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

Adaptive training‐feedback scheme for FDD in massive MIMO systems
Accurate acquisition of channel state information (CSI) is crucial but difficult in frequency division duplex (FDD) massive multiple‐input multiple‐output (MIMO) systems.

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

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.

Nutation and Reference Frame [PDF]
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 ...

Should there be a spin-rotation coupling for a Dirac particle? [PDF]
It was argued by Mashhoon that a spin-rotation coupling term should add to the Hamiltonian operator in a rotating frame, as compared with the one in an inertial frame.

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

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

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.
