As quantum key distribution (QKD) technology continues to mature, effectively achieving secure communication in optical networks still faces significant challenges. Recently, a research team from the ...

Researchers at Yale say they used Google to help unravel the complex structure and regulation of enzymes. In a new study, “Eigenvector centrality for characterization of protein allosteric pathways,” ...

SIAM Journal on Applied Mathematics, Vol. 78, No. 2 (2018), pp. 853-876 (24 pages) Eigenvector-based centrality measures are among the most popular centrality measures in network science. The ...

This paper examines the interconnectedness of stress-tested banks using financial news coverage. We investigate the behavior of bank networks during periods of stress. We then propose a new measure of ...

Abstract Let A be an n × n Hermitian matrix and A = UΛUH be its spectral decomposition, where U is a unitary matrix of order n and Λ is a diagonal matrix. In this note we present the perturbation ...
