Rethinking Extracellular Vesicle Signaling
Advanced Materials, EarlyView.Extracellular vesicles enable cell communication beyond intracellular cargo delivery. This perspective highlights two plausible surface‐based signaling modes: “bind‐and‐stay” and “bind‐and‐leave.” Transient binding to multiple cells challenges the one‐vesicle‐one‐cell model.

Use of Computer-Generated Holograms in Security Hologram Applications [PDF]
Latvian Journal of Physics and Technical Sciences, 2016 Abstract The article discusses the use of computer-generated holograms (CGHs) for the application as one of the security features in the relief-phase protective holograms. An improved method of calculating CGHs is presented, based on ray-tracing approach in the case of interference of parallel rays.

Cross talk in phase-coded holographic memories [PDF]
, 1993 The cross talk between holograms multiplexed with Walsh-Hadamard phase codes is analyzed. Each hologram is stored with a reference beam that consists of N phase-coded plane waves. The signal-to-noise ratio (SNR) is calculated for a recording schedule for

Arbitrary Total Angular Momentum Vectorial Holography Using Bi-Layer Metasurfaces. [PDF]
Adv MaterA bi‐layer metasurface platform is presented for arbitrary total angular momentum vectorial holography, where polarization and orbital angular momentum are exploited as independent multiplexing dimensions. By overcoming symmetry limitations of single‐layer designs, the approach generates distinct vectorial holographic images for each orthogonal TAM ...

Holographic data storage in a DX-center material [PDF]
, 1997 We report on the optical storage of digital data in a semiconductor sample containing DX centers. The diffraction efficiency and the bit-error-rate performance of multiplexed data images are shown to agree well with a simple model of the material ...

Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons
Advanced Optical Materials, EarlyView.Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic
