Investigation into Polyurethane at Varying Dose Rates of Ionizing Radiation for Clinical Application
Many animal-pollinated plant species have been introduced to non-native regions without their usual pollinators. Nevertheless, some of these alien species managed to establish reproducing naturalized populations, which might negatively affect native plants. Recent studies have shown that many naturalized alien species can readily attract native pollinators. However, it is not known whether alie...
We analyze the accuracy of four methods for measuring e ective bandwidths (EBs). We also seek to point out advantages and drawbacks of the four estimators. We nd that for nite time realizations of a process the measured e ective bandwidth di ers considerably from its analytical counterpart. We also show that increasing the trace length has little impact on the accuracy of the measurements. We e...
We analyze the effects of founding conditions on the survival of new firms. We allow the effects of founding conditions to be transitory and estimate how long such effects last. Our findings indicate that founding effects are important determinants of exit rates. Moreover, in most cases, their effect on survival seems to persist without much of an attenuation for several years after the foundin...
