AI Article Synopsis
- This work presents a novel self-healing ring protection method using spatial-division multiplexing in a network featuring a 3-node, 2-fiber ring setup.
- It utilizes advanced components like 4-core weakly-coupled multicore fibers and MEMS switches, allowing effective traffic management and real-time monitoring of fiber power levels.
- The scheme successfully maintains high line-side traffic throughput exceeding 120 Tb/s, demonstrating minimal performance loss, making it a robust solution for modern optical networks.
Article Abstract
This work demonstrates a spatial-division multiplexing self-healing ring protection scheme. A 3-node, 2-fiber ring with a recirculating length of 139.3 km is implemented using 4-core weakly-coupled multicore working and protection fibers and supported by core-pumped multicore amplifiers. Each node implements a spatial channel switching scheme with 8×8 traffic switches and arrays of 2×2 MEMS switches for ring protection switching with fiber bending taps to simultaneously monitor the power on all cores of the working and protection fibers. We achieve an average loss around 2 dB per network element along the protection path, which enables the use of ring protection with minimal performance impact. With this scheme, we demonstrate the protection of a line-side traffic throughput above 120 Tb/s using polarization-multiplexed 16-ary quadrature-amplitude modulation signals across the C-band.

End-user feedback early in product development is important for optimizing multipurpose prevention technologies for HIV and pregnancy prevention. We evaluated the acceptability of the 90-day dapivirine levonorgestrel ring (DPV-LNG ring) used for 14 days compared to a dapivirine-only ring (DVR-200mg) in MTN-030/IPM 041 (n = 23), and when used for 90 days cyclically or continuously in MTN-044/IPM 053/CCN019 (n = 25). We enrolled healthy, non-pregnant, HIV-negative women aged 18-45 in Pittsburgh, PA and Birmingham, AL (MTN-030 only).

Lipid phosphate phosphatase 3 (LPP3) is a membrane-bound enzyme that hydrolyzes lipid phosphates including the bioactive lipid, lysophosphatidic acid (LPA). Elevated circulating LPA production and cellular LPA signaling are implicated in obesity-induced metabolic and cardiac dysfunction. Deletion of LPP3 in the cardiomyocyte increases circulating LPA levels and causes heart failure and mitochondrial dysfunction in mice.

Hydrogels possessing appropriate adhesion and antibacterial properties have emerged as promising dressings for expediting wound healing, while also providing the convenience of visualizing the wound site to accurately monitor the healing process. In this study, we incorporated oxidized and degraded polydopamine nanoparticles into quaternized chitosan/oxidized dextran hydrogel QOP series, resulting in enhanced transmittance exceeding 95 % and adhesion strengths reaching up to 19.4 kPa.
