## A new calibration setup for lock-in amplifiers in the low frequency range and its validation in a bilateral comparison

This paper addresses the calibration of lock-in amplifiers in the low frequency range. A simple but effective calibration setup implemented at INRIM is described. This includes a stable low-voltage source, composed of a digital sine wave generator and a cascade of two voltage dividers, one inductive and one resistive. The magnitude error is the lock-in magnitude error, which can be determined with an uncertainty of the order of 10 −4 or better, that is, two orders of magnitude lower than the…

## Absolute frequency of 87 Sr at 1.8 × 10 −16 uncertainty by reference to remote primary frequency standards

The optical lattice clock NICT-Sr1 regularly reports calibration measurements of the international timescale TAI. By comparing measurement results to the reports of eight primary frequency standards, we find the absolute frequency of the 87 Sr clock transition to be ##IMG## [http://ej.iop.org/images/0026-1394/58/2/025006/metabc232ieqn1.gif] {$f \left(\mathrm{S}\mathrm{r}\right)=429\enspace 228\enspace 004\enspace 229\enspace 873.082\left(76\right)\enspace \mathrm{H}\mathrm{z}$} , with a fractional uncertainty of less than 1.8 × 10 −16 approaching the systematic limits of the best realization of the SI second. Our result is consistent with other recent measurements and…

## Strategic National Stockpile Ventilators Can Support ‘Most’ Patients, but That Is Not Enough

Critical care hasn’t had many breakthroughs in recent years and in order to change that, I believe we need to put more of an emphasis on integrating technology—specifically artificial intelligence (AI) —into the field.
