Leaf senescence can impact crop production by either changing photosynthesis duration, or by modifying the nutrient remobiliza- tion efficiency and harvest index. The doubling of the grain yield in major cereals in the last 50 years was primarily achieved through the extension of photosynthesis duration and the increase in crop biomass partitioning, two things that are intrinsically coupled with leaf senescence. In this review, we consider the functionality of a leaf as a function of leaf age, and divide a leaf＇s life into three phases： the functionality increasing phase at the early growth stage, the full functionality phase, and the senescence and functionality decreasing phase. A genetic framework is proposed to describe gene actions at various checkpoints to regulate leaf development and senescence. Four categories of genes contribute to crop production： those which regulate （Ⅰ） the speed and transition of early leaf growth, （Ⅱ） photosynthesis rate, （Ⅲ） the onset and （Ⅳ） the progression of leaf senescence. Current advances in isolating and characterizing senescence regulatory genes are discussed in the leaf aging and crop production context. We argue that the breeding of crops with leaf senescence ideotypes should be an essential part of further crop genetic improvement.

Mechanical properties of the glassy specimens fabricated at different cooling rates with a composition of Ti40Zr25Cu12Ni3Be20 were systematically investigated. It was confirmed that faster cooling rates caused not only a larger amount of frozen-in free volume but also a higher glass transition temperature in the bulk glassy alloy. Increase in the free volume was found to favor plastic deformation and then to give rise to larger compressive plasticity, whilst the rise in the glass transition temperature seemed to be closely related to the higher yield strength. Moreover, the increase of yield strength and plasticity induced by fast cooling rates may also be associated with the residual stress generated during the fabrication process. Our results suggest that the deformation behavior of bulk metallic glasses is sensitive to various factors and influences from the other factors should be excluded as far as cooling-rate effects on bulk metallic glasses are considered.

针对现有算法对尖锐特征曲面点云法矢估计不准确,点云处理时容易丢失曲面细节特征等问题,提出一种尖锐特征曲面散乱点云法向估计法。该方法用主成分分析法粗估计点云法向;然后,根据各邻域点的空间欧氏距离和法向距离对各邻域法向加权,用加权邻域法向之和来更新当前点的法向;最后,测试估计法向与标准法向的误差,评价估计法矢的准确性,并且将估计的法向应用到点云数据处理中来比较特征保留效果。实验结果表明:本文方法能够准确地估计尖锐特征曲面的法向,最小误差接近0。另外,该方法对噪声有较好的鲁棒性,点云处理时能保留曲面的尖锐特征。相比于其他特征曲面法向估计法,所提出的方法估计的法向误差更小、速度更快、耗时更少。
