A Hot Cusp-Shaped Confined Solar Flare
Aaron Hernandez-Perez, Yang Su, Julia K. Thalmann +5
We analyze a confined flare that developed a hot cusp-like structure high in the corona (H ~ 66 Mm). A growing cusp-shaped flare arcade is a typical feature in the standard model o…
Clean group rings over localizations of rings of integers
Yuanlin Li, Qinghai Zhong
A ring is said to be clean if each element of can be written as the sum of a unit and an idempotent. In a recent article (J. Algebra, 405 (2014), 168-178), Immormino and Mc…
Versatile stabilized finite element formulations for nearly and fully incompressible solid mechanics
Elias Karabelas, Gundolf Haase, Gernot Plank +1
Computational formulations for large strain, polyconvex, nearly incompressible elasticity have been extensively studied, but research on enhancing solution schemes that offer bette…
Pre-eruption processes: heating, particle acceleration and the formation of a hot channel before the 2012 October 20 M9.0 limb flare
Aaron Hernandez-Perez, Yang Su, Astrid M. Veronig +3
We report a detailed study of the pre-eruption activities that led to the occurrence of an M9.0 flare/CME event on 2012 October 20 in NOAA AR 11598. This includes the study of the…
The quenched SU(2) scalar-gluon vertex in minimal Landau gauge
Axel Maas
The question of whether confining effects are visible in correlation functions is a long-standing one. Complementing investigations on the propagators of fundamental and adjoint sc…
Scheme dependence of asymptotically free solutions
Holger Gies, René Sondenheimer, Alessandro Ugolotti +1
Recent studies have provided evidence for the existence of new asymptotically free trajectories in non-Abelian particle models without asymptotic symmetry in the high-energy limit.…
