Stochastic ordering of medians in exchangeable trivariate normal vectors

In this paper, we establish the stochastic ordering of median from an exchangeable trivariate normal vector based on the strength of the correlation coefficient. Specifically, by considering two exchangeable trivariate normal vectors with different correlation coefficients, we show that the absolute value of the median in the vector with smaller correlation coefficient is stochastically smaller than the absolute value of the median in the vector with larger correlation coefficient. We prove this result by utilizing skew-normal distributions.     

A Photoreactive G‐Quadruplex Ligand Triggered by Green Light

A photoreactive molecular dye targeting the G‐quadruplex nucleic acid (G4) of the human telomeric sequence Tel22, and several mutated analogues, was activated by green light (λ=532 nm). Highly selective covalent modification of G4 versus single‐stranded and double‐stranded DNA was achieved with efficiency up to 64 %. The phenoxyl radical was generated and detected by laser‐flash photolysis as a reactive intermediate that targeted loop thymine residues. These insights may suggest a non‐invasive tool for selective nucleic acid tagging and “pull‐down” cellular applications.
