Dunque, ribadisco (e son tre!):
Carpinteri e altri [hanno] scientificamente risposto alle poco scientifiche contestazioni che 9 ricercatori INRIM avevano pubblicato per supportare, insieme [all'articolo uscito sul Sole24ore), la raccolta firme contro il piezonucleare".
L'articolo che segue è del 30 giugno scorso, com'è che i 9 ricercatori dell'INRIM capitaneggiati da Amato tacciono?

Amato et al.[arXiv:1205.6418] maintain that certain data published in Carpinteri et al. are not the result of independent measurements, and are in any case affected by uncertainties such that our conclusions are not valid. We will provide clarification regarding the validity of the disputed analyses, showing that they, like the others reported in the original article, are independent and that the uncertainties affecting them in no way invalidate our conclusions.
I. INDEPENDENCE AND RELIABILITY
When the measured percentage of the element is small (<1%), the error is restricted to the third decimal place, corresponding to 1% of the minimum detection limit. In this case, the third decimal place (as in most publications in the field) is not shown, since it is undoubtedly affected by instrumental error. This is the case of Mg and Ti, for which the conclusions made by Amato et al.1 are incorrect. When the measured percentages are in the order of 1%, the second decimal place is a mere guard digit7, since the precision is in the order of 0.01%. Similarly, for a measured percentage of 10%, uncertainty is in the order of 0.1%. In these cases, also the hundreds complement calculation of elements’ concentrations can generate repeated data. For initial measured values that differ in the second decimal place, multiplying by factors, within a certain range, in order to calculate the hundreds complement, may lead to the same final value.
