Spikes for the two-dimensional Gierer-Meinhardt system: The weak coupling case [PDF]
, 2001 In this paper, we rigorously prove the existence and stability of multiple-peaked patterns for the singularly perturbed Gierer-Meinhardt system in a two dimensional domain which are far from spatial homogeneity.

Aging Cell, Volume 25, Issue 10, October 2026.Hepatocyte‐specific GHR ablation is associated with hepatic and age‐related pathologies, triggering adipose‐liver crosstalk via elevated circulating GH and subsequent CD36‐dependent hepatic steatosis. This loss impairs STAT5b phosphorylation and enhances PPARγ nuclear activation, upregulating Pdk4 and Cd36 to drive mitochondrial dysfunction and ectopic

Limnology and Oceanography, Volume 71, Issue 9, September 2026.Abstract B‐vitamins are organic cofactors required by prokaryotic and eukaryotic planktonic cells; their availability impacts aquatic microbial communities and associated biogeochemistry. Despite their ecological importance, B‐vitamin dynamics and their relationships to plankton composition in estuaries are unclear, limiting our understanding of ...

IEEE Access, 2022 This paper focuses on the $H\infty $ observer-based control problem for discrete-time singularly perturbed systems (DTSPSs) with nonlinear disturbances. The main contributions of this paper include three aspects: First, a proper observer is constructed.

Economic Record, Volume 102, Issue 338, Page 323-349, September 2026.We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Water Resources Research, Volume 62, Issue 8, August 2026.Abstract Ice forms seasonally in mid‐latitude soils, and permanently as permafrost in arctic sediments. Ice blocks some of the pore space, altering the flow of both liquid water and gas. Here, we determine the equilibrium position of ice in a three‐phase ice/water/gas system by minimizing the free energy of the system.

Relaxation Cycles in a Generalized Neuron Model with Two Delays
Моделирование и анализ информационных систем, 2013 A method of modeling the phenomenon of bursting behavior in neural systems based on delay equations is proposed. A singularly perturbed scalar nonlinear differentialdifference equation of Volterra type is a mathematical model of a neuron and a separate ...
