Most RDBMSs maintain a set of histograms for estimating the selectivities of given queries. These selectivities are typically used for costbased query optimization. While the problem of building an accurate histogram for a given attribute or attribute set has been well-studied, little attention has been given to the problem of building and tuning a set of histograms collectively for multidimens...

Background: We have recently introduced a predictive framework for studying gene transcriptional regulation in simpler organisms using a novel supervised learning algorithm called GeneClass. GeneClass is motivated by the hypothesis that in model organisms such as Saccharomyces cerevisiae, we can learn a decision rule for predicting whether a gene is upor down-regulated in a particular microarra...

in addition to drawing attention to the individual and social responsibilities, the holy qur’ān has also talked about the importance of the social groups and emphasized on the efficacy of groups on individuals and other groups and the impressionability of those individuals and other groups. in the meantime, the reference groups have a significant role in the development and degeneration of indi...

We develop and discuss a methodology for batch-level analysis of hyperspectral stimulated Raman scattering (hsSRS) data sets of human meibum in the CH-stretching vibrational range. The analysis consists of two steps. The first step uses a training set (n=19) to determine chemically meaningful reference spectra that jointly constitute a basis set for the sample. This procedure makes use of batch...

It is widely recognized that many African economies are being transformed by rapid economic growth driven largely by rising demand for the abundant natural resources scattered across the African continent. I critically review the mainstream gamechanging dynamics driving this process, with special reference to a set of influential policy-oriented documents. This is followed by an analysis of les...

In 2015, the Research and Instructional Services Unit of Meyer Library at Missouri State University was challenged to update rethink current service model space. We had been operating in a traditional reference model, including large, walkup desk that staffed primarily by faculty librarians. After reviewing literature, it decided some form reference/research point should be kept but completely ...
