Disclosed are mutant DNA polymerases having improved extension rates relative to a corresponding, unmodified polymerase.

Using the asymmetric MZI in accordance with this disclosure, one can design an algorithm to achieve almost unlimited extinction ration during the switching operation.

The arrangement is such as to allow for the controlled ingress of water into the expandable core (12) which allows for the control of the delay before expansion and the rate of expansion once initiated.

By applying an error correction code only to the lower bit portion, a data transmission method superior in a bit error rate property is provided while suppressing a band expansion rate.

To the south, where the rift is young, extension rates are low and faulting occurs over a wide area.

It provides a figure directly related to the chances of a fire starting, its rate of spread, difficulty of control and the amount of damage it will do.

To the south, where the rift is young, extension rates are low, and faulting occurs over a wide area.
