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.

Software for Evaluating Convolutional Generative Adversarial Networks with Classical Random Process Noise Models
Data provided by National Institute of Standards and Technology
This research software package contains Python code to execute experiments on deep generative modeling of classical random process models for noise time series. Specifically, it includes Pytorch implementations of two generative adversarial network (GAN) models for time series based on convolutational neural networks (CNNs): WaveGAN, a 1-D CNN model, and STFT-GAN, a 2-D CNN model. In addition, there are methods for generating and evaluating noise time series defined several by classical random process models.

Effects of Non-Sinusoidal Current Phase Relationships on Single Flux Quantum Circuits
Data provided by National Institute of Standards and Technology
Data is for "Effects of Non-Sinusoidal Current Phase Relationships on Single Flux Quantum Circuits" and publication in IEEE Transactions on Applied Superconductivity. Data is from WRspice simulations, as well as MALT margin analysis. Further data analysis was done in python. One set of data is the pulse propagation delay of a chain of JTL's with different current phase relationships. The other set of data is the operating margins of T flip-flop circuits that have been optimized for different current-phase relationships.

Macroscale Compression at Different Temperatures and Orientations (CHAL-AMB2022-04-MaCTO)
Data provided by National Institute of Standards and Technology
This challenge is to predict the macroscopic stress-strain response of compression samples across a range of temperatures taken from the base leg of the IN625 AMB2018-01 build in both the build direction (Z-axis) and a transverse-build direction (Y-axis). The specific temperatures of interest are 298 K, 523 K, and 773 K. The calibration data provided in this dataset corresponds to the build direction compression tests done at 298 K and 773 K.
