Sentence examples for activation size from inspiring English sources

The overall activation size in image frames was defined as the fraction of activated pixels, expressed as a percentage of the image frame size.

Absolute value of activation: size of circle.

The data in Ref. [ 41] allowed us to deduce that the activation size near the motor cortex evoked by a simple finger-tapping task was about ~2 × 3 cm.

The reconstructed images in Fig. 6 clearly illustrate that DCA-L1 leads to the reconstructed brain activation size more localized and accurate than DCA-L2, with respect to the expected activation region.

However, as the threshold for activation signals as well as activation size can be dynamically altered by the investigator and neither a standardised approach nor a multicentre randomised clinical trial addressing this issue exists, using fMRI to delineate resection borders would in our opinion result in operating under a false sense of security and may even endanger the patient.

The activation sizes determined by various criteria are the most variable measure in this preparation, but adaptive statistical thresholding appears to yield the most stable and reproducible maps.

Additional simulations at different wall shear rates confirmed that all observed phenomena existed at different activation sizes although the specific values of clotting time could change (data not shown).

The impact of activation characteristics (size, intensity and location), study size, physical degradation factors, and reconstruction technique were studied using SPM99 in a group comparison design with correction for multiple comparisons.

The HPSEC profiles by a Waters ultrahydrogel linear column monitored at 206 nm of native and activated TT and group A PS, and the group A PS-TT conjugate, indicated that upon activation, the size of activated TT was unchanged from the native TT with an elution time of 22 minutes, suggesting that little aggregation occurred.

Compared to spin-echo EPI, mHASTE incurs an ∼ 50% reduction in activation cluster size and an ∼ 20% decrease in BOLD contrast.

The studies also show that the activation cluster size in mHASTE increases with the refocusing RF flip angle and TE while decreasing with the echo number (ncenter) used to sample the k-space center.
