The phrase "adjustment exist" is not correct in written English.
It seems to be a grammatical error, as it should be "adjustments exist" or "an adjustment exists" depending on the intended meaning.
Example: "In this context, several adjustments exist that can improve the overall performance of the system."
Alternatives: "adjustments are present" or "an adjustment is available."
We assume that signal transduction has been optimized by evolution, and that concentration adjustment exists to maintain effective signal transmission.
that signal transduction - like many other biological processes - "has been optimized by evolution, and that concentration adjustment exists to maintain effective signal transmission".
Besides the efficiency scores that provide a single index, it is possible to look more precisely on target output levels and the amount of adjustment of output for DMUs.1 Apart from a radial adjustment, there exist as well a second stage shift called slack adjustment (see Appendix).
At this time no specific Rosuvastatin dose adjustment recommendations exist for concurrent administration with Lopinavir/Ritonavir or other protease inhibitors, and until additional efficacy and safety information becomes available, caution should be used with this combination in HIV-infected patients on HAART.
According to Nyrhinen [18] and Müller and Pflug [19], there also exist adjustment coefficient functions for the unidimensional non-Lévy contexts using another approach: let (c_{n}(t)) be the c.g.f. of the aggregate net loss process (aggregate claims minus aggregate premia incomes) at time n, the adjustment coefficient function is given by (c(t)=lim_{nrightarrowinfty}frac {1}{n}c_{n}(t)).
But no legal provision for such adjustments appears to exist.
For instance, the two-step procedure proposed by Taguchi may fail to identify an optimum design condition if an adjustment parameter does not exist, the optimal setting of a design parameter is determined only among the levels included in the parameter design experiment, and, for the dynamic parameter design, the signal parameter is assumed to follow a uniform rather than a general distribution.
This does not, of course, mean that adjustment problems do not exist; of course they do.
In the present investigation, we also found plasma vitamin C positively related with albumin in Spearman correlation analysis, but the association did not exist after adjustment for sex, age, diabetes, mode of dialysis and other confounding effects.
If regional difference in health do exist (after adjustment for socioeconomic factors), we would have expected less favorable health outcomes for those living in underdeveloped regions than in more developed ones.
