description: The monochromatic illumination system is constructed to carry out in situ measurements of the response function of the mosaicked CCD imager used in the Sloan Digital Sky Survey (SDSS). The system is outlined and the results of the measurements, mostly during the first 6 years of the SDSS, are described. We present the reference response functions for the five colour passbands derived from these measurements, and discuss column to column variations and variations in time, and also their effects on photometry. We also discuss the effect arising from various, slightly different response functions of the associated detector systems that were used to give SDSS photometry. We show that the calibration procedures of SDSS remove these variations reasonably well with the resulting final errors from variant response functions being unlikely to be larger than 0.01 mag for g, r, i, and z bands over the entire duration of the survey. The considerable aging effect is uncovered in the u band, the response function showing a 30% decrease in the throughput in the short wavelength side during the survey years, which potentially causes a systematic error in photometry. The aging effect is consistent with variation of the instrumental sensitivity in u-band, which is calibrated out. The expected colour variation is consistent with measured colour variation in the catalog of repeated photometry. The colour variation is delta (u-g) ~ 0.01 for most stars, and at most delta (u-g) ~ 0.02 mag for those with extreme colours. We verified in the final catalogue that no systematic variations in excess of 0.01 mag are detected in the photometry which can be ascribed to aging and/or seasonal effects except for the secular u-g colour variation for stars with extreme colours.

The Triple Helix Model and the study of Knowledge Based Inovation Systems

Subjects: subject: Physics and Society (physics.soc-ph)

description: This paper examines the changing nature of knowledge-based innovation systems in light of the dynamic interconnections between the university, industry and government. Industries have to assess in what way and to what extent they decide to internalize R&D functions. Universities position themselves in markets, both regionally and globally. Governments make informed trade-offs between investments in industrial policies, S&T policies, andor delicate and balanced interventions at the structural level. Such policies can be expected to be successful insofar as one can anticipate andor follow trends according to the dynamics of the new technologies in their different phases. The evolutionary perspective in economics can be complemented with a turn towards reflexivity in sociology in order to obtain a richer understanding of how the overlay of communications in university-industry-government relations reshapes the systems of innovations that are currently subjects of debate, policy-making, and scientific study.
title: A Study of the Amount and Quality of Poetry Read on the Primary Grade Level in Selected Utah School Districts
Creators: name: Spencer, Betty Farnsworth
Publisher: name: Utah State University
Year: 1968

description: The primary grade teachers of the Cache, Logan, and Box Elder School Districts were used in this study. A questionnaire was developed that would be an effective measurement of the information needed to evaluate or substantiate the hypothesis which was: It is believed that less than 50 percent of the primary grade children have poetry read to them daily as part of the curriculum. Furthermore, it is believed that much of the poetry read does not meet the standards of "good poetry for children" as measured by experts in this field of learning.
The study revealed that only 11 percent of the children were read to daily. However, the majority of teachers were reading from approved literature for children.

description: Reactive and elastic cross-sections, and rate coefficients, have been calculated for the S(1D)+ D2 (v=0, j=0) reaction using a modified hyperspherical quantum reactive scattering method. The considered collision energy ranges from the ultracold regime, where only one partial wave is open, up to the Langevin regime, where many of them contribute. This work presents the extension of the quantum calculations, which were compared with the experimental results in a previous work, down to energies in the cold and ultracold domains. Results are analyzed and compared with the universal case of the quantum defect theory by Jachymski et al. [Phys. Rev. Lett. 110, 213202 (2013)]. State-to-state integral and differential cross sections are also shown covering the ranges of low-thermal, cold and ultracold collision energy regimes. It is found that at E/k_B T < 1 K there are substantial departures from the expected statistical behavior, and that dynamical features become increasingly important with decreasing collision energy, leading to vibrational excitation.

Relational Motivation for Conformal Operator Ordering in Quantum Cosmology
Creators: name: Anderson, Edward
Publisher: name: arXiv
Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Operator-ordering in quantum cosmology is a major as-yet unsettled ambiguity with not only formal but also physical consequences. We determine the Lagrangian origin of the conformal invariance that underlies the conformal operator-ordering choice in quantum cosmology. It is particularly naturally and simply manifest in relationalist product-type actions (such as the Jacobi action for mechanics or Baierlein-Sharp-Wheeler type actions for general relativity), for which all that is required for the kinetic and potential factors to rescale in compensation to each other. These actions themselves mathematically sharply implementing philosophical principles relevant to whole-universe modelling, the motivation for conformal operator-ordering in quantum cosmology is substantially strengthened. Relationalist product-type actions also give emergent times which amount to recovering Newtonian, proper and cosmic time in the various relevant contexts. The conformal scaling of these actions directly tells us how emergent time scales; if one follows suit with the Newtonian time or the lapse in the more commonly used difference-type Euler--Lagrange or Arnowitt--Deser--Misner type actions, one sees how these too obey a more complicated conformal invariance. Moreover, our discovery of the conformal scaling of the time involved permits relating how it simplifies equations of motion with how affine parametrization simplifies geodesics.

On the possibility of braneworld quintessential inflation

description: We examine the possibility of achieving quintessential inflation, where the same field serves as both inflaton and quintessence, in the context of a five-dimensional braneworld. Braneworld cosmology provides an appropriate environment as it permits inflation with much steeper potentials than the conventional scenario, which is favourable to a late-time quintessence. We explore a wide space of models, together with contemporary observational data, to determine in which contexts such a picture is possible. We find that such a scenario, although attractive, is in fact impossible to achieve for the potentials studied due to the restrictiveness of current data.

title: Estimated Supply Response of Sugar Beet Production to Changes in Profitableness, Box Elder and Cache Counties, Utah, 1967
Creators: name: Spaulding, Brent W.
Publisher: name: Utah State University
Year: 1968

description: The relative profitability of sugar beets and competitive crops were studied in Box Elder and Cache counties, Utah.
Profitability ratios based on enterprise budget data and resource use requirements were used as a basis for comparison. Sugar beets was found to be more profitable than competing crops in returns per acre, in returns to water used and in returns to fixed investment and management. However, sugar beets was found to be less profitable than certain other crops in returns to operating capital and returns to labor. Also, on land rated low in productivity sugar beets was found to be less profitable than most competing crops.
Linear programming techniques were used in studying the production response of sugar beets at various price levels. An aggregated supply curve was developed showing the acreage response in sugar beet production at varying sugar beet prices for the two county area. The price range over which sugar beet acreage was responsive ranged from $11.70 per ton to a high of $16.70 per ton where the maximum acreage permitted in the model was attained.

description: Two near-threshold peaking structures with spin-parities $J^{\mathrm{PC} }=0^{++}$ were recently discovered by the LHCb Collaboration in the $ D_{s}^{+}D_{s}^{-}$ invariant mass distribution of the decay $ B^{+}\rightarrow D_{s}^{+}D_{s}^{-}K^{+}$. The first of them is the resonance $X(3960)$, whereas the second one, $X_0(4140)$, is a structure with the mass around $4140~\mathrm{MeV}$. To explore their natures and model them, we study the hadronic molecule $\mathcal{M}=D_s^{+}D_s^{-}$ and calculate its mass, current coupling, and width. The mass and current coupling of the molecule are extracted from the QCD two-point sum rule analyses by taking into account vacuum condensates up to dimension $10$. To evaluate its full width, we consider the processes $\mathcal{M} \to D_{s}^{+}D_{s}^{-}$, $\mathcal{M} \toη_{c}η^{(\prime)}$, and $\mathcal{ M} \to J/ψϕ$. Partial widths of these decays are determined by the strong couplings $g_i, \ i=1,2,3,4 $ at vertices $\mathcal{M} D_{s}^{+}D_{s}^{-}$, $\mathcal{M}η_{c} η^{(\prime)}$, and $\mathcal{M} J/ψϕ$. They are computed by means of the three-point sum rule method. Predictions for the mass $m=(4117 \pm 85)~\mathrm{MeV}$ and width $Γ_{ \mathcal{M}}=(62 \pm 12)~\mathrm{MeV}$ of the molecule $\mathcal{M}$ are compared with the corresponding LHCb data, and also with our results for the diquark-antidiquark state $X=[cs][\overline{c}\overline{s}]$. We argue that the structure $X_0(4140)$ may be interpreted as the hadronic molecule $ D_s^{+}D_s^{-}$, whereas the resonance $X(3960)$ can be identified with the tetraquark $X$.

description: The accretion of matter onto celestial bodies like black holes and neutron stars is a natural phenomenon that releases up to $40\%$ of the matter's rest-mass energy, which is considered a source of radiation. In active galactic nuclei and X-ray binaries, huge luminosities are observed as a result of accretion. Using isothermal fluid, we examine the accretion and geodesic motion of particles in the vicinity of a spherically symmetric black hole spacetime in the Einstein-$SU(N)$ non-linear sigma model. In the accretion process, the disk-like structure is produced by the geodesic motion of particles near the black hole. We determine the innermost stable circular orbit, energy flux, radiation temperature, and radioactive efficiency numerically. In the equatorial plane, we investigate the mobility of particles with stabilities that form circular orbits. We examine perturbations of a test particle by using restoring forces and particle oscillations in the vicinity of the black hole. We analyze the maximum accretion rate and critical flow of the fluid. Our findings demonstrate how parameter $N$ influences the circular motion of a test particle as well as the maximum accretion rate of the black hole in the Einstein-$SU(N)$ non-linear sigma model.

A Microbiological control of Melampsora medusae Thum. rust on Psuedotsuga menziesii (Mirb.) Franco seedlings
Creators: name: McBride, Richard Phillips
Publisher: name: University of British Columbia
Year: 2011

description: Saprophytic fungi and bacteria were recovered from healthy foliage of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco). The populations of microorganisms on foliage were variable and changed through the growing season. Three species of the bacteria isolated from Douglas fir foliage were used in attempts to control the development of the rust, Melampsora medusae Thum., on Douglas fir seedlings in the greenhouse. Effective control was obtained when Bacillus cereus Frankland and Frankland and B. mycoides Flugge were applied to the seedlings in pure cultures of nutrient broth. The most effective control was obtained from the application of a mixture of these two species and a third unidentified species of Baci1lus in nutrient broth. Less effective control resulted from the application of bacteria suspended in water and cell free filtrates of the bacterial cultures. The numbers of bacteria on the foliage of Douglas fir were estimated using a modification of the soil dilution and bacterial plate count technique. The bacterial populations on foliage of Douglas fir in the greenhouse and in the field were increased by the application of bacteria in nutrient broth and sterile nutrient broth.
Non-parametric Reconstruction of Photon Escape Fraction from Reionization

description: One of the most crucial yet poorly constrained parameters in modelling the ionizing emissivity is the escape fraction of photons from star-forming galaxies. Several theoretical and observational studies have been conducted over the past few years, but consensus regarding its redshift evolution has yet to be achieved. We present here the first non-parametric reconstruction of this parameter as a function of redshift from a data-driven reionization model using a Gaussian Process Regression method. Our finding suggests a mild redshift evolution of escape fraction with a mean value of $4\%,7\%,\sim10\%$ at $z=2,6,12$. However, a constant escape fraction of $6-10\%$ at $z\gtrsim 6$ is still allowed by current data and also matches other reionization-related observations. With the detection of fainter high redshift galaxies from upcoming observations of JWST, the approach presented here will be a robust tool to put the most stringent constraint on escape fraction as well as reionization histories.

description: For the first time, we undertake a systematic examination of the nitrogen abundances for a sample of 35 early-type galaxies spanning a range of masses and local environment. The nitrogen-sensitive molecular feature at 3360Åhas been employed in conjunction with a suite of atomic- and molecular-sensitive indices to provide unique and definitive constraints on the chemical content of these systems. By employing NH3360, we are now able to break the carbon, nitrogen, and oxygen degeneracies inherent to the use of the CN-index. We demonstrate that the NH3360 feature shows little dependency upon the velocity dispersion (our proxy for mass) of the galaxies, contrary to what is seen for carbon- and magnesium-sensitive indices. At face value, these results are at odds with conclusions drawn previously using indices sensitive to both carbon and nitrogen, such as cyanogen (CN). With the aid of stellar population models, we find that the N/Fe ratios in these galaxies are consistent with being mildly-enhanced with respect to the solar ratio. We also explore the dependence of these findings upon environment, by analyzing the co-added spectra of galaxies in the field and the Coma cluster. We confirm the previously found differences in carbon abundances between galaxies in low- and high-density environments, while showing that these differences do not seem to exist for nitrogen. We discuss the implications of these findings for the derivation of the star formation histories in early-type galaxies, and for the origin of carbon and nitrogen, themselves.

description: The objectives of this study was to obtain data on five aspects of officials qualification practices presently used in Utah and to make some justifiable conclusion.
1. Qualification Data requested.
a. Physical Qualification
b. Mental Qualification
c. Previous Experience as an Official and Player
d. Other Related Athletic Experience
e. Basketball Officiating and some existing Problems
The survey compiled was sent to all head coaches of class "A" high schools, in Utah, which included 40 coaches in all, and to 60 class "A" high school officials of Regions 1, 2, and 4. The officials were chosen at random from the Utah High School Activities Association certified officiating bulletin issued yearly.
From the Analysis of the Data the following conclusions were made: (a) Coaches and officials need to recognize what qualifications are presently used and what has to be done to improve these practices. (b) Physical qualifications as a requirement is only an assumption, not a must. (c) The knowledge that one must receive to make him mentally alert appears to be strong in some areas of the state, while in others it only involves reading the rule book and passing the written test. (d) All the athletic experience that one obtains prior to becoming an official, does have the sanction of all offiicials and coaches , for without it a person who wants to become an official can only hope for limited work, or assignments. (e) Any athletic sports activity that a person is associated with has many carryover advantages in the overall performance of an official. (f) Officiating problems as expressed by the data received are extensive . A few examples of the problems are listed below:
1. Crowd reaction
2. Coach reaction
3. Judgment and consistency , etc

description: NGC 6522 has been the first metal-poor globular cluster identified in the bulge by W. Baade. Despite its importance, very few high resolution abundance analyses of stars in this cluster are available in the literature. The bulge metal-poor clusters may be important tracers of the early chemical enrichment of the Galaxy. The main purpose of this study is the determination of metallicity and elemental ratios in individual stars of NGC 6522. High resolution spectra of 8 giants of the bulge globular cluster NGC 6522 were obtained at the 8m VLT UT2-Kueyen telescope with the FLAMES+GIRAFFE spectrograph. Multiband V,I,J,Ks} photometry was used to derive effective temperatures as reference values. Spectroscopic parameters are derived from FeI and FeII lines, and adopted for the derivation of abundance ratios. The present analysis provides a metallicity [Fe/H] = -1.0+-0.2. The alpha-elements Oxygen, Magnesium and Silicon show [O/Fe]=+0.4, [Mg/Fe]=[Si/Fe]= +0.25, whereas Calcium and Titanium show shallower ratios of [Ca/Fe]=[Ti/Fe]=+0.15. The neutron-capture r-process element Europium appears to be overabundant by [Eu/Fe]=+0.4. The neutron-capture s-elements La and Ba are enhanced by [La/Fe]=+0.35 and [Ba/Fe]=+0.5. The large internal errors, indicating the large star-to-star variationin the Ba and Eu abundances, are also discussed. The moderate metallicity combined to a blue Horizontal Branch (BHB), are characteristics similar to those of HP~1 and NGC 6558, pointing to a population of very old globular clusters in the Galactic bulge. Also, the abundance ratios in NGC 6522 resemble those in HP 1 and NGC 6558. The ultimate conclusion is that the bulge is old, and went through an early prompt chemical enrichment.

description: Dark matter clusters on all scales, therefore it is expected that even substructure should host its own substructure. Using the Extragalactic Distance Database, we searched for dwarf galaxy satellites of dwarf galaxies, i.e. satellite-of-satellite galaxies, corresponding to these substructures-of-substructure. Going through HST data of 117 dwarf galaxies, we report the discovery of a dwarf galaxy around the ultra-diffuse M96 companion M96-DF6 at 10 Mpc. Modelling its structural parameters, we find that it is an ultra-faint dwarf galaxy which is 135 times fainter than its host. Based on its close projection to M96-DF6 it is unlikely that their association occurs by chance. We compare the luminosity ratio of this and three other known satellite-of-satellite systems with results from two different cosmological sets of CDM simulations. For the observed stellar mass range of the central dwarf galaxies, the simulated dwarfs have a higher luminosity ratio between the central dwarf and its first satellite ($\approx$10'000) than observed ($\approx$100), excluding the LMC system. No simulated dwarf analog at these observed stellar masses has the observed luminosity ratio. This cannot be due to missing resolution, because it is the brightest subhalos that are missing. This may indicate that there is a satellite-of-satellite (SoS) problem for CDM in the stellar mass range between 10$^6$ and 10$^8$ M$_\odot$ - the regime of the classical dwarf galaxies. However, simulated dwarf models at both a lower ($<10^6$ M$_\odot$) and higher ($>10^8$ M$_\odot$) stellar mass have comparable luminosity ratios. For the higher stellar mass systems, the LMC system is reproduced by simulations, for the lower stellar masses, no observed SoS system has been observed to date. More observations and simulations of SoS systems are needed to assess whether the luminosity ratio is at odds with CDM.

title: The Attitudes of Caseworkers and Supervisors Employed by County Welfare Departments in Box Elder, Cache, and Weber Counties Toward Public Assistance
Creators: name: Fayer, Mardell Lorene
Publisher: name: Utah State University

description: Attitudes of caseworkers and supervisors in public welfare agencies were studied with regard to the following subjects: (1) the public assistance program in Utah, (2) the welfare recipient, (3) family planning as a means of dealing with poverty, (4) government participation in the public assistance program, (5) methods of rehabilitation, (6) community support of welfare agency, and (7) positive and negative aspects of casework. Data were analyzed statistically with regard to age, education, political preference, and sex. An analysis of variance was made, and the F test applied to determine significance levels.
Caseworkers and supervisors responded positively toward the public assistance system in Utah with mean scores high enough to indicate approval though not complete approval of this system. Caseworkers and supervisors expressed a slightly positive attitude toward welfare recipients; they were generally favorable toward family planning as a means of dealing with poverty; and they expressed a positive attitude concerning government participation in the public assistance program. Df the three means of rehabilitation proposed, caseworkers and supervisors unanimously selected the use of individual therapy as their first choice, environmental change and direct financial aid as their second and third choices, respectively, by the majority of respondents. Caseworkers and supervisors felt a need for community support but did not feel they received it. In their opinion the public is poorly informed, has many misconceptions, and is, consequently, negative toward the public assistance system. Male and female caseworkers and supervisors indicated that working with people and helping them with their problems were the most enjoyable aspects of their job; whereas, clerical work and administrative rules and procedures were the least enjoyable aspects. Women liked more aspects of their work than they disliked; whereas, men disliked more aspects than they liked.

description: A naive computation of the correlation functions of fluctuations generated during inflation suffers from logarithmic divergences in the infrared (IR) limit. In this paper, we propose one way to solve this IR divergence problem in the single-field inflation model. The key observation is that the variables that are commonly used in describing fluctuations are influenced by what we cannot observe. Introducing a new perturbation variable which mimics what we actually observe, we propose a new prescription to solve the time evolution of perturbation in which this leakage of information from the unobservable region of the universe is shut off. We give a proof that IR divergences are absent as long as we follow this new scheme. We also show that the secular growth of the amplitude of perturbation is also suppressed, at least, unless very higher order perturbation is discussed.

Creators: name: McConnachie, Peter Ross
Publisher: name: University of British Columbia
Year: 2011

description: Histochemical treatments specific for hyaluronic acid, chondroitin sulphate A/C, chondroitin sulphate B, and heparin, which are biological compounds classed as acid mucopolysaccharides, were applied to a series of Pacific great skate (Raja binoculata) embryos in order to characterize histochemically the acid mucopolysaccharides present in the embryos and to study the events leading to the situation of acid mucopolysaccharides localization in the adult. Embryonic stages examined ranged from early cleavage to immediate prehatching. A progression was observed from; 1. intracellular neutral polysaccharides in cleaving stages through, 2. a combination of extracellular neutral polysaccharides and weakly acidic acid mucopolysaccharides (hyaluronic acid) associated with cell processes in neurulating stages to, 3. extracellular strongly acidic sulphated acid mucopolysaccharides (chondroitin sulphates) in later stages, particularly in areas of cartilage development. In neurulating embryos hyaluronic acid appeared in considerable quantity between some adjacent tissue layers in a smooth layer form suggestive of some developmental significance for this compound. Hyaluronic acid also occurred in a similar form in lesser quantity in post neurulae (17-18 mm. embryos) in close association with developing gut and mesonephros. Results of histological tests in immediate prehatching embryos agreed with previously reported biochemical analyses of shark skins and cartilages i.e. chondroitin sulphate B occurred primarily in the skin and chondroitin sulphate A/c were a major component of the cartilage matrix.

description: Tartu Ülikooli eesmärgiks on rahvusvahelistumine ning teaduse ja hariduse edasise arengu tagamiseks olla tunnustatud konkurentsivõimeline rahvusvaheline teadusülikool. Eurointegratsioonist tulenevad suundumused on tinginud vajaduse määratleda ja planeerida ka arstiteaduskonna tulevikku. Vaatamata ühiskondlikule ebaühtlusele, mis kajastub nii vastuolulises meditsiinisüsteemi arengus kui raskustes kõrghariduse ja teaduse eelisarengu realiseerimises, on riigi ainsa meditsiinialast ülikooliharidust andva õppe- ja teaduskeskusena Tartu Ülikool vastutav kogu valdkonna arengu eest Eestis. Aastatepikkused vaidlused residentuuri rahastamise ja staatuse üle on alles nüüdseks leidnud seadusliku reguleerituse ja sellele vastava rahastamise. Sama problemaatiline on olnud ka kliinikumi kui ainsa diplomieelse õppebaasi õpetuskulude katmise süsteemi väljatöötamine; nüüdseks on see seadusega reguleeritud.

description: The use of Pearson's correlation coefficient in Author Cocitation Analysis was compared with Salton's cosine measure in a number of recent contributions. Unlike the Pearson correlation, the cosine is insensitive to the number of zeros. However, one has the option of applying a logarithmic transformation in correlation analysis. Information calculus is based on both the logarithmic transformation and provides a non-parametric statistics. Using this methodology one can cluster a document set in a precise way and express the differences in terms of bits of information. The algorithm is explained and used on the data set which was made the subject of this discussion.

description: A Deep Learning (DL) algorithm is built and tested for its ability to determine centers of star images on HST/WFPC2 exposures, in filters F555W and F814W. These archival observations hold great potential for proper-motion studies, but the undersampling in the camera's detectors presents challenges for conventional centering algorithms. Two exquisite data sets of over 600 exposures of the cluster NGC 104 in these filters are used as a testbed for training and evaluation of the DL code. Results indicate a single-measurement standard error of from 8.5 to 11 mpix, depending on detector and filter.This compares favorably to the $\sim20$ mpix achieved with the customary ``effective PSF'' centering procedure for WFPC2 images. Importantly, pixel-phase error is largely eliminated when using the DL method. The current tests are limited to the central portion of each detector; in future studies the DL code will be modified to allow for the known variation of the PSF across the detectors.

description: We present elemental abundance patterns (C, N, Mg, Si, Ca, Ti, V, Cr, Fe, Co, and Ni) for a population of 135 massive quiescent galaxies at $z\sim0.7$ with ultra-deep rest-frame optical spectroscopy drawn from the LEGA-C survey. We derive average ages and elemental abundances in four bins of stellar velocity dispersion ($σ_v$) ranging from 150$~$km$\,$s$^{-1}$ to 250$~$km$\,$s$^{-1}$ using a full-spectrum hierarchical Bayesian model. The resulting elemental abundance measurements are precise to 0.05$\,$dex. The majority of elements, as well as the total metallicity and stellar age, show a positive correlation with $σ_v$. Thus, the highest dispersion galaxies formed the earliest and are the most metal-rich. We find only mild or non-significant trends between [X/Fe] and $σ_v$, suggesting that the average star-formation timescale does not strongly depend on velocity dispersion. To first order, the abundance patterns of the $z\sim0.7$ quiescent galaxies are strikingly similar to those at $z\sim0$. However, at the lowest velocity dispersions the $z\sim0.7$ galaxies have slightly enhanced N, Mg, Ti, and Ni abundance ratios and earlier formation redshifts than their $z\sim0$ counterparts. Thus, while the higher-mass quiescent galaxy population shows little evolution, the low-mass quiescent galaxies population has grown significantly over the past six billion years. Finally, the abundance patterns of both $z\sim0$ and $z\sim0.7$ quiescent galaxies differ considerably from theoretical prediction based on a chemical evolution model, indicating that our understanding of the enrichment histories of these galaxies is still very limited.

Dilute Bose gas with correlated disorder: A Path Integral Monte Carlo study

description: We investigate the thermodynamic properties of a dilute Bose gas in a correlated random potential using exact path integral Monte Carlo methods. The study is carried out in continuous space and disorder is produced in the simulations by a 3D speckle pattern with tunable intensity and correlation length. We calculate the shift of the superfluid transition temperature due to disorder and we highlight the role of quantum localization by comparing the critical chemical potential with the classical percolation threshold. The equation of state of the gas is determined in the regime of strong disorder, where superfluidity is suppressed and the normal phase exists down to very low temperatures. We find a $T^2$ dependence of the energy in agreement with the expected behavior in the Bose glass phase. We also discuss the major role played by the disorder correlation length and we make contact with a Hartree-Fock mean-field approach that holds valid if the correlation length is very large. The density profiles are analyzed as a function of temperature and interaction strength. Effects of localization and the depletion of the order parameter are emphasized in the comparison between local condensate and total density. At very low temperature we find that the energy and the particle distribution of the gas are very well described by the T=0 Gross-Pitaevskii theory even in the regime of very strong disorder.

description: Mis on haiguste ennetamine?
Haiguste ennetamine kõlab eesti keeles ilmselt paljude arstide jaoks kontekstivälisena, sest räägib millestki, mis kuulub aega enne seda, kui patsient oma terviseprobleemiga arsti juurde jõuab. Kui haigus ennetatud, siis pole ju arsti vajagi! Selline arusaam sobib hästi hierarhilisse tervishoiusüsteemi, kus kõige all on patsient
ja tema järel aste-astmelt velsker ja jaoskonnaarst kuni tippkirurgini välja. Tänapäeval toimivad edukalt aga tervishoiusüsteemid, mis on pigem integreeritud kui
hierarhilised. Lõpptulemuse – terve inimese saavutamiseks on samavõrd olulised nii südamekirurgi, dietoloogi, perearsti kui ka perekonnaliikmete ja sageli ka sotsiaaltöötaja ning mitmete teiste oskused.

description: We investigate the extreme X-ray variability of a z = 1.608 active galactic nucleus in the 7 Ms Chandra Deep Field-South (XID 403), which showed two significant X-ray brightening events. In the first event, XID 403 brightened by a factor of $>2.5$ in $\lesssim6.1$ rest-frame days in the observed-frame 0.5-5 keV band. The event lasted for $\approx5.0\textrm{-}7.3$ days, and then XID 403 dimmed by a factor of $>6.0$ in $\lesssim6.1$ days. After $\approx1.1\textrm{-}2.5$ years in the rest frame (including long observational gaps), it brightened again with the 0.5-5 keV flux increasing by a factor of $>12.6$. The second event lasted over 251 days and the source remained bright until the end of the 7 Ms exposure. The spectrum is a steep power law (photon index $Γ=2.8\pm0.3$) without obscuration during the second outburst, and the rest-frame 2-10 keV luminosity reaches $1.5^{+0.8}_{-0.5}\times10^{43}$ erg s$^{-1}$; there is no significant spectral evolution within this epoch. The infrared-to-UV spectral energy distribution of XID 403 is dominated by the host galaxy. There is no significant optical/UV variability and $R$-band (rest-frame $\approx2500$ $\unicode{xC5}$) brightening contemporaneous with the X-ray brightening. The extreme X-ray variability is likely due to two X-ray unveiling events, where the line of sight to the corona is no longer shielded by high-density gas clumps in a small-scale dust-free absorber. XID 403 is probably a high-redshift analog of local narrow-line Seyfert 1 galaxies, and the X-ray absorber is a powerful accretion-disk wind. On the other hand, we cannot exclude the possibility that XID 403 is an unusual candidate for tidal disruption events.
