Efficient estimation of energy transfer efficiency in light-harvesting complexes [PDF]

Physical Review E, 2012
The fundamental physical mechanisms of energy transfer in photosynthetic complexes is not yet fully understood. In particular, the degree of efficiency or sensitivity of these systems for energy transfer is not known given their non-perturbative and non ...

Trophic Transfer Efficiency in Lakes

Ecosystems, 2022
AbstractTrophic transfer efficiency (TTE) is usually calculated as the ratio of production rates between two consecutive trophic levels. Although seemingly simple, TTE estimates from lakes are rare. In our review, we explore the processes and structures that must be understood for a proper lake TTE estimate.
