Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)
Advanced Engineering Materials, EarlyView.Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Capacity of MIMO channels with antenna selection
, 2008 —This correspondence studies the capacity of multipleinput–multiple-output (MIMO) channels in the presence of antenna selection. Antenna selection reduces the complexity of the radio devices and requires only a small amount of channel state feedback. For

Secure Transmission Based on Antenna Selection for Network Coding System
Dianxin kexue, 2015 In order to improve the secrecy capacity of analog network coding system, antenna selection based transmission scheme was investigated. The selection criteria for the source nodes and relay nodes were proposed over a slowly varying channel.

Asymptotic capacity gain of transmit antenna selection
, 2003 Antenna selection provides a low-cost low complexity solution for MIMO systems, in particular transmit antenna selection exploits partial knowledge of the channel that can be made available without excessive feedback bandwidth.

Nondestructive Testing of Welded Composite Metal Foams
Advanced Engineering Materials, EarlyView.X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
