Instead of measuring economic output -- problematic, goes the new theory, due to tricky exchange rates -- the new approach measures equivalent purchasing power.
However, drawing conclusions about the relationship between quantity and quality of research output is problematic if number of citations is used as the measure of quality because this metric is not independent of our measure of quantity.
This could be used with unparalleled efficiency to enhance sequence output of problematic amplicon libraries.
Unlike SST, which states the residue start and end points of each segment, computing the lengths of secondary structural elements from DSSP and STRIDE's output is problematic and error-prone (Majumdar et al., 2005).
The large variation in yield resulting from differences in the climate, soil conditions or management history and the specifics of individual cultivars render the use of yield data as surrogates for output intensity problematic.
Sole reliance on researchers for key information on research outputs is problematic.
Post-editing of an online output may be problematic or difficult for an individual with a low level of proficiency in the language they are being taught or assessed in as grammatical inaccuracies and awkward phrasing cannot be easily identified and therefore corrected (Niño, 2009).
They are not sport stars or celebrities, and while all are not equally "nourishing," some have particularly problematic output, but, I would argue, they are all more important and vital to us and our community than any celebrity.
Urine was collected as a spot sample for practical reasons, though the interpretation of urinary creatinine levels used for the correction to ≥24 hour urine output may be problematic.
Less constrained output is not only problematic because it is more difficult to predict but also because, in general, it is accompanied by a higher incidence of disfluencies and hesitations.
The 7th and final worker outputs a list of problematic debris as well as the removal order which requires the lowest energy.
