Activation loop plasticity and active site coupling in the MAP kinase, ERK2: Supplementary Data, Trajectories, and Scripts

Data provided by  National Institute of Standards and Technology

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.

Flow visualization of gunshot residue plumes from handguns.

Data provided by  National Institute of Standards and Technology

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.

Data to support "Implementation of SPME and Rapid GC-MS as a Screening Approach for Forensic Fire Debris Applications"

Data provided by  National Institute of Standards and Technology

This data set contains raw data files for ignitable liquids, mock fire debris samples, and other related samples. All samples were extracted using solid phase microextraction (SPME) and analyzed by rapid gas chromatography-mass spectrometry (GC-MS), a recently developed chromatographic screening technique. Data is included for instrument inlet optimization, analysis of neat ignitable liquids (gasoline and diesel fuel), and analysis of mock burn samples consisting of carpet and wood substrates spiked with either ignitable liquid.

Data associated with "Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment"

Data provided by  National Institute of Standards and Technology

Data associated with the publication: "Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment"Applying a magnetic field as a method for tuning the frequency of Autler-Townes splitting for Rydberg electrometry has recently been demonstrated. In the corresponding paper, we provide a theoretical understanding of EIT signals in the presence of a large magnetic field, as well as demonstrate some advantages of this technique over traditional Autler-Townes based electrometry.

Smart network repository based on Neo4j native graph database

Data provided by  National Institute of Standards and Technology

To address the increasing complexity of network management and the limitations of data repositories in handling the various network operational data, this paper proposes a novel repository design that uniformly represents network operational data while allowing for a multiple abstractions access to the information. This smart repository simplifies network management functions by enabling network verification directly within the repository.

Data associated with "Characterizing the broadband RF permittivity of 3D-integrated layers in a glass wafer stack from 100 MHz to 30 GHz" for the 2024 International Microwave Symposium (IMS) in Washington, D.C.

Data provided by  National Institute of Standards and Technology

We present a method for accurately determining the permittivity of dielectric materials in 3D integrated structures at broadband RF frequencies. With applications of microwave and millimeter-wave electronics on the rise, reliable methods for measuring the electrical properties of dielectrics used in integrated circuits are critical. We outline an on-wafer method for extracting the permittivity of a 3D multilayer glass structure from 100 MHz to 30 GHz using S-parameter measurements of different calibration chips.
