Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

An improved localization method for lesion area in gynecological ultrasound image
EURASIP Journal on Image and Video Processing, 2020 The false positive and false negative rates of current image localization methods in gynecological lesion area are high because the effectiveness is affected by random noise.

Survivin and Aurora Kinase A control cell fate decisions during mitosis
Molecular Oncology, EarlyView.Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

HSI-MSER: Hyperspectral Image Registration Algorithm Based on MSER and SIFT
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Image alignment is an essential task in many applications of hyperspectral remote sensing images. Before any processing, the images must be registered.

View subspaces for indexing and retrieval of 3D models
, 2011 View-based indexing schemes for 3D object retrieval are gaining popularity since they provide good retrieval results. These schemes are coherent with the theory that humans recognize objects based on their 2D appearances.
