Through the analysis, we shed light on how modern hardware affects the implementation of data operators [...] Jens Teubner, Gustavo Alonso, and M. Tamer Öszu Published Proceedings of the 29th Int'l Conference on Data Engineering (ICDE), Brisbane, Australia, April 2013. Download paper (PDF) Abstract The architectural [...] can be omitted without sacrificing performance. In this paper we demonstrate through experimental analysis of different algorithms and architectures that hardware still matters. Join algorithms that are …

t of the ratio of branching fractions for Λb→ψ(2S)Λ and Λb→J/ψΛ decays is presented. This analysis uses a data set corresponding to 3 fb-1, collected by the LHCb experiment at a centre-of-mass energy of [...] 0.016 (syst) ± 0.011 (BR). The second analysis is a on-going measurement of CP violation in g in B0→J/ψKS, B0→ψ(2S)KS and Bs0→J/ψKS decays. The analysed LHCb data sets correspond to 6 fb-1, at a centre-of-mass …

basic approach. First, methods of enrichment analysis will also be applied to protein measurements and to SNP data as well as to combinations of different data sources (SNPs, gene expression, protein expression) [...] I3: Enrich Enrichment analyses for multiple data sources and complex statistical designs In many statistical analyses with high-dimensional omics data, statistically significant gene groups are identified [...] averages of gene groups identified from different sources then allow an integrative analysis of the different genomic data types. Second, statistical designs that are more complex than two-group comparisons …
