Vestibular modulation of spatial perception [PDF]

open access: yes, 2013
Vestibular inputs make a key contribution to the own sense of spatial location. While the effects of vestibular stimulation on visuo-spatial processing in neurological patients have been extensively described, the normal contribution of vestibular ...

Multi-Set Space-Time Shift-Keying With Reduced Detection Complexity

open access: yesIEEE Access, 2016
In this paper, we propose a novel multi-set space-time shift keying (MS-STSK) technique, where the source bits are conveyed over two components, namely, by activating one out of MQ dispersion matrices of STSK and M antenna combination of the Nt available

Modulation of gyrosynchrotron emission in solar and stellar flares by slow magnetoacoustic oscillations [PDF]

open access: yes, 2006
Gyrosynchrotron emission generated by non-thermal electrons in solar and stellar coronal flares can be efficiently modulated by slow magnetoacoustic oscillations in the flaring loops.

Labeling Diversity for Media-Based Space-Time Block Coded Spatial Modulation

open access: yesIEEE Access, 2020
Media-based space-time block coded spatial modulation (MBSTBC-SM) combines the advantages of media-based modulation (MBM) and STBC-SM. Meanwhile, labelling diversity (LD) has been applied to STBC-SM and improve the error performance.

Reconfigurable Intelligent Surface Enabled Spatial Modulation for Visible Light Communications

open access: yesIEEE Photonics Journal, 2023
An important issue in visible light communications (VLC) is how to boost up the system throughput even when the line-of-sight (LOS) link is blocked by obstacles. In this paper, we propose reconfigurable intelligent surface (RIS) based spatial modulation (

Modulation of Kekul\'e adatom ordering due to strain in graphene [PDF]

open access: yes, 2017
Intervalley scattering of carriers in graphene at `top' adatoms may give rise to a hidden Kekul\'e ordering pattern in the adatom positions. This ordering is the result of a rapid modulation in the electron-mediated interaction between adatoms at the ...
