Radiation can affect the correct behavior of an electronic device. Hence, microprocessors used for space missions need to be protected against fault. TMR (Triple modular redundancy) is mitigating various kinds faults in circuit. Although provides excellent level reliability, it takes a large area and suffers from high power consumption. To reduce overheads DMR (double used. The approach signifi...

We extend a previous bispectrum analysis of the COBE-DMR 4 year maps, allowing for the presence of correlations between all possible angular scales. We find that the non-Gaussian signal found earlier for bispectrum components including adjacent modes does not extend to triplets of modes with larger separations. Indeed for all separations ∆l > 1 we find that the COBE-DMR data is very Gaussian. T...

Although fully generative models have been successfully used to model the contents of text documents, they are often awkward to apply to combinations of text data and document metadata. In this paper we propose a Dirichlet-multinomial regression (DMR) topic model that includes a log-linear prior on document-topic distributions that is a function of observed features of the document, such as aut...

Live cell optical sensing employs label-free optical biosensors to non-invasively measure stimulus-induced dynamic mass redistribution (DMR) in live cells within the sensing volume of the biosensor. The resultant DMR signal is an integrated cellular response, and reflects cell signaling mediated through the cellular target(s) with which the stimulus intervenes. This article describes the uses o...

The COBE satellite, and the DMR experiment in particular, was extraordinarily successful. However, the DMR results were announced more than 6 years ago, during which time a great deal more has been learned about anisotropies in the Cosmic Microwave Background (CMB). We assess the current state of knowledge, and discuss where we might be going. The CMB experiments currently being designed and bu...

We describe a label-free integrative pharmacology on-target (iPOT) method to assess the pharmacology of drugs at the β(2)-adrenergic receptor. This method combines dynamic mass redistribution (DMR) assays using an array of probe molecule-hijacked cells with similarity analysis. The whole cell DMR assays track cell system-based, ligand-directed, and kinetics-dependent biased activities of the dr...

Cut-sky orthogonal mode analyses of the COBE-DMR 53 and 90 GHz sky maps are used to determine the normalization of a variety of open cosmogonical models based on the cold dark matter scenario. To constrain the allowed cosmological-parameter range for these open cosmogonies, the predictions of the DMR-normalized models are compared to various observational measures of cosmography and large-scale...

The COBE-DMR 4-year maps displayed a strong non-Gaussian signal in the “interscale” components of the bispectrum: their observed values did not display the scatter expected from Gaussian maps. We re-examine this and other suggested non-Gaussian features in the light of WMAP. We find that they all disappear. Given that it was proved that COBE-DMR high noise levels and documented systematics coul...
