A Method to Construct Early-Warning and Emergency Response System for Sulfur Hexafluoride Leakage in Substations

open access: yesIEEE Access, 2020
Sulfur hexafluoride (SF6) gas leakage in populous urban areas, once occurring, can cause death from suffocation if its concentration largely exceeds 1000ppm and oxygen concentration is low than 19 vol-%.

Leakage-Resilient Storage [PDF]

open access: yes, 2010
We study a problem of secure data storage on hardware that may leak information. We introduce a new primitive, that we call leakage-resilient storage (LRS), which is an (unkeyed) scheme for encoding messages, and can be viewed as a generalization of the All-Or-Nothing Transform (AONT, Rivest 1997).

Coarse-Grained Effective Hamiltonian via the Magnus Expansion for a Three-Level System

open access: yesEntropy, 2023
Quantum state processing is one of the main tools of quantum technologies. While real systems are complicated and/or may be driven by non-ideal control, they may nevertheless exhibit simple dynamics approximately confined to a low-energy Hilbert subspace.
