Open access

Abstract

Etude analytique du mouvement brownien de rotation d'un ellipsoïde à partir d'une équation établie antérieurement (1). Application au calcul de la dépolarisation, résultant des rotations des molécules excitées pour une fluorescence émise par des molécules ellipsoïdales en solution. Equation aux dérivées partielles du mouvement brownien d'ensemble (rotation et translation) d'un ellipsoïde. Etude de la diffusion de molécules ellipsoïdales dissoutes : anisotropie locale résultant de la diffusion; — existence, pour les faibles gradients de concentration, d'un coefficient de diffusion limite. Formules et graphique donnant les valeurs de ce coefficient de diffusion pour les ellipsoïdes de révolution.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
