To standardize the tea export market and guarantee interest of consumers, adulteration problem in Taiping Houkui should be eliminated. In this study, a screening scheme comprising chemometrics statistical analysis was proposed to estimate geographical origin tea. A total 11 metal ions were detected by performing chemometric experiment. The key variables that can used identify screened using lea...

Multinomial logistic regression is preferred in the classification of multicategory response data for its ease interpretation and ability to identify associated input variables each category. However, identifying important high-dimensional poses several challenges as majority are unnecessary discriminating categories. Frequently used techniques include regularisation such Least Absolute Selecti...

A number of methods have been developed for modeling the evolution of a quantitative trait on a phylogeny. These methods have received renewed interest in the context of genome-wide studies of gene expression, in which the expression levels of many genes can be modeled as quantitative traits. We here develop a new method for joint analyses of quantitative traits within- and between species, the...

PURPOSE Restoration of endodontically treated teeth using fiber posts in a one-stage procedure gains more popularity and aims to create a secondary monoblock. Data of detailed analyses of so called "post-and-core-systems" with respect to morphological characteristics of the resin-dentin interface in combination with bond strength measurements of fiber posts luted with these materials are scarce...
