Calculating Observables in Inhomogeneous Cosmologies I: General Framework

open access: yes, 2017
We lay out a general framework for calculating the variation of a set of cosmological observables, down the past null cone of an arbitrarily placed observer, in a given arbitrary inhomogeneous metric.

The potential impact of CT-MRI matching on tumor volume delineation in advanced head and neck cancer [PDF]

open access: yes, 1997
To study the potential impact of the combined use of CT and MRI scans on the Gross Tumor Volume (GTV) estimation and interobserver variation. Four observers outlined the GTV in six patients with advanced head and neck cancer on CT, axial MRI, and coronal

Observer variation and quality control of cytodiagnosis [PDF]

open access: yesJournal of Clinical Pathology, 1974
The aim of quality control of a laboratory investigation is to ensure that similar results are obtained on the same material at different centres. To investigate its practicability in cytodiagnosis, the same cytological material was examined independently at six centres.
