Carbonate rock chemical weathering carbon sinks reduce the rate of increase of the atmospheric CO_(2) concentration and global warming. However, uncertainty still exists in the estimation results of carbonate rock chemical weathering carbon sink fluxes(CCSF), and the contributions of climate change and ecological restoration to the CCSF are not clear. To this end, we compiled published site data on ion concentrations in different watersheds in China and used a classical thermodynamic dissolution model to reassess the potential and spatial and temporal patterns of the CCSF in China from 1991 to 2020. We quantified the contributions of temperature(MAT), precipitation(MAP), evapotranspiration(ET), soil water(SM), and the normalized difference vegetation index(NDVI) to the CCSF. The results revealed that(1) China's CCSF was 22.76 t CO_(2)km^(-2)yr^(-1), which was higher than the global average(15.77 t CO_(2)km^(-2)yr^(-1)). The total carbonate rock chemical weathering carbon sink(CCS) was 4772.67×10^(4)t CO_(2), contributing 14.91% of the global CCS through a carbonate rock area of 252.98×10^(4)km^(-2).(2) China's CCSF decreased gradually from southeast to northwest, with values of 33.14, 12.93, and7.27 t CO_(2)km^(-2)yr^(-1)in the southern karst, Qinghai-Tibetan karst, and northern karst regions, respectively.(3) The overall CCSF in China exhibited an increasing trend from 1991 to 2020, with a rate of increase of 0.16 t CO_(2)km^(-2)yr^(-1).(4) The contributions of the MAP, MAT, ET, SM, and NDVI to the CCSF were 63.3%, 3.02%, 27.5%, 3.1%, and 3.05%, respectively. Among them, the increase in precipitation was the main contributor to the increase in the CCSF in China over the last 30 years, while the enhancement of ET offset part of the positive contribution of the increase in precipitation to the CCSF. In conclusion, the results of this study provide a systematic quantification of the magnitude, the patterns, and the influencing factors of CCS over a long time series in

利用有限元软件ABAQUS建立了GH4169合金惯性摩擦焊接二维轴对称有限元模型,模拟过程中多次进行网格重划分以保证其计算精度,并通过分别改变三个工艺参数:转速、压力、转动惯量来分析其对焊接温度场和轴向缩短量的影响。结果表明,适当增加三者数值均使得焊件摩擦界面最高温度逐渐升高,轴向缩短量也变大,但每个参数的影响程度不尽相同,转速对其影响最为明显,压力和转动惯量的影响次之。

A detailed analysis of primal attack and its variants

引用

Science China(Information Sciences) 2022年第3期65卷 182-195页

作者： xue ZHANG Zhongxiang ZHENG xiaoyun WANG Institute for Advanced Study Tsinghua University Key Laboratory of Cryptologic Technology and Information Security Ministry of Education Shandong University

Primal attack is a typically considered strategy to estimate the hardness of cryptosystem based on learning with errors problem（LWE）, it reduces the LWE problem to the unique-SVP by embedding technique and then employs lattice reduction such as BKZ to find the shortest vector. The main reason for the popularity of primal attack is its conservative estimation, in general, the complexity of primal attack is estimated by the hardness of core-SVP as T = 20.292 b. In this work, we first revisit primal attack and give supplemental proof of the scaling factor in Bai-Galbraith embedding, whose value was given according to the experimental results. Then we refine primal attack in two special cases and analyze the variants in detail. One is that, for sparse secret LWE（or sparse secret-error LWE）, primal attack with dropping makes a trade-off between guessing zero components and solving dimension-reduced problems to improve the complexity. The other is that, when TBKZ（b） = poly（d） · TSieve（b） holds in practice, primal attack with preprocessing reduces the time complexity by a factor of 2;–2;through dividing primal attack into three steps and considering them independently.

目的探讨组蛋白去乙酰化酶抑制剂(HDACIs)曲古抑菌素(TSA)对骨肉瘤细胞株MG-63的杀伤作用及机制。方法以不同浓度的TSA作用于体外培养的骨肉瘤细胞,采用MTT法检测细胞生长抑制率;以流式细胞技术(FCM)测不同浓度TSA作用前后骨肉瘤细胞周期变化情况;免疫细胞化学技术观察对Survivin基因和血管内皮生长因子(VEGF)的表达水平;RT-PCR分析TSA作用前后骨肉瘤细胞内P21waf1/cip1mRNA的表达变化。结果 TSA在纳摩尔浓度即可抑制细胞增殖;FCM检测到细胞周期发生改变,G2/M期细胞较对照组增多。免疫组化结果表明,该药能明显抑制Survivin和VEGF蛋白的表达,RT-PCR结果表示TSA能显著诱导P21waf1/cip1mRNA表达。上述结果都有明显的量-效关系。结论 TSA作用于G2/M期并有效诱导体外培养的骨肉瘤细胞凋亡,其诱导凋亡机制之一可能是通过抑制Survivin和VEGF基因的表达并且上调P21蛋白水平实现的。

Clustering for Topological Interference Management

引用

Chinese Journal of Electronics 2022年第5期31卷 844-850页

作者： JIANG xue ZHENG Baoyu WANG Lei HOU xiaoyun Nanjing University of Posts and Telecommunications

To reduce the overhead and complexity of channel state information acquisition in interference alignment, the topological interference management(TIM) was proposed to manage interference, which only relied on the network topology information. The previous research on topological interference management via the low-rank matrix completion approach is known to be NPhard. This paper considers the clustering method for the topological interference management problem, namely,the low-rank matrix completion for TIM is applied within each cluster. Based on the clustering result, we solve the low-rank matrix completion problem via nuclear norm minimization and Frobenius norm minimization *** results demonstrate that the proposed clustering method combined with TIM leads to significant gain on the achievable degrees of freedom.
