allelopathic plants, because of reduction in herbicide uses, are important in weed management. the allelopathic effects of sage salvia officinalis and white wormwood artemisia sieberi water extract were evaluated on germination and seedling growth of redroot pigweed amaranthus retroflexus at concentration of 0, 5, 10, 15, and 20% in controlled conditions. anova revealed that the extract concent...

In this paper, the serial interference cancellation (SIC) technique and the frequency domain SAGE (FD-SAGE) algorithm are jointly used to detect and estimate the radio channel parameters of interest. The implementation of the SAGE algorithm in the frequency domain is novel. Furthermore, the parallel interference cancellation (PIC) technique in the standard SAGE algorithm is replaced by the SIC ...

The ecology of woodland herbaceous species is reviewed. Many factors affect woodland herbs but there have been few studies of their impacts on long-term patterns. Results from a 10-year study of two species in a deciduous forest in Maryland are presented. Populations of Cynoglossum virginianum were influenced by their proximity to tree gap disturbances. Populations of Tipularia discolor were pr...

We envision situation-rooms and research laboratories in which all the walls are made from seamless ultra-high-resolution displays fed by data streamed over ultra-high-speed networks from distantly located visualization, storage servers, and high definition video cameras [1,6]. It will allow local and distributed groups of researchers to work together on large amounts of distributed heterogeneo...

BACKGROUND SAGE (serial analysis of gene expression) is a powerful method of analyzing gene expression for the entire transcriptome. There are currently many well-developed SAGE tools. However, the cross-comparison of different tissues is seldom addressed, thus limiting the identification of common- and tissue-specific tumor markers. METHODOLOGY/PRINCIPAL FINDINGS To improve the SAGE mining m...

Since the introduction of serial analysis of gene expression (SAGE) as a method to quantitatively analyze the differential expression of genes, several statistical tests have been published for the pairwise comparison of SAGE libraries. Testing the difference between the number of specific tags found in two SAGE libraries is hampered by the fact that each SAGE library is only one measurement: t...

he Solvent Alternatives GuidE, better known as SAGE, has T been a joint development effort between the Research Triangle Institute and the U.S. Environmental Protection Agency since the guide’s inception in 1992. The SAGE software tool was first released in 1993 and became an immediate success for the identification and selection of alternative nonand low-polluting surface cleaning options. The...

Biography: Sage Weil received his Ph.D. from UCSC in 2006 under the direction of Scott Brandt and Carlos Maltzahn. Sage designed Ceph as part of his PhD research. Since graduating, he has continued to refine the system with the goal of providing a stable next generation distributed file system. Prior to his graduate work, Sage helped found New Dream Network, the company behind Dreamhost web hos...
