This paper evaluates the short-term and long-term performance of a new type of dc secondary voltage standard at 10 V by direct comparison to a programmable Josephson voltage standard. Allan deviation measurements indicated a noise floor of 4.5 nV, enabling potential new applications in voltage metrology and possibly reducing uncertainty along the dissemination chain from primary calibration laboratories to calibration laboratories.

This publication contains the data presented in the associated proceeding paper ”Pushing the Envelope in Mechanical Characterization of Copper in Hybrid-Bonding Patterns for Advanced Packaging: from Instrumented Indentation to Multimodal Atomic Force Microscopy” submitted for publication in the proceedings of the 2026 IEEE 76th Electronic Components and Technology Conference.
The datasets were obtained in single-step and multi-step indentations using instrumented indentation (IIT) and atomic force microscope (AFM) on hybrid-bonding copper at room temperature.

SpherIndent is a modular, open-source software package with graphical user interface (GUI) for analysis of quasi-static spherical indentation experiments conducted in single-step or multi-step loading sequences. All components are developed in Python programming language with the GUI built on Tkinter. The software package is essentially constructed using libraries including NumPy, Pandas, SciPy, Sklearn, Matplotlib, and OpenCV. Data storage, from raw to processed and analyzed data (including figures) is handled via Pickle with traceability, efficient retrieval and sharing in mind.

This paper evaluates the performance of a new type of 2 V traveling cryocooled Programmable Josephson Voltage Standard for performing on-site verification of quantum voltage standards. Direct comparison with a 10 V system showed agreement of 8 parts in 10^11 at 2 V. This result shows that, despite the lower voltage, the direct Josephson-to-Josephson system comparison method provides a two orders-of-magnitude improvement over traveling Zener standards for verifying Josephson voltage standards.

This dataset contains two-port S-parameter measurements (S2P format) acquired in a typical mode-stirred reverberation chamber. The measurements support training of artificial neural networks to infer optimal mechanical stirrer and turntable positions for realizing a target wireless channel response. Data provides dense sampling of scattering parameters across mechanical configurations for four fixed excitation antennas.

The ‘Import Monitor’ aggregates detailed license information and makes it available for public analysis on a weekly basis. All imported aluminum products under the U.S. Bureau of the Census (Census) definition of steel mill products are required to have an import license effective June 28, 2021. The data from the licensing system are used in conjunction with similar Census data to put together the ‘Import Monitor’. This Monitor helps alert users to changes in import patterns.

The NOAA Geostationary Operational Environmental Satellite (GOES) series of satellites goal is to monitor the atmosphere for severe weather development such as tornadoes, flash floods, hail storms and hurricanes. The positioning of the GOES satellites at around 36,000 km (22,000 statute miles) above the equator at a fixed position above the earth allowed them to scan large geographic regions of the Western Hemisphere and as frequently as once every half hour.

The Global Precipitation Climatology Project (GPCP) consists of monthly satellite-gauge and associated precipitation error estimates and covers the period January 1983 to the present. For GPCP V3 monthly precipitation, the primary outputs include combined satellite-gauge precipitation rate, combined satellite-gauge precipitation random error, multi-satellite precipitation, wind-loss adjusted gauge precipitation, and probability of liquid phase, among others. The product is archived on a 0.5-degree global grid.
