Exploring the Role of Stent Strut Geometry in Cellular Behavior: An In Vitro Chip Model to Understand In‐Stent Restenosis

Advanced Materials Interfaces, EarlyView.
An engineered in vitro platform mimicking stent strut cross‐sectional shapes reveals how geometry influences cell behavior. Sharp‐cornered geometries promote cell proliferation and matrix alignment, while rounded shapes reduce these effects. The findings align with clinical outcomes and suggest intracellular tension as a key driver, offering a ...

Proving Optical Anisotropy and Polarization Effects in β‐Ga2O3$\left(\text{Ga}\right)_{2} \left(\text{O}\right)_{3}$ Nanomembranes via X‐Ray Excited Optical Luminescence

Advanced Photonics Research, EarlyView.
In this study, the pronounced anisotropy in the optical properties of β‐Ga2O3 nanomembranes has been analized under a synchrotron nanoprobe. We have investigated the site‐specific contributions of distint Ga ions to the emission bands by combining polarization‐dependent X‐ray absorption near‐edge structure and X‐ray excited luminescence.

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review

Advanced Photonics Research, EarlyView.
Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

A Polarimetric First-Order Model of Soil Moisture Effects on the DInSAR Coherence

Remote Sensing, 2015
Changes in soil moisture between two radar acquisitions can impact the observed coherence in differential interferometry: both coherence magnitude |Υ| and phase Φ are affected. The influence on the latter potentially biases the estimation of deformations.
