Spatio‐Temporal Diversity of Calcium Activity in Microglia

Glia, Volume 74, Issue 3, March 2026.
Ca2+ activity mostly occurs in microglial processes and stays localized. When it spreads, it often shows a directional bias and is constrained by branch points. Activity strongly relies on P2Y12 receptors and is shaped by neuronal activity. ABSTRACT Microglia, the brain's innate immune cells, possess complex, highly motile branched processes. These act

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, Volume 3, Issue 1, March 2026.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Wave Propagation in Non‐Uniform Media by Linear Expansion of the Refraction Law

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT The propagation of mechanical waves in an unbounded, non‐uniform medium can be described by using curvilinear coordinates centered at the source position. The Frenet coordinate system, with origin on a point riding a wave, is used as a basis for the curvilinear coordinates.

Algorithms for Wavefront Reconstruction

, 2005
Knowing the solution to Helmholtz equation in a narrow band, with a width of order wave length around a scatterer, we investigate the possibility to construct the wave fronts predicted by the asymptotic methods Geometrical Optics (GO) and Geometrical Theory of Diffraction (GTD).

Adaptive blind image deblurring and denoising

Scandinavian Journal of Statistics, Volume 53, Issue 1, Page 413-441, March 2026.
Abstract Blind image deblurring aims to reconstruct the original image from its blurred version without knowing the blurring mechanism. This is a challenging ill‐posed problem because there are infinitely many possible solutions. The ill‐posedness is further exacerbated if the blurring mechanism depends on the pixel location.
