BACKGROUND Sequence and transcriptional variability within and between individuals are typically studied independently. The joint analysis of sequence and gene expression variation (genetical genomics) provides insight into the role of linked sequence variation in the regulation of gene expression. We investigated the role of sequence variation in cis on(More)
With the advent of technologies that allow simultaneous genotyping of thousands of single-nucleotide polymorphisms (SNPs) across the genome, the genetic contributions to complex diseases can be explored at an unprecedented detail. This study is among the first to apply the genome-wide association study (GWAS) approach to Alzheimer disease (AD). We present(More)
Advances in high-throughput genotyping and the International HapMap Project have enabled association studies at the whole-genome level. We have constructed whole-genome genotyping panels of over 550,000 (HumanHap550) and 650,000 (HumanHap650Y) SNP loci by choosing tag SNPs from all populations genotyped by the International HapMap Project. These panels also(More)

A variety of tasks conducted by aviation system decision makers and researchers requires analyzing aircraft trajectory data. Datasets containing high frequency aircraft position information collected over large geographic areas and long periods of time are too large to store in the primary memory of personal computers. This paper introduces the use of(More)
Governments are increasingly making public transportation data available to the public on the Internet. The data can be used to explore and characterize current and historical service levels or to forecast operations in the immediate future. This paper considers, as an example, real-time bus location data provided by the San Francisco Municipal Transit(More)
