GaN-based high-electric-mobility transistors(HEMTs) have been investigated thoroughly because of their promising applications in high-frequency,-voltage, and-power applications. However, the theoretical material limit prevents conventional single-heterostructure GaN HEMTs from achieving high performance despite numerous efforts [1–3].

卷积长短期记忆单元ConvLSTM和卷积门控循环单元ConvGRU是两种广泛应用的深度学习单元,通过将循环机制与卷积运算相结合,常常用于时空序列的预测.为了明确上述两种模型的收敛速度和分类能力,需要使用相同的模型架构对相同的分类问题进行预测.本研究将北京短时强降水区级预警问题看作深度学习中的二分类问题,使用京津冀雷达网的组合反射率数据和北京区域内的自动气象站降雨数据进行深度学习模型的训练和评估.结果表明,ConvGRU的收敛速度比ConvLSTM快约25%.ConvLSTM和ConvGRU的预警性能随地区,时间,降雨强度的变化趋势相似,但大部分ConvLSTM的得分较高,少数情况下ConvGRU的得分较高.

马克思在《黑格尔法哲学批判》中揭示并拆解了黑格尔国家哲学中的“表现”机制,也即黑格尔何以可能将市民社会处理为由于无法通过自身获得意义因而必须被政治国家统摄在一个由“现实的观念”即绝对精神所推动并作为其“表现”的关系整体中。马克思的讨论包括三个层面:市民社会和政治国家为何无法仅凭自身而获得自己的意义;市民社会和政治国家是如何联系在一起的;市民社会本身究竟有无可能获得自身的意义。马克思在这一工作中开启了对于“事物本身的逻辑”的追问,其基本形式是对“事物与自身的关系”的分析也即意义分析,其基本成果是在传统的法权主体与道德主体框架之外发现了进行自我规定并获得自身特有的历史性存在方式的意义主体。这是马克思以意识形态批判的方式探讨历史性之建构问题的初次尝试,具有深远理论意义。

开发了一种耦合并行-自适应网格划分算法的相场-格子玻尔兹曼方法来模拟hcp金属的等轴和柱状枝晶生长,重点讨论了重力驱动的自然对流以及自然对流与强制对流耦合对枝晶生长的影响。模拟结果表明,二维情况下的hcp金属枝晶在重力驱动的自然对流下呈现非对称生长,同时揭示了溶质偏析和溶质羽流的演化过程。研究得出,溶质羽流的形成是由枝晶的溶质阻塞和熔体流动时溶质传输之间的竞争决定的。引入适当的强制对流可以消除溶质羽流的形成并抑制枝晶尖端溶质浓度的局部波动。研究还发现,重力驱动的自然对流丰富了hcp金属3D枝晶形貌的多样性。

Hard carbon(HC)is broadly recognized as an exceptionally prospective candidate for the anodes of sodium-ion batteries(SIBs),but their practical implementation faces substantial limitations linked to precursor factors,such as reduced carbon yield and increased ***,a cost-effective approach is proposed to prepare a coal-derived HC anode with simple pre-oxidation followed by a post-carbonization process which effectively expands the d_(002)layer spacing,generates closed pores and increases defect *** these modifications,the resulting HC anode attains a delicate equilibrium between plateau capacity and sloping capacity,showcasing a remarkable reversible capacity of 306.3 mAh·g^(-1)at 0.03 A·g^(-1).Furthermore,the produ ced HC exhibits fast reaction kinetics and exceptional rate performance,achieving a capacity of 289 mAh·g^(-1)at 0.1 A·g^(-1),equivalent to~94.5%of that at 0.03 A·g^(-1).When implemented in a full cell configuration,the impressive electrochemical performance is evident,with a notable energy density of 410.6 Wh·kg^(-1)(based on cathode mass).In short,we provide a straightforward yet efficient method for regulating coal-derived HC,which is crucial for the widespread use of SIBs anodes.
