But the twin difficulties ahead are muddle and politics.
Mr. Bush faces the twin difficulties of not only including the Democrats but also managing his fellow Republicans.
Wavefront construction in geometrical optics has long faced the twin difficulties of dealing with multi-valued forms and resolution of wavefront surfaces.
In order to get around these twin difficulties, we compared how similar the full set of promoter pairs were to one another using D2z scores.
The best way to confront these twin difficulties must be to maximise the chances of elderly people avoiding cognitive decline and dementia.
Relatives were asked whether the twin had difficulties in memory or thinking and whether these difficulties led to problems in daily activities, to moving into a different type of housing, or to visiting a physician to evaluate the cognitive difficulties.
(Mother 44 of twins) "Any difficulties at home I had (PS) to turn to, she was fantastic, she was reassuring, made good suggestions.
A major problem arises since the potential (101) ( left[10overline{1}right] ) slip system involves the same plane and direction as that proposed for twinning, and so difficulty differentiating between the two might be expected.
The outcome of this study shows that even when only considering large CNVs (>100 kb), there can still be a substantial amount of false positives among the few CN differences between the MZ twins, reflecting the difficulty in measuring CNVs accurately.
Twins were not included because of the difficulty of matching twin pairs in the same neighborhood; across a number of measures, the correlations between twins are higher than those between siblings [ 25, 44].
Other relevant variables were not captured by the WHOGS, such as time between twin deliveries, length and difficulty of labour, labour augmentation practices, indications for ICU admission and newborn laboratory parameters.
