语句拼音-汉字转换的智能处理机制分析

语句拼音- 汉字转换是中文信息处理研究的一个重要方面,是键盘汉字输入和语音输入的核心技术,其主要特征是对动态输入的拼音串进行词法分析,给出所有可能的汉语句子,然后对这些汉语句子根据上下文环境进行句法分析和语义分析,动态调整句子中的字词,输出最佳结果。近年来,语句拼音- 汉字转换系统大量应用了人工智能技术和机器翻译的理论,以期提高系统转换的准确率和增强系统的智能处理功能。本文分析了语句拼音- 汉字转换系统所采用的核心技术,即知识支持、自动分词和动态调整等,讨论了语句拼音- 汉字转换的处理方法和过程,知识库的组成结构,用于拼音串自动分词的算法和实现,音字转换中动态调整的概率模型等,本文还分析了现有语句拼音- 汉字转换系统在拼音串自动分词和音字转换的动态调整中发生错误的原因,并提出了改进方法。

Hybrid accident simulation methodology using artificial neural networks for nuclear power plants

A hybrid accident simulation methodology for nuclear power plants is proposed to enhance the capabilities of compact simulator by introducing artificial neural networks. Two neural networks are trained with the target values obtained from the analyses of detailed computer codes and trained results are combined with the compact simulator to perform the following roles: (i) compensation for inaccuracies of a compact simulator occurring from simplified governing equation and reduced number of physical control volumes, and (ii) prediction of the critical parameter usually calculated from the sophisticated computer code: the autoassociative neural network improves the computational results of the compact simulator up to the accuracy level of detailed best estimate computer code, while the backpropagation neural network predicts the minimum departure from nucleate boiling ratio (DNBR). Simulations are carried out to verify the applicability of the proposed methodology for the loss of flow accidents and the results show that the neural networks can be used as a complementary tool to improve the results of a compact simulator.

Daily recovery experiences: The role of volunteer work during leisure time.

This study focused on the role of volunteer work for daily recovery from work. In a 1-week diary study with 166 employees, we assessed the amount of time spent on volunteer work during leisure time, and the recovery facets of psychological detachment from work (i.e., mentally switching off from work), mastery experiences (i.e., pursuing challenging activities), and community experiences (i.e., cultivating relationships) every day before participants went to bed. Results from hierarchical linear modeling (n = 529 days) showed volunteer work during leisure time to be positively related to mastery experiences and community experiences suggesting volunteer work to contribute to successful recovery by creating new resources.

Bystander effect in human hepatoma HepG2 cells caused by medium transfers at different times after high-LET carbon ion irradiation

Although radiation-induced bystander effects have been well documented in a variety of biological systems, whether irradiated cells have the ability to generate bystander signaling persistently is still unclear and the clinical relevance of bystander effects in radiotherapy remains to be elucidated. This study examines tumor cellular bystander response to autologous medium from cell culture irradiated with high-linear energy transfer (LET) heavy ions at a therapeutically relevant dose in terms of clonogenic cell survival. In vitro experiments were performed using human hepatoma HepG2 cell line exposed to 100 keV/μm carbon ions at a dose of 2 Gy. Two different periods (2 and 12 h) after irradiation, irradiated cell conditioned medium (ICCM) and replenished fresh medium were harvested and then transferred to unirradiated bystander cells. Cellular bystander responses were measured with the different medium transfer protocols. Significant higher survival fractions of unirradiated cells receiving the media from the irradiated cultures at the different times post-irradiation than those of the control were observed. Even replenishing fresh medium for unirradiated cells which had been exposed to the ICCM for 12 h could not prevent the bystander cells from the increased survival fraction. These results suggest that the irradiated cells could release unidentified signal factor(s), which induced the increase in survival fraction for the unirradiated bystander cells, into the media sustainedly and the carbon ions triggered a cascade of signaling events in the irradiated cells rather than secreting the soluble signal factor(s) just at a short period after irradiation. Based on the observations in this study, the importance of bystander effect in clinical radiotherapy was discussed and incorporating the bystander effect into the current radiobiological models, which are applicable to heavy ion radiotherapy, is needed urgently.     

Investigation of a non-explosive directional roof cutting technology for self-formed roadwayOA

Traditional explosives have characteristics of high risk, large vibration, and poor directional fracturing.Consequently, an instantaneous expander with a single crack surface(IESCS), which is a novel nonexplosive directional rock-breaking technique, has been developed. The directional roof-cutting mechanism of the IESCS method, driven by high-pressure gas, was theoretically analyzed. Laboratory experiments and numerical simulations proved the directional slitting effect of the IESCS method to be...
