description: Στην παρούσα μελέτη ερευνήθηκε η κυτταροπλασματική κίνηση της τυροσίνης SYK, η έκφραση και ο ρόλος της στον καρκίνο του μαστού. Η έκφραση της SYK βρέθηκε να μειώνεται σημαντικά στα διηθητικά καρκινώματα και να εξαφανίζεται στα ενδοαγγειακά έμβολα. Θετική συσχέτιση της έκφρασης της SYK και γνωστών προγνωστικών δεικτών του καρκίνου του μαστού βρέθηκε σε πολλές περιπτώσεις. H SYK βρέθηκε να σχετίζεται άμεσα με την έκφραση του υποδοχέα β της ιντερλευκίνης 8 σε καρκινικές κυτταρικές σειρές. Μηχανισμός του οποίου η ρύθμιση μπορεί να ευθύνεται για την παρεμπόδιση της μετανάστευσης καρκινικών κυττάρων από την SYK. Η SYK βρέθηκε ουβικιτινυλιωμένη σε υψηλότερα επίπεδα στον καρκινικό σε σχέση με το διπλανό φυσιολογικό ιστό. Προτεινόμενη διαδικασία της μείωσης της έκφρασης της SYK στον καρκίνο του μαστού
description: In the present work, protein tyrosine kinase SYK was studied. Its repression and role was investigate in breast cancer patients as well as in a pane of breast cancer cell lines. SYK's expression was found very low in invasive breast carcinomas and undetectable in intravenous clots. Positive correlations between SYK and unknown prognostic namers was found in many cases. There was a direct effect of SYK's role in IL8RB expression in cancer cell lines regulation of which could accound for the inhibition of migration og cancer cells by SYK. SYK was found ubiguitinated, in higher levles in the cancerous compared with the nornal breast tissue. Ubiquitination and its disregulation, could account for the loss of SYK's expression seen in invasive breast cancers

description: We consider a prototypical nonlinear parabolic equation whose flux has three distinguished features: it is nonlinear with respect to both the unknown and its gradient, it is homogeneous, and it depends only on the direction of the gradient. For such equation, we obtain existence and uniqueness of entropy solutions to the Dirichlet problem, the homogeneous Neumann problem, and the Cauchy problem. Qualitative properties of solutions, such as finite speed of propagation and the occurrence of waiting-time phenomena, with sharp bounds, are shown. We also discuss the formation of jump discontinuities both at the boundary of the solutions' support and in the bulk.
Social identity reconstruction through education : a program for older women

description: A substantial number of older women are adversely affected by mild to severe levels of depression. In this study the Social Health Outreach Program (SHOP), an educational intervention originally developed for middle-aged women, was modified and implemented with depressed and non-depressed older women. Through an educative process, participants learned ways to strengthen personal social networks as a means of augmenting social identity and overcoming depression. The purposes of the study were: 1) to measure the impact of SHOP on older women's levels of depression and demoralization, and on their social networks; 2) to determine factors either within or outside of SHOP that helped or hindered their progress during the program; and 3) to describe and analyze their experience of depression. A total of 15 women, aged 58 to 76, participated in a 20 session version of SHOP over a ten week period. Measures of depression and demoralization were obtained before, after and three months following the program; social networks measures were also obtained at three month follow-up. Participants' perceptions about their experience of depression, and about program factors and other concurrent aspects of life that helped or hindered their progress during the program, were obtained in post-program interviews. Outcomes validated SHOP'S approach and demonstrated that with slight modification the program is as effective with older women as it is with mid-life women. Participants who were depressed at pre-test showed a significant decline in depression scores; on measures of demoralization, changes were in the direction expected, although non-significant. Participants reported significant gains to their social networks in terms of people and groups added. Content analysis of interview data yielded 205 helping incidents and 130 hindering incidents that occurred during the program period; from these, 20 categories of factors that advanced participants' progress during the program, and 19 categories of factors that impeded their progress, were determined. This study supported the view that for many older women depression originates in their social environment. The findings validated SHOP'S educational program as a means of increasing social participation, re-constructing social identity and overcoming depression.

description: We discuss strength of monopole excitation of the ground state to cluster states in light nuclei. We clarify that the monopole excitation to cluster states is in general strong as to be comparable with the single particle strength and shares an appreciable portion of the sum rule value in spite of large difference of the structure between the cluster state and the shell-model-like ground state. We argue that the essential reasons of the large strength are twofold. One is the fact that the clustering degree of freedom is possessed even by simple shell model wave functions. The detailed feature of this fact is described by the so-called Bayman-Bohr theorem which tells us that SU(3) shell model wave function is equivalent to cluster model wave function. The other is the ground state correlation induced by the activation of the cluster degrees of freedom described by the Bayman-Bohr theorem. We demonstrate, by deriving analytical expressions of monopole matrix elements, that the order of magnitude of the monopole strength is governed by the first reason, while the second reason plays a sufficient role in reproducing the data up to the factor of magnitude of the monopole strength. Our explanation is made by analysing three examples which are the monopole excitations to the $0^+_2$ and $0^+_3$ states in $^{16}$O and the one to the $0^+_2$ state in $^{12}$C. The present results imply that the measurement of strong monopole transitions or excitations is in general very useful for the study of cluster states.

description: We present an optical conductivity study of the multifold semimetal PdGa, performed in a broad spectral range (100 - 20000 cm-1; 12 meV - 2.5 eV) down to T = 10 K. The conductivity at frequencies below 4000 cm-1 is dominated by free carriers while at higher frequencies interband transitions provide the major contribution. The spectra do not demonstrate a significant temperature evolution: only the intraband part changes as a function of temperature with the plasma frequency remaining constant. The interband contribution to the conductivity exhibits a broad peak at around 5500 cm-1 and increases basically monotonously at frequencies above 9000 cm-1. The band-structure-based computations reproduce these features of the interband conductivity and predict its linear-in-frequency behavior as frequency diminishes.

description: New THz data on the optical conductivity of Pb are presented as well as a detailed Eliashberg analysis with particular emphasis on phonon-assisted processes not included in a BCS approach. Consideration of the optical self-energy instead of the conductivity itself helps highlight the differences with BCS predictions. Predicted coherence peaks are observed in the optical scattering rates. Impurities enhance the optical effective mass at zero frequency by an order of magnitude and induce a large peak at twice the gap in agreement with theory. This work illustrates the usefulness of the optical self-energy for the analysis of data.

description: Intrinsic bugs are bugs for which a bug introducing change can be identified in the version control system of a software. In contrast, extrinsic bugs are caused by external changes to a software, such as errors in external APIs; thereby they do not have an explicit bug introducing change in the version control system. Although most previous research literature has assumed that all bugs are of intrinsic nature, in a previous study, we show that not all bugs are intrinsic. This paper shows an example of how considering extrinsic bugs can affect software engineering research. Specifically, we study the impact of extrinsic bugs in Just In Time bug prediction by partially replicating a recent study by McIntosh and Kamei on JIT models. These models are trained using properties of earlier bug-introducing changes. Since extrinsic bugs do not have bug introducing changes in the version control system, we manually curate McIntosh and Kamei's dataset to distinguish between intrinsic and extrinsic bugs. Then, we address their original research questions, this time removing extrinsic bugs, to study whether bug-introducing changes are a moving target in Just-In-Time bug prediction. Finally, we study whether characteristics of intrinsic and extrinsic bugs are different. Our results show that intrinsic and extrinsic bugs are of different nature. When removing extrinsic bugs the performance is different up to 16 % Area Under the Curve points. This indicates that our JIT models obtain a more accurate representation of the real world. We conclude that extrinsic bugs negatively impact Just-In-Time models. Furthermore, we offer evidence that extrinsic bugs should be further investigated, as they can significantly impact how software engineers understand bugs.

description: The objective of this study was to develop a novel quantitative EEG(qEEG) based analysis method in order to detect potential EEG changes of patients admitted to the ICU with acute respiratory failure and correlate them to the patients' recovery outcome, in order to predict the optimal wearing from the ventilator. Twenty nine adult patients with acute respiratory failure admitted to the Intensive Care Unit of Saint Paul General Hospital were enrolled, and among them only fifteen completed the study. The patients were intubation, FiO2 was decreased to 40% followed by a swin early recovery session, a swin recovery 1 session and a swin recovery 2 session during which the actual measurements were performed multichannel EEG measurements were processed of approximate entropy and of detrended fluctuation analysis. A statistically significant increase of GFDT and decrease of approximate entropy during weaning session was observed in the subjects. Comparing the three patients' groups, statistically significant differences for GFDT were observed for the meaning and the early revovery session. Conclusively quantitative EEG seems to be an, important tool for ICU clinicians, assisting them to decide for the patients' optimal wearing from the ventilator

description: In this study, issues related to information processing and management in distributed medical information systems were addressed by proposing autonomous software agents as the technological solution. Autonomous agents constitute an alternative approach for the design and development of complex software systems. First, a cooperating software agent community was designed to cope with dynamic and asynchronous data flow management, which was applied in a Medical Contact Centre. In the following, a methodology for integration of heterogeneous and distributed biomedical systems was developed, which was applied in gene prediction tools, that are available in the World Wide Web. Finally, an approach for dynamic composition of information sources, in order to develop an integrated information space, through agents, was proposed and applied with gene prediction services. The proposed approaches indicated the use and virtue of the software agent metaphor for designing and developing distributed biomedical systems

description: Over the last few years, the European Commission has repeatedly emphasized that, in the face of global uncertainty, the EU has to strengthen its social dimension and foster better working and living conditions for its citizens. To achieve this, the EU wants to strengthen social citizenship by advancing social rights, implementing the principles in the European Pillar of Social Rights at both the European and national level. The overarching objective of the EuSocialCit project, of which this paper is part, is to examine the state of EU social citizenship as well as possible policy scenarios that may strengthen it. This prompts initial foundational questions for the project: what is the nature of EU social citizenship and the social rights associated with it? And, what is the rationale for the EU to be involved in providing social rights? In order to understand the state and nature of EU social citizenship and the role that the EU plays in this now and in the future, we believe that it is necessary to ‘dissect’ the constitutive elements of social rights at the various levels (local, national and EU) at which they are provided. To this end, this paper develops a resource-based and multi-level conception of social rights. With regard to the rationale, we offer an overview of the main approaches that prevail in the long-standing debate on the justification and feasibility of a stronger EU social citizenship and present a synthesis of these approaches that may help further the debate.
X-ray and HeI 1.0830 mu emission from protostellar jets
Creators: name: Liseau, R.
Publisher: name: arXiv
Year: 2006

subject: FOS: Physical sciences

description: Context. The high energies of protostellar jets, implied by recent observations of X-rays from such flows, came very much as a surprise. Inferred shock velocities are considerably higher than what was previously known, hence putting even larger energy demands on the driving sources of the jets. The statistics of X-ray emitting jets are still poor, yet a few cases exist which seem to imply a correlation between the presence of HeI 1.0830 mu emission and X-ray radiation in a given source. Aims. This tentative correlation needs confirmation and explanation. If the jet regions of HeI 1.0830 mu emission are closely associated with those producing X-rays, high resolution infared spectroscopy can be used to observationally study the velocity fields in the hot plasma regions of the jets. This would provide the necessary evidence to test and further develop theoretical models of intermediately fast (> 500 - 1500 km/s) interstellar shock waves. Methods. The HH 154 jet flow from the embedded protostellar binary L 1551 IRS 5 provides a case study, since adequate IR and X-ray spectroscopic data are in existence. The thermal X-ray spectrum is fed into a photoionization code to compute, in particular, the line emission of HeI and HI and to account for the observed unusual line intensity ratios. Results. The advanced model is capable of accounting for most observables, but shows also major weaknesses. It seems not unlikely that these could, in principle, be overcome by a time dependent hydrodynamical calculation with self-consistent cooling. However, such sophisticated model development is decisively beyond the scope of the present work. Conclusions. Continued X-ray observations, coordinated with simultaneous high resolution infrared spectroscopy, are highly desirable.

description: Cumulative lifetime effects of noise exposure may or may not be related to reduced performance in speech in noise tests or elevated audiometric thresholds. In addition, some effects of noise-induced hearing impairment may be evident at the neural level, such as cochlear synaptopathy, but not necessarily be observable as raised hearing thresholds of the typical audiogram (often testing sound frequencies between 0.25 and 8 kHz). Individuals' experience of noise exposure is often difficult to measure, but a structured interview approach may prove useful in eliciting information regarding noise exposure across a range of noise exposure activities.

In the current study, the association between a participants' self-report of noise exposure and awareness of difficulties in following speech in ongoing noise were compared with their performance on the Matrix speech-in-noise test. The Matrix test is an adaptive speech-in-noise test using a larger speech corpus than other commonly used tests. All participants had hearing thresholds within normal limits, were assessed on their past history of noise exposure, and asked about their ease/difficulties following speech in ongoing noise.

For each participant, the Matrix test measures were fitted with psychometric intelligibility functions. The deduced intelligibility function parameters, i.e., speech reception threshold (SRT) and function slope, were compared with self-reported score of difficulties with speech intelligibility in noise and past noise exposure history. These resultant associations are discussed with reference to intra- and inter-participant variances in self-report of perceived difficulty and recall of noise experiences.

description: Initially novel techniques of mining uncertainty rules for numerical and multimedia medical databases have developed by this study. These databases were mostly coming from a home cave monitoring system. Consequently, these techniques were extended to became a preprocessing method for filling randomly missing values. In particularly, the three uncertainty rule algorithms are : a)the URG algorithm is referred to numerical medical data being able to deal with missing values internally and mining rules incrementally b)the AURG algorithm is a progress of URG algorithm using an adaptive threshold c)the RDA algorithm mines uncertainty rules appropriate for multimedia medical data, as ECGs. The study has completed though the expansion of the above uncertainty rule algorithms ints two novel preprocessing methods for filling missing values

description: Κύριος στόχος της διατριβής είναι η αναγνώριση και ερμηνεία των προτύπων της δυναμικής του φυτοπλαγκτού και του βακτηριοπλαγκτού και η αναγνώριση της σύζευξης μεταξύ των δύο αυτών λειτουργικών ομάδων στην παραγωγή νέου οργανισμού άνθρακα για τη στήριξη του τροφικού πλέγματος σε ένα ιδιαίτερο εύτροφο σύστημα στον Ορμο Θεσσαλονίκης, την περίοδο Δεκέμβριος 1996-Ιούνιος 1998. Στο ιδιαίτερα εύστροφο σύστημα της περιοχής μελέτης παρατηρήθηκαν συχνές ανθίσεις φυτοπλαγκτού και υψηλές τιμές παραγωγικότητας φυτοπλαγκτού. Το βακτηριοπλαγκτό αποτελεί συμπληρωμαιτκό προς το φυτοπλαγκτό παραγωγό σωματιδιακού οργανικού άνθρακα και κατά περιόδους η βιομάζα του κυριαρχεί αυτής του φυτοπλαγκτού με αποτέλεσμα την εμφάνιση ανάστροφης πυραμίδας στο πλαγκτικό τροφικό πλέγμα. Αναγνωρίσθηκε σύζευξη μεταξύ της παραγωγικότητας του βακτηριοπλαγκτού και της παραγωγικότητας του φυτοπλαγκτού η οποία φαίνεται ισχυρότερη τις περιόδους με χαμηλές τιμές παραωγικότητας φυτοπλαγκτού. Η υψηλή παραγωγικότητα του βακτηριοπλαγκτού τροφοδοτεί ένα ισχυρό βρόγχο στο πελαγικό τροφικό πλέγμα
description: This dissertation aims to the identification and study of phytoplankton and bacterioplankton biomass dynamics and of the coupling between these two functional groups in the production of newly synthesized organic carbon at the base of the food web in an especially eutophic system in the Bay of Thessaloniki. In this system, blooms of phytoplankton were frequently observed and phytoplankton productivity reached high values. Bacterioplankton supplements phytoplankton in the production of particulate organic carbon and at times its biomass is higher than that of phytoplantkon resulting in inverted biomass pyramid in the plantic food web. The coupling between the productivity of bacterioplankton and that of phytoplankton was identified. This coupling seems stronger at lower values of phytoplankton productivity. Productivity of bacterioplankton was found in high values and seems to support a strong microbial loop of the pelagic food web

description: The properties of the gas in halos of galaxies constrain global models of the interstellar medium. Kinematical information is of particular interest since it is a clue to the origin of the gas. Here we report observations of the kinematics of the thick layer of the diffuse ionized gas in NGC 891 in order to determine the rotation curve of the halo gas. We have obtained a Fabry-Pérot data cube in Halpha to measure the kinematics of the halo gas with angular resolution much higher than obtained from HI 21 cm observations. The data cube was obtained with the TAURUS II spectrograph at the WHT on La Palma. The velocity information of the diffuse ionized gas extracted from the data cube is compared to model distributions to constrain the distribution of the gas and in particular the halo rotation curve. The best fit model has a central attenuation tau_H-alpha=6, a dust scale length of 8.1 kpc, an ionized gas scale length of 5.0 kpc. Above the plane the rotation curve lags with a vertical gradient of -18.8 km/s/kpc. We find that the scale length of the H-alpha must be between 2.5 and 6.5 kpc. Furthermore we find evidence that the rotation curve above the plane rises less steeply than in the plane. This is all in agreement with the velocities measured in the HI.

description: In a previous work, we proved an existence result for BSDEs with quadratic generators with respect to the variable z and with unbounded terminal conditions. However, no uniqueness result was stated in that work. The main goal of this paper is to fill this gap. In order to obtain a comparison theorem for this kind of BSDEs, we assume that the generator is convex with respect to the variable z. Under this assumption of convexity, we are also able to prove a stability result in the spirit of the a priori estimates stated in the article of N. El Karoui, S. Peng and M.-C. Quenez. With these tools in hands, we can derive the nonlinear Feynman--Kac formula in this context.

description: We find a novel confinement mechanism in the two-flavor dense quark matter proposed recently, that consists of the 2SC condensates and the $P$-wave diquark condensates of $d$-quarks. This quark matter exhibiting color superconductivity as well as superfluidity is classified into two phases; confined and deconfined phases of vortices. We establish that the criterion of the confinement is color neutrality of Aharonov-Bohm (AB) phases: vortices exhibiting color non-singlet AB phases are confined by the so-called AB defects to form color-singlet bound states. In the deconfined phase, the most stable vortices are non-Abelian Alice strings, which are superfluid vortices with fractional circulation and non-Abelian color magnetic fluxes therein, exhibiting color non-singlet AB phases. On the other hand, in the confined phase, these non-Abelian vortices are confined to either a baryonic or mesonic bound state in which constituent vortices are connected by AB defects. The baryonic bound state consists of three non-Abelian Alice strings with different color magnetic fluxes with the total flux canceled out connected by a domain wall junction, while the mesonic bound state consists of two non-Abelian Alice strings with the same color magnetic fluxes connected by a single domain wall. Interestingly, the latter contains a color magnetic flux in its core, but this can exist because of color neutrality of its AB phase.

description: This paper exhibits a duality between the theory of Revealed Preference of Afriat and the housing allocation problem of Shapley and Scarf. In particular, it is shown that Afriat's theorem can be interpreted as a second welfare theorem in the housing problem. Using this duality, the revealed preference problem is connected to an optimal assignment problem, and a geometrical characterization of the rationalizability of experiment data is given. This allows in turn to give new indices of rationalizability of the data, and to define weaker notions of rationalizability, in the spirit of Afriat's efficiency index.

description: Η διατριβή επιχειρεί να μελετήσει τις βασικές δομικές αλλαγές που λαμβάνουν χώρα κατά τη μεταφορά ενός λογοτεχνικού έργου στον κινηματογράφο. Ειδικότερα διερευνά το κατά πόσο τα αφηγηματικά στοιχεία της φωνής και εστίασης ενυπάρχουν στα κινηματογραφικά κείμενα και αποτελούν, όπως στη λογοτεχνία, σημαντικά μέσα όσον αφορά στη διαμόρφωση της γνώσης του θεατή. Με βάση λογοτεχνικές κυρίως θεωρίες(Barthes, Greimas, Genette) συγκρίναμε τις τέσσερις κινηματογραφικές μεταφορές του επιστολικού μυθιστορήματος "Les liaisons dangereuses" του Choderlos de Lacros με τη λογοτεχνική πηγή

description: We consider diffusion type equations with a distributed order derivative in the time variable. This derivative is defined as the integral in $α$ of the Caputo-Dzhrbashian fractional derivative of order $α\in (0,1)$ with a certain positive weight function. Such equations are used in physical literature for modeling diffusion with a logarithmic growth of the mean square displacement. In this work we develop a mathematical theory of such equations, study the derivatives and integrals of distributed order.

description: In this paper we consider the rôle that numerical computations -- in particular Galerkin approximations -- can play in problems modelled by the 3d Navier-Stokes equations, for which no rigorous proof of the existence of unique solutions is currently available. We prove a robustness theorem for strong solutions, from which we derive an {\it a posteriori} check that can be applied to a numerical solution to guarantee the existence of a strong solution of the corresponding exact problem. We then consider Galerkin approximations, and show that {\it if} a strong solution exists the Galerkin approximations will converge to it; thus if one is prepared to assume that the Navier-Stokes equations are regular one can justify this particular numerical method rigorously. Combining these two results we show that if a strong solution of the exact problem exists then this can be verified numerically using an algorithm that can be guaranteed to terminate in a finite time. We thus introduce the possibility of rigorous computations of the solutions of the 3d Navier-Stokes equations (despite the lack of rigorous existence and uniqueness results), and demonstrate that numerical investigation can be used to rule out the occurrence of possible singularities in particular examples.

Διαιρείται σε τρεις περιόδους(1839-1900, 1900-1950, 1950-2000) και εξετάζει το τόπο και τη φωτογραφική του εικόνα ως πολιτισμική κατασκευή που επηρεάζεται από τις συμβάσεις της τέχνης. Το υλικό που εξετάστηκε, ανάλογα με τα ιδιαίτερα χαρακτηριστικά κάθε περιόδου, περιλάμβανε τόσο πρωτότυπες φωτογραφίες και λευκώματα, όσο και εκδόσεις και εικονογραφημένα περιοδικά που δείχνουν τη φωτογραφία του τοπίου ως μαζική εικονογραφία. Η φωτογραφία του ελλην. τοπίου αποδεικνύεται τελικά σημαντική για την εδραίωση της εθνικής ταυτότητας και άλλων εθνικών στόχων(π.χ. τουρισμός)υπακούοντας ανά περίοδο σε συγκεκριμένα στερότυπα : τόπο ερειπίων, βουκολικό, αιγαιακό.

description: The research surveys the photography of greek landscape from 1839 until today, in three periods(1839-1900, 1900-1950, 1950-2000) in which the landscape and its photographic image are viewed as cultural constructions, influenced examined, taking into account the special features of each period, included original photographs and albums, as well as publications and illustrated magazines that show landscape photography as mass iconography. The photograph of the greek landscape proves finally important for the foundation of national identity and other goals(e.g. tourism) following specific stereotypes in each period : ruins, bucolic, aegean landscape. At the same moment it hides the real image of the century. It also proves fertile ground for the introduction of western ideological views and aesthetic idioms that are applied to the landscape
