Fundamental Components of Attention A mechanistic understanding of attention is necessary for the elucidation of the neurobiological basis of conscious experience. This chapter presents a fra... Knudsen,I Eric - 《Annual Review of Neuroscience》 被引量: 1208发表: 2007年 The components of attention A...
This chapter presents a framework for thinking about attention that facilitates the analysis of this cognitive process in terms of underlying neural mechanisms. Four processes are fundamental to attention: working memory, top-down sensitivity control, competitive selection, and automatic bottom-up ...
It extracts the fundamental structure of the data without the need to build any model to represent it. This ‘summary’ of the data is arrived at through a process of reduction that can transform the large number of variables into a lesser number that are uncorrelated (i.e. the ‘principal...
Fundamental Study of Analysis and Evaluation of Volatile Fragrance Components of Buvaria FlowerThe volatile fragrance components of Buvaria flower were isolated by dynamic headspace sampling method and analyzed with GC and GC-MS. Analysis showed that the headspace extract contained 30 volatile compounds ...
Miller 摘要: Analysis with "communications modes" between volumes allows rigorous general limits on imaging and communications channels. Together with a new multiple scattering theorem, this approach also leads to fundamental limits to optical components. DOI: 10.1364/FIO.2010.FThT1 年份: 2010 ...
Principal component analysis (PCA) is fundamental in many pattern recognition applications. Much research has been performed to minimize the reconstruction error in L1-norm based reconstruction error minimization (L1-PCA-REM) since conventional L2-norm based PCA (L2-PCA) is sensitive to outliers. Rec...

In short, the balance sheet is afinancial statementthat provides a snapshot of what a company owns and owes, as well as the amount invested by shareholders. Balance sheets can be used with other important financial statements toconduct fundamental analysisor calculate financial ratios. Key Takeaway...
An analysis of perturbing factors influencing the motion of a navigation satellite (NS) is carried out, and the degree of influence of each factor on the GLONASS orbit is estimated. It is found that fundamental components of the Earth's rotation parameters (ERP) are one substantial factor com...
Determining the number of components in a linear mixture model is a fundamental problem in many scientific fields, including chemometrics and signal processing. In this paper we present a new method to automatically determine the number of components from a limited number of (possibly) high dimension...
