Spatial and Wavelength Division Joint Multiplexing System Design for MIMO-OFDM Visible Light Communications

IEEE Access
The low-pass characteristics of front-end elements including light-emitting diodes (LEDs) and photodiodes (PDs) limit the transmission data rate of visible light communication (VLC) and Light Fidelity (LiFi) systems.

Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber

Advanced Photonics Research, EarlyView.
Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

Cluster Synchronization in Multiplex Networks [PDF]

arXiv, 2014
We study the impact of interaction of nodes in a layer of a multiplex network on the dynamical behavior and cluster synchronization of these nodes in other layers. We find that nodes interactions in one layer affects the cluster synchronizability of another layer in many different ways.

Analysis of Band Effects in One‐Dimensional Periodic Lattices Using an Enhanced Homogenization Method

Advanced Photonics Research, EarlyView.
An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

Advanced Photonics Research, EarlyView.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Communicability reveals a transition to coordinated behavior in multiplex networks [PDF]

, 2013
We analyse the flow of information in multiplex networks by means of the communicability function. First, we generalize this measure from its definition from simple graphs to multiplex networks. Then, we study its relevance for the analysis of real-world systems by studying a social multiplex where information flows using formal/informal channels and ...

Inhibition of Aberrant Activated Fibroblast‐Like Synoviocytes in Rheumatoid Arthritis by Leishmania Peptide via the Regulation of Fatty Acid Synthesis Metabolism

Advanced Science, EarlyView.
LACK156‐173 is internalized into RA‐FLSs via CAPN2‐mediated endocytosis and inhibits the aggressive phenotype of RA‐FLSs by restoring dysregulated fatty acid synthesis metabolism mediated by overexpressed FASN. The findings suggest that targeting the restoration of fatty acid metabolism could potentially alleviate synovial invasion and joint damage in ...
