Abstract Body size influences the effect of individuals and assemblages on ecosystem functioning defines how they respond to changes. We evaluated body structure fish functional groups human modifications at catchment, riparian local scales in 40 streams Pampa grasslands, southern Brazil. To describe structure, we calculated mean, coefficient variation, skewness, kurtosis, using individual biom...

Relative importance is a topic that has seen a lot of interest in recent years, particularly in applied work. The R package relaimpo implements six different metrics for assessing relative importance of regressors in the linear model, two of which are recommended averaging over orderings of regressors and a newly proposed metric (Feldman 2005) called pmvd. Apart from delivering the metrics them...

Yielding precise search answer set, information extraction of the Web and proposing more accurate ranking methods of Web pages are among the open issues in search engines research area due to the ever-growing and dynamic nature of the World Wide Web. Since the performance of any Web search engine regarding the quality of the search answer set and the appropriate ranking technique is highly depe...

OBJECTIVES Population ageing and the increasing burden of chronic conditions challenge traditional metrics of assessing the efficacy of health care interventions and as a consequence policy and planning. Using chronic heart failure (CHF) as an exemplar this manuscript seeks to describe the importance of patient-reported outcomes to inform policy decisions. METHODS The method of an integrative...

Processors used in portable systems must provide highly energy-efficient operation, due to the importance of battery weight and size, without compromising high performance when the user requires it. The user-dependent modes of operation of a processor in portable systems are described and separate metrics for energy efficiency for each of them are found to be required. A variety of well known l...

This paper highlights the importance of identifying and implementing Power Usage Effectiveness metrics for measuring the performance and efficiency of data center to accomplish cost and operational savings. The research highlighted in this paper emphasizes the importance of green data centers to meet business industry requirements and to reduce the effects of global warming. The results clearly...

Microarrays have become a routine tool for biomedical research. Data quality assessment is an essential part of the analysis, but it is still not easy to perform objectively or in an automated manner, and as a result it is often neglected. Here, we compared two strategies of array-level quality control using five publicly available microarray experiments: outlier removal and array weights. We a...
