... Reference ID: ACTS . Driver ID: NIST_ACTS . ... This driver supports the NIST Automated Computer Time Service (ACTS). It periodically dials a prespecified telephone number, receives the NIST timecode data and calculates the local clock correction. ... In mode 0 the driver operates continuously at intervals determined by the fudge time1 parameter, as described above. ... Unlike other drivers, each ACTS call generates one clock correction and that correction is processed immediately. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
