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 ...

Info-Clustering: A Mathematical Theory for Data Clustering

, 2016
We formulate an info-clustering paradigm based on a multivariate information measure, called multivariate mutual information, that naturally extends Shannon's mutual information between two random variables to the multivariate case involving more than ...

TAS-Based Incremental Hybrid Decode–Amplify–Forward Relaying for Physical Layer Security Enhancement [PDF]

, 2017
In this paper, a transmit antenna selection (TAS)- based incremental hybrid decode-amplify-forward (IHDAF) scheme is proposed to enhance physical layer security in cooperative relay networks.

Maximum Secrecy Throughput Analysis of Practical RIS-Aided mmWave Systems Over Unified FTR/IFTR Fading Channels

IEEE Transactions on Wireless Communications
In this paper, we consider a millimeter-wave (mmWave) wiretap scenario where a multiple-antenna base station (Alice) communicates with a legitimate user (Bob) via a reconfigurable intelligent surface (RIS) amid multiple colluding eavesdroppers (Eves ...

Plant Variety Registration in Transition: Opportunities for Innovation and Reform in The European Union Enregistrement des variétés végétales en transition : opportunités d’innovation et de réforme dans l’Union européenne Die Registrierung von Pflanzensorten im Wandel: Chancen für Innovation und Neugestaltung in der Europäischen Union

EuroChoices, EarlyView.
Summary Modernising the European Union’s plant variety registration system is critical to enabling the development and adoption of sustainable, climate‐resilient varieties aligned with the EU Farm‐to‐Fork Strategy. However, the current system is outdated and under increasing pressure. While legislative reform is underway, key points of divergence among

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

Conservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Engineering exosomes for Alzheimer's disease: Multi‐target therapeutic strategies from pathogenesis to clinical translation

Clinical and Translational Medicine, Volume 15, Issue 12, December 2025.
Exosomes, modified through multidimensional approaches including physical, chemical and genetic means, and equipped with brain‐targeted peptides and therapeutic agents, are capable of crossing the blood‒brain barrier for precise delivery. They can simultaneously remove amyloid‐beta plaques and neurofibrillary tangle, inhibit neuroinflammation, and pave

A Touch of Evil: High-Assurance Cryptographic Hardware from Untrusted Components [PDF]

, 2017
The semiconductor industry is fully globalized and integrated circuits (ICs) are commonly defined, designed and fabricated in different premises across the world. This reduces production costs, but also exposes ICs to supply chain attacks, where insiders

Physical-Layer Security in Mixed UOWC-RF Networks With Energy Harvesting Relay Against Multiple Eavesdroppers

IEEE Open Journal of the Communications Society
In this study, physical layer security (PLS) in a dual-hop underwater optical wireless communication (UOWC)-radio frequency (RF) network under the intruding attempts of multiple eavesdroppers via RF links is considered. An intermediate decode-and-forward
