Sensor system

Simon Nessim Henein, Charles Baur, Hubert Pierre-Marie Benoît Schneegans, Thomas Jean Julien Fussinger, Lisa Anaïs Jeanne Bonnefoy

Sensor system (1) comprising a frame (306) supporting a force-sensing tip (310) arranged to generate a signal based upon a force applied by said force-sensing tip (310) to a material to be tested,characterised in that said system (1) further comprises:- an ...

Manipulating Topological Domain Boundaries in the Single-Layer Quantum Spin Hall Insulator 1T '-WSe2

Oleg Yazyev, Yixing Chen, Michele Pizzochero, Artem Pulkin, Feng Wang

We report the creation and manipulation of structural phase boundaries in the single-layer quantum spin Hall insulator 1T'-WSe2 by means of scanning tunneling microscope tip pulses. We observe the formation of one-dimensional interfaces between topological ...

Suprathermal electron driven fishbone instability in the TCV tokamak

Stefano Coda, Jonathan Graves, Laurie Porte, Antoine Pierre Emmanuel Alexis Merle, Joan Decker, Dahye Choi, Arsène Stéphane Tema Biwole

Observations of fishbone oscillations driven by energetic electrons have been reported in several tokamaks, but experimental evidence of the interaction between electrons and the mode has remained limited. In the TCV tokamak, a state-of-the-art multi-chann ...

Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking

Tomás Alfredo Trewhela Palacios, Carmela Lardo

Context. Extended main sequence turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the main sequence turn-off is broader than can be explained by photome ...

On the Dynamics of Magnetic Swimmers in Stokes Flow

Pauline Marie Rüegg-Reymond

In the past decade, the engineering community has conceived, manufactured and tested micro-swimmers, i.e. microscopic devices which can be steered in their intended environment. Foreseen applications range from microsurgery and targeted drug delivery to en ...

Optimized up-down asymmetry to drive fast intrinsic rotation in tokamaks

Justin Richard Ball

Breaking the up-down symmetry of the tokamak poloidal cross-section can significantly increase the spontaneous rotation due to turbulent momentum transport. In this work, we optimize the shape of flux surfaces with both tilted elongation and tilted triangu ...

Optimal visuo-vestibular integration for self-motion perception in patients with unilateral vestibular loss

Olaf Blanke, Mariia Kaliuzhna, Steven Gale

Unilateral vestibular loss (UVL) is accompanied by deficits in processing of visual and vestibular self-motion cues. The present study examined whether multisensory integration of these two types of information is, nevertheless, intact in such patients. Pa ...

Differential effects of vestibular processing on orienting exogenous and endogenous covert visual attention

Olaf Blanke, Mariia Kaliuzhna, Andrea Serino, Steve Michel Berger

Recent research highlights the overwhelming role of vestibular information for higher order cognition. Central to body perception, vestibular cues provide information about self-location in space, self-motion versus object motion, and modulate the percepti ...

Bayesian adaptation of chaos representations using variational inference and sampling on geodesics

Panagiotis Tsilifis

A novel approach is presented for constructing polynomial chaos representations of scalar quantities of interest (QoI) that extends previously developed methods for adaptation in Homogeneous Chaos spaces. In this work, we develop a Bayesian formulation of ...
