Serial analysis of gene expression (SAGE) experiments could provide us the expression level of thousands of genes in a biological sample. However, the number of available samples is relatively small. Such undersampled problem needs to be carefully analyzed from a machine learning perspective. In this paper, we combine several state-of-theart techniques for classification, feature selection, and...

Software systems typically contain large APIs that are informally specified and hence easily misused. This paper presents the Sage programming language, which is designed to enforce precise interface specifications in a flexible manner. The Sage type system uses a synthesis of the type Dynamic, first-class types, and arbitrary refinement types. Since type checking for this expressive language i...

Soil moisture is a key limiting resource in arid and semi-arid environments for woody shrub species. We assessed if three arid communities differed in their level of dry season soil moisture content and if the dominant species in these communities differed in their ability to use soil moisture. Water potential of all of the dominant woody plant species occurring in chaparral, coastal sage, and ...
