Ecological systems with asymptotically stable equilibria may exhibit significant transient dynamics following perturbations. In some cases, these transient dynamics include the possibility of excursions away from the equilibrium before the eventual return; systems that exhibit such amplification of perturbations are called reactive. Reactivity is a common property of ecological systems, and the...

Currently, inconclusive evidence characterizes the thermally induced deformation of sands. In this context, role transient nature heat diffusion on sands has remained largely disregarded. This paper presents a theoretical and computational investigation dynamics characterizing under oedometric conditions. The study shows that heating rates determined by pore fluid pressure dissipation timescale...

Time-resolved photoelectron imaging has been utilized to probe the energetics and dynamics of the transient negative ion of the nucleobase uracil. This species was created through charge transfer from an iodide anion within a binary iodide-uracil complex using a UV pump pulse; the ensuing dynamics were followed by photodetachment with a near-IR probe pulse. The photoelectron spectra show two ti...
