Lower Hybrid Current Drive in High Aspect Ratio Tokamaks

Hoang-Trang Lam, Joan Decker, Xiaoxia Bai

A multi-machine study has been carried out to investigate the impact of a strongly bounded wave propagation domain on the Lower Hybrid current drive, a condition which occurs principally in high aspect ratio tokamaks. In this regime, the condition of kinet ...

Balance Control Strategies during Standing in a Locked-Ankle Passive Exoskeleton

Hannes Bleuler, Mohamed Bouri, Jemina Fasola, Tristan Hubert Vouga, Romain Pierre François Baud

This paper investigates sensorimotor adaptation strategies of sagittal postural control in healthy subjects under kinematic constraints. A passive exoskeleton named CAPTUR, with locked ankle joints and legs motion restrained to the sagittal plane is used t ...

Fourier light scattering model for treating textures deeper than the wavelength

Christophe Ballif, Franz-Josef Haug, Matthias Wolfgang Bräuninger

We apply a Fourier-scattering model to describe light scattering in solar cells with textured surfaces. For the size and inclination angle of typical micro-textures, scattering may occur into large angles. This makes the model prone to paraxial errors. We ...

Multi-segment analysis of spinal kinematics during sit-to-stand in patients with chronic low back pain

Julien Favre, Thomas Legrand, Guillaume Christe

While alterations in spinal kinematics have been frequently reported in patients with chronic low back pain (CLBP), a better characterization of the kinematics during functional activities is needed to improve our understanding and therapeutic solutions fo ...

Physics of Polariton Condensates in GaN-based Planar Microcavities

Jacques Levrat

Since its prediction in 1996 by Imamoğlu and coworkers, the use of a non-equilibrium polariton condensate to produce an intense coherent light source referred to as a polariton laser has attracted a lot of interest in the whole physics community as it ...

System size effects on gyrokinetic turbulence

Laurent Villard, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Xavier Lapillonne

The scaling of turbulence-driven heat transport with system size in magnetically confined plasmas is reexamined using first-principles based numerical simulations. Two very different numerical methods are applied to this problem, in order to resolve a long ...
