Evidence for the Magnetic Breakout Model in an Equatorial Coronal-hole Jet (2018)
Journal Article
Kumar, P., Karpen, J. T., Antiochos, S. K., Wyper, P. F., DeVore, C. R., & DeForest, C. E. (2018). Evidence for the Magnetic Breakout Model in an Equatorial Coronal-hole Jet. Astrophysical Journal, 854(2), Article 155. https://doi.org/10.3847/1538-4357/aaab4f

Small, impulsive jets commonly occur throughout the solar corona, but are especially visible in coronal holes. Evidence is mounting that jets are part of a continuum of eruptions that extends to much larger coronal mass ejections and eruptive flares....

On the rates of decay to equilibrium in degenerate and defective Fokker–Planck equations (2018)
Journal Article
Arnold, A., Einav, A., & Wöhrer, T. (2018). On the rates of decay to equilibrium in degenerate and defective Fokker–Planck equations. Journal of Differential Equations, 264(11), 6843-6872. https://doi.org/10.1016/j.jde.2018.01.052

We establish sharp long time asymptotic behaviour for a family of entropies to defective Fokker–Planck equations and show that, much like defective finite dimensional ODEs, their decay rate is an exponential multiplied by a polynomial in time. The no... Read More about On the rates of decay to equilibrium in degenerate and defective Fokker–Planck equations.

Forward Modeling of Coronal Mass Ejection Flux Ropes in the Inner Heliosphere with 3DCORE (2018)
Journal Article
Möstl, C., Amerstorfer, T., Palmerio, E., Isavnin, A., Farrugia, C., Lowder, C., …Boakes, P. (2018). Forward Modeling of Coronal Mass Ejection Flux Ropes in the Inner Heliosphere with 3DCORE. Space Weather, 16(3), 216-229. https://doi.org/10.1002/2017sw001735

Forecasting the geomagnetic effects of solar storms, known as coronal mass ejections (CMEs), is currently severely limited by our inability to predict the magnetic field configuration in the CME magnetic core and by observational effects of a single...

Hopf solitons on compact manifolds (2018)
Journal Article
Ward, R. (2018). Hopf solitons on compact manifolds. Journal of Mathematical Physics, 59(2), Article 022904. https://doi.org/10.1063/1.5006891

Hopf solitons in the Skyrme-Faddeev system on R3 typically have a complicated structure, in particular when the Hopf number Q is large. By contrast, if we work on a compact 3-manifold M, and the energy functional consists only of the Skyrme term (the... Read More about Hopf solitons on compact manifolds.

Matrix supergroup Chern-Simons models for vortex-antivortex systems (2018)
Journal Article
Okazaki, T., & Smith, D. J. (2018). Matrix supergroup Chern-Simons models for vortex-antivortex systems. Journal of High Energy Physics, 2018(2), Article 118. https://doi.org/10.1007/jhep02%282018%29119

We study a U(N |M ) supermatrix Chern-Simons model with an SU(p|q) internal symmetry. We propose that the model describes a system consisting of N vortices and M antivortices involving SU(p|q) internal spin degrees of freedom. We present both classic...

Elastic proton-proton scattering at 13 TeV (2018)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2018). Elastic proton-proton scattering at 13 TeV. Physical Review D, 97(3), Article 034019. https://doi.org/10.1103/physrevd.97.034019

The predictions of a model which was tuned in 2013 to describe the elastic and diffractive p p - and/or p ¯ p -data at collider energies up to 7 TeV are compared with the new 13 TeV TOTEM results. The possibility of the presence of an odd-signature O... Read More about Elastic proton-proton scattering at 13 TeV.

Reliability sensitivity analysis of coherent systems based on survival signature (2018)
Journal Article
Huang, X., & Coolen, F. (2018). Reliability sensitivity analysis of coherent systems based on survival signature. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 232(6), 627-634. https://doi.org/10.1177/1748006x18754974

The reliability sensitivity can be used to rank distribution parameters of system components concerning their impacts on the system’s reliability. Such information is essential to purposes such as component prioritization, reliability improvement, an...

On the Variational Formulation of Some Stationary Second-Order Mean Field Games Systems (2018)
Journal Article
Mészáros, A. R., & Silva, F. J. (2018). On the Variational Formulation of Some Stationary Second-Order Mean Field Games Systems. SIAM Journal on Mathematical Analysis, 50(1), 1255-1277. https://doi.org/10.1137/17m1125960

We consider the variational approach to prove the existence of solutions of second-order stationary Mean Field Games systems on a bounded domain $\Omega\subseteq {\mathbb R}^{d}$ with Neumann boundary conditions and with and without density constrain...

Perfectly ordered quasicrystals and the Littlewood conjecture (2018)
Journal Article
Haynes, A., Koivusalo, H., & Walton, J. (2018). Perfectly ordered quasicrystals and the Littlewood conjecture. Transactions of the American Mathematical Society, 370(7), 4975-4992. https://doi.org/10.1090/tran/7136

Linearly repetitive cut and project sets are mathematical models for perfectly ordered quasicrystals. In a previous paper we presented a characterization of linearly repetitive cut and project sets. In this paper we extend the classical definition of... Read More about Perfectly ordered quasicrystals and the Littlewood conjecture.
