Multi-Stream Transmission for Directional Modulation Network via Distributed Multi-UAV-Aided Multi-Active-IRS [PDF]
IEEE Open Journal of the Communications SocietyActive intelligent reflecting surface (IRS) is a revolutionary technique for the future 6th generation mobile networks. The conventional far-field single-IRS-aided directional modulation (DM) networks have only one (no direct path) or two (existing ...

Two Low-Complexity Efficient Beamformers for an IRS- and UAV-Aided Directional Modulation Network
Drones, 2023 As excellent tools for aiding communication, an intelligent reflecting surface (IRS) and an unmanned aerial vehicle (UAV) can extend the coverage area, remove the blind area, and achieve a dramatic rate improvement.

Communications in Algebra, 2020 Recently, in a series of papers "simple" versions of direct-injective and direct-projective modules have been investigated. These modules are termed as "simple-direct-injective" and "simple-direct-projective", respectively. In this paper, we give a complete characterization of the aforementioned modules over the ring of integers and over semilocal ...

CXCL14 is no direct modulator of CXCR4 [PDF]
FEBS Letters, 2014 C‐X‐C motif chemokine 12/C‐X‐C chemokine receptor type 4 (CXCL12/CXCR4) signaling is involved in ontogenesis, hematopoiesis, immune function and cancer. Recently, the orphan chemokine CXCL14 was reported to inhibit CXCL12‐induced chemotaxis – probably by allosteric modulation of CXCR4.

Sparse Antenna Array Based Positional Modulation Design With a Low-Complexity Metasurface
IEEE Access, 2020 Positional modulation (PM) has been introduced recently where a given modulation pattern can only be received at certain desired positions. To achieve it, the multi-path effect is exploited for positional modulation with the aid of metasurface acting as ...

New Journal of Physics, 2007 A search technique locating network modules, i.e., internally densely connected groups of nodes in directed networks is introduced by extending the Clique Percolation Method originally proposed for undirected networks. After giving a suitable definition for directed modules we investigate their percolation transition in the Erdos-Renyi graph both ...
