A new dynamic multi-dimensional index structure called RSR-tree is proposed, in which splitting operations of leaf nodes and non-leaf nodes are performed separatively. RSR-tree retains the sequence ordering of index records in a leaf node of RS-tree and thus reduces the addressing time cost of disk access while reading data files. In addition, it integrates the characteristic of reducing the ov...

SUMMARY ClaNC (classification to nearest centroids) is a simple and an accurate method for classifying microarrays. This document introduces a point-and-click interface to the ClaNC methodology. The software is available as an R package. AVAILABILITY ClaNC is freely available from http://students.washington.edu/adabney/clanc

The isolation-with-migration (IM) model is a common tool to make inferences about the presence of gene flow during speciation, using polymorphism data. However, Becquet and Przeworski (2009) report that the parameter estimates obtained by fitting the IM model are very sensitive to the model’s assumptions – including the assumption of constant gene flow until the present. This paper is concerned...

During the 2014-2017 period, wheat samples were collected from discoloured spikes affected by Fusarium head blight (FHB) 20 locations in Serbia. After isolation, fungi cultivated on potato dextrose agar (PDA) at 25oC for 7 days. Based situ identification PDA, 36 isolates of section Liseola selected further analyses. The pathogenicity all was confirmed leaves. virulence determined measuring leng...

Purpose: To assess the effects of ligustrazine on progression hypoxia-reoxygenation (H/R), and explore possible role miR-211 in myocardial ischemia-reperfusion (I/R) injury identify its potential targeting gene. Methods: The level H/R-induced cells was detected by quantitative polymerase chain reaction. CCK-8, flow cytometry (FCM), Western blot assays were performed to examine effect USP47 remi...

A class of probability models for inference about alterations in gene expression is reviewed. The class entails discrete mixing over patterns of equivalent and differential expression among different mRNA populations, continuous mixing over latent mean expression values conditional on each pattern, and variation of data conditional on latent means. An R package EBarrays implements inference cal...

BACKGROUND It is long known within the mathematical literature that the coefficient of determination R(2) is an inadequate measure for the goodness of fit in nonlinear models. Nevertheless, it is still frequently used within pharmacological and biochemical literature for the analysis and interpretation of nonlinear fitting to data. RESULTS The intensive simulation approach undermines previous...

OpenGL is a cross-platform library for 3D rendering. In this paper I will describe RGL, an R package providing a simplified interface to it. The style of the interface follows that of the older S or R plotting functions, with some differences. In particular, it is possible for the user to manipulate objects on the screen, and programmatically to change the appearance or content of the
