Reenement and abstraction are essential operations used in the design of actual systems, real-time or not. We generalize these concepts to sequences of timed actions which are widely used as semantics of real-time behaviors. We obtain two natural, but quite diierent, notions of reenement and abstraction for timed languages depending on whether a timed action is regarded as an action with a dura...

Down-regulation of photosynthesis is among the most common responses observed in C3 plants grown under elevated atmospheric CO2 concentration ([CO2]). Down-regulation is often attributed to an insufficient capacity of sink organs to use or store the increased carbohydrate production that results from the stimulation of photosynthesis by elevated [CO2]. Down-regulation can be accentuated by inad...

This investigation was carried out on two patients suffering from so-called primary subcortical epilepsy. Serial studies were made both of variations in the amount of paroxysmal electrical activity recorded from the brain during the performance of psychological tests and of changes in test performance in the presence of paroxysmal discharges. There is no doubt that changes in the alpha rhythm c...
