An adaptive scheme for the optimization of damping positions by decoupling controllability spaces in vibrational systems

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 3, March 2026.
Abstract In this work, the problem of optimizing damper positions in vibrational systems is investigated. The objective is to determine the positions of external dampers in such a way that the influence of the input on the output is minimized. The energy response serves as an optimization criterion, whose computation involves solving Lyapunov equations.

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...

Rare Event Sampling for Moving Targets: Extremes of Temperature and Daily Precipitation in a General Circulation Model

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Extreme weather events epitomize high cost: to society through their physical impacts, and to computer servers that simulate them to assess risk and advance physical understanding. It costs hundreds of simulation years to sample a few once‐per‐century events with straightforward model integration, but that cost can be much reduced with rare ...

Numerical Study of a Nonlocal Nonlinear Schrödinger Equation (MMT Model)

open access: yesStudies in Applied Mathematics, Volume 156, Issue 3, March 2026.
ABSTRACT In this paper, we study a nonlocal nonlinear Schrödinger equation (MMT model). We investigate the effect of the nonlocal operator appearing in the nonlinearity on the long‐term behavior of solutions, and we identify the conditions under which the solutions of the Cauchy problem associated with this equation are bounded globally in time in the ...

Modulation of slow and fast oscillations by direct current stimulation in the cerebral cortex in vitro

open access: yesThe Journal of Physiology, Volume 604, Issue 5, Page 2131-2151, 1 March 2026.
Abstract figure legend Direct‐current (DC) electric fields modulate spontaneous slow oscillations in cerebral cortex slices in vitro. Schematic of the in vitro preparation (upper panels). Spontaneous slow oscillations (SO; <1 Hz) consisting of alternating Up (active) and Down (silent) states were observed under control conditions.
