Range migration compensation for moving targets in chirp radars with stepped frequency
The Journal of Engineering, 2019 Long-time coherent pulse integration method has been extensively used in detecting weak targets, but the detection performance is affected by range migration (RM) due to high radial velocity.

Principles of MicroRNA–Target Recognition
PLoS Biology, 2005 MicroRNAs (miRNAs) are short non-coding RNAs that regulate gene expression in plants and animals. Although their biological importance has become clear, how they recognize and regulate target genes remains less well understood. Here, we systematically evaluate the minimal requirements for functional miRNA-target duplexes in vivo and distinguish classes
