description: We study the importance of baryonic physics on predictions of the matter power spectrum as it is relevant for forthcoming weak lensing surveys. We quantify the impact of baryonic physics using a set of three cosmological numerical simulations. Each simulation has the same initial density field, but models a different set of physical processes. The first simulation evolves the density field using gravity alone, the second includes non-radiative gasdynamics, and the third includes radiative heating and cooling of baryons, star formation, and supernova feedback. We find that baryonic processes alter predictions for the matter power spectrum significantly relative to models that include only gravitational interactions. Our results imply that future weak lensing experiments such as LSST and SNAP will be very sensitive to the poorly-understood physics governing the nonlinear evolution of the baryonic component of the universe. The net effect is significantly larger in the case of the model with cooling and star formation, in which case our results imply that contemporary surveys such as the CFHT Wide survey may also be sensitive to baryonic processes. In particular, this effect could be important for forecasts of the constraining power of future surveys if information from scales larger than l ~ 1000 is included in the analysis. We find that deviations are caused primarily by the rearrangement of matter within individual dark matter halos relative to the gravity-only case, rather than a large-scale rearrangement of matter. Consequently, we propose a simple model, based on the phenomenological halo model of dark matter clustering, for baryonic effects that can be used to aid in the interpretation of forthcoming weak lensing data.

Είναι γεγονός ότι οι ομάδες διέπονται από πληθώρα χαρακτηριστικών. Ωστόσο, τα χαρακτηριστικά που θα αναλυθούν στην παρούσα έρευνα είναι η σύνθεση και η συνοχή τους, καθώς και η συναλλαγή ηγέτη-μέλους. Πιο συγκεκριμένα, τα χαρακτηριστικά αυτά θα μελετηθούν, χρησιμοποιώντας ως υποκείμενο τον Σύλλογο Διδασκόντων των δημοτικών σχολείων και ερευνώντας την επίδραση της σύνθεσής του και του ρόλου του διευθυντή στη συνοχή της ομάδας αυτής. Για να υλοποιηθεί το ερευνητικό κομμάτι της εργασίας, χρησιμοποιήθηκαν ως δείγμα 110 ερωτηματολόγια, τα οποία είχαν συμπληρωθεί από εκπαιδευτικούς που εργάζονται σε δημοτικά σχολεία. Χρησιμοποιώντας το SPSS ως εργαλείο στατιστικής ανάλυσης, πραγματοποιήθηκε η διεξαγωγή των αποτελεσμάτων, τα οποία επιβεβαίωσαν τις υποθέσεις που τέθηκαν· πρώτον, ότι η σύνθεση του Συλλόγου Διδασκόντων επηρεάζει τη συνοχή του και δεύτερον, ότι οι σχέσεις διευθυντή-εκπαιδευτικού επίσης, επηρεάζουν τη συνοχή της ομάδας αυτής
description: Teams are an integral part of any organization, whether it is an educational organization or a kind of business. It is true that teams have a variety of characteristics. However, the characteristics which are going to be analyzed in this research are teams’ composition and cohesion, as well as leader-member exchange. In particular, these characteristics will be studied, having as subject teachers’ association of primary schools and by analyzing the impact of its composition and the role of the principal on the cohesion of this group. In order to conduct the research part of the dissertation, a sample of 110 questionnaires was answered by teachers working in primary schools. Using SPSS as a statistics analysis tool, the results were carried out, leading to confirmation of the assumptions that had been made; first, that the composition of teachers association influences its cohesion and second, that principal-teacher relationships also, affect the coherence of this team
Anomalous scaling and gapless fermions of d-wave superconductors in magnetic field

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The problem of d-wave quasiparticles in a weakly disordered Abrikosov vortex lattice is studied. Starting with a periodic lattice, the topological structure of the magnetic crystal momenta of gapless fermions is found for the particle-hole symmetric case. If in addition the site centered inversion symmetry is present, both the location and the number of the gapless fermions can be determined using an index theorem. In the case of spatially aperiodic vortex array, Simon and Lee scaling is found to be violated due to a quantum anomaly. The electronic density of states is found to scale with the root-mean-square vortex displacement as $\sqrt{H}f(\bu_{rms}^2/ξ^2)$, while thermal conductivity is H-independent, but {\it different} from the H=0 case.

description: A novel medium manganese steel named Novalloy with composition Fe-8.3Mn-3.8Al-1.8Si-0.5C-0.06V-0.05Sn was developed and thermomechanically processed through hot rolling and intercritical annealing. The steel possessed a yield strength of 1 GPa, tensile strength of 1.13 GPa and ductility of 41\%. In order to study the effect of cold rolling after intercritical annealing on subsequent tensile properties, the steel was further cold rolled up to 20\% reduction. After cold rolling, it was observed that the strain hardening rate increased continuously with increasing cold rolling reduction but without a significant drop in ductility during subsequent tensile tests. The microstructural evolution with cold rolling reduction was analysed to understand the mechanisms behind this enhanced TRIP effect. It was found that cold rolling activated additional twinning systems which provided a large number of potent nucleation sites for strain induced martensite to form during subsequent tensile tests.

Oversampling in Relation to Differential Regional Response Rates
Creators: name: Pickery, Jan
name: Carton, Ann
Publisher: name: European Survey Research Association
Year: 2008
Subjects: sample design; unit nonresponse; multilevel analysis

description: Response rates of face-to-face surveys often show regional variation. In larger cities e.g., response typically will be lower than in smaller villages. Following current survey practices, substitution of survey non-respondents is no longer recommended. In order to achieve an adequate regional representation of the population in a survey, differential regional oversampling can be an option. We show how regional ineligible rates and response rates of previous surveys can be used in a multilevel analysis to obtain residuals that form the basis for the computation of an ineligible correction and a regional oversampling factor for subsequent surveys. We argue that this oversampling design is a good alternative or complement to nonresponse weighting. We illustrate our approach with the sampling procedure used for the last edition of the yearly survey on social and cultural changes in the Flemish region.

The strong coupling Kondo lattice model as a Fermi gas
Creators: name: Ostlund, S.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The strong coupling half-filled Kondo lattice model is an important example of a strongly interacting dense Fermi system for which conventional Fermi gas analysis has thus far failed. We remedy this by deriving an exact transformation that maps the model to a dilute gas of weakly interacting electron and hole quasiparticles that can then be analyzed by conventional dilute Fermi gas methods. The quasiparticle vacuum is a singlet Mott insulator for which the quasiparticle dynamics are simple. Since the transformation is exact, the electron spectral weight sum rules are obeyed exactly. Subtleties in understanding the behavior of electrons in the singlet Mott insulator can be reduced to a fairly complicated but precise relation between quasiparticles and bare electrons. The theory of free quasiparticles can be interpreted as an exactly solvable model for a singlet Mott insulator, providing an exact model in which to explore the strong coupling regime of a singlet Kondo insulator.

description: We introduce an elementary optical gate for expanding polarization entangled W states, in which every pair of photons are entangled alike. The gate is composed of a pair of 50:50 beamsplitters and ancillary photons in the two-photon Fock state. By seeding one of the photons in an $n$-photon W state into this gate, we obtain an $(n+2)$-photon W state after post-selection. This gate gives a better efficiency and a simpler implementation than previous proposals for $\rm W$-state preparation.

A Heterotic Flux Background and Calibrated Five-Branes

Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider, in flux compactification of heterotic string theory, spacetime-filling five-branes. Stabilizing the fivebrane involves minimizing the combined energy density of the tension and a Coulomb potential associated with an internal 2-dimensional wrapping. After reviewing the generalized calibration under such circumstances, we consider a particular internal manifold based on a $T^2$ bundle over a conformally rescaled $K3$. Here, we find two distinct types of wrapping. In one class, the fivebrane wraps the fibre $T^2$ which belongs to a cyclic homotopy group. The winding number is not extensive, yet it maps to D3-brane number under a U-duality map to type IIB side. We justify this by comparing properties of the two sides in detail. Fivebranes may also wrap a topological 2-cycle of K3, by saturating a standard calibration requirement with respect to a closed Kähler 2-form $J_{K3}$ of $K3$. We close with detailed discussion on F-theory dual of these objects and related issues.

The Three-Step Test-Interview (TSTI): An observation-based method for pretesting self-completion questionnaires

description: Three-Step Test-Interview (TSTI) is a method for pretesting a self-completion questionnaire by first observing actual instances of interaction between the instrument and respondents (the response process) before exploring the reasons for this behavior. The TSTI consists of the following three steps:
1. (Respondent-driven) observation of response behavior.
2. (Interviewer-driven) follow-up probing aimed at remedying gaps in observational data.
3. (Interviewer-driven) debriefing aimed at eliciting experiences and opinions.
We describe the aims and the techniques of these three steps, and then discuss pilot studies in which we tested the feasibility and the productivity of the TSTI by applying it in testing three rather different types of questionnaires. In the first study, the quality of a set of questions about alcohol consumption was assessed. The TSTI proved to be productive in identifying problems that resulted from a mismatch between the ‘theory’  underlying the questions on the one hand, and features of a respondent’s actual behavior and biography on the other hand. In the second pilot study, Dutch and Norwegian versions of an attitude scale, the 20-item Illegal Aliens Scale, were tested. The TSTI appeared to be productive in identifying problems that resulted from different ‘response strategies’. In the third pilot, a two-year longitudinal study, the TSTI appeared to be an  effective method for documenting processes of ‘response shift’ in repeated measurements of health-related Quality of Life  (QoL).

The Effect of Incentives on Response Rates and Panel Attrition: Results of a Controlled Experiment
Creators: name: Castiglioni, Laura
name: Pforr, Klaus
name: Krieger, Ulrich
Publisher: name: European Survey Research Association
Year: 2008
Subjects: panel attrition; incentives; nonresponse; CAPI

description: Steadily declining response rates lead to an increased usage of incentives in all kind of surveys. As for mail surveys, much empirical evidence supporting the usage of unconditional incentives is available (Berk, Mathiowetz, Ward and White 1987; Church 1993). For face-to-face studies, however, fewer results are available, and even less often in experimental settings (Martin, Abreu and Winters 2001; Singer, Hoewyk, Gebler, Raghunathan and McGonagle 1999). We conducted a three wave panel CAPI survey (N=600), where respondents were randomly assigned to three experimental groups: the first group received an unconditional incentive in form of a 10 Euro voucher, the second group was promised a 10 Euro voucher conditional upon participation, the third group was a control group that received no incentive. The allocation to a given experimental group was constant across the three waves and interviewers were kept blind to the experimental conditions. This research adds to the methodological literature in several ways: firstly, we compared the effectiveness of prepaid and conditional monetary incentives in a face-to-face interview in cross-sectional and longitudinal perspective, and found that conditional incentives performed significantly better in retaining respondents till the third wave. Secondly, we controlled for accurateness of the interviewers’ work on the field, and found evidence that improving selection and training of interviewers remains mandatory, since poor quality in the interviewer pool cannot be compensated by incentives.

description: Robin's criterion states that the Riemann Hypothesis (RH) is true if and only if Robin's inequality sum_{d|n}d=5041, where gamma denotes the Euler(-Mascheroni) constant. We show by elementary methods that if n>=37 does not satisfy Robin's criterion it must be even and is neither squarefree nor squarefull. Using a bound of Rosser and Schoenfeld we show, moreover, that n must be divisible by a fifth power >1. As a consequence we infer that RH holds true if and only if every natural number divisible by a fifth power >1 satisfies Robin's inequality.

description: To maintain uninterrupted time series, surveys conducted by  national statistical institutes are often kept unchanged as long as possible. When a change is proposed to improve the methods, it may affect the continuity of these series. It is important to  minimise the impact so as to minimise the inconvenience for users. In this paper we set out the steps in an orderly transition, provide practical guidance on how to minimise discontinuities, and review methods for dealing with discontinuities if they arise so as to maintain a consistently-estimated series.

description: In this article we examine the effect of a prepaid incentive on cooperation rates among ethnic minorities in the Netherlands. We find that the incentive did have a substantial positive effect on the cooperation rates among native sampled units and Western foreigners. Among Non-Western foreigners this effect was only modest. Furthermore, we also matched ethnic minorities with native sampled units using propensity score matching to compare the effect of the incentive on the cooperation rates among ethnic minorities and ‘comparable’ native sampled units. We found that the increase in cooperation rate was larger among natives compared to the increase in cooperation rate among ethnic minorities.

Resource leveling and linear scheduling
Creators: name: Dubey, Ashish
Publisher: name: University of British Columbia
Year: 2008

description: Resource leveling in the context of linear scheduling has been explored in this thesis. Multilocation projects such as high rise construction, bridges and so forth have special characteristics which should be taken into account in resource leveling procedures - e.g., flow line characteristics should be maintained or a specified location execution sequence must be followed. The Minimum Moment Algorithm for resource leveling by Harris has been used as a starting point to develop a modified algorithm to treat linear scheduling. Further modifications have been made to accommodate activities with variable resource usage profiles. The new algorithm has been named the "Modified Minimum Moment Algorithm". The research version of the REPCON Construction management information System has been used for the testing of the algorithm. The multilocation activity modeling structures of REPCON have been used to define linear activity types. One constraint on the leveling algorithm is that these activity types must maintain their attributes when subjected to leveling, e.g., a continuous activity must maintain free float equal to zero between its intermediate locations and the ordered activity must follow the specified location sequence. The algorithm has been programmed and tested on several examples. Resource histograms

description: We prove an accuracy threshold theorem for fault-tolerant quantum computation based on error detection and postselection. Our proof provides a rigorous foundation for the scheme suggested by Knill, in which preparation circuits for ancilla states are protected by a concatenated error-detecting code and the preparation is aborted if an error is detected. The proof applies to independent stochastic noise but (in contrast to proofs of the quantum accuracy threshold theorem based on concatenated error-correcting codes) not to strongly-correlated adversarial noise. Our rigorously established lower bound on the accuracy threshold, 1.04 \times 10^{-3}, is well below Knill's numerical estimates.

Non-response in a survey among immigrants in Denmark
Creators: name: Deding, Mette

Publisher: name: European Survey Research Association
Year: 2008
Subjects: Non-response; non-contacts; refusals; immigrants

description: The purpose of this paper is to analyse the character of response bias in a Danish survey among native Danes and immigrants from Turkey, Iran and Pakistan and thus enable the tailoring of future surveys to particular immigrants groups. We find that both contact rates and cooperation rates are lower for immigrants, leading to a significantly lower overall response rate. We also find important differences between groups - immigrants from Pakistan are especially difficult to reach, while refusals are particularly high among those from Turkey. Language is likewise important as a very large share of women could not be interviewed in Danish. We analyse not only the determinants of the probability of contact and the probability of cooperation but also the determinants of overall nonresponse, by looking at individual characteristics and observable interviewer characteristics. We find that the characteristics of the sample persons are important for both contact and cooperation rates, with different factors affecting each. Yet none of the observable interviewer characteristics appear to affect the response rate. Furthermore, after controlling for all the other variables, we find that the lower probability of response among immigrants compared to native Danes persists. The analysis clearly points to the need for
tailoring surveys directed to immigrant groups to avoid response bias.

We derive the Ford-Parker formula for the 2+1 case, which can be used to compute the radiated quantum flux in the geometric optics approximation. It is shown that no particles are created when the collapse ends in a naked singularity, unlike the 3+1 case. When the collapse ends in a BTZ black hole, we recover the expected Hawking radiation.

Comparing Sampling and Estimation Strategies in Establishment Populations
Creators: name: Henry, Kimberly A
name: Valliant, Richard
Publisher: name: European Survey Research Association
Year: 2009
Subjects: best linear unbiased predictor; deep stratification; general regression estimator, measure of heteroscedasticity, optimal sample, robust variance estimation; weighted balance

description: Population structure is a key determinant of the efficiency of sampling plans and estimators.  Variables in many establishment populations have structures that can be described by simple linear models with a single auxiliary variable and a variance related to some power of that auxiliary.  If a working model can be devised that is a good approximation to the population structure, then very efficient sample designs and estimators are possible.  This study compares alternative strategies of (i) selecting a pilot study to estimate the variance power and using that estimate to select a main sample and (ii) selecting a only main sample based on an educated guess about the variance power.  We also examine a number of sampling plans, including probability proportional to size, deep stratification based on a measure of size, and weighted balanced sampling.  Population totals are estimated by best linear unbiased predictors, general regression estimators, and some other choices often used in practice.

The effect of ammonial loading, solids retention time and operating temperature on the biological nitrification and denitrification of high ammonia landfill leachate
Creators: name: Azevedo, Barry
Publisher: name: University of British Columbia
Year: 2008

description: The effect of ammonia loading, solids retention time and operating temperature (20, 17, 14, 12 and 10 °C) on the treatment of high ammonia landfill leachate (200, 300, 600, 1000, 1500 and 2000 mg NH4-N/L), was investigated. Two biological, single-sludge, nitrification-predenitrification systems were operated in parallel; one with a 10 day aerobic SRT, and the other with a 20 day aerobic SRT. The study consisted of two phases: an ammonia loading phase and a cold temperature phase. From the ammonia loading phase, it was found that at an influent leachate ammonia level of 1500 mg N/L, both systems produced an effluent of <1 mg NH4-N/L and approximately 170 mg NO.--N/L. Aerobic nitrite accumulation was observed and was likely a factor in a parallel decrease in the COD:NOx ratio from approximately 6:1 to 4:1. At the leachate ammonia level of 1500 mg N/L, "free" ammonia levels in the anoxic reactor were estimated to have been 20 mg N/L. This elevated anoxic "free" ammonia level did not appear inhibitory to either the ammonia oxidizers (Nitrosomonas) or to the denitrifiers, but may have inhibited nitrite oxidizers (Nitrobacter), thereby resulting in nitrite accumulation. When the influent ammonia concentration was raised from 1500 to 2000 mg N/L, nitrification in both systems was observed to decrease from 100 % to approximately 20 %. Several factors may have contributed to the failure of nitrification including: insufficient dissolved oxygen, solids/foaming problems, and levels of anoxic "free" ammonia inhibitory to Nitrosomonas. During the cold temperature phase, the temperature was decreased from 20 to 10 °C while maintaining the simulated leachate ammonia level at 1500 mg N/L. Aerobic nitrite accumulation and rising aerobic BOD5 was observed to begin at 14 °C. When the temperature was decreased from 12 °C to 10 °C, nitrification was observed, in both SRT systems, to decrease from approximately 95 % to approximately 20 %. In the 10 day SRT system, denitrification decreased from 99 % to30 %; in the 20 day SRT system, denitrification decreased from 99 % to 82 %. Based on the rise of aerobic nitrite, and only partial failure of denitrification, cold temperature was deemed responsible for nitrification failure, which for the 10 day SRT system, subsequently precipitated the failure of denitrification. In both awstems, nitrification was re-established at 10 °C, by ceasing to waste solids and by stopping methanol addition.
Meteoritical and dynamical constraints on the growth mechanisms and formation times of asteroids and Jupiter
Creators: name: Scott, Edward R. D.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Peak temperatures inside meteorite parent bodies are closely linked to accretion times. Most iron meteorites come from bodies that accreted <0.5 Myr after CAIs formed and were melted by 26Al and 60Fe, probably inside 2 AU. Chondrite groups accreted intermittently over 4 Myr starting 1 Myr after CAIs formed when planetary embryos may already have formed at ~1 AU. Meteorite evidence precludes accretion of late-forming chondrites on the surface of early-formed bodies; instead chondritic and non-chondritic meteorites probably formed in separate planetesimals. Maximum metamorphic temperatures in chondrite groups correlate inversely with mean chondrule age, as expected for 26Al heating. Dynamical models suggest that asteroids accreted before Jupiter. Therefore Jupiter probably reached its current mass >3-5 Myr after CAIs formed. This precludes formation of Jupiter via a gravitational instability <1 Myr after the solar nebula formed, and strongly favors core accretion. Shocks formed by gravitational instabilities in the disk, proto-Jupiter, or by planetary embryos may have produced some chondrules. The minimum lifetime for the solar nebula of 3-5 Myr inferred from CAI and chondrule ages may exceed the median 3 Myr lifetime for protoplanetary disks, but is well within the total 1-10 Myr range. Shorter formation times for extrasolar planets may help to explain why their orbits are unlike those of solar giant planets.

description: We present results from a qualitative evaluation of the Spanish-language version of a dietary intake questionnaire and characterize the types of findings which emerged from several rounds of cognitive testing. Cognitive interviews were used to test the Spanish translation of the National Health Interview Survey (NHIS) Cancer Control Supplement dietary questions, with 36 Spanish-speaking and 9 English-speaking participants. Analyses of the results identified (a) translation issues, (b) culture-specific issues, and (c) general design issues that affected both English and Spanish speakers. Results indicated that general design-oriented difficulties were particularly frequent. Our findings suggest that when appropriately structured, cognitive interviews that feature flexible probing can be useful for identifying a range of problems in survey translations, even after translations have been developed using currently accepted methods. We make several recommendations concerning practices that may be optimal in the conduct of empirical cross-cultural questionnaire evaluations.

description: Recently, it was pointed out that the mixing phase in the Bs-Bsbar system is large, contrary to the expectations in the Standard Model as well as in minimal flavour violation models. The leptonic decay widths of the D_s meson are also found to be larger than expected. We show how a minimal set of four R-parity violating lambda-prime type couplings can explain both these anomalies. We also point out other phenomenological implications of such new physics.

description: We introduce an integrable lattice discretization of the quantum system of n bosonic particles on a ring interacting pairwise via repulsive delta potentials. The corresponding (finite-dimensional) spectral problem of the integrable lattice model is solved by means of the Bethe Ansatz method. The resulting eigenfunctions turn out to be given by specializations of the Hall-Littlewood polynomials. In the continuum limit the solution of the repulsive delta Bose gas due to Lieb and Liniger is recovered, including the orthogonality of the Bethe wave functions first proved by Dorlas (extending previous work of C.N. Yang and C.P. Yang).

description: Σκοπός της διπλωματικής εργασίας ήταν η μελέτη του φαινομένου της δωροδοκίας από την άποψη της Χριστιανικής Ηθικής. Αρχικά εξετάσαμε την κοινωνική και νομική διάστασή της και πιο συγκεκριμένα την εννοιολογική σχέση της με τη διαφθορά, τη νομική όψη της δωροδοκίας καθώς και το φαινόμενο της Σιμωνίας, δηλαδή τη δωροδοκίας στους κόλπους της ιερωσύνης. Στη συνέχεια αναφερθήκαμε αναλυτικά στην πνευματική διάσταση της δωροδοκίας και ασχοληθήκαμε με την αναφορά παραδειγμάτων αυτής στην Παλαιά και την Καινή Διαθήκη. Ασχοληθήκαμε περαιτέρω με τον προβληματισμό σχετικά με τη σχέση των αναθημάτων με τη δωροδοκία. Επιπλέον μας απασχόλησε η διδασκαλία των Αγίων Πατέρων, μέσω των οποίων εντοπίσαμε τα αίτια και τις συνέπειες της. Τέλος, επισημάναμε τη συμβολή της Χριστιανικής Ηθικής στην αντιμετώπιση της καθώς και τα μέτρα αντιμετώπισης που χρησιμοποιούνται από την πολιτεία
description: The purpose of this dissertation was to study the phenomenon of bribery from the point of new of Christian Ethic. At first we examined the social and legal aspect of Christian Ethic and more specific the semantic relationship of it with corruption, the legal aspect of bribery and the phenomenon of simony which is the bribery among the clergy. Consequently, we indicated extensively the spiritual aspect of bribery and we were concerned with examples of it inside the Old and New Testament. We involved further with the concern about the relation between votive offering and bribery. Moreover, we were interested in Holy Fathers' teachings and through them we detected the causes and the consequences of it. Finally w mentioned the contribution of it into dealing the bribery and all the punitive measures that are used by the State

description: The magnetic-octupole (M3) and electric-quadrupole (E2) transitions between the ground state $3d^{10} ^1S_0$ and the lowest excited $3d^94s$ $(5/2,1/2)$ J = 3 and J = 2 states in the Ni-like tungsten are shown to exhibit a strong dependence on electron density $N_e$ in the range of values typical for tokamak plasmas. Remarkably, the total intensity of these overlapping lines remains almost constant, which may explain the strong emission in the 7.93 Åline observed in tokamak experiments (Neu R et al. 1997 J Phys B {\bf 30} 5057). Utilization of the M3 and E2 line ratios for density diagnostics in high-spectral-resolution experiments is discussed as well.

description: We present new results on the cosmological evolution of the near-infrared galaxy luminosity function, derived from the analysis of a new sample of \~22,000 K(AB) < 22.5 galaxies selected over an area of 0.6 square degrees from the Early Data Release of the UKIDSS Ultra Deep Survey (UDS). Our study has exploited the multi-wavelength coverage of the UDS field provided by the new UKIDSS WFCAM K and J-band imaging, the Subaru/XMM-Newton Deep Survey and the Spitzer-SWIRE Survey. The unique combination of large area and depth provided by this new survey minimises the complicating effect of cosmic variance and has allowed us, for the first time, to trace the evolution of the brightest sources out to z~2 with good statistical accuracy. In agreement with previous studies we find that the characteristic luminosity of the near-infrared luminosity function brightens by 1 magnitude between z=0 and z~2, while the total density decreases by a factor ~2. Using the rest-frame (U-B) colour to split the sample into red and blue galaxies, we confirm the classic luminosity-dependent colour bimodality at z<1. However, the strength of the colour bimodality is found to be a decreasing function of redshift, and seems to disappear by z>1.5. Due to the large size of our sample we are able to investigate the differing cosmological evolution of the red and blue galaxy populations. It is found that the space density of the brightest red galaxies (M_K < -23) stays approximately constant with redshift, and that these sources dominate the bright-end of the luminosity function at redshifts z<1. In contrast, the brightening of the characteristic luminosity and mild decrease in space density displayed by the blue galaxy population leads them to dominate the bright-end of the luminosity function at redshifts z>1.

Στο πλαίσιο αυτού του σκοπού, εξετάζονται τα όσα ανέφερε ο Έλληνας ποιητής, αλλά ταυτόχρονα εξετάζεται και το κλίμα που επικρατούσε τότε στους φιλολογικούς κύκλους στην Ελλάδα. Παρουσιάζεται μια σειρά άρθρων και κειμένων της εποχής, αναφορικά με την εμφάνιση της αυτόματης γραφής, με σκοπό τη δημιουργία μιας, όσον το δυνατόν, πληρέστερης εικόνας. Επιχειρείται, επίσης, η ανάδειξη της αξίας του ελληνικού υπερρεαλισμού, καθώς και η ανάδειξη της συμβολής του ίδιου του Εμπειρίκου για τα ελληνικά γράμματα, αφού δεν έχει αναγνωριστεί στο μέγιστο βαθμό
description: The purpose of the present paper is to investigate the form, which surrealism took in Greece, after the presentation of the theoretical background of the movement by Andreas Empirikos in 1935. Under this purpose, a review of what was said by the Greek poet and the atmosphere in literally circles in Greece back then, are presented. We quote a number of articles and texts of the time, regarding the appearance of automatic writing in Greece, in order to create one, as far as possible, complete picture. We also attempt to highlight the value of Greek surrealism, as well as highlighting the contribution of Empirikos himself for the Greek literature, since it is not recognized to the fullest extent
Entanglement in extended Hubbard models and quantum phase transitions

description: The role of two-point and multipartite entanglement at quantum phase transitions (QPTs) in correlated electron systems is investigated. We consider a bond-charge extended Hubbard model exactly solvable in one dimension which displays various QPTs, with two (qubit) as well as more (qudit) on-site degrees of freedom involved. The analysis is carried out by means of appropriate measures of bipartite/multipartite quantum correlations. It is found that all transitions ascribed to two-point correlations are characterized by an entanglement range which diverges at the transition points. The exponent coincides with that of the correlation length at the transitions. We introduce the correlation ratio, namely, the ratio of quantum mutual information and single-site entanglement. We show that at T=0, it captures the relative role of two-point and multipartite quantum correlations at transition points, generalizing to qudit systems the entanglement ratio. Moreover, a finite value of quantum mutual information between infinitely distant sites is seen to quantify the presence of off-diagonal long-range order induced by multipartite entanglement.
