Channelization cascade in landscape evolution [PDF]
Proceedings of the National Academy of Sciences, 2020 The hierarchy of channel networks in landscapes displays features that are characteristic of nonequilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equations coupling landscape evolution dynamics with a specific catchment area equation. By means of a

Secure Cascade Channel Synthesis [PDF]
IEEE Transactions on Information Theory, 2013 We consider the problem of generating correlated random variables in a distributed fashion, where communication is constrained to a cascade network. The first node in the cascade observes an i.i.d. sequence $X^n$ locally before initiating communication along the cascade. All nodes share bits of common randomness that are independent of $X^n$.

Hypothesis testing over cascade channels [PDF]
2017 IEEE Information Theory Workshop (ITW), 2017 Binary hypothesis testing over single and parallel cascade channels is considered where sensors communicate with dedicated relays, and these relays with a single final receiver. All relays as well as the final receiver decide on the binary hypothesis governing the joint probability distribution of the observations at the sensors, relays, and final ...

On binary channels and their cascades [PDF]
IEEE Transactions on Information Theory, 1955 A detailed analysis of the general binary channel is given, with special reference to capacity (both separately and in cascade), input and output symbol distributions, and probability of error. The infinite number of binary channels with the same capacity lie on double-branched equicapacity lines.

The Role of TRP Channels in the Metastatic Cascade [PDF]
Pharmaceuticals, 2018 A dysregulated cellular Ca2+ homeostasis is involved in multiple pathologies including cancer. Changes in Ca2+ signaling caused by altered fluxes through ion channels and transporters (the transportome) are involved in all steps of the metastatic cascade. Cancer cells thereby “re-program” and “misuse” the cellular transportome to regulate proliferation,

Min-Entropy Leakage of Channels in Cascade [PDF]
, 2012 Theories of quantitative information flow offer an attractive framework for analyzing confidentiality in practical systems, which often cannot avoid "small" leaks of confidential information. Recently there has been growing interest in the theory of min-entropy leakage, which measures uncertainty based on a random variable's vulnerability to being ...

Path Loss Model for 3.5 GHz and 5.6 GHz Bands in Cascaded Tunnel Environments
Sensors, 2022 An important and typical scenario of radio propagation in a railway or subway tunnel environment is the cascaded straight and curved tunnel. In this paper, we propose a joint path loss model for cascaded tunnels at 3.5 GHz and 5.6 GHz frequency bands. By

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.
