A Unified Dark Matter Model in sUED

We propose a dark matter model with standard model singlet extension of the universal extra dimension model (sUED) to explain the recent observations of ATIC, PPB-BETS, PAMELA and DAMA. Other than the standard model fields propagating in the bulk of a 5-dimensional space, one fermion field and one scalar field are introduced and both are standard model singlets. The zero mode of the new fermion...

Using Fraud Patterns for Fraud Risk Assessment of E-services

Every year, e-service providers report losses of billions of dollars due to fraud. Despite their huge efforts in implementing sophisticated fraud detection systems on top of their e-services, fraud effects seem to be rather increasing than decreasing. As a result, fraud risk assessment has been introduced as a fundamental part of e-service providers’ prevention strategies. In particular, identi...

Gene filtering by PCA for Affymetrix GeneChips

Due to the nature of the array experiments which examine the expression of tens of thousands of genes (or probesets) simultaneously, the number of null hypotheses to be tested is large. Hence multiple testing correction is often necessary to control the number of false positives. However, multiple testing correction can lead to low statistical power in detecting genes that are truly differentia...
