Area-delay prediction

BAD (Behavioral Area-Delay Predictor) is a fast, comprehensive and integrated area-delay prediction tool which can be used to support behavioral synthesis tools [30]. BAD combines former theoretical and heuristic prediction research done at USC along with new additions around a unified statistical representation model. PERT [34] is selected as the statistical model for initial experimentation. 

The prediction model includes functional, register, multiplexing, wiring and control area and delay predictions. The predictions are based solely on the behavior of the target design, the specific architecture style and area-performance constraints. 

Whether the presence of scar and/or the amount of scar is predictive of SCD is yet to be determined. In a study of 48 patients with CAD who were referred for EP study, infarct size was compared with LVEF, with respect to their correlation with induciblity on EP study (91). They found that patients with sustained, mono-morphic VT had larger infarcts than patients who did not have inducible arrhythmias, and patients with polymorphic VT or VF had intermediate infarct masses. Infarct mass and surface area were better predictors of inducibility of monomorphic VT than LVEF. The study was limited by its small sample size, but demonstrates that scar burden on MRI may correspond to inducibility on EP study. However, while inducibility on EP study is helpful in risk stratification of SCD, as discussed earlier even patients with a negative EP study have a high rate of future SCD. Thus, the true value of delayed enhancement MRI would be to demonstrate risk stratification beyond that of conventional methods. 

In a series of articles that appear periodically in newspapers and magazines, sunken chemical weapons are considered a delayed-action ecological mine of a sort, which will blow up in several months. In fact, if thousands of chemical bombs and shells were simultaneously destroyed owing to corrosion, and hundreds of thousands of tonnes of war contaminants got into the sea water and then into the atmosphere, nobody would remain alive over a vast area. On the other hand, more moderate predictions are published as well. However, in any case, sunken chemical weapons present a real threat for those populations which reside in the Baltic Sea region (about 50 million).
