| 2 | Synthesis and Herbicidal Activity of 1-Phenoxyacetyl-3-arylimidazolidine-2,4-dione Compounds显示文摘In order to find new herbicidal compounds, twelve novel 1-phenoxyacetyl-3-arylimidazolidine-2,4-dione compounds were designed and synthesized by substructure combination strategy using 3-arylimidazolidine-2,4-dione as the intermediate. The structures of the target compounds were confirmed by ~1H NMR and IR. The preliminary bioassay results showed that most of the target compounds had good inhibition against rape and barnyardgrass at the concentration of 100 mg/L. Especially, compound H3 and H5 showed 100% inhibitory activity against rape. | Han Jintao Wang Xiuli Liu Yu Cong Yunbo Dong Wenkai Chai Hongwei Li Xukun | 2018 | Plant Diseases and Pests2018，9，2： | 0 |
| 3 | TPE-H2MWD:an exact thumbnail preserving encryption scheme with hidden Markov model and weighted diffusion显示文摘With the substantial increase in image transmission,the demand for image security is increasing.Noise-like images can be obtained by conventional encryption schemes,and although the security of the images can be guaranteed,the noise-like images cannot be directly previewed and retrieved.Based on the rank-then-encipher method,some researchers have designed a three-pixel exact thumbnail preserving encryption(TPE2)scheme,which can be applied to balance the security and availability of images,but this scheme has low encryption efficiency.In this paper,we introduce an efficient exact thumbnail preserving encryption scheme.First,blocking and bit-plane decomposition operations are performed on the plaintext image.The zigzag scrambling model is used to change the bit positions in the lower four bit planes.Subsequently,an operation is devised to permute the higher four bit planes,which is an extended application of the hidden Markov model.Finally,according to the difference in bit weights in each bit plane,a bit-level weighted diffusion rule is established to generate an encrypted image and still maintain the same sum of pixels within the block.Simulation results show that the proposed scheme improves the encryption efficiency and can guarantee the availability of images while protecting their privacy. | Xiuli CHAI Xiuhui CHEN Yakun MA Fang ZUO Zhihua GAN Yushu ZHANG | 2023 | Frontiers of Information Technology & Electronic Engineering2023，24，8： | 0 |
