Degrees of Freedom of the Wireless X-Network Assisted by Intelligent Reflecting Surfaces

IEEE Open Journal of the Communications Society, 2023
In this paper, we study the DoF of the time-selective $M\times N$ wireless $X$ -network assisted by an IRS. It is well-known that the DoF of the $M\times N$ wireless $X$ -network is ${}\frac {MN}{M+N-1}$ .

Internet of Intelligent Reflecting Surfaces (IoIRS)

CoRR
Intelligent Reflecting Surfaces (IRS) are anticipated to serve as a key cornerstone of future wireless networks, providing an unmatched capability to deterministically shape electromagnetic wave propagation. Despite this potential, most existing research still considers the IRS merely as a standalone physical-layer component, controlled by transmitters.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
