Inter- and intra-observer variation was examined among six microscopists who read 50 scrub typhus (ST) and murine typhus (MT) indirect immunofluorescence assay (IFA) immunoglobulin M (IgM) slides. Inter-observer agreement was moderate (κ = 0.45) for MT and fair (κ = 0.32) for ST, and was significantly correlated with experience (P = 0.03 and P = 0.004, respectively); κ-scores for intra-observer...

Node localization technology is a key technology of WSN, and this paper proposes a rank sequence localization algorithm based on Voronoi and Spearman. First of all, the paper divides the localization space of WSN according to the Voronoi diagram, takes the polygon’s points, center of gravity and the boundary intersection as virtual anchor nodes, and builds the rank sequence list for virtual anc...

Ventilation distribution calculation using 4D CT has shown promising potential in several clinical applications. This study evaluated the direct geometric ventilation calculation method, namely the ΔV method, with xenon-enhanced CT (XeCT) ventilation data from four sheep, and compared it with two other published meth-ods, the Jacobian and the Hounsfield unit (HU) methods. Spearman correlation c...
