The SPaCIFY project, which aims at bringing advances in MDE to the satellite flight software industry, advocates a top-down approach built on a domain-specific modeling language named Synoptic. In line with previous approaches to real-time modeling such as Statecharts and Simulink, Synoptic features hierarchical decomposition of application and control modules in synchronous block diagrams and ...

Morphologic observations on early retinal synaptogenesis of Macaca mulatta fetuses of known gestational ages are described. Attempt is made to correlate the first appearance of synoptic vesicles, lamellar material, and the establishment of presynaptic contacts in both the inner and outer plexiform layers and in both types of synapses developing in these zones. Possible origin of lamellar materi...
