Structural Analysis of Laplacian Spectral Properties of Large-Scale Networks
Victor M. Preciado, Ali Jadbabaie, George C. Verghese
Using methods from algebraic graph theory and convex optimization, we study the relationship between local structural features of a network and spectral properties of its Laplacian…
Operating Regimes of Signaling Cycles: Statics, Dynamics, and Noise Filtering
Carlos Gomez-Uribe, George C. Verghese, Leonid A. Mirny
A ubiquitous building block of signaling pathways is a cycle of covalent modification (e.g., phosphorylation and dephosphorylation in MAPK cascades). Our paper explores the kind of…
Optimal Detection of Symmetric Mixed Quantum States
Yonina C. Eldar, Alexandre Megretski, George C. Verghese
We develop a sufficient condition for the least-squares measurement (LSM), or the square-root measurement, to minimize the probability of a detection error when distinguishing betw…
Designing Optimal Quantum Detectors Via Semidefinite Programming
Yonina C. Eldar, Alexandre Megretski, George C. Verghese
We consider the problem of designing an optimal quantum detector to minimize the probability of a detection error when distinguishing between a collection of quantum states, repres…
