We simulate the effect of gimbal-alignment errors and rotational step-size errors on measurements of the sensitivity matrix and intrinsic properties of a triaxial accelerometer. We restrict the study to measurements carried out on a two-axis accelerometer
We present a combined experimental and theoretical study of the transient absorption spectroscopy of N2O at the N K edge (400 eV) by employing an attosecond soft x-ray pulse and an overlapping intense femtosecond infrared pulse. Our experiment demonstrates

Recent advances in optical atomic clocks and optical time transfer have enabled new possibilities in precision metrology for both tests of fundamental physics and timing applications. Space offers both the potential to vary significantly the gravitational

Recent advances in optical atomic clocks and optical time transfer have enabled new possibilities in precision metrology for both tests of fundamental physics and timing applications. Here we describe a space mission concept that would place a state-of-the

For decades, physicists have used neutrinos from nuclear reactors to advance basic science. These pursuits have inspired many ideas for application of neutrino detectors in nuclear energy and security. While developments in neutrino detectors are now

There is considerable need for robust, accessible, and non-destructive Fe redox analysis methods for silicate-based minerals and glasses. A popular method assigns the distribution of Fe2+ and Fe3+ atoms using pre-edge features in the Fe K-edge X-ray
We present a study of noncritical phasematching behavior in thin-film, periodically poled lithium niobate (PPLN) waveguides. Noncritical phasematching refers to designing waveguides so that the phasematching is insensitive to variations in waveguide
The Precision Reactor Oscillation and Spectrum Experiment, PROSPECT, is designed to both perform a reactor-model independent search for eV-scale sterile neutrino oscillations at meter-long baselines and to make a precise measurement of the antineutrino
Superconducting electronic circuits have much to o er with regard to neuromorphic hardware. Superconducting quantum interference devices (SQUIDs) can serve as an active element to perform the thresholding operation of a neuron's soma. However, a SQUID has

External luminescence quantum yields of subcells within several multijunction solar cells were measured using a calibrated hyperspectral imaging system in electroluminescence mode. The measurements allowed direct comparison of subcell device parameters
