Our approach is expository, seeking to put into a general framework seemly disparate results. However, at the end of the paper we do provide some glimpses of new results.

Such watches are known as “PDS” watches. PDS tornado (TOR) watches are issued when the forecaster has high confidence that multiple strong (F2-F3 on the Fujita Scale) or violent tornadoes (F4-F5 on the Fujita Scale) will occur in the watch area, while PDS severe thunderstorm (SEV) watches are issued when there is a threat of a high end “derecho” (e.g. Johns and Hirt 1987, Coniglio et al. 2004) ...

Coronary spasm plays an important role in the pathogenesis of variant angina as well as ischaemic heart diseases. Treatment with vasodilators such as long-acting calcium channel blockers and long-acting nitrates is generally effective in preventing coronary spasm; however, in some patients coronary spasm is refractory to standard therapy. Because of endothelial dysfunction, hyper-reactivity of ...
