Any neuron can perform linearly non-separable computations

Romain Cazé

Multiple studies have shown how dendrites enable some neurons to perform linearly non-separable computations. These works focus on cells with an extended dendritic arbor where voltage can vary independently, turning dendritic branches into local non-linear subunits. However, these studies leave a…

MEMS High Temperature Gradient Sensor for Skin-Friction Measurements in Highly Turbulent Flows

Cécile Ghouila-Houri, Abdelkrim Talbi, Romain Viard, Quentin Gallas, Eric Garnier, Pascal Molton, Jerome Delva, Alain Merlen, Philippe Pernod

This paper presents and discusses the results obtained with a MEMS (Micro-Electro-Mechanical System) high temperature gradient sensor for time-averaged and fluctuating skin-friction measurements in highly turbulent flows. Designed as a robust wall-mounted suspended hot-wire structure, the micro-…

Low impedance and highly transparent microelectrode arrays (MEA) for in vitro neuron electrical activity probing

Anna Susloparova, Sophie Halliez, Séverine Begard, Morvane Colin, Luc Buée, Sébastien Pecqueur, F. Alibart, V. Thomy, S. Arscott, Emiliano Pallecchi, Yannick Coffinier

In this study, we present the microfabrication and characterization of a transparent microelectrode array (MEA) system based on PEDOT:PSS for electrophysiology. The influence of the PEDOT:PSS electrode dimensions on the impedance was investigated and the stability over time under physiological…

AIDX: Adaptive Inference Scheme to Mitigate State-Drift in Memristive VMM Accelerators

Tony Liu, Amirali Amirsoleimani, F. Alibart, Serge Ecoffey, Dominique Drouin, Roman Genov

An adaptive inference method for crossbar (AIDX) is presented based on an optimization scheme for adjusting the duration and amplitude of input voltage pulses. AIDX minimizes the long-term effects of memristance drift on artificial neural network accuracy. The sub-threshold behavior of memristor…

High temperature gradient micro-sensors for skin-friction measurement in flow control applications

Cécile Ghouila-Houri, Manon Benedito, Eric Garnier, Abdelkrim Talbi, Aurélien Mazzamurro, Romain Viard, Alain Merlen, Philippe Pernod, Thomas Arnoult, Quentin Gallas

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were designed and developed for flow separation control. Based on thermal principle, the transducers measure the amplitude and the sign of skin friction, making them particularly useful for flow separation detection. A…

Carbon–nitrogen bond formation using modified graphene oxide derivatives decorated with copper complexes and nanoparticles

M. Mirza-Aghayan, M. Saeedi, Rabah Boukherroub

Several catalytic reactions such as Ullmann, Chan–Lam, Huisgen 1,3-dipolar cycloaddition, [2 + 3] cycloaddition, condensation, and coupling reactions under suitable conditions have been used for the synthesis of fundamental structures containing a carbon–nitrogen (C–N) bond. Graphene oxide (GO) and…
