基于MR的智能产线学具开发与应用——以SMT电路表面贴装产线为例

针对中心现有电路表面贴装技术(Surface MountedTechnology,SMT)教学环节认知负载高的问题,设计基于混合现实(Mixed Reality,MR)技术的智能产线教辅系统。目前,产线以自动化生产为主,学生无法直接观察其生产工艺及过程,后台数据不易呈现。通过MR技术将设备内部的运作状态及数据以三维影像投射在实体表面,为学生构建一种新的交互载体。通过将SMT产线的核心工艺数据从“黑盒子”中拿出来,帮助学生理解电路产品的制作原理、工艺过程等核心知识。通过“基于MR的SMT产线智能辅助教学系统”的开发与应用实例,介绍了基于本智能制造教学系统的需求分析、功能设计及开发与实施路线。

回流焊工艺对SMT器件热翘曲的影响

集成电路正在向小型化、高集成度的方向发展,回流焊工艺已成为其组装过程中的关键技术。在回流焊过程中集成电路容易发生热翘曲现象。采用阴影云纹法对PBGA1296、PBGA1024器件在不同回流焊温度、升降温速率的回流焊工艺下的热翘曲进行测量,在此基础上通过建模仿真对实验结果进行分析。结果表明,采用表面贴装技术(SMT)的BGA器件的热翘曲会随着回流焊温度的升高而增大,回流焊升降温速率较快同样会导致严重的热翘曲。实验结果与仿真结果高度一致,进而验证了仿真模型的准确性和有效性。采用实验结合有限元分析的方法为改善集成电路热翘曲提供了参考。

SMTLOC:基于多源频谱的SMT求解器缺陷定位

SMT求解器作为重要的基础软件,其存在的缺陷可能会导致依赖于它的软件功能失效,甚至带来安全事故.然而,修复SMT求解器缺陷是一个十分耗时的任务,因为开发者需要花费大量的时间和精力来理解并找到缺陷的根本原因.虽然已有许多软件缺陷定位方面的研究,但尚未有系统的工作研究如何自动定位SMT求解器缺陷.因此,提出一种基于多源频谱的SMT求解器缺陷定位方法SMTLOC.首先,对于给定的SMT求解器缺陷,SMTLOC提出一种枚举算法,用以对触发该缺陷的公式进行变异,从而生成一组不触发缺陷,但与触发缺陷的公式具有相似执行路径的证人公式.然后,SMTLOC根据证人公式的执行路径以及SMT求解器的源码信息,提出一种融合覆盖频谱和历史频谱的文件可疑度计算方法,从而定位可能存在缺陷的文件.为了验证SMTLOC的有效性,收集60个SMT求解器缺陷.实验结果表明,SMTLOC的缺陷定位效果明显优于传统的频谱缺陷定位方法,SMTLOC可以将46.67%的缺陷定位在TOP-5的文件内,定位效果提升了133.33%.

RNPS1 stabilizes NAT10 protein to facilitate translation in cancer via tRNA ac^(4)C modification

Existing studies have underscored the pivotal role of N-acetyltransferase 10(NAT10) in various cancers. However, the outcomes of protein-protein interactions between NAT10 and its protein partners in head and neck squamous cell carcinoma(HNSCC) remain unexplored. In this study, we identified a significant upregulation of RNA-binding protein with serine-rich domain 1(RNPS1) in HNSCC, where RNPS1 inhibits the ubiquitination degradation of NAT10 by E3 ubiquitin ligase, zinc finger SWIM domain-containing protein 6(ZSWIM6), through direct protein interaction, thereby promoting high NAT10 expression in HNSCC. This upregulated NAT10 stability mediates the enhancement of specific tRNA ac^(4)C modifications, subsequently boosting the translation process of genes involved in pathways such as IL-6 signaling, IL-8 signaling, and PTEN signaling that play roles in regulating HNSCC malignant progression, ultimately influencing the survival and prognosis of HNSCC patients. Additionally, we pioneered the development of TRMC-seq, leading to the discovery of novel t RNA-ac^(4)C modification sites, thereby providing a potent sequencing tool for tRNAac^(4)C research. Our findings expand the repertoire of tRNA ac^(4)C modifications and identify a role of tRNA ac^(4)C in the regulation of mRNA translation in HNSCC.

Effective extraction of polyribosomes from astrocytes enables future discoveries on translation regulation

Translation regulation is an important layer of gene expression:Generation of genome-wide expression datasets at multi-omics levels in spatial,temporal,and cell-type resolution is essential for deciphering brain complexity.Regulation of gene expression is a highly dynamic process aiming at the production of precise levels of gene products to guarantee optimal cellular function,in response to physiological cues.Speedy advances in next-generation sequencing enabled the understanding of epigenomic and transcriptomic dynamic landscapes of different brain regions along development,aging,and disease progression.However,the correlation of the“transcriptome”with protein levels is poor because numerous mRNAs are subjected to manipulation of their translation efficiency,to warrant a favorable result under certain conditions.Hence,it is widely accepted that regulation at the translation level is a vital layer of gene expression.Quantification of actively translated mRNA populations(i.e.,“translatome”)is a more reliable predictor of the“proteome”(Wang et al.,2020).

语料库翻译研究背景下的“translationese”与“翻译共性”刍议

A Comparative Study of Chinese Translations of Tagore’s Stray Birds From the Perspective of the“Three Beauties Theory”

For more than 60 years,Mr.Xu Yuanchong has been devoted to education.He has not only made remarkable achievements in translating from and into Chinese,English,French and other languages,but has also developed his own unique concept of translation.Since 1950,he has always adhered to the“Three Beauties Theory”,believing that translation should not only rely on the original text,but also realize the“beauty of meaning”,“beauty of sound”,and“beauty of form”.Based on Xu Yuanchong’s“Three Beauties Theory”,this paper takes Zheng Zhenduo’s and Feng Tang’s Chinese translations of Stray Birds as an example to explore in depth the specifics of poetry translation theory.The study summarizes the similarities and differences between these two translations in embodying the“three beauties”,providing insights into the Chinese translation techniques of philosophical prose poems.This endeavor seeks to offer valuable insights for the comparative study of Stray Birds translations。

A Descriptive Translation Study of Chinese Translation of French Musical Roméo et Juliette

This paper presents a Descriptive Translation Study(DTS)analysis of the Chinese translation of the French musical adaptation of Romeo and Juliet,titled Roméo et Juliette:de la Haineàl’Amour.Romeo and Juliet,a timeless play by Shakespeare,has captivated audiences since its premiere in 1597 and has been adapted into various forms,including stage productions,films,musicals,and operas.The focus of this study is to analyze the Chinese translation of the French musical adaptation from a DTS perspective.DTS is an approach that aims to understand the translation process and its reception in the target culture.By examining language choices,cultural references,and adaptation strategies,this study seeks to shed light on how the Chinese translation of the French musical functions within the target culture and influences the reception and interpretation of the source text.This analysis is expected to gain insights into the challenges and strategies employed in translating a musical adaptation of Romeo and Juliet into Chinese.The findings of this study will contribute to the field of translation studies and provide a deeper understanding of the complexities involved in the translation of musical works.

A Case Study of Periodical Terminologies’Mis-translations in History of Chinese Journalism by Ko Kung-chen under Analysis-Synthesis Translation Mode

From the perspective of analysis-synthesis translation mode,this paper discusses the translator’s responsibility and the translator’s role in the translation of historiography,based on the case of Ko Kung-chen’s History of Chinese Journalism.Missionary J.S.Roberts believed that translation is the logical combination of two processes of analysis and synthesis.The analysis process is characterized by understanding,emphasizing accurate understanding and professional analysis of the source text,while the synthesis process focuses on the transformation of language and culture.The two processes are dependent,forming the whole process of translation altogether.As the indisputable subject of translation,the translator should assume his own subjective responsibility in the two processes.The translator should be responsible for the fact and professional academics in the analysis process,and language and culture and translation itself in the synthesis process,playing the role of a reviewer,disseminator and translator to ensure that the translation text would be correct,accurate and professional so as to realize the value of himself and translation.

The Translation of Allusions in Political Discourse:An Intertextuality Perspective

drawn from ancient classics are the treasures of traditional Chinese culture.The allusions used in Xi Jinping:The Governance of China illustrate a distinctive feature of political discourse,and the publication of its English version provides a valuable opportunity for the study of allusions in translated political discourse.With the English translations of 241 allusions collected from two volumes of the book,we classified these allusions into three categories of history,culture,and literature based on their original sources.Then we analyzed the strategies used in translating the allusions,and provided typical examples to illustrate the use of such translation strategies for each category.Finally,we tried to account for the use of these strategies in light of the intertextuality theory.
