Third, the rate of Tm movement would have to exceed 1000 s−1 to not limit the expected rates of myosin recruitment and transitions between Positions C and M. We are encouraged that present measurements do support rapid transitions of Tm in response to myosin binding [42], but additional study is required to establish upper limits of rate.
The study showed the limiting metabolic rates (the upper limit of metabolic rate) were different to each index even in the same environment.
Recent studies of physiological adaptation in aquatic ectotherms indicate that intraspecific thermal tolerance is set by limitations in aerobic performance, specifically the upper limit of heart rate to deliver oxygen to tissues (e.g., [ 15, 22, 23]).
To simulate the percolation processes in paddy fields, a new parameter, the 'potential percolation rate of the paddy field,' was introduced which determines the upper limit of the rate of percolation into the subsoil.
The ability to sample genome sequence of strains that have been highly back-crossed provides an estimate of the upper limit of the rate of spontaneous mutations in sexual reproduction (Baer et al. 2007).
Based on these trials, an acceptable upper limit of perioperative rate for stroke or death has been determined to be around 3% for asymptomatic patients 35 and 6% for patients with symptoms.
This rate is in the upper limit of response rates observed across multiple trials according to a recent meta-analysis that reports overall responses between 45 and 83% [32].
Most recently, and despite the above mentioned consistent national trend, the Dutch Health Care Inspectorate (IGZ) received reports from a significant number of orthopaedic surgery departments, that their rates of SSI after THA/TKA rose to more than 2%, which is presently seen as the acceptable upper limit of SSI-rate for this type of surgery.
In this case, changes that would normally result in vertical shifting could manifest instead as leakage, as the high end of the curve ran into the upper limit of attainable rates while the low end continued to shift up and down.
The denudation rates deduced from A02-ST04, 09, 09, and 13 are less reliable owing to the possibility of later reheating, so the rates are interpreted as the upper limit of the denudation rate in each locality.
A final sensitivity analysis applied an 8.3% annual waning rate, reported by Pellissier et al. as the upper limit of the waning rate [ 15], from the first month following vaccination.
