The principle of surgical treatment for gastric cancer is the radical resectioning although the suitable resecting range for different cases of gastric cancer is still being argued upon[1-9]. However, the diagnostic accuracy of early gastric cancer (EGC) without lymphatic metastasis has obviously improved with an improvement in the diagnostic technique and due to the accumulation of knowledge on the biological profiles of EG C[10-17]. The D2 lymph node excision was used as a regular operation to treat the EGC previously. But the concept for the EGC without lymphatic metastasis has gradually changed and the less invasive resections has been applied in some cases[18-20]. This study aimed at investigating the risk factors of lymphatic metastasis in EGC in order to find out the proofs for the suitable indications for less invasive operations such as endoscopic mucosal resectioning (EMR), laparoscopic and laparotomic resectioning.

Area has become one of the main bottlenecks restricting the development of integrated circuits. The area optimization approaches of existing XNOR/OR-based mixed polarity Reed-Muller(MPRM) circuits have poor optimization effect and efficiency. Given that the area optimization of MPRM logic circuits is a combinatorial optimization problem, we propose a whole annealing adaptive bacterial foraging algorithm(WAA-BFA), which includes individual evolution based on Markov chain and Metropolis acceptance criteria, and individual mutation based on adaptive probability. To address the issue of low conversion efficiency in existing polarity conversion approaches, we introduce a fast polarity conversion algorithm(FPCA). Moreover, we present an MPRM circuits area optimization approach that uses the FPCA and WAA-BFA to search for the best polarity corresponding to the minimum circuits area. Experimental results demonstrate that the proposed MPRM circuits area optimization approach is effective and can be used as a promising EDA tool.

Achieving a highly robust zinc(Zn)metal anode is extremely important for improving the performance of aqueous Zn-ion batteries(AZIBs)for advancing“carbon neutrality”society,which is hampered by the uncontrollable growth of Zn dendrite and severe side reactions including hydrogen evolution reaction,corrosion,and passivation,***,an interlayer containing fluorinated zincophilic covalent organic framework with sulfonic acid groups(COF-S-F)is developed on Zn metal(Zn@COF-S-F)as the artificial solid electrolyte interface(SEI).Sulfonic acid group(-SO_(3)H)in COF-S-F can effectively ameliorate the desolvation process of hydrated Zn ions,and the three-dimensional channel with fluoride group(-F)can provide interconnected channels for the favorable transport of Zn ions with ion-confinement effects,endowing Zn@COF-S-F with dendrite-free morphology and suppressed side ***,Zn@COF-S-F symmetric cell can stably cycle for 1,000 h with low average hysteresis voltage(50.5 m V)at the current density of 1.5 m A cm^(-2).Zn@COF-S-F|Mn O_(2)cell delivers the discharge specific capacity of 206.8 m Ah g^(-1)at the current density of 1.2 A g^(-1)after 800 cycles with high-capacity retention(87.9%).Enlightening,building artificial SEI on metallic Zn surface with targeted design has been proved as the effective strategy to foster the practical application of high-performance AZIBs.

为探讨不同地膜覆盖方式对大蒜种植系统中土壤质量与大蒜产量的影响,确定大蒜种植中的最佳地膜管理模式.基于2021年设置在江苏省农业科学院大蒜种植系统的不同地膜覆盖试验,研究大蒜种植体系中无地膜处理(CK)、黑色聚乙烯地膜处理(HPE)、黑色聚对苯二甲酸-己二酸-丁二醇酯(PBAT)/秸秆复合地膜处理(HSJ)和白色PBAT地膜处理(bj)对土壤质量及大蒜产量变化的影响.结果表明:①不同地膜覆盖处理下,土壤理化性质和细菌、真菌数量发生显著变化,并间接改善土壤质量.相较不覆膜处理,bj处理土壤质量指数提升70%,综合效果最好,其次是HPE和HSJ处理,分别提升52%和36%.随机森林模型分析发现,土壤有机质和全氮是影响土壤质量的主要因素.②不同地膜覆盖显著提高蒜头直径和大蒜单头质量,且处理间无显著差异,其中HSJ处理大蒜产量提高效果最好,分别比CK、HPE和bj处理提高了46%、19%和6%.③相关性分析表明,地膜覆盖下土壤质量指数与大蒜鳞茎淀粉含量、蒜头直径、大蒜单头质量显著相关.研究结果从大蒜种植过程中覆盖地膜选择的角度,为高质量与高产量农田结合发展提供了科学依据.

动态键值记忆网络知识追踪作为知识追踪领域的代表性模型,通过引用注意力机制提高了模型的可解释性,但未考虑异常学习行为对学生状态更新的影响,也存在添加学习特征损害模型可解释性的问题.针对以上不足,本文提出模型DKVMN-PLC(Dynamic Key-value Memory Network with Personalized Learning Characteristics).首先,基于协同过滤思想,提出一种使用整体、阶段性学习能力判断异常学习行为的方法,量化了异常学习行为对更新学习状态的影响,提高学生状态建模的准确性.其次,提出一种存储器特征与个性化特征的融合方法,使用特征工程、聚类技术将特征分别用于同步存储器和预测学生表现,提高模型使用键值对获取学生信息的准确性.将DKVMN-PLC与5个知识追踪模型在3个数据集上进行了对比实验,DKVMN-PLC模型表现均为最优.

采用数值仿真方法对椭圆锥孔在高压涡轮导叶前缘的气膜冷却效率进行了探究,分析对比了椭圆柱孔的两个结构参数流向扩张角和径向扩张角对前缘气膜冷却效率的影响,且分别在流向扩张角为0°~18°和径向扩张角为0°~16°范围内对椭圆锥孔进行了优化。结果表明:流向扩张角为1.4°且径向扩张角为11.1°时的椭圆锥孔表现出最高的气膜冷却效率,其相较于圆柱孔的冷却效率提升了147.5%,且椭圆锥孔的结构参数随气膜冷却效率的变化规律可拟合成四次方函数关系,当径向扩张角很小时,气膜冷却效率随流向扩张角增大,反之,气膜冷却效率基本随流向扩张角增大而减小;当流向扩张角较小时,气膜冷却效率大致随径向扩张角的增大而先增后减,当流向扩张角较大时,气膜冷却效率基本保持不变或呈现一个较小的增幅。
