The authors present their initial results with the hemizona assay (HZA), which was developed to predict the fertilizing potential of spermatozoa. The HZA uses the matching halves of a human zona pellucida from a nonfertilizable and nonliving oocyte, providing an internal control on zona-to-zona variability. Maximal binding of human sperm to the hemizona(More)
A new technique for the management of control structures in distributed implementations of dynamic process systems is presented. Instead of storing the runtime stacks of parallel processes as linked lists of function blocks in a heap structure, the local stacks of several parallel processes, which are executed on the same processor element, are stored in an(More)
