基于韵律变换的情感说话人识别

为了解决由情感变化引起的说话人识别性能下降问题,提出了一种新的情感说话人识别系统．首先,通过引入情感识别作为前端处理模块,对中性语音和情感语音进行分类．然后,对情感语音进行韵律修正,分别采用高斯归一化、高斯混合模型（GMM）和支持向量回归（SVR）等方法建立情感语音和中性语音的基频映射规则,并根据平均线性变化率对时长进行了修正．最后,对韵律修正后的情感语音进行识别．实验结果表明,提出的情感说话人识别系统可以有效地提高情感说话人识别的性能,识别率相比传统方法有了显著的提高．并且通过基频和时长修正的情感语音更接近于中性语音．     

Crossover Literature and Abjection: Geraldine McCaughrean’s <Emphasis Type="Italic">The White Darkness</Emphasis>

This article provides a close reading of Geraldine McCaughrean’s award-winning novel, The White Darkness. It argues that this is a key text in the increasing debate about ‘crossover’ literature. Whereas, traditionally, adolescent books were seen to offer compensatory fantasies to the adolescent reader, McCaughrean’s text goes beyond this, exploring adolescence in deeper terms: not simply as an age-defined period but as a time when the traditional coordinates of the self are thrown into crisis, or become destabilized (as an ‘open psychic structure’, as Kristeva puts it). Adopting such a psychoanalytical approach, it is argued, we can begin to understand this book’s appeal (and others like it) to adolescent and adult alike; that is, it stages a shift from an imaginary identification with a stable self to a more realistic, albeit less secure recognition of the flimsiness of identity. The white wastes of Antarctica provide the perfect backdrop for this confrontation with the ungraspable Real.

基于计量经济模型假设检验问题的研究

近年来．对于计量经济模型假设检验问题的研究不多见，本文通过考察计量经济模型的参数假设检验及回归方程假设检验过程，分析了回归参数检验的t统计量显著性的影响因素，分析了回归方程总体显著性F检验与拟舍优度R-平方的关系，说明了较低的R-平方，并非意味着方程没有用，参数的t检验和回归方程的F检验仍可能显著。     

Molecular Basis of Cystic Fibrosis Disease: An Indian Perspective

Cystic fibrosis is a common autosomal recessive disorder usually found in population of white Caucasian descent. Now it is well documented the presence of CF disease in India with the advancement of laboratory testing. As once it was thought non existence of this disease in our population. Most of the phenotype of CF disease was in accordance of western population. Genetic analysis of CFTR gene in Indian CF patients revealed that most common mutation was delta F508 mutation. However, it was less than Caucasian population. CFTR mutations are also a causative factor in the pathogenesis of male infertility due to obstructive azoospermia. There are two most common mutation viz. IVS8-T5 and delta F508 which are responsible for congenital absence of vas deferens in male infertility patients. Elevated levels of sweat chloride at two occasions along with the presence of two mutations in CFTR gene was gold standard method for diagnosis of CF disease. It is noteworthy here that due to magnitude of Indian population, the total CF disease load would be more than many European countries. Clinical data demonstrate the prevalence of both classical and genetic form of CF in India.
