A comparison with theoretical cross sections is difficult, as all parameters enter in the simulation as well.
However, achieving straight-line motion with a real cantilever beam of circular cross-section is difficult to accomplish.
However, a detailed interpretation that includes the effects of cross-terms is difficult to describe in a written account like this one.
Thus cross-reactivity among mosquito species and other insect antigens may enhance the volatility of this effect on subsequent arbovirus infections within individuals, although the effect of cross-reactivity is difficult to predict and requires further investigation.
At the level of resolution provided by our cross, it is difficult to determine whether such clustering is due to pleiotropy or tight linkage.
Fingers (firmly) crossed, but it is difficult to imagine how this year's fair could end quite so dramatically.
Nadal's cross-court forehand is difficult for anyone to handle, but it is practically Kryptonite for players who rely on a one-handed backhand.
How common or uncommon currently cross-employment is, is difficult to assess.
It is dominated by cross-fracturing which is difficult to identify, but shows a deformed rock mass.
The use of the cross-correlation method is difficult when there is no surface return as shown in Figure 7(a) to 7 d).
In cross section it is difficult to measure, or even identify, a surface deposit; (2) deposits have no discernable vertically definable substructure as opposed to microstratified desert varnish described in the literature [8, 13].
