Unsupervised and efficient learning in sparsely activated convolutional spiking neural networks enabled by voltage-dependent synaptic plasticity

Gaspard Goupy, Alexandre Juneau-Fecteau, Nikhil Garg, Ismael Balafrej, F. Alibart, Luc Frechette, Dominique Drouin, Yann Beilliard

Spiking neural networks (SNNs) are gaining attention due to their energy-efficient computing ability, making them relevant for implementation on low-power neuromorphic hardware. Their biological plausibility has permitted them to benefit from unsupervised learning with bio-inspired plasticity rules...

Highly-sensitive SERS detection of tetracycline: Sub-enhancement brought by light scattering of nano-diamond

Jingxuan Pei, Zhenfei Tian, Xiang Yu, Shuting Zhang, Shiqing Ma, Yibo Sun, Rabah Boukherroub

Antibiotic residues in wastewater cause a serious threat to aquatic environment and human safety. Therefore, the development of robust strategies for detecting antibiotic residues becomes critical. In this work, a surface-enhanced Raman scattering (SERS) substrate, consisting of gold nanoparticles/...

Space-time Modulation in a Piezoelectric Phononic Crystal: Experimental Study in Sub-sonic and Sonic Regimes

Sarah Tessier Brothelande, Charles Croenne, Florian Allein, Jerome Vasseur, Bertrand Dubus

We experimentally study acoustic wave propagation in a spatio-temporally modulated system for different modulation speeds, up to the sonic regime when the modulation speed is similar to the wave propagation speed. The system under study is a piezoelectric phononic crystal whose electrical boundary...

Spin Seebeck effect and thermal properties of zigzag graphene nanoribbons with edge magnetism

Jing Li, Yann-Michel Niquet, Christophe Delerue

Zigzag graphene nanoribbons (GNRs), demonstrating edge magnetism, are fascinating materials for electronic and spintronic applications. In this paper, we investigate with explicit consideration of electron-phonon scattering the Seebeck effect and thermal conductivity at various carrier densities in...

Signal Denoising and Detection for Uplink in LoRa Networks based on Bayesian-optimized Deep Neural Networks

Angesom Ataklity Tesfay, Sofiane Kharbech, Eric Pierre Simon, Laurent Clavier

Long-range and low-power communications are suitable technologies for the Internet of things networks. The long-range implies a very low signal-to-noise ratio at the receiver. In addition, low power consumption requires reduced signaling, hence the use of less complex protocols, such as ALOHA, so...

Effect of electronic stopping in molecular dynamics simulations of collision cascades in gallium arsenide

Johannes L. Teunissen, Thomas Jarrin, Nicolas Richard, Natalia E. Koval, Daniel Muñoz Santiburcio, Jorge Kohanoff, Emilio Artacho, Fabrizio Cleri, Fabiana da Pieve

Understanding the generation and evolution of defects induced in matter by ion irradiation is of fundamental importance to estimate the degradation of functional properties of materials. Computational approaches used in different communities, from space radiation effects to nuclear energy...

Fabrication of silicon nitride membrane nanoelectromechanical resonator

Hao Xu, Srisaran Venkatachalam, Christophe Boyaval, Pascal Tilmant, Francois Vaurette, Yves Deblock, Didier Theron, Xin Zhou

In this work, we present details of the nanofabrication process for achieving a silicon nitride nanoelectromechanical resonator, consisting of a membrane covered with a thin aluminium layer capacitively coupled to a suspended top gate. Critical nanofabrication steps have been discussed, including...

Topological vortex mode for flexural waves in pillared plates

Zhihui Wen, Julio Andrés Iglesias Martínez, Yabin Jin, Yan Li, Bahram Djafari-Rouhani, Daniel Torrent, Jean-Louis Raynaud, Abdelkrim Khelif

Localized topological modes with high robustness to various perturbations are receiving increasing attention. Recently, zero-order topological vortex modes have been designed in phononic structures, in analogy with zero-energy fermionic states modulated by Jackiw-Rossi binding mechanism. Such...
