Bayesian Analysis of Variance for Repeat S-Parameter Measurements

Data provided by  National Institute of Standards and Technology

We utilize Bayesian analysis of variance to estimate the effects of calibration and disconnect levels for repeated scattering-parameter measurements made with a vector network analyzer. Here, we describe the Bayesian estimation technique, including our random effects model, prior assumptions, Markov chain Monte Carlo simulations, and convergence diagnostics. Our data is structured hierarchically, such that measurements are nested within repeats, which are nested within disconnects, which are further nested within calibrations.

A CTF-Based Data Augmentation Method for the Segmentation of Lipid Nanoparticles in Cryo-EM

Data provided by  National Institute of Standards and Technology

Lipid nanoparticles (LNPs) were prepared as described (https://doi.org/10.1038/s42003-021-02441-2) using the lipids DLin-KC2-DMA, DSPC, cholesterol, and PEG-DMG2000 at mol ratios of 50:10:38.5:1.5. RNA was not included and LNPs were ejected into pH 4 and pH 7.4 buffer after microfluidic assembly. To prepare samples for imaging, 3 μL of LNP formulation was applied to holey carbon grids (Quantifoil, R3.5/1, 200 mesh copper).

Supporting data for "DNA polymerase characteristics influence noise levels in sequencing of short tandem repeats"

Data provided by  National Institute of Standards and Technology

Polymerase chain reaction (PCR) applications including sequencing rely on accurate thermostable DNA polymerases. Polymerization errors may hinder the detection of low-level DNA variants such as mutations in clinical samples or DNA from minor contributors in crime scene traces. Short Tandem Repeat (STR) markers are particularly affected by artefacts. Apart from the regular random base substitutions, the repeated structure of STRs makes them prone to formation of stutter products. However, the mechanisms leading to stutter formation have not yet been fully elucidated.

AM Bench 2025 Measurement Results Data: Optical Microscopy of arrays of adjacent laser tracks (pads) on alloy 718 plate

Data provided by  National Institute of Standards and Technology

The dataset is melt pool cross-sectional microscopy and measurements for 2D arrays of laser tracks on solid metal IN718 plates and single layers of IN718 powder on solid metal IN718 plates. The primary laser parameters such as laser power, speed, and spot diameter, and hatch spacing were fixed. The pad geometry, laser turnaround time (i.e., skywriting time), and powder layer thickness were the investigated variables. The experiments were part of AM Bench 2025 (AMB2025-06 and AMB2025-07 benchmarks).

Affinis: tools for inferring relations from co-occurrence data

Data provided by  National Institute of Standards and Technology

Affinis is a tool for assisting in unsupervised structure learning on sparse, binary data. For large (sparse) feature matrices, especially ones with binary-valued entries, techniques to figure out the underlying structure of the feature space are widely varied, and different communities have widely different practices and assumptions for what is an appropriate approach. Affinis provides reference implementations for many of these methods, with a consistent API to enable community adoption and a shared benchmarking environment.
