Secure Transmission in NOMA Systems: An Efficient Resource Allocation Strategy Using Deep Learning

Miled Alam, Abdul Karim Gizzini, Laurent Clavier

Deep learning (DL) algorithms have been widely integrated in various aspects of wireless communications research. In this paper, we investigate, in an Internet of Things context, the secrecy energy-efficiency (SEE) of a multi-user downlink non-orthogonal multiple access (NOMA) system in the…

In situ growth of N-doped carbon nanotubes from the products of graphitic carbon nitride etching by nickel nanoparticles

Mariusz Pietrowski, Emilia Alwin, Michał Zieliński, Sabine Szunerits, Agata Suchora, Robert Wojcieszak

The in situ growth of N-doped multi-walled carbon nanotubes (N-MWCNTs) from the products of graphitic carbon nitride (g-C$_3$N$_4$) etching by Ni nanoparticles in a hydrogen atmosphere has been confirmed for the first time. During the etching process of g-C$_3$N$_4$, the building blocks, notably…

Influence of critical micelle concentration of choline-based long chain fatty acid soaps on their antibacterial activity against Methicillin resistant Staphylococcus aureus

Helena Arellano, Tomasz Swebocki, Clémence Le Coeur, Sylvain Prévost, Marwan Abdallah, Véronique Nardello-Rataj, Anne-Laure Fameau

Hypothesis: Antimicrobial resistance (AMR) is a pressing global health concern. ESKAPEE pathogens, such as Methicillin-resistant Staphylococcus aureus (MRSA) are notable of concern in healthcare settings due to their resistance to critical antibiotics. To combat AMR, the development of alternatives…

Investigation of the motif activity of transcription regulators in pancreatic β-like cell subpopulations differentiated from human induced pluripotent stem cells

Eric Leclerc, Mikhail Pachkov, Lisa Morisseau, Fumiya Tokito, Cecile Legallais, Rachid Jellali, Masaki Nishikawa, Amar Abderrahmani, Yasuyuki Sakai

Pancreatic β-cells are composed of different subtypes that play a key role in the control of insulin secretion and thereby control glucose homeostasis. In vitro differentiation of human induced pluripotent stem cells (hiPSCs) into 3D spheroids leads to the generation of β-cell subtypes and thus to…

Optimizing Connectivity: DVB-RCS2 Uplink to GEO Satellites via Optical Wireless Communication

Meryem Romaissa Djellouli, Sid Ahmed Chouakri, Abdelkrim Ghaz, Abdelmalik Taleb-Ahmed

This research focuses on the integration of an opto-satellite system based on Free Space Optical Communication (OWC) within DVB-RCS2 chains, implementing 16-QAM modulation techniques and Optical Time Division Wavelength Multiplexing (OTDMWDM). A co-simulation framework combining the MATLAB and…

Autonomous radar interference detection and mitigation using neural network and signal decomposition

Dayat Kurniawan, Budiman Putra Asmaur Rohman, Ratna Indrawijaya, Chaeriah Bin Ali Wael, Suyoto Suyoto, Purwoko Adhi, Iman Firmansyah

Autonomous radar interference is a challenging problem in autonomous vehicle systems. Interference signals can decrease the signal-to-interference-noise ratio (SINR), and this condition decreases the performance detection of autonomous radar. This paper exploits a neural network and signal…

Immunity to Backscattering of Bulk Waves in Topological Acoustic Superlattices

P A Deymier, Jérome O Vasseur, K. Runge, A. Khanikaev, A. Alù

We herein investigate the scattering of orthogonal counterpropagating waves and one-way propagating bulk waves in discrete acoustic superlattices subjected to a scattering potential applied to one of the superlattice unit cells. We demonstrate theoretically that the orthogonality of…

500 GHz operational bandwidth MUTC-photodiodes with milliwatt terahertz output power levels

Ezgi Abacıoğlu, Marcel Grzeslo, Tom Neerfeld, Abdu Subahan Mohammed, J L F Estévez, Guillaume Ducournau, Andreas Stöhr

We present waveguide-integrated 1.55 μm InP-based modified uni-travelling-carrier photodiodes (MUTC-PDs) featuring coplanar waveguide outputs. The fabricated photodiodes yield an operational bandwidth of 500 GHz and milliwatt output power levels in the lower THz domain.
