Frames of Reference [PDF]

open access: yesJournal of Applied Social Science, 2016
Unforeseen obstacles and inefficiencies may arise when medical organizations seek to implement protocols that rely upon cooperation and coordination by clinical practitioners from multiple disciplines, departments, and professional orientations. In this reflection, we discuss some ways in which sociological concepts may be useful in forestalling and ...

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.

A computational model of the referential semantics of projective prepositions [PDF]

open access: yes, 2006
In this paper we present a framework for interpreting locative expressions containing the prepositions in front of and behind. These prepositions have different semantics in the viewer-centred and intrinsic frames of reference (Vandeloise, 1991).

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 ...

Error Correction of Quantum Reference Frame Information

open access: yesPRX Quantum, 2021
The existence of quantum error-correcting codes is one of the most counterintuitive and potentially technologically important discoveries of quantum-information theory.

A two-point boundary value problem on a Lorentz manifold arising in A. Poltorak's concept of reference frame [PDF]

open access: yes, 2006
In A. Poltorak's concept, the reference frame in General Relativity is a certain manifold equipped with a connection. The question under consideration here is whether it is possible to join two events in the space-time by a time-like geodesic if they are

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.

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.

Nutation and Reference Frame [PDF]

open access: yesHighlights of Astronomy, 1995
The reference frames are of fundamental importance in all kinds of the precession and nutation studies involving the theory, the coordinate transformation and the observations. The aim of this paper is to review all the frames used in such studies and to lead to a better consistency between them in order that theory and reductions of observations be ...

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.
