Artificial Neural Network Driven Computational Modeling of Naegleria fowleri Epidemics Using Variational Optimization

Advanced Physics Research, EarlyView.
ABSTRACT This study presents a mathematical framework to analyze the transmission dynamics of an amoeba‐induced central nervous system infection. The population is divided into compartments including susceptible, exposed, infected, quarantined, hospitalized, recovered, protected, and deceased.

Wiretap channel II with a noisy main channel

2015 IEEE International Symposium on Information Theory (ISIT), 2015
In this paper, a wiretap channel where the transmitter and receiver communicate through a discrete memoryless channel, and the eavesdropper (Eve) has perfect access to a fixed fraction of transmitted symbols (of its choosing) is considered. An outer bound for the rate-equivocation region of the channel, for all such fractions, is derived. An achievable

Generalizing Multiple Access Wiretap and Wiretap II Channel Models: Achievable Rates and Cost of Strong Secrecy

IEEE Transactions on Information Theory, 2019
In this paper, new two-user multiple access wiretap channel models are studied. First, the multiple access wiretap channel II with a discrete memoryless main channel under different wiretapping scenarios is introduced. The wiretapper, as in the classical

Strongly Secure Communications Over the Two-Way Wiretap Channel

IEEE Transactions on Information Forensics and Security, 2011
—We consider the problem of secure communications over the two-way wiretap channel under a strong secrecy criterion. We improve existing results by developing an achievable region based on strategies that exploit both the interference at the eaves ...

The Wiretap Channel with a Cache

2018 IEEE International Symposium on Information Theory (ISIT), 2018
We consider the wiretap channel when a (secure) cache memory is added to the legitimate receiver. With the goal of utilizing coded caching for improving secrecy, during the cache placement phase, the receiver caches a function of the files, and the secret key shared with the transmitter subject to the memory constraint. The signals transmitted to serve

Achieving Secrecy Capacity of the Wiretap Channel and Broadcast Channel With a Confidential Component

IEEE Transactions on Information Theory, 2017
The wiretap channel model of Wyner is one of the first communication models with both reliability and security constraints. Capacity-achieving schemes for various models of the wiretap channel have received considerable attention in recent literature. In

A New Wiretap Channel Model and Its Strong Secrecy Capacity

IEEE Transactions on Information Theory, 2018
In this paper, a new wiretap channel model is proposed, where the legitimate transmitter and receiver communicate over a discrete memoryless channel. The wiretapper has perfect access to a fixed-length subset of the transmitted code word symbols of her ...
