RGTM 10169

Data provided by  National Institute of Standards and Technology

NIST developed a reference material consisting of synthetic fragments of the SARS-CoV-2 virus RNA, which is the target of molecular diagnostic tests. These RNA fragments can assist in the development and validation of RT-qPCR assays for the detection SARS-CoV-2. The RNA fragments are characterized for concentration using digital PCR methods, may be used to assess limits of detection for SARS-CoV-2 assays, and may calibrate other in-house or commercial SARS-CoV-2 controls. This dataset includes data used for RTGM 10169 SARs-Cov-2 Research Grade Test Material validation.

Modeling Line Broadening and Distortion Due to Inhomogeneous Fields for Rydberg Electrometry

Data provided by  National Institute of Standards and Technology

This set corresponds to a (pending) publication, where we attempt to model spectral features appearing in the lab by calculating many segments of an inhomogeneous field. Every data set here is a transmission value, either normalized to 1 in modeled data, or an arbitrary-scaled voltage reading from a photodiode onto an oscilloscope. These are given in scans over coupling photon detuning, delta_C, which is divided by 2 pi, and given in MHz. Arrays are scans over delta_C, and position/fieldstrength, for figure 3.

Rydberg state engineering: A comparison of tuning schemes for continuous frequency sensing

Data provided by  National Institute of Standards and Technology

On-resonance Rydberg atom-based radio-frequency (RF) electric field sensing methods remain limited by the narrow frequency signal detection bands available by resonant transitions. The use ofan additional RF tuner field to dress or shift a target Rydberg state can be used to return a detuned signal field to resonance and thus dramatically extend the frequency range available for resonantsensing.

MAM Consortium Interlaboratory Study Raw Data

Data provided by  National Institute of Standards and Technology

These LC-MS and LC-MS/MS raw data were collected for purposes of an interlaboratory study evaluating the multi-attribute method (MAM). Tryptic digests of native NISTmAb (the "Reference" and the "Unknown" samples), degraded NISTmAb (the "pH Stress" sample) and NISTmAb spiked with 15 heavy-labeled synthetic peptides (the "Spike" sample) were sent to each participating laboratory. One injection of each digest was acquired in MS-only mode, while a second injection was acquired in MS/MS mode.

Datasets from an interlaboratory comparison to characterize a multi-modal polydisperse sub-micrometer bead dispersion

Data provided by  National Institute of Standards and Technology

These four data files contain datasets from an interlaboratory comparison that characterized a polydisperse five-population bead dispersion in water. A more detailed version of this description is available in the ReadMe file (PdP-ILC_datasets_ReadMe_v1.txt), which also includes definitions of abbreviations used in the data files. Paired samples were evaluated, so the datasets are organized as pairs associated with a randomly assigned laboratory number.

NIST-LANL Lanthanide/Actinide Opacity Database

Data provided by  National Institute of Standards and Technology

The database contains radiative line-binned opacities for lanthanides (atomic number 57<=Z<=70) and actinides (atomic number 89<=Z<=102) which are of paramount importance for simulation of light curves and spectra produced by kilonovae. The opacities were calculated by the LANL group under the assumption of local thermodynamic equilibrium. The temperature grid cover the range from 0.01 eV to 5.0 eV while the mass density grid covers 16 orders of magnitude. The database provide search and selection tools along with graphical and tabular outputs.
