Diffuse auroral precipitation driven by lower-band chorus second harmonics
Scattering by the upper- and lower-band chorus waves are the dominant cause of diffuse auroral precipitation. Here, we show that the lower-band chorus alone satisfies the preferred condition for the generation of second harmonics to trigger the diffuse auroral electron precipitation.
Parallel computers are fundamentally more energy efficient than serial computers
Energy consumption and in turn heat dissipation is a core obstacle in the quest of engineering ever more faster computers. We show massive parallelization of computing hardware and software offers a way to further increase energy efficiency of computers by orders of magnitude.
Laplacian Renormalization group for heterogeneous networks
Complex networks have been introduced as the best theoretical framework to model a large variety of physical, biological, and social systems where an intertwined pattern of interactions couples many elements.
A general framework for quantifying uncertainty at scale
Quantifying uncertainty and performing sensitivity analysis in real-world, large-scale numerical simulations is virtually impossible with standard methods. We show that our recently developed sensitivity-driven sparse grid interpolation methods enables these two important tasks at scale.
The landscape of the quantum start-up ecosystem
Quantum technologies (QT) have been rapidly emerging in the last several years and becoming a topic of interest for commercial actors. In this paper, we present a landscaping study with a gathered dataset of 441 companies from 42 countries that we identify as quantum start-ups.
