TL;DR: Positive and elementary stable nonstandard (PESN) finite-difference methods, having the same qualitative features as the corresponding continuous predator-prey models, are formulated and analyzed and lead to significant qualitative improvements in the behavior of the numerical solution.

TL;DR: Dynamical low-rank approximation is illustrated as an updating procedure in latent semantic indexing for information retrieval, in the compression of series of images, and in the solution of time-dependent partial differential equations, specifically on a blow-up problem of a reaction-diffusion equation in two and three spatial dimensions.

TL;DR: A technique for generating periodic structured grids for cascade simulations based on the Poisson equations is described, resulting in grids with low grid distortion by allowing both, block boundaries and grid points on physical boundaries, to move freely.

TL;DR: A state-feedback controller is developed that guarantees the L"2-gain of the mapping from the exogenous input noise to the regulated output is less than some prescribed value and the closed-loop system is D-stable.

TL;DR: The total QSSA (tQSSA), which is valid for a broader range of parameters covering both high and low enzyme concentrations, has been introduced in the last two decades and is extended to more complex reaction schemes, like fully competitive reactions, double phosphorylation, Goldbeter-Koshland switch and it is shown that for a very largerange of parameters the tSSA provides excellent fitting to the solutions of the full system.
