Nous étendons les notions de processus croissants associés à un processus au cas des processus à paramètre bidimensionnel : existence et égalité de limites de sommes de carrés d’accroissements (conditionnés ou non) sur des rectangles, sur des segments parallèles, ou mixtes.
Many protein sequences present non trivial periodicities, such as cysteine signatures and leucine heptads. These known periodicities probably represent a small percentage of the total number of sequences periodic structures, and it is useful to have general tools to detect such sequences and their period in large databases of sequences. We compare three statistics adapted from those used in time series analysis: a generalisation of the simple autocovariance based on a similarity score and two statistics...
