Computer models of intense, laser-driven ion acceleration require expensive particle-in-cell simulations that may struggle to capture all the multi-scale, multi-dimensional physics involved at reasonable costs. Explored is an approach to ameliorate t

We report recent single-shot spatiotemporal measurements of laser pulses, including pulse-front tilt (PFT) and spatial chirp, taken at the Compact Multipulse Terawatt laser at the Jupiter Laser Facility in Livermore, CA. STRIPED FISH, a device that m

Enhanced analysis of experimental x-ray spectra through deep learning

Autor: D. A. Mariscal, C. M. Krauland, B. Z. Djordjević, G. G. Scott, R. A. Simpson, E. S. Grace, K. Swanson, T. Ma

X-ray spectroscopic data from high-energy-density laser-produced plasmas has long required thorough, time-consuming analysis to extract meaningful source conditions. There are often confounding factors due to rapidly evolving states and finite spatia

Recruitment of Young Rooks, Corvus frugilegus, into Breeding Populations

Autor: I. J. Patterson, E. S. Grace

Publikováno v: The Journal of Animal Ecology. 53:559

SUMMARY (1) The proportion of juveniles in a rook population in North-east Scotland declined in late summer, increased temporarily in autumn and rose again in spring. (2) The use of individually wing-tagged birds showed that these seasonal changes we
