1Patterns and driving factors of WUE and NUE in natural forest ecosystems along the North-South Transect of Eastern China显示文摘从 2008 年 7 月,到 2008 年 8 月,从 22 种类的 72 件叶样品和在九天赋的 81 件土壤样品,森林生态系统对沿着东方中国(NSTEC ) 的纵贯的横断的南方镇定,从北方。把样品基于这些,我们学习了蔬菜水使用效率(WUE ) 和氮使用效率(NUE ) 的地理分发模式,并且分析了他们与环境因素的关系。蔬菜 WUE 和 NUE 分别地通过叶的 13C 的测量和占优势的种类的 C/N 被计算。结果出现了:(1 ) 蔬菜 WUE,从 2.13 ~ 28.67 mg C g1 H2O ,当蔬菜 NUE 显示出一个相反的趋势时,沿着 NSTEC 在代表性的森林生态系统从南方线性地增加了到北方,从北方增加到南方,从 12.92 ~ 29.60 g C g1 N 。(2 ) 蔬菜 WUE 和 NUE 被气候主导地驾驶并且显著地由土壤营养素因素影响。基于集中为 WUE 的 75.5% 变化正在回答的多重逐步的回归分析,吝啬的年度温度,土壤磷集中,和土壤氮(p < 0.001 ) 。当时,吝啬的年度降水和土壤磷集中能在蔬菜 NUE 解释 65.7% 变化(p < 0.001 ) 。而且,蔬菜 WUE 和 NUE 将被大气的氮免职严重也在氮影响浸透的生态系统。(3 ) 在沿着 NSTEC 的典型森林生态系统在蔬菜 WUE 和 NUE 之间有一种重要交易关系(p < 0.001 ) ,沿着 NSTEC 在自然森林生态系统在资源利用为植被显示平衡策略。这研究建议那个全球变化将影响森林生态系统的资源使用效率。然而,当减少时,植被能由增加缺乏资源的使用效率适应那些变化相对宽大的。但是极端影响例如重氮免职,将打破这交易机制并且把戏剧的骚乱给生态系统 biogeochemical 周期。SHENG Wenping REN Shujie YU Guirui FANG Huajun JIANG Chunming ZHANG Mi 2011Journal of Geographical Sciences2011,21,4:19
2Aggf1 attenuates hepatic inflammation and activation of hepatic stellate cells by repressing Ccl2 transcription显示文摘Liver injury represents a continuum of pathophysiological processes involving a complex interplay between hepatocytes, macrophages, and hepatic stellate cells. The mechanism whereby these intercellular interactions contribute to liver injury and fibrosis is not completely understood. We report here that angiogenic factor with G patch and FHA domains 1(Aggfl) was downregulated in the livers of cirrhotic patients compared to healthy controls and in primary hepatocytes in response to carbon tetrachloride(CC14) stimulation. Overexpression of Aggfl attenuated macrophage chemotaxis. Aggfl interacted with NF-κB to block its binding to the Ccl2 gene promoter and repressed Ccl2 transcription in hepatocytes. Macrophages cultured in the conditioned media collected from Aggfloverexpressing hepatocytes antagonized HSC activation. Taken together, our data illustrate a novel role for Aggfl in regulating hepatic inflammation and provide insights on the development of interventional strategies against cirrhosis.Wenping Xu Sheng Zeng Min Li Zhiwen Fan Bisheng Zhou 2017The Journal of Biomedical Research2017,31,5:2
3On cross-correlation indicators of an S-box显示文摘替换盒子(S 盒子) 经常在许多对称的加密算法被用作最重要的非线性的部件。S 盒子的密码的性质直接影响整个零系统的安全。最近,概括了全球雪崩特征(GGAC ) 被介绍测量在二任意的布尔功能之间的关联。在这份报纸,更好评估 S 盒子的安全,我们在场为它的二跨关联的指示物。另外,由学习相关性质在二平衡布尔功能之间跨关联,我们为 S 盒子为二平衡功能并且也在与 GGAC 有关的 sum-of-squares 指示物上建议更低的界限。Sheng GAO Wenping MA Zepeng ZHUO Fenghe WANG 2011Frontiers of Computer Science2011,5,4:2
4Theoretical analysis and simulation of InP-based uni-traveling-carrier photodetector显示文摘In this paper the photocurrent response of InP-based unitraveling-carrier photodetectors(UTC-PDs) is analyzed using the drift-diffusion approach.Based on the theoretical analysis,an InP/InGaAs UTC-PD is modeled utilizing a numerical device simulator(ATLAS),and the physics of the device's operation and its performance as a function of biasing and power level are simulated.The simulation results indicate that the linear dynamic range is up to 60 mW,the f-3 dB is about 40 GHz and the full-width at half-maximum(FWHM) of the current pulse is 28 ps with 10 mW optical power injection for an optimized structure UTC-PD.XIE Sheng LIU LiSa KANG WenPing SONG RuiLiang MAO LuHon ZHANG ShiLin 2009Chinese Science Bulletin2009,54,20:1

6High-Order Bit Independence Criterion Test for the S-boxes显示文摘A new security test for the substitution boxes (S-boxes),high-order bit independence criterion (HOBIC) test,is presented.Different from the previous security tests for S-boxes,the HOBIC test can be used to measure the strength of an S-box against attacks that keep some of its input bits constant.Test results over the S-boxes of Data Encryption Standard (DES) and Advanced Encryption Standard (AES) are given and some possible applications of the HOBIC test are analyzed.Meanwhile,the source code for a basic version of the HOBIC test is also provided,the implement process of which shows that it is very fast and efficient for practical applications.GAO Sheng MA Wenping ZHU Jiwei 2011Wuhan University Journal of Natural Sciences2011,16,5:0
7Evolutionary Multitask Optimization in Real-World Applications: A Survey显示文摘Because of its strong ability to solve problems,evolutionary multitask optimization(EMTO)algorithms have been widely studied recently.Evolutionary algorithms have the advantage of fast searching for the optimal solution,but it is easy to fall into local optimum and difficult to generalize.Combining evolutionary multitask algorithms with evolutionary optimization algorithms can be an effective method for solving these problems.Through the implicit parallelism of tasks themselves and the knowledge transfer between tasks,more promising individual algorithms can be generated in the evolution process,which can jump out of the local optimum.How to better combine the two has also been studied more and more.This paper explores the existing evolutionary multitasking theory and improvement scheme in detail.Then,it summarizes the application of EMTO in different scenarios.Finally,according to the existing research,the future research trends and potential exploration directions are revealed.Yue Wu Hangqi Ding Benhua Xiang Jinlong Sheng Wenping Ma Kai Qin Qiguang Miao Maoguo Gong 2023Journal of Artificial Intelligence and Technology2023,3,1:0
