采用营养液水培的方法,以‘改良毛粉802F1’番茄为供试材料,通过检测番茄植株内激素、根系分泌物、氨基酸、电解质渗漏率和生物量的变化,研究外源2,4-表油菜素内酯(2,4-EBR,EBR)对Cu胁迫下番茄的缓解效应及机制。结果表明,与Cu胁迫处理相比,喷施0.1 mg·L-1的EBR能显著提高叶片内源ZR和GA含量,显著降低根系中ZR、ABA和IAA的含量,同时提高番茄植株内各种有机酸的含量,其中柠檬酸含量升高482.2%,乳酸含量为0.187 mg·g-1。植株中氨基酸总量增加了11.1%,生物量增加20.9%。表明外源EBR可以降低Cu的生物毒性,减缓过多Cu对番茄幼苗的抑制作用。

一氧化氮(NO)作为生物活性分子,广泛参与各种生物、非生物胁迫。采用营养液培养,研究铜胁迫下外源NO对番茄体内植物螯合肽及精氨酸代谢的影响。结果表明,与CK相比,铜胁迫可以显著激活番茄体内γ-ECS、GS活性,根系GSH、PCs含量急剧升高,且随着处理时间的延长,γ-ECS、GS酶活性、GSH、PCs含量呈持续上升趋势;同时促进植物体内精氨酸代谢增加多胺合成。添加外源SNP,进一步提高铜胁迫下番茄根系γ-ECS、GS活性,促进GSH、PCs的合成,促进番茄多胺的合成。铜胁迫下,外源NO可能启动了某些信号机制,并通过激活或增强某些酶促和非酶促系统,降低过多Cu2+的生物毒性和氧化伤害。

An online electricity cost budgeting algorithm for maximizing green energy usage across data centers

引用

Frontiers of Computer Science 2017年第4期11卷 661-674页

作者： hui dou Yong QI School of Electronic and Information Engineering Xi'an Jiaotong University Xi'an 710049 China

With the sky-rocketing development of Internet services, the power usage in data centers has been signifi- cantly increasing. This ever increasing energy consumption leads to negative environmental impact such as global warming. To reduce their carbon footprints, large Internet service operators begin to utilize green energy. Since green energy is currently more expensive than the traditional brown one, it is important for the operators to maximize the green en- ergy usage subject to their desired long-term （e.g., a month） cost budget constraint. In this paper, we propose an online algorithm GreenBudget based on the Lyapunov optimization framework. We prove that our algorithm is able to achieve a delicate tradeoff between the green energy usage and the en- forcement of the cost budget constraint, and a control parameter V is the knob to arbitrarily tune such a tradeoff. We evaluate GreenBudget utilizing real-life traces of user requests, cooling efficiency, electricity price and green energy avail- ability. Experimental results demonstrate that under the same cost budget constraint, GreenBudget can increase the green energy usage by 11.55% compared with the state-of-the-art work, without incurring any performance violation of user requests.

Multiple Forced Rotational Solutions for the Planar N-pendulum Equation

Acta Mathematica Sinica,English Series 2018年第2期34卷 171-193页

作者： hui qiao School of Mathematics and Statistics Wuhan University

Abstract This paper presents a theorem of existence of （N - N0＋1）2No noncontractible periodic orbits of any given rotational vector with zero components for the planar forced N-pendulum equation, where No denotes the number of zero components of given rotational vector. We make special arrangements for masses and length instead of the nondegenerate assumption. Moreover, for rotational vectors with identical components, similar results are also obtained.
