Filamentous cyanobacteria such as Anabaena and Nostoc are oxygenic photoautotrophs that grow as trichomes in which some cells can differentiate to become specialized in different functions, producing ...

To explore the feasibility of deriving haploid human ES cells, we generated and analysed a collection of 14 early-passage human pES cell lines for the persistence of haploid cells. We initially used ...

In a previous paper (Lyness and Moler [1]), several closely related formulas of use for obtaining a derivative of an analytic function numerically are derived. Each of these formulas consists of a ...

In this paper, we consider a class of k-step linear multistep methods in the form (1.1) of numerical differentiation (N.D.) formulas. For each k, we have required the property of A-stability which ...
