External single-input single-output sorts can use multiple processors each with a large tournament replacement-selection in memory, and each with private disks to sort an input stream in linear elapsed time. Of course, increased numbers of processors, memories, and disks are required as the input file size grows. This paper analyzes the algorithm and(More)
FastSort is an external sort which uses parallel processing, large main memories and parallel disc accesses to obtain hi~Jh performance. FastSort can sort a file as quickly as it can read the input and it can produce the result as quickly as it can write the target file that 1S it sorts in linear time rather than the traditional Nlog(N) time of serial sort(More)
The occurrence of brain tumors is associated with broad suppression of the immune system function; however, the mechanisms involved in this impairment are not fully characterized. In this study, we have examined mechanisms involved in diminished T lymphocyte reactivity in patients with glioblastomas as compared to patients with other types of brain tumors.(More)
Directed control of intensity of the alpha-rhythm in the somatosensory cortical regions was examined in 20 healthy subjects in conditions of combined (visual and auditory) feedback connection. An attempt has been made to single out by means of control experiments, the factors influencing in such conditions of external stimulation the brain bioelectrical(More)
