In this paper, we describe new protocols augmenting traditional cache coherency mechanisms to implement fault-tolerance based on Recovery Blocks and checkpointing. Concurrent processes compound rollback recovery since the rollback can potentially lead to a "domino-effect" whereby the process is rolled back to the beginning. Several approaches have been proposed to limit the domino effect. One s...

This paper considers the effects of gravitational induced uncertainty on some well-known quantum optics issues. First we will show that gravitational effects at quantum level destroy the notion of harmonic oscillations. Then it will be shown that, although it is possible(at least in principle) to have complete coherency and vanishing broadening in usual quantum optics, gravitational induced unc...

In this paper we investigate coherence sets in polarimetric SAR interferometry. The coherence set is closely related to the numerical range (field of values). This paper aims to bring the numerical range to the attention of the radar research community. The mathematical understanding of the numerical range helps to understand theoretical and physical properties of coherence and coherency matrix...

We propose an approach for quantifying the biological relatedness between gene products, based on their properties, and measure their similarities using exclusively statistical NLP techniques and Gene Ontology (GO) annotations. We also present a novel similarity figure of merit, based on the vector space model, which assesses gene expression analysis results and scores gene product clusters' bi...

Based on the sources’ smoothed rank profile (SRP) and modified minimum description length (MMDL) principle, a method for estimation of the source coherency structure (SCS) and the number of wideband sources is proposed in this paper. Instead of focusing, we first use a spatial smoothing technique to pre-process the array covariance matrix of each frequency for de-correlating the sources and the...
