On The Capacity Of A Cascade Of Channels
Proceedings. 1991 IEEE International Symposium on Information Theory, 1993Summary: A class of information-theoretic problems is introduced that deal with systems in which information is transmitted through a series of noisy channels, with limited or no processing between channels. Some basic questions that arise in such systems are examined in detail.

Cluster Channeling in Cascade Reactions
The Journal of Physical Chemistry B, 2021Enzymatic cascade reactions, where a substrate is converted into a product in several steps, play a critical role in many biological systems. The enzymes in such reactions are often clustered inside intracellular compartments. To understand the effect of localization, we develop a theory for cascade reactions converting substrates into intermediates ...

Cascading blockages in channel bundles
Physical Review E, 2015Flow in channel networks may involve a redistribution of flux following the blockage or failure of an individual link. Here we consider a simplified model consisting of N(c) parallel channels conveying a particulate flux. Particles enter these channels according to a homogeneous Poisson process and an individual channel blocks if more than N particles ...

Cascade channels with infinite memory
2016 IEEE International Symposium on Information Theory (ISIT), 2016Two theorems are proved for a cascade channel with two components, one theorem regarding input memory and the other regarding output memory. First, we show that if both components are asymptotically input-memoryless, then the cascade channel is asymptotically input-memoryless as well.

Substrate channelling as an approach to cascade reactions
Nature Chemistry, 2016Millions of years of evolution have produced biological systems capable of efficient one-pot multi-step catalysis. The underlying mechanisms that facilitate these reaction processes are increasingly providing inspiration in synthetic chemistry. Substrate channelling, where intermediates between enzymatic steps are not in equilibrium with the bulk ...

Cascaded Double Beaulieu-Xie Fading Channels
IEEE Communications Letters, 2020In this letter, a mathematical characterization for the cascaded double Beaulieu-Xie (BX) fading model is presented. Exact and new expressions are determined for the probability density function (PDF) and for the cumulative distribution function (CDF) of the random variable that models the envelope of the cascaded double BX fading, and for the PDF and ...

Mechanisms and Effects of Substrate Channelling in Enzymatic Cascades
2021Substrate or metabolite channelling is a transfer of intermediates produced by one enzyme to the sequential enzyme of a reaction cascade or metabolic pathway, without releasing them entirely into bulk. Despite an enormous effort and more than three decades of research, substrate channelling remains the subject of continuing debates and active ...

Cascaded Fluctuating Two-Ray Fading Channels
IEEE Communications Letters, 2019In this letter, we derive the exact probability density function (PDF), cumulative distribution function (CDF), and generalized moment generating function of a product of $N$ independent fluctuating two-ray (FTR) random variables. Capitalizing on the derived expressions, new expressions for the PDF and CDF of the FTR fading model, i.e., $N=1$

On the Performance of Cascaded Generalized K Fading Channels
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009A novel distribution referred to as N*generalized κ, constructed as the product of N statistically independent, but not necessarily identically distributed, generalized κ random variables (RVs) is introduced. Statistical characterization of the proposed distribution is carried out via the derivation of closed-form expressions for its moment generating,

Channel Prediction with Cascade AR Modeling
Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06), 2006Cascade autoregressive (AR) model with three parameters for any channel prediction order p is investigated. Although higher order AR model is better to get more precise future channel prediction profile, as the order of channel prediction goes higher, the number of channel prediction parameters we have to know is increased.
