Oxidative Medicine and Cellular Longevity, Volume 2021, Issue 1, 2021., 2021 The current work was aimed at evaluating the ameliorative role of quercetin (QR) on the possible toxicity of Red Bull energy drink (RB‐Ed) in the cerebral cortex of rats. To achieve the goal, the rats were allocated into 4 groups. The first group received distilled water as control.

The Escape of Sisyphus or What “Post NG-PON2” Should Do Apart from Neverending Capacity Upgrades
Photonics, 2014 The primary design goal of (r)evolutionary NG-PON1&2 was the provisioning of an ever increasing capacity to cope with video-dominated traffic and handle the explosion of mobile data traffic by means of offloading.

TWDM-PON With Signal Remodulation and Rayleigh Noise Circumvention for NG-PON2
IEEE Photonics Journal, 2013 We propose and demonstrate a 40-Gb/s (4 × 10 Gb/s) downstream and 10-Gb/s (4 × 2.5 Gb/s) upstream time-wavelength-division-multiplexed passive optical network (TWDM-PON) using signal remodulation. Here, a downstream differential-phase-shift-
