An improved local oscillator modulation of modulated sampling scheme for multiple mono-pulse radar signals reconstruction

EURASIP Journal on Advances in Signal Processing, 2022
The modulated sampling scheme can intercept noncooperative signals distributed in a wide frequency band by using a single receiving channel, which is an efficient architecture in many radar and communication applications.

Performance analysis of hybrid MPAPM technique for deep‐space optical communications

IET Communications, 2021
A hybrid multiple pulse amplitude and position modulation (H‐MPAPM) scheme based on gradual multi‐pulse pulse‐position modulation (G‐MPPM) and multi‐level pulse amplitude modulation (M‐PAM) schemes is proposed for deep‐space optical communication.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Layered spatial modulation

EURASIP Journal on Wireless Communications and Networking, 2018
In this paper, we propose a layered spatial modulation (L-SM) scheme that combines a multi-layered coding scheme with the spatial modulation. At each antenna selection, the number of active transmit antennas equals the number of layers. The proposed L-SM

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
