| 1 | Construction of MDS block diffusion matrices for block ciphers and hash functions显示文摘Dear editor,Block ciphers are one of the most important building blocks in many cryptosystems.Modern block ciphers are often iterations with several rounds,where each round comprises a(nonlinear)confusion layer and a(linear)diffusion layer.The diffusion layer plays a significant role in block | Ruoxin ZHAO Rui ZHANG Yongqiang LI Baofeng WU | 2016 | Science China(Information Sciences)2016，59，9： | 3 |
| 2 | Protecting white-box cryptographic implementations with obfuscated round boundaries显示文摘Dear editor,White-box cryptography aims to give a secure software implementation of the cryptographic algorithm running in an untrusted environment which is owned and controlled by an adversary.Its major goal is to protect the confidentiality of the secret key.Given the increasing demands for softwareonly applications,white-box cryptography has received a lot of attention from industry.By now。 | Tao XU Chuankun WU Feng LIU Ruoxin ZHAO | 2018 | Science China(Information Sciences)2018，61，3： | 1 |
| 3 | Variations in the substrate composition and microbial community structure in the anaerobic fermentation process using the green algae Enteromorpha prolifera显示文摘Enteromorpha prolifera is a nutrient-rich green alga and abound in the Yellow Sea and the Bohai Sea of China. In this study, E. prolifera was anaerobically digested for biogas production. The variations of chemical compositions and microbial community structure as well as the physical structure of E. prolifera in anaerobic digestion process were investigated. This is the first report of multiple ways to deeply analysis the process of E. prolifera anaerobic digestion. Results from the present work showed that the biogas obtained from E. prolifera anaerobic digestion could achieve 409.7 mL•g− 1 TS with an average methane concentration of 53.2%, and the VFAs content in substrate played a vital role for driving the biogas production of flora. Moreover, S1 of Thermotogaceae and Cenarchaeum, the dominant bac-teria and archaea in digestion flora, respectively, played important roles in degrading E. prolifera, acidizing slurry, and providing methanogenic substrate for methanogens. | Chao Ai Aijun Tong Jiahui Wen Ruoxin Chen Yajun Huang Chao Zhao | 2022 | Food Production, Processing and Nutrition2022，4，1： | 0 |
| 4 | Disturbed sensitive equilibrium led by stress-induced inflammation in psychiatric illness显示文摘INTRODUCTION The internal environment of an organism is in dynamicequilibrium homeostasis,butabnormal conditions can shift certain equilibrium parameters,resulting in a stress response.Inflammation is triggered by noxious stimuli and involves the transmission of vascular cells and immune cells,coordinated by a large number of mediators forming a complex regulatorynetwork with basic pathways consisting of inducers,sensors,mediators and effectors. | Hanqing Zhao Ruoxin Jin Ji Hu | 2022 | General Psychiatry2022，35，6： | 0 |
| 5 | Effectively Modulating Oxygen Vacancies in Flower‑Likeδ‑MnO_(2)Nanostructures for Large Capacity and High‑Rate Zinc‑Ion Storage显示文摘In recent years,manganese-based oxides as an advanced class of cathode materials for zinc-ion batteries(ZIBs)have attracted a great deal of attentions from numerous researchers.However,their slow reaction kinetics,limited active sites and poor electrical conductivity inevitably give rise to the severe performance degradation.To solve these problems,herein,we introduce abundant oxygen vacancies into the flower-likeδ-MnO_(2)nanostructure and effectively modulate the vacancy defects to reach the optimal level(δ-MnO_(2)-x-2.0).The smart design intrinsically tunes the electronic structure,guarantees ion chemisorption-desorption equilibrium and increases the electroactive sites,which not only effectively accelerates charge transfer rate during reaction processes,but also endows more redox reactions,as verified by first-principle calculations.These merits can help the fabricatedδ-MnO_(2)-x-2.0 cathode to present a large specific capacity of 551.8 mAh g^(-1) at 0.5 A g^(-1),high-rate capability of 262.2 mAh g^(-1) at 10 A g^(-1) and an excellent cycle lifespan(83%of capacity retention after 1500 cycles),which is far superior to those of the other metal compound cathodes.In addition,the charge/discharge mechanism of theδ-MnO_(2)-x-2.0 cathode has also been elaborated through ex situ techniques.This work opens up a new pathway for constructing the next-generation high-performance ZIBs cathode materials. | Yiwei Wang Yuxiao Zhang Ge Gao Yawen Fan Ruoxin Wang Jie Feng Lina Yang Alan Meng Jian Zhao Zhenjiang Li | 2023 | Nano-Micro Letters2023，15，12： | 0 |
