Ethylene is a gaseous hormone which plays important roles in both plant growth and development and stress responses. Based on studies in the dicot model plant species Arabidopsis, a linear ethylene signaling pathway has been established,according to which ethylene is perceived by ethylene receptors and transduced through CONSTiTUTiVE TRiPLE RESPONSE 1(CTR1) and ETHYLENE-iNSENSiTiVE 2(EiN2) to activate transcriptional reprogramming. in addition to this canonical signaling pathway, an alternative ethylene receptor-mediated phosphor-relay pathway has also been proposed to participate in ethylene signaling. in contrast to Arabidopsis, rice, a monocot, grows in semiaquatic environments and has a distinct plant structure. Several novel regulators and/or mechanisms of the rice ethylene signaling pathway have recently been identified,indicating that the ethylene signaling pathway in rice has its own unique features. in this review,we summarize the latest progress and compare the conserved and divergent aspects of the ethylene signaling pathway between Arabidopsis and rice. The crosstalk between ethylene and other plant hormones is also reviewed. Finally, we discuss how ethylene regulates plant growth, stress responses and agronomic traits. These analyses should help expand our knowledge of the ethylene signaling mechanism and could further be applied for agricultural purposes.

高精度时频比对是现代科学技术的核心需求之一.然而,现有的技术受限于比对系统测量水平和链路系统误差处理算法,严重限制了时间比对性能的提升.针对这些问题,本研究搭建了基于中国空间站的高精度星地微波时频比对系统,并提出了一种基于双向测量的空间站-地面时频比对技术(三频模式),包括了对各项链路系统误差精细化建模新方法.通过对不同星地时频比对场景的仿真模拟发现,在配置高精度原子钟(10^(−15)~10^(−17))进行星地时频比对的场景下,经过本文算法优化后的比对长期性能仍可达与原本星地时钟相近的性能.利用中国空间站所搭载的氢钟与地面氢钟进行初步比对试验结果表明,在300 s可视弧段内的空间站-地面时间比对精度可达到10.77 ps,相应的ADEV(Allan DEViation)达到9.9921×10^(−14)@100 s,与仿真模拟结果大致吻合.本研究可为精密时频同步技术提供了新的理论依据和技术参考.

The XRD, TEM, PAT, Curie temperature and internal friction methods were used to study systematically the embrittlement mechanism of rapidly quenched ( RQ ) nanocrystalline soft magnetic alloy *** test results confirmed that the RQ embrittlement mechanism of amorphous alloy FeCuNbSiB was not related to crystallization but that was related to structural relaxation. Furthermore, the structural relaxation temperature of amorphous alloy FeCuNbSiB was much lower than that of used commonly amorphous alloy Fe78B13Si9. it meant that the RQ embrittlement is easier to happen for nanocrystalline alloy FeCuNbSiB than amorphous alloy Fe-B-Si.

To fully exploit the performance benefits of relay station （RS）, in the two-hop cellular networks covering hotspots, when the number of RSs is predetermined, both RS deployment and frequency reuse scheme are jointly optimized for the purpose of maximizing the system capacity based on the constraints of system demand of capacity and the maximum number of outage demand nodes （MNDN）. Further, considering the overhead of increasing RSs, it is desired to use minimum number of RSs. The joint RS deployment and frequency reuse scheme （JRDFR） problem is formulated into a mixed integer nonlinear programming, which is non-deterministic polynomial-time hard in general. A heuristic approach based on genetic algorithm is proposed to tackle the JRDFR problem. The computational experiment of the heuristic approach is achieved and optimized RS deployment and frequency reuse scheme is obtained. Finally, we discuss the impacts of MNDN and the number of RSs on the system performance.
