山西省入境旅游市场竞争态及转移分析

山西是全国旅游资源大省之一，拥有众多品位极高的旅游资源，但强大的资源优势并没有很好的转化为经济优势，这些年入境旅游业绩一直位居全国中下游．为了尽快改变这种状况，使山西入境旅游业得以加速发展，分析研究其市场状况就是很有必要的了．本文借助市场竞争态模型对2000年～2002年和2003年～2005年山西省入境旅游客源市场的竞争态势进行对比分析，并对山西省入境旅游市场竞争态进行动态分析．在分析的基础上，提出了拓展山西入境旅游市场的几点建议．     

急倾斜厚煤层掩护支架采煤法机械化问题的探讨

掩护支架采煤法是开采急倾斜厚煤层的有效方法之一,但回采工艺大多使用炮采。为进一步扩大急倾斜厚煤层掩护支架采煤法的适用范固,大幅度地提高技术经济效果,必须实现掩护支架下的采煤机械化。本文在总结分析国内外有关经验、资料的基础上,对掩护支架结构型式的改进和采煤机械化问题进行了初步的探讨,提出了设想方案。     

Recombination and linkage disequilibrium in Arabidopsis thaliana

Linkage disequilibrium (LD) is a major aspect of the organization of genetic variation in natural populations. Here we describe the genome-wide pattern of LD in a sample of 19 Arabidopsis thaliana accessions using 341,602 non-singleton SNPs. LD decays within 10 kb on average, considerably faster than previously estimated. Tag SNP selection algorithms and 'hide-the-SNP' simulations suggest that genome-wide association mapping will require only 40%-50% of the observed SNPs, a reduction similar to estimates in a sample of African Americans. An Affymetrix genotyping array containing 250,000 SNPs has been designed based on these results; we demonstrate that it should have more than adequate coverage for genome-wide association mapping. The extent of LD is highly variable, and we find clear evidence of recombination hotspots, which seem to occur preferentially in intergenic regions. LD also reflects the action of selection, and it is more extensive between nonsynonymous polymorphisms than between synonymous polymorphisms.

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.     

变时滞神经网络指数稳定性条件

基于时滞细胞神经网络(DCNNs)在图像处理等领域的广泛应用,有关它的研究引起了越来越多学者和专家的关注.早期DCNNs稳定性的结果大多由网络权矩阵的分量构成的代数不等式来表示.运用Lyapunov-Krasovskii泛函的方法,研究了DCNNs的指数稳定性,所得充分条件以矩阵的(半)正定形式出现,在实际应用中更加便于验证.与文献中的结果相比较,所得判据适用范围更广.     

量子退相干解释的再思考

量子测量退相干解释,在解决量子测量难题上正在取得进展。但量子测量退相干解释的具体模型,被测系统与宏观仪器所形成的纠缠态,在退相干解释理论体系中逻辑上并不自恰,退相干解释的应用模型仍存在重新建立的必要。
