—Noise in dynamical systems is usually considered a nuisance. However, in certain nonlinear systems, including electronic circuits and biological sensory systems, the presence of noise can enhance the detection of weak signals. The phenomenon is termed stochastic resonance and is of great interest for electronic instrumentation. We review and investigate(More)
Interim analyses have become an essential part of the monitoring process of clinical trials. Stochastic curtailment has been used in such analyses. This procedure allows for calculation of the probability of rejecting the null hypothesis at the end of a trial given the current data and assuming the null or an alternative hypothesis for the remainder of the(More)
The paper examines several types of anomalously dispersive media that support the argument for superluminal propagation which is the propagation of electromagnetic waves at group velocities exceeding the speed of light. ABSTRACT | This paper reviews earlier studies on superluminal wave propagation in anomalously dispersive media that have been carried out(More)
