We revisit the shift technique applied to Quasi-Birth and Death (QBD) processes He et al. (2001) [13] in functional form by bringing the attention to the existence and properties of canonical factorizations. To this regard, we prove new results concerning the solutions of the quadratic matrix...
AP Rooney,TJ Ward 摘要: The birth-and-death model of multigene family evolution describes patterns of gene origination, diversification and loss within multigene families. Since it was first developed in the 1990s, the model has been found to characterize a large number of eukaryotic multigene ...

Diagnoses could have been made anytime during the lifetime of the participant's mother (up to the time of death or December 2002), and the same spectrum of diagnoses was included as for the cohort members themselves. We did not study paternal psychiatric family history because, to our ...
