A Novel Chaotic Image Encryption Algorithm Based on Latin Square and Random Shift. [PDF]
To realize the safe transmission of images, a chaotic image encryption algorithm based on Latin square and random shift is proposed. The algorithm consists of four parts: key generation, pixel scrambling, pixel replacement, and bit scrambling. Firstly, the key is generated from the plain image to improve the sensitivity of the encryption method ...

Landscape genetic structure of Scirpus mariqueter reveals a putatively adaptive differentiation under strong gene flow in estuaries. [PDF]
In this study, we analyzed the genetic structure of Scirpus mariqueter in the CRE and the QRE and estimated the effects of gene flow, divergent selection, and population colonization history on the structure based on AFLP data. Results showed that there was a moderate‐high level of genetic differentiation among populations, which was tested to be ...
