Full textAbstract:
Purpose – The purposes of this paper are to investigate the effects of integrated advertising formats on the persuasion of children, children’s awareness of the persuasive intent of these formats and how this awareness mediates the level of persuasion. Design/methodology/approach – An one-factor between-subjects experiment was conducted among 117 boys from 8 to 12 years old. Findings – This study showed that boys were more aware of the persuasive intent of a non-integrated catalog than of a brand-integrated magazine. In addition, higher awareness of the persuasive intent of the catalog enhanced persuasion in boys. Research limitations/implications – This study only focused on boys’ responses and not on girls. Practical implications – Findings imply that advertisers could focus on non-integrated print advertising formats, such as catalogs, to promote positive product attitudes among boys. Catalogs are also a more ethical way of communicating to boys because boys are generally aware of catalogs’ persuasive intent. Social implications – This study implies that even if children have sufficient persuasion knowledge, they do not necessarily use it to critically evaluate advertising. Originality/value – This paper is the first to systematically test the differences in effects of brand-integrated magazines versus catalogs targeted toward children. Importantly, it shows that persuasion knowledge plays a fundamentally different role in the persuasion process of children than of adults: awareness of the persuasive intent of catalogs increases persuasion among boys, whereas previous studies among adults showed opposite results.

Context. Developing high-precision ephemerides for Neptunian satellites requires not only the continuation of observing campaigns but also the collection and improvement of existing observations. So far, no complete catalogs of observations of Neptunian satellites are available. Aims. We aim to provide new, precise positions, and to compile a catalog including all available ground-based astrometric observations of Neptunian satellites. The observations are tabulated in a single and consistent format and given in the same timescale, the Terrestrial Time (TT), and reference system, the International Celestial Reference System (ICRS), including necessary changes and corrections. Methods. New CCD observations of Triton and Nereid were made at Lijiang 2.4-m and Yaoan 0.8-m telescopes in 2013–2019, and then reduced based on Gaia-DR2. Furthermore, a catalog called OCNS2019 (Observational Catalog of Neptunian Satellites (2019 version)) was compiled, after recognizing and correcting errors and omissions. Furthermore, in addition to what was considered for the COSS08 catalog for eight main Saturnian satellites, all observed absolute and relative coordinates were converted to the ICRS with corrections for star catalog biases with respect to Gaia-DR2. New debiasing tables for both the modern and old star catalogs, which were previously not provided based on Gaia-DR2, are developed and applied. Treatment of missing positions of comparison bodies in conversions of observed relative coordinates are proposed. Results. OCNS2019 and the new debiasing tables are publicly available online. OCNS2019 includes 24996 observed coordinates of 11 Neptunian satellites obtained over 3741 nights from 1847 to 2019. All observations are given in TT and ICRS. The star catalog biases are removed, which are significant for Nereid and outer satellites. We obtained 880 (5% of total now available) new coordinates for Triton over 41 nights (1% of total observation nights so far), and 790 (14%) for Nereid over 47 nights (10%). The dispersions of these new positions are about 0.″03 for Triton and 0.″06 for Nereid. Conclusions. OCNS2019 should be useful in improving ephemerides for the above-mentioned objects.

AbstractSince the establishment of the Hipparcos Catalog as the defining source of the optical reference frame, densification beyond its ≈ 120,000 stars has been made possible by the utilization of the Tycho-1 Catalog. The ACT, combining the old Astrographic Catalog (AC) data with the Tycho-1 positions, is the best known example of this. The Tycho-2 consortium, led by E. Høg, has performed new reductions on the Tycho data. This not only has increased the astrometric and photometric accuracies of the original 1 million Tycho-1 stars, but also has added an additional 1.5 million stars. The U.S. Naval Observatory led the effort to compute the proper motions of these 2.5 million stars. They are based not only on the AC data but also include over 140 other ground-based catalogs, all directly reduced to the Hipparcos system. The result of these efforts is the Tycho-2 Catalog, available since February 2000. Positions, proper motions, and BT and VT magnitudes are given for 2.5 million stars. The catalog is 99% complete to V=11.0, and 90% complete to V=11.5. Positional accuracies at the mean epochs vary from < 10 mas for stars V < 9 to just under 100 mas for V > 12. Proper motion accuracies are estimated to be 1.3 mas/year to 3.0 mas/year for the same magnitude ranges. Photometric accuracies range from 0.02 magnitudes for the brightest stars to 0.25 magnitudes for the faintest.

AbstractMajor advances in our understanding of the Universe have historically come from dramatic improvements in our ability to accurately measure astronomical quantities. The astrometric observations obtained by modern digital sky surveys are enabling unprecedentedly massive and robust studies of the kinematics of the Milky Way. For example, the astrometric data from the Sloan Digital Sky Survey (SDSS), together with half a century old astrometry from the Palomar Observatory Sky Survey (POSS), have enabled the construction of a catalog that includes absolute proper motions as accurate as 3 mas/year for about 20 million stars brighter than V=20, and for 80,000 spectroscopically confirmed quasars which provide exquisite error assessment. We discuss here several ongoing studies of Milky Way kinematics based on this catalog. The upcoming next-generation surveys will maintain this revolutionary progress. For example, we show using realistic simulations that the Large Synoptic Survey Telescope (LSST) will measure proper motions accurate to 1 mas/year to a limit 4 magnitude fainter than possible with SDSS and POSS catalogs, or with the Gaia survey. LSST will also obtain geometric parallaxes with accuracy similar to Gaia's at its faint end (0.3 mas at V=20), and extend them to V=24 with an accuracy of 3 mas. We discuss the impact that these LSST measurements will have on studies of the Milky Way kinematics, and potential synergies with the Gaia survey.

AbstractThe SUPERBLINK survey catalogs all stars brighter than R = 19 mag and with proper motions larger than 40 mas yr−1, down to a declination of −33○. The catalog inevitably includes a significant fraction of the presumed low-mass members of several nearby young moving groups (Beta Pic, AB Dor, Tuc-Hor, Argus), or low-mass escapees from the Hyades and Pleiades clusters. We discuss opportunities and challenges in identifying the missing M dwarf members of these moving groups. While rounding up the majority of the potential M dwarf members of these groups, such samples are significantly affected by co-moving field stars, both young and old, due to the heavy clumping of the local field population in velocity space.

AbstractThe mid-infrared provides a unique view of galaxy stellar populations, sensitive to both the integrated light of old, low-mass stars and to individual dusty mass-losing stars. We present results from an extended Spitzer/IRAC survey of M31 with total lengths of 6.6 and 4.4 degrees along the major and minor axes, respectively. The integrated surface brightness profile proves to be surprisingly difficult to trace in the outskirts of the galaxy, but we can also investigate the disk/halo transition via a star count profile, with careful correction for foreground and background contamination. Our point-source catalog allows us to report on mid-infrared properties of individual objects in the outskirts of M31, via cross-correlation with PAndAS, WISE, and other catalogs.

For more than 50 years, the continuous photographic observations of asteroids have been carried outwith telescopes of the Astronomical Observatory of the Taras Shevchenko National University of Kyiv and the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. About 3,000 photographic plates were obtained, some of which were exposed in 1908. We collected the data on more than 5,500 positions and magnitudes of asteroids on these astroplates taking into account all results of the processing of observations available in various publications and in the Minor Planet Center database. All positional data were compared with JPL ephemeris and analyzed. From different series of asteroid observations the values of positional accuracy were obtained, depending on the methods of measuring and processing the plates and reference catalogs of stars. In order to systematically improve the obtained asteroid positions, we evaluated the possibilities of reprocessing some of the earliest asteroid observations applying the modern star high accuracy catalogs. Using the Tycho-2, Gaia DR2, and Gaia EDR3 as the reference catalogs, the 590 astroplates exposed on the MAO NASU Double Long-Focus Astrograph (DLA) in 1952-1986 were reprocessed based on old plate measurements. All newly determined and previous original asteroid positions were compared with the JPL ephemeris. The comparison results show an improvement in the systematic and random components of the accuracy of coordinates for new positions of asteroids. When comparing the new positions of the asteroids determined in the Tycho-2 and Gaia catalog systems, no significant changes in accuracy were found.

The average undergraduate horticulture major at the Univ. of Florida Academic Program at Fort Lauderdale is 38 years old. The older, non-traditional student population is quite diverse, but many individuals are motivated by a desire to change careers, and many of them have taken extensive academic course work at other institutions prior to applying for admission to the Univ. of Florida. Academic advisement of this type of student presents a substantial challenge because of the uncertainty of content and vigor of prior academic preparation. To help meet this challenge, we have developed several academic advisement checklists that indicate numbers and titles of critical preprofessional and general education courses from the academic institutions that have been most frequently attended by the highest numbers of the incoming non-traditional students. These checklists have been cross-referenced between the catalogs of the various academic institutions and the Univ. of Florida catalog. We use these documents to evaluate the academic preparation of incoming transfer students and to assist them in making correct course selections to remedy any academic deficiencies that could negatively influence their success in upper division horticulture course work.

Aims. We plan to identify the members of the Bochum 7 association by performing simultaneous astrometric and spectrophotometric analyses, and estimate its distance and evolutionary stage. Methods. We used our own visual spectroscopic and UBV photometric data of a 30′ × 30′ region centered at = 8h44m47.2s, = −45°58′55.5″. This information enabled us to estimate the spectral classification and distance of all stars present in the region. The proper motion was analyzed with data of the UCAC 5 catalog and was used to identify the members of this association. We added JHK data from 2MASS and IRAS catalogs to check for the presence of infrared (IR) excess stars. Results. We found that Bochum 7 is an OB association with at least 27 identified stellar members (l = 265°.12, b = − 2°) at a distance of ≃5640 pc. Its proper motion is μαcos δ = −4.92 ± 0.08 mas yr−1, μδ = 3.26 ± 0.08 mas yr−1. We derived an average heliocentric radial velocity of ~35 km s−1 and were able to confirm the binary nature of the (ALS 1135) system and detect four new binary star candidates. Analysis of data for massive Bo 7 star candidates points towards a young age (≤ 3 × 106 years old) for the association, although the presence of a previous episode of star formation remains to be analyzed.

This sketch concerns the notions of groups that were considered aliens by the old Poles. Methodologically the work remains in the circle of ethnolinguistic research. The analysis uses the tools developed by the theory of linguistic image of the world. Material has been excerpted from 4 catalogs of rulers created in the period from the seventeenth to the eighteenth century. In the observed catalogs, there are three points of view, from the perspective of which the alien is categorized; these are the optics of a sword, cross, crown. The reconstruction of the infidels’ image in the article is carried out in the context of the functions this category plays in the era of shaping and preservation of national identity in a multi-ethnic and multi-religious country.

AbstractThe TOCAMM (TOrino CAgliari Measuring Machine) project undertaken jointly between Torino and Cagliari Astronomical Observatories aimed to convert the old measuring machine ASCORECORD into an automatic and impersonal one. This program is intended to contribute to the link of the HIPPARCOS Catalogue to the ICRS through the determination of precise position of optical counterparts of 80 extragalactic radiosources taken from the IERS list and to investigate the astrometric accuracy of the Guide Star Catalog (version 1 and 2). The calibration test phase, carried out first at the Astronomical Observatory of Torino and after at Cagliari Observatory, where the machine has been now installed, indicate that the available positional accuracy is about 0.5 microns in both x and y coordinates.

Full textAbstract:
Context. Carte du Ciel was a global international project at the end of the nineteenth and beginning of the twentieth century to map the sky to about magnitude 14 on photographic plates. The full project was never observationally completed and a large fraction of the observations made remain unanalyzed. Aims. We want to study whether the astrometric and photometric accuracies obtained for the Carte du Ciel plates digitized with a commercial digital camera are high enough for scientific exploitation of the plates. Methods. We use a digital camera Canon EOS 5Ds, with a 100 mm macrolens for digitizing. We analyze six single-exposure plates and four triple-exposure plates from the Helsinki zone of Carte du Ciel (+39∘ ≤ δ ≤ +47∘). Each plate is digitized using four images, with a significant central area being covered twice for quality control purposes. The astrometric calibration of the digitized images is done with the data from the Tycho-Gaia Astrometric Solution (Gaia TGAS) of the first Gaia data release (Gaia DR1), Tycho-2, Hot Stuff for One Year (HSOY), USNO CCD Astrograph Catalog (UCAC5), and PMA catalogs. Results. The best astrometric accuracy is obtained with the UCAC5 reference stars. The astrometric accuracy for single-exposure plates is σ(α cos(δ)) = 0.16″ and σ(δ)=0.15″, expressed as a Gaussian deviation of the astrometric residuals. For triple-exposure plates the astrometric accuracy is σ(α cos(δ)) = 0.12″ and σ(δ)=0.13″. The 1 − σ uncertainty of photometric calibration is about 0.28 mag and 0.24 mag for single- and triple-exposure plates, respectively. We detect the photographic adjacency (Kostinsky) effect in the triple-exposure plates. Conclusions. We show that accuracies at least of the level of scanning machines can be achieved with a digital camera, without any corrections for possible distortions caused by our instrumental setup. This method can be used to rapidly and inexpensively digitize and calibrate old photographic plates enabling their scientific exploitation.

Full textAbstract:
Aims. Questions of how massive quiescent galaxies rapidly assembled and how abundant they are at high redshift are increasingly important in the study of galaxy formation. Looking at these systems can shed light on the processes of galaxy mass assembly and quenching of the star formation at early epochs. In order to address these questions, we aim to identify and characterize massive quiescent galaxies from z ∼ 2.5 out to the highest redshifts at which these systems can be found. The final purpose is to compare the results with the predictions of state-of-the-art semi-analytical models of galaxy formation and evolution. Methods. We defined observer-frame color–color diagrams to optimally select quiescent galaxies at z > 2.5 and applied them to the COSMOS2015 catalog. We refined the spectral energy distribution (SED) fitting analysis for the selected candidates to confirm their quiescent nature, then derived their number density, mass density, and stellar mass functions. Finally, we compared the results with previous observations and some current semi-analytic models. Results. We selected candidates for quiescent galaxies in the redshift range 2.5 ≲ z ≲ 4.5 from the COSMOS2015 catalog by means of two color–color diagrams. The additional SED fitting analysis allowed us to select 128 galaxies, consistent with being massive (log(M*/M⊙)≥10.6), old (ages ≳0.5 Gyr), and quiescent (log(sSFR [yr−1]) ≤ −10.5) objects at high redshift (2.5 < z < 4.5). Their number and mass densities are in fair agreement with previous observations and, if confirmed, show a discrepancy with current semi-analytical models of galaxy formation and evolution, that underpredict the number of massive quiescent systems up to a factor of ∼12 at 2.5 ≤ z < 3.0 and ∼10 at z ∼ 4.0. The evolution of the stellar mass functions (SMFs) of these systems is similar to previous estimates and indicates a disagreement with models, particularly with regard to the shape of the SMF. Conclusions. The present results add further evidence to the possibility that massive and quiescent galaxies can exist out to at least z ∼ 4. If future spectroscopic observations carried out with, for example, the James Webb Space Telecope (JWST), confirm the substantial presence of such a population, further work on modeling the stellar mass assembly, as well as supermassive black hole accretion and feedback processes at early cosmic epochs, is needed to understand how these systems formed, evolved, and quenched their star formation.

The metallicity-sensitive (U – G) colors from the new homogeneous catalog of photographic RGU data in seven high-latitude fields have been used to determine the larger-scale metallicity distributions of the Galactic population components. For the thick disk, preliminary analysis based on our best structural models provides a mean metallicity 〈[M/H]〉 = −0.6 ± 0.3dex and a marginal vertical metallicity gradient ≈ −0.1dex/kpc. The observed color distributions are further consistent with the (old) thin disk having mean abundance 〈[M/H]〉 = −0.3 ± 0.2dex and abundance gradient ∂[M/H]/∂z = −0.6dex/kpc.

Full textAbstract:
Context. The dispersal of protoplanetary disks sets the timescale that is available for planets to assemble, and thus it is one of the fundamental parameters in theories of planetary formation. Disk dispersal is determined by several properties of the central star, the disk itself, and the surrounding environment. In particular, the metallicity of disks may affect their evolution, but controversial results have been published so far: disks in low-metallicity clusters appear to disperse rapidly, while some evidence supports the existence of accreting disks that are several million years old in the Magellanic Clouds. Aims. We study the dispersal timescale of disks in Dolidze 25, the young cluster in the proximity of the Sun with the lowest metallicity, to understand whether disk evolution is affected by the low metallicity of the cluster. Methods. We analyzed Chandra ACIS-I observations of the cluster and combined the resulting source catalog with existing optical and infrared catalogs of the region. We selected the disk-bearing population in a circular region with a diameter of 1° centered on Dolidze 25 from criteria based on infrared colors, and we selected the disk-less population within a smaller central region from the X-ray sources with O infrared counterparts. In both cases, criteria were applied to discard contaminating sources in the foreground or background. We derived stellar parameters from isochrones that were fit to color-magnitude diagrams. Results. We derived a disk fraction of ∼34% and a median age of the cluster of 1.2 Myr. To minimize the effect of incompleteness and spatial inhomogeneity in the list of members, we restricted this calculation to stars in a magnitude range within which our selection of cluster members is fairly complete. We also adopted different cuts in stellar masses. When we compare this estimate with existing estimates of the disk fraction of clusters younger than 10 Myr, the disk fraction of Dolidze 25 appears to be lower than what is expected based on its age alone. Conclusions. Even though our results are not conclusive given the intrinsic uncertainty on stellar ages estimated from isochrone fitting to color-magnitude diagrams, we suggest that disk evolution in Dolidze 25 may be affected by the environment. Given the poor O-star population and low stellar density of the cluster, it is more likely that the disk dispersal timescale is dictated more by the low metallicity of the cluster than by external photoevaporation or dynamical encounters.

Full textAbstract:
The paper focuses on the episode of the formation of Ivan Franko’s library. Franko was actively interested in books all his life, and his collection was a mobile organism: he followed the new editions, ordered catalogs from everywhere, and generously shared his books. The unique library has survived to this day as part of the writer’s archival collection. Both modern editions and old prints (which are rather numerous) retain evidence of their movements. Gift inscriptions, bookplates, stamps of institutions and organizations, notes and marks on the margins — all these pieces of evidence complement the information about Franko’s circle of communication and creative interests, being an important source for studying his biography. It is impossible to completely reconstruct the history of acquiring the books that form this memorial collection, but a number of facts give grounds for some conclusions on this issue. Franko’s unexpected visit to Kyiv in 1909 is described in many memoirs, but only D. Doroshenko, who accompanied the writer to the bookstores, briefly told what publications his companion was interested in, and which booksellers he met, naming several particular places they visited. The traces of these locations in the books from the collection may serve as proof that the writer brought them from his trip. Now working with Franko’s personal library, the author of the paper is trying to find out which books from Kyiv enriched Franko’s collection. The testimonies by D. Doroshenko, bookplates, ownership inscriptions and stamps, numbers of books assigned by the owner of the library, and other data were taken into account. Many editions of this collection have stamps or stickers of booksellers from different cities and countries, including those that Franko never visited. The writer’s archive also contains book advertisements and catalogs, as well as his correspondence with publishers and second-hand booksellers. Thus, generally linking the collection of Ivan Franko’s library to his travels proves to be not a very productive task.

AbstractAbout 40% of potential OH / IR stars, color selected from the IRAS Point Source Catalog, have no 1612 MHz masers. While these objects are rarely carbon rich, they are usually associated with circumstellar shells. The natural explanation for these “OH / IR star color mimics” is that they are systems with a degenerate companion collecting an accretion disk from a red giant wind. This provides them with an extra source of UV for dissociating their molecules. The persistent absence of the usual complement of masers from an O-rich shell is then a pointer to the presence of a degenerate companion. These occur in association with ~45% of old giant stars.

AbstractModern tasks of high precision astrometry demand optical coordinate systems including more faint stars than are available now in current conventional systems (Hipparcos). For this purpose it is suggested to use old photographic observations accumulated in the Pulkovo Observatory. Extensive observational data have been obtained at Pulkovo Observatory during the last century in the framework of several programs, e.g. Pulkovo Galaxy plan, etc. Observations have been made with the Normal Astrograph from 1894 to the present. The data are investigated with the aim of extending the Hipparcos catalog to stars fainter than 11th magnitude. All available observations are taken into account. A description of the material considered is given. The distribution of the selected plates over the celestial sphere is shown as well. Coordinates of faint stars in the Hipparcos system are calculated for selected areas. The accuracy of computed star coordinates is analyzed. Results of the investigation are presented.

The paper describes the stages of studying the biochemical heterogeneity of gluten proteins of wheat grain as an important factor in the baking quality of flour. It has been shown that the biochemical heterogeneity of gluten proteins is caused by genetic factors. Modern electrophoretic methods on gel carriers make it possible to study the component protein composition of varieties, biotypes, lines, split hybrids and to identify the Mendelian units of the spectrum (genes, alleles). The application of the idea of the genetic nomenclature of the hereditary unit of gliadins (a block of components) is over 40 years old, and it was proposed by domestic scientists (Kopus, Poperelya, Sozinov). This made it possible to compile catalogs of blocks of components (alleles), to study their correlation with quality, frost resistance and other traits, to develop a scale for combining gliadin blocks in the spectrum of varieties for the breeding assessment of samples from agro-nurseries. It has been established that electrophoregrams of prolamins serve as a reliable criterion to identify seed genotypes of commercial varieties by laboratory methods.

The sei whale (Balaenoptera borealis) was intensively exploited throughout its range, with about 110.000 individuals hunted by pelagic fleets in Antarctic waters between 1960 and 1970. In addition, basic information on its distribution, migratory routes, and feeding grounds in the southeastern Pacific, has been poorly documented. In the case of Chile, recent information consists mainly of accidental records. This research presents the first sei whale photo-identification catalog for south-central Chile. From November 2019 to January 2020, 88 individuals were recorded from land-based and boat surveys at Caleta Chome. Of these, 12 individuals were photo-identified through scars or distinctive notches in the dorsal fins. The peak of sightings occurred during December 2019; two individuals were sighted on more than one occasion.

Context. In Gaia DR2, an unprecedented high level of precision has been reached at sub-milliarcsecond for astrometry and millimagnitudes for photometry. Using cluster members identified with the astrometry and photometry in Gaia DR2, we can obtain a reliable determination of cluster properties. However, because of the shortcomings of Gaia spectroscopic observations in dealing with densely crowded cluster regions, the RVs and metallicity values for cluster member stars from Gaia DR2 are still lacking. It is necessary to combine the Gaia data with the data from large spectroscopic surveys, such as LAMOST, APOGEE, GALAH, and Gaia-ESO. Aims. In this study our aim is to improve the cluster properties by combining the LAMOST spectra. In particular, we provide the list of cluster members with spectroscopic parameters as an add-value catalog in LAMOST DR5, which can be used to perform a detailed study for a better understanding of the stellar properties, by using their spectra and fundamental properties from the host cluster. Methods. We cross-matched the spectroscopic catalog in LAMOST DR5 with the identified cluster members in Cantat-Gaudin et al. (2018, A&A, 618, A93). We then used members with spectroscopic parameters to derive statistical properties of open clusters. Results. We obtained a list of 8811 members with spectroscopic parameters and a catalog of 295 cluster properties. The provided cluster properties include astrometric parameters, spectroscopic parameters, derived kinematic and orbital parameters, and isochrone fitting results. In addition, we study the radial and vertical metallicity gradient and age-metallicity relation with the compiled open clusters as tracers, finding slopes of −0.053 ± 0.004 dex kpc−1, −0.252 ± 0.039 dex kpc−1, and 0.022 ± 0.008 dex Gyr−1, respectively. The slopes of the metallicity distribution relation for young clusters (0.1 Gyr < Age < 2 Gyr) and the age-metallicity relation for clusters within 6 Gyr are both consistent with the literature results. In order to fully study the chemical evolution history in the disk, more spectroscopic observations for old and distant open clusters are needed for further investigation.

The genus Solenysa Simon, 1894 belongs to Linyphiidae Blackwall, 1859, which is a species-rich group, including 608 genera and 4,571 species (World Spider Catalog 2018). Solenysa currently includes 14 species from China, Japan and the Korean Peninsula (Simon 1894; Namkung 1986; Li & Song 1992; Gao, Zhu & Sha 1993; Tu, Ono & Li 2007; Ono 2011; Tu & Hormiga 2011; Wang, Ono & Tu 2015). The linyphiid phylogeny based on molecular data shows that Solenysa species forms one of the seven main clades within Linyphiidae (Wang et al. 2015). According to the phylogenetic analysis based on morphological data, Tu and Hormiga (2011) divided the genus Solenysa into four species groups, each having a unique genital type comprised by series genital characters. As an old branch with a long evolutionary history, Solenysa spiders have accumulated a long list of synapomorphies (Tu & Hormiga 2011), not only having a unique somatic appearance, but also specific genitalic characters that distinguish them from all other linyphiids.

Abstract Using the cross-matched data of Gaia EDR3 and the Two Micron All Sky Survey Point Source Catalog, a sample of RC stars with parallax accuracies better than 20% is identified and used to reveal the nearby spiral pattern traced by old stars. As shown in the overdensity distribution of RC stars, there is an arc-like feature extending from l ∼ 90° to ∼243°, which passes close to the Sun. This feature is probably an arm segment traced by old stars, indicating the galaxy potential in the vicinity of the Sun. With a comparison to the spiral arms depicted by young objects, we found that there are considerable offsets between the two different components of the Galactic spiral arms. The spiral arm traced by RC stars tends to have a larger pitch angle, and hence a more loosely wound pattern.

Astrometry is the oldest of the astronomical endeavors. Indeed, we still have the observing journals of Galileo, the journals of Flamsteed, and those of most of the other old transit-circle astronomers. We have most of the early photographic plates taken for the astrographic catalog project, and almost all the parallax plates. However, as technology progressed, we have become somewhat less precise in recording what we did. It is for this reason that this joint meeting was called: to impress on the modern astronomer that, in general, he only extracts a fraction of the information from his observations, and that these observational data may, in the future, provide an invaluable source needed for the progress of the science.

Anders Toftgaard: Mapping a collection. What the catalogue records can tell us about Otto Thott’s manuscript collection and about manuscript cataloguing.
This article deals with the manuscript collection of Count Otto Thott (1703-1785) and with manuscript cataloguing. Otto Thott was the single greatest private book collector in the history of Denmark and of inestimable importance for the Royal Danish Library, since he bequeathed his collection of manuscripts (4154 catalogue numbers) and books printed before 1531 (6059 catalogue numbers) to the Royal Library. In the manuscript collection, the inclusion of his collection marks the division between the Old Royal Collection (GKS) and the New Royal Collection (NKS). Many of the treasures in the rare books collection come from his library, and his definition of paleotypes (books printed before 1531) has (in the 20th c.) determined the definition of the collection of post-incunabula. Otto Thott did not write owners’ marks or notes in his books and he left very little archival material concerning the ways in which he created his library. Regrettably, the literary correspondence mentioned in his will has not survived. The article analyses a data set consisting of all catalogue records (in MARC format) concerning manuscripts from Otto Thott’s manuscript collection. These catalogue records in the library system derive from the catalogue made by Rasmus Nyerup (excluding oriental manuscripts) and published in 1795. When, towards the end of the 19th centrury, the alphabetical and the systematical catalogues of the collection of western manuscripts were produced, the entries in Nyerup’s catalogue were copied by hand without being revised. After the IT revolution, when the catalogue records of the systematical catalogue were transferred to a digital database of records, these records were copied once again without revision. It is shown what kind of errors from the catalogue of 1795 were still present in the on line catalogue in 2019. The quantitative analysis shows that the bulk of the manuscripts in Thott’s manuscript collection are manuscripts in Danish and German from Thott’s own century. The subject headings with most entries are Theology, History, History of Denmark, Danish Biography and Literature. As to provenances there is information concerning the manuscript’s provenance before the inclusion in Otto Thoot’s library in 17 % of the catalogue records. The analysis shows that Otto Thott’s manuscript collection was a universal collection with no specific preferences. The conclusion argues that it is necessary to get information from the various printed catalogs of the manuscript collection into the digital library system and that parts of Thott’s manuscript collection deserve revisiting and recataloguing. The Royal Danish Library’s manuscript collection might explore alternatives to the MARC-format for manuscript cataloguing. In a wider context, it is argued that Otto Thott’s library should be considered a knot in a network, and that data from the many book auction catalogues should be extracted and used for mapping the destinies of specific books and manuscripts.

Continues magnetic measurements at the IKIR FEB RAS obser-vatories Magadan (MGD), Paratunka (PET), Yuzhno-Sakhalinsk (YSS), Cape Schmidt (CPS) and Khabarovsk (KHB) and CSIR-NGRI observatories Hyder-abad (HYB) and Choutuppal (CPL) have been started almost since their formation. A significant part of the results obtained is presented in the WDC and INTERMAGNET databases. However, a large amount of raw data remains un-processed and unavailable for using by scientific community. In the past few years, institutes has been making efforts to process and reprocess old magnetic data. Digital images of analog magnetograms of the Observatory Paratunka since 1967 were obtained and the possibility of their use for calculation hourly and minute values of magnetic field elements was evaluated. Old digital data that was available during the conversion from analog to digital magnetometers is processed. The main problem of processing or re-processing archived data is the lack of information (metadata) about the measurement conditions. First of all, these are the results of absolute observations, which are necessary to obtain the values of the elements of the total field vector. In this paper, some technologies are proposed that allow to use the data obtained during processing of analog magnetograms to adjust the digital magnetometers records. A signif-icant problem is the lack or inaccuracy of information about the temperature conditions in the variation pavilion, about magnetometers or support equipment maintenance or about works in and near the pavilions. As we accumulate the experience during the processing of old magnetic data, a “catalog” of noise and its typical images is formed. This makes it more reliable and efficient to identify and remove this noise from records.

Full textAbstract:
This essay aims to analyze the ways in which László Moholy-Nagy’s concepts of “new typography” and “typophoto” were essential to the creation of a new typology of publications: visual books, which have a strong image component, resulting from the popularization of photography and cinema. New typography was defined in 1923 by László Moholy-Nagy in a short text for the catalog of the Bauhaus exhibition Staatliches Bauhaus in Weimar 1919–1923. New typography resulted from a new graphical orientation by Bauhaus, influenced by the ideology of several avant-garde movements, such as De Stijl and Russian Constructivism, that celebrated simplification, geometrization and the advantages of modern technology to construct a visual language that could communicate clearly and in a universal manner. In Moholy-Nagy’s text, new typography called for an analysis of the relation between form and content through the collapsing of the “classic model” (the “old typography”) and the objective use of photography. In 1925, Moholy-Nagy introduced the notion of typophoto in Painting, Photography, Film to realize the “bioscopic book” of El Lissitzky, which is more visual than textual. In publications like the exhibition catalog Staatliches Bauhaus in Weimar 1919–1923 or the Bauhausbücher series, Moholy-Nagy puts both principles into practice, converting the book into a space of visual exploration, endowed with a cinematic dimension that comes close to his notion of “vision in motion”. Through the use of a qualitative research methodology, and based on a critical review of literature and the direct observation of case studies, this essay aims to show how Moholy-Nagy’s multidisciplinary legacy contributed to a paradigm shift in book design.

Though he was only 45 years old at the time of his death, he personally authored over 100 books and articles, and made over thirty contributions (e.g., chapters, articles, prologues) to the books of other people from around the world. His own interests were varied, but centered mostly on mission, evangelism, and Latin America. This bibliography is an attempt to collect and record his writings, all in one place. It is offered as a tribute to his life and ministry. Wherever possible, searching aids have been included. Examples are the Library of Congress cataloguing numbers (for most of the books) and the Reigner Recording Library Catalog numbers (for the sound recordings at the Union Theological Seminary, Richmond, Virginia).

It is well known that the velocity dispersions of the stars in the solar neighbourhood increase with their ages (Wielen 1977). In Fig.1 we show |W| weighted velocity dispersions (cf. Wielen 1977) of the stars in the Third Catalog of Nearby Stars (Gliese and Jahreiß 1994). Open symbols indicate main sequence stars and crosses indicate McCormick stars, a kinematically unbiased subset of the CNS3, respectively, whereas the filled symbols are the Edvardsson et al. (1993) data. Stars older than 14 Gyr are not shown because they are probably thick disk stars (Freeman 1991). We have assumed a maximum age of the old thin disk stars of 12 Gyr as suggested by the Edvardsson et al. data. As can be seen from Fig.1 both data sets fit ideally together. The solid line indicates a σ ∝ τ1/2 law.

AbstractComparison of galaxy flows with those predicted from the local galaxy distribution ended as an active field after two analyses came to vastly different conclusions 25 years ago, but that was due to faulty data. All the old results are therefore suspect. With new data collected in the last several years, the problem deserves another look. The goal is to explain the 640 km/s dipole anisotropy of the CMBR. For this we analyze the gravity field inferred from the enormous data set derived from the 2MASS collection of galaxies (Huchra et al. 2005), and compare it to the velocity field derived from the well calibrated SFI++ Tully-Fisher catalog (Springob et al. 2007). Using the “Inverse Method” to minimize Malmquist biases, within 10,000 km/s the gravity field is seen to predict the velocity field (Davis et al. 2011) to remarkable consistency. This is a beautiful demonstration of linear perturbation theory and is fully consistent with standard values of the cosmological variables.

AbstractRR Lyrae variables are powerful tools to study their host stellar populations. Globular clusters and dwarf galaxies are old and usually host this type of variables. With a growing number of low luminosity objects discovered in the halo of the Milky Way, classifying stars clusters and galaxies has become more challenging. In this study, we examine the properties of RR Lyrae stars in globular clusters and dwarf galaxies in the Local Group. We construct a catalog of RR Lyrae variables in the Local Group globular clusters and dwarf galaxies from previously published data and compare the properties of RR Lyrae variables between those two types of stellar systems. Our goal is to search for a physical difference in the properties of RR Lyrae variables in those two classes of stellar systems. We also analyze the global trend of RRLs in these systems to understand more about their formation and evolution history.

The article is devoted to Cyrillic handwritten books of the XIII–XIX centuries, created in the Romanian principalities, and stored today in the manuscript collections of the Russian State Library. The uniqueness of the writing system, functioning in the principalities (Wallachia, Moldavia, Transylvania) since their political formation, is that it was a Cyrillic script based on the old Slavic language with a predominant Roman-speaking population. In course of the writing system’ development in the principalities, there was a transition from the Slavic font to the Latin one; the intermediate result of this transition was the creation of monuments written in Romanian language with Cyrillic script. The main stages of this process are considered by reference to the specific examples of unique handwritten books and their fragments that have become objects for collecting by scientists, antiquaries, and Old Believers, whose book collections have formed the basis of the handwritten collections of the Russian State Library. They are the oldest Cyrillic manuscripts and their fragments dated to the XII–XIV centuries, found on the territory of Romania, Slavic manuscripts, produced mainly in monasteries of principalities in the XV–XVII centuries, translations of individual words into the Romanian language in the rewritten Slavic texts in the XVI century; the glosses and comments in Romanian on the margins of Slavic manuscripts in the XVI–XVIII centuries; numerous notes in the Romanian language in the manuscripts of the XVI–XVIII centuries, made by owners and readers; translations of literary monuments, including bilingual (Slavic–Romanian) and trilingual (Slavic–Latin–Romanian) versions in the XVI–XVIII centuries; Romanian–Slavic and Slavic–Romanian dictionaries in the XVII–XVIII centuries; letters and their copies in the Romanian language (sureties) in the XVI–XIX centuries. The article is an intermediate outcome of studying and describing Cyrillic Romanian handwritten books in the collections of the Russian State Library, which will result in the publication of a hard–copy catalog.

Using parallaxes and proper motions of a kinematically and spatially unbiased sample of old bright red giant stars from the Hipparcos catalog with measured radial velocities from Barbier-Brossat & Figon (2000), we have re-estimated the surface density of the Galactic disk in the solar neighbourhood within ±0.4 kpc of the Sun. We determine the vertical distribution of the red giants as well as the vertical velocity dispersion of the sample, (14.4±0.26 km/sec), and combine these to derive the surface density of gravitating matter in the Galactic disk. Using these data, we determine the surface density of the galactic disk as a function of the galactic coordinate, z. the surface density of the disk increases from 10.5 ±0.5 M⊙within ±50 pc to 42 ±6 M⊙/pc2 within ±350 pc. The volume density of the galactic disk within ±50 pc is 0.105±0.005 M⊙/pc3, which is only marginally greater (within 2 sigma) than the volume density estimates of observed baryonic matter in the solar neighbourhood.

Data at the time of making the giant skeleton given in the catalog of the fundamental museum and literary sources of the 19th century were quite different and refer to the period from 1814 to 1818. Probably, the giants corpse was taken to the Department of Anatomy and Physiology of the Imperial MedicalSurgical Academy to establish the cause of death. After a while, the skeleton was presented to the Academy Conference as a rare museum exhibit and presented to its president, Jacov Willie, who returned the skeleton to the department. From 1818 to 1824, the skeleton temporarily left the walls of the academy and was examined by I.V. Buyalsky in the home museum. After the scientific work, the skeleton was returned to the department; as a result of the research conducted by I.V. Buyalsky in 1847, the article Measure of the skeleton and the weight of the bones of the giant Jacob Lolly, was the only published scientific work on the skeleton of a giant. The measurements were translated into the modern system of units. A brief description of the giants skull as a vivid example of typical changes in acromegaly was made a hundred years later by A.P. Bystrov, an employee of the department, in the book, Past, present, future of man. Two hundred years after its construction, the giants skeleton needed restoration, including delicate cleaning, restoration of destroyed fragments, and replacement of the material to imitate the cartilaginous components of the skeleton. The restorers work process is described, and the result of their activity is presented.

Aims. The supernova remnant (SNR) G150.3+4.5 was recently discovered in the radio band; it exhibits a shell-like morphology with an angular size of ~ 3°, suggesting either an old or a nearby SNR. Extended γ-ray emission spatially coincident with the SNR was reported in the Fermi Galactic Extended Source Catalog, with a power-law spectral index of Γ = 1.91 ± 0.09. Studying particle acceleration in SNRs through their γ-ray emission is of primary concern to assess the nature of accelerated particles and the maximum energy they can reach. Methods. Using more than ten years of Fermi-LAT data, we investigate the morphological and spectral properties of the SNR G150.3+4.5 from 300 MeV to 3 TeV. We use the latest releases of the Fermi-LAT catalog, the instrument response functions and the Galactic and isotropic diffuse emissions. We use ROSAT all-sky survey data to assess any thermal and nonthermal X-ray emission, and we derive minimum and maximum distance to G150.3+4.5. Results. We describe the γ-ray emission of G150.3+4.5 by an extended component which is found to be spatially coincident with the radio SNR. The spectrum is hard and the detection of photons up to hundreds of GeV points towards an emission from a dynamically young SNR. The lack of X-ray emission gives a tight constraint on the ambient density n0 ≤ 3.6 × 10−3 cm−3. Since G150.3+4.5 is not reported as a historical SNR, we impose a lower limit on its age of t = 1 kyr. We estimate its distance to be between 0.7 and 4.5 kpc. We find that G150.3+4.5 is spectrally similar to other dynamically young and shell-type SNRs, such as RX J1713.7−3946 or Vela Junior. The broadband nonthermal emission is explained with a leptonic scenario, implying a downstream magnetic field of B = 5 μG and acceleration of particles up to few TeV energies.

Abstract We present accurate and deep multiband (g, r, i) photometry of the Local Group dwarf irregular galaxy NGC 6822. The images were collected with wide-field cameras at 2 m/4 m (INT, CTIO, CFHT) and 8 m class telescopes (Subaru) covering a 2 deg2 field of view across the center of the galaxy. We performed point-spread function photometry of ≈7000 CCD images, and the final catalog includes more than 1 million objects. We developed a new approach to identify candidate field and galaxy stars and performed a new estimate of the galaxy center by using old stellar tracers, finding that it differs by 1.′15 (R.A.) and 1.′53 (decl.) from previous estimates. We also found that young (main sequence, red supergiants), intermediate (red clump, asymptotic giant branch (AGB)), and old (red giant branch) stars display different radial distributions. The old stellar population is spherically distributed and extends to radial distances larger than previously estimated (∼1°). The young population shows a well-defined bar and a disk-like distribution, as suggested by radio measurements, that is off-center compared with the old population. We discuss pros and cons of the different diagnostics adopted to identify AGB stars and develop new ones based on optical–near-IR–mid-IR color–color diagrams to characterize oxygen- and carbon-rich stars. We found a mean population ratio between carbon and M-type (C/M) stars of 0.67 ± 0.08 (optical/near-IR/mid-IR), and we used the observed C/M ratio with empirical C/M–metallicity relations to estimate a mean iron abundance of [Fe/H] ∼ −1.25 (σ = 0.04 dex), which agrees quite well with literature estimates.

Abstract. Series of major earthquakes struck the Sundaland plate as a result of convergence with neighboring plates such as Indian, Australian and Philippine plates. Since then, the Sundaland is experiencing significant crustal deformation that implicate reactivation of local fault and embark question on the status of geohazard and seismic risk. In Malaysia, crustal deformation study by using Global Positioning System (GPS) has been conducted for many years. However, the information of crustal deformation was reported separately and difficult to be archived. In addition, continuous estimation of crustal deformation derived from GPS has to be carried out in order to provide present day seismic status. This study aims at generating a seismic catalog map in Malaysia derived from approximately nine (9) years of GPS data. In this study, derived long-term crustal deformation in the form of coordinate time series (CTS) were converted into yearly strain map. The changes of strain with respect to location of old and active fault line in Malaysia were properly analysed. From the result, the highest changes of strain rate for Peninsular Malaysia happened in 2004 until 2005 and 2012 until 2013 prior to 2004 Acheh earthquake event with the moment magnitude (Mw) and 2012 two strike-slip events in Northern Sumatera with the magnitude of 8.2Mw and 8.6Mw. In North Borneo region, the most significant changes of strain rate happened from 2007 to 2009 and 2011 to 2013. It can be expected that the results will be beneficial in augmenting geohazard mitigation in Malaysia.

"Interns and Volunteers Crucial in Curating and Digitizing Fossil Invertebrates in the Field Museum’s Fast Growing Mazon Creek Collection." Biodiversity Information Science and Standards 2 (June 13, 2018): e25942. http://dx.doi.org/10.3897/biss.2.25942.
Full textAbstract:
The Mazon Creek region in Northeastern Illinois is home to a Middle Pennsylvanian (~307 million years old) soft-bodied fossil Lagerstätte of animals and plants that lived along a subtropical swampy coastline. This area was strip mined for coal from 1928 to 1974 and museum geologists and amateur collectors acquired large fossil collections during this time by collecting and splitting millions of nodules unearthed at the mines. These large collections are important because of the rarity of many of the species in the Mazon Creek biota. There are about 250 described fossil invertebrate species from the Mazon Creek region. Fifty-one of these species (mostly insects and arachnids) are represented by just a single specimen in the Field Museum’s collection. Since the 1980’s collecting has decreased and the mines have been restored to parks and wildlife areas. The Field Museum maintained a collection of 34,000 Mazon Creek invertebrate fossil for many decades. With the new donations from private collectors in the last three years this collection has grown by 20% and now represents 18% of the Fossil Invertebrate systematic collection. The Mazon Creek is also the most used fossil invertebrate collection accounting for about 38% of loans in the last five years. Dealing with these large and often unexpected donations adds to the already large workload of the collection staff, so interns and volunteers are utilized to process, catalog, digitize, and integrate these fossils into the museum’s collection. In the summer of 2016, interns Mackenzie Best and Yaal Dryer unpacked and sorted into drawers the Thomas V. Testa collection, and digitized the first 1,000 fossils. In 2017, two Women in Science interns, Kate Hodge and Dana Kahn, spent 6 weeks entering the data for 5,000 fossils into our database, numbering these fossils, and printing their labels. Having a well curated collection, as well as volunteer Jack Wittry, who has expert knowledge of Mazon Creek fossils, has also been crucial to the success of these projects. Mane Pritza, a Field Museum volunteer, began photographing these collections and has captured over 11,000 images. Janel Nelson, a former volunteer, has uploaded these images into our multimedia database and linked them to the corresponding records in the catalog module. James and Sylvia Konecny donated their 4,000-specimen Mazon Creek collection in December of 2017, ensuring that interns and volunteers will continue their curation work for at least the next two years.
