The phrase "a lifetime expectancy" is not commonly used in written English and may be considered awkward.
It can be used when discussing the expected duration of life, but "life expectancy" is the more standard term.
Example: "The study revealed that the average lifetime expectancy in the region has increased over the past decade."
Alternatives: "life expectancy" or "expected lifespan".
This positive relation implies that butterflies from populations with the highest genetic diversity had a mean lifetime expectancy up to c. 25% higher than butterflies from populations characterised by a low genetic diversity.
Furthermore, P. coridon females with a higher lifetime expectancy will lay more eggs since they lay eggs singly and continually until they die, but need to attain a certain maturity after hatching before being able to lay eggs, and lay fewer eggs in early life compared with later on [ 9].
At AU$12,405 per life year gained and an average lifetime expectancy of 16.084 years, five-yearly colonoscopy screening was the most cost-effective strategy.
However, in Part II [2], we claimed that in case the frequency of access to objects is known, it is possible to calculate the expected lifetime expectancy of individual objects in a collection, if their current DP and pH are also known.
Demographic data were used to estimate population size, effective population connectivity (number of successful dispersal events) and a fitness component, lifetime expectancy.
A positive correlation between genetic diversity and mean lifetime expectancy was detected at a very local scale in a metapopulation consisting of large high-density populations interconnected by considerable dispersal rates.
The controls were significantly younger than the CH patients, and there were more men in the patient group, but as genotype is a constant trait, and not associated with reduced lifetime expectancy or to a specific gender, this is irrelevant for our analysis.
In NeuT mice an IL-12-adjuvanted allogeneic HER2/neu-expressing cell vaccine, repeatedly administered, was found to delay mammary cancer onset, leading to a more than doubled mice lifetime expectancy [ 2, 3].
Lower genetic diversity was coupled to a sharp decrease in adult lifetime expectancy (LTE): P. coridon butterflies of some populations lived for up to 25% (2.4 days) longer on average than their counterparts of other populations, therefore significantly increasing their individual fitness.
Ion engines could reach even further into space, as engineers use a genetic algorithm to suggest a grid design that could double lifetime expectancy.
