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.

IGF-PI3K-Akt信号通路在生理性心肌肥大中的作用研究进展

心肌肥大是心肌细胞对多种刺激因素的复杂反应。心肌肥大可以分为三种:心肌的正常生长、运动诱导生理性心肌肥大和病理性心肌肥大。近年来,研究表明心肌的正常生长以及运动诱导的心肌生理性肥大,主要是通过IGF-PI3K-Akt信号通路进行信号转导。本文就IGF-PI3K-Akt信号转导通路的结构特点、调节过程作一综述。     

苯在Ru-Zn/Ru（0001）合金表面上的吸附——密度泛函研究

为了理解苯在Ru-Zn合金催化剂上的部分加氢催化机理,采用密度泛函方法对苯在Ru-Zn/Ru（0001）面上的吸附进行理论研究。计算结果表明,当苯的碳原子或者共轭双键直接位于表面Zn原子的atop位时,其吸附热较Ru（0001）面上的类似吸附状态下降约60%.Zn原子与苯环C原子之间的排斥作用导致苯环的成键轨道与表面Ru原子的价层轨道之间的空间对称性下降,从而不利于苯与合金表面的键合。当吸附位离开Zn原子时,邻近Zn原子对于苯的吸附基本没有影响。
