A very small drift in the scatterometer calibration can be observed over the first few months.. Magnitude of drift is order 0.1 dB. and. preliminary considerations for larger aluminum vessels. Claudio . Montanari. . INFN-Pavia, Italy. 1. ICARUS Meeting - June 16, 2014. Foreword. In view of an increase of sensitive mass for the experiment at FNAL, and considering the extremely high LAr purity achieved with the T600 at LNGS, we are evaluating the possibility to increase the actual maximum drift distance of the T600.. Zach Daniel White. Biology 101h- . Desaix. Why does it matter?. “An antidepressant that brought relief to only seventy percent [of patients] would be a valuable treatment if it did so in one week and had few side effects. Unfortunately, given the current clinical trial methods and placebo-response rates, such an antidepressant, regardless of its true efficiency, would not have more than a fifty percent chance of looking better than placebo.
