Violation of Leggett–Garg inequalities in quantum measurements with variable resolution and back-action

open access: yesNew Journal of Physics, 2012
Quantum mechanics violates Leggett–Garg inequalities because the operator formalism predicts correlations between different spin components that would correspond to negative joint probabilities for the outcomes of joint measurements.

On revision of the Guide to the Expression of Uncertainty in Measurement: Proofs of fundamental errors in Bayesian approaches

open access: yesMeasurement: Sensors, 2022
The process of revising the Guide to the Expression of Uncertainty in Measurement (GUM) is ongoing. A successful revision must be theoretically sound, so it must be based on a recognized paradigm for scientific data analysis.

Design of a new Z-test for the uncertainty of Covid-19 events under Neutrosophic statistics

open access: yesBMC Medical Research Methodology, 2022
Background The existing Z-test for uncertainty events does not give information about the measure of indeterminacy/uncertainty associated with the test. Methods This paper introduces the Z-test for uncertainty events under neutrosophic statistics.

Modified entropies as the origin of generalized uncertainty principles

open access: yesPhysics Letters B, 2023
The Heisenberg uncertainty principle is known to be connected to the entropic uncertainty principle. This correspondence is obtained employing a Gaussian probability distribution for wave functions associated to the Shannon entropy. Independently, due to

Confidence intervals and other statistical intervals in metrology [PDF]

open access: yesInternational Journal of Metrology and Quality Engineering, 2012
Typically, a measurement is regarded as being incomplete without a statement of uncertainty being provided with the result. Usually, the corresponding interval of measurement uncertainty will be an evaluated confidence interval, assuming that the ...
