Cascaded generalised-K fading channel

IET Communications, 2010
A versatile fading distribution that generalises many commonly used models for multi-path and shadow fading is the so-called generalised-K (KG) distribution. By considering the product of N independent but not necessarily identically distributed (n.i.d.) squared KG random variables (RVs), we derive exact closed-form expressions for the moment ...

Statistics of cascaded Rayleigh fading channels with arbitrary correlation [PDF]

IET Communications, 2020
Exact expressions for the probability density function (PDF) and cumulative distribution function (CDF) of cascaded Rayleigh fading channels with arbitrary correlation but not necessarily identically distributed are derived. Furthermore, the PDF and CDF of the instantaneous signal‐to‐noise ratio are obtained.

Upper bound on the capacity of a cascade of nonlinear and noisy channels [PDF]

2015 IEEE Information Theory Workshop (ITW), 2015
The main change is to define the noise as bandlimited already in (8) rather than before (15).

Elimination of the chirp of optical pulses through cascaded nonlinearities in periodically poled lithium niobate waveguides

, 2010
We propose and demonstrate a novel method for the elimination of arbitrary frequency chirp from short optical pulses. The technique is based on the combination of two cascaded second-order nonlinearities in two individual periodically poled lithium ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Cascade: Channel-Aware Structured Cosparse Audio Declipper [PDF]

2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
This work features a new algorithm, CASCADE, which leverages a structured cosparse prior across channels to address the multichannel audio declipping problem. CASCADE technique outperforms the state-of-the-art method A-SPADE applied on each channel separately in all tested settings, while retaining similar runtime.

All-optical pulse retiming based on quadratic cascading in a periodically poled lithium niobate waveguide [PDF]

, 2010
We demonstrate an all-optical technique for the elimination of timing jitter in short pulse transmission systems. The technique relies on pulse pre-shaping followed by optical switching in a periodically poled lithium niobate waveguide via cascaded ...
