The neural basis of social perception and understanding. Tjeerd Jellema, Utrecht University. Social scenes usually contain complex stimulus configurations, derived from the postures and actions of one or more agents. A description of the social scene can be made at two successive levels. At the first level, a literal, mechanistic, description is made in terms of causes and consequences of goal-...
متن کاملNew neighbours . I . 13 new companions to nearby M dwarfs ⋆
We present preliminary results of a long-term radialvelocity search for companions to nearby M dwarfs, started in September 95. The observed sample is volume-limited, and defined by the 127 northern (δ > −16◦) M dwarfs listed in the Gliese and Jahreiss (CNS3) catalogue with d≤9 pc and V≤15. Observations are obtained with the ELODIE spectrograph on the 1.93-m telescope of the Observatoire de Hau...
متن کاملEri and GJ 3305 : A 10 − 15 Myr old binary star system at 30 parsecs
Following the suggestion of Zuckerman et al. (2001, ApJ, 562, L87), we consider the evidence that 51 Eri (spectral type F0) and GJ 3305 (M0), historically classified as unrelated main sequence stars in the solar neighborhood, are instead a wide physical binary system and members of the young β Pic moving group (BPMG). The BPMG is the nearest (d . 50 pc) of several groups of young stars with age...

John Baez, Computations and the periodic table By now there is an extensive network of interlocking analogies between physics, topology, logic and computer science, which can be seen most easily by comparing the roles that symmetric monoidal closed categories play in each subject. However, symmetric monoidal categories are just the n = 1, k = 3 entry of a hypothesized ”periodic table” of k-tupl...
متن کاملDiscovery of new nearby L and late - M dwarfs at low Galactic latitude from the DENIS database
We report new nearby L and late-M dwarfs (dphot 6 30 pc) discovered in our search for nearby ultracool dwarfs (I − J > 3.0, later than M8.0) at low Galactic latitude (|b| < 15◦) over 4,800 square degrees in the DENIS database. We used lateM (>M8.0), L, and T dwarfs with accurate trigonometric parallaxes to calibrate the MJ versus I − J colour-luminosity relation. The resulting photometric dista...
