A two-tone method for measuring the residual phase noise (RPN) of microwave optical links (MOLs) and individual components in the MOL is proposed in this paper. Compared with the previous RPN measurement methods, the two-tone correlation-based method suppresses the noise contributions of the uncorrelated noise sources except that of the device under test (DUT). By this method, the RPN of externally...
We compared the utility of two 25-OH-D immunoassays to a liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for assessing human serum samples from the Chinese population.In total, 451 Chinese serum samples were tested using the IDS 25-Hydroxy Vitamin D EIA kits and the LC–MS/MS 25-OH-D method. Of these, 239 samples were also analysed using DiaSorin 25-Hydroxyvitamin D RIA kits.The regression...

Objective: To study the expression of angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2) and the angiopoietin receptor (Tie-2) in colorectal cancer tissue, and analyze the correlation between their expression levels in colorectal cancer tissue and the histological differentiation of colorectal cancer; and to discuss their roles in the progression of colorectal cancer to provide new targets for the clinical...
Track-to-track fusion is widely used by large-scale distributed surveillance systems to integrate multisensor tracking data. A critical step prior to track-to-track fusion is track-to-track assignment. However, when ground targets are tracked by airborne sensors, the target tracks contain not only tracking sensor errors but also navigation errors of the sensor platforms. If the errors are not compensated...
Compressed sensing is a technique for efficiently sampling signals which are sparse in some transform domain. Recently, the idea of compressed sensing has been used in the radar system. When the number of targets on the range-Doppler plane is small, the target scene can be reconstructed by employing the compressed sensing techniques. In this paper, we extend this idea to the MIMO radar. In the MIMO...
