| 1 | Probabilistic assessment of tunnel convergence considering spatial variability in rock mass properties using interpolated autocorrelation and response surface method显示文摘This study aims at the probabilistic assessment of tunnel convergence considering the spatial variability in rock mass properties. The method of interpolated autocorrelation combined with finite difference analysis is adopted to model the spatial variability of rock mass properties. An iterative procedure using the first-order reliability method(FORM) and response surface method(RSM) is employed to compute the reliability index and its corresponding design point. The results indicate that the spatial variability considerably affects the computed reliability index. The probability of failure could be noticeably overestimated in the case where the spatial variability is neglected. The vertical scale of fluctuation has a much higher effect on the probabilistic result with respect to the tunnel convergence than the horizontal scale of fluctuation. And the influence of different spacing of control points on the computational accuracy is investigated. | Qing Lü Zhipeng Xiao Jun Zheng Yuequan Shang | 2018 | Geoscience Frontiers2018，9，6： | 12 |
| 2 | Electrochemical performance of La_(2)NiO_(4+δ)-Ce_(0.55)La_(0.45)O_(2−δ)as a promising bifunctional oxygen electrode for reversible solid oxide cells显示文摘In this work,La_(2)NiO_(4+δ)-Ce_(0.55)La_(0.45)O_(2−δ)(denoted as LNO-xLDC)with various LDC contents(x=0,10,20,30,and 40 wt%)were prepared and evaluated as bifunctional oxygen electrodes for reversible solid oxide cells(RSOCs).Compared with the pure LNO,the optimum composition of LNO-30LDC exhibited the lowest polarization resistance(Rp)of 0.53 and 0.12Ω·cm^(2)in air at 650 and 750℃,respectively.The enhanced electrochemical performance of LNO-30LDC oxygen electrode was mainly attributed to the extended triple phase boundary and more oxygen ionic transfer channels.The hydrogen electrode supported single cell with LNO-30LDC oxygen electrode displayed peak power densities of 276,401,and 521 mW·cm^(−2)at 700,750,and 800℃,respectively.Moreover,the electrolysis current density of the single cell demonstrated 526.39 mA·cm^(−2) under 1.5 V at 800℃,and the corresponding hydrogen production rate was 220.03 mL·cm^(−2)·h^(−1).The encouraging results indicated that LNO-30LDC was a promising bifunctional oxygen electrode material for RSOCs. | Pengzhang Li Wei Yang Chuanjin Tian Wenyan Zhao Zhe Lü Zhipeng Xie Chang-An Wang | 2021 | Journal of Advanced Ceramics2021，10，2： | 2 |

| 5 | Pressure-induced robust emission in a zero-dimensional hybrid metal halide (C_(9)NH_(20))_(6)Pb_(3)Br_(12)显示文摘Zero-dimensional(0D)hybrid metal halides are under intensive investigation owing to their unique physical properties,such as the broadband emission from highly localized excitons that is promising for white-emitting lighting.However,fundamental understanding of emission variations and structure–property relationships is still limited.Here,by using pressure processing,we obtain robust exciton emission in 0D(C_(9)NH_(20))_(6)Pb_(3)Br_(12) at room temperature that can survive to 80 GPa,the recorded highest value among all the hybrid metal halides.In situ experimental characterization and first-principles calculations reveal that the pressure-induced emission is mainly caused by the largely suppressed phonon-assisted nonradiative pathway.Lattice compression leads to phonon hardening,which considerably weakens the exciton–phonon interaction and thus enhances the emission.The robust emission is attributed to the unique structure of separated spring-like[Pb_(3)Br_(12)]^(6−)trimers,which leads to the outstanding stability of the optically active inorganic units.Our findings not only reveal abnormally robust emission in a 0D metal halide,but also provide new insight into the design and optimization of local structures of trimers and oligomers in lowdimensional hybrid materials. | Mengting Chen Songhao Guo Kejun Bu Sujin Lee Hui Luo Yiming Wang Bingyan Liu Zhipeng Yan Hongliang Dong Wenge Yang Biwu Ma Xujie Lü | 2021 | Matter and Radiation at Extremes2021，6，5： | 1 |

| 10 | A branching heuristic for SAT solvers based on complete implication graphs显示文摘The performance of modern conflict-driven clause learning(CDCL) SAT solvers strongly depends on branching heuristics. State-of-the-art branching heuristics, such as variable state independent decaying sum(VSIDS) and learning rate branching(LRB), are computed and maintained by aggregating the occurrences of the variables in conflicts. However, these heuristics are not sufficiently accurate at the beginning of the search because they are based on very few conflicts. We propose the distance branching heuristic, which,given a conflict, constructs a complete implication graph and increments the score of a variable considering the longest distance between the variable and the conflict rather than the simple presence of the variable in the graph. We implemented the proposed distance branching heuristic in Maple LCM and Glucose-3.0, two of the best CDCL SAT solvers, and used the resulting solvers to solve instances from the application and crafted tracks of the 2014 and 2016 SAT competitions and the main track of the 2017 SAT competition. The empirical results demonstrate that using the proposed distance branching heuristic in the initialization phase of Maple LCM and Glucose-3.0 solvers improves performance. The Maple LCM solver with the proposed distance branching heuristic in the initialization phase won the main track of the 2017 SAT competition. | Fan XIAO Chu-Min LI Mao LUO Felip MANYA Zhipeng Lü Yu LI | 2019 | Science China(Information Sciences)2019，62，7： | 0 |
| 11 | Ancient DNA reveals the maternal genetic history of East Asian domestic pigs显示文摘Zoo-archaeological and genetic evidence suggest that pigs were domesticated independently in Central China and Eastern Anatolia along with the development of agricultural communities and civilizations.However,the genetic history of domestic pigs,especially in China,has not been fully explored.In this study,we generate 42 complete mitochondrial DNA sequences from~7500-to 2750-year-old individuals from the Yellow River basin.Our results show that the maternal genetic continuity of East Asian domestic pigs dates back to at least the Early to Middle Neolithic.In contrast,the Near Eastern ancestry in European domestic pigs saw a near-complete genomic replacement by the European wild boar.The majority of East Asian domestic pigs share close haplotypes,and the most recent common ancestor of most branches dates back to less than 20,000 years before present,inferred using new substitution rates of whole mitogenomes or combined protein-coding regions.Two major population expansion events of East Asian domestic pigs coincided with changes in climate,widespread adoption of introduced crops,and the development of agrarian societies.These findings add to our understanding of the maternal genetic composition and help to complete the picture of domestic pig evolutionary history in East Asia. | Ming Zhang Yichen Liu Zhipeng Li Peng Lü Jacob D.Gardner Maolin Ye Jihuai Wang Miaomiao Yang Jing Shao Weilin Wang Qingyan Dai Peng Cao Ruowei Yang Feng Liu Xiaotian Feng Lizhao Zhang Enwei Li Yunzheng Shi Zehui Chen Shilun Zhu Weiwei Zhai Tao Deng Ziyuan Duan E.Andrew Bennett Songmei Hu Qiaomei Fu | 2022 | Journal of Genetics and Genomics2022，49，6： | 0 |
