Intergenic mapping by a sorbose selection technique.

Ongoing purifying selection on intergenic spacers in group A streptococcus.

Bacterial intergenic spacers are non-coding genomic regions enriched with cis-regulatory elements for gene expression. A population genetics approach was used to investigate the evolutionary force shaping the genetic diversity of intergenic spacers among 13 genomes of group A streptococcus (GAS). Analysis of 590 genes and their linked 5' intergenic spacers showed reduced nucleotide diversity in...

Phenotypic Assay on L - Sorbose

BIOCHEMISTRY. For the article ‘‘Kernel energy method: Application to insulin,’’ by Lulu Huang, Lou Massa, and Jerome Karle, which appeared in issue 36, September 6, 2005, of Proc. Natl. Acad. Sci. USA (102, 12690–12693; first published August 24, 2005; 10.1073 pnas.0506378102), the authors note an error in a funding acknowledgment: ‘‘L.M. thanks the National Institutes of Health for National In...

A NEW TECHNIQUE FOR POSTSAMPLE MODEL SELECTION AND VALIDATION by

The model selection and Granger-causality literatures have generally focused on insample rather than postsample hypothesis testing. In large part this is due to the fact that feasible postsample model validation periods are usually quite short, whereas large-sample methods are ordinarily required in order to deal with the serial correlation and crosscorrelation typically found in postsample for...

Project Selection by Using a Fuzzy TOPSIS Technique

Selection of a project among a set of possible alternatives is a difficult task that the decision maker (DM) has to face. In this paper, by using a fuzzy TOPSIS technique we propose a new method for a project selection problem. After reviewing four common methods of comparing investment alternatives (net present value, rate of return, benefit cost analysis and payback period) we use them as cri...
