As he goes around kicking tyres, one thing your correspondent has noticed about battery-powered bikes is how many have more positive trail (ie, castor) than one would normally expect.
It has been proven that neither gyroscopic effects nor positive trail are sufficient by themselves or necessary for self-stability, although they certainly can enhance hands-free control.
In traditional bike designs, with a steering axis tilted back from the vertical, positive trail tends to steer the front wheel into the direction of a lean, independent of forward speed.
Of the top 20 negative TRAIL-regulator genes identified in the previous study, only PIP5K1C was identified in our screens, and none of the top 20 positive TRAIL-regulator genes described in the previous report was among the positive regulators our screen identified at relaxed stringency.
Resveratrol plus TRAIL-treated group demonstrated significantly less VEGFR2-positive cells than that of resveratrol or TRAIL treated group.
The walk should be renamed the Positive Ions Trail and marketed as an antidote to urban dwellers who have spent too much time in dry cleaners and sick buildings and copy shops.
This is due to the fact that the R wave is expressed as a strident positive peak trailed by a negative ricochet in the ECG waveform.
Abbreviations and Definitions: MMSE Mini-Mental StatExamination, CVLT California Verbal Learning Test-IIII (16 word list), Recog Recognition, False Pos False Positive Total, Modified Trails Abbreviated trail-making task using numbers and days of the week, BNT-Abbrev Abbreviated (15-item) Boston Naming Test, N/D patient unable to perform, N/A not administered.
As the light pulse travels through the plasma, it pushes negatively charged electrons, creating a region of excess positive ions that trails behind the light.
Other mechanisms generating quorum-like positive feedbacks are trails formation [10], [17], following behavior by fish [18], interactions between individuals in connection with aggregation like processes [19] [21] and imitation by primates [22].
