Mycoplasma contamination of cell lines is one of the major problems in cell culture technology. The specific, sensitive, and reliable detection of mycoplasma contamination is an important part of mycoplasma control and should be an established method in every cell culture laboratory. New cell lines as well as cell lines in continuous culture must be tested in regular intervals. The polymerase c...

This paper analyzes investors’ portfolio selection problems in a two-period dynamic model of Knightian uncertainty. We account for the existence of portfolio inertia in this two-period framework. Furthermore, by incorporating investors’ updating behavior, we analyze how new observation in the first period will affect investors’ behavior. By this analysis, we show that new observation in the fir...

The maximum asymptotic bias of an estimator is a global robustness measure of the performance of an estimator. The projection median estimator for multivariate location shows a remarkable behavior regarding asymptotic bias. In this paper we consider a modi cation of the projection median estimator which renders an estimate with better bias performance for point mass contaminations (the worst si...
