Gravitation is the most tangible interaction of the four fundamental interactions of nature,
having been investigated long before the discovery of the electromagnetic, weak, and strong …

Data analysis is central to understanding phenomena in host–guest chemistry. We describe
here recent developments in this field starting with the revelation that the popular Job plot …

There were three independent measurement systems using three different Pitot probes on
the aircraft. In principle, this redundancy might have enabled a top-down uncertainty …

The “purity” of an organic compound typically refers, in practice, to an assignment of the
mass fraction content of the primary organic component present in the material. The “purity” …

Interlaboratory studies in measurement science, including key comparisons, and meta-
analyses in several fields, including medicine, serve to intercompare measurement results …

Abstract Development of reliable cell-based nanotoxicology assays is important for
evaluation of potentially hazardous engineered nanomaterials. Challenges to producing a …

(1) Measurand & Measurement Model. Define the measurand (property intended to be
measured, § 2), and formulate the measurement model (§ 4) that relates the value of the …

Judging the significance and reproducibility of quantitative research requires a good
understanding of relevant uncertainties, but it is often unclear how well these have been …

Environmental context Arsenic can be found in all environmental compartments in a large
number of chemical forms of varying toxicity. We performed an inter-laboratory comparison …

The Newtonian constant of gravitation, G, stands out in the landscape of the most common
fundamental constants owing to its surprisingly large relative uncertainty, which is …
