Dataset presenting improved bandwidth in Rydberg atom electrometry with an optical frequency comb probe

Data provided by  National Institute of Standards and Technology

Rydberg atom-based receivers of modulated radio frequency (RF) fields are promising systems for measurements. These systems are self-calibrating, widely tunable, nearly transparent to RF fields, and can be electrically small. However, the instantaneous bandwidth of current Rydberg atom receivers is typically less than 1 MHz.

Measuring VHF Detector Linearity using a Quantum-Based Source, CPEM 2024

Data provided by  National Institute of Standards and Technology

Data sets for measuring VHF detector linearity using a Josephson Arbitrary Waveform Synthesizer (JAWS). Two instruments are measured: an RF power sensor and a fast ADC. The VHF-JAWS source consists of a chip with 12,810~Josephson junctions located in a cryocooler and driven to produce quantum-based ac waveforms at frequencies up to 50.05~MHz and power up to -19~dBm. We first confirm that the device is operating correctly by measuring the dc offset quantum-locking range (Fig. 2) and then measure the system output power with an RF power sensor (Fig.

Dataset for Establishing a Reference Focal Plane Using Machine Learning and Beads for Brightfield Imaging

Data provided by  National Institute of Standards and Technology

This dataset consists of sets of images corresponding to the data sets 1-8 described in Table 1 in the manuscript "Establishing a Reference Focal Plane Using Machine Learning and Beads for Brightfield Imaging".
Data sets from A2K contain two .zip folders: one with the .tiff images and one with the corresponding .txt file with live and dead cell concentration enumeration.

Code to accompany "Superancillary Equations for the Multiparameter Equations of State in REFPROP 10.0"

Data provided by  National Institute of Standards and Technology

This record includes the C++ files used to generate superancillary equations (sets of Chebyshev expansions for the co-existing thermodynamic data) for the multiparameter EOS included in NIST REFPROP 10.0. The calculations in C++ are done in extended precision and the Chebyshev expansions are stored in double precision. The python scripts are used to post-process the generated sets of Chebyshev expansions.

3D shape and size data for 10084 and 14163 lunar regolith particles

Data provided by  National Institute of Standards and Technology

This database contains 3D shape and size data for 10084 (Apollo 11) and 14163 (Apollo 14) real lunar regolith particles, along with STL files for the approximately 14,000 particles studied via X-ray micro-CT and X-ray nano-CT. The database also contains similar information for the lunar regolith simulant JSC-1A but for over 100,000 particles. There are also images for all 10084 and 14163 particles examined by SEM, which are different particles out of the same material.

Code for qDIC-based Strain Localization Analysis with Wavelets (Q-SLAW)

Data provided by  National Institute of Standards and Technology

This dataset is an archival version of an algorithm implementation for strain localization analysis in digital image correlation data. The original application is to detect the occurrence of localization (i.e., collective buckling, hotspots, etc.) in uniaxial stress testing of polymer foams instrumented with 2D digital image correlation. The full-field strain maps are processed with a Marr wavelet and regions of excess strain are identified.
