We calculate crossing probabilities and one-sided last exit time densities for a class of moving barriers on an interval [0, T ] via Schwartz distributions. We derive crossing probabilities and first hitting time densities for another class of barriers on [0, T ] by proving a Schwartz distribution version of the method of images. Analytic expressions for crossing probabilities and related densi...

I am honored to present this lecture in tribute to Nancy L. Schwartz. I did not know Professor Schwartz well, yet I am aware of her important professional contributions. First and foremost are the direct advances to the profession made through her writings. But also her indirect contributions, as a teacher and an intellectual leader, are very important. Some of the ideas and applications discus...

The role of alcohol as the precipitating factor in the induction of acute attacks of acute intermittent porphyria was studied in an Indian population. Thirty-four teetotal patients with acute intermittent porphyria, in remission, were given 60 ml of 30% ethanol. Except for two patients, all had negative Watson-Schwartz tests prior to the alcohol. Within 24 hours, the Watson-Schwartz test became...
