Camera PPG waveforms at the forehead
A. C. den Brinker, H. H. Der Sarkissian, J. H. Wülbern +5
In order to obtain insights into the feasibility of replacing ECG-guided triggering in magnetic resonance imaging (MRI) by a system based on video photoplethysmography (PPG), PPG a…
Evidence for a Quantum Hall Insulator in an InGaAs/InP Heterostructure
D. T. N. de Lang, L. A. Ponomarenko, A. de Visser +3
We study the quantum critical behavior of the plateau-insulator (PI) transition in a low mobility InGaAs/InP heterostructure. By reversing the direction of the magnetic field (B) w…
Critical behaviour of thermopower and conductivity at the metal-insulator transition in high-mobility Si-MOSFETs
R. Fletcher, V. M. Pudalov, A. D. B. Radcliffe +1
This paper reports thermopower and conductivity measurements through the metal-insulator transition for 2-dimensional electron gases in high mobility Si-MOSFETs. At low temperature…
