Abstract For the integrity monitoring of a multi-source PNT (Positioning, Navigation, and Timing) resilient fusion navigation system, a theoretical framework of multi-level autonomous integrity monitoring is proposed.According to the mode of multi-source fusion navigation, the framework adopts the top-down logic structure and establishes Green Sham
Following an initial Round Robin inter-comparison of gamma spectrometry measurements reported in 2014, this paper presents results from the first part of a second Round Robin inter-comparison commissioned by the European Working Group on Reactor Dosimetry in 2018.Measurements were performed by thirteen Pendants European organisations on a set of ir
We study how functional constraints bound and shape evolution through an analysis of mammalian voltage-gated sodium channels.The primary function of sodium channels is to allow the propagation of action potentials.Since Hodgkin and Huxley, mathematical models have suggested that sodium channel properties need to be tightly constrained for an action
