For most methods, these results did not vary strongly over a wide range of acquisition parameters (number of diffusion weighting directions and b value).
Simulation and phantom-based studies suggest that QBI results are affected by the b-value, the number of diffusion weighting directions, and the signal-to-noise ratio (SNR).
Diffusion weighted images were acquired using a single shot, echo-planar, pulsed gradient spin echo imaging sequence with a b value of 1000 s/mm2 along 32 non-collinear weighting directions (128×128, FOV = 256 mm, TE = 60 ms, TR = 10 sec, 2 mm thickness, 0 mm gap).
Two DWI sets of 30 weighted diffusion scans (b = 1000 s/mm) and 5 × 2 unweighted B0 scans (b = 0 s/mm) were acquired (DWI-MR using parallel imaging SENSE p-reduction 3; high angular gradient set of 30 weighting directions [ Jones 2008], TR = 7035 ms, TE = 68 ms, EPI factor 35; FOV 240 × 240 mm, 2 mm isotropic, 75 slices).
What we see in the majority of the skits is an exploration of the facts of the moving body: weight, leverage, direction.
Later, when Allen dances with just one of the lights, its beam dips and rotates in questioning response to her own subtle shifts of weight and direction.
It is a pleasure, at first, simply to watch her in close quarters: the play of muscles across her bare back, her quick snap into fifth position, her deft shifts of weight and direction.
A sudden burst of acceleration gave Long the extra leverage on his jump, evading both Glen Johnson and Gary Cahill in the process, and the manner in which he beat Joe Hart, applying just the right amount of weight and direction to his header, was impressive in the extreme.
Most studies have been performed on four-wheeled carts and focused on wheel design, handle height, load weight, moving direction, motion phase, and floor type.
In cases where the epistatic interactions were significant for an activity trait and body weight, the direction and magnitude of the four epistatic components for both traits were inspected for potential differences that might indicate differential epistasis.
