Homodyne coherent detection of ASK and PSK signals performed by a subcarrier optical phase-locked loop [PDF]

open access: yes, 2005
Optical transmission systems based on homodyne coherent detection of 2-ASK and pilot carrier 2-PSK signals have been implemented. ASK data has been transmitted at 2.5 Gbps, while 2.5 Gbps and 10 Gbps PSK systems have been tested.

Regulating liquid and solid-state electrolytes for solid-phase conversion in Li–S batteries

open access: yes, 2022
The solid-phase conversion mechanism in lithium–sulfur (Li–S) batteries has emerged with many attractive advantages such as avoiding the parasitic “shuttle effect” of soluble polysulfides and allowing lean electrolyte operating conditions.

S‐Phase phosphorylation of lamin B2 [PDF]

open access: yesFEBS Letters, 1995
Lamin B2 modification in synchronously dividing populations of human diploid fibroblasts was determined by 2‐dimensional gel electrophoresis and [32P]orthophosphate labelling. In quiescent (G0) and G1 cultures of HDF, lamin B2 migrated as 2 spots on 2‐dimensional gels.

Quadratic phase S-Transform: Properties and uncertainty principles

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
In this paper, a novel quadratic phase S-transform (QPST) is proposed, by generalizing the S-transform (ST) with five parameters a, b, c,d and e. QPST displays the time and quadratic phase domain-frequency information jointly in the time-frequency plane.
