Abstract： The self is a unique structure with unique motivations and emotional significance and the processing of self-related information has its own characteristics. These characteristics are reflected not only in the advantage of remembering self-related information, but also in the influence of the emotional perception of other people's faces. However, there has been little research on how the evaluation of one's mother affects the perceptual processing of others' emotions and whether there is consistency between the perceptual processing of others' emotions and the self's maternal reference and self-reference. To address this question, this study combined the evaluation contexts of the self, the mother, and other people's faces in a facial emotion assessment task to investigate whether the neural representations of self-reference and mother-reference are consistent in Chinese people's emotional processing. The participants were asked to rate the facial emotions of strangers in different valence evaluation contexts (negative, neutral, or positive) and based on different references (self-reference, mother-reference, other-reference, and no-reference). Except for neutral emotions, three reference contexts of positive or negative emotions were expressed through the personality trait words, while no-reference contexts were mainly noun contexts. For example, Lanzhou is the provincial capital of Gansu Province. At the beginning of the experiment, participants were presented with evaluative or declarative contextual material. We emphasized that the contextual material was the subsequent face statement. The neutral emotional face stimulus was presented after the contextual material. After the face stimulus disappeared, participants were asked to judge the valence and arousal of facial emotion. The changes in neural activity during the processing of facial emotion were recorded. The event-related potential (ERP) components of interest in this study are P1 and N170, which are related to early automatic processing of facial emotion, EPN components related to selective attention processing of facial emotion information, and LPP components reflecting late processing of facial emotion. The behavioral results showed that the faces in the self-reference and mother-reference contexts were more aroused than those in the other-reference contexts. Moreover, the faces in the negative context were perceived as more negative and the faces in the positive context were perceived as more positive. The ERP results showed that different valence and reference contexts had no significant influence on the early components (P1 and N170) of facial emotion perception, but that they influenced the relatively late components EPN and LPP. Compared with the contexts of un-reference and other-reference, the contexts of self-reference and mother-reference caused larger amplitudes in EPN and LPP. Furthermore, the emotional context (negative or positive) caused larger amplitudes than the neutral context. It is worth noting that there is no significant difference in the results of both behavioral and ERP levels between self-reference and mother-reference conditions. The results of this study showed that the mothers of Chinese individuals affect their perception and processing of other people's faces. Self-reference and mother-reference were consistent in face emotional processing. This result is highly consistent with previous research, suggesting that mothers shares neural representations with the self. This study is the first to provide ERP evidence of the inclusion of mothers in Chinese self-concept from the perspective of emotional processing.

Abstract： Objective: To establish a multi-dimensional and standardized lexical database of COVID-19-related terms and words. The database may have facilitated COVID-19-related research in domains such as Psychology, Psychiatry, Neuroscience, etc. Methods: This database referred to the established methods of the emotional lexical database at home and abroad, and used the dot-detection task and words in the database as experimental materials to test the attention bias of the subjects suspected of having COVID-19 phobia, so as to test the validity of the database. Results: 196 COVID-19-related words and 99 neutral words were included in the word database. Then, we classified and evaluated the words through six dimensions, and established a standardized database of Chinese COVID-19-related terms. The words have good reliability and internal consistency. In addition, the validity was tested through the dot-detection task. Subjects with COVID-19 fear and those without COVID-19 fear showed a significant attentional bias toward COVID-19-related words Limitations: The initial sample size is small and the database application needs further development. Conclusions: The database of Chinese COVID-19 terms has good reliability, internal consistency, and reliability, and can be used as materials related to COVID-19-related research in the future.

Abstract： 以典型生态脆弱区—库布齐沙漠为研究区，基于耦合度模型与耦合协调度模型，对 2008— 2017 年库布齐沙漠生态治理的生态经济系统耦合状况进行动态定量分析。结果表明：（1）2008—2017 年，库布齐沙漠生态治理的生态经济系统耦合发展呈现出较高水平的平稳态势，耦合度大多维持在 0.819 8 ~ 1 之间，且表现为先下降、后上升交替变化态势。（2）2008—2010 年，库布齐沙漠生 态治理的生态系统参数贡献度小于其社会经济系统参数贡献度，而 2011—2017 年则正好相反，且 两个系统的参数贡献度时序变化呈逐年递增趋势。（3）2008—2017 年，库布齐沙漠生态治理的生态 经济系统耦合协调度逐年增长，其耦合模式经历了从失调衰退类、过度发展类到协调发展类的变 化，且不同年份耦合模式类型差异显著。（4）2008—2012 年，系统耦合度处于高位状态，但耦合协调 度却不处于高位。2013—2017 年系统耦合度与耦合协调度变化趋势基本一致。未来库布齐沙漠 化地区应以推进生态经济化、经济生态化为关键突破点，实现区域生态经济可持续发展。

Abstract：随着高性能计算系统规模的不断扩大，节点失效愈加频发。传统的容错技术大都基于检查点 （checkpoint）方式。但是，检查点技术的开销随着系统规模的扩大而不断增加，在百亿亿次（Exaflops） 规模下其容错效率难以满足系统需求。算法失效恢复技术相比检查点方式具有更高的效率。然而，该技术依然基于停等模式。对于大规模系统，停等模式在很大程度上会影响程序的并行效率。本文提出了一种非 停等的算法级容错策略——热替换策略。在程序运行过程中若发生节点失效，不用停等恢复失效节点上的 数据，而用冗余节点替换失效节点，使计算能继续进行。终的正确结果可以通过一个线性变换求出。为 了论证方案的有效性，我们结合 MPICH 的容错特性实现了容错的 High Performance Linpack (HPL)，并评估 了方案的性能。实验结果表明，即使在小规模下，我们的方案的性能也明显优于算法失效恢复技术。
