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

open access: yesFEBS 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 ...

Passive Localization Through Channel Estimation of On-the-Air LTE Signals

open access: yesIEEE Access, 2019
Wireless communication signal is a kind of coherent illuminator, and it can shed light on surrounding environments. The mobile terminal receives the signal and estimate the propagation channel, and can sense the moving objects passively. The localization
