provided the original work is properly cited. CC Curare, which is the source of modern muscle relaxants, was used for centuries by South American Indians for hunting. On January 23, 1942, Harold R. Griffith and a resident Enid Johnson administered curare (intocostrin) to a patient undergoing an appendectomy, and this was the first clinical use of curare [1]. After World War II, Dr. Cecil Gray a...

We propose new forecast combination schemes for predicting turning points of business cycles. The combination schemes deal with the forecasting performance of a given set of models and possibly providing better turning point predictions. We consider turning point predictions generated by autoregressive (AR) and Markov-Switching AR models, which are commonly used for business cycle analysis. In ...

In the prediction of oscillating time series, the interest is in the turning points of successive oscillations rather than the samples themselves. For this purpose a scheme has been proposed; the state space reconstruction is limited to the turning points and the local (nearest neighbor) model is modified in order to predict the turning point magnitudes and times. This approach is extended here...

Within the epidemic game literature, there is an inconsistency over whether increases in infection risk can discourage prevention practices. In one theory, investments in social distancing and prophylaxis increase monotonely with infection pressure, while in another, there is a turning-point beyond which investments drop off. To-date, the reasons for this difference have been unclear. This arti...
