This study presents results for the estimation of impinging waves’ delay, azimuth, elevation and complex amplitude in synthetic and real time-invariant mobile radio environments, using the Space-Alternating Generalized Expectation-Maximization (SAGE) algorithm. The minimum separation between two waves needed to obtain acceptable estimations is investigated in some particular cases. Experimental...

Serial Analysis of Gene Expression, or SAGE, is a technology of measuring the expression levels of the mRNA transcripts. The result of a SAGE experiment is reported as a SAGE library, which contains the counts of various short segments (tags) of the cDNA clones. Through a close examination of the SAGE experiment protocol, we derive a new statistical model for the SAGE data, and give new tests f...

A comparison study of short SAGE versus GeneChip and long SAGE was conducted to determine if data were interchangeable between the techniques. Although SAGE and Affymetrix chip expression levels showed a significant correlation using the set of genes for which there was reliable and unambiguous mapping from tag-to-gene identification, correlation coefficients were low (0.51 for the Spearman's c...

A gene's expression pattern provides clues to its role in normal physiology and disease. To provide quantitative expression levels on a genome-wide scale, the Cancer Genome Anatomy Project (CGAP) uses serial analysis of gene expression (SAGE). Over 5 million transcript tags from more than 100 human cell types have been assembled. To enhance the utility of this data, the CGAP SAGE project create...

A Maximum Likelihood ML method for joint estimation of amplitude phase time delay and data demodulation in a single user direct sequence spread spectrum communica tion system is developed The likelihood function is an alytically intractable so a recursive estimation algorithm is considered The Expectation Maximization EM algo rithm has been used in similar problems however in this case it is no...

FoxA transcription factors play major roles in organ-specific gene expression, regulating, for example, glucagon expression in the pancreas, GLUT2 expression in the liver, and tyrosine hydroxylase expression in dopaminergic neurons. Organ-specific gene regulation by FoxA proteins is achieved through cooperative regulation with a broad array of transcription factors with more limited expression ...

Serial Analysis of Gene Expression (SAGE) is becoming a widely used gene expression profiling method for the study of development, cancer and other human diseases. Investigators using SAGE rely heavily on the quantitative aspect of this method for cataloging gene expression and comparing multiple SAGE libraries. We have developed additional computational and statistical tools to assess the qual...

The Mouse SAGE Site is a web-based database of all available public libraries generated by the Serial Analysis of Gene Expression (SAGE) from various mouse tissues and cell lines. The database contains mouse SAGE libraries organized in a uniform way and provides web-based tools for browsing, comparing and searching SAGE data with reliable tag-to-gene identification. A modified approach based on...

this experiment was conducted with the objective of evaluating the performance sage (salvia officinalis l.) in different agroecology of ethiopia for morpho-agronomic and chemical traits at wondo genet, hawassa, qoqa and holleta for two years from 2011/2012 to 2012/2013 cropping seasons. data on plant height, branch number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground bio...
