On effective secrecy throughput of underlay spectrum sharing α - μ/ Málaga hybrid model under interference-and-transmit power constraints [PDF]

, 2023
The underlay cognitive radio-based hybrid radio frequency/free-space optical (RF/FSO) systems have emerged as a promising technology due to their ability to eliminate spectrum scarcity and spectrum under-utilization problems.

Physical Layer Security in Uplink NOMA Multi-Antenna Systems With Randomly Distributed Eavesdroppers

IEEE Access, 2019
The physical layer security of uplink non-orthogonal multiple access (NOMA) is analyzed. A stochastic geometry approach is applied to analyze the coverage probability and effective secrecy throughput (EST) of the kth NOMA user, where a fixed or an ...

Physical Layer Security in Cognitive Untrusted Relay Networks

IEEE Access, 2018
In this paper, we consider the secure communications in a cognitive untrusted relay network, where the secondary source intends to communicate with a secondary destination through an untrusted relay in the presence of the direct source-destination link ...

A pipeline for high throughput detection and mapping of SNPs from EST databases [PDF]

, 2010
Single nucleotide polymorphisms (SNPs) represent the most abundant type of genetic variation that can be used as molecular markers. The SNPs that are hidden in sequence databases can be unlocked using bioinformatic tools.

Secrecy Throughput of ANECE Assisted Transmission of Information in Finite Blocklength [PDF]

, 2022
Anti-eavesdropping channel estimation (ANECE) among two or more cooperative full-duplex radio devices allows these devices to obtain consistent estimates of their receive channel state information (CSI) with respect to each other but at the same time ...

Physical Layer Security in an Untrusted Energy Harvesting Relay Network

IEEE Access, 2019
The security performance in an amplify-and-forward dual-hop untrusted relay network is considered. It is assumed that the source and multiple destinations are equipped with multiple antennas, and the information transmission is aided by a single-antenna ...

Future of edge AI in biodiversity monitoring

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecological decisions are slowed by the gap between collecting and analysing biodiversity information. Edge computing moves data processing closer to the sensor, with edge artificial intelligence (AI) using AI models for data processing and selective data transfer.

Secrecy Throughput Maximization for Full-Duplex Wireless Powered IoT Networks under Fairness Constraints [PDF]

, 2019
In this paper, we study the secrecy throughput of a full-duplex wireless powered communication network (WPCN) for internet of things (IoT). The WPCN consists of a full-duplex multi-antenna base station (BS) and a number of sensor nodes.

Unravelling polyphenol skin permeation: A comparative study using full‐thickness 3D in vitro and ex vivo human skin models

International Journal of Cosmetic Science, EarlyView.
This study demonstrates that full‐thickness 3D in vitro skin models reliably assess the permeation of cosmetic polyphenols, revealing compound‐specific transport profiles and bridging the gap between conventional cell models and ex vivo human skin, while offering an ethical and robust alternative for dermal absorption screening. Abstract The evaluation
