Bacteria core RNA polymerase (RNAP) must associate with a sigma factor to recognize promoter sequences. Promoters recognized by the sigma(54) (or sigma(N)) associated RNA polymerase are unique in having conserved positions around -24 and -12 nucleotides upstream from the transcriptional start site. Using DNA microarrays representing the entire Escherichia… (More)
Bacterial flagellar motility and chemotaxis help cells to reach the most favorable environments and to successfully compete with other micro-organisms in response to external stimuli. Escherichia coli is a motile gram-negative bacterium, and the flagellar regulon in E. coli is controlled by a master regulator FlhDC as well as a second regulator,… (More)
This paper deals with the convergence and stability of the semi-implicit Euler method for linear stochastic delay integro-differential equations. It is proved that the semi-implicit Euler method is convergent with strong order p = 0.5. The condition under which the method is asymptotic mean square stable is determined and numerical experiments are presented.
