It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Nonlinear model of single-walled nanotube geometrically nonlinear oscillations is derived. The Sanders-Koiter nonlinear shell theory accounting nonlocal elasticity is basis of this model. The system of the partially differential equations of the nanotube nonlinear oscillations is obtained. The system of nonlinear ordinary differential equations for the nanotube oscillations is derived using Galerkin technique. The backbone curves of free nonlinear oscillations are calculated.
