The distribution of Pb in contaminated soil was explored by calculating the total Pb and forms of Pb in soil particles with different particle sizes, which has certain reference value for improving heavy metal contaminated soil. Therefore, the objectives of this study are: (1) to compare the ...
Our device uses polarization-gate geometry, allowing pulses at any two wavelengths and unlimited operating bandwidth. The retrieval algorithm is robust and is capable of ignoring most forms of noise in the measured spectrograms.关键词: Ultrafast optics Ultrafast measurements ...
Multilayer evaluation of cardiac contraction is a convenient and fast procedure that can be obtained from basic CMR cine images. Measurement of strain and strain rate must be done cautiously as their range varies amply within the myocardial volume. Sub-endocardial regions and respectively circumferenti...
The sample size calculation was based on the number of participants needed to detect differences in AL elongation of at least 0.15 mm/year among groups [29], with a power of 80% and a significance level of alpha = 0.05. For these calculations, we assumed a measurement SD of 0.15 mm...
