ANALYSIS OF THE CROSSTALK IN OPTICAL AMPLIFIERS [PDF]
ICTACT Journal on Communication Technology, 2013 In this work, we tried to analyze the crosstalk in optical amplifiers. For mathematical analysis, we have considered the Gain (G) for different amplifiers as 35 dB, 18 dB and 26 dB, respectively.

Long-haul optical transmission link using low-noise phase-sensitive amplifiers
Nature Communications, 2018 Phase-sensitive amplifiers are known for low-noise amplification and nonlinearity mitigation, but their long-haul implementation is challenging. The authors use these amplifiers to show a long-haul optical link with a 5.6-times reach improvement over ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
