Steady state solutions for the Gierer-Meinhardt system in the whole space
Marius Ghergu
We are concerned with the study of positive solutions to the Gierer-Meinhardt system $$ \begin{cases} \displaystyle -Δu+λu=\frac{u^p}{v^q}+ρ(x) &\quad\mbox{ in }\mathbb{R}^N\, , N\…
Difference ascent sequences
Mark Dukes, Bruce Sagan
Let alpha = a_1 a_2 ... a_n be a sequence of nonnegative integers. The ascent set of alpha, Asc(alpha), consists of all indices k where a_{k+1} > a_k. An ascent sequence is alpha w…
Advancing Post Hoc Case Based Explanation with Feature Highlighting
Eoin Kenny, Eoin Delaney, Mark Keane
Explainable AI (XAI) has been proposed as a valuable tool to assist in downstream tasks involving human and AI collaboration. Perhaps the most psychologically valid XAI techniques…
Ancillary Services in Power System Transition Toward a 100% Non-Fossil Future: Market Design Challenges in the United States and Europe
Luigi Viola, Saeed Nordin, Daniel Dotta +3
The expansion of variable generation has driven a transition toward a 100\% non-fossil power system. New system needs are challenging system stability and suggesting the need for a…
A Simultaneous Dual-site Technosignature Search Using International LOFAR Stations
Owen A. Johnson, Vishal Gajjar, Evan F. Keane +19
The Search for Extraterrestrial Intelligence aims to find evidence of technosignatures, which can point toward the possible existence of technologically advanced extraterrestrial l…
Three- and four-wave resonances in the nonlinear quadratic Kelvin lattice
Andrea Pezzi, Tiziana Comito, Miguel D. Bustamante +1
In this paper we investigate analytically and numerically the nonlinear Kelvin lattice, namely a chain of masses and nonlinear springs, as in the alpha-Fermi-Pasta-Ulam-Tsingou (FP…
