The former can be directly ascertained by examining the photovoltaic performance of the DSSC based on a T240/T240-DL-based photoactive layer as shown in Figure 2.
Because of varying samples and data collection strategies, we cannot directly ascertain whether these differences indicate a true decrease in injury rates.
In addition, it allows to directly ascertain the tails of probabilistic distributions, thus facilitating the assessment of rare events and associated risks.
Since neither spatial nor temporal intervals are invariants of spacetime, the invariant spacetime interval \(ds\) cannot be directly ascertained by means of standard clocks and rigid rods.
Because there is no way to directly ascertain the truth of an anticipation before its defined realization time, the knowledge concerning possible futures can be nothing else than well-justified or well-argued beliefs".

Another issue that could make Twitter post data potentially not reliable is that it is difficult to directly ascertain the age of a given Twitter user, and in fact a user may be discussing a disease symptom from a family member who differs in age from the user anyway, but research shows [22] that this is not a deterrent to age-based prediction.
First, since neither spatial nor temporal intervals are invariants of the four-dimensional spacetime of the special theory of relativity and the general theory of relativity, the invariant spacetime interval \(ds\) cannot be directly ascertained by means of standard clocks and rigid rods.
While the temporal reliability of the VOC concentrations could not be directly ascertained here, the parental responses from the two rounds of questionnaires suggest that the home indoor environment has not changed between the baseline and the present investigation.
This additional degree of freedom, which cannot be directly ascertained from experimental peptide binding data, makes epitope prediction for class II MHC more difficult than for class I MHC.
