Fast response of electron-scale turbulence to auxiliary heating cessation in National Spherical Torus Experiment
Yang Ren,W. X. Wang,B.P. LeBlanc,W. Guttenfelder,S.M. Kaye,Stephane Ethier,E. Mazzucato,Kun-Chun Lee,Calvin Domier,R.E. Bell,David R. Smith,Howard Yuh +11 more
TL;DR: Ono et al. as discussed by the authors reported the first observation of the fast response of electron-scale turbulence to auxiliary heating cessation in National Spherical Torus eXperiment (NSTE).
Journal ArticleDOI
Advanced Processing of 3D Computational Microwave Polarimetry Using a Near-Field Frequency-Diverse Antenna
TL;DR: The polarization states of the non-planar vector sensing fields with three-dimensional (3D) Jones vectors are described and the polarization diversity with the polarization ellipses in 3D space is examined.

Implementation and Characterization of a Two-Dimensional Printed Circuit Dynamic Metasurface Aperture for Computational Microwave Imaging
Timothy Sleasman,Mohammadreza F. Imani,Aaron V. Diebold,Michael Boyarsky,Kenneth P. Trofatter,David R. Smith +5 more
TL;DR: In this article, the design, fabrication, and experimental characterization of a two-dimensional, dynamically tuned, metasurface aperture is presented, emphasizing its potential performance in computational imaging applications.
Journal ArticleDOI
Near-field multistatic radar reconstruction with stretched-phase Fourier accelerated multistatic imaging
TL;DR: Stretched-phase FAMI (SP-FAMI) allows imaging in the Fresnel region of the antennas so that targets may be very close to the array while retaining the computational benefits of Fourier reconstruction.
Journal ArticleDOI
Monitoring WLCG with lambda-architecture: a new scalable data store and analytics platform for monitoring at petabyte scale.
L. Magnoni,Uthayanath Suthakar,C Cordeiro,M Georgiou,Julia Andreeva,Akram Khan,David R. Smith +6 more
TL;DR: This paper presents a new scalable data store and analytics platform designed by the Support for Distributed Computing (SDC) group, at the CERN IT department, which uses a variety of technologies each one targeting specific aspects of big-scale distributed data-processing (commonly referred as lambda-architecture approach).
