description: It is widely accepted that the Universe underwent a period of thermal equilibrium at very early times. One expects a residue of this primordial state to be imprinted on the large scale structure of space time. In this paper we study the morphology of this thermal residue in a universe whose early dynamics is governed by a scalar field. We calculate the amplitude of fluctuations on large scales and compare it to the imprint of vacuum fluctuations. We then use the observed power spectrum of fluctuations on the cosmic microwave background to place a constraint on the temperature of the Universe before and during inflation. We also present an alternative scenario where the fluctuations are predominantly thermal and near scale-invariant.

description: Η αξιολόγηση των χρηματοοικονομικών επιδόσεων και της ευρωστίας είναι κρίσιμη για κάθε εταιρεία. Αυτό δίνει τη γενική κατεύθυνση μιας επιχείρησης για την αξιολόγηση των δυνατοτήτων και των αδυναμιών της σε σύγκριση με άλλες ομοειδείς επιχειρήσεις του κλάδου. Οι πληροφορίες που λαμβάνονται από την ανάλυση των χρηματοοικονομικών δεικτών είναι σημαντικές όχι μόνο για τον διευθυντή μιας επιχείρησης, αλλά και για τα ενδιαφερόμενα μέρη για τη λήψη τεκμηριωμένων αποφάσεων. Η παρούσα μελέτη είναι μια αξιολόγηση της εταιρείας GENERAL MILLS INC. με την υιοθέτηση της ανάλυσης χρηματοοικονομικών δεικτών, του μέσου σταθμικού κόστους (WACC) και της προεξόφλησης των ταμειακών ροών (DCF). Επίσης γίνεται και σύντομη αναφορά και ανάλυση αριθμοδεικτών της ανταγωνίστριας επιχειρήσης NESTLE. Τα δεδομένα προέρχονται από τις οικονομικές καταστάσεις της εταιρείας κατά τη διάρκεια 4 ετών. Η μελέτη έδειξε ότι η GENERAL MILLS INC. κατέχει ισχυρή θέση όσον αφορά την αποδοτικότητα και την κερδοφορία της, την οποία απολαμβάνει τα τελευταία τέσσερα χρόνια, μέσω της αποτελεσματικότητας της διοίκησής της και της καλής φήμης της στον κλάδο τροφίμων και ποτών. Επίσης η τιμή του WACC καθώς και ο ρυθμός ανάπτυξης της επιχειρήσης είναι ευνοϊκά.

description: Genus Stylatula Verrill, 1864
GENERIC DIAGNOSIS.— Virgulariid pennatulaceans with slender, bilateral, often vermiform colony shape. Axis present throughout colony length, most often round in transverse section. Polyp leaves subtended by fanlike armatures of spindle-like to needle-like sclerites, which may or may not be three-flanged. Sclerites from other parts of colony inconspicuous to absent.
TYPE SPECIES.— Virgularia elongata (Gabb, 1862); subsequent designation by Verrill, 1864; type locality California.
ETYMOLOGY.— The generic name is derived from the Greek Stylos: a style, stake, or pillar.
SYSTEMATICS AND PHYLOGENETIC ASSESSMENT.— The genus Stylatula contains thirteen described species from the Atlantic and Pacific Oceans (Japan to Norway), between approximately 65° north and 50° south latitude (Fig. 9). With the addition of the new species described here, thirteen species are considered valid; known geographic range Atlantic and Pacific Oceans (Japan to North & South America to Norway and Namibia), 0–1020 m in depth (Williams 1995:122; Williams 2011:6; Williams 2014). The genus Stylatula differs from other genera in the family Virgulariidae by the presence of a conspicuous fan-shaped armature subtending each polyp leaf, comprised of relatively robust sclerites. Of the five described genera in the family, only Stylatula, Acanthoptilum, and Scytalium have sclerites in the rachis and polyp leafs, while Virgularia and Scytaliopsis do not.

Physically Sound Hamiltonian Formulation of the Dynamical Casimir Effect

description: Recently [J. Haro and E. Elizalde, Phys. Rev. Lett. {\bf 97}, 130401 (2006)], a Hamiltonian formulation has been introduced in order to address some longstanding severe problems associated with the physical description of the dynamical Casimir effect at all times while the mirrors are moving. Here we present the complete calculation providing precise details, in particular, of the regularization procedure, which is decisive for the correct derivation of physically meaningful quantities. A basic difference when comparing with the results previously obtained by other authors is the fact that the motion force derived in our approach contains a reactive term --proportional to the mirrors' acceleration. This is of the essence in order to obtain particles with a positive energy all the time during the oscillation of the mirrors --while always satisfying the energy conservation law. A careful analysis of the interrelations among the different results previously obtained in the literature is then carried out. For simplicity, the specific case of a neutral scalar field in one dimension, with one or two partially transmitting mirrors (a fundamental proviso for the regularization issue) is considered in more detail, but our general method is shown to be generalizable, without essential problems (Sect. 2 of this paper), to fields of any kind in two and higher dimensions.

description: Higgs and Goldstone modes, well known in high energy physics, have been realized in a number of condensed matter physics contexts, including superconductivity and magnetism. The Goldstone-Higgs concept is also applicable to and gives rise to new insights on structural phase transitions. Here, we show that the Leggett mode, a collective mode observed in multi-band superconductors, also has an analog in crystallographic phase transitions. Such structural Leggett modes can occur in the phase channel as in the original work of Leggett, \href{https://doi.org/10.1143/PTP.36.901}{Prog.\ Theor.\ Phys.\ \textbf{36}, 901 (1966)}. That is, they are antiphase Goldstone modes (anti-phasons). In addition, a new collective mode can also occur in the amplitude channel, an out-of phase (antiphase) Higgs mode, that should be observable in multi-band superconductors as well. We illustrate the existence and properties of these structural Leggett modes using the example of the pyrochlore relaxor ferroelectric, Cd$_2$Nb$_2$O$_7$.

description: We report the observation of exponential localization of a Bose-Einstein condensate (BEC) released into a one-dimensional waveguide in the presence of a controlled disorder created by laser speckle . We operate in a regime allowing AL: i) weak disorder such that localization results from many quantum reflections of small amplitude; ii) atomic density small enough that interactions are negligible. We image directly the atomic density profiles vs time, and find that weak disorder can lead to the stopping of the expansion and to the formation of a stationary exponentially localized wave function, a direct signature of AL. Fitting the exponential wings, we extract the localization length, and compare it to theoretical calculations. Moreover we show that, in our one-dimensional speckle potentials whose noise spectrum has a high spatial frequency cut-off, exponential localization occurs only when the de Broglie wavelengths of the atoms in the expanding BEC are larger than an effective mobility edge corresponding to that cut-off. In the opposite case, we find that the density profiles decay algebraically, as predicted in [Phys. Rev. Lett. 98, 210401 (2007)]. The method presented here can be extended to localization of atomic quantum gases in higher dimensions, and with controlled interactions.

Επίσης, ακολούθησε ανάλυση των κριτηρίων αξιολόγησης της ποιότητας της βιομάζας, καθώς και ενεργειακή ανάλυση αυτής και σε σχέση με άλλα συμβατικά καύσιμα. Ακόμη, έγινε επεξήγηση των σημαντικότερων ρύπων στην ατμόσφαιρα και των εκπομπών τους, από συστήματα θέρμανσης που χρησιμοποιούν είτε βιομάζα είτε άλλα καύσιμα. Έτσι, ακολούθησε νομοθετική υπόσταση από την Ευρωπαϊκή ένωση, που αφορά τα όρια των ρύπων, καθώς και τις εθνικές δεσμεύσεις σε αυτήν. Με άξονα την εθνική κατάσταση, παρουσιάζονται οι διαθέσιμες ποσότητες βιομάζας και διαχωρίζονται με βάση το είδος που ανήκουν.

Ωστόσο, πολλές εταιρείες και ιδιώτες διστάζουν να αναγνωρίσουν τη σημασία και τον αντίκτυπο των τρεχουσών εξελίξεων. Οι τέσσερεις κυριότεροι λόγοι είναι: 1) ο εντυπωσιακός αντίκτυπος της προηγμένης ψηφιοποίησης δεν είναι ακόμη πλήρως αναγνωρισμένος, 2) υπάρχει έλλειψη φαντασίας και στρατηγικής, σε συνδυασμό με αυξανόμενη απρόβλεπτη ικανότητα, 3) υπάρχει έλλειψη ευελιξίας και ανεπαρκής ενθάρρυνση για καινοτομία και 4) υπάρχει έλλειψη κατάλληλων ικανοτήτων και ανεπαρκής κουλτούρα καινοτομίας. Ο κύριος στόχος αυτής της εργασίας, είναι να εστιάσει την προσοχή σε πρακτικές και ερευνητικές απόψεις, σχετικά με το τι γνωρίζουμε και τι πρέπει ακόμα να μάθουμε για τις επιχειρήσεις και τη διαχείριση στην ψηφιακή εποχή. Οι οργανισμοί θα πρέπει να τροποποιήσουν το επιχειρηματικό τους σχέδιο ή την πολιτική τους, σε ένα νέο ψηφιακό επιχειρηματικό μοντέλο, προκειμένου να επιτύχουν τους στόχους τους.

description: The current accelerating phase of the evolution of the universe is considered by constructing most economical cosmic models that use just general relativity and some dominating quantum effects associated with the probabilistic description of quantum physics. Two of such models are explicitly analyzed. They are based on the existence of a sub-quantum potential and correspond to a generalization of the spatially flat exponential model of de Sitter space. The thermodynamics of these two cosmic solutions is discussed, using the second principle as a guide to choose which among the two is more feasible. The paper also discusses the relativistic physics on which the models are based, their holographic description, some implications from the classical energy conditions, and an interpretation of dark energy in terms of the entangled energy of the universe.

description: We have explored the magnetic flux evolution and temperature variation in a coronal-hole region, using Big Bear Solar Observatory (BBSO) deep magnetograms and {\it SOHO}/EIT images observed from 2005 October 10 to 14. For comparison, we also investigated a neighboring quiet region of the Sun. The coronal hole evolved from its mature stage to its disappearance during the observing period. We have obtained the following results: (1) When the coronal hole was well developed on October 10, about 60 % of the magnetic flux was positive. The EUV brightness was 420 counts pixel$^{-1}$, and the coronal temperature, estimated from the line ratio of the EIT 195 Å and 171 Å images, was 1.07 MK. (2) On October 14, when the coronal hole had almost disappeared, 51 % of the magnetic flux was positive, the EUV radiance was 530 counts pixel$^{-1}$, and the temperature was 1.10 MK. (3) In the neighboring quiet region, the fraction of positive flux varied between 0.49 and 0.47. The EUV brightness displayed an irregular variation, with a mean value of 870 counts pixel$^{-1}$. The temperature was almost constant at 1.11 MK during the five-day observation. Our results demonstrate that in a coronal hole less imbalance of the magnetic flux in opposite polarities leads to stronger EUV brightness and higher coronal temperatures.
Self-help in mental health : operationalizing a conceptual model
Creators: name: Pulcins, Indra R.
Publisher: name: University of British Columbia
Year: 2010

description: This study aims to examine the self-help mode of care giving in mental health, especially the manner in which the working self-help model differs from its theoretical counterpart. For this purpose, a conceptual model of operationalizing self-help has been developed. This model traces the process of establishing self-help groups, from theory to practice, and incorporates the barriers such groups may face in becoming a viable alternative to the current health care system. These include the effects of public policy, the professional and the community. The results of this study, based on empirical evidence collected in Vancouver, B.C., suggest that at least to some extent, this model does accurately depict the processes involved with the operationalization of a self-help model, as well as the factors impinging on a full realization of self-help goals. Both public policy and professional influences serve to act as direct constraints to the full implementation of self-help. The community does not share this characteristic, partially due to favourable zoning policy in Vancouver. In spite of these barriers, self-help groups are able to function as an effective alternative. However, it is demonstrated that some of their original goals have not been fulfilled. In conclusion, a theoretical perspective, in the context of Marx and Weber, is outlined, thereby suggesting some of the broader issues associated with implementing a self-help model.
Diffuse Ionized Gas in the Dwarf Irregular Galaxy DDO 53

description: The spectral characteristics throughout the dwarf irregular galaxy DDO 53 are studied. The results are very similar to those for other irregular galaxies: high excitation and low values of the [SII]/Halpha ratio. The most likely ionization source is photon leakage from the classical HII regions, without any other source, although the interstellar medium of the galaxy is quite perturbed. Moreover, the physical conditions throughout the galaxy do not change very much because both the photon leakage percentage and the ionization temperature are very similar. In addition, the determined metal content for two HII regions indicates that DDO 53 is a low-metallicity galaxy.

A Spitzer Study of Debris Disks In The Young Nearby Cluster NGC 2232: Icy Planets Are Common Around ~ 1.5--3 Solar-Mass Stars

description: We describe Spitzer IRAC and MIPS observations of the nearby 25 Myr-old open cluster NGC 2232. Combining these data with ROSAT All-Sky Survey observations, proper motions, and optical photometry/spectroscopy, we construct a list of highly probable cluster members. We identify 1 A-type star, HD 45435, with definite excess emission at 4.5--24 micron indicative of debris from terrestrial planet formation. We also identify 2--4 late-type stars with possible 8 micron excesses, and 8 early-type stars with definite 24 micron excesses. Constraints on the dust luminosity and temperature suggest that the detected excesses are produced by debris disks. From our sample of B and A stars, stellar rotation appears correlated with 24 micron excess, a result expected if massive primordial disks evolve into massive debris disks. To explore the evolution of the frequency and magnitude of debris around A-type stars, we combine our results with data for other young clusters. The frequency of debris disks around A-type stars appears to increase from ~ 25% at 5 Myr to ~ 50--60% at 20--25 Myr. Older A-type stars have smaller debris disk frequencies: ~ 20% at 50--100 Myr. For these ages, the typical level of debris emission rises from 5--20 Myr and then declines. Because 24 micron dust emission probes icy planet formation around A-type stars, our results suggest that the frequency of icy planet formation is eta(i) > 0.5--0.6. Thus, most A-type stars (approx. 1.5--3 Msun) produce icy planets.

description: Choosing optimal representation methods of atomic and electronic structures is essential when machine learning properties of materials. We address the problem of representing quantum states of electrons in a solid for the purpose of machine leaning state-specific electronic properties. Specifically, we construct a fingerprint based on energy decomposed operator matrix elements (ENDOME) and radially decomposed projected density of states (RAD-PDOS), which are both obtainable from a standard density functional theory (DFT) calculation. Using such fingerprints we train a gradient boosting model on a set of 46k G$_0$W$_0$ quasiparticle energies. The resulting model predicts the self-energy correction of states in materials not seen by the model with a mean absolute error of 0.14 eV. By including the material's calculated dielectric constant in the fingerprint the error can be further reduced by 30%, which we find is due to an enhanced ability to learn the correlation/screening part of the self-energy. Our work paves the way for accurate estimates of quasiparticle band structures at the cost of a standard DFT calculation.

description: We report incoherent quasielastic neutron scattering experiments on the thermotropic liquid crystal 4-n-cyano-4'-octylbiphenyl. The combination of time-of-flight and backscattering data allows analyzing the intermediate scattering function over about three decades of relaxation times. Translational diffusion and uniaxial molecular rotations are clearly identified as the major relaxation processes in respectively the nanosecond and picosecond time scales. The comparison with literature data obtained by other techniques is discussed.

description: We study the synchronized state in a population of network-coupled, heterogeneous oscillators. In particular, we show that the steady-state solution of the linearized dynamics may be written as a geometric series whose subsequent terms represent different spatial scales of the network. Namely, each addition term incorporates contributions from wider network neighborhoods. We prove that this geometric expansion converges for arbitrary frequency distributions and for both undirected and directed networks provided that the adjacency matrix is primitive. We also show that the error in the truncated series grows geometrically with the second largest eigenvalue of the normalized adjacency matrix, analogously to the rate of convergence to the stationary distribution of a random walk. Lastly, we derive a local approximation for the synchronized state by truncating the spatial series, at the first neighborhood term, to illustrate the practical advantages of our approach.

description: The need to visualize large social networks is growing as hardware capabilities make analyzing large networks feasible and many new data sets become available. Unfortunately, the visualizations in existing systems do not satisfactorily answer the basic dilemma of being readable both for the global structure of the network and also for detailed analysis of local communities. To address this problem, we present NodeTrix, a hybrid representation for networks that combines the advantages of two traditional representations: node-link diagrams are used to show the global structure of a network, while arbitrary portions of the network can be shown as adjacency matrices to better support the analysis of communities. A key contribution is a set of interaction techniques. These allow analysts to create a NodeTrix visualization by dragging selections from either a node-link or a matrix, flexibly manipulate the NodeTrix representation to explore the dataset, and create meaningful summary visualizations of their findings. Finally, we present a case study applying NodeTrix to the analysis of the InfoVis 2004 coauthorship dataset to illustrate the capabilities of NodeTrix as both an exploration tool and an effective means of communicating results.

description: Two-dimensional (2D) semiconducting microcavity, where exciton-polaritons can be formed, constitues a promising setup for exploring and manipulating various regimes of light-matter interaction. Here, the coupling between 2D excitons and metallic cavity photons is studied by using first-principles propagator technique. The strength of exciton-photon coupling is characterised by its Rabi splitting to two exciton-polaritons, which can be tuned by cavity thickness. Maximum splitting of 128 meV is achieved in phosporene cavity, while remarkable value of about 440 meV is predicted in monolayer hBN device. The obtained Rabi splittings in WS$_2$ microcavity are in excellent agreement with the recent experiments. Present methodology can aid in predicting and proposing potential setups for trapping robust 2D exciton-polariton condensates.

description: Accurate and homogeneous atmospheric parameters (Teff, log (g), Vt, [Fe/H]) are derived for 74 FGK non-variable supergiants from high-resolution, high signal-to-noise ratio, echelle spectra. Extremely high precision for the inferred effective temperatures (10-40 K) is achieved by using the line-depth ratio method. The new data are combined with atmospheric values for 164 classical Cepheids, observed at 675 different pulsation phases, taken from our previously published studies. The derived values are correlated with unreddened B-V colours compiled from the literature for the investigated stars in order to obtain an empirical relationship of the form: (B-V)o = 57.984 - 10.3587(log Teff)^2 + 1.67572(log Teff)^3 - 3.356(log (g)) + 0.0321(Vt) + 0.2615[Fe/H] + 0.8833((log (g))(log Teff)). The expression is used to estimate colour excesses E(B-V) for individual supergiants and classical Cepheids, with a precision of +-0.05 mag. for supergiants and Cepheids with n=1-2 spectra, reaching +-0.025 mag. for Cepheids with n>2 spectra, matching uncertainties for the most sophisticated photometric techniques. The reddening scale is also a close match to the system of space reddenings for Cepheids. The application range is for spectral types F0--K0 and luminosity classes I and II.

A note on q-Gaussians and non-Gaussians in statistical mechanics

description: The sum of $N$ sufficiently strongly correlated random variables will not in general be Gaussian distributed in the limit N\to\infty. We revisit examples of sums x that have recently been put forward as instances of variables obeying a q-Gaussian law, that is, one of type (cst)\times[1-(1-q)x^2]^{1/(1-q)}. We show by explicit calculation that the probability distributions in the examples are actually analytically different from q-Gaussians, in spite of numerically resembling them very closely. Although q-Gaussians exhibit many interesting properties, the examples investigated do not support the idea that they play a special role as limit distributions of correlated sums.

description: Within the quantum affine algebra representation theory we construct linear covariant operators that generate the Askey-Wilson algebra. It has the property of a coideal subalgebra, which can be interpreted as the boundary symmetry algebra of a model with quantum affine symmetry in the bulk. The generators of the Askey-Wilson algebra are implemented to construct an operator valued $K$- matrix, a solution of a spectral dependent reflection equation. We consider the open driven diffusive system where the Askey-Wilson algebra arises as a boundary symmetry and can be used for an exact solution of the model in the stationary state. We discuss the possibility of a solution beyond the stationary state on the basis of the proposed relation of the Askey-Wilson algebra to the reflection equation.

description: We study the conductive and convective states of phase-change of pure water in a rectangular container where two opposite walls are kept respectively at temperatures below and above the freezing point and all the other boundaries are thermally insulating. The global ice content at the equilibrium and the corresponding shape of the ice-water interface are examined, extending the available experimental measurements and numerical simulations. We first address the effect of the initial condition, either fully liquid or fully frozen, on the system evolution. Secondly, we explore the influence of the aspect ratio of the cell, both in the configurations where the background thermal-gradient is antiparallel to the gravity, namely the Rayleigh-Bénard (RB) setting, and when they are perpendicular, i.e., vertical convection (VC). We find that for a set of well-identified conditions the system in the RB configuration displays multiple equilibrium states, either conductive rather than convective, or convective but with different ice front patterns. The shape of the ice front appears to be always determined by the large scale circulation in the system. In RB, the precise shape depends on the degree of lateral confinement. In the VC case the ice front morphology is more robust, due to the presence of two vertically stacked counter-rotating convective rolls for all the studied cell aspect-ratios.

description: Modern Pelargonium crispum hybrids (section Pelargonium) show low genetic and phenotypic variation due to the domestication effect. Species of the sections Cortusina, Ligularia, and Pelargonium are potential breeding partners at the diploid level (2n = 2x = 22). Five P. × crispum cultivars were used as seed parents and pollinated with one genotype of P. grandiflorum (section Pelargonium) and three genotypes of P. fulgidum (section Ligularia). In both combinations, embryo rescue was necessary. Embryos were rescued and cultured on Murashige & Skoog medium supplemented with phytohormones. After callus and adventitious shoot regeneration 15 viable interspecific hybrids were obtained from crossbreeding with P. grandiflorum and 11 intersectional hybrids from crossings with P. fulgidum, respectively. The hybrids were cultivated in the greenhouse until flowering. Their hybrid character was evident due to the intermediate morphological traits. Molecular investigations using dp-RAPD analysis confirmed this. Within the F1 population P. × crispum with P. grandiflorum three hybrids and after crossing with P. fulgidum one hybrid possessed larger flowers and fully developed anthers, respectively. Their ploidy level was confirmed as tetraploid using flow cytometry. Therefore, a spontaneous polyploidisation occurred during in vitro regeneration. The tetraploid F1 hybrids are fertile and could be used for further breeding.

description: Broad Fe II emission is a prominent feature of the optical and ultraviolet spectra of quasars. We report on a systematical investigation of optical Fe II emission in a large sample of 4037 z < 0.8 quasars selected from the Sloan Digital Sky Survey. We have developed and tested a detailed line-fitting technique, taking into account the complex continuum and narrow and broad emission-line spectrum. Our primary goal is to quantify the velocity broadening and velocity shift of the Fe II spectrum in order to constrain the location of the Fe II-emitting region and its relation to the broad-line region. We find that the majority of quasars show Fe II emission that is redshifted, typically by ~ 400 km/s but up to 2000 km/s, with respect to the systemic velocity of the narrow-line region or of the conventional broad-line region as traced by the Hbeta line. Moreover, the line width of Fe II is significantly narrower than that of the broad component of Hbeta. We show that the magnitude of the Fe II redshift correlates inversely with the Eddington ratio, and that there is a tendency for sources with redshifted Fe II emission to show red asymmetry in the Hbeta line. These characteristics strongly suggest that Fe II originates from a location different from, and most likely exterior to, the region that produces most of Hbeta. The Fe II-emitting zone traces a portion of the broad-line region of intermediate velocities whose dynamics may be dominated by infall.
