description: Fitting whole spectra at intermediate spectral resolution (R = 1000 -- 3000), to derive physical properties of stellar populations, appears as an optimized alternative to methods based on spectrophotometric indices: it uses all the redundant information contained in the signal. This paper addresses the validation of the method and it investigates the quality of the population models together with the reliability of the fitting procedures. We are using two algorithms: STECKMAP, a non-parametric regularized program and NBURSTS a parametric non-linear minimization. We compare three spectral synthesis models for single stellar populations: Pegase-HR, Galaxev (BC03) and Vazdekis/Miles, and we analyse spectra of Galactic clusters whose populations are known from studies of color-magnitude diagrams (CMD) and spectroscopy of individual stars. We find that: (1) The quality of the models critically depends on the stellar library they use. Pegase-HR and Vazdekis/Miles are consistent, while the comparison between Pegase-HR and BC03 shows some systematics reflecting the limitations of the stellar library (STELIB) used to generate the latter models; (2) The two fitting programs are consistent; (3) For globular clusters and M67 spectra, the method restitutes metallicities in agreement with spectroscopy of stars within 0.14 dex; (4) The spectroscopic ages are very sensitive to the presence of a blue horizontal branch (BHB) or of blue stragglers. A BHB morphology results in a young SSP-equivalent age. Fitting a free amount of blue stars in addition to the SSP model to mimic the BHB improves and stabilizes the fit and restores ages in agreement with CMDs studies. This method is potentially able to disentangle age or BHB effects in extragalactic clusters.

description: We propose a new unified model that describes~dark energy and dark matter in the context of $f(R,ϕ)$ gravity using a massive scalar field in five dimensions. The scalar field is considered in the bulk that surrounds the 3-brane in branworld model. We show that for a specific choice of the $% f(R,ϕ)$ function, we can describe the Einstein gravitation in 4-dimensional space-time. We obtain a relationship between the speed of the universe's expansion and the speed of the bulk's expansion. We also propose that the dark matter is represented by the scalar field mass and that the dark energy is a kinetic energy of this field. Finally, we show that, according to conditions, one can obtain the percentages of density\ of dark matter and the density of ordinary matter.

description: The present study tries to highlight the form of reformation of manufacturing activity that is followed in each region of Greece and to pinpoint, if they exist, the regional differentiations of mentioned before form. This particular research concerns in period 1993-2006 and the industrial shops that participate in the research are those that occupy more than 20 employees, supported substantially in the exploitation of data that collects the GREEK NATIONAL STATISTICAL ORGANISATION with the Annual Industrial Research (EVE), (which constitutes an inventory process of industrial shops with more than 20 employees). The emergence of form of regional reformation of Greek transformation is based on the calculation of a series of sizes and indicators, which we study their development during the period 1993-2006 and more specifically we focus on four of them that detect whether the main aiming of reformation is related with acceleration or deceleration of investments and the involving changes in the quantity and quality of employment.

description: Quantum decoherence, the evolution of pure states into mixed states, may be a feature of quantum-gravity models. In most cases, such models lead to fewer neutrinos of all active flavours being detected in a long baseline experiment as compared to three-flavour standard neutrino oscillations. We discuss the potential of the CNGS and J-PARC beams in constraining models of quantum-gravity induced decoherence using neutrino oscillations as a probe. We use as much as possible model-independent parameterizations, even though they are motivated by specific microscopic models, for fits to the expected experimental data which yield bounds on quantum-gravity decoherence parameters.

Optical reflectivity as a simple diagnostic method for testing structural quality of icosahedral quasicrystals

description: Optical reflectivity as a simple diagnostic method for testing structural quality of icosahedral quasicrystals 2 The optical reflectivity of Al-based and Ti-based quasicrystalline and approximant samples were investigated versus the quality of their structural morphology using optical reflectometry, X-ray diffraction and transmission electron microscopy. The different structural morphologies were obtained using three different preparation processes : sintering, pulsed laser deposition and reactive cathodic magnetron sputtering. The work demonstrates that the canonical behaviour of icosahedral state in specular reflectivity is extremely sensitive to different and very fine aspects of the microstructure : sizes of grains smaller than 50 nm, slight local diffuse disorder and shifts away from the icosahedral crystallographic structure (approximants). The work explains why the optical properties of the same kind of quasicrystals found in literature sometimes reveal a different behaviour from one author to another. The study then confirms the work of some authors and definitely shows that the canonical behaviour of icosahedral state in specular reflectivity over the 30000-50000 cm-1 domain is characterized by a decreasing function made of steps. It also shows that this behaviour can be interpreted thanks to the cluster hierarchy of the model of Janot.

description: For any lattice polytope $P$, we consider an associated polynomial $\barδ_{P}(t)$ and describe its decomposition into a sum of two polynomials satisfying certain symmetry conditions. As a consequence, we improve upon known inequalities satisfied by the coefficients of the Ehrhart $δ$-vector of a lattice polytope. We also provide combinatorial proofs of two results of Stanley that were previously established using techniques from commutative algebra. Finally, we give a necessary numerical criterion for the existence of a regular unimodular lattice triangulation of the boundary of a lattice polytope.

description: We present the results of a search for the production of an excited state of the electron, e*, in proton-antiproton collisions at sqrt(s) = 1.96 TeV. The data were collected with the D0 experiment at the Fermilab Tevatron Collider and correspond to an integrated luminosity of approximately 1 fb^-1. We search for e* in the process ppbar -> e* e, with the e* subsequently decaying to an electron plus photon. No excess above the standard model background is observed. Interpreting our data in the context of a model that describes e* production by four-fermion contact interactions and e* decay via electroweak processes, we set 95% C.L. upper limits on the production cross section ranging from 8.9 fb to 27 fb, depending on the mass of the excited electron. Choosing the scale for contact interactions to be Lambda = 1 TeV, excited electron masses below 756 GeV are excluded at the 95% C.L.

Our results are based on the 7-D measurements supplied by $Gaia$ and the chemical composition derived from a high-resolution ($R\sim 110,000$), high signal-to-noise ratio ($S/N \sim 60)$ optical spectrum obtained by the 2.4\,m Automated Planet Finder Telescope at Lick Observatory. We obtain chemical abundances of 31 elements (from lithium to thorium).

description: We analyze the zero-temperature phases of an array of neutral atoms on the kagome lattice, interacting via laser excitation to atomic Rydberg states. Density-matrix renormalization group calculations reveal the presence of a wide variety of complex solid phases with broken lattice symmetries. In addition, we identify a novel regime with dense Rydberg excitations that has a large entanglement entropy and no local order parameter associated with lattice symmetries. From a mapping to the triangular lattice quantum dimer model, and theories of quantum phase transitions out of the proximate solid phases, we argue that this regime could contain one or more phases with topological order. Our results provide the foundation for theoretical and experimental explorations of crystalline and liquid states using programmable quantum simulators based on Rydberg atom arrays.

description: We present medium resolution spectropolarimetry and long term photo-polarimetry of two massive post-red supergiants, IRC +10420 and HD 179821. The data provide new information on their circumstellar material as well as their evolution. In IRC +10420, the polarization of the Halpha line is different to that of the continuum, which indicates that the electron-scattering region is not spherically symmetric. The observed long term changes in the polarimetry can be associated with an axi-symmetric structure, along the short axis of the extended reflection nebulosity. Long term photometry reveals that the star increased in temperature until the mid-nineties, after which the photospheric flux in the optical levelled off. As the photometric changes are mostly probed in the red, they do not trace high stellar temperatures sensitively. And so, it is not obvious whether the star has halted its increase in temperature or not. For HD 179821 we find no polarization effects across any absorption or emission lines, but observe very large polarization changes of order 5% over 15 years. Unexpectedly, during the same period, the optical photometry displayed modest variability at the 0.2 magnitude level. Several explanations for this puzzling fact are discussed. Most of which, involving asymmetries in the circumstellar material, seem to fail as there is no evidence for the presence of hot, dusty material close to the star. Alternatively, the variations can be explained by the presence of a non-radially pulsating photosphere. Changes in the photometry hint at an increase in temperature corresponding to a change through two spectral subclasses over the past ten years.

description: Difference-phase (or Hanbury Brown - Twiss type) intensity interference of classical light is considered in higher orders in the intensity. It is shown that, while the visibility of sum-phase (NOON-type) interference for classical sources drops with the order of interference, the visibility of difference-phase interference has opposite behavior. For three-photon and four-photon interference of two coherent sources, the visibility can be as high as 81.8% and 94.4%, respectively. High-visibility three-photon and four-photon interference of space-time and polarization types has been observed in experiment, for both coherent and pseudo-thermal light.

Fragmentation of Collapsar Disks and the Production of Gravitational Waves

description: We argue that gravitational instability in the outer parts of collapsar disks may lead to fragmentation near the radius where helium photodisintegrates, because of the strong cooling provided by this process. This physics sets clear physical scales for the fragmentation conditions and the properties of gravitationally bound clumps. Collapse of a fragment proceeds until the neutrons become degenerate; a neutron star of mass ~0.1-1Msun may result. We find that tidal disruption of a fragment and accretion by the central black hole are too rapid to account for the durations of observed X-ray flares from long gamma-ray bursts. Prior to disruption, migration of the fragment is driven by gravitational radiation and disk viscosity, which act together to produce a unique gravitational-wave signature. Advanced LIGO may be able to detect such sources within ~100 Mpc.

Do quasi-regular structures really exist in the solar photosphere? I. Observational evidence
Creators: name: Getling, A. V.
Publisher: name: arXiv
Year: 2006

description: Two series of solar-granulation images -- the La Palma series of 5 June 1993 and the SOHO MDI series of 17--18 January 1997 -- are analysed both qualitatively and quantitatively. New evidence is presented for the existence of long-lived, quasi-regular structures (first reported by Getling and Brandt (2002)), which no longer appear unusual in images averaged over 1--2-h time intervals. Such structures appear as families of light and dark concentric rings or families of light and dark parallel strips (``ridges'' and ``trenches'' in the brightness distributions). In some cases, rings are combined with radial ``spokes'' and can thus form ``web'' patterns. The characteristic width of a ridge or trench is somewhat larger than the typical size of granules. Running-average movies constructed from the series of images are used to seek such structures. An algorithm is developed to obtain, for automatically selected centres, the radial distributions of the azimuthally averaged intensity, which highlight the concentric-ring patterns. We also present a time-averaged granulation image processed with a software package intended for the detection of geological structures in aerospace images. A technique of running-average-based correlations between the brightness variations at various points of the granular field is developed and indications are found for a dynamical link between the emergence and sinking of hot and cool parcels of the solar plasma. In particular, such a correlation analysis confirms our suggestion that granules -- overheated blobs -- may repeatedly emerge on the solar surface. Based on our study, the critical remarks by Rast (2002) on the original paper by Getling and Brandt (2002) can be dismissed.

description: Τα τελευταία χρόνια έχουν αναπτυχθεί μέθοδοι επιλογής δείγματος για έρευνες που γίνονται μέσω τηλεφωνικών συνεντεύξεων σε νοικοκυριά, με κλήση τηλεφωνικού αριθμού με τυχαία ψηφία (με χρήση συγκεκριμένων προθεμάτων). Οι μέθοδοι αυτοί μειώνουν σημαντικά το κόστος τέτοιων ερευνών σε σχέση με της έρευνες που γίνονται με κλήση αριθμών εντελώς στην τύχη και σ' αυτές που γίνονται πόρτα-πόρτα και είναι πιο αποδοτικοί από τις έρευνες που γίνονται μέσω καταλόγων. Η απλή τυχαία δειγματοληψία, τηλεφωνικών αριθμών ανάμεσα στις υπάρχουσες τηλεφωνικές συνδέσεις, είναι ανεπαρκής, επειδή μόνο το 20% περίπου αυτών των αριθμών είναι στην πραγματικότητα οικιακοί αριθμοί. Η έρευνα μέσω καταλόγων δεν μπορεί να είναι αντιπροσωπευτική αφού κάποιοι δεν είναι γραμμένοι στους καταλόγους. Τέλος, η μέθοδος πόρτα-πόρτα είναι ακριβή και όχι πάντα επιτυχής στην εξαγωγή απαντήσεων καθώς ορισμένες φορές οι κάτοικοι διστάζουν να ανοίξουν την πόρτα τους και να απαντήσουν. Η μέθοδος επιλογής που προτείνεται (κλήση τηλεφωνικού αριθμού με τυχαία ψηφία) μειώνει σημαντικά το κόστος και το ποσοστό των μη χρήσιμων αριθμών.
description: In recent years, there has been a development in methods of sample selection, for surveys carried out through telephone interviews in households, with the use of random digit dialing (using specific prefixes). These methods significantly reduce the cost of such surveys, when compared to surveys conducted by dialing numbers completely at random and those carried out using door-to-door interview, and are more efficient than surveys that make use of telephone directories.Simple random sampling of telephone numbers from the existing telephone connections is inadequate, because only 20% of these numbers are, in fact, residential. The use of telephone directories does not always lead to accurate results, because some households are not listed in them.Door-to-door research is expensive and not always successful in getting answers, as certain individuals hesitate to open their doors and answer. The proposed method of selection (random digit dialing) significantly reduces the cost as well as the percentage of non-working numbers.
Call-by-value Termination in the Untyped lambda-calculus

description: A fully-automated algorithm is developed able to show that evaluation of a given untyped lambda-expression will terminate under CBV (call-by-value). The ``size-change principle'' from first-order programs is extended to arbitrary untyped lambda-expressions in two steps. The first step suffices to show CBV termination of a single, stand-alone lambda;-expression. The second suffices to show CBV termination of any member of a regular set of lambda-expressions, defined by a tree grammar. (A simple example is a minimum function, when applied to arbitrary Church numerals.) The algorithm is sound and proven so in this paper. The Halting Problem's undecidability implies that any sound algorithm is necessarily incomplete: some lambda-expressions may in fact terminate under CBV evaluation, but not be recognised as terminating. The intensional power of the termination algorithm is reasonably high. It certifies as terminating many interesting and useful general recursive algorithms including programs with mutual recursion and parameter exchanges, and Colson's ``minimum'' algorithm. Further, our type-free approach allows use of the Y combinator, and so can identify as terminating a substantial subset of PCF.

description: We present results from a near-infrared (NIR) adaptive optics (AO) survey of pre-main-sequence stars in the Lupus Molecular Cloud with VLT/NACO to identify (sub)stellar companions down to $\sim$20 au separation and investigate the effects of multiplicity on circumstellar disc properties. We observe for the first time in the NIR with AO a total of 47 targets and complement our observations with archival data for another 58 objects previously observed with the same instrument. All 105 targets have millimetre ALMA data available, which provide constraints on disc masses and sizes. We identify a total of 13 multiple systems, including 11 doubles and 2 triples. In agreement with previous studies, we find that the most massive (M$_{\rm dust}$ $>$ 50 M$_{\oplus}$) and largest ($R_{\rm dust}>$ 70 au) discs are only seen around stars lacking visual companions (with separations of 20-4800 au) and that primaries tend to host more massive discs than secondaries. However, as recently shown in a very similar study of $>$200 PMS stars in the Ophiuchus Molecular Cloud, the distribution of disc masses and sizes are similar for single and multiple systems for M$_{\rm dust} < 50$ M$_{\oplus}$ and radii $R_{\rm dust}$20 au mostly affect discs in the upper 10$\%$ of the disc mass and size distributions.

Effect of coagulation and flocculation technology on bleached kraft mill effluent quality
Creators: name: Hodgson, Andrew Trevor
Publisher: name: University of British Columbia
Year: 2009

description: Since January 1995 the tertiary colour removal clarifier at Crestbrook Forest Industries' Pulp Division in Skookumchuck, B.C. has removed 60±4% of the biologically treated effluent colour. Over the same period, BOD5 was reduced by 26% and TSS was increased by 19 mg/L across tertiary treatment. This study revealed that the colour removal system removed 24%, 23%, 80%, and 18% of the COD, AOX, 2,3,7,8-TCDF, and mixed function oxygenase induction, respectively. A study of the effect that basic effluent parameters had on system performance revealed that the dual polymer system used at Crestbrook Forest Industries operated well over a wide range of temperature, pH, and BOD₅. Colour removal improved when pH was decreased to pH 3; below this pH the system performance declined. The increased colour removal at lower pH values could not be achieved by an increase in coagulant dose. Decreasing the temperature improved colour removal slightly, and different levels of BOD5 had no effect on the percentage of colour removed. Bench scale tests with segregated effluent streams (bleach plant filtrates and pulping area sewers), indicated that there are no possible reductions in polymer usage when these streams are treated separately from the rest of the mill effluent. Polymers used in the full scale system were well suited to treat chlorination stage effluent, achieving acceptable floe formation at relatively low polymer applications. The extraction stage effluent did not produce quality floes when treated, and required high polymer doses to achieve moderate floe quality.

description: The Bishop of Kydonia and Apokorona Agathaggelos Ninolakis (1912-1935) is one of the most influential persons in Crete, who played a dynamic and important role in matters of the church during the last decade of the 19th century and the first four decades of the 20th century. This cleric of Kydonia lived in a time of great political upheaval and difficult military conflict, that brought rapid changes not only in the global geopolitical map, but also in the way people thought. At a young age, Aggathaggelos showed remarkable ecclesiastical action, which escalated and expanded when he entered into the the clergy, and reached a pinnacle when he took on the leadership role of Bishop of Chania. The person and actions of Bishop Agathaggelos Ninolakis is the subject of this graduate thesis, which is intended to show his contribution to the church of Crete, but also to Crete itself, a contribution that is not limited to the time in which he lived, but that extends into the present, a time in which the church is called upon to address the problems and challenges of the 3rd millennium.

description: Pulsed laser deposition from a Nd:YAG laser was employed in production of hundreds of nanometer thick quasicrystalline Ti-Zr-Ni films on glass substrate. The influence of deposition temperature Ts on the structure, morphology and microstructure of the films across their thickness was investigated. The morphology and microstructure features were evaluated by X-ray diffraction and transmission electron microscopy techniques. The low deposition temperatures were found to produce films with nanometer sized grains embedded in an amorphous matrix. The grains exhibit quasicrystalline order. The higher deposition temperatures lead to films whose structure is not uniform all along the growth direction. The layer in contact with the substrate is a very thin amorphous layer. The main part of the film consists of crystallized columns. The columns have grown from a nano-crystallized layer where the size of crystallites increases with increasing thickness.
