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.

Ptychographic analysis of human bone marrow‐derived mesenchymal stem cell morphology: The impact of cell senescence

Journal of Microscopy, EarlyView.
Abstract Mesenchymal stem cells (MSC) undergo replicative senescence, a state of irreversible cell cycle arrest that limits their utility in regenerative medicine applications. To identify novel markers of senescence useful to enhance the quality of MSC‐based therapies, we compared young and senescent human bone marrow‐derived mesenchymal stem cells ...

Analytical solution of the classical Rayleigh length definition, including truncation at arbitrary values

Journal of Microscopy, EarlyView.
Abstract We present the analytical solution to the diffraction integral that describes the Rayleigh length for a focused Gaussian beam with any value of a spherical truncating aperture. This exact solution is in precise agreement with numerical calculations for the light distribution in the near focal area.

Complete‐coverage path planning for surface inspection of cable‐stayed bridge tower based on building information models and climbing robots

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Climbing robots present transformative potential for automated structural inspections, yet their deployment remains limited by the reliance on manual control due to the absence of effective environment perception and path‐planning solutions.

Accommodative behaviour and retinal defocus of children during prolonged viewing of electronic devices while wearing dual‐focus myopia control soft contact lenses

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose Chronic hyperopic defocus from inadequate accommodation during near tasks may be associated with axial eye growth. This study examined accommodative behaviour and retinal defocus in myopic and emmetropic children after 1 h of continuous electronic device use.

Predicting patient‐reported quality of vision through multifocal optics

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To explore the agreement between computationally modelled point‐spread functions (PSFs) and multifocal soft contact lens wearers' descriptions of image quality. Methods In Phase 1, participants were fitted with a single vision soft contact lens (SCL) in the left eye, and four different multifocal (MF) SCLs in the right eye in ...
