Vortex beam generation with variable topological charge based on a spiral slit
Nanophotonics, 2019 We propose a vortex beam generator based on a nanometer spiral slit and explore the propagation rule of the topological charge. Compared to the common methods of generation of a vortex beam with a fixed topological charge, the optical vortex generated by

Effect of Air Jet Vortex Generators on the Shock Wave Boundary Layer Interaction of Transonic Wing
Aerospace, 2023 The interaction between shock waves and turbulent boundary layers (SBLI) is a common phenomenon in transonic and supersonic aircraft wings. In this study, we simulated the SBLI of a classical NACA0012 wing at an angle of attack (AOA) of 1.4° and Mach ...

Generalized Newton’s rings with vortex beams
Optics Express, 2022 The Newton’s rings are interference patterns with concentric rings, and Newton’s rings experiment is one of the most famous classic optics experiments. Here, we show that if we use a vortex beam, we can obtain generalized Newton’s rings. Unlike traditional Newton’s rings, the generalized ones are no longer concentric rings but spiral arms, and fork ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
