Recently,discriminative machine learning models have been widely used to predict various attributes from Electron Backscatter Diffraction(EBSD)***,there has never been any generative model developed for EBSD pattern *** one hand,the training of generative models is much harder than that of discriminative ones;On the other hand,numerous variables affecting EBSD pattern formation make the input space high-dimensional and its relationship with the distribution of backscattered electrons *** this study,we propose a framework(EBSD-CVAE/GAN)with great flexibility and scalability to realize parametric simulation of EBSD *** with the frequently used forward model,EBSD-CVAE/GAN can take variables more than just orientation and generate corresponding EBSD patterns in a single *** accuracy and quality of generated patterns are systematically *** model does not only summarize a distribution of backscattered electrons at a higher level,but also mitigates data scarcity in this field.

以25份克拉克和6份哈罗索近等基因系为试材,研究了播种时期,成熟期,结荚习性,抑制褐斑形成,抗病毒病及某些控制种皮颜色基因对大豆籽粒斑驳形成的影响。采用完全随机区组裂区设计。研究结果表明,播种时期对大豆的成熟期,大豆花叶病毒病及籽粒斑驳的严重度具有很大的影响。随着播期的推迟,从苗期到成熟所需要的日数明显减少,病毒病、斑驳粒率(PMS)和斑驳指数(MI)明显减轻。基因替换效应分析表明,tE1,E2,E3,Im和Rsv1对减轻籽粒斑驳症状具有显著的效应。当上述基因被其隐性等位基因替换时,斑驳粒率和斑驳指数分别减少32.1％和0.205,8.8％和0.043,6.3％和0.031,27.1％和0.212,25.3％和0.156。TE1,i—k和iR对加重籽粒斑驳的形成具有显著的效应,当这几个基因或基因组合被tel,i—i和Ir所替换时斑驳粒率和斑驳指数分别降低13.8％和0.126,28.7％和0.449,6.43％和0.115。虽然R和Dtl对大豆花叶病毒病症状表现有较大的影响,但是对籽粒斑驳的形成影响不大。

Annals of Differential Equations 1996年第2期12卷 137-146页

作者： John R. graef.& Paul W. Spikes (Mississippi State University, Mississippi State, MS 39762) Mississippi State University Mississippi State MS 39762 sl.ap-hop-paris.fr

The authors consider the forced nonlinear neutral delay equation [y(t) + P(t)y(g(t)]' - Q(t)f(y(h(t)) = R(t) (E)where P,Q,R,g,h: [t0,∞)→R are continuous, g(t)≤t,h(t)≤t,g(t)→∞ and h(t)→ ∞ as t →∞, Q(t)≥0, f:R →R is continuous, and uf(u) > 0 for u ≠0. Sufficient conditions are placed on P,Q,f, and R so that certain classes of solutions of (E) tend to zero as t →∞. Some suggestions for further research are also indicated.1991 Mathematics Subject Classification. Primary 34K40, 34K15; Secondary 34C11,34C15.

虽然政府频频出台新能源利好政策,希望刺激消费者购买欲望,但研究显示,仅靠政策单方面刺激很难完成到2020年累计销售500万辆新能源车的目标,需要地方政府、汽车OEM和电网公司共同致力于推动新能源汽车的成功发展,解决充电等难题,从根本上消除消费者的顾虑。"中国消费者对新能源汽车(NEV)的兴趣及购买意愿仍不足以实现中国政府新能源汽车销量的目标。"中国是全球最大的汽车市场,而汽车业如火如荼的发展也同时造成了大城市的严重交通拥堵和空气污染。
