Automatic Compressive Sensing of Shack–Hartmann Sensors Based on the Vision Transformer
PhotonicsShack–Hartmann wavefront sensors (SHWFSs) are crucial for detecting distortions in adaptive optics systems, but the accuracy of wavefront reconstruction is often hampered by low guide star brightness or strong atmospheric turbulence.

One Metasurface for Four‐Channel Terahertz Wavefront Manipulation Based on Vanadium Dioxide
Advanced Physics Research, Volume 5, Issue 4, April 2026.This article presents a thermally reconfigurable metasurface utilizing vanadium dioxide (VO2) to dynamically switch between four independent wavefront‐manipulation channels. By synergizing geometric and propagation phases, the platform enables spin‐decoding for circularly polarized waves and polarization multiplexing for linearly polarized waves ...

Understanding the Workflows in Non‐Guided and Static Computer‐Assisted Implant Surgery
Clinical and Experimental Dental Research, Volume 12, Issue 2, April 2026.ABSTRACT Contemporary implant dentistry aims to achieve long‐term biological, esthetic, and functional successful outcomes. Thus, instrumental to this aim is designing an integrated system in which the supported prosthesis & components, anatomical and phenotypical tissue characteristics, and the fixture act synergistically to maintain peri‐implant ...

Mode‐Locked Pulse Generation in Plasmonic Lattices
Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...
