Observations and Model Simulations of Phase Heterogeneity in Arctic Clouds
Abstract Mixed‐phase clouds (MPCs) play a key role in Earth's radiation budget particularly in the Arctic where they are ubiquitous year‐round. An important characteristic of MPCs is how the cloud phases are mixed, which affects interactions between ice and liquid.

Single-exposure full-field multi-depth imaging using low-coherence holographic multiplexing
We present a new interferometric imaging approach that allows for multiple-depth imaging in a single acquisition, using off-axis low-coherence holographic multiplexing. This technique enables sectioned imaging of multiple slices within a thick sample, in

Reconstructing Three‐Dimensional Optical Anisotropy with Tomographic Müller‐Polarimetric Microscopy
Tomographic Müller polarimetric microscopy is a novel imaging technique that resolves 3D birefringent properties of bulky samples, unveiling hierarchical nanostructures at microscopic resolution. Based on incoherent visible‐light polarimetry, it achieves experimental simplicity by eliminating phase measurements.

Speckle Reduction in Digital Holography by Fast Logistic Adaptive Non-Local Means Filtering
Digital holography is a promising imaging technology. However, there is speckle noise in the reconstructed image of a digital hologram. Speckle degrades the quality of the reconstructed image.

Achromatic 3D Multi‐Color Orbital Angular Momentum Holography
This work presents an achromatic 3D multicolor orbital angular momentum (OAM) holography based on spatial multiplexing. By integrating wavelength‐specific lens functions onto monochromatic Fourier OAM‐dependent holograms and high‐resolution spatial discretization and interleaving via two‐photon lithography (TPL), the approach addresses axial chromatic ...

Depth-filtered digital holography
We introduce depth-filtered digital holography (DFDH) as a method for quantitative tomographic phase imaging of buried layers in multilayer samples. The procedure is based on the acquisition of multiple holograms for different wavelengths. Analyzing the intensity over wavelength pixel wise and using an inverse Fourier transform leads to a depth-profile

ABSTRACT Background Triple‐negative breast cancer (TNBC) poses significant challenges due to its aggressive nature and lack of targeted therapies. Understanding the cellular behaviors of TNBC is crucial for developing effective treatments. Aims This study aims to compare the morphological characteristics of non‐tumorigenic MCF10A and aggressive MDA‐MB ...
