Based on the subdivision into three members of the Lower Cretaceous Jiufotang Formation in western Liaoning, this paper deals mainly with the division and correlation of precious fossil birdand reptile-bearing beds of the formation in the Dachengzi, Chaoyang, *** and Fuxin-Yixian basins. Among them, the precious fossil-bearing beds in the Dachengzi Basin may be recognized as the Xidagou Bed of the second member and the Yangcaogoudonggou Bed of the third member; those in the Chaoyang Basin may be confirmed as the Shangheshou Bed of the second member and the Dongpochi Bed of the third member; those in the Dapingfang-Meileyingzi Basin are as the Lamagou Bed of the second member, the Huanghuagou Bed of the lower third member and the Yuanjiawa Bed of the upper third member; and those in the Fuxin-Yixian Basin are listed as the Tuanshanzi Bed of the second member and the Pijiagou Bed of the third member. Since these basins are distinctly separated and the bird and reptile fossils are mostly new genera and species, we have to use the associated fossil ostracod assemblages as index to correlate the Xidagou Bed with the Shangheshou Bed and the Lamagou Bed, and to correlate the Yuanjiawa Bed with the Yangcaogoudonggou Bed and the Pijiagou Bed. Primarily, we established the sequence of the precious fossil-bearing beds of the Jiufotang Formation in western Liaoning. They are represented by, in ascending order, the Xidagou Bed of the second member, the Huanghuagou Bed of the lower third member, and the Yuanjiawa Bed of the upper third member. Obviously, this work has significance for the study on the time-space distribution and radiation of birds and dinosaurs during the period of the middle Early Cretaceous.

在聚变反应堆运行过程中,中子活化会导致大量放射性核素的产生,因此活化计算在反应堆的屏蔽设计和辐射安全分析中具有重要作用。本文基于蒙特卡罗粒子输运程序cosRMC的内置燃耗求解器Depth,开发了固定源模式下的内耦合输运-活化耦合计算功能。将该程序应用于中国聚变工程试验堆(Chinese Fusion EngineeringTestingReactor,CFETR)的第一壁(First-wall,FW)材料钢和面向等离子体部件(Plasma-facing Component,PFC)材料钨,分别使用连续能量截面和多群截面进行活化计算,并与活化程序ALARA进行对比验证,发现cosRMC的计算结果与ALARA计算的结果符合良好,初步验证了开发的cosRMC程序输运-活化内耦合计算功能的正确性。与传统蒙特卡罗-活化计算程序的外耦合方式相比,内耦合方式蒙特卡罗不需要把中子能谱传给外部活化程序,而是在蒙特卡罗中子输运过程中嵌入计算活化相关的核素单群反应截面,动态更新中子能谱和材料信息,同时可以使用连续能量截面进行反应率计算,得到与实际问题的几何、能谱相关的反应截面,从而精确地考虑了共振区核截面的影响。

Compute-in-memory(CIM) based on various devices such as static random access memory(SRAM) and resistive random access memory(RRAM) and other emerging devices such as indium-gallium-zinc-oxide(IGZO) transistor, magnetoresistive RAM(MRAM), and ferroelectric RAM(FeRAM) has been explored for better performance and energy efficiency on neural networks applications. However, CIM based on a single-type device suffers a variety of non-ideal metrics to reach the simultaneous optimal accuracy, density, and energy efficiency. This work presents equivalent-ideal CIM(Eq-CIM), a monolithic 3D(M3D) IGZO-RRAM-SRAM integrated architecture for robust and efficient compute-in-memory enabling equivalent-ideal device metrics. To overcome the non-ideality(variation, endurance, temperature, etc.) of the single-type devices, system-technology co-optimization(STCO) is performed. This work highlights the non-ideality-aware functionality breakdown for robust high accuracy and simultaneous high density/efficiency, by utilizing 2T0C IGZO for temporal activation storage, RRAM for high-density weight storage, and SRAM for accurate CIM. Device-to-algorithm variation transfer is applied to analyze the system-level accuracy. We benchmark Eq-CIM architecture on CIFAR-10/ImageNet, with 5.06× storage density and 5.05×/2.45× area/energy efficiency compared with single-type-device-based CIM, and high robustness(<0.27% accuracy loss) from-40℃ to 120℃.
