This paper proposes a novel image encryption scheme based on DNA sequence operations and chaotic system. Firstly, two-dimensional logistic chaotic map is employed to modify each pixel of the image, and then, the DNA encoding rules are adopted to encode and generate a DNA matrix. Secondly, pseud...
However, during a seismic event the installed health monitoring system of the bridge would indicate the extent of any possible damage that might be inflicted on the bridge structure and on the FRP composite. A site visit and a judgement by the engineer responsible for the structure would enable...
Moreover, little attention is paid to the highly imbalanced intrinsic structure of the gene expression pattern images, which will significantly compromise the performance of traditional learning algorithms that expect balanced class distributions or equal misclassification costs [13]. In this article, we ...
Experiments and security analysis proved the excellent performance of the algorithm in image encryption as well as against various attacks. Wang et al. [99] suggested another algorithm of color image encryption using alternate chaotic mapping structure. In this study, they exploited the R, G and ...
Compressive sensing is favored because it breaks through the constraints of Nyquist sampling law in signal reconstruction. However, the security defects of joint compression encryption and the problem of low quality of reconstructed image restoration nee
Christian Betzel1 We report the crystal structure of a 40mer mirror-image RNA oligonucleotide completely built from nucleotides of the non-natural L-chirality in complex with the pro-inflammatory chemokine L-CLL2 (monocyte chemoattractant protein-1), a natural protein composed of regular L-amino ...

On the left is an AFM image of DNA nanoarrays bound to their RNA targets at 1500nm x 1500nm scale. The zoom-in images (150nm x 150nm scale) on the right clearly show the barcode (white dots) that identifies the nanoarray and the RNA hybridization signal on 来自 chinese.eurekalert....
