reductus: a stateless Python data reduction service with a browser front end

Abstract

The online data reduction service reductus transforms measurements in experimental science from laboratory coordinates into physically meaningful quantities with accurate estimation of uncertainties from instrumental settings and properties. This reduction process is based on a few well known transformations, but flexibility in the application of the transforms and algorithms supports flexibility in experiment design, enabling a broader range of measurements than a rigid reduction scheme for data. The user interface allows easy construction of arbitrary pipelines from well known data transforms using a visual data flow diagram. Source data are drawn from a networked, open data repository. The Python back end uses intelligent caching to store intermediate results of calculations for a highly responsive user experience. The reference implementation allows immediate reduction of measurements as they are recorded for the three neutron reflectometry instruments at the NIST Center for Neutron Research, without the need for visiting scientists to install additional software on their own computers.

Manipulation of Coupling and Magnon Transport in Magnetic Metal-Insulator Hybrid Structures

“…The fact that the magnonic spin valve operates efficiently at room temperature and it can be integrated with other Si-based electronics suggests that this material system can provide a nice platform for realizing magnon-based spin logic and memory devices. Additional references cited within the Supplemental Material are included here [33][34][35].…”

Layering of magnetic nanoparticles at amorphous magnetic templates with perpendicular anisotropy

“…The beam footprint on the sample was fixed at 25 mm. The raw data have been reduced by the Python package reductus 69 and corrected for beam footprint and background. No features were observed in the spin flip cross-sections and the non-spin flip channels were found to be identical.…”

On the interaction of softwood hemicellulose with cellulose surfaces in relation to molecular structure and physicochemical properties of hemicellulose

“…The raw data was reduced with the online data reduction service reductus. 56 The reduced data was evaluated with the Motofit software, which uses the Abeles matrix method to calculate the reflectivity from a stratified interfaces. 57,58 The best fit was obtained applying 4 layers as follows: Si-SiO 2 , hydrophobic layer, the transition layer containing acetyl groups of GGM interconnected with the hydrophobic layer and the top layer mainly consisting of the GGM sugar units.…”
