The molecular mechanisms by which central nervous system-specific genes are expressed only in the nervous system and repressed in other tissues remain a central issue in developmental and regulatory biology. Here, we report that the zinc-finger gene-specific repressor element RE-1 silencing transcription factor/neuronal restricted silencing factor(More)
Pairs of letters and numbers were shown to 11-, l4-, and l9-year-olds. One stimulus in a pair was presented upright. The second, which was either identical to the first or a mirror image of it, was rotated 0 to 150 " from the vertical. Individuals judged if the stimuli in a pair would be identical or mirror images if presented at the same orientation. They(More)
We collected and completely sequenced 32,127 full-length complementary DNA clones from Oryza sativa L. ssp. japonica cv. "Nipponbare." Mapping of these clones to genomic DNA revealed approximately 20,500 transcriptional units (TUs) in the rice genome. For each TU, we selected 60-mers using an algorithm that took into account some DNA conditions such as base(More)
BACKGROUND Until recently, few genomic reagents specific for non-human primate research have been available. To address this need, we have constructed a macaque-specific high-density oligonucleotide microarray by using highly fragmented low-pass sequence contigs from the rhesus genome project together with the detailed sequence and exon structure of the(More)
Avian erythroblastosis virus strain R (AEV)-transformed, cloned erythroleukemia cells from three different ages of SC strain chickens were analyzed before and after differentiation induced by 1.0 mM butyric acid for expression of chicken fetal antigens (CFAs) and chicken adult antigens (CAAs) and for hemoglobin expression. Immunofluorescent analyses show(More)

The first section of the paper discusses the recommendations of the National Academy of Sciences Panel with respect to geographic adjustment of poverty thresholds and the methodology used to implement these recommendations. Second, the paper discusses subsequent research that resulted in modifications to the panel's specific recommendations incorporated in(More)
This paper takes a complexity theory approach to looking at language learning, an approach that investigates how language learners adapt to and interact with people and their environment. Based on interviews with four graduate students, it shows how complexity theory can help us understand both the situatedness of language learning and also commonalities(More)
