Background Non-Cartesian parallel imaging is a promising approach for reducing the scan time in multi-slice first-pass myocardial perfusion imaging, allowing increasing volumetric coverage in comparison with standard techniques. Through-time radial GRAPPA has previously been demonstrated for real-time functional cardiac imaging [Seiberlich, et al. MRM 2011 Feb;65 (2):492-505]. In this work, the...
Background Although using more coils may improve parallel imaging performance, it produces a burden on the amount of calibration data required for autocalibrating methods. This work investigates the use of principal component analysis (PCA) to project the original set of coils onto a smaller set of virtual coils to reduce calibration scan time for through-time radial GRAPPA [Seiberlich, et al. ...
In this paper, for the above discrete system of pure-delay type, by improving the former work (2002, J. Math. Anal. Appl. 273, 492-511) which extended the averaged condition offered by S. Ahmad and A. C. Lazer (2000, Nonlinear Analysis 40, 37-49), we offer conditions of persistence, and considering a Lyapunov-like discrete function to the above discrete system, we establish sufficient condition...
The spontaneous utterances produced by 492 Cantonese-speaking children aged 36 to 60 months in 30-minute toy play contexts were collected. The incidence and percentage of different lexical classes, the ratio of noun and verb types and tokens were calculated. A statistically significant predominance of verb usage was found in the expressive utterances of the children. No similar predominance was...
