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.
Based on the matrizer technique, indicatrices of the phase vector and phase and group velocities have been firstly constructed in analytical form for TE and TM electromagnetic waves in a monoclinic crystal. A representation has been derived for the energy flux in such an anisotropic medium, and coincidence of the direction of the respective vector with the group velocity direction of the electromagnetic wave is demonstrated.
