Abstract: Cluster analysis of gene expression data is a popular and successful way of elucidating underlying biological processes. Typically, cluster analysis methods seek to group genes that are differentially expressed across experimental conditions. However, real biological… read more here.

Abstract: Let $\mathcal{E}$ and $\mathcal{F}$ be symmetrically $\Delta$-normed (in particular, quasi-normed) operator spaces affiliated with semifinite von Neumann algebras $\mathcal{M}_1$ and $\mathcal{M}_2$, respectively. We establish a noncommutative version of Abramovich's theorem \cite{A1983}, which provides the general… read more here.

DOI: 10.1080/10236198.2016.1195828
Abstract: Encryption is a well established technology to sensitive data. However, once encrypted, data can no longer be easily range queried or indexed efficiently. Order-preserving symmetric encryption (OPE) helps with this problem whose encryption function preserves… read more here.
