Effects of initial eye position on saccades evoked by microstimulation in the primate superior colliculus: implications for models of the SC read-out process

open access: yesFrontiers in Integrative Neuroscience, 2011
The motor layers of the superior colliculus (SC) are thought to specify saccade amplitude and direction, independent of initial eye position. However, recent evidence suggests that eye position can modulate the level of activity of SC motor neurons.

Different roles of alpha and beta band oscillations in sensorimotor gating

open access: yesFrontiers in Human Neuroscience, 2014
Alpha (8-12Hz) and beta band (18-30Hz) oscillations have been implicated in sensory anticipation and motor preparation. Here, using magneto-encephalography, we tested whether they have distinct functional roles in a saccade task that induces a remapping ...

De la notion au référentiel international de politique publique. Le savant, l’expert et le politique dans la construction du vieillissement actif

open access: yesRecherches Sociologiques et Anthropologiques, 2013
The goal of this article is to show how, from a simple concept, “active ageing” was gradually transformed into an international frame of reference in public policies on the subject of ageing.

Reduced Reference Frame Transformation Assessment in Unbalanced Three-Phase Four-Wire Systems

open access: yesIEEE Access, 2023
Three-phase four-wire systems require a reference frame similar to that used in 3-phase 3-wire system configurations that allow them to be easily analysed, modelled and controlled.

A Unified Global Reference Frame of Vertical Crustal Movements by Satellite Laser Ranging

open access: yesSensors, 2016
Crustal movement is one of the main factors influencing the change of the Earth system, especially in its vertical direction, which affects people’s daily life through the frequent occurrence of earthquakes, geological disasters, and so on.

Blazars define a stable celestial reference frame

open access: yesAstronomy & Astrophysics
Context. Recent work has shown that optical-radio position offsets and radio position variability are inversely correlated with the optical photometric variability of active galactic nuclei (AGN).

The Two-Wrongs model explains perception-action dissociations for illusions driven by distortions of the egocentric reference frame

open access: yesFrontiers in Human Neuroscience, 2015
Several studies have demonstrated a dissociation of the effects of illusion on perception and action, with perception generally reported to be susceptible to illusions, while actions are seemingly immune.

Adaptive training‐feedback scheme for FDD in massive MIMO systems

open access: yesIET Communications, 2023
Accurate acquisition of channel state information (CSI) is crucial but difficult in frequency division duplex (FDD) massive multiple‐input multiple‐output (MIMO) systems.

Concept of spatial coordinate systems, their defining and implementation as a precondition in geospatial applications [PDF]

open access: yesGlasnik Srpskog Geografskog Društva, 2015
There are many users of spatial information, and quite large interest about the nature and genesis of such information. Different users found spatial information in the form of maps, plans or alphanumerical tables. Recently, there are more often
