| 2 | Study on Titanium Alloy TC4 Ballistic Penetration Resistance Part I:Ballistic Impact Tests显示文摘Ballistic impact test of different-scale casings is an efficient way to demonstrate the casing containment capability at the preliminary design stage of the engine. For the sake of studying the titanium alloy TC4 casing performance, the ballistic tests of flat and curved simulation casing are implemented by using two flat blades of different sizes as the projectile. The impact mechanism and failure of the target are discussed. Impact of the projectile is a highly nonlinear transient process with the large deformation of the target. On the impact, failures of the flat casing and the subscale casing are similar, concluding two parts, the global dishing and localized ductile tearing. The main localized failure mode combines plugging (shear) and petaling (shear) if the projectile perforates or penetrates, while crater (shear) if the projectile rebounds. The ballistic limit equation is verified by the test data and the results show that this empirical equation could be a practical way to estimate the critical velocity. | ZHANG Tao CHEN Wei GUAN Yupu GAO Deping | 2012 | Chinese Journal of Aeronautics2012，25，3： | 10 |
| 3 | Lattice-based linearly homomorphic signature scheme over binary field显示文摘To design an efcient post-quantum linearly homomorphic signature scheme,using the pre-image sampling function,a lattice-based linearly homomorphic signature scheme over a binary feld is proposed in this paper.Linear homomorphism is achieved through the homomorphism of the lattice-based hash function used in the proposed signature scheme.It is shown that the proposed scheme satisfes the privacy property.Based on the hardness of the short integer solution problem,the proposed scheme is unforgeable against the type 1 and type 2adversaries in the random oracle model.Moreover,compared with a presented linearly homomorphic signature scheme in 2011,the proposed scheme has some advantages with respect to the public key size,signature length and computational cost. | WANG FengHe HU YuPu WANG BaoCang | 2013 | Science China(Information Sciences)2013，56，11： | 9 |

| 8 | Sustainable development of coal cities in Heilongjiang province based on AHP method显示文摘The sustainable development of coal mining cities in Heilongjiang province has important effect on the economic stability and development of Heilongjiang, Northeast China, and China at large. To further the sustainable development evaluation system of coal mining cities in Heilongjiang province, based on the analytic hierarchy process (AHP) method combined with operational and scientific principles using Saaty's 1-9 scale method to construct the judgment matrix from five aspects, such as economic development and environmental quality, this paper establishes the comprehensive evaluation index system of sustainable development of coal mining cities in Heilongjiang province, including comprehensive index of industrial economic benefits and the contribution rate of science and technology. In addition, using fuzzy comprehensive evaluation method, a comprehensive evaluation is made on the indices of the four major coal mining cities of Heilongjiang. The result shows that the coal mining cities are not better than Datong of Shanxi province in many indices. The economic development and environment quality are the most important indices of the targeted layer influencing the sustainable development of coal mining cities of Heilongjiang, and their index weights are 0.4358 and 0.2844, respectively. These two indices including comprehensive index of industrial economic benefit and the ratio of environmental protection investment to GDP are the key elements influencing the two aspects. | Zhang Yupu Sun Yongbo Qin Jiangbo | 2012 | International Journal of Mining Science and Technology2012，22，1： | 7 |
| 9 | Study on ballistic penetration resistance of titanium alloy TC4, Part II: Numerical analysis显示文摘Enhancing containment capability and reducing weight are always great concerns in the design of casings. Ballistic tests can help to mitigate a catastrophic event after a blade out, yet taking time and costing money. A wise way is to hunt for a validated numerical simulation technology, through which the material dynamic behavior over the strain rate range in the ballistic tests should be represented and reasonable failure strain should be defined. The simulation results show that the validation of the numerical simulation technology based on the test data can accurately estimate the absorption energy, describe the physical process and failure mode during the penetration, as well as the failure mechanism. It is found that energy dissipation of projectiles is in manner of compression stage, energy conversion stage, and interactive scrap stage. An effect indicator is proposed, where the factors of critical velocity including impact orientation and mass of projectiles and thickness of casings are considered. The critical velocity presents a linear relation with the effect indicator, which implies the critical velocity obtained by the flat casing could underestimate the capability of the real casing. | Zhang Tao Chen Wei Guan Yupu Gao Deping Li Shuguang | 2013 | Chinese Journal of Aeronautics2013，26，3： | 6 |
| 10 | Certificateless Sequential Aggregate Signature Scheme on NTRU Lattice显示文摘Having the advantages of certificateless signature and the aggregate signature at the same time,certificateless aggregate signature has been widely applied in e-business, e-government and software security since it was proposed in 2007. Although a number of certificateless aggregate signature schemes have been proposed, all of them are based on the classic number theory problem,which are no longer secure in the quantum era. In this paper, a certificateless sequential aggregate signature over number theory research unit lattice is proposed, which is proven to be secure in random oracle model. Moreover,we extend the new scheme into an efficient certificatebased sequential aggregate signature which is also secure in quantum era. | XIE Jia HU Yupu GAO Juntao JIANG Mingming | 2019 | Chinese Journal of Electronics2019，28，2： | 6 |
| 11 | Induction of jasmonic acid biosynthetic genes inhibits Arabidopsis growth in response to low boron显示文摘The essential micronutrient boron(B) has key roles in cell wall integrity and B deficiency inhibits plant growth. The role of jasmonic acid(JA) in plant growth inhibition under B deficiency remains unclear. Here,we report that low B elevates JA biosynthesis in Arabidopsis thaliana by inducing the expression of JA biosynthesis genes. Treatment with JA inhibited plant growth and, a JA biosynthesis inhibitor enhanced plant growth, indicating that the JA induced by B deficiency affects plant growth. Furthermore,examination of the JA signaling mutants jasmonate resistant1, coronatine insensitive1-2, and myc2 showed that JA signaling negatively regulates plant growth under B deficiency. We identified a low-B responsive transcription factor, ERF018, and used yeast one-hybrid assays and transient activation assays in Nicotiana benthamiana leaf cells to demonstrate that ERF018 activates the expression of JA biosynthesis genes. ERF018 overexpression(OE)lines displayed stunted growth and up-regulation of JA biosynthesis genes under normal B conditions,compared to Col-0 and the difference between ERF018 OE lines and Col-0 diminished under low B.These results suggest that ERF018 enhances JA biosynthesis and thus negatively regulates plant growth. Taken together, our results highlight the importance of JA in the effect of low B on plant growth. | Yupu Huang Sheliang Wang Chuang Wang Guangda Ding Hongmei Cai Lei Shi Fangsen Xu | 2021 | Journal of Integrative Plant Biology2021，63，5： | 5 |
| 12 | Effect of Freeze-thaw Cycles on Bond Strength between Steel Bars and Concrete显示文摘The effect of freezing and thawing cycles on mechanical properties of concrete(compressive, splitting tensile strength)was experimentally investigated.According to the pullout test data of three kinds of deformed steel bars,the bond stress-slip curves after freezing and thawing were obtained.The empirical equations of peak bond strength were proposed that the damage accounted for effects of freezing and thawing cycle.Meanwhile,the mechanism of bond deterioration between steel bars and concrete after freezing and thawing cycles was discussed.All these conclusions will be useful to the durability design and reliability calculation of RC structures in cold region. | JI Xiaodong SONG Yupu LIU Yuan | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，4： | 5 |
| 13 | Efficient and Provably Secure Multi-Recipient Signcryption from Bilinear Pairings显示文摘Signcryption is a cryptographic primitive that performs signature and encryption simultaneously, at lower computational costs and communication overheads than the signature-then- en- cryption approach. In this paper, we propose an efficient multi-recipient signcryption scheme based on the bilinear pairings, which broadcasts a message to multiple users in a secure and au- thenticated manner. We prove its semantic security and unforge- ability under the Gap Diffie-Hellman problem assumption in the random oracle model. The proposed scheme is more efficient than re-signcrypting a message n times using a signcryption scheme in terms of computational costs and communication overheads. | LI Fagen HU Yupu LIU Shuanggen | 2007 | Wuhan University Journal of Natural Sciences2007，12，1： | 5 |

| 15 | Controllable synthesis of highly crystallized mesoporous TiO2/WO3 heterojunctions for acetone gas sensing显示文摘Mesoporous semiconducting metal oxides(SMOs)heterojunctions are appealing sensors for gas detecting.However,due to the different hydrolysis and condensation mechanism of every metal precursor and the contradiction between high crystallinity and high surface area,the synthesis of mesoporous SMOs heterojunctions with highly o rdered mesostructures,highly crystallized frameworks,and high surface area remains a huge challenge.In this work,we develop a novel'acid-base pair'adjusted solvent evaporation induced self-assembly(EISA)strategy to prepare highly crystallized ordered mesoporous TiO2/WO3(OM-TiO2/WO3)heterojunctions.The WCl6 and titanium isopropoxide(TIPO)are used as the precursors,respectively,which function as the'acid-base pair',enabling the coassembly with the structure directing agent(PEO-b-PS)into highly ordered meso structures.In addition,PEO-b-PS can be converted to rigid carbon which can protect the meso structures from collapse during the crystallization process.The resultant OM-TiO2/WO3 heterojunctions possess primitive cubic mesostructures,large pore size(~21.1 nm),highly crystalline frameworks and surface area(~98 m2/g).As a sensor for acetone,the obtained OM-TiO2/WO3 show excellent re sponse/recovery perfo rmance(3 s/5 s),good linear dependence,repeatability,selectivity,and long-term stability(35 days). | Changyao Wang Yuhui Li Pengpeng Qiu Linlin Duan Wei Bi Yan Chen Dingyi Guo Yupu Liu Wei Luo Yonghui Deng | 2020 | Chinese Chemical Letters2020，31，5： | 4 |

| 17 | Efficient Ring Signature Scheme Without Random Oracle from Lattices显示文摘Among post-quantum alternatives, latticebased cryptography is the most promising one, due to its simple operations, reduction from aver-age-case to worstcase hardness, and supporting of rich functionalities. Ring signature enables a user to sign anonymously on behalf of an adaptively chosen group, and has multiple applications in anonymous e-voting, anonymous authentication, whistle blowing etc. However, most lattice-based ring signature schemes were constructed in the random oracle model from lattice basis delegation and they suffer large verification key sizes as a common disadvantage. This work proposes an efficient ring signature scheme from lattice basis delegation without random oracle based on the extended split-SIS problem, whose security is approximately as hard as the worst-case SIVP problem. Our scheme is proved to be anonymous and existentially unforgeable under latticebased assumptions. Finally, the verification key size is significantly reduced to a small constant, instead of increasing linearly with the number of ring members. | GAO Wen HU Yupu WANG Baocang CHEN Jiangshan WANG Xin | 2019 | Chinese Journal of Electronics2019，28，2： | 4 |
| 18 | An Attribute-Based Signature Scheme from Lattice Assumption显示文摘Inspired by the framework of Boyen, in this paper, an attribute-based signature(ABS) scheme from lattice assumption is proposed. In this attribute-based signature scheme, an entity's attributes set corresponds to the concatenation of a lattice matrix with the sum of some random matrices, and the signature vector is generated by using the Preimage Sampling algorithm. Compared with current attribute-based signature schemes, this scheme can resist quantum attacks and enjoy shorter public-key, smaller signature size and higher efficiency. | ZHANG Yanhua HU Yupu JIANG Mingming | 2015 | Wuhan University Journal of Natural Sciences2015，20，3： | 4 |
| 19 | Lattice-based sequential aggregate signatures with lazy verification显示文摘This paper proposes the first lattice-based sequential aggregate signature(SAS) scheme with lazy verification that is provably secure in the random oracle model. As opposed to large integer factoring and discrete logarithm based systems, the security of the construction relies on worst-case lattice problem, namely, under the small integer solution(SIS) assumption. Generally speaking, SAS schemes enable any group of signers ordered in a chain to sequentially combine their signatures such that the size of the aggregate signature is much smaller than the total size of all individual signatures. Unlike prior such proposals, the new scheme does not require a signer to retrieve the keys of other signers and verify the aggregate-so-far before adding its own signature, and the signer can add its own signature to an unverified aggregate and forward it along immediately, postponing verification until load permits or the necessary public keys are obtained. Indeed, the new scheme does not even require a signer to know the public keys of other signers. | Zhang Yanhua Hu Yupu Jiang Mingming Xue Lili | 2015 | The Journal of China Universities of Posts and Telecommunications2015，22，6： | 3 |
| 20 | Double Batch for RLWE-Based Leveled Fully Homomorphic Encryption显示文摘To further improve the efficiency of Fully homomorphic encryption(FHE), a leveled FHE scheme based on the Ring learning with errors(RLWE) problem is put forward by simultaneously applying both batch techniques available. Our scheme therefore allows double packing many plaintext values into each ciphertext to support single-instruction-multiple-data-type operations, which effectively reduces the ciphertext expansion ratio. An efficient evolutionary method for achieving arbitrary homomorphic permutation operations on a packed ciphertext is also provided by using several given key-switching hints.Further, a few new operations are introduced, with which not only to describe the key switching process in our batch setting clearly, but also to analyze the noise growth conveniently. | CHEN Hu HU Yupu LIAN Zhizhu | 2015 | Chinese Journal of Electronics2015，24，3： | 3 |
