Constrained ordination methods include constrained (or canonical) correspondence analysis (CCA), redundancy analysis (RDA) and distancebased redundancy analysis (db-RDA). Constraining means that ordination only shows the community variation that can be explained by external environmental variables or constraints. This document describes the following basic concepts (1) usage of constrained ordi...

OBJECTIVE To evaluate, using conventional in vitro procedures, the abrasivity, enamel polishing properties, and stain removal effectiveness of various commercial dentifrices that have a variety of compositions and are marketed for cleaning, whitening, and/or polishing capabilities, and to examine their relationships between stain removal and abrasivity. METHODS The Relative Dentin Abrasivity ...

Recently, the US network of weather surveillance radars (NEXRAD) was upgraded with the Open Radar Data Acquisition (ORDA) subsystem which includes new receivers, signal processors, and control subsystems (Patel and Macemon 2004). Before this upgrade, the legacy RDA estimated the spectrum width using the standard pulse-pair technique. The new signal processor implements a similar spectrum width ...

This paper considers a wide spectrum of regularized stochastic optimization problems where both the loss function and regularizer can be non-smooth. We develop a novel algorithm based on the regularized dual averaging (RDA) method, that can simultaneously achieve the optimal convergence rates for both convex and strongly convex loss. In particular, for strongly convex loss, it achieves the opti...

Resource Description and Access (RDA) is a new standard for describing all types of resources. Columbia University, the University of Chicago, and the University of Illinois at UrbanaChampaign evaluated the guidelines by means of the Dublin Core element set during the U.S. National Libraries RDA Test, held from October to December 2010. This paper speaks to the issues which emerged during the t...

Epidemiological evidence suggests that infection is involved in the etiology of common acute lymphoblastic leukemia, either by stimulating an inappropriate immune response or in the form of a classical transforming agent. In an attempt to elucidate the role that infection is playing in this disease, we used representational difference analysis (RDA) to examine tumor samples for the presence of ...
