A note on the tangle model for DNA recombination
The tangle model developed by Ernst and Sumners provides a rigorous framework to study processive DNA recombination. We suggest here a slight modification of that model. The tangle equations become: ...

Specification of chirality for links and knots
A general scheme has been developed for the assignment of chirality descriptors to chiral links and knots. For oriented links and knots, the new D/L scheme employs linking numbers, self-writhes, and writhe pro...
