Amplification of brightness variability by active-region nesting in Solar-like stars
(Iop Publishing Ltd, 2020)
Kepler observations revealed that hundreds of stars with near-solar fundamental parameters and rotation periods have much stronger and more regular brightness variations than the Sun. Here we identify one possible reason ...
Code-index modulation aided quadrature spatial modulation for high-rate MIMO systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2019)
In this correspondence paper, a novel code-index modulation (CIM) aided quadrature spatial modulation (QSM) scheme, called CIM-QSM, is proposed for highly spectrum and energy efficient multiple-input multiple-output (MIMO) ...
An experimental and analytical study on the influence of superhydrophobic micro-textured surfaces on liquid wetting phenomena
