Transfer efficiency is a key parameter describing ecosystem structure and function used to estimate fisheries production; however, it also one of the most uncertain parameters. Questions remain about how habitats, food resources, fishing pressure, spatiotemporal scales, as well temperature, primary production, other climate drivers impact transfer efficiency. Direct measurements are difficult, ...

The limits of polarization transfer efficiency are explored for systems consisting of three isotropically coupled spins 1/2 in the absence of relaxation. An idealized free evolution and control Hamiltonian is studied, which provides an upper limit of transfer efficiency (in terms of transfer amplitude and transfer time) for realistic homonuclear spin systems with arbitrary Heisenberg-type coupl...
