Abstract

This is a corrigendum to Gaia Collaboration (2018). It corrects errors in Appendix B, which describes the modelling of the Large and Small Magellanic Clouds (LMC and SMC). One of these errors also affects Fig. 18 of the paper, which shows the rotation curve and median radial motion in the LMC. No other results in the paper are affected. There should be no vector products in Appendix B, and everywhere a vector product appears should be a scalar product. This affects Eqs. (B.5), (B.8), (B.10), (B.12), (B.13), and (B.20). Equation (B.10), which defines one component of position within the plane of the galaxy, contains an additional typographical error, and it should have read (Farmula Presented) Equation (B.21) is incorrect. The factor of (ax + by + z) is applied to the wrong part of the equation. It should have read (Farmula Presented) This error affects the derived deprojected motions of stars in the LMC, and means that changes in the observational signature of the bulk motion away from the centre are not properly accounted for. The effect becomes more significant further from the centre. Figure 1 shows the resulting median tangential velocity, vT (the rotation curve), and median radial velocity vR as a function of de-projected radius R for the LMC, which is otherwise produced in the same way as before. The major differences between this and the equivalent figure in Gaia Collaboration (2018) are as follows The rotation curve reaches a greater velocity (~85 km s-1 versus ~75 km s-1) and remains flat beyond 6 kpc, as opposed to starting to fall. The difference in asymmetric drift for the blue and red populations is clearer the blue population, which is typically younger than the redder population, is rotating faster. The apparent outward motion of the stellar populations is much smaller. The blue population has almost no net radial motion, while the red population has one of .8 km s-1 (as opposed to ~20 km s-1). The difference in radial motion between the y < 0 and y > 0 populations is dramatically reduced, as is the difference between the value derived assuming the known line-of-sight bulk motion and the one derived leaving this value free. © 2020 ESO.

Abstract

Since the 1960s, hormonal contraceptives have become the most commonly used method of pregnancy prevention in the United States and the world. Oral contraceptives are used by a large percentage of women, including Christian women. There are known health risks to women demonstrated in research published since Pope Paul VI’s prophetic encyclical Humanae vitae in 1968. These risks include venous thrombosis, cardiovascular risks, and an increased risk of cancer. These risks are medically recognized with continued scientific debate on the degree. The risks are significantly increased with preexisting conditions and in certain demographic groups. Discussing known and potential treatment risks is a standard that is both accepted by the medical community and is increasingly expected by patients. This discussion can be accomplished by the mechanism and principle of informed consent. Depending on the circumstances, abstinence or fertility awareness-based methods (FABMs) should be presented to patients. FABMs are licit, safe, and effective methods of pregnancy prevention. Informed consent is the most effective means of providing patients with pertinent information on the significant risks of contraception.Summary:This article discusses the use of the informed consent to provide patients with information on the medical and ethical risks of oral contraceptives. FABMs and abstinence are presented as effective, safe, and licit preferences to oral contraceptives. Discussing known and potential treatment risks is accepted by the medical community and expected by patients (shared decision making). The authors discuss the historical context of Pope Paul VI’s encyclical Humanae vitae in relationship to the development and rapid adoption of oral contraceptives.

Abstract

Background Neighborhoods and their characteristics play a key role for establishing and maintaining health and wellbeing of their residents. However, before programs promoting health and wellbeing in the neighborhood can be planned and implemented, it is necessary to identify local needs for action. This is especially important for the stakeholders that work in the neighborhood (e.g., employees of the local community, headmasters of schools). We thus developed exemplary for Herzogenried -a neighborhood in the German city of Mannheim- a barometer that aims to assess and monitor health and wellbeing in the neighborhood and indicates potential needs for action. Methods We conducted a detailed literature search to identify indicators that were associated with health and wellbeing in neighborhoods. Based on the search we created a primary list of indicators, which we presented and discussed during 15 meetings with a total of 26 different stakeholders. Available data on the indicators agreed on were checked for accuracy, statistically processed, and visualized for incorporation into the barometer. Results The barometer consists of the following eight dimensions which in total include 80 indicators: population structure, population development, household structure, material wellbeing, education, family and upbringing, health, and personal security. The barometer also includes a map that displays structural characteristics of the neighborhood such as physicians, schools, supermarkets. An important challenge we faced was the availability of indicators as some of them were only accessible at the community level or for specific age groups. Conclusions The barometer offers a comprehensive overview on the neighborhood, provides first hints for the local stakeholders on needs for action, and helps to prioritize the issues that should be addressed to promote health and wellbeing in Herzogenried. It will also serve as a prototype for other neighborhoods in the future. Key messages The barometer was planned to serve as a transferable tool to identify and prioritize action steps for neighborhood development and to help promoting health and wellbeing of their residents. As the barometer displays indicators relevant for various community stakeholders it can serve to identify joint goals and thus foster stronger trans-sectoral collaboration at the neighborhood level.

Abstract

Context. The ESA Gaia mission provides a unique time-domain survey for more than 1.6 billion sources with G ≲ 21 mag. Aims. We showcase stellar variability in the Galactic colour-absolute magnitude diagram (CaMD). We focus on pulsating, eruptive, and cataclysmic variables, as well as on stars that exhibit variability that is due to rotation and eclipses. Methods. We describe the locations of variable star classes, variable object fractions, and typical variability amplitudes throughout the CaMD and show how variability-related changes in colour and brightness induce "motions". To do this, we use 22 months of calibrated photometric, spectro-photometric, and astrometric Gaia data of stars with a significant parallax. To ensure that a large variety of variable star classes populate the CaMD, we crossmatched Gaia sources with known variable stars. We also used the statistics and variability detection modules of the Gaia variability pipeline. Corrections for interstellar extinction are not implemented in this article. Results. Gaia enables the first investigation of Galactic variable star populations in the CaMD on a similar, if not larger, scale as was previously done in the Magellanic Clouds. Although the observed colours are not corrected for reddening, distinct regions are visible in which variable stars occur. We determine variable star fractions to within the current detection thresholds of Gaia. Finally, we report the most complete description of variability-induced motion within the CaMD to date. Conclusions. Gaia enables novel insights into variability phenomena for an unprecedented number of stars, which will benefit the understanding of stellar astrophysics. The CaMD of Galactic variable stars provides crucial information on physical origins of variability in a way that has previously only been accessible for Galactic star clusters or external galaxies. Future Gaia data releases will enable significant improvements over this preview by providing longer time series, more accurate astrometry, and additional data types (time series BP and RP spectra, RVS spectra, and radial velocities), all for much larger samples of stars. © 2019 ESO.

Abstract

Summary Introduction The transition from school to university may be accompanied by different changes in lifestyle. We aimed to investigate whether students’ physical activity (PA) differs between school and university and which role change of residence plays. Summary of facts and results We analyzed data on 689 university students (69.5% female; mean: 22.7 years). The majority changed PA compared to school (less: 45.4%, more: 36.5%). Among those who were at the beginning of their studies and those who changed residence for the start of studies, the proportion of individuals having reduced PA was higher compared to their reference groups of students in higher semesters and students having not changed residence, respectively. Students visiting their hometown more frequently and staying there during semester break were more likely to have reduced PA. Conclusion Students who changed residence for starting studies seem to be a vulnerable group future intervention campaigns should focus on. Supporting those students to stay physically active during studies may be important to help them starting an active and healthy work life after graduation. Additionally, freshmen at universities may need more support to have the opportunity to stay physically active.

Abstract

Context. The second Gaia data release (Gaia DR2) contains high-precision positions, parallaxes, and proper motions for 1.3 billion sources as well as line-of-sight velocities for 7.2 million stars brighter than GRVS = 12 mag. Both samples provide a full sky coverage. Aims. To illustrate the potential of Gaia DR2, we provide a first look at the kinematics of the Milky Way disc, within a radius of several kiloparsecs around the Sun. Methods. We benefit for the first time from a sample of 6.4 million F-G-K stars with full 6D phase-space coordinates, precise parallaxes (σω/ω/≤ 20%), and precise Galactic cylindrical velocities (median uncertainties of 0.9-1.4 km s-1 and 20% of the stars with uncertainties smaller than 1 km s-1 on all three components). From this sample, we extracted a sub-sample of 3.2 million giant stars to map the velocity field of the Galactic disc from ∼5 kpc to ∼13 kpc from the Galactic centre and up to 2 kpc above and below the plane. We also study the distribution of 0.3 million solar neighbourhood stars (r < 200 pc), with median velocity uncertainties of 0.4 km s-1, in velocity space and use the full sample to examine how the over-densities evolve in more distant regions. Results. Gaia DR2 allows us to draw 3D maps of the Galactocentric median velocities and velocity dispersions with unprecedented accuracy, precision, and spatial resolution. The maps show the complexity and richness of the velocity field of the galactic disc. We observe streaming motions in all the components of the velocities as well as patterns in the velocity dispersions. For example, we confirm the previously reported negative and positive galactocentric radial velocity gradients in the inner and outer disc, respectively. Here, we see them as part of a non-axisymmetric kinematic oscillation, and we map its azimuthal and vertical behaviour. We also witness a new global arrangement of stars in the velocity plane of the solar neighbourhood and in distant regions in which stars are organised in thin substructures with the shape of circular arches that are oriented approximately along the horizontal direction in the U - V plane. Moreover, in distant regions, we see variations in the velocity substructures more clearly than ever before, in particular, variations in the velocity of the Hercules stream. Conclusions. Gaia DR2 provides the largest existing full 6D phase-space coordinates catalogue. It also vastly increases the number of available distances and transverse velocities with respect to Gaia DR1. Gaia DR2 offers a great wealth of information on the Milky Way and reveals clear non-axisymmetric kinematic signatures within the Galactic disc, for instance. It is now up to the astronomical community to explore its full potential. © ESO 2018.

Abstract

Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry and photometry are unprecedented. Aims. We highlight the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD). Gaia allows us to present many different HRDs, depending in particular on stellar population selections. We do not aim here for completeness in terms of types of stars or stellar evolutionary aspects. Instead, we have chosen several illustrative examples. Methods. We describe some of the selections that can be made in Gaia DR2 to highlight the main structures of the Gaia HRDs. We select both field and cluster (open and globular) stars, compare the observations with previous classifications and with stellar evolutionary tracks, and we present variations of the Gaia HRD with age, metallicity, and kinematics. Late stages of stellar evolution such as hot subdwarfs, post-AGB stars, planetary nebulae, and white dwarfs are also analysed, as well as low-mass brown dwarf objects. Results. The Gaia HRDs are unprecedented in both precision and coverage of the various Milky Way stellar populations and stellar evolutionary phases. Many fine structures of the HRDs are presented. The clear split of the white dwarf sequence into hydrogen and helium white dwarfs is presented for the first time in an HRD. The relation between kinematics and the HRD is nicely illustrated. Two different populations in a classical kinematic selection of the halo are unambiguously identified in the HRD. Membership and mean parameters for a selected list of open clusters are provided. They allow drawing very detailed cluster sequences, highlighting fine structures, and providing extremely precise empirical isochrones that will lead to more insight in stellar physics. Conclusions. Gaia DR2 demonstrates the potential of combining precise astrometry and photometry for large samples for studies in stellar evolution and stellar population and opens an entire new area for HRD-based studies. © ESO 2018.

Abstract

Context. The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Data Release 2 (DR2) contains the observations of a selected sample of 14,099 SSOs. These asteroids have been already identified and have been numbered by the Minor Planet Center repository. Positions are provided for each Gaia observation at CCD level. As additional information, complementary to astrometry, the apparent brightness of SSOs in the unfiltered G band is also provided for selected observations. Aims. We explain the processing of SSO data, and describe the criteria we used to select the sample published in Gaia DR2. We then explore the data set to assess its quality. Methods. To exploit the main data product for the solar system in Gaia DR2, which is the epoch astrometry of asteroids, it is necessary to take into account the unusual properties of the uncertainty, as the position information is nearly one-dimensional. When this aspect is handled appropriately, an orbit fit can be obtained with post-fit residuals that are overall consistent with the a-priori error model that was used to define individual values of the astrometric uncertainty. The role of both random and systematic errors is described. The distribution of residuals allowed us to identify possible contaminants in the data set (such as stars). Photometry in the G band was compared to computed values from reference asteroid shapes and to the flux registered at the corresponding epochs by the red and blue photometers (RP and BP). Results. The overall astrometric performance is close to the expectations, with an optimal range of brightness G ∼ 12 - 17. In this range, the typical transit-level accuracy is well below 1 mas. For fainter asteroids, the growing photon noise deteriorates the performance. Asteroids brighter than G ∼ 12 are affected by a lower performance of the processing of their signals. The dramatic improvement brought by Gaia DR2 astrometry of SSOs is demonstrated by comparisons to the archive data and by preliminary tests on the detection of subtle non-gravitational effects. © ESO 2018.

Abstract

Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighter than magnitude 21. In addition epoch astrometry and photometry are provided for a modest sample of minor planets in the solar system. Aims. A summary of the contents of Gaia DR2 is presented, accompanied by a discussion on the differences with respect to Gaia DR1 and an overview of the main limitations which are still present in the survey. Recommendations are made on the responsible use of Gaia DR2 results. Methods. The raw data collected with the Gaia instruments during the first 22 months of the mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC) and turned into this second data release, which represents a major advance with respect to Gaia DR1 in terms of completeness, performance, and richness of the data products. Results. Gaia DR2 contains celestial positions and the apparent brightness in G for approximately 1.7 billion sources. For 1.3 billion of those sources, parallaxes and proper motions are in addition available. The sample of sources for which variability information is provided is expanded to 0.5 million stars. This data release contains four new elements: broad-band colour information in the form of the apparent brightness in the GBP (330-680 nm) and GRP (630-1050 nm) bands is available for 1.4 billion sources; median radial velocities for some 7 million sources are presented; for between 77 and 161 million sources estimates are provided of the stellar effective temperature, extinction, reddening, and radius and luminosity; and for a pre-selected list of 14 000 minor planets in the solar system epoch astrometry and photometry are presented. Finally, Gaia DR2 also represents a new materialisation of the celestial reference frame in the optical, the Gaia-CRF2, which is the first optical reference frame based solely on extragalactic sources. There are notable changes in the photometric system and the catalogue source list with respect to Gaia DR1, and we stress the need to consider the two data releases as independent. Conclusions. Gaia DR2 represents a major achievement for the Gaia mission, delivering on the long standing promise to provide parallaxes and proper motions for over 1 billion stars, and representing a first step in the availability of complementary radial velocity and source astrophysical information for a sample of stars in the Gaia survey which covers a very substantial fraction of the volume of our galaxy. © ESO 2018.

Abstract

The US Army RDECOM CERDEC Night Vision & Electronic Sensors Directorate (NVESD) has a dynamic applied research program in sensor fusion for a wide variety of defense & defense related applications. This paper highlights efforts under the NVESD Sensor Fusion Testbed (SFTB) in the area of detection of moving vehicles with a network of image and acoustic sensors. A sensor data collection was designed and conducted using a variety of vehicles. Data from this collection included signature data of the vehicles as well as moving scenarios. Sensor fusion for detection and classification is performed at both the sensor level and the feature level, providing a basis for making tradeoffs between performance desired and resources required. Several classifier types are examined (parametric, nonparametric, learning). The combination of their decisions is used to make the final decision.

Abstract

This nuts-and-bolts guide examines all aspects of an M&A due diligence--from coming to the decision to acquire a company, to who should be on the due diligence team, to the actual process and the final report and post-closing follow up. It advocates a focus on both risk mitigation and shareholder value creation, and emphasizes a holistic approach that spans from planning to post-acquisition integration. The tentative contents is: (1) Introduction; (2) Planning for value creation: growth strategy; (3) Engagement and pursuit; (4) Preparing for due diligence; (5) Validation of value: performing due diligence; (6) Assessment of due diligence results; (7) Optimizing value: post diligence negotiation; (8) Extracting value: post-transaction integration.

Abstract

The US Army RDECOM CERDEC Night Vision & Electronic Sensors Directorate has a dynamic applied research program in sensor fusion for a wide variety of defense & defense related applications. This paper provides an overview of the on going research at NVESD related to fusing a mixture of active and passive sensors for countermine, dismounted & mounted soldiers, aviation and unattended ground sensor applications. Highlighted are new techniques in image registration and sensor fusion ion that enable the detection of moving vehicles with a network of image and acoustic sensors. A set of experiments was designed and conducted using a variety of vehicles and scenarios. The incremental value (in terms of error probability) added to the acoustic information by the image sensors (visible and infrared wavelength cameras) is assessed in combination with the fusion techniques themselves. The approach specifically accounts for the effects of location, speed, weather, and background (acoustic, visible, and infrared). Sensor fusion for detection and classification is preformed at both the sensor level and the feature level providing a basis for making tradeoffs between performance desired and resources required. Several classifier types are examined (parametric, nonparametric, learning). The combination of their decisions is used to make the final decision. Keywords: Tracking, fusion, sensor fusion, vehicle detection, detection, location.

Abstract

The determination of a good decomposition of a manufacturing system into manufacturing cells, when various manufacturing processes are available for each type of product, is addressed. A simple twofold algorithm is proposed. The first part of the algorithm aims at defining the proportion of each product type to manufacture, using each of the available manufacturing processes. The result is a mono-manufacturing process problem, i.e a problem which consists of finding a good decomposition of a manufacturing system into cells when only one manufacturing process is available for each type of product. The second part of the algorithm uses an approach previously presented by the authors (1989) to solve the mono-manufacturing process problem. Also presented is a numerical example to illustrate the approach. >
