(In fact, I think most of the standard economic models probably under- estimate real costs because they assume efficient policies (e.g., a carbon tax coupled with a well-designed technology investment program).
A large Purcell factor always implies photoluminescence enhancement (assuming efficient out-coupling of light) since the excited state can relax faster radiatively.
Single-copy loci cannot simultaneously transcribe sense and antisense RNA (Hobson et al., 2012) so, although such a locus can give rise to a mixed population of sense and antisense RNA in the cytoplasm over time, in the vicinity of the transcription site only one sense of RNA should ever be present, assuming efficient RNA export.
We have assumed that efficient vector control means there is no transmission in the home patch and all people are equally likely to travel from the home patch to the destination patch.
This bump may disappear if coagulation is more efficient than assumed here: more efficient coagulation may be realized if tgrow ≫ 30 Myr and/or coagulation also occurs in denser regions (Subsection 4.2).
Yes, you might be saying, it might be technically possible to fly 73,000 miles in the first eight days of January, assuming very efficient long-haul connections — but you'd have to be up in the air nearly all of that time, with almost no margin left for work.
A radical departure in design, the parafoil, a soft airplane-wing shape with no rigid members, used by the skydiver as a parachute, assumes its efficient flying profile entirely from the wind's inflating the air channels along the leading edge.
The dynamics in place to arrive at a fixed allocation percentage at a certain stage of life assumes an efficient and normal market at the time.
Nonlocal transport models of irrigation generally assume perfectly efficient flushing of burrows, that is Cb = C0 (eqn. (3), (6).
