High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array
Laser &Photonics Reviews, EarlyView.A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,

3D Dielectric Chiral Metamaterials Achieving Nondispersive Near‐Zero Ellipticity
Laser &Photonics Reviews, EarlyView.Broadband and high‐transmission‐efficiency optical activity (OA) is a critical functionality for numerous applications but is challenging to achieve. By engineering circularly polarized (CP) eigenstates in three‐dimensional (3D) dielectric helices, a 3D‐printed ceramic metamaterial is demonstrated for broadband OA with nondispersive near‐zero ...

Design of a time‐delay‐compensated monochromator for the ARPES endstation at S3FEL
Journal of Synchrotron Radiation, EarlyView.This work presents the design and expected performance of an Angle‐Resolved Photoemission Spectroscopy (ARPES) branchline at the Shenzhen Superconducting Soft X‐ray Free Electron Laser (S3FEL). The branchline employs a symmetric time‐delay‐compensated monochromator (TDCM) for spectral selection and pulse duration preservation.

Geophysical Prospecting, EarlyView.Abstract The knowledge of the local slope field of prestack seismic data is essential in several seismic signal processing tasks. Building on our previous slope‐assisted, physics‐informed seismic interpolation framework, dubbed PINNslope, we introduce a series of enhancements that elevate the framework's versatility.

Methods in Ecology and Evolution, EarlyView.Abstract Colonies of pure bacterial strains are highly dense cellular structures organised in distinct and typical arrangements. The size, shape and variability of bacterial colonies are strongly species‐dependent and also influenced by environmental conditions. However, the spatial organization of individual cells is unknown for most strains.

Presbyopia Correction in Lens Replacement Surgery: A Review
Clinical &Experimental Ophthalmology, EarlyView.ABSTRACT Presbyopia affects approximately 1.8 billion individuals globally, posing significant challenges as life expectancy and near‐vision demands, particularly with mobile phone use, grow. Addressing presbyopia during lens replacement surgery has become a key focus for cataract surgeons, aiming to reduce dependence on corrective eyewear. This review

Real‐Time Rendering Framework for Holography
Computer Graphics Forum, EarlyView.Abstract With the advent of holographic near‐eye displays, the need for rendering algorithms that output holograms instead of color images emerged. These holograms usually encode phase maps that alter the phase of coherent light sources such that images result from diffraction effects.

Factors affecting the mean electrical axis of the heart in trained Thoroughbreds
Equine Veterinary Education, EarlyView.Summary Background Assuming that the ventricular myocardium of horses is subjected to exercise‐induced hypertrophy, we hypothesised that the mean electrical axis (MEA) of the heart would change. Objectives To define a longitudinal study to detect any changes in the direction of the MEA in Thoroughbred horses using ECG.
