This video content contains flow visualization footage of the plume dynamics generated during the discharge of a Springfield 9mm handgun. The gun range is a modified 12 m (40 ft) sea cargo container specifically designed for handheld firearms research and includes an advanced air filtration system that can be turned on or off. The air filtration system is off during these experiments. In each video, a laser light-sheet is positioned either horizontally or vertically and bisects the barrel of the firearm.

Conventional molecular dynamics (MD) simulations using the GPU-enabled CUDA version of the pmemd executable (pmemd.cuda) in AMBER were applied to explore the structure and dymanics of MAPK, ERK2. The role of dual phosphorylation was explored by comparing 0P-ERK2 with 2P-ERK2 (two phosphate groups added at T183 and Y185). Both 0P-ERK2 and 2P-ERK2 models were treated with the ff19SB forcefield immersed in a solution of 0.15 M NaCl in OPC water. The results showed that the A-loop can adopt multiple long-lived (>5 microseconds) conformational states.

This data set corresponds to the results presented in the paper entitled "System-Level Evaluation of 5G NR UE-Based Relays", to appear in the proceeding of the 2023 IEEE Military Communications Conference.

This repository provides the raw data, analysis code, and results generated during a systematic evaluation of the impact of selected experimental protocol choices on the metagenomic sequencing analysis of microbiome samples. Briefly, a full factorial experimental design was implemented varying biological sample (n=5), operator (n=2), lot (n=2), extraction kit (n=2), 16S variable region (n=2), and reference database (n=3), and the main effects were calculated and compared between parameters (bias effects) and samples (real biological differences).

This dataset contains raw mechanical data (strain, stress and strain rate curvesand initial temperatures) for compression experiments performed on aluminum alloy 6061-T6using the NIST pulse-heated Kolsky Bar at strain rates between 2400 1/s and 2700 1/s and initialtemperatures from 23 °C to 527 °C and heating times ranging between 0.2 s and 3.5 s. At this time,the thermal history of the specimen during heating is not included in the dataset but this informationmay be included in a future update.

Data for "Nanosecond time-resolved dual-comb absorption spectroscopy." Each file contains the data behind the figure in its title.

Data from peer-reviewed publication: G.-W. Truong et al., Mid-infrared supermirrors with finesse exceeding 400 000, Nature Communications. For trace gas sensing and precision spectroscopy, optical cavities incorporating low-loss mirrors are indispensable for path length and optical intensity enhancement. Optical interference coatings in the visible and near-infrared (NIR) spectral regions have achieved total optical losses below 2 parts per million (ppm), enabling a cavity finesse in excess of 1 million.

This dataset contains CSV files for the figures in the paper titled "Multi-frequency Antenna Metrology with Sparse Measurements", to be submitted to IEEE Transactions on Antennas and Propagation or IEEE Transactions on Signal Processing. In this paper, we derive and experiment with approaches to use compressive sensing for multifrequency antenna radiation pattern measurements when samples are taken on a spherical domain. In particular, we develop sparsity and low-rank compressive sensing approaches and compare them for a simulated horn antenna.

This data repository provides a central location for a body of work using one build of nickel-based alloy 718 (IN718) material and resulted in three different studies. The IN718 parts were manufactured by laser powder bed fusion using a range of laser energy densities (manipulation of processing variables) and orientations with respect to the build direction. The influence of processing variables on resulting grain structures, pore structures, and mechanical properties were studied in the as-built (not heat treated) condition.
