Experimental Study on Wavefront Distortion Correction in Atmospheric Turbulence Using Zernike-Wavelet Hybrid Basis

Applied Sciences
In adaptive optics systems, most methods rely on reconstruction techniques centered on regional or global orthogonal bases, which struggle to accommodate the multi-scale characteristics of atmospheric turbulence wavefronts.

A model of β‐adrenergic stimulation in human ventricular cells for tissue‐scale simulations of sympathetically modulated tachycardias

The Journal of Physiology, EarlyView.
Abstract figure legend Modelling β‐adrenergic stimulation in sympathetically remodelled ventricular substrates. Myocardial infarction could result in sympathetic remodelling in ventricular tissues, which affects arrhythmia dynamics. However sympathetic remodelling is challenging to control experimentally; therefore we created an ionic model that ...

Electrodiffusion in cardiac intercalated disc nanostructures alters cell–cell action potential transmission via ephaptic coupling: A model study

The Journal of Physiology, EarlyView.
Abstract figure legend Ephaptic phenomena in a high‐resolution model of the cardiac intercalated disc. Meshed representation of a tortuous intercalated disc that was generated based on electron and super‐resolution microscopy data. Na+ channels (red) and gap junctions (green) are heterogeneously distributed, with additional regions of reduced ion ...

3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, Volume 36, Issue 2, March 2026.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

Reconfigurable Metamirrors Based on Compliant Mechanisms

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.

Fluctuating Curvature and Actuation in 4D Printed Asymmetric Networks by Frontal Photopolymerization

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Asymmetric polymer networks, fabricated by frontal photopolymerization (FPP), are shown to exhibit curvature oscillations associated with monomer‐solvent exchanges during development and drying. We introduce a theoretical model for such dynamic curvature fluctuations and demonstrate the fabrication of bistable switches and self‐propelled materials that
