunteers and 90 patients participated, who were diagnosed for essential hypertension. The patients were randomly subject to a monotreatment with one of the above-mentioned drugs. The gelatinolytic activity was measured and deteremined by gelatin zymography analysis and it was quantified using a computer-assisted image analysis program. The activity of the levels of proMMP-2 TIMP, PAI-1 and tPA were measured using the enzyme-linked immunosorbent ELISA assay. It was ascertained that during the primary and the secondary hypertension the levels of pro-MMP-2, the activity of the pro-MMP-2 and the pro-MMP-9 as well as the levels of PAI-1 in plasma are elevated, whereas the levels of TIMP-1, TIMP-2 and the tPA are not affected. The lrb and Los reduce the pro-MMP-2, pro-MMP-9 activity and the pro-MMP-2 and PAI-1 levels, while they increase the TIMP-1, TIMP-2 and tPA levels in plasma in comparison to the levels before the beginning of the treatment. The Per reduces the pro-MMP-2 levels and the pro-MMP-2 and pro-MMP-9 activity in the plasma, whereas the TIMP-1, TIMP-2 levels are not affected
