| 1 | Revisiting the security of quantum dialogue and bidirectional quantum secure direct communication显示文摘From the perspective of information theory and cryptography,the security of two quantum dialogue protocols and a bidirectional quantum secure direct communi-cation(QSDC) protocol was analyzed,and it was pointed out that the transmitted information would be partly leaked out in them.That is,any eavesdropper can elicit some information about the secrets from the public annunciations of the legal us-ers.This phenomenon should have been strictly forbidden in a quantum secure communication.In fact,this problem exists in quite a few recent proposals and,therefore,it deserves more research attention in the following related study. | GAO Fei GUO FenZhuo WEN QiaoYan ZHU FuChen | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，5： | 28 |

| 3 | Change of asphaltene and resin properties after catalytic aquathermolysis显示文摘Resin and asphaltene were separated from Liaohe heavy oil. Catalytic aquathermolysis of asphaltene and resin was investigated by using water soluble catalysts (NiSO4 and FeSO4) and oil soluble catalysts (nickel naphthenate and iron naphthenate). Before and after aquathermolysis, the properties of the resin and asphaltene was compared by means of ultimate analysis, vapor pressure osmometer (VPO) average molecular weight, X-ray diffraction (XRD), 13C and 1H nuclear magnetic resonance (NMR). The conversion sequence was as follows: No-catalyst | Yi Yufeng Li Shuyuan Ding Fuchen Yu Hang | 2009 | Petroleum Science2009，6，2： | 12 |

| 5 | Quantum secure direct communication over the collective amplitude damping channel显示文摘An efficient quantum secure direct communication protocol is presented over the amplitude damping channel.The protocol encodes logical bits in two-qubit noiseless states,and so it can function over a quantum channel subjected to collective amplitude damping.The feature of this protocol is that the sender encodes the secret directly on the quantum states,the receiver decodes the secret by performing determinate measurements,and there is no basis mismatch.The transmission's safety is ensured by the nonorthogonality of the noiseless states traveling forward and backward on the quantum channel.Moreover,we construct the efficient quantum circuits to implement channel encoding and information encoding by means of primitive operations in quantum computation. | QIN SuJuan WEN QiaoYan MENG LuoMing ZHU FuChen | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，8： | 9 |
| 6 | Stability of coal pillar in gob-side entry driving under unstable overlying strata and its coupling support control technique显示文摘Considering the situation that it is difficult to control the stability of narrow coal pillar in gob-side entry driving under unstable overlying strata, the finite difference numerical simulation method was adopted to analyze the inner stress distribution and its evolution regularity, as well as the deformation characteristics of narrow coal pillar in gob-side entry driving, in the whole process from entry driving of last working face to the present working face mining. A new method of narrow coal pillar control based on the triune coupling support technique (TCST), which includes that high-strength prestressed thread steel bolt is used to strain the coal on the goaf side, and that short bolt to control the integrity of global displacement zone in coal pillar on the entry side, and that long grouting cable to fix anchor point to constrain the bed separation between global displacement zone and fixed zone, is thereby generated and applied to the field production. The result indicates that after entry excavating along the gob under unstable overlying strata, the supporting structure left on the gob side of narrow coal pillar is basically invalid to maintain the coal-pillar stability, and the large deformation of the pillar on the gob side is evident. Except for the significant dynamic pressure appearing in the coal mining of last working face and overlying strata stabilizing process, the stress variation inside the coal pillar in other stages are rather steady, however, the stress expansion is obvious and the coal pillar continues to deform. Once the gob-side entry driving is completed, a global displacement zone on the entry side appears in the shallow part of the pillar, whereas, a relatively steady fixed zone staying almost still in gob-side entry driving and present working face mining is found in the deep part of the pillar. The application of TCST can not only avoid the failure of pillar supporting structure, but exert the supporting capacity of the bolting structure left in the pillar of last sublevel entry, thus to jointly maintain the stability of coal pillar. | Yuan Zhang Zhijun Wan Fuchen Li Changbing Zhou Bo Zhang Feng Guo Chengtan Zhu | 2013 | International Journal of Mining Science and Technology2013，23，2： | 8 |
| 7 | Comparing the efficiencies of different detect strategies in the ping-pong protocol显示文摘The way to compare the efficiencies of different detect strategies (DSs) in the 'ping-pong' protocol is studied. The trade-off between information gain and dis- turbance is calculated and compared for different DSs. The comparison result primely tallies with our intuitional analysis. It is shown that the analysis of this trade-off is a feasible way to compare the performances of different DSs in theory. | GAO Fei GUO FenZhuo WEN QiaoYan ZHU FuChen | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，12： | 7 |
| 8 | Quantum asymmetric cryptography with symmetric keys显示文摘Based on quantum encryption,we present a new idea for quantum public-key cryptography (QPKC) and construct a whole theoretical framework of a QPKC system. We show that the quantum-mechanical nature renders it feasible and reasonable to use symmetric keys in such a scheme,which is quite different from that in conventional public-key cryptography. The security of our scheme is analyzed and some features are discussed. Furthermore,the state-estimation attack to a prior QPKC scheme is demonstrated. | GAO Fei WEN QiaoYan QIN SuJuan ZHU FuChen | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 6 |

| 10 | Quantum communications with an anonymous receiver显示文摘A new protocol for the anonymous communication of quantum information is proposed. The anonymity of the receiver and the privacy of the quantum information are perfectly protected except with exponentially small probability in this protocol. Furthermore, this protocol uses single photons to construct anonymous entanglement instead of multipartite entangled states, and therefore it reduces quantum resources compared with the pioneering work. | WANG TianYin 1,2* , WEN QianYan 1 & ZHU FuChen 3 1 State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China 2 School of Mathematical Science, Luoyang Normal University, Luoyang 471022, China 3 National Laboratory for Modern Communications, Chengdu 610041, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 5 |
| 11 | Investigation of ZSM-5/MCM-41 Composite Molecular Sieve for Reducing Olefin Content of FCC Gasoline显示文摘ZSM-5/MCM-41 composite molecular sieve was prepared by the nano-assembling method.The ZSM-5 molecular sieve,the MCM-41 molecular sieve,the ZSM-5/MCM-41 mechanical mixture and the ZSM-5/MCM-41 composite molecular sieve were characterized by X-ray powder diffractometry,N2 adsorption isotherms,temperature programmed desorption of ammonia and scanning electron microscopy and their properties were analyzed.Using FCC gasoline as the feed,activities of different molecular sieves for reducing olefin content were investigated in a continuous high-pressure micro-reactor unit under the following conditions:a reaction temperature of 400℃,a reaction time of 2 h,a weight hourly space velocity of 3h-1,and a reaction pressure of 2.0 MPa.The results showed that the HMCM-41 molecular sieve had low reaction performance,and the HZSM-5 molecular sieve demonstrated high aromatization activity,while the ZSM-5/MCM- 41 composite molecular sieve exhibited a best olefin-reducing performance because of its high isomerization activity and moderate aromatization activity.With a largest olefin-reducmg capability and a reasonable distribution of products,the composite molecular sieve was more suitable for FCC gasoline upgrading compared to other three catalysts. | Ji Dekun~(1,2) Li Shuyuan~1 Ding Fuchen~2 Chi Yaoling~2 (1.Chemical Engineering School,China University of Petroleum(Beijing),Beijing 102249 2.Department of Chemical Engineering,Beijing Institute of Petrochemical Technology) | 2009 | China Petroleum Processing & Petrochemical Technology2009，11，4： | 5 |
| 12 | Microstructure and magnetic properties of(SmCo+FeCo)/NdFeB multicomponent nanocomposite magnets fabricated by HPTC with change in heating temperature and composition显示文摘We report the fabrication of bulk anisotropic(SmCo+FeCo)/NdFeB multicomponent nanocomposite magnets using high-pressure thermal compression(HPTC).The correlations among microstructure,magnetic properties,heating temperature and composition of the HPTC nanocomposite magnets were studied.The HPTC magnet made under variable temperatures(VT),with 19 wt% of FeCo phase,exhibits a maximum energy product of 32 MGOe,which is much higher than that(14 MGOe) for the HPTC magnet made under a constant temperature(CT).When the FeCo content increases to^23 wt%,the HPTC magnet made under VT still remains a high energy product of about 25 MGOe.With increasing NdFeB content,the(SmCo+FeCo)/NdFeB multicomponent nanocomposite magnets exhibit an enhanced magnetic anisotropy and coercivity.This work is beneficial to fabricating high-performance and low-cost permanent magnets for practical applications. | Guangwei Huang Li Lou Wenpeng Song Ming Li Fuchen Hou Xiaohong Li | 2020 | Journal of Rare Earths2020，38，7： | 4 |
| 13 | ASB3 knockdown promotes mitochondrial apoptosis via activating the interdependent cleavage of Beclin1 and caspase-8 in hepatocellular carcinoma显示文摘Apoptosis and autophagy are distinct cellular processes that can be highly interconnected. The cross talk between the two processes is indispensable in determining the overall cell fate. Although the apoptosis-promoting effect of caspases has been demonstrated, the roles of autophagy-related proteins and even autophagy itself in regulating apoptosis remain poorly understood. In our present study, we found that downregulation of ubiquitin E3 ligase ASB3 led to enhanced mitochondrial apoptosis as well as autophagy, which synergistically promoted cell death in hepatocellular carcinoma(HCC). We observed the activation of caspase-8 and decrease of autophagy protein Beclin1 in apoptotic cells that were depleted of ASB3. Beclin1 was mainly cleaved by activated caspase-8 and active Beclin1 initiated mitochondrial apoptosis via locating its C-terminal fragment to mitochondria. In addition, knocking down of Beclin1 markedly blocked the apoptosis, indicating its essential role in the process.Notably, our study indicated that enhanced autophagy level might be involved in the activation of caspase-8 and promote the apoptosis. Taken together, our results demonstrated that ASB3 can regulate mitochondrial pathway of apoptosis by controlling caspase-8 mediated cleavage of Beclin1 in HCC. Therefore, ASB3 may potentially serve as a novel target for HCC therapy,especially when combined with autophagy agonist. | Wenli Zhang Fuchen Liu Zhihui Che Mengmeng Wu Zihui Tang Jie Liu Dongqin Yang | 2019 | Science China(Life Sciences)2019，62，12： | 3 |
| 14 | Isolation and Characterization of a Cinnamoyl CoA Reductase Gene(CCR) in Pear(Pyrus pyrifolia)显示文摘Pear is a popular and commercially important fresh fruit, and its texture is related to the presence of sclereid formatted by parenchyma cell with lignification in vascular plants. Previous studies have demonstrated that content of lignin may be regulated by cinnamoyl CoA reductase(CCR) in various plants. However, the function of CCR in pears remains very limited. In the present study, we isolated a cDNA encoding CCR(PpCCR, GenBank accession No. KF999958) and its promoter(proPpCCR) from Whangkeumbae pear to investigate the function of CCR in lignin biosynthesis. PpCCR-GFP expressed in rice mesophyll protoplast demonstrated that PpCCR-GFP was localized in the cytoplasm, indicating that CCR may function in cytoplasm without localization signals. In transgenic plants carrying PpCCR, we observed higher lignin content compared with that in wild type plants, further suggesting that PpCCR can affect the lignin contents through regulating lignin biosynthesis in Arabidopsis thaliana. More studies in other plants are needed to confirm our conclusion. | Meng HU Boya TAN Tao WU Xianming LI Junfan TU Fuchen YANG Hongyan ZHU Zhongqi QIN | 2014 | Agricultural Science & Technology2014，15，6： | 2 |

| 17 | Growth arrest and apoptosis of human hepatocellular carcinoma cells induced by hexamethylene bisacetamide显示文摘AIM: To investigate the cellular effects of hybrid polar compound hexamethylene bisacetamide (HMBA) on the growth and apoptosis of human hepatocellular carcinoma cells and to provide the molecular mechanism for potential application of HMBA in the treatment of liver cancer. METHODS: Effects of HMBA on the growth of human hepatocellular carcinoma SMMC-7721 cells were assayed by MTT chronometry. Apoptosis induced by HMBA was detected by phase-contrast microscopy, flow cytometry, propidium iodide staining and immunocytochemical analysis. RESULTS: The growth of SMMC-7721 cells was significantly inhibited by HMBA, and the growth inhibitory rate was 51.1%, 62.6%, 68.7% and 73.9% respectively after treatment with 5.0, 7.5, 10.0 and 12.5 mmol/L of HMBA. In the cells treated with 10 mmol/L of HMBA for 72 h, the population of cells at sub-G1 phase significantly increased, and the apoptotic bodies and condensed nuclei were detected. Moreover, treatment of SMMC-7721 cells with 10 mmol/L of HMBA down-regulated the expression of Bcl2 anti-apoptotic protein, while slightly up-regulated the level of pro-apoptotic protein Bax. CONCLUSION: Treatment with 10.0 mmol/L of HMBA can significantly inhibit the growth and induce apoptosis of human hepatocellular carcinoma SMMC-7721 cells by decreasing the ratio of Bcl-2 to Bax. | Gao-LiangOuyang Qiu-FengCai MinLiu Rui-ChuanChen ZhiHuang Rui-ShengJiang FuChen Shui-GenHong Shi-DengBao | 2004 | World Journal of Gastroenterology2004，10，7： | 2 |
