Common electrophysiological signatures of relative magnitude in both space and time Open
Duration processing can be indexed by the amplitude of two electrophysiological potentials, the contingent negative variation (CNV) and the late positive component (LPC). When a currently elapsing event becomes longer than that of a memori…

X-ray simulations with gVirtualXray in medicine and life sciences Open
gVirtualXray (gVXR) is a programming interface framework to simulate realistic X-ray projections in realtime on graphics processing units (GPUs). It solves the Beer-Lambert law (attenuation law) using a deterministic X-ray simulation algor…

Why is there an error negativity on correct trials? A reappraisal Open
In healthy subjects, the Error Negativity (Ne) was initially reported on errors and on partial errors, only. Later on, application of the Laplacian transformation to EEG data unmasked a Ne-like wave (Nc) that shares a main generator with t…

Simulation of X-ray projections on GPU: Benchmarking gVirtualXray with clinically realistic phantoms Open
When scattering can be ignored, accurate images that would take days using MC can be generated in milliseconds with gVirtualXray. This speed of execution enables the use of repetitive simulations with varying parameters, e.g. to generate t…

Visualization for epidemiological modelling: challenges, solutions, reflections and recommendations Open
We report on an ongoing collaboration between epidemiological modellers and visualization researchers by documenting and reflecting upon knowledge constructs—a series of ideas, approaches and methods taken from existing visualization resea…

On the Comparison Between the Nc/CRN and the Ne/ERN Open
After the Error Negativity (Ne or ERN) has been described on full-blown errors and on partial error, a smaller Error Negativity-like wave (CRN or Nc) has also been evidenced on correct trials, first in patients with schizophrenia and, late…

Interactive teaching environment for diagnostic radiography with real-time X-ray simulation and patient positioning Open
Purpose Traditional undergraduate radiographer training mixes academic lectures and clinical practice. Our goal is to bridge the current disconnection between theory and practice in a safe environment, avoiding the risk of radiation for bo…

Action monitoring fails when motor execution is too fast: no time for correction Open
Reducing the duration of motor execution processes also reduces the time available to detect and correct an incorrect activation.Therefore, we provide evidence that performance can be impaired, not only by decreasing the efficiency of the …

Action monitoring fails when motor execution is too fast: no time for correction Open
A recent information processing model of two-choice RT situations (Servant et al., 2015), suggests that conditions which reduce the duration of peripheral motor processes, should also reduce the efficiency of the action monitoring system, …

Deciphering the nature of the joint Simon effect through electromyographic analyses Open
This study aimed to apply electromyographic techniques and distributional analyses to test whether an increase in the strength of stimulus-response mapping could explain the mechanisms underlying the joint Simon effect. Within a single pro…
