Wavelength Division Multiplexing (WDM) [PDF]

, 2018
Postupak valnog multipleksiranja značajno povećava kapacitet optičkog vlakna. Kod svjetlovodnih prijenosnih sustava razlikuju se CWDM i DWDM izvedba, a svaka izvedba zahtjeva određene komponente za ostvarenje prijenosa signala.

A novel space division multiplexing system for free space optical communications [PDF]

arXiv, 2013
We propose a novel space division multiplexing (SDM) technique based on spatial phase encoding, which may provide a new perspective beyond the conventional SDM in free space optical communications, such as multiplexing of orbital angular momentum (OAM).

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

, 2022
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.

The Hypoxia‐Associated High‐Risk Cell Subpopulation Distinctly Enhances the Progression of Glioma

Advanced Science, EarlyView.
This study suggests the potential roles of a novel hypoxia‐associated CDC20+KIF20A+PTTG1+ cell subpopulation in glioma progression. This high‐risk glioma cell subpopulation is therapeutically vulnerable to glioma progression and may play important roles in glioma standard‐of‐care therapeutic resistance.

Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

International Journal of Satellite Communications and Networking, EarlyView., 2023
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

Plac1+ Tumor Cell‐Treg Interplay Supports Tumorigenesis and Progression of Head and Neck Cancer

Advanced Science, EarlyView.
Meng et al. screen genes in the CTAs family and find Plac1 is specifically expressed in head and neck squamous cell carcinoma (HNSCC) cells. They reveal that Plac1 expression promotes HNSCC progression directly by activating PI3K/AKT signaling pathway.

Hyperbolic Topological Quantum Sources

Advanced Science, EarlyView.
In this work, we present the experimental realization of hyperbolic topological quantum sources on silicon chips, which only require fewer resources to achieve a higher brightness. It shows a high utilization efficiency and a strong robustness. Abstract Robust Integrable Quantum Optical Sources, Constructed by Topological Boundary States, Are Crucial ...
