-the coupled production and utilization of dissolved X organic matter (DOM) through the activities of phyto plankton production, predator)' consumption, and microheterotrophic growth define the "microbial loop," which constitutes an important pathway of carbon and energy' flow in all marine ecosystems (Azam et al. 1983). Comprehensive results from both the AMERIEZ (Antarctic Marine Ecosystem Re...

This is the first of two lectures by Phil Green on “Sequence Assembly.” Yeast and some of the bacterial genomes have already been completely sequenced. There is also a rapidly growing body of known human sequence. All this has been because of our ability to read DNA. This lecture discusses the shotgun strategy for rapid DNA sequencing, and begins discussion of sequence assembly algorithms (to b...

Weedy Amaranthus species frequently cause economically significant reductions in crop yields. Accurate identification of Amaranthus species is important for efficient weed control, but Amaranthus species can interbreed, which might cause difficulty when identifying hybrid-derived specimens. To determine which of several economically important weedy Amaranthus species are most genetically simila...

Palmer [1] has the advantage of being simple to implement and have good performances compared to the other similarity measures [2]. Nevertheless, the Wu and Palmer measure present the following disadvantage: in some situations, the similarity of two elements of an IS-A ontology contained in the neighborhood exceeds the similarity value of two elements contained in the same hierarchy. This situa...

Research, directly assessing sex-dependent differences in global versus local processing is sparse, but predominantly suggesting that men show a stronger global processing bias than women. Utilizing the Kimchi-Palmer task however, sex differences in the number of global choices can only be found in children, but not in adults. In the current study 52 men and 46 women completed a computerized ve...

Glyphosate-resistant Palmer amaranth is the most troublesome pest in Arkansas cotton production. The prolific seed production, high germination rate, and rapid growth coupled with the lack of post emergence herbicide control options make this species a constant threat to cotton farmers. Sustainable control of Palmer amaranth requires careful management of seed in the soil seedbank. To emphasize...

Palmer amaranth (Amaranthus palmeri) is known to be glyphosate-resistant and one of the most common and troublesome weeds in Arkansas cotton production. Glufosinate is known to provide good control of 1-4 inch Palmer amaranth, but control of larger weeds is erratic. The lack of control provided by glufosinate on large weeds may be caused by coverage issues. The objective of this study was to ev...
