This is supported by research indicating that children with ADHD exhibit increases in the fast frequency component of variability on the SART suggesting a loss of executive functional control, possibly involving the right hemispheric fronto-parietal system, which may then be responsible for deficits in sustained attention [ 38, 39, 57].
The frequency of each variability class on specific positions was mapped on the homology model of PsbO (Fig. 4).
Because the frequency of genetic variability differs among ethnic groups, it cannot be concluded whether the present findings can be extended to people of other races.
Survey respondents were also asked to report their overall perceptions of the frequency of climate variability-induced diseases and health problems in their areas.
They perceived that the frequency of climate variability-induced diseases and health problems had increased because of changes in heat, cold and rainfall events, compared to five to ten years ago (Table 3).
In instructions to the physician evaluators, abnormal temperature patterns were described as "increases in amplitude, changes in frequency, or loss of variability," but no specific numeric criteria were provided.
Finally, due to the multiple tobacco products assessed and the variability in number of products used, frequency of use, and variability in nicotine content across tobacco products, our current analysis of cotinine levels was mainly aimed at examining cotinine levels among current tobacco users versus nonusers, which confirmed differences between users and nonusers.
After excluding invasive blood tests, the results of multivariate logistic regression identified non-invasive assessment (blood pressure, body mass index and very lower frequency of heart rate variability) were the significantly predictors of the risks of metabolic syndrome.
The high frequency and variability of possible complications, the unpredictability of the course of the disease, side effects of medications as well as the often embarrassing nature of symptoms pose particularly high challenges to affected youth, their families and the attending physicians.
The prior distribution models contain information on age-corrected normal threshold values, frequency-of-seeing curves, between-subject variability and inter-point correlations between thresholds [ 16].
