description: The micropattern gaseous detector Micromegas has been developed for several years in Saclay and presents good performance for neutron detection. A prototype for neutron imaging has been designed and new results obtained in thermal neutron beams are presented. Based on previous results demonstrating a good 1D spatial resolution, a tomographic image of a multiwire cable has been performed using a 1D Micromegas prototype. The number of pillars supporting the micromesh is too large and leads to local losses of efficiency that distort the tomographic reconstruction. Nevertheless, this first tomographic image achieved with this kind of detector is very encouraging. The next worthwhile development for neutron imaging is to achieve a bi-dimensional detector, which is presented in the second part of this study. The purpose of measurements was to investigate various operational parameters to optimize the spatial resolution. Through these measurements the optimum spatial resolution has been found to be around 160 microns (standard deviation) using Micromegas operating in double amplification mode. Several 2D imaging tests have been carried out. Some of these results have revealed fabrication defects that occurred during the manufacture of Micromegas and that are limiting the full potential of the present neutron imaging system.

description: The central theme of the project is the negotiation of the triadic rules of Mitrophanes Smyrna. It is his most important work. They are called in the middle of the night every Sundays. His number is eight as well as the sounds of Byzantine music. This is a great hymnographic work with rich doctrinal content. Information is given about the ecclesial, political and spiritual environment of the time. Significant data are provided on the poetic type of the rule and on the features of the Methrofanis emphography. The structure, the language, the lyrical and the typographic patterns of the rules are discussed. The hymnographer in his hymns emphasizes the identity of the essence of the three persons of the Holy Trinity. speaks of the hypostatic idioms of the Father, the Son, and the Holy Spirit, and also considers the Virgin Maria as the deacon of the holly Scriptures

description: The main result of the paper is a version of the fundamental theorem of asset pricing (FTAP) for large financial markets based on an asymptotic concept of no market free lunch for monotone concave preferences. The proof uses methods from the theory of Orlicz spaces. Moreover, various notions of no asymptotic arbitrage are characterized in terms of no asymptotic market free lunch; the difference lies in the set of utilities. In particular, it is shown directly that no asymptotic market free lunch with respect to monotone concave utilities is equivalent to no asymptotic free lunch. In principle, the paper can be seen as the large financial market analogue of [Math. Finance 14 (2004) 351--357] and [Math. Finance 16 (2006) 583--588].

description: Additional file 11: Fig. S10. Illustration of the input, the assumptions and the output of the model. Measured cell counts and cell division dynamics are used to initialise the simulations. Organoid behaviour is based on the following main assumptions [1]. Each cell produces a substance with constant rate Jin, the substance leads to increase of internal pressure [2]. Cell displacement is driven by mechanical cell-cell-interactions, internal pressure and a surface energy of the organoid [3]. If the organoid shell ruptures, substance is released to the outside with flux Jout, releasing pressure and leading to a contraction of the sphere until the cell-cell connections are restored. The output of the model is the volume data as a function of time of the simulated organoids.

description: We present spatially resolved Hubble Space Telescope grism spectroscopy of 15 galaxies at $z\sim0.8$ drawn from the DEEP2 survey. We analyze H$α$+[N II], [S II] and [S III] emission on kpc scales to explore which mechanisms are powering emission lines at high redshifts, testing which processes may be responsible for the well-known offset of high redshift galaxies from the $z\sim0$ locus in the [O III]/H$β$ versus [N II]/H$α$ BPT (Baldwin-Phillips-Terlevich) excitation diagram. We study spatially resolved emission line maps to examine evidence for active galactic nuclei (AGN), shocks, diffuse ionized gas (DIG), or escaping ionizing radiation, all of which may contribute to the BPT offsets observed in our sample. We do not find significant evidence of AGN in our sample and quantify that, on average, AGN would need to contribute $\sim$25% of the H$α$ flux in the central resolution element in order to cause the observed BPT offsets. We find weak ($2σ$) evidence of DIG emission at low surface brightnesses, yielding an implied total DIG emission fraction of $\sim$20%, which is not significant enough to be the dominant emission line driver in our sample. In general we find that the observed emission is dominated by star forming H II regions. We discuss trends with demographic properties and the possible role of $α$-enhanced abundance patterns in the emission spectra of high redshift galaxies. Our results indicate that photo-ionization modeling with stellar population synthesis inputs is a valid tool to explore the specific star formation properties which may cause BPT offsets, to be explored in future work.

Exchange and correlation near the nucleus in density functional theory

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The near nucleus behavior of the exchange-correlation potential $v_{xc}({\bf r})$ in Hohenberg-Kohn-Sham density functional theory is investigated. It is shown that near the nucleus the linear term of $O(r)$ of the spherically averaged exchange-correlation potential ${\bar v}_{xc}(r)$ is nonzero, and that it arises purely from the difference between the kinetic energy density at the nucleus of the interacting system and the noninteracting Kohn-Sham system. An analytical expression for the linear term is derived. Similar results for the exchange $v_{x}({\bf r})$ and correlation $v_{c}({\bf r})$ potentials are also obtained separately. It is further pointed out that the linear term in $v_{xc}({\bf r})$ arising mainly from $v_{c}({\bf r})$ is rather small, and $v_{xc}({\bf r})$ therefore has a nearly quadratic structure near the nucleus. Implications of the results for the construction of the Kohn-Sham system are discussed with examples.

description: The aim of the present study was to determine changes in the dimensions of the peri-implant soft tissues, regarding the thickness of mucosa and the width of keratinized mucosa, at the time interval between the surgical placement of the implant/overlying CTG and implant exposure. In the Control Group the width of keratinized mucosa, the soft tissue thickness and the underlying bone (thickness and height) decreased at implant exposure. Similar effects were noted following CTG placement in the thick biotype. In the thin biotype, CTG failed to increase the zone of keratinized mucosa, but increased the mucosa thickness. Current findings imply that the surgical approach of a CTG in conjunction with two-stage implants increases the soft tissue thickness in thin biotypes, but may also impede bone healing and result in increased crestal bone resorptio

description: In the present thesis, systematic calculations of the ground state properties of even-even nuclei, are presented. The calculations were conducted within the relativistic Hartree-Bogoliubov theory in axial symmetry. The covariant density functional DD-ME2 was used for the calculations. It is considered one of the most successful functionals for the description of ground state, and excited state nuclei. In the present thesis, the systematic calculations with the functional DD-ME2, are presented, and cover a large portion of the period table, that includes nuclei in the range of 20 ≤ Ζ ≤ 98. The results for the properties of the ground state: binding energy, two neutron separation energy, quadropole deformation, were compared with the experimental data, and the comparison was considered as satisfying. The results, were also compared, with those from the non-relativistic macroscopic model, FRDM. This comparison was equivalently satisfying. This signifies the superiority of the microscopic models, over the macroscopic ones, because they derive from a more fundamental level of physics, and they contain far less parameters. In the particular case, the 10 parameters of the DD-ME2 functional, were fitted in the ground state properties of 12 spherical nuclei, while, the 47 parameters of FRDM, were fitted in over 1.300 experimental data.
description: Στην παρούσα διπλωματική εργασία παρουσιάζονται συστηματικοί υπολογισμοί ιδιοτήτων βασικής κατάστασης αρτίων-αρτίων πυρήνων. Οι υπολογισμοί πραγματοποιήθηκαν, στα πλαίσια της σχετικιστικής θεωρίας Hartree-Bogoliubov σε αξονική συμμετρία. Το συναλλοίωτο συναρτησοειδές πυκνότητας DD-ME2 χρησιμοποιήθηκε για τους υπολογισμούς. Αυτό θεωρείται από τα πιο επιτυχημένα συναρτησοειδή για περιγραφή βασικών και διεγερμένων καταστάσεων πυρήνων. Στην παρούσα εργασία, παρουσιάζονται για πρώτη φορά συστηματικοί υπολογισμοί με το συναρτησοειδές DD-ME2 για ένα μεγάλο μέρος του περιοδικού πίνακα, που περιλαμβάνει πυρήνες με άρτιο ατομικό αριθμό στην περιοχή από 20 ≤ Ζ ≤ 98. Τα αποτελέσματα για τις ιδιότητες βασικής κατάστασης: ενέργειας συνδέσεως, ενέργειας διαχωρισμού δύο νετρονίων, τετραπολική παραμόρφωση, συγκρίθηκαν με το πείραμα και η σύγκριση ήταν πολύ ικανοποιητική. Τα αποτελέσματα, συγκρίθηκαν επίσης, με αυτά που λαμβάνονται, από το μη-σχετικιστικό μακροσκοπικό πρότυπο FRDM. Η σύγκριση ήταν επίσης πολύ καλή. Αυτό σημαίνει την υπεροχή των μικροσκοπικών μοντέλων έναντι των μακροσκοπικών, διότι, ξεκινούν από ένα πιο θεμελιακό επίπεδο φυσικής, και περιλαμβάνουν πολύ λιγότερες παραμέτρους. Στην συγκεκριμένη περίπτωση, οι 10 παράμετροι του συναρτησοειδούς DD-ME2, προσαρμόστηκαν σε ιδιότητες βασικής κατάστασης, 12 σφαιρικών πυρήνων, ενώ, οι 47 παράμετροι του FRDM, προσαρμόστηκαν, σε πάνω από 1300 πειραματικά δεδομένα.
Out of context: identity rupture and repair in self-exiled white South Africans
Creators: name: Feuchtwanger, Lawrence D. A.
Publisher: name: University of British Columbia
Year: 2009

description: Cultural dislocation potentially poses a number of threats to the dislocated individual’s previously established sense of self. For the self-exile (who is nominally free to remain in her or his country of origin but chooses--both for reasons of conscience and a desire to escape--to leave) this occurs, in large part, because of context interruption (Barudy, 1989), the loss of the socio-cultural milieu in which the self-exile’s identity was created and maintained. A qualitative, phenomenological approach (using a case study method) was utilized to explore the experience and meaning of self-exile for white, English-speaking South Africans living in Canada and to examine the impact of cultural dislocation on the selfexiled person’s sense of self (identity). Identity was defined as self-narrative, jointly created by the individual and the culture in which he or she lives. Three co-researchers (two women and one man) who were self-exiled from South Africa participated in this study. During individual in-depth interviews which were audiotaped, the co-researchers described their experience of self-exile from the time that they had made the decision to leave South Africa up until a point where they felt they had come to terms with living in Canada. A comparative analysis was conducted to uncover structural and thematic commonalities. The self-exile experience was seen to be structured as a story with a beginning, middle, and end, which structure resembled a rite of passage, with three sequential but overlapping phases: separation, transition, and incorporation (van Gennep, 1965). The beginning and middle (separation and transition) were marked by themes of exclusion and personal deficiency, the transition by a denial of (cultural) identity, while the end (incorporation) involved a reversal of these themes, narrative resolution being achieved through a sense of inclusion, increased self-worth and identity acceptance.

description: Cook's [J. Roy. Statist. Soc. Ser. B 48 (1986) 133--169] local influence approach based on normal curvature is an important diagnostic tool for assessing local influence of minor perturbations to a statistical model. However, no rigorous approach has been developed to address two fundamental issues: the selection of an appropriate perturbation and the development of influence measures for objective functions at a point with a nonzero first derivative. The aim of this paper is to develop a differential--geometrical framework of a perturbation model (called the perturbation manifold) and utilize associated metric tensor and affine curvatures to resolve these issues. We will show that the metric tensor of the perturbation manifold provides important information about selecting an appropriate perturbation of a model. Moreover, we will introduce new influence measures that are applicable to objective functions at any point. Examples including linear regression models and linear mixed models are examined to demonstrate the effectiveness of using new influence measures for the identification of influential observations.

description: In recent papers Mannucci et al. (2005, 2006) suggested, on the basis of observational arguments, that there is a bimodal distribution of delay times for the explosion of Type Ia SNe. In this paper, we test this hypothesis in models of chemical evolution of galaxies of different morphological type: ellipticals, spirals and irregulars. We show that this proposed scenario is compatible also with the main chemical properties of galaxies. When the new rate is introduced in the two-infall model for the Milky Way, the derived Type Ia SN rate as a function of cosmic time shows a high and broad peak at very early epochs thus influencing the chemical evolution of the galactic halo more than in the previous widely adopted formulations for the SNIa rate. As a consequence of this, the [O/Fe] ratio decreases faster for [Fe/H] > -2.0 dex, relative to the old models. For a typical elliptical of 10^11 M_sun of luminous mass, the new rate produces average [alpha/ Fe] ratios in the dominant stellar population still in agreement with observations. The Type Ia SN rate also in this case shows an earlier peak and a subsequent faster decline relative to the previous results, but the differences are smaller than in the case of our Galaxy. We have also checked the effects of the new Type Ia SN rate on the evolution of the Fe content in the ICM, as a consequence of its production from cluster ellipticals and we found that less Fe in the ICM is produced with the new rate, due to the higher fraction of Fe synthesized at early times and remaining locked into the stars in ellipticals. For dwarf irregular galaxies suffering few bursts of star formation we obtain [O/Fe] ratios larger by 0.2 dex relative to the previous models.

description: Atom-interferometer gravitational-wave (GW) observatory, as a new design of ground-based GW detector for the near future, is sensitive at a relatively low frequency for GW observations. Taking the proposed atom interferometer Zhaoshan Long-baseline Atom Interferometer Gravitation Antenna (ZAIGA), and its illustrative upgrade (Z+) as examples, we investigate how the atom interferometer will complement ground-based laser interferometers in testing the gravitational dipole radiation from binary neutron star (BNS) mergers. A test of such kind is important for a better understanding of the strong equivalence principle laying at the heart of Einstein's general relativity. To obtain a statistically sound result, we sample BNS systems according to their merger rate and population, from which we study the expected bounds on the parameterized dipole radiation parameter $B$. Extracting BNS parameters and the dipole radiation from the combination of ground-based laser interferometers and the atom-interferometer ZAIGA/Z+, we are entitled to obtain tighter bounds on $B$ by a few times to a few orders of magnitude, compared to ground-based laser interferometers alone, ultimately reaching the levels of $|B| \lesssim 10^{-9}$ (with ZAIGA) and $|B| \lesssim 10^{-10}$ (with Z+).

description: The aim of this thesis is to saw the need of distinction between productive and non-productive labor in political economy. For this reason, apart from the historical reflection of the subject and the effects that this has on each of the economic schools of thought, while making a separate reference to the National Accounts System, an empirical investigation is also necessary. By classifying government spending into productive and non-productive, the relationship between GDP and government spending is explored using data for 14 countries of the European Union grouped in North and South countries for the period 2000-2014. In the literature, this relationship is called Wagner's law and the findings of empirical studies are contradictory, depending mainly on the type of variables used and on whether countries are considered developed or developing. Using modern econometric methods of cointegration, the results of this research show a bi-directional relationship between GDP and productive expenditures and a causal relationship from non-productive expenditure to GDP.

description: Loop models have been widely studied in physics and mathematics, in problems ranging from polymers to topological quantum computation to Schramm-Loewner evolution. I present new loop models which have critical points described by conformal field theories. Examples include both fully-packed and dilute loop models with critical points described by the superconformal minimal models and the SU(2)_2 WZW models. The dilute loop models are generalized to include SU(2)_k models as well.

description: Although of practical importance, there is no established modeling framework to accurately predict high-temperature cyclic oxidation kinetics of multi-component alloys due to the inherent complexity. We present a data analytics approach to predict the oxidation rate constant of NiCr-based alloys as a function of composition and temperature with a highly consistent and well-curated experimental dataset. Two characteristic oxidation models, i.e., a simple parabolic law and a statistical cyclic-oxidation model, have been chosen to numerically represent the high-temperature oxidation kinetics of commercial and model NiCr-based alloys. We have successfully trained machine learning (ML) models using highly ranked key input features identified by correlation analysis to accurately predict experimental parabolic rate constants (kp). This study demonstrates the potential of ML approaches to predict oxidation kinetics of alloys over a wide composition and temperature ranges. This approach can also serve as a basis for introducing more physically meaningful ML input features to predict the comprehensive cyclic oxidation behavior of multi-component high-temperature alloys with proper constraints based on the known underlying mechanisms.

description: We present high spatial resolution observations of the mid-infrared core of the dusty symbiotic system HM Sge. The MIDI interferometer was used with the VLT UTs and ATs providing baselines oriented from PA=42° to 105°. The MIDI visibilities are compared with the ones predicted in the frame of various spherical dust shells published in the literature involving single or double dusty shells. The mid-IR environment is unresolved by a 8m telescope and the MIDI spectrum exhibits a level similar to the ISO spectra recorded 10 yr ago. The estimated Gaussian HWHM of the shell of 12AU in the 8-9$μ$m range, and 18AU in the 11-12$μ$m range, are much smaller than the angular separation between the Mira and the White Dwarf of 60AU. The discrepancies between the HWHM at different angle orientations suggest an increasing level of asymmetry from 13 to 8$μ$m. The observations are well fitted by the densest and smallest model published in the literature based on the ISO data, although such a model does not account for the variations of near-IR photometry due to the Mira pulsation cycle suggesting a much smaller optical thickness. These observations also discard the two shells models, developed to take into account the effect of the WD illumination onto the dusty wind of the Mira. These observations show that a high rate of dust formation is occurring in the vicinity of the Mira which seems to be not highly perturbed by the hot companion.

description: The properties of the least-bound vibrational level (v=14) of the quintet sigma state formed during the ultracold collision of two spin-polarized metastable helium atoms are crucial to studies of photoassociation spectroscopy of metastable helium. We report a calculation of the autoionization lifetime of this state induced by spin-dipole coupling of the quintet sigma state to the singlet sigma state from which Penning and associative ionization processes are highly probable. We find a lifetime of about 150 microseconds, significantly larger than the recent experimental estimates of (4-5) microseconds.

description: Η παρούσα διπλωματική εργασία μελετά την ευστάθεια των αναλυτικών λύσεων Tolman-Oppenheimer-Volkoff . Συγκεκριμένα, μελετάμε την ευστάθεια τριών αναλυτικών λύσεων των εξισώσεων πεδίου του Einstein. Οι λύσεις αυτές είναι κατάλληλες για να περιγράψουμε συμπαγή αντικείμενα όπως λευκούς νάνους, αστέρες νετρονίων και υπερμεγέθη αστέρες. Στην περίπτωση μας μελετήσαμε την ευστάθεια της λύσης Tolmann VII ,την λύση Buchdahl και τέλος την λύση Nariai IV. Από την μελέτη των παραπάνω αναλυτικών λύσεων καταλήξαμε στο γεγονός ότι σε ένα εκτεταμένο εύρος της παραμέτρου β οι λύσεις είναι ευσταθείς. Ακόμα μελετήσαμε την εξάρτηση του αδιαβατικού δείκτη γ στο κριτήριο της ευστάθειας. Συγκεκριμένα, συγκρίναμε τον μέσο αδιαβατικό δείκτη με την κρίσιμη τιμή του αδιαβατικού δείκτη γcr και συμπεράναμε ότι υπάρχει μια συγκεκριμένη σχέση για την περιοχή ευστάθειας των σχετικιστικών αστέρων
description: This diploma thesis studies the stability of analytical solutions Tolman-Oppenheimer-Volkoff. In particular, we study the stability of three analytical solutions of the Einstein's field equations. These solutions are suitable to describe compact objects such as white dwarfs, neutron stars and supermassive stars. In our thesis we studied the stability of three solutions, the Tolman VII solution, the Buchdahl solution and the Nariai IV solution. From the study of the above analytical solutions we concluded that in an extended range of parameter β the solutions are stable. We have also studied the dependence of the adiabatic index γ on the stability criterion. In particular, we compared the average adiabatic index to the critical value of the adiabatic index γcr and concluded that there is a specific relationship for the stability region of the relativistic star
Laser Absorption Measurements of Electron Density in Nanosecond-ScaleAtmospheric Pressure Pulsed Plasmas

description: We report on time-resolved measurements of electron number density by continuous-wave laser absorption in a low-energy nanosecond-scale laser-produced spark in atmospheric pressure air. Laser absorption is a result of free-free and bound-free electron excitation, with the absorption coefficient modeled and evaluated using estimates of the time-variation in electron temperature and probe laser absorption path length. Plasma electron number densities are determined to be as high as $n_\text{e}=7\times10^{19}$ cm$^{-3}$, and decay to $1/e$ of their peak values over a period of about 50 ns following plasma formation using a 20 mJ, 10 ns pulse width frequency-doubled Nd:YAG laser. The measured plasma densities at later times are shown to be in reasonable agreement with Stark broadening measurements of the 3s[$^5S{^o}$]-3p[$^5P$] electronic transition in atomic oxygen at 777 nm. This study provides support for the use of such continuous wave laser absorption for time resolved electron density measurements in low energy spark discharges in air, provided that an estimate of the electron temperature and laser path length can be made by accompanying diagnostics.

description: Additional file 12: Fig. S11. Analysis of simulated monocystic mPOs. Simulations starting with heterogenous initial cell numbers confirm an influence of organoid size onto the number of oscillation events. The colour code signals the number of registered size oscillation events. The amount of size oscillations is dependent on the initial size of the organoids. While small organoids tend to show frequent inflation-deflation oscillations, initially larger organoids seem less prone to oscillation events.
Analytic theory of pair distribution functions in symmetric electron-electron and electron-hole bilayers

description: We present a self-consistent analytic theory of the intra-layer and inter-layer pair correlation functions in electron-electron and electron-hole fluid bilayer systems. Our approach involves the solution of a zero-energy scattering Schroedinger equation with an effective potential which includes a Bose-like term from Jastrow-Feenberg correlations and a Fermi term from kinetic energy and exchange, tailored to yield the Hartree-Fock limit at high carrier density. The theory is also shown to satisfy the plasmon sum rule and the charge neutrality condition. We obtain good agreement with the available Quantum Diffusion Monte Carlo (DMC) data in symmetric bilayers over a wide range of carrier density and layer spacing, and stress the role of three-body correlation terms in yielding fully quantitative agreement at strong coupling. Signals of impending transitions to density-modulated states at strong coupling and low layer spacing appear in the calculated pair correlations through inter-layer in-phase oscillations for electron-hole bilayers and out-of-phase oscillations for electron-electron bilayers, in agreement with the DMC findings.
