To improve the amylose content(AC)and resistant starch content(RSC)of maize kernel starch,we employed the CRISPR/Cas9 system to create mutants of starch branching enzyme I(SBEI)and starch branching enzyme IIb(SBEIIb).A frameshift mutation in SBEI(E1,a nucleotide insertion in exon 6)led to plants with higher RSC(1.07%),lower hundred-kernel weight(HKW,24.71±0.14 g),and lower plant height(PH,218.50±9.42 cm)compared to the wild type(WT).Like the WT,E1 kernel starch had irregular,polygonal shapes with sharp edges.A frameshift mutation in SBEIIb(E2,a four-nucleotide deletion in exon 8)led to higher AC(53.48%)and higher RSC(26.93%)than that for the WT.E2 kernel starch was significantly different from the WT regarding granule morphology,chain length distribution pattern,X-ray diffraction pattern,and thermal characteristics;the starch granules were more irregular in shape and comprised typical B-type *** SBEI and SBEIIb(E12)had a synergistic effect on RSC,HKW,PH,starch properties,and starch biosynthesis-associated gene ***,SS1,SSIIa,SSIIIa,and SSIIIb were upregulated in E12 endosperm compared to WT *** study lays the foundation for rapidly improving the starch properties of elite maize lines.

Real-time predicting of stochastic waves is crucial in marine *** this paper,a deep learning wave prediction(Deep-WP)model based on the‘probabilistic’strategy is designed for the short-term prediction of stochastic *** Deep-WP model employs the long short-term memory(LSTM)unit to collect pertinent information from the wave elevation time *** irregular long-crested waves generated in the deepwater offshore basin at Shanghai Jiao Tong University are used to validate and optimize the Deep-WP *** the prediction duration is 1.92s,2.56s,and,3.84s,respectively,the predicted results are almost identical with the ground *** the prediction duration is increased to 7.68s or 15.36s,the Deep-WP model’s error increases,but it still maintains a high level of accuracy during the first few *** introduction of covariates will improve the Deep-WP model’s performance,with the absolute position and timestamp being particularly advantageous for wave ***,the Deep-WP model is applicable to predict waves with different energy *** proposed Deep-WP model shows a feasible ability to predict nonlinear stochastic waves in real-time.

针对网联车辆行驶过程中容易出现旁车道的人类驾驶员并线进入车队的问题,本文中提出了一种考虑旁车并线行为的跟车策略,并设计了分布式应用的分层控制系统。首先分析了所提出的跟车策略的合理性,并构建了考虑延时与误差反馈的联网巡航控制(CCC)系统;接着在频域范围内分析了不同控制增益参数对系统稳定性的影响,仿真结果验证了多车队列行驶稳定性;最后搭建测试平台进行实车试验。结果表明:旁车并线时,CCC控制系统可快速实现车辆的制动并保证队列的稳定性,所提出的跟车策略可提升车辆的乘车舒适性与交通系统的安全性。
