SI Traceable Solar Spectral Irradiance Measurement Based on a Quantum Benchmark: A Prototype Design
Remote Sensing, 2020 We propose a space benchmark sensor with onboard SI (Système International) traceability by means of quantum optical radiometry. Correlated photon pairs generated by spontaneous parametric down-conversion (SPDC) in nonlinear crystals are used to ...

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Causal isotonic calibration for heterogeneous treatment effects [PDF]
arXiv, 2023 We propose causal isotonic calibration, a novel nonparametric method for calibrating predictors of heterogeneous treatment effects. Furthermore, we introduce cross-calibration, a data-efficient variant of calibration that eliminates the need for hold-out calibration sets.

Precise calibration method for triaxial magnetometers not requiring Earth's field compensation [PDF]
IEEE Transactions on Instrumentation and Measurement, 64(5),
pp.1242-1247, 2015, 2019 A calibration procedure for calibrations of triaxial magnetometers is presented. The procedure uses a triaxial Helmholtz coil system and an Overhauser scalar magnetometer and is performed in the Earth's field range. The triaxial coils are first calibrated with the Overhauser magnetometer, and subsequently, a triaxial magnetometer calibration is ...

Calibration: the Achilles heel of predictive analytics
BMC Medicine, 2019 BackgroundThe assessment of calibration performance of risk prediction models based on regression or more flexible machine learning algorithms receives little attention.Main textHerein, we argue that this needs to change immediately because poorly ...

Towards dynamic camera calibration for constrained flexible mirror imaging [PDF]
, 2008 Flexible mirror imaging systems consisting of a perspective camera viewing a scene reflected in a flexible mirror can provide direct control over image field-of-view and resolution. However, calibration of such systems is difficult due to the vast range
