We survey recent results on the use of trajectories as a tool for modelling language operations and other, related objects. Many applications of the concept of trajectories have been developed since their introduction by Mateescu, Rozenberg and Salomaa in 1996. Areas which have seen activity include the theory of codes, language equations, modelling noisy channels, grammar models and DNA code-w...

Krasner $F^{(m, n)}$-Hyperrings

$!!!!$ In this paper, the notion of fuzzy $!$ Krasner $!(m, n)$-hyperrings($!F^{(m, n)}!$-hyperrings) by using the notion of$F^m$-hyperoperations and $F^n$-operations is introduced and somerelated properties are investigated. In this regards,relationships between Krasner $F^{(m, n)}$-hyperrings and Krasner$(m, n)$-hyperrings are considered. We shall prove that everyKrasner $F^{(m, n)}$-hyperrin...

Major F. W. Cragg

It is with the deepest regret that we learn of the tragic death of Major F. W. Cragg, i.m.s., from typhus fever at Lahore on the 23rd of April, 1924. Major Cragg's death adds another name to the long but brilliant list of scientific investigators who have lost their lives in the prosecution of medical enquiries for the benefit of humanity. He died as truly on active service as did any officer k...

Abnormalities of M egakaryocytes in W / W ” M ice

M ICE OF THE W/WV genotype have hereditary macrycytic anemia,’ and they have defective hematopoietic stem cells that do not proliferate and differentiate normally after transplantation.2’3 The anemia can be corrected by transplantation of functional stem cells into W/WV mice, and splenic tissue from W/W mice supports colony formation by transplanted hematopoietic stem cells in irradiated hosts....
