Solar flares and Kelvin-Helmholtz instabilities: A parameter survey
Wenzhi Ruan, Chun Xia, Rony Keppens
Hard X-ray (HXR) sources are frequently observed near the top of solar flare loops, and the emission is widely ascribed to bremsstrahlung. We here revisit an alternative scenario w…

A geometric integration approach to smooth optimisation: Foundations of the discrete gradient method
Matthias J. Ehrhardt, Erlend S. Riis, Torbjørn Ringholm +1
Discrete gradient methods are geometric integration techniques that can preserve the dissipative structure of gradient flows. Due to the monotonic decay of the function values, the…
