The harmonic decomposition reconstruction for the exponential radon transform

The exponential Radon transform, a generalization of the Radon transform, is defined and studied as a mapping of function spaces. It is represented in terms of Fourier transform of its domain and range, and this leads to the harmonic decomposition reconstruction. The results are similar results of Tretiak and Metz. Foundation item: Supported by the National Natural Science Foundation of China (No. 19971064), Key Project of Science and Technology of Hubei Province Education Committee. Biography: Wang Jin-ping (1963-), male, Ph.D. candidate, research direction: numberical solution of singular integral equation and integral transformation etc.     

知识发现中一种变化趋势模型的算法研究

在时序数据库中,有许多成熟的技术和方法用来对布尔型属性之间的关系进行挖掘,但对于数值型属性变化趋势关联关系的研究却不是很多.本文提出了一种数值型属性变化趋势的研究模型QMP(QuantityMovementPattern),依据该模型可利用数据挖掘算法发现不同数值型属性之间变化趋势之间的关系.文中分析了该模型的几种实现算法,并给出了一种快速实现算法及实验数据.

上皮生长因子预防心脏术后心包粘连的实验及临床研究

目的探讨上皮生长因子(EGF)对心脏术后心包粘连的预防作用.方法术中对犬心包内喷洒上皮生长因子3个月后,观察心包粘连情况;选先天性心脏病、房缺及室缺病人40例,术中心包内喷洒上皮生长因子,术后6个月、12个月经CT检查,判定心包粘连、增厚结果.结果在动物实验和临床研究中,实验组粘连程度显著低于对照组(P<0.01).结论 EGF心包内应用有明显预防心脏术后心包粘连的作用.

生态治理中政府部门代理人道德风险因素分析

针对我国生态环境治理存在政府部门代理人道德风险的社会现象,认为影响代理人个人道德风险的因素主要有诚实履约的正常收益、道德风险行为被发现的概率、贴现因子、道德风险行为的额外收益以及道德风险行为被发现后的次优收益,并且以预期收益为目标建立数学模型,分析政府部门代理人个人道德风险行为动机与影响因素之间的关系。进一步扩展模型,讨论了社会监督成本以及随机因素的影响作用。最后,提出了相关的监督、激励及协作策略。

An ERP study for the degrees of the difficulty in visual search

The present study mainly probed the relationships between ERP components and the degrees of difficulty in visual search. Three experimental and one controlled conditions were randomly selected. Results showed that the P1, N1, and P2 amplitudes and latencies had no significant differences among the three experimental and one controlled conditions, and the ERP waveforms of low perceptual load of visual search were different from that of high perceptual load. These results might indicate that the latencies and amplitudes of initial P1, N1 and P2 in high and low perceptual load conditions were almost the same. The ERP waveforms of parallel search were very different from that of serial search, and the ERP waveforms of serial search were very similar. The P3 amplitudes increased as the degrees of the difficulty in visual search decreased.
