A CASCADE OF WNT, EDA, AND SHH SIGNALING IS ESSENTIAL FOR TOUCH DOME MERKEL CELL DEVELOPMENT.



Spectral self-imaging of optical orbital angular momentum modes

The Talbot self-imaging effect is mostly present in the forms of space or time, or in the frequency domain by the Fourier duality.Here, we disclose a new spectral Talbot effect arising in optical orbital angular momentum (OAM) modes.The effect occurs in the context of petal-like beams, which are typically constructed from a number of in-phase equid
