Dear editor,Gate-all-around(GAA) nanosheet transistor(NST) is one of the most promising candidates to replace Fin FET as the next generation because of its best electrostatic integrity and gate control over the channel [1]. However, statistical variability induced by traditional statistical variation sources including random discrete dopants(RDD), line edge roughness(LER), metal gate granularity(MGG), and strong quantum confinement effect has severely limited the performance improvement of NST, which requires a comprehensive study.

文章对“一带一路”倡议提出十年来国际社会较为典型的三种质疑进行了分析、回应与澄清,对这一倡议在未来的顺利推进具有积极正向的国际舆论引导作用。文章认为:“一带一路”倡议与“马歇尔计划”在提出背景、理念和具体经济交往内容、形式以及最终目的上都有着根本性的不同,它不是中国版的“马歇尔计划”;“一带一路”倡议在发展实践中,不但没有制造和加重沿线国家的债务危机,反而对许多沿线国家降低债务、化解债务风险和危机起到了积极的促进作用;“一带一路”倡议的提出不是为了挑战现有国际秩序,而是要通过“共商、共建、共享”促进各国经济的共同发展和繁荣,最终实现构建人类命运共同体的宏伟目标。

针对典型的飞行器制导任务,利用深度学习算法可以有效地拟合导弹飞行状态与制导指令之间的函数关系。然而当制导任务发生变化时,其二者之间的映射关系也会随之改变,从而导致在当前环境下预训练好的模型无法直接作用于新环境,重新训练制导模型需要大量的弹道数据和巨额的时间成本。为解决上述问题,基于迁移学习的思想引入域对抗神经网络,提出基于迁移学习的多任务制导算法。以1个含有大量标签数据的源域任务辅助2个含有极少量标签数据的目标域任务进行迁移学习,从而克服预训练与在线控制之间的环境差异。使用特征提取器和域判别器提取出对任务环境不敏感的关键特征,使神经网络学习到各个任务所共享的底层信息;为提高预测精度,分别设计针对不同任务的偏置加速度预测器。数值仿真结果表明:基于迁移学习的多任务制导算法实现了导弹在不同任务中的加速度指令预测。
