It is expected that an average protostar will undergo at least one impulsive interaction with a neighbouring protostar whilst a large fraction of its mass is still in a massive, extended disc. Such interactions must have a significant impact upon the evolution of the protostars and their discs. We have carried out a series of simulations of coplanar encounters between two stars, each possessing...
It appears that most stars are born in clusters, and that at birth most stars have circumstellar discs which are comparable in size to the separations between the stars. Interactions between neighbouring stars and discs are therefore likely to play a key rôle in determining disc lifetimes, stellar masses, and the separations and eccentricities of binary orbits. Such interactions may also cause ...
OBJECTIVE To identify and classify all clinical decisions that emerged in a sample of patient-physician encounters and compare different categories of decisions across clinical settings and personal characteristics. DESIGN Cross-sectional descriptive evaluation of hospital encounters videotaped in 2007-2008 using a novel taxonomy to identify and classify clinically relevant decisions (both ac...
