Firehose instabilities triggered by the solar wind suprathermal electrons
S. M. Shaaban, M. Lazar, R. A. Lopez +2
In collision-poor plasmas from space, e.g., solar wind, terrestrial magnetospheres, kinetic instabilities are expected to play a major role in constraining the temperature anisotro…
Solution Refinement at Regular Points of Conic Problems
E. Busseti, W. Moursi, S. Boyd
Most numerical methods for conic problems use the homogenous primal-dual embedding, which yields a primal-dual solution or a certificate establishing primal or dual infeasibility.…
Beaming electromagnetic (or heat-flux) instabilities from the interplay with the electron temperature anisotropies
S. M. Shaaban, M. Lazar, P. H. Yoon +1
In space plasmas kinetic instabilities are driven by the beaming (drifting) components and/or the temperature anisotropy of charged particles. The heat-flux instabilities are known…
Clarifying the solar wind heat-flux instabilities
S. M. Shaaban, M. Lazar, S. Poedts
In the solar wind electron velocity distributions reveal two counter-moving populations which may induce electromagnetic (EM) beaming instabilities known as heat flux instabilities…
A note on the equivalence of operator splitting methods
Walaa M. Moursi, Yuriy Zinchenko
This paper provides a comprehensive discussion of the equivalences between splitting methods. These equivalences have been studied over the past few decades and, in fact, have prov…
On the asymptotic behaviour of the Aragon Artacho-Campoy algorithm
Salihah Alwadani, Heinz H. Bauschke, Walaa M. Moursi +1
Aragón Artacho and Campoy recently proposed a new method for computing the projection onto the intersection of two closed convex sets in Hilbert space; moreover, they proposed in 2…
