| 3 | Adakite-type sodium-rich rocks in Awulale Mountain of west Tianshan:Significance for the vertical growth of continental crust显示文摘The sodium-rich dacites and albite porphyries of Permian in the Awulale Mountain of west Tianshan have unique chemical and trace element signatures identical to adakite. These intermediate-acidic igneous rocks are characterized by high Na2O, Al2O3 and Sr contents and high Sr/Y and La/Y ratios (>40 and >20, respectively), and low Y and Yb contents, and strong depletion in HREE, and positive Eu anomaly. The (143Nd/144Nd)i is in the range from0.51236 to 0.51248 and the εNd(t) is positive value (+0.79-+3.11); the (87Sr/86Sr)i is in the range from 0.7052 to 0.7054. These Nd and Sr isotopic composition features indicate that the source rocks of these adakite-type rocks are from a weakly depleted mantle, or a depleted mantle, but was contaminated by the crustal materials. These adakite-type rocks were most likely derived from the partial melting of new underplated basaltic rocks under the conditions of amphibo-lite to eclogite transition in the postcollisional environment of North Xinjiang during the Permian | XIONG Xiaolin ZHAO Zhenhua BAI Zhenghua MEI Houjun WANG Yixian WANG Qiang XU Jifeng Niu Hecai BAO Zhiwei | 2001 | Chinese Science Bulletin2001，46，10： | 25 |
| 4 | Geochemistry of Alkali-rich Igneous Rocks of Northern Xinjiang and Its Implications for Geodynamics显示文摘Five nearly E-W-trending alkali-rich igneous rock belts are distributed from north to south in northern Xinjiang, and they are composed mainly of riebeckite, K-feldspar granite and high-K and medium-K calc-alkaline volcanic rocks and shoshonite. They were mainly emplaced or erupted between the Carboniferous and Permian. The compositions of Sr, Nd, Pb, and O isotopes imply that their principal resource materials are derived from the upper mantle or juvenile crust, indicating obvious continental growth in the Phanerozoic. The trace element association implies that their tectonic settings are within plate and volcanic arc for alkali-rich granites, and post-collisional arc, late oceanic arc and continental arc for alkali-rich volcanic rocks. An archipelago model was suggested for the tectonic evolution in northern Xinjiang. It can be named the central-Asia-type orogeny, which is different from the so called circum-Pacific ocean-continent-type tectonics or the Alpine-Himalayan | ZHAO Zhenhua BAI Zhenghua XIONG Xiaolin MEI Houjun WANG Yixian | 2000 | Acta Geologica Sinica(English Edition)2000，74，2： | 16 |

| 6 | EABDS: Attribute-Based Secure Data Sharing with Efficient Revocation in Cloud Computing显示文摘Ciphertext-policy attribute-based encryption(CP-ABE) is becoming a promising solution to guarantee data security in cloud computing. In this paper,we present an attribute-based secure data sharing scheme with Efficient revocation(EABDS) in cloud computing.Our scheme first encrypts data with Data encryption key(DEK) using symmetric encryption and then encrypts DEK based on CP-ABE, which guarantees the data confidentiality and achieves fine-grained access control. In order to solve the key escrow problem in current attribute based data sharing schemes, our scheme adopts additively homomorphic encryption to generate attribute secret keys of users by attribute authority in cooperation with key server, which prevents attribute authority from accessing the data by generating attribute secret keys alone.Our scheme presents an immediate attribute revocation method that achieves both forward and backward security.The computation overhead of user is also reduced by delegating most of the decryption operations to the key server.The security and performance analysis results show that our scheme is more secure and efficient. | HUANG Qinlong MA Zhaofeng YANG Yixian FU Jingyi NIU Xinxin | 2015 | Chinese Journal of Electronics2015，24，4： | 8 |
| 7 | The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |
| 8 | Novel way to research nonlinear feedback shift register显示文摘In this paper,we regard the nonlinear feedback shift register(NLFSR)as a special Boolean network,and use semi-tensor product of matrices and matrix expression of logic to convert the dynamic equations of NLFSR into an equivalent algebraic equation.Based on them,we propose some novel and generalized techniques to study NLFSR.First,a general method is presented to solve an open problem of how to obtain the properties(the number of fixed points and the cycles with different lengths)of the state sequences produced by a given NLFSR,i.e.,the analysis of a given NLFSR.We then show how to construct all 22n-(l-n)/22n-lshortest n-stage feedback shift registers(nFSR)and at least 22n-(l-n)-1/22n-l-1shortest n-stage nonlinear feedback shift registers(nNLFSR)which can output a given nonperiodic/periodic sequence with length l.Besides,we propose two novel cycles joining algorithms for the construction of full-length nNLFSR.Finally,two algorithms are presented to construct 22n-2-1different full-length nNLFSRs,respectively. | ZHAO DaWei PENG HaiPeng LI LiXiang HUI SiLi YANG YiXian | 2014 | Science China(Information Sciences)2014，57，9： | 7 |
| 9 | Soil erosion and sediment interception by check dams in a watershed for an extreme rainstorm on the Loess Plateau,China显示文摘The magnitude of soil erosion and sediment load reduction efficiency of check dams under extreme rainstorms is a long-standing concern.The current paper aims to use check dams to deduce the amount of soil erosion under extreme rainstorms in a watershed and to identify the difference in sediment interception efficiency of different types of check dams.Based on the sediment deposition at 12 check dams with 100% sediment interception efficiency and sub-catchment clustering by taking 12 damcontrolled catchments as clustering criteria,the amount of soil erosion resulting from an extreme rainstorm event on July 26,2017(named '7·26' extreme rainstorm) was estimated in the Chabagou watershed in the hill and gully region of the Loess Plateau.The differences in the sediment interception efficiency among the check dams in the watershed were analyzed according to field observations at 17 check dams.The results show that the average erosion intensity under the '7-26' extreme rainstorm was approximately 2.03×10~4 t/km^2,which was 5 times that in the second largest erosive rainfall in 2017(4.15×10~3 t/km^2) and 11-384 times that for storms in 2018(0.53×10~2 t/km^2-1.81×10~3 t/km^2).Under the '7-26' extreme rainstorm,the amount of soil erosion in the Chabagou watershed above the Caoping hydrological station was 4.20 × 106 t.The sediment interception efficiency of the check dams with drainage canals(including the destroyed check dams) and with drainage culverts was 6.48 and 39.49%,respectively.The total actual sediment amount trapped by the check dams was 1.11 × 106 t,accounting for 26.36% of the total amount of soil erosion.In contrast,3.09×106 t of sediment were input to the downstream channel,and the sediment deposition in the channel was 2.23×10~6 t,accounting for 53.15%of the total amount of soil erosion.The amount of sediment transport at the hydrological station was8.60×10~5 t.The Sediment Delivery Ratio(SDR) under the '7·26' extreme rainstorm was 0.21.The results indicated that the amount of soil erosion was huge,and the sediment interception efficiency of the check dams was greatly reduced under extreme rainstorms.It is necessary to strengthen the management and construction technology standards of check dams to improve the sediment interception efficiency and flood safety in the watershed. | Leichao Bai Nan Wang Juying Jiao Yixian Chen Bingzhe Tang Haolin Wang Yulan Chen Xiqin Yan Zhijie Wang | 2020 | International Journal of Sediment Research2020，35，4： | 7 |

| 11 | Quantum proxy signature scheme with public verifiability显示文摘In recent years, with the development of quantum cryptography, quantum signature has also made great achievement. However,the effectiveness of all the quantum signature schemes reported in the literature can only be verified by a designated person.Therefore, its wide applications are limited. For solving this problem, a new quantum proxy signature scheme using EPR quantumentanglement state and unitary transformation to generate proxy signature is presented. Proxy signer announces his public key whenhe generates the final signature. According to the property of unitary transformation and quantum one-way function, everyone canverify whether the signature is effective or not by the public key. So the quantum proxy signature scheme in our paper can be publicverified. The quantum key distribution and one-time pad encryption algorithm guarantee the unconditional security of this scheme.Analysis results show that this new scheme satisfies strong non-counterfeit and strong non-disavowal. | ZHOU JingXian ZHOU YaJian NIU XinXin YANG YiXian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，10： | 6 |
| 12 | High-efficiency quantum steganography based on the tensor product of Bell states显示文摘In this paper,we first propose a hidden rule among the secure message,the initial tensor product of two Bell states and the final tensor product when respectively applying local unitary transformations to the first particle of the two initial Bell states,and then present a high-efficiency quantum steganography protocol under the control of the hidden rule.In the proposed quantum steganography scheme,a hidden channel is established to transfer a secret message within any quantum secure direct communication(QSDC) scheme that is based on 2-level quantum states and unitary transformations.The secret message hiding/unhiding process is linked with the QSDC process only by unitary transformations.To accurately describe the capacity of a steganography scheme,a quantitative measure,named embedding efficiency,is introduced in this paper.The performance analysis shows that the proposed steganography scheme achieves a high efficiency as well as a good imperceptibility.Moreover,it is shown that this scheme can resist all serious attacks including the intercept-resend attack,measurement-resend attack,auxiliary particle attack and even the Denial of Service attack.To improve the efficiency of the proposed scheme,the hidden rule is extended based on the tensor product of multiple Bell states. | XU ShuJiang CHEN XiuBo NIU XinXin YANG YiXian | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，9： | 6 |
| 13 | Compressive Sensing-Based Audio Semi-fragile Zero-Watermarking Algorithm显示文摘A novel compressive sensing-based audio semi-fragile zero-watermarking algorithm is proposed in this paper. This algorithm transforms the original audio signal into the wavelet domain and applies compressive sensing theory to the approximation wavelet coefficients.The zero-watermarking is constructed according to the positive and negative properties of elements in the measurement vector. The experimental results show that the proposed algorithm is robust against common audio signal processing and fragile to malicious tampering. Compared with the existing algorithms, the proposed algorithm improves malicious tampering detection accuracy in common audio signal processing environments. | TANG Xin MA Zhaofeng NIU Xinxin YANG Yixian | 2015 | Chinese Journal of Electronics2015，24，3： | 5 |
| 14 | Focal mechanism analysis and parameter estimation of Zhangbei-Shangyi earthquake from differential SAR inter-ferometry显示文摘On 10 January, 1998 an earthquake of Ms=6.2 occurred in the Zhangbei-Shangyi region of North China. The surface seismic deformation was measured in the previous study using the 3 pass ERS-1/2 SAR differential inter-ferometric technology (D-INSAR). In this note the focal mechanism of Zhangbei-Shangyi earthquake is estimated from the D-INSAR measurement of surface deformation based on a standard elastic dislocation model for seismic displacement. The inversion procedure is an iterative, linear least-squares algorithm. Through the relation between the focal parameters and displacement in the line of sight direc-tion measured in the radar interferogram, the optimum focal parameter set is derived. The results show that the seismic fault of Zhangbei-Shangyi earthquake is a thrust fault dip-ping SW with a large right-lateral displacement component. The strike and dip are 95°and 30°respectively on a fault patch of 12 km long by 14 km wide. Its hypocenter is located at N40°58’, E114°21’, and 7.5 km in depth. | ZHANG Hong WANG Chao SHAN Xinjian MA Jin TANG Yixian QUO Ziqi | 2002 | Chinese Science Bulletin2002，47，4： | 5 |

| 16 | Quantum network coding for multi-unicast problem based on 2D and 3D cluster states显示文摘We mainly consider quantum multi-unicast problem over directed acyclic network, where each source wishes to transmit an independent message to its target via bottleneck channel. Taking the advantage of global entanglement state 2D and 3D cluster states, these problems can be solved efficiently. At first, a universal scheme for the generation of resource states among distant communication nodes is provided. The corresponding between cluster and bigraph leads to a constant temporal resource cost. Furthermore, a new approach based on stabilizer formalism to analyze the solvability of several underlying quantum multi-unicast networks is presented. It is found that the solvability closely depends on the choice of stabilizer generators for a given cluster state. And then, with the designed measurement basis and parallel measurement on intermediate nodes, we propose optimal protocols for these multi-unicast sessions. Also, the analysis reveals that the resource consumption involving spatial resources, operational resources and temporal resources mostly reach the lower bounds. | Jing LI Xiubo CHEN Xingming SUN Zongpeng LI Yixian YANG | 2016 | Science China(Information Sciences)2016，59，4： | 4 |
| 17 | Preparation and Characterization of Palladium Colloidal Nanoparticles by Thermal Decomposition of Palladium Acetate with Microwave Irradiation显示文摘A series of solvent-stabilized palladium colloidal nanoparticles were prepared via thermal decomposition of palladium acetate methylisobutylketone (MIBK) solution in the presence of alkali and alcohol with microwave irradiation. The colloidal nanoparticles were characterized with TEM, XPS and XRD. The average diameters of nanoparticles increase from 30 to 40 nm with the increase in concentration of palladium acetate. TEM and XRD observation demonstrated that the palladium colloidal nanoparticles were clusters agglomerated from hundreds of smaller palladium crystallines with size of 3~4 nm. The influence of the concentrations of alkali and alcohol to the particle size was also discussed. | Yixian CHEN, Baolin HE and Hanfan LIU Hubei Key Laboratory for Catalysis and Material Science, University of South-Central for Nationalities, Wuhan 430074, China PCLCC, State Key Laboratory of Polymer Physics and Chemistry, Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080, China | 2005 | Journal of Materials Science & Technology2005，21，2： | 4 |
| 18 | Conjugate adjoining problem in braid groups and new design of braid-based signatures显示文摘The development of quantum computation casts serious threats to the securities of most existing public-key cryptosystems. Braid-based cryptography is one of the alternatives that have potential advantages in resisting quantum attacks. In this paper, the state of the art of braid cryptography is surveyed, and then a new cryptographic problem-conjugate adjoining problem related to braid groups is proposed. Based on this problem, we design a new braid-based signature scheme. This scheme is efficient and provably secure in the random oracle model. Further, we present the comparison between braid-based signatures and RSA-based ones. The signing process of the braid-based schemes is more efficient than that of RSA-based ones, while the verifying process of the braid-based ones is observably slow. Hence, braid-based signatures are suitable for scenarios where the signing process has to be as quick as possible but delays are permitted in the verifying process, for example, in off-line e-cash systems. The key sizes in braid-based schemes are considerably large-about 2K bits in the case of secret keys and 12K bits in the case of public keys. However, braid operations are much simpler and more efficient than modular exponential operations. Therefore, braid-based schemes can be embedded into devices with low computational ability and large memory space. The capability of braid cryptosystems to resist currently known quantum attacks is also discussed from the perspective of hidden subgroup problems. | WANG LiCheng WANG LiHua CAO ZhenFu YANG YiXian NIU XinXin | 2010 | Science China(Information Sciences)2010，53，3： | 3 |
| 19 | NAMPT-targeting PROTAC promotes antitumor immunity via suppressing myeloid-derived suppressor cell expansion显示文摘Nicotinamide phosphoribosyl transferase(NAMPT) is considered as a promising target for cancer therapy given its critical engagement in cancer metabolism and inflammation.However,therapeutic benefit of NAMPT enzymatic inhibitors appears very limited,likely due to the failure to intervene nonenzymatic functions of NAMPT.Herein,we show that NAMPT dampens antitumor immunity by promoting the expansion of tumor infiltrating myeloid derived suppressive cells(MDSCs) via a mechanism independent of its enzymatic activity.Using proteolysis-targeting chimera(PROTAC) technology,PROTAC A7 is identified as a potent and selective degrader of NAMPT,which degrades intracellular NAMPT(iNAMPT) via the ubiquitin-proteasome system,and in turn decreases the secretion of extracellular NAMPT(eNAMPT),the major player of the non-enzymatic activity of NAMPT.In vivo,PROTAC A7 efficiently degrades NAMPT,inhibits tumor infiltrating MDSCs,and boosts antitumor efficacy.Of note,the anticancer activity of PROTAC A7 is superior to NAMPT enzymatic inhibitors that fail to achieve the same impact on MDSCs.Together,our findings uncover the new role of enzymatically-independent function of NAMPT in remodeling the immunosuppressive tumor microenvironment,and reports the first NAMPT PROTAC A7 that is able to block the pro-tumor function of both iNAMPT and eNAMPT,pointing out a new direction for the development of NAMPT-targeted therapies. | Ying Wu Congying Pu Yixian Fu Guoqiang Dong Min Huang Chunquan Sheng | 2022 | Acta Pharmaceutica Sinica B2022，12，6： | 3 |
