BACKGROUND Although people with cancer want and need information from their oncologists, patients and oncologists often disagree about what information was discussed during clinical interactions. Most patients have companions present during oncology visits; we investigated whether companions process information more accurately than patients. Specifically, we examined whether patients and compan...

BACKGROUND Patients engage in medical tourism when they privately obtain a medical care abroad. Previous research shows that many medical tourists travel abroad with friends and family members who provide support and assistance. Meanwhile, very little is known about this important stakeholder group, referred to here as caregiver-companions. In this article we examine the challenges that can be ...

We present JHK S observations of 22 intermediate-mass stars in the Scorpius-Centaurus OB association, obtained with the NAOS/CONICA system at the ESO Very Large Telescope. This survey was performed to determine the status of (sub)stellar candidate companions of Sco OB2 member stars of spectral type A and late-B. The distinction between companions and background stars is made on the basis of a c...

This paper presents some of the requirements for the design of long-term affect sensitive and socially interactive companions. Research conducted in the EU project LIREC (LIving with Robots and intEractive Companions) envisage some capabilities including affect sensitivity, memory and learning, cognitive and expressive behaviour, personalisation and embodiment, highlighting the key issues that ...

We present Spitzer IRAC photometry of white dwarf remnants of 14 stars with M = 3− 5 M⊙. We do not detect mid-infrared excess around any of our targets. By demanding a 3σ photometric excess at 4.5 μm for unresolved companions, we rule out planetary mass companions down to 5, 7, or 10 MJ for 13 of our targets based on the Burrows et al. (2003) substellar cooling models. Combined with previous IR...

this study was done to explore the views of patients and their companions concerning endotracheal intubation training on newly deceased patients and the necessity of obtaining their consent in this regard. in this cross-sectional descriptive analytical study, we used a questionnaire to collect data through structured interviews conducted by the researcher on patient discharge day. a convenient ...

We present the results of a survey for stellar and substellar companions to 82 young stars in the nearby OB association Upper Scorpius. This survey used nonredundant aperture mask interferometry to achieve typical contrast limits of K 5Y6 at the diffraction limit, revealing 12 new binary companions that lay below the detection limits of traditional high-resolution imaging; we also summarize a c...

A subset of 51 Hipparcos astrometric binaries among FG dwarfs within 67 pc has been surveyed with the Near-Infrared Coronagraphic Imager adaptive optics system at Gemini-S, directly resolving for the first time 17 subarcsecond companions and 7 wider ones. Using these data together with published speckle interferometry of 57 stars, we compare the statistics of resolved astrometric companions wit...

We examine the relationship between the frequency of close companions (stellar and planetary companions with orbital periods<5 yr) and the metallicity of their Sun-like ( FGK) hosts. We confirm and quantify a 4 positive correlation between host metallicity and planetary companions. We find little or no dependence on spectral type or distance in this correlation. In contrast to the metallicity d...
