description: We present a catalog of 110 variable stars within ~1' of Sgr A* based on image subtraction of near-infrared (H and K) photometry. Our images were obtained over 133 nights from 2000--2002 in H-band and over 134 nights from 2001--2002 in K-band; the typical FWHM is 1.4''. We match the catalog to other near-infrared, X-ray, and radio (i.e., maser) data, and we discuss some of the more interesting objects. The catalog includes 14 periodic sources, several known long-period variables and three new LPV candidates. We associate IRS 10* with OH, SiO, and H2O masers and a bright X-ray point source; this analysis suggests IRS 10* is an AGB star with an accreting companion. Among the approximately 90 newly discovered sources are a probable cataclysmic variable, a potential edge-on contact 84 day period eclipsing binary, and a possible 41 day period pulsating variable.

The role of the therapeutic allance in the treatment of alcoholic famlies
Creators: name: Olson, Gregory Scott
Publisher: name: University of British Columbia
Year: 2009

description: This study was part of a larger one called The Alcohol Recovery Project. The overarching aim of the present investigation was to broaden understanding regarding the role of the therapeutic alliance in the treatment of alcoholics within a systemic perspective. Using Pinsof and Catherall’s (1986) conceptualization of the affiance, a process-outcome study was conducted within both individual and conjoint formats. A sample of 63 alcoholic men and 21 non-alcoholic female partners was divided into three different treatment groups, two for individuals and one for couples. Several aspects of the affiance were investigated including: (a) the strength of the alliance in different treatments; (b) the impact of drinking behavior on the alliance; (c) the differential power of the affiance in predicting outcome in the individual therapeutic format compared to the conjoint one; (d) the impact of gender on alliance strength; and (e) the relationship between split amd intact affiances and therapeutic improvement. Results of the study indicated: (a) that the strength of the affiance was nearly identical in two very different therapeutic approaches; (b) that binge and chronic alcohol-use patterns served as potent predictors of the correlation between alliance and dyadic adjustment gain; (c) that the strength of the relationship between the affiance and therapeutic gain was not significantly different in individual as opposed to conjoint treatment (recognizing limitations in using the scales to compare modalities); (d) that women formed significantly stronger affiances than men; and (e) that the theoretical constructs of split and intact alliances could be empirically identified. The complexities inherent in interpreting results surrounding a process variable like the affiance became very evident as did the need for more study of the construct. Implications of the results were discussed, and recommendations made for future directions of research.

description: As more applications are being moved to the Cloud thanks to serverless computing, it is increasingly necessary to support the native life cycle execution of those applications in the data center. But existing cloud orchestration systems either focus on short-running workflows (like IBM Composer or Amazon Step Functions Express Workflows) or impose considerable overheads for synchronizing massively parallel jobs (Azure Durable Functions, Amazon Step Functions). None of them are open systems enabling extensible interception and optimization of custom workflows. We present Triggerflow: an extensible Trigger-based Orchestration architecture for serverless workflows. We demonstrate that Triggerflow is a novel serverless building block capable of constructing different reactive orchestrators (State Machines, Directed Acyclic Graphs, Workflow as code, Federated Learning orchestrator). We also validate that it can support high-volume event processing workloads, auto-scale on demand with scale down to zero when not used, and transparently guarantee fault tolerance and efficient resource usage when orchestrating long running scientific workflows.

description: Σκοπός της διατριβής ήταν η μελέτη των παγιωμένων εκφράσεων της νεοελληνικής γλώσσας. Εξετάσαμε την ορολογία που χρησιμοποιείται για τις παγιωμένες εκφράσεις και τους ορισμούς που έχουν προταθεί. Στη συνέχεια παρουσιάσαμε αναλυτικά τα χαρακτηριστικά των παγιωμένων εκφράσεων, καθώς και τους περιορισμούς που ισχύουν όσον αφορά το λεξιλόγιο, τη γραμματική και τη σύνταξή τους. Ακόμη αναφερθήκαμε αναλυτικά στα μοντέλα κατανόησης των παγιωμένων εκφράσεων που έχουν προταθεί και μας απασχόλησε η κατανόηση των παγιωμένων εκφράσεων από τα παιδιά καθώς και η διδασκαλία τους σε ξενόγλωσσους. Ένα άλλο θέμα που θίξαμε ήταν η συγγραφή λεξικών παγιωμένων εκφράσεων και παρουσιάσαμε ορισμένα που έχουν γραφεί για την ελληνική. Ασχοληθήκαμε επιπλέον με την ιστορική διάσταση των παγιωμένων εκφράσεων της νέας ελληνικής και διαπιστώσαμε την παρουσία τους από την αρχαιότητα μέχρι σήμερα. Ένα βασικό συμπέρασμα της έρευνας είναι ότι οι σύγχρονες ελληνικές επιχειρήσεις οφείλουν να ενσωματώσουν τις καταναλωτικές επιθυμίες και τις προσδοκίες των καταναλωτών σε μεγαλύτερο βαθμό.

description: The aim of the present thesis was the study of frozen expressions (idioms) in Modern Greek. We examined the proposed terminology and the definitions given for frozen expressions. Then we presented the features of frozen expressions and the restrictions on vocabulary, grammar, and syntax. Furthermore, we analyzed the models concerning the comprehension of frozen expressions and we examined children’s ability to produce and understand frozen expressions as well as ways of teaching them to foreign learners. We also examined the compilation of dictionaries of frozen expressions and we presented selected Greek dictionaries written in the last two decades. Another aim of this study was to examine the historical dimension of frozen expressions. A key finding of the study is that contemporary Greek businesses need to integrate further within their promotional activities, consumers’ desires and expectations in order to achieve their marketing objectives. Social media is a vehicle for attracting new customers and retaining existing ones

The nature and evolution of the highly ionized near-zones in the absorption spectra of z~6 quasars
Creators: name: Bolton, James S.

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

description: We use state-of-the-art hydrodynamical simulations combined with a 1D radiative transfer code to assess the extent to which the highly ionized regions observed close to z~6 quasars, which we refer to as near-zones, can constrain the ionization state of the surrounding IGM. We find the appearance in Lya absorption of a quasar HII ionization front expanding into a neutral IGM can be very similar to a classical proximity zone, produced by the enhancement in ionizing flux close to a quasar embedded in a highly ionized IGM. The observed sizes of these highly ionized near-zones and their redshift evolution can be reproduced for a wide range of IGM neutral hydrogen fractions for plausible values of the luminosity and lifetime of the quasars. The observed near-zone sizes at the highest observed redshifts are equally consistent with a significantly neutral and a highly ionized surrounding IGM. Stronger constraints on the IGM neutral hydrogen fraction can be obtained by considering the relative size of the near-zones in the Lya and Lyb regions of a quasar spectrum. A large sample of high quality quasar absorption spectra with accurate determinations of near-zone sizes and their redshift evolution in both the Lya and Lyb regions should confirm or exclude the possibility that the Universe is predominantly neutral at the highest observed redshifts. The width of the discrete absorption features in these near-zones will contain important additional information on the ionization state and the previous thermal history of the IGM at these redshifts.

description: The Coma cluster is the richest and most compact of the nearby clusters, yet there is growing evidence that its formation is still on-going. With a new multi-slit imaging spectroscopy technique pioneered at the 8.2 m Subaru telescope and FOCAS, we have detected and measured the line-of-sight velocities of 37 intracluster planetary nebulae associated with the diffuse stellar population of stars in the Coma cluster core, at 100 Mpc distance. We detect clear velocity substructures within a 6 arcmin diameter field. A substructure is present at ~5000 km/s, probably from in-fall of a galaxy group, while the main intracluster stellar component is centered around ~6500 km/s, ~700 km/s offset from the nearby cD galaxy NGC 4874. The kinematics and morphology of the intracluster stars show that the cluster core is in a highly dynamically evolving state. In combination with galaxy redshift and X-ray data this argues strongly that the cluster is currently in the midst of a subcluster merger, where the NGC 4874 subcluster core may still be self-bound, while the NGC 4889 subcluster core has probably dissolved. The NGC 4889 subcluster is likely to have fallen into Coma from the eastern A2199 filament, in a direction nearly in the plane of the sky, meeting the NGC 4874 subcluster arriving from the west. The two inner subcluster cores are presently beyond their first and second close passage, during which the elongated distribution of diffuse light has been created. We predict the kinematic signature expected in this scenario, and argue that the extended western X-ray arc recently discovered traces the arc shock generated by the collision between the two subcluster gas halos. Any preexisting cooling core region would have been heated by the subcluster collision.

Bilayer graphene encapsulated within monolayers of WS$_2$ or Cr$_2$Ge$_2$Te$_6$: Tunable proximity spin-orbit or exchange coupling

description: Van der Waals (vdW) heterostructures consisting of bilayer graphene (BLG) encapsulated within monolayers of strong spin-orbit semiconductor WS$_2$ or ferromagnetic semiconductor Cr$_2$Ge$_2$Te$_6$ (CGT), are investigated. By performing realistic first-principles calculations we capture the essential BLG band structure features, including layer- and sublattice-resolved proximity spin-orbit or exchange couplings. For different relative twist angles (0 or 60$^{\circ}$) of the WS$_2$ layers, and the magnetizations (parallel or antiparallel) of the CGT layers, with respect to BLG, the low energy bands are found and characterized by a series of fit parameters of model Hamiltonians. These effective models are then employed to investigate the tunability of the relevant energy dispersions by a gate field. For WS$_2$/BLG/WS$_2$ encapsulation we find that twisting allows to turn off the spin splittings away from the $K$ points, due to opposite proximity-induced valley-Zeeman couplings in the two sheets of BLG. Close to the $K$ points the electron spins are polarized out of the plane. This polarization can be flipped by applying a gate field. As for magnetic CGT/BLG/CGT structures, we realize the recently proposed spin-valve effect, whereby a gap opens for antiparallel magnetizations of the CGT layers. Furthermore, we find that for the antiferromagnetic orientation the electron states away from $K$ have vanishingly weak proximity exchange, while the states close to $K$ remain spin polarized in the presence of an electric field. The induced magnetization can be flipped by changing the gate field. These findings should be useful for spin transport, spin filtering, and spin relaxation anisotropy studies of BLG-based vdW heterostructures.

description: This work analyzes resonance frequency shift vs. the applied magnetic field strength for GHz operating GaN/Si SAW single resonators. Magnetostrictive elements (Ni and CoFeB) were deposited in the proximity of the interdigitated transducers (IDTs) of the resonators (A-type structures) and also over the IDTs, after covering them with a BCB layer to avoid short circuits with IDTs metal (B-type structures). This work targets emerging applications of SAW resonators in driving spin wave pumping and in coupling of surface acoustic waves (SAW) with superconducting Q-bits. Magnetic sensitivity of the SAWs was analyzed at room temperature (RT) and at cryogenic temperatures, obtaining high magnetic sensitivities at 16 K. According to our knowledge, GaN based SAWs are first time used in magnetic applications; also, cryogenic behavior of magnetic SAW sensors is first time analyzed.

description: Black-body radiation, omnipresent at room temperature, couples nearby Rydberg states. The resulting state mixture features strong dipolar interactions, which may induce dephasing in a Rydberg many-body system. Here we report on a single atom resolved study of this state contamination and the emerging pairwise interactions in optical tweezers. For near-resonant laser detuning we observe characteristic correlations with a length scale set by the dipolar interaction. Our study reveals the microscopic origin of avalanche excitation observed in previous experiments.
Children of alcoholics:the relationship between paternal pattern of drinking and children’s experience of family
Creators: name: Bate, Cheryl A.
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the relationship between fathers’ pattern of drinking and children’s perceptions of family functioning. The study included 110 children, aged 9-20, who lived in the homes of, or were closely connected to, their alcohol-involved families. The pattern of fathers’ drinking (irregular versus steady) was determined, and standardized instruments were employed to measure central aspects of family life, including, parent-child communication; family adaptability and cohesion; family environment; family social support; and family satisfaction. A multivariate analysis of covariance was performed on the data, with age as a covariate, to determine if significant differences existed between the two groups of children. A multiple regression analysis then was conducted to determine which factors accounted for the most variability between children of irregular drinking homes and children of steady drinking homes. The differences between the groups were striking, with children of irregular drinking homes reporting significantly less togetherness, organization, cohesion, satisfaction, social support and communication; and significantly more chaos, conflict and control than children in steady drinking homes. Children’s experience of family adaptability, control, expressiveness and satisfaction were the variables that accounted for most of the differences between these two subtypes of alcoholic families.

description: Let $f\in L^2(S^2)$ be an arbitrary fixed function with small norm on the unit sphere $S^2$, and $D\subset \R^3$ be an arbitrary fixed bounded domain. Let $k>0$ and $α\in S^2$ be fixed. It is proved that there exists a potential $q\in L^2(D)$ such that the corresponding scattering amplitude $A(α')=A_q(α')=A_q(α',α,k)$ approximates $f(α')$ with arbitrary high accuracy: $\|f(α')-A_q(α')_{L^2(S^2)}\|\leq\ve$ where $\ve>0$ is an arbitrarily small fixed number. This means that the set $\{A_q(α')\}_{\forall q\in L^2(D)}$ is complete in $L^2(S^2)$. The results can be used for constructing nanotechnologically "smart materials".

description: Bound states in the continuum (BICs) enable unique features in tailoring light-matter interaction on nanoscale. These radiationless localized states drive theoretically infinite quality factors and lifetimes for modern nanophotonics, making room for a variety of emerging applications. Here we use the peculiar properties possessed by the so-called $\mathcal{PT}$-symmetric optical structures to propose the novel mechanism for the quasi-BIC manifestation governed by the $\mathcal{PT}$-symmetry breaking. In particular, we study regularities of the spontaneous $\mathcal{PT}$-symmetry breaking in trilayer structures with the outer loss and gain layers consisting of materials with permittivity close to zero. We reveal singular points on the curves separating $\mathcal{PT}$-symmetric and broken-$\mathcal{PT}$-symmetry states in the parametric space of the light frequency and the angle of incidence. These singularities remarkably coincide with the BIC positions at the frequency of volume plasmon excitation, where the dielectric permittivity vanishes. The loss and gain value acts as an asymmetry parameter that disturbs conditions of the ideal BIC inducing the quasi-BIC. Fascinating properties of these quasi-BICs having ultrahigh quality factors and almost perfect transmission can be utilized in sensing, nonlinear optics, and other applications.

description: An inherent problem that entrepreneurs face in the beginning of their entrepreneurial initiative is attracting outside capital, given the lack of collateral and sufficient cash flows and the presence of significant information asymmetry with investors. Recently, some entrepreneurs abroad have started to rely on crowdfunding instead of approaching financial investors such as business angels, banks or venture capital funds. With crowdfunding, an entrepreneur raises external financing from a large audience (the "crowd"), in which each individual provides a very small amount, instead of soliciting a small group of sophisticated investors. The Greek legislator in his effort to find alternative financing opportunities for Greek entrepreneurs and companies enacted the 4416/2016 law. This legislation amended some provision of 3401/2005 (“The Greek Prospectus Act”) and 3606/2007 (“Markets in Financial Instruments Act”) legislations, which are in fact the Greek regulation on crowdfunding. This is exactly what this dissertation will explore the regulatory framework of crowdfunding in Greece with a view to providing a general description of the newly adopted crowdfunding regulation.

Αυτό ακριβώς θα διερευνήσει η παρούσα εργασία, το ρυθμιστικό πλαίσιο του crowdfunding στην Ελλάδα με σκοπό να παράσχει μια γενική περιγραφή της σχετικά πρόσφατης νομοθεσίας για το crowdfunding.
Searching for the reionization sources

Subjects: subject: Astrophysics (astro-ph)

description: Using a reionization model simultaneously accounting for a number of experimental data sets, we investigate the nature and properties of reionization sources. Such model predicts that hydrogen reionization starts at z \approx 15, is initially driven by metal-free (PopIII) stars, and is 90% complete by z \approx 8. We find that a fraction f_γ>80% of the ionizing power at z > 7 comes from haloes of mass M<10^9 M_sun predominantly harbouring PopIII stars; a turnover to a PopII-dominated phase occurs shortly after, with this population, residing in M>10^9 M_sun haloes, yielding f_γ\approx 60% at z=6. Using Lyman-break broadband dropout techniques, J-band detection of sources contributing to 50% (90%) of the ionizing power at z \sim 7.5 requires to reach a magnitude J_{110,AB} = 31.2 (31.7), where about 15 (30) (PopIII) sources/arcmin^2 are predicted. We conclude that z>7 sources tentatively identified in broadband surveys are relatively massive (M \approx 10^9 M_sun) and rare objects which are only marginally (\approx 1%) adding to the reionization photon budget.

description: We present a new approach to the construction of effective interactions suitable for many-body calculations by means of the no-core shell model (NCSM). We consider an effective field theory (EFT) with only nucleon fields directly in the NCSM model spaces. In leading order, we obtain the strengths of the three contact terms from the condition that in each model space the experimental ground-state energies of 2H, 3H and 4He be exactly reproduced. The first (0^+;0) excited state of 4He and the ground state of 6Li are then obtained by means of NCSM calculations in several spaces and frequencies. After we remove the harmonic-oscillator frequency dependence, we predict for 4He an energy level for the first (0^+;0) excited state in remarkable agreement with the experimental value. The corresponding 6Li binding energy is about 70% of the experimental value, consistent with the expansion parameter of the EFT.

description: Σκοπός της διπλωματικής εργασίας είναι η μελέτη και παρουσίαση των νομικών ζητημάτων που άπτονται του δικαιώματος αναπαραγωγής των έργων πνευματικής ιδιοκτησίας και των περιορισμών του δικαιώματος αυτού. Αρχικά, επιχειρείται η έκθεση των σημαντικότερων διεθνών, ενωσιακών και εθνικών νομοθετικών κειμένων στα οποία ρυθμίζονται τα ζητήματα της πνευματικής ιδιοκτησίας, ενώ γίνεται και μία προσπάθεια εξοικείωσης του αναγνώστη με βασικές έννοιες του δικαίου της πνευματικής ιδιοκτησίας, όπως το «έργο», ο «δημιουργός» και το «ηθικό και περιουσιακό δικαίωμα του δημιουργού», που συνθέτουν το «δικαίωμα πνευματικής ιδιοκτησίας», με στόχο την καλύτερη κατανόηση των εξειδικευμένων εννοιών που ακολουθούν. Εν συνεχεία, δίδεται ο ορισμός του δικαιώματος αναπαραγωγής, αναλύεται η συσχέτιση των όρων «εγγραφή και αναπαραγωγή» και περιγράφονται οι διακρίσεις του εν λόγω δικαιώματος. Ακολούθως, το ενδιαφέρον μετακυλίεται στους περιορισμούς του δικαιώματος αναπαραγωγής μέσω αναλυτικής παρουσίασης τόσο των «κλασικών» περιορισμών, όσο και αυτών που σχετίζονται με τις νέες τεχνολογίες και η καθιέρωση των οποίων υπαγορεύθηκε βάσει των νέων δεδομένων. Τέλος, γίνεται μία σύντομη αναφορά στο δικαίωμα αναπαραγωγής και τους περιορισμούς αυτού στο πεδίο των συγγενικών δικαιωμάτων, ενώ παρατίθενται και ορισμένες τελικές παρατηρήσεις.
description: The aim of the present thesis is the study and presentation of the legal issues that pertain to the reproduction right of the authors’ creative works and the limitations of this right. At first, I present the most important international, european and national laws that regulate the issues related to the intellectual property and I try to acquaint the readers with basic terms of the copyright law, such as the «work», the «author» and the «moral and economic right of the author», that compose the «intellectual property right», in order the readers to be able to comprehend the following technical terms. Furthermore, I define the reproduction right, I analyze the association between «recording and reproduction» and I describe the division of the reproduction right. What is more, I expound on the limitations of the reproduction right, analyzing both the «conventional» and the new technological limitations, the legislation of which was dictated by the current circumstances. Last but not least, I briefly refer to the reproduction right and its limitations in the field of related rights and to sum up I detail some concluding observations.

description: Η παρούσα έρευνα έχει ως στόχο να διερευνήσει τις γνώσεις και τις απόψεις των εκπαιδευτικών πρωτοβάθμιας εκπαίδευσης και τελειόφοιτων φοιτητών Δημοτικής Εκπαίδευσης, σχετικά με το νόημα και τα χαρακτηριστικά της δυσλεξίας. Επιπλέον, η έρευνα στοχεύει να διερευνήσει κατά πόσο αυτές οι απόψεις, επηρεάζονται από τις ασάφειες που επικρατούν στην οριοθέτησή της. Επιπλέον, διερευνάται αν οι απόψεις διαφοροποιούνται σε σημαντικό βαθμό ανάλογα με τύπο των ερωτώμενων (εκπαιδευτικοί-φοιτητές), την ηλικία και το φύλο. Το δείγμα της έρευνας αποτελούταν από 70 άτομα, εκ των οποίων τα 35 ήταν δάσκαλοι και 35 φοιτητές στο τελευταίο έτος των σπουδών τους, των οποίων, οι οποίοι απάντησαν σε ερωτηματολόγιο. Τα αποτελέσματα της έρευνας, έδειξαν ότι οι φοιτητές γνώριζαν περισσότερα για τα χαρακτηριστικά της δυσλεξίας και τη σημασία της αποκωδικοποίησης από ότι οι εκπαιδευτικοί, ενώ αντίθετα οι εκπαιδευτικοί φάνηκε ότι μπορούν να την ορίσουν, γνωρίζοντας για το φυσιολογικό της νοημοσύνης και της διαφοράς της από άλλες διαταραχές. Το εύρημα αυτό αποδεικνύει ότι υπάρχει σύγχυση για το ζήτημα της δυσλεξίας ανάμεσα σε αυτές τις δύο ομάδες, γιατί ενώ οι φοιτητές γνωρίζουν τα συμπτώματα της δυσλεξίας δε μπορούν να την ορίσουν, ενώ οι εκπαιδευτικοί μπορούν να την ορίσουν χωρίς να στην πράξη να μπορούν να την εντοπίσουν
description: The purpose of this study was to investigate the opinion and knowledge of primary school teachers and elementary school students about the meaning and characteristics of dyslexia. In addition, the research aims to investigate whether these views are influenced by the ambiguities in its meaning. Moreover, it is investigated whether opinions differ significantly depending on the type of respondents (students-teachers), age, and gender. The sample of the study consisted of 70 people, 35 of whom were teachers and 35 students in the last year of their studies, all of whom replied to a questionnaire. The results of the study revealed that students knew more about the characteristics of dyslexia and the importance of decoding than did the teachers, whereas teachers seemed to be able to define it, knowing about the intelligence of a dyslectic person and its difference from other disorders. This finding shows that there is confusion about the issue of dyslexia between these two groups, because while students know the symptoms of dyslexia they can't define it, whereas teachers can define it without actually being able to detect it

description: Programming by Example (PBE) is a program synthesis paradigm in which the synthesizer creates a program that matches a set of given examples. In many applications of such synthesis (e.g., program repair or reverse engineering), we are to reconstruct a program that is close to a specific target program, not merely to produce some program that satisfies the seen examples. In such settings, we wish that the synthesized program generalizes well, i.e., has as few errors as possible on the unobserved examples capturing the target function behavior. In this paper, we propose the first framework (called SynGuar) for PBE synthesizers that guarantees to achieve low generalization error with high probability. Our main contribution is a procedure to dynamically calculate how many additional examples suffice to theoretically guarantee generalization. We show how our techniques can be used in 2 well-known synthesis approaches: PROSE and STUN (synthesis through unification), for common string-manipulation program benchmarks. We find that often a few hundred examples suffice to provably bound generalization error below $5\%$ with high ($\geq 98\%$) probability on these benchmarks. Further, we confirm this empirically: SynGuar significantly improves the accuracy of existing synthesizers in generating the right target programs. But with fewer examples chosen arbitrarily, the same baseline synthesizers (without SynGuar) overfit and lose accuracy.

description: The formation of jets such as dynamic fibrils, mottles, and spicules in the solar chromosphere is one of the most important, but also most poorly understood, phenomena of the Sun's magnetized outer atmosphere. We use extremely high-resolution observations from the Swedish 1-m Solar Telescope combined with advanced numerical modeling to show that in active regions these jets are a natural consequence of upwardly propagating slow mode magnetoacoustic shocks. These shocks form when waves generated by convective flows and global p-mode oscillations in the lower lying photosphere leak upward into the magnetized chromosphere. We find excellent agreement between observed and simulated jet velocities, decelerations, lifetimes and lengths. Our findings suggest that previous observations of quiet sun spicules and mottles may also be interpreted in light of a shock driven mechanism.

description: Ως θέμα της ερευνητικής μελέτης ορίστηκε η φυτοχημική μελέτη των παραγώγων του φυτού Vitis Vinifera και η παραγωγή εκχυλισμάτων πλούσια σε ανθοκυάνες από στέμφυλα. Πιο συγκεκριμένα, για την παραγωγή εκχυλισμάτων με υψηλή περιεκτικότητα ανθοκυανών χρησιμοποιήθηκαν, ως φυτικό υλικό, στέμφυλα της ερυθρής ελληνικής ποικιλίας Ξινόμαυρο. Επιδιώχθηκε η αξιοποίηση των υποπροϊόντων οινοποίησης. με την ανάπτυξη μίας φιλικής προς το περιβάλλον διαδικασίας, κατά την οποία ανακτώνται οι φυσικές πολυφαινόλες υψηλής προστιθέμενης αξίας από αυτά. Για τον ίδιο σκοπό χρησιμοποιήθηκε το υπόλειμμα που προέκυψε από απόσταξη οίνου της ερυθρής ξενικής ποικιλίας Merlot. Τα δείγματα που προέκυψαν δόθηκαν για βιολογικές μελέτες. Παράλληλα, έγινε περαιτέρω επεξεργασία με σκοπό τη φυτοχημική του μελέτη και τη φαρμακολογική αξιολόγηση ορισμένων απομονωθέντων μεταβολιτών
description: The subject of the research study was the phytochemical study of Vitis Vinifera plant derivatives and the production of extracts rich in anthocyanins from rapeseed. In particular, for the production of extracts with high content of anthocyanins were used, as a plant material, the red Greek variety Xinomavro. The aim was to exploit the by-products of wine making by developing an environmentally friendly process in which natural polyphenols of high added value are recovered from them. For the same purpose, the residue resulting from the distillation of Merlot red wine was used. The resulting samples were given for biological studies. At the same time, further treatment was performed for the purpose of phytochemical study and pharmacological evaluation of some isolated metabolites

description: TV Ret was classified as a cataclysmic variable due to an outburst observed in 1977. We intended to confirm this classification and derive some basic properties of the system. Low resolution optical spectra were obtained for a spectral classification of the object. We find that the object is not a cataclysmic variable but an emission line galaxy with a redshift z=0.0964. An R-image taken in very good seeing conditions shows that the object is extended. We show that TV Ret is a blue dwarf galaxy, probably compact, with an absolute magnitude of MB = -17.5, a metallicity of 0.12 solar, and an average temperature of 1.3 10^4 K. The line ratios place it among the HII galaxies, although close to the border of the Seyfert2s. The outburst, which was observed in 1977, could thus be explained by a supernova explosion. However, with an absolute magnitude around MB = -21, it was an extremely bright one.

description: By using extensive tensor network calculations, we map out the phase diagram of the frustrated $J_1$-$J_2$ Ising model on the square lattice. In particular, we focus on the cases with controversy in the phase diagram, especially the stripe transition in the regime $g = |J_2/J_1|>\frac{1}{2}$, $(J_2>0,J_1<0)$. While recent studies claimed that the phase transition is of first order when $\frac{1}{2}

The motavation of male batterers and battered wives: a multi-case study using story sequence analysis
Creators: name: Kelly, Lillian Mary
Publisher: name: University of British Columbia
Year: 2009

description: This multi-case study explored the motivation patterns of 11 battered women and 3 male batterers. The Thematic Apperception Test (TAT) and Arnold’s story sequence analysis were utilized to obtain and analyze a series of 13 stories from each subject. Story imports were extrapolated from the subject’s story sequence to expose the motivating attitudes and were matched to a scoring criteria. The motivating attitudes form a pattern delineated in clinical evaluations. Then the imports and clinical evaluations of the battered women and male batterers were matched in a cross-case analysis of their respective groups. Finally, as a comparative validity measure, the cross-case analyses for each group were matched to the attitudes, values, and behaviors attributed to each group in the research literature. The battered wives, and the male batterers demonstrated negative motivation patterns. Therefore Arnold’s passive, pessimistic, self-centered, and malicious negative motivation pattern descriptions were used in the cross-case analyses. Negative passive and pessimistic patterns of motivation were common across both groups expressing a lack of contingency between actions and outcome, and pessimistic beliefs that one cannot overcome adversity by one’s own actions. These patterns matched learned helplessness that research has associated with battered wives, and depression, low self-esteem, and external locus of control attributed to male batterers. These results indicated that both battered women and male batterers have likely developed learned helplessness through their histories of family of origin violence. Additional results included patterns of motivation for the battered women matching the attributes of post-traumatic stress syndrome. The male batterers showed two patterns of motivation positive, passive, and pessimistic pattern and passive, pessimistic with self-centered and malicious motivation, which match the typical, and the narcissistic/anti-social types found for batterers in other research. This study, though exploratory in nature, contributes clarity to a vast and unwieldy theory on wife battering by revealing the underlying motivation of batterers and battered wives, and by exposing the correspondence of differing theoretical views to the same motivation patterns. Therefore the common motivation patterns found in this study provided a more clear analysis of the problems in living for battered women and male batterers. These motivation patterns can provide guidance regarding the dysfunction of these clients that can be utilized by clinicians in designing effective treatment for the problems of male batterers and of battered wives. Additionally the motivation patterns revealed through the TAT and story sequence analysis are effective and efficient means for accessing tacit self-knowledge that calls for further research.

description: Landauer's principle laid the main foundation for the development of modern thermodynamics of information. However, in its original inception the principle relies on semiformal arguments and dissipative dynamics. Hence, if and how Landauer's principle applies to unitary quantum computing is less than obvious. Here, we prove an inequality bounding the change of Shannon information encoded in the logical quantum states by quantifying the energetic cost of Hamiltonian gate operations. The utility of this bound is demonstrated by outlining how it can be applied to identify energetically optimal quantum gates in theory and experiment. The analysis is concluded by discussing the energetic cost of quantum error correcting codes with non-interacting qubits, such as Shor's code.
