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

open access: yesAdvanced Photonics Research, Volume 6, Issue 10, October 2025.
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 ...

Autofocused 3D Classification of Cryoelectron Subtomograms [PDF]

open access: yesStructure, 2014
Classification of subtomograms obtained by cryoelectron tomography (cryo-ET) is a powerful approach to study the conformational landscapes of macromolecular complexes in situ. Major challenges in subtomogram classification are the low signal-to-noise ratio (SNR) of cryo-tomograms, their incomplete angular sampling, the unknown number of classes and the

Utility of whole‐slide imaging for rapid evaluation of thyroid FNA: A multireader prospective study

open access: yesCancer Cytopathology, Volume 133, Issue 9, September 2025.
Abstract Background Rapid on‐site evaluation (ROSE) of thyroid fine‐needle aspiration biopsy (FNAB) improves diagnostic adequacy and facilitates ancillary molecular testing. In this prospective, multireader study, the authors evaluated the feasibility of using whole‐slide images (WSIs) for ROSE to determine specimen adequacy and preliminary ...

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

open access: yesAdvanced Science, Volume 12, Issue 31, August 21, 2025.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

Intraspecific Variation in Dorsal Colour Patterns of Amphibolurus muricatus Lizards From the Perspective of Relevant Observers

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This study examined dorsal pattern variations across the geographic range of an Australian lizard using multispectral photography and visual models for lizards and avian predators. Findings reveal differences in dorsal colouration based on sex, body size, genetic clades and habitat type.

Wide‐Field Bond Quality Evaluation Using Frequency Domain Thermoreflectance with Deep Neural Network Feature Reconstruction

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 13, July 14, 2025.
In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.
