The second path has substantially higher resistance to DC than the first path, and the superconducting path has substantially higher impedance to AC than the second path.

The cellular signaling pathways comprise a Wnt pathway, an ER pathway, an HH pathway, and/or an AR pathway.

The capacitive path may form a circuitous path with the high impedance path and the low impedance path.

If the selected channel is the one channel that may experience adjacent-channel interference, another channel may be selected from the set.

This would be a port for sea, airport for air and border post for land crossing.

The second way is configurable to either be redundant to the first way or to operate as an associative way independent of the first way.

In the case of route-to-route extrapolation, the respective bioavailability via each route should ideally be taken into consideration.
