Design and Implementation of FTTP Using Gigabit Passive Optical Network Architecture in Ghana

Journal of Engineering, Volume 2025, Issue 1, 2025.
The main force behind the development of new access technologies is the rise in demand for high‐speed internet. Also, the rapid expansion of digital services in Ghana has necessitated the deployment of high‐speed broadband networks. Various technologies that use optical fiber as a transmission medium make up the fiber‐to‐the‐premises (FTTP) family of ...

Paraoxonase‐2 agonist vutiglabridin promotes autophagy activation and mitochondrial function to alleviate non‐alcoholic steatohepatitis

British Journal of Pharmacology, Volume 181, Issue 19, Page 3717-3742, October 2024.
Abstract Background and Purpose Only limited therapeutic agents have been developed for non‐alcoholic steatohepatitis (NASH). Glabridin, a promising anti‐obesity candidate, has only limited druggability due to its low in vivo chemical stability and bioavailability.

Performance Analysis of DP‐QAM‐Based Optical OFDM PON Employing Optical Multicarrier

Journal of Engineering, Volume 2024, Issue 1, 2024.
This work proposes a new hybrid bidirectional standard single mode fiber (SSMF)/free space optical (FSO) dual polarization quadrature amplitude modulation (DP‐QAM) employing optical orthogonal frequency division multiplexing (OFDM). An optical multicarrier generator (OMG) source is utilized. The suggested model is simulated using VPI photonics software.
