Focus detection in digital holography by cross-sectional images of propagating waves [PDF]
, 2014 In digital holography, computing a focused image of an object requires a prior knowledge of the distance of the object from the camera. When this distance is not known, it is necessary to repeat the image reconstruction at a range of distances followed ...

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

Advanced 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 ...

Dynamic Control of Circular Airy Beams With Linear Optical Potentials
IEEE Photonics Journal, 2012 We investigate the propagation dynamics of radially symmetric, circular Airy beams through a medium having linear optical potentials. On the basis of analytic expressions and numerical calculations, we show that “off-axis” autofocusing can ...

An Extended Virtual Aperture Imaging Model for Through-the-wall Sensing and Its Environmental Parameters Estimation [PDF]
, 2014 Through-the-wall imaging (TWI) radar has been given increasing attention in recent years. However, prior knowledge about environmental parameters, such as wall thickness and dielectric constant, and the standoff distance between an array and a wall, is ...

Ecology 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.

Advanced 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.

Autofocusing drift tube linac envelopes
Physical Review Accelerators and Beams, 2021 To date, beam dynamics studies and design of combined zero degree drift tube linac (DTL) structures (Kombinierte Null Grad Struktur; KONUS) have only been carried out in multiparticle codes. Quantities such as the beam envelopes are obtained by averaging
