Developments in Defining dif.
The Gram-negative soil bacterium Myxococcus xanthus has a complex life cycle that involves vegetative growth and, when nutrients are limiting, formation of spore-containing fruiting bodies. The progression of the developmental cycle depends in part upon the ability of M. xanthus cells to sense and respond to their environment and to coordinate two different motility systems to achieve directed ...
متن کاملHeterogeneous Design in Functional DIF
Dataflow formalisms have provided designers of digital signal processing (DSP) systems with analysis and optimizations for many years. As system complexity increases, designers are relying on more types of dataflow models to describe applications while retaining these implementation benefits. The semantic range of DSP-oriented dataflow models has expanded to cover heterogeneous models and dynam...

متن کاملIndexing dif/2
Many Prolog programs are unnecessarily impure because of inadequate means to express syntactic inequality. While the frequently provided built-in dif/2 is able to correctly describe expected answers, its direct use in programs often leads to overly complex and inefficient definitions — mainly due to the lack of adequate indexing mechanisms. We propose to overcome these problems by using a new p...
متن کاملThe dif/Xer Recombination Systems in Proteobacteria
In E. coli, 10 to 15% of growing bacteria produce dimeric chromosomes during DNA replication. These dimers are resolved by XerC and XerD, two tyrosine recombinases that target the 28-nucleotide motif (dif) associated with the chromosome's replication terminus. In streptococci and lactococci, an alternative system is composed of a unique, Xer-like recombinase (XerS) genetically linked to a dif-l...
