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.

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

An Algebraic Study of Parametric Stokes Phenomena
Studies in Applied Mathematics, Volume 157, Issue 1, July 2026.ABSTRACT We investigate geometric aspects of co‐equational parametric resurgence, by studying physical problems whose formal asymptotic solutions give rise to Borel transforms lying on an algebraic curve. This perspective allows us to elucidate concepts unique to parametric resurgence such as singularity structures, (virtual) turning points, and the ...

On the Gierer-Meinhardt System with Saturation [PDF]
, 2004 We consider the following shadow Gierer-Meinhardt system with saturation: \left\{\begin{array}{l} A_t=\epsilon^2 \Delta A -A + \frac{A^2}{ \xi (1+k A^2)} \ \ \mbox{in} \ \Omega \times (0, \infty),\\ \tau \xi_t= -\xi +\frac{1}{|\Omega|} \int_\Om A^2 ...

Exponential stability for a class of singularly perturbed It\^{o} differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2000 The problem of exponential stability in mean square of the zero solution for a class of singularly perturbed system of Itô differential equations is investigated. Estimates of the block components of the fundamental random matrix are provided.

Decomposition and stability of linear singularly perturbed systems with two small parameters
Karpatsʹkì Matematičnì Publìkacìï, 2021 In the domain $\Omega =\left\{\left(t,\varepsilon _{1}, \varepsilon _{2} \right): t\in {\mathbb R},\varepsilon _{1}>0, \varepsilon _{2} >0\right\}$, we consider a linear singularly perturbed system with two small parameters \[ \left\{ \begin{array}{l ...

MedComm – Oncology, Volume 5, Issue 2, June 2026.CHD4 plays an essential role as an epigenetic regulator in the pathogenesis of multiple myeloma. The chromatin remodeling protein initially resolves G‐quadruplex (G4) secondary structures within the c‐Myc promoter region, thereby enhancing chromatin accessibility and promoting transcriptional activation.

Stabilization of a class of singularly perturbed switched systems
2023 American Control Conference (ACC), 2023 In this paper, we address the control of a class of switched systems cast in the framework of singularly perturbed systems. The class of switched systems that we deal with here is a particular case of switched affine systems where the state matrices are the same for all modes. These systems have been studied in the literature, wherein control design is
