A Wireless System with Stimulation and Recording Capabilities for Interfacing Peripheral Nerves in Rodents

Stéphanie Lacour, Amélie Anne Guex, Frédéric Pierre Gérald Michoud, Qiuting Huang, Noé Brun

Considerable progress has been made in the last decade in implantable bioelectronic neurosystems. Yet most neural implants are used in acute and tethered experimental conditions. Here, we present a preliminary prototype of a multichannel system for simulta ...

Distributed wireless video caching placement for dynamic adaptive streaming

Pascal Frossard, Chenglin Li

Caching at edge servers can smooth the temporal traffic variability and reduce the service load of base stations in wireless streaming. However, the assignment of the cached content for possibly multiple versions of different video sequences is still a cha ...

Three-dimensional magnetohydrodynamic equilibrium of quiescent H-modes in tokamak systems

Olivier Sauter, Basil Duval, Jonathan Graves, Wilfred Anthony Cooper, Trach-Minh Tran, Jonathan Marc Philippe Faustin, Hamish William Patten, Samuel Lanthaler, Madhusudan Raghunathan, Andreas Kleiner

Three dimensional free boundary magnetohydrodynamic equilibria that recover saturated ideal kink/peeling structures are obtained numerically. Simulations that model the JET tokamak at fixed = 1.7% with a large edge bootstrap current that flattens t ...
