| 1 | Construction and enumeration of Boolean functions with maximum algebraic immunity显示文摘Algebraic immunity is a new cryptographic criterion proposed against algebraic attacks. In order to resist algebraic attacks, Boolean functions used in many stream ciphers should possess high algebraic immunity. This paper presents two main results to find balanced Boolean functions with maximum algebraic immunity. Through swapping the values of two bits, and then generalizing the result to swap some pairs of bits of the symmetric Boolean function constructed by Dalai, a new class of Boolean functions with maximum algebraic immunity are constructed. Enumeration of such functions is also given. For a given function p(x) with deg(p(x)) < n2 , we give a method to construct functions in the form p(x)+q(x) which achieve the maximum algebraic immunity, where every term with nonzero coefficient in the ANF of q(x) has degree no less than n2 . | ZHANG WenYing WU ChuanKun LIU XiangZhong | 2009 | Science in China(Series F)2009，52，1： | 4 |
| 2 | Identification of abnormal conditions in high-dimensional chemical process based on feature selection and deep learning显示文摘Identification of abnormal conditions is essential in the chemical process.With the rapid development of artificial intelligence technology,deep learning has attracted a lot of attention as a promising fault identification method in chemical process recently.In the high-dimensional data identification using deep neural networks,problems such as insufficient data and missing data,measurement noise,redundant variables,and high coupling of data are often encountered.To tackle these problems,a feature based deep belief networks(DBN)method is proposed in this paper.First,a generative adversarial network(GAN)is used to reconstruct the random and non-random missing data of chemical process.Second,the feature variables are selected by Spearman’s rank correlation coefficient(SRCC)from high-dimensional data to eliminate the noise and redundant variables and,as a consequence,compress data dimension of chemical process.Finally,the feature filtered data is deeply abstracted,learned and tuned by DBN for multi-case fault identification.The application in the Tennessee Eastman(TE)process demonstrates the fast convergence and high accuracy of this proposal in identifying abnormal conditions for chemical process,compared with the traditional fault identification algorithms. | Wende Tian Zijian Liu Lening Li Shifa Zhang Chuankun Li | 2020 | Chinese Journal of Chemical Engineering2020，28，7： | 3 |
| 3 | Estimating interaction between surface water and groundwater in a permafrost region of the northern Tibetan Plateau using heat tracing method显示文摘Understanding the interaction between groundwater and surface water in permafrost regions is essential to study flood frequencies and river water quality, especially in the high latitude/altitude basins. The application of heat tracing method,based on oscillating streambed temperature signals, is a promising geophysical method for identifying and quantifying the interaction between groundwater and surface water. Analytical analysis based on a one-dimensional convective-conductive heat transport equation combined with the fiber-optic distributed temperature sensing method was applied on a streambed of a mountainous permafrost region in the Yeniugou Basin, located in the upper Heihe River on the northern Tibetan Plateau. The results indicated that low connectivity existed between the stream and groundwater in permafrost regions.The interaction between surface water and groundwater increased with the thawing of the active layer. This study demonstrates that the heat tracing method can be applied to study surface water-groundwater interaction over temporal and spatial scales in permafrost regions. | TanGuang Gao Jie Liu TingJun Zhang ShiChang Kang ChuanKun Liu ShuFa Wang Mika Sillanpaa YuLan Zhang | 2020 | Research in Cold and Arid Regions2020，12，2： | 1 |

| 8 | Highly selective oxidation of amines to imines by Mn2O3 catalyst under eco-friendly conditions显示文摘Enhancing the selectivity of imines for the oxidative self-coupling of primary amines was found to be challenging in the heterogeneous catalysis.Three different manganese oxides(M-3,M-4,M-5) were synthesized by controlling the calcination temperature using a simple template-free oxalate route.The prepared manganese oxides were systematically characterized using XRD,N2 sorption,SEM,TEM,XPS,H2-TPR techniques.M-4 gave 96.2% selectivity of imine at 100% conversion of benzylamine,which was far more superior than other existing protocols.Mn^3+/Mn^4+ ratio was found to affect the selectivity of the imines.The probable reaction pathway for amines oxidation catalyzed by manganese oxides was proposed for the first time. | Fushan Chen Tao Yang Songlin Zhao Taotao Jiang Lu Yu Houfeng Xiong Chuankun Guo Yufang Rao Yan Liu Liu Liu Jian Zhou Pengxiang Tu Jun Ni Qunfeng Zhang Xiaonian Li | 2019 | Chinese Chemical Letters2019，30，12： | 1 |

| 11 | Recent advances in multifunctional metal-organic frameworks for lithium metal batteries显示文摘In view of novel materials in the field of lithium metal batteries(LMBs), metal-organic frameworks(MOFs) have attracted extensive research interest owing to their controllable pore size, unsaturated metal sites and multifunctional organic groups. A variety of MOFs have been elaborately calculated and synthesized to be applied as separator coating, electrolyte modulators and solid-state electrolyte fillers in LMBs. In this mini-review, we summarize the mechanism of MOFs to limit the migration of anions, improve the Li-ion transference number and prolong the lifespan of LMBs. Suitable pore structure of MOFs can physically restrict the movement of Li^(+). Unsaturated metal sites can adsorb anions by electrostatic interaction. In addition,multifunctional organic functional groups that limit the migration of anions are discussed. Finally, the key challenges and perspectives in the development direction of MOFs-based separators and electrolytes are further elaborated. | Jiaqi Li Zheng Weng Zuosu Qin Ying Zhang Ning Zhang Xiaohe Liu Chuankun Jia Gen Chen Jiang Zhou | 2024 | Science China Chemistry2024，67，3： | 0 |
| 12 | Optimized Method for Real-time Texture Reconstruction with RGB-D Camera显示文摘With the appearance of RGB-D camera, the field of three-dimensional(3D) reconstruction receives more and more attention. In this paper, we present an optimization approach to produce high-quality textured 3D models based on the real-time 3D reconstruction system.The resulting models of real-time texture reconstruction often suffer from blurring, ghosting, and other artifacts.Our approach addresses this texture quality problem using blur detection and an optimized weight function. Experimental results demonstrate that our approach can improve the quality of textured 3D models by reducing the blur and ghosts on the model surface. | Yonghong Hou Hang Li Chuankun Liu Liang Zhang | 2017 | Transactions of Tianjin University2017，23，5： | 0 |
