Generation of Anisotropic Second‐Harmonic Petal‐Like Beams with NbOBr2 Holograms

open access: yesAdvanced Photonics Research, Volume 7, Issue 4, April 2026.
Highly anisotropic second‐harmonic petal‐like beams with different combinations of the topological charges of vortex beams are produced using ultrathin NbOBr2 holograms. These demonstrations provide a pathway toward the development of chip‐scale polarization‐sensitive functional optical devices for many applications.

Optically Transparent Space‐Selective Stacked Metasurface: Optimal Design for Asymmetrically Bidirectional Polarization Decomposition

open access: yesAdvanced Photonics Research, Volume 7, Issue 4, April 2026.
A momentous scheme to design the transparent metasurface using an accelerated elitist‐preserving genetic algorithm based on geometric coding method has been proposed in this paper. To verify the scheme, a transparently stacked metasurface has been designed, with which the characteristics of transparency, asymmetrically bidirectional polarization ...

Understanding the Workflows in Non‐Guided and Static Computer‐Assisted Implant Surgery

open access: yesClinical 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 ...

Futures of Everyday Life: A Qualitative Content Analysis of Future Personas in Scenarios

open access: yesFUTURES &FORESIGHT SCIENCE, Volume 8, Issue 1, April 2026.
ABSTRACT Scenario reports, holding a long‐standing tradition in foresight and futures studies, act as an essential document for organizations to prepare for possible, plausible, and alternative futures. Focusing on descriptions and representations of everyday life, we examined 29 future persona narratives from six publications—covering a wide field ...

Cell‐MICS: Detecting Immune Cells With Label‐Free Two‐Photon Autofluorescence and Deep Learning

open access: yesJournal of Biophotonics, Volume 19, Issue 4, April 2026.
We demonstrate multiphoton imaging with computational specificity for label‐free cell identification (cell‐MICS). Based on the intrinsic contrast of two‐photon induced autofluorescence from metabolic proteins, a deep neural network is able to distinguish various different immune cell types. The system's performance is stable and efficient.
