论何其芳现代格律诗的出发点

何其芳的"现代格律诗"提法,有两个纠缠在一起的出发点:其一它是一种很强的意识形态行为,承担了新政权在文化领域中的规训要求;其二它是一种被召唤的诗人个体行为。梳理清楚"现代格律诗"的出发点,会发现一个综合的何其芳。     

Estimating the Upper Support Point in Deconvolution

Abstract.  We consider estimation of the upper boundary point F ⁻¹ (1) of a distribution function F with finite upper boundary or 'frontier' in deconvolution problems, primarily focusing on deconvolution models where the noise density is decreasing on the positive halfline. Our estimates are based on the (non-parametric) maximum likelihood estimator (MLE) of F . We show that (1) is asymptotically never too small. If the convolution kernel has bounded support the estimator (1) can generally be expected to be consistent. In this case, we establish a relation between the extreme value index of F and the rate of convergence of (1) to the upper support point for the 'boxcar' deconvolution model. If the convolution density has unbounded support, (1) can be expected to overestimate the upper support point. We define consistent estimators , for appropriately chosen vanishing sequences ( β _n ) and study these in a particular case.

邓小平理论的逻辑起点研究之我见

关于邓小平理论的逻辑起点,有多种不同的观点,比如：社会主义的本质论、社会主义的初级阶段论、真理标准论。其实,一个单一的逻辑起点是很难统摄邓小平理论所涉及到的方方面面的,我们应该分别为邓小平理论所涉及到的不同方面找出不同的逻辑起点。     

An online copy number variant detection method for short sequencing reads

The availability of the next generation sequencing (NGS) technology in today's biomedical research has provided new opportunities in scientific discovery of genetic information. The high-throughput NGS technology, especially DNA-seq, is particularly useful in profiling a genome for the analysis of DNA copy number variants (CNVs). The read count (RC) data resulting from NGS technology are massive and information rich. How to exploit the RC data for accurate CNV detection has become a computational and statistical challenge. We provide a statistical online change point method to help detect CNVs in the sequencing RC data in this paper. This method uses the idea of online searching for change point (or breakpoint) with a Markov chain assumption on the breakpoints loci and an iterative computing process via a Bayesian framework. We illustrate that an online change-point detection method is particularly suitable for identifying CNVs in the RC data. The algorithm is applied to the publicly available NCI-H2347 lung cancer cell line sequencing reads data for locating the breakpoints. Extensive simulation studies have been carried out and results show the good behavior of the proposed algorithm. The algorithm is implemented in R and the codes are available upon request.     

晚清历史“传闻素材”中的史学意蕴

历史"传闻素材",从它的史料主要承载门类来看,在"正则"文献中所涉及者,有的被明确提示或被暗示出来,有的则在文本中被完全"异化",从形式上再也显不出传闻的属性;在稗野轶闻类史料中,自有其最为集中和醒目的反映;在"口述历史"类资料中,一般也有比较典型的体现。从史学理念的层面说,因为历史传闻当时具有真伪虚实莫辨的模糊性特点,故需要具备强化考辨的理念;因为历史传闻的真伪虚实未必都能考辨清楚,故需要抱有适当存疑的理念;因为历史传闻不乏在具体情节上失实而大致指向上符实的情况,故应当培养体悟神韵的理念;因为传闻入史对著述的文体风格会发生连带的影响,故不应排斥助益灵动的理念。这些,都是科学地认识和妥当地运用传闻素材所很应注意的。     

让审美理论在实践中走向澄明之境－－兼评《通向澄明之境》

在当今美学日益边缘化的境况之下,要发展和推进美学,就必须以实践作为逻辑起点,让审美理论在实践中走向澄明之境。这条建构当代中国美学的道路就是在实践中的人生论美学与审美人类学的统一。     

室内设计中点线面要素的应用研究

“设计”是一个经常使用的概念,设计是在明确目的指导下的有意识的创造。室内设计是人们在满足自身需求的基础上对建筑的内部空间进行合理的功能划分、技术创新,以及艺术上的审美观的综合设计。点、线、面是作为构成抽象形态造型的要素,空间构成的基本单位。在室内设计中,点、线、面处处可见,它们之间相互影响、相互陪衬、相互烘托、相互存在、相互作用。文章从室内设计的风格、室内陈设的研究出发,对室内设计中点、线、面的运用进行思考分析。
