Fourier ptychography microscopy for digital pathology

Journal of Microscopy, EarlyView.
Abstract Fourier ptychography microscopy (FPM) has made significant progress since its invention in 2013, thanks to its adaptable nature, high resolution, and vast field‐of‐view capabilities. FPM is used in various medical applications across multiple optical wavelengths, from automated digital pathology to radiology and ultraviolet label‐free imaging.

Observations and Model Simulations of Phase Heterogeneity in Arctic Clouds

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 13, 16 July 2025.
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.

Circularly Polarized Perovskite Photodetector with Photocurrent Dissymmetry Factors of up to 1.95 Enabled by Liquid Crystal

Advanced Functional Materials, Volume 35, Issue 27, July 3, 2025.
Photodetectors made using perovskite single crystals in combination with free‐standing cholesteric liquid crystal (CLC) polymer films exhibit photocurrent dissymmetry factors up to 1.95 for 520 nm circularly polarized light (CPL) excitation. The CPL spectral response of the photodetector is tunable over a broad range of wavelengths by tuning the ...

Phase Retrieval for Digital Holographic Microscopy With Defocused Holograms

IEEE Photonics Journal, 2018
A new phase retrieval technique in digital holographic microscopy (DHM) with three defocused holograms is proposed. Given the defocusing distance, the phase distributions of tested specimen can be reconstructed with a simple algebraic equation.

Digital Holographic Microscopy and Python

, 2019
Holograms are Interference, circular pattern of bright and dark lines surrounding an object due to light passage over it in 2D plane. The Hungarian-British physicist Dennis Gabor was awarded with Nobel Prize for inventing and applying this phenomenon for improving electron microscopy in 1971.

Dissecting Morphological and Functional Dynamics of Non‐Tumorigenic and Triple‐Negative Breast Cancer Cell Lines Using PCA and t‐SNE Analysis

Cancer Reports, Volume 8, Issue 7, July 2025.
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 ...
