Effects of self evaluation on late ERP components

High-density event-related potentials (ERPs) were measured when participants were required to evaluate oneself, significant others (father and mother) and the most familiar public figures (Lei Feng and Jiang Qing) based on trait adjectives. There were three referential conditions and a non-referential control condition including self-evaluation (SE), significant other-evaluation (SOE), general other-evaluation (GOE), and semantic positivity-evaluation (SPE). The behavioral data showed that RTs to GOE condition were longer than the other three conditions. Scalp ERP analysis revealed that (1) SPE condition elicited a more negative N2 than SE condition, which was associated with inhibition of responses; (2) SE condition elicited a more positive P300 than SPE condition, which was an index of attention to self-relevant stimuli; (3) there was no difference on the amplitude and latency of P300 between SE and SOE conditions, which reflected that the concept of “self” included intimate others (e.g., father and mother) in Chinese culture.     

Method of Homomorphic Encryption

The existing homomorphie eneryption scheme is based on ring of the integer, and the possible operators are restricted to addition and multiplication only. In this paper, a new operation is defined Similar Modul. Base on the Similar Modul, the number sets of the homomorphic encryption scheme is extended to real number, and the possible operators are extended to addition, subtraction, multiplication and division. Our new approach provides a practical ways of implementation because of the extension of the operators and the number sets.

改善20CrMnTiH淬透性的研究

莱钢特钢厂20CrMnTiH钢材成分波动较大,淬透性带HRC8～10,范围较大,制约了齿轮钢质量的进一步提高.通过研究,发现铸坯中心偏析尤其是碳偏析为主要问题.通过工艺优化采取各项措施,尤其增加电磁搅拌后,中心碳偏析得到明显改善;C控制在0.19%～0.20%的炉次达到了95.6%;淬透性带控制在HRC6内的达到了92.1%;在HRC4内的达到了86.2%;提高了产品质量,满足了用户需求.     

污泥营养土对菊花营养生长和开花的效应

采用三种菊花的盆栽试验，探讨不同配比的污泥营养土对三种菊花冠径、地径和生物量、叶绿素含量、花期、开花量等的影响，结果表明：2份污泥＋14份塘土＋3份炉渣＋3份谷壳灰和3份污泥＋3份炉渣＋3份谷壳灰的污泥营养土配方，能显著促进菊花的营养生长，延长花期，增加花量，施用效果最好。

偏硼酸钠与镁和氢反应的硼氢化钠生成

高的氢压和反应温度有利于片硼酸钠与镁和氢反应生成硼氢化钠，但温度接近镁的熔点时不利于硼氢化钠的生成。在反应物中添加铁、镍和钴将加速硼氢化钠的生成，而铜的加入却阻碍硼氢化钠的生成。
