Abstract:

BackgroundThe Mental Health Recovery Star (MHRS) is a popular outcome measure rated collaboratively by staff and service users, but its psychometric properties are unknown.AimsTo assess the MHRS's acceptability, reliability and convergent validity.MethodA total of 172 services users and 120 staff from in-patient and community services participated. Interrater reliability of staff-only ratings and test–retest reliability of staff-only and collaborative ratings were assessed using intraclass correlation coefficients (ICCs). Convergent validity between MHRS ratings and standardised measures of social functioning and recovery was assessed using Pearson correlation. The influence of collaboration on ratings was assessed using descriptive statistics and ICCs.ResultsThe MHRS was relatively quick and easy to use and had good test–retest reliability, but interrater reliability was inadequate. Collaborative ratings were slightly higher than staff-only ratings. Convergent validity suggests it assesses social function more than recovery.ConclusionsThe MHRS cannot be recommended as a routine clinical outcome tool but may facilitate collaborative care planning.

Abstract:

This study examines the influence of job resourcefulness on individual crafting and collaborative crafting through work engagement as a mediator variable. This research uses a quantitative approach, using a survey to collect data. The sample in this study amounted to 100 employees from 4-star hotels throughout Surabaya who are registered in the Traveloka. This research used Structural Equation Model (SEM) with the assistance of Smart PLS 3.0 software as the statistical analysis. This research shows that job resourcefulness has a significant positive direct influence on individual crafting and has a significant and positive individual influence on individual crafting through work engagement on 4-star hotel employees. Job resourcefulness is found to have a significant and negative direct influence on collaborative crafting. Job resourcefulness has a significantly direct indirect influence on collaborative crafting through work engagement with 4-star hotel employees. The implications of this study need to increase the collaborative crafting employees by involving all employees in the procurement of discussion forums, so they can harmonize the thought between employees in the company so that the existence of the forum there will be similarities of perceptions so that work collaboration can be well established.

Abstract:

The STAR collaboration aims to study polarized proton-proton collisions at RHIC. The emphasis of the spin run this year is on transverse single spin asymmetries. Beyond 2001, we aim to determine directly and precisely the gluon polarization, as well as the polarizations of the u, [Formula: see text], d and [Formula: see text] quarks in the proton by measuring in addition longitudinal and double spin asymmetries. Furthermore, we aim to measure for the first time the quark transversity distributions. These measurements will improve substantially the knowledge and understanding of the spin structure of the nucleon.

Abstract:

Nanotechnologies have been regarded as general-purpose, and interdisciplinary technology converged with different implications of technologies. This paper aims to explore the global Nano collaboration of research and development (R&D) by patent analysis to realize the sustainable development of nanotechnology and investigate the influence of global R&D collaboration on patent quality. The primary findings indicated that the number of issued patents grew sharply since 2002, and the major collaborative fields in terms of nanotechnology are nanoelectronic and nanomaterials. Finally, the collaboration among star assigners, global partnership, and the indicator of patent centrality had a positive impact on patent quality, except that university-industry collaboration did not show a significant effect on patent quality. One part of the reason is that industries have not yet fully recognised nanotechnology opportunities with a risk-averse attitude toward market uncertainties. Overall, the relationship of global R&D collaboration is an essential factor in promoting the sustainable development of the patent quality of nanotechnology. An effective patenting strategy and high-quality application of nanotechnology R&D could secure protection for innovations to reinforce core competitiveness in the business.

AbstractWe discuss the recent detection of a strong, organized magnetic field in the bright, broad-line B2V star, HD 142184, using the ESPaDOnS spectropolarimeter on the CFHT as part of the Magnetism in Massive Stars (MiMeS) survey. We find a rotational period of 0.50833 days, making it the fastest-rotating, non-degenerate magnetic star ever detected. Like the previous rapid-rotation record holder HR 7355 (also discovered by MiMeS: Oksala et al. 2010, Rivinius et al. 2010), this star shows emission line variability that is diagnostic of a structured magnetosphere.

Abstract:

In the past few years, several dramatic incidents have spurred renewed efforts to control violence and prevent crime in schools. Although it has yet to become a matter of much public discussion, what is particularly notable about many of these efforts is the increased collaboration of criminal and juvenile justice agencies with schools in their capacity as formal agents of control. In the present study, the authors evaluate one program that embodies this type of collaboration—Specialized Treatment and Rehabilitation (STAR). STAR is an innovative juvenile boot camp program in a public school setting that is operated through the combined efforts of the school, the juvenile court, and the juvenile probation department. Results of the evaluation revealed that although the program had a relatively small impact on recidivism, perceptions garnered from parents, teachers, and STAR participants were quite favorable for the program overall.

High-precision radial-velocity studies of four star-forming regions: λ Orionis, NGC 2264, the Trapezium cluster and Taurus-Auriga, are completed or in process (in collaboration with Latham, Marschall and Hartmann). Single-order (∼ 50 Å, central wavelength 5200 Å) echelle spectra have been obtained for late-type pre-main sequence stars. Measurement errors of 0.7 – 1.5 km/sec are typical, although some stars do not permit any radial-velocity measurement due to stellar rotation or spectral peculiarities.

Abstract:

In this paper we present a wheeled robot platform for child-parent robot collaboration. The new robot, named Big STAR (BSTAR), is fitted with a tail that can act as a ramp to carry and deploy a child RSTAR that can crawl between small cracks and underneath obstacles. Both robots possess sprawling capabilities inspired from insects, enabling them to transform their external geometry and dynamics to overcome a variety of obstacles. The BSTAR can travel at speeds of up to 1.4 m/s, carry payloads of more than five kilograms and travel over rough terrains. The collaboration between the two robots substantially increases their navigability and their capability to overcome obstacles. It increases their working distance and scouting area since the larger robot can act as a charging point for the smaller one. We first describe the design of the newly developed parent BSTAR robot and provide a kinematic and dynamic analysis that determines the force requirements of the robots when collaborating, followed by an evaluation of their mechanical and electrical requirements. We show that under multiple challenging scenarios the robot pair can successfully overcome a variety of obstacles.

Abstract:

Abstract We present a large-scale study of stellar rotation for T Tauri stars in the Orion star-forming complex. We use the projected rotational velocity ( v sin ( i ) ) estimations reported by the APOGEE-2 collaboration as well as individual masses and ages derived from the position of the stars in the HR diagram, considering Gaia-EDR3 parallaxes and photometry plus diverse evolutionary models. We find an empirical trend for v sin ( i ) decreasing with age for low-mass stars (0.4M ⊙ < M * < 1.2M ⊙). Our results support the existence of a mechanism linking v sin ( i ) to the presence of accreting protoplanetary disks, responsible for regulating stellar rotation on timescales of about 6 Myr, which is the timescale in which most of the T Tauri stars lose their inner disk. Our results provide important constraints to models of rotation in the early phases of evolution of young stars and their disks.

Abstract:

Abstract The measurement of the macroscopic properties of a neutron star, whether in binary or in an isolated system, provides us with a key opportunity to place a stringent constraint on its equation of state. In this paper, we perform Bayesian model selection on a wide variety of neutron star equations of state using multi-messenger observations. In particular, (i) we use the mass and tidal deformability measurements from two binary neutron star merger events, GW170817 and GW190425; and (ii) we use the simultaneous mass–radius measurements of PSR J0030+0451 and PSR J0740+6620 by the NICER collaboration, while the latter has been analyzed by the joint NICER/radio/XMM-Newton collaboration. Among the 31 equations of state considered in this analysis, we are able to rule out different variants of the MS1 family, SKI5, H4, and WFF1 decisively, which are either extremely stiff or soft equations of state. The most preferred equation of state model turns out to be AP3 (or MPA1), which predicts the radius and dimensionless tidal deformability of a 1.4 M ⊙ neutron star to be 12.10 (12.50) km and 393 (513), respectively.

AbstractThe MACHO Collaboration’s search for baryonic dark matter via its gravitational microlensing signature has generated a massive database of time ordered photometry of millions of stars in the LMC and the bulge of the Milky Way. The search’s experimental design and capabilities are reviewed and the dark matter results are briefly noted. Preliminary analysis of the ~ 39,000 variable stars discovered in the LMC database is presented and examples of periodic variables are shown. A class of a periodically variable Be star is described which is the closest background to microlensing which has been found. Plans for future work on variable stars using the MACHO data are described.

AbstractOn August 17, 2017 LIGO/Virgo detected a binary neutron star via gravitational waves. We observed 70 sq-degrees in the LIGO/Virgo spatial localization with the DECam on the 4m Blanco telescope covering 80% of the final map. Our group independently discovered an optical counterpart in NGC 4993. We searched our entire imaged region: the object in NGC 4993 was the only viable candidate. Our observations of NGC4993 show complicated morphology but simple star formation history. Our x-ray and radio observations indicate an off-axis jet as afterglow. Our high-cadence optical and infrared spectra show a source that must be described by at least two components, one of which is dominated by the r-process nucleosynthesis elements characteristic of a kilonova. Our modeling of the light curve demonstrates such a model in which 0.05 M⊙ of material is ejected from the system. Finally, we discuss the first standard siren measurement of H0.

Full text

Abstract:

An airline alliance is a group of member airlines that seek to achieve the same goals through routes and airports. Hence, airports’ connectivity plays an essential role in understanding the linkage between different markets, especially the impact of neighboring airports on focal airports. An airline alliance airport network (AAAN) comprises airports as nodes and routes as edges. It could reflect a clear collaborative proportion within AAAN and competitive routes between AAANs. Recent studies adopted an airport- or route-centric perspective to evaluate the relationship between airline alliances and their member airlines; meanwhile, they mentioned that an airport community could provide valuable air transportation information because it considers the entire network structure, including the impacts of the direct and indirect routes. The objectives are to identify spatial patterns of market region in an airline alliance and characterize the differences among airline alliances (Oneworld, Star Alliance, and SkyTeam), including regions of collaboration, competition, and dominance. Our results show that Star Alliance has the highest collaboration and international market dominance among three airline alliances. The most competitive regions are Asia-Pacific, West Asia, Europe, and North and Central America. The network approach we proposed identifies market characteristics, highlights the region of market advantages in the airline alliance, and also provides more insights for airline and airline alliances to extend their market share or service areas.

Abstract:

AbstractShort period binary systems containing magnetic Ap stars are anomalously rare. This apparent anomaly may provide insight into the origin of the magnetic fields in theses stars. As an early investigation of this, we observed three close binary systems that have been proposed to host Ap stars. Two of these systems (HD 22128 and HD 56495) we find contain Am stars, but not Ap stars. However, for one system (HD 98088) we find the primary is indeed an Ap star, while the secondary is an Am star. Additionally, the Ap star is tidally locked to the secondary, and the predominately dipolar magnetic field of the Ap star is roughly aligned with the secondary. Further investigations of HD 98088 are planned by the BinaMIcS collaboration.

Abstract:

The goal of this article is to contribute to the literature on interdisciplinary collaboration by suggesting that efficient collaboration occurs when boundaries disappear (and not by trying to bridge them). It is using the constitutive approach to organization that I intend to comprehend this “dissolving of boundaries”, but also using Star and Griesemer notion of boundary-object as a framework. This conceptual articulation allows me to reveal the “making together” as the means for the disciplinary boundaries disappearance. This paper show how an architectural “project” becomes a site for communication enabling collaboration between specialists from various disciplines.

AbstractThe DESGW program is a collaboration between members of the Dark Energy Survey, the wider astronomical community, and the LIGO-Virgo Collaboration to search for optical counterparts of gravitational wave events, such as those expected from binary neutron star mergers or neutron star-black hole mergers. While binary black hole (BBH) events are not expected to produce an electromagnetic (EM) signature, emission is certainly not impossible. The DESGW program has performed follow-up observations of four BBH events detected by LIGO in order to search for any possible EM counterpart. Failure to find such counterparts is still relevant in that it produces limits on optical emission from such events. This is a review of follow-up results from O1 BBH events and a discussion of the status of ongoing uniform re-analysis of all BBH events that DESGW has followed up to date.

Abstract:

Self-similarity of jet production in pp and [Formula: see text] collisions is studied in the framework of z-scaling. Inclusive jet transverse momentum distributions measured by the STAR Collaboration at RHIC, the CDF and D∅ Collaborations at Tevatron and the CMS and ATLAS Collaborations at LHC are analyzed. The experimental spectra are compared with next-to-leading order QCD calculations in pT- and z-presentations. It is shown that self-similar features of jet cross-sections manifested by the z-scaling give strong restriction on the scaling function ψ(z) at high z. New results on energy and angular independence and asymptotic behavior of ψ(z) are discussed. The obtained results are considered as confirmation of self-similarity of jet production, fractality of hadron structure and locality of constituent interactions at small scales.

Abstract:

A collaboration between Nobeyama Radio Observatory and UKIRT has produced high resolution images in CO and H2 of the star forming regions DR21, Orion, and M17. In each case the images in the two species are remarkably similar. This is a striking result, for the H2 traces a very hot component of the interstellar medium, either shocked to temperatures around 2000 K or highly excited by ultraviolet fluorescence.

Abstract:

The stakeholder network in a building project can influence the process of adopting sustainable building practice. Complexity of construction projects calls for integrated modes of collaboration, while the excess inertia among stakeholders resulted in sluggish adoption of sustainable design and technologies. This study examined buildings that both had and had not adopted Leadership in Energy and Environmental Design and/or ENERGY STAR in the New York metropolitan area, built, or went through major renovation between 1998 and 2013. Secondary datasets from multiple sources, including a private building database company, US Green Building Council, and the US Environmental Protection Agency, were combined based on building address and used for analysis. Stakeholders involved in those projects were retrospectively identified to understand the diffusion of innovation. The analysis included a total of 205 projects and 273 organizations. Findings suggest that having an architect who had worked on ENERGY STAR project(s) increased the likelihood of adopting ENERGY STAR. However, stakeholders' previous work collaboration was not associated with the adoption of sustainable programs. The method of utilizing multiple secondary datasets was tested to contribute to the methodology of building research by enabling the accumulation of knowledge.

Abstract:

The MACHO Collaboration has produced a variable star catalog of the Magellanic Clouds which is a rich source of eclipsing binary systems. I will review the techniques that have been used by MACHO for identifying eclipsing binaries in a relatively automated fashion which is necessitated by the more than 230000 variable light curves cataloged. We have identified about 6000 eclipsing binaries using these techniques. These systems have periods ranging from hours to more than 1000 days. I will survey the binary star data from MACHO and highlight its use in investigating topics spanning the physics of supersoft gamma-ray sources to the distance of the Large Magellanic Cloud and point to future directions of research using this public resource.

Abstract The STAR-VA program was an initiative out of what is now called the VA Office of Mental Health and Suicide Prevention, partnering with the national Offices of Geriatrics and Extended Care and Nursing Services. Ongoing collaboration with these national, as well as regional and medical-center-level leaders, has been critical for informing program implementation and dissemination strategies. We will discuss several key partnered strategies, including (1) linking STAR-VA to national CLC systematic quality improvement efforts; (2) engaging national inter-office program leaders in decisions about outreach to and inclusion of facilities in STAR-VA training and implementation; (3) training local STAR-VA champions on strategies for engaging local leadership support; (4) briefing leaders across the system with program updates; and (5) using national VA data to inform STAR-VA sustained implementation. Discussion will address challenges and opportunities for engaging leadership stakeholders in facilitating sustained implementation of evidence-based programs.

Abstract:

Abstract. The Double Star Programme (DSP) was first proposed by China in March, 1997 at the Fragrant Hill Workshop on Space Science, Beijing, organized by the Chinese Academy of Science. It is the first mission in collaboration between China and ESA. The mission is made of two spacecraft to investigate the magnetospheric global processes and their response to the interplanetary disturbances in conjunction with the Cluster mission. The first spacecraft, TC-1 (Tan Ce means "Explorer"), was launched on 29 December 2003, and the second one, TC-2, on 25 July 2004 on board two Chinese Long March 2C rockets. TC-1 was injected in an equatorial orbit of 570x79000 km altitude with a 28° inclination and TC-2 in a polar orbit of 560x38000 km altitude. The orbits have been designed to complement the Cluster mission by maximizing the time when both Cluster and Double Star are in the same scientific regions. The two missions allow simultaneous observations of the Earth magnetosphere from six points in space. To facilitate the comparison of data, half of the Double Star payload is made of spare or duplicates of the Cluster instruments; the other half is made of Chinese instruments. The science operations are coordinated by the Chinese DSP Scientific Operations Centre (DSOC) in Beijing and the European Payload Operations Service (EPOS) at RAL, UK. The spacecraft and ground segment operations are performed by the DSP Operations and Management Centre (DOMC) and DSOC in China, using three ground station, in Beijing, Shanghai and Villafranca.

Abstract:

We present an overview of the recent results obtained by the STAR Collaboration at RHIC.We report the beam energy dependence of directed flow of strange particles. These results support the assumption, that directed flow is formed before hadronization and observed particles are formed via coalescence of constituent quarks. First evidence of a non-zero directed flow of D0 meson is reported. We present the precision measurement of elliptic flow of D0 meson and the first measurement of Λc baryon in Au+Au collisions at $\rad{}{s_{NN} } = 200\,{\rm{GeV}}$, which suggests thermalization of charm quarks. We report results of global Λ polarization measurements in Au+Au collisions, together with the investigation of polarization dependence of centrality and transverse momentum pT. Results from the STAR fixed-target program show good agreement with previously obtained results. A precise measurement of the $_{{\rm{\Lambda }}}^{3} H$ lifetime is presented. Mesonic decay modes are used to reconstruct the $_{{\rm{\Lambda }}}^{3} H$ from Au+Au collisions. The measured lifetime is about 50% shorter than the one of a free Λ, indicating a strong hyperon-nucleon interaction in the hypernucleus system. Finally, we give an outlook to detector upgrades for the Beam Energy Scan phase II.

Abstract:

A three-phase Delphi study was used to investigate an emerging community for research data management in Norway and their understanding and application of data management plans (DMPs). The findings reveal visions of what the DMP should be as well as different practice approaches, yet the stakeholders present common goals. This paper discusses the different perspectives on the DMP by applying Star and Griesemer’s theory of boundary objects (Star & Griesemer, 1989). The debate on what the DMP is and the findings presented are relevant to all research communities currently implementing DMP procedures and requirements. The current discussions about DMPs tend to be distant from the active researchers and limited to the needs of funders and institutions rather than to the usefulness for researchers. By analysing the DMP as a boundary object, plastic and adaptable yet with a robust identity (Star & Griesemer, 1989), and by translating between worlds where collaboration on data sharing can take place we expand the perspectives and include all stakeholders. An understanding of the DMP as a boundary object can shift the focus from shaping a DMP which fulfils funders’ requirements to enabling collaboration on data management and sharing across domains using standardised forms.

Abstract:

Transverse momentum spectra of proton, deuteron, and triton in gold-gold (Au-Au) collisions at 54.4 GeV are analyzed in different centrality bins by the blast wave model with Tsallis statistics. The model results are approximately in agreement with the experimental data measured by STAR Collaboration in special transverse momentum ranges. We extracted the kinetic freeze-out temperature, transverse flow velocity, and freeze-out volume from the transverse momentum spectra of the particles. It is observed that the kinetic freeze-out temperature is increasing from the central to peripheral collisions. However, the transverse flow velocity and freeze-out volume decrease from the central to peripheral collisions. The present work reveals the mass dependent kinetic freeze-out scenario and volume differential freeze-out scenario in collisions at STAR Collaboration. In addition, parameter q characterizes the degree of nonequilibrium of the produced system, and it increases from the central to peripheral collisions and increases with mass .

Abstract:

Large vorticities in the Quark–Gluon Plasma produced in peripheral collisions studied by the STAR collaboration at the RHIC facility have been deduced from observations of polarizations of [Formula: see text] and [Formula: see text] hyperons. Recently, the STAR collaboration has reported on the dependence of these polarizations on centrality, at impact energy 200 GeV and relatively large centralities [Formula: see text]. The polarizations increase slowly with centrality, up to perhaps [Formula: see text]. Here we use a holographic model of the vortical QGP to make predictions regarding these polarizations for smaller centralities, ranging from 5–20%. The model predicts that as one moves downwards from 20%, [Formula: see text] polarizations at first decrease but then increase sharply, in a characteristic pattern which should be readily detected if collisions can be studied at impact energies below 200 GeV and centrality as low as 5–10%. The effect should be most evident at moderate impact energies below 200 GeV, so we give predictions for impact energy 27 GeV.

Abstract:

AbstractWe first present a recently developed three-dimensional chemodynamic code for galaxy evolution from the Kiev–Kiel collaboration. It follows the evolution of all components of a galaxy, such as dark matter, stars, molecular clouds and diffuse interstellar matter. Dark matter and stars are treated as collisionless N-body systems. The interstellar matter is numerically described by a smoothed particle hydrodynamics approach for the diffuse (hot) gas and a sticky particle scheme for the (cool) molecular clouds. Physical processes, such as star formation, stellar death, or condensation and evaporation processes of clouds interacting with the ISM are described locally. An example application of the model to a star forming dwarf galaxy will be shown for comparison with other codes. Secondly, we will discuss new kinds of exotic chemodynamic processes, as they occur in dense gas–star systems in galactic nuclei, such as non-standard ‘drag’-force interactions, destructive and gas-producing stellar collisions. Their implementation in one-dimensional dynamic models of galactic nuclei is presented. Future prospects to generalise these to three dimensions are in progress and will be discussed.

Abstract:

The influence of Bose–Einstein statistics on multi-particle production characterized for various systems and energies by the STAR collaboration provides interesting information about the space-time dynamics of relativistic heavy-ion collisions at RHIC. We present the centrality and transverse mass dependence measurements of the two-pion interferometry in Au + Au collisions at [Formula: see text] and Cu + Cu collisions at [Formula: see text] and 200 GeV. We compare the new data with previous STAR measurements from p + p , d + Au and Au + Au collisions at [Formula: see text]. In all systems and centralities, HBT radii decrease with transverse mass in a similar manner, which is qualitatively consistent with collective flow. The scaling of the apparent freeze-out volume with the number of participants and charged particle multiplicity is studied. Measurements of Au + Au collisions at same centralities and different energies yield different freeze-out volumes, which mean that N part is not a suitable scaling variable. The multiplicity scaling of the measured HBT radii is found to be independent of colliding system and collision energy.
