Sign changing solutions for elliptic equations with critical growth in cylinder type domains
Pedro M. Girão, Miguel Ramos
We prove the existence of positive and of nodal solutions for , , where and , for a class of open subsets $Ω…
An exploration of the effectiveness of artificial mini-magnetospheres as a potential Solar Storm shelter for long term human space missions
Ruth Bamford, Barry Kellett, John Bradford +7
In this paper we explore the effectiveness of an artificial mini-magnetosphere as a potential radiation shelter for long term human space missions. Our study includes the differenc…
On the L^2-metric of vortex moduli spaces
J. M. Baptista
We derive general expressions for the Kaehler form of the L^2-metric in terms of standard 2-forms on vortex moduli spaces. In the case of abelian vortices in gauged linear sigma-mo…
Diversity of supernovae Ia determined using equivalent widths of Si II 4000
V. Arsenijevic, S. Fabbro, A. M. Mourao +1
Spectroscopic and photometric properties of low and high-z supernovae Ia (SNe Ia) have been analyzed in order to achieve a better understanding of their diversity and to identify p…
Direct Acceleration of Ions With Variable-frequency Lasers
F. Peano, J. Vieira, R. A. Fonseca +3
A method is proposed for producing monoergetic, high-quality ion beams in vacuum, via direct acceleration by the electromagnetic field of two counterpropagating, variable-frequency…
