Seeing a flash of light and having the illusion seem, but only seem, to have in common the property 'when x occurs a flash of light occurs'" (1967, 225).
By contrast, when mutation 'X' occurs first, the pool of single-mutant HSCs is expanded and this ensures that at least some of the progeny remain in cycle thereafter.
We say that there exists an occurrence of x in y, or, more simply, that x occurs in y, when x is a factor of y.
Thus we say that x occurs at the starting position i in y when y[ i.. i+ n−1]= x.
According to David Hume, when we say of two types of object or event that "X causes Y" (e.g., fire causes smoke), we mean that (i) Xs are "constantly conjoined" with Ys, (ii) Ys follow Xs and not vice versa, and (iii) there is a "necessary connection" between Xs and Ys such that whenever an X occurs, a Y must follow.
It has been reported that farnesylation by PFTase occurs when X is alanine, serine, methionine, or glutamine, whereas geranylgeranylation by PGGTase I occurs when X is leucine or phenylalanine.
…1917 for his work on X-ray scattering, which occurs when X-rays pass through a material and are deflected by the atomic electrons.
June 7, 1877 Widnes, England October 23, 1944 Edinburgh, Scotland Charles Glover Barkla, (born June 7 , 1877 Widnes, Lancashire, England died Oct. 23, 1944, Edinburgh, Scotland) British physicist who was awarded the Nobel Prize for Physics in 1917 for his work on X-ray scattering, which occurs when X-rays pass through a material and are deflected by the atomic electrons.
Here the evolutionary process occurs when x ∊ [0,1].
This occurs when x ≥ -ln(f n )/ln (after solving f n τ x = 1).
For example, when n = 1,000, K = 0.1, p = 0.1, τ = 1.1, the mean number of risk alleles per person is 200 and g x > 1 when x > 232, which occurs with frequency 0.009.
