| 1 | Dynamic programming methodology for multi-criteria group decision-making under ordinal preferences显示文摘A method of minimizing rankings inconsistency is proposed for a decision-making problem with rankings of alternatives given by multiple decision makers according to multiple criteria. For each criteria, at first, the total inconsistency between the rankings of all alternatives for the group and the ones for every decision maker is defined after the decision maker weights in respect to the criteria are considered. Similarly, the total inconsistency between their final rankings for the group and the ones under every criteria is determined after the criteria weights are taken into account. Then two nonlinear integer programming models minimizing respectively the two total inconsistencies above are developed and then transformed to two dynamic programming models to obtain separately the rankings of all alternatives for the group with respect to each criteria and their final rankings. A supplier selection case illustrated the proposed method, and some discussions on the results verified its effectiveness. This work develops a new measurement of ordinal preferences’ inconsistency in multi-criteria group decision-making (MCGDM) and extends the cook-seiford social selection function to MCGDM considering weights of criteria and decision makers and can obtain unique ranking result. | Wu Li Guanqi Guo Chaoyuan Yue Yong Zhao | 2010 | Journal of Systems Engineering and Electronics2010，21，6： | 3 |
| 2 | 2D materials for conducting holes from grain boundaries in perovskite solar cells显示文摘Grain boundaries in organic-inorganic halide perovskite solar cells(PSCs)have been found to be detrimental to the photovoltaic performance of devices.Here,we develop a unique approach to overcome this problem by modifying the edges of perovskite grain boundaries with flakes of high-mobility two-dimensional(2D)materials via a convenient solution process.A synergistic effect between the 2D flakes and perovskite grain boundaries is observed for the first time,which can significantly enhance the performance of PSCs.We find that the 2D flakes can conduct holes from the grain boundaries to the hole transport layers in PSCs,thereby making hole channels in the grain boundaries of the devices.Hence,2D flakes with high carrier mobilities and short distances to grain boundaries can induce a more pronounced performance enhancement of the devices.This work presents a cost-effective strategy for improving the performance of PSCs by using high-mobility 2D materials. | Peng You Guanqi Tang Jiupeng Cao Dong Shen Tsz-Wai Ng Zafer Hawash Naixiang Wang Chun-Ki Liu Wei Lu Qidong Tai Yabing Qi Chun-Sing Lee Feng Yan | 2021 | Light(Science & Applications)2021，10，4： | 3 |

| 12 | Taxonomic Status of Three Recently Proposed Species of the Genus Kurixalus(Anura,Rhacophoridae),with Discussion on the ZooBank Registrations for Electronical Publication显示文摘In the present study,we propose the synonymization of Kurixalus silvaenaias with Kurixalus qionglaiensis.This conclusion is based on morphological examination and phylogenetic analysis of a series of newly collected specimens,as well as the type series of both nomenclatures.The publication dates of the two species were determined according to the related articles of the International Code of Zoological Nomenclature.Of note,the ZooBank registrations for both species are invalid.Consequently,the publication of K.silvaenaias does not qualify as a published work and the correct publication date of K.qionglaiensis should be the date on which it was physically printed.Furthermore,based on the results presented in this study and its original description,the proposal of K.inexpectatus is deemed untenable and should,therefore,be considered a junior synonym of K.idiootocus.We further provide suggestions for the authors,editors,and publishers who are working on taxonomic publications,as well as for ZooBank to improve the registering service. | Zhitong LYU Maoliang LI Guanqi WANG Gang LIU Min LIU Ke JIANG Dechun JIANG Jiatang LI | 2024 | Asian Herpetological Research2024，15，1： | 0 |
| 13 | Robust watermarking of databases in order-preserving encrypted domain显示文摘Security of databases has always been a hot topic in the field of information security.Privacy protection can be realized by encrypting data,while data copyright can be protected by using digital watermarking technology.By combining these two technologies,a database’s copyright and privacy problems in the cloud can be effectively solved.Based on order-preserving encryption scheme(OPES),circular histogram and digital watermarking technology,this paper proposes a new robust watermarking scheme for protection of databases in the encrypted domain.Firstly,the OPES is used to encrypt data to avoid exposing the data in the cloud.Then,the encrypted data are grouped and modified by the use of a circular histogram for embedding a digital watermark.The common data query operations in database are available for the encrypted watermarking database.In receivers,the digital watermark and the original data can be restored through a secret key and a key table.Experimental results have shown that the proposed algorithm is robust against common database attacks in the encrypted domain. | Shijun XIANG Guanqi RUAN Hao LI Jiayong HE | 2022 | Frontiers of Computer Science2022，16，2： | 0 |
| 14 | High-Density Block Transformation to Increase Natural Ventilation Based on CFD Simulation显示文摘Many countries in the world have experienced extremely rapid urbanization during recent decades. The rapiddevelopment of densely populated areas has produced many urban environmental problems. This researchexplores the relationship between urban morphology and ventilation conditions. Through 3D modeling andComputational Fluid Dynamics (CFD) simulation, we focus on the large scale ventilation of an extended area withseveral buildings. As a testbed, in particular, the core part of Kwun Tong industrial park in Hong Kong is examined, and in order to validate the approach, 10 measurement points are used to get experimental values to be usedfor comparison (such points are located in different positions involving traffic road, pedestrian path and openspace). The error range (±0.7 m/s) indicates that the agreement between field measurement and CFD calculationis good. On the basis of design guidelines and earlier studies, the effective configuration (in terms of building) ofthis area is partially transformed (virtually, i.e., in the numerical simulations) in order to assess the ensuingchanges in terms of wind speed in different locations. This results in a general design and analysis methodologypotentially applicable to other areas. | Siqi Liu Guanqi Huang | 2021 | Fluid Dynamics & Materials Processing2021，17，1： | 0 |

| 16 | Discrete element method study of hysteretic behavior and deformation characteristics of rockfill material under cyclic loading显示文摘Granular geomaterials under different loading conditions manifest various behaviors,such as hysteresis.Understanding their hysteretic behavior and deformation characteristics is the basis for establishing a constitutive relation with excellent performance in deformation prediction.The deformation characteristics of crushable particle materials are analyzed through a series of cyclic loading tests conducted by numerical simulation.The hysteretic behavior is investigated from a particle scale.The increase in particles with contacts less than two may be responsible for the residual strain,and the particle breakage further promotes particle rearrangement and volume contraction.Both the accumulation of plastic strain and the resilient modulus are found to be related to confining pressures,stress levels,cyclic loading amplitudes,and the number of cycles.The plastic strain accumulation can be written as a function of the number of cycles and an evolution function of resilient modulus is proposed. | Mingchun LIN Guanqi WANG Jian ZHOU Wei ZHOU Ni AN Gang MA | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，4： | 0 |

| 18 | Facile Modification on Buried Interface for Highly Efficient and Stable FASn_(0.5)Pb_(0.5)I_(3) Perovskite Solar Cells with NiOx Hole-Transport layers显示文摘Formamidinium(FA)-based Sn-Pb perovskite solar cells(FAPb_(0.5)Sn_(0.5)I_(3) PSCs)with ideal bandgap and impressive thermal stability have caught enormous attention recently.However,it still suffers from the challenge of realizing high efficiency due to the surface imperfections of the transport materials and the energy-level mismatch between functional contacts.Herein,it is demonstrated that the modification on buried interface with alkali metal salts is a viable strategy to alleviate these issues.We systematically investigate the role of three alkali metal bromide salts(NaBr,KBr,CsBr)by burying them between the NiOx hole transport layer(HTL)and the perovskite light-absorbing layer,which can effectively passivate interface defects,improve energy-level matching and release the internal residual strain in perovskite layers.The device with CsBr buffer layer exhibits the best power conversion efficiency(PCE)approaching 20%,which is one of the highest efficiencies for FA-based Sn-Pb PSCs employing NiO_(x) HTLs.Impressively,the long-term storage stability of the unencapsulated device is also greatly boosted.Our work provides an efficient strategy to prepare desired FA-based ideal-bandgap Sn-Pb PSCs which could be applied in tandem solar cells. | Hui Zhang Yuan Zhou Tonghui Guo Xiang Zhang Zhenkun Zhu Junjun Jin Xiaxia Cui Dan Zhang Zhen Wang Lin Li Nai Wang Guanqi Tang Qidong Tai | 2023 | Chinese Journal of Chemistry2023，41，23： | 0 |
| 19 | Effects of inorganic ions,organic particles,blood cells,and cyclic loading on in vitro corrosion of Mg–Al alloys显示文摘Recently,magnesium(Mg)alloys have attracted extensive attention as biodegradable implant materials.However,cyclic loading and the corrosive environment of the body are significant challenges for the practical use of alloys,and there are few studies on this topic.In this study,we conducted a four-point bending fatigue test for 86,400 cycles(12 h)in simulated body fluid(SBF),plasma,and whole blood with an AZ series alloy Mg-9Al-0.5Zn-0.27Mn-0.12Ag,to examine the effects of inorganic ions,organic particles,blood cells,and cyclic loading on Mg alloy corrosion.The Mg^(2+)concentration and solution pH were measured before and after experimentation,and the sample surfaces were characterized by 3D digital microscopy,scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDS),Fourier-transform infrared(FTIR)spectroscopy,Raman spectroscopy,and X-ray photoelectron spectroscopy(XPS).Our results showed that in the non-loading condition,a porous and weak inorganic product layer(mainly Mg/Ca phosphate and carbonate)formed on the surface of the Mg alloy sample immersed in SBF,which hardly had a protective effect on Mg alloy corrosion.For the samples immersed in plasma,the organic particles promoted the formation of an organic and more compact product layer,which protected the Mg alloy from severe corrosion.For the sample immersed in whole blood,the blood cells affected organic particle deposition on the product layer and thus interfered with the formation of an organic compact product layer,which slightly accelerated the corrosion process.Furthermore,cyclic loading damaged the layer integrity and significantly increased the corrosion rates of all the studied materials compared to the samples not subjected to cyclic loading.Nonetheless,under cyclic loading,blood cells adsorbed on the Mg alloy surfaces,and formed films,which protected the Mg alloy substrate and delayed Mg alloy corrosion. | Guanqi Liu Jianmin Han Ying Li Yuzhu Guo Xiaodong Yu Shenpo Yuan Zhihua Nie Chengwen Tan Chuanbin Guo | 2023 | Journal of Magnesium and Alloys2023，11，7： | 0 |
